.1. TIPERY SAFETY RAZOR March 19, 1935.

Filed Aug. 23, 1933 atented Mar. 19, 1935 UNl T -ED 'STATE PATENT orrioe 1,995,232 SAFETY RAZOR Joseph W. Tipery, New Orleans, La.

Application August 23',

2 Claims.

My invention relates broadly to razors and more particularly to a midget type safety razor.

One of the objects of my invention is to provide a construction of safety razor of midget size which is particularly shaped to. facilitate the use of the razor in removing hair under the armpits.

Another object of my invention is to provide a construction of safety razor having a quadrilateral cutting blade with opposite edges of uneven lengths shaped to enable the razor to be used in confined cutting position. 7

Still another object ofmy invention is to provide a construction of razor having a cutting blade which has the outline of a quadrilateral figure and which may be used in confined or relatively cramped positions.

A further object of my invention is to provide a construction of guard for a safety razor by which a blade of quadrilateral outline may be secured in a predetermined position and prevented from slipping.

A still further object of my invention is to provide a construction of quadrilaterally shaped securing plate for a correspondingly shapedcutting blade having means for preventing endwise' slippage of the cutting blade.

Another object of my invention is to provide a construction of safety razor in which the securing means for the blade is telescopically mount ed in the razor handle and connected with a plate member which extends flush with a pair of abutments at each end of the guard in which the razor blade is mounted.

A still further object of my invention is to provide a construction of safety razor in which the handle is disposed at a convenient angle to the cutting blade to facilitate a cross out instead of a straight drawing cut against the hair for thereby increasing convenience and comfort in shaving,

Other and further objects of my invention reside in the construction of a safety razor as set forth in the specification hereinafter following by reference to the accompanying drawing in which:

Figure 1 is a top plan view of the safety razor constructed in accordance with my invention; Fig. 2 is a front elevation thereof; Fig. 3 is a central vertical longitudinal section on an enlarged scale taken on line is a transverse vertical section on line 4- -4 of Fig. 1; Fig. 5 is a perspective view ponent parts constituting the safety razor; Fig. 6 is a plan view showing a modified form of construction; and Fig. l is a front elevation thereof.

1933, Serial No. 686,447

to the drawing in detail, reference character 1 designates the handle of the safety razor of my invention having an axial bore 2 extending therethrough for a distance slightly morethan one-half. of the length thereof. larged bores 3 and 4 of different diameters are formed in the handle 1 over the remaining lengthof the handle 1. A shoulder 3a interconnects the bore 3 with the bore 2. A shoulder 4a interconnects the bore 4with the bore 3. That is to say, the handle 1 has .an axial bore extending therethrough which increases in diameter in progressive steps. The external surface of the handle 1 is provided with knurled portions 5 disposed at spaced intervals along the length of the 1. The end of the handle 1 extends at an acute angle a to the plane surface of the supporting plate 6. The supporting plate 6 has an aperture '1 therein through which the end of the handle 1 Referring extends for forming a soldered connection with the plate 6, the end of the handlel-terminating fiush with the upper plane surface of the support-- u ing plate 6. The supporting plate 6 has a plane surface having the outline of a quadrilateral fig ure. Theendsof the supporting plate 6 are turned upwardly at 8 and9 forming walls extending normal to the plane surface of the support- I ing plate 6., 8 and 9 are unequal in length and are tapered from a maximum height atthe rear edge 10 of the supporting plate 6 to the front edge 11 thereof which terminates in a guard as shown. The rear edge 10 and the guard 11 are The supporting plate 6 is so shaped that the angles between the vertically extending walls .8 and 9 and the rear edge 10 are obtuse while theangles between the vertically disposed walls 8 and 9 and a peripheral line which includes the extremities of the guard 11, are ac te. A razor blade 20 which corresponds in outline to the supporting plate is adapted to be mounted on the supporting plate 6 and secured in position between the vertically disposed walls 8 and 9 with the cutting edge 22 thereof directly aligned with the guard 11. The razor blade 20 is apertured at 23 with the aperture directly aligning with the bore 2 in the handle 1': The razor blade 20 has edges 22, 26, 28 and 29 of unequal length, the angles between the edge 26 and edges 28 and 29 being obtuse, and the angles between the cutting edge 22 and the edges 28 and 29 being acute.

The securing plate 12 by which the razor blade 20 is maintained in fixed position is tapered in thickness from a rear edge 16 to a front edge 21 with the edges 18 and 19 thereof inclined to fit The enhandle 15 b immediately between the vertically extending walls 8 and 9 of the supporting plate 6. The securing plate 12 is apertured at 14 for receiving the rod member 15 which extends through the bore in the handle 1. That is, rod member 15 passes through the progressively increasing bore in handle 1 throughout the portions 2, 3 and 4. The end of the rod 15 is screw threaded at 30 and is engaged by the screw threaded bushing member 24. The screw threaded bushing member 24 has 2 cyn of reduced diameter indicated into the end of the enlarged bore 4 in handle 1. threaded at 27 to engage the screw threads 30 on the end of rod 15, for securing the rod 15 in position on the handle of the razor. The fact that the handle 1 is disposed at an angle to the supporting plate 6 enables the cutting operation to be effectively in a crosswise direction instead of a direct drawing of the razor blade downwardly in a straight line against the hair. Where it may be desirable to use the razor in straight line operations against a beard the handle 1 may be disposed normal to the supporting plate 6 as shown in the modified form of the razor of my invention illustrated in Figs. 6 and 7.

As shown in Fig. 1, the guard 11. is provided with teeth 11a formed by slots 11b disposed at an angle of substantially 45 to the front line of the guard 11. Hence the teeth impart to the hair a diagonal approach to the edge of the blade, causing a shearing action and thus greatly facilitating the cutting of the hair and positively avoiding any pulling or drawing on each individual strand of the beard. Furthermore, looking at Fig. 4, it will be noted that the extreme bottom edges of the inclined slots 11b between the guard teeth 11a are beveled rearwardly as indicated at 11c, greatly facilitating the drawing of the body of the safety razor across the surfaceto be shaved. There is a distinct coaction between the beveled' top surface 11d and beveled lower face lie of guard teeth 11a. The beveled rear edges of the guard teeth 11a are plainly shown in Fig. 4 in full lines and in dotted lines in Figs. 1 and 6. This is a most important feature of the safety parts to a time-taking lathering more or less messy Bushing 24 is internally screw The razor
