A. M. CUNHA.

WRENCH.

APPLICAIION FILED JULY 1, 1919.

ANTHONY M. GUNHA, OF PROVIDENCE,

BHODE ISLAND.

WRENCH. 7

Application filed July 1, 1919.

To all whom it may concern:

Be it known that I, ANTHONY M. CU NHA, a citizen of the United States, and resident of the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Wrenches, of which the following is a specification. N

This invention relates to so-called socket wrenches and more particularly to an auxiliary detachable handle for a socket wrench, and the object of this invention is to provide such an auxiliary handle of simple and practical construction which is adaptedto be readily connected to and disconnected from the main wrench to complete the forming of a T-shapedoperating handle for a wrench.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a plan view illustrating my auxiliary handle as applied to a ratchet wrench.

Fig. 2- is a side elevation of the parts shown in Fig. 1 and showing the socket head of the auxiliary handle in section.

Fig. 3 is a view of the under side of the socket head portion of the auxiliary handle; showing the same as applied to a wrench, the handles of both parts beingbroken off.

Fig. 4- is a perspective view iliary wrench handle detached.

Fig. 5 is a side elevation illustrating the general arrangement of the auxiliary handle in the act of being applied to a wrench, but before the handles are positioned in alinement with each other.

Referring to the drawings, lO'designates the head portion of a so-called socket wrench of the ratchet type, the square hole 11 in the center thereof being for the purpose of receiving the bars of the usual sockets, and this wrench head is ally-projecting, operating handle 12.

It is found in practice that where the usual long or extended bar is employed, between the wrench head and the socket members (not shown) that it is often difficult to hold this bar in an upward.- position while a heavy tension is being applied at the end of the wrench handle 12, therefore it is found advisable in some cases to provide of my aux- Specification of Letters Patent.

provided with a later- Patented Mar. 1, 1921. Serial No. 307,908. r

a wrench with tending from each of the opposite sides of the head.

As it is not convenient under all circumstances to use a T-handle wrench, I have provided. an auxiliary handle which may readily connected to the regular slngle handled wrench, whereby a single handled wrench may be convertedinto a double or T-handle wrench when desired.

Toacoomplish this in tical way I have provided a socket-shaped head 13 having side walls 14 formed of thin stock which is somewhat flexible or yield able, the socket being open at its top and preferably provided with a bottom plate 15 to strengthen and stiffen the side. walls, which bottom plate is providedwith an open ing 16 through which the socket operating extension bars may be passed into the square of the wrench head.

The side walls of this auxiliary handle.

head are cut away at one point forming an opening as at 17 through which the handle 12 of the wrench may be passed in connecting the two together, the opposite edges 18 of the side walls on the opposite sides of the opening 17 are arranged to engage opposite sides of the wrench handle 12 to assist in carrying the operating strain applied through the handles.

In order to further support and stiffen these side walls about the opening 17, I have provided a bridge member 19 which extends from the opening and connects the upper edge of the side walls together. The head portion of the auxiliary handle is provided with a laterally extending operating bar or handle 20 which extends substantially in line with the the auxiliary handle is positioned thereon in order to complete the T-shaped handle of the wrench.

The side walls 14 of the head of the auxiliary handle are shaped to form a socket to receive and frictionally engage the outer surface of the head of the wrench, so that this head will be crowded or forced between these walls into the socket and so finnly secured therein by friction and the two members may be readily disengaged by forcing the handles out of alinement with each other a simple and praca T-handle, that is, one exl extremely s mple, inexpen;

' serve the privilege sive and practical in its construction, may be readily connected to and disconnected from a socket wrench without the use of screws or other adjustable binding means.

The foregoing description 18 directed solely toward the construction illustrated, but I desire it to be understood that I reof resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only bythe terms of the appended I claims.
