JAMES H. SHEPHERD, OF IDAHO SPRINGS, COLORADO.
WRENCH.
Specification of Letters Patent.
Patented sept. 1 1, 190e.
Application filed December 21, 1905. Serial No. 292,722.
T all whom it may concern:
Be it known that I, JAMES H. SHEPHERD, afcitizen of the United States of America, and a resident of Idaho Springs, in the county of Clear Creek and State of Colorado, have invented certain new and useful Improvements in Wrenches, of which the following is a specification.
This invention relates to certain new and useful improvements in wrenches and it has for its objects, among others, to provide a strong, durable, and efficient wrench composed of minimum parts and those easily assembled and readily operated.
It comprises a fixed jaw with a shank, a movable jaw receiving said shank, and a handle in which both the shank of the iixed jaw and the portion of the movable jaw receiving said shank are received and with which they have independent threaded engagement. The parts are held against accidental separation by means permitting of readily disassembling the parts when desired.
Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be particularly pointed out in the appended claims.
The invention is clearly illustrated in the accompanying drawings, which, with the numerals of reference marked thereon, form a part of this specification, and in which- Figure 1 is a side elevation of a wrench constructed in accordance with my present invention. Fig. 2 is a substantially central longitudinal section through the same. 3 is a perspective view of the xed jaw and its shank separated from the other parts. Fig. 4 is a perspective view of the movable jaw detached.
Like numerals of reference indicate like parts throughout the several views.
Referring now to the details of the drawings, 1 designates the fixed jaw, and 2 its shank, which latter is rectangular in crosssection for the greater portion of its length, and beyond the rectangular portion is the reduced cylindrical portion 3, having at its outer end an opening ftherethrough The rectangular portion is provided for about one-half of its length upon its opposite edges lwith screw-threads 5.
6 is the movable jaw. It has a tubular shank portion 7, provided with a rectangular bore or passage 8 therethrough, the same being of ashape and size corresponding substantially to that of the rectangular portion Fig.
of the shank of the iixed jaw. This tubular shank 7 is provided exteriorly with the threads 9, which are oppositely disposed to the threads of the shank 2.
10 is the handle, which may be given any desired exterior configuration and is provided interiorly with a bore of two diameters. Of these the smaller is provided with screwthreads 11 to receive the threads 5 of the vshank of the fixed jaw, while the larger diameter is provided with the interior threads 12, oppositely disposed to the threads 11 and receiving the threads 9 on the tubular shank 7 ofthe movable jaw.
The parts of the wrench are assembled by slipping the shank of the xed jaw into the hollow shank of the movable jaw, then slipping the handle over the xed jaws shank and over the tubular shank of the movable jaw and screwing the handle onto the threads 5 of the shank of the fixed jaw and then inserting a spring-ring or the like 13 through the opening 4 of the portion 3 of the shank2. This holds the parts against separation. Adjustment of the jaws relatively to each other is accomplished with ease by turning the handle in one direction or the other. The parts may also be assembled by first screwing the shank of the movable jaw into the handle and then applying the handle to the shank of the fixed jaw and then applying the fastening-hook or other device 13, the relative adjustment of the jaws being attained in the same manner as above described.
From the above it will be seen that I have devised a simple, strong, and durable wrench which is capable of easy manipulation, composed of but three parts and those capable of manufacture at minimum cost, and when assembled not liable to derangement, injury, or breakage.
The disposition of the interior threads of the handle is such that when the shank of the movable jaw is turned to its limit within the IOO handle the latter will befree from its threaded IIO the handle, and removable means passed through the end of the shank of the fixed jaw for preventing separation of the parts said means permitting free adjustment of the aws.
j 2. A wrench comprising a :(ixed jaw with threaded shank, a movable. jaw having a threaded shank receiving the shank of the iixed jaw, and a handle having different internal threaded diameters receiving both ofv said shanks and having direct opposite threaded engagement with both of them at all times for simultaneous adjustment in opposite directions and means engaging the end of the shank of the fixed jaw )tor preventing separation of the parts and at no time interfering with the manipulation of the parts to change the relation of the jaws to each other. 3. A wrench comprising a fixed jaw having a shank with threaded portion and reduced portion with opening therethrough, a movable jaw having an exteriorlythreaded shank and a passage therethrough for the shank of the iixed jaw, and a handle having oppositely-disposed threads of different diameter and directly receiving the threads of the two Shanks, the end of the shank of the movable jaw having a bearing in the end of the handle and means engaging the ends of the shank ol' the iixed jaw for preventing separation of the parts and at no time intertering with the manipulation of the parts to change the relation of the jaws to each other.
4. A wrench comprising a fixed jaw with shank having exterior threads7 a movable jaw having a shank with opposite-disposed exterior threads and a passage therethrough for the shank of the iixed jaw7 a handle having two interior diameters with oppositely-disposed threads one at all times engagin directly the threads of the shank o1@- the ed jaw and the other at all times engaging directly the threads of the shank of the movable jaw, and a detachable fastener engaging the shank of the lixed jaw outside and bevond the end of the handle to prevent separation of the parts the adjustment of said parts being at no time ailected by said fastener.
