position desired for use and whichalso serve to prevent the blade from sliding'ofi or being withdrawn from the holder when the clamp is removed. i

The structure for accomplishing the foregoingand other advantageous ends is illustrated in the accompanying drawings, forminga part of this specification, and in which Figure I is a front elevation, partly broken away, of astructure embodying my inven tion; I b Figure 2 is a transverse section on the line 22 of Fig. 1;

Fi ure 3 is a view similar to Fig. 1, the

holding clamp being removed and the parts being shown on a somewhat enlarged "scale; Figure is aview similar toFig. 1, .the blade being removed and a slightly modified form of guard platefbeing shown; 1 Figure 5 is a: plan View of a blade'adapted for use with the modified form shown in Fig.4;and

Figure .6. 1s a further modified arrange ment similar toFig. 3, the guard plate extending slightly beyond the rear edge of the 55 blade and having lugs to cooperatewith the rear edge of the blade which is straight.

Referring to the drawings in detail by the 7 reference characters thereon, the blade holder improved razor comprises a guard of my plate 10 to which a handle 11 is rigidly secured, and a substantially U-shaped spring clamping plate 12 which is adapted to hold a blade on the guard plate. The upper surface of the guard plate 10 is preferably flat and along one edge thereof, which will be termed the front edge, this plate is provided with guard teeth 13. At each end the guard plate 10 is provided with lugs 14 preferably formed by striking up the metal of the plate. The rear edge of each of these lugs 14 is prefera- 1926. Serial No.,113,258. v

bly straight for a purpose which willjlater appear. V p

In on'eform-of my invention, illustrated in Fig. 3, the rear edge of the plate 10 is provided with two lugs 15 whichare spaced apart and also preferably formed by strik ing up the metal 'of the plate. The lugs 14: and 15 it will be miderstoodproject upward ly above the'flat upper surface of the guard platelO, the height ofthe lugs 15 preferably being-substantially equal to, and not exceed ing the thickness of theblade.

The blade 16, which is adapted for use with the form illustrated in Figs. 1,2 and 3, is provided at each end with ears 17, the front edges of which are straight and which are adapted to cooperate, with the rear straight edges of the lugsll. On its rear edge the blade 16 issprovidedwith spaced notches 18 which are so arranged as to receive the lugs 15 when the blade is placed onthe guard plate. The lugs 14 and 15 onthe guard plate and the ears 1? and the notches 18 ofthe blade are so related that when the blade is in position the cars 17 will. rest against the lugs 14, and the lugs 15 will rest against the bottoms of the notches 18;

In the form illustrated in Figs and 5, the guard. plate 10 is provided at its ends with ears 14 as in the other form, but in this arrangement the rear side of the guardpla te is provided with a single upstandinglug 20 in place. of the two lugs 15in the first men; tioned form. Theblade16 for use with the formshown in Fig. 4 is also providedjwith ears '17 at its ends, but its rearedge is' provided with a single notch or recess 21 which] is adapted to cooperate with the lug 20.

In the form illustrated in Fi 6, the guard plate 10 is made slightly wider than the blade and two lugs 22 are struck up from the rear edge ofthe plate In this form the rear edge of the blade is made straight or Without notches, such straight edge being adapt ed to lie against the lugs 22, the blade also being provided with end cars 17 which are adapted to lie against the lugs 14.- on the. guard plate. It will be understood that the" lugs 22, like the lugs 15 and 20,project above the uppersurface of the-plate 10 a distance substantially equal to the thickness of the blade 16. g V

It will be understood that in each form of my invention the clamping plate 12 has an upper portion which is adapted to overlie a blade placed on the guard plate 10, this plate at its rear being provided wit-h an upwardly and downwardly curved portion 12 which terminates in spring arms 12 adapted to lie beneath the guard plate 10; The clamping plate is removable by merely sliding the same rearwardly off of the guard plate. V

- Referring to the form shown in Fig. 3, it will be seen that when a blade is placed on the guard plate 10, the lugs 14 and 15 cooperate with the ears 17 and notches 18 of the blade and serve to very accurately position the cutting edge of the blade with reference to the guard teeth and when the clamping plate 12 is applied the bladelG will be very securely held inposition, it be- 7 ing impossible for the same to move forward toward the guard teeth or rearwardly there from, with theresult that the cutting edge of the blade'is maintained in the position desired. In the form: shown in Figs. 4 and 5, the parts operate in a similar manner, the

lugs 14 and 20 cooperating respectively with the ears 17 and the notch 21 to maintain the blade in position. In the form shown in Fig. 6, the lugs let and 22 on the guard plate cooperate respectively with the ears 17 and the rear edge of the blade to accurately position and hold the blade. I 7 o In addition to the advantages of my improved structure already indicated, it possesses a further and very important advantage. In the form of razor shown in my prior patent above mentioned, it has been found thatfwhen the clamping plate is with-e drawn or slipped'ofl. rearwardly from the guard plate, it frequently happens that the blade is also withdrawn from the holder with the result that the blade may fall to "the floor and be injured or broken or sometimes the user is cut in trying tocatch the blade as it, falls. With my improved arrangement, the rear lugs 15, 22 or 20 will serve to prevent the blade from sliding off-the guard plate l0'when the clamp 12 is withdrawn and t-he'difliculty above mentionedis therefore obviatedas the blade remains on theguard plate when the clampingplate is removed. Also the lugs at. the rear of the guard plate being of a height substantially Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:

1. They combination in a safety razor, of a guard plate having guard teeth along one edge thereof, and having a flat upper surface, said plate adjacent each end having a lug extending above the upper surface of the plate, and also having one or more lugs at its rear edge the latter extending above the upper surface of the plate a distance substantially equal to the thickness of the blade, a blade mounted on said plate, said blade having an ear at each end formed with an edge adaptcdto engage said end lugs on the guard plate and said blade also having a rearvedge adapted to engage said rear lugs on the guard plate and a removable spring clamping plate having a flat portion engagingf'said blade andhaving a curved'portion extending around the rear of said guard piatea'nd engaging the lower surface-there o z 2. The combination in a safety razor, of a guard plate having guard teeth along one edge thereof, and having an upper bladereceivingsurface, said plate adjacent each end having alug exten'dingabove the upper surface of the plate, and also having a plurality of lugs at its rear edge, the last named lugs extending above the upper surface-of the plate a distance not exceeding the thickness of the blade, a blade mounted on said plate, said blade having an ear at each end formed with an'edge adapted to engage signature.

equal to or not exceeding the thickness of V the blade, do not interfere with the free rearward movement of the clamping plate in withdrawing the same from the guard plate.

Changes'may, of course, be made in the details of the foregoing structure without departing from the spirit of the invention as'covered by the appended claims. a
