AT'I'ILIO EUGENIO TASCA, OF EAST PROVIDENCE, RHODE ISLAND.

COMBINATION SAFETY RAZOR AND STROPPER.

Application filed January 26, 1922. Serial No. 531,884.

To all whom it may concern:

Be it known that I, A'r'rimo EUGENIO TASCA, a citizen of the United States, residing at 128A Central Avenue, East Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in a Combination Safety Razor and Stropper.

In many forms of safety-razors previously devised, owing to the fact that no provision is made for the stropping of the blade, the cutting edge quickly becomes dull and useless; also, the razor blade must be removed from the blade holder to clean it after each shaving operation, causing thereby, a loss of time and incurs the danger of cutting the operator or ruining the cutting edge of the razor blade.

In other forms of safety-razors in which it is possible to strop the blade, the action is complicated, in that the blade must be removed from the blade holder; is uncertain and of doubtful value; and in still other forms of safety-razors the stropping must be done mechanically on a special designed stropping surface which is often cut and rendered useless and many times ruining the cutting edge of the blade.

My invention relates to a device forovercoming these faults; first, by simplicity of construction, in that it will securely hold the razor blade in the proper position for the shaving operation, it will permit thecleaning of the blade and also the stropping of same by hand pressure on any stropping surface and this object attained with the same handle that holds the blade holder during the shaving operation, without the removal of the razor blade from the blade holder.

The object of my invention is first, to hold the razor blade securely, second, to have a movable safety guard held firmly in the proper relation to the cutting edge of blade, thus rendering it a safety razor, third, to have a movable safety guard that will fold out of the way, permitting the cleaning and wiping of the cutting edge of blade, fourth, to place the movable safety guard in such a position as will render it poss1ble to insert the razor blade holder and guard, with blade therein, into the stropping slot pro vided on the shaving and stropping handle so as to be able to strop theblade by hand pressure on any stropping surface.

This stropping is highly essential to maintain the efliciency and keenness of the razor blade and this without removing the blade from the blade. holder will enable the operator to retain the blade in the holder for continuous use or until the blade outlives its usefulness; thus it will be seen that being a simple, compact, practical and efficient device containing but few parts, it is a distinct improvement over other types of safety-razors and stropping devices previously devised, in that it saves time in the shaving operation, removes the danger of injury to the operator or to the; cutting edge of the razor blade, and permits the stropping of the blade by hand pressure on any stropping surface without removing the blade from the blade holder and with the least possible effort on the part of the operator.

Having invented this combination safetyrazor and stropper with the above stated improvements which I believe satisfactorily overcomes objectional features of prior art, my device may be described as having three parts; a combined razor blade holder and safety guard, a blade and a combination shaving and stropping handle, consisting of mechanism illustrated in the accompanying drawings, in which;

Fig. 1,. is a plan view of the back of the blade holder with guard guarding the blade; Fig. 2, is an end view of the blade holder and guard with blade therein showing operation of holder and guard; Fig. 3 is another plan view of back of blade holder and guard with blade therein and guard folded back; Fig. 4, a plan view of the inside of blade holder; Fig. 5, a plan view of the front of blade holder and guard with blade therein; Fig. 6, a plan view of the blade; Fig. 7, a side elevation showing blade holder with blade therein and guard. folded back partially inserted in the stropping slot on handle; Fig. 8, is a vertical end viewof the entire device assembled for shaving.

Similar numerals refer to similar parts throughout the drawings.

The blade holder comprises two

jaws

2 and 4 connected together by hinge 6 on which they open and close, 4 being the front jaw and 2 the rear aw. Jaw 4 is slightly wider that jaw 2 so as to prevent any vibration on the part of the blade 12 and to hold the same with greater rigidity for the shaving operation, See Fig. 2.

11 are the blade retaining lugs which fit the holes 16 in the blade 12. 10 are the holes in the rear jaw 2 in which the lugs 11 fit when the jaws 2 and 4: are brought together.

17 the center hole in

blade

12 and 9 the center hole in jaw 2 freely allow the passage of threaded post 15 on handle 13 to engage the center hole 8 in jaw 4 which is drilled and threaded at an angle adapted to tilt the blade holder and guard with blade therein in the proper position for shaving.

1 is the safety guard connected to jaw 2 by hinge 7 and is adapted to move to position guarding the blade, as in Fig. 1, and also fold back to position between the flanges 5 on jaw 2, as in Fig. 3.

The guard 1 when folded back between flanges 5 has a longitudinal groove 3 exposed which co-operates with and assists groove 3 on the outside of front jaw 4 when the blade holder with guard folded back, and blade therein, is inserted into slot 14 on handle 13 for stropping purposes, as in Fig. 7

In the operation of the device, assuming that there is no blade in the holder, the operator, lifting up the guard 1 in Fig. 1, also liftsup jaw 2 to which the guard is connected by a hinge, opening the blade holder as in Fig. 4. he now places blade 12, Fig. 6 on lugs 11, being careful to fit holes 16 on said lugs 11; he then closes the jaws of the blade holder, with blade between them, and then moves safety guard to position forward or to where it guards the cutting edge of blade, as in Fig. 1; next he passes the threaded post 15 on end of the combination handle 13 through the hole 9 in rear jaw 2 and engaging threaded hole 8 in front jaw 4 he screws handle in tightly being careful to slightly tilt the handle towards the cutting edge of the blade, this not only bringing the two jaws of the blade holder together with the blade between them, but also brings the safety guard into the proper relation to the cutting edge of the blade for safety shaving.

If the operator wishes to clean or strop the cutting edge of the blade he unscrews the handle 13 in Fig 8, folds the safety guard back until it rests between the flanges 5 on the rear jaw 2, as in Fig. 3, and then slides the entire device into the slot 14 in handle, as far as it will go; in this position the cutting edge of blade can be freely cleaned or stropped by hand pressure on any stropping surface. and thus it will be seen that the device can be used for shaving and strapping without removing the blade from the holder. When the blade becomes dull or another is desired the operator reverses the operation above described.

Having thus described my invention and its operation what I claim as new and wish to secure by Letters Patent of the United States is:
