The motor continuously rotates one gear in the epicycl-ic train-,another gear drives the cocking mechanism and still another gear operates the angle changing mechanism; The constructionis such that the gear driving the cocking mechanism isheld stationarywhile the trap is .cc cd osi i n and the s r operating the angle; changing mechanism; is held stationary during the cocking operation. The target carrier or throwing arm; is rnou nted for rotation by a shaft which hasiona its end; a' crank fastened to one end of a strongspring. The gear above eis rcdit as. d iv n the oc ns, c an rotates theshaftto tension the spring until; the crankarm: is just past dead center, beyond which ,theshaii zturne ahead of the a by the springuntil reach-ing cocked position where- 1199 th as r torm d- T e r p is main tained in cocked position by a sear controlled by ahselectrically operated trigger mechanism. When; rota on h d n gearv s op ed, rotation; of theggear operatingthe angle changing mechanism isauton atically started. This n gshei n e a ro ate k. having a eccentrically meunted linl; connected to the frame supporting the throwing arm, so that the frame andthrpwing arnarecontinuously oscillated in a substantiall-y horizontal plane while h tra 51. :so k si i nh tar et i placed on the throwing arm and is launched by action; of the spring when the switch controlling the triggen mechanism, is; turnedon. The direction taken by the target is determined by the position to which the frame has oscillated at the time thisswitch is closed. 7 V i The mechanism; permitting alternateirotation of thedriving gear and-angle changing: gear is s0; designed and constructed as to introduce a variation; in the time atwhich rotation of the angle changinggeafr is initiated after the, trap is in cocked positiom 7 This makesit impossible forthe shooter to anticipate the-position of the fran e and consequent target-launching direction. During the target la-unchingand cocking opera-1 ti'onsithe throwing arm-1 undergoes a complete 7 revolution; makingitunnecessary toareve'rseitlie' direction of motion in order to cook the trap.

, 3 An adjustment is provided for varying the eccentricity with which the link is mounted on the angle changing disk so that the angle through which the frame oscillates can be increased or decreased at will. The effective length of the link is also adjustable so that the angle through which the frame oscillates can be shifted to the right or to the left at will to compensate for the effect of a side-wind on the direction of flight of the targets. An adjustable stop for positioning targets on the throwing arm likewise permits a limited shifting of the angle over which the targets are thrown, but is provided primarily for the purpose of leveling the target flight. There is also an adjustment for varying the angle at which the plane in which the throwing arm revolves deviates from the horizontal so that the elevation of the target flight can be varied at will. A recoil snubber is utilized to minimize shock between moving parts of the trap occasioned by the spring operation of the throwing arm, thereby decreasing wear on the parts and improving the smoothness of operation.

Having indicated in the foregoing in a general way the nature and substance of this invention, there follows a more detailed description of a preferred embodiment thereof with reference to the accompanying drawing in which:

Figure 11 is a diagrammatic view illustrating the electrical control system of this embodiment, and

Figure 12 is a plan view illustrating a washer utilized in mounting the target carrier.

Referring to the drawing, Figures 1 and 2, the trap has a base I on the rear end of which is mounted an electric motor 2. A gear housing 3, which encloses the entire gear mechanism, is attached to base I by means of gear housing support 4. On frame 5, which is journaled for oscillatory movement about a vertical axis on the forward portion of housing 3, there is mounted the carrier arm support 6. The carrier arm 1, Figure 3, is mounted on shaft l5 which is journaled in the carrier arm support 6. The target carrier or throwing arm 8 having a carrier rail 9 is mounted on the carrier arm 'i by means of rubber grommets Iii, grommet bushings ll, carrier bolt l2, washer i3, nuts I4, and carrier shaft it, which is threaded at its upper end 13. The carrier shaft I5 is provided below the threaded portion with flats it which prevent'ahy rotary movement of the carrier arm I about the shaft IS, the shaft :5 being provided with shoulders i'i against which the carrier arm is held by the nut Hi. The use of the rubber grommets in mounting the target carrier ii to the carrier arm '1 provides some resilience in the mounting, the grommets tending to take some of the shock occasioned by rotation and sudden stopping of the target carrier 8 during a firing and cooking operation.

