' 29 Claims. Cl. 124- 18) ,This invention relates totargettraps of the type for projectingplay targetsjor fpige'ons or the like into the .thrgwingltraps are positioned both on the left and on the vright of the shooting field, it is obviously desirable that the two traps requirednot be loaded and cocked throughout the game by hand since this requires the continual presence and attention of two operators. Heretofore, various lgkinds of automatic magazine-loading types er traps devised have used electric motors with a coupling mechanism such as gear reducers,sprockets, chains and clutehes to gether withja target magazine carrying one or more stacks of clay targets. Prior traps of this type are generally cumbersome largely on account. of the, gear transmission systemnecessary to transfer the powerintermittently from the" electric motor. Traps of this type .sutfer j from further disadvantages in that they have an unnecessarily complex magazine feed and are characterized by excessivemovement of the stack of targets 7 which results in too much target bre akage.

Therefore it is one of the object s of my invention to provide a target throwing trap. having a new and imtaken on line V--V of Figure 4;

Another object is to provide a target throwing trap having a compact mechanism of low inertia andutmostdependability for, efiicien'tly transmitting the power required intermittently as desired to throw the target, cock the trap," and control the holding and releasing of the target carrier or throwing arm. Astill further object of my invention is vto provide a new and improved target throwing machine adaptable for ,holding a large supply of f rangible targets with substantially complete eliminationiof target breakage. 'Another object is to provide in a target throwing trap a mechanism for delivering the targets from a magazine to a target throwing mechanism with a minimum of, movement and without excessive bodiment of the invention taken at the moment immedia'tely after a target has been thrown;

Thelapparatus of this invention may be described ,gen-

erallyas comprising a base 1, aframe 2,'a gear housing leasing mechanism the latter of which are contained in the gear housing 3. {Thetarget carrier or throwing arm 5 is mounted for rotation upon the upper end of a shaft 8 to which is imparted a rotational thrust forthrowing the target by means of themainspring 6disposed.,protectively under the mainspring housing 4.

. The cocking, holding, releasing and target, loading mechanism is a compact unit contained inand associated with the gear housing 3. The motor continuously turns one gear in the epicyclic gear train, in thevgear housing 3 while the rest of the train may be set into operation to cock the. throwing arm intermittently following each throwing operation. In accordance with this ingveiition a portion of the gear train is held stationary while the rest of it is permitted to idle during the time the trap is in cocked position. Upon actuation of the release mechanism the cocking mechanism is adaptedto transmit power from the motor throughout the entire gear train at a suitable speed reduction throughrthe main shaft 8 to the mainspring 6. The gear train rotates the main shaft 8 to tension the mainspring 6 until the mainspring crank 9 attached to the lower end of shaft 8 is beyond the out dead center after which the shaft 8 and carrier arm 5 are turned ahead some further distance without shook to the cocked position whereupon the carrier is held cooked and the gearing is again set to idle. As the target carrier proceeds to the cooked position, a targetis automatically fedvto the carrier or throwing arm 5 ready" for launching. The target is thrown when the release mechanism is actuated electrically from a remote position.

In order that the elevation at which "thetlargets are ejectedmay be controlled, "there is provided an elevation adjustment screw mounted rotatably but not slidably on frame 2 with respect to the length of the screw or crank shaft, one end of which, passes threadedly through 'a swivel'11 pivotally carried by uprights 12 integral with base 1 and the other end of which is provided with a crank handle 13.

The invention will be better understood from the following more detailed description with reference to the embodiment of the invention illustrated in the drawing. As is shown most clearly in Figures 1 and 2, the entire trap is mounted upon a base 1 which is provided with means such as holes 1.4, 15 and 16 the latter two of which are arcuately slotted for attaching the base adjustably to any suitable support and which is also provided with a pair of upright supports 12 upon which there is mounted pivotally the O-frame 2 by means of elevation pivot pin 17 which'passes through the upper part of the uprights 12. Frame 2 carries motor 7 and also the gear housing 3. Mounted on the upper arm 18 of C-frame 2 is a right magazine support 20 and a left magazine support 19 to which there is attached by suitable means a lower magazine bracket 21 and an intermediate magazine bracket 22 which in turn carry

guide rails

23, 24 and 25.

