BOTTLE OPENER Filed Nov. 4. 1927 I gmcmtcwz W/LL/AM E HARE/517A],

3 Guam 1 Patented Dec. 10, 1929 UNITED STATES PATENT OFFICE BOTTLE OPENER- Application filed November 4, 1927. Serial No. 231,019.

This invention relates to improvements in bottle opening apparatus, and more particularly to such as are especially designed for cooperation and coordination with other tools and implements commonly employed as an adjunct to activities incident to the opening of bottles.

Among the objects in view is the production of a simple, and inexpensive construction of sturdy capacity and efiective operation, capable of easy and ready application and renewal relative to the instrument or tool with which it is associated in operation.

Other objects will in part hereinafter become apparent and in part be stated.

The invention contemplates the utilization of a tool, such as an ice-pick, as an operating handle or carrier for a jaw designed and especially well adapted for removing caps of the crimped type from bottles, the formation of the parts being such as to insure against slipping or other displacement of or injury to the jaw during use.

The invention also includes, in such a structure, a jaw of substantial thickness pendent from its carrier and having an approximately chisel-shaped biting edge extending preferably for the full thickness of the jaw and insuring effective engagement with the margin of a crimped cap to be removed.

The invention also includes in a device of the character indicated, a jaw formed of side plates terminating in outstanding end portions shaped into a hook, and further includes a sleeve carrying said aw.

In greater detail, the invention includes a body formed of sheet metal shaped to the form of a sleeve adapted to snugly surround a supporting rod, side portions of the sheet metal being extended edgewise and formed into a hook.

The invention comprises additionally certain other novel constructions, combinations and arrangements of parts as hereinafter specified and claimed.

In the accompanying drawings,

Figure 1 is a view in side elevation of a structure embodying the features of the pres ent invention.

Figure 2 is an inverted plan view thereof.

Figure 3 is an end view thereof.

Referring to the drawings by numerals, 1 indicates a handle of any appropriate or acceptable form for a tool 2 of the spike, rod '55 or. shank type, such as a well known form of ice-pick.

Snugly surrounding the rod or shank 2 is a sleeve 3 having a jaw'4 located, proportioned and designed for engagement with the "00 edge of a crimped cap for a bottle for lifting the same from the neck of the bottle. As clearly seen in Figures 2 and 3, the sleeve 3 is preferably formed from a sheet of metal rolled or otherwise formed to its tubular shape, and the jaw 4L ismade up of portions of the sheet extending from the sides of one terminus of the sleeve 3, the sides being indicated at 5, 5, and diverging, as clearly seen in Figure 3, to their outer extremity where portions of the material are bent laterally at 6, 6, to meet, as clearly seen in Figure 2, said lateral portions forming a hook as the terminus of the jaw 4, and being preferably beveled to produce a relatively sharp edge 7 7 5 exposed in position to engage the crimped edge of the bottle cap to be removed. The chisel-like edge 7 insures a firm grip against the cap, and the width and taper of the sides 5 insure a jaw 4 of suflicient sturdiness and '80 stability to readily withstand the stresses to which the parts are to be subjected, even though the parts are formed of relatively thin metal.

The operation of the structure is fairly obvious, consisting, as is usual with the ordinary bottle opener for caps of the character indicated, of applying the sleeve 3 across the upper surface of the 'cap to be removed with the hook forming the terminus of jaw '90 4: located with the edge 7 in engagement with a portion of the edge of the crimped cap. The operator then lifts upwardly on the handle 1, and thus disconnects the cap from its engagement with the neck of the bottle. The reactive force incident to the stress thus exerted against the inturned tabs 6 is readily taken up by the side plates 2. The sleeve 3 end of handle 1 presented toward shank 2, and the sleeve being of relativly thin sheet metal formed up to the contour described is adapted to be sprung slightly as it is brought to its seat against the end of the handle 1, so that the sleeve snugly grips the shank 2. Also, the sleeve is preferably tapered slightly to correspond with the taper of the shank 2,

and thus insure a snug engagement for the full length of the sleeve, Which gives a maximum bearing for the distribution of stresses.

What is claimed is:

A bottle opener comprising a sleeve formed of a sheet of material, the-said material extending from parts of the sleeve to form spaced side plates and said side plates terminating in laterally bent tabs projecting to produce a hook of substantial Width designed to engage the edge of a bottle cap.

In testimony whereof I aflix my signature.

WILLIAM E. HARRISON.
