SAFETY-RAZOR.

Specification of Letters Patent.

Patented Apr. 9, 1912.

Application filed November 4, 1910. Serial No. 590,611.

- To all whom it may concern:

New York city, borough -of Manhattan, in

the county of New York and State of New York, have invented certain new and useful Improvements in Safety-Razors, of which the following is a specification.

My invention relates to improvements in safety razors, and has for its object to permit the blade edge to project more or less over the guard within limlts as desired for producing a close or coarse shave, and generally to improve the razor.

My invention comprises novel details of improvement and combinations of parts 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 1 is a face view of a safety razor embodying my improvements, the handle and part of the guard being partly broken away; Fig. 2 is an edge view thereof; Fig. 3 is a central section substantially on the

line

3, 3, in Fig. 1; Fig. 4 is an underside view of the. razor partly in section on the line 4, 4, in Fig.1; Fig. 5 is a detail of the resilient blade engaging lugs or stops; Fig. 6 is a detail sectional view substantlally on the plane of the line 6, 6, in Fig. 3; Fig, 7 is a detail of the springplate 1 3, and Flg.

8 is a section on the

line

8, 8, of Fig. 3, look- 1 suitable blade holder 3, the 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. The blade 4 is adapted to coact with a suitable guard 5 which may be of any suitable or well known construction, said guard being shown provided with comb-teeth and with lugs or hooks 5* adapted to engage the blade to retain it'in shaving position with respect to the guard. Said lugs or hooks 5 are shown located so that the portion of the blade adjacent-to its cutting edge may slide between the adjacent part of the guard and said lugs or hooks, for which purpose said lugs or hooks areshown located at the ends of the guard to receive the ends of the blade.

So far as my present improvements with respect to theguard are concerned, the blade supporting parts and the guard, as well as the means for supporting and operating the guard, may be of any well known or desired construction wherein the guard is movable with respect to the blade support. In the example illustrated in the accompanying drawings I have shown a blade support and guard, and means for operating the guard, substantially the same as that set forth in 'my application for patent on safety razor.

filed May 3, 1910, Serial No. 559,174, wherein, and in the accompanyingdrawings, the means for operating the guard are as fol lows: The guard 5 is provided with an extension 5" project-ing in the direction sub- 'stantially transversely beneath support 1.

Extension 5 is shown suitably shaped so as to pass through an opening 6 in the downwardly extending projection 7, (serving as a handle) that is. suitably attached to support or frame 1. Theinner portion of extension 5, within the projection or handle 7, is shown provided with a downwardly disposed branch 5 that is pivotally carried by the projection or handle 7.- To properly and yet detachably pivotally supportbranch 5 the same is shown provided with. one or more projections 5, serving as pivots, that are movably supported in plate or piece 8 fitted within projection or handle 7, and said plate being provided with corresponding openings 8 receiving projections 5 whereby the guard is pivotally supported for adjustment with respect to the blade.

Plate 8 may be retained within projection or handle 7 by any suitable means, such as by being pushed against shoulder or stop 7 and retained frictionally; One or more shoulders or stops 7 may be provided, whichmay be done by suitably pressing the metal of projection or handle '7 inwardly at 14: where the upper portion 7 of projection or handle 7 is shown squared above the tubular portion 7 At 9 is a worm or screw carried by support 1, and shown suitably journaled upon projection or handle 7 and meshing with threadsfi suitably formed on or applied to the appropriate part of extension 5". Threads 5 are shown formed on a suitably curved part of extension 5 that is substan- I 7 Sin va substantially concave manner, as at 9?,

soasto remain in mesh with threads 5 as the latter move. For convenience in applymg and supporting worm 9 the same may be journaledin a" plate having a depending 1?) lug or wall. 1O provided with an opening or bearing for the adjacent pivotal end of worm 9, and the upper end of projection or handle 7 is provided with a bearing receiving the adjacent pivotal part 9* of said worm,.'whereby said worm is journaled to rotate. in mesh with the complemental teeth 5"; Plate 10 may be clamped between the base or support 1 and projection or handle Q7..by screws 11- passing through lugs 7- of said handle and meshing in threads in frame 1. a

By rotating-the worm in one direction the guard will be moved outwardly to release the blade, and by adjusting the blade to the guard and rotating the worm in the required direction, the guard willbe drawn toward the-blade edge, so that the latter will be ad jetted and retained in shaving position with respectto the guard, and by rotating the worm more or less the blade edge will be oausedflto project more or less forwardly with respect Ito the guard.

Since the arts above described are illustrated and described in my aforesaid application Serial No. 559,174, except the construction of the handle with its shoulders or stops/Z and. 14, the same are not herein specifically claimed,.but are set forth herein to illustrate suitable means for carrying my present invention into effect. I In addition to the'foregoing I have shown means to maintain the teeth 5 of extension 5 in relativelyclose mesh with the worm 9.

Tothis end I provide a resilient or spring plate 13 adapted to rest upon plate or piece f8."and provided with the recesses or openings. 13. to receive projections 5 of branch '5,.said plate bearing under the lower portion 5 of branch 5. The spring 13, in bowupwardly, permitting teeth 5 to work freely in the worm',:keeping said parts in relatively close relation and taking up wear that may occur between said teeth and worm.

In accordance withmy present invention I provide resilient or spring-acting stops or lugs. upon. the guard to engage, the blade edge, whereby to retainthe blade projected more or less substantially over the guard i: and to effect adjustment for a close or coarse shave, as desired. To this end I have shown a spring-like piece 12 extending along the guard and provided with stops or lugs 12, I which project upwardly in front of the blade fii edge near its earners. the piece 12 being at? form, this normally presses the branch 5 tached ataboutits central portion to the guard by any suitable means, such as by solder, a rivet or the like.

I have shown piece 12 as provided with outwardly projecting arms 12 carrying the stops or lugs 12*, said arms being shown provided with slots 12 receiving pins or projections 14: carried by the guard frame.

taining the arms 12 in proper position, permit freedom of movementof said arms relatively to the guard frame, and limit the action of the spring stops 12% The arrangement of the parts is such that the stops or lugs 12 are normally maintained inwardly relatively to the guard, and when the guard is moved or drawn toward the blade, stops 12 will contact the blade edge and piece 12 will bend more or less, thus serving to retain the blade in desired adjusted position upon the guard, providing adjustment for a coarse or close shave, according tohow much the guard is adjusted with respect to the blade, the lugs or hooks 5 retaining the blade upon the guard. The worm 9 and teeth 5 serve as a positive force to overcome the normal tension of the spring-stops 12. The arrangement is such that when the guard is moved or pushed outwardly the blade edge will be free from all of the lugs and stops, and when the guard'is moved inwardly or toward the blade edge the latter will first slide under the lugs 5*, and then contact with the stops 12 and then the guard will slide under the blade more or less according to adjustment of the guard.

My invention is not limited to the details of construction set forth, as the same may be varied, within the scope of the appended claims, without departing from the spirit of my invention. v Having now described my invention what I claim is v 1.