These three guide rails, including rear guide rails and 24 and the front rail 25, define the magazine space v for holding a stack of nested targets. Near their upper ends the rails are attached to an upper magazine bracket 26. Attached to the front of the gear housing 3 is the mainspring housing or apron 4 which protectively covers and also provides a mount for one end of the mainspring 6 which provides the sudden thrust of throwing power needed to project a target in desirable fashion. The other end of the mainspring 6 is attached to the mainspring crank 9 which in turn imparts a rotational thrust to the main shaft 8 passing through the gear housing 3 and journaled at its lower end in the bottom of housing 3.

4 The upper end of main shaft 8 is indirectly journaled through the hub 27 of feed cam 31 in the gear housing cover 29 from which the shaft protrudes sufiiciently to carry the escapement cam 30, the carrier or throwing arm 5 with its other components and target feed cam.- 31 all by means of a splined fitting 32 at the upper end of the shaft 8.

The target carrier of throwing arm. 5 has a carrier plate 33 and a rubber or other resilient material faced rail 34. The arm 5 is formed with an upward tilt of about 5 as an extension of the circular disc portion 35 which is provided with a hub 36 internally splined at 37 for attachment to the splined fitting 32 of the main shaft 8. At the outer end of arm 5 and supported underneath it is a carrier plate 33 which supports the target in its initial travel during the throwing operation from the moment of firing to the moment when the target leaves the arm. Although plate 33 in this embodiment is attached to arm 5, it is to be understood that plate 33 could be a separate stationary member mounted on frame 2 and of suitable arcuate length to support the target while it is propelled by the rail 34. In this embodiment described, the leading edge of the plate 33 adjacent shelf 126 in cocked position is formed with a projection 175 to prevent interference with the trailing edge of the target in throwing. Depending from the carrier arm 5 is the angularly adjustable rail 34, having the resilient leading edge 38 and which is pivotably attached at the inner end to arm 5 at the fastener 39to extend outwardly above the carrier plate 33 at least to the slot 40. Angular conrtol of the target trajectory and control of the levelness of the trajectory are attained by angular movement of the adjustable carrier rail 34 about pivot 39 to a desired position of the outer carrier rail support 41 as determined by the position of support fastener 42 in the arcuate slot 40 in the carrier plate 33. Slot 40 is of such length as to permit the rail 34 to be adjusted to an angle of lead or lag as necessary to charge to the right with a tendency to a right tilt, whereas a leading rail causes a target discharge to the left with a tendency to a left tilt. To reduce the moment of inertia, the arm 5 is cast of a light metal such as a suitable magnesium alloy or the like and the light metal carrier plate 33-, it will be noted from Figure 2 inparticular, has a number of openings or cut out sections. It is to be noted that the rail 34 is adapted to be reversibly mounted to compensate for wear.

' The main power for throwing the target with the sudden impact necessary is supplied at the lower end of the main shaft 8 by mainspring 6 the ends of which are threadedly secured to an adjustable internally threaded mainspring plug 43 at the front end and similarly to a second mainspring plug- 44 at the rear for connection to the mainspring crank 9 as shown in Figure 3. The rear mainspring plug 44 is pivoted at one end to the crank 9 by means of mainspring crank stud 45 which is rotatable in crank stud bushing 46. The other or front mainspring plug 43 threadedly receives the T-headed mainspring adjusting screw 47 which in turn passes through mainspring swivel block 48 and through a slotted opening 49 in the frame 4. Screw 47 permits adjustment of the mainspring tension. The swivel block 48 permits lateral oscillation of the mainspring 6, without bending the spring. Mainspring 6 is a closely wound flat metal ribbon coiled edgewise, in order to permit a relatively heavy spring to be utilized in a longitudinally small space or length.

