SAFETY-RAZOR.

Specification of Letters Patent.

Patented Aug. 5,1913.

Application filed August 1, 1912. Serial No. 712,822.

To all whom it may concern:

Be it known that I, Tnnononn BUMANN, a citizen of the United States, residing at Litchfield, in the county of Montgomery and State of Illinois, have invented certain new and useful Improvements in Safety-Razors; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to cutlery, and more especially to safety razors; and the ob ject of the same is to produce an improved safety razor whereof the top bar of the frame gives a dish to the razor blade when the latter is inserted, and whereof the guard is adjustably mounted within the frame so that the cutting edge of the blade may be more or less protected and the user may have a close share or otherwise as desired.

The device is entirely free from pivots, and is made of but few pieces of metal in addition to the blade, and the details of construction are hereinafter more fully set forth and claimed, and shown in the drawings, wherein Figure l is a top view of this improved safety razor, with all parts complete, and Fig. 2 is a front elevation thereof. Fig. 3 is a central longitudinal sectional view on the line 3 3 of Fig. 2, and Fig. at is a sectional view on the line 4.4: thereof. Fig. 5 is a perspective view of the guard removed; and Fig. 6 is a plan view of the blank from which the frame is made,

The blank from which the frame of this improved safety razor is cut, is well shown in Fig. 6 wherein the dotted lines indicate the folds given the blank in the act of shaping it up. lVhile it may be possible to cut the handle integral with one end of the blank from which the frame is made, I preferably make it of a bowed piece of metal 1 and rivet it as at 2 to the extremities 3 of the frame blank. From this point of connection the side bars of the frame diverge upwardly as at a, thence extend outwardly in shoulders 5, and thence again upwardly in parallel lines as at 6 to form the ends of the frame, which latter are turned inwardly and connected by what I will call the cross bar 7 which constitutes the center of the metal strip from which the frame is made and which is dished or deflected slightly toward the handle as indicated. From What will be the rear edge of this cross bar are out two tongues 8 which in finishing up the article are turned under as shown; and when the blade B is inserted it is bent slightly throughout its length to conform with the curvature of the cross bar 7 and is slipped under the latter and into or over the tips of the tongues 8, so that when in place its cutting edge E projects beyond the front edge of the frame and its rear edge rests in the bends of the tongues as illustrated in Fig. 4.

N0 novelty is claimed for the blade B which will doubtless be simply a rectangular piece of steel sharpened along one edge as at E, and of such dimensions that it will fit within the frame and over the tongues 8, the thickness of the body of the blade being sufficient to give it some rigidity, and the curvature imparted thereto when it is bent slightly and placed within the frame maintaining this rigidity and preventing the cutting edge E from vibrating when the device is in use.

The blank from which the guard is made comprises a substantially rectangular piece of metal 10 notched out at its lower edge as at 11 and bent across its transverse center as at 12 so that the lips 18 at opposite sides of the notch 11 stand approximately parallel with the body. The latter has openings 14 cut through its bend 12 and extending thence upward to receive the tongues 8 when the guard is pushed into the frame; and the upper edge of the body has a series of guard fingers 15 which underlie the cutting edge E of the blade, and a pair of upwardly projecting hooks 1 6 at its ends which project 'beyond the corners of the blade so that-no matter what the adjustment of the guard the hooks always overlie the edge E and the fingers always project a trifle beyond the same to give the safety element to the device. The upper edge of said body also has a pair of outwardly projecting hooks 17 (best seen in Fig. 5) which engage the front edges of the ends 6 of the frame when the guard is pushed into place, and therefore prevent its movement to the rear in the act of using the razor.

The parts are assembled by springing the blade slightly and inserting it into the frame as above described, then holding the frame by the handle in one hand and taking the guard in the other and pushing it into the frame between its ends 6 with the lips 13 passing over the shoulders 5 and the body of the guard passing under the blade; and when the guard is pressed home its openings 14 pass over the tongues 8, its hooks 17 engage the ends 6 of the frame, and the guard comes to rest with the hooks l6 engaging the corners of the blade. At this time the latter stands with its cutting edge as near to the tips of the fingers as possible, and a close shave will be given when the razor is used. But if the user does not desire so close a shave, he has but to adjust the guard by slipping it toward him through the frame so that the fingers 15 and hooks 16 stand a little farther beyond the cutting edge E, as will be clear. After using this device in a manner not necessary to state, the parts are disconnected by pushing the guard out of place within the frame, then drawing the blade out of the latter and washing and laying away, or reassembling. It will not be necessary to amplify the sizes, shapes, proportions and materials of parts, further than as has been set forth; and I reserve the right to make changes in details such as do not depart from the principle of the invention claimed below.

l/Vhat is claimed as new is 1. In a razor, the combination with a handle, and a frame secured thereto and including an upper cross bar bent slightly toward said handle, and tongues extending from its rear edge and bent in under it; of a blade whose rear edge is adapted to be passed under said bar and between it and said tongues, and a guard of substantially U- shaped cross section having openings cut from its bend and adapted to pass over said tongues, the guard having fingers along its edge.

2. In a razor, the combination with a frame and a handle, and a blade; of means on the frame for engaging said blade, and a resilient guard of U-shaped cross section detachably and adjustably seated within said frame contiguous to the blade and having along its forward edge a series of fingers and at each extremity of the series an upturned hook to engage the edge of the blade and an o-utturned hook to engage the end of the frame. I

8. In a safety razor, the combination with a handle, and a frame secured thereto and including an upper cross bar bent slightly toward said handle, and tongues extending from its rear edge and bent in under it; of a blade whose rear edge is adapted to be passed under said bar and between it and said tongues, and a guard of substantially U-shaped cross section whose bend has openings cut from it and adapted to pass over said tongues, said guard having fingers along its edge and hooks at its extremities engaging the corners of the blades.

4. In a safety razor, the combination with a frame having a substantially rectangular opening through it, means for clamping a blade within said frame, and a handle secured to the lower portion of the frame; of a spring metal guard of U-shape in cross section slidably mounted through the frame and held therein by its expansion, the guard having fingers adjustable with reference to the edge of the blade.

5. In a safety razor, the combination with a frame having a substantially rectangular opening through it, means for clamping a blade within said frame, and a handle secured to the lower portion of the frame; of a bent guard of spring metal slidably and adjustably mounted within the frame and having fingers along that edge adjacent the edge of the blade and hooks at the extremities of the row of fingers adapted to engage the ends of the frame.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

THEODORE BUMANN.
