' FOUR WAY COMPRESSION PLIER I Filed Sept. 15, 1953 FIG. 4
W INVENTOR. K 7 WILLIAM A. BARNES Ll/ 0% wv/ KM ATTYS noun WAY COMPRESSION PLIER WilliamA. Barnes, Utica, N. Y., assignor to Utica Drop Forge & ToollCorporation, a corporation of New York Application September 15, 1953, Serial No. 380,322 3 Claims. (Cl. 78-82) This invention relates to compression tools in general and relates more specifically to a tool having four anvil jaws converging upon a common compression area from four directions.
An object of this invention is to converge a plurality of jaws upon a common compression area to perform compression work.
Another object of this invention is to provide a tool which opens for easy positioning of the jaws around the work from a lateral direction.
And another object of this invention is to drive primary jaws from a prime power source, and to close secondary jaws with a drive from the primary jaws.
Other objects and a fuller understanding of the invention may be had by referring to the following description and claims, taken in conjunction with the accompanying drawing, in which:
Figure 1 is a plan view of a manually operated adaptation of this invention;
Figure 2 is a sectional view through the operative portion of the device taken along line 2-2 of Figure 4;
Figure 3 is a perspective view of the operative portion with portions broken away for clarity of illustration; and
Figure 4 is a side view of the device.
The tool illustrated in the drawings has been found to be useful for several different applications and accordingly is shown in a basic design rather than having an adaptation for any particular use. Furthermore, it is illustrated in the drawings as a hand tool although power driven operation is entirely within the scope and intent of the invention.
One particular adaptation of the invention has been found useful for the closing of electrical terminals from four different sides. Another extremely useful adaptation has been the union of stranded wire into a solid slug wherein the strands are united in a solid phase bond. There has been perfected a process, and many specific tools, for the union of two or more metallic pieces at a temperature less than the normal welding temperature of the metal in a solid phase bond. If more information is desired in regard to such uniting of metal and the basic principles involved, then reference is made to United States Patent No. 2,639,633 and also United States Patent No. 2,639,634.
The tool of this invention is a high pressure precision tool which may be adapted for many uses, including the low temperature solid phase bonding referred to. For example, when stranded wire is cut off and the insulation stripped back if desired, the strands are quite likely to spring apart. If these strands are to be united together a or to another object by pressure in a solid phase bond, it will be necessary to clean them such as by wire brushing, which further disperses the wire strands. The tool of this invention may be employed after such cleaning to bring the strands of wire together and to pack them into one solid slug end.
With reference to the drawing, the Figure 1 is a geny 2 eral representation of a manually operated tool embodying the features of this invention. The reference character 10 indicates the tool generally. The tool as illus-: trated comprises a first and second lever 11 and 12 pivoted together by means of a pivot 21., On one side of the pivot 21, the levers 11 and 12 define anvil jaws 13 and 14 having jaw work faces 17 and 18.
Secondary jaws 15 and 16 are pivotally carried by the levers 11 and 12 and driven thereby. Pivots 22 and 24 join the jaw 15 to the handle end of lever 11 and the anvil jaw end 14 of lever 12 respectively. Pivots 23 and 25 join the secondary jaw 16 to the handle end of the lever 12 and the, anvil jaw end 13 of lever 11 re spectively. Slots 26 and 27 receive the pivots 24 and 25 in order to carry the secondary jaws and yet provide movability of the levers 11 and 12., v a
Secondary jaws 15 and 16 are provided faces 19 and 20, formed in a manner faces 17 2.116118. a
The operation of the tool may be readily understood by reference tothe Figure 2.. Operation of levers 11 and 12 will openyand close the anvil jaw portions, 13 and 14 andmove the surfaces 17 and 18 through generally. arcuate paths between the open position illustrated in Figure 2 and the closed position represented by the dotted outline configuration of the same view. As the levers 11 and 12 close and open, the pivots 22, 23, 24 and 25 carry the secondary jaws 15 and 16 through a substantially rectilinear path between the open position illustrated, in the full lines of Figure 2 and the dotted outline of the same jaw member. The secondary jaws 15 and 16 also converge upon a compression area outlined by the jaw work faces 17, 18, 19, and 20 in the dotted outline. By moving laterally, the jaws 15 and 16 open to permit the engagement of the tool laterally upon a workpiece rather than to require a longitudinal feeding of the workpiece between jaw members. The opening, or mouth, is represented by the reference character 28.
The work faces 17-20 are illustrated as plane fiat surfaces. This is in keeping with the general nature and adaptability of the tool. Suitable particular faces may be substituted for specific work pieces.
The operation of the tool presents a convergence of four work faces upon a general compression area wherein a workpiece is confined and placed under a considerable pressure as the work faces 17 and 18 move around an arcuate path against the opposing faces 19 and 20 which move on a rectilinear path.
Although the invention has been described in its preferred form with a certain degree of particularity, it is understood that the present disclosure of the preferred form has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to without departing fromthe spirit and the scope of the invention as hereinafter claimed.
