. l I 4 Claims.

This invention relates to the broad class of can openers and has more particular reference to a multiple purpose kitchen and household implement which is characterized by can opening means and is provided with extra facilities usable in other capacities.

An object of the invention is to provide a simple, practical and efficient implement of a type embodying an open loop-like frame and an extensible, retractible and reversible tool or implement carried by said frame.

In carrying out the principles of the invention, I contemplate using an elongated substantially U-shaped frame formed from scrap metal, the outer free end'portions of the limbs of said frame being especially designed to accommodate a multiple purposed implement which is slidably and detachably mounted in place.

I Another object of the invention is to form a hook on the terminal of one of the free end portions or limbs of said frame which hook co-acts with'the adjacent implement in providing an appropriate bottle cap remover.

A further object of the invention, structurally speaking, is to provide a simple implement in barlike form, the same being rectilinearly straight, fashioned at one end with an offset pointed can punch and having the opposite end formed into a bit which may be used either as a screw-driver or for prying can lids loose for easy removal purposes.

Novelty is also predicated upon a handle forming frame having substantially parallel and closely spaced limb portions, these being mechanically connected through the medium of headed rivets and said rivets serving as guide and retention elements for the extensible and retractible multiple purposed implements.

Additional novelty is predicated upon a detachable U-shaped clip and a detent therefor, said clip serving to embrace co-acting limb portions and a portion of said implement to render the overall structure sufliciently strong and stable for reliable use.

Other objects, features and advantages of the invention will become more readily apparent from the following description and the accompanying illustrative drawings.

In the drawings, wherein like numerals are employed to designate like parts throughout the same:

Figure 1 is an elevational view, partly in section, of a so-called can opener constructed in accordance with the principles of the present invention;

Figure 2 is a view in elevation and at right angles to Figure 1;

Figure 3 is a view based on Figure 1 and showing the manner in which the extensible and retractible tool or implement is retracted into the handle frame for compactness and convenience; and,

' Figure 4 is an enlarged cross sectional view on the plane of the line 4-4 of Figure 2, looking in v the direction of the arrows. 7.

Referring now to the drawings by distinguishing'reference numerals, it will be seen that the frame unit or means is denoted, generally speaking, by the numeral 6, the same being formed from strap metal and said strap being bent intermediate its ends and upon itself as at 1 into general U-shaped form. The limb portions are denoted by the numeraIsB and 9, the limb 8 being somewhat longer than the limb 9 and terminating in a hook I!) which serves, in a manner to be hereinafter described, as a bottle cap remover. The free end portion of thelimb 9 is inwardly offset as at I I to provide a rectilinearly straight portion l2. The limb 8 is inwardly ofiset by lateral bending as at l3 and is again bent laterally and inwardly as at [4 to provide a rectilinearly straight portion 15, this being disposed in close spaced parallelism to the limb portion l2. The outer ends of the portions l2 and 15 are provided with spaced rivets l6 which serve to assemble the parts and which also serve to accommodate the projectible, retractible and reversible tool IT. This part H, in the main, is a rectilinearly straight bar which is rectangular in cross sectional form and which slides between" the parts l2 and ii of the limbs and which is, when in operation, held in placebetween the spaced rivets l6. One end of the tool is laterally offset and pointed as at I8 to provide a can punch. The opposite end is suitably tapered andformed as at l9 to provide a bit which may be used either as a screw-driver or as a lid prying and lifting element.

I provide a sleeve 20 which is slidable on the tool and said sleeve serves'as a carrier for a cutting blade 2I, said blade being lateral to the sleeve and being carried by an arm 22 which is mounted in the sleeve and which has one end hooked and clenchedagainst the sleeve as at 23 for assembling and retention purposes. The sleeve and blade may be adjusted, as a unit, in relation to the can punch I8 in an obvious manner.

I next call attention to a U-clip 24 which is applicable and detachable as shown in dotted lines in Figure 3. This clip fits over the limb portions-l2 and I5, as shown, and also embraces the edge portions of the tool to provide the desired stability in relationship of parts when set up for use. The bight portion of the clip is provided with a keeper notch 25 to accommodate the hooked end of aspring detent or latch 26.

- The numeral 2l designates a cork-screw which is pivoted or otherwise secured to the limb 8 as indicated at 28. This is an optionably usable feature.

It is obvious that the tool may be slid in or out,

the same being. shown projected to an cm i position in Figure 1,"and being retracted to an in" folded position in Figure 3. Not only is the tool retractible and projectible in relation to the frame 6, but it is also reversible. That is to say. the tool may be bodily slipped out from between the pins I6 and limb portions l2 and 15 andthen ,portion of one of said limbs, a pair of studs piercing a portion of said latch and adjacent portions of said limbs and securing the latch in place and turned through a half circle and reinserted for reversible use.

As before mentioned, the hook Ill, when used in conjunction with the bar 01' @001 H may be employed as a de-capper.

Comparing Figure 3 with Figure 1, it will be seen that the tool means I! has been turned andfully reversed. That'i's to say, in Figure 1,,we,

see the it s c part of said tool means,"

projectedwiththe bit l9 clipped andsituated. within the confines of the U-fi'ame 61,, the punch ldand can cutting blad'ei I- having beeriextended for use, during which. said punch is] punched. through and anchored in the can top-and the blade is raked around the marginal edge and. forced in and down tomake the desired circular cut}. Ofcourse, said tool' means can be shoved. bodily up and'into thef'rame when out of use (as shown in dotted line s). if and when the user cle-v sires to so retractand store it in acompact dut-of-the-way position. In Figure, 3 said tool means is pictured in full lines in a corresponding.

out-of-tl'ie-way. position. However, it should be.

noted that in the latter figure, it has been reversed, and to do this, the user simply slips and. withdraws said tool from the framed (Figure 1) and. then turns it upside down. and inserts the bit end l9 between the limb-ends I2 and l5,.an-

gling said end i9 betweenthe. assembling and re'.

taining studs or rivets l6, and. then backs the punch-end IS into the frame 6. "During this changeover procedure, and to install said bit 19 for projection and use, the brace-clip 24 is uns napped from its latch 26 andbodily detached, aiter. which said clip isreplaced.

In respect. to structural features of the inven tiion', fthe reader willv note the. closely spacedandl inter-relatedlimb-ends l2 and l and the pro. vision of the studs [6 connecting said. ends and readyingsame for insertion and retention of the tool means. Further, the provision of the. clip 24,"wh'ich is saddledv in place and held by the snap-latch 2B is noteworthy, for said clip embraces both the limb-ends and tool-bar I1 and effects a non-twisting and stabilized association, of elements. In fact,,the studs. 16 and limb-ends alone do not well serve to adequately assemble and retain the tool means l1. Hence,,the need for said clip or some equivalent sustaining and strengthening means.

careful consideration of the foregoing description in conjunction with the invention as illustra'ted in the drawings will enable'the readerto obtain a clear understanding and impression of the alleged features of merit and novelty sufficient-to clarify the construction of the invention' as hereinafter claimed.

Minor changes in shape, size, materials and ,the limbs together, said studs being disposed in spaced parallelism, a tool bar lodged but slidable between said limbs and slidable between the studs, and a U-shaped clip removably fitted over 'one limb and having its end portions straddling both limbs toassist in maintaining the tool bar against displacement, said latch being releasahlyconnectedwith saidclip;