The mainspring crank 9 is fixedly attached at its hub to the lower end of the main shaft 8 by means of a key 50 and a clamp screw 51. The main shaft 8, as is shown in Figure 4, extends through the bottom of the gear housing 3 and is there rotatably supported in a main shaft lower bearing 52. Mounted in the bottom of the gear housing 3 above this bushing there is a main shaft oil seal 53 disposed between the main shaft 8-and the housing 3 to prevent loss of the 'oil bath contained in the housing. Upon expenditure of the throwing power stored up in the spring 6 at the conclusion of a target throwing operat'ion, cocking power is automatically channeled from the continuously operating motor 7 through the flexible coupling 54 (Figure 2) and the worm drive shaft 55 to the epicyclic gear train in gear housing 3 by way of the worm wheel gear 56 (Figure 5).

In the gear housing 3, worm drive shaft 55 having a worm ofv sufiiciently. steep lead to avoid'self-locking, is journaled in worm shaft bushings 57 and 58 (Figure 5). The worm wheel gear 56 and also the firing ratchet 59 are mounted fixedly by means of key 60 on the hub 61 of the sun gear 62. The hub 61 in turn is rotatably mounted by means of

sun gear bushings

63 and 64 on the main shaft 8. Also located in housing 3 is the control cam 65 fixedly mounted by means of the lower splined fitting 66 on the rotatable main shaft 8. Carried on the control cam 65 are the

planet studs

67, 68 and 69. Mounted rotatably on these studs are

planet gears

70, 71 and 72. Confined between worm wheel gear 56 and control cam 65 and mounted rotatably on a shoulder of the control cam 65 is the internal ring gear 73 with the external ratchet 74. The planet gears 70, 71 and 72 are also in engagement with the sun gear 62 and the ring gear 73. Control cam 65 is provided at its lower end with a cam surface having a protuberant control portion cam surface 75 and a recessed control cam surface 76 generated by a shorter radius than that which generates the protuberant portion is provided with an operating arm 82 linked by means of correct for the effect of windage on levelness and direc the firing barstud 83 to oneend of firing bar 84 adjacent to the other end of which, resting in slotted end of guide th atchet wheel 59. 7 Extension; 174 is a surface limiting the gagement of the shoulderq85 with wheel 59 and thus deterrnines the extent of movement of bar 84.

.Pressing iagainst the other end of firing bar 84 adjacent-the stiud 83 -andtending to turn the bar 84 about stud .83 counterclockwise (Figure 5) against plunger 86,,is.,the sear plunger88 which is yieldably mounted against thesearspring 89.earri ed in an extension of the hous ing 3.. known as a. sear..plunger.=bushing v 90. Sear lplunger .88 alsofunctions through firing bar stud 83 to {-turii operating lever 82 clockwiseso as to urge sear 79 into notch 78.

lnr orderto reduce: the weight and moment of inertia f thevparts. of thetrap which turn in unison during the throwingtoperation so as to obtain the highest proportion of target throwing spring power, it will be noted (Figure ).,that the controlica'm. 65 is almost entirely hollowed outexcept for three radial ribs each of which carries one oftheplanetary gears and connects the rim. and cam.

,portionsof cam 65t'o its hub portion. To further reduce iitsiyveight, the cam 65 ,may consist ofa suitable light metallor alloy.

.. Al so mounted in housing 3. is a cocking pawl 91 the .hub. 9 2.of which is pivotally mounted on the eccentric ;lmb .93 of the hold: backpawl 94 which in turn is piv- ,.otally mounted on ,and'carried by theshaft 95. The upper end of the cockingpawl 91 is provided with a rooth .96 for. engagement with the teeth or serrations of .theexternal rachet 74 carried on the. ring gear 73. When I the tooth 96 of pawl 91 engages with the ratchet 74, the force of ring ,gear .73 on the cocking pawl 91 acting throughthe eccentric hub turns the hold back .pawl .94 clockwise into engagement. with the ratchet 74 (Figure 6 The lowerendof cocking pawl 91 carries a follower 97 for engagement with the cam surfaces 75 and 76 of ,the controLcam 65. One side of the end of hold back .pawl 94 is also adaptable for engagement with the teeth ;.,or serrations .of the ratchet 74 of the ringgear 73. Bearu'ng.againstthe back side of the cocking pawl is the cockring pawl; spring 98,. acting to thrust the cocking pawl :91 away fromthe wall of the. gear housing into or toward both the ring 73- and control cam 65. The other side gofthe end of hold back pawl 94 is formed to act as an t armature seating against a pawl holding permanent magnet 99, which is mounted on a non-magnetic member 101 carried by and extending into housing 3. Magnet ..99 is fastenedto member 101 by. means of a U-shaped ,strap 100 having limited pivotal movement toaid both polesof magnet 99 to seat on pawl 94. However, the magnet may be rigidly mounted. The structure of the cocking pawl 91 and the hold back pawl 94 is suchthat in cooperation with the gearing these members prevent undesired acceleration and the shock movement which would result after the mainspr ing crank stud 45 has passed the out deadcenter at the conclusion of the cock ing operation.

