To all /wwm t may concern:

Be it known that I, FRED KIMBLE, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Im rovements in Ball-Traps, of which the following is a specification.

My invention relates to a trap for throwing disk targets generally known as clay pigeons.

It is an object of this invention to provide a superior construction of a trap in which the throw arm is moved into active position by means of a single pulling means operated at a distance. The pulling means is connected to a flexible means wound about the pulley provided with a cam engaging a crank arm which puts the throw spring under tension. The throw arm is locked when in active position and released when the pulling means is moved in an opposite direction, the release of the throw arm taking place subsequent to the winding up of the flexible means about the pulley which is effected by a retractive spring. At the moment of release of the throw arm there are no parts or elements of the machine which are likely to interfere with the action of the same, and consequently a quick clean throw of the target disk is effected.

It is another object of this invention to provide a target trap which is simple of construction, positive in action, and not liable to get out of order.

With the above and other objects in view which will appear as the description proceeds, my invention consists in the construction, arrangement and combination of parts hereinafter described and claimed.

In the accompanying drawings, I have illustrated a convenient and practical embodiment of my invention, and in which:

Figure 1 is a side elevation of the apparatus.

Fig. 2 is a plan view of the target trap.

Fig. 3 is a side elevation of the target trap taken from the other side of that shown in Fig. l and with the throw arm end in inoperative position.

Fig. i is a similar' view with the throw arm in active position.

Fig. 5 is a rear view of the trap with parts broken away.

Fig. G is a section taken on line 6-6 of Fig. 2.

Fig. 7 is a section taken on line 7--7 of Fig. 3.

Fig. 8 is a horizontal section taken on line 8-8 of Fig. 5.

Fig. 9 is a section on line 9 9 of Fig. 2.

Fig. 10 is a horizontal section taken on line 10-10 of Fig. 6.

Referring to the drawings, 10 designates a pit in which the trap is located. A horizontal base plate or plank 11 is provided on which the trap is securely bolted. The trap comprises a turn table base plate 12 secured to the base or support 11 on which a rotatable plate 13 is mounted on a central pivot pin 111, extending upwardly from the base plate 12. A guide pin 15 depending from the rotatable plate 13 extends into an arcuate guide slot 16 of the base plate l2. A pair of upstanding lugs 17 oppositely arranged, f

support the target frame 18 by means of bolts' 19. Secured adjacent to the lower ends of the frame 18 and fast to the rotatable plate 13 is a pair of depending stirrups 2O adapted to be engaged by the feet of the operator for oscillating the rotatable plate 13 and the frame 18 carried thereby in the usual manner. The inclination of the frame 18 from the vertical may be adjusted by means of an adjuster arm 21, pivoted at one end of the frame 18, and secured to a supporting plate 22, fast to the rotatable plate 13 at the other. A pair of lock nuts engage the threaded end of the adjuster 21` at opposite sides of the supporting plate 22. By loosening the bolts 19 and the nuts 23, the degree of inclination of the frame 18 may be adjusted, and by screwing the bolts and the lock nuts into place the frame may be held securely in its adjusted position. From the upper end of the frame 18, a shaft supporting arm 24 extends at right angles thereto at the outer end of which a bearing for a shaft 25 is provided. The throw arm 26 is rigidly mounted at the upper end of the lshaft 25 and carries at its outer extremity, a target carrier 27. Referring to Fig. 6 'it will be seen that shaft 25 is rotatably mounted in a sleeve 28, the lower ends of said shaft and said sleeve extending below the arm 24. At the lower extremity of the shaft 25 a crank arm 29 is keyed, which eX- tends in opposite directions from the shaft. At one extremity of the crank arm 29, a pin 30 is secured to which link 31 is connected, and spring 32 is attached thereto at one end and to a stud 33, secured to the frame 18 at the other. The lower section of the sleeve 28 is reduced in diameter and provides a bearing for Va grooved pulley 34 loosely mounted thereon. The end of a chain 36 is secured to a cam shaped winding member 37, fast to the pulley 34. The lower face of the pulley 34 is provided with a dog 38, adapted to engage as the pulley is rotated with a crank actuating pin 39, projecting upwardly from the extremity of the crank arm 29 remote from the end of the throw spring32. A coiled retractive spring 40 fast to the arm 24 at one end and encircling the sleeve 28 and fast to the pulley 34 at the other, tends to 'wind the chain 36 about the'pulley 34.

