i TARGET TRAP.

Application ea February a, 1924. Serial no; 691,682.

This invention relates to. an automatic trap, and more particularly to a form of trap for throwing clay targets, and the like. One of the principal objects of the invention is to provide an automatic trap for throwing targets, which is constructed to automatically vary the angles at which the targets are thrown, and is at the same time so constructed that this variation, in the angles is not subject to any set succession, but is indeterminate.

Another object of the invention is to provide a mechanism of this character which is simple inconstruction, durable and accurate in operation, and independent inits angle varying of manual setting or adjustment;

Other objects and advantages of the in; vention will be apparent from the description thereof setout below when taken in connection with the accompanying drawing.

In the drawing inwhich'like characte s of reference designate like parts throughout the several views thereof, j

Fig. 1 is a vertical sectional view, with certain parts shown in elevation, of a trap embodying this invention; i

Fig. 2 is a'plan view of the base portion of the device as shown in Fig.1; i N

Fig. 3 is a plan view of the target throwing mechanism shown in Fig. 1;

Fig. 4 is a fragmentary plan'view of the target throwing mechanism with the parts in cocked position; and

Fig. 5 is a view similar to Fig. 2, but show- I ing a slightly modified form ofconstruction.

Machines have been heretofore devised for the throwing of targets such as the well known clay pigeons, and in certain of these machines an effort has been'made to provide for automatic variable setting of the mechanism so as to throw the targets at variable angles. But each of such devices heretofore known has been objectionable in that the variations in the angular positioning of the trap follow a definite sequence, so that one familiar with the mode of operation of the target trap can anticipate the direction in which the target is to be thrown. In the type of device describedherein this objec tion is overcome by so. constructing the angle varying mechanism of the 'trap' as to place it under latent-control and to introduce an indeterminate factor, so that the angle vary ing follows no definite sequence, andtherefore, may not befout guessed.

This trap consists of a base member or u.

casting 10, adapted for rigid attachment to a. suitable plank or other foundatiom'not shown, by bolts passingthrough bolt holes 11. Projecting downwardly from the base member, adjacent one end thereof, is a boss or projection 12, the boss,and the portion of the base member to which it is attached having a passage 13 therethrough. Pivotally mounted within passage 13 is the shankof the pivot 15, the upper end of which is provided with an outstanding flange which forms a disc like head 16 thereon;

Slidably mounted upon the shaft isa disc 17, which is provided with suitable slots 18, to receive the pinil9, mounted within the shaft; this construction being such that movement of the disc along the shaft ispermitted, while thetwo are constrained to rotate together. lnterposed between the disc 17 and the cooperating upper face of the base member 10 isa layer or disc 20 of frictionmaterial. Around its upper outerv edge the disc-17 is cut away as shown at 23 to receive the dog carrying plate 24:. Rotatably mounted upon the pivot 15,and interposed between the disc 17 and the head 1.6 is

a ratchet disc 25, a suitable layer of friction materialfl26 being interposed between the disc 17 and the ratchet disc 25, and'a suitable layer offriction material 2'? between the ratchet disc 25 and the head 16. These two. friction discs 26 and 27 are preferably composed of material having a high coefiicientof friction, such'as sheet asbestos of the char acter used for automobile brake lining, sheet cork orthe like and constitute what may be termed a control wheel. The layer 20 is also composed of a friction material but a material which hasa substantially lower coeflicient of friction than two friction discs 26 and 9.7,such'a material for instance as vulcanized fiber, or the like. Attachedto the outstanding portion of the dog carrier 24 is a connecting rod "30, this rod being pivotally connected to one end of the extension of the dog carrier and connected atits other end to the operating pull rod 31,.so

of the mechanism, the dog carrierwill pivot about the disc '17. 'Pivotally mounted upon the dog carrier is a dog 32, which is held by means of the spring 33, in contact with the teeth of the ratchet disc 25, so that as the dog carrier is moved in one direction it will carry the ratchet disc with it, and through the instrumentality of the several friction discs, the positive movement imparted to the ratchet wheel will be imparted to the pivot and the parts carried thereby, through the frictionand therefore yieldable-means. But reverse movement of the pivot, when the dog carrier is moved in the other direction, will be prevented, because of the frictional resistance due .to the several friction discs.