0 To permit manual operation of the trap for testing or ,thelike, gear housing 3 also contains a trigger dog 102 .pivotally mounted by means of trigger arm shaft 103 on gear housing cover 29;and adapted to be turned against the operating arm 82 of the sear member 80 (Figure 4), wwhen the handle of the trigger 105 is puled up (Figure l).' Trigger 105 mounted pivotally outside frame 2 acting through the trigger pull rod 106 and the trigger arm 107, which is acted on by compression spring 115 and is disposed above gear housing cover .29 and is attached to the upper end of trigger arm shaft 103 to the lower end of which-dog-102 it'attached, causes the dog 102 to turn counter-clockwise (Figure 5)- to press against mPQrating .a m 2 rimm ng th se mem ers-@1 ,fseanJ9counter-clockwise so as to lift sear79 out of the lnotch-'-78 in.the rim ofcontrol cam 65 (Figure 6).

Suitably secured on gear housing 3 is a cover 29 in which. hub -27 of target feed cam 31, mounted on main shaft 8, is rotatably mounted by means of an upper main bearing 08 (Figure 4). Separation of cover 29 and .cam 31 is prevented by a'feed cam collar 104 secured, on

the end. of the hub27 of cam 31 by means. of feedeam collar. pins28. Targetfeedcam 31 has a well for receivingthe hub of carrier arm 5 so as to-permita greater ,degree ofengagement, between arm 5 and main shaft 8 at the splined fitting32.

,Aspointed out hereinbefore,themagazine structure consistsofthree magazine brackets21, 22' and 26 of U-shapeand three

guiderails

23,24 and 25. Although 'the magazine structure receivesprimary support from .the magazine supports 19 and 20 to whichthe lower .bracket 21 and the. intermediate bracket 22(are attached, .further support to minimize vibration is derived through a cylindrical magazine stabilizer body 109 which is connected pivotally. but fioatably by means of a pin 110 in a large hole (Figures 1 and 3) to the hollowed out forepart. of the lower, magazine bracket 21. The magazine .stabilizer109 is rotatably connected by means of magazine. stabilizer bushing 111 to the upper end of the main shaft 8. Thestabilizer 109 rests upon the targetescapement cam 30against which it is urged by stabilizer spring 112 carried in a recess in the forepart of the lower .magazine bracket '21. Stabilizer 109 thus also serves to .cOnstrain the targetescapement cam 30, the carrier arm 5, and to someextent the target feed cam 31 all three of .whichlare in engagement with the splined fitting 32 at th upperendof main shaft 8. It is to benoted that the target feed cam 31 is already, constrained axially on main shaft.8 by means of thegear housing cover 29 with the aidtof feed cam collar 104 fixed on the end of cam hub 27 by pins 28.

.entry of a pair of resilient escapement cushions 117 and 1118. These cushions are carried between an escapement carrier base 119 and escapement carriercover plate 120 which forms a sort of cushion carriage capable of slight oscillation as permitted by the clearance between the overhanging edge 121 of escapement carrier base 119 andthe-driven arm 122 ofthe escapement lever 123 upon which the carriage is pivotally mounted about the hub 124,

Cushions

117 and 118 are thusadaptable to press against the lowermost target or against the second lowermost target of the supply stack 116, as will be explained hereinafter in connection with the operation of the trap.