The outer end of the chain 36 is connected to a pulling rod 41 by a link 42 and a link plate 43. The pulling rod 41 is connected to a manually operated lever 44 of the second class, preferably locatedl at the place'where f the marksman stands to clothe shooting.

ying

A pair of supporting arms 45 having their upper ends pivoted in spaced relation to a rearward extension 46 of the frame 18 and their lower ends pivoted to the link plate 43, serve to support the pulling'means and act as a release mechanism for the throw arm 26, presently to be'described. Y

rlhe throw arm 26 is provided with a downwardly depending lug or dog 4T, havan inclined face andy adapted to be engaged by a latch 48, mounted for vertical movement in a socket 49 in the upper end of the frame 18. A coiled spring 50 confined between the bottom .of the socket 49 and the latch tends to move the same upwardly. A horizontal pin 51 fast to the latch 48n and projecting through an aperture in the frame 18 outwardly therefrom, is engaged in the fork end of a latch release lever 52 ful- 'crumed to the frame 18. The other end of saidV lever is provided with a bearing yface 53 adapted to be engaged by a cam shaped trigger 54 projecting from and integral with the upper end of the supporting arm 45 adjacent thereto. The angle and the shape of the cam shapedv trigger 54 are so chosen that the latch releasing lever 52 will not be actuated until after the chain 36 has been wound upon its pulley 34.

Referring now to the target carrier 27, the same consists of a targetr supporting base plate 55 secured to the outer end of the throw arm 26. The outer side 'of the targetsupporting plate, that is to say the one describing the greatest circle in its rotary movement is provided with a slide rail 56, which consists of a metal rplate parallel to and slightly spaced from? the upper face of the base plate 55. A strip of rubber 57 is secured along theunder face of the slide rail 56, said strip of rubber projecting a slight distance beyond the inner edge ofthe slide rail. A curved target supporting rail 58 is mounted in parallel and spaced relation to the base plate 55 and oppositely disposed from the slide rail 56 at the inner end of said plate. At the inner end of the slide rail 56 and on the under face of the strip of rubber 57 is a small leaf spring 59 adapted to engage a circumferential flange of the target or clay pigeon 60.

rThe operation of the target trap is as follows: The yoperator straddl'es the seat 61 disposed to the'rear ofthe trap and above the pulling rod 41. .Vhen the hand lever 44 is moved in the direction shown by the arrow in Fig.. 1, the chain 36 will be unwound from the pulley 34' against the ten- .under tension. A semi-revolution of the crank arm 29 causes the throw arm 26 to describe a semi-revolution in a eircular'path from the position shown in Fig. 3 to that shown in Fig. 4. As the throw arm 26 and target carrier pass over vthe .spring controlled latch 48, the latter will engage the dog 47 and'lock the arm in what may be termed vits active position. The operator now places a clay pigeon in the. target carrier. The attendant operatingthe lever 44 after having set thc trap, allows the same to move in the opposite direction. l'he retractive'spring 40 is of suiiicient strength to rotate the'pulley 34, winding the chain 36 thereon, and also moving the pull rod` 41 connected therewith. VThe attendant retains his grip on the lever at the point when the continued backward movement Vof the lever would spring the trap. A few trials will indicate to the attendant the exact positrap will be sprung instantly. Releasing the lever 44,'the action of the spring 40 will move the pull rod'41, thereby causing the trigger 54 to actuate the latch releasing lever 52, withdrawing the latch48 and allowing the throw spring 32 to swing the throw arm 26 about its pivot and to throw the target. 1t should be noted that at the moment of release, the movable parts such as the chain 36, which might interfere, are out of the way and a clean, swift'throw of the target is effected.

The target 60 is heldin place bythe supportingijaw 58 andthe spring 59.- Just as soon as the centrifugal forces overcome the resistance of said spring, the target is thrown outwardly, the friction of the rub- -ber strip in the Aslide railr56 retarding that end of the target and' thereby causing the same to rotate swiftly as shown by the arrow in Fig. 2.

It is therefore seen that I have constructed a target trap simple of construction, in which the throw spring is actuated by means independent of the throw arm, that the throw arm is released only after the parts liable to interfere with it are out of the way, thereby effecting a clean, quick throw of the target.

While I have shown the preferred construction of thetrap as now known to me, it will be understood that various changes in the arrangement, construction and combination of the parts may be made by those skilled in the art without departing from the spirit of my invention as defined by the appended claims.
