SAFETY-RAZOR.

Specification of Letters Patent.

Patented May 3, 1910.

Application led January 2, 1909. Serial No. 470,521.

A To all 'whom 'it may concern:

Be it known that I, HENRY A. KinsEL- HORST, a citizen of the United States7 and resident of St. Louis, Missouri, have invented cert-ain new and useful Improvements in Safety-Razors, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof. Y l

My invention relates to a safety razor, the

i, object of my invention being to provide a simple holder adapted to receive a thm narrow blade having a cutting edge and which blade is clamped between the edges of a pair in general use a comparatively wide blade is made use of, and which form of blade contains considerable material which is wasted4 when the blades are thrown away after havlng become dull. I propose to form a blade from a very thin and narrow piece of plain sheet steel, devoid of lugs, notches or apertures, and which is only of such size as to have sufficient body to be gripped between a pair of plates.

In practice I have, demonstrated that practical blades can be formed of sheet metal having a thickness of approximately three one-thousandths of an inch, an inch and a half in length, and one-eighth of an inch in width, and thus it will be readily seen that the blades can be very cheaply produced, as compared to safety razor blades of the present construction.

To the bove pur oses, my invention consists in certain nove features of construction and arrangement of parts hereinafter de- -scribed claimed and shown inthe accompanying rawings, in which:

Figure 1 is an elevation of va safety razor of my improved construction; Fig. 2 is an end elevation lookin at the head of the razor; Fig. 3 is an en arged vertical section taken longitudinally through the center of a razor of my improved construction; Fig. 4 is a vertical section taken through the head of the razor and showing the plates swung into open positions; Fig. 5 is a vertical section taken on the line 5 5 of Fig. 4; Fig. 6 is a cross section taken on the line 6-6 of Fig. 3;.Fig. '7 is an elevationof a sheet of metal from which razor blades are formed; Fig. 8 is an elevation of a narrow strip of material from which the razor blades may be formed; Fig. 9 is a plan view of a guard or packing strip on which the razor blades are packed; and Fig. 10 is an enlarged cross section taken on the line 10-10 of Fig. 9.

Referring by numerals to the accompanying drawings; l designates the handle of the holder of my improved razor, which handle is in tubular form and provided at one end with a head 2, in the form of a transversely curved plate, the lower edge of which is provided with a series of teeth 3, which form-a guard to prevent the razor-blade from cutting the skin while the razor is in use.

Formed in the face of the plate 2, imme-` diately above the teeth 3, is a longitudinally disposed shallow groove 4.

Hinged to the top of the plate 21, is a blade holding plate', which is curved transversely to conform to the curvature of the plate 2, and said plate-5 is of such thickness as that it is perfectly rigid; and formed in the 1nner face of this plate 5, and at the free edge thereof, is a continuous groove 6, which receives the narrow razor blade hereinafter described. The. plate 5 is of such width as that this groove 6 occupies a position d1- rectly opposite theshallow groove 4 when the plate 5 is swung downward in front of said plate 2.

Seated in the lower portion of the plate and in the wall immediately in front of the groove 6, is a series of disks 7, of soft iron, which perform the function of armatures in order that theJ razor blades, which are magnetized, will be held in the groove 6 by magnetism when Seatedptherein, thus preventing the blades from dropping from the holder when the parts are being assembled and adjusted for use. Y

Formed integral with the central portion of the plate 5, and projecting inward therefrom. is a lug 8,` in which is formed a notch 9. the inner end of which is extended laterally at right angles as designated b v 10.

Hinged to the upper, end of the plate 2,

y between said plate-and the f length of the ing formed one edge of which is -said ribbon or tape is separated into suitable It is the inten'- v A tween the plates C and sembled, and

plate 5, is the upper end. of a thin flexible plate 11, in the center of which is formed an opening 12, and formed on this plate adjacent its free edge is a longitudinally disposed rib 13, which when the razor is assembled for use occupies the position in -the shallow groove 4, thus maintaining Vsaid plate 11 rigidlybe- The blades 14 utilizedl in my'irn'proved razor are formed from a thin sheet of steel and said blades being equal in length to the plates 2, 5 and 11, and of such width as to occupy and fill the groove 6, and the sharpened edge of said blade projectin beyond the edges of the plates 5 and 11 an occupying a position immediately in front of the teeth 3 forming the guard.

he means utilized for clamping the plates 5 and 1'1 together and maintaining the same against'the curved plate 2, comprises a rod 15, the forward end of which is provided with a pair of oppositely arranged lugs 16, which are adapted to enter the notch 9 and pass lnto the laterally disposed ends 10 thereof when the parts of the razor are asformed integral with the rear end of this rod 15 is a screw threaded head 17 which is adapted to receive a cylindrical nut 18.

InV Fig. 7 I have shown the thin narrow blades as being formed from a plate of sheet steel and where this arrangement is carried outone edge of the' metal plate is ground and sharpened, after which the material at the end of the plate is cut olf on a 'transverse line to form the narrow blade.

The blades are magnetized either before or after manufacture, in order that they will, by the action of the soft metal disks 7 when positioned in the groove 6, and thus said blades are held in said groove until the drawn/.together to rigidly clamp the blade.

In Flg. 8 I have shown the blades as bei from a narrow ribbon or tape, sharpened, after which lengths to form the blades. tion that the blades utilized in my improved razor are to be formed and sharpened by specially designed machinery, and for this reason and the fact. that very little material 1s required for said blades, the same can e very easily and cheaply produced.

Theblades when packed for sale and delivery are preferably located in narrow strips of corrugated paper as seen in Figs. 9 and10, and in order to maintain the blades on said strip of paper said blades and paper are immersed in suitable liquid, such Aas paralin, which causes the blades to adhere to the paperand also protects said blades a ainst the action of rust due to the presence o moisture. This coating ofv paratlin, or

magnetism, adhere to plates 5 and 11 are the like, fects the is extremely thin and in nowise'af i When a blade is to be inserted in the i holder for use, the forward end of the rod 13 is disengaged from the notches 10 in the lug 8, and the plates 5 and 11 are now free to swing outward awa from the plate 2, as shown in Fig. 4, ne of the thin narrow blades is now positioned in the groove 6, and said blade is held therein by magnetic action between said l blade and the disks 7, and the thin resilient plate 11 is now swung againstA the plate 5, or in such a position as that the free edge of said plate 11 bears Aagainst the under side of the blade seated in the groove. Both plates 5 and 11 are now swung downward onto the plat 2, and thus the lug 8 is moved into a positio -within the forward end of the handle 1. The forward end of the rod 15 is now inserted in the notch 9 in the lug 8, after which said rod is slightly rot-ated to cause the` lugs 16 to enter the notches 10, and the nut 18 is now manipulated on the threaded head 17 in such a manner as to tighten against the end of the handle 1,

and consequently draw the plates 5 and 11 tightly against the plate 2, which action rigidly grips the blade 14 held between the edges of sald plates 5 and 11.

A. razor of m improved construction is very simple and inexpensive, can beveasily assembled, taken apart and cleaned, and utilizes blades which can be very easily and cheaply produced.
