Application filed June 20, 1924. Serial' No. 721,371.
This invention relates to new and useful improvements in wrenches.
The object et the invention is to provide a wrench having a plurality of gripping members substantially equally spaced so th at in gripping tubular member, the latter is engaged at a number of points, thus minimizing crushing.
Another object is to provide two pairs of grips arranged so that the work is initially gripped by diametrically opposite grips, and the other grips brought into engagement with .the work as the wrench is tightened thereon, thus reducing slipping and'assuring a than bite, as well as applying equal pressure at the points of gripping.
. A construction designed to carry out the invention will behereinatter described together with other ieatures of the invention. The invention will be more readily Lin-- derstood from a reading of the following specification and by reference to the accompanying drawings, in which an example of the invention is shown, and wherein:
Fig. 1 is an elevation of the j aw portions ot a wrench constructed in accordance with my invention, the parts being in initial gripping position, y
Fig. 2 is a vertical sectional view of the same, the wrench having been tightened on the work,
Fig. 3 is a sectional view on the line 3-3 ot Fig. 1, and
Figs. A and 5 are details of modified :terms of grips.
In the drawings the numeral l0 designates a handle having at its upper end a rigid jaw 11 extended laterally to overhang the handle. Immediately below the aw the handle depends through a yoke 12 which is tulcrumed on a bolt 13 extending the handle near its inner edge. The handle has a boss or enlargenient 1A under the jaw opposite the bolt 13. A horizontal recess 15 is made in the boss, relatively below the bolt for receiving a coiled spring 16. The spring has its outer end engaging the yoke for holding the latter in position on the handle.
A movable jaw 17 overhangs the jaw l.11 and has an integral shank 18 depending therefrom at substantially right angles thereto. rlhe shank has screw threads 19 and passes through spaced ears 20 extending :from the yoke. A milled circular nut 21 engaged on the shank is conined between the ears and by rotating said nut the shank 1s displaced longitudinally of the handle and the jaw 17 moved toward or from the jaw 11, as is usual ink this type of wrench.
A gripping die or block 22 is mounted in the forward portion ot' the lower jaw 11 which hasa'recess or cavity 22 for receiving said die. A similar die 23 is mounted in a recess 23 in the inner or rear part of the said jaw. The upper jaw has a cavity 26 in itsy underside, and receives outer and inner dies 2A and 25 respectively. die reerred to is circular in form and has ratchet teeth on its periphery directed in a counterclockwise` direction. y
l Each die is removably mounted but held against rotation by a. polygonalv tubular bolt 27 passing through the center of the die and its respective jawV and held in place by a machine screw 28. The openings in the dies as well as in the respective jaw snuglyreceive the `bolts 27, so that said dies cannot rotate on the bolts nor can the boltsrotate in the openings of the jaws. By this arrangement when a section of teeth become worn thek bolt 27 may be removed, the die rotated sulicie-ntly to bring a new section y ot teeth into use, and the bolt replaced. In Fig. 4 I have shown octagonal form of die 29 and in F ig. 5 a square form of die 30. Any suitable form may be used.
It will be seen that four dies are employed to grip the work. The inner die 23 may be mounted a short distance above the outer die 22. Thus when the wrench is applied to the work A the die 22 will more readily swing past the work so that the die 23 may initially engage the work. In ap plying the wrench the inner die 23 of the lower jaw 11 and the outer die 24 of the upper j aw are initially engaged with the work A at substantially diametrically opposite points as is shown in Fig. 1. When the handle 10 is swung in a counter-clockwise direction the dies are moved relatively around the work to bring the otherdies 22 and 25 into gripping engagement therewith, lthe four dies taking bites atsubstantially equildistant points and applying approximately equal pressure.
' It will be seen that the initial slippage will be taken up by the dies 23 and 2A and when the following dies 22 and 25 are brought into contact with the work, the slippage will be stopped and a firm grip will be taken. The provision for adjusting the dies circumerentially makes `for long life and a gener? ous supply of sharp teeth. The wrench is adjusted and used in the same manner as other wrenches ot this type.
Various changes in the size and shape of the different parts, as well as modifications and alterations may be made within the scope ot' the appended claims.
that I claim, is:
1. In a wrench, the combination of an upper jaw7 a pair ot spaced dies havingcircumferential teeth and being circumferenl tially adjustable in the upper jaw, a lower aw, a second pair of dies having circumferential teeth and being circumferentially adjustable in the lower jaw, and means -tor 'astening all thev dies against rotation.-
\ 2. In a wrench, the combinati-on ot an upper jaw and a lower jaw, and dies mounted in opposed relation in said jaws each having teeth on. their peripheries, all dies 4bein-g adjustable circun'iferentially to present new teeth when those in use become worn, said dies being `fastened against rotation.
3. In a wrench, the combination ot an upper jaw, a pair of spaced dies having circumferential teeth and being circumferentially adjustable in the upper jaw, a lower jaw, a second pair of dies having circumferential teeth and being"circumterentially adjustaloleA in the lower jaw, and means for fastening all 'the diesy against rotation, the dies being so related that 'a 'single upper and a single lowerdie initially engage the work and the remaining dies subsequently engage the work.
Li. In a wrench7 the combination 'of an upper jaw and a. lower jaw pivoted to swing relatively ot the upper jaw, and a plurality oi" dies mounted in opposed relation in both the jaws, some of said dies being located in the jaws so as to initially grip opposite sides ot the work fully received in the aws, and the remainder ot said dies being located so as to subsequently grip another portion ot the work when the lower jaw is swung, the tirst named dies substantiallj7 retaining their initial gripping` engagement.
In a. wrench the combination of an upper jaw and a lower jaw, and dies held against rotation and positioned in the jaws so that diametrically opposite dies initially engage the work and additional dies arc brought into engagement with the work as the jaws are rotated relatively of the work.
6. In a wrench, the combination of a handie, a lower jaw mounted on the endo't the handle, said lower jaw being recessed, an upper jaw 'having its underside recessed and ove'rhangin'g the lower jaw, a yoke on the handle in which the upper jaw is adjustable, a pair ot spaced toothed dies mounted in the recessed portion of the lower jaw, and a second pair 'oit spaced toothed dies mounted in the recessed portion of the upper j aw over the tiret pair of dies, said dies being circumierentially adjustable.
In testimony whereof I affix my signature.
