' SAFETY RAZOR Filed July 22, 1955 Lee B. Lane INVENTOR A TORN EY Patented May 5, 1936 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to safety razors and has for its primary object the provision of a safety razor embodying a novel arrangement of elements particularly adapted for quick disassembly and cleaning as well as for convenient shaving or stropping of the blade thereof.

A further object of my invention resides in providing a safety razor guard embodying the features of simple construction and economy of manufacture, the use of which assures the prevention of accidentally cutting the skin.

Another object of my invention is to provide a razor, the guard of which will obviate the annoyance of clogging by the lather or other shaving preparation, which may be instantly removed by a simple rinsing.

The invention will be fully and comprehensively understood from a consideration of the following detailed description when read in connection with the accompanying drawing which forms part of the application, with the understanding, however, that the improvement is capable of extended application and is not confined to the exact showing of the drawing nor to the precise construction described and, therefore, such changes and modifications may be made therein as do not affect the spirit of the invention nor exceed the scope thereof as expressed in the appended claims.

In the drawing:

Fig. 1 is a side elevational view of my assembled safety razor at a slightly enlarged scale.

Fig. 2 is a top elevational view of the razor as shown in Fig. 1; and

Fig. 3 is a perspective view of the safety guard of my invention apart from the razor.

Referring now to the drawing for a more detailed description thereof, the numeral 4 indicates the blade of my razor which in its preferred form is of the hollow ground type, which has a substantial thickness at its rear portion 5. Into this portion a tapped hole 6 is out which provides a means of attaching the razor handle 1. At one end of the handle 1 is formed a shank 8 of reduced diameter which, being threaded, is adapted to screw into the hole 6.

A second tapped hole 9 is' out into the blade 4 at one end thereof, into which the shank 8 of the handle 1 may be fitted to facilitate the stropping of the blade 4 according to the method usually employed for straight razors. It is to be noted here that other means than the tapped holes and threaded shank of attaching my handle I to the blade 4 may be employed without departing from the spirit of my invention.

The safety guard of my razor is shown more clearly in Fig. 3 and comprises a hub or collar I ll having a bore ll extending axially thru same,

into which the handle shank 8 may be inserted before attaching same to the blade 4. Extending integrally from the hub I0 are the legs l2 which form part of the safety guard frame, the front bar l3 of which extends from end to end of the legs l2 to form a symmetrical triangle at the apex of which is the hub Ill. The front bar 53 is arranged on the guard frame so that when the guard is assembled to the razor blade 4 the front bar In is disposed just forward of the cutting edge of the blade 4 and in spaced parallelism with same. This latter arrangement provides the required safety against accidental cutting as well as preventing the clogging at this region of the razor. The spacing of the front bar I3 from the cutting edge of the blade 4 is controlled by the projections I4 which are formed on the legs 12 adjacent the juncture of the front bar 13 such as by extruding or indenting a portion of the legs l2. The razor guard is held from turning on the shank 8 partially by the inclination of the top surface of its hub H], which being of a greater thickness at its rear portion counteracts the tendency of turning. The position of the safety guard on the blade is further assured by the provision of the pin M which projects from the hub ID to engage in a recess I5 appropriately formed in the blade 4.

What is claimed as new is:

1. A safety razor comprising a rigid hollow ground shaving blade, a handle detachably secured to said blade, and a guard held against said blade by said handle, said guard comprising a closed triangular loop including a straight leg adjacent and parallel to the cutting edge of the blade.

2. A safety razor comprising a rigid hollow ground shaving blade, a handle detachably secured to said blade, and a guard held against said blade by said handle, said guard comprising a closed triangular loop including a straight leg adjacent and parallel to the cutting edge of the blade, and oblique legs having projections spacing the straight leg of the guard from the cutting edge of the blade.

3. A safety razor comprising a rigid hollow ground shaving blade, a handle detachably secured to said blade, a, guard held against said blade by said handle, said guard comprising a closed triangular loop including a straight leg adjacent and parallel to the cutting edge of the blade, and oblique legs having projections spacing the straight leg of the guard from the cutting edge of the blade, said blade having a recess and said guard including a pin in said recess to aid in maintaining the proper position of said guard.
