ALEXANDER ALTMAN, OF NEW YORK, N. Y.

WRENCH.

Application filed November 24, 1824. Serial No. 751,957.

To all whom it may concern:

Be'itv known that I, ALEXANDER ALTMAN, a citizen of the United States, and a resident of the city of New York, borough of the Bronx, in the county of Bronx and State of New York, have invented a new and Improved rench, of which the following is a full, clear, and exact description.

This invention relates to wrenches and to what may be termed a spanner wrench and has for an object to provide an improved construction which may be readily shifted to take care of different sized objects.

Another object in view is to provide an improved wrench for heads of disks used in connecting abutting pipes, the construction being such that the hole engaging pins on the wrench may be shifted to properly accommodate holes arranged at different distances while at the same time permitting the wrench to function in the usual manner.

A still further object of theinvention is to provide a spanner wrench wherein oneof the pins or jaw members is adjustable in respect to the other. i a

In the accompanying drawing- Figure 1 is a perspective view of a wrench, disclosing an embodiment of the invention.

Figure 2 is a side view of one end of the wrench shown in Figure 1, certain parts being shown in section for better illustrating the construction.

Figure 3 is a fragmentary View showing a modified form of pin and clamping screw to that shown in Figure 2.

Referring to the accompanying drawing by numerals, 1 indicates a handle which may be tapered if desired. The handle 1 merges into a body 2 which is offset at 3 so that the offset section 4- may have its lower surface 5 substantially in line with the surface 6 of the sliding collar or jaw 7. In addition, the offset portion 3 presents a shoulder 8 for limiting the movement of the jaw 7 in one direction while the pin 9 limits the movement in the opposite direction and prevents accidental loss of the jaw. A jaw, orv rather a jaw pin 10, is screwed into the section 4%.

as shown particularly in Figure 2, the jaw pin being of the proper length to engage nuts, disks and the like which'are to be screwed onto pipes or other objects. A comparatively small aperture 11 is provided in the outer end of the pin 10, said aperture being adapted to receive the end of a file or other instrument whereby the pin 10 may be readily screwed into position without injuring the outer 1 surface. The jaw 7 is slidingly mounted on body 2 .and is adapted to be clamped in, any desired position by the jaw pin 12. An aperture 13 is provided in the end of pin 12, the same functioning in a-similar manner to aperture 11. In this form of the invention, the inner threaded end of the pin 12 is fiat and presses against thebody 2 over an appreciable area.

In Figure 3, a slightly modified construc tion' is provided wherein the pin 14 is provided with a tapering inner end15 whereby the pointthereof may be embedded slightly in the body 2 and thereby produce a better gripping action. .The pin 12 is preferably of the same length as pin 10 and byreason of the offset portion3 the outer ends of both of these members are in line as well as the surfaces 5 and 6. lVhat I claim is:

1. A wrench, comprising a substantially rectangular body, a collar slidingly mounted on said body, said body being offset at one end whereby a shoulder is -presented for limiting the movement of the collar in one direction, said collar being'of a size that the contact surface thereof is in thesame plane as the contact surface of said offset so as to present two contact surfaces adapted to engage simultaneously the article to be operated, a pin mounted in said body for limiting the movement of the collar in the opposite direction, a jaw pin extending from the offset part of said body, and a second jaw pin extending from said collar, said second jaw pin being threaded and extending through part of the collaruntilit engages the body forclamping the collar indifierent positions along the body.

2. A spanner wrench, comprising a body having an offset end, a slidable jaw mounted on said body and limited in its movement in one direction by said offset end, one surface of said jaw and the operating surface of said offset end being in the same plane, a pin aw for said offset end extending from the operating face, a pin jaw extending from said first mentioned jaw and extending from the operating face thereof, said pin jaws being of the same length and said last mentioned jaw acting in addition as means for clamping the first mentioned j awin different positions along said body.

ALEXANDER ALTMAN.
