- UNITED STATES PATENT OFFICE.

Specification of Letters Patent.

Application filed July 9, 1906. Serial No. 325,382.

To all 1070,0111, it may concern:

Be it known that I, JONATHAN DALE, a citizen of the United States, residing at Kinston, in the county of Lenoir and State of North Carolina, have invented certain new and useful' Improvements in Grapples, of which the following is a specification.

My invention pertains to improvements in Its object is to provide for readily securlng an efiective gripping action between the grapple and the object or weight engaged or lifted and to provide for readily manipulating the grapple and to carry out these ends in a simple, cheap, and desirable manner.

Said invention consists of certain structural features or instrumentalities, substantially as hereinafter fully disclosed, and specifically pointed out by the claims.

In the accompanying drawings, illustrating the preferred embodiment of my invention, Figure 1 is'a perspective view thereof. Fig. 2 is a vertical transverse section of the same. Fig. 3 is a broken longitudinal section, taken intermediately of the lever or jaw equipped members.

In the disclosure of my invention I emplo two lever or jaw equipped members 1 1, eac

having its greater length straight, as at 2, thus conveniently serving as a handle, with one end curved or hooked, as at 3, and provided at that point with a swiveled or looselyjointed fiat part or jaw proper, 4, effective for gripping or impinging the surface of the ob ject or weight to be engaged or elevated. Swiveling or loosely connecting the jaws proper, 4, to the handled portions 3 enables the former to accommodate themselves to the object or weight, so as to squarely or effectively engage or grip it regardless of any angularity of relation between said jaws proper and said levers or handles. These jaw-equipped members or levers 1 1, which have their handled portions 2 arranged side by side and to extend one beyond the otherfor grasping, have notched or serrated upper surfaces 5, which latter also successlvely rlse slightly one beyond or above the other toward the outer ends of said levers or handled portions for wedging them in place in engagement with a sliding coupling or cufi 6, em

notched surfaces of the levers or handed.

Patented Oct. 30, 1906.

providing for the retentlon of the several parts in effective position or relation when n the jaws are engaging or gripping the object or weight.

It is noted that in practically applying the grapple the levers or handled portions thereof are slipped. or inserted into rings or links of chains depending from the hoist or block and tackle appliances of a derrick or crane, none of whic however, is disclosed herein and which it is not thought necessary.

It will be understood that the various parts may be changed as to any minor details thereof without departing from the spirit of my invention.

I claim v 1. A grapple, embracing lever or handled members having inner curved or hooked ends, to' which are swiveled or loosely con-.

notched surfaces each having an upward and outward inclination for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JONATHAN DALE.
