Specification of Letters Patent.

Patented Sept. 24, 1907.

Application filed April 17,1905- Serial No. 255,872-

To all whom it may concern:

-Be it known that I, DANIEL W. GAGE, a'citizen of the United States of America, and aresidentoi Carnthe initial cost, providing few er parts tocare for, and

materially increasing the efficiency of the device.

It is an improvement upon another application of mine, filed Nov. 18, 1904, Ser. No. 233,323, and also upon the invention shown and" described in Letters ram No. 765,885, dated Jul 2 1904.

It consists in certain nov 1 features of construction and arran ement of parts which willbe readily understood by. reference to the description of the drawings and to the claims to be hereinafter given.

Of the drawings: Figure lrepresents an elevation of one side of a safety razor embodying my invention.

Figv 2 represents the opposite side thereof. Fig. 3

represents a transverse section of the same drawn to an enlarged scale, the cutting plane being on line 3-3 on Fig. 1 and looking toward the handle. Fig. 4' represents a longitudinal section of the same on line 4-4 on Fig. 1, thehandlebeing removed. Fig. 5 represents an inside elevation of the guard plate. Fig. 6 represents a transverse section of same drawn to an enlarged scale, on line 6-6 on Fig. 5. Fig. Trepresents an elevation of the hollow handle the upper part of the same being broken in section. Fig. 8 represents a plan view of the same. Fig. 9 represents an inside view of the clamping plate. Fig. 10 represents a transverse section of the same on line 10-10 on Fig. 9

drawn to an enlarged scale, and Fig. 11 represents a side elevation of the cutting blade.

Similar characters designate like parts thgpughout the several figures of the drawings.

In the drawings, 10 is a guard plate each edge of which is provided with a series of teeth 11. To the inner face of said plate 10 is secured a member 12 the lower end of which is provided with an extension which cooperates with another extension on the lower end of the guard plate 10 to form a suitable shank 13. To strengthen this shank and stiffen it there is interposed between the extensions of theplates 10 and 12 a plate v 14. The shank 13 is made hexagonal, octagonal or 18 slightly below the npper edge of the plate 12. The plate 12 extending across the lower end ofthe recess .16 forms a socket '19 adapted to receive the tongue 20- formed upon the lower end of the clamping plate 21 the upper end of which is provided with an overturned lip 22 which fits into the notch 23 in the upper end of the guard plate 10, for the purpose of clamping firmly between said plates l0 2l, the cutting'blades 24 extending in opposite directions on either side of the axis of the handle.

The blades 24 are each provided with a cutting edge 25 and are bent near the middle so that the cutting or forward portion of said blade is in a different but parallel plane to the rear portion 26 thereof sothat between said rear portion 26 and the cutting edge portion 25 there is a stiffening web 27 which strengthens the blade and prevents it from being bent longitudinally.

As the blades 24 are made-of very thin steel which could be easily bent and as it isdesirable to have the cutting edge perfectly straight, this offset in the blade, stiffening the same, forms a very important feature in this invention. The depressed portion 26 of the blades are made to fit the depression 16 in the guard plate 10 and one depressed portion overlaps the other the edge of the inner blade abutting one Wall of the depression 16, thereby registering the blade while the rear edge of the'other abuts against the rear wall of. said web 27 as clearly shown in Fig. 3 of the drawings.

The clamping plate 21 is made of thin metal and is bent so as to form a projection 28 which fits between the rear walls of the web 27 to prevent lateral movement of said blades 24. The outer edges of the plate 21 are solncwhat beveled asshown in Figs. 3 and 10.

at the same time securing a device in which the blades may be rigidly held in position for effective operation without pins, notches, or other usual holding and po' sitioning devices. H

It is believed that'from the foregoing the operation of the invention will be thoroughly understood without further description. I

Having thus described my invention, I claim: 1. Ina safety razor, the combination of a guard plate provided with a handle engaging shank and a transverse shoulder adjacent to said shank extending substantially from edge to edge of said guard plate, a removable blade one end of whichabuts said shoulder and extends toward iii thc lind of said guard plate, and means for clampingsald blade to said guard plate.

2. In a safety razor, the combination ot-a guard plate provided with a handle engaging shank and a transverse shoulder 'adjacent to said shank eiteuding substantially fromfodge to edge of said guard plate, a removable blade one end of which abuts said shoulder and extends toward. the end of said guardplate, and means cooperating with said guard plate for clamping said blade thereto.

,3. In a safety razor, the combination of a guard plate provided with a handle engaging shank extending longitudinally thereof and a transverse shoulder adjacent to saidshank extending substantially from edge to edge of said guard plate, a removable blade one end of which abuts said shoulder and extends toward the end of said guard plate, and means cooperating with said guard plate for clamping said blade thereto.

4. In -a sai'ety razor, the combination of a guard plate provided with a handle engaging shank ektending' longitudinally thereof and a longitudinal shoulder and a trans "shoulder, :1' removable blade cooperating with said shoulders, and means for locking said plni'cs together to clamp said blade in position.

6. In a safety razor, the combination of a guard plate provided with a longitudinal recess, two blades provided with depressed portions overlapping each other, and a clamping plate provided with a projection cooperating with said depressed portion of said blades.

7. in a safety razor, the (-ombination'of a. guard plate provided with 11 longitudinal recess andhaving a socket in one end and a notch in the opposite end, removable blades provided with shouldered portions adapted to fit said recess, a clamping plate provided with a tongue to notch thereof.

8. In a safety razor, the combination of a guard plate provided with a longitudinal recess and having a socket in one end, removable-blades provided with shouldered portions adapted to fit into, said recess,a clamping plate provided with a tongue to fit said socket in the guard plate, and means for connecting" the opposite ends of said clamping plate and said 'guard plate together.

i). in a safety razor the combination of a guard plate provided with a sdcket in one end and a clamping plate provided with a tongue to fit said socket, one of said plates having a longitudinal recess therein, two blades overlapping each other and provided with depressed porprovided with a handle-engaging shank, a transverse shoul der, a socket extending inward from said shoulder, a depression extending: longitudinally thereof, and a, notch in the end opposite to said handleengaging shank a removable blade one end of which abuts said shoulder and which is providedwith a longitudinal projection fitting said depression; and a clamping plate one end of which abuts said shoulder adapted to retain said blade in posi tion provided with a tongue at one end fitting said socket and at the opposite end with an overturned lip adapted. to engage said notch.
