CONSTRUCTION FOR BRACES.

Specification of Letters Patent. Patented.

Application filed October 24, 1918. Serial No. 259,484.

To all whom it may concern:

Be it known that I, WALTER I. TUTTLE, a citizen of the United States, and a resident of Providence, in the county of Providence and State of Rhode Island, have invented an Improvement in Construction for Braces, of which the following is a specification.

This invention relates to the construction of braces and the like, and more particularly to the end or thrust handles thereof. One of the objects thereof is to provide a construction of the above type of eflicient action and strong, dependable structure. Another object is to provide a construction of the above type whichshall be light in weight and cheap in manufacture. Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the structure hereinafter described and the scope of the application of which will be indicated in the following claim.

In the accompanying drawing in which is shown one or more various possible embodiments of this invention,

Figure 1 is a side elevation cut awa through the handle; and

Fig. 2 is a vertical section through the handle portion thereof, on an enlarged scale.

Similar reference characters refer to similar parts throughout the several views of the drawing. I

Referring now to Fig. 1 of the drawings, there is shown a brace having a crank portion 1 with shank portions or end members 2 and 3. It is to be understood that these shank portions may be formed inte al or separate from the intermediate portions of the brace, and that the term shank is used broadly throughout.

Secured to the end member 2 is the device which is operated by the brace, here shown as a socket 4, to form a socket wrench.

It is clear, however, that a chuck or other tool, or tool-holding member may be employed at this point, and many of the advantages of the invention achieved.

This invention is a modification of that disclosed in my co-pending application, Serial No. 256,646, filed Oct. 31, 1918, and the features thus far described are common to the two forms.

Referring now more particularly to the opposite end of the brace, especially as shown in Fig; 2 of the drawing, there is preferably provided a sheet metal thrust handle member 5.

This member is preferably composedof a sheet metal. cylindrical bearing portion 6, surrounding the free end of shank 3, and havingan integral outstanding annular flange. 7. 7 i

A sheet metal. grip. portion 8 has the-usual external confirmation of brace grip handles, and is symmetrically fitted over the flange 7 the said flange being curved to fit closely in the interior of the grip portion.

The grip portion is permanently secured to the flange 7, by rivets, spot welding, or simllar means, as shown at 9.

The unitary structure of the grip portion 8, and the bearing portion 6, are mounted on the end of brace portion 3 in a manner to permit the shank 3 to rotate within the bearing portion, but to prevent the grip and its bearin portion from coming oil the end of the shank.

I prefer to achieve this object in this apin Fig. 1 of the drawings, and is formed by gradually tapering a portion of the shank as shown at 10, and providing an abrupt shoulder 11 at right angles to the axis of the shank, joining that part of the shank of smallest diameter with the main body of the shank below it.

The cylindrical bearing portion 6 is preferably swaged over the gradually tapering portion of the groove, and a small space 12 is left between the inner edge of the swaged portion and the shoulder 11.

The swaged portion thus prevents the thrust handle from being removed fromthe shank portion. The central portion of grip member 8 preferably abuts the extreme end 14 of shank member 3, thus limiting the movement of the thrust handle toward the socket portion 4. The thrust handle is thus maintained by the abutment at 14 and the swaged portion 10 from rattling on the shank 3 without interfering with the freedom of rotation of the shank within the bearing portion 6.

The above construction forms what is termed the thrust handle as distinguished from a possible handle on the crank of the brace, and it is to be understood that this term thrust handle is broadly used throughout.

In the action of the device, the shank member 3, is securely locked into the thrust handle member, but is free to rotate with respect thereto regardless how much pressure may be applied to the thrust handle. No rotating parts, however, are exposed to the hands of the user.

It will thus be seenthat there is provided a construction in which the objects of this invention and the above-noted as well asother advantages are gained.

As various possible embodiments might be made of the above invention and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.

I claim:

In brace construction, a swiveled handle comprising in combination a thin hollow metal handle member having a curved inner surface, a bearing member provided with a tubular bearing portion and with an 0utwardly extending annular flange which is curved to fitthe inner surface of said handle member, adjacent its central portion and is secured thereto and reinforces the same substantially throughout its radial diameter, said handle member being shaped to substantially inclose said bearing member, and a shank member having a bearing within said tubular portion of said bearing member and a circular recess with which said bearing member interlocks.

In testimony whereof, I have signed my name to this specification this 21st day of October, 1918.

WALTER I. TUTTLE.
