Application July 2,1946, Serial No. 680,944

2 Claims. 1

My invention consists oi an improved multiple socket wrench and more specifically relates to a wrench having a plurality of concentric, nested sockets, of graduated sizes which are selectively engageable with a headed bolt or the like.

The principal objects of the invention are to provide a socket wrench of this type wherein any desired socket may be readily applied to the work, all sockets of smaller diameter being automatically retracted; wherein a turning force of the same moment may be applied to the wrench, regardless of the socket being used; and wherein the wrench is of simplified construction.

These, together with various ancillary objects to become later apparent as the following description proceeds, are attained by my device, one embodiment of which has been illustrated by way of example only in the accompanying drawings, wherein:

Figure l is a front elevation of the invention;

Figure 2 is a vertical section of Figure 1;

Figure 3 is a horizontal sectional view, being taken substantially upon the line 3--3 of Figure 2; and

Figure 4 is a horizontal sectional'view, taken substantially upon the line 44 of Figure 2.

Referring now more particularly to Figure 2 of of the accompanying drawings, numeral II] denotes generally my improved wrench which consists of a plurality of concentric tubular shanks, three being indicated for convenience at l2, l4 and [6, although it will be readily apparent that any desired number may be employed. These shanks may be of any desired shape, although as illustrated, they are of tubular cross section, and may extend for any convenient length.

At their lower ends, the shanks are flanged laterally to provide annular shoulders I8, 20 and 22 respectively, said shoulders having downwardly depending skirt portions 24, 26 and 28 constituting the polygonal shaped walls of sockets for engaging the headed ends of bolts or the like. It is intended that the nested sockets shall constitute a graduated series of wrench openings for engaging a series of bolts.

Axially of the socket and shank elements, is a retainer consisting of a tubular rod 38 having an enlarged, headed upper end 32 and an outwardly flanged lower end 34 for retaining the innermost socket 24 and hence the concentric sockets thereon. The head 32 is formed with a series of axially spaced, concentric annular shoulders 36, 38 aligned with each of the inner shanks l2 and M, the end of the outermost shank l6 being welded, threaded or otherwise rigidly united to the periphery of the head 32. The outer shank l6 and socket 28 together with the tube 38 constitute a retaining means for the assembly of socket members. A series of concentric springs 48, 42 are disposed between the upper ends of the aligned shanks and stepped shoulders, there being sufflcient clearance to accommodate the operative reciprocation of the inner sockets and shanks as now set forth.

As will be readily seen from Figure 2, the downward and upward movement of the sockets is limited by the distance between the flange 34 and the lower surface of flange 22. This distance is so selected as to accommodate the thickness of a standard size nut or bolt head, whereby'all the sockets of a smaller size than the headed object are able to retract into the shank of the operative socket against the resistance of their respective springs.

If for example the socket 28 is employed, the

upper surface of the nut or bolt head will cause the telescoping of sockets 26 and 24 and of shanks l4 and [2 into the outer member. When the innermost socket 24 is employed, the middle socket 26 is free to rise in the outer socket 28 to permit complete seating of the socket 24 upon the work. When the middle socket 26 is employed, it recedes until its lower edge is flush with that of socket 28, and recedes completely when socket 28 is employed; while the inner member 24 is lifted against the action of its spring 46 by the work until the latter is fully seated in the socket 26.

When engaged with the work, a wrench may be applied to the periphery of the outermost socket 28, the torque being transmitted through successive socket walls to the element in operative position. Obviously, any other means may be employed to turn the outer shank or socket and thereby the selected element. The axial bore in tube 30 provides a ready means for inserting a probe to detach a nut or bolt head which is frozen in the selected recess.

aligned with said shanks and constituting spring 10 seats, and concentric spring means interposed between said shoulders and said shanks, each of said socket portions comprising a laterally flanged member having upper and lower surfaces, the surfaces of the outer sockets being 5 4 vertically spaced to provide a predetermined vertical movement for said sockets, relative to each other, and the inner socket being nested within the outer sockets.
