SAFETY-RAZOR.

SPECIFICATION forming part of Letters Patent No. 765,885, dated July 26, 1904.

Application filed April 15. 1904.

To all whom, it may con/cern,.-

Be it known that I, DANIEL WV. GAGE, of Cambridge, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Safety-Razors, of which the following is a specification.

My invention relates to Lsafety-razors; and it consists in certain novel features of construction, arrangement, and combination of parts, which will be readily understood by reference to the description of the accompanying drawings, forming a part of this application, and to the claims hereto appended and in which my invention is clearly pointed out.

Figure l of the drawings represents a side elevation of my impoved safety-razor. Fig. 2 is an end view of the same looking toward the bottom of Fig. l. Fig. 3 is an elevation of the opposite side. Fig. L is a transverse section of the same on line A A on Fig. 3, but drawn to an enlarged scale. Fig. 5 is a side elevation of the V-shaped and toothed guardplate. Fig. 6 is a section' of the same on line B B on Fig. 5. Fig. 7 is an elevation of the outer and hinged clamp-plates opened out fiat. Fig. 3 is an end View of the same looking toward the top of said Fig. 7. Fig. 9 is an elevation of one of the razor-blades. Fig. l() is an end view of the same. Fig. l1 is a side elevation of the slotted tubular section of the handle or holder. Fig. 12 is a front elevation of said slotted tubular section. Fig. 13 is an end view of the same; and Fig. la is a transverse section of the razor-head, showing the parts in position for stropping.

In the drawings, l is the main handle, made tubular in form and having its exterior manysided, as hexagonal or octagonal in cross-section, as shown.

2 is a longitudinally-slotted spring-metal tube having a diameter in its normal condition slightly in excess of the diameter of the bore of the handle-section l, into which it may be readily inserted by slightly contracting' its diameter, by virtue of which and its tendency to expand to its normal diameter sufiicient friction is created to maintain it in the position to which it may be adjusted therein. The slot cut through the side of said spring-tube 2 is in two sections 3 and 4 of about equal Serial No. 203,254. (No model.)

lengths, .but of different widths, as shown in Fig. l2.

A pair of clamp- plates 5 and 6 are hinged together on the pin 7, about which they may be moved to bring them into proper relation to the parts to be interposed between them, as the razor-blades 7 and 8 and the two-leaved or V-shaped and toothed guard 9. Each of the clamp- plates 5 and 6 has formed upon and projecting from its inner face a pair of lugs lO and 11 and has cut through it two perforations l2 and 13. The lugs 10 and ll are formed, preferably, by cutting through said plates on three sides of a rectangle and then bending the metal inclosed by said cuts at right angles to the inner faces of said plates, thereby forming two other perforations 14 and 15, as shown in Figs. 7 and 8. Each razer-blade 7 and 8 has cut through it four perforations 16, two of which receive the lugs l() and l1, projecting from the clamp 5 or 6, which is contiguous thereto, while the other two perforations receive the lugs l0 and ll on the opposite clamp-plate when a single razor-blade only is clamped between said clamp-plates preparatory to stropping the same. One leaf of the \lshaped guard 9 has cut through it two perforations 17, as indicated in full lines in Fig. 5, and the other leaf has formed therein two similar perforations 1S, as indicated in dotted lines in said Fig. 5.

When the several parts are assembled in proper relative positions for use in shaving, the lugs lO and 1l on each clamp-plate project through two of the holes in the contiguous razor-blade and enter corresponding holes in the adjacent leaf of the \lshaped guard 9, and then the hinge-joint portion of the razorhead is inserted in the end of the spring-tube 2 which has the wide slot 3, the edges of which slot 3 press against the outer surfaces of the clamp- plates 5 and 6 to firmly clamp all the parts together.

By this construction of the razor-head with two razor-blades mounted on the outer faces of the V- shaped and toothed guard 9 and firmly clamped thereto by folding the clampplates 5 and 6 into contact therewith and inserting the hinged joint into the spring-tube 2 both razor-blades are held in fixed positions IOO
