Edward B. Gibford, of Adrian, Michigan. Razor-Guard.
No. 889,183. Specification of Letters Patent. Patented May 26, 1908.
Application filed April 18, 1906. Serial No. 312,316

To all whom it may concern:

Be it known that I, Edward B. Gibford, a citizen of the United States, residing at Adrian, in the county of Lenawee, State of Michigan, have invented certain new and useful Improvements in Razor-Guards; 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, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to razor guards and consists in the construction and arrangement of parts hereinafter fully set forth and pointed out particularly in the claims.

The object of the invention is to provide a razor guard of simple and inexpensive construction, in which the arrangement is such as to render it readily attachable to or detachable from the blade, and wherein provision is made for adjusting the guard to the blade as desired and securely locking the guard at any point of adjustment.

The above object is attained by the structure illustrated in the accompanying drawing, in which :—

Figure 1 is a view showing applied to a razor blade a guard involving my invention. Fig. 2 is an elevation of the parts detached from the blade. Fig. 3 is a transverse section as on line 3—3 of Fig. 1. Fig. 4 is a side elevation opposite to that shown in Fig. 1. Fig. 5 is a perspective view of the back plate adapted to be mounted upon the blade of the razor which supports the guard plate and upon which said guard plate is adjustably mounted.

Referring to the characters of reference, 1 designates the back plate which is equal in length to the blade 2 of the razor, and which is provided at each end with a laterally extending arm 3. Formed upon the outer edges of said arms and curving upwardly and inwardly are the lips 4 which form slide-ways between their under faces and the upper faces of said arms, adapted to receive the projecting end portions 5 of the guard plate 6, and in which said projecting end portions are adapted to reciprocate.

Extending inwardly from the ends of the arms 3 are the brackets 7 upon which are pivoted the eccentric levers 8 adapted to engage the inner edges of the projecting end portions of the guard and bind them in the ways formed by the lips 4, so as to lock the guard against movement as shown in Figs. 1 and 2.

The back plate 1 is secured to the blade of the razor by means of the opposed spring jaws 9 which extend inwardly from the opposite edges of said plate and whose free edges converge so as to bind upon the blade of the razor with sufficient tension to hold the plate in position thereon, the blade of the razor being entered between said jaws by inserting it endwise.

The guard plate 6 is provided along its outer edge with a series of teeth 10 which project beyond the edge of the razor blade to prevent cutting the face of the user, as will be well understood in the art. The extent of the projection of the teeth of the guard beyond the edge of the blade, determines the character of the work performed and is varied according to the conditions of the face and beard. Where it is desired to acquire a smooth shave only, the teeth are made to project well beyond the blade, but where a close shave is desired, the teeth of the guard are retracted to enable the blade to cut closer to the face. These various degrees of adjustment are accomplished by sliding the end portions 5 of the guard in the ways formed by the lips 4. To allow a movement of the guard, the eccentric levers 8 are swung inwardly to release the end portions 5 thereof as shown by dotted lines in Fig. 1. After the guard has been adjusted, it is locked in place by throwing said levers to the position shown by solid lines in Figs. 1 and 2, whereby the eccentrics are caused to bind the extensions of the guard plate in their respective ways.

This construction of razor guard is very simple and inexpensive, and is of a character to enable it to be readily cleaned after use, the arrangement of the parts enabling it to be readily mounted upon a blade and the guard quickly adjusted according to the width of the blade and the desire of the user.

Having thus fully set forth my invention, what I claim as new and desire to secure by Letters Patent is:—

1. In a razor guard, the combination of the back plate having clamping jaws adapted to embrace the blade and having laterally extending supporting arms provided with projecting brackets, there being upon each of said arms a slide-way, a guard plate having extensions adapted to cater said ways, and the eccentric levers pivoted on said brackets for locking said extensions therein.

2. In a razor guard, the combination with the back plate having means of attachment to the blade, and having at each end a laterally extending arm provided with a projecting bracket, there being upon each of said arms an open slide way, and an eccentric lever pivoted on the bracket thereof opposite the opening in said way, a guard plate having extensions adapted to slide in said ways and to be engaged by said eccentrics to lock the guard plate against movement.

In testimony whereof, I sign this specification in the presence of two witnesses.

Edward B. Gibford.
