SAFETY-RAZOR.

Specification of Letters Patent.

Patented May 9, 1911.

Application mea May 13, 1910. semi Nq. 561,213.

To all whom it may concern:

Be it' known that I, JAMES HARALSON PACE, a citizen of the United States, residing at Hartwell, in the county of Hart and State of Georgia, have invented certain new and useful Improvements in Safety-Razors, of which the following is a specification.

This invention rela-tes to safety razors, and more particularly to safety razors employing a thin,- but rigid and comparatively unyielding, blade.'

An important feat-ure of the invention "consists in the provision of improved means for detachably locking the blade in posit-ion on its holder, whereby it may be applied to and removed from the holder in a very eiiicient manner.

Another feature of the invention consists 1n providing improved means for adjusting the distances of the blade from its guardI a movable part of the razor which has con-V nection with the blade-adjusting means.

With these and other important objects in view, the invention consists in the con` struction and combinations of parts which will be hereinafter more fully described, and claimed.

-In .the drawings: Figure 1 represents a plan View of a safety razor embodying the present invention. Fig. 2 is a view at right angles to Fig. 1, illustrati g certain parts of the razor in section on t eline -x Fig. 1, and other parts in elevatiointhe bladeelevating leaf an'd blade-locking leaf being shown in open positions. Fig. 3 is a plan view of the blade. Fig. 4 is a detail view, illustrating in plan the main portion of the handle, and the guard. Fig. 5 is a detail view illustrating in plan the blade-elevating leaf and its carrier. Fig. 6 is a similar view illustrating an obverse plan view of the' blade-locking leaf and its carrier. Fig. 7 is a transverse section on the line .fn-m, Fig. 2.

The' main handle portion 1 is shown as the comb or guard for the blade. The plate or holder 3 is also formed with an elongated slot 7, having a forward beveled edge 7a. Near the extreme forward end of the holder 3 is a hook 9, and upon opposite sides thereof the central portion of the plate is formed with a'recess or depression 10, the side walls of the depression being herein shown as formed by inner edges of the comb 5. The rearward extremities of theholder in line with the comb parts, are formed Ona downward bevel, 12, and the central portion of the recess at its forward end is formed as an upwardly sloping bevel 14.

A rigid ring 33 is connected with the plate or holder 3, and sliding therein is -a semicylindrical hub 32 having a rearwardly projecting shank 34 provided with a mutilated, preferably left-hand, screw-thread. The shank 34 is arranged to slide in a suitable guide-way on the plate 3. A lug projecting from the inclined endof the hub 32 is perforated to receive a pivot pin-to hingedly connect therewith the plate-elevating leaf 36, the aperture 38 in the lug through which .the pivot pin passes being, as shown in Fig. 2, vertically elongated to permit vertical play of the leaf. The leaf 36 is shown as having oppositely projecting wings 40, a centrally elongated slot 46 which is arranged to register with the slot 7 in the plate 3, and forwardly projecting branches 43. The lower surface of the wings 40 are formed on a bevel Ato cooperate with the bevels 12 of the plate 3, and the lower surfaces ofthe branches 43 are formed on a similar bevel to coperate with the beveled vsurface 14 on opposite sides of the4 lug 9, on said plate 3. y

Arranged immediately below the late 3, and sliding -in a' 4semi-cylindrical formed between said plate and the ring 33, is a hub 16, having a rearwardly projecting space 'has an internal shoulder 66,

shoulder to receive the head shank 27-whose extremity is shown as being provided with a preferably left-hand mutilated thread 28. The shank 27 slides in the 4 handle similarly to lthe shank 34. The forward portion of hub 16 is shown as being forked to embrace a rearwardly extending lugA on the blade-locking 4leaf 18, said lug and forks being pivot-ally connected by a pin, as shown. The locking leaf 18 has an upwardly projecting lug 20, which is formed with -a vrearward hook-shaped or inclined terminal, and the Iforward portion of the lug 2O hasa beveled. or inclined portion 22 to coperat-e with the inclined forward end of the slot 71 in the plate 3, heretofore described.

