SAFETY-RAZOR.

Specification of Letters Patent.

Patented Apr. 25, i911.

Application'flled August 15, 1908. Serial No. 448,738.

To all whom it may concern:

I Be it known that I, ROBERT T'ArLoR, a subject of the King of Great Britaln and Ireland, and residing at 1 Pembury road, Clapton, London, NE., En land, have invented certain new and usefu Improvements in and Relating to Safety-Razors, of which the'following is a specification.

a with This invention relates to safety razors with reciprocating blades and has for its object to obtain an improved razor .of this The lnventlon consists 1n the improved safety razor hereinafter described.

Referring 'to the accompanying draw ings:-Figures 1 and 2 represent a safety razor according to one form of the invention. Figs. 3 and 4 represent respectively the plan and side elevation of a safety .razor according to a further form of my invention in which the blade is mounted in a secondary frame which slides on the roller spindle. Fig. '5 represents a detail of the form of my invention in which pinion wheels and the like are used for transmitting the motion of the grip roller to the frame carrying the razor blade.

In carrying out the invention according to the form illustrated in Figs. 3 and 4 I support the safety razor blade a, in a holder composed of a fixed member 11, and a spring hinged member 12, attached rigidly to ,a

secondary frame p which is mounted so as to slide laterally to and fro along the thin and sufliciently long spindle g of a surface gripping roller 9 in such a way as to permit rotation of the spindled roller within a primary frame 1- or by like means. Then by truncating the ends of the said roller in parallel planes oblique to the roller axis as shown at s or in like manner and in such a way as to engage accurately and easily with rounded points it at the extremities of arms forming part of the secondary frame p both the said secondary frame 39 and obviously the blade at with it are moved to and fro so as to give the required zigzag sawing effect,

as the roller 9 rotates when drawn over the face in shaving. The truncation of the ends of the roller 1 in themanner above referred to,'permits the to and fro action to occur any given point of the blade edge will, in action, describe not so much a wavy course as a course that is abruptly zigzag. Small roller or other antifriction devices as indi-' rompt alternate reversals, and thusv I cated at 16 in Fi s. 1 and 2 to assist easy working may desired.

It ,should be stated that the surface grip roller (1 mentioned in connection-with the above-described device constitutes the guard a so be supplied where for the blade and is arranged in suitable close proximity to'the blade a for this purpose, the actual distance between the. guard and blade being set as desired. In the forms illustrated the roller is shown as not substantially longer than the blade and of equal external diameter throughout, but these features are by way of example and not necessary to the invention.

Proper'blade skin angle is maintained by guide projections, u, or other suitable parts of the primary'frame r constructed loosely to engage with the blade holder 11, 12: or secondary frame 39 and supporting it above the roller level. t

In Fig. 5 is shown adetail of a modified construction in which the obliqueends of the roller 9 of Fig. 3 are replaced'by a cam collar 00 on an enlargement w formed on a shaft '0 geared to the grip roller 9. This connection is, shown through teeth formed on the cam collar :12 and the grooves of the grip roller g. The cam collar a: transmits a reciprocating motion to the blade aby a v forked extension Z connected to or forming part of the frame p.

In carrying the invention into effect in the form illustrated in Figs. 1 and 2, the razor blade, a is. carried in suitable clips I) attached to a plate 0 of a frame formed of the plate or and depending side pieces 15. A

spring piece (Z attached to this plate 0* presses the blade ainto the clips Z) and keeps the same in position. Depending from the plate 0 is a plate 14 having a projection 0, adapted to enter a groove 7 in the rotatably mounted gripping roller g, so that'when this roller revolves the plate 0 and with itthe blade (1 receive a lateral motion, the frame being loosely mounted on .shafts i and h which pass through the side members 15 and through the plate l i respectively. The main frame j carrying these shafts has a handle is attached thereto of any suitable form. As the gripping roller is moved over the face the blade a receives the required zigzag motion from the cam groove 7 by the engagement therewith of pro ection e rigidly connected to the plate 0 to which this blade a is attached.

If the shaft 2' ismade removable the blade carrying structure can be turned about It forthe purpose of cleaning.

the present invention.

I claim 1. In a safety razor, the combination of a frame, a razorblade removably mounted on said frame-,a roller disposed 1n close proximity to the cutting edge of the blade to act as a blade vguard, a cam surface on said roller, and means connected wlth the frame a andcontacting with said surface, whereby the movement of the roller over the face during shaving causes the blade to reciprocate.

2; In a safety razor, the combination of a frame, a carrier movably, mounted upon said frame, a razor blade removably supported on said carrier, a roller disposed in close proximity to thecutting edge of the blade to act as a blade guard, a cam surface on said roller and a projection on said frame coacting with the cam surface whereby the movement of the roller over the face during shaving causes the'blade to reciprocate.

3. In a safety razor, a frame, a carrier movably mounted upon said frame, a blade -supported 'by said carrier, a projection on saidframe, a roller situated in close proximity to the blade edge and constituting a blade guard, and a cam surface on said roller adapted to coact with the-projection movablylmounted upon said frame, a blade onsaid frame whereb the movement of the roller over the face uring shaving causes the blade to reciprocate.

t. In a safety razor, a holder, a frame adjustably earned by said holder, a carrier remova y secured upon said carrier, ides for iding said carrier in the directlon of the ength of said blade,'a roller disposed in close proximity to saidblade constitutin a blade guard and a cam surface on sai roller adapted to coact with a projection on causes the blade to have a motion compounded of the motion in the direction of its length and the motion in the direction of the line of travel of the holder.

5. In a safety razor, a holder, a frame adjustably carried by said holder, a 'guard disposed in close proximity to the razor blade, said guard being in the form of a roller with a cam surface adapted to convert a motion of the holder into a reciprocating motion of the'razor blade, and a movable member carried by said holder operated by said cam surface.

6. A safety razor comprising a frame, a razor blade detachably mounted on said frame, a roller situated in close proximity to said razor blade to act as a face guard and also to transmit mot-ion to the razor blade, a cam surface on said roller, a blade carrier comprising a spring member and hinged clip, a frame supporting said blade carrier and means connected with said frame and contacting with the cam surface of the roller.

7. A safety razor comprising a blade having a lon itudinally continuous cutting edge, a roller isposed in close proximity to said blade and constituting a b ade guard, a cam groove in said roller, a blade carrier, and a projection on said carrier adapted to engage said roove.

8. A sa ety razor including in combination a blade having a longitudinally .continuous cutting edge, a cam roller disposed in close proximity to said blade and constituting a blade guard, a pivotally mounted blade carrier and a projection on said carrier adapted to engage said cam roller.

9. In a'safety razor, the combination of 3 a frame, a razor blade removably mounted on said frame, a roller disposed in close proximity tothecutting edge of the blade to form a bladeguard, and means connecting the frame and roller to effect reciprocation of the said frame on the rotation of the said roller to cause the blade to reciprocate.

' In testimony whereof I have herepnto set my hand in presence of two subscribing witnesses.
