Henry J. Gaisman, of New York, N.Y. Safety-Razor
SPECIFICATION forming part of Letters Patent 759,262, dated May 10, 1904. Application filed April 6, 1903. Serial No. 151,253. (No Model.)

To all whom it may concern:

Be it known that I, Henry J. Gaisman, a citizen of the United States, and a resident of New York city, borough of Manhattan, New York, have invented certain new and useful Improvements in Safety-Razors, of which the following is a specification.

In the class of razors commonly called “safety-razors” it is customary, so far as am aware, when the blade is to be sharpened to remove the same from its holder and place it in a separate handle or machine, so that the blade may be sharpened upon a strop. This removal of the blade from the razor-frame and its replacement necessitates considerable loss of time while shaving and involves considerable trouble and exposes the blade to accident and injury.

The object of my invention, therefore, is to provide a safety-razor wherein the blade can remain connected with its holder in the frame both for shaving and while being sharpened upon a strop, whereby time, annoyance, and injury are saved, as well as the cost of extra appliances ordinarily required for stropping the blade.

In carrying out my invention I provide a suitable frame having a blade-guard with a pivotally-supported blade and means carried by the frame and connected with the blade adapted to coact with a strop to rock the blade, whereby when the strop is held taut and the frame is reciprocated along the strop the action of the strop upon said means will cause the blade to swing or oscillate and bear upon the surface of the strop, so that the opposite sides of the edge of the blade will alternately be caused to bear upon and be drawn along the surface of the strop to sharpen the blade. Provision is also made for holding or locking the blade firmly in position with its edge adjacent to the guard for shaving purposes and whereby when the blade is unlocked it will be free to oscillate for stropping purposes, and by preference I provide means to maintain the edge of the blade away from the guard when unlocked.

The invention also comprises the novel details of improvement that will be more fully hereinafter explained and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part hereof, wherein—

Figure 1 is a perspective view of a razor embodying my invention shown in position ready for use in shaving. Fig. 2 is a similar view showing the blade in position to be stropped. Fig. 3 is a face view of the razor, enlarged, looking from the side opposite Fig. 1, the blade being removed and its holder turned to the front position. Fig. 4 is a section on the line 4 4 in Fig. 3, showing the blade in position; and Fig. 5 is a longitudinal section substantially on the line 5 5 in Fig. 4 looking in the direction of the arrows.

Similar numerals of reference indicate corresponding parts in the several views.

In the drawings the main frame of the razor is indicated generally at 1 and is shown having a base part 1a and uprights or standards 1b 1c at the ends.

At 2 is indicated a suitable handle which may be attached to the frame in suitable manner, as by means of a threaded stem 3, extending from the frame.

At 4 is indicated a guard adjacent or contiguous to which the cutting edge of the blade 5 is adapted to rest during the shaving operation. While said guard may be arranged and supported in any well-known manner, I have shown the same provided with lugs 4a at its ends entering slots 6 in the uprights 1b 1c, screws 7 passing through lugs 4b near the ends of the guard and entering threaded lugs 1d on the frame, serving to adjustably support the guard with respect to the razor edge.

Pivotally supported between the uprights 1c 1b of the frame is a movable member or roller 8, shown in Fig. 5 as provided with pivots or gudgeons 8a, journaled in bearings in said uprights. Said member or roller 8 is adapted to bear against a strop, (indicated at 9 in dotted lines in Fig. 4,) and by preference said roller is fluted or toothed longitudinally, whereby it will be caused to move or rock when pressed against and moved along the strop. The blade may be supported to rock in suitable manner.

At 10 is indicated a holder for the blade 5, which is shown in the form of a tubular shaft or sleeve provided with clips 11, adapted to grasp the blade and hold the same firmly. These clips are shown in the form of jaws, preferably having a spring-gripping action, and the blade is adapted to be slipped between the clips in the longitudinal direction of the holder, the blade preferably bearing against a shoulder 12 at the inner end of the holder and being adapted to spring behind a lip 13 at the opposite end of the holder to keep the blade from longitudinal movement. By lifting the blade slightly it may be drawn over the lip 13 for removal from the holder.

