RAZOR.

Specification of Letters Patent.

Patented June 22, 1920.

Application filed June 30, 1919. Serial No. 307,652.

To all whom it may concern:

Be it known that I, WILLIAM HARRY BRASIER, a citizen of the United States,residing at Corpus Christi, in the county of Nueces and State of Texas, have invented a new and useful Razor, of which the following is a specification.

The device forming the subject matter of this application is a/ safety razor, and one object of the invention is to provlde an im-,

plement of the kind mentioned embodying a novel frame for holding a razor blade of any desired sort.

Another object of the invention is to provide a razor blade wherein the vibrations will not be transmitted to the carrying frame, the construction being such that the efficiency of the blade will be enhanced, it being well known that if vibrations of the blade travel into the frame, the-efliciency of the blade is reduced.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combina-' tion and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what isclaimed, changes in the precise embodiment of the invention shown canbe made without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in side elevation, a device constructed in accordance with theinvention; Fig. 2 is an elevation wherein the structure is viewed at right angles to the showing of Fig. 1; Fig. 3 is a plan showing the guard; Fig. 4 is a plan showing the blade in place in the holder; Fig. 5 is a perspective view delineating the holder; Fig. 6 is a perspective view depicting the base portion of the carrying frame; Fig. 7 is a plan of the blade; Fig. 8 is a cross section showing a modified form of blade; Fig. 9 is a a still further modification in the blade; ig. 10 is a cross section wherein a modified form; of blade appears; and Fig. 11 is a transverse section showing the blade construction embodied in a common razor not of the safety type. I

In carrying out the invention as disclosed in Figs. 1 to 6, there is provided a trough- Y shaped base 1 having an elongated transverse slot 2, the base being provided at its edges with supports 3 and 4, the support 3 having an overhanging flange 5, and the support 4 having an overhanging flange 6. a finger 7 is struck outwardly from the flange 5. A the flange 6, and upon either side of the tongue there are eyes 9.

The invention comprises a holder, denoted generally by the numeral 10, the holder including a strip 11 having cross arms 12 adjacent to its ends. The holder includes, further, a strip 14, alined with the strip 11. The strips 14 and 11 may be connected, at one end, for relative movement, in any desired way. In the present instance, but not of necessity, the strips are depicted as connected by an eye l5, having some resiliency, so that the strips 11 and 14 normally tend to swing apart, as shown in Fig. 5. The eye 15 is received between the eyes 9 of the baseportion of the carrying frame, a pivot element 16 being extended through the eyes 15 and 9, the holder, thus, being pivoted at one end to the base portion of the structure. The free ends of the strips 11 and 14 are supplied with openings 17, adapted to coact with the finger 7, in a way to be described hereinafter.

' The invention comprises a guard l8 provided along one edge with relatively short teeth 19, adapted to be used in shaving, the guard being supplied, along its opposite edge, with longer teeth 20, adapted for use in hair cutting. There is a threaded opening 21 in the guard 18. The device includes a handle 22 having a reduced stem 23, there being a shoulder 24 at the inner end of the stem. The extremity of the stem 23 is threaded at 25 to cooperate with the opening 21 in the guard 18.

The numeral 26 designates a blade, which may be of any desired construction.

In practical operation, the blade 26 is placed between the strips 11 and 14 of the holder 10 and" the holder is swung on its pivotal connection 15-169 with the body of the carrying frame, until the cross arms 12 rest on the flanges 5 and 6, and until the strips 14 and 11 are in approximate parallelism,-to grip the blade 26. The finger 7 is engaged in the openings.17, and, thus, the strips 11 and 14are held in gripping relation with respect to the blade 36, the holder 10, as an entity, being prevented spring tongue 8 is struck from V respective flanges from swinging backwardly on the pivotal connection 159-16. The guard 18 is inserted between the supports 3 and 4 and the 5 and 6. The stem 23 of the handle 22 extends through the slot 2 of the base 1, the threaded portion 25 of the stem being received in the opening 21, of the guard 18, the guard thus being bound against the supports 3 and 4. Obviously, by rotating the handle 23 until the shoulder 24 no longer is bound against the central portion of the base 1, the guard 18 may be adjusted transversely, the stem of the guard moving in the slot 2. In this way, the teeth 19 or the teeth 20 of the guard may be adjusted properly with respect to the cutting edges of the blade 26, thereby to facilitate the operation of shaving, or the operation of hair cutting. When the finger 7 is disengaged from the openings 17, the strip 14 tends to swing away from the strip 11, thereby freeing the blade 26. When the finger 7 is disengaged from the openings 17 as aforesaid, the spring tongue 8, bearing against the strip 11, near the pivoting eye 15, tends to swing the strip 11 away from the base 1. The base 1, being of trough-shape, is adapted to receive the lather which is scraped off the face, in shaving. The construction of the device is such that it may be opened readily, for cleaning and for other purposes.

A salient and important feature of the invention remains yet to be discussed, and in this connection it may be stated that the efficiency of a razor blade, so far as cutting is concerned, depends in no small degree upon the vibrations of the blade, the efficiency of the blade as a cutting medium being reduced, if vibrations pass into the carrying frame, whereas, upon the other hand, the efiiciency of the blade is enhanced, if the vibrations are prevented from pass ing into the frame. In order to prevent the vibrations from passing into the frame, as aforesaid, the blade may be constructed variously. Thus, as shown in connection with the blade 26, the blade may have longitudinal slots 27 adjacent to one edge, these slots being disposed in alternating order. Adjacent to its opposite edge, the blade 26 may be corrugated, as shown at 28.

, The blade may be in the form designated by the numeral 29 in Fig. 7 the blade hav ing longitudinal slots 30, adjacent to both of its edges. The blade may be corrugated,

'ter,

as indicated at 31 in Fig. 8 or it may have a trough-like longitudinal rib shown at 32 in Fig. 9. In Fig. 10, the blade is of concave-convex form, as designated by the numeral 33. In any event, the blade is altered mechanically, in some way, so as to prevent thevibrations of the blade from passing into the frame. It is to be observed that the strips 11 and 14 on the holder 10 engage the blade along its longitudinal cenleaving the edge portions of the blade comparatively free for vibration. The end portions of the blade are supported on the cross arms 12:

In Fig. 11, an ordinary razor blade 34% appears, the same having corrugations 35 which prevent the vibrations from passing into the rib at the back of the blade.

Although the blades have been described in considerable detail, it will be understood that the carrying frame shown in Figs. 1, 2, 3 and 4 is adapted to be used in connection with a blade of any desired sort, and that the blades, upon the other hand, may be used with a carrying frame differing from the one above alluded to.

Having thus described the invention, what is claimed is 1. A safety razor comprising a troughshaped base provided at its edges with supports having overhanging flanges; a guard between the supports and the flanges; a holder comprising cooperating superposed parts connected at one end and having free ends, means for pivoting the holder to one support at the place of connection between the parts of the holder; a detachable connection between the free ends of the parts of the holder and the other support; and a handle movably mounted in the base and engagin the guard.

2 X device of the class described, constructed as set forth in claim '1, and further characterized by the provision of spring means carried by the first specified support and cooperating with the holder to swing the free ends of the parts of the holder away from the other support.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.

WILLIAM HARRY BRASIER.