Extending upwardly from the upper face of'the base of the member 10 is a hub 35, upon which is rotatably mounted the dog carrier 36. Mounted within the hub 35 is a stud 37, upon the upper end of which is rotatably mounted the ratchet wheel 38. this wheel being of a diameter which is either greater, or less than the diameter of the ratchet member 25, and having either a greater or a less number of ratchet teeth. Connecting the dog carrier 24 to the dog carrier 36 is a connecting rod 40, which is pivotally connected at its opposite ends to the respective dog carriers. Pivotally mounted upon the dog carrier 36 is a dog 41, which is held by means of the spring 42 in engagement with the ratchet teeth upon the ratchet disc 38. This dog is so arranged that as the pull bar is pulled to move the dog carrier 24, and'through the medium of the dog 32, to thus cause rotation of the ratchet disc 25, the dog carrier 36 will, through themedium of the dog 41, cause corresponding movement of the ratchet disc 38. Mounted upon the base member 10 is a dog 43, which is also held in contact with the ratchet teeth upon the member 38 by 4 means of a spring 44. And this dog 43 is arranged to act oppositely-to dog 41, so, that while the dog 41 will cause rotation of the member 38, upon movement ofthe dog carrier 36 in one direction, the dog 43 will prevent reverse movement of the member 38 when the (log carrier is moved in the opposite direction; it being understood that the friction and drag between the several parts is sufiicient-to cause the ratchet wheel 38 to oscillateback and forth with the dog carrier 36 when the pawl or dog 43 is out of operative contact with the teeth of the wheel 38. i

. Mounted rigidly upon the head 16 is a member 50, upon which is adjustably mounted the frame of the target throwing portion of the mechanism. This member 50 is provided at one end with an extension 51, which, as shown in Fig. 2, is preferably curved, the curved portion 51 overlying the ratchet disc 38. Mounted upon the ratchet disc 38, and out of diametrical alignment,

be such as to cause each ratchet wheel to advance one, two, or any desired number of teeth upon each pull of the operating bar. Preferably the arrangement is such that during operation each of these ratchet discs will be advanced three teeth upon each full pull of the bar 31. \Vhen the mechanism is thus set up to advance the ratchet wheels three teeth on each pull, the number of teeth on each wheel should be. uneven, in addition to providing one ratchet wheel with more teeth than the other. And preferably the number of teeth on each ratchet wheel should not be evenly divisible by two or three. Because of the frictional resistance interposed the pivot shaft 15, and the member 50 carried thereby, will rotate in unison with this pivot 15. As either of the pins 52 is brought into engagement with theextension 51, however, the frictional resistance between the two will be overcome and the shaft 15 will be caused to rotate in the opposite direction, even though the other discs associated therewith should continue to rotate in the original direction.

Mountedupon the ratchet disc 25 is a cam member 55, which is arranged to contact with the extension 56, upon the dog 43, and is so constructed that as the ratchet disc 2:") is rotated this cam will, during a part of the rotation of such ratchet disc, hold the dog 43 out of contact with the teeth of the ratchet member 38. When this dog is thus held out of operative engagement, the ratchet member 38 is free to move in either direction, as the dog carrier 36 is rotated, and it will remain thus free until such time at the rotation of the ratchet member 25 carries the cam out of engagement with the dog 43 so as to permit that. dog to drop into operative engagement with the teeth on the member 38, and prevent reverse movement of that member.

Mounted upon the base 10 is an upstanding lug 57 within which is adjustably mounted a stop screw 58. This stop screw is positioned within the path of movement of the other extended end 59 of member 50 to limit movement thereof in one direction.

