PATENT OFFICETH FRED W. BLACKMAR, OF PROVIDENCE, RHODE ISLAND, ASSIGNOR ONE-HALF TO LEWIS M. BLACKMAR, OF I ROVIDENCE, RHODE ISLAND.
WRENCH.
Specification of Letters Patent. Pate t d J l 25 1922 Application filed April 22, 1921. Serial No. 463,628.
To all whom it may concern: I
Be 'it known that I; FRED W. BLeoKMAR, a citizen of the United States, residing at Providence, in the county of Providenceand State of Rhode Island, have invented certain new and useful Improvements in renches, of which the following is a specification.
This invention relates to improvements 1n socket wrenches and has as one of its pri-- mary objects to provide a wrench of this type which will be adapted for application to nuts or bolts located in places inaccessible to the ordinary wrench and whether the nut or bolt be located behind an upstanding flange or other part or opposite or adjacent to a part which would ofier an obstruction to the use of the ordinary wrench. Another object of the invention is to provide a socket wrench which will be applicable to different nuts or bolts-having faces of different number and which may furthermore be. applied to the nut or bolt to be tightened or loosened, with the handle of the wrench extending at practically any angle made necessary by reason of the presence of obstructions.
In the accompanying drawings:
Figure l is a top plan view of the wrench embodying the invention, a hexagonal nut being shown in dotted lines within the socket of the wrench;
Figure 2 is a view partly in side elevation and partly in longitudinal section through the wrench;
Figure 3 is a View similar to Figure 2 illustrating one mode of application of the wrench.
Generally speaking, the wrench comprises a head which is indicated by the numeral 1, and a handle which is indicated by the numeral 2. The head 1 has upperand lower sides 3 and 4 located in parallel planes, and the head is preferably exteriorly cylindrical except that at its lower portion it is exteriorly beveled, as at 5, immediately above the lower face 4 so as to adapt the lower end of the head to more readily escape any obstructions whichmay be in the way of its application to a nut or bolt. The head is formed with a socket 6 concentric to the headon nut to which the head of the wrench is applied, as clearly shown in Figures 1 and 3 of the drawings, the notches 8 are substantially equally spaced from each other throughout the circumferential extentof the lnterior wall of the socket and are of a number which is a multiple of four' and six, in the present instance twelve, whereby the wrench may be used either with square or-hexagonal nuts and may be applied to the same when located at a variety of different angular positions relative thereto, thus permitting the same wrenchto be used both upon a given standard size square nut and a standard size hexagonal nut and applied thereto from a plurality of different angular positions to adapt the wrench not only for use with both square and hexagonal nuts but particularly adapting the same for use in positions where the locations of'adjacent parts prevent the wrench from being given more than a small angular movement at each application.
The handle 2 extends substantially at right angles radially with relation to the axis of the socket 6 and is joined with one side of the head 1 by an integral connecting shank 9. This shank portion 9 extends diagonally,substantially at an angle of45 between the handle 2 and the adjacent side of the head 1, being integrally united with the said side of the head at a point suitably spaced above the lower face & thereof and practically flush with the' up er face 3. .Thus the lower end portion of t e head may be engaged with a bolt head or nut which is seated for example in a socket or countersink without the end of the shank interfering with the introduction of said end of the head into the socket, the shank 9 under such conditions of use extending upwardly at an angle of inclination from the obstruction. Under other conditions of use as for example as illustrated in Figure 3, the wrench may best be employed by applying its upper end to the nut or bolt to be loosened or tightened. It will therefore be evident that due to the angular disposition of the shank 9 with relation to the handle 2 and head 1 of the wrench, the wrench is adapted to be employed either in the position shown in Figures 2 and 3 or in an inverted position, and in locations where it would be impossible to make use of the wrench if the handle 2 extended directly radial from the side of the head 1 in a plane between the upper and lower faces thereof.
Having thus described the invention, What is claimed as new is:
1. A socket wrench comprising a cylindrical head, a handle, and a shank connect ing one side of the head and the handle, the' being provided with a circumferential series of notches to receive the corners of a nut or the like, and the head being exteriorly tapered circumferentially in the direction away from the juncture of the shank with-the head.
2. A socket wrench comprising a head having a socket the interior wall of which is provided with a circumferential series of notches substantially equally spaced from each other throughout the circumferential extentof the interior wall of the socket, the number of notches formed in the socket maaoee being in excessof six and a multiple of both six and four to receive the corners of a four- 3. A socket wrench comprising a head, a
handle, a shank connecting one side of the head and the forward end of the handle, the said handle and one face of the head occupying substantially parallel planes, and the said shank extending diagonally beyond the saidface of the head and between the same and the handle, the head having a socket the interior wall of which is provided with a circumferential series of notches equally spaced from each other throughout the circumferential extent of the interior wall of the socket the number of notches formed in the socket being in excess of six and a multiple of both siX and four to receive the corners of a four-sided or six-sided nut when located at a variety of different angular positions relative thereto.
In testimony'whereof I afiix my signature.
