Specification of'Letters Patent.

' rateneedApne, 1912.

Application inea nay 1a, isos. serial No. 326,026.

of New York city, borough 'of Manhattanyf New York, have invented certain new and useful Improvements in Razors, of which the following is a specification. y

One. object of my invention is to provide an improved blade holder whereby the blade may be readily inserted and removed and will be firmly held when in position for use. In carrying ont this part of my invention I provide a blade holder with a pair of jaws to receive a blade between them, and which jaws have means to detachably retain the blade in its holder,.and so arranged as to permit the blade to be applied to and re; moved from the holder bysliding the blade lengthwise, and such holder firmly grips the back part of a thin blade to stiften the same.

I have. shown my improvements as applied in connection with the class of safety razors shown in Patent No; 759,262, issued to me May 10, 1904, wherein means are provided'tin the razor to permit the blade to be rocked back and forth for stropping it.

Another object oi my invention is to provide improved means for movably supporting a guard so that the same may readily be applied to and removed from engagement with the blade, to permit the latter to be held for shaving purposes and to be rocked for stroppinp,- it, and to this end I provide the razor with a guideway that receives an extension from' the guard to support and guide the latter so that it may be vmoved toward and from the'hlade edge,` and a spring co-aets with the guard extension to normally hold the guard in operative posit-ion with respect to the blade.

A further object is to provide improved means for adjusting the guard with respect to the blade edge.

The invention further comprises the novel details of improvement that will be more fully hereinafter set forth and then pointed out in the claims.

3, 3, in Fig. 1, Fig'. It is. a detached face view ofthe blade holder and blade, Fig. 5 is a section on the line 5, 5, in Fig. 4, Fig. 6 is a similar view showing the blade partly de- 'taclied'irom the holder, Fig. 7 is-a perspective view of the guard, Fig. 8 is a detail perspective view of the guideway for the guard, Fig. 9 is a detail perspective view of the blade, Fig. 10 is a plan vie-w .showing the guard provided with means to adjust it with respect to the blade edge, F ig. 11 is an inverted plan view thereof, Fig. y12 is a section on the line 12, 12 in Fig. 10, and Fig. 13 is a `det-ail sectional view enlarged of part of Fig. 12.

Similar numerals of reference indicate y like parts'in the several views.

In the drawings the Al'rame of t-he razor is indicated as having a base portion 1 and upturned vend portions 2, between which end portions a roller 3 is journaled and it carries at one end a gear 4 that meshes with into depressions in thel shaft, at a, or bya,

screw, or inl any other suitable manner.

The jaws 7, 7b of the' blade holder are ar? ranged to firmly grip the blade 8 between them, as by spring action, and said jaws are shown open or unobstructedat one end,

at 9, to permit the blade 8 to be thereina gear 5 secured to the blade holder. In the sertedand pushed lengthwise between 'the jaws, and atvthe opposite end 10 'the space between the jaws is shown `closed by a 'lug or abutment 11 -to limit the passage ofthe blade lengthwise between the jaws. lug may be formed ,by stamping it out `of one jaw, as 7, at one edge and folding it across the space between the jaws andv entering the lug in a recess 7c in the edge of the At the opposite oropen end of the jaws I provide an abutment or stop 12 to engage the blade to prevent detachment of the blade from its holder during use. The stop 12 is shown carried by the jaw 7a and is illustrated in the form of a sleeve mounted upon a bar 13 that is shown formed on the jaw 7 by cutting a slot 14 therein, whereby the stop 12 will-lie in the path of the blade Said i L jaw 7, as clearly shown in Figs. 4, 5 and 6. y

