5 Claims. (on. 30-40)- This invention relates to an improved safety razor and also a loading device therefor, the two members being adapted to fit together for temporary co-operation for the transfer of .a blade from the magazine to the razor. The

type of article is shown in my patent issued 4 August 14, 1934, Number 1,969,945.

The improvment resides in a razor adaptable for spreading of the blade channel in two directions for the easy transfer of a blade and also in a magazine which effectively spreads the shaving head of the razor in the two directions.

The invention also comprises certain details of construction which will be more fully described hereinafter and finally embodied inthe claims. g I

The invention is illustrated in the accompanying drawing in which Figure 1 is a face view of my improved razor and the magazine or loading device therefor. Figure 2 is a section on line 22 in Figure l with the razor head in blade clamping position. Figure 3 is a view similar to Figure 2 showing the parts of the shaving head separated by the magazine. Figure 4 is a top view showing the razor and one end of the magazine when the parts are'assembled. Figure 5 is a perspective of the attaching end of the magazine. Figure 6 is a longitudinal central section through the magazine.

The razor is of the type that is provided with a recess for the reception of a tongue of the magazine and which tongue not only is held by the razor for maintaining the razor head and magazine in alignment but also acts to spread the razor head for readily receiving a blade. For this reason the razor head is made of metal having considerable resiliency. yet stiff enough to hold the blade firmly and to prevent any chattering of the razor when used in shaving. The form shown comprises a front member having a blade platform Ill anda plate It and a rear member comprising a top plate 12 somewhat hook-shaped and a plate 53.

The plate 83 bent outwardly at It to form a longitudinal passage l5, one wall of which is provided by the rear face of the plate ll. These two parts, the front part and the rear part are held together near the bottom of the plates H and I3. I find that an economical way oi forming the razor and providing a comfortable handle is to make the razor out of one piece of spring metal integral with the front and rear members and bent at the bottom into a loop l6 which forms a handle. The spring tendency of the metal is to force the blade platform l and the top plate I! together. I provide a latch, preferably by forming a spring hook I! on the front plate, this hook extending upwardly which hook is adapted to enter a slot IS in the back platel3 and hold on the top edge IQ of the slot l8. When the shaving headis opened all that is necessary is to push down firmly on the part l0 or the front bend of the -loop 16. This disengages the hook ll from the plate I! and it can be swung forward and the two partsof razor are free at their ends, as the natural spring tendency of the metal is to separate the parts l0 and I2 slightly. When the parts are to be reassembled the front bend of theloop 15 I6 is pressed down and back to catch the hook ll into the slot l8 and the spring action of the metal forces the hook ll into place and brings the parts l0 and i2 together.

This spring pressure acts to hold a blade by pressure of the top plate I2 on the top side of the blade and of the blade platform III on the bottom side of the blade. The blade is held at its back edge by the rear wall of the top plate l2 and is thus held'in proper shaving position relative to the guard 2i fashioned 2 at the front edge of the blade platform. The front edge of the blade may be positioned by the stops 22 at the corners of the front edge of the blade platform. 1

The magazine is designed to feed blades end- 3 wise into the shaving head, to be held in align-- ment for proper feeding of the blade by cooperating means on the shaving head and the magazine, and said means acts to separate the two spring members of the shaving head by both lateral and vertical movement.

The body portion 23 of the magazine, is in the form of a box which receives the stack of blades M, from which stack the blades are propelled, one by one, through a slit 25 in the end of the box. The magazine is provided with a finger 26 which fits into the'passage it in the. razor head and bears on the walls of the outwardly bent portion It to press the top plate l2 upwardly and also rearwardly.

In the case of a rectangular passage,-as shown,

two forces act to raise the top plate |2 from the top face of the blade 20 and to move the heel of the top plate 'rearwardly from the blade and out of-the path of the blade that is to be injected into the razor.

The magazine may receive blades in a stack and the preferred way is to place the blades in a clip 3| which clip has an opening in the bottom. A spring 32 projects up through the opening and keeps the stack pressed upwardly. The spring is fastened to the bottom 33 of the box 23. The bottom 33 may be hinged as at 34 and held in place by spring cars 35 which have depressions 36 that snap into recesses in the side walls of the box and hold the bottom, in place. The lip 3! acts to hold the clip 3| in place and also as a means for swinging the bottom to open and close it.

