SAFETY-RAZOR.

Patented June is, 1916.

Application filed October 5, 1915. Serial No. 54,188.

Be it known that I, Rononro MARI, a subject of the King of Italy, and resident of No. 1132 San Martin street, Rosario de' Santa F, Republic of Argentina, have invented certain new and useful Improvements in Safety-Razors, of which the following is a specification. V

. This invention relates to a novel type of safety razor and has for object to provide certain improvements which tend to render its use more practical while cheapening at the same time its construction. I

' The invention refers more particularly to safety razors which may be used in the same way asordinary razors, that is to say, safety 'razors provided with the usual form of handle or shell and therefore adapted to be handled as a common razor. of razor offers the advantage that the hand always assumes its usual position and that the cutting edge may accommodate itself much better to the face, so that the operation of shaving requires less time and may be carried out more safely and perfectly.

A further advantage of the safety razor according to this invention is that the same may be mounted and dismounted speedily and without any difliculty, while at the same time, owing to the particular arrangement of its different parts, it is not liable to get dirty as there are no inner or hidden parts to which the soap might gain access. This latter fact constitutes a serious drawback of most of the known safety razors, in connection with which considerable time is lost in cleaning the same during use. p

A further object of this invention is to provide means for adjusting the razor, so as to allow the same to readily accommodating itself to more or less strongly developed beards, this purpose being realized in a very simple manner, as will hereinafter be fully explained.

In order that this invention may be readily and clearly understood and carried into practice, a preferred form of construction of the same has been represented in the annexed drawings, wherein:

Figure 1 is a plan view of a double metallic comb, being one of the several parts which. constitute the safety razor in accordance with the present invention. Fig. 1 is a similar view of the cutting blade provided, as in most of the known safety razors, with two cutting edges, inorder to prolong This type its use. Fig. 1 is a similar view of the main or body part of the razor, provided with its corresponding handle, adapted to be par]- tially folded. Fig. 1 is a view similar to that of Fig; 1 but at right angles thereto.

Fig. 2 is a sectional view of the parts shown" in Figs. 1, If and 1 in the superposed posltion occupled thereby when the apparatus is to be used. Fig. 3 is an upper view of the operating part of the safety razor, with the severalparts 1n superposed position readyfor being fixed in place. Fig. 4 is a view similar to that of Fig. 3, the razor being,

ready for use. Fig. 5 is a View, on a larger scale, of the particular device employed for connecting the parts together, and finally F g. 6 illustrates a longitudinal section through the double combjof Fig. 1.

In all figures. of the drawings, similar letters of reference indicate like parts.

"The main part or body piece of. the safety razor consists of a metallic frame to which ls-pivoted in any suitable way the handle 1., of ivory, bone, Wood or other convenient material. The'said metallic body piece to a certain extent affects the shape of a common razor, being fluted at its lateral edges, as indicated at 1", and has a central cavity (as clearly shown in Figs. l and 1), for the purpose of providing a support for the fingers when the razor is being used. The metallic body is enlarged at its end opposite to the handle 25, forming the part 0, conveniently bent as may be clearly seen in Fig. 2, and said part is provided at its conat both sides .and with a milled button (Z' at its center, so as to be able to handle the same with the fingers and fiX'it in position without slipping, Said double comb a is further provided "with two rectangular holes f which register with the pins or similar fasteningjdevices h of the body part c of the razor and serve. to fix the whole of the apparatus in position, in the manner hereinafter pointed out. The fastening devices each have a reduced neck portion, one edge of which is curved upwardly as at h to form a wedge and, at the upper end is an overhanging projection it".

As will be seen on inspecting the section of level between one side and the other of each of the rectangular openings fiso that while on one of the sides the opening is at m at the same level as. the remainder of the comb, at'the opposite there is formed a recess p, shaped like a nail or of other suitable form, the level of which is somewhat lower than that of m. The purpose of-this difference of level will be explained later on. The double combat is also 1 bent or curved like the body part 0 of the razor, as will be seen in Fig. 2, and the button d is placed at its center, on the concave face of thesame.

b is the cutting blade of the razor. which, as previously stated, has two cutting edges and is provided with the holes 9 which also register with the buttons or studsv h, and fit thereon, while allowing of a certain amount of movement of the blade on said studs.

