3 Claims. (Cl. 30-158) particular directed to certain *novel improvements'jin the :design and construction thereof. It .is :among the objects of 'my invention to provide a safety razor comprising a minimum number of parts. u

Another :object is to provide a safety razor which mayibe inexpensively produced.

' A further object fis to provide a safety razor *which ':may 'tbe' rapidly' assembled and disassembled, and which idoes not require disassembly' for removal or replacement of the blade, :or "for cleaningroperations.

An additional 0'bj ect is :to provide a structure of the class' indica'ted, resulting :in economy of 5 .of the safety razor shown in Fig. 2 illustrating its closed or clamped position.

Fig. .5 is a view of the upper portion .of the safetyrazor shown in Fig. 4 but illustrating :the same'i-n open position for removaLor replacement of ,the razorbla'de.

The hollow generally cylindrical handle -10 is externallythreaded at its upper end as indicated at H to receive the collar l2 internally threaded as at l3 of the guard member 94. The guard member 14 may be provided with teeth It extending along its anterior lateral edge and the terminal lugs or projections l6 which serve to alignthe inserted razor blade !1. The pins 18 serve additionally to locate and align the blade I! which may be provided with holes 2t, specially arranged to fit over the pins !3. The guard member i4 is formed in such a manner as to present a rearwardly projecting portion 2! hav ing its lower end provided with the collar 12 internally threaded as hereinbeiore described. I

The member 2|v is also provided with vertical upwardly extending flanges 22. The clamping member 23 may be pivotally attached to the flanges 22 of the guard member M, by means of a threaded pin 24 which passes through oppo- 2 sitely-disposed holes 2-5 .in the router flangesgfi .of th'exclamping member 523 and the correspond- ;ing holes 21 .of the flanges 322 of the guard inember 14. The clamping member =23 may have a length equal to that :of the guard :member 14, and be provided with: downwardly projecting lugs '28, which abut 'the en'ds 29 o'i 'theigu'ardimember I 4, and which 'are in 'alignm'ent with the "terminal lugs 2i 6 in the 7 closed position of thesa'fety razor. The clamping member 23' maybe provided with a downwardly eXtending portion 3" centrally disposed between the outer fianges iii-and defining :anuangularly inclined' raceway or channeI Sl having a aconstricted lower portion "for the purposes to.'be hereinaiterindicated.

The cylindrical handle is internally-threaded as at Z32 to receive :ascrew spindle I33 threaded as at 34. The -screw spindIeBS- terminates upwardly in azstructure adopted.forcomplementary insertion within the raceway or channel 3|. The terminaLp'ortioniof the screw spindle dz-may conveniently ta ke the form ofa ball tip 35, -=as ishown .inhthe drawings; t

Ugpon a-sse'm'bly, the ball-tip 3.5 of the screw spindle 3-3 is retained within the -angularly-in- :clined 'charrnel 31 of the clamping member 23. Pivotal :movement 0f @the "clam-ping member 23 with respect "to the guard member M may be achieved by advancement :ofthe screw spindle '33. This movement 'imay conveniently :be a'coomplish'ed v.by-iro'tatingthe :knurled lower end 31 of the screw-s-pindle iit. -Removalzof .the blade may be efieoted by rotating the iknu'rle'd end 31 of the screw-spindle ifii in 'areverse direction to move the clamping meinber I 23 away from the guard member 4, thereby f-reeingtheblade Pl '1, as illustrated in Fig. 5.

The alternative embodiment of the principle of my invention showing a modification of structure and co-action between the handle 40, the non-threaded spindle 4 I, and the clamping member 23, is illustrated in Fig. 3. This arrangement contemplates the use of a bayonet slot 42 disposed conveniently at the lower end of the handle 40 adapted to engage and retain a bayonet pin 43 projecting from the spindle 4|. In the illustration thereof, as shown in Fig. 3, the razor is in the closed position analogous to that illustrated in Fig. 4 for the previously described embodiment. The razor may be opened so as to separate the clamping and guard members by turning the knurled end 44 of the spindle 4| (which is not threaded as contrasted with the threading 34 of the screw spindle 33) thereby bringing the pin 43 into alignment with the 1. A safety razor comprising a handle having a hollow bore, a guard member having a longitudinally disposed bed for a razor blade and a centrally positioned and rearwardly projecting section adapted to engage said handle, said section having a pair of upwardly disposed and spaced-apart flanges, a blade clamping member having a centrally positioned and rearwardly projecting section, said section of the clamping member having a pair of downwardly disposed and spaced-apart flangesysaid section of the clamping member also having a centrally disposed portion with an arcuately and downwardly extending slot, said slot opening into a second larger slot of substantially circular cross section, .a pin extending through all the aforesaid flanges whereby the guard member and clamping member are held in pivotal connection, a spindle extending within said handle, the upper end of said spindle having a tapered portion carrying a ball, the said ball being held slideably in the aforesaid circular slot and the tapered portion within the first mentioned slot, whereby motion of said spindle serves to move the clamping member, thereby to look a blade positioned be tween said clamping member and the guard member.

2. A safety razor comprising a tubular internally threaded handle, a guard member having a longitudinally disposed bed for a razor blade, and a centrally positioned and rearwardly projecting section adapted to engage said handle, said section having a pair of upwardly disposed and spaced-apart flanges, a blade clamping member having a centrally positioned and rearwardly projecting section, said section of the clamping member having a pair of downwardly disposed and spaced-apart flanges, said section of the clamping member also having a centrally disposed portion with an arcuately and downwardly extending slot, said slot opening into a second larger slot of substantially circular cross section, means for pivotally connecting the pair of flanges of the rearwardly projecting section of the guard member with the pair of flanges of the rearwardly projecting motion of the clamping memher, a spindle threadedly engaged within the internal threads of the handle and extending therethrough, the upper end of said spindle having a tapered portion carrying a ball, the said ball being held slideably in the aforesaid circular slot and the tapered portion within the first-mentioned slot, whereby motion of said spindle serves to move the clamping member thereby to look a blade positioned between said clamping member and guard member.

3. A safety razor comprising an internally threaded tubular handle, a guard member having a longitudinally disposed bed for a razor blade, and a centrally positioned and rearwardly projecting section adapted to engage said handle, said section having a pair of upwardly disposed and spaced-apart flanges, a blade clamping member having a centrally positioned and rearwardly projecting section, said section of the clamping member having a pair of downwardly disposed and spaced-apart flanges, said section of the clamping member also having a centrally disposed portion with an arcuately and downwardly extending slot, said slot communicating with a channel parallel with said slot and of larger transverse cross section than the cross section of said slot, means for pivotally coonnecting the pair of flanges of the rearwardly projecting section of the guard member with the pairs of flanges of the rearwardly projecting section of the clamping member, a spindle threadedly engaged within and extending through said handle, said spindle terminating in a section, of reduced diameter, extending through the aforesaid slot and carrying a terminal tip of larger diameter than the said section, said tip being held in slideable engagement within the aforesaid channel, whereby motion of said spindle serves to move the clamping member thereby to lock a blade positioned between said clamping member and guard member.
