SPECIFICATION forming part of Letters Patent No. 313,804, dated March 10, 1885. Application filed March 22, 1882. Renewed August 6, 1883. (No model.) Patented in England December 7, i881, No. 5,346.

To all whoml it 11i/ay concern:

Be it known that I, JACOB E. BLooM, of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Targctfliraps, of which the following is a specificatienlI My invention relates to ,that species ol'ftraps used for throwing glass, balla clay pigeons, and other like inanimaltetargets; and it consists, primarily, in combining with the coiled spring which actuates the lever that throws the target a second spring, set revcrsely, to intercept, accompany, and take up the recoil of said lever.

It further consists in various features and details of construction, such as hereinafter described and claimed, whereby this combination is achieved in the manner which I at present deem preferable.

In the drawings, Figure lisa side elevation of a trap embodying my improvements. Fig. 2 is a plan view of the head of the trap, showingthe two springs, lever, catch, and certain accessories; and Fig.`3 is a section of the head, exposing the exterior or throwing spring and interior or recoil spring.

A represents a tripod-support for the operative parts of the trap, j and a a rack formed in an annular iiange surmounting the tripod. B is a short standard-section turni-ng in a socket or bearing formed in the head of the tripod on a common center with, the rack, and baloaded pawl or dctent hinged to the section so as to be dropped intoiany one of the interdental spaces ot' the rack, and thereby hold said section and the mechanism it carries in any desired radial adjustment. At the top of this short section is a serrated or notched knuckle engaging with a similar knuckle on the lower end of a second standard-section, C, and through theseknuckles passes a pivot-bolt, c, receiving on its screw-threaded end a thumb or lever nut, c', whereby the two sections can be'clampcd in different angular adjustments upon their connecting-pivot. A third and nal standard-section, D, is secured to the top of the second or intermediate one by similar knuckles, pivot-bolt d, and clamping-nut d', arranged, however, at substantially right angies to the former, so that by means of the and as a preferred means for its embodiment,

but are not indispensable to it.

Aside from the improvements about to bc described, they and certain other parts here inafter adverted to, and also introduced by way of illustration and preference, do not differ, essentially, from corresponding parts shown in Letters Patent No. 252,230, granted to George Ligowsky on the 10th day of January, 1882, where their construction and mode of operation will be found more fully pointed out.

Centrally from the standard-head E rises a spindle, c, which receives and serves as a bearing for the hub f of the targctlever F or throwing-arm. This lever has at its lower end a clamp, f', or other device for temporarily holding the target to be thrown, and is impelled in the throwing movement by an independent strong coiled spring, G, confined at one end in 4a socket in the standardhead, and at the other seated against said lever, such construction insuring a regular and invariable sweep of the lever around a fixed pivot instead of the comparatively uncertain sweep of the corresponding arm in the patent just referred to, which was simply a tangential prolongation of the upper end ofthe spring. As in said patent,the length of the throwis regulated by a segmentrack, H, and swiveled tensionarm l, carrying at its outer end the triplatch c', whereby the lever is held against the stress of the actuating-spring preparatory to its effective movement, although it is obvious that a straight rack or along trip-latch having several notches for the engagement of the lever will accomplish this object nearly or equally as well, or that some other expedient can be adopted to vary the tension of the spring and increase or decrease its throwing power.

If the actuatingspring alone is used,the lever l bringing up abruptly and flying back with a is brought up with a sudden and violent stop at the end ol'l its sweep, often jerking off the tongue and shattering the pigeon, and .snapshots are made at the flying fragments, to the annoyance of the marksman. To overcome this defect, l apply a second and weaker spring` K, wound reverscly to the flrst,to receive the impact of the lever. This second or recoil spring, for greater compactness, strength, and security, is placed within and concentric with the actuating1 or throwing spring, as below described; but such arrangement is for the stated economical purposes only, and does not affect in any vital manner the mechanical functions of said spring,which require solely that it shall be reverse to the other in its action, and sufiiciently weaker so as to yield with the impact of the radiallysweeping lever, and finally check it and return it to its position of rest.

