Gerhard Tittmann, of Foche, near Solingen, Germany. Safety-Razor.
No. 885,966. Specification of Letters Patent. Patented Apr. 28, 1908.
Application filed April 30, 1907. Serial No. 371,116

To all whom it may concern:

Be it known that I, Gerhard Tittmann, a citizen of Germany, and resident of Foche, near Solingen, Germany, have invented new and useful Improvements in Safety-Razors, of which the following is a specification. This invention relates to a safety razor in which the blade is removably held against the guard by means of a clamping plate which is tilted with its lower edge against the lower end of the blade. In this way the blade is securely clamped in position, while the guard may be entirely exposed if the razor is to be cleaned.

In the accompanying drawings: Figure 1 is a side view, partly in section, of my improved safety razor; Fig. 2 a side view showing the clamp plate detached; Fig. 3 a rear view of the razor-head with the screw stud in section; Figs. 4, 5 and 6 are side views of modifications; Fig. 7 an enlarged-side view of the modification shown in Fig. 6, and Fig. 8 a longitudinal section thereof.

In Figs. 1, 2 and 3 the handle g, of the razor is provided at its forward end with a threaded stem a, that is tapped into the eye of a perforated or toothed guard c. From guard c, extend laterally below the eye, a pair of opposed projections or studs k, each adapted to be received within a slot i, formed in a lateral wing h, of a clamp plate e. In this way clamp plate e, may be oscillated on studs k, to vary its inclination to the guard, while furthermore the clamp plate may be removed and the guard thereby become fully exposed for cleaning purposes. The cutting blade m, introduced between guard c, and plate e, projects with its lower cutting edge slightly beyond the lower edge of plate e. By tilting this plate with such lower edge against the lower end of the blade, the latter is thus securely clamped in position. The function of tilting plate e, is performed by the screw stem a, which passes through guard c, and bears with its end against the heel or upper end of plate e. In this way such upper end is pushed away from plate c, to correspondingly force its lower edge with adjustable pressure against the lower end of blade m.

In Fig. 4, the above construction for swinging and removably connecting plate e, to guard c, is reversed. In this modification clamp plate e, is provided with opposed lateral studs k2, while guard c, is provided with upturned slotted wings h2, adapted to removably engage said studs.

In Fig. 5, the wings h, are formed on clamp plate e, and the studs k, are formed on the guard, similar to the construction shown in Figs. 1–3. The function of tilting plate e, is not assumed by screw stem a, but by an additional set screw a′, that is tapped into guard c, and bears against the heel of plate e. The lateral slots i′, of plate e, are provided with upper recesses or notches, into which studs k enter when screw a′, is tightened against clamp plate e, so that the latter is prevented from slipping off guard c.

In Figs. 6, 7 and 8, there is fulcrumed to the top of guard c, at a3, a cam a2, which is adapted to bear against the heel of plate e, and thus force the latter, with its lower edge, against blade m.

I claim:

A safety razor provided with a guard, a clamp plate, laterally extending fulcrums on one of said parts, slotted wings on the other part removably engaged by said fulcrums, a perforation in the guard above the fulcrums, and tilting means passing through said perforation and adapted to engage the clamp plate, substantially as described.

Signed by me at Dusseldorf, Germany, this tenth day of April 1907.

Gerhard Tittmann.
