T11 TAT ARTHUR J. FROGUE, OF KANSAS CITY, MISSOURI.
CAN-OPENER.
Specification of Letters latent.
Patented Feb. 9, 1915.
Application filed April 10, 1914. Serial No. 830,903.
To all whom it may concern:
Be it known that I, ARTHUR J. FROGUE, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented a certain new and useful Improvement in Can-Open ers, of which the following is a specification.
My invention relates to improvements in can openers.
The object of my invention is to provide a can opener which is simple in construction, which is easy to manipulate, which is strong and durable, and which may be readily employed to cut a complete disk from a can.
Other novel features of my invention are hereinafter fully described and claimed.
In the accompanying drawing which illustrates the preferred embodiment of my invention, Figure 1 is a perspective view of my improved can opener shown in the initial or piercing position. Fig. 2 is a vertical sectional view with the members shown in the final position. Fig. 3 is an end elevation with the members shown in an intermediate position. Figs. 4 and 5 are plan views respectively of the two members, with the blades and anchoring projections removed.
Similar reference characters designate similar parts in the different views.
One of the members is provided with a cylindrical body 1, preferably cup-shaped, as shown in Fig. 2, and which is provided at one end with a laterally extending peripheral flange 2, from which laterally extends a handle 8. Secured to the opposite end of the body 1 are one or more anchoring devices having flat bases 4: secured to the body 1 and provided respectively with pointed projections 5, which are adapted to pierce a can, not shown. Each of the projections 5 is preferably undercut at the side which receives the stress or pressure of the can during the cutting operation. The inclined or undercut sides of the projections 5 tend, during the cutting operation to draw the projections farther into the can, thereby holding the can opener from accidental detachment from the can during the cutting operation. The anchoring members just referred to have their bases 4 extending laterally beyond the circular periphery of the body 1, thereby serving with the flange 2 to retain the other member of the can opener in operative relation to the body 1. The other member is provided with a ring 6 from which laterally extends a handle 7 and which is revolubly mounted on the body 1 between the bases 4 and the flange 2.
Secured to the periphery of the ring 6 are one or more cutting blades 8 having pointed ends, and respectively arranged so as to have their points disposed in radial alinement with the points of the projections 5, as shown in Fig. 1. This arrangement of the blades 8 enables them to enter the holes which are made in the can with the projections 5. The latter have their outer sides disposed contiguous to the inner sides of the blades 8 respectively, that is, in case the members are in the initial or piercing position shown in Fig. 1. The outer sides of the projections 5 and the inner sides of the blades 8 are located in a circle concentric with the axis of the two members.
The advance edges of the blades 8 comprising the cutting edges 9 are preferably oblique, and the opposite edges 10 are preferably parallel with the axis of the two members. As shown in the drawing, the blades 8 are slightly less projecting at their points than the projections 5, so as to afford less resistance to the piercing of the can.
In operating my invention, the members are first disposed in the positions shown in Fig. 1. The projections 5 and blades 8 are then forced into the can to be out, after which the handle 7 is forced in the direction indicated by the arrow in Fig. 1. The projections 5 will have their undercut sides engage the can while the edges 9 are cutting a disk therefrom. The handle 7 is turned until the blades 8 are again in radial alinement with the projections 5, at which time a disk will have been cut from the can.
I do not limit my invention to the structure shown and described, as modifications, within the scope of the appended claims, may be made without departing from the spirit of my invention.
Having thus described my invention, what I claim and desire to secure by Letters Patent, is
1. A can opener comprising two members pivoted to each other, one member having a cutting blade, and the other member having two anchoring projections adapted to pierce a can, and having similar sides underout and arranged to receive the stress in the cutting operation.
2. A can opener Comprising two members pivoted to each other, one having a plurality of pointed anchoring projections, each having an undercut side arranged to receive the stress in the cutting operation, the other member having a pointed blade, the blade and one of the projections being so arranged that upon movement of the members to the initial piercing position the blade and said projection will be in radial alinement with each other, with the inner side of one in close relation to the outer side of the other and adapted to enter a hole as p it is being pierced in the can by the other.
8. A can opener comprising two members pivoted to each other, one member having a pointed anchoring projection adapted to pierce a can, the other member having a cut- Gopiesof this patent may be obtained for five cents each, by addressing the ting blade arranged to enter a hole as it is being pierced in the can by said projection, when the two members are moved to a predetermined position.
4. A can opener comprising two members pivoted to each other, one having an anchoring projection, and the other having a cutting blade, said projection and blade being disposed so that, when the two members are moved to a predetermined position, the blade and projection will be in a position such that one will enter a hole as it is being pierced in a can by the other.
In testimony whereof I have signed my name to this specification in presence of two subscribing witnesses.
