CAN-OPEN ER.

SPECIFICATION forming part of Letters Patent No. 399,252, dated March l2, 1889.

Application filed December 3,1888. Serial No. 292,452. (No model.)

.To al? 'zt-7mm [t may Concern:

Be it known that I, JOSEPH HYDE FISHER, a citizen of the United States, residing' in Deerfield, in the county of Lake and State of Illinois, have invented a new and useful Irnprovenient in CaiiOpeners, of which the following is a specification.

This invention relates to that Glass oi' Canopeners having' a blade sharpened upon its 1o upper edge and operated in cutting after the manner of a lever of the first order, it being` provided with a handle and a rest or shoulder adapted to find support upon the can and net as a iuleruni, and located between the blade and handle. As heretofore constructed, each time the handle is pressed down the entire blade is apt to be forced up through the tin beingl out, so that after eaeh out il: y escapes from the slit and must be reinserted 2o below the tin preparatory lo the next eut, and unless very much Care is used the opener is liable, when it thus escapes7 to slip and hurt the hands ol the person using` it. To prevent this escape of the opener after each eut, and to retain its point below the tin, is

the object of' niy invention, and sueh object is accomplished by providing the blade upon its severing' side with a blunt or non-Cutting` p point-that is to say, by providingx it upon said side with a cutting-edge throughout a portion ol its length and an unsharpened portion at the point. This unsharpened poi nt, when it eonies in Contact with the under surface of the iin being' severed, stops the eutting' operation and notities the operator that the limit of the cutting stroke has been reached. This oeeurs Without any withdrawal of the point from the can, and as a consequence the positioning' of the blade for the next. eut will consist simply in moving the device forward. XVit-h this blunt point the opener need not be entirely withdrawn from the interior oi' the can until all the severing,l desired is completed.

This and other features of the invention are fully illustrated in the accompanying drawings, wlierein- Figure l, is a side elevation of the canopener complete. Fig. 2 shows the side el the Cutting-blade the reverse of that shown in Fig. l. Fig. 3 is an enlarged plan or edge View of the Cutting-blade, and Figs. l and 5 are enlarged cross-sections thereon at lines 4c I and 5 5 of Fig'. l.

In said drawings, A represents the operating-handle, and B a guide aiiixed thereto and intended to rest against the edge of the can as the cutting proceeds, so that the line of severation may eoni'orin to the outline of the can.

C is a rest or shoulder on the side of the guide, which is intended to bear upon the top surface ol. the ean and forni the. fuleruin upon whieli the opener works or oseillal'es.

l) is the eutting-blade, and maybe secured to thehandlebyriveis d, or in any othersuitable manner. 'ihe cutting-edge oi. this blade is shown at andL extends from e to e?, leaving' beyond e2 a point. E, wliieh, however, is not sharpened so as to be able to sever the tin 'with its upper edge. In praetiee l prefer to leave it ol:` its original thiehi'less, as such thiek ness is su liieient to stop the cutting when the point eoines in eontaet with the tin. Oi'

` course the very extremity of the point is beveled oil' from all sides, so it may serve as a j'punetnriug-point and be capable of being' jabbed through the metal of the ean at starting'. I sometimes bend this point lll laterally, as shown at Fig. il, as thereby I aeeoniplish desirable results. lfor instance, in the ease ot' round cans the extremity olf lhe point will not be cutting' into the side wall oi the can, as would be the ease il it were not deiieeted andthe can were opened on a line innnediately adjoiningx Athe side wall, and. in all styles of cans it permits the eutting' oli' the ean in closer proximity tothe side Wall than would be praetiea-ble Without it.

l. The can-opener, the blade whereof is provided with an uppersharpeued edge, e, anda. point, E, blunt Vupon its upper edge, substantially as set forth.

2. The can-opener consistingl oit' a handle, a blade havin an upper Cutting-edge and a non-severing point, and a shoulder between l the blade and handle adapted te rest upon the blade and handle adapted te Test upon lthe top of the een mld m31; us :L fuleruln, and the top of the can. und fletas a `ulerum7 subn. side guide, substantially as specified. smntially :1s specified. JOSEPH HYDE FISHER.
