' Be. it known that I, JAMES C. PARMERLEE, a citizen of the United States, residing at Sedalia, in the county of Pettis. and State of Missouri, havein'vented new and useful Improvements in Ball-Target Throwers, of which the following is a specification.

Hy invention relates to improvements in target-throwing traps, and in it the spring or throwing-lever is set orengaged with the trigger by the operation of a suitably-constructed leverage with proper connections, and simultaneous with the setting process deposits the object to be thrown, such as a ball in a cup or other proper receptacle.

The objects of my improvements are, first, to provide a self-setting and self-loading, or automatic setting and loading, rotary trap, which revolves in a complete circle, whirling around as many times as may be desired, in-

, dependentoftheloadingattachment; secondly,

to provide a trap which may be operated from a distance, dispensing with the services of an attendant at or near the trap thirdly, to provide a trap to diminish the dangers incident to the practice of shooting at target-balls with an attendant at or near the trap; fourthly, to provide a trap to dispose of thedanger of being struck by the spring-lever, for in loading hall-traps by hand serious consequences have resulted by the spring slipping while being set and after being set, and the spring in many instances has dealt furious blows in the face or on the person of those engaged in trapping, while even more serious consequences have resulted from the attendant being struck by a flying ball or the shot from some unskillful shooter; and, fifthly, to provide a compensating rotary self-setting and self-loading trap, which may be brought into position and the proper rotary movement imparted by positive and uniform motion, no springs being required to wind up the trap for another shot, the operation of setting the traps winding up the pulley-cord ready for another whirl? I attain these objects by means hereinafter described, and illustrated in the accompanying drawings, in which- Figure 1 is a vertical longitudinal section of the entire machine; Fig. 2, a detached perspective view of the trigger-trip. Fig. 3 is an end M view of the machine, and Fig.4 is a top view centric sheaves, O G, sustained in a horizontal.

position by a hollow shaft, D, to which they are keyed. inclined arm, E, and extends vertically through This shaft is an extension of an the rectangular frame, and is stepped in itsbase,so as to be free to revolve. From a hub, a, of the arm E,which extends beyond the 1101- low shaft, there rises a vertical post, F, perfo rated transversely, and supporting a bracket, G, which has a cushion, 6, preferably of rubber or some other suitable yielding material,in its face near its top, and which is vertically ad justable by a pin projecting from its arm and entering one of the perforations in the post,to which it is securely held by a collar or clasp, c, encircling both the arm and the post. The cushioned bracket on the post is intended to serve as a stop to the forward movement of the" bent lever H,whieh carries a cup, I, at one end, and is formed near the other end into a coiled spring, I, and at that end connected to the arm E by an angle of the spring itself passing through alug or ear on the arm, and the'con nection of the two parts is strengthened by'a sliding collar or clasp, d, encircling both the arm and lever. The cup at the end of the lever is to hold the ball that is to be projected. by the force of the spring at the other end, and until the time for projecting the ball the lever is held down by a trigger, J, pivoted to the end of the heel of arm E, opposite to the side of post F, and formed with a hook to pass over the lever, and with a heel, e, to enter a slot, f, in the arm g of the trigger-tripping tube K.

This tube passes through the hollow shaft D,

and is allowed a vertical play therein, so that when raised it will throw or trip the trigger from the spring-lever, and allow the latter to be thrown forward to project the ball by the tension of the spring till the lever strikes against the elastic cushion in the stoppingbracket. The tripping-tube is raised by a bell crank lever, L, pivoted below the rectangular frame, so that when one arm of it is drawn down by the rope or chain M, the other arm will be thrown up against the lower end of the tripping-tube, so as to raise the latter and effeet the tripping of the trigger and releasing of the projecting orimpelling lever, after which the tripping-tube will drop down by gravity and restore the trigger to its normal position.

