WRENCH.

Application led November 24, 1913.

To all whom t may concern:

Be it known that I, RICHARD SCOTT, a citi- Zen or" the United States, residing at Greenville, in the county of Butler and State of Alabama, have invented certain new and useful Improvements in l/Vrenches; and do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to tools, and-more especially to wrenches; and the object of the same is to produce a wrench particularly adapted for use on the nuts of bolts which pass through railway rails. As is well known, in order to secure quick work it is desired to run these nuts onto their bolts rather rapidly until they come up against their washers, after which they may be turned slowly but must be turned with more force; and conversely, in removing the nuts when they are rusted in place they must be started slowly and with considerable force, but can be run o' rather rapidly.

The object of the present invention is to facilitate this work, which object is accomplished by a specially constructed wrench hereinafter more fully described and claimed, and shown in the drawings where- 1n- Figure 1 is a transverse sectional view through a rail and its sh plates, showing one use of this improved wrench, Fig. 2 is a similar view showing another use of this wrench, and Fig. 3 is a similar view showing a third use of this wrench, while Fig. 4 is a side view of the rail and wrench with the parts as in Fig. 3, looking from the right of the last-named view. Fig. 5 is an enlarged cross section taken on the line of Fig. 4, and Fig. 6 is a similar section taken on the line 6-6 of Fig. 3.

What may be called the head l of this wrench is a ring-shaped structure whose periphery may be round or polygonal and whose aperture is made of a size and shape to fit the nut to be handled. It is quite possible that there will be several such heads with each wrench, their apertures differing in size and in the number of their faces so that they are adapted to various nuts of standard gage, but I have shown and described but one, and its aperture 2 is square. At one side of the head there is formed inte- Speccation of Letters Patent.

gral therewith a radial projection 3 which is pierced with an angular hole 4 whose aXis is parallel with that of said aperture 2, and with a transverse hole or perforation 5 standing at right angles to the length of the hole 4 just above the latter.

The numeral 6 designates a handle forked or bifurcated at its lower end as at 7 and the fork-arms pass astride the projection 3 and are pierced with alined perforations through which passes a pivot 8 which may be a pin, rivet, or boltpreferably the latter in order that it may be removed when desired. Thus is formed a wrench whose head is pivotally connected with the lower end of its handle. lVhen the nut N on the bolt B projects so far beyond the web W of the rail R, by reason of the thickness ofthe {ish-plates F or from any other cause, that access to the nut may readily be had, the use of the wrench as thus far described is as follows: The aperture 2 in the head 1 is passed over the nut N with the handle 6 standing upright and passing alongside the head of the rail R, then the handle is moved in the proper direction to loosen the nut on its bolt B; this action is repeated several times until the nut is suiiiciently loose, after which the handle is turned down on its pivot 8 without causing the aperture 2 to loosen its grip on the nut N, and when the handle stands on a line substantially parallel with the aXis of the bolt B as shown in dotted lines in Fig. l of the drawing the handle can be turned or revolved to rapidly run the nut off the bolt. To replace the nut, this operation is reversed, and it is obvious that the nut can be run rapidly onto the bolt until it comes up tight against the washer, after which the parts will be straightened out or the handle moved into the plane of the head 1, and the nut set tight in place in a manner which will be clear.

The numeral 16 designates a second or supplemental handle having its lower end laterally odset or bent as indicated at 17, then made square or angular as shown at 18, and nally reduced and threaded as indicated at 19, the angular portion standing at right angles to the length of the handle. Said angular portion is adapted to fit closely into the hole 4 in the projection 3 on the head 1, and after it is put into place it is drawn tightly therein by screwing a nut 15 onto the threaded end 19 so that a shoulder 14 which exists between the bent or body-portion of the handle and the squared portion 18, is drawn up rmly against the outer side of the head 1 in a manner well shown in Fig. 5. The upper end of this supplemental handle 16 may well carry a loop 12 which can be slipped over the upper end of the main handle 6 so that the two handles are temporarily locked together and can be manipulated as one. Whatever the use of this improved wrench where both handles are employed, it is manie festly impossible to turn the main handle down at right angles to the plane of the head; but it is also obvious that the useV of both handles gives greater strength to the tool so that in rare instances a nut may be set up extremely tight or may be loosened if it has rusted so tightly in place that it is beyond the power of an ordinary wrench to move.

In track work along a railway the lloreman of a gang will often ind conditions such that a tool is demanded dii'ering'from that vdescribed under either condition above. That is to say, as seen in Fig. Q the head of the rail projects so far beyond the nut vll that a handle ywhich extends straight from the head cannot be used. At this time the pin or bolt 8 will be withdrawn and the handle 6 disconnected from the head 1, after which the handle 16 will be attached thereto in the manner described above and its lateral offset or bend 17 passed around the head of the rail so that the nut can be started out of place or screwed firmly into place, according to the work being done. With a gang of men having several wrenches, one of the wrenches could be arranged in this way and the man having that wrench could be utilized to loosen the nuts if they were being removed or set them up tight if that were his job; whilek the remainder of the gang could be using my improved wrenches with the parts differently disposed, according to the work they had to do. Thus it will be seen that this wrench having a singlehead and two handles is capable of use on the nuts under a variety of circumstances, and-is a quick-service tool when its parts are assembled in a manner dependent upon the work to be performed. I would make it entirely of metal, and the sizes and proportions of parts are i1nmaterial. I do not wish to limit myself to the use of the wrench on railway tracks, as it is quite capable Vof employment elsewhere.

lVliat is claimed as new is:

l. The herein described wrench comprising a head having a nut-aperture and a lateral integral projection on said head pierced with an angular hole whose axis isV parallel with that of the aperture and with a transverse perforation at right angles to the axis of said hole; a handle forked at its inner end and passed astride said projection, a pin through the fork arms and .perforation; a second handle having its inner end bent aside and made angular to fit said hole, means for holding this end removably therein; and a loop loosely secured to the outer end of one handle and adapted to be thrown over the outer end of the other, for the pur pose set forth.

'2. A wrench ofthe class described comprising a head having a nut-aperture there in and provided with an integral projection, said projection being also provided with an aperture having its axis extending parallel to the axis of the first mentioned aperture, a handle member distorted at its lower end and engaged with the second mentioned aperture in said head, means for removably securing the distorted lend of said handle in the aperture of said projection, 'an additional handle member removably engaged with the aforesaid projection and designed for coperation with said rst mentioned handle as a brace therefor, and Vmeans for.

clamping the outer ends of said handle mem. bers together.

'In testimony whereof I have hereunto set my hand in presence of two subscribing wit nesses. v Y