The washer I3 is designed to prevent lock nuts it from working loose as a result of the oscillatory action or the target carrier The washer l3, Figure 12, is a sheet metal stamping having perforations I300 for receiving carrier bolt i2 and end Id of shaft 55, opening i301, and ears NW2. The cars E362 are turned up against the flat sides of nuts it after they have been properly tightened. Since both bolt l2 and shaft end it pass through the washer i3, it is not free to turn about either one and the turned up ears 5302 make it impossible for nuts M to work loose. The cars I502 may be extensions within opening mm of the stamping l3, 1: so desired, instead of extensions IIOnl the ends as illustrated. i'he carrier shaft 15 is connected to the main shaft 28 having a vertical axis by a universai oint so that the elevation of the target carrier can be adjusted.

The carrier shaft in, Figures 3 and 10, passes throu h the carrier arm support 5 and at its bottom is provided with a flange l9 and a blade extension 2:: having a notch 2i forming part of the universal joint. The blade extension 20 fits into a groove 23 in a ball 22. The ball 22 is also provided with a groove 2% at right angles to groove 23. lhe main shaft 28 is similarly provided at its upper end with a blade extension 25 having notch 26 and flange 21. Blade 20 is thus free to vmove in groove 23 and blade 25 is free to move in groove 24 of the ball 22, so that upon rotation of the main shaft 28 power is transmitted through the blade 25 to the ball 22 to the blade 2e and thence to carrier shaft i5, and the main shaft 28 Will thereby rotate the carrier shaft l5 through the universal joint even though they do not have a common axis. The main shaft 28, Figure 3, extends through the bottom of the frame 5 and there is mounted on the bottom end of the shaft a crank 29. A connecting member 32 is movably connected at one end to the crank 29 by means of crank pin 3i] turning in crank pin bearing 3|. The other end of the connecting member 32 has external threads 33 which arescrewed into the end of main spring 34. A plug 35 having external threads 36 is'screwed into the other end of main spring 34 and is internally threaded to receive the adjusting screw 38. The adjusting screw 38 passes through swivel block 4!] and through a slotted opening 39 in frame 5. The adjusting scew has a T-head 41 so that it can be readily turned by hand to adjust the tension on the main spring 34. The swivel block 40 and slotted opening 39 permit lateral oscillation of the spring without actual bending of the spring. The spring 34 is a flat metal ribbon coiled edgewise, in order arrearsrm per-err a minivan heavyshrine" tobeufiiiized i-' ma11-space; p I p main shaft 2e is jammed its lower end in sleeve 4? provided with' shaft Bearings Afr an sleeve bearing, the bearin 43 being flied t'othe sreeve 42 the bearing being" fixed to t e housing nd the sleeve 42 being fixed m the" frame 5.

The sear I30 is then free to pivot on pin I33. Control switch I42, mounted on carrier arm support 6, has arm I43 bearing on bar I32.

Master switch I44, Figures 1 and 2, is mounted on gear housing support 4. Release switch I45, which is hand operated and designed to permit momentary electrical connection to fire the trap, is provided with cord I45, and plug I41 adapted to fit receptacle I48 mounted on gear housing support 4, Figure 3. Power inlet plug I49 is adapted to fit receptacle I53 mounted in gear housing support 4. One side of the power supply is connected to switch I42 and to one side of the motor 2, Figure 11. The other side of the motor 2 is connected to one side of control solenoid 89 and to one side of the master switch I44. The other side of control solenoid 83 is connected to one contact of control switch I42 which is a double throw switch. The other contact of switch I42 is connected to one side of the release switch I45. The other side of the release switch I45 is connected to release solenoid I45. The other side of the release solenoid I48 along with the other side of the master switch I44 is connected to the other side of the power supply. The master switch I44 is a double throw switch which when not connecting the power source to the motor 2, shorts the release switch I45, as illustrated in Figure 11.

