Application filed Hovember, 1920. Serial no. eaneeo.

To all whom it may concern Be 1t known that 1, Uncut L. Honnms, a

citizen of the United States, and resident of Little Valley, Cattaraugus County New York, have invented ce State of rtain new and useful Improvements in Safety Razors, of which the following is a specification.

My; invention relates to safety-razors and more particularly to that class thereof in which the blade is of substantially the form found in the usual ordinary razor and in which an attachment including a guard is detachably combined with said blade with the guard arranged to lie contiguous to the cutting edge thereof. Such tachments, generally speaking,

with the blade by sliding thereof and are held in place by means of an elastic clamp of guards or atare comblned them over the back by friction or suitable construction. With such arrangements, the possibility of relative movement of the attach-- ment lengthwise of the blade during use reduces the element of safety equipped. Furthermore, an the indicated character, being drawn from in razors thus attachment of by being capable of the blade with the guard in its operative position, also tends to dull and otherwise injure tion contemplates the the blade. lily invenprovision of a simple and novel construction in which the above disadvantages are overcome lengthwise movement with the guard thereof in its and in which of the attachment,

operative position, is positively prevented and separation of said attachment from the razor blade is possible only after said guard has been adjusted to an inoperative position out of contact with the blade.

A further o jfi f Y invention is to provide a structure in which the guard is capable of being side of the. blade or whereby said applied to one the other, with means guard 18 firmly fixed agalnst lily invention will be fully described hereinafter and the features of novelty will be pointed out in theappended claims.

In the accompanying draw lustrate an embodiment of without defining its limits,

ings, which ilmy invention Figure 1 is a side view of a razor provided with my improvements; Fig. 2 is an enlarged the line 2-2 of Fig. 1; Figs.

cross-section on 8, a and 5 are detail views of the safety attachment separated from the razor and F larged section thereof on th Fig. 4.

ig. 6 is an ene line 6--6 of j ecti ons clips 15 forming integral parts of said carrier I and arranged to engage the sides of the blade as shown in Fig 3. A plate 16, which, in the operative position of the parts, lies in surface engagement and in registry with the carrier 14, is pivotally connected therewith at 17 so as to be movable in a plane transverse to the plane of the blade 10. The plate 16, at its opposite ends, is provided with lugs 18 for the accommodation of trunnion's 19 whereby the swinging guard 20 is hinged upon said plate 16, theguard being of any customary type and having the usual fingers or the like 21 adapted to extend beyond the cutting edge of the way.

With this arrangement, the guard 20 is reversible by being first swung to an inoperative position on' its'trunnions 19 after which the plate 16 is rotated about the pivot 17 to bring the guard to the opposite side of blade 10. In order to firmly fix the plate 16 bladein the well known in its adjusted positions in registry with the carrier 14;, the latter may be provided-with projections 22 arranged to fit into recesses 23 on the plate 16, the inherent resiliency of said plate being relied uponto snap the recesses and projections and to maintain them the guard against the blade on either of its To disconnect the recesses 23 and pro- 22 or to release the flange 24 from the projections 23 it is simply necessary to exert a force sufficient to overcome the resilient resistance of the parts.

For the purpose of securely fixing the attachment on the blade against relative movement in the direction of its length, when the guard 20 is in its operative position, said guard is provided at its opposite sides.

end edges with lugs 25 arranged to extend over and engage the inner end edge or both end edges of the razor blade 10 as shown in Fig. 2. With thisarrangement, it is impossible to slidably slip or withdraw the attachment from the razor blade when the guard is in engagement therewith; to permit any movement of the attachment in the direction of its removal, it is first necessary to swing the guard 20 to an inoperative position out of contact with the blade 10. Movement of the attachment relatively to the blade in a direction toward the handle 13 may be prevented either by the one lug 25 in co-operation with the outer end edge of the blade 10,

or by means of an car 26 depending from the carrier 14 over said end edge of the blade 10.

The attachment is thus firmly fixed upon the blade against unintentional relative movement, thereby increasing the element of safety to a maximum degree; at the same time, by making it impossible to withdraw the attachment from the blade with the guard in an operative position, thecpossibility of cate cutting edge of said blade 10 is obviated. The device is very simple in construction and provides aneflicient and easily adjustable attachment whereby an ordinary razor may be readily converted into a safety razor.

Various changes in the specific form shown and described may be made within the scope of the claims Without departing from the spirit of my invention.

I claim:

1. A safety attachment for razors comprising a carrier arranged to be slidably slipped upon the back of the razor blade in a lengthwise direction, a plate pivotally connected with said carrier to swing about an axis transverse to the cutting edge of the blade, a guard pivotally connected with said plate and movable about an axis parallel with said cutting edge in directions toward and away from the same to operative positions upon opposite sides of said razorblade in'contact therewith and to inoperative positions out of contact with'said blade and lugs located upon opposite end edges of said guardand partaking of the pivotal movements thereof, one of said lugs, in one or the other of the operative positions of said guard being arranged'to project over the dulling or otherwise injuring the deli inner end edge of the razor blade, to main tain the attachment against a sliding withdrawal from said blade when said guard is in either of its operative positions in contact with said blade.

2. A safety attachment for razors com-' arranged to be slidably slipped upon the back of the razor blade in a lengthwise direction, a plate pivotally connected with said carrier to swing about an axis transverse to the cutting edge of the blade, co-operating projectiens and re cesscs upon said'carrier and plate whereby the latter is fixed against unintentional pivotal movement about said transverse axis relatively to said carrier, a guard pivotally connected with said plate and movable about an axis parallel with said cutting edge in directions toward and away from the same to operative positions upon opposite sides of said razor blade in contact therewith and to inoperative positions out, of contact with said blade and end edges of said guard and partaking of the pivotal movements thereof, one of said lugs, in one Or theother of the operative po, sitions of said guard being arranged to project over the inner end edge of the razor blade, to maintain the attachment against a sliding withdrawal'fromsaid blade when said guard is in either of its operative positions in contact with said blade.

3, A safety razor comprising a handle, a blade connected therewith, a carrier slidably mounted upon the back of said blade, a guard located upon said carrier and pivotally movable about an axis parallel with the cutting edge of the blade toward the same to an operative position in contact with said blade adjacent to said cutting edge and away from the latter to an inoperative posiarisin a carrier tion out of contact with said blade and a lugcarried by said guard and partaking of the pivotal movements thereof, said lug, in the operative position of said guard, projecting over the inner end edge of said razor blade to maintain said carrier and guard against withdrawal from said blade when the guard is in said operative position in contact with said blade.

In testimony whereof I have hereunto set my hand.
