Jan. 5, 1932. JIB. RHODES SAFETY RAZOR AND BLADE THEREFOR Filed April 7, 1930 ENTOR Y Y 74/? E TORNEYS Jay 2 ff/maacs Patented Jan. 5, 1932 UNITED STATES PATENT OFFICE JAY ."B. BHODES, OF KALAMAZOO, MICHIGAN; FLORA RHODES ADMTNISTRATRIX OF SAID JAY IB. RHODES, DECEASED SAFETY RAZOR AND BLADE THEREFOR Application filed April 7,

The main objects of this invention are: First, to provide a safety razor which is very convenient to use and one in which the blade can be quickly inserted and removed and at the same time is verysecurely retained and held in position for effective use.

Second, to provide a structure of this type in which there are no screws or adjustable parts.

Third, to provide a structure having these advantages which may be very economically produced.

Fourth, to provide an improved safety razor blade which may be quickl inserted or removed from its holder and W en inserted is retained in a most effective position for use without adjustment of parts of the holder.

Objects relating to details and economies of my invention will appear from the description to follow. The invention is defined and pointedout in the claims.

A structure which is a preferred embodiment of my invention is illustrated in the accompanying drawings, in which:

Fig. 1 is a perspective view of my improved safety razor with the blade in position therein.

Fig. 2 is a fragmentary'side elevation with the blade removed.

Fig. 3 is a fragmentary section on line 3-3 of Fig. 1 illustrating the manner of removing the blade, the blade being shown in partially projected position by dotted lines.

Fig. 4 is a plan view of the blade.

My improved safety razor comprises a handle 1 to which I permanently secure the combined base plate and guard member 2 curved upwardly at 21 and having curved guard teeth 3 at its forward edge.

The blade holder plate 4: is supported in spaced relation to the plate 2 to receive the blade 5 between them.

The holder plate 4 and the base plate or member 2 are connected at their rear edges by the integral spaced outwardly curved loops 6. The finger 7 having a hole 71 therein projects rearwardly from the holder plate between theseloops, this finger being directed inwardly as clearly shown in Figs. 2 and 3. The hole 71 permits the riveting of the handle 1930. Serial No. 442,206.

the members, supporting the blade against.

longitudinal movement within the holder.

The blade is provided with a hole 9 into which the finger 7 projects, the finger engaging the rear edge of the hole, therebypreventing forward movement of the blade.

The finger also applies a bending stress to the blade, as shown in Fig. 3, so that the forward part of the blade 1s held against the inner side of the holder plate 4 and centrally of the blade against the upper side of the plate at 21, thereby allowing the flexing of the cutting edge w ich enhances the smooth shaving with the razor.

The blade is also provided with longitudinally projecting finger pieces 10 disposed at its rearend, these finger pieces projecting beyond the base and holder plates so that the blade may be grasped thereby when in the holder.

To insert the blade, it is only necessa to introduce it between the base and ho der plates and draw it rearwardly until its rear edge engages the loop-like supports 6 in which position the spring of the blade will engage the rear edge of the opening 9 with the finger 7, the blade then being held under spring tension as described.

To remove the blade, its tongue 8 is pushed downwardly as indicated by dotted lines in Fig. 3 to disengage it from the finger 7 when the blade may be pushed forwardly and grasped by its finger pieces 10 for complete removal.

My im roved razor is made up of two pieces of materlal, the handle constituting one part and the holder parts the other. There are no screws or adjustments required to properly hold the blade. 7
