The wherein provision is made for removing the frame 2 is pivotally united with the base 1 stop l, device 'from the path of movement of for adjustment in a vertical plane by means r the throwing arm before the trap has been 0f a hOIiZOIllly extending bOlt 0I Pin 6, 95A sprung.y which furnishes a horizontal pivotal axis 'With/these and other objects in view which about which the frame may be adjusted to will, appear as' 'the description proceeds, the control its angular position of operation or, invention consists in the novel features of more specifically, the angular position of construction, combinations of elements and operation of the throwing arm or carrier 3. 1 00 To maintain the frame fixed in such angular positions, the web 4 is provided with an arcu-` ate slot 7, which receives a bolt 8 carried in connection with the web 5. The bolt 8 is provided at one end with a tightening nut which may be turned so as to frictionally clamp the webs 4 and 5 together and to thereby securely retain the angular operating position of the frame with respect to the horizontal. In this connection it will be understood that by adjusting the frame 2 vertically and angularly the height of the flying released target may he governed with rela- .tion to the area over which the target is projected.

Fixed for rotation within substantially vertical bearings carried by the frame 2 is a shaft 9, and to which is attached at its upper end the arm or carrier 3, so that the rotation of the shaft 9 will result in corresponding rotation on the part of the target arm or carrier. The arm or carrier comprises a crank portion 10 provided at its outer end with a depending stud or pin 11.` Further, the carrier is formed to include an aluminum casting comprising essentially a flat horizontal plate as is indicated by the numeral 12 on the drawings. The plate 12 is loosely fitted around the upper end of the shaft 9 but is secured to the crank arm 10 b Vmeans of a boltl connection 13. This connection operates in an arcuate slot so that the plate 12 may be adjusted horizontally relative to thecrank arm 10 and yet retained in fixed positionsof adjustment. One side of the plate 12 is provided with a lon itudinally extending flange 14, provided wit a friction strip ofD rubber .or the like and against which is .placed the target or targets 15. Further, the plate 12 is provided at its forward end with a headed screw 16, which is positionable in any one of a plurality of threaded o enings 17. The screw 16 provides a stop or the left angle target 15. It will be understood that the trap may throw either singles or doubles, that is to say it may project either o ne or two targets at each operation. Opposite to the flange or friction strip 14 is a longitudinally extending rib 18, which serves to coniine the target in the inner part of the arm and to cause it to travel along the strip 14 1n response to centrifugal force when the arm'or carrier is released. By thus engaging with the friction strip 14 each target 1s given a rapid whirling or rotary motion when released from the arm 3Vthereby stabilizing its sailing motion and procuring greater distance of flight.

The outer portion of the carrier co-operates with a movable stop 19. This stop is in the form of a knob carried by the outer end of an arm 20, which is pivoted as at 21 on the frame 2. This arm carries an offset stud 22 which engages with a release lever 23 pivotally mounted as at 24 on the frame 2. The

upper end of the lever 23 engages with the pin or stud 11 to confine the carrier 3 in a set position preparatory to the projection of a target. Vhen the release lever 23 is oscillating, as will be hereinafter set forth, to clear the pin or stud 11, to permit of the rotation of thel carrier, the stud 22 is engaged to rock the arm 2O about its pivot 21, which draws the sto 19 downwardly out of the path of swinging movement of the carrier. It will thus be seen that the carrier is provided with both stationary and movable stops for confining the targets in the proper initial positions on the throwing arm. A light spring 25 co-operates with the stop arm 20 for the purpose of normally maintaining the latter in an elevated position. By reference t0 Figure l it will be seen that normally the movable stop is situated within a recessed or cut out portion provided at the outer end ofA the plate 12.

