DIE FOR MAKING PIPE-WRENCHES. I
SPECIFICATION forming part of Letters Patent No. 464,352, dated December 1 1891.
Serial No. 390,847. (No model.)
, to the letters of reference marked thereon.
, Our present invention has for its object to provide improved dies for making chain pipewrenches, whereby practically the whole of the wrench may be made at a single operation; and to these and other ends it consists in certain improved construction hereinafter fully described, the novel features being pointed out in the claims.
In the drawings, Figure 1 is a bottom plan of a complete wrench; Fig. 2, a side elevation,
and Fig. 3 a top plan view, of the same; Fig.
nect the jaws A A by a firm connection. The
4, a plan view of the face of the upper die; Fig. 5, a plan view of the face ofthe lower die; Fig. 6, a longitudinal sectional View of the two dies when brought together.
Similar letters of reference in the several figures indicate similar parts.
In Figs. 1, 2, and 3 are shown views of the complete wrench made by our dies, E representing the operating-handle; A, the serrated steel-faced jaws at the forward end; B, the hub or projection on the side opposite the serrations on the jaws, and O a'small fillet or web formed on the body and serving to conhub Bis, after being formed in the dies hereinafter described, slotted, as shown, for the engagement of the links of a chain F, attached to the wrench by a staple G, as usual. The manner of using the wrench is well known and needs no further description.
Heretofere thisform of wrench has been made by taking a bar of iron and welding the steel jaws A separately thereto; but such aproceeding is not only expensive, but produces an inferior article, and we find that by the use of our improved dies the whole wrench-body can be easily and cheaply formed by a single operation. The lower die shown in Figs. 5 and 6 is provided with the recess E, for the handle portion of the Wrench, the curved recesses A A at the forward end and the convex projection D between the latter having the inclined rear side 0 for forming one side of the inclined rib or web O between the jaws. The upper die is provided with the recess E E, corresponding to part Ein the lower die, the recesses A A for the straight part of the jaws A A, the recess B for forming the projection B, and the projecting portion I concave on its outer surface to correspond with the part D on the lower die and having the rear side inclined at C to form the other side of the .Web or rib O; The faces of the dies are preferably curved, as shown, so that the parting line will extend approximately through the center of the jaws A from the end. The inclined parts O the article, and a small piece of steel is secured at ornear the end, constituting a wearing-face for the jaws A A. Then the whole blank is heated to a Welding heat, placed between the dies, which are in a suitable hammer or press, and by a few blows the Wrench is formed, the metal flowing into recess B and the steel face being welded into position on the jaws A. The metal between the jaws A is then trimmed out, leaving the web O, which materially strengthens them, and the slot is cut in the projection B, the jawsAserrated, and the staple and chain attached in the usual manner.
WVe claim as our invention- 1. The hereinsdescribed dies for forming wrenches, having the recesses A, A, E,E", and B, and the projections D D, substantially as shown. 7
2. The herein-described dies for forming wrenches, having the recesses A, A, E, E, and B, and the projections D. D", with the inclines O O thereon, substantially as shown.
3. The herein-described dies for forming wrenches, having curved faces and the re cesses A, A, E, E, and B, and the projections D D, substantially as shown.