The frame of the target throwing mechanism consists of a casting G0. which is provided with a slot 61, within which is slidably mounted a bar 62, which is held in the slot by means of suitable keepers 63. -This frame is adjustably connected to the member 50. As shown it is pivotally connected at one end to the member 50 by means of a suitable bolt 64:, and is connected intermediate its length to the member .50 by means of a bolt 65, which is positioned within the Jarcuate slot 66, this cinstruction being such that by loosening the nut of the bolt 65 the angular elevation of the frame 60 may be varied, within the operating range of the de- The rear end of the bar62 is connected to the pull rod 31 by means of a suitable pin connection, designatedgenerally by the numeral 67. Connected to the bar 62 adjacent its front end is a projection 68, on which is mounted a roller 69. This roller is adapted to cooperate with one end of the cam 70, which mounted upon the shaft 71, and is providedat itsother end with a bolt 72. Pivotally connected to the bolt is an eye member 7 3 which is connected to one end of the main spring 74, the other end of the main spring being connected to the adjust-- ing bolt 7 5, suitable manipulation of the nut 76 giving any desired iJQDSlOIlOf the main spring. Loosely mounted upon the shaft? 1, and on top of the frame 60, is the target carrier arm 80, which, as shown in Figs. 1 and 3, is of the chute type, and: is provlded with a spaced rail 81. A rubber facing strip 81 is carried by the. rail and serves to increase the rotary motion given to the targets as they leave the arm thus/adding to their stability of flight; snugly in place, and against theframe 70, by means of a coiled spring 82, the lower end of which contacts with the pin 83 carried by the arm 80, and the upper end of which contacts with the pin 84, carried by the shaft 71.

Slidably mounted upon the frame is a spring pressed latch 85, with which is associated a spring 86. Carried by thislatch is a pin 87 which is adapted to cooperate with the trigger member. 88. This trigger member 88 is pivotally mounted, at 90, :upon

the frame 60, and is provided at its lower end with an opening 91, which receives a pin 92, mounted in the keeper 63, which pin projects through the hole and limits pivotal movement of this trigger. bar 62, at its forward end, isa projection 95, which, cooperates with the trigger memb to cause actuation thereof. 1

Pivotally mounted upon the frame 60 are two curved fingers 98, which are so positionec. that when the carrier arm is in cooked position thesefingers may be swung across the arm to hold the targets in position. Two fingers are provided so that one or both may be used according as it is desired to throw one or two targets at a time. i. i

in the operation ofthedevice-the pull rod 31 is pulled by the attendant, and carries with it the bar 62, sliding that barwithin the frame. As this barthus slides the roller (39 contacts with the cam and carries that cam with it thus rotating the shaft .71. As

This ar1n80 is held Carried by the the shaft 71rotates, the arm is correspond ingly moved to bring the latch .89, at the front end thereof into latching engagement with the latch86, the proportions of the parts he ing such that the latch will overlie the latch 89 only a short distance. The amount 31 has been advanced sufficiently to effect this cocking of the mechanism, it will occupy substantially the position shown in dotted Lines in Fig. 1. Having thus cooked the mechanism the pull bar is returned toward its original position,.to substantially the position shown in full lines in Fig. 1;

On movementof the pull rod 31, to effect this cocking movement of the carrier arm mechanism the connecting rod 30 will be correspondingly moved to rotate the dog carriers 24 and 36 together, and-these williin turn movethe ratchet Wheels 25 and 38. As the ratchet 25 rotates, the pivot 15 will, under theinfluence of the friction discs, tend to move in a clock-wise direction. The ratchet Wheel 38 is at the same time rotated to move the pins 52. When either of these pins, in their rotation, meets the extension 51, being positively driven it will overcome the friction drive of the disc, and the extension 51 will therefore be moved in a counter-clock wise direction. If during this rotation of the pivot 15 neither of pins 52 move'sinto a position to contact with the extension 51, and

