May 16, 1933. J. c. SHERMAN PACKAGE OF RAZOR BLADES Filed March 25, 1930 having a Patented May 16, 1933 JOHN C. SHERMAN, F GOBI-IAM, MAINE PACKAGE 0F RAZOR BLADES I Application filed March 25, 1930. Serial No. 438,804..

'This invention relates to a package of safety razor blades particularly adapted for convenient use with a safety razor such as p is described in my applications Serial No. 251,561, filed February 3, 1928, Serial No. 339,527, filed February 13, 1929, and Serial No. 401,402 filed October 22,1929. The present application is a continuation in part of these copending applications. 7 I I 2 An object ofthe package hereinafter describedisto facilitate the changing of blades in a safety razor withouttouching the blade itself'with'the fingers. Tothis end a pair ofsmall hooks or catches are provided on a'guard plate of the razor itself, the catches being adapted to pass through suitable apertures inthe blade and to catch on the lower face of the blade. For the successful operation of such arazor 1n picking up a blade, it

'20 is necessary 'toprovide a suitable clearance beneath the apertures through which the catches are to extend so that the catches may project throughthe blade far enough to catch on the lower face. .To this end the individual blades are arranged in alternation with a series of spacing elements which are suitably perforated to provide the desired clearances; Accordingtothe invention, a suitable support maybe provided for holding the blades I .30 in conven ent position to be picked up the guard plate of'the' razor. The spacing elements may be made ,of suitable material adapted toenclose andprotect the from the atmosphere.v

135 For a more complete understanding of the invention, reference may be had to the description-thereof whichfollows and to the drawing, of which,,' v

blades Figure 6 is a perspective view of a complete package of blades. 2

Referring to the drawing in detail, the package may consist of a number of blades 10, each blade having a series of three apertures 11 therein which may, if desired, be connected by a slot12, these aperturesfand slots being for the purpose of receiving portions of the razor itself adapted to hold the blade in position. The blades 10 are also provided with apair ofaperture-s13 adapted to receive the catches on the guard plate of a razor such as is described-in my copending applications 'hereinbefore referred to. 'Between each successive provide a spacing element 20 which'may be made of any substance suitable for the .purpose such as wood fiber whichis-cheap" and easily obtainable. Each spacing element is preferably indented on one or both of its 7 faces, as at 21, the maximum thickness of the spacer being inthe form of'a narrow rim -22-which extends around the depressed por tion 21 of the faces.

For convenience in handling a finger tab 23 may be provided at an end of the spacer. c

e In order to provide suitable clearancebeneath the perforations 13' so, as to permit the hooks of the razor: to pass freely through the perforations 13 and to catch on the under 8 side of the blade 1O, suitable perforations 24 may be provided in the spacer 20 I These may be made of sufficient size to include also the two apertures 11' which are adjacent to the perforations 13, so that the entire package may be placed on a pair of supporting pins 25 I which, in turn, may be mounted on asuitable platform 26. The recessed portions 21 pressed into the faces of the-spacer are adapted to be sufliciently deep toreceive a blade between successive spacers and'to permit the outer rims 22 tov rest against'eac'h other, as V shownin Figure 4, thus protecting the'edges of the blade from contact with the spacers and from exposure to the atmosphere. Where both faces of each spacer'are indented,

the depthlof the recesses is preferablyhalf the thickness of a blade,-as s'hownin Figures 3, 4. and 5, so that when the rims 22 of successive spacers-are in face to face contact,

pair ofiblades I may 65:

the indented faces of the spacers abut the faces of the blade between them. This results in the enclosure of the cutting edges of the blades in compartments which are cut off completely from the outside atmosphere. The clearance between the cutting edges of the blades and the spacers may be increased, if desired, by indenting more deeply the portions of the faces of the spacers 27 adjacent to the rims 22, as shown at 27 in Figure 5. This more effectively protects the cuttingedges of the blades from possible contact with individual fibers which might stick out from the surface of the spacer.

A suitable number ofblades 10 with a sufficient number of spacers toenclo'se them separately may be assembled as shown in Figure 6, with aband' 30.0f paper or thelike secured around the package. In order to pre ventjlateral displacement of thespacers upon each otlier'which might result'in exposure of blades to-the atmosphere, and to stiffen packageas a whole, I may provide a pair of. members 31 which have hollow lower end portions to take over theends of the pins 25. These members may be thin metal tubes, as shown are preferably of a length to eX- tend through a package of blades and spacers from top to bottom. The upper en d portions of: these members may bev s ightly enlarged so as to make a tight fit in the uppermost spacer and thus to retain the members in positioni The pins-'25 of th package holder may have reduced upper portions32 with shoulders 33 adapted to be engaged by the liowerends of the tubes 31. Thus the blades and spacers may be conveniently placed on a support by placing a package above the sup port with the lower ends of the tubes 31 restingon the shoulders'33of the supportingpins 25. Downward pressure on the package will 7 cause the blades and spacers to slide from the tubes3l to the pins 25. "The tie element 80 may encircle. the package between the tubes 31, as shown, so that it need not be removed until the package has beenshifted from the tubes 31 to the pins 25. The tubes 31' and tie element 30 are then removed and thrown away, the spacers and blades thereupon being ready to be removed one at a time as desired. V r
