WALTER I. TUTTLE, OF PROVIDENCE, RHODE ISLAND.
To all whom it may concern:
Be it known that I, WALTER T. Toms, 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 Wrenches, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.
This invention relates to wrenches and more particularly to-wrenches of the socket type. One of the objects is to provide a simple and practical device of the above nature having ready adjustability to nuts of difierent sizes. Another object is to provide a wrench of the above type of inex ensive and durable construction which sha 1 be etficient in action and convenient in use. Other objects will be in part obvious and in part hereinafter described. Y
The invention accordingly consists in the features of construction, combinations of elements and arrangement ofparts. which will be exemplified in the structure hereinafter described and the scope of the applica tion of which will be indicated in the following claims.
In the accompanying drawing, in which is shown one of the various possible embodiments of this invention,
Figure 1 is a perspective view of a wrench in operative position;
Figs. 2, 3, 4 and 5 are plan views of the same showing different operative positions of the parts; I
Fig, 6 is a longitudinal sectional view.
Similar reference characters refer to similar parts throughout the several views of the drawing.
Referring now to Fig. 1 of the drawing, there is shown an outer tubular member 1 and it may here be noted that the term tubular is used in a broad sense and does not imply any specific cross section of the member designated thereby.
The member 1 is preferably of substantially circular cross section at the central part and its ends 2 and 3 are preferably drawn downwardly to reduced diameter. These ends are shaped to fit difierent nuts and such nuts may be difi'erent in shape as well as in size, although in the embodiment.
herein shown each end fits a hexagonal nut, the end 3 fitting a smaller nut than that with which the end 2 is adapted to co-act.
Specification of Letters Patent.
Application filed February 29, 1916. Serial u 81,086.
As best shown in Fig. 6 of the drawing, there is slidably fitted within the member 1 a device comprising a pair of sockets 4 and 5. The socket 4 fits telescopically within the end 2 and preferably takes a nut of a similar shape but smaller size than the latter part. a In like manner, the socket 5 fits slidably within the end 3 and also takes, in this embodiment, a smaller nut of similar shape. These several parts are so proportioned that the socket 4 fits over a nut which is slightly smaller than that accommodated by the end portion 3 and hence four difierent nuts may be accommodated by the entire device.
The parts 4 and 5 ar short hollow members preferably of steel and preferably having their inner ends turned inwardly as at 6 to fit about a connecting tube 7, the ends of which are headed over as indicated at 8. Also this tube 7 may be slightly expanded so as to hold these several parts in substantially rigid relation.
The length of travel of the inner device comprising the sockets 4 and 5 is limited by a pair of lugs 9 out free from the outer tubular member and turned inwardly to provide a stop which engages the shoulders formed by the inner ends of the sockets. In this simple manner, means are provided whereby an exactly predetermined length of travel of the parts is permitted and this arrangement is not only cheap and simple but there is no chance of the parts wedging or binding in use. p
When it is desired to use the end socket 5, the parts are positioned as shown in Fig.
'2 of the drawing, with a handle or rod 10 inserted through registering perforations 11 at the end 2 of member 1. If it is desired to use the socket 4, the rod. 10 is inser ted through: perforations 12 in the end 3'. I In each of these positions, the unused socket rests against the rod and hence locks the parts in position. For larger nuts, the end 3 may be used as shown in Fig. 4 of the drawing, the rod 10 being inserted through perforations 13 in the socket 4, and for even larger nuts, the rod is inserted through perforations 14 in the socket 5, these positions being respectively shown in Figs. 4 and 5 of the drawing. In these positions, moreover, the rod rests against the outer end of the outer member 1 to lock the parts in position.
By using these parts in the form shown, there is not only gained cheapness, inasmuch as the outer part may be formed from round tubing, but greater rigidity and ease of handling, due to the large diameter of the outer member and its smooth surface. The inner device comprising the slidable sockets is also of inexpensive construction as a short length only of tubing is required, and furthermore, if one of the sockets become deformed in use, it is readily replaced independently of the other socket. If desired, moreover, the tube 7 may be of such size as to permit a bolt to pass therethrough thus adapting the device for use over a nut which is threaded downwardly to a considerable extent upon the bolt. The short inner sockets moreover, largely reduce the chance of binding which might arise if the inside parts were fitted throughout their length within the outer member.
The method of use of the device will be substantially clear from the above description, and it may be noted that it is necessary merely to shift the rod or handle 10 to the desired registering opening in order to prepare the proper socket for use with a nut.
It will thus be seen that there is provided a device in which the several objects of this invention are achieved and in which the above and other 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. drawing is to be interpreted as illustrative and not in a limiting sense.
What I claim is:
1. In a device of the class described, in combination, a tubular member with ends respectively shaped to fit different nuts, a device having irregularities in shape slidably fitted in said tubular member and having ends respectively shaped to fit different nuts, and an integral projection extending inwardly from said tubular member and positioned to be engaged by irregularities in shape of said inner device and limit its sliding movement therein.
2. In a device of the class described, in combination, a tubular member, the ends of which are of different sizes and each shaped to fit a nut, a pair of members each of which is shaped to fit a nut and to rest slidably within said first member, means combination, a tubular member having an intermediate portion round in cross section and having ends of different sizes and each shaped to fit a nut, a pair of members each of which is shaped to fit a nut and to rest slidably in said first member, means con necting said last members one with another, and an integral projection extending inwardly from said tubular member and positioned to be engaged by the inner ends of said inner members andlimit their sliding movement.
4. In a device of the class described, in combination, a tubular member round in cross section at its central portion and having its ends respectively forced into angular shapes respectively adapted to fit nuts of different sizes, a pair of sockets respectively slidably fitted in the ends of said first member, and respectively shaped to fit nuts of different sizes, a member of reduced cross section connecting the inner ends of said sockets one to another and holding them in spaced relation, a projection extending inwardly from said outer member and positioned to be engaged by the inner ends of said sockets to limit their sliding movement therein, and means adapted to rotate said device about its longitudinal axis.
In testimony whereof I have signed my name to this specification.
