To all whom it may concern:
Be it known that I, John Elmer Parkison, a citizen of the United States, residing at Colorado Springs, in the county of El Paso and State of Colorado, have invented certain new and useful Improvements in 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, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.
My invention relates to improvements in razors of the safety type in which a detachable blade is employed.
My object is to provide a device which shall be exceedingly simple in construction, economical in manufacture and the blade of which is so inexpensive that it may be discarded or thrown away when it becomes dull.
An exceedingly important feature of my improved device, consists in the fact that the guard is so located that there is a continuous slot immediately in front of the cutting edge of the blade or between this edge and the guard. By reason of this construction it is distinguished from razors of the safety type in which a toothed guard is overlapped by the blade which to a certain extent prevents the use of the device except when the blade occupies a position at right angles or approximately at right angles to the direction of travel or movement. If a razor having a toothed guard is moved when held with its blade at an oblique angle to the direction of movement, the teeth of the guard moving in front of the blade, press the beard downwardly and thus interfere with the action of the blade thereon. My object is to overcome this difficulty by leaving a continuous slot or uninterrupted space extending the entire length of the edge of the blade and in front of the same thus making it practicable to move the blade over the face when held at an oblique angle to the direction of movement, thus permitting a shearing drawing cut, which is exceedingly advantageous when any cutting instrument is employed as is well known. By leaving a clear space in front of the edge of the blade its entire length, the beard has an opportunity to assume an erect position in front of the edge of the blade after the guard has passed over it, thus allowing the blade to act thereon under the most favorable conditions, or in the same manner as the blade of an ordinary razor, not of the safety type. At the same time my construction is such that the user, by reason of the construction aid arrangement of the guard, has all the advantages which can be obtained from any safety type of razor so far as freedom from danger of cutting the face is concerned.
My improved construction of safety razor has still another advantage, since the handle, the guard and the backing, may all be formed or stamped from a single piece of sheet metal, thus making the device of exceedingly simple and economical construction as heretofore intimated.
Briefly stated the construction consists of a tubular handle, a backing plate bent to occupy a position at an oblique angle to the handle, a tubular guard bent below the backing plate and having its free extremity located a short distance in front of the backing plate; a thin blade placed upon the backing plate and having recessed extremities to receive lips formed on the backing plate whereby the blade is held in place; and a clasp pivoted at one extremity and adapted to pass over the blade and the backing plate, the said clasp engaging the blade on one side and the backing plate on the other, whereby the blade is held securely in place and with its cutting edge a short distance in the rear of the free edge of the guard.
Having briefly outlined my improved construction, its function and the advantages or objects sought to be obtained therefrom, I will proceed to describe the same in detail, reference being made to the accompanying drawing in which is illustrated an embodiment thereof.

Having thus described my invention, what I claim is:
1. A razor having a handle, a backing plate supported by and extending transversely across one end of the handle, means for connecting a razor blade to said plate with its cutting edge projecting beyond the same, a guard with a straight edge, and means for supporting the guard with said edge parallel to but wholly separated at all points from the edge of the razor blade.
2. A razor comprising a handle, a backing plate occupying a position transversely of the handle, a guard having a straight edge wholly separated at all points from the backing plate, and means for supporting the razor blade on the backing plate with its cutting edge forward of the latter and parallel to but at all points away from the edge of the guard.
3. A razor comprising a handle, a backing plate provided with end lips formed integral with the plate and extending outwardly therefrom on one side, a blade having end recesses which the lips engage, the recesses being open at the ends of the blade and means for holding the blade in place on the plate.
4. A razor comprising a handle, a backing plate, a blade mounted on the plate, a clasp for holding the blade in place, the clasp being pivotally connected at one end of the backing plate and composed of two separated parallel members adapted to swing over and straddle the rear edge of the backing plate and blade whereby it is made to engage both ends of the latter.
5. A razor comprising a handle, a backing plate connected with the handle and extending at an angle thereto, the plate having end lips, a blade having end recesses engaged by the lips of the plate, a clasp composed of two parallel members pivoted to the plate to swing over the rear edges of the plate and blade, the clasp members being separated to engage said parts and hold them in operative relation, and a guard below and in front of the cutting edge of the blade.
6. A razor comprising a handle, a backing plate connected with the handle and provided with end lips, a blade having recesses engaged by said lips, a clasp pivotally connected with the plate at one end to swing over the rear edge of the backing plate and blade to hold the latter in place, and a guard connected with the backing plate, the said guard comprising a tubular member located below the cutting edge of the blade and having a longitudinal opening adjacent the edge of the blade forming an uninterrupted space between the edges of the blade and guard.
7. A razor comprising a handle, a backing late, a tubular guard between the plate and handle, the said guard being connected with the backing plate and extending downwardly below the cutting edge of the blade, the guard having an edge located remote from the backing plate and occupying a position directly in front of the cutting edge of the blade, and a clasp pivotally connected with one end of the backing plate and adapted to swing over the rear edge of the backing plate and blade whereby the two parts are connected in operative relation.
8. A razor having a handle, a backing plate, and a guard formed from an integral piece of sheet metal, a blade detachably connected with the backing plate, and a clasp pivotally connected with the backing plate at one end and composed of two separated parallel parts to swing over and straddle the rear edge of the backing plate and blade for holding the blade in place.
9. A razor comprising a tubular handle, a backing plate extending on both sides of the handle and occupying a position at a suitable angle thereto, a tubular guard connected with the backing plate and occupying a position below the latter, the handle adjacent the backing plate being cut away to make room for the guard, the latter having a smooth edge located directly in front of the cutting edge of the blade, the edges of the blade an guard being separated by an uninterrupted space.
10. A razor comprising a handle, a backing plate, a guard, a blade engaging the backing plate, and a clasp composed of two separate parallel members, the clasp being pivoted to one end of the backing plate to swing over and straddle the rear edges of the plate and blade to hold the blade in place.
11. A razor comprising a handle, a backing plate, a guard mounted on the backing plate, and a clasp composed of two separated parallel parts, said clasp being pivoted at one of the lower front corners of the backing plate to swing over and straddle the rear edges of the said plate and blade whereby the latter is locked securely in place.
12. In a razor, the combination of a handle, a backing plate connected with the handle, projections on the backing plate, a blade provided with end recesses which the projections of the backing plate engage, and a clasp provided with two separated parallel parts for holding the blade in place, the said clasp being pivotally connected with one end of the backing plate to swing over and straddle the rear edges of the backing plate and blade, the clasp engaging the blade and plate on opposite sides whereby the blade is held securely in place on the plate.
13. A razor comprising a tubular handle, a backing plate connected with the handle, the latter being cut away adjacent said backing plate, a tubular guard arranged adjacent said cut away portion of the handle and having a smooth edge directly in front of the backing plate, said edge being separated throughout its length from the backing plate, and a blade mounted on the backing plate and having its cutting edge projecting into the space between said plate and guard, said cutting edge being out of contact throughout its length with the smooth edge of the guard.
14. A razor comprising a handle, a backing plate, a guard occupying a position between the backing plate and the handle, the handle, backing plate and guard being formed from an integral piece of sheet metal, a blade mounted on the backing plate and having end recesses, the backing plate having lips engaging the recesses of the blade, and a clasp for holding the blade in place on the backing plate, the said clasp being pivoted to one end of the backing plate and composed of two separated parallel members which swing over and straddle the rear edges of the backing plate and blade, the clasp being constructed to engage the plate and blade on opposite sides whereby the blade is held securely in place.
In testimony whereof I affix my signature in presence of two witnesses.
