ATTACHMENT FOR WRENCHES.

which may be used'in connection with socket wrenches for expediting the removal of cap screws and bolts. It is a purpose to provide a tool of this character which will find a broad range of uses, and convenientuses, 1n

and around automobiles, during the assembly and disassembly of automobile parts, and in other mechanical operations.

It is a purpose" to provide an attachment tool for socket wrenches which has clamping characteristics and which may be readily attached and detached from an ordinary socket wrench, and which will function to grip one end of acap screw or bolt in order to hold the head or nut thereof while the socket wrench is bein turned to unscrew said bolt or cap screw from its anchored po sition.

With the above principal objects, and others, in view, the invention has relation to the attachment tool for socket wrenches, an exampleof which isdescribed in the following specification, pointed out in the appended claims, and portrayed in the accom panying drawings, wherein: l

Figure 1 shows an attachment tool for socket wrenches mounted in service position upon a socket wrench, and clamped in posi' tion to hold a bolt nut to facilitate removal of a bolt by the socket wrench.

Figs. 2 and 3 illustrate a sideand edge view of the attachment tool removed from the socket wrench with which it operates.

Figs. 4' and 5 respectively illustrate sec tions taken upon the line 4- 1, and the line 5-5 of Fig. 1.-

An attachment tool for socket wrenches built according to the plansjof this invention, consists of a wrench head mounted on a shank member, with the shank member mounted upon the stem of a socket wrench and spaced therefrom in order to cooperate Specification of Letters latent.

with the socket wrench in removing bolts prises a hook or bearing receptacle 11 inte grally made with a plate 12 said plate having out-turned spaced ears 13.

A hole polygonal in cross section is formed through each "ear 13 to mount the shank 7. I A collar 14 is ustably clamped on the shank by a screw 15 or other means. The collar 14: limits one-way movement of the shank in the guide bracket but permits said shank to move upwardly from the guide On the other end of the shank member there is fitteda retaining guide'wliich comprises a lock plate and guide'bracket. This last named guide bracket functions similar to the one aforedescribed. This guide bracket comprises a plate 16 with spaced cars 17 and outstanding bearing receptacle. 18. V i

The bearing receptacles 11 and 18 are shaped in the form of hooks but function as bearings to rotatably retain the stem of a socket wrench as later seen. The hooks or bearing receptacles are in alinement to receive the cylindrical stem of a socket wrench. A lock-plate is associated with the retaining guide, and functions to lockably retain the stem-of a socket wrench in the bearing receptacles. The lock plate consists of the plate 20 withan over-hanging edge 21. 'The forward edge of the lock plate 20 is cut on a radius approximately the radius of the handle or stem of a socket wrench with which the attachment tool is associated. This arcuate construction of one end of the lock plate is shown in Fig. 5.

Thelock plate is punched out in the center of the plate 20 which provides an elongated opening 22, and a portion of metal is left integral with the plate 20 in order to form a lock dog 23. The over-hanging shank member 7. The guide bracket comthe position shown in Fig. 2. The retaining guide is secured upon the shank member by ascrew 24 which anchors the retaming guide in fixed position upon the lower'end of the shank member.

A COIlQCl CO IIlPIT-BSSIOH spring 25 is confined on' the shank member between the r the spring and sliding the shank through guide bracket and retaining guide in order to holdthe collar ll and shank? in limited movement relative with the guidebracket 12. The wrench head SVmay be movedoutwardly from the guide bracket by pressing the member-1 2.

The above description essentially covers the construction and assembly of the attachment tool for socket wrenches. A socket wrench of any suitable type may be connected with this attachment tool. fOne form of socket wrench is shown in Fig. 1 which comprises a socket head 27 adapted to receive the hexagonal bolt head 28. socket head is made integral with a stem 29, and the stem is provided with a hand grip 30. This laterdescription essentially, in a manner, discloses a conventional socket wrench. The description to follow will set out the combination and use of these two tools. i

In order to oin the socket wrench and at tachment tool together for joint operation, the lock plate 20 will be displaced from normal position as shown in Fig. 2. r This will openupthe receptacle 18 and permit the stem 29 of the socket wrenchto be inserted within the confines of the bearing receptacles 11 and18. The lock plate will then be pushed back into normal position and, engage the stem 29 to confine it in rotatable relation i with the guide 12 and retaining member 16. The'forward edge ofthe car 13 acts to retainand guide the stem 29 upon the attachment tool., The attachment tool and socket wrench are, therefore, joined in spaced relation, and the socket head 27 and the hex-receptacle 9 are alined one with the other. The wrench head 8 will be pushed upon one end of the bolt tobe removed, while the socket 27 will be pushedupon the other end of the bolt. The socket tool 29 is now rotated to unscrew the bolt while the attachment tool stands in firm and steady position to prevent the head of the nut from turning.

V] hen the lock plate said purposes.

The

' By using this combination tool the most stubborn or rusty bolts may be quickly removed. The invention is presented tofill a long-felt need for a mechanics tool of this nature and for carrying out the afore- Having thus described my invention, what I claim as new, and desire to secure by Letters Patent is:

An attachment tool for socket wrenches, comprising; ,-a pair of spaced guides, a shank member slidably confined inone guide and anchored to the other guide, a spring confined on the shank member. between the guide members, a wrench head carried by the shank member, and ,a lock plate provided with a slotted opening confined on the shank member and'movable relative thereto in order to hold .a socket wrench in operative connection with the attachment tool. I

r 2. An attachment tool for socket wrenches, comprising; a "pair of spaced guides, a shank member slidably confined in one guide and anchored to the'other guide, a spring confined on the shank memhead carriedby the shank member, anda lockplate associated with theshank mem ber andmovable relative thereto in order to holda socket wrench in operative con-' nection with the attachment, tool.

3. An attachment tool. for socket wrenches, comprising; a pair of spaced guides employed to hook around a socket wrench, a shank member carried by the spaced guides, and a lock plate confined on the'shan'k member to cooperate with one of the guides to lock the attachment tool in working relation withza socket wrench. 1
