RAZOR BLADE SHARPENING DEVICE I Filed June 20, 1930 W H Wm WM Qua-fan J wE/IEILOR ATTORNEYS.
Patented June 9, 1936 PATENT OFFICE RAZOR BLADE SHARPENING. DEVICE Hugh De Haven, New Canaan, Conn., assignor to De Haven Razor Corporation, a corporation of Delaware Application June 20, 1930, Serial No. 462,519
17 Claims. (Cl; 51-158) This invention relates to a razor blade sharpening device and the general object of the invention is such a device into which the razor and the blade may be placed and which may be operated to sharpen the edge of the blade.
Another object of the invention is such a device which may be used as a box in which the razor may be kept when it is not being used for shaving andin which the blade may be sharpened before-the razor is taken out of the box.
A further object of the invention is such a device which may be used as a container for the razor and which cooperates with the razor to sharpen the blade when the said container is shaken.
Other objects and features of the invention will more fully appear from the following claims taken in conjunction with the description and accompanying drawings which, however, must be considered as merely illustrating and in no way limiting the invention to the embodiment shown and described;
The drawing illustrates in plan and section views selected forms of construction adapted for the sharpening device and embody the broad principles of the invention.
In the drawing:
Fig. 1 is a plan view of one form of the blade sharpening device with the container open so that Q9 the razor may be seen; 7
Fig. 2 is a vertical longitudinal section through the device shown in Fig. 1, with the container closed;
Fig. 3 is a section through a slightly different form of blade sharpening device, with the container closed;
Fig. 4 is a plan view of the body of the container shown in Fig. 3, with the razor in sharpening position;
Fig. 5 is a side elevation of the razor shown in Fig. 2, with the head of the razor in section; and
Fig. 6 is a side elevation of the razor shown in Fig. 3, with the head of the razor in section.
Only such parts of the device are shown as are necessary to illustrate the broad principles of the invention, it being understood that various forms of razor and various forms of containers, sharpening elements and other parts for holding the razor and the blade may be used.
The device which is shown consists primarily of a container adapted to receive th razor and blade and in which they are mounted for reciprocation relative to the sharpening element. The reciprocation may be obtained in any suitable manner but in the particular forms of the device which are illustrated herein the razor and blade are loosely mounted within the container so that by shaking the container or tilting it from end to end the reciprocation of the blade and razor is accomplished due to the weight of the razor. Within the container are one or more sharpening elements with which the edge of the blade may contact so. that as the razor and blade reciprocate relatively thereto, the edge of the blade moves back and forth relatively to and in contact with the sharpening elements to sharpen the edge of the blade.
In the form of device and razor which are illustrated in Figs. 1 2 and 5, the razor consists of a handle I, a head 2 and a blade holder 3 Within which the blade 4 is held. The base plate 5 of the razor head is preferably formed with guardteeth 6 on the front side. The blade holder or cap 3 is mounted on a shaft '1 having a flat side 8 so that the blade holder 3 either will remain in the position shown in Fig. 2 or will be pressed toward the base plate 5 to hold the blade against the guard teeth 6. This action is obtained by making the blade holder or cap 3 of spring material and forming the parts as shown in Figs. 2 and 5 so that the blade holder is held in the position shown in Fig. 2 by the fiat side 9 of the blade holder bearing against the flat side 8 of the plate, and, the blade holder or cap 3 is pressed toward the base plate 5 when the parts are in the position shown in Fig. 5, by the tendency of the upper part [0 of the cap to lie flatly against the flat side 8 of the shaft 1. The blade is held within the blade holder by a clip ll which is part of the blade holder and which grips the backing I2 of the blade.
