The present invention rem n generalito target throwing devices, and, in particular; to iniprovements in traps such as used intrap and skeet shooting.

In using target throwing traps and especially the trap shown and described in the copending application of Rutherford et al., Serial No.

2,432.446, issuedDecember 9, 1947; the throwing arm is secured to a carrier head and is held in cocked position by engagement of a pawl, pivotally mounted on the carrier head, with a manually actuated or spring loaded trigger. When the throwing arm is in cocked position, the mutually engaging surfaces of the pawl and trigger are under load due to the force of thetensioned An object of the invention is the provision of improved means for latching the trapthrowing arm. A further object is to provide improved trap latching means which maybe quickly and conveniently operated to release the trap and which will withstand longperiods of servicewithout exhibiting excessive wear. 2 i These andother objectspfeatures and advantages of the invention will be more particularly described in the following specification; reference bein madeto thedrawing in which: Fig. 1 is a schematic perspectiveviewwof axtarget throwing trap embodying the improvedlatching means of this invention. i

indicated generally at I2, and which constitutes a flanged beam l3 having a depending web [4 to accommodate fastening means for securing the The forwardend of the beam it terminates in a hock-shaped head which see Fig. 4:, connected by a substantially vertical web member. The flanges I5 and I6 are provided with vertically aligned bushedapertures to receive a post I1, the upper end of which projects above the upper flange I5 and constitutes an axis for the carrier head It, the latter being freely rotatable thereon. The carrier head is connected by means of a link [9 having a bevelled shoulder 19 to-the forward end of the main spring 20, the

throwing arc to rapidly decelerate the throwing arm; The throwing arm 2| is secured to the top planar surface of the carrier head it and is moved into cocked position by means of a ratchet disk and lower flanges l5 and 16 of the frame and is provided on its bottom surface and adjacent its periphery with an integral bifuncated lug 24, see Fig. 4;to which is pivoted the forward end of the Suitable ratchet teeth 26 are tially the oppositeside of the disk 23 is a depending lug ZI which isformed integrally with or otherwise secured to the underside of the disk.

The carrier headlBhas a substantially vertical radially extending web portion 28 at the outer end of whichis a boss 29. A hole extends upwardly in this boss from the underside thereof for receiving a pawl pivot pin 30 which is adapted to pivotally support apawl on the underside of j the boss 29. The pawl is adapted normally to engage a tooth of the ratchet disk 23 so that by pulling rearwardlyon the cooking bar 25 of the disk, the carrier head and throwing arm 2| will be rotated clockwise into cocked position in which position the carrier head istemporarily held against the force of the tensioned main spring by a trigger and trigger locking mechanism.

As mentioned above, in the trap of the Rutherford et a1. application the carrier is held in cocked position by engagement of a pawl with the trigger which may be operated manually or by means of a spring to release the pawl.

The description thus far has been a general one of a trapof-tlre type shown in Fig. 1. The present invention relates to an improved latching means for holding the carrier head and throwing arm in cocked position. Referring to Fig. 2, the

boss 29 of the carrier head I8 is shown provided with a lateral extension 32 having "at "its outer end an integral depending'lug 33 which-is asubstantially rectangular parallelepiped having -a square shoulder 34 at one end and a bevelled shoulder 35 at its opposite end. A recess 36 is provided on the inner face of the lug "a'nd c'on'stitutes a seat for one end of a pawl spring 31, the. opposite end of Which is adapted to engage in a recess '38 in theadjacent-side of a-pivoted pawl 33.

The pawl-39 has a tooth 40 depending from its forward end adapted normally to be held in engagement with'a tooth 26 of the ratchet disk 23 =-by-thef0rce of the pawl spring3'l, The opposite or-rearend'of the pawl-is tapered to form a lever arm the end of which is provided with aV- shaped-notch 43 ass-shown in Fig. 4.

The trigger -for latching and releasing the cooked carrierheadis shown at 44 and comprises anarm mounted between the upper and lower flanges of the frame by a vertically disposed pivot .pin 45 intermediate the ends of the trigger arm. A cylindrical boss 46 is shown on the uppersurfaceof the-trigger arm and slightly eccentric to horizontal plane of thera tchet 'disk'2'3 (Fig. 4)

in line with the apex of the v-shapednotch 43 of the pawl arm 42. The rear arrr lfl of the trigger spring en'circlesa second-hub 49' on the trigger and lies in a"horiz'ontal.plane beneath thera't'chet disk Hand in the path oi the diOendihg Iug'ZT.

The rear end portion of the trigger 44 'is substantially' identical to the corresponding portion ofthe trigger used in the Rutherford et a1. tra'p trigger; ;Since therpawbhas been relieved of :the

is provided with an integral Substantially U- shaped upstanding flange 56"alon'g1 its outer edge.

provided with an adjustable stop -5s. The ibr- 'wa'rdly disposed is; seer thefia'n'ge constitutes a guard which partially encircles a cylin'dricalroller 60 supported to rotate freely ohfayertic'alpln 62 secured at the forward end of -the trigger.

The operation of the improved latching" i'rieans is as follows: Assuming the carrier hea'dan'd ratchet disk are in theirnorinal positions, as

shown inFig. '2,the lug 27 of'the disk"23"wi11"be in engagement with the rear arrn49' of thet'rigger spring and tension the same suflicientlyto-rotate 4 disk 23 clockwise. Since the tooth 40 of the pawl 39 is normally held in engagement with a tooth 26 of the ratchet disk by the force of the pawl spring 31, the carrier head l8 and throwing arm 2| will be rotated clockwise. Continued rotation of the ratchet disk in this direction will eventually-carry the tapered end42 of the pawl against "the' forward arm"'48 of the trigger spring, the arm 48 engaging in the V-shaped notch 43 of the pawl. The clockwise rotation of the ratchet disk has, of course, carried the lug 21 out of engagen1entwith-the rear arm 49 of the trigger sprin and consequently the trigger 44 will be biased by the-energy'of-the-tensioned fore-arm 48 and pivoted counterclockwise bringing its forward end v into juxtaposition with the lug 33 of the carrier. Furtherclockwise rotation of the ratchet disk -and carrier head is prevented when the square shoulder 34 of the lug-'33 engages the adjustable stop 58 f the trigger. -,In this position :of the carrier Ih'ad, the be'velle'd shoulder :35 of thelug is'in engagement with the 'roller lifl of the trigger, as sli'ownin 'Fig. 3. Iriitially,'however, the load, that is to-say, the force of the tensioned main ispr'ing -TD "which hasbeen tensionedby the-clock- "wise 1 rotation of the -earrier l head, -is still carried by the .pawl39. 'Concurrently, the counterclockwise displacement of 'the-trigger-has withdrawn itsrear end from in fr-ont of the spur-53 of the pivoted trigger 'lock 34 and the latter, urged Joy the;-fqrcedf the tensionspring 55, pivots counterclockwis'e andipos'itions the curved edge 52 of the spur-in' f rontoi the curved edge 50 of the lrigger-s'o as to block the clockwise rotation of eg ste 'Ior-eIease the carrier head and throwing arm, the operator moves' thecocki-ng bar 25 forwardly so toreturn the-r-atchet disk 23 to-its original .pesitlon. its the ratchet disk begins to rotate -40. counterclockwise, the load formerly carried by the-pawl is transferred-to the *mutually engaging--surfaces of the lug 3-3 and trigger roller 60.

The carrier head then reverses its direction of rotation, and the pawl guard finger 68 lags behind the pawl sufficiently to leave the teeth of the ratchet disk uncovered, thus enabling the spring biased pawl to swing into engagement with a tooth of the disk for recocking the throwing arm.
