ATTACHMENT FOB. SAFETY RAZORS.

Application tiled June 9, 1922. Serial No. 567,119.

To all. whom t4 may concern:

Be it known that I, MILTON THAYER NEW- MAN, a citizen of the United States, residing at Miami, inthe county of Dade and State of Florida, have invented certain new and useful Improvements in Attachments for Safety Razors, of which the following is a specification. f.

Thls invention relates to razors, and the primary object of the invention is to provide an attachment for safety razors which is so constructed as to effectively holdv the blade against movement during all adjustment of the razor, and to prevent the clogging up of the guard plate.

In use of safety razors of the character disclosed in U. S. Letters Patent 775,135 granted November 15, 1904, on the invention of King C. Gillette, hereinafter termed original Gillette type, difliculty is experienced in shaving when theI razor is ad justed for giving a close shave, due to the fact that the blade is loosened in the holder.

which permits movement or chattering of the blade, causing the cutting of the skin of the user. In an improved razor disclosed in Patent #1,328,024, issued-J an. 13, 1920, on the invention of Edward R. Wharton, the guard late of the original Gillette type is modifie t0 prevent clogging of the uard plate and to permit adjustment of the lade to be had'without the loosening thereof in the holder. While this safety razor of thev new type accomplishes its purpose, the improvement cannot be readily incorporated in the razor of the original Gillette type,

thus necessitating the buying of a complete new razor.

It is therefore another prime object of this invention to provide an insert for connection with safety razors of the original Gillette type for effectively spacing the l blade from the guard plate to. prevent vclogging of the plate and to permit a wide range of ,adjustment ofthe blade to be had relative to the ard plate without the loosening of the b ade in the holder.

'A still further object of the invention is to provide an improved attachment for safety razors of the above character, which will' be durable and eicient in use, one that will be simple and easy to manufacture,and one which can be readily associated with thesafet `razor in an expeditious manner.

With these and otherobjects in view, the

invention consists in the novel construction,-

arrangement and formation of parts, as will be hereinafter more specifically described, clalmed and illustrated in the accompanying drawings, forming a, part of this specification, in which drawings: v

Figure l is an edge elevation of a safety razor, showing the improved attachment or insert 4incorporated therewith prior to the adjustment of the blade.

Fi re 2 is a similar view showing one adjuste position of the blade. y

Figure 3 is a similar'view showing another adjustment of the blade.

Figure 4 is a section taken on the line 4-4 of Figure l, showing the improved attachment orinsert in plan.v

Figure 5 is an edge elevation of a safety razor, showing the modified type of attachment or insert incorporated therewith.

Figure 6 is a detail perspective view of the modified form of attachment or insert.

Figure 7 is an edge elevation of a safety razor, showing a still further modified type of insert or attachment incorporated therewith.

Figure 8 is a section taken on the line 8-8 of Figure 7, showing a further modified form of the insert or attachment in plan.

While three forms of the improved atl tachment or'insert havebeen illustrated, it is to be understood that other forms may be made without departing from the spirit or scope of the invention.

The razor A is, as stated, of the ori inal Gillette type and includes the elongate arcuate sha ed cap plate 1Q, which normally overlies t e elongated arcuate sha ed guard plate 11 with the concavity of t e former confronting the convexity of the latter. The cap p ate 10 supports the inwardly extending pins 1 2 for the shaving blade 13, and these pins are adapted; to extend through the bladev in the ordinary manner and throu h the guard plate 11. l'Adjustment is h between the guardplate 11 and cap plate-10 inthe ordinary manner, and the cap plate 10 cansupport the inwardly extending centrally disposed stud 14 on which can be threaded the handle 15. Thus,'by turnin the handle, the blade 13 is adapted to be exed and held rigidl in place between the cap late and tie guard plate 11. The guar plate has its .lateral edges provided, of course, with. the usual guard j teeth 16.

In all of the forms of the improved attachment or insert, the same is adapted to be placed between the ard plate 1'1 and the lade 13, as clearly s own 1n Figures 1 to 3 inclusive, 5 and 7. x

The improved insert or attachment B is preferably formed of flexible spring matcrial, such as steel and consists of an elongated plate, having its ends curved, so as to conform to the general configuration of a Gillette safety razor blade. llhis plate is adapted to extend at least the full length of the guard plate 11, and is of such a width that its lateral edges will lie inwardly of the guard teeth 16, as clearly shown in Figure 4 of the drawin s and linwardly of the longitudinal edges 0% the cap plate 10, as shown in Figures 1 and 2. This plate 17 is provided with a pair f longitudinally extendi ing corrugations 1 on opposite sides of its longitudinal center with their convexities engaging the guard plate, and the longitudina or lateral edges of the plate are preferably struck downwardly at an incline as indicated by the reference character" 19. At the longitudinal center of the plate 17, suitable openings 20 and 21 are provided respectively for the ide pins l2 for the blade 13 and the adjusting stud 14.

