SAFETY-RAZOR.

Patented Apr. 9, 1912.

Application led May 3, 1910. Serial No. 559,174.

To all whom t may concern Be itl known that I, HENRY J. GAISMAN, a citizen of the United States, and resident of New York cit-y, borough of Manhattan, in the county of New York and State of New York, have invented certain newv and useful Improvements in Safety-Razors, of which the following is a specification.

The object of my invention is to provide improved means for supporting and adjusting the guard in a safety razor, and for re'- `taining the same in adjusted position with respect to the blade edge, and whereby the blade edge may be caused to project more or less over the guard, within limits, as desired, and also whereby the distance between the vguard and blade edge maybe adjusted and maintained as desired for producing a close or coarse shave.

My invention comprises novel details of improvement that will be more fully hereinafter set forth and then pointed out in the claims.

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

Figure'l is a plan view ofa safety razor embodying my invention; Fig. 2 is a sect-ion on the line 2, 2, in Fig. 1; Fig. 3 is a similar View showing the parts in other positions;'

Fig. 4 is a rear viewy of the razor; Fig. 5 is a section substantially on the line 5, 5, in Fig. 2; Fig. 6 vis a detail broken view of the guard supporting arm; Fig. 7 is a detail view of the worm or screw for controlling the guard; Fig. 8 is a section on the line 8, 8, in Fig. 5, illustrated at right angles to Fig. 5, part 5C being omitted, and Fig. 9 is a detail view of the worm supporting plate hereinafter referred to.

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

The numeral 1 indicates a suitable frame shown provided with uprights 1il spaced apart and supporting a rod or shaft 2, said rod or shaft carrying a suitable blade holder 3, t-he parts `described being so spaced that, if desired, a strop may be passed through the frame beneath the blade for sharpening the edge of the blade. Blade 4 is adapted to coact with a suitable guard or seat 5 which `may be of any suitable or well known construction, said guard being shown provided with comb-teeth and with lugs or hooks 5El adapted to engage the blade to re-` tain it in shaving position with respect to the guard. Said lugs or hooks 5a are shown located so that the portion of the blade adjacent to its cutting edges may slide between the adjacent part of the guard and its lugs or hooks. Guard 5 is provided with an arm or extension 5b suitably shaped so as to pass through an opening 6 in handle 7 that is suitably attached to frame 1. The inner portion of arm or extension 5b, within the handle, is shown provided with a downwardly disposed branch 5F that is pivotally supported by the handle. To properly and yet detachably pivotally sup port branch 5 the same is shown provided with one or more projections 5d,-serving as pivots that are movably supported in a plate or piece 8 fitted within handle 7, and provided with corresponding openings 8a receiving projections 5d, whereby the guard is pivotally supported to swing toward and from frame 1 and with respect to the blade. Plate 8 may be retained within handle 7 by any suitable means, such as by being pushed against shoulder or stop 7a and retained frictionally.

At 9 is a worm or screw suitably journaled,fas upon handle 7, and meshing with threads 5e suitably formed on or applied to the appropriate part of arm or extension 51. The threads 5e are formed on a suitably curved part of arm or extension 5b that is substantially on a circle described around the pivotal point of branch 5C, and worm 9 is properly shaped to mesh with threads 5e during movement of arm 5b, as by shaping worm. 9 in a substantially concave manner, as indicated at 9a (Fig. 7), so as to remain properly in mesh with threads 5e as the latter move. For convenience in applying and supporting worm 9 I have shown alplate 10 (Fig. 9) having a depending lug o-r wall 10a provided with an opening or bearing 10 for the adjacent pivotal end of worm 9, and the upperl end of handle 7 is provided with a bearing or slot 7b receiving the adjacent pivotal part. 9b of worm 9, whereby said worm is journaled to rotate in mesh with teeth 5e. Plate 10 is shown clamped between the base of frame 1 and handle 7 by screws 11 passing through lugs 7c of said handle and meshing in threads in frame 1. rThe arrangement described is such that t-he worm 9 may be readily applied to and removed from the razor and will be properly retained in position of coaction with threads 5e of arm 5b. Means may be provided for retaining worm 9 in set position. Fdr this purpose I have shown' the handle 9c of said worin as provided with a suitable projection 9d adapted to engage recesses or apertures 9e formed in or on handle 7 whereby when the handle is set in any desired 'position the worm will be kept from rotating. y y,

In accordance with my improvements, by rotating the worin inv one direction the guard will be moved outwardly to release the blade, -as indicated in Fig. 3, whereupon the blade is free to be stroppcd, cleaned, or removed and replaced, and by adjusting the blade upon the guard and then rotating the worm in the required direction the guard will be drawn toward the blade edge so that the latter will be adjusted and retained in shaving position with respect to the guard, as indica-ted in'Fig. 2. By rotating the worm more or less the blade edge will be caused to project more or less forwardly with respect to the guard, and the hooks or lugs 5El will retain the blade and guardv in adjusted position. As the guard is pivotally supported at the parts 5d, 8a it will have movement toward and from the blade edge in a substantially circular direction which will facilitate or cause the blade edge to bear more or less closely against the guard to regulate for a coarse or close shave.

My invention is not limited to the details of construction shown and described, as the same may be varied, within the scope ot' the appended claims, without departing from the spirit thereof.

In this application I do not broadly claim a guard having an extension pivotally supported by or within'the handle and operated by a worm, since that rsubject matter embraced in my application for safety razors, filed September 4, 1909, Serial No. 516,165.

Having now described my invention what I claim is 1. A safety razor comprising a blade support, a guard or blade seat, means for pivotally supporting the latter, said guard having an arm provided with a curved portion described around the axis of the arm and provided with teeth extending in the direction of movement of the arm, a worm meshing with said teeth, and means for otally supporting said Worm.

2. A safety razor comprising a blade support, a guard or blade seat, means for pivotally supporting the latter, said guard having an arm provided with a curved portion described around' the axis of the arm and provided with teeth extending in the direction of movement of the arm, a worm meshing with said teeth and means for pivotally supporting said worm, said worin being formed concave between its ends.

3. LA safety razor comprising a blade support, a handle, a guard provided with an arm having a branch located within7 said handle, a plate within the handle provided with an opening, said branch having a projection movably retained insaid opening, said arm having teeth, a worm meshing with said teeth, and means `for pivotally supportin the worm.

4. A sa ety razor comprising a blade support, a guard provided with an arm, means for pivotally supporting the arm, a worm meshing with complemental means on the arm, a handle supporting said arm and worm, a plate having a lug providedwith an opening receiving said worin, and means for retaining said plate in position.

5. A safety razor comprising a blade sup port, a guard provided with an arm, means for pivotally supporting the arm, a worin meshing with complemental means on the arm, a handle supporting said arm and pivworm, a plate having a lug provided with an opening receiving said` worm, and means for retaining said plate in position, said handle having al bearing for the worm at lthe side opposite said lug.

6. A safety razor comprising a blade support, a guard, means for pivotally supporting the "guard, a worm, means for pivotally supporting the worm, complemental means on the arm coacting with the worin, said worm having a handle provided with an extension, `and the frame having a handle provided with rentrant parts receiving said projection to retain the arm in set position.

Signed at New York city, in the county of New York, and State of New York, this 29th day ofApril, A. D. 1910.