The container for the razor has a body l3 and a cover I4 which fit together, as is shown in Fig. 2. Within the container is a sharpening element I4 which is so placed that when the razor and blade are inserted within the container the blade is in contact with the sharpening element. The sharpening element I4 is also so placed that when the razor and blade move or reciprocate within the container, the edge of the blade moves over the sharpening element to sharpen the blade. One position of the sharpening element is illustrated in Fig. 2, in which the sharpening element I4 is on a part l5 of the container in such a position that it contacts with the edge of the blade when the razor is placed within the container with the cap in its open position, The handle of the razor is supported at the end l6 of the container in a suitable slot or groove so that the razor and blade may reciprocate lengthwise of the container (that is from the left to the right, or from the right to the left of Fig. 2) which causes the edge of the blade to reciprocate in contact with the sharpening element I4. It will thus be seen that in the form of device shown in Figs. 1 and 2, the razor is not held within the container in fixed position and may easily be reciprocatecl by shaking the container. The distance between the sides l8 of the container is preferably somewhat greater than the width of the razor and the slot I1 is somewhat greater than the diameter of the handle so that the razor may have a side reciprocating motion in addition to the longitudinal reciprocating motion. The lower end H] of the handle should be smooth in order to permit the razor to move readily within the container and. an end plate 20 is provided within the container to serve as a stop to prevent the end of the handle from wearin through the end of the container. The length of the longitudinal reciprocating stroke is determined by the end H) of the handle contacting with the plate 20 when the razor moves to the right of Fig. 2 and by the plate 5 or side arms of the razor head contacting with a stop plate 2| when the razor moves to the left of Fig. 2.
The sharpening element I4 is preferably provided with a raised portion 22 having a form substantially similar to that shown in Fig. 1, from which it will be seen that when the razor and the blade are within the container there is a three-point support to enable the blade to contact evenly with the sharpening element, that is the handle of the razor is supported within the groove I1 and the blade is supported on the two wings of the crescent or angular shaped raised portion of the sharpening element. This enables the blade to bear evenly against the raised portion 22 of the sharpening element, with the result that all portions of the blade will be evenly sharpened as the blade reciprocates in contact with the sharpening elements; for instance, even if the blade is slightly warped the edge of the blade will contact evenly with the raised portion 22 of the sharpening element, the edges 23 of the sharpening element being somewhat rounded to enable the edge of the blade to evenly contact therewith. The length of stroke which the razor may have when reciprocated should be so regulated by the proper placing of the plate 2| with regard to the plate 2|] that all portions of the edge of the blade contact with the raised portion 22 of the sharpening element so that the edge of the blade is sharpened throughout its full length.
The weight of the razor will hold the blade in contact with the sharpening element but in order to give a greater pressure of the blade edge against the sharpening element, a spring 24 may be fastened within the. container to force the razor toward the sharpening element. The spring 24 is preferably a leaf-spring fastened to the cover of the container by the fasteners 25 so that the free end of the spring presses the razor toward the sharpening plate with a yielding pressure which varies as the razor reciprocates, that is as the razor moves toward the left of Fig. 2 the pressure of the spring forcing the blade against the sharpening element decreases. A ball or other suitable friction decreasing element 26 is preferably interposed between the cap 3 of the razor and the spring 24. The ball 26 may conveniently be held in place on the cap 3 by means of suitable keepers 21 which may be struck up from the cap.
The tail or thumb-piece 28 of the cap 3, by which the cap may be moved into either of the positions shown in Fig. 2 or Fig. 5, is preferably so formed that when the cap is in the position shown in Fig. 2, the end of the finger piece rests against the upper part of the razor handle, a groove or slot 29 being formed in the base plate 5 of the head of the razor in order to enable the finger piece to contact with the handle. This holds the parts as a fairly rigid structure when the razor is within the container with the parts in sharpening position.
To sharpen the razor shown in Figs. 1, 2 and 5 it is only necessary to reciprocate the razor by shaking the box. This reciprocates the edge of the blade in contact with the sharpening element l4. To sharpen the other side of the blade the container is opened, the razor is removed and the blade is then taken out of the blade holder 3 and turned over so that said other side of the blade is in position to contact with the sharpening element l4. The razor is then returned to the box, the cover is put on and the box is again shaken to sharpen said other side of the blade.
