To all whom it 'III/(bj/ concern.-

Be it known that I, HORACE E. Monn LL, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in renches, of which the following is a specification.

The invention relates particularly to wrenches for buggies and wagons in which special provision is necessary for enabling the Wrench to grasp the axle nut in the hub of the Wheel, and ha for its objects: to provide a wrench of this type which will hold the nut Without being in danger of turning over when the wrench is laid down; to provide a wrench in which the extended nut socket will be stiil'ened and reinforced; and finally, to provide an eil'ective and serviceable wrench of inexpensive construction. The ii'ivention is illustrated in the accompanying drawing, in whieh-- Figure 1 is a side view of the wrench;

Figure 2 is a longitudinal section through the wrench on the line (2) (2) of Figure 3 Figure 3 is a plan view of the wrench, and

Figure 4 .is a plan view of a modified form of the wrench.

In'buggy wrenches an extended socket is necessary 1n order that the nut in the recess of the hub may be engaged, and it has heretofore been common to provide the extension 3 by giving the handle a crook, but this coni structlon has been round ob ectionable tor the reason that after the nut is removed and the wrench laid down it would turn sideways,

thereby allowing the nut to fall out and be 1 come covered with dirt, and furthermore the nut cannot be placed in stable equilibrium upon a small support such as the carriage step which is usually utilized for retaining the wrench after the nut has been removed.

The objection to this wrench has been in a measure overcome by providing a heavy body portion and mounting the nut socket on an arm projecting at right angles to the body of the wrench, but this type has also been found objectionable, as it is dilticult to cast such a shape and is weak in the projecting arm, and when constructed by building up of wrought material is too expensive [or i My invention has been di ordinary use. rected to obviating the above olqectrous, and to providing a wrench which can be cast and made comparatively light, and yet which will when laid down remain in stable equilibrium where placed, and which can be supported securely on a small surface such as a carriage step.

As shown in Figures 1, 2 and 3, 5 is the handle of the wrench carrying at its end the broad extended portion 6, from which proj ects the sides of the nut socket 7. The handle may be of any pre'l erred type, but is ordinarily made in the shape indicated,-that is, slightly cylindrical For the purpose of giving strength for the least material, and for a'tlording a good support for the hand. The portion 6 is of considerable breadth and is Hat on the bottom to all'ord a stable supporting base when the wrench is laid upon its back. It will be noted that the base 6 and the underside of the handle are in line. The socket 7, as is shown, projects from and is sti'll'ened and supported by the base portion 6. It will be observed. that when the wrench is placed upon its back, carrying the nut, it will be in exceedingly stable equilibrium because of the broad base 6, and that, because of the large amount of metal at the end of the wrench which carries the nut socket, compared with the amount of metal in the handle, that it may be laid upon the support which extends only a short distance back on the handle without danger oi the handle overbalancing the socket end. It will also be seen that the wrench is one which may be l very easily and il'iexpensively produced, and i that for the amount of metal used a maxi- I mum strength is secured.

l have shown in Figure 4 a modiiied form of wrench. In this form it will be seen that the flat portion 6 is provided with a plurality of open sided sockets, and that the central portion oi the part (5 is cored out to form an additional socket 8. These additional nut i engaging portions considerably increase the i range of the wrench and add to its ellicicncy without disturbing the function olthe wrench, as heretofore dcscribml. It will be seen that in this'l orm, as in the form shown in Figures 1 2 and 3, the base portion serves to strengthen and support the portion 7, ting ol a lighter construction ol" such nut socket than would otherwise be possible. I Having thus described my invention and i illustrated its use, what I. claim as new and desire to secure. by Letters Patent, is the foli lowing:

thereby permit- 1. In combination in awrench, afiat broad i a handle lying in substantially the same base, having a central nut socket and a plu 5 plane as the base, and an upstanding nut rality of open sided nut sockets surrounding socket having its walls supported directly on the central socket, a handle lying substanthe said base inside the opensided nutsockets, tially in the same plane as the base, and an whereby the projecting walls of such upstandupstanding nut socket having its walls l0- 1 ing socket and the base mutually support and cated inside the open sided nut sockets and I brace each other. t supported directly on such base, whereby the In testimony whereof I have hereunto projecting Walls of such upstanding socket i signed my name in the presence of the two and the base mutually support and brace each i subscribed witnesses. other.

2. In combination in a wrench, a fiat broad i base portion having a plurality of open sided nut sockets arranged around the edge thereof,
