ncation.

This invention relates particularly to the form of safety razor farming subject mattei' ot a co-pendlng' application tiled by'me Marcl'1'27th, 1908, Serial No. 423,500 and is in the nature of an improvement thereon.

One ofthe-.objects lof the invention is to provide an improved form ot rctainingmembers` tor the blade, that will ellectually resist bending or breakage of the exposed parts.

Another object of the invention is to provide means for supporting the blade on its under face at one end thereot', separate from the end member of the holder' and also separate from therspring member.

A further object is to provide a spring at the inner part of the`end member of the holder, ywhich will engage the end portion of the blade and press it into the socket at the other en'd ot' the holder.

Another `object et the invention is tol provide an improved form of removable bladc.

ln the accompanying drawings representing embodiments ot my invention` Figure 1l is a longitudinal setion of. the razor. Fig 2 is a plan-view otl the hold'er with the handle removed. Fig. 23 is a longitudinal vertical sectim of the holder. Fig. 4 is a transverse vertical section on the line 1-4 indicated in Fig. Fig. 5 shows the end ot the holder opposite to that .shown in Fig. 4. Fig. 6 is a tragmentary perspective view of theholder member. without the spring or blade.' Fig. 'T shows the spring member,detached;and Fig. S shows the blade.

'lbe holder is shown comprising a substantially trough-shaped member having en d portionsI l2 and 1?). and a curved bottom portion 14, that may be integral therewith. 'lhe portion 14 is providedj with guard portions 15 and 16 on opposite sides, that copera'te with the cutting edges 17 and 18 of a blade 19..

'Ihe end members on their inner faces near thc-top are provided with recesses or sockets,

intr which project the end portions of the l blade, which recesses are preferably closedv at one end, the outer end heilig open in the construction shown. rlhe end member 12 is shown provided with spaced projectionsQO and 21 that are recessed to form sockets 22 and 23. These sockets have one end closed by walls 2 and respectively at their inner ends to materially strengthen the top Wall of the socket and preventits being bent or broken. The other -end 13 has upwardly projecting portions 24- and 25, provided'with sockets 26 and 27, that are also closed at their inner ends by walls 4 and 5 respectively, for the same reasons. -The sockets 26 and 27 are formed deeper than are the sockets 22 and The blade 1.9 has lugs 30 and 31 at one end, and lugs A32 and 33 at the other club-situated at the corners of the blade.

The distance apart of the ends of the lugs 30 and 32, also that of the lugs 31 and 33, is less than the distance'apartof the end walls of the opposed sockets on each side into which the respective lugs enter,- The lugs 32 and 33 are first caused to enter the sockets 26 and 27 with the' blade inclined, then the other end of the blade is swung downward until the lugs 30 and 31 register with the sockets 22 and respectively, whereupon endwise movementof the blade will canse the'latter lugs to enter their sockets. These latter sockets are of such depth as to prevent the lugs at the other end coming ont of their sockets upon the lugs 30 and 31 being moved' in their sockets until they engage their end walls.

i A. spring is provided for causing the described endwise movement of theblade when vthe lugs 30 and 31 are brought to register with their respective sockets. The spring is located between the projections .24 and 25 ot the holder' end 13, and engages the end portion of the blade. A spring 34 is shown, having a cross piece 35 bridging the space 3G at the end of the holder, and suitably secured to the holder as by rivets. The spring is preferably bent outward and upward and engages the end of the blade.

Means are provided for supporting the blade at the spring-engaging end, that are separate from the. socket portions, and separate from the. spring member. The supporting means constitute a part of 'the holder member, and is shown as formed by lugs 37 and 3S on the opposite guard portions 39 and 40. The sockets 2G and 27 extend downward; or, in other words, are cut awa)1 beneath the lower face of the blade lugs and 33. This will permit the bladeto swing on the lugs 37 and 3S with a practicallyfree downward movement, and will greatly facilitate the enti'aiice of these lugs into their sockets 2G and-27 in the insertion of the blade.