Mounted on the feed shelf operating bracket 125 below themagazine is a target feed shelf 126 which coacts with the target feed arm 127 one end of which is pivoted on the gear housing cover 29 and carries rotatably intermediate the ends of arm 127 a feed cam roll 128 mounted on arm 127 by means of stud 129 and bushing 130 (Figure 4) which follows the profile of thetarget feed cam 31 and thereby controls the operation of the target feed shelf by means of feed shelf roll 161. Depending from and attached to bracket 125 are a pair of spaced feed shelf guide rods 130 and 131.which slidably engage with feed

shelf guide bushings

132 and 133 which are mounted on'and protrude from the upper surface of frame 2 at the feed shelf. Disposed about each bushing and guide rod is a feed shelf lifting spring such as sprin-

gs

134 and 135 mounted in compression between bracket 125 and frame 2. Accurate positioningof the feed shelf 126 is obtained by interposition of feed shelf shims 136 between the shelf 126 and the "bracket 125; It-is' evident that the feed shelf 126"is raised by feed shelf lifting springs 134 and 135 and is lowered by target feed cam 31 in timed relationship with the rotation of carrier arm 5.

Release of the targets'from the bottom of the stack in the magazine to shelf 126 is controlled by the escapement mechanism which comprises essentially escapement cushions 1'17 and 118, the escapement lever 123 piv- -otally mounted by means of escapement lever stud 137 counter-clockwise about stud 137 (Figures 2 and 7) underthe force of escapement tension spring 140, one end of which is connected to the end of the driven arm 122 of lever 123 while the other end of spring 140 is connected to the escapement lever spring post 141 dependently mounted on lower magazine bracket 21, thus forcing

resilient cushions

117 and 118 into engagement with the lower rim of a target at the bottom of the stack. This target and all the targets above it are thus secured against dropping by the forces exerted on the target'by cushions 117 and 118 and the rear guide rails 23 and 24. When the escapement cam roll 138 rides on the protuberant portion of the cam surface of target escapement cam 30, lever 123 acting against spring 140 has been forced clockwise as far as possible, disengaging cushions 1-17 and 118 from the stack of targets 116. In this position the stack rests upon and is supported by the target feed shelf '126.

In association with the electrical system which provides both power and control for the trap and which includes the motor 7, there is a release solenoid 87 having a plunger 86 for pushing firing pin 113 slidably carried in the firing pin guide 114 mounted in gear housing 3 to initiate the throwing operation. Solenoid 87is mounted by suitable fasteners under a solenoid housing 146 provided for convenience with a hand grip 147; and housing 146 in turn ismounted by means of

screws

148 and 149 to mainspring housing 4 so as to become in effect a part of frame 2. i

The electric wiring system of the trap may be described bestwith reference to Figure 9 for two such identical traps inasmuch as two traps are required for the game of skeet. In the drawing a second wiring system identical with the first is shown in broken lines for a second trap identical with that described herein. The wiring-system of the trap itself is all carried within the

parts

2, 3 and 4 and is connected to the three-pronged power inlet receptacle 143. As shown in the drawing one of the power lines 144 is connected to one side of the motor 7. The other side of the motor 7 is connected to'one side of the solenoid 87 and to one side of master switch 145, the other side of which is connected to the other power line 150. The operation of the motor 7 is controlled by means of master switch 145 which is ac- -cessibly mounted on the upper arm 18 of C-frame 2 (Figures 1 and 2), and which is normally closed during the period of operation of the trap. The other side of the solenoid 87 is connected to the third or control line '151. Power line 144 is connected at receptacle 143 by means of power inlet connector or plug 152 to insulated external power line 153 which leads to a source of power 154 by way of double pole fused disconnect switch 155.

dines-153 is also connected by insulated lead wire 159.

For

convenience power lines

153 and 156 and control line 157 located externally of the trap may be all contained in a single insulated cable extending from the power inlet plug 152 to the junction box 160 common to the two traps employed. In like fashion the other trap is electrically connected to the electric power source 154 and to the special skeet release switch mechanism 158. Switch mechanism 158, connected to wiring in. junction box 160 by a suitable insulated'three conductor electric cable, is adapted to operate either one or the other of the traps or both simultaneously at the will of the operator who is located remotely from the positions at which the two traps are located. It is to be noted that when master switch 145 is open, both motor'7 and release solenoid 87 are deactivated. This is a safety feature in that the arm 5 may not then be released by closing control contacts 142 of switch mechanism 158 with a possibility of injury to anyone at the trap.

