ERNEST A. ROMAN ATTORNEYS 3,224,427 Patented Dec. 21, 1965 3,224,427 CRQSSBOW PISTOL Ernest A. Ronan, Florenton, Minn. Filed Sept. 14, 1962, Ser. No. 223,647 12 Claims. (Cl. 124-25) This invention relates to the general field of weapons and, more particularly, the instant invention pertains to string or thong-operated instruments of the aforesaid general classification.

One of the primary objects of this invention is to provide an arm in the nature of a crossbow which readily lends itself to archery practice against fixed or moving targets and which finds a high degree of utility when employed in the field hunting of game.

Another object of this invention is to provide a device of the crossbow type in which have been incorporated features of a conventional sidearm and of sub-machine guns in order that the crossbow may, optionally, be operated through the use of one or both hands.

The instant device is so constructed as to be used with arrows which are conventionally feathered in the same manner as arrows which are constructed for use with usual longbows.

A still further object of this invention is to provide a crossbow pistol with a telescopic sight whereby the crossbow pistol may be fired at stationary or moving targets with a high degree of accuracy.

It is still another object of this invention to provide a crossbow pistol of a collapsible type in order to facilitate its portability and the storage thereof when not in use.

This invention contemplates, as another and further object thereof, the provision of a crossbow pistol that is non-complex in construction and assembly, inexpensive to manufacture and maintain, and one which is durable 1n use.

Other and further objects and advantages of the instant invention will become more manifest from a consideration of the following specification when read in conjuntion with the annexed drawings, in which:

FIGURE 9 is a perspective view of the crossbow pistol, FIGURE 9 being drawn on a reduced scale and illustrating the bow with the arms thereof in their collapsed or inoperative positions.

Referring now more specifically to the drawings,reference numeral 10 designates, in general, a crossbow pistol constructed in accordance with the teachings of this invention. Thecrossbow pistol 10 is provided with astock 12 which is seen to be allochiral, and hence, the description of one section or portion is a description of the other.

Thestock 12 includes theforearm portions 12A, 12B from which dependforearm handle sections 14, 14 intermediate the ends thereof, andrear handle grips 16, 16 respectively. Each of thestock portions 12A, 12B has a longitudinally extending L-shaped groove 18, 18 formed therein. Thegrooves 18, 18 adjacent their respective ends terminate in a laterally offset and enlargedgroove 20, 20 which open downwardly at 22, 22 at a point immediately adjacent therear handle grips 16, 16. Thestock 12portions 12A, 12B are secured together by screws orrivets 24.

The connectedstock portions 12A, 12B adjacent their respective forward ends are notched, vertically, as at 26, 26 (see FIGURES 3 and 6), the notches being in open communication with thegrooves 18, 18. Extending transversely across the aforementioned forward ends of thestock portions 12A, 12B is anothersecuring rivet 28 which also serves as a pivot pin on which is pivotally mounted one end of an elongated substantially rectangularforward arrow rest 30, the other end of the latter having an arcuate arrow-receiving and supportingrecess 32 extending inwardly therefrom with its axis being substantially parallel to the longitudinal axis of thestock 12. To the rear side of the arrow rest 30 adjacent thepivot pin 28 is ahasp 34 which extends inwardly of thegroove 18, 18. Thehasp 34 has pivotally connected thereto aneye 36 formed at one end of an elongated substantially rigidcylindrical trigger rod 38 that extends longitudinally within thegrooves 18, 18. The other end of therod 38 terminates in aneye 40 pivotally connected to ahasp 42 which, in turn, is connected to thestem 44 of a bifurcatedrear arrow rest 46.

Thestem 44 includes upstandingdivergent arms 48, 48 and the lower end of the stem is threaded into the peripheral edge of a cockingdisc 50 eccentrically mounted on apivot pin 52, the opposed ends of the latter being supported on and connected to thestock portions 12A, 12B. As is seen in the drawings, thecocking disc 50 is supported above thegroove 28, 20 and the latter opens downwardly at 22, 22. It is to be observed that the threaded end of thestem 44 is received forwardly of thepivot pin 52 and that the cocking disc, when in cocked position, as shown in FIGURE 3, has a downwardly facingperipheral chord side 54. Fixedly secured to the cockingdisc 50 rearwardly of thepivot pin 52 is acocking handle 56 which, in all positions of the cockingdisc 50, projects upwardly and outwardly of thegroove 18, 18.

