ART OF MAKING METAL VISES.

SPECIFICATION forming part of Letters Patent No. 394,540, dated December 11, 1888.

Application filed June 18, 1888. Serial No. 277,490. (No model.)

To all whom, it may concern:

Be it known that l, RICHARD JOHNSON, a citizen of the United States, residing at Freeport, in the county of Stephenson and State of Illinois, have invented a certain new and useful Improvement in the Art of Making Metal Vises, of which the following is a specification.

My invention relates to the production of 1o metal vises, involving, as a matter of construction, a pair of wrought-iron or soft-steel standards provided with steel-faced jaws and connected together by means of a flat lug projecting from one standard and pivotally held between a couple of correspondingly-formed lugs, which likewise proj ect laterally from the other standard.

The practice of forging and finishing by a succession of manual operations the said comzo ponent members of vises has been slow, la-

borious, and expensive, and while requiring the employment of skilled labor has failed to produce uniformly-finished work, and has further failed to produce such uniformity of 2 5 shape and construction as would at all times permit one of the such members finished up by a workman for one vise to be interchanged with a corresponding member destined by the same or some other workman for another 3o vise.

The objects of my invention are to overcome all of the foregoing defects and objectionable features heretofore incident to the hand-forging and hand-finishing of such metal 3 5 -visesg to avoid the frequent reheatings heretofore necessary; to produce said articles in a rapid, economical, and accurate way; to provide a better article, and to render the production of the vises a commercial success.

4o To illustrate my improvement, Figure 1 of the annexed drawings represents in perspective the upper portion of a blank or partiallyformed vise-standard, and indicates in dotted lines a block or blank and face-plate piled thereon. Fig. 2 represents in perspective the aforesaid blank, and Fig. 3 is a like view of the aforesaid face-plate. Fig. i represents a small block designed to form a knob on the back of the upper jaw portion of the Visestandard. Fig. 5 is aperspective view of one of the dies, which in Fig. 7 constitutes the lower die. Fig. 6 is a top plan View of said lower die, E, and represents in dotted lines the position to be occupied bythe mandrel G of Fig. 7. Fig. 7 is a section taken on a ver- 55 tical plane through both dies brought together, and indicates the standard having its jaw portion formed by the union of the blank or partially-formed vise-standard shown in Fig.

1, with blank B and face-plate C, as herein- 6o after set forth. Fig. 8 represents in perspective the upper die, E, of Fig. 7, the acting face portion of said die being underneath in accordance with the proper position. Fig. 9 represents in side elevation the jaw portion of the vise-standard of Fig. 7 placed between the finishing-die portions H and H. Fig. 10 shows in perspective the upper finished jaw portion of the vise-standard. Fig. 11 shows the vise in elevation. Fig. 12 represents a 7o portion of the vise-standard, broken for convenience of illustration, and shows the relative position of the two blanks or plates I that are to be welded thereto to form lugs for a pintle. Fig. 13 shows in perspective the 75 lower die, and Fig. 15 is a like view of the upper die for welding plates I to the vise-standard. Fig. l-l shows in cross-section said two dies brought together with the plates I welded to the vise-standard and a mandrel, M, be- 8o tween certain portions of the plates, the line of section being transverse to the length of the vise-standard. Fig. 16 shows in perspective a portion of the vise-standard with the plates of Fig. 12 welded thereto, so as to form 85 lugs a2. Fig. 17 is a perspective View of one, and Fig. 18 a perspective view of another, of apair of dies for finishing the vise-standard. Fig. 19 is a section taken on a vertical plane through the dies of Figs. 17 and 18 brought 9o together, with the block N (shown in dotted lines, Fig. 17) piled on the vise-standard and welded to the same. Fig. 2O shows the lower portion of the short vise-standard, having a lug, a3, formed by welding the aforesaid blank or block N to the vise-standard.

In carrying out my invention l provide in any suitable way a set of blanks, such as shown in Figs. l, 2, 3, and 4, wherein A is a metal blank which is to form one of the 10o vise standards CL and the body portion CL of the jaw thereon; B, a metal blank which is to form the projecting gripping portion of the jaw; C, a steel plate which is to provide a facing for said gripping portion of the jaw, and D a metal block which is to form upon the rear side of the body portion of the jawa knob,which,while not strictly necessary to the construction and operation of a vise, is invariably demanded by the trade as a matter necessary to its finish. These four blanks are piled together at a welding heat within a die, E, (such as shown in Figs. 5, 6, and 7,) and while at a welding heat vunited by the conjoint action of said die E and a die, F, which latter is represented in Figs. 7 and S. The mode of piling together the four blanks A, B, C, and D will be understood by referring to Fig. 7, wherein the separation of the blanks from one another preparatory to the operation of uniting them into a single piece is indicated by dotted lines. The action of the dies E and F serves to unite the blanks and properly shape the jaw, which, when shaped, will appear substantially as in Fig. 10. Preparatory to bringing the dies together a mandrel, G, Fig. 7, may be fitted within the hole CL2, which is formed through the stand ard portion CL of the blank A as an opening for the usual j aw-adjusting bolt.

