Fig. 3, the

major steps

23, 23 are to the left of the minor steps 2I, 2|. If the same blade is turned over, so that the reverse side now becomes the obverse side, the

major steps

23, 23 are now to 'the right of the minor steps 2I, I, as in the lower blade same Fig. 3.

The blades are arranged alternately in the stack formation, with the

major steps

23, 23 alternately at the left and alternately at the right. The distance between opposed minor steps 2I, 2| of the blade is substantially equal to the transverse width of central opening I5 of top plate l2 of the container, so that the

slider legs

24, 24 slide in contact with said minor steps 2|, 2 I. It will be apparent that when the

legs

24, 24 are opposite the minor steps 2|, 2| of the lowermost blade 28, Fig. 5, the stack of blades (including the lowermost one 28) will be held securely in the container, by reason of the

aforesaid feet

25, 25 of the slider legs. The length of these feet "25, 25 (Fig. 5) 'is somewhat less than the difference or step between the minor and major steps 2|, 23 (Fig. 3). Hence when the slider 26 is moved so that

legs

24, 24 are now opposite the

major steps

23, 23 of the lowermost blade 28 (but at the same time opposite the minor steps of the blade next above it), the lowermost blade will drop out, but the remainder of the stack will be held secur'ely (by reason of

feet

25, 25 supporting the minor steps of the aforesaid next above blade" which is now the lowermost). The stack ;of blades cannot shift longitudinally nor later ally since the length of the stack of blades is slightly less than the distance between the inside of end walls I 2a.

The longitudinal dimension of central blade opening 22 'is substantially that of the aforesaid central opening I5 of the container I2. Said -'central opening I5 serves a further function in providing limit stops defining the left-and-right -movement of the slider.

" [One of the functions of the aforesaid pair of end openings I4, I 4 in container plate I2 is to provide guideways for the slider 26. For this purpose, all four corners of the slider plate 29 are recessed, as indicated at 21 in Figs. 1 and 2 (also Fig, 6). It will be noted that the transverse width of arched slider plate 29- is slightly greater than that of the end openings I4, I4; but that the central portion provided in the end edges of a plate 29, by the said corner recesses 21, fits snugly within said end openings, I4, I4 of the container.

The slider 26 is fabricated from 'springy material, such as spring brass or the like. One of the "reasons for imparting the aforementioned arched formation to slider 26 is to utilize the springiness of the metalfrom which fabricated for retaining the slider and the stack of blades securely within the housing (as shown'in Fig. 5). Another rea-- son for imparting the arched formation to the slideris to provide sufficient raised surface or protuberance to permit the slider to be readily movedby the fingers.

Except for the already described central opening 22, the blade 20, Fig. 3 is conventional and has the usual cut-outs, including the central longitudinal slot I9, Fig. 3, in which is received the "central raised ridge (designated 9 in Fig. l) of 'the' conventional safety razor.

I shown in Fig. 1 is of the type which, by a 'twist of a portion of its handle, two side plates The safety razor (2, 2) swing open to expose the blade platform 3 and the aforesaid central ridge (9) uprising therefrom.

The'improved blade dispenser is positioned, in

three square openings I4, I5 and Id of the containing plate I2.

Additionally, the end edges B, B, of the slider are provided with central disposed

slots

39, 39,

d which are sufliciently wide to receive the longitudinal razor ridge 9, so that, at least, the end portions ofrazor ridge 9 will clear therein.

The top plate I2 of container II may have a pair of upstanding arched flanges I1, I! extending longitudinally one on each side of slider 26 to, improve the appearance by concealing the open spaces underlying the arched slider 26. Flanges I1, I! aid in protecting the slider 25 against accidental displacement or movement.

I claim:

A housing for razor blades, said blades having stepped openings, said blades stacked within said housing alternately in reverse position, said housing having a top with an opening, resilient means overlying said top, said resilient means having means for holding a stack of blades within said housing against said top, said blade holding means passing through said top opening in said housing and said stepped openings in said blades to hold the lowermost blade within said housing whereby by moving saidresilient means horizontally right and left said'blades will be released singly.