A piston rod I54 of a recoil snubber, Figures 1, 2, and '1, is attached at one end to an ear or projection I5I on frame 5 by means of clevis I53 and clevis pin I52 and at the other end to piston I55 in cylinder I56. The cylinder is closed at the far end by means of a cap I51, sealing ring I55, and cap locking ring I56. At the near end the cylinder is closed by means of gland I58, gland sealing ring I53, piston rod sealing ring IBI, piston rod scraper I62, scraper retaining ring I53, seal backup ring I64, and gland locking ring I65. The cylinder is enclosed in a housing I51 provided with a filling plug I58. on ears or projections m9 on gear housing support 4 by means of trunnions I13, the cylinder housing I31 being provided with bearings I1I. Port I12 in the far end of cylinder I56 permits fluid to leave the cylinder as the piston I55 moves forward or enter the cylinder as the piston I55 moves backward. Port I13 in the near end of the cylinder permits fluid to enter the cylinder as the piston moves forward and permits fluid to leave the cylinder as the piston moves backward. Pressure equalizing port I14 tends to prevent leakage of the fluid from the cylinder between the piston rod 4 and the gland I58. Expansion chamber I15 within the housing I51 tends to minimize the effect of the external temperature on the recoil chamber system. The trunnions I15 permit the cylinder I56 and housing I61 to oscillate on a vertical axis in accordance with the movement of frame 5.

A rod I16, Figures 8 and 9, which may if desired have its surface roughened or threaded, is

mounted at its ends in projections I11 from the edge of target carrier 8. Clip members I18 and I15 have holes I83 through which rod I16 passes. Clip members I18 and I19 have right angle pro- ,iections I38 and IBI, respectively, bent in opposite directions from the planes of the clip members. The projections I33 and IN extend above the surface of the target carrier 8 and are pulled toward each other by means of a rubber band or,

The housing is mounted other tensioning member I32 which serves as a stop for positioning the target on the target carrier 8. The potential position of the target can be adjusted merely by squeezing the clip members I12 and I19 between the fingers to release the frictional or looking engagement of the edges of the holes I63 with the rod I16 and sliding the members along the rod to the desired position. Upon releasing the clip members I18 and I19, the rubber band I82 again brings the projections I and I5I closer together which causes the edges of the holes I83 to frictionally engage the rod I16.

In operation, plug I45 from the electric power line is plugged into receptacle I53, and master switch I44 is turned on. Electric motor 2 is thereby started, driving worm shaft 51, worm gear 63, and sun gear 54. Upon turning on switch I44 solenoid 83 is energized causing pawl tip 85 of pawl 83 to engage teeth 19 and hold rin gear 11 stationary. With sun gear 64 rotating and ring gear 11 held stationary, planet gears 14 are caused to revolve about sun gear 54 turning driving gear 15, cocking gear I I3 and cooking ratchet I25. Ratchet I23 engages cooking pawl I23 which turns main shaft 28. Crank 23 on the bottom of main shaft 23 stretches main spring 34 during such rotation and carrier shaft I5, carrier arm 1, and target carrier 8 are rotated until the projection on arm 1 engages the sear I30. When the sear I313 is thus engaged the movement causes bar I32 to move arm I43 of control switch I42 disconnecting control solenoid 89 from the power source and connecting release switch I45 and release solenoid I40 to the power circuit. When control solenoid 35 is cut out of the circuit by the switch I42, spring 88 acting on pawl 83 disengages pawl tip 35 from teeth 13 of ring gear 18 permitting the ring gear to turn and simultaneously brings pawl tip 34 into position to engage a notch 12 in driving gear disk 59 to stop movement of driving gear III and ratchet I23 on cooking gear I I5.

