GILLETTE SAFETY RAZOR COMPANY, OF BOSTON, MASSACHUSETTS, A CORPORA- TION OF DELAWARE SAFETY RAZOR Application led March 29, 1929. SerialNo. 350,860.

My improvements relate to the class of safety razors in which a blade is clamped-for shaving between two members, commonly alleda guard member and a backing mem- An object of my invention is to provide a razor., lof the class referred to, with resiliently'operating means adapted to position the two members and the blade in shaving relau lo tion one to another, and to aiiord a convenient guiding means for the blade when the latter is placed upon the guard member for assembling the parts.

My invention comprises novel details of construction which will be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings in which,

Fig. 1 is a partly sectional side view of a razor embodying my invention;

Fig. 2 is a cross section of Fig. 1; Fig. 3 is a plan view of the razor Fig. 4 is an exploded view of parts of the razor, partly in section; Y

' Fig. 5 is an enlarged detail view, partly in section, illustrating the parts assembled for `inal positioning, and Fig. 6 is a similar View illustrating the parts kin shaving relation.

Similar numerals 'indicate corresponding parts in the several views. The numerals 1 and 2 indicate bladeclamping members, the member 1 being shown provided with guards 3. The member 1 is a guard member and the member 2 is a backing member adapted to clamp blade 4 between them. The guard member 1 is shown provided with spaced holes 5 adapted to register with corresponding openings 6 in the blade and with correspondingly positioned registering recesses orfopenings 7 in the underside of the backing member. At 8 are positioning pins 0r projections slidably carried by the handle 9, said pins being adapted to enter the holes 5 in the guard member, the openings 6 `in the blade and the recesses or openings 7 in the backing member, (Figs. 5 and 6). The'pins 8 are shown l carried -at one end of a sleevef' 14g-that is mounted to slide along handle 9, and said sleeve is resiliently pressed outwardly along the handle`toward the guard member by a spring 11. Said spring is shown in the form of a coil encircling the adjacent part of the handle and located within the sleeve 10, the spring bearing at its outer end against the sleeve and at lts inner end against a stop or shoulder 12 on the handle. The outer end of the handle is shown provided with a head or shoulder 13 against which the sleeve is pressed by the spring when the parts are separated-to retain the sleeve on the handle, which head or shoulder bears against the guard member when the parts are assembled for shaving, Fig. 6. For convenience in manufacture the handle is made in two parts 9a and 9b, the part 9a having a recess 9c receiving the part 9b, whereby/the sleeve 10 and the spring may be assembled on the part 9b, after which the said parts 9a and 9b may 2). The backing member 2 is shown provided with a threaded projetcion 15 operative in a threaded recess 16 in the handle for securing the parts in assembled position for shaving.

When the parts are to be assembled the sleeve 10 will bear against the head 13 of the handle, with the pins 8 projecting outwardly, and guard member 1 will beplaced against said head with the pins 8 projecting through the holes in said member, as in Fig. 5. The blade then may be placed upon the guard member with the pins 8 projecting through the openings 6 in the blade, andthe acking member may be placed upon the blade. The

handle will be rotated with respect to the" threaded projection 15 to draw the-backing member against the blade, and during such operation the pins 8 will enter'the recesses 7 o the/backing and will bear against the bottoms of said recesses, whereby the pins 8 and the sleeve 10 will be pushed back, permitting the backing member to bend theblade as required, for assembling the parts for shaving, as in Fig. 6.

The spring 11 "keeps the pins 8 resiliently pressed against the backing member, providing a tension between the threaded projecbe secured together by a pin or rivet 14, (Fig.

I tion 15 and the threaded recess 16 and said pins serve to register the blade in relation to the guard member. The blade cannot become released from the guard member while the tension of the pins against the backing member is maintained. The pins 8 alsoserve to .retain the backing member in proper position respecting the blade edge. The resiliently operating pins 8 serve in aligning the forth without departing from the scope of ber having the appended claims.

Having. now described my inventionwhat I claim is :efl. A safety razor comprising a guard member, a backing member, a handle, separable from one another, means to clamp the members, the handle and a blade together, and means slidable on the handle toward and from the backing member and separate from the handle, the members and the blade and cooperative with the members and the blade for aligning and retaining the said members and positioning a blade therebetween in shaving relation.

2. A safety razor as set forth in claim 1 provided with resilient means forretaining said aligning means in operative relation to the said members and the blade.

3. A safety razor as set forth in claim 1 provided with a spring carried by the handle and operative with the aligning means for retaining the latter in operative relation to the said members and the blade.

razor comprising a guard memoles, a backing member having recesses to register with said holes, a handle, pins slidably carried by the handle to enter said holes to bear against the backing and recesses and to enter openings in a blade between lthe guard member and the backing member to align said members and position the blade therebetween in shaving position, and means to clamp said members, the handle and the blade together.

5. A safety razor comprising a guard member having holes, a backing Lmember having recesses to register with said holes, a handle, pins movably carried by the handle to enter 4. A safety said holes and recesses and to enterlopenings in a blade between the guard member and the backing member to align said Ymembers and position the blade therebetween infshaving position, means to clamp said members, the vhandle and the blade together, and a spring to resilientlyretain said pins in operative relation to the said members andthe blade.

6..A safety razor as-setA forth in claim 5 in which" the spring is carried by the handle and operative with said pins for retaining the latter in operative relation to the said members and the blade.

j 7. A safety razor comprising a guard member having holes, a backing member having corresponding recesses, a handle, means operative between the backing member and the handle for clamping said members upon a blade provided with openings, a sleeve slidable on the handle, pins carried by said sleeve and operative in said holes, openings and recesses .for aligning the blade with respect to the guard member, and means to retain said pins in operative relation to th'e said members and the blade.

8. A safety razor as set forth in claim 7 in which the means to retain the pins includes a spring carried by the handle and operative with the sleeve.

9. A safety razor comprising a guard member having holes, a backin member having bers and the blade. 10. A safety razor as set forth in claim 9- in which the handle comprises two members, the spring and the sleeve being mounted upon one of said members and the other member having a stop for the sleeve.