The inner or actuating end of the trap includes a horizontally extending stud 26. Upon this stud there is pivotally mounted a pair of operating levers, the inner of which levers being designated by the numeral 27 and the outer b the numeral 28. Both of these levers are reely pivoted at their upper ends to turn about the stud 26, while the inner lever 27 is provided with an outwardl projecting lug or ear 29 which engages with one of the edges of the outer lever 28 so that when said lever is swung in a predetermined direction the inner lever will be moved in unison therewith. The outer lever 28 includes a yoke shaped lower end 30 to which is pivotally connected, as at 31, one end of a longitudinally extending operating rod 32. The

other end of this rod, as shown in Figure 9,

is pivotally connected as at 33 with the lower end of a pivoted operating post 34. This post is pivotally mounted as at 35 upon a standard or bracket 36 situated more or less remotely from trap A, and it will be seen by manually oscillating 'the post 34 about its pivot 35corresponding movement may be imparted to the outer lever 28 and in certain instances to the inner lever 27.

The inner lever 27 is provided with a laterally projecting ear 37 provided with anopening in which is slidably mounted a spring stem 38, the other end of said stem being equipped with nuts 39 which engage with one wall ofthe ear 37. The inner end of the stem 38 is connected with one end of a strong coil spring 40, arranged within the contines of the l frame 2. The forward or opposite end of this spring is connected with a collar 41 which carries a stem 42, the latter having its forward end pivotally connected with a pin or stud 43 which depends from a cam member 44, the latter being fixed to the lower end of the shaft 9, the stud 43 and member 44 together constituting a crank for rotating Said shaft. The lower end of the pin or stud 43 is threaded for the reception of a nut 45 which .operates to hold the stem 42 in its applied position.

The cam member 44 includes a hub 46 suitably fastened to the lower end of the shaft 9, and from this hub there projects a cam plate 47, the outer surface or periphery of said plate being notched as at 48 to provide teeth adapted for co-operation with a pawl 49 which is pivotally mounted as at 50 on the frame 2, and is pressed by means of a spring 51 so that the outer end of said pawl may cooperate normally with the-teeth 48 for the purpose of preventing reverse or return movement of the carrier from its set course of rotation. The upper surface of the plate 47 is provided with a pin or stud 52 which engages normally with the curvedfend of a pivoted locking bar 53. This bar .has its opposite end provided with an eye whichis pi'votally mounted in connection witha-horizontal pin 54 formed with the inner leveri`27. The

ar 53, as shown in Figure 6, is received within a guide bracket 55 carried by the frame 2.

This bracket includes an opening 56 through A which the bar 53 extends, the lowerA wall of said opening being inclined as indicated and the rear portion of this inclined wall provides a shoulder 57. This shou'lderis adapted to engage with teeth 58 and 58a formed -upon the under surface of the bar 53. and

said bar is normally forced downwardly to insure this engagement by a light spring 59. The tooth 58 is engaged with the shoulder, 57 when single targets are projected and the j tooth 588L with said shoulder when double targets are used. l

In the operation of the trapv the target or targetsare placed on the carrier or arm 3, as indicated in Figure l, while the carrier or throwing arm is retained in the normal position indicated. Tension is then applied to the main spring 40 by rocking the post 34 in a forward direction, which results in rocking the outer'lever 28 rearwardly so that it moves the inner lever 27 in unison therewithby reason of the lug or ear 29. Since the inner lever is connected with the c'oil spring 40, and since the cam member 44 is normally held against rotation, it follows that the spring 40 will be stretched or placed under required tension by the rocking of the post 34. This rocking movement of the post is arrested by an adjustable stop screw 60 carried'by the post standard 36. When the spring 40 is being placed under proper tension the rocking movement of the inner lever 27 results in drawing the bar 53 rearwardly so that tooth 58 for single targets or 58 for double targetswill be engaged with the stationary locking shoulder 57, thereby retaining the spring under requisite ,tension for service required. 'It will be `apparent that' sharp crank arm 10 of said shaft is in engagement the'ou-ter lever 28 independently of the inner .lever 27. This forward movement of the outer lever brings the latterinto contact with one end of a spring pressed rod 62, which is ,slidably carried by the up er part of the frame 2. The forward end o the rod 62 is connected with the lower end of the pivoted release lever 23, so thatwhen the post 34'contacts with the resilient --stop idevice 61 movement will then be imparted to the lever 23 so that continued forward movetrap is sprung or releasedl ment of, the post, against the resistance of the device 61, will swing the lever 23 to a releasing position with respect to the pin 11 of crank 10` and against the stud 22 ofthe stop arm 20. This results in the lowering of the movable stop 19 and the release of the target carrying arm 3,

