IMPROVEMENT H\ l SPANNER-WRENCHE'S.
Specification forming part of Letters Patent No. 178,084, dated March 30, 1876; application filed January 15, 1876.
' which the following is a specification:
The figure represents my improved wrench as applied to a nut.
Similar letters of reference indicate corresponding parts.
The object of this invention is tofurnish an improved wrench'that will fit any sized spanner-nut, and which shall be simple in construction, convenient in use, and at the same time of great power and strength.
The invention consists in providing a nutwrench with two equal arms, of which the rigid one has a pushing-point slightly curved, while the pivoted arm has a drag-hook on its end.
A is the handle of the wrench, the forward part of which is curved outward and forward, and is pointed to form the rigid jaw B, the said jaw and handle being thus formed in one piece. 0 is the movable jaw, upon the outer end of which is, formed a hook, and its inner end is inserted and pivoted in a socket or eye formed in the angle at the intersection of the jaw B and handle A, as shown in the figure. [11 forming the wrench the handle A and jaw B are forged in one solid piece, and an eye or socket is punched in itto receive the loose jaw G, which is then formed and pivoted in the said eye or socket. convenient and effective instrument is produced, and one having great strength and power.
I am aware that it is not new to make a wrench with a long curved pivoted jaw, having an inside seat for one side of nut, and with a short stud to bear against the nuts opposite side; but
What I claim is- A single-handed nut-wrench, having two equal arms, one of which is rigidly attached to the handle and the other pivoted thereto, the rigid one provided with pushingpoint,
and the pivoted one-with a drag-hook on its end, substantially A. FRANK SKINNER.
