CAN OPENER.
Patented Aug. 16, 1892.
UNITED STATES PATENT OFFICE.
ALFRED FENTON AND JOHN BARNES, OF LONDON, ENGLAND.
CAN-OPEN ER.
SPECIFICATION formingpart Of Letters Patent No. 480,868, dated August 16, 1892.
Application filed October 20, 1891. Serial No. 409,243. (No model.)
To all whom it may concern.-
Be it known that we, ALFRED FENTON and JOHN BARNES, subjects of the Queen of Great Britain, residing at London, England, have invented a new and ImprovedTin-Oan Opener, of which the following is a specification.
This invention relates to an improved construction of tin-can opener that will enable either a rounded portion of the top of a can to be cut out or the top out right off.
To enable our invention to be properly understood, we will describe the same by aid of the accompanying drawings, in which- Figure 1 is alongitudinal view of the opener complete; Figs. 2 and 3, detached portions of Fig. 1; Fig. 4, a perspective view of the opener in operation.
A is the handle, holding a metal rod having a portion of its length rounded near the handle, as at B, and square for the remaining portion of its length, as at C. On a side of the end is a spike .D, the stem of which is bent round where it is attached to the rod 0 to form a bend. On the square part is a sliding knife preferably carried on a sleeve E. This knife has two blades F G. the latter being turned at right angles to the other.
H is a tin can.
The use and mode of operating our invention are as follows: The spike D is first stabbed through the tin in the center of the top or bottom and the knife F set upon the rod 0 at the requisite distance from the spike, according to the size piece to be cut out. The point of the blade F is then pressed through the tin and the handle forced round, the blade F thereby cutting out a round portion, the spike D holding the end of the opener to the center of the tin like a universal joint. If the piece is desired not to be out clean out, the spike D enables the cut portion to be readily turned back. It will be understood that during the cutting the can must be held by the hand sufficiently firm to allow the cutting to take place. The operation above described is illustrated at Fig. 4. If it is desired to cut the top off the can completely, the sleeve E is dropped down to the round part B and turned round to bring the knife G to the side of the rod to be in a line with the spike D, which is then stabbed through the center of top and the point of the knife G pressed through the side of the can and the opener turned round, as has been described. It is found in practice that the knife is better carried upon a sleeve, such as E, and that this does not require any set-screw or other means to secure it while the