ln the inst-mentioned preferred construction a collar, 7i', is formed upon the standardhead, encircling the hub ot' the throwing-lcver at sufficient distance to afford a considerable annular pocket. wThe collar rises somewhat beyond the coils of the actuating spring, to which its outer wall forms a support or core, and is advisably ilanged slightly at top, to guard the upper coil from springing over when wound up. rlhe annular pocket re ceives the .recoil or check sin'ing, which, like the actuatiiig-spring, is confined at one end to the standard-heim, and at the other presses against the lever-arm, but in this instance rcverselyto the foregoing, so as to take up its lthrust. A thimble, li', ot' hard wood or soft metal, is interposed between the lever-hub and the coils of the, inner spring. to prevent undue friction and wear, and this thimble, like thecollarwhich separates thetwo springs and shields one from interference with the other, is flanged, or has a circumferential groove at top or near to the lever-arm, to prevent escape of the upper coil oi' the adjacent spring` when it is wound up. Either or both springs may, il' desired, be made adjustable.

'lhe action is briefly as follows: The throwing lever, being in the position indicati-d oy dotted lines in Fig. 2that is, set for aclionis released by del'uessing the trip-latch or trigger in the usual lnanner, and is at once inlpelled by its powerful actuating-spring in the proper direction for the delivery of the pigeon. At a suitable point in this radial throwing movement, and at its maximum speed, hline-ets the projecting upper end of the :recoil spring, and is sufficiently checked to cause the pigeon to become disengaged and take its tangential departure in flight. This check, however, is so tempered by the yielding or winding of the spring before the lever that, although the pigeon is certainly disengaged, there is no danger of breakage either to itself or to the lever, and the latter is gradually brought to a full stop and gently returned to its position of rest, instead of violent recoil of its actuating-spring.

I claim as my invention- 1. The combination in a target-trap, of a standard header support, a throwing arm or lever pivotedl thereto, a coiled spring ar ranged to actuate /said arm in its throwing movement, and an oppositely-coiled spring arranged to meet and gradually check the lever when it is 'at about its throwing-point.

2. The combinatiorrwith the pivoted throwing-lever in a target-trap, of two concentric springs wound in opposite directions, and arranged one to actuate the lever in its throwing movement and the other to receive its'impact when it is at or near the dischargingl point and gradually check it.

3. The combination, with the pivoted th rowing-lever in a target-trap, of two concentric springs wound in opposite directions, and act# ing in the mannerset forth, and a shield or partition which separates the coils of one spring from contact with the coils ofthe other.

4. The combination, in a target-trap. of a head or support adjustable as set forth, a throwing-lever pivoted to such head and carrying at its outer end a holder for the target, an independent! coiled spring seated at one end against the head and at the other bearing against the lever, to actuate it, and a trip-latch to which the lever may be connected at varying distances fi'om its position oi" rest to give greater or less tension to the actuating- Spring.

5.l The combination, in a target-trap, of a standard head or support, a lever pivoted thereto, a collar rising t'rom theh'ead and inclosing an annular pocket around the leverpivot, an actuatingspring wound about the exterior of the collar |and urging` the lever in its throwing movement, and a recoil or check spring seated in the annular pocket and receiving the impact of the lever at about tho moment it is to discharge the target.

6. The combination, substantially as described, with the pivoted throwing-lever and with the checkispring coiled around its pivot. of the thimble placed within the coils of said spring, and flanged or grooved circumferentially ne t to the lever-arm to confine the adjacenticoil of" the spring when it is wound.

7. The combination, substantially as'described, with the piv ted throwing-lever and with the coiled actuatingspring by which it` IOO IIO

In testimony whereof I aix my signature in presence ot' tvTo iwitwiesses.
