To all whom it may concern:
Be it known that I, Eugene G. Mergenthaler, a citizen of the United States, residing at Baltimore, State of Maryland, have invented certain new and useful Improvements in Safety-Razors, of which the following is a specification.
My invention relates to safety razors and more particularly to improvements in the safety razor construction shown in Patent No, 973,533, granted to me October 25, 1910. One of the objects of the present invention is to provide an improved clamp for the working portion of the razor tape so that the clamp may be readily manipulated when the working portion of the blade is to be changed and so that the clamp may be securely held in place when the razor is used in shaving.
A further object of the invention is to provide a simple adjustment guard member for the blade.
Another object is to form a blade magazine in the frame and integral therewith.
The above and other objects and the novel features of my invention will be apparent from the following description taken in connection with the drawing, in which:
Referring to the drawing, the frame of the razor comprises a hollow triangular member having the inclined sides
The tape is put on the market in capsules or magazines one of which is shown in place in the cavity of the supporting frame. The magazine comprises two separable cup-like members
The inside section
The outside of the other side member
The clamping member for holding the blade
The bottom of the magazine
The front face of the portion
As shown in
When it is desired to obtain a new cutting edge the plate
In order to lock the clamping member in position the handle member
From the foregoing description it will be seen that the blade is firmly clamped in position and may be readily unclamped by a simple manipulation of the handle part of the device. Furthermore, the fact that the handle member is readily detachable has the added advantage that it may be put in a case and it will require a much smaller case than a razor with a permanently attached handle.
While I have shown and described the device in detail I do not wish to be limited to the exact construction herein disclosed as it is apparent that numerous changes may be made without departing from the spirit of the invention.
Having thus described the invention what is claimed and desired to be secured by Letters Patent is:
1. In a safety razor, the combination of a frame having a guideway at the rear thereof and a blade support at the upper end of the guideway, a blade magazine located below said support and in front of said guideway, a clamping member having a stem fitting said guideway and a part disposed adjacent the blade support and capable of clamping a blade against said support, and a handle member for said frame having a part adapted to interlock with the lower end of said stem, a partial turn of said handle member being adapted to actuate said clamping member to clump the blade against the support.
2. In a safety razor, the combination of a frame, a blade support thereon, a blade magazine on the frame, and means for retaining a blade in cutting position on said support comprising a blade engaging member and a handle member capable of releasably locking said blade engaging member in place, said blade magazine being disposed between the blade support and said releasable handle member.
3. In a safety razor, the combination of a frame having a supporting surface for a razor blade, a guard located beneath said surface and adjustable with respect thereto, a clamping member coöperating with the upper side of said surface to hold a blade in place thereon, and a cylindrical handle part for said frame having means interfitting with a part of said frame and other means for engaging and securing said clamping member in its clamping position.
4. In a safety razor, the combination of a frame comprising side members and a top member, said top member comprising the blade supporting part, a guard pivoted between the side members, a clamping member coöperating with the blade supporting part, and a handle having means for releasably securing said clamping member in position.
5. In a safety razor, the combination with a frame provided with a blade supporting surface and a guard, of a blade magazine carried by said frame, a blade having a part coiled in said magazine and a part on said supporting surface, a blade clamping member capable of engaging said blade to clamp it against said surface, and a handle for said frame, said handle and frame having portions interfitting telescopically, and said handle and clamping member being provided with readily engageable and disengageable interlocking parts to secure the clamping member in clamped position, and also to secure said handle and frame together with said portions thereof in telescopic relation.
6. In a safety razor, a blade support, a clamping member coöperating with said blade support, a guard member pivoted beneath the blade support and having a depending member, and a device carried by said blade support and capable of engaging said depending member on the guard to hold said guard in any one of a number of adjusted positions.
7. In a safety razor, the combination of a frame having a top member provided with a blade supporting surface on the upper side thereof and a hollow, vertical guide-way extending from near the bottom of said frame to the top thereof and terminating at the rear of said blade supporting surface, a guard below said supporting surface, a blade clamping member having a part coöperating with said top member and a stem fitting said hollow guide-way, and means coöperating with said stem to lock the clamping member in clamped position.
8. In a safety razor, the combination with a blade supporting member and a guard, of a clamping device having a stem fitting a vertical guide-way in the rear portion of the blade supporting member, said stem having a shoulder thereon, and a detachable handle having a part telescopically fitting a part of said blade supporting member and having a shoulder coöperating with said shoulder on said stem to secure said handle to said blade supporting member and also to secure the clamping bar in clamped position, said shoulders being engageable and disengageable to clamp and unclamp said parts by only a partial turn of the handle.
9. In a safety razor, a frame, a guard member pivoted to the frame and having a curved tongue at the rear thereof and a projection on the frame capable of engaging the convex surface of said tongue to retain the guard member in any one of a number of adjusted positions.
10. In a safety razor, the combination with a frame of a guard member pivoted thereon, said guard member having a notched tongue thereon, and a projection on said frame coöperating with the notched tongue to retain the guard member in an adjusted position.
11. In a safety razor, the combination of a frame having side members and a top member, the top member constituting a blade support, said side members converging downwardly, a stem on said frame at the lower ends of said side members, a clamping member coöperating with said top member and having a stem the end of which is located adjacent the stem on the frame, and a handle fitting the stem on the frame and engaging the stem on the clamping member.
12. In a safety razor, the combination with a blade support of a clamping member coöperating with said blade support, said clamping member having a stem provided with a lug, and a detachable handle for said blade support having a cam groove capable of engaging said lug to lock said clamping member in clamping position.
13. In a safety razor, the combination of a blade support, a clamping member coöperating therewith, a stem attached to said clamping member and having a lug thereon provided with an under-cut edge, and a detachable handle member for said blade support having an under-cut edge coöperating with the under-cut edge on the lug of said stem to lock said handle and stem together, and yieldable means for holding said under-cut edges in their locked relation.
14. In a safety razor, the combination with a blade holder having a cavity, of a blade magazine fitting said cavity, and means for spacing part of said magazine from the wall of said cavity for the purpose described.
15. A capsule for razor tape having an outlet slot in its side wall and flanges at opposite ends for the purpose set forth.
16. In a safety razor, the combination of a blade holder having a cavity provided with a slot in one wall, a blade magazine fitting said cavity and having a slot in its side wall registering with said slot in the wall of the cavity, means for locking the magazine in place in the cavity, and means for holding the magazine apart from the wall of the cavity for the purpose set forth.
