SAFETY RAZOR.

Application led Aug-ust 3, 1927. Serial No. 210,368.

This invention relates to cutlery and more particularly to a razor of the type known safety razors and including a handle, a blade carrier and a guard.

One object of the invention is to provide a safety razor in which the guard is disposed between the handle and blade carrier and includes a roller disposed in advance of the blade carrier and adapted to bear against the cutting cdgeofa blade so that the guard serves not only as means to shield the cutting edge of the `blade but also binds the blade to the carrier.

Another object of the invention is to pivot` ally mount the blade ear'ier and guard so that they inay be swung from a folded position substantially parallel to the handle to an extended position for use and also allow the guard and blade carrier to be moved toward and away from each other and thereby allow a blade to be very easily placed between the guard and carrier or removed.

Another object of the invention is to so form the carrier that a blade may be disposed either against its inner or its outer face and in either position allow a roller forming part of the guard to bear against the cutting edge of the blad and exert pressure to bind the blade to the carrier.

Another object of the invention is to pivotally mount the guard and carrier to swing about a common axis and provide the guard with an extension constituting a crank arm and engaged by a spring carried by the handle so that the guard'and blade carrier will be yieldably held in either a folded or extended position with respect to the handle but prevented from accidentally moving out of a set position. l

Another object of the invention is to perniit the guard and blade carrier to be detached from the handle in order to thoroughly clean them when necessary but prevent danJ ger of thein accidentally becoming detached.

The invention is illustrated in the accompanying drawing, wherein Figure l is a view showing the improved razor in side elevation with the guard and blade holder extended in an operative position and a blade disposed between the carrier and guard;

ylhe improved razor includes a handle consisting of a shank l and hand grip 2, a blade carrier indicated in general bythe numeral il and a guard indicated in general by the numeral Ll. rlhe shank l is formed of metal and has its rear end portion fitted into a slot or pocket 5 formed in the forward end of the hand-hold 2 lwhere it is firmly secured bv a rivet or other suitable fastener 6 which also serves to secure the leaf spring 7. The forward end portion of the shankiis enlarged to provide a head 8, and this enlarged forward end portion of the shank is bent transverselyvv to form a seat or bearing 9 which is open at its rear, as clearly shown in Fig. 6. It should be noted that the forward wall of the bearing extends upwardly to provide a lip 10 which extends rearwardly at an upward incline. The purpose of this lip will be hereinafter clearly set forth.

rlhe guard 4lconsists of a roller 11 and a yoke l2 which is substantially U-shaped and formed from a strand of wire bent to deiine a bridge 13 having arms 14 extending forwardly therefrom and, as shown in Fig. 6, having their forward ends bent inwardly to provide pins l5 to fit into the end portions of the roller and thereby rotatably mount the roller. It will be. obvious that since the yoke is formed of spring wire its arms ll may be sprung apart in order to permit the roller to be engaged with the pins or disconnected therefrom. Intermediate its length the bridge 13 is criinped to provide a rearwardly extending crank arin 16 against which the free forward end portion of the spring 7 bears whenthe bridge is disposed in the seat or bearing 9. Therefore, the yoke will be pivotally mounted in the bearing with the end portions of the bridge projecting` from opposite ends of the bearing and the spring will serve to retain the bridge in the bearing but perniit the yoke to be swung either to a folded position as shown in Fig. 3 or to an extended position for use as shown in Fig. 1. Engagement of the roller with the shank prevents the bridge from being swung inwardly beyond the position show n in Fig. 3 and engagement of the lip l() with the under face of the carrier or a blade between the carrier and yoke prevents the yoke from being swung outwardly beyond the operative position shown in if l. The roller, which is shown in llig. G and is the preferred fornnconsists of a cylindrical body 17 having spiral threads 18 which extend about the body throughout the length thereof. shown in Fig. 7 which inay be substituted for the roller 17 is formed with annular ribs 20 spaced from each other longitudinally of the roller. rlhe roller may be provided with openings in its ends to receive the pins 15 or inay be provided with trunnions 2l and the free end portions of the arins 14- oit' the yoke bent to provide eyes to receive the trunnions. ln Fig. 8, the roller 22 merely consists of a strand of wire coiled about a former, such as a metal rod of the proper diameter, to pro vide convolutions spaced from each other and having it, ends bent 'to forni eyes 23 adapted to receive the pins 15.