With the trap in cocked position with a target emplaced upon the carrier arm plate 33 from the stack 116 in the magazine, the target is thrown by momentarily closing the electric contact 142 of the release switch 158 (Figure 9), whereupon release solenoid 87 is energized and its plunger 86 pushes firing pin 113 against the end of firing bar 84 causing firing pawl shoulder or tooth 85 to engage with and be moved to the right by ratchet wheel 59 which is continuously turned counterclockwise (Figure 5). Thus moved, firing bar 84, acting through firing bar stud 83, exerts a force on the end of operating arm or lever 82 of the sear member 80 which as a result is turned to lift the sear 79 out of notch 78 formed in the rim 77 of control cam 65 (Figures 3, 4 and 6). This releases the control cam 65, main shaft 8, target feed cam 31, throwing arm 5 and target escapement cam 30 to turn counter-clockwise in unison leaving arm 5 free to throw the target from the carrier plate 33 under the impetus of tensioned mainspring 6 acting from a point at which mainspring crank stud 45 is about 30 following out dead center. During the first part of the target throwing or firing operation, the follower 97 of the cocking pawl 91 rides the protuberant portion 75 of cam 65 holding the cocking pawl tooth 96 from clattering along the teeth of ratchet 74 of ring gear 73 which during firing also turns counter-clockwise in the same direction as arm 5, main shaft 8, and continuously turning sun gear 62 inasmuch as the control cam 65 carrying the

planetary gears

70, 71 and 72 is turning with main shaft 8 far more rapidly under the impetus of mainspring 6 than the rate at which the planetary gears are caused to turn about

planet gear studs

67, 68 and 69 under the impetus of the sun gear 6 2 driven by the motor 7.

At the beginning and for about the first 50 of the throwing operation target feed cam. 31, acting through feed cam roll 128, target feed arm 1 27, and feed bracket or shelf operating roller 161, holds the target feed shelf 126 at the lower end of its travel at which shelf 126 is in line with the carrier plate 33 of rotating arm 5. At about 50 of the turning cycle of the arm measured from the cocked position, feed cam 31 begins to permit elevation of the feed shelf 126 which at about 130 of rotation arrives at the top position which is slightly below the bottom target of the stack 116. When the arm 5 and

cams

30 and 31 arrive at about the mark of angular travel, target escapement cam 30 causes the

target escapement cushions

117 and 118 to begin opening. At the position the cushions are retracted and the escapement is fully open and permits the entire stack 116 to drop a slight distance of not more than about of an inch to upraised feed shelf 126. With the stack 116 thus supported, escapement cam 30 at about the 260 point of angular travel causes the shelf 126 and the stack 116 carried thereon to lower gradually a further distance (about of an inch) equal to slightly less than the height of the rim of one target (about 1% of an inch) so tack 116; supported.on-,shelf 126 opposite the opened escapement cushions 1117 and 118. At this p i which occurs at from about the 280 to ab outthe 300 positionof angular travel, escapement. cam 30 permits ,the

cushions

117 and 118 to close on thetarget second from,the.bottom, .a.fter which feed shelf cam 31 lowers the shelf 12 6 carrying only a single target by about .of an inch to a position in line with the carrier plate 33 to aid in supporting the target just a moment before arm arrives at the loading position below supported stack 1 16 at apoint displaced from cocked and ready-to-fire v position by about 15 of angular travel. It is to be noted that the greatest target transfer movement is a movement of but a single supported target and not the entire stack.

It is to be further notedthat feed shelf 126 in coming up to take down a, target from the stack stops just a bit short of meeting with the stack so as not to bump it, which WQ dbe likely to break one or more of the frangible targets.

