RAZOR.

Specification of Letters Patent.

Patented Sept. 6, 1910.

To all whom it may concern:

Be it known that I, ALONZO A. VARNER, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Razors, of which the following is a specification.

My invention relates to improvements in safet-y razors, and the objects of my improvements are convenience and efficiency in use, and particularly as applied to the guard.

In the accompanying drawing Figure 1 is a side elevation of my safety razor, showing the handle in part broken away. Fig. 2 is a side elevation of the clamp member. Fig. 3 is a side elevation of the guard plate. Fig. 4 is a side elevation of the slide plate. Fig. 5 is a sectional view on the line x m of Fig. 1 on an enlarged scale. Fig. G is an end view of the guard plate. Fig. 7 is an end view of the slide plate.

My razor comprises a blade A of sheet metal which is removably held in a blade holder B by means of lugs 10 on the back edge of the blade, tting and adapted to be received longitudinally in a tubular back 11 in the said blade holder, and held against longitudinal displacement by means of a latch C adapted to engage with the inner end of the blade, constituting essentially a fiat blade with a cylindrical back, and provided with a handle D.

My razor is provided with a guard member or guard and means of support therefor E, comprising a guard 12 and means for adjustably holding the same in position on the blade A as will be herewith described. The said guard 12 has the usual comb formation and extends along the front edge of an essentially rectangular plate F constituting a guard plate. Backwardly from the said guard 12 along the inner face and extending from the same to the back edge 13 the said guard plate F is provided with a plane bearing surface 14 which is of appreciable width and adapted to bear against the side of the said blade A. The plane of the said bearing surface 14 is set inwardly from the said guard 12 so that when the same is in contact with the blade the guard is set away from the edge 15 of the blade by a space 16 affording clearance between the blade and guard. The outer surface 17 of the said guard plate F is generally a plane surface, and is provided with a longitudinal way in the form of a groove 18 adjacent the said back edge 13 and with an outwardly proj ecting pin 19 located preferably equidistant from the ends and at a point opposite to the said bearing surface 14. The said guide pin 19 is a lit for a cross-wise slot 25 in the front clamping wing 24 of a clamp member G yet to be described and the said groove 18 is a lit for and adapted to serve as a guide for the inner ends of a pair of guide pins 21 which pass through and are Xedly secured to a slide plate H, also to be described. As a support for my guard plate F I provide the said clamp member G and slide plate H. The said clamp member G comprises a tubular back 22 fitting over the said cylindrical back 11 of the blade A and two forwardly projecting clamping wings comprising a rear clamping wing 23 adapted to bear and exert a clamping pressure against the rear side of the blade remote from the said bearing surface 14 and a front clamping member 24 extending correspondingly along the said outer surface 17 of the guard plate F and adapted to exert a clamping pressure on the front side of the blade indirectly through the said sliding plate H which is interposed between the same and the said surface 17 of the guard plate F. The said front clamping member 24 is provided at the middle of its length with the said cross-wise slot 25 eX- tending backward from the front edge 26 which as described is a fit for the said guide pin 19 and adapted as a guide for said guide pin and in coperation with the same serves to maintain the longitudinal relation of the guard plate and clamping member constant and unvaried throughout the range of adjustment provided for the guard 12. On each side of the said guide slot 25 the said front clamping wing 24 is provided with two diagonal parallel bearing slots 27 adapted to receive and serve as guides for the eX- treme outer ends of the said guide pins 21 on the slide plate H. The said slide plate H comprises generally a flat plate of a thickness sullcient to lit between the said front clamping wing 24 and the guard plate F, projecting below the said front edge 26 of the same at the middle at which point the same is turned outwardly to provide an operating handle 28 and provided on each side with holes 29 adapted to iixedly receive the body of the said guide pins 21, the ends of which pins project on each side in a manner and for the purpose described By means of the said inner ends of the pins 21 in engagement with the said groove 18 the said slide plate H may be slid back and forth longitudinally relatively to the said guard plate and without change in the lateral or cross-wise relation of the said slide plate and guard plate. Because of the engageiiient of the outer ends of said pins 21 with the said diagonal parallel slots 27 in said clamp wing 24C such longitudinal movement on the part of the slide plate is accompanied by a lateral or cross-wise movement of the slide plate and guard plate combined as a unit relatively to the said clamping wing 24. To provide clearance for the said slide plate H for the guide pin 19 the same is cut away as at 30, at the middle, along the edge remote from the handle 28. Accordingly, my guard plate F is clamped to the blade A by means of the clamp member Gr with a predetermined clearance between the guard and blade and the amount of projection of the said guard 12 relatively to the edge 15 of the blade may be varied and without change in the relative longitudinal relation of the said guard and blade. Furthermore my guard is readily removable and is reversible and adapted to be placed in position on either side of the blade for either left hand or right hand use.

In operation the guard plate is clamped to the blade by the clamp member, the sliding plate being interposed between one of the clamping wings and the said plate, the guide pins in the side plate being in engagement with the way 1S by their inner ends and with the diagonal slots 27 by their outer ends, and the guide pin 19 is in engagement with the crosswise slot 25, the guard 12 being adjacent the edge of the blade. In case it is desired to shift the guard relatively to the edge of the blade the operating handle 28 of the slide plate is moved longitudinally and the desired change is effected through the cooperation of the guide pins and slots which are engaged in the manner described.

I claim as my invention 1. A safety razor having a blade, a guard plate provided with a guard and a clamp member having means for clamping said guard plate on said blade, and comprising means of adjustment of the said guard plate relatively to the said blade consisting of a longitudinal way on said guard plate, diagonal slots on said clamp member, guide pins having ends, and means whereby the said guide pins may be removed back and forth and the inner ends of the said guide pins being engaged with the said way and the outer ends engaged with the said diagonal slots.
