Get: 13 P. M. BURMAN MULTIFORM TOOL Filed March 7, 1925 I Arromss xf Patented Get. 13, 1925.
UNITED STATES {P PETER M. BURMAN, OF PRESTON, WASHINGTON.
MULTIFOBMVTOOL.
Application filed March 7, 1925. 'SeriaI'NO. 13,907. i
To all whom it may concern Be it known that 1, PETER M. BURMAN, a subject of King of Sweden, residing at Preston, in the county of King and State of lVashington, have invented certain newand useful Improvements in Multiform Tools, of which the following is a specification.
This invention is directed to tools of the plier or like type, wherein the jaws are conveniently interchangeable to permit the use of jaws of varying types with the same handles. 4
It has been heretofore proposed to provide tools of this type with interchangeable jaws, but in these instances, means are provided whereby the jaws are held in operative positions, with such means providing independent fastenings. With this type, the extra parts become worn in use, are liable to loss, and are not effective after continued use for holding the jaws rigidly in position.
The present invention is directed to jaws and cooperating handle means integrally formed for locking cooperation to permit the jaws as an entirety to be readily removed or applied without loss of time and with certainty of a rigid holding when applied.
The invention is illustrated in the accompanying drawings, in which Fig. 1 is a view in elevation, partly broken off, one of the jaws being in operative posi tion and the other in partly applied position,
Fig. 2 is an inner face view of one of the handle members, constructed to receive the removable jaw Fig. 3 is a section on line 33 of Fig. 2; and
Fig. 4 is a view in elevation of a slightly modified form of aw.
The improved tool comprises the usual handle portions 1 and 2, terminally formed with disks 3, adapted to be arranged in contact and connected by the usual pivot pin 4:, the disks being formed with the usual cooperating notches 5 to serve as wire cutters. Each handle member beyond the pivot disk, is formed to provide a receiving extension 6 in the form of a rectangular bar-like projection. This extension is formed near its juncture with the disk with a cylindrical recess 7, opening through the inner face of the extension. The extension is further formed in said inner face with a channel 8, communicating with the recess 7, the walls of the channel being inwardly convergent. The outer free end of the extension. is
formed with a channel 9 which communicates with the channel 8 and extends across the free end of the extension, Each jaw is formed at its outer end as at 11, with that particular formation to indicate the use of the jaw, that inthe form shown in ig. 1 having a serrated gripping face 12slightly recessed at 13. Below the jaw proper, there is provided an extension 14 terminating with an offset cylindrical member 15, adapted to snugly seat in the recess 7. Above the cylindrical member, the jaw extension is provided with a rib 16, shaped for wedging cooperation with the channel 8, that portion of the extension immediately underlying the jaw proper having a rib 17 to seat in the channel 9.
In applying the jaw, the handle members 1 and 2 are open and the jaw is positioned inwardly of the extension 6, as shown in Fig. 1. The cylindrical member 15 is then insertedv in the recess 7, and the jaw proper is moved laterally relative to the extension to force the member into the recess until the rib 16 of the jaw is aligned with the channel 8. The jaw proper is thenturned on the cylindrical member as a pivot until the rib 16 enters the channel 8, the rib 17 at the same time entering the channel 9. When both jaws have been applied as described, the closing of the handles forces the ribs 16 into wedging cooperation with the walls of the channels 8, and the jaws become in effect fixed parts of the tool. The removal of the jaws when desired is merely a reversal of the above described operation, the movements necessary to accomplish such being obvious.
It is apparent that the operative face of the jaw, so far as the work to be performed is concerned, may be of course of any form, a different form being illustrated in Fig. 4.
I claim:
1. In combination with a tool of the plier type having integral extensions formed with cylindrical recesses and with channels above said recesses, removable jaws having extensions capable of engagement with said recesses, by relative lateral movement of the first mentioned extensions and jaws, and ribs to cooperate with said channels.
2. In combination with a tool of the plier type having integral extensions formed with cylindrical recesses and with channels above said recesses, removable jaws having extensions capable of engagement with said recesses by relative lateral movement of the first mentioned extensions and jaws and ribs to cooperate with said channels, the cooperation of certain of the ribs and channels being a wedging cooperation.
3. In combination with a tool of the plier type having integral extensions formed with cylindrical recesses and with angularly-related channels above said recesses, removable jaws having extensions cooperating with said recesses through relative lateral movement of the first mentioned extensions and jaws, and ribs to cooperate with said channels.
4. A tool of the plier type having a jaw receiving extension formed in the inner face with a recess opening through said face and with a channel extending at right angles to the recess, and a jaw adapted for removable connection with said extension and having a projection capable of seating in said recess but incapable of passing through the recess opening in the inner face of the extension, said jaw having a rib tofit in said channel.
5. A tool of the plier type having a jaw receiving extension formed in the inner face with a recess opening through said face and with a channel extending at right angles to the recess, and a jaw adapted for removable connection with said extension and having a projection capable of seating in said recess but incapable of passing through the recess opening in the inner face of the extension, said jaw having a rib to fit in said channel, the rib and channel having a wedging cooperation.
In testimony whereof I affix my signature.
PETER M. BUR-MAN.
