Specification of Letters Patent.
Application filed February 19. 1912.
. )at ent-ed 'Nm'. 'l 8, 't tlit. Serial Nb. 749.362.
To all 'tolto/m, t may camera it known that I, Daunen Burnin, a citizeuof the United States, and resident. ol
Newport. in the county of Newport and State oi. Rhode Island, have invented certain new and useit'ul lrnprtnf'einents iu Safety* Razors, of which the following is a specifica.- t-ion.
This invention relates to safety razors, the preferred embodiment thereof beituil illustrated by the accompanying drawings.
Figure l' represents a side elevation of the razor in one o't' its operative positions. Fig. 2 represents an elevation o't the opposite side oit' the razor in the same position. Fig. Il represents a perspective View of the blade, the lower end of the shank being broken away.i Fig. 4 represents the satety guard, the guard portion thereof being shown in longitudinal section and the shank thereof being shown in elevation. Fig. 5 represents a longitudinal section, on a larger scale, ot' interlocking portions of the blade and guard, the interlocking portions ot the blade shank and guard shank being shown in elevation, and the intermediate portions being broken away. (See line 5-5 of Fig. l.) Fig. 6 represents a View similar to Fig. 5, showing the blade and guard adjusted to a dill'erent position whereby a. greater space is left between the blade and guard. Fig'. T repre sentis a cross section in the plane indicated by line 7-7 of F ig. 2, showing the blade and guard in the relation corresponding to the adjustment shown by Fig. Fig. S represents a cross section similar to Fig. 7 but showing the blade and guard in the relation corresponding to the adjustment shown by Fig. 6. Fig. 9 represents a cross section in the plane indicated by line 9---9 ot' Fig. 2.
The same. reference characters indicate the same parts wherever they occur.
The blade comprises a longitudinal central body portion l() and two oppositely dis posed cutting edges l1, 1l. The blade provided with a shank 12 whereby' the blade may be attached to a handle 13. As shown by Figs. l and 2 the shank and handle are connected by a pivot; llt in such manner that the yblade may swing into and out of the handle as in the case of an ordinary single-- edge razor. l/Vhen the blade is without. a guard it maybe honed and stropped in the usual manner, as in the case of the ordinary old-fashioned razor, the body portion ltllben ing` relatively thick'. as shown by Figs. 7 and 8, to engage the hone or strop to determine the desired bevel or angle given to the cutting edges and also to stillen the blade.
'the blade has` suitable provisions whereby a guard may be attached. its shown by lt`ig. il. the guard comprises a longitudinal central body portion l5, guard fingers or projections ,16, and a shank 1T. The lingers or projections 1G are disposed in two series oppositely disposed so as to cooperate respectively with the two cutting edges oli the blade in the well-known manner. The toe ot the blade is provided with a notch A1S (see Figs. il and :tor the receptit'in ot a'hook lfl of the guard. The hook is inserted in the notch by inoring the guard Ytrom the toe toward the heelo't" the blade. lhe inner surface 2t) ol the hook is inclined. and the cooperative surface Ql o li the blade is likewise inclined so that the, confronting surfaces of the -guard and blade will be. drawn toward each other as the guard is moved toward the heel ot the blade. ,l'he shank ol.E the guard is provided with ahead which comprises ears 9*? and a neck or web Qhthe ears extent'ling;` laterally in opposite directions :trom the neck, and the neck connecting the ears with the shank.
The shank ot' the blade is provided with a keyhole. slot for the reception of the head ot the guard. The enlarged portion 2t ol` this keyhole slot is large enough to enable the head to passthrough. after which the neck Q3 oit the guard is adapted to traverse the narrow elongatetl portion ot the keyhole slot. The blade shank l is provided with notches QG adapted to receive the ears QQ, said notches being disposed between the ends ot the eltlngated portion of the keyhole slot.
The (poration ol assembling the guard and blade is as `follows:M'lhe head at the lower end ol the guard shank is first passed through the portion 2lY o't` the keyhole slot. 'lhe guard is then 'tree to slide toward the. pivot tt, and when so moved the neck 25? enters the elongated portion Q5 of the slot.
During this Inoveinent the point. of the hook itt) at the outer end ot the guard is inserted in the notch i" the blade. 'When the ears ol the guard head register with the notches 20 in the blade shank, the ears snap into these notches`as shown by Fig. 5 and" the guardand blade are thus completely assembled, the confronting 'faces `olf the guard and blfade being drawn together durl angle to each other. This bend is preferably located at the junction of the shank and body portion. lVhen the head of the guard is ullyinserted into the enlargement of the keyhole slot, the shank 17 lies in contact with the Hat surface of the blade shank 12. and the bend 27 causes the body portion of the guard to diverge with relation to the body portion of the blade. lt is therefore necessary to spring the free end ot the guard toward the blade in order to insert the hook 19 into the notch 18. When the guard is so Sprung, its body portion becomes curved, as indicated by ldotted line 15. The normal angular relation of the body portion 15 and shank 17 causes the ears 22 to spring/into the notches 26 and also causes t-he body portion of the guard to stand away from the body portion of the blade as shown by Fig. 7, thus leaving a clear space 28 between the two body portions. This space 28 is desirable because it enables the lather to pass through, so that the lather will not all col lect upon the operative edge ot the blade. Thisfspace also facilitates the removal of the lather, because water may be freely cir culated between the blade and guard either by immersion or by holding the razor under a running stream.,
The guard is adjustable toward and from the cutting edges and its adjustment is etfected by relative longitudinal movement of the blade and guard. For example, Figs. 1,2 and 5 show the guard in such position that the ears 22 occupy the notches 26, and show the hook 19 inserted into the notch 18 as far as it will go. In this position the space 28 between the guard and blade is rel-l atively narrow. lf it be desired, to increase the space 28 as shown by Fig. 8, so as to shave more closely, the desired adjustment is obtained by springing the guard shank 17 so as to remove the ears 22 from the notches 2G and by then moving the guard slightly toward the toe of the blade, provided it is not moved so far as to entirely withdraw the hook 19 from the notch 18.
Fig. G shows an intermediate adjustment ot the guard. As the guard is moved toward the toe of the blade, the body portion l15 vsjnings laterally away from the blade as far as the inclined surfaces 20 and 21 will permit, and it is duc to the inclination of these surfaces and to the longitudinal relative movement of the guard yand blade that the space 28 between the guard and blade ing and adjusting the guard, and as the h and is at such time at a safe distance troni.
the cutting edges, and as the reaction upon the hand tends to move the hand away from the cutting edges., there is no possibility o the hand coming. in contact with thecutt'ing edges. rlhe friction of the shank 17 upon the shank 12, due to the springiness of the guard, is suiiicient to hold the guard at any desired intermediate position. The handle '1.3 is similar to the handle of an ordinary old-fashioned razor, having two side pieces, as shown by Fig. 2, suitably spaced toreceive between them the blade and attached guard.
It is obvious that the blade may be turned to'any desired angle relatively to the handle and that the razor may be used in exactly the same way as an ordinary old-fashioned.
razor, but that in addition to such use it is.
capable of cutting -in opposite directions, provided the blade is rocked upon its body portion when the direction of cutting movement is reversed. Such rocking of the blade does not necessitate any other change in the may be varied. The unlocking of the Shanks position of the razor relatively to the hand. u
I claim:
