This invention comprises novel and useful improvements in an adjustable pipe wrench and more specifically pertains to a pipe wrench ofV the chain type specifically adapted forengaging rods, shafts, casing sections and timbers for use in the oil well'industry.
The primary object of this invention is to provide an improved pipe wrench of the chain' type. which shall have an improved and easily manipulated adjusting. action to accomodate different..
sizes of pipesand the like to bemanipulated.
A further object of the invention is to provide an improved pipe wrench of the chain type wherein one end of the chain is adjustably slidably mounted upon the exterior surface of a tubular handle and the other end of the chain is adjustably secured in the interior of the tubular handle.
A still further object of the invention is to provide an improved pipe wrench in conformity with the preceding objects in which an improved resilt ient, easily engaged or released fastener is provided for adjustably securing one end of the chain in the interior of the tubular handle.
These, together with various ancillary features and objects of the invention which Will later become apparent as the following description proceeds, are attained by the present invention, a preferred embodiment of which has been illustrated, by Way of example only, in the accompanying drawings, wherein:
Figure 1 is a side elevational View showing a preferred embodiment of pipe wrench incorporating therein the principle of this invention, parts of the wrench being broken away and shown in section;
Figure 2 is a horizontal sectional View taken substantially on the plane of the line 2-2 of Figure 1;
Figure 3 is a vertical transverse sectional view taken substantially upon the plane indicated by the sectional line 3-3 of Figure l; and
Figure 4 is a further vertical transverse sectional view taken substantially upon the plane indicated by the sectional line 4-4 of Figure 1.
Referring now more specifically to the accompanying drawings, wherein like numerals designate similar parts throughout the various Views, it will be seen that rthe adjustable pipe wrench chosen. to exemplify the principles of this invention includes a tubular handle l of any desired size, the same being provided with a hand grip portion l2 at one end of the same, the handle being open at its other end for a purpose which will later be set forth.
. 2 Y Rigidly attached to the exterior of the tubular body I is a toothed pipe jaw I4 of any'desired character and size, preferably disposed at one end of the member I0.
The pipe wrench further` includes a'exible chain l5 which may be of any conventional and known design for this type of Wrench, the chain having one end pivotly vattached as'at I8 to a depending lug 20 integrally attached toa slide 22 constituting a sleeve which is slidably received upon the exterior surface of the-tubular member l0. Obviously by this means one end of the chain may be readily adjusted longitudinally of the tubular member as found desirable or necessary.
The other end of the chain beyond the customary loop adapted to engage a pipe and retain the same against the Xed toothed jaw I4, is slidably received within the open end of the tubular member I0 and is adjustably retained therein by a novel mechanism or fastener to be now described.
For this purpose, the tubular member I0 is provided with a plurality of longitudinally spaced diametrical bores or apertures 24 and a novel fastener isadapted to be seated in selected diametrical apertures and to extend through one of the links of the chain for securing the end of the chain in xed position in the tubular member.
The fastening member in accordance with this invention may conveniently consist of a single unitary resilient wire which includes a ring portion 26 resiliently and slidably embracing the exterior surface of the tubular member l0, this ring portion having a longitudinally extending curved portion 28 whoseend is provided with a diametrically disposed finger 30. Due to the resilience in the curved portion 28, the 'linger may be selectively inserted into or withdrawn from the selected diametrical apertures 24. The inherent resiliency of the portion 28 will yieldingly retain the finger 30 in seated position in selected apertures and through the adjacent link of the chain for securely locking the end of the chain in adjusted position in the tubular member.
From the foregoing, it will be apparent that the device may be utilized by encircling the pipe or member to be turned with a loop of the chain 16, by placing the toothed jaw I4 against the pipe as shown in Figure 1, and sliding the member 22 into position to tighten the chain about the pipe, and pulling the other end of the chain into the tubular member l0 and locking the same in proper position by the resilient fastener.
From the foregoing, the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes Will readily occur to those skilled inthe art after a consideration of the foregoing specication and accompanying drawings, it is not desired to limit the invention to the exact construction shown and described, but al1 suitable modifications and equivalents may be resorted to, falling Within the scope of the appended claims.
