United States Patent Ofilice HAIR CUTTERS Abraham N. Spaniel, Princeton, N. J., assignor to International Latex Corporation, Dover, Del., a corporation of Delaware V Application January 19, 1955, Serial No. 482,717
Claims. (Cl. 30-31) This invention relates to hair cutters especially adapted for home use for complete hair cutting as well as for trimming the human hair; and more particularly to hair cutters wherein replaceable cutting blades are employed with complete safety as the cutting element.
An object of the invention is to provide a hair cutter adapted to cut short as well as long hair, evenly and smoothly, with barber-like precision.
Another object of the invention is to provide a hair cutter in which clogging of the cutting edge is materially reduced and the cut hair readily freed.
Another object of the invention is to provide a hair cutter which may be readily and economically produced in quantity production.
Still another object is to provide a hair cutter with a double edge cutting blade in fixed position, each edge positioned in a fixed cutting position, one for close cutting, such as for shaving, and the other for shortening the longer hairs.
I accomplish these and other objects and obtain my new results as will be apparent from the device described in the following specification, particularly pointed out in the claims, and illustrated in the accompanying drawing in which:
Fig. 1 is a top plan view of an embodiment.
Fig. 2 is a side elevation of the same.
Fig. 3 is an end view thereof.
Fig. 4 is a transverse cross-sectional view taken at line 4 4 of Fig. 1.
Fig. 5 is a fragmentary longitudinal cross-sectional view taken. at line 5-5 of Fig. 1 with the partspartially assembled.
Fig. 6 is a perspective view of a blade clamp plate forming part of the device, as shown in Figs. 2, 3 and 4.
Figs. 7, 8, 9 and 10 are end elevational views showing various modifications.
Referring to the drawing in greater detail, Fig. 1 illustrates a form of my device in which both the blade holder and cage are fixed against adjustable movement. In this device a double edge blade is essential for successful over-all operation.
Referring more particularly to Figs. 13: a handle, designated as 100, may be conveniently made of flat sheet metal die stamped to suitable shape and formed into a hollow section (Fig. 4) or may be made of plastic. The outer end of the handle stock is formed so as to provide a guard or cage holding portion 101 (Fig. 3) having oppositely disposed longitudinally extending parallel grooves for receiving cage bars 102-403 of a cage generally designated 3d, snugly and frictionally held therein. The cage 3d may comprise the bars 102 and 103 from which the ends of wire ribs may extend providing loop end tines having a transverse contour of generally streamline form as shown in Fig. 3. The top of the portion 101 may be provided with an axially extending channel or groove 104. A blade clamp plate (Fig. 6) 105 is pro- Vided with a pair of axially disposed tongues 106, for cooperative engagement in the groove 104, and with a centrally disposed threaded hole 107. A blade 2d is placed on the under face of the plate while the latter is upside down (Fig. 6) with the tongues 106 engaged in the usual blade slots. While the blade is held in such position by the fingers of the operator the plate and blade are inserted through an open end of the cage, with the tongues 106 disposed in the groove 104 (see Fig. 5) until the hole 107 is centered over a cooperating hole in the portion 101. The threaded shank of a screw 108 is then screwed into the hole 107 of plate 105 until the blade is firmly clamped in its cutting plane, which passes through the center of the edges of may be replaced by the same process. The head of screw 108 is made with a slot (not shown) to facilitate member; thus permitting a short or relatively flat head lying close to the contour profile of the cage. It is especially noted that the blade holder and wire loop tines are so disposed that, with the blade clamped in cutting position one edge may be snugly disposed against the interior of the bight of one series of loop tines, as at 110, while the other edge is spaced a substantial distance inwardly from the other series of loop tine bights such as 111; in order to provide for cutting short hair with one edge and long hair with the other edge.
The ribs or tines are spaced apart a sufiicient distance, about A; of an inch, which will permit the skin to be depressed by adjacent tines, causing the skin surface to be raised therebetween, into the shaving zone into which the edge of the blade is positioned. The height that the skin is raised is dependent somewhat on the pressure used, the spacing and the thickness of the between .015 to .030". The edge of the blade may actually touch the inner surface of the tines, or it may be spaced therefrom a distance of say 34 to which edge the skin surface will project when the tines are depressed on the skin.
In Figs. 7 to 10, I have shown variations of the embodiment of Figs. 1 to 6.