Extending transversely across thegroove 20, 20 and supported on thestock portions 12A, 12B is apivot pin 58 on which is pivotally supported the hub 60 having rigidly secured thereto one end of an elongated shank 62 of a sear 64. The other or forward-facing end of the shank 62 terminates in an upwardly-facing,laterallyoffset lip 66 which, when the cockingdisc 50 is in its cocked position, as shown in FIGURE 3, engages thechord side 54 forwardly of thepivot pin 52. Facing downwardly and away from thelip 66 is a protuberance, preferably a ball bearing 68. Coiled about the hub 60 areconvolutions 70 of ahelicoidal spring 72 having anend 74 engaged under the inner end of the stem 62 and its other end anchored in thegroove 76, 76. The arrangement is such as to constantly bias the sear 64 for clockwise movement about thepin 58, reference being made to FIGURES 3 and 4, whereby thelip 66 is maintained in constant contact with thelocking disc 50.

Apivot pin 78 extends transversely across thegroove 20, 20 above its opening 22, 22 and the ends thereof are supported on thestock portions 12A, 12B. The pin '78 has pivotally mounted thereon abellcrank trigger 80 having anupper arm 82 normally engaging thebearing 68 when the cockingdisc 50 is in its cocked position (see FIGURE 3), and a lower arcuately shapedtrigger arm 84 of conventional design. To the upper end of thetrigger arm 82 and below thepivot pin 78 is anchored oneend 86 of ahelicoidal spring 88, the latter having one of its ends connected to ahasp 90 secured to thestock portion 12B and thegroove 20, 20. As is seen in the drawings, thespring 88 constantly biases thetrigger 80 for clockwise movement about thepin 78 whereby thearm 82 constantly engages thebearing 68. Thetrigger arm 84 projects outwardly through the opening 22, 22 and is surrounded by aconventional trigger guard 90 connected to the underside of thestock 12 and to thehand grips 16, 16 as byrivets 92.

Set into thestock 12 adjacent the forward end thereof is an elongated substantiallytrapezoidal connector plate 94 which is disposed perpendicular to the longitudinal axis of thestock 12 and projects laterally beyond the remotely disposed sides of thestock portions 12A, 12B. Theplate 94 is fixedly secured in position bybolts 96 andnuts 98, the bolts extending through thestock portion 12A, 12B as is clearly seen in FIGURES 3, 4, 7 and 8. Theopposed ends 100, 100 of the trapezoidal plate are convergent in a forward direction. Theplate 94, adjacent to but spaced inwardly from its remotely disposedends 100, 100, has fixedly secured thereto arivet 101 having a circumferentially groovedupstanding head 102 to serve a function to be described.

Reference numeral 103, 103 (see FIGURE 7) denotes, in general, a pair of identical bow arm mounting brackets. Eachbracket 103, 103 includes a substantiallyrectangular socket 104, 104 having opposed top andbottom walls 106, 106, 108, 108, respectively, and an elongaterfront side wall 110, 110 and an opposedrear side wall 112, 112 of shorter length. Anend wall 114, 114 extends between therear side wall 112, 112 and thefront side wall 110, 110, and is connected to the latter intermediate its opposed ends leaving a frontend wall portion 110A, 110A. As is seen in the several drawings, the frontend wall portions 110A, 110A project, normally, when the bow is in operative position, toward each other.

Integral with theextension 110A, 110A and with theend wall 114, 114 is a pair of spacedbracket mounting ears 116, 116 and 118, 118, respectively, between which 4 is secured the opposed ends of theplate 94, the ears being pivotally connected to the latter by means ofpivot pins 120, 120.

The front end wall portion A, 110A adjacent the outer end thereof is bored at 120, 120 to loosely receive therethrough the threadedshank 122, 122 of aneye bolt 124, 124. The eye 126, 126 of thebolt 124, 124 is substantially annular in configuration and opens at its outer extermity into aloop 128, 128 of lesser diameter. As is seen in FIGURES 7 and 8, theloop 128, 128 is adapted to engage thegrooved head 102, 102 and is retained thereon by awinged nut 138 which abuts against the frontend wall portion 110A, 110A when the bow is in its operative position, as shown in the figures.

Thebow arms 132, 132 have substantially the classical configuration and are rectangular in transverse crosssection. The inner end of eachbow arm 132, 132 is received within thesockets 104, 104, respectively, and is locked therein by transversely-extendinglock rivets 134, 134. The outer ends of thearms 132, 132 are notched at 136, 136 to receive the looped ends 138, 138 of a conventional ring, cord orthong 140.

While not necessarily an adjunct to this invention, but in the interest of the accuracy of the firing of thecrossbow pistol 10, an L-shapedsupport 142 is provided, the support having afoot portion 144 thereof fixedly connected to theplate 94, and having anupstanding leg portion 146. The mounting bracket for thetelescopic sight 148 is denoted at 150 and includes an elongated substantiallyrectangular plate 152 to which is secured thetelescopic mounts 154, and from a longitudinally extending marginal edge of theplate 152 depends asemi-circular flange 156 which is provided withscaler indicia 158 adjacent its arouate edge. Theflange 156 is secured in a selected adjusted position on theleg 154 by means of abolt 160 andwing nut 162.

