Specification of Letters Patent.
Patented Oct. 10, 1905.
Application filed February '7, 1905. serial No. 244,598.
To all whmn if nut-y concern:
Be it known that I, VILLIAM O. TARR, a citizen of the United States, residing at Orleans, in the county of Orange and State of Indiana, have invented certain new and useful Improvements in a Combined Nut and Pipe \"Vrench; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention has relation to wrench construction, and more particularly to a form of wrench adapted equally well as a pipe-wrench and as a wrench for all sizes of nuts; and my invention consists of certain novel features of combination and construction of parts, the preferred form whereof will be hereinafter clearly set forth, and pointed out in the claim.
The main object of my invention, among others, is to provide a reliably-efficient form of wrench of the character specified which will have the capacity of ready and easy adjustment to fit it for its various uses.
A further object of my invention is to form a wrench of the character set forth of the fewest number of parts, enabling the wrench to be very cheaply and expeditiously manufactured and sold at a comparatively small price.
Other objects and advantages will be hereinafter made clearly apparent, reference being had to the accompanying drawings, which are considered a part of this application, and in which-- Figure 1 shows a perspective view of my invention complete, ready for use, with the end of the handle broken away for convenience of illustration. Fig. 2 is a similar view to that presented in Fig. 1 except that itshows a longitudinal central section. Fig. 3 is aside elevation of my invention complete adjusted as a nut-wrench.
For convenience of description the various parts of my invention and cooperating accessories will be designated by numerals, the same numeral applying to a similar part throughout the several views, and, referring in detail to the drawings, 1 indicates the shank or body portion of my wrench, which is provided at one end with a suitable form of handle and at the other end with a fixed head or jaw 2, the said shank or body portion being provided, preferably upon its upper side, with a plurality of ratchet teeth 3, formed, as shown, by leaving the outer edges of the teeth flush with the general surface of the shank, as
clearly set forth in Fig. 2. It will be observed that the fixed jaw has a plain or smooth inner face, which is disposed at right angles to the plane of the shank, it being understood that said fixed jaw is preferably integrally formed with the shank. .l have also provided a movable jaw 4, having the integral loop-like members 5 and 6 extending loosely around the shank and also having the outward extension 7, said extension being designed as a housing for certain working parts of my wrench, as will be hereinafter specifically pointed out.
By reference to 'Fig. 2 it will be seen that the inner side or part of the extension 7 contiguous to the shank is cut away or recessed, as indicated by the numeral 8, and within said recess 1 mount the detent 9, having upon its inner side a plurality of ratchet-teeth corresponding to and designed to engage the ratchetteeth 3 upon the shank, and in order to place the said detent under ready manual control of the operator 1 provide a controlling-lever 10, having the thumb-piece 11, said lever being pivoted in the slotted opening 12, as designated by the numeral 13.
By reference to Fig. 2 it will also be observed that the detent 9 is held normally in engagement with the ratchet-teeth upon the shank 1 by the compression-springs 1a and 15, which are seated in suitable recesses in the jaw &, and since the inner end of the lever 10 is connected to the detent by the link member 16 passing loosely through an aperture 17 it follows that when the thumbpiece 11 is pressed downward the detent will be raised, and the entire movable jaw l may be readily r'eciprocatingly adjusted upon the shank and disposed at any point desired relative to the lixed jaw 12 or to the interposed jaw 18, which latter is provided upon its outer side with a straight or smooth surface corresponding to the inner surface of the fixed jaw, while its inner surface is cut away or beveled and further provided with a plurality of ratchetteeth, as indicated by the numeral 19, said teeth being designed especially for action upon pipes of various sizes. 1f deemed desirable, the opposing face of the movable jaw 4 may also be provided with a plurality of ratchett-eeth corresponding to and designed to cooperate with the ratchet-teeth 19, or said jaw may be left smooth, as may be deemed productive of the best results.
The auxiliary jaw 18 is normally held in engagement with the fixed jaw by means of the locking-rod 20, which for convenience of manipulation is provided with the thumb-piece or handle 21, as shown in Fig. 1.
In Figs. 1 and 2 I have shown my wrench adjusted as a pipe-wrench, while in Fig. 3 I have shown the adjustment adapting my Wrench for turning nuts, it being understood that any size of pipe and all the varying sizes of nuts may be readily acted upon by a proper adjustment of the movable jaw 4. The link member 16 is threaded at one end, so as to be readily detached from the detent.
Believing that the construction and manner of using my wrench have thus been made clearly apparent, further reference to the details is deemed unnecessary, and while I have described the preferred combination and construction of parts I desire to comprehend in this application all substantial equivalents and substitutes. 4
iliary jaw; of a movable jaw mounted upon the shank and having a recess in that face thereof contacting with the teeth of the shank, and a groove in its outer face, said groove and recess communicating through an aperture, a toothed detent slidably mounted within the recess, springs interposed between said detent and one wall of the recess to hold the detent normally in engagement with the shank, said springs being seated in recesses in the jaw, a lever fulcrumed between its ends within the groove and adapted to work within said groove, and a link member detachably secured to the detent at the center thereof and slidably mounted within the aperture, said member being pivoted to one end of the lever.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