interrupt its movement, then this pivot will continue to move until the extended end 59 contacts with the stop screw 58, this being the extreme. right angular positioning that may be attained, this position being indicated on Fig. 2 of the drawing by means of the dotted line marked AA. Having assumed this positio n, it will remain in this position untilsuch time as one of the pins 52 contacts with the extension 51 to rotate the pivot 15 against the action of the friction discs. After one of these pins contacts with the extension 51 it will rotate the pivot in a counter-clock-wise direction, upon each pull 7 of the operating bar, and on successive-move ment ofthe operating rod the pivot will be rotated until the frame assumes extreme left angular positioning, as shown by the dotted lines BB on Fig. 2. This extreme left angular-position is dependent upon the point at which the pins 52move out of contact with the extension 51. 1 When the cam is brought into contact with the extension 56 ofthe dog42, and raises that dog from en acteristic of the mechanism.

gagement with the teeth of the ratchet 38, the ratchet wheel 38' will oscillate back and forth, upon movement ofthe operating rod, until such time as the dog 42 again comes into contact with the teeth of that ratchet Wheel. And under such circumstances the movement .of'the pivot 15 will be unaffected by the pins 52 during such time as the cam is engaged with the extension 56. By varying the length of the cam the time of holding the dog 36 out of engagement with its cooperating ratchet may be varied as desired. The objert of this construction is to break up any rhythm of movement of the pivot 15 which would occur toa degree if'the action of the ratchet wheel 38 was not retarded or interrupted. Consequently determinable angles would be thrown. But as the ratchet wheels 25 and 38 are of differentdiameters the cam is continuously changing its relationship to the pins 52 and the'interrupting action may therefore take place when the pivot is in any position.

The angular positioning of the frame, and the carrier arm mounted thereon, and therefore the angle at which the target will be thrown is under latent control, in thatwhile the mechanism is in operation the angular setting of the frame is entirely independent of the control of the operator, and is determined automatically as an inherent char And because of the indeterminate factors that are introduced, the angular positioning follows no definite sequence whatever, and it is impossible to determine what the next angular positioning will be.

Having thus cocked the mechanism, and at the same time varied its angular positioning, by pulling upon the operating rod 31 the targets are then placed upon the carrier arm 80, rest against the rubber facing of the rail 81, and supported by the fingers 98.

The attendant then moves the pull rod rearwardly a sufiicient distance to bring the extension against the lower portion of the trigger 88. This rocks the trigger about its pivot and moves the latch 86 rearwardly to thus release the carrier arm. Actingunder the tension of the main spring 74, the carrier arm will berapidly swung in a direction opposite to the direction of the cocking movement, and the target or targets, will slide along the carrier arm under the centrifugal force and will be thrown off of the arm at considerable velocity. The length of the carrier arm is so proportioned, with respect to the velocity of this swinging movement, that the targets willtravel the entire length of the arm and will be thrown free from the arm, just as the arm reaches a position sub stantially in alignment with the frame 60.

The movement of the main shaft is stopped on the main shaft, and its inertia will carry it forward, rotating about the main shaft, until its momentum is overcome by the tension of the spring 82. As the momentum of the carrier arm is absorbed this spring 82 will be wound up, and after the carrier arm has stopped the spring will move it in the reverse direction to bring it back to its normal position.

Mounted in the lower end of the pivot 15 is a. stud 100, having a regulating nut 10]. and a spring 102. mounted thereon. The spring also bears against a plate 103, the construction being such that by varying the setting of the nut the frictional resistance of the friction discs may be varied as desired.

Only one cam is shown. But if desired a plurality of cams may be used, each of which will introduce still further unknown factors into the operation of the device.

Also, as shown in Fig. 5, the cam 55 may be entirely dispensed with, and in place therefore teeth omitted from the ratchet member 38. Preferably two teeth are omitted, as shown, the device being so arranged that the ratchet will normally be advanced three teeth upon each cocking movement of the trap. By omitting two teeth where a three toothadvance is used, it is obvious that a completelyindeterminate factor is introduced.