The 'blades are ejected, one by one, by a plunger 38 which extends along the top of the clip against the under side of the top of the box. The rear end of the plunger is fastened to a finger piece 39 by a lip 40. The finger piece is preferably U-shaped and rests on the top of the box and has roughened side flanges 4| extending part way down the sides of the box. The lip 40 which connects the ejector slide 38. and the finger and in feeding a blade can be a single continuous one toward the razor, and in the same manner, the withdrawal of the slide by' its handle 33 is in the same direction as the withdrawal of the magazine from the razor and when continued separates the magazine from the razor. Thus a single motion may be used to insert the magazine and inject a blade, and a second single motion retires the ejector slide and then withdraws the magazine from the razor. This latter operation leaves the handle of the injector slide at its rearmost position ready for insertion of the magazine into the razor and subsequent injection of a blade.

The handle loop I6 is curved forwardly relative to the shaving head and the plates and I3. This disposition of the parts gives to the two members of the shaving head a tendency to press toward each other and to hold the hook I! in place on the edge l9 It also assists in seating the hook l1 when itis passed into the slot it, from the front.

The tapered parts 21 and 29 of the finger 26 are located preferably near the magazine which disposition spreads the end of the shaving head that is-nearest the magazine to a greater extent than the farther end. This is clearly shown in Figure 4. The advantage of this is to retire the wall or heel 30 and raise the top plate |2 a greater distance at the end of the razor where the blade enters. The parts are moved but little at the far end and the stop 22 at a in Figure 4 acts as a brake which prevents a blade fromriding beyond its proper position if too forcibly in- Jected into the razor and the friction between the blade, the blade platform and the top plate assist at this point in sldwing up the incoming blade. At the same time the wall 30 and stop 22 on plates for detachably holding of the finger to raisethe top plate |2 except at its farthest end where it might rise slightly. This also causes the heel 3|! to ride to the rear to make room for the incoming blade. The handle 39 of the injector slide 38 is now pushed in by a continuation of the motion that inserted the finger 26. The blade is pushed endwise by the plunger and passes into the shaving head with its shaving edge, as at 43, out of contact with the-stop 22 at b and out of contact with the nearer end of the heel or wall 30. At the completion of the injecting stroke the blade is halted as the injector is stopped by the engagement of the lip 40 with the end of the slot 42. The injector slide is now withdrawn by the handle 4| and the engagement of the lip 46 with the other end of the slot 42 carries the magazine along and the finger 26 is drawn from the passage 36. The top plate |2 now being released, the spring in the metal forces the wall 30 to push the blade forwardly to shaving position relative to the guard 2| and causes the top plate to bear down on the top face of the blade.

In case a blade is already in the razor, the new blade pushes the old blade out, and as the pushed blade is to be discarded it does no harm to have its cutting edge press lightly along the stop 22 at a.

The razor, as illustrated, may be made of one piece of metal which is of the proper resiliency and weight to maintain its form under shaving pressure but which is adapted for easy separation by the finger of the magazine. The hook n is lochteilnat a point where it is held in. place by the sp g action of the loop- I6 and any pressure on the loop |6 due to squeezing by the hand is localized in the loop, the hook |'l preventing any appreciable eifect on the parts of the shaving head.

Various changes may be made in the proportion and shape of the parts without departing from the scope of my invention as set forth in the claims.

I claim:

1. The combination of a safety razor including a blade platform and top plate, spring means for resiliently holding the top plate in place, said means including a bent portion forming a passage, with a magazine of blades including a blade projecting mechanism, and a finger in the magazine adapted to enter the passage, said finger being tapered in two directions to engage the walls of the passage whereby the top plate is both raised and moved rearwardly.

2. A safety razor consisting of a sheet of metal bent into an elongated loop to form a handle, plates extending upwardly from the loop, a blade platform extending forwardly from one plate, a top plate extending'forwardly from the other plate and bent over the blade platform to hold a blade on the platform and means the ends of the looped part together.

3. A safety razor consisting of a sheet of metal t a top plate extending forwardly from the other plate and bent over the blade platform to hold a blade on the platform, the rear plate being slotted, and an upwardly extending hook to catch over the top edge of the slot, the loop being extended forwardly toward the bottom to cause a spring action with a tendency to move the blade platform and the top plate toward each other.

4. The combination of a razor having spring members forming a shaving head to hold a blade, the head having a passage therethrough between the members, with a magazine, a finger on the magazine to enter the passage for holding the magazine and razor head in alignment and for spreading the spring members, the finger extending longitudinally from one end of the magazine, an injector slide reciprocablefrom one end of the magazine, a handle at the rear of the slide and limited in its movement to the dimensions of the magazine. whereby the injecting movement of the slide is in continuation of and in the same direction as the movement of inserting the magazine.