when.. the latter is between the jaws to prevnt the blade from sliding from between the jaws, as shown in Fig. o, unless pushed. To permit the ready insertion of the blade between the jaws and its removal theretrrun withut undue resistance by the stop 12, I havey shown the jaw 7b asy cut away .at one end, at`15, so as to be shorter than the jaw 7?', .providing thereby a space between the stop l. and the adjacent vedge of jaw 7b. This space permits the insertion of the blade lengthwise between the jaws past the stop 12, as illustrated in Fig. 6, and when the blade' is pushed'fully across the jaws it will snapbchind the stop 12 as shown in Fig. 4, and when the blade is pushed lengthwise from the-lett in Fig. it will slide past the stop 12, as shown in Fig.G. The stop 12 is shown loosely journaled upon bar 18"so that it may normally lie in front-of the blandeend, as in Fig. 5, or may be pressed to one side by the blade whenthe latter is inserted or removed, as in Fig. (if The said construction of the stopl 12 causes it to act 'as an anti-friction roll relatively to the bend of the blade. while latter is being inserted and' pushed home between the jaws or withdrawn therefrom'. To retain the blade and prevent' it from -being pulled outwardly or sideways from its holder l'. provide the blade with nete-luis or recesses 8, 8b in its opposite ends or edges which are adapted to engage the stops 11 and 12. Y

My improvements permit a relatively thin and'soniewhat 'flexible blade to be used, if desired, which can bend at the space 15 while being pushed linto 'or lrom its holder, and the back of the blade may rest against the slialt ll, as shown in Fig. 8, to resist the pressure of the guard against the blade when 'i adjusted. for sha-ving, while the holder shown, by4 'firmly' gripping the thus rearwardly abutted lblade at its back part stili"- ens it.

The'guard l have shown is indicated, gene1rally, at 16 and at vits outer corners is shown pushed.

provided with lugs or lipslT that are turned .back in hook-like formto receive and bear against the blade edge near its two ends, whereby to hioldthe blade in shaving position with respect togthe guard. The guard is mounted to, .have movement relatively to the blade edge, and is shown provided with an extension 18 that-extends across, preferably benemli, the Atrame to the side opposite the guard where it is provided with a finger piece or enlargement 19 to be The extension. 18 is shown stamped out of the same piece of metal as the guard and thereby rigid therewith. The extension 18 supports the, guard and permits adjustment thereof, and for this purpose I have shown the extension 18 as' carried in a guideway located between the. hase 1 of the tension 18 if desired. vvbe held within handle 20 in any suitable proper tension of the strop upon roller d` frame and the handle 20. s a convenient means for the purpose Ihave shown head 21 having a depressed portion or guideway 22 in which the extension' 18 of thev provided with lugs 23 having apertures through which screws 211 may' pass for firmly holding the head 21 to the base 1 ot the trame. The head 21 is shown provided with a tubular extension 21a that is secured to -handle 2O by suitable means, andis shown' within said handle (see Fig. 8), and thereby thehandle issecured-to the trarne with guideway between the frame and handle. At 25 is shown a spring located within thel handle 20 and adapted to co-act with ex'- tension 18 of the guard to firmly hold 'the guard pressed toward the blade and .said

spring is' shown bearing against a lug 26' extending downwardly from extension 18 lthrough thebore in the head 21, which lug may be pressed out of vthe metal oit ex- The spring 25 may manner. For convenience of applying and removing 'the spring l have shownthe same provided withv a tubularportion 25B`that is separated or" split'as at 25b and having an outward spring tendency, whereby when the part 25n is pushed into the handle 20 it will be firmly held in posit-ion therein by guard is received7 and said head is shown .the extension 18 adapted to slide in its spring action and may be readily withdrawn 'trom the handle.

