Patented Feb. 18, 1936 UNITED STATES PATENT OFFICE Application January 4, 1934, Serial No. 705,287 Renewed August 10, 1935 1 Claim.

This invention relates to cutters and more particularly to a tin cutter.

An object of this invention is to provide a cutter of this kind which has been particularly 5 designed for use by workers in sheet metal to permit the cutting of the metal in places where the ordinary tin ships or shears cannot be used. Another object of this invention is to provide a cutter of this kind which is exceedingly simple in 10 construction and which is readily sharpened.

The above and various other objects and advantages of this invention will in part be described and in part be understood from the following detailed description of the present pre- 15 ferred embodiment, the same being illustrated in the accompanying drawing wherein:-

Figure 1 is a detail side elevation of a device constructed in accordance with the embodiment of this invention, showing the device in operative 20 position on a piece of sheet metal which is shown in fragmentary form.

Figure 2 is a view similar to Figure 1 but showing the manner in which the cutter operates to cut the metal.

25 Figure 3 is an enlarged sectional view taken on the line 3-3 of Figure 2.

Figure 4 is an enlarged fragmentary side elevation of the cutter.

Figure 5 is a plan View of the cutter on a piece 3 of metal which is shown in fragmentary form.

Referring to the drawing wherein like numerals of reference designate corresponding parts throughout the several views, the numeral I0 designates generally a handle of desired length and thickness which, in the present instance, is constructed in the form of a relatively fiat bar rectangular in transverse section and provided at the inner end thereof with an opening or hole I 3, which permits the device to be supported on a 40 nail or other suitable hanger.

The outer or forward end of the handle II) has integral therewith a cutter blade I I provided with a keen edge I2 which is disposed longitudinally of the handle ID and terminates in a relatively 45 sharp point I4. Disposed opposite from the blade II is a jaw member I provided on its inner edge Wth a convex portion I6 confronting the straight keen edge I2 of the blade II. This convex portion I6 provides a fulcrum which is adapted to engage on the side of the sheet metal opposite from the side engaged by the blade II and acts to permit the rocking movement of the handle I0 so as to shear the metal by means of the blade I2. The inner end of the jaw I5 is preferably disposed in spaced relation to the inner end of the keen edge I2, as at I7, so that the entire length of the blade II may be used in the cutting of the material.

As shown in Figures 1 and 2, the sheet metal designated S is adapted to have the cutting blade II projected through an opening or slot I8 with 6 the blade II on one side of the sheet metal and the jaw I5 on the opposite side with the metal S extending to the inner end I! of the jaw I 5. The handle IIJ may then be raised, as shown in dotted lines in Figure 1, and. this movement will be 10 facilitated by the convex edge portion I6 of the jaw, and this movement will cause the keen edge I2 to shear the metal. The cutter may be rocked either in a vertical or horizontal movement depending on the position of the sheet metal S. By reason of the space between the jaw I5 and the blade II, the keen edge I2 may be readily sharpened as this keen edge has beveled opposite sides. 1

The handle I 0 rearwardly of the blade II is provided with a recessed portion I9 having a bottle decapper 20 projecting thereinto so that the cap of the bottle may be received in the recess I9 and the cap removed by engagement of the projection or decapping lug 20 beneath the edge of the cap and raising of the handle I ll.

As shown in Figure 5, the cutter herein disclosed may be used for cutting circles from a sheet metal S or, if desired, the cutter may be used for straight cutting and can, of course, be used for removal of the tops of metal goods or the like. The handle 5 ll is preferably constructed relatively long so that the desired leverage can be applied to the cutting blade I I to cut the sheet metal of relatively heavy gauge.

It is, of course, understood that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claim.

What is claimed is:

A cutter as set forth comprising an elongated handle substantially rectangular in transverse section, a straight flat cutting blade integral with the forward end of the handle and coplanar therewith, and. a pointed flat jaw member integral with the forward end of the handle and coplanar therewith and disposed in spaced relation to the blade, the line of cutting of the blade being in the line of thrust of the handle, said jaw member having a convex inner edge portion terminating at the rear end thereof in spaced relation to the confronting edge of said blade.