The blade-holder 10 is shown pivotally supported upon a rod or shaft 15, secured to the upright or standard 1b and projecting parallel with and located above the roller 8, a space being provided between said roller and holder to receive the strop 9. As shown, the upright 1c is shorter than the upright 1b, the rod or shaft 14 being free at its outer end, whereby a strop may be slipped edgewise between the roller and the holder; but of course the upright 1c could be carried outwardly corresponding to 1b and the rod 14 supported by both uprights. The blade-holder 10 is connected with the member or roller 8 so as to be rocked or oscillated thereby, and to this end I have shown a gear 15, secured to holder 10 and meshing with a pinion 16, that is journaled upon a pin 17, secured to upright 1b, said pinion meshing with the teeth or flutings of the roller 8; but, if preferred, a separate gear could be secured to roller 8 for the same purpose. By this means as the roller 8 is rocked the blade-holder 10 will be correspondingly rocked or oscillated in the same direction as the roller.

At 1x is indicated a shield connected with rod 14 and pin 17, gears 15 16 being located between said shield and upright 1d to keep the edge of the strop from engaging the gears.

To hold the blade 5 in the shaving or cutting position, as shown in Fig. 1, I provide a handle or arm 18, that is secured to member or roller 8, as to its pivot 8a, and the handle 18 is shown located on the exterior of upright 1b and adapted to oscillate with roller 8.

At 19 is indicated a latch pivotally supported upon frame 1, as at 20, and adapted to swing outwardly to come in contact with and lock handle 18. As indicated in Fig. 1, latch 19 is shown provided with a socket 19a to receive the end or edge 18a of handle or arm 18 to prevent spontaneous displacement of the latter. The latch may have spring-tension with respect to arm 18. The relation of these parts is such that when blade 5 is swung against guard 4 the handle 18 will be moved in position to be engaged by latch 19, as in Fig. 1, in which position all the parts will be held or locked firmly together. When blade 5 is to be oscillated for stropping purposes, the latch 19 is moved away from handle or arm 18 and the parts are free to move, as in Fig. 2.

By preference I provide means for maintaining the blade 5 in a substantially vertical position when not held against the guard. To this end I have shown a torsion-spring 21, that passes through a bore 8c in roller 8 and is connected at one end to the handle 18, as by a pin 22, or to the roller, and at the other end said spring is shown suitably bent and connected with the upright 1c. The position of the parts is such that when there is no tension upon spring 21 it will tend to hold arm 18 in such position that, through the gearing, blade 5 will be held vertically, (see Fig. 2,) and when the blade is swung down in either direction the spring will be put under tension. It is obvious, however, that the spring can be otherwise arranged to hold blade 5 away from guard 4 when not locked against the same.

My improved safety-razor may be operated as follows: When it is desired to shave with the razor, the blade is swung down against the guard and held in such position by the latch 19 and can then be used in well-known manner. When the blade is to be stropped, latch 19 is moved away from arm 18 and spring 21 causes blade 5 to swing upwardly, and thereupon a strop is inserted between roller 8 and the blade and held taut, said roller being firmly pressed against the strop. The razor is next reciprocated along the strop, and by the contact of the strop with roller 8 the latter is rocked back and forth, whereby, through the gearing, the blade will be swung from side to side, as indicated by the arrows in Fig. 4, thereby causing the edge of the blade to bear upon the strop for sharpening such edge. The arrangement of the parts is such that the edge of the blade will project behind and follow the frame as the latter travels along the strop. For instance, if the razor be moved to the left in Fig. 4 roller 8 will be caused by the strop to rotate in the direction of the arrow a, and the gearing will cause the blade to be swung behind the frame to drag on the strop, the roller then sliding along the strop and holding the blade edge in contact therewith, and when the pressure is relieved from roller 8 blade 5 will rise from the strop, and when the frame is moved in the reverse direction the blade will be swung over to its dotted position, (shown in Fig. 5,) so that its edge again follows behind the frame. Thus each time the direction of movement of the razor-frame is altered the blade 5 will be swung over in the reverse direction. This swinging of the blade into position behind the frame prevents the edge of the blade from injuring the strop and becoming dulled. Of course the frame can be held stationary and the strop reciprocated upon roller 8 with the same effect of rocking the blade upon the strop.

It will be understood that by means of my improvements it is not necessary to remove the blade from the frame, but that while the blade remains in the frame it can be readily sharpened, and then it is merely necessary to swing the blade down against the guard and to lock it in the cutting position. This saves the necessity of removing the blade from a holder, applying it to a different holder or machine for stropping, then removing it from the latter and placing it in the razor-frame, and avoids danger of injuring the blade, the advantages of which will be obvious.

While I have illustrated and described what I consider an advantageous and practical embodiment of my invention, it will be understood that the various details and arrangements shown may be modified and changes made without departing from the spirit of my invention.