After the blanks A, B, C, and D have been united to provide the standardl with a proporly-constructed jaw, the jaw is desirably subjected to the action of the edge-finishing dies H and H', which serve to obliterate such web as may have been formed by the action of the dies E and F.

The foregoing mode of operation requires no change in making either of the two jaws of a vise, whereby by repeated operations any desired number of vise-standards having uniformly-constructed jaws may be produced. In these vises one of the vise-standards is provided with a pair of laterally-projecting ears or lugs, CL2, which are arranged parallel with one another, while the other standard is provided with a single laterally-projecting flat lug, CL3, Fig. l1, adapted to enter the space between the said pair of lugs, so that by providing the lugs with pivotrholes the single lug can, by a suitable pivotbe hinged between the pair of lugs.

In order to provide vise-standards with the lugs CL2, I provide a couple of metal blanks or plates, I, Fig. l2, and avise-standard, heat all three to a welding heat, then pile them within a die K, (such as shown in Figs. 13 and 14,) and then by the conjoint action of the said die K and a die, L, (such as illustrated in Figs.'14 and 15,) unite the said blanks and standard, so as to provide the latter with the lugs CL2, as shown in Figs. ll and 16.

The proper relative position of the piled blanks I and standard is to some extent indicated in Fig. l2, but more accurately shown in Fig. 14, wherein the separation of the piled blanks and standard preparatory to the union of the three is indicated by dott-ed lines. In said figure a steel mandrel, M,.is shown placed between the projecting portions of the blanks I, in order to insure properultimate shape of the lugs and permit the dies to bevel the edgesV of the blanks.

As a means for providing certain other of the vise-standards with the single lugs 0,3, I first provide a vise-standard and a metal blank, N, which, as indicated in dotted lines, Fig. 17, consists of a rectangular block or plate, preferably beveled at one end. This blank N and the vise-standard are then heated to a welding heat and placed together in a die, P, as illustrated in dotted lines, Fig. 17, and then by the conjoint action of the die P and a die, P, as in Fig. 19 the blank and the standard vare united, so as to provide the standard with .the single lateral lug CL3. (Shown in Figs. 11 and 20.) After uniting the blank N and the standard, the article should be subjected to the action of dies Q and Q, so as to remove any web which may have been formed in welding together the said blank and standard, and after producing a standard with a pair of lugs, CL2, and a standard with a lug, CL3, all of said lugs can be bored to provide them with suitable pivot-holes.

In Fig. 1I one of the standards is shown provided with an extension, CL4, which, however, has no relation to my'invention.

By the foregoing operation one workman can rapidly turn ont vises, whereby the employmentof several workmen, as heretofore incident to the old art, is avoided. Thevises made in accordance with my improvement are also superior in uniformity of form and structure Aand have a far better finish than can be at-` tained by hand-forging, and obviously much saving in time, labor, and expense is effected.

-While the blanks C, which serve to face the vise-jaws, are made of steel,l the remaining blanks are all made either of wroughtfiron or soft steel, wrought-iron being, however, preferred. It will be obvious that the vise-jaws could be formed upon the standards without the knobs which the blanks D are intended to form upon the outer or rear sides of the jaws, and that after piling together the blanks A, B, and O, and uniting them as hereinbefore set forth, the knob could be subsequently applied. It Will, however, involve greater economy in and rapidity of production to pile together the blanks A, B, C, and D in the first instance.

What I claim as my invention is l. The within-described improvement in the art of making vise-jaws, consisting in'preparing the blanks A, B, and C, piling them together at a welding heat, and while at such heat uniting said blanks by die-pressure, substantially as set forth.

2. The within-described improvement inthe art of makingfvise-jaws, consisting in preparing the blanks A, B, C, and D, piling them to- IOO IIO

art of providing vise-standards with the single lugs CL3, consisting in piling together at a Welding heat a Standard, a, and a blank, N, and While at a Welding heat uniting' said 15 blank and standard by die-pressure, Substantiall57 as set forth.

RICHARD JOHNSON.
