In one and a preferred construction, as shown in Figs. 1 to '7 inclusive, the upper end of the blade supporting and dispensing shaft 2b is provided with a thrust bearing plate 2i, which is suitably aiixed thereto so as to rotate therewith. This thrust bearing plate ZI bears against the under face of the top ywall lI of the casing so as to prevent upward axial movement or displacement of the shaft 2li. The upper end of the blade supporting and dispensing shaft 29 terminates in an axially extending journal portion 22 which is journaled in a bearing opening 23 with which the top wall I I of the casing is provided. Said journal stud portion 22 projects exteriorly from the top wall I I of the casing, and xed upon the projecting end of the journal portion 22 is a manipulatable finger-piece or knob 2t, by means of which the blade supporting and dispensing shaft 2E) can be rotated. The linger-piece or knob 2li bears against the outer surface of the casing top wall II, thus holding the shaft 2D against downward axial movement or displacement from its operative assembled relation to the casing top wall, and therefore maintained in operative assembled disposition within the casing interior.

Means is provided for limiting the direction of rotation of the blade supporting and dispensing shaft 2u to one which will result in downfeeding movement therealong of the blades l5 supported thereby, and in successive discharge of the blades from the lower free end of said shaft. If the screw-thread of the blade supporting and dispensing shaft 2U is a right hand thread (as shown), this means is so arranged as to permit rotation of the shaft in counterclockwise direction, while preventing rotation thereof in the opposite or clockwise direction, An illustrative form of means for so controlling the operative rotative movement of the blade supporting and dispensing shaft 2e, as shown more particularly in Figs. 3, 6 and '7, comprises a detent member 25, which is aiiixed to the upper end portion of the shaft 2i! so as to rotate therewith, and so as to underlie the thrust bearing plate 2 I, detent member 25 is formed to provide a substantially radially extending spring arm 2b which terminates in an upstanding check-nosing 2l. The thrust bearing plate 2l is provided with an opening 28 to permit upward extension of said check-nosing 2l therethrough and into a corresponding opening 29 provided in the casing top wall I I. The opening 29 is formed at one side to provide a perpendicular stop shoulder 35 which is adapted to be normally abutted by said checknosing 2l, so as to stop the blade supporting and dispensing shaft 2@ against movement in clockwise direction. Said opening 29 is formed at its opposite side to provide a downwardly inclined cam portion 3l, which is operative to depress the check-nosing 2 so as to withdraw the latter, against the tension of the spring arm 26 from the opening 29, when said check-nosing is moved in counterclockwise direction, thus permitting rotation of the blade supporting and dispensing shaft 20 in like counterclockwise direction.

The interior of the casing, although of a length substantially corresponding to the lengths of the blades I5, is of a width appreciably in excess of the widths of the blades, so that the blades Said as supported within the casing, and as guided for downward movement therethrough by means presently to be described, will be so disposed relative to the casing side walls I2 that the sharpened cutting edges of the blades will be spaced away from said side walls and prevented from making injurious or dulling contact therewith.

Provided within the internal junctures of the side and end walls I2 and I3 of the casing are vertically disposed or perpendicular guide ribs 32, which are arranged to extend between the top wall I I and the open bottom or mouth of the casing. These guide ribs are of crosssectional shape to respectively correspond to and engage within the respective corner notches le of the blades I5, and laterally opposed guide ribs are spaced apart correspondingly to the widths of the end portions I9 of the blades; all whereby the blades, although free to move bodily downn ward through the interior of the casing, are nevertheless held against undue longitudinal and lateral shifting movements, and also against rotative movement about the axis of the screwthreaded shaft 20 by which the plurality of said blades are supported in a stack or column formation within the casing interior.

The stack or column of blades l5, as suspended by the -blade supporting and dispensing shaft 223 within the casing, is so disposed that its lower end is spaced above the plane of the open bottom or mouth of the casing, thus providing within the open bottom end of said casing a space or socket 33 for the reception of the head H of a safety razor R., whereby the casing can be applied to the razor head so as to oppose the bottom-most blade of the stack or column of blades thereto, subject to discharge of said bottom-most blade, by operative manipulation of the blade supporting and dispensing shaft 2Q, for deposit upon and in assembled relation to the razor head. Within said space or socket 33, the guide ribs 32 are out away or recessed to provide razor head seating shoulders or stops 34, the latter being upwardly offset from the plane of the open end or mouth of the casing.

