SOLOMON CAMPBELL, OF HARTFORD, CONNECTICUT, ASSIGNOR TO THE ALLEN MANUFACTURING COMPANY, OF HARTFORD, CONNECTICUT, A CORPORATION OF CONNECTICUT.

SOCKET WRENCH.

To all whom it may concern.

Be it known that I, SOLOMON A. CAMP BELL, a citizen ofthe United States, and resident of Hartford, in the county of Hartford 6 and State of Connecticut, have invented certain new and useful Improvements in Socket Wrenches, of which the following is a specification. I

This invention is intended primarily fol 1 use in or as a part of a socket wrench, although it may be used as a universal joint connection between a handle or other operating member and work engaging tools or parts other than wrench sockets.

One object of my invention is to provide means whereby the handle or other operat' ing member can be connected through a universal joint to any tool which otherwise could be connected directly to the handle or operating member, and at the same time to so form the universal joint that it may itself serve as a work engaging part.

' As important features of my construction I provide a universal joint including two 2 socketvinembers having hexagonal or other non-circular sockets of different sizes, one, for instance the smaller, being adapted for detachably receiving a handle or operating member, and the other being adapted to receive and fit a nut, bolt' head, or the like whereby for that one size of nut the device serves both as a universal joint and as a wrench socket or other work engaging part. In connection with the universal olnt I provide an adapter having the opposite ends of the proper length, size and shape to fit the opposite end sockets of the universal joint.

Thus, with the universal jointconnected to the operating member and the adapter connected to the universal joint, the adapter will present a terminal portion which corresponds in shape and size to the terminal portion of the operating member, and will receive any socket or other work engaging part which could otherwise'be directly connected to the operating members In the accompanying drawings I have illustrated one embodiment of my invention.

In these drawings Fig. 1 is a side elevation of an operating member. j

Fig. 2 is a longitudinal section throng my improved universal joint.

Fig. 3 is a side elevation of my improved adapter.

Fig. 4 is a transverse section through the adapter on the line 4-4 of Fig. 3,

Figs. 5 and 6 are longitudinal sections through different sizes of sockets which may be connected either to the adapter or to the operating member.

Fig. 7 is a side elevation of the universal joint mounted for use as a work engaging part, and

Fig. 8 is a side elevation showing the universal joint and adapter for operating a separate work-engaging part.

The handle or operating member, as shown in Fig. 1, forms no rtion of my present invention and may he constructed substantially as illustrated in my prior Patent 1,371,350, issued March 15, 1921. The construction illustrated includes a hexagonal bar 10, which may detachably engage in a socket in a head 11, which latter may detachably receive a bar 12 forming an operating lever or T handle. The head 11-may include ratchet connections, as disclosed in my prior patent above referred to, althou h such, are not illustrated in detail herein." 0 far as the present invention is concerned, any suitable means may be employed for rotating or oscillating the handle or operating member 10. 1

My improved universal joint includes two socket members 13 and 14, each provided with a pair of ears or lugs 15 which receive between them, and are pivotally connected to, an intermediate block 16. The pivot pins 17 and 18 which connect the two socket members to the block 16 are in planes at right angles to each other. As an important featureof the universal joint, the two socket members 13 and 14 are provided with sockets 19 and 20, which are of similar form, but of different sizes. One of these sockets, for instance the socket 19, is of such form and size as to receive and fit the end of the operating member 10. The latter may have a ball 21 imbedded therein to serve as a stop, and a separate ball 22 retained in place, but pressed outwardly by a spring so as to serve as a resilient retainer when this end ortion of the operating member 10 is inserts in the socket 19. The socket 20 is adapted to serve as a work engaging part, and is intended to receive and fit some specified size of nut or other work part. Preferably it is of the proper size so that when the universal joint is connected to the handle or operating member the device may serve as a fourth: bearing socket wrench for the Ford car.

In connection with the universal joint I provide an adapter as shown in Figs. 3 and 4. This includes an end ortion 23 of a length, size and shape to t the socket 20, and an end portion 2a which corresponds in shape and size to the terminal portion of the handle member 10. In other words, it is adapted to fit the socket 19 of the universal joint. This adapter is preferably formed b a piece of bar stock similar to that of WhlC the handle member 10- is formed, and this may have shrunk, driven or otherwise secured (in, a jacket part to provide the end portion 23 of difl'erent diameter. The two end portions may have separate spring pressed balls mounted in radial sockets to serve as resilient retainers. The ball. 25 which is in the larger end may be of a larger diameter than the thickness of the wall of the jacket, so as to serve as an additional means for preventing the endwise removal or displacement of the jacket.

By means of my improved universal joint and adapter the end of the handle 10 may be inserted in the socket 19, and the larger end of the adapter inserted in the socket 20 so that the exposed end of the adapter will correspond in size and shape to the end of the operating member 10, and will receive any form of socket or other work engaging part which could otherwise be directly attached to the end of the operating member 10.

In Figs. 5 -and 6 I have shown a pair of wrench sockets 27 and 28 both of which have apertures 29'at one end, hexagonal in cross section, and adapted to fit either the end of the operatingmember 10 or the end rtion 24 of the adapter. The socket mem rs 27 v and 28 at their other ends have sockets 30 reaches the adapter. Thus, by means of my invention, I provide a universal joint which may be inserted between the operating member and the work engaging part, or may serve itself as a Work engaging part, or when removed permits the direct attachment of the other work engaging parts to the other operating member.

When the joint itself is employed as the work engaging part, it permits the insertion of the tool into a comparatively narrow space, which is not possible where the joint merely forms a connection between the handle and the Work engaging part.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

A socket wrench including a handle bar,

a pair of sockets having universal joint connections, one of said sockets having an opening at its outer end of a size to fit and'detachably receive the end of said bar, and the other of said sockets having an opening of larger size, an adapter having one end of the .through the universal joint and adapter, the

adapter being of a length to be substantially completely received, one half in the last mentioned socket and the other half in the second mentioned socket of the pair, and the end of the handle bar and both end portions of said adapter having spring pressed means for frictionally engaging within the sockets to hold the bar, sockets and adapter in the desired assembl Signed at I'filltfOl'd, in the county of Hartford and State of Connecticut, this 11th day of March A. D. 1922.
