Description

F. 0. GLLINGS.
(N o Medel.)
WRENCH.
Patented Jan.11,1898.
eration being accomplished by reason of the form of the groove 8 in the stationary jaw 7 and the slot 10, through which the pin 11 passes, is Wider than the diameter' of said pin in order to facilitate this operation of the bar 9.
In Fig. 4 I have shown an ordinary brace or stock 20, which is provided withY the usual socket-head 21, in which is formed an angular socket 22, which is, adapted to receive the angular end 23 of the shaft or shank 5 of the Wrench, and by means of this device the Wrench may be operated in the manner of an ordinary brace-bit.
I have also shown in Fig. 5 a supplemental attachment consisting of a bar 24, which is provided at one end with a head'25, in which is formed an angular socket 26, similar to the socket 22 in the brace or stock 20, and this device may be connected With the shaft or shank 5 of the Wrench and with the brace or stock 20, so as to lengthen said shank or shaft, and said attachment is provided with two transverse angular openings 27 and 28, Which are adapted to receive the end 23 of said shank or shaft of the Wrench, and when thus used the attachment will constitute an ordinary handle, as will be readily understood.
My improved Wrench is simple in construction and o'peration and is perfectly adapted to accomplish the purpose for which it is intended, and it is apparent that changes in and modifications of the construction herein described may be made Without departing from the spirit of my invention or sacrificing its advantages.
l-Iaving fully described my invention, I claim as new and desire to secure by Letters Patent- 1.
