Application filed'March 24, 1919. Serial No. 284,660.

To all whom it may concern:

I Be it known that I, PERCY C. BROOKS, a citizen of the United States, residing at St. Johnsbury, in the county of Caledonia and State of Vermont, have invented certain new and useful. Improvements in Cutting Implements, of which the followingis a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

"This invention relates to devicesfor utilizing the blades of safety razors for purposes other than shaving.

It is a primary object of the invention to provide a simple and inexpensive holder device whereby blades of the character men,- tioned which have become" dulled and which are then ordinarily discarded can be further utilized as the cutting elements of pocket 'knives for general purposes.

It is a further'object to provide a device such as referred to which "is structurally desirable and functionally advantageous.

Other objects and advantages will be in part mentioned hereinafter in connection with the following description of the accompanying drawing, which illustrates two .typical embodiments of the invention and in Figure 1 is a perspective view of 'a preferred form of blade holding device;

Fig. 2 is a side elevation thereof with one. part removed; v

Fig. 3 is a perspective view of the device folded; h

Fig. 4 is a similar view of one part;

Fig. 5 is a sectional view on the line A'A Fig. 6 is a perspective view of a modified form of the device;

- Fig. 7 is a similar view thereof with the parts foldedtogether'; Fig. 8 is a side elevation; and Fig. 9 is a sectional view on the line B-B of-FigzS. v i

Referring more particularly to F igs.- 1 to 5 of the drawing, there is shown a blade holder of stamped-metal including a handle, 1, a holder 2, these parts being joined by a pivot 3 through their ends, and a removable clamping elemental which fits over the holder 2. The holder 2 is preferably made in two complementary sections which yield- :ably fit together but are capable of separa- 7 major portion thereof grasped within the holder and having only a slight portion of one cutting edgeexposed. As is well known, the Gillette blade is flexible and is provided with spaced apertures between its cutting edges,-and the holder 2 is accordingly provided with similar apertures or indentations 6 on one part and complementary projections or lugs 7 on the other part whereby, upon insertion of the blade, the two holder parts resiliently grip it and the projections.

7 fit through the apertures of the blade to insure correct installation of the latter and [its rigid maintenance in position.

In order further to clamp the blade while, however, permitting its expeditious removal or substitution, there is additionally provided the clamping element 4 having a tubular portion 8 and straight sides 9 pressing together. The clamp 4 is shapedand proportioned to telescope snugly on the holder 2 with the curled bottom edges 10 of the 'latter fitting in the tubular portion'8 of the clamp so that the clamp sides 9 further tend to press together the partsof the holder and thus rigidly grip the blade in position.

. The handle 1 is U-shaped in cross section and open at the edge correspondingto the cutting edge of the blade, so that as the handle and holder are pivotally folded together the latter with the blade fits between thesides of the handle. However, theopen edges of the handle are so located as to engage the shoulders of the clamp 4 above the tubular portion 8, when the parts are folded, with the closed edge of the handle slightly spaced from the blade. By this arrangement, when the device is folded, it occupies a very small space and the cutting e ge of .the blade is efiectively protected and sealed. If desired, and asalso' shown in the draw- .there is provided a washer plate 11 which fits under the head of pivot 3 and has a resilient extension with an inturned' tremity-12 to fit within notch of the handle exa corresponding 1 when the parts are open and to fit within the'notch mentioned and a similarly placed notch in the holder 2 when the parts are folded together to releasabiy latch the device in closed position.

n the formfshown in the remaining figures the holding tively heavy stamped plates 13 between which the blade fits and. which are adapted to beheld together by screws 14: taking through aperturesin one of the plates,

device comprises two rla- I plate.

through the corresponding holes of the blade, and into projections 15 of the other parent that, upon removal of the screws 14, the plates 13 may be sufiiciently spread apart to permit the removal or insertion of the blade. The handle in this instance also is of stamped metal, U-shaped in cross section, but preferably of the configuration shown wherein an internal shoulder 16 is provided so that, when the handle and holder are folded together, the shoulder men-..

It will be noted that in both forms shown the device comprises relatively few parts, which are capable of cheap manufacture from stamped metal, which occupy a minimum space, which are not unattractive, and in which relatively dull blades, though flexible of themselves, may be rigidly held and By this construction itwill be ap-' thus re-enforced with the cutting edges exposed and constituting the cutting edge of the implement. It will be noted, further, that substitution of the blades can be expeditiously effected and that the device as a whole renders possible the utilization for the many practical purposes of a pocketknife of otherwise waste blades.

Having described my invention, what- I claim as new and desire to secure by Letters Patent is: V

A cutting tool of the character described comprising two pivotally connected sections adaptedto be arranged in end to end relation for use, a safety razor blade constituting the cutting element and removably associated with one of said sections, and a resilient element normally associated with the other section and arranged to hold said sections, fixed relatively in either their extended or folded positions, said element being removable from said section.

In testimony whereof I affix my signature, in the presence of two witnesses.
