' Applicationfiled June 25,1915; seria1nt ;-3e;191p I Y the city of Louisville, county of Jefferson,
and State of Kentucky, have invented a certain new and useful Improvement in Can- Openers, of which the following is a specilication.
This invention relates to an improvement in that class of implements, used for obtaining access to containers formed of thin sheet metal, known as can-openers.
An object of this invention is to provide an implement of the class referred to which may be used by an unskilled person with a minimum of eflort and a maximum of safety.
A further object is the production of a' tool of the class described which will be economical to manufacture and which will be efiicient and durable in .service.
With the foregoing and other objects in view the invention consists of the novel construction illustrated in the accompanying drawing which forms a part of this specification.
In the drawing wherein similar reference characters designate like parts in the several views, Figure 1, is a perspective view of a can and an opener showing the method of operation; Fig. 2, a perspective view of my improved opener: Fig. 3, a perspective view of a blade: Fig. 4:, a sectional view on line 2-2 of Fig. 2: Fig. 5, a plan of a blank from which the blade is formed.
Referring to the drawing the reference numeral 10 designates a handle which may be constructed of any suitable material and of such shape as will best conform to the hand. The blade 11 is secured to, or connected with, the handle by suitable means, and extends beyond the lower end thereof. As illustrated the handle is formed of wood and has two plane parallel surfaces 12, 13, and is rounded at the top 14- to fit the palm of the hand. The edges slope down to the lower end 15 which is of reduced area, compared with the top. One of the edges 16 is slightly rounded transversely while the other 17 is a plane surface. The blade comprises a web l8 having flanges -19 and 20 extended from the edges thereof and is provided with an oblique cut ting edge 21 which is continued on the flanges. In the embodiment of the invenforation -.23 in the blade.
ti'on illustrated, the bla'deissecured on the v plane edge 17 of the handle, by means ofa screw 22 which is passed through a per- The blade is secured on the handle in such relationship thereto that the heel 2 1- of the cutting edge, on the flange 20, lies below the end of the handle such a distance as will allow it to pass through the wall of the container, before the handle comes into contact therewith. Other obvious ways of attaching the blade to the handle will suggest themselves to those skilled in the art, and with a change of material in the handle other methods of at taching the blades will have to be resorted to.
In service the opener is held in the hand, in the same manner as a handle of a screw driver, with the rounded upper end resting against the palm of the hand. The tool is held straight up with the point 25 of the blade resting on the wall of the container a suitable distance from the edge thereof, care being observed to see that the entire cutting edge of the blade will come within the edge of a can, then push the tool straight downward until the lower end of the handle comes into contact with the can, then pull it out. the end of the first out, etc. (See Fig. 1). After a sufficient number of cuts have been made,the severed-portion may be raised with the point of the opener. It will be observed that the handle makes a out which comprises a straight portion 26 and lateral- extensions 27, 28. In making the second and subsequent cuts, the point of the,
blade is inserted in the lateral extension 28 of the previous cut, which serves as a guide for the flange 19 and as a stop to prevent any backward movement of the blade, thereby in securing a cut the full width of the blade at each downward stroke. The shape of the blade allows of the use of a very thin material, sheet metal of approximately .025 of an inch in thickness being preferably used, the flanges serving to give it the requisite stiffness.
It is thought that the many advantages of a can-opener constructed in accordance with the foregoing description may be readily understood, and it will furthermore be evident that changes, variations and modifications may be resorted to without departing from the spirit of the invention, or sacrificing any of its advantages, and I therefore do not wish to re- Start second cut at Qopies of this patent may be obtained for tended at an abrupt angle from said edges, and a handle to which said blade is attached and extends longitudinally therefrom, whereby said blade cuts only on a direct longitudinal thrust the front flange making a lateral incision which serves as a guide and an abutment for the rear flange when making a succeeding cut.
