Z '0 all-whom it may concern:

Be it known that I, FRANKLIN KNIGHT KENNEDY, Jr, lieut., Ordnance Dept. U. S. A.., a citizen of the United States,stati0ned at.

ficers or employees in prosecution of work for the G-overnmenh'or any other person in the United States, Without payment to me of any royalty thereon. 1 o

The subject of this invention is a'target frame upon which the usual target may be mounted. 1 v p In target shooting it is customary to have attendants or markers 'stationed'behind' the protecting butts whose duty it is to lower the target, mark the location of theshotand again raise the target. 'At present it is usual to have two attendants assigned to'thi s duty oreach target. j

The present lnvention aims toprovide a target frame whlch 1s semi-automatic mac-i tion and which may be handled by one attendant with ease and facility.

I WVith these and other objects in view the invention resides the novel arrangement and combination of parts and in details of construction hereinafter described' and claimed, it being understood that changes in the precise embo'dimentof the invention; herein disclosed may bemade within the scope of what is claimed without departing from the spirit of the invention.

One practical embodiment of theiinvention is illustrated in theaccompanying drawings, wherein:

Fig. 1 is a view in front elevation of a target frame constructedin accordance with my invention; 7

Fig. 2 1s a plan view of the frame with the carriage in place therein, the Lip-rights of the frame shown in section;

Fig. 3 is a view in vertical longitudinal.

section of the treadle boX or pit.

Referring to the drawings by numerals of reference In carrying out my invention I provide uprights 10, preferably formed of channel iron, which may be secured in place upon a suitable base by the foot brackets 11. Diagonal braces 12 have ends secured to the uprights 10 and thelr upper ends secured to collars 13, which encircle a rod or shaft 1t bridging the space between the uprights and having its ends supported in clamps 15 se cured to the uprights. Mounted for rotation upon the shaft 14; is a sprocket wheel 16 which is held against longitudinal. move 'ment upon the shaft by the collars 13.

Mounted for vertical reciprocation in the uprights is a carriage comprising upper and lower "longitudinal bars 17 suitably connected as by. riveting to the end bars 18, which bars are preferably made of channel lIOZL' For the'purpose of strengthening the carriage braces 19 may be: connected to the upper and lower longitudinal bars Secured to the upper bars 17 adjacent each end thereof is a stirrup 2'0, and secured to the lower bars 17 adjacent each end thereof and m vertical alignment. with the stirrupi20 is a stirrup 2lforined with: an inturned underlying plate 22. The stirrupsQOand 21- are adapted to receivethe standards 23 of the target 24: the inturned plate '22 serving'to prevent the. standards falling through the st1rrups. i Mounted on each end bar 18'of the carriage is a pair of rollers 25 "adaptedzto engage the front: or rear flange tof theupright lOand between such pair 'o f.roller s is also mounted a roller 26 adapted toengage-the end of the'upright .10. The purpose of these rollers is'to support the carriagebetween the uprights without undue play and at the same time permit the'carriageto be easily J raised and. lowered.

Brackets 27 may be secured within'the channels of the uprights 10 for thepurpose of limiting the upward movement of the car-' 'riage and so prevent the chainfrom jumping from the sprocket wheel 16 when the carriage rises. Y

A. sprocket chain preferably of Y formation,has its arms 28 connected to the lower bar 17 of the carriage and the portion 29 passed over the sprocket wheel 16 with its end connected to a counter weight 30. The counter weight 30 may be of any suitable substance but is conveniently made of concrete which may be chipped ofl" to reduce the weight or added to'when it is desired to increase. the weight. I V

Means are provided for raising and lowering the carriage, consisting of a treadle box 31 in which is provided a fulcrum block 32 on which is fulcrumed a lever 33. Connected to one arm of the lever 33 is a foot plunger and to the other end of the arm a push rod 35, while to the same arm and between the push rod and, the fulcrum of the lever is connected at second push rod 36 formed with a forked upper end 37 adapted to receive and form a rest for the lower bar 17 of the carriage when the carriage is in lowered position. The frame may' have attached thereto the usual supporting bar 38 held by a brace 39 inwhich bar are journaled rods -"l0 carrying at their upper ends the signals l1.

In practice the invention is operated in the following manner. 7

To lower the carriage the attendant steps upon the foot plunger 34-, forcing the same downwardly, thereby locking the lever and forcing the push rod 35 upwardly. As the push rod 35 rises it elevates the counter weight 30 a sufficient distance to permit the Weight of the carriage and the chain to overbalance the counter weight and the carriage descends, the lower bar of the carriage coming to rest in the fork of thepush rod '36.

V17 hen it is desired to again raise the carriage the attendant once more steps on'the foot plunger 34, forcing the push rod36 upwardly and elevating the carriage a suiticient distance to permitnthe weight .of the chain and the counter weight-30 to over- ,balance the carriage which will cause the counterweight to descend drawing the carriage to its upper position. 7

Having thus described my invention what Iclaim asincw and desire to secureby Letters Patentfis: i

1'. A target frame, including channel iron 1 u ri hts a rod brid in the soace between carriage and engageable with the webs of I the uprights, stirrups on the carriage to receive the standards of a target, stops secured I to the uprights for; limiting the upward movement of the carriage, -a counter weight,

a sprocket chain passing over the wheel and connected to the carriage and the counter welght, a treadle box, a lever fulcrumed 1n the tread le box, a foot plunger connected to one end of the lever for rocking thesame upon its fulcrum, a push rod connected to the other end of the lever and adapted to engage the lower face of the counter weight to raise the counter weight when the foot plunger is depressed and a second push rod connectedv to the lever between the fulcrum and the first push rod, having a formed upper end to receive and straddle the lower bar of the carriage'when the/carriage descends.

2. A target frame, including channel, iron uprights, a rod carried byptheuprights and bridging the space between the uprights, a sprocket wheel mounted for rotation on the rod, a carriage mounted for vertical reciprocation between the uprights, stops for lim- 7 for operating the lever to, alternately thrust the 7 counter weight and the carriage upwardly. I

3. The combination with. atarget frame, including a reciprocable carriage,- of' a treadle box, a lever fulcrumed in said'box,

a foot plunger connected to one arm of the lever, a push rod connected to the other arm'of the leverto lower the carriage when the foot plungeris depressed and a push rod connected: t0 :.tl16 lever to raiset-he carriage w-hen'the foot plunger is again depressed.

4:. The combination with a target frame including a reciprocable carriage, of a lever, a foot plunger connected to :thelever and push rods connected to: the lever to 'alternately'lower and-raise the carriage whenthe foot plunger is depressed.