During the rotation of the main shaft 28 just prior to the time that the projection on carrier arm 1 engages sear I35, crank 29 at the bottom of main shaft 28 reaches a point past center and cooking pawl I23 reaches a position such that a cam I21 disengages the pawl I23 from the ratchet I25, and the completion of the cooking stroke bringing the projection on arm 1 into contact with sear I33 is accomplished through the action of the main spring 34. The spring I31 is under tension at all times and returns trigger I35 to normal position, blocking roller I3I, immediately upon release of switch I45 and prior to completion of the cocking cycle. When arm 1 contacts sear I35, the roller moves across the fiat end of trigger I35 and moves bar I32 to operate switch I42, and de-energize solenoid 59. At this point therefore drive gear disk 6% is held stationary by pawl tip 84 which disk 69 also holds driving ear 13, cocking gear H9, and ratchet I25 stationary, while pawl I23 is held out of engagement with ratchet I20 by cam member I21.

When the spring 88 operates to move pawl tip 84 in position to engage notch 12 on disk 59, pawl tip 85 is pushed out of engagement with teeth 13 on ring gear disk 18 thereby permitting ring gear disk 18 and ring gear 11 to turn and be driven by planet gears 14, whose studs 13 are mounted in disk 59 and no longer revolve about shaft 65. Thus, while the trap is in cocked position sun gear 64 through planet gears 14 drives ring gear 11 turning disk 18 and angle changing disk 61.

Angle changing disk 61 in rotating osciiIates frame 5 through the action of angle changing link to. The main'shait 28, cocking pawl arm 124, carrier shaft [5, carrier arm support 6 and ail parts mounted thereon, including target carrier 8, oscillate with the frame 5 through a large or small angle depending upon the position of spread adjusting screw Q8. For example, if spread adjusting screw 98 is positioned in hole 99 in angle changing disk 61, no oscillation of the frame 5 and other parts occurs due to the fact that this hole is in line with the axis of shaft 66. When screw 98 is positioned in hole M the frame osciilates through a small angle. Hoies Hif through 68 provide successively larger oscillation angles for frame 5, since they are each respectively at a greater distance from the axis of rotation of shaft 65-. with the trap is cocked position and frame SQoseiIlating a target is placed on target carrier 8 against the stop m2 and the trap is ready for firing, Figures 1, 2, 3, 4, and 8. The target is thrown merely by momentarily closing the release swit'oh M5.

When the release switch M5 is turned on, release solenoid M1! is energized pushing on arm @39- of trigger r35, further tensioning' spring [31, and movin trigger end I38 out of contact with rolier m of the sear rat.

Inasmuch as the notches 12" indrifvii'rg gear diskoa are uneveniy Spaced arot'ind its periphery; there is occasioned a greater deny some incycle of positions of the frame 5 with respect to the instant that the trap is fired, so that it is impossible for a shooter to predict the angle at which the target Will be thrown. Frame 9 does not commence its oscillation until rotation of driving gear 1c is prevented b the enga ement of pawl tip 86 with a notch 12'. When the arm 1 has engaged the sear I30 the trap is again in cocked position and after placing a; target on the target carrier 8 it may again be fired merely by turning on the switch M5 and the firing and cooking cycle again repeated as often as desired.

The master switch :44 is a double throw switch, which when turned oif, Figure 11, disconnects the motor 2' and so1enoid 89 from the circuit and shorts the switch I45 thereby energizing release solenoid Mo to fire the trap, reieasing the tension on main spring 34, and causing target carrier 8 to rotate to a position where cam l2! permits pawl I23 to engage ratchet I26. When the arm 1 leaves the sear 130, the switch Hi2 operated by spring 531 to disconnect solenoid. I40 and leave all circuits dead. Thus, when master switch I45 is again turned on, the trap will go through the cooking cycle as described hereinbef'ore. Upon turning on the master switch (44 the trap is therefore in fired position with no torque on shaft 28' due to its main spring 3'4, so that the tra is' safe to handle for the urpose of making adjustments and the like. If it is desfred to have greater or Iesser' tension on main spring 34 is accomplished merely b turning the adjusting s'cre'W so. If it is desiredto change the elevation of the target carrier" 8 this is accomplished by turning adjustment member 5:.

