R. B. BRYANT RAZOR Filed July 14, l936 2 Sheets-Sheet 2 Patented Aug. 23, 1938 PATENT OFFICE RAZOR Roy B. Bryant, Dallas, Tex. Application July 14, 1936, Serial No. 90,582

6 Claims.

This invention relates to new and useful improvements in razors. One object of the invention is to provide an improved. razor particularly adapted for use with double-edged blades of the usual type but which may also be used with single edged blades.

An important object of the invention is to provide an improved razor consisting of a unitary assembly which is so arranged that the cutting blade is quickly and firmly clamped in cutting position.

Another object of the invention is to provide an improved razor of the one piece type in which the clamping members, for holding the blade in cutting position, are movable with relation to each other, whereby the members may be spaced a substantial distance apart to permit ready insertion or removal of the blade and also to facilitate cleaning of the razor.

A further object of the invention is to provide an improved one piece razor in which one of the clamping members is fixed and the other is movable with relation thereto, said movable member being carried by a slidable means, whereby the usual screw threads or other means for actuating said member are eliminated and said member may be quickly moved into clamping position.

Another object of the invention is to provide an improved razor consisting of a unitary assembly, wherein springs, pivots, and the like are eliminated, whereby operation is simple, wear is reduced, and loss of parts eliminated. A construction designed to carry out the invention will be hereinafter described, together with other features of the invention.

The invention will be more readily understood.

from a reading of the following specification and by reference to the accompanying drawings, in which an example of the invention is shown, and

wherein:

Figure 1 is a side elevation of a razor, constructed in accordance with the invention, 1

Figure 2 is a front elevation of the same,

Figure 3 is a front elevation showing the clampi ing plates separated,

3 of the razor,

Figure 9 is a transverse, vertical, sectional view showing the clamping plates separated,

Figure 10 is a horizontal, cross-sectional view taken on the line I 0-40 of Figure 8,

Figure 11 is a plan view of a blade for use with this form of razor,

Figure 12 is an elevation of a third form of the razor,

Figure 13 is a transverse, vertical, sectional view showing the clamping plates separated, and

Figure 14 is a horizontal, cross-sectional View 1 taken on the lines M-M of Figure 12.

In the drawings, the numeral l0 designates an elongate sleeve which is provided on its upper end with diametrically opposed horizontal arms ll. Vertical guide posts l2 extend upwardly from the outer ends of the horizontal arms ll being at substantially a right angle thereto and in the same vertical plane with the sleeve lfl. A horizontal curved clamping plate l3 has the central portion of its transverse edges secured to the upper end of the posts and forms a horizontal connection therebetween. The width of the clampingplate is greater than the diameter of the sleeve In, as is clearly shown in Figure 1. It is prefer- 25 able that the sleeve, arms, posts and clamping plate be made integral but, if desired, they may be welded or otherwise connected.

An elongate rod I4 is slidably mounted within the bore I0 of the sleeve l0 and has a length 30 greater than the length of the sleeve, whereby its ends project beyond the ends of said sleeve. A cylindrical head 15 is formed on the lower end of the rod l4, and is enlarged, whereby the rod may be readily manipulated by grasping the head with the fingers. A collar I6 is preferably made integral with the upper end of said rod, and a guard plate H, which is curved to conform to curvature of the clamping plate I3, rests on this collar. The guard plate is held in position on the rod M by a headed stud l8 which extends through a central opening l1 provided in the guard plate, and which has its lower end welded or otherwise secured within an axial opening M in the upper end of said rod. It is pointed out that a clearance is provided between the guard plate I! and the head l8 of the stud I8, whereby the rod I4 and stud may be rotated without causing rotation of the guard plate (Figure 6). For maintaining alignment of the guard plate with the clamping plate l3 and also for preventing rotation of said guard plate, vertical guide slots l9 are provided in the central portion of the transverse edges of the guard plate, and said slots receive the vertical posts l2 as shown in Figure 5. The longitudinal edges of the guard plate are provided with a plurality of equally spaced notches Ila to form the usual guard.

A threaded opening I3 is provided in the center of the clamping plate I3 and is in vertical alignment with the head I8 of the stud l8, whereby when the rod I4 is moved upwardly through the sleeve I0, said stud engages the opening and may be screwed thereinto. Since the posts I2 are engaged within the slots ll of the guard plate, it is obvious that upon upward movement said plate is guided into aligned engagement with the clamping plate as shown in Figure 1.

A double-edged razor blade 20 is provided with a central opening 20, and a pair of opposed slots 2I are formed in the ends thereof as shown in Figure '7. The openings and slots are so positioned that when the blade overlies the guard plate I'I, the opening 20' receives the head I8 of the stud I3, while the slots 2I receive the upright posts I2, whereby the blade is restrained from rotation, and upon vertical movement of the guard plate said blade is guided into aligned engagement with the clamping plate.

To place the blade in the razor, assuming that the razor is in the position shown in Figures 3 and 4, the blade is placed between the clamping and guard plates, whereby one of the posts I2 is received within one of the slots 2! provided in the ends of the blade. Each slot is of such depth that the blade may move laterally to one side of the guard plate so that the opposite end of said blade will pass within the opposite upright post I2. After the blade overlies the guard plate, it is moved into alignment therewith, whereby the opening 20 in said blade is engaged over the head I8 of the stud and the slots 2| are engaged by the posts I2 similarly to the guard plate mounting.

