GUSTAVE O. CARLSON, OF WETI-IERSFIELD, CONNECTICUT, ASSIGNOR OE ONE-THIRD TO HENRY HANSON, OF MIDDLETOWN, CONNECTICUT,- AND ONE-THIRD TO CARL O. HEDSTROM, OF PORTLAND, CONNECTICUT.
TOOL.
Application filed December 18, 1925. Serial No. 76,235.
This present invention relates to tools and more particularly to a type of tool having companion members that have a rotatable and shifting connection with each other.
It is the object of this invention, among other things, to improve the pivotal connection between the jaws, whereby the same may have the maximum strength, occupy the minimum space and will not permit the accidental separation of such jaws.
To these, and other ends, my invention consists in the tool, having certain details of construction. and combinations of parts, as will be hereinafter described and more particularly pointed out in the claims.
Referring to the drawlngs, in which like numerals of reference designate like parts in the several figures;
Figure 1 is a view of a tool constructed in accordance with my invention, wherein the broken lines indicate a position of one of the jaws, other than asshown in full lines;
Figure 2 is a fragmentary view of one of the jaws;
Figure 3 is; a fragmentary view of portions of both of the jaws adjacent to the pivotal connection; and
Figures 4: and 5 are two elevations of the pivot pin.
The embodiment of my invention is herein disclosed in connection with a pair of pliers, but it is adapted equally as well to a wrench or other tool having similarly connected movable members.
In the drawings, 10 and 11 represent two jaw members which may or may not be.
provided with gripping teeth 12 and cutting blades 13, as desired. Obviously, the form and construction of these jaws may be varied indefinitely.
The jaw 11 is provided with two openings let and 15 connected by a throat 27 of less width than the diameter of the openings. The outer face of this latter jaw, concentric with the openings 14 and 15, is provided with the inwardly flaring faces 16.
The pivot pin is constructed with a shank 17, having substantially the same diameter as the openings 14 and 15, and two oppositely disposed fiat faces 18, the space between which is substantially the width of the throat 15. One end of the shank 17 is provided with a head portion 19, the sides of which are provided with flaring faces 20 that connect the top. of the head with the rounded portion of the shank 17 and flaring faces 21 of substantially the same angle as the faces 20, which extend from the top of the head portion 19 to the fiat faces 18. The space between the flaring faces 21 at the top thereof is substantially the same as the width of the open space between the points 22 on the jaw member 11, where the flaring faces16 intersect each other. The jaw 10 is provided with an opening 23, of substan tially the same diameter as the shank of the pivot pin, that terminates in a flaring face 24:. The jaws and pivot pin are assembled in the position substantially as shown in Figure l, with the shank of the pivot pin projecting through the openings 15 and 22-5, after which the outer end of the shank is upset to form the head 25, the outer walls of which contact with the flaring face 241- and secure the pin against movement. This upsetting operation is facilitated by providing a recess 26 in the shank of the rivet. When thus assembled, the jaws 10 and 11 are inseparably secured together and the outer faces of the heads 19 and 25 are flush with the outside faces of the jaw members and without projecting parts, as is common in tools of this character. Thus, any pressure caused by the use of the tool in the direction of the axis of the pivot pin will not disturb the relative position of the jaws themselves. This is not true in the usual pivotal connection of tools of this character, as lateral pressure has a tendency to rotate the nut or other fastening means upon such pivot during the movement of the jaw. This shifting of the jaws away from each other seriously impairs the efliciency of the tool. Such action is more certain to occur when the tool is being used as cutting pliers.
Having described my invention, what I claim as new and desire to secure by Letters Patent, is
1. In a tool of the character describ'd; a pair of jaw members, one of which has a plurality of connected semicircular openings therethrough, which openings terminate at one end at a bevel face that extends therearound and intersect each other at a face of the jaw member, the space between the oppositelydisposed intersecting points being less than that of the diameter of the openings; a pin lined in one member projecting through the openings in the other member and having a head thereon with a bevel underface that projects over and contacts with the bevel faces surrounding the openings.
2. In a tool of the character described; a pair of jaw members, one of which has a plurality of connected semicircular openings therethrough, which openings terminate at one end at a bevel face that extends therearound and intersect each other at a face of the jaw member, the widest point of the beveled face being substantially coincident with the face of the jaw member; a pin fixed in one member projecting through the openings in the other member and having a head thereon with a beveled underface that projects over and contacts with the beveled faces surrounding the openings.
3. In a tool of the character described a pair ofjaw members; and a connecting member, as a pin, for movably securing the members together, whereby the lateral thrust of the members is taken upon surfaces that are beveled relatively to the axis of the connecting member-,said pin'having' a shank with two rounded faces having a common center, two fiat faces connecting the rounded faces and substantially parallel with each other, a head having round and flat faces beveled relatively to the axis of the pin and forming extensions of the side and rounded faces of the shank. I
4:. In a tool of the character described; a pair of members, one of the members having a plurality of openings therethrough connected by a throat of less width than the openings and each opening having a flaring face at the outside of the member; a pin fixed in one memberand projecting through an opening in the other member with a head thereon, the underside of which is flaring and projects over the flaring faces, said pin having oppositely disposed flat faces upon the shank thereof that are spaced apart substantially thesanre distance as the sides of said throatand substantially flat sides upon said head at an angle to the aforesaid flat faces,t-h-at are spaced apart substantially the same distance as that between the points where said flaring faces intersect each other.
,5. In a tool of the character described; a pair of members, one of the members having a pluralityof openingsTtherethrough con nected by-a throat ofless width than the openings and each opening having a flaring face the outsideof the member; a pin fixed in. one member and projectin'g through an opening in the othermember with a head thereon that projects over said flaring faces, said pin oppositely disposed fiat faces spaced apart substantially the same distance as the sides or said throat and substantially flat sides upon saidl'ieadfspac'edapartsubstantially the sanie distance as that'b'etween the po nts where said flaring faces intersect each other, the ends of said pin being s'ubstant'i'ally'fl'ush with the outside faces of the o members, the 'L'indersi'des of the head having "flaring faces at substantially the same angle relative to the axis of the pin, as the flaring faces surrounding said openings.
In testimony whereof, I have hereunto ailixed my's gnature.