Reference numeral 164 indicates a conventional archers arrow having an elongated substantiallycylindrical shank 166 provided with a tippedhead 168 at one end thereof, the other end having a conventional bolsteringnotch 170 formed therein. Adjacent the last-named end the shaft is feathered as at 172.

Having described and illustrated the instant invention in detail, the operation thereof is deemed to be obvious to those skilled in the art. However, and in the interest of clarity, the operation of this crossbow pistol is summarized below.

Assuming that thecrossbow pistol 10 is in its operative position as is illustrated in FIGURES 1, 2, 3, 7 and 8, the crossbow pistol being cocked and armed with an arrow 164. In the operative position, the operator has drawn thebowstring 140 for engagement behind thearms 48, 48 of thearrow rest 46. This causes thebow arms 132 to assume the full-line positions shown in FIGURE 2. The arrow 164 is placed in therecess 32 with the tippedend 168 lying immediately adjacent thereto, and the other end of the arrow 164 isrested between thearms 48 with thebowstring 140 engaged within thenotch 170.

The archer now takes aim with thecrossbow pistol 10 by grasping thehandles 14, 14 and 16, 16, with or without use of thetelescopic sight 148, and a finger is engaged across thetrigger arm 84. When the desired sighting has been made, thetrigger arm 84 is pulled toward thehandle grip members 16, 16 in a counterclockwisedirection with respect to FIGURE 3, causing thearm 82 to pivot in the same direction about thepivot pin 78 and to escape below the hearing orprotuberance 68 of the sear 64. With the sear 64 thus released, the tension of thebowstring 140 against thearms 48 of the rest 46 tends to cause thecocking disc 50 to rotate in a counterclockwise direction about thepin 52, and in so doing, disengages' theperipheral chord side 54 from thelip 66. With this pivotal movement, therod 38 is urged toward a forward position, causing, substantially simultaneously with the movement of thecocking disc 50, a pivotal movement in a counterclockwise direction of thearrow rest 30 in a counterclockwise direction. It will be understood, of course, that at the time the arrow rests 30, 46 initiate and continue their above-described movement, thebowstring 140, now being released from restraint by thearms 48, forces the arrow 164 forwardly and remains within thenotch 170 until thebow arms 132 reach their maximum forward position illustrated in dotted lines in FIGURE 2. At this point, the advance of thebowstring 140 is halted and the inertia of the arrow 164 continues to propel the same toward the selected target.

With the arrow 164 discharged, the component elements of the crossbow pistol assume their relative positions, as illustrated in FIGURE 4 of the drawings. To re-arm thecrossbow pistol 10 it is only necessary that the archer press against the cockinghandle 56, using his thumb or a finger, to efiect a rotation of thecocking disc 50 in a clockwise direction about thepivot pin 50 whereby thelip 66 of the sear 64 is re-engaged below thechord side 54 of the cocking disc and is retained thereagainst under the influence of thehelicoidal spring 72. As thelip 66 moves upwardly against thechord side 54, thearm 82 of thebellcrank trigger 80 will follow, moving in a clockwise direction under thebearing 68 until it comes to rest in the position shown in FIGURE 3. It will be noted that the outer end of thearm 82 is cam-shaped, as at 82A, having a rising contour as the arm is pivoted in a clockwise direction, whereby the arm is locked against escape below thebearing 68. The pivotal movement of the bellcrank trigger is, of course, furnished by virtue of thehelicoidal spring 88. Thebowstring 140 is now drawn rearwardly for engagement behind thearms 48 of thearrow rest 46, and the crossbow pistol is bow ready to receive the arrow 164 in the manner described above.

In order to facilitate the portage and storage of thecrossbow pistol 10, thebow arms 132 are collapsible to the positions illustrated in FIGURE 9.

Assuming that thecrossbow pistol 10 has been dis charged and that thearms 132, 132 have moved to the dotted-line position shown in FIGURE 2, and that the other component elements of thecrossbow pistol 10 are resting in the positions shown in FIGURE 4, thewing nuts 130, 130 are now unloosened from theeye bolts 124, 124. This permits theeye bolt 124 to be shifted axially so as to disengage theloop 128 from thegrooved head 102 and to circumscribe thehead 102, 102. It will be recalled that the bore oropenings 120, 120 loosely received the threadedshank 122, 122 of theeye bolt 124, 124, and with the annular eye 126, 126 in the described position, the same may be lifted over the upper terminal end of therivet 101 and the eye bolt is then shifted axially toward theextension 110A to effect complete disconnection between theeye bolt 124, 124 and the upper ends 102, 102 of therivets 101, 101. Thearms 132, together with theirrespective sockets 104, 104 are then pivoted about thepivot pin 120, 120 to assume the positions shown in FIGURE 9, thearms 132, 132 extending axially of theshank portions 12A, 12B. Thetelescope 148 may be dismounted by removing the bolt or screw 160 through the disconnection of thewing nut 162.
