SAFETY-IRAZOR.

Specification of Letters Patent.

Patented Mar. 1, 1921.

Application filed April 24, 1918. Serial No. 230,583.

To all whom it may concern.

Be it known that I, J AMES LEO LEAHY, a citizen of the United States, residing at 210 Swan street, Providence, in the county of Providence and State of Rhode Island, have invented new and useful Improvements in Safety-Razors.

My invention relates to improvements in the clamping device of the razor-blade for shaving adjustment and for cleaning the blade without its removal from the holder during the shaving operation and'the ob jects of my invention are first, to hold the blade securely, second, to afford facil1- ties for proper adjustment of the safetyteeth so that blade may be cleaned without its removal and third, to combine mechanism for retaining blade in holder for continuous use until blade outlives usefulness as such.

in many forms of safety-razors previ ously devised, the shaving blade is set in the holder in a flat position, causing the operator to hold the razor in an awkward position in order to bring about the best shaving results from the cutting edge of the blade and in missing the exact position for holding same, the effect of the keenness of the blades edge is usually lost. In other forms of safety-razors it is necessary to remove the easily rustable blade from the holder after each shaving operation in order to clean the safety-teeth or clean or wipe the blade-edge. This involves much time, considerable work and entails the danger of injuring the edge of the blade, or of cutting the operator or material wlth which the blade is wiped.

The object of my invention is to provide a position of the blade to produce the great est effect with the keenness of the shaving edge of the blade and this with the least effort on the part of the operator. It also provides a safety-plate and handle for permanently rasping and clamping a port on of the blac e, the same being provided with mechanism which may be moved temporarily in a position to guard the edge of the blade for shaving, thereby rendering it a safety-razor and at the same time being also adapted to be moved to another positlon in which it is entirely out of the way of the edge of the blade, whereby said blade may be wiped or dried and the safety-teeth may be more easily and quickly cleaned and to this end my invention consists of certain novel and peculiar features of construction and organization as hereinafter described and claimed.

My invention consists in mechanism capabio of accomplishing the position of the flexible razor-blade for the best shaving results, also more in detail, in a permanent safety-plate and holder, equipped with hinged members that can be swung to a position where they guard the blade edge and can be moved to another position whereby they clear the blade-edge. With these old JBCtS in view, I have provided a structure that is simple, novel and economical in construction and that satisfactorily overcomes the objectionable features in prior art.

I attain these ob ects by the mechanism illustrated in the accompanying drawing, in which,--

Figure 1 shows a front view of the back or holder of the razor, made of a concaved piece of metal upon which are soldered one screw-threaded post directly in the center, for screwing the handle on back and holdmg safety-plate in position against razorblade for shaving and two square metal posts equally apart from the center post and near side of back for holding razorblade in place.

Fig. 2 is a side-view of the back or holder 3 mentioned above showing size and posit tion of the screw-threaded center post 1 and the twosmall square posts 2.

Fig. 3 is a plan view of the razor-blade 4: for use in the device of my invention which has one large round hole 5 to allow the passage of the threaded post 1 in back 3 and also two slots 6 to allow the passage of the two square posts 2 in back 3.

Fig. 4- is a plan view of the part of the razor embodying my invention, consisting of a center-plate 9 for assisting in holding razor-blade in place, safety-teeth 7 for protection from cutting during shaving operation, same being swinging members kept in position and swinging from center-plate 9 by means of four small metal pins 8, forced, first through holes'on side of safety-plate 7 then through hole in lug 14 on center-plate 9 and then through hole on safety-plate 7. The center-plate 9 has one large round hole 11 to allow passage of threaded post 1 on back 3 and two small square holes 10 to allow passage of the two small square posts 2 on back 3.. 7

Fig. 5 is a side view of the center-plate 9 in position when safety-teeth 7 are released tor cleaning safety-teeth 7' or wiping blade 4;.

' Fig. 6 is a side view of the center-plate 9 in position for holding blade 41- in concaved position for best shaving results and also showing safety-teeth 7 in place for protection from cutting during shaving operation.

Fig. 7 is a lengthway side view of the swinging members or safety-teeth 7, showing heel for clamping purposes on blade land outline of same for swinging on centerplate 9.

Fig. 8 is a sectional side-view of the swinging members or safety-teeth 7 showing depth of heel 12, for clamping of blade at, position of safety-teeth and hole 13, for forcing pins 8 to giveswinging and clamping properties to swinging members 7.

Fig.9 isa side elevation of the entire safety-razor showing the safety-teeth 7 released and out of the way, so that blade 1- may be wiped, safety-teeth 7 cleaned or position of holder to start removal of blade 4-.

Fig. 10 is a plan View of the entire safetyrazor in position for use in shaving, showing thev safety-teeth 7 in position as such,

the heel 12 forcing blade 4 inconcaved position for best shaving results. In this view is shown the handle 15 of one piece or" steel or other suitable material, shaped atthe top to force center-plate 9 against blade 4 to proper position, drilled to suitable depth and threaded so that when it is attached to threaded post 1 on back 3 it iorcescenterplate 9 and blade 4 in proper position. This handle 15,'is knurled so that it may be operated freely on threaded post 1. The position of the entire safety-razor as shown in Fig. 10 may be brought into position of the entire safety-razor as shown in Fig. 9 by simply forcing safety-teeth 7 toward handle,15 and this may be, accomplished by holding razor in one hand by handle 15 and grasping side of safety-teeth 7 near pins 8 with thumbandindex finger of the other hand. 1 The drawing ingeneral vdisclose economy of organizatiom-irom the fact that but nine pieces of material are used and is also novel in design since it eliminates the number, of parts by combining the features in fewer parts.

In the operation oiithe device, assuming that there is no blade in the holder, the op erator unscrews the handle 15 from the back 3 and removes the clamping member or safety-plate 9. He new places the blade 1 in position on back or holder 3 allowing the threaded post 1 to, pass through hole 5 in center of the-blade 4L andthe two square posts 2 on back 3 to pass through slots 6 on blade 4. He now places clamping members 7 and cordet-plate 9 over blade t so that the two square posts 2 on back 3 pass through thetwosqnare holes -10 on center-plate 9 and the threaded post 1 on back 3 passes through center hole 11. Last, the operator places the handle 15 on the threaded post 1 and re ."olves said. handle until it is at the proper distance -from the back 3; he now brings satiety-teeth 7 in position for shaving as illustrated in Fig. 10. i i hen the shaving operation has been ronipleted. the operator takes hold of the side of the safetyteeth 7 and releases them as a hove described. wipes cutting edge of blade and puts razor away for future use without removing the blade from the holder. When the blade becomes dull or another is desired, the opera tor reverses the operation just described.

Having thus described my invention what l'claim as new and desire to secure by Letters Patent oi the United Etatcs is,-

l. A safety-razor holding device comprising a permanent holder, means for securing the safety-razor blade thereon, movable members pivoted to the main support adjacent to the normal position for the edge of the blade. a handle attached to said permanent holding device, movable members, adapted to he moved to two dil'l'erent positions, in one position holding said movable members in such a position that it will guard the edge of the blade and in the other position permitting the blade edge on the holder to be wiped.