The projecting or impelling lever is drawn down to engage with the hook of the trigger by means of a chain, M, connected to the lever at the bend or point h, and extended down and around a grooved pulley, N, j ournaled in suitable bearings or standards, A, which pulley is operated through a large main pulley, O, on the same shaft, which latter pulleyis revolved by what will be designated a setting rope or chain, 1?, which-passes one or more. times around the latter pulley. The diiference in diameter of the two pulleys affords considerable leverage, so that notwithstanding the power of the spring to the impelling-lever, the latter is drawn down with much case against the beveled face of the hooked end of the trigger, thus pressing the latter outward till the lever has passed under the hook, when the hook, by the weight of its tripping-tube, is thrown over the lever, so as to hold the lever'down till released by throwing the crank-lever L against the trippingtube. This crank-lever is operated by what will be designated a trigger'eord, M, con nected to one arm of the lever and to a rope or chain, R, which will be designated the rotating rope. This rope or chain is connected to and passes around the pulley .G, and the con nection of the trigger-cord therewith is such that when the rope is wound around the pulley the trigger-cord hangs with slack enough to permit the impelling-lever to be revolved or rotated by drawing on the rotating rope before the trigger-cord is drawn taut enough to throw up the crank-lever. The amount of slack depends on the number of times the impelling-lever is to be revolved before being released, and it may be regulated by adjusting the trigger-cord along the rotating rope, the latter being provided with eyelets or rings for that purpose, and the number of times that the impelling-lever shall be rotated is regulated by winding the rotating cord one or more times around the pulley. After the leyer has impelled its ball it is returned to its normal position by a rope or chain, S, desig natedthe positioning-rope, connectedto the lower pulley, O, and passed around it the same number of times that the rotating rope passes around the upper pulley, but in the opposite direction, so that when either rope is drawn on the other rope will be wound around its pulley to the extent that the unwinding rope is withdrawn, and thus the impelling-lever is brought back to its normal position, and one rope has its slack taken up and is placed in position for operation by the operation of the other rope. The positioning-rope S is con-- nected at its outer end to the settingrope P by a coil or other spring, T, which has a hook at one end that engages with an eye or ring formed in or attached to-the setting-rope. The point at which the positioning-rope is connected to the setting-rope is such that when the positioning-rope has been drawn out as far as necessary to bring the lever back to its normal position the setting-rope may be drawn several inches (more or less) further to bring the lever into engagement with the trigger, the spring-connection between the two ropes permitting that to be done without liability of moving the cup on the lever too far to receive the ball from the delivering device. As stated, the slack of the positioning-rope will be taken up by drawing out the rotating rope, and the slack in the setting-rope will be taken up or wound around its pulley O by a coiled or equivalent spring, U, connected to the pulley at one end and to the bars V at the other end by a button, or by a coiled spring on the axis of pulley O. This spring distends when the pulley is turned in one direction, and as soon as the impelling-lever is released and the setting-rope slackened the spring recoils or retracts and turns the pulley backward and takes up the slack in the rope and unwinds the chain M from the pulley N. The bars V extend from the standards next to the boxframe B in the direction shown, and have secured to their outer ends by bolts and thumb screws j one end of a frame, V, which is supported at the other end by standards X.

The frame WV has top and bottom side rails, 70, and carries an endless chain-belt, Y, formed of links large enough to hold each a ball, z, and supported at both ends by shafts ll, provided with side flanges, m, and journaled, the

one in standards X, and the other in posts n, resting upon bars V. The shaft l has a ratchet-wheel, 0, secured to one end, with which engages a pawl, 12, pivoted to the upper part, q, of a lever which is free to turn upon shaft Z, the part q of thelever being jointed to the lower part, q, and the latter part being connected with the pulley O by a pin, T, which passes through a slot, 8, in that end of the part (1. The junction of the two parts of the lever and their connections with the frame carrying the delivery-apron and the pulley O is such that in the movement of the pulley to bring the cup end of the impelling-lever opposite to the delivery-belt the lever is made to operate the pawl. so as to turn the ratchet and move the belt far enough to deliver one of the balls into the cup when brought into position to receive it. Both parts of the lever at their jointed ends are perforated, so that the points ot'juncture may be altered to conform to the number of times the setting-rope is passed around the pulley, and thus to time the movement of the delivery-apron to the movement of the impelling-lever.

It will be observed that the delivery device may be horizontal or inclining downwardly or upwardly from the impelling-arm, and the links of the chain act as partitions, so that the balls will not crowd upon one another in feeding to the arm.

The operation of the several parts will be 5 understood from the statement of their op eration made in connection with the description of their construction, and it is not considered necessary to recapitulate them. It will be observed that the impelling-lever can IO be swung in a circle as many times as may be necessary for giving the desired impetus and direction to the balls, and that the feeding of the balls is automatic and timed with precision -to the movement of the impelling-lever. The

simplicity of construction and the absolute safety of the device and its satisfactory working must all commend themselves to those persons interested in such devices, and therefore it is unnecessary to enlarge upon them here. As the balls advance toward the cup I they roll upon a plate, XV, which is hung from the top rails, 70, by pendants. The plate W is provided at its forward end with a tongue, w, projecting toward the cup, and as the balls 2 5 are successively pushed forward they roll upon said tongue, and are thereby carried into position. to drop from its end into the cup I.
