ATTACHMENT FOR SAFETY RAZORS Application filed December 12, 1930. Serial No. 561,968.

An object of the invention is to provide an attachment for safety razors which is normally mounted on a handle of the safety razor and which has resilient arms engagnlg a guard plate of the safety razor to hold the guard plate in normal position when it 1s moved slightly away from the razor blade and the clamping plate of the safety razor to permit of the use of the safety razor to insure a close shave.

Another object of the invention is to provide the attachment with diverging resilient arms which will engage the guard plate adjacent its ends to obtain a firm hold on the guard plate and in this way maintaln the guard plate in position.

Still another object of the invention is to provide the attachment with an opening in which the handle of the safety razor is d1sposed, the attachment 7 resting against a shoulder on the handle and being provided with means engaging and holding the guard plate in position.

A further object of the invention is to provide an attachment which serves to prevent water and lather from running down the handle of a safety razor from the plates and the razor blade held therebetween.

Additional objects of the invention will appear in the following specification in which the preferred form of the invention is described.

In the drawing similar reference characters refer to similar parts in all the views,

' of which Figure 1 is an end view of a safety razor provided with the attachment,

Figure 2 is a sectional view on the line 22 of Figure 1,

Fi ure 3 is a fragmentary sectional view on the line 33 of Figure 2, and

Figure 4 is a perspective view illustrating the attachment.

When desiring a close shave with a safety razor it has been customary with the old type of razor blades to unscrew the handle slightly, which serves to change the positions of the edges of the blade relatively to the guard and clamping plates, the resiliency of the blade serving to press the guard plate against the shoulder on the handle, by which means the parts are held in place and the further unscrewing of the handle is retarded. With many of the new types of razor blades this is impossible for there is so much metal cut away at the central portion of the razor blade that, in connection with other features of the new blade, the desired pressure is not exerted by the razor blade against the guard plate.

My invention overcomes this difliculty by providing a shield or member engaged by the handle for pressing arms against the plate for holding the plate in normal position. The outward pressure against the handle also serves to press the sides of the thread on the handle against the sides of the thread on a stud projecting from the clamping plate to retard the unscrewing of the handle. The shield or member also serves as a means to prevent lather from running down the handle of the safety razor.

By referring to the drawing it will b seen that the attachment 10 is used on a stand ard type of safety razor having a handle 11 with a threaded opening 12 in which meshes a threaded stud 13 on a clamping plate 14:, which serves to press the razor blade 15 against a guard plate 16. When a razor blade is used in this type of safety razor where considerable of the central portion of the razor blade is cut away, or where the razor blade for some other reason has not sufficient stren th to press against the guard plate 16 when the handle 11 is slightly unscrewed relatively to the threaded stud 13, the razor blade will not exert any considerable pressure against the guard plate 16, although the edges of the razor blade will be disposed, as will be understood, so that a close shave may be obtained. The failure of the razor blade to exert any pressure against the guard plate 16 will result in the guard plate 16 having some movement relatively to the razor blade 15, which will render the razor dangerous when used. Furthermore, when the handle 11 is slightly unscrewed relatively to the threaded stud 13, there will not be such frictional engagement as will prevent the further unscrewing of the handle when the razor is used, and which may also render the razor dangerous during the shaving process.

With the attachment 10 these dificulties and disadvantages are avoided inasmuch as the attachment 10 consists of a shield or member 17 with an opening 18 through which the upper end of the handle may be disposed to permit. of the shield or member 17 resting against the shoulder 18 on the handle. The shield or member 17 hasbroad diverging, resilient arms 19, the terminal of each arm having a bearing seat 20, so that the arms 19 may be disposed in the direction of the guard plate 16 and may rest against the said guard plate with the bearings 21 on the guard plate 16 resting'in the seats 20 ofthe shield or member 17.

It will be understood that the attachment may be quickly applied to the safety razor and that inasmuch as the arms19 engage the guard plate 16 at its rib or hearing 9.1,at points spaced from the handle 11 at the guard plate, a firm grip will be obtained on the guard plate because of the resiliency of the arms. The guard plate 16 will, therefore, beheld andwill be prevented from movement under all normal conditions. lVhen the handle 11 is slightly unscrewed so that the edges of the razor blade will be disposed to obtain a close shave, the plate 16 will'be freed from close proximity to the clamping plate 14 and the pressure of the guard plate 16 against the razor blade 15 will be greatly reduced. Nevertheless, although the shoulder 18 on'the handle 11 will move away from the clamping plate 1d wh n the guard plate 16 is freed from close proximit to the clamping plate 14, the desired adjustmentwill be obtained by means of the arms 19 against the guard plate 16- under all normal conditions. The resilient arms 19 will press against the guard plate 16 to hold the guard plate .16 firmly in position. I

. What is claimed is:

1. In'combinationwith a safety razor having. a guard plate and a clamping plate for embracinga razor blade and a handle with a shoulder, amember mounted on the handle at the shoulder and having resilient, diverging, non-compressible arms for detachably engaging the guard plate for holding the guard plate in normal position when the clamping plate has been moved therefrom to permit of a close shave. 1

2. In combination with a safety razor have ing a razor-securing means with sides and ends and a handle with ashould'er spaced from the razor-securing means, the handle haying a threaded engagement with the razor-soeuringmeans, a lather shield mounted on the handle at e shoulder and having noncompressible resn ent arms disposed at opposite sides or" thehandle and detachably engaging the enc s of the razor-secur ng means for pressing against the razor-securing means from the shoulder for steadying the latter, the arms being free from the razorsecuring means between the ends of the latter.

3. In combination with a safety razor having a plate with sides and ends for engaging a razor blade and a handle adjustable relatively to the plate, the plate being provided with bearings adjacent its ends, a member mounted on the handle, means to limit the movement of the member relatively to the handle, the member having arms with seats for detachably receiving the bearings on the plate and for pressing from the said means for holding the plate in normal position, the arms being free from the plate between its ends.

l. I11 combination with a safety razor having a plate with sides and ends for engaging a razor blade and provided with a handle adjustable relatively to the plate, the plate having bearings adjacent its ends, a member mounted on the handle, means for limiting the movement of the -member. relatively to the handle, the member having resilient, diverging, metal arms with seats for detachably receiving the hearings on the plate for pressing from the said means for holding the plate in normal position.

' 5. In combination with a safety razor hav ing a handle with a shoulder and a guard with raised portions, a resilient shield mounted on the handle at its shoulder and provided with a ms having corrugations normally cooperating with the said raised portions on the guard to prevent relative angular displacement of the shield and the guard.

6. A resilient shield having a central portion with an opening in which a razor blade handle is normally disposed, the ends of the resilient shield curving in one direction with their terminals bent in substantially the same plane and substantially parallel with the said central portion of the resilient shield, there being a corrugation in each terminal for cooperating with raised portions on a razor guard.