To assemble the parts in position, after all of thedifferent parts bcingthoroughly cleaned, I proceed as follows: The cutting blade 6 is placed into the concave part'of the body piece or frame a of the razor, care being taken toca-use the orifices g to regis- The convexity of the parts az and 0 differs, the former being considerably flatter,

so that both parts, after being simply superposed, will not come into contact with each other, this fact being besides prevented bythe resistance opposed by the cutting blade I). In order to firmly secure allthe partstogether, a slight pressure must be to pressure, to impart thereto a slight movement indirectionftoward the handle. 25 of the safety razor.-This latter will finally assume the position illustrated. at Fig. 4:, being now ready for use.-

In the case shown here, the notch or recess of the-studs it bears on the part m of the openings 7, that is tosay, on the part of higher level, so that the pressure, exerted by the double comb a on the cutting blade 6 l is stronger than if the said notches bore on view shown in Fig. 6, there is a difference the recessed part 3) of the said openings f, and the cutting edge of the blade I) will therefore lay itself snugly on the teeth 0 of the double comb a.

When the comb a is placed over the fastening devices it is forced toward the right, viewing Fig. 1, and the walls of the slots adjacent the depressions are opposite the up wardly curved edges of the necks. WVhen the comb is moved toward the right the walls of the slots adjacent the depressions engage with the curved portions of the necks of the fastening devices, the latter acting as wedges to cause the overhanging portions of the fastening devices to tightly engage the bottom walls of the depressions. In order to vary this pressure, the double comb or is turned on its proper plane so that the part which formerly was up (Figs. 3 and l), will now be. placed down; as for the remainder, the operation of adjusting the parts is the same as before, taking care that when sliding the double comb a, the recessed parts 79 which form one of the edges of its two openings 7", shall remain keyed to the fastening stud' it.

As the different parts which constitute the safety razor, are in snug contact with each other and there are no internal pieces, there is no liability for the soap to get into the interior of the razor when bein operated, so that shaving may be effected much more speedily and with less trouble than with the safety razors as known heretofore.

For dismounting the razor, the proceeding is reversed. Pressure is exerted on the bottom (Z of the metallic comb or, while at the same time a slight sliding movement is imparted thereto in a direction opposed to the handle t of the razor whereby the openings 7 will be released from the studs it, at p or at m, as the case may be, andthe comb, owing to its proper resiliency, will recover its original position, of less convexity than the piece 0 of the razor, or that. which is shown in Fig. 3 of, the annexed drawings. The several parts may then be separated without any 'difliculty, and suitably cleaned in order to beready for the next use.

It will be evident that the construction of this safety razor may be modified and changes. may as well be introduced .as regards the relative dimensions of the parts forming the same and their degree of curvature, without departing from the essential object of this invention of which the main features will be clearlypointed out in the final claim.

Having now particularly described and ascertained the nature of my said invention and the manner in which the same is to be performed, I declare that what I claim is:

In a razor, the combination with a body piece, of a plurality of pins projecting therefrom, each of said pins being provided with an upwardly curving cut out portion and a laterally projecting circular head above the cut out portion, a blade provided with openings corresponding to the pins, a comb member provided with openings corresponding to the pins, the face of the comb member being provided with a depression adjacent each opening to engage the heads of the pins projecting therethrough, whereby lateral movement of the comb -member Will cause the heads on the pins to engage or disengage said depressions, and the end walls of the slots in the comb will engage the upwardly curved cut portions of the fastening devices and act as a wedge and thereby force the bottom walls of the depressions against the underside of the lateral projections when assembling the parts, the comb member having a serrated projection on the outer side thereof by means of which the member may be moved in the proper direction.
