FOLD-ABLE SOCKET- WBENCH.

Specification of Letters Patent.

Application filed April 7, 1921.. Serial 110.45%),459.

j ect to provide a device of this class which is an improvement over prior devices known and used, the same being of extreme simplicity and durability and made up of comparatively few parts including sockets of various sizes, permitting the same wrench to serve to fit nuts of various sizes, which would otherwise require the use of several wrenches.

Another object of the invention is to provide a foldable socket wrench embodying a pair of pivotally connected bars carrying various sizes of sockets as above suggested, these bars being arranged at the right angles to one another when in use, and one of them 7 having an elongated slot through which the pivot pin extends, thus enabling this bar to be adjusted toward and from the other bar to enable its socket to be fitted on nuts in places difiicult of access.

Another object of the invention is to provide a wrench of this type embodying the aforesaid bars riveted together and crossing one another at their centers, one of said bars serving as the handle when the socket on the other bar is in use, and vice versa.

Other objects and advantages of the invention will become apparent during the course of the following description:

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same:

Figure 1 is a top plan view of a socket wrench constructed in accordance with the invention showing the parts in the positions they assume when in use.

Figs. 2 and 3 are sectional views taken on the planes of the lines 2-2 and 3-3 respectively of Fig. 1.

Fig. 4 is a top plan view of decreased size showing the wrench in folded position.

Fig. 5 is a side oredge elevational view of Fig. 4.

Referring to the drawings by numerals, 1 designates a straight flat-faced metal bar whichis formed at itsopposite ends with socket 2 for reception of nuts. It maybe mentioned that the sockets, if desired, may vary in size and shape to accommodate various sizes and shapes of nuts. in addition to the bar 1, comprises a second and thinner bar 3, which, when in use, extends across the first named bar as disclosed in Figs. 1 to 8 inclusive. This bar 3 like the first named bar iscquipped with' a socket 4 and in addition is formed in immediateends with a longitudinal elongated slot 5, through which the non-circular head 6 of a connecting pin 7 passes, the latter being carried by the bar 1 and disposed intermediate the ends of the latter as shown. This construction and arrangement permits the socket 4 to be moved toward and from the bar 1 to enable it to be positioned for use The wrench Patented Sept. '13, 1921.-

in places difficult of access or in places.

which are such that the bar 1, which is then the handle, would interfere with easy and effective operation ofthe wrench. This construction also permits the bar 3 to be ,arranged in the foldable overlapping relation with respect to bar 1 as indicated in Fig. 1 to render the wrench compact. It is to be noted that the head 6 of the connecting pin 7 extends through and beyond the slot in bar 3 and to this extended end of the head, I pivot a handle or arm 8 as at 7* the latter being equipped at its inner end with a fork 9, which straddles the head 6 as shown. It is to be noted that this handle 8 is, when in use, folded against the outer face of the bar 3 and is disposed in alinement therewith. This is also the case when the wrench is folded and out of use.

In using the wrench, the bars 1 and 3 are disposed in the angular positions disclosed in Fig. 1. Assuming that one of the sockets 2 is to be engaged with a nut, it will be seen that the arm 8 and bar 3 will serve as a handle to permit the bar 1 to be rotated to screw or unscrew the nut as the case may be. On the other hand, if the socket 4 is engaged with a nut, the bar 1 will then become the handle. As before intimated, if, when the bars are in the relative angular positions shown, the bar 1 tends to interfere with easy operation of the socket 4, the bar 8 due to its adjustable connection with bar 1, can be moved to properly position and engage it with a nut in a place di'flicult in access. Due to this construction, the bar 1 does not therefore interfere with the effective and easy engagement of the socket t with a nut in such places. Should it become necessary, the bar 3 can be arranged at angular positions intermediate the one shown in Fig. 1. That is, the bar 8 need not be disposed at true right angles to the bar 1., but can be arranged at other angular positions than the one shown. When the wrench is out of use. the bars and handles can be arranged in overlapping relation as disclosed in Figs. 4. and 5, whereby the device will be rendered extremely compact for coi'ivenient packing and shipping.

Other advantages and features of the invention and construction and manner of using the same have, no doubt, become apparent from the foregoing description and:

drawings. Therefore, a more lengthy and detailed description is deemed unnecessary.

Since probably. the best results may be obtained with the construction and arrangement herein shown and described, this construction and arrangement is taken as a preferred embodiment of the invention. However, slight minor changes coming within the scope of the subjoined claim may be resorted to. V

Vb at I claim is,

A wrench oi? the type described comprising a bar having sockets formed in its opposite ends, a second socket-carrying bar formed with an elongated slot, a pivot and connecting pin passing through the center of first-named bar and through slot in the remaining bar, connecting the latter to the iloriner and permitting it to be adjusted, tolded against, or arranged at various angular positions with respect to the first bar. and a handle pivoted to the tree or extended end of said pin.

In testimony whereof I have hereuntoset my hand.

RICHARD C. SCOTT.
