OOHBINATION HAIR 'rnmm AND SAFETY RAZOR.

Application filed December 88, 1919. serial No. 847,340.

To all whom z't may concern: I

Be it known that 1, JOHN H. Gowns, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented a new and useful Improvement in Combination Hair Trimmers and Safety Razors, of which the following is a specification.

This invention relates particularly to a device adapted to he used either as a haircutter or as a safety-razor; and the primary object is to provide an improved device of this character which is thoroughly durable, which can be taken apart and assembled with the greatest facility, and which is of improved operation.

T the invention is illustrated, in its preferred embodiment, in the accompanying drawing, in which-- Fig. i represents a plan view of the improved device, looking towardthe outer face of the shoe employed, oblique position of the (mirth-plate being indicated by dotted lines; Fig. 2, an elevational view of the device, adjusted for use as a safety-raaorg Fig. 3, an under or innerside view oi the shoe; Fig. 4, a plan view of the blade; Fig. 5, an outer or lower side view of the conch-plate; Fig. 6, broken sectional view taken as indicated at line 6 of Fig. 1, showing the device equipped with a handle applied at one end, enabling the device to he employed in much the manner of an olddashioned razor; and Z, an enlarged sectional View showing the device ready for use as a hair-trimmer.

in the illustration given, A represents a shoe which is to make contact with the face or head; iii, a blade which bears against the under or inner side of the shoe; L, a comb-plate which is adapted to clamp the blade to the shoe; D, a clampingecrew adapted to secure the comb-plate and the interposed blade to the shoe; and E, an

' elongated handle which can he used interchangealoly at the ends of the shoe, or in the manner illustrated in 2.

The shoe A is provided with an inclined wall 1 which is elongated longitudinally so as to he oi approximately the same length as the blade. This wall terminates at its tront edge in a redn too 2, and the rear portion of the wall is provided with an integral heel 3. The heel and toe portions of the shoe are separated by a longitudinal space 4. The lower or inner surfaces of the toe and heel portions of the shoe are preferably curved, or beveled slightly so as to provide longitudinal bearmgs for theblade at the points 5 and 6. The shoe may comprise a casting or drop-forging. The heelportion 3 is in the shape of a longitudinal ledge, or projection, which is provided with a-central threaded socket 3 and with interlock lugs 3 which flank said socket. At its front side, the heel-portion is cut away, or recessed, at points 3, these recesses opening into the recess 4 under the instep of the shoe. These recesses lighten the shoe. At the rear corner of the heel, there is rovided a longitudinal recess 7 which is ad apted to accoodate a rear flange with which the comb is provided, when the comb is in the forwardly shifted position. At the end of the heel-portion of the shoe are provided threaded sockets 8 adapted to receive a screw of the same dimensions as the central socket 3 The shoe is provided with a longitudinal recess 9 which is partially overhung by the rear portion of the wall 1. The heel is provided at its rear side with a projection which afi ords a curved shoulder 10. The recess 9 has a concave wall, the curve of which is extended and merged with the convex surface 10. Thus, the rear ortion of the shoe afiords a finger-grip, which enables the device to be grasped between the fingers and thumb, the thumb engaging the head of the clamping-screw l).

The blade B is provided with a central perforation 11 and with slots, or perforations, 12, flanking the central perforation and adapted to engage the interlock lugs of the shoe.

The comb-plate C is provided at its front edge with teeth 13 and preferably has its rear edge equipped with a longitudinal flange 14, which is adapted to be housed in the recess 7 of the shoe when the combplate is projected forwardly to the full extent. The comb-plate is provided with a central slot 15 which extends forwardly from a point near the rear edge of the combplate, The metal bordering this slotis preferably struck downwardly or away from the shoe, to provide a head, or strengthen ing rib, 15 At points flanking the central slot, the comb-plate is provided. with slots 16, which engage the interlock lugs 3. lhe slots 16 are somewhat wider than the length of the interlock lugs 3, thus permitting the comb-plate to be swung to an oblique position, as indicated by dotted lines in Fig. 1. The purpose is to graduate the length 0 the hair in the trimming operation. 7

The clamping-screw D has a reduced threaded perforation which screws into the socket 3, and also has an enlarged head 17, at the base of which is a shoulder 17 adapt- .ed to bear against the bead 15 bordering the center slot 15 of the comb-plate. Thus the clamping-screw is adapted to clamp the comb-plate and the interposed blade to the shoe. The enlarged head 17 of the clamping-screw is provided with a curve 17 of comparatively large radius, which enables the thumb to grasp the screw in opposition to the fingers which engage the finger-grip of the shoe. It is preferred to provide the outer end of the clamping-screw with a threaded socket 17 of the same dimensions and pitch as the sockets 3 and 8.

The handle E is in the form of a shaft 18, which is equi ped at its inner end with a reduced threa ed portion, or screw, 18, which is adapted to screw into any one of the sockets mentioned. The-handle is also provided with a clamping shoulder 18".

The manner of using the improved device may be described briefly. With the parts assembled as shown in Fig. 7, the device may be employed for cutting or trimming the hair; and, if desired, the comb-plate may be adjusted to an oblique position, so that the ends of the teeth will coincide with an inclined line forming an angle with the cutting edge of the blade. Thus, the teeth will project successively further and further from the edge of the blade. This enables the hair tobe trimmed closer at the edges than could be accomplished were the teeth all to project the same distance from the ed e of the blade.

y retracting the comb-plate, or moving it rearwardly with relation to the shoe and blade, the comb-plate may be set so as to enable the device to be employed as a safetyrazor. When the proper adjustment is made, the device can be employed either in the condition shown in Fig. 7 or the handle E may be applied and the device employed in the condition shown in Fig. 2. However, if desired, the handle E may beapplied to the shoe at either end thereof by turning the screw-portion 18 of the handle into one of the soc ets'8. In this condition, the device may be employed very much as an ordinary razor is em loyed. While the handle E is shown-in clamping-screw D, it is possible to remove ig. 2 as screwed into thethe screw D and use the handle E as the clam in -screw for securing the comb-plate and la e to the shoe.

The improved device may be manufactured at moderate cost, may be assembled and disassembled with facility, and may be converted to suit the user, who may employ either the short handle D, or the longer handle E, or both, and the longer handle E may be disposed at right-ancgles to the plane of the com late, or exten mg from either end of the s oe, as desired.

The foregoing detailed description has been given for clearness of understandin only, and no unnecessary limitation shoul be understood therefrom, but the appended claims should be construed as broadly as permissible, in view of the prior art.

What I regard as new and desire to secure by Letters Patent, is:

1. A device of the character set forth, comprising a shoehaving its inner side adapted to bear against a blade, said shoe having an inclined outer surface meeting the plane of the b ade and having its rear portion equipped with a finger-grip, a blade bearing against the inner side of said shoe, a combplate between which and said shoe said blade is interposed, and a clamping screw securing said comb-plate and blade to the rear portion of said shoe, said clamping screw being ada ted to serve as a thumbpiece, whereby t e device may be grasped between the thumb and fingers.

2. A device of the character set forth, comprising a shoe having one side adapted to engage a blade and provided with a longitudinal recess and having an inclined surface at the other side, a comb-plate provided with a central slot and two widened slots flanking the same, a blade interposed between the shoe and comb-plate, and a clamp ing screw extending through said slot and engaging a threaded central socket in the heel-portion of said shoe.

3. A device of the character. set forth, comprising a shoe having an inclined wall terminating at its front edge in a toe, the

rear portion of said wall having formed integrally therewith a ledge affording a heel,
