SPECIFICATION forming part of Letters Patent No. 434,187, dated August 12, 1890.
Application filed May 1, 1890. Serial No. 350,187. (No model.)
To all whom it may concern:
Be it known that I, Henry B. Leach, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Safety-Razors, of which the following, taken in connection with the accompanying drawings, is a specification.
The object of my invention is to provide a safety-razor with a sliding front or blade-holding plate, to which is attached a guard, said guard being made integral with or rigidly attached to the front or blade-holding plate.
Another object of my invention is to provide a handle that can be easily attached to or detached from the razor-frame.
I attain these objects by the mechanism shown in the accompanying drawings, in which—
Figure 1 is an elevation. Fig. 2 is an enlarged longitudinal vertical section. Fig. 3 is an enlarged sectional view of the handle removed. Fig. 4 is an enlarged rear view of the frame. Fig.5 is an enlarged front view of the frame. Fig. 6 is an enlarged sectional view of the frame or blade-holder.
Similar letters refer to similar parts throughout the several views.
Referring to the drawings, A, Fig. 4, shows the frame or blade-holder with an open or skeleton back, having ends A′ A′, bent at right angles with the back.
A2 A2, Figs. 2, 5, and 6, are parts of the ends A′ A′, bent at right angles with the ends A′ A′.
a a, Fig. 4, are raised surfaces on the back of frame A.
a′ is an aperture in the back of frame A.
a2 a2 are clips on the ends of A′ A′.
a3 a3 are slots in the parts A2 A2.
B is the handle with the rod b.
b′ is a thumb-screw.
b2 is a part of the rod b, bent or cast at right angles with said rod.
C is a clamping-screw with its shoulder c.
C′ is a support for the clamping-screw C.
D is the blade.
E is the sliding front or blade resting plate and guard with upper part bent at right angles with said plate.
E′ E′ are the adjusting-screws.
E2 E2 are flanges bent up at right angles with the sliding front plate.
e is a pin for supporting the sliding front plate and upon which it slides.
e′ is a longitudinal groove upon the guard E.
The blade D is held in the frame against the sliding front plate by the clips a2 a2 and the clamping-screw C with its shoulder c. The blade D is held in one position. To adjust the blade as it is worn away by honing, the sliding front plate E is moved up by the adjusting-screws E′ E′ on a line parallel to the back of the frame or blade-holder. Said screws E′ E′ work in slots a3 a3 in the parts A2 A2. The screws E′ E′ have a groove in their heads, that prevents them from moving up or down. The lower parts of said screws are screwed into the bent portions of the sliding front plate. By turning the screws E′ E′ the guard E can be adjusted to blades of different widths, the front plate sliding on the pin e. The groove e′ on the guard E allows plenty of space below and behind the edge of the blade for the passage of the cut beard, &c. The bent portions of the front plate, bearing against the back of the frame, keep it in position and relieve the strain upon the screws E′ E′.
The second part of my invention relates to my improved handle B, Figs. 1, 2, and 3, showing a tube with a rod b, that screws into a non-reciprocating thumb-screw b′. b2 is a short angular part in the rod b. To attach the handle B to the frame A, the part b2 is inserted into the aperture a′ in the back of frame A. A few turns of the thumb-screw b′ will clamp the handle firmly to the frame or blade-holder, the angular part b2 to the inside, and one end of handle B to the outside, as shown in Figs. 1 and 2. The support C′, having a recess on its lower end, embraces the greater part of the aperture a′, as shown in Fig. 5, and serves to prevent the rod from turning when inserted into said aperture a′. The raised surfaces a a act as guides to keep the handle B central.
1. In a safety-razor, the combination, with a razor-blade and its frame or holder, of a sliding front plate and guard, against which the blade is held in a fixed position by end clips, and a suitable clamping device, substantially as described, and for the purpose set forth.
2. In a safety-razor, the combination of the razor-blade, its frame or holder, having clips a2 a2, clamping-screw C, with its shoulder c, sliding front plate and guard E′, adjusting-screws E′ E′, and supporting-pin e, substantially as described, and for the purpose set forth.
3. In a safety-razor, the combination, with a frame or blade-holder, of a removable handle provided with a rod having an angular part and an actuating-screw, said angular part arranged and adapted to be inserted endwise into an aperture of the same diameter as the rod and angular part in the back plate of the frame or blade-holder, one end of the handle bearing against the outside of the back plate of the frame or blade-holder and the angular part of the rod bearing against the inside of said back plate, substantially as described, and for the purpose set forth.
In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this the 29th day of April, A. D. 1890.
Henry B. Leach.
