Specification of Letters Patent.

I Application filed December 16, 1916. ..Serial No. 137,452. 1

To all whom it may concern.

Be it known that I, GEORGE P. SoHRnIBnR,

a citizen of the United States, residing, at

Baltimore, in the State of Maryland,.have invented certain new and useful Improve- ..ments in Tool-Sockets of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to. an improved tool socket whereby a plurality of tool maybe vention to provide a handle socket for tools which is so constructed that it will securely and rigidly hold the shank of the tool in connection with the handle against relative movement, and with a minimum of strain upon the parts of the socket.

It is also an important object of the invention to provide a device for the above purpose which is durable, serviceable and convenient in practical use, and capableof manufacture at relatively small cost.

With the. above and other objects in view, my invention consists in the novel features of construction, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which,

Figure l is a side elevation illustrating the preferred embodiment of my improved tool socket;

Fig. 2 is alongitudinal section thereof;

Fig. 3 is a perspective view of .the body portion of the socket;

Fig. 4 is a section taken on the line l4c of Fig. 2;

Fig. 5 isa similar .view of one-.of the tool members; i

Fig. .6 is a detail section of the tool receiving head which may be used in connection with the socket, having means to receive a plurality of relatively adjustable tool elements; and

Fig. 7.isa dean section taken on the line [Prof Fig. 6. H l H Referring in detail to the drawing, 5 des eignates the body portion, of the tool socket which. is of elongated, longitudinally taperthe length of said member to provide the flat or plane face 7. At the inner end of this flattened face 7, theend face of thecylining form,.said member beingcylindricalat I .one end,as 1nd1cated at 6,and. one side he .lng cut away for the rema ning portion of drical portion 6. is undercut or inclined, as i at-S, and formed with a relatively narrow,

transversely extending shoulder 9 extendmg at right anglesto the face 7 The end 60f the socket member is provided with an integral, longitudinally projecting flange or ferrule 10 for engagement in a recess or countersink 11 provided in the end of the toolhandle H. Atapering or pointed v tang 12 projects centrally from theend 60f the tool member for engagement in a tapering bore formed in the end of the handle. The

, other end of the socket member 5 is reduced and exteriorly threaded, as indicated at ,13,

for a purpose tobe presently referred to.

'The flattened face 7 of the sockctmember has a central,longitudinally extending channel or groove 14 formed therein, and a lug .15 projects longitudinally fromjthe shoulder 9 and the base of said channel. A

. the flat side thereof, which is adapted for engagement upon the flattened face 7 of the socket member 5. One end of this socket member17 is beveled or inclined as at 19, for engagement with the beveled face 8 of the member 5, and also has a portion of its end face disposed at right angles to the axis of said socket member, as at 20, for abutting engagement against the wall or shoulder 9. The otherend of the tool member 17 is also reduced and exteriorly threaded, as at 21. 22 designates an interiorly threaded, tapering sleeve or collar whiohis second relatively small lug .16 is also formed position for active use.

adapted to be engaged upon the threaded end 13 and 21 of the socket members to tightly clamp the same together.

I have shown in the accompanying drawing a bricklayers tool 23 having ashank 24; at one end provided with an angularly offset portion 25. In the extremity of the shank 24, a notch or recess 26 is provided, and in one face of said shank, in spaced relation to the recess, a second recess 27 is formed. In connecting the tool to the handle, it will be understood that the shank 24 is first disposed in the channel 14 of the socket member 5, the lug 15 fitting into the notch 26 while thelug 16 engages in the recess 27. The tool shank is of' 'rcater thicl-zncss than the depth of the channel 14k so that when the other section 17 of the socket is arranged in position, a portion of theshank 2 1 will be received in the channel 18 thereof. The end of this socket member 17 is tightly engaged against the surfaces 8 and 9 of the member 5 and the clamping ring orannulus 22 then threaded upon the other ends of the socket members. In this manner, it will be seen that the tool shank is tightly and securely clamped and held in the channels of the socket members, and the socket member 17 is held against transverse shifting movement with respect to the member 9 by the shank of the tool.

from moving outwardly away from the member 5 by the inclined or beveled face 8 contacting with the beveled end face 19 of the member 17. In this manner, it will be seen that I have devised a very simple, effective and reliable handle socket whereby tools may be interchangeably connected therewith. A single handle may thus serve for use in connection with a large number of tool elements employed for diflerent purposes.

In Fig. 5 of the drawing, I have shown a rectangular tool head 28 which is obliquely inclined with respect to its shank 29, said shank being provided with means for connection to the handle socket as above clescribed. The hub 28 has a longitudinal opening 30 extending therethrough, in which a plurality of tool-blades '31 are adapted to be arranged. 32 designates a clamping or set screw threaded in one side of the head 28, whereby the series of tool blades may be tightly, clamped and held against movement. By loosening this screw any one of the tool elements may be projected beyond the others, as indicated in Fig. 5, in These tool. blades are preferably of different widths to. be used under different circumstances. This type oftool head is especially desirable for use .by bricklayers in removing mortar from the face of a wall, particularly beneath the The inner end of the member 17 is also prevented against cornices or ledges as it enables the workmen to freely manipulate the tool without striking the hands or knuckles against projecting portions of the wall; This is also true of the other tool illustrated in Fig. 4, since it will be obvious that by providing the offset shank thereon, the handle and consequently the hand of the workman will be disposed at some distance from the wall face in the use of the tool.

From the foregoing description, taken in connection with the accompanying drawing the construction, manner of use and several advantages of the device will be clearly and fully understood; lily the provision of my improved socket, the tool elements may be easily and quickly connected to the handle or detached therefrom, thus reducing the expense incident to the use of a large number of tools, as a single handle may be provided with the cntlre tool set. It is, of course, apparent that the socket. may be made in various sizes and of other shapes 7 than that shown, in the drawing. The form,

construction and relative arrangement of the several detail parts of the device are also susceptible of considerable modification and I, therefore, reserve the privilege of adopting all such legitimate changes as may be vided with a longitudinal channel therein said member being provided with a lug at the inner end of the channel projectingoutwardly therefrom beyond the flattened face of said member and adapted for engagegagement upon the flattened face of the body member and also provided with a channel to receive the shank of the tool member,

ment by the shank of a tool member, a coma 'plementary socket member adapted for en-' said lug engaging in one end of said chan nel, the cylindrlcal end. portion of the body 7 member being provided witli a transversely beveled face at the inner end of the channel in said member and said second nam ed socket member also having a beveled end face to engage the beveled face of the body member whereby said members are, held relative lateral movement, and means detachably engaged upon the other ends of the socket members to same together. i

2. A tool socket including complementary socket memberseach having a longitudinally extending channel, said channels when clamp the arranged in mating relation receiving the shank of the tool, one of said members being further provided With co-acting means to prevent their relative movement in a direction at right angles to the axis of the socket, the corresponding ends of said socket members being threaded, and a clamping-sleeve adapted to be engaged upon 10 the threaded ends of said members to clamp the same upon the tool shank.

In testimony whereof I hereunto afiiX my signature in the presence of tWo Witnesses.