The blade carrier il is formed as shown in Fig. (i and` consists of a metal plate Q4 which has one end portion bent upwardly and split to deline an intermediate lip 25 which projerts rearwardlyY and tongues at opposite sides of the lip whi-ib are bent downwardly in an ogee curro lo 'torni bearings 2li to engage the portions ofthe bridge 1?) whieh projffct freni opposite ends of the bearing 9. It should be noted that at their inner ends the tongues 'which forni the bearings 2li are provided with recesses 27 into which the en'd portions ot the bearing S.) are received so that the blade carrier may be swung towards and away troni the shank l and yoke without binding against the walls of the bearing. Vlhis interlocking of the blade carrier and walls of the bearing 9 also serve to prevent the blade carrier troni sliding forwardly out ot proper engag nient with the yoke. A pin 28 projects downwardly froin the plate 2li t pass through an opening formed in a blade 29 of the type used in a Gillette razor and arms or tongues 30 overhang the upper face et' the plate at opposite sides thereof to en- 'lhe roller 19' gage a blade 31 of the type used in a Geni razor. t will be obvious that blades ot' a conventional construction other than those specifically nientioned may also be eingagetlY the blade disposed against the inner face of the carrier with the pin 2S passing through the usual central opening formed in the blade and a sharpened edge portion of the blade projecting forwardly from the Afree forward end of the carrier. The guard lnay now be swung toward the blade carrier or the blade carrier swung toward the guard so that the roller wil bear against the cutting edge of the blade in advance of the carrier. By referring to Figs. 1 and 3, it will be seen that since the guard is acted upon by the spring the roller will apply pressure to the cutting edge of the blade when the guard and carrier are swung outwardly to an extended position and this pressure will canse the blade to be tilted slightly so that its inner portion bears against the lip 10 and .its outer portion will be pressed tight ly against the outer forward edgeof the carrier plate. Therefore, the blade will be tightly bound against the carrier and will be prevented from slipping when the razor is in use. In View of the fact that the ribs of the roller engage the cutting edge of the blade transversely thereof and are preferably spiral, the ribs will create a honing action when the roller rotates and serve to sharpen the blade as well as constituting a guard to prevent the blade from cutting when the razor is in use. After the razor has been used and it is desired to clean the saine, the guard and blade carrier are swung to the folded position shown in Fig. 3 and the carrier can then be inoved to the position shown in Fig. L by pressure applied to the tongue lllhen the carrier is inoved to this position, the blade will be released and will drop out o l? engagement with the carrier. After a thorough cleaning operation has been performed, the blade can be again placed against the inner face of the carrier and the carrier swung to the folded position. When in this position the blade will be retained in place and since the guard and rarrier are disposed substantially parallel to vthe shank 1 the razor will he reduced to a compact niass and may be plzfxred in a slnall package or safely rarried in a pocket without danger. v

it a blade of the type used in a Geni razor is to be en'iployed, this blade, which is indicated by the nurneral 31, is slid between the plate 9A and tongues 30 until the thickened back 32 of the blade is disposed between the tongues and upwardly bent or rolled portion of the plate and the sharpened edge of the blad-e projects forwardly from the carrier, as shown in F ig. 5. By referring to this figure,

it will be seen that the roller will bea against the sharpened edge of the blade 3l similar to the manner in which it bears against the sharpened edge of the blade 29 and will apply pressure which will cause the blade to be pressed tightly against the retaining tongues and in front of the rolled portion of the plate 2l and lirmly bound to the carrier. Therefore, a blade may be applied eitherI against the outer or the inner face of the carrier. lt will also be seen that when the razor is not in use and is folded as shown in Fig. 3 with blade clamped between the carrier and `guar-d a blade 3l to be used as an entra blade may e inserted beneath the` tongues 30 and easily carried without danger of its becoming" detached from the razor.

In Figs. 9 and l0, l have shown a guard to be employed when it is desired to trim the hair at the sides and back of the head. This guard is provided with pockets 31 l at its ends to receive the pins l5 and also has its end faces formed with diametrieallyY extending grooves intended to receive the forward end portions of the arms le and releasably lock the guard after a half turn has been made by the guard. Longitudinally extending re cesses 36 and 37 are formed in the guard at opposite sides thereof with respect to the grooves or seats 35 and the guar-d is also cut to form teeth 38 and 39 disposed in operative relation to the seats 36 and 37. lli/hen this type of guard is in use, the cutting edge of the blade is received in either the seat 36 or the seat 37 and the teeth 38 and 39 will constitute gages to Control the extent to which the hair will be trimmed. It should be noted that the teeth 38 are deeper than the teeth 39. Therefore, when the blade is seated in the recess 3T. the hair may be trimmed closer than when the blade is in the seat Therefore, a person may trim the hair at the sides and back of his head without having this done by a barber.

la ll. there has been shown a modilied forni of handle. 'lhis handle consists of a metal. strip doubled intermediate its length to provide a shank or arm ll() and a temp-anion arm di which taires the plaee of the spring 'T and carries side wings 42 to be grasped between the thumb and first liue'er when the razor in use. rl"he forward end portion of the arm l-lO is enlarged to provide a head i3 eorresponoing to the head 8 and this head bent to define a bearing 44.- similar to the bearing' 9 and lip l5 corresponding to the lip 10. `When this form of handle is employed, the ,Quard and blade carrier are construetet similar to those shown in Fig. 6 and applied to the handle in the same manner.
