This invention relates to combination or multiple tool sets and more particularly tothe varietycomprising a plurality of oper ating parts such, for example, as a series of wrench "sockets of various slzes, assembled upon the tool itself. One object of the inform of construction capable of being pro-- duced at a relatively low cost. a To these and other ends the invention resides in certain improvements and combinations of partsall as will be hereinafter more full descrlbed, the novel features being pointe claims at the end of the specification.

In the drawin s:

Similar reference numerals throughout the several. views indicate the same parts.

The embodiment of the invention at present preferred comprises a main tool portion 10 in the form of a brace constructed of an integral metal rod having an elongated shank portion 11 and at its opposite end :1

out in the handle. or breast piece 12, with an intermediate angular crank portion 13. The rod has in the present instance, a uniformly round cross-section except at the shank portion 11, the lower or key end and preferably the entire extent. of which has -a cross-section of uniform polygonal or hexagonalshape. The shank portion is thus adapted i to slidably receive a plurality'of hollow wrench sockets 14 for nuts of different sizes. The sockets have an opening formed therethrough as indicated, one end of which is hexagonal in shape and of different sizes in the different sockets to cooperate with various sized nuts. The other end of the opening through the sockets is adapted to slidably receive the brace shank so that the series of. sockets may becollectively assembled or strung on the shank as shown in Fig. 1. The uniform size and shape of the shank throughout facilitates the assembly 7 and removal of the sockets which do not require to be rotatably adjusted or otherwise positioned before being slid off the shank. The relatively .close fit between the sockets and'shallk furthermore prevents the sockets from rattling about on the shank.

Means are provided for retaining the sockets in assembled relation on the shank when not in use comprising a cotter-pin 15, Fig. '2, inserted inatransver'se opening adjacent the end of the shank. By removing this pin a socket of desired size may be taken from the shank and fitted to the key end of the latter for use as shown in Fig. 2.. Pin 15 serves also as a sto for the sockets in use. To retaina socket in such operating position on the shank end the latter has arecess' 16 formed therein adjacent its extremity in which is carried a ball 17 pressed outwardly by a spring 18 so as to project slight- 1y beyond the surface of the shank for rictionally engaging and retaining a socket thereon. The end Walls of opening 16 are set slightly inwardly after the insertion of the ball to limit its outward movement. I

In Fig. 6 is shown an adapter comprisin a socket 19 constructed for engagement witfi the shank end or key as in the case of the sockets 14 and carrying in its other end a transverse pin 20 on which is mounted for universal movement in any suitable manner the spherical end 21 of an auxiliary shank end or key 22 adapted, for engagement with the series of sockets 14 to afiord a universal form of connection between the latter and the tool when the work requires operation of the latter at an angle. This feature and also the length of the shank portion 11 render the tool capable of use for conven iently engaging and rotating a nut located in an inaccessible position or at an inconvenient angle to the axis of the tool.

The tool embodies an advantageous form of construction for the handle or breast piece 12 in which the rod 10, Fig. 8, has a reduced portion 23 at its extremity providing a sto shoulder 24 preferably of substantial heiglit. A collar 25 is assembled on portion 23 with an end flange 26 bearing against shoulder 2-1, the collar and flange being as shown of substantial thickness and strength. Handle 12 is formed with a central opening through which collar 25 is rotatably inserted with the handle supported by flange 26. A spring washer 27 is then preferably placed on collar 25 and the latter upset or rolled over at its end as at :28 to secure the handle on the collar. These latter parts may be thus assembled as a unit and then placed on the rod end 23 and the latter upset or rolled over as at 29 to hold the parts in place. This afl'ords a substantial form of support for the handle which may of course be varied in its-details although the form described has been found practical and inexpensive. In addition to the series of sockets already described the tool comprises an element 30 in the form of a sheet-metal clip, Fig. 4, folded upon itself as at 31 with spaced arms 32 embracing the shank end or key and perforated to pivotally receive the pin 15. The outer folded end 31 of the clip is shaped for engagement with one or more recessed portions of an object to be rotated as for example the valve of an internal-combustion motor for rotating and grinding the latter. Element 30 is pivotally supported on the shank by the means described which assists in operating it at inconvenient angles and also provides for compact positioning on the shank when not in use as shown in Fig. 1. Element 30 may of course be adapted for turning screws and various other objects.

The tool comprises also operating parts for lifting an object as for example, a motor valve and valve stem for grinding and other operations on the latter. The parts comprise an element 33, Fig. 7, having a socket portion 34 adapted to be fitted to the shank end or key and a bifurcated end 35 formed to embrace and engage a valve stem part for lifting the latter. To provide a means of suspension or fulcrum for the tool during such use there is su plied also an element or link 36 formed witli openings 37 and 38 at its two ends preferably lying in a common plane as shown. Openin 37 adapts the element for assembly on the race rod as shown, this opening being preferably such as to g revent accidental detachment from the tool. he other opening 38 is such as to form a hook for engagement, for example, with the studs for holding the engine manifold on the cylinder block. These parts together with the elongated shank of the tool, provide a convenient implement or lever for lifting the valves of a motor for the purposes de scribed.

At 39, Fig. 9, is an L-shaped wrench of a well-known form which may be supplied with the tool for use with the working parts thereof under particular conditions. This wrench is provided with a frictional device or spring-actuated ball 40 similar to that reviously described, for retaining the workmg parts in operating position on the wrench. The material of the latter, furthermore, is pressed up as at 41 to form a lug serving as a stop for socket parts.

The operation of the tool has been described in connection with the description of its construction and it is apparent that the tool provides a relatively large number of working parts particularly useful in corn nection with an internal-combustion motor. These parts are associated with the tool in a convenient manner facilitating assembly and detachment as well as eflicient use thereon individually, and the construction is substantial and rugged but simple and inexpensive throughout.
