Specification of Letters Patent.
Patented Aug. 19,1913.
To all whom it may concern. 4
Be it known that I, ALLEN MORELL, a citizen of the United States, and a resident of Denver, in thecounty of Denver and State of Colorado, have invented a new and Improved Can-Opener, of which the following is a full,- clear, and exact description.
This invention relates to can openers and the particular purpose of the structure described is the production of an article with a new and improved fulcrum and an improved puncturing point, whereby the liability of injury to the operator is materially lessened.
It is also of some importance in the production of articles of this class that the structure be simple, whereby the operation may be efiicient and the cost of manufacture small, and such object has been borne in mind.
Reference is to be had to the accompanying drawin a,
cation, in w ich similar characters of reference denote corresponding parts in all the views, and in-whic Figure 1 1s a perspective view of the can opener in operative relation with the top of a can; Fig. 2 is a side view of the opener; and Fig.3 is a plan view. of the blade showing the fulcrum and the puncturing point.
- The device comprises a handle 1 of any suitable and desirable material and a blade 2,1the blade being provided with a "suitable tang entering the andle, the parts being maintained in such position by means of a ferrule 3. The blade 2 is provided with,
the inclined cutting edge 4, the-forward end of which is adjacent, the puncturing point 5, it being noted that the-forward end por tion of the said edge terminates remote from the puncturing point whereby a portion 5 of substantial width is provided, having edge portions 6, adapted to be entered into a can, if sufiic'ient pressure is applied to the handle; as shown particularlyin Fig, 3 this portion 5 is laterallybent: Adjacent the opposite edge portion of the'bla'de is a fulcrum 7, preferably integral therewith,- it being noted that the-bottom of the fulcrum is brought to a cutti edge 8; this fulcrum is of substantial lengt and extends at right angles to the body of the blade 2, which refdrming part of this specifi-' lation is brought about by bending the blade around the intermediate portion 9 which lies between the fulcrum and the blade proper. If so desired, one edge portion of the blade pointed end '11 thereby resulting, the recess and the pointed end cooperating to form a bottle cap remover.
The puncturing point is passed through the can top in the usual manner, and the opener is used in the manner illustrated in Fig. l; by reason of the sharpened edge of the fulcrum 7, the fulcrum will firmly ongage the material of the can 12, forming notches 13 therein at a succession of points, this engagement between the fulcrum and the can preventing sliding. By reason of the substantial thickness of the portion 5 the blade, however, being prevented from entirely leaving the slot formed therein by reason of the engagement of the said portion 5' with the under side of the top.
Having thus described my invention, I
Patent A can opener made of a single piece of material, comprising a blade having an inclined cutting edge thereon, a fulcrum integral with the blade and adjacent the edge ortion opposite the cuttingedge, the said ulcru'm being twisted at its junction with the blade, lying in aplane at right angles thereto and projecting on opposite sides thereof, the forward portion of the blade being formed as a puncturing point, the said portion being bent whereby it extends angularly from the blade, the said cutting 'ed' e terminating remote from the said point, the said forward portion of the blade between the point and the cutting edge being of substantially the same thickness as the body of the blade. p In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