Before applying the casing to the razor head H, the blade clamp-cap C of the razor is displaced from said head H, whereby the blade receiving top of the latter, together with the blade engaging projections P with which the head is provided, are exposed for reception of a blade I5. When the casing is applied to the razor head H, the ends of the latter will be abutted against the shoulders or stops 35, so that by engagement therewith and as straddled by reduced end portions 35 of the guide ribs 32, which extend below the shoulders or stops 34, the razor head will not only be disposed in a plane adjacently below and parallel to the face plane of the bottom-most blade I5 of the stack or column thereof, but also in longitudinally aligned relation to the latter so as to dispose the blade engaging projections P of the razor head H in aligned relation to the medial slot I6 of said blade.

After the casing has been operatively7 assembled with the razor head H, as above described, the bottom-most blade I5 of the contained stack or column of blades can be discharged and dropped over the blade engaging projections P and onto the razor head H by rotating the fingerpiece or knob 2d in counterclockwise direction one full revolution. Such manipulation of the iingerpiece or knob 2li rotates the thrust bearing plate 2i and detent member 25, so that the checknosing21`ofwthe latter-.rides out of .the opening... 29 of the'casingtop wall Il, and travels. around beneath said top Wall unitil it is again brought intoregistration with and so as to reenter saldi` opening 29,'thus indicating the completion of.. one full revolution of the finger-piece or knob.`

The turning of thenger-piece or knob 24. one

fullrevolution causes.` the blade supportingand l dispensing shaft Z to make a correspondingcfullf.

revolution, whereby the blades l-.ofthezstack or-columnthereof, as engaged by the screw-f thread of the shaft, `and as held against rotative movement by the casing, are all caused to descend along thefshaft a distance corresponding ,tor the pitch of the screw-thread thereof. Such downfeeding movement of the stack or column of blades causes the bottom-most blade to feed offV from the lower free end of the shaft, and thus to be `released from the support of the screw-` thread. When the bottomemost blade 'is thus released, the same drops, by gravity, onto the razor head H and over the blade engaging projections P thereof (see Fig. 5).

After a bladeis thus discharged from the casu ing onto the razor head H,.the` casing is removed from the latter, and'thereupon the bladeclampx-w ing cap C is applied in its operativeblade engaging relation to the razor head. It `will belobviousf that-these operationscan all be performedwithl out necessity for the operator to tonchy a blade at any timaand consequently all risklof cutting the `lingers is positively eliminated. The above described blade dispensing operations maybe repeated until the last blade ofthe stack or column thereof has been discharged and the casing is empty.

Referring to Figs. 8 and 9, there isshown thereby a modified `arrangement for mounting` and actuating the screw-threaded blade supporting and dispensing shaft 2@ of the magazine: In" this modified construction, the external iinger-` piece or knob 24 Ais eliminated, andthe thrust bearing plate is modified so as to serve both as `a journaling support for the shaft 2&3 as well as a" means by which the latter can be actuated. To this end a circular bearing plate 36 of a diam'- eter exceeding the width of the casingispro# vided. Said circular bearingy plate 35 is rotatably supported in bearing openings 3l. with'which" the side walls i2 of the casing are provided,` and. which are. conformable toopposite peripheral portions of said bearing plate. The bearing openings tl underlie the top wall ll of the casing, so` as to support said Abearing plate 35i `contiguous to the inner or under face of said casing `topwall. The blade supporting and dispensing shaft'Zllis suitably aihxed by-its upper end .to said 'bearing` plate 3E, so.as to depend from the latter, and' so as to rotate therewith. Aflixed tothe blade` supporting and dispensing shaft QM `so as to` underlie the bearing plate 35, is the detent mem--` ber 25 having the spring` arm 25 "which termi nates in the check-nosing 2l. Said checklnosing.. 2l projects upwardly through the bearingplate for releasable engagement in theopening 29"of the casing top Wall ll, all in the same manner andforthesame purposes as already setforth.. in connection `with the heretofore first described form of the blade holding and dispensingdevice.A It will be obvious, that by engaging.. opposite exteriorly projecting peripheral portions of `the bearingplate- 35,. rotative movement in proper. direction maybe imparted thereto, wherebyf to.. rotate the blade supporting and dispensing shaft 20 .i forwthe blade discharging Aoperations -above .i

described..

As` shown Uin Fig. 10, removable cover means maybe provided, ifdesired, `for closing the open. Ybottom end or mouth of the magazine casing It. will be understood -thatlvariation in the detail construction and arrangementof ther-parts i ofthe device, and inits blade `holding capacity,
