Specification of Letters Patent.

- Patented Dec. 29, 1908.

- Application filed April 4, 1908. Serial No. 425,262.

To all whom it may concern; Be it known that I, EDWARD H. SMITH, a citizen of the United States, residin at Ceof Wayne and tate of West Vii" inia, have invented certain new and usefuFImprovements in Can-Openers, of which the following is a specification.

This invention relates to that class of devices known as combination tools and especially to those of the integral type.

An ob'ect of this invention is to form a tool of this character that may readily be applied'to cut the tops of cans of various types.

Another object is to form the blade with such a curvature that when disdposed atdifferent angles 1t will be adapte straight or in a circular line.

A still further object is to provide' a tool of this type having grooves or recesses that will guide the blade during the performance of its functions. g

' An object attained by-this invention is the provision of a can opening portion which to cut in a may be especially adapted to either square.

or round cansby'a slight change in the di-' rection of its application to the can.-

An important object of this invention is to provi e a plurality of tools in one structure occupying a minimumamount of space and arranged conveniently for operation by handle.

parent from the following description, and it will be understood-that changes in the specific structure shown and described may be made within the scope of the claim and any suitable materials may be used without depaptin from the spirit of the invention.

11 t specification, and in which like numerals of reference indicate similar parts in the sevside elevation of the tool, Fig. 2 is a bottom plan view of the same, Fig. 3 is an end elevation, Fig. 4 shows the device applied to a cylindrical can, Fig. 5 shows the device applied to can.

Referring to the drawings, 10 designates a handle having an'aperture 11 which may be used for supporting the tool when it is desired The handle 10is gradually reduced in width until it approaches the depending lug 12 where the handle 10 continues diagonally and oppositely of the lug to form an offset portion 13. The upper plane as the curvature of e drawings forming a portion of this a rectangular face 14 of the offset portion 13 is in a straight plane until it reaches the stepped portions 15 formed intermediate of sald offset portion 13. A T shaped u wardly extending portion 16 is formed at t offset portion. ,13, said portion '16 being sharpened on its upper surface edge as shown at 17 in Fig. 1. .Forwardly of the portion 16 the offset portion is directed inwardly again as shown at 20. The rearwardly extending arm 18 of said portion 16 is ste ped on its under faceto correspond with t e steps 15 formed on the upper surface 14 of the offset 13. The under surface of the forward extension 19 of said ortion 16 is disposed at an angle equal to tl ie'downward he outer extremity of the ofiset portion 13 is extended into a cutting blade 21 which is of concavo-convex .formation for a purpose hereinafter described. A recess 22, so formed as to have one face in substantially the same the cutting blade 21 is formed behind and below said blade 21, as shown. Su porting one face of said recess 22 is a. epending member being grooved in its under and forward faces as at 24 and having notches 25 and 26 formed in the rear face thereof. The under surface 27 of the ofiset portion 13. is formed substantially into an arc of a circle between the notch 26 and the depending. lug 12. A depending portion 28 is formed in the under surface 27 immediately under the ste s 15. A corkscrew 29 is pivotally mounted in a depression 30 of the handle 10. By suitable spring tension the corkscrew 29 is held in a closed position in said groove 30. The use of the device is as follows: The blade 21 is used as a can opener. When the top of a circular can is to be cut the edge or rim of the can is engaged-in the recess 22. If on the other hand a can with a rectangular top is to be opened the groove 24 is used in conjunction with said blade 21. The groove 24 and the recess 22 serve as guides for the direction of the blade 21 while in operation. It is also found that by the use of the 'recess 22 or groove 24 very rapid manipulation may be effected. The notch 25 is especially adapted to effect the openi of can, bottle, or jar tops of the self seaing variety while the notch 26' is intended to open the crimped caps of bottles. The portion 16 and edge 17 thereof are to be used as a meat tenderer while the arms l8and 19 of said portion 16 slope of the 'up er surface 20 of the offset 13.

are used conjunctively with steps 15 and sureled at its upper end, and a depending memface 20 as anut and pipe Wrench respectively. ber carried by said oil'set portion having a The corkscrew 2-9 being pivoted in the handle forward beveled edge registered with the bev- 10 of the whole device, the whole device eled edge of said blade for the purpose of 15 5 serving as a handle to the said corkscrew 29. guiding said blade during operation.