The blade isprovided with intermediate projections 41 and 42 at its respective ends, projecting into the spaces 36 and 43 at the ends of the holder, between the said projections 20-21, and 24---25.A These projections serve as holders or thumb pieces, to grasp the blade for the insertion and removal thereof. The ends of the blade are made identical, so that the blade is reversible endwise, and the blade is also re versible, to have either face uppermost in the holder. The spring is shown as engaging either one of recesses (S1 or 44, in the respective projections 41 and 42 the blade, and engaging the end wall of sueh'recess.

rl`he razor is provided with a removable. handle, similar to that set forth in my said application. The handle is shown as coinprising a tube 50, in one end of which slides a sleeve 5.1. Sleeve 51 is slidable on the stern 52, an'd has its lo'wer end secured iu` a collar 53 fast in the tube 50. The stem 52 carries a head 5G havingI transverse arms :'17, and a spring 58 in the tube presses the. sleeve 51- outward, toward the arms 57 of the head. The holder is shown provided with a trans- -verse slot 50, into which the head 5G is inserted with the arms registering with the Slot, the sleeve 51 having been previously pressed away from the' head. ."lien the handle is"turned through 90 degrees, and the sleeve released, when the spring will cause the holder to be clamped between the transverse arms 57 and the end of the sleeve 51. The handle can also be clamped to one end of the holder; the end 12 being shown' provided with a slot G0, at4 which portion the handle can be clamped in the same manner.

ln the act of. inserting the bladepeither end is brought to the holder end 13, and the intermediate projection 41, or 42, is

.caused to enter the, recess 36, and engage the spring 34; and-the lugs 32 Vand 33 directed into the sockets 26 and 27, the blade being inclined, with `the other end raised somewhat. The blade ,is then swung downwardly and at the same time pressed against the spring to tiex it, when the lugs 32 and vwill enter the sockets 26 and 27. This movement is continued until the blade is brought down on the holder, with the intermediate rejection 43 of the blade between the projections 20 and 21 at the end of the holder. The lugs 32 and will enter theirsockets jtirst inserting the end of the blade, its end may be guided into the sockets 2G and 27 b swineiinr on these lues 37 and 38. The

y b t* D 1 otherend of the blade is then brought down onto the holder with its lugs registering. and upon the pressure on the blade, ilexiug thespring being relieved,l the spring will force the blade endwise, causing the lugs 3() and 31v ,to pass into thel sockets 22 and 23 to' engage the end walls thereof. This will shift the lugs 32 and 33 a short distance eutnf'ardly in their sockets, -but not. far enough to be released,- on account ofthe greater depth of such sockets. The operation of removing the blade is substantially the reverse. Pressure is vapplied on the end of the blade at the end 12 of the holder, to tlex the spring and move the lugs at the other end to the bottom of their sockets; which will move the lugs 30 and 31 out of their retaining sockets, permitting the blade :it this end to be elevated; and then the blade is withdrawn from the sockets at the .-pring engaging end. 'llie yblade being identical at. the two ends, it is obvious that either end eau be. inserted first into the, holder.

'lt will thus b e seen that the new form of blade herein set forth comprises a pla-te, 19 of sutlieient rigidity and of proper temper to give the necessary strength to operate practically when lsupported at the end portions only and unsupported therebetween.

iy this improved construction it will be see-n that theoverhanging portions at the. top of the slots 26 and 27. alsol 20 and- 2l. are supported at their inner portions by the side portions of the endmember, that. will prevent' the top wall of the socket being readily bent downward or broken. lt will be further seen that the spring rmember has its tongue 34 located in alinement with the opposite portions of the end member.. and therefore is to a large extent protected therebv/and will not be easily engaged b v an :'"objeet to be bent or broken ln order to 'member 34, according to which end is in- -rsei-ted m this end of the holder. These latter ltltl recesses thereby fgrm an intermediate paii` of lugs that together constitute the grasping portions for the blade. While this intermediate pair of lugs is not necessary for positioning the blade in the holder. nor

do they perform any necessary function to retain the blade in position, it will be seen that they are required to properly manipulate the blade for its insertion and removal. And it will be understood that. these intermediate projections extend beyond the end projections, because the latter terminate in the sockets in the end members,

while the intermediate projections must extrein'ities of the end pair of lugs.

llaving thus described my invention, 'l claim:
