LIFTING-HANDLE.

TO ALL WHOM I'l MAY CONCERN:

Be it known that I, PURMORT BRADFORD, ot' New Haren, in thecountj' of New Haven, and State of Con izecticut, have invented a new improvement in Lifting-Handles; and I do hereby declare theV following, when taken in connection'with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of thesame, and which said drawings constitute ypart of this specification, and represent, in

Figure 1, a. front view.

Figure i7., an end view.

Figure 3, a section on line .r x.

Figure 4, a eide view of the lifter detached; and in Figure 5, a front view of the same.

My invention is designed with special reference to cotlin handles, but is equally applicable to other lifters, and consists in the peculiar manner of attaching the lifter to the socket, wherebyfthe use of rivets or projecting sockets is dispensed with, and the construction of the handle consequently cheapcned; and to enable others to construct and use Vmy improvement, I will proceed to describe the same as illustrated in the accompanying drawings. v

A A are the two sockets; B B, the lifters; C, the handle which connects the two. @he lifter B is formed, as seen in ligs. 4 and 5, with atrunnion, a, on either side at its vupper end. The socket is formedv with a vertical slot, d, (see figs. l and 2,) upon either side ofthe said slot, and upon the under side, and midway ofthe socket, I form projecting cars, c, which form a seat to receive the trunnions a, as denoted in fig. 3. The thickness of the lifter B'must be .less or no more than the width of the slot d, so that the lifter may be passed through the slot in the socket from the back side, and when the two litters are so passed through, they arel united at their lower end by the handle C. The curve of the lifter and the length of the slot d should be such that the lifter may drop to the position denoted in fig. I, and, in red fig. 3, and when raised to the position denoted in blue, g. 3, so that the lifter will strike the upper end of the slot, there forming a stop for the handle. By this arrangement the projecting ears or sockets commonly used are dispensed with, and the: face of the socket iiush or but little raised from the ornamentation surrounding it. i

I do not broadly claim securing a lifter to its socket by means of rivets or trunnions formed thereon, as such is common and well known; but having thus fully described my invention, what I do claim as new and useful, and desire to secure by Letters Patent, is-

The socket A, formed with a vertical slot, d, provided vmidway with a seat to receive the trunnion a, constructed and arranged to operate as herein described as an article of manufacture. I

PURMORT BRADFORD.
