vice through the medium of which broken.

rivets may be expeditiously removed from buggy-bow sockets and this with but little effort on the part of the user of the device and without entailing any injury whatsoever to the buggy-bow socke a o With the foregoing in mind the invention will befully understood from the following description and claim, when the same are read in connection with the accom anying drawings, forming part of this speci cation, in which 4 Figure 1 is a view illustrating :my novel device in side elevation as pro erly positioned relative to a buggy-bow soc et from which a broken rivet is to beremoved. Fig. 2 is a detail view, partly in side elevation and partly in longitudinal section, of the forward portion of the device. Fig. 3 is a transverse section taken in the plane indicated by theline 3 3 of Fig. 1 looking in the direction indicated by arrows and showing the pin for dis lacing the rivets as connected with the screw in such manner that the screw is adapted'toturn inde endent of the pin.

. imilar letters designate corresponding parts in all of the views of the drawings, re-

erring to which .A is a portion of a buggy-bow socket from which is to be removed a broken pin B, having at one end the usual head C, and D is the frame of the device, constitutingthepresent and preferred embodiment of my invention. The said frame D is formed in one piece of metal suitable to the function of the device and comprises a main portion a, an arm b, reaching at a right angle from one end of the main portion a and having a bore a disposed longitudinally of the device and designed to receive the head of the rivet B after the manner shown in Fig. 1, an armd reaching at a right angle from the opposite end of the main portion a, and having a longitudinally-dis posed threaded aperture e,"alined with the ore c, and an upright f, extending upward from the main portion a at a oint intermediate the arms I; and d an preferably nearest to the arm l) and having a compara-- tively small longitudinally-disposed aperture 9, arranged in alinement with the longitudlnal centers of the bore a and aperture e. I n 6.0 practice the frame D is. designedto be used n the position illustrated in Fig. 1, when, as Wlll be readily apparent, the main portion a will form a convenient hold for the left hand of a the operator and the arms band (1, as well as the upright f ,will extend u ward from the saidmain portion a. I won (1 have it understood, however, that the frame D may be used in any other position suitable to the purpose'ofmy invention in the discretlon of the '70 operator. I

E is therivet-displacing pin of the device, which is referably of steel. "The said pin E is prefera ly provided with a tapered-forward portion h, and at a point adjacent to its rear end it has a circumferential groove '5, Figs.

2- and 3, for; a purpose presently set forth. The diameter of the major portion of thepm E is preferably slightly less than that of the guide-a e'rture g in the upright f, and hence 8 it will e appreciated that when the pm 1s moved forward rectilinearly, as hereinafter v pointed-out, it will be held against lateral deflectlon by the uprlght and will be reinforced by said upright w ile pressed against 5 the rivet to be displaced.

F is the screw of the device, the office of which is to powerfully push the pin E forward. The said screw F is of an exterior diameter to snugly fit in and engage the go threaded aperture 0 of frame D, and it is provided with a longitudinal bore 1', which s of a diameter slightly greater than that of the pin E and of the proportional length illustrated, this latter to permit the rear end 9 5 of the pin to abut against the end of the bore 1', so that strain is taken off the pin-securing screw, presently described, when the device is in use.

G is the pin-securing screw, which bears in u o the screw F and has its inner-end, arranged m the frame D the pin E willalso be moved no.

forward, but will not be turned about its axis. On the other hand, the pin E W111 hav e movement, and consequently it will be apbut one movement and that a rectilinear parent that when moved forward by the screw the pin E will be found highly eflicient in displacing rivets, such as B.

Any suitable means may be resorted to to facilitate turning of the screw F; but I prefer to provide said screw with ashank Gr, on which is a handle H, through the medium of which the screw may be turned by hand I and withthe expenditure of but little effort. i

Inthe practical use of my novel devicethe same is so arranged relative to a buggybow socket from which a broken rivet is to be removed that the socket rests at the inner side of the frame-arm b, and the head C of the broken rivet B is received in the inner end of the bore a in said arm. When the device is placed as stated relative to the buggybow socket, the pin E is in the position shown in Fig. 2, and after the described positioning of the device the screw F is turned forward through the aperture e in frame-arm d, when. the pin E,Which is moved forward by the screw F will engage .the end of the broken rivetshank and press the broken rivet out of the socket of the bow, and this without marring or injuring the bow in any manner whatso- I ever. Subsequent to the displac ment of i the broken rivet the screw F is turn d Quit ward to withdraw the pin E from the -:ocket in the bow. and then the improved device may be remo ed from the bow.

in znhllilen to the practical advai tages i hereinbefore ascribed to my novel device L it will be noted that the device is compact. i easily handled, and ex editiously operated with the expenditure 0 but little eiiort and is well adapted to withstai'id the rough usage j to which analogous devices are ordinarily subjected. Having described my invention, what 1 claim, and desire to secure by Letters Patent,

In a device for the purpose described, the

ed aperture alined with the bore in the first mentioned arm, and a guide reaching'laterally from the main portion, at a point inter mediate the arms, and having a sinoot-ha'pen ture com aratively small iirdiameteralined"' with the ongitudinal centers of the bore and threaded aperture; of ascrew bearing in the threaded aperture of the frame and having a longitudinal central bore extending rearward from its forward end and closed at its inner end, a smooth pin, of slightly less diameter than the smooth aperture of the guide on the frame arranged in said aperture and in the bore of the screw and having its rear end arranged to abut against the closed inner end of said bore and cooperating means on the screw and the pin for connecting the screw and the pin while permitting the former to turn independent of the latter.

in testimony whereof I have hereunto set my hand in presence of two subscribing wit- HQFSGS.
