` This invention relates to safet razorsof.

the tyie in which' a thin flexible b ade is tione for shaving purposes in a holder aving relatively movable clamping members. It 5 is desirable for' the convenience of the user that in assembling the razor for shaving and in disassemblingl it-for cleaning purposes after shaving the blade clamping parts should be tlickly and reliably moved to and from the lade clamping position. Further, that in the open position of the holder the blade may be conveniently presented for removal or replacement without danger of cutting the user or of being improperly positioned in the clamping operation.

In one aspect the present invention consists in a holder having blade clamping parts arranged for movement toward and from each other, and also transversely withn respect to 2 each other, so that when 'the blade clamping pressure is released one of the blade clamping Barts may be moved completely to expose the lade. With the clamping parts so disposed' the user may remove or replace the' blade conveniently and without loss of time. AMoreover, by constructing the parts so that their clamplng movement is properly controlled, the correct position and edge e osure of the blade are insured for the shaving operation.

As herein shown, I secure'the desired re-y sults by providing both the guard and the cap members of the holder with handle portions which are so related and connected as to insure the desiredmovement of the parts. The handle part of one member is guided for longitudinal movement within the handle part of the other member and means are rovided whereby a transverse movement o the two members ispermitted when they have an arm or lever having a toggle connection with the handle part ofthe ard member and so designed that the inal c amping movement of the cap and guard is effected byv powerful to gle action insuring firm engage- 5.1

ment of the lade under adequate pressure to holdthe same andV if desired to impart to it a pronounced transverse curvature. This mechanism as herein shown is also utilized to control the transverse movement of the on cap and guard so that by single movement of the operating device the cap and guard are rst separated and then transversely vdisplaced in opening the razor, or first positioned in an alignment and thenmoved into clamping engagement in closing the razor preparatory to shaving. Y Y

These and other features of the invention will best be understood and appreciated from the following description of a preferred emthe line 3 3 of Fig. 2.

Fig. 4 is a view of the razor in longitudinal 80 section on line 4-4 in Fig. 5, showing the razor in opened condition.

Fig. 5 is a view of ther razor in longitudinal section on line 5-5 in Fig. 1. I'

Fig. 6 is a fragmentary view, partly in sec- 85` tion, showing the parts of the razor 1n an in' termediate position, and

Fi 7 is a plan view of the razor in open condition. v

The razor herein shown comprises a' cap 90 member 10, shown having a concave vblade shaping face, and a guard member 12, shown having parallel fulcrum shoulders over tially rectangular in internal contour. The cap 1s shown provided at each corner wlth a reinforcing lug 18 and with a pair of aligtned blade locatlng ribs 16 which are spaced om each other. as shown in Fig. 5. Between these ribs the cap is provided -with a recess 9 designed to receive with appreciable clearancedtheblade-positioning `rib 13,., of the ar guThe ard member 12 is shown detachably secure to the upper end of its handle part which comprises' a rectangular stem or bar 24 of the proper shape and dimensionsV to slide within the channel of the handle part 22 and be guided telescopically thereby. The

guard member is provided with a central longitudinal groove 11 to receive the ribs 16 of the cap and with a centrally disposed projecting rib 13 shaped to fit the central aperture of the blade 14. l

It will be understood that the handle part 22 of the cap and the stem 24 of the guard are assembled 1n telescopic relation, the stem sliding longitudinally within the channel of the handle and being guided thereby s o that the guard 12 may be moved to free the capA l() in a direction substantially normal to its curved blade shaping face.

Means will now be described for controlling the relative movement of the two rincipal razor parts above described. A nger lever or member 28'is pivotally mounted in the lower end of the handle part 22 to swing about a transverse pin 26 which extends between the opposite walls thereof. The handle 22 is notched .'in its face at 22 to receive the finger lever 28 when the lever occupiesa vertical position as shown in Figs. 1 and 2, in which position its outer surface is iiush with the surface of the handle. The handle 22 is provided also at its lower end with al flange which substantially closes the bottom end ot the channel in the handle when the finger lever is in its closed position. The finger lever is pivotally connected at an intermediate point to the stem 24 by means'of a link 30 and acts through this link to operate the stem 24. Link 30 is shown pivotally connected at 30 and 30 with the stem 24 and lever 28. It will be observed from inspection of Figs. 4

` and 6 that the link '30 and the lower or inner portion of the finger lever 28 act as a toggle in operating the stem 24. The toggle is straightened by the lever action of the finger lever 28 so that a powerful clamping action between the cap and guard is secured with slight effort on the part of the user when the lever28 is swung against the handle part 22.

The longitudinal or vertical movement of the guard member has been discussed hitherto. This is utilized in effecting the preliminary separating movement between the cap and the guard and theirl nal movement into clamping engagement with the blade. As herein shown, however, the

guard member is arranged to, swing transversely out from beneath the cap-after it has been separated from the latter by a predetermined amount. To this lend the stem 24 is provided with the transverse guide pin 32 which is located at a point somewhat above the bottom of the stem. The guide pin 32 extends beyond the stem on both sides and slides in vertical slots or grooves 23 formed in opposite sides of the channel walls of the handle 22. The path of movement of the pin 32 in that portion ofthe channel is consequently positively controlled at all times. When the stem 24 is elevated in the handle 22 its inner face bears against the rear wall of the channel of the handle both above and below the guide pin 32 and under thesecircumstances no transverse movement of the stem is possi-l ble at either end. The rear wall of the channel member is provided near its lower end with a recess 21 which will ermit that portion of the ,stem 24 below t e guide pin 32 to enter it when the stem is lowered into regis-v tration with it as shown in Figs. 4 and 6. The link 30 is provided with a notch or recess to receive the guide pin 32 when the Vfinger lever is swung into its upright position, as best shown in Fig. 2. v

The operation of the razor construction ab'ove described will be apparent but for convenience may be summarized as follows.

the stem 24 is moved out of the recess 21 so that the stem is now free to move vertically. The parts are shown in this position in Fig.

y22 in vertical alignment with and beneath the l cap 10. In' this movement the lower end of 6. Continued movement of the finger lever 28 in the same direction thereupon is eifective bodily to elevate the stem 24,and the guard, carrying the guide pin 32 upwardly in the slots 23 and clamping the blade 14 between the guard and the cap. In this movement the ribs 16 of the cap enter the groove 11 in the face of the guard and the rib 13 enters the recess 9 in the cap and thus the two members are positively centered with respect to each other and are retained from transverse movement relatively one to the other.

After the shaving operation, or when the user wishes to replace a blade, the sequence of operation above set forth is reversed. In the initial outward movement of the finger lever 28 the stem 24 is moved vertically downward until the blade is entirely separated from the capV and until the end ofthe stem 24 is brought into lregistration with recess 21. Thereupon the further final movement of the finger lever swings the stem 21 and the guard outwardly carrying the blade into the exposed position, the inner lower end of the steam 24 engaging the handle part 22, and limiting the outward movement of the guard member, as illustrated in Fig. 7 x

The screw-threaded connection of the 12 with its stem 24 aEords provision for adjustment so that when the finger lever is moved fully to its closed position' as shown in Figs. 1 and 2 theproper degree of clamping blade pressure is-exerted bythe cap and guard. Havingthus described my invention, what I claim as new and desire to secure by Letters Patent is,-