ermitting uence ofthe main spring 40 which is econnected in an oi center position to the cam member v44. The construction provides for the full rotation of the target, carrier or arm through .a circle of 360 degrees, producing the releaseand projection of the targets in the manner described. When the carrier begins its rotation following release it will be observed that the pin or stud 52 carried by the cam plate 47 is out of `engagement with the retracted locking bar 53, since'the teeth ofythis bar are in engagement with the shoulder 57 on the bracket 55. However,

after some rotationon the partof the cam the ltail 63 of v member and 'the target arm, the cam member reaches under and contacts with the forward end of the bar 53. The

ta il 63 is formed to include a hump or elevator stud 52 immediately before the target.

or carrier arm reaches its full position of rotation. The engagement of the stud or pin 52- with the forwardend of the releasedl locking bar permits the spring 4() to function as a. check device or cushion to arrest gradually, and without injury to the mechanisrn of the trap, the swinging movement f the arm 3 which, in operation, travels at the latter to respond to the inbv the spring pressed pawl 49 which engages with the teeth.' of the cam plate. y

In View of the foregoing it will be seen that `the presentinvention provides a target trap of relatively simple construction,'consisting of but few and readily operated and accessible parts, whichare not likely to become out of order or to occasion repair. The target trap may be readily operated from a more or less remote position by the manual oscillation of the operating post 34 which, of course,

mayF be very conveniently accomplished. It will be observed that the arm or carrier moves through a full circle of movement without being released and does not have the oscillatory back and forth motion which has heretofore been employed in connection with arms of this character. The single main spring serves for the purpose of rotating the carrier primarily and secondarily to provide a resilient means for absorbing the shock incident to the stopping of the movement of the throwing arm. This provides a trap wherein vibration and undue wear are eliminated and moreover a trap is presented wherein the parts function positively in proper correlated order. The friction strip 14 engages with the peripheral edge portions of the targets while the latter are on the carrier, and since the latter swings at high speeds following release, the targets are given a rapid whirling motion by reason of their contact with said strip when being throwncentrifugally from the'carrier. The carrier rotates `for substantially three-quarters of a full circle, or more, before its motion is gradually checked by contact with the locking bar or, stated in other words, during the time while the targets are on the carrier the latter is revolving'freely and Without obstruction in any manner so that high rotative speeds of the carrier are obtained to provide for improved projection of the targets. When it is desired to project double targets it is merely necessary to engage the tooth 581 with the shoulder 57, which can be accomplished from the operating post by adjusting the screw 60 so that the bottom of the post 34 will contact therewith when the notch 58L registers with Vthe shoulder 57, thereby to impart the necesing nuts, springs and other threaded devices through slowly executed operations to procure the desired tension on the operating spring. Y

In operation, the throwing arm will ordinarily rotate somewhat in excess of 360 before its rotation is checked by the tension of the spring 40. This rotation in excesss of j arm 28 is moved rearwardly to tension the spring 40. In the event that the pawl does not engage this `first notch, it can en age the second notch; and in either case, tie pawl prevents the throwing arm and associated y mechanism from being subjected `to injurious jarring by excessive rebound.

While I have described what I consider to be the preferred form of the invention, nevertheless it will be understood that various changes may be made therein from time to time in accordance with the expediency of practice, and I therefore do not limit myself `to the precise structure or arrangements in combinations above set forth, but reserve the right to employ such modications that may be said to fall fairly within the scope ofthe above disclosure and following claims.
