Specification of Letters Patent.

Application mea November so, 1918. smal No. acura.

To all 'whom tmay concern.'

Be it known that I, PETER ZL STEININGER, a subject of the Government of Galicia, Austria-Hungary, residing at St. Paul, 92 Bates Ave., in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Wrenches,

' them in the usual way, the head being of which the following is a specification.

This invention relates to improvements in wrenches and more particularly to the general utility type, wherein the jaws are formed either of one piece or with adjusting means, the invention, however, being applicable only to those adjustable wrenches having no adjusting mechanism on the handle. One of the objects of the invention is to provide a wrench so constructed as to extend its usefulness Iwhereby to reduce the number of different wrenches ordinarily required for adjusting nuts disposed in varying positions.

The invention consists in the construction, combination and arrangement of parts hereinafter described and claimed.

Figure 1 is a perspective view of the wrench embodying the invention.

Fig. 2 is a side view of the wrench show- .ing it in offset position.

Fig. 3`is a side view of the wrench 'applied as a socket wrench.

Figs. 4 and 5 are plan views of the head and handle end of the wrench.

Fig. 6 is a plan view of an adjustable alligator wrench designed to b e used in connection with the invention.

Fig. 7 is a vertical sectional view on line 7-7 of Fig. l. a

Figs. 8 and 9 are plan views of links forming part of the handle.

Referring to thedrawings 1 is the head or jaw member of a wrench formed withjaws 2 separated to engage the nut A between formed on the side opposite said j aws, with a plurality of lugs 3, preferably three in number. The handle as shown comprises a plurality of comparatively thin, Hatoblong links 5 arranged on edge, end for end, forming four parallel rows and formed with semi-circular ends contacting with each other. The rst link of each row contacts with its forward end, withthehead 1. Each link has at each end an opening 6, concentric with the semicircular ends, said opening forming a journal :for thepin 7, which latter extends laterally across the handle and supports alink of each of the four rows. Exactly bridging the space 'between the.

openings 6 of adjoininglinks 5, and having.

openings registering with the'` openings in the latter are thelinks 8. The central row i Patented sept. v1e, 1919.

of links 9 are similarv in configuration to the l links` 8 but are'shown thicker in the' cross section.- ,Thevhandle end 10 is formed with I lugs '4 similar andv corresponding to those on thehead 1 and also have sernif'zircularl ends. I

Thus when the links are assembled on thepins 7 (Fig. 1)which latter are suitably headed as by riveting or otherwise (-Fig. .7)

forming a chain, thebolt 11 is inserted through the links and lugs 3 of the head member, thenuts 12 being provided to render the bolt removable so that any form of the lhead maybe conveniently( substituted..

s are shown 'to be y of diierent lengths, it isobvious that the vWhile in' Fig. 1` the lin handle may be constructed of links of uniform length asfor instance oflinks 8. When so constructed all the links would contact with each other at vtheir ends. By arranging the links in contact endwise, the

depending upon whether the opening be tween the jaws of thehead 1 is in alinement with the handle as shown in Fig. 1, or in the offset relation thereto. As shown in Fig. 3 the wrench is adapted to work ordinarily requiring a socketwrench, the handle being swingable in either direction.

lVith the exception of the center row, the links are 'all of uniform thickness and may be stamped out of sheets of metal and assembled without additional machine work. AThe bendable portion of the handle consists solely of contiguous rows of links bound together by the pivot pins.

I claim:

1. A wrench comprising ajaw having hinge lugs and a bendable handle portion pivotally connected to said lugs, said bendable handle portion consisting solely of a plurality of contiguous rows f links7 the.....p

links of one row overlapping the links of the next adjoining row, and pins piercing the overlapping portion of the links to pivotally join the latter together to form a chain for the purpose set'forth.

2. A wrench comprising a jaw member l having hinge lugs and a bendable handle portion pivotally connected to said lugs, said bendable handle portion consisting solely of a plurality of,contiguous rows of flat links, the links of each row being arranged on edge, end "for end, the links of ad3oining rows being in overlapping relation, openingsv in the overlapping portions of the` links adapted to register with the openings in the links of the adjoining row, and pins in said .registering openings to bind the rows contactingly together. r

3. A Wrench comprising a jaw member having a straight edge opposite" the jaw thereof, a plurality of spaced hinge lugs arranged in alinement on said straight edge and extending away from said jaw, a pivot pin piercing laterally all of said lugs and :'irallel with said straight edge, and a bendable handle portion consisting solely of a plurality of contiguous rows of round ended links, the links of one row overlapping the links of the neXt adjacent row, pivot pins piercing the overlapping portions of all the links to contactingly bind the rows together the end links of each alternate row pierced by said lirst named pivot pin and contacting with one of its ends said straight edge for the purpose set forth.

4. wrench comprising a jaw member having hinge lugs, and a bendablehandle portion pivoted in said hinge lugs, said bendable portion consisting solely of links l and pivot pins connecting said links in overlapping relation and pivotally joined together in their overlapping portions as and for the purpose set forth.

In testimony whereof I in presence of a witness.

PETER Z. STEININGER.