The razor blade sharpening device shown in Figs. 3, 4 and 6 is designed so that a plurality of sharpening elements 30 and 3| may be used. The sharpening element 30 is mounted in one part of the device, for instance in the body l3 of the container, and the other sharpening element 3| is mounted in another part of the device which may conveniently be the cover H! of the container. The edge of the blade is held in contact with the sharpening element 30 by the weight of the razor when the body of the container is lowermost but it will readily be seen that if the container is turned over so that the cover I4 is lowermost, the edge of the blade will contact with the sharpening element 3|. This provides a convenient way of sharpening both sides of the edge of the blade without removing either the blade or the razor from the container and without removing the blade from the razor. The sharpening elements 30 and 3| are preferably spaced and the edge of the blade may be brought into contact with either one of them, as is desired. If the sharpening elements 39 and 3| have the same sharpening characteristics, that is, if they are of the same material and equally smooth, etc., each side of the blade may be sharpened to the same extent by holding the container so that first one side of the blade and then the other side contacts with the sharpening elements and reciprocating the blade relatively to the sharpening elements; but the different sharpening elements 30 and 3| may have different sharpening characteristics, that is the sharpening element 30 may be rather rough to grind the blade edge rather than polish it, whereas the sharpening element 3| may have a different characteristic and may be rather smooth to polish the edge of the blade rather than grind it, but both sharpening elements are preferably of material of such a hardness that the edge of the blade may reciprocate in contact with them without nicking either the blade edge or the sharpening elements. From the previous description it will be seen that when the sharpening elements 39 and 3| have the same characteristics it is necessary only to hold the container as shown in Fig. 3 and then shake it in such a way as to cause the edge of the blade to reciprocate in contact with the sharpening element 30, and to sharpen the other side of the blade it is necessary only to turn the container over to bring the other side of the blade edge into contact with the sharpening element 3| and then to shake the container in such a way as to cause the blade to reciprocate in contact with the sharpening element 3 I. If the sharpening element is rather rough so that it has more of a grinding action than a polishing action on the blade edge, the container may be shaken to cause the reciprocation of the edge of the blade in contact with the element 30 to grind the blade edge. The container is then opened and the razor is turned over so that the other side of the blade edge is in contact with the grinding surface 30, whereupon the container may be shaken to grind the other side of the blade edge. Without removing the razor from the container, the container may be turned over so that the side of the blade which was first ground rests against the sharpening element 3! which has more of a polishing characteristic than a grinding characteristic. The container may then be shaken (with the cover l4 lowermost) tocause the reciprocation of the blade edge relative to and in contact with the polishing element 30. The container may then be opened and the razor again turned over to bring the other side of the blade edge in contact with the polishing element 3| and the container may again be shaken to polish the second side of the blade. It will thus be seen that the blade edge may be ground and polished on both sides in a relatively simple manner without removing the blade from the razor.
In the form of sharpening device shown in Figs. 3 and 4 the razor and blade also have a three-point suspension, that is the handle of the razor is supported at 32 or 33, depending upon which side of the container is lowermost, and the edge of the blade is supported on the crescent or angular shaped raised portion 22 of one or the other of the sharpening elements 30 and 3|. This is in order to enable the edge of the blade to adjust itself for even contact with the sharpening elements. The length of stroke of reciprocation may be determined by any suitable stops. For this purpose the handle of the razor may be provided with a slot 34, and a pin may project from the container in a position to enter the slot when the razor is in sharpening position. The engagement of the pin and either end of the slot determines the length of the sharpening stroke. The length of stroke of reciprocation should be such that the edge of the blade contacts with all of the raised portion 22 of the sharpening elements so that the blade is sharpened throughout its entire length, but the stroke should not be 1 long enough to enable the edge of the blade to hit the end of the container, which would dull the blade edge.
The razor which may be used in this form of sharpening device is also of simplified construction. The blade holder may have the two blade gripping arms 38 and 31 so spaced that the blade may be slipped between them and from the sides of the blade holder the pins 38 extend for mounting the blade and blade holder in the head of the razor. The rear of the blade holder extends at 39 to be held either in the position shown in Fig. 3 or the position shown in Fig. 6 by detents 40 and M, or any similar device which will accomplish the same result. If desired, the blade and blade holder may be a unitary structure and sold as a unit, as are some of the familiar razor blades now on the market.
The pins 38 may be on the sides 42 of the razor head, which may be of spring material so that the sides 42 may be spread apart to permit the pins erably has a socket at its free end to fit exactly the rear 39 of the blade holder so as to hold the blade as shown in Fig. 3, but the socket onthe free end of the detent 40 is preferably so curved that'when the blade is in the position shown in Fig. 6, the rear portion 39 of the blade holder has not fully seated in the socket. This causes the detent 40 to continually press the blade against the guard teeth 6 to prevent any looseness of the blade when the razor is being used for shaving.
By the word across appearing in the claims, applicant intends to define the relative movement of the blade and sharpening element whereby there is a component of motion along a line from the blade edge toward the body of the blade as distinguished from the movement solely lengthwise of or parallel to the blade edge.
Although a particular and preferred form of the invention has been described, it is recognized that many various modifications may be made and it is therefore desired that the invention be construed as broadly as the claims, taken in conjunction with the prior art, may allow.
