Specification of Letters Patent.

Patented June 12, 1906.

Application filed May 18, 1905I Serial No. 261.009.

My invention relates to improvements ingra plin devices or hooks.

IIt) gi device e eetive either for a plication interiorly or exteriorly to .the o Ject or weight lifted or actedeupon, especially as found desirable in handling certain kinds of building material as well as in general use.

Said invention consists of the detailed structural lfeatures including the combination and arrangement of the arts substantially as hereinafter fully disclbsed and partieularlynoted.

In the accom anying drawings, illustrating the preferre embodiment of my invention, Figure 1 is a perspective view thereof, and Figs. 2 and 3'are views in elevation showing the internal application and the external application of the device to the object for lifting, respectively. Fig. 4 isa modification disclosing means for adjusting the fulcrums i leg 1b has the outline substantially shown,

handling building-blocks, and so as to cause or pivots of the hook or jaw member latera ly.

In the disclosure of the invention I provide two principal hook or jaw members l, each having an upper outward deflected or .in-

clined arm l of requisite dimension and a lower portion or leg 1lD with an outward-extender lateral terminal 1C, the purpose of which will be fully apparent later. Each the same being practicaly right-lined-from its lower terminal or foot upward to a little more than half .its length, whence it is inclined inward and upward to its juncture with the arm la. The purpose of this construction, it

will be noted, is to render the device applicable for internal use, more especially in the same to impinge or bear upon the end walls of the core-opening in said blocks throughout the depth of such walls, while the lower lateral terminals or feet thereofrest below and aid to carry the weight of said blocks, as shown in Fig. 2. 'Each jawmember is coiled or looped upon itself at the conjunction of its arm and leg p ortions so as to form an eye 1d, the eyes o the two jaw or has lprimarily for its object to render the I hook members registering one with the other and. receiving a suitably-headed and nutequipped pivot-bolt 2, the latter being upset upon its nut to effectively interlock the same, thus providing for the connecting pivotally toget er of said jaw or hook membersinforming the grapple. The arms la of said jaw or hook members have connected to eye-ended terminals thereof-eye-ended links or rods', the outer eye-ended terminals of thelatter being themselves connected to ether by acommon ring 4, to which is suita ly attached the suspending and hoisting chain 5 in practical use.

As shown in Fig. 3, the grapple or device is also capable of external application, said jaw members in that case being crossed one over the other, permitting the points or free ends of their lateral extensions or feet to -be engaged with the outer surface of the object or weight t'o be raised, as well understood and as generally practiced.-

As illustrated by Fig. 4, instead of providing a single or common pivot for the hook or jaw members each has a separate pivot or fulcrum 2JL to rovide for disposing said jaw or hook mem ers laterally of the center thereof to accommodate the device or grapple to larger-sized blocks than would 'otherwise be` the case or as provided for by the above-described arrangement of parts. In

' effecting this enlargement of the grapple opposed plate members 2b, connected or couled centrally together by a nut-equipped olt 2, are provided for that purpose, having registering apertures therein near the ends of said plate members with nut-equipped pivotbolts 2d pass-ed therethrough and through the eyes 1d of the jaw or hook members 1 and secured in place by suitably manipulating the nuts upon said pivot-bolts.

I claim.-

1. A grappling device comprising two pivcted or connected-together hook or}aw members having their point of connection constituted of eyes or loops formed therewith and arranged side by side and of a pivot inserted through said eyes or loops, said members each having an arm inclined outward and upward above said point of connection and a leg hav` ing an upward and inward-inclined portion ,and a practically right-lined lower portion terminatcd.into an outward-extended horizontal portion, whereby said hook or jaw members are rendered effective either with their lower terminals presented inward toward each other or outward'a'way from each other for the urpose disclosed. 4

2. A. grapp ing device comprising two con heated-together hook or jaw members having their point of connection constituted of eyes .or loo' s formed therewith and arranged side by si e and of a pivot inserted throughv said eyes or loops, sed members each having an arm inclined outward and u ward above said point of connection and a eg having an upward and inward inclined portion and a practically right-lined lower portion terminatedjnto an outward-.extended horizontal portion, and link members effecting connec- 15 tion between the upper ends of said arms.

bIn testimony whereof I affix my signature in presence of two subscribing witnesses.