'Bv ineansof the roller 3 and gears Ll, `5

the bladeholder with its attached blade'may be rocked back and forth for stropping the edge of' theV blade, and for this purpose l have shownua space, indi/cated at in Fig.l 8, between the loweredge of roller. 8 and- 3, may be passed', and in order to createthe basel 1 of the frame through which a 105 strop, indicated by dotted lines 27 in Fig.

pose l have shown rods 28 extending between and secured to the uprights 2 of the 'trame upon which rods the Arollers' 29 are mounted.`

It lwill be noted that thel rollers 29 are so located relatively `to roller 3 and the edge of theblade that not only is thestrop powerfully pressed against roller 3 to turn it when the strop is held taut, but also that the angle of the surface of the strop relatively to the edge of the blade may be varied at will during strop ing by drawing the strop `more or less taut/Wand thus greater or less ,rietiohw and at greater or less angle may ,be eciire" withl advantagevin sharpening. y

The guard may be arranged te permit its lis adjustmf'nt with respect to a b/lade edge to y l l l inovldef or a. more orless close shave,v and pose iIt'Figs. 10 and 13 wherein part o the material of the guard is shown cut away on opposite sides otl the center, at 1G, providing a flexible connecting piece at 1Gb between the comb-like member ot' the guard and the main support` or member at 1G, which permits said comb-like member to have movement relatively to the other4 inember 16'3 of the guard and with respect to the blade edge that is held near the corners by the lugs or lips 17.

At 30 is a bar slidably mounted upon the guard, preferably on its lower side, and adapted to cause the comb-like member of the guard to move toward and from the blade edge. .l have shown the bar 30 provided with slots 31 receiving .rivets 32 carried'by the comb-like member 16 ot the guard and having heads which support the bar 30 so it may slide lengthwise. The bar Ois shown provided with projections 33 that are adapted to engage the extended portions 17u of the mainsupportv or member ot the guard, which provides a rest for the blade edge, and from which the lugs or lips Y17 project, and said portions 17n of the guard are shown pro-vided with recesses or reentrant parts 34 into which the projections of bar 30 are 4adapted to fit. rangement is such that when bar 30 is slid to one position, as at the left in Fig. 12, so that its projections 33 engage the portions 17a ot' the guard, the comb-like member o;t` the guard will be caused to move away .from the blade edge by reason oit the relative bending ot' thev comb-like member and the extended portions 17a with respect to each other, and when bar 30 moved in the opposite direction, so that its projections 88 enter the recesses 34, the tension will be relieved and the comb-like member of the guard will move nearer to the blade edge, the lirst mentioned position of the guard with respect to the blade edge providing for a relatively coarse shave, and the second mentioned position oi the guard and blade edge providing :For a relatively close shave. lVhile l have shown the comb-like member and the main member 16C as made in a single piece ot material, they could be separate pieces secured together by the connecting piece 16",

In using my improvements the blade is inserted in the holder by pushing the blade past the stop 12 bdtween the jaws 7, 7, as indicated in Fig. 6,' until the notches 8, 8f ofthe blade engage the stops 11 and 12, and then vthe blade is swung down upon the guard, the latter pushed outwardly, as in dotted lines in Fig. 3, thus enabling the lugs1.7 to engage the edge of the blade near each end, and then the linger piece 19 is released, whereupon spring 25 acting upon `extension'lS through lug 26, will draw the the lugs 17 to engage d, while the blade will guard bach to cans the blade ato This ar-y be held firmly in shaving position with respect to the guard. lVhen it is desired to strop the edge of the blade the finger piece 19 will be pushed causing the guard to move `away from 'the blade, the latter is then swung out of the way of the strop, and the latter may be pushed through the .space ai under roller 3 and above rollers 1,9, after which by holding the strop taut and reciprocating the razor back and forth alQng it the blade will be caused to swing or rock correspondingly and dragged behind the frame with its edge against the strop. The strop may then'be withdrawn and the blade adjusted to the guard in manner before .de scribed.

f ily having the `blade holder firmly grip i the back ou thin is stiiened so that it will properly act upon the strop for sharpening its edge and corrects tendency t0 horizontalwarping or" the blade. y

The relation and disposition of the parts as described ensures continuous precision of adjustment between the guard andblade edge notwithstanding wearof the latter.

Changes may be made in the details and arrangements shown and described without departing from the spirit of my invention.