An internally threaded ferrule 80, having a milled or roughened exterior, as shown, ts over the end of the vhandle shankl 1, and is provided with an internal thread to engage the mutilated thread 28 on the shank 27,v as shown in Fig. 2. The ferrule is retained on the handle shank by a. nut 72, which engages an external thread 2 on. the shank 1, and fitsagainst a shoulder formed upon the interiorof the ferrule 80. The ferrule is preferably provided with an internal thread at its 4eXtreme rear end, which may receive an externally threaded cap-nut, 74, in order to make a neat finish and entirely cover the parts inclosed within said ferrule. W' ith this construction, it will be seen that, when the leaves 36 and 18 are folded against the plate or holder 3 and a razor blade, 50, having therein the perforations 51, is placed upon the holder so that lsaid perforations will pass over the lug 9 of the holder and the 'lug 2O of the leaf 18, upon rotation of the ferrule 30 to the left,' the locking-leaf and its lug will be carried rearwardly to engage the contracted portion of the aperture in the blade entered by said hook, and will lock the blade firmly in vplace on the holder, as shown in Fig. l.

The handle-shank lis provided with a shoulder -58, and a shouldered ferrule 54 is placed thereon, secured in position by the screw 56,heretofore described. A ferrule 52,

which is preferably milled externally, as 50 shown Eig. l1, is rotatably retained between a shoulder on the ring 33 and the forward end of the ferrule 54. The ferrule 52 has an internal thread which meshes with the thread 34 on the shank of the blade-elevating leaf 36, and said ferrule is furthermore provided at its inner end with locking teeth 5 An adjusting and locking ferrule 64 is rotatably mounted upon the handle shank between the ferrules 52 and 30, and is provided at its outer end with teeth shaped to engage the teeth 58 on ythe ferrule 52. The ferrule 64 n n and is also provided with an openingor slot through said of the screw 56. A coil spring 68 surrounds the shank 1, and

,means described,

is held compressed between the ring 6() and' .the shoulder 66 on the ferrule 64, the normal holder 3, to elevate the blade varying distances from said holder; a reverse rotation of the ferrule 52 serves to withdraw the leaf 36, permitting it to descend along `the inelines and the blade to movein closer proximity to its holder. Under the former adjustment, the blade' is positioned for a deepv shave, and under the latter adjustment for a light shave, as will be obvious. In order 4to determine the position of the blade-elevating leaf, the hub 32 may be provided with a series of lines, as indicated at 48, opposite which theletters L, M and D may be placed, to indicate Light 7, Medium and Deep if so desired. In the position that the parts occupy in Fig. l, it will be seen that the teeth of the ferrule 52 are cngaged by the teeth of the locking ferrule 64, which hold the blade in any predetermined position of adjustment. I'n order to release thc ferrule 52 and change the adjustment, it is necessary to rotate the ferrule 30 to the right, which advances the leaf 18y until the inclined endY 22 of the lug 20 engages the inclined forward edge 7 n of the slot 7, which results in forcing the ferrule 30 tothe rear until its internal shoulder contacts with the forward end of ferrule 72, at which point the ferrule 80 will have moved back a suliicient distance to permit rearward movement of the locking ferrule 64. The ferrule 64 is then moved back, compressing the spring` 68 and disengaging the teeth of the ferrule 64 from the teeth 53 of the ferrule 52. After theadjustment has been effected, the ferrule 64 is released and the spring reacts and forces its teeth into locking engagement with the teeth 53, thereby retaining the adjustment of the parts until the ferrule 52 is again rotated.

Preferably, an extension handle 68 is secured to a ring 78, which surrounds the ferrule 64, andhas a beveled shoulder to enga ge .a shoulder 80 on said ferrule. A rivet 73 curing the handle 68 to the ring 78, has its inner end projecting within a longitudinal i groove formed eXteriorly of the ferrule 64. and said ring is retained on the ferrule by an externally milled locking ring 70, which' has internal threads to -engage the external threads upon the rear portion of the ferrule, as shown in F1g. 2. The handle 68 is, by the pivotally connected with its ring 78, and may be moved to position to be grasped by the hand, as an extension a handle, a holder attached to the handle andr "991,533 l j B from the main handle-portion of the razor (see Fig. 2) or may be moved forwardly and folded Hat againstthe razor (see-Fig. 1.).

It will be noted that the blade is rigid, as cont-radistinguished.from those safety razors which employ 'a flexible or bendable blade, and that said blade is providedv with two edges; if desired, however, the blade may have only' a single'edge; 'j

I do not limit myself. to the details' of construction-herein shown and described, which are merely illustrative of the invention, but reserve the right to embody the invention in other forms which fall Within the scope of my claims. 'l