The exact angle at which the target is thrown ciepends upon the position to which the frame 5 and target carrier 8 have os'c'illa'itd at the instant the carrier arm 7- is freed through the ac"- tion of the trigger res. As pointed out hereinbefore the spread or angle through which the frame ft and target carrier 8 osci'ilate is determined by the position of the screw 98 in the angle changing disk o1. Ifit is desired to? have the angle through which the frame 5 and target carrier 8 osciliate displaced more to the right or displaced more to the left; this canbe accom plished by changing the position of the winoage adjustment latch let'- respect to the notches IO through {alga in fii'ik 90. Likewise, by moving the stop I82 closer to the free end of the target carrier 8*, targets tend to be thrown more to the right; Whereas by moving" t e stop r82 further away from the free end" of the target carrier 8, the target's tend to be thrown more to the left". Nor'mallythefatch tongue H19 on wind; age adjustment latch 05 will be in notch I]! so that the targets will be thrown evenly to the right and left of the front of the tra If it is desire-cl;v however; to" move the angle or spread over which the targets are thrown more to the left; latch I05 is moved so that latch tongue [0 9- is' in one off" the notches I l 3 through l f0 dpefid: izig. upo'n far to the left one wishes to shift the angle: Su'ch action. is accomplished because the link 95 is successively ma e efiect'ively shorterin moving the latch tongue I'UH' successively from notch ll i into lf'fii II'Z, llil", and 1 H1 Likewise by? movin the. latch tongue sucoessively front notch rm int'o notches I is; its n 11, and 118,. th link: 90 is made successively ionger 'and' the. angle of spread is shifted, to the right. with the maximum; shift to the right being, a'cc'ol'nplisheliby stances than others in the" engagement; of placing the latch tongue -l as" in: notch uga; The:

newt tip on with notch iiiteifrubting the windage ada'ustinent huh remaifisih fi'x'edposition within hole 94 in the angle changing link 80 except when rotated by movement of windage adjustment latch I05. Such adjustments make it possible to throw the targets over the desired angle even though there be a strong side wind, since the angle over which the targets are thrown can be adjusted to the right or the left to compensate for the effect of wind on the direction of flight of the targets.

Ihe recoil snubber acting between the frame and the gear housing support 4 serves to cushion sudden movements of the frame 5. As the frame 5 oscillates while the trap is in cocked position, the piston I55 is moved backwards and forwards within the cylinder 56 at relatively low velocity, with the fluid therein entering and leaving ports I 12 and H3 with little resistance to the movement. Any sudden movement of the frame 5, however, is resisted or cushioned due to the resistance offered by the oil or other fluid in entering or leaving Hi2 and H3. Sudden or shock movements of the frame 5 are sometimes oc casioned by action of the main spring 34 in producing a torque on frame 5, during the very short period of time when tip 85 of pawl 83 is not in engagement with teeth i9 and tip 34 is not in engagement with notches '52. Such shock may cause the target to accelerate on the target carrier 8 leaving the rail 53 and then bumping into the rail 9 again, before it leaves the carrier 8, with a subsequent breaking of the target on the carrier. The recoil snubber minimizes the effect of such shock movements of the frame and target carrier 8, preventing such breakage of targets and wear on the parts.

Thus, in accordance with this invention a novel, sturdy, efficient, and compact trap for throwing clay pigeons is provided having the advantages, among others, of being electrically operated, smooth running, and capable of continuously throwing targets at varied angles without possi bility of the shooter anticipating the direction of flight of successive targets. It is to be understood that the embodiment of the present invention as shown and described is only illustrative and that many changes may be made therein without departing from the spirit and scope of the invention.