Before target feed shelf 126 is lowered from its ele- Vated position, at about the'250" mark of angular travel of the arm 5, .themain shaft 8, as indicated by the position of crank stud 45, has shot beyond in dead center by about 100 and begins to oscillate back or clockwise together withcontrol cam 65. 'This sudden incipient movement of reversal causes planetary gears 70, 7-1 and 72 to tend to reverse ring gearj73 and drive it clockwise. But .since reversal of ring gear 73 is prevented by the cocking pawl91, inasmuch as at this position of the parts,

" follower 97 of the pawl has dropped opposite the receding portion 76 of control cam 65 and permits cocking pawl spring 98 to force tooth 96 of the pawl against ratchet 74 of ,gear 73, the only action of ring gear 73 is toexert a force on the cocking pawl 91 which causes a torque force on the hold back pawl 94 and brings about clockwise(Figure 6) movement of pawl 94 so that it too engages with ratchet 74 of gear-73, which under these circumstances of the mechanism is secured in stationary position. With ring gear 73 thus held stationary, rotation of the sun gear 62 causes planetary gears-70, 71 and 72 to move their

studs

67, 68 and 69 in the counter-clockwise direction carrying control cam- 65, main shaft 8 and the throwing arm-5 until mainspring crank stud 45 arrives at the out dead center at which position mainspring 6 is fully tensioned.- However at-about 15 following out deadcenter position which corresponds to about 15 of angular movementbefore throwing arm 5 arrives at the :cocked ready-to-fire position, the target carried by descending target. feed shelf 126 is picked up by carrier ured fromthe cocked position.

As soon as stud 45 passes beyond out dead center, the

- tendency of mainspring 6 in view of the stationary position of. ring gear 73, held by pawl 94, is to .causethe

planetary gears

70,71 and 72 to turn ahead rolling upon 1 the internal teeth of the stationary ring gear73 faster than -motor. 7. drives them. As a result, the 'eifort of .mainspring 6 is. to drive motor 7. which in turn effects dynamic -braking'of the main shaft 8 and the'arm 5 and the other parts carried on shaft 8. This ,feature of the mechanism .ofthis invention eliminates the shock which ordinarily would occur just prior to andat placement. of arm 5 in cocked ready-to-fire position. Such shock would disrupt .the proper positioning of the target on the carrier plate it when the control'cam 65v during cocking has been turned to allow sear-79 to fall into notch 78, arm 5 has ,arrived at thecocked or, ready-to-fire position. Here follower-97 has engaged with protuberant portion 75 of cam ;65 and has iifted pawl 91 from-ratchet .74 ofwgeary73. This ,permits gear -73 toturn clockwise again; and as a result of the change in direction, hold backpawl 94 is ejected from ratchet 74. Magnet 99 then engages with the pawl 94 andkeeps it disengaged from ratchet 74 until thenext cycle.

It is to be noted (Figure 8) that the loaded target on carrier. arm 5, just before the arm arrives in the last mentioned position, which is to say the ready-to-fire position, comes into contact with the target feed finger 162 pivotally mounted at 163 on. a depending feed finger bracket 164 carried by lower magazine bracket 21. Target feed finger 162 is yieldably held in position by spring 165 one end of which is attached to the feed finger spring post 166 mounted on bracket 164 and the other end of which is attached to one end of the target feed finger 162 which is properly positioned by bearing against feed finger stop 167 also mounted on bracket 164. Feed finger 1162 is. adapted to be turned. up out of the way when carrier arm 5 is released to project the target. Until the target however is released feed finger 162 servesto guide the single target upon plate 33 to the ready-to-throw position againsttarget stop finger 168 and target guide button 169 located fixedly on target shelf 126 (Figure 7). Stop finger 168which serves to hold the target in the readyto-throw position is pivotally mounted by means of pivot 170 on bracket 171 which in turn is mounted on the frame 2. Target stop finger 168 is yieldably held to project upwardly into position by means of spring 172 one end of which is attached to finger 168 while the other is attached to bracket 171. Proper positioning of finger 168 is assured .by a projection 173 from bracket 171'(Figure 8). It is,to be observed that when release switch 142 is closed to causecarrier arm 5 and its plate 33 and rail 34 to 'go into throwing operation, feed finger 162 moves up out of the way to clear arm 5 and stop finger 168 is turned down as carrier plate 33 passes over it. Under these circumstances the loaded target is free to commence movement on plate 33 along rail 34 and be thrown.

