Patented Oct. 28, 1941 UNITED STATES PATENT OFFICE FLASHLIGHT BILLY WiuiamM; Power, Milwaukee, Wis. ApplicationMarch 1, 1939, Serial No. 259,139 .4 Claims; (01. 240- 642)" This invention relates to billy clubs ingeneral and more specifically to a billy club ornight stick into which is built a flashlight unit.

My primary object is to provide a billy club containing therein a dry battery operated flashlight unit which is so mounted 'in the club as to be fully protected against damage while the club withstands rough treatment, as when it is dropped or thrown against a hard surface or when used as a weapon. I

' Another object of my invention is to provide in a club of this type a control switch so constructed and positioned that although it can: be

quickly operated by a user when once set in a given position, it is notapt to change that 'position accidentally. v A further object or my invention is to provide a flashlight billy club which can be manufactured at relatively low cost and which possesses substantially the strength of an ordinary club of;

this type not containing a flashlight unit.

Further objects ofmy invention will become apparent as the description, of the same prO-' gresses. I

Like parts are identified by the same (reference characters throughout the drawing. e

While I do not claim to be the first 'to combine a flashlight and a billy club, I do claim to be the first to produce a club of this type that will consistently function after being subjected to the rough treatment such a club is apt to be given.

The club proper may be of regulation size, design and material and includes a cylindrical club-like barrel portion I2 to which is screwed acap 8, ahandle 13 which may be integral with thebarrel portion 12 and a cap H] which is slidably mounted on handle l3. Cylindrical portion I2 is provided with a central chamber [4 which extends through the barrel to handle l3 where it leads into a center bore l6 which extends through handle I3. Housing element [8' is com-- prised of a cylindrical portion I1, an integral l9, and a plugged end ZU threaded end portion with a small center opening, said housing being held in bore. I4 by means of a=pressed fit as well as by other means which will be subsequently" thereby securing tube 2-2 inbore 16. This meth odof construction affords additional means to aid in securing housing l8 in bore l4. 7

Flashlight cells 34- and 35 are disposed withinhousinglB where they are held in pressure engagement between di-electric washer 39 and bulb assembly unit H by the tension of springs-3l, 32 and 38. Bulb assembly II is comprised of a U- shaped'bracket 40 to which is secured a drum shaped housing 4| di-electric disks 42- and 43 between which are secured termini of springs 3| and 32 by means of rivet 44'.Disks 42 and 43 are provided' withapertures 45' and 46, respectively, through whichsprings 32and 3| arcuately project in'a V-shape to contact terminal 64" ofbulb 26 and terminal 63 ofcell 34, respectively. 7

As shown in Fig. 3, bracket 4il'of assembly 1H fits securely within the threaded end of tube 18' by reason of a close fit plus spring tensionwhich is introduced between saidbracket 40 and the inner periphery ofhousing 18 by reason of the arms of said bracket being normally divergent from itsbase 48, When the unit is assembled as shown in Fig. 1, movement of the bulb assembly H is restricted in a direction toward lens'e 25-by reason ofbracket 40 abutting annular shoulder"410i cap 8. v

Bolt extends throughhandle bore tube 22 and is provided at the housing end with screw" head"5l* to which'is secured contact sp'ring52 and" at the opposite end with threadedsection 54. Theintermediate section 53 ofbolt 50* is arcuately curved to frictionallycontact tube 22 whereby to prohibit axial movement until pressure is applied to control knob In, said control knob being secured by means of threadedinsert 55 to threadedsection 54 ofbolt 50. Thecontrol knob 10 is provided with acylindrical socket 56 which fioatably retainstwoin which is slidably disposed thecompanion bearing section 51 of handle l3.

The operation of the device is as follows: When control knob I is sufiiciently pressed in toward handle l3,spring 52contacts terminal 58 ofcell 35 and an electric circuit is closed throughcurved section 53 ofbolt 50,sleeve 22, housing l8, bracket I I,socket 28,bulb 26, springs 32 and 3|,cell 34,springs 38 and 38, and back tocell 35, thuslighting bulb 26. Lense focuses the light rays emitted bybulb 26 and passes them divergently through circular opening 21. To extinguish the light, the user pulls outwardly on knob l0 thereby pullingspring 52 out of contact withcell 35.

Abattery cushioning device 9, Figs. 1 and 5, comprising di-electric disks 60 and BI between which are fastenedsprings 38 and 38, absorbs shock between the cells and prevents the center terminal of cell from denting in the adjacent end wall ofcell 34. As in the ordinary flashlight, rough usage of the club will force the relatively heavy cells axially as radial movement is restricted by their retaining housing. Movement of cells in a flashlight often causes breakage of the bulb, the bulb socket, reflector, or shock spring device. In the present device, I overcome any possibility of such damage by provision of a shock absorbing mechanism of sufficient strength to readily absorb all axial battery movement without damage to any of the parts. For this reason, I prefer to constructbracket 40 and drum 4| of bulb assembly ll out of heavy brass or the like. Floating springs 32 and 3| Will absorb all ordinary shocks without damage tobulb 26, but if a very severe shock causes an extraordinary depression of said floating springs, the front end wall ofcell 34 will contact the adjacent end of drum 4| wherecell 34 will come to rest before damage can be done to bulb 26 or tobracket 40. Movement of the cells in an opposite direction is restricted by di-electric washer 39. Hence, jamming ofcontact spring 52 bycell 35 cannot occur.

A user may, by recessing the control knob in the palm of the hand and grasping the handle y with the fingers, operate the control knob switch without the use of the other hand. This particular feature is highly desirable as there are apt to be times when a user such as a police officer or a night watchman might wish to operate the flashlight without using both hands, as, for example, during a tussle or while he is riding on the runningboard of an automobile. Mere pressure of the butt of the handle against any part of the body will close the switch.

In addition to thecushion member 9, I provide a spacer cushion between the margins ofbattery 34 and the edges of the drum 4| thus absorbing the longitudinal thrust in the line of cylindrical members best able to resist the thrust.

Most regulation billy clubs are made of relatively heavy material such as hickory wood, and I have found that my flashlight unit weighs about as much as the material removed from the club for the installation of the unit, therefore, little or no weight is added, and the user is thus relieved of the weight of an additional flashlight as Well as the inconvenience of carrying a relatively bulky item.

I claim:

1. A club comprising a barrel-like portion provided with a central chamber and a handle portion provided with a center bore leading to said central chamber,.the terminus of the handle provided with an annular bearing portion, a metallic sleeve disposed within said center bore, a distorted rod projecting through said sleeve and in frictional engagement with the walls thereof, a cap carried by the rod and provided with a cylindrical chamber for slidable mounting on the handle bearing terminus, a flashlight unit contained within said chamber, said unit including a dry cell, a bulb, and spring means for connecting the bulb with the cell, contact means disposed Within the chamber secured to the chamber terminus of said rod element in slidable relation to a contact terminal of said dry cell whereby to permit axial movement of the cap along a portion of the handle bearing to provide means available to a user for opening and closing the cell and bulb circuit.

2. In a device of the type described, a bulb mounting and shock absorber assembly comprising a U-shaped bracket, the base of which is secured to one side of a drum-like housing and the bracket arms projecting from the housing in substantially an axial direction but diverging slightly from the base, a bulb socket mounted centrally on said base and projecting between said arms axially with respect to said drum and adapted to receive a bulb, the base terminal of which projects through an opening provided in said bracket base and two di-electric washers provided with apertures and disposed to float within said drum,