In use of the attachment, the blade 13 is placed on the pins in the ordinary manner, after which the attachment B is placed on said pins and the guard plate l1 is moved into engagement with the attachment. The handle 15 can now be adjusted in the usual way. The attachment will first assume a position as shown in Figurell of the drawings, holding the blade 13 into intimate engaglement ywith the longitudinal edges boun in the concavity of the cap plate 10. As t e handle 15 is adjusted, the attachment and blade will be flexed, as shown in Figure 2 of the drawings, so as to` arcuate into the cavity of the cap plate, brmgmg 5the cutting edges of the blade closer to the ard teeth 16. The handle canbe adjuste until the plate 17-is' flexed to such a position that the same assumes an arcuate configuration as shown in Figure 3 of the drawings. This, of course, brings the. cutting ed es of the blade 13 relatively close to the tee A16 lbut at the same time spaces the cutting edges of the blade a suiiicient distance away from the guard teeth to prevent the clogging up thereof by the beard of the user. t

In the form C, the attachment consists of a rectangular shaped plate 25, which has `a.

length substantially equal to or more than the guard plate 11 and a width less than the width of the cap plate and guardI plate so that the longitudinal edges of the plate 25 will lie well inwardl o'f the guard teeth 16 formed on the guar plate 11. This plate 25 isl also formed of resilient material and is preferably formed of a plurality of relativel thin laminations 26. At the longitudina center of the plate 25 is dsposed a pair of openings 27 fort-the blade guider ins 12 and a central opening 28 for the a justing stud 14. This attachment is placed on the razor in the same manner as the form A and adjustment can be had in the same manner. If it is found, however, tliatthe blade 13 cannot be adjusted close enough to the guard teeth 16, certain laminations can be torn oi' of the plate 25, thus reducing the same in thickness.

In Figures 7 and 8 of the drawings is illustrated the forni D of the attachment, which consists ot' the longitudinally extending spaced parallel'bars 30, connected by transverse strips 31, which may be provided with openings 32 for the reception of the pins 12. The bars 30 may be of circular shape 1n cross section, if so desired, and it can besecn that these bars form fulcrum shoulders on which the blade can be flexed. This attachment also spaces the edges of the blades a suiicient ldistance from the teeth 16 to prevent thc clogging u thereof -as heretobefore dcscribed. Adjustment of the blade 13 relative to the teeth 16 can bc had by the turnin of the handle 15.

rom the foregoing description, it can be seen that an improved attachment has been provided for razors of the original Gillette type which will effectively permit a Wide range of ad'ustment of the blade `relative to the guar plate Without the blade losing its rigidity or chattering within the holder, and which will effectively prevent the razor from clog ing up, thus eliminating the necessity of telling the razor apart to clean the same during a' shave.

Changes in details may be made without departing from the spirit or scope of this invention; but, p

I claim:

l1. The combinatior with a safety razor including a cap plate and a guard plate, the

cap plate having 4a concave face confronting the guard plate, means for adjusting the plates relative to one another, and a. flex-A ible blade' engaging said cap plate; of a.

- a flexible insert relatively narrower than the cap plate, disposed intermediate the guard plate and blade, and acting up n said blade' to arcuate the latter into the/concavity ofthe cap plate and into intermediate contact with the longitudinal edges of the cap plate bounding said concavity.

4, The combination with a safety razor i including elongated cap and guard plates,

the plates having concave and convex faces, respectively, confronting one another,

means for adjusting the plates relative to one another, and a flexible blade engaging said cap plate; of a flexible insert relatively narrower than the cap plate, disposed intermediate the guard plate and blade, and acting upon said lblade`to arcuate the latter into the concavity of tlie cap plate and into intimate Contact y withA ,the longitudinal edges of the cap ;plate bounding said concavity.

5. The combination vwith a safety razor Vincluding elongated cap and guard plates,

the plates having concave and convex faces, respectively,v confronting one another, means foradjustmg the plates relative to one another, and an elongated' flexible blade relatively wider than said cap plate. but; relatively narrower than said guard plate disposed in engagement with said cap plate and provided with longitudinal cutting edges outwardly of said cap plate; and an elongated {iexible plate, relatively narrower than said cap plate, disposed between said blade and guard' plate, and provided with longitudinally extending corrugations spaced equidistant from the longitudlnal center of the iexible plate, the convex faces of which engage the guard plate, whereby upon movement of the cap and guard plates toward each other, the flexible blade will be primarily Vflexed into the concavity of the cap plate by engagement with the longitudinal portions of the flexible plate with the flexible blade adjacent the longitudinal edges of the Cap plate, and upon further movement of the cap and guard plates, the central longitudinal portion of the flexible plate will engage the central longitudinal portion of the blade and aid in arcuat-ing the blade into the concavity of the cap plate.

6. The combination with a safety razor including elongated cap and guard plates, the plates having concave and convex faces, respectively, confronting one another, means for adjusting the plates relative to one another, and an elongated flexible blade relatively wider than said cap plate but rela.- tively narrower than said guard plate, disedges outwardly of said cap plate; of an insert initially engaging the blade' at its face opposite to said cap plate and slightly inwardly of the longitudinal edges of the cap late at spaced apart lines to arcuate the b ade into the concavity of the cap plate and into firm engagement with the longitudinal edges oft e cap plate bounding said concavity, when the cap and guard plates are moved toward each other.