When the master switch 145 of the trap is open, in which condition motor 7 is stopped, the trap after firing is inoperable and throwing arm 5 is in the fired position as shown in Figures 1 and 2. In this position, mainspring crank stud a 45 is standing at the in dead center while within the gear housing 3 the control cam 65 is positioned so "as to dispose notch 78 about 150 counter-' clockwise from the cocked position shown in Figure 6. At this condition of the trap, sear 79 is resting upon the .rim 77,0f the control cam 65 out of notch 78 and at the same time follower 97 of the cocking pawl 91 is disposed beyond the trailing end of the protuberant portion at the leading or initial portion of the recessed portion 76 of the control cam 65 which permits the cocking pawl finger 96 to .rest in the ratch teeth 74 of ring gear 73 under the force of compressed cocking pawl spring 98 while the hold back pawl 94 also rests in the ratchet teeth 74 into which it had been moved during the last previous manual firing operation as the stud 45 began to move back toward in dead center. With the parts of the mechanism thus positioned, it is evident that when the, master switch of the trap is closed, the first thing that happens as-soonas the motor 7 has gone into conratchet 74 of ring gear 73. This gear 73 then goes into clockwise motion the first effect of which is to throw the hold back pawl 94 toward magnet .99 which serves as a,.detent.keeping holdback pawl 94 out of the ratchet of the idling ring gear 73.. Itis to ,be notedthat on the "first cocking stroke from the fired-position, a target is fed from the magazine just as if the arm had'previously been cocked and gone through a complete cycle.

While the hold back pawl 94 has been described with a magnetic detent, it is to be understood that the detent Y grooves with a pair of oppositely disposed detent balls.

With this alternate construction, the force of ratchet 74 on cocking pawl 91 when the momentum of the arm has been dissipated causes'the hold back pawl 94 and its lever to turn clockwise (Figure 6) and push the detent plunger into its receptacle until the detent balls engage with one of the grooves to hold pawl 94 in. Thereafter, 'with the cooking pawl 91 out of engagement with ratchet 74', the movement of ring gear 73 causes the hold back pawl 94 and its lever to turn counter-clockwise pulling the'detent rod out of its receptacle until the detent balls cammed out of the first groove fall into the second. As a modification, the plunger may be provided only with one groove, i.e. the second, to hold pawl 94 out. Alternately, the outer tip of pawl 94 may be provided with a spring loaded protruding ball engageable with an opposing arcuate surface and a depression formed in a juxtaposed extension of housing 3 so as to hold pawl 94 out when the ball falls into the depression until cammed out by the action of cooking pawl 91. In still another form, the detent may consist of a spring loaded sliding latch mounted on housing 3 and adapted to be cammed into engagement with a sloping projection on the hold back pawl 94 and to be cammed out of engagement when pawl 94 is urged into ratchet teeth 74. Other equivalent detent mechanism may be employed for the function desired.

From the foregoing description it is obvious that in accordance with this invention a new and compact electrically operated target throwing apparatus with desirable operating characteristics is provided. The apparatus of this invention has the further advantage of automatic loading of targets from a desirably large supply of them in the magazine without the frequent and constant supervision of an operator. Another advantage of the target throwing trap is that target movement both in the magazine and while in transit from the magazine to the throwing arm is gentle so as to virtually eliminate the danger of target breakage. The trap is characterized by smooth operation so as not to interfere with the proper emplacement of the target on the throwing arm. In the event that a defective target should for any reason break, the magazine and loading arrangement is such as to be self-clearing and will suffer no interference with the target feed operation. It will be noted that with 'the trap structure provided there is no need for constant adjustment and maintenance since practically all the working parts which carry the load are sealed in the oil bath of the housing and are of a sturdy and dependable mechanical nature. Nevertheless, all desirable adjustments such as that of spring tension and angles are available and easily accomplished in the trap. The trap is adapted to be most easily loaded initially while in the fired position shown in Figures 1 and 2, which is the safest, after which targets may be added to the nearly depleted supply stack at infrequent intervals as needed with complete safety and without interrupting the continued operation of the trap. Thus, it is quite apparent that the apparatus of this invention is advantageous in the art of skeet shooting and that the objects and advantages are accordingly accomplished.
