Specification of Letters Patent.

. A plication filed November 2, 1806. Serial No. 285,578.

To all whom it "tag concern:

.Be it known that LEDWARD Y. Moonn, a

citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of cable and furnish means for graspingand holding the load. It is especially designed for use with an ammunition-hoist, bein' so formed that it may conveniently grasp a s ell as it lies in its case and securely hold it The grappling-arms are swiveled' to the supporting-block, which allows the load to be turned as desired. The arms are so formed that the weight of the load prevents them from prematurely releasing the load, while a clam is provided to prevent-the load shifting endw'ise. These features are hereinafter more ,fully described, and summarized in the claims.

In the drawings, Figure 1 is a pers ective view of m grap le su ported by 9. ca lo and showing t e 10a in p ace. Fig. 2,is an end view of a ple. Fig.3 isacross-section arallel wit Fig. 2. Fig. 4 is a lan view. ig. 5 is a cross-section through t e swivel at right angles to Fig. 3.

Referring to the parts by letters, A represents a supporting-bar, which carries near each end a sheave B.- The; bar is formed with ends a, which project backward, so as to leave recesses in which the wheels are mounted, the wheels being journaled on ins G, extending through the ends a and t e body of thebalr. Thesup orting-cable(designatedF) passes downwar under one of the wheels B and then upward across a groove (1' in the both reaches thereof.

the inner faces 0 bar and then downward beneath the other wheel B and upward, as shown. The two ends of the cable are intended to be simultaneously elevated; but the sheave-and-groove arrangement is provided to allow the cable to shift when necessary, equalizing the strain on G and H represent the two arms of the grapple. Each'of these arms forms ap roximatel a semicylinder. The arm G is ifurby an are-shaped opening which the 6n the edges of thearm are projecting ribs h, which take into "corresponding grooves formed by the two sides 9 g of the arm a G. This allows the. arms to be telescoped one within the other, as shown in Fi or extended, asshown in Figs. 1, 3, an 4. A

bar J is secured at its ends-to the free ends of the side members 9, extending intermediately across the arm H, the other endof the arm G having the integral cross portion g*. This makes, a strong and secure construction.

The supporting-bar A is swivele'd to the intermediate arm H by means of a member K, which is shown as a sleeve mounted in the I arm H and having .a head In on its underside occupying a recess in that arm, while above the arm it is j ournaled in the supporting-bar.

Above the su(pporting-b ar isa nut L, which serves to hol the members to ether. The

' stud is internally screw-.threade and screw- .low the arms of the grapple to'pass most convenientl into this s ace and move around the shel I bevel'o the lower ends of the arms on their outer sides, as shown at g and it". When this apple is laced over the shell andone of t e arms pul ed out from the other; the grapple will passaround the shell far enou h to support it, so that the elevation of the ca le will-raise the shell.

The weight of the shell acts downwardlyand outwardly on the "curved arms, which prevents any movement of the one into the other. The load may ,then be thus, raised to any desired oint' and is easily released by simply allowing itto be sup orted on something, taking the weight off t e grapple. To prevent the shell shifting longitudina lyin the apple, the clamping-screw N is provided. The ends of the bar A are bent out of alinement, asshown, to enable the cableto pass directly over the groove (1, which is far enough at the side to be out of the way of the head of the clamping-screw' Having thus described my lIIVGDtiOII I claimw 1. A grapple comprising a pair of arcshaped arms slidably connected vand having free ends, whereby the arms may be extend-' ed toembrace more than a semicircle or telescopedto occupy substantially a semicircle,- an supporting means on the convex side of said arms.

2. A grapple comprising an arc=shaped arm having "a pair of parallel side members,-

other and having isconnecting ends adapt-.

ed to be spread thereby,.and a'supportingebar swiveled to one, of said arms near its lnner end.

, 5. In aigrapple, the combination of anarcshaped arm, a bar swiveled thereto, asecond arc-shaped. arm. bifurcated and extending onto opposite. sides of the first arm and ribs and grooves on the cooperatingedges-of said arms. 7

(LA grapple comprising a bifurcated arc- I shaped arm, a second arc-shaped arm guided in an arc in said bifurcation, a supportingbar swiveled to-said lastrmentioned arm', and equalizing-sheaves:-carried bysaid bar.

7 A grapple com rising a biturcatedarcshaped arm, a seconiarc-shaped arm-guided in an arc in said bifurcation, a supportingbar swiveled .to said last-mentionedarm and a clamping screw screwing through the swivel.

8. In a grapple,-the combination of abifurcated arm, an intermediate arm extending into the bifurcation thereof, ribsand-grooves on the cooperative edgesof said arms, a stud mounted inthe intermediate arm, a supporterases ing-bar above the intermediate arm in which said stud is also mounted, saidstud being internally screw-threaded, and a clampingscrew occupying such internal screw-thread I and adapted to project below the intermediate arm and having a head above the supporting-bar.

r 9. A grapple comprising a pair of cooperating arms, a supporting-bar swiveled thereto, an equalizing-sheave carried near each end of the bar, and a support for the flexible elevating member carried, by the bar inter- .mediate of said sheaves, said support being at one side of the swivel and the sheaves being set at an angle to allow such flexible memberto pass directly onto said support.-

. 10. A grapple,jcomprising a pair of arms adapted to telescope with reference to each other and having disconnected ends made to approach or recede from each other by reason of such telescoping, and asupporting-bar swiveled substantially on a vert cal axisto one of-said arms.

. -11. A grapple, comprising a pair of areshaped arms adapted to telescope with reference'to each other and having disconnected ends approaching or receding from each other by reason of such telescoping, and a radial clamping-screw carried by one of said arms.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
