Oscar A. R. M. Schmidt, of Louisville, Kentucky. Razor.
No. 860,829. Specification of Letters Patent. Patented July 23, 1907.
Application filed March 29, 1906. Serial No. 308,718

To all whom it may concern:

Be it known that I, Oscar A. R. M. Schmidt, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Razors; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in razors and the like, and more particularly to the handles therefor, and the pivotal connections between the handles and the blades.

The object of the invention is to improve and simplify the construction and operation of devices of this character and thereby render, the same more durable and less expensive.

A further object is to provide a pivotal connection for devices of this character, which may be quickly adjusted and tightened.

With the above and other objects in view, the invention consists in certain novel features of construction, combination and arrangement of parts, as will be hereinafter more fully described, and particularly, pointed out in the appended claims.

In the accompanying drawings,—Figure 1 is a side elevation of my improved razor, with the blade in an open position; Fig. 2 is a longitudinal sectional view through the same, taken on the plane indicated by the line 2—2 of Fig. 1; Fig. 3 is a transverse sectional view, taken on the plane indicated by the line 3—3 of Fig. 1; and Fig. 4 is a perspective view of one of the bearing blocks for the pivot screw.

Referring to the drawings by numeral, 1 denotes a razor blade, of any desired form and construction, and 2 denotes my improved handle for the same, which has at one of its ends my improved pivotal connection 3. The handle 2 is preferably, and as shown, formed from a single strip of aluminium or other suitable metal, by properly shaping it and then bending it upon itself, as shown at 4, to provide the two similar side pieces or bars 5 between which the blade 1 folds. In the spaced ends of the side pieces or bars 5 are formed transverse openings 6, preferably of square or polygonal form and “having their side walls tapered outwardly, as clearly shown in Figs. 2 and 3. These openings 6 are adapted to receive similarly-shaped bearing blocks 7, through which a pivot screw 8 passes, for the purpose of pivotally mounting the blade 1 between said side pieces. These blocks or bearings 7 have their sides tapered or beveled, as shown in Fig. 4, and in their outer or larger ends are formed countersinks 9 which are concentric with the openings through which the pivot screw 8 passes. The latter has a cone-shaped head 10 at one end, to seat in one of the countersinks 9, and its other screw-threaded end is adapted to screw into a cone-shaped nut 11 seated in the countersink 9 of the other block or bearing 7, as clearly shown in Fig. 3. It will be observed that by tightening the screw 8, its head and nut will be drawn into said countersink, and the block or bearing 7 will be drawn into the ends of the side pieces or bars 2 of the handle, so that the blade 1 will be firmly clamped in the latter. This construction permits the blade to be quickly and easily tightened or loosened as desired, and removed when it is desired to replace it by another blade or when it is desired to sharpen or repair it.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention, as defined by the appended claims.

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

The herein described razor or the like, comprising the integral, U-shaped handle having the parallel arms provided near their disconnected ends with inwardly tapered openings, the blade having the shank between the disconnected ends of the handle arms, the inwardly-tapered blocks in the openings of the said arms, one of said blocks having an inwardly-tapered countersink, the pivot screw passed through and secured in the said blocks and also passed through the shank of the blade, and the inwardly-tapered nut on said screw in the said countersink of one of said blocks, substantially as specified.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

Oscar A. R. M. Schmidt.
