1 Claim. (Cl. 30-43) My invention relates to a. shaving implement The outer member IG has a pair of oppositely adapted for use as a dry shaver of the motor disposed upwardly extending portions I8, bent driven type. l at their upper ends at substantially right angles Among the objects of my invention are to thereto. and extending integrally inwardly to 5 provide a shaving implement adapted toA give as form a pair of substantially flat top portions 5 close a shave as desired by the user with posi- I9 connected by a U shaped or channel portion tive clipping action and without pulling hair or, 20. A plurality of spaced and substantiallyiparcausing a burning sensation; to create a shavallel slits 2l are formed longitudinally across ing implement having balanced resilient memmost oi each of the top portions I9; said slits 1 0 bers positioned at yboth sides of the driving shaft continuing at the outer edges of the top portions 10 for permitting the inner movable member to I3 to extend downwardly a short distance on move transversely with respect to the stationary each of vertical portions I.

A centrally disposed aperture 23 tially non-clogging, its parts being so arranged is cut in movable member I1 to receivethe end 20 that there are no portions for the retention oi? of shaft I3 with its eccentric Id. clipped hair; to supply a shaving implement Adjacent the top of my casing I0 an aperture having in eiiect a double head with four shav- 24 iS provided hrellgh Which the driving Shaft ing surfaces, its inner movable member having extends to thehead l5. At both sides of said 25 apair of rows of teeth, and such other objects, aperture 26 and spaced therefrom are a pair oi 25 advantages and capabilities as will later more oppositely disposed slots 25 each having a closed fully appear and which are inherently possessed bottom 26 and an open top 21. The slots 25 are by my invention. tapered so that they are larger at their top l While .I have shown in the accompanying portions 2'I than at the bottoms 2t. In each of drawings a preferred embodiment of my invensaid slots is positioned a resilient member 2B of 3o tion, yet I wish lit understood that the same is such size that its bottom end is positioned against susceptible of modification and change without movement in the smaller bottom portion 23. The departing from the spirit of my invention. top end of each resilient member 28 bears against Fig. 1 is a perspective view of my shaving the outer side of movable member I'I.

member I8 and an inner movable member I'I. My shaving implement in use provides four o5 shaving surfaces so as to give the user as close a shave as he desires with positive clipping action as well as greater convenience. my eccentric is farther oil center than heretofore my device has greater speed. My balanced frictionless pressure construction secures con-v stant and uniform operation vwithout pulling. With mly head having an open channel and no closed portions, clogging is impossible.

'I'he outer member I6, on which is positioned inner member I 'Lis held by clamping members 32 above the upper end of casing l0 and leaves a space 39 between the head I5 and casing l0 for the free exit of cut hair.

Having thus described my invention, I claim:

A shaving implement comprising a casing, a stationary member having slits attached to said casing, a movable member having teeth positioned against said stationary member, a driving shaft having an eccentric adapted to contact said movable member so .that upon movement of said shaft the teeth of the movable member operate transversely to the slits in said stationary member. said casing having a pair of slots on opposite sides of said driving shaft, said slots having a narrow closed bottom and tapering upwardly and outwardly to a wider open top, a pair of resilient Imembers positioned in said slots, the bottoms of Because said resilient members held in'fixed position by the narrow bottoms of said slots, the tops of said resilient members contacting the outer side of said movable member and permitted by the tapering portion and the wider open top of the notches to travel with said movable member and apply continuous balanced frictionless pressure on the movable member against the stationaryvmember, said casing having adjacent its upper sides a pair of oppositely disposed slots, a parof nuts tted within said slots, said nuts each having a screw threaded aperture, said casing having on its upper side portions a pair of oppositely disposed notches, a pair of clamping members each having body portions vadapted 'to iit within each of said notches, said body portions each having a screw threaded aperture, said clamping members each having an inturned ilange adapted to engage the stationary member, and screw threaded bolts adapted to pass through the screw threaded apertures of the body portions of the clamping members and the nuts to hold the clamping members, the stationary member, the movable member and the resilient members against accidental displacement and to retain the resilient members in normal pressure exerted position against the movable member.