The rod I4 is then quickly slid upwardly within the sleeve I0 until the head I8 of the stud is in engagement with the opening I3 in the clamping plate. The rod is then rotated screwing the stud head into the clamping plate opening, and, as the blade is tightly clamped between the upper clamping plate I3 and the lower guard plate I'l, it assumes the curvature of said plates and is in cutting position. To remove the blade it is only necessary to reverse the procedure.

It will be seen that as the rod I4 is readily slidable within the sleeve III the guard plate and blade may be quickly moved in either vertical direction, and as it is preferable that the stud head I8 be provided with coarse threads it will be seen that the rod must be turned through only a minimum number of degrees of rotation to clamp the blade in cutting position. It will be further seen that as the razor is in one piece, manipulation thereof will be facilitated and loss of parts therefrom will be eliminated. The posts I2 are of such height that the guard plate and clamping plate may be separated a substantial distance when the razor is in the open position shown in Figure 3, whereby the blades may be easily inserted or removed and the razor cleaned without difficulty.

A modified form of the invention is shown in Figures 8 to 11, wherein the arms II extend radially outward from the upper end of the sleeve but, instead of being diametrically opposed. as hereinbefore described, extend at an acute angle to each other as shown in Figure 10. Posts I2 extend upwardly from the ends of the arms and due to the disposition of said arms lie in a plane offset from the supporting sleeve. The clamping plate I3a is mounted between the upper ends of said posts as previously described, but in this form the posts join the clamping plate at the corners thereof formed by the transverse edges and one longitudinal edge of said plate as shown in Figures 8 and 9. The guard plate is secured to the rod I4 as has already been described, however, in this form the notches in said guide plate which engage the vertical posts I2 are provided in the corners of said plate to correspond to the position of the posts, as shown. Other structure is the same as has already been described. The

further advantage of this form is the ease with which a blade, such as is shown in Figure 11, may be placed in the razor, as the posts I2 do not interfere due to their position out of the plane of the stud head and rod.

Another form of the invention is clearly illustrated in Figures 12, 13 and 14, wherein the sleeve has its upper portion 33' reduced, as shown, whereby an external annular shoulder 3I is formed. One arm 32, preferably integral, extends radially from the upper end of the sleeve and an upright post 33 extends upwardly from the outer end of said arm in a vertical plane parallel to the plane of the sleeve. A curved clamping plate 34 has the center of one transverse edge fixed to the upper end of the post 33 and overlies the sleeve, its position relative to the sleeve 30 being the same as the position of the clamping plate I3 with relation to the sleeve I0 first described. The sleeve 3!), arm 32, post 33 and plate 34 are preferably made integral, though they may be joined in any suitable manner.

An elongate rod 35 similar to the rod I4 already described is mounted in the same manner and likewise carries a guard plate 38 which is held in position thereon in the manner previously described. One transverse edge of said guard plate is provided with a central notch 38 which engages the vertical post 33, whereby rotation of the guard plate is prevented. A post 4!) depends vertically from the opposite transverse edge of the guard plate and is parallel to and in the same vertical plane with the rod 35 and post 33. A horizontal arm 4| extends inwardly from the lower end of the post 40 and is provided on its inner end with an offset ring 42 which encircles the reduced upper portion 30 of the sleeve as shown in Figures 12 and 13 and is slidable thereon. The length of the post 4!) is such that the ring 42 abuts the underside of the arm 32 when the razor is in the clamping position as shown in Figure 12. The head 39 of the stud 39 engages a threaded opening 34 in the clamping plate 34 and is screwed thereinto as previously described.

It will be seen that when the plates are separated as shown in Figure 13 the ring 42 together with the post 32 engaging the slot 38 in the guard plate serves to guide said plate as it is moved vertically.

To insert a blade in the razor, assuming that the razor is in the open position shown in Figure 13, a blade similar to that shown in Figure '7 is placed over the guard plate in such a manner that one of the slots 2I receives the post 33 and the head 39 of the stud extends through the opening 20 in the blade as hereinbefore described. The rod 35 carrying the guard plate is then moved upwardly until the head 39 of the stud engages the opening 34 at which time the rod is rotated screwing said head into the opening and clamping the blade in cutting position. The length of the rod 35 is such that the head 36 on its lower end abuts the lower end of the sleeve 30 when the razor is in the clamping position shown in Figure 12.

Thus, it will be seen that since the post 40 depends from the guard plate and is moved vertically therewith, when the razor is in the open position the post is out of the way and the blade may be easily inserted without interference therefrom. In this form the razor is also easily cleaned, and since it is unitary in structure loss of parts is eliminated. It is noted that the rod 35 is readily slidable within the sleeve 30 whereby as in the previously described forms the guard plate may be quickly moved into clamping position, and the coarse threads preferably on the stud head 39 necessitates only a minimum rotation of the rod to clamp the blade in cutting position.
