CAN-OPEN ER.

SPECIFICATION forming part of Letters Patent No. 4="('0,'710, dated March 15, 1892. Application filed .Tune 25, 1891. Serial No. 397,469. (No model.)

To (ZZZ whom it may concern:

Be it known that I, WARREN H. SHAY, of Toledo, county of Lucas, and State of Ohio, have invented certain new and useful Improvements in a Compound Tool; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the-same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form part of this specification.

Myinvention relates to a compound tool, and has for its object to provide a handle to which may be attached a Wire for forming a can wrench or holder and with provision for attaching a cutter to form a can-opener.

A further object is to form the pivotal center of the knife-lever adjustable radially.

A further object is to provide for a radial adjustment of the knife.

The invention consists in the parts and combination of parts hereinafter described, and pointed out in the claims.

In the drawings, Figure 1 is a plan view of a combined can wrench or holder and canopener. Fig. 2 is a perspective view of the handle and adjustable center for the canopener pivot. Fig. 3 is a plan view of the clamping-wire. Fig. 4 is a side elevation of the knife-lever. Fig. 5 is an enlarged transverse sectional view of the knife-lever and knife-bar, showing the knife in full lines; and Fig.6 is a longitudinal vertical section through the center of the handle with the front half removed.

1 designates the handle, formed with a curved projection 2 to bear against the can, and a hook projection- 3, which is engaged with loop end 4 of a clamping-wire 5. The clamping-wire is bent in circular form and has an end portion 6 running parallel with the body of handle 1, whereby the handle and wire may be grasped in the hand, and by forcing the Wire toward the handle the area of the circle is decreased, thereby impinging the wire upon the euter surface of the can and forcing the same frictionally against the curved projection 2 of the handle suffithreaded end 8 of a pin 9, the head of the pin being enlarged to prevent the same from pass- I ing through the slot as :the pin is introduced from the bottom side of the handle. The front cross-bar 10 of the handle, which extends across the slot, is formed with a rib 11,there being, preferably, an intermediate cross-bar 12 to prevent the metal on each side of the slot from springing when the handle is grasped.

l3 designates a longitudin all y-movable pivot-bar formed with a downwardly-projecting guide-pin 14 at the rear end, which enters slot 7 and moves freely therein, and also with serrations 15 upon the front end, into which the rib 11 enters when the bar is properly adjusted, the bar being held in adjustment by pin 9, which passes through a perforation formed in the bar by means of a nut 15, run upon the projecting end and bearing upon the upper side of the bar. The outer end of the pivot-bar is formed with a perforation 16 to receive a pivot-pin 17, projecting vertically from the outer end of a cutter-lever 18. Lever 18 has a fiat body portion 19,having a slot 20 formed longitudinally thereof, through which is passed a screw-threaded pin 21, secured to a knife 22, there being a thumb-nut23 run upon pin 21 to holdthe same to any desired adjustment upon the knife-lever. The outer end of the knife-lever is provided with ahandle 24, by which to operate the same.

In operation, if it is desired to unscrew the top of a can, loop 4 of clamping-wire 5 is engaged with hook 3 of the handle, the wire is caused to embrace the top of the can, when the handle and end 6 of the wire are grasped, and the top is firmly held by the wrench while unscrewing the same.

To convert the tool into acan-opener-that is, for tin cans in which fruit, &c., is hermetically sealed-the pivot-bar 13 is extended to a degree to cause the perforation therein to coincide with the center of the can. Pin 17 of lever 18 is now introduced into the perforation and knife 22 is adjusted by means of the thumb-screw, so that it will enter the top of the can near the margin,when by grasping the handle. of the lever and forcing the knife through the top of the can,and then moving the knife-lever circumferentially with respect to its pivot, a circular disk is cut either par tially or entirely from the top, as it is only necessary in order to cut the top entirely from the can to release the frictional hold upon the can and move the wrench or holder to another position upon the can to complete the out.

It will be understood from the foregoing description that the device is not only simple and inexpensive but that it is adaptable to cans of various sizes by reason of the expansibility or eontractibility of the are of a circle described by the wire and the adjustability of the pivot-bar and knife.

In some forms of tools where the cans are of uniform diameter I may cast the pivot bar integral with the handle and form the knife either solid with or adj ustable upon the knifelever.

lVhat I claim is- 1. In a compound tool, a handle formed with an integral curved projection to bear against the can and an oppositely-disposed curved projection havingareversibly-curved hook. in combination with a clamping-wire formed with a loop end to engage the hook,

said wire having a circular portion to embrace the can and an end portion in parallel relation with the body of the handle.

2. In a compound tool, a handle formed with oppositely-disposed arms, a clampingwire connected with one arm, having a body portion to embrace an object and an end portion in substantially parallel relation with the body of the handle, a bar connected with the handle, having an end portion projecting beyond the arm of the handle, and a lever pivotally connected with the bar and carrying a cutter.

3. In a compound tool, a handle formed With oppositely-disposed arms, a clampingwire connected with one arm,having a body portion to embrace an object and an end portion in substantially parallel relation with the body of the handle, a bar ad justably eon- 5o nected with the handle, having an end portion projecting beyond the arm of the handle, and a lever pivotally connected with the bar and carrying an adjustable cutter.

I11 testimony that I claim the foregoing as my own I hereby aflix my signature in presence of two witnesses.

WARREN ll. SHAY.
