SELF-FEEDING TARGET-TRAP.

SPECIFICATION forming partof Letters Patent No. 519,512, dated May 8, 1894- Application filed November 25,1893. Serial No. 491,975- (No model.)

To all whom it may concern;

Be it known that I, HERBERT W. TICHENOR, a citizen of the United States, residing at Irvington, Essex county, New Jersey, have inyented certain new and useful Improvements 1n Automatic Self-Feeding Target-Traps, fully described and represented in the followng specification and the accompanying drawlngs, forming a part of the same.

This invention relates to that class of target-traps or throwers in which an arm is retracted in/opposition to spring tension,and is released after being charged with a target; and the invention consists part1 y,in the means tor setting and releasing the arm, and partly 1n means for automatically feeding the targets to a clamp upon the arm during its retraction. 1

In the present construction the arm is pivoted upon a spindle, and a crank pin is projected from the opposite side of the spindle to connect the arm with a tension spring. The arm is arranged to make a complete rotation in the same direction about the spindle, at each actuation, the arm rotating first .about one hundred and eighty degrees in which position it is held by a catch until it is discharged. This is effectedby releasing the arm which then rotates in the same direction through the remainder of the circle. As .the arm is rotated about the spindle its movement for one half a revolution is in opposition to the tension of thespring; while the remainder of the movement is efieoted by the contraction of the spring; and the arm may thus be readily set for automatic operation, if its movement during retraction be arrested by a suitable stop just after it has passed the central position, in which the crank is almost upon its dead centerin relation to the spring.

The withdrawal of the stop permits the. tension of the spring to continue therotationof the arm in the same directionin which it was retracted, and thus extends the arm with the desired velocity to discharge'the target.

. In the present invention the spindle is connected by suitable gearing with a lever, which f1s provided'with a stop adapted to arrest the arm when it has been retracted alittle more than onehundred and eighty degrees, and the crank pin has passed its dead center. The

signal to the operator through the'shock conveyed by the cord; and he is thus enabled to set the arm for operation and to release the same forits discharge by the successive movementsof thesame cord.

The apparatus is furnished with a hopper supplied with a series of targets, and the arm is furnished with a clamp which is automatically opened as it passes beneath the hopper,

to receive one of the targets. provided with oscillating dogs which are actuated, by a connection/t0 the settling lover, The hopper is curved upwardly and laterally to relieve the oscillating dogs from the greater part of the weight in the series of targets. Y The construction will be understood by reference to the-annexed drawings, in which' Figure 1' is a side elevation, and Fig. 2 a plan of the apparatus with the throwing arm extended. Fig.3 is a plan of the magazine in section on line :12, 0c,-in Fig. 5. Fig. 4 is a view, upon the inner end, of one of the oscillating dogs with its pivot.

The throwing arm 2' is attached to the spindle and formed at its rear end with the spring controlled crank m. A settinglever q is attached to the shaft (1 and" provided with acordq to pull the same, the arm hein g rotated with the spindle duringthe first halt of its rotation by the oscillation of the toothed segment, when the setting-lever is moved in-' the direction of'the arrow q (See Fig. 2.)

The magazine is supported by a carrier rod C having its'lower end bent at right anglesto its body, such lower end and body being fitted respectively to lugs D and E. upon llllefltllle a and the ring 15.. The lugs areprovided with setscrews z, and the form of the. carrier permitsthe magazine to be adjusted: vertically and laterallyinto the required position over the clamp upon the throwing arm, to fit the latter when moved in setting the same;

The end of the arm is provided with a clamp consistingof jawsJ and J attached to a common pivot atthe end of the arm, and

provided with studs J to engage the edge of the target T. Arms j are projected in oppo site directions from the jaws, at the pivot, and two llnks k are pivoted to the said arms and to one another, and connected with a spring m. The spring m is connected with a pin upon the throwing arm and may bemade adustable by a screw and jam nuts. The jaws are held normally apart by a stop y, and a stud 1 is projected downward from the jaw J to engage a stop g upon the carrier red O. The clamp is held by the spring m, normally, 1n the position shown in Fig. 2, with the jaw J in a line with the throwing arm i; but the stop 1 is so adjusted that when the clamp as in Fig. 8, is just beneath the magazine, it arrests the motion of the jaw J (by contact with the stud 3 and draws the jaws apart into the position shown in Fig. 6 by the altered action of the links is upon the armsj.

The jaws are thus held temporarily beneath the magazine to receive the target; while the.

arm is advanced to its locked position (indicated by the dotted lines I and M) by the continued movement of the setting lever. Such continued movement actuates the link (1 and drops the lowest target from the maga-- zine upon the jaws J, J, while the studs J are suiiiciently separated to admit the same. The movement of the arm thereafte'r draws the stud g away from the stop L1 and percure the arm from flying violently backward in case the pull cord is broken by accident;

and the movement of the segment d, which is necessary to move the arm from the magazine into contact with .the lug A, brings the projection r againstthe inner side of the pawl, and disengages it from the rackteeth;

in which position it is held by the spring 8.

during the reverse movement of the setting lever. During the retraction of the setting arm the pawl e retains its engagement with the spindle 0 until the spring controlled crank on has moved past its dead center, after which the spindle and the throwing arm are entirely free to operate under. the control of the spring is; and the pinionfis free to resume its initial position, shown in Fig. 2, when the cord q is relaxed, as shown in the same figure. Such release of the pawl e is effected by the operation of the cam g; the pawl and the pinion being shown in vfull lines in the posi;

tion corresponding to that of the arm a in" Fig. 8, and the axial line of the arm being indicated'by the dotted line a in Fig. 7;

The position of the pawl e when retracted by the cam is indicated in dotted lines in Fig.

'7, which position is assumed just before the throwing arm is setin contact with the lug A.

bearin n to which the s rin it is secured.

b p D By this construction the frame may be made of the usual flat plate, ribbed at the top to secure the necessary strength, and all the parts are thus arranged in a line upon the top, and the whole device is rendered exceedingly compact and cheap to construct.

- The essential novelty in this invention consists in the combination with the pivoted throwing arm and a spring for extending the same, of a setting lever and gearing adapted to set and release the arm by successive movements of the lever.

It is immaterial whether both the movements of the lever be in the same direction, as indicated in the drawings, as it is obvious that the lug A and seat A may be disengaged by a movement in either direction of the segment to which the lug -A is attached, such movement operating in either case to slide the lug out of contact with the seat A upon thethrowing'arm.

By my invention the operator is enabled to set and discharge the throwing arm by'means of a single cord and lever and the construction and operation of the device are thus simplified.

Having thus set forth the nature of my in vention, what I claim herein is' 1. In a target thrower, the combination, with a pivoted throwing arm arranged to make a complete rotation about its pivot at each actuation, of a crank-pin with spring extending the arm, and, a setting lever and gearing adapted to set and release the throwing arm by successive movements of the setting lever,