Referring to Fig. 7, the plate holder is provided with a lower member 120, having an tical with the plate 105 above described and a lower member corresponding to the portion 101 above described with reference to Fig. 3. It will thus be seen that the blade 2e is removably held in the blade holder in the manner previously described with reference to Fig. 3. The lower member 120 in this embodiment may be made from solid stock and is conveniently provided with a handle portion 126 which extends in axial alignment with the holder in the manner of the handle 100 above described with reference to Figs. 1 and 2. As in the previous embodiment (Figs. 1-5), the cage 32 may comprise a plurality of wire ribs such as 127 providing a series of wire loop tines having their bights such as 128 and 129 arranged and disposed as illustrated. The Wire ribs such as 127 are secured to the framework in a somewhat different manner; the ribs 127 on their lower side extending beneath the blade holder member 120 and being securely fastened thereto in fixed spaced relation such as by means of a plate 130. With this construction the ribs such as 127 may be made separately or may be formed from a continuous strip of wire in the general form of a helix which may be flattened to the desired con-. tour shown and the ribs such as 127, corresponding to respective helices, may be thereafter straightened into desired alignment. Where a continuous wire is used the Patented Oct. 21,1958.
the wire loop tines. The blade its operation by the use of a coin or other interfitti ng loop tines, which may be helices or rib portions thereof may be locked in slots, or otherwise secured to the plate 120 and the lower plate 130 may be omitted; in which case the plate 120 alone will be the cage spine. The shank of the clamp screw 125 passes freely through the clamp plate 1.30 and blade holder member 120 in between adjacent portions of the under side of the Wire ribs such'as 127.
In Fig. 8 I- have shown a structure identical with that shown in Fig. 7 except that the upper clamp plate designated 122' has its upper surface disposed in contact with the interior of the upper wire ribs such as 12.7. The remaining parts of this embodiment are designated in Fig, 8 with the same numerals as referred to in connection i h Pie 7 w t head e P m In Fig. 9 l have illustrated the two-position hair cutter with' ani opening between. two sets of ribs 12%. In this modification the ribs 127a incl n towards the cutting edges of the blade 2 from an offset portion 127 b, in turn connected by a flat spine section 1270. These offset portions form passageways between ribs for passing the hair therethrough. The, clamp screw 125a is threaded to a clamping plate 107a through the blade 2 the two spine sections 1270, and through the plate 105a which forms part of the handle. In this version the blade edge 2g may be positioned about from the intersection of the plane of the blade and the outside surface of the ends of the ribs. This has been found to give a satisfactory distance for trimming. the hair to shorter lengths. The edge 2h may be positioned from the intersection of the plane of the blade and the outside surface of the ends of the ribs, which has been found suitable for close shaving with ribs'spaced A" apart.-
In Fig. another modification is shown with a guard plate 104b having slotted curled up ends 1040, having about the same spacing and width as the ribs. The clamp screw 1 25b is threaded to the clamping plate 105b, which is' attached to the handle, through rib spine 127d, blade 2 and guard plate 1041). The curled up ends 1040 project beyond the blade edges 2k and 2m to provide an obstacle to accidental contact with the edge of the blade. In the case of edge 2m, a line passing through the outer skin contacting surface of the ribs and the edge of the blade may pass longitudinally through the slain contacting edge of the guard plate, as is shown in my co -pending case Serial No. 344,157, filed March 23, 1953, now Patent No. 2,746,144 granted May 22, 1956.
The blade position fixing means at all times holds the blade edges parallel with the outermost portion ofthe ribs, and readily permits detachment of the blade for replacement.
I have found that the angle 0, Fig. 10, defined as the angle between the plane of the blade and the outside face of the ribs 127e, which acts as a guide surface, may not be less than 10 nor more than 45 and preferably between 20 and 35. 1
The handle may be of any form. As illustrated in Fig. 1, it is suitable for cutting the hair with either the right or left hand.
The ribs and other component parts, except the blade, may be made of wire, stamped or cast metal, or molded plastic material such as nylon.
This is a continuation-in-part of my application Serial No. 106,398, filed July 23, 1949, now abandoned.
I have thus described my invention, but I desire it understood that it is not confined to the particular forms or uses shown and described, the same being merely illustrative, and that the invention may be carried out in other ways without departing from the spirit of my invention, and, therefore, 1 claim broadly the right to employ all equivalent instrumentalities coming within the scope of the appended claims, and by means of which, objects of my invention are attained and new results accomplished, as it is obvious that the particular embodiments herein shown and described are only some of the many that can be employed to attain these objects and accomplish these results.
