4 Claims. l This4 invention relates generally to magazines and more particularly to magazines having a plurality of razor blades from which individual blades are consecutively feedable.

Among the objects of the present invention lies the provision of razor blade magazine construction which" is adapted for use with razors of known construction and requiring no change in insuchrazors.

Another objectherein lies in the provision of razor blade magazine constructions wherein the blades are arranged in stack relationship so that the cutting edges thereof are prevented from contacting each other.

Another object herein lies in the provision of razor blade magazines in which the stacked blades are substantially protected against outside contamination.

A further object herein lies in the provision of razor blade magazines which are simple in construction so that they may be manufactured inlarge quantities at low cost,V whereby the magazine may be relled if desired, but may be discarded after the contents thereof have been consumed.

Another objectherein lies in the provision of structure of the class described wherein the cutting edges of the blade are prevented from undesirably contacting the inside surfaces of the magazine.

Another object hereinlies in the provision of structure, by the use of which, it is not necessary to touch the blade which is to be removed from the razor, or the new blade nwhich is to be loaded therein.

These objects and other incidental ends and advantages will more fully appear in the progress of thisfdisclosure and be pointed out in the ap pended claims.

Turning now toj` the first embodiment of thev invention illustrated in Figures l to 6, inclusive, themagazine is generally indicated by reference character l). The magazine comprises generally, a easing. Il. a'steeli l2. 0f. razor blades I3. longitudinal Rushing. means I4. e rel-2er e011- neeiing element I5.. blade guiding means I6 and an ejectorfl'l. V

The blades i3. are 0f unie ferrn. eonetruetion. and eeeh'irleludee a bedr 2.5., a cutting edge 26y and a head'Z'l. The head may be provided with a reenforcement, Liz-,shaped in Section. in a Well` knewn menrlef- The blades are stackedy with the cutting edges 2E uppermost spaced from the lower surface of the top wall I9, while the heads 21 rest upon the upper surface of` the bottom wall i8. The rear wall forms a support for the rear end oi the longitu- .A dinal pushing meansl, but otherwise mayhave generally from the plane 6:-.6 onA 3 any desired configuration, serving as it does, to connect the rear edges of the top and bottom walls.

The right side wall 2| is provided with an orifice 28 (see Figure 5). through which the finger 29 of the ejector I1 may be reciprocated.

The guiding means I6 includes a pair of oppositely disposed longitudinally arranged

ribs

30 and 3| which are adapted to coact with correspondingly positioned

indentations

32 and 33 in the blade bodies 25. These

indentations

32 and 33 may be the well-known indentations on blades of this character, which, when in the razor 9 are used to urge the blade into engagement with the appropriate portions of the guard. The rib 30 may be integral with and extended inwardly from the inner surface of the wall 2|. The rib 3| may be integral with and extended inwardly from the extension 34 which may be a false wall supported inwardly of the inner surface of the left side wall 22.Y The extension 34 may connect the upper and lower walls I9 and I8 respectively, and the wall portion 35 may act as a guide for a blade during its ejection as will more fully appear. 'Ihe inner surfaces of the wall 2| and the extension 34 are parallel and are spaced a distance substantially equal to or greater than the total length of each of the blades I3. As will be apparent from a perusal of Figure 3, the portion of the wall 22 rearwardly of the guide 35 and the portion of the rear Wall 20 outwardly of the extension 34 may be eliminated, since this eliminated portion merely furnishes a structural and visual symmetry. The rib 3U preferably extends forwardly from ther rear wall 20 to abut at its forward end against the rear surface of the shoulder 36 disposed on the rear surface along the right Vertical edge of the front wall 23. The rib 3| preferably extends from the rear wall 20 forwardly to terminate coterminously with the forward surface of the wall portion or guide 35. The bottom wall I8 has the forward edge 31 thereof spaced rearwardly from the inner surface 38 of the frontwall 23, a distance substantially equa1 to or slightly greater than the thickness, of a head 21 of a blade I3. The inner surface 39 of the left side wall 22 is spaced from the innerY surface 40 of the shoulder 36, a distance substantiallyV equal to or slightly greater than the length of a blade I3 or the head thereof 21 which is of the same length. The edge 31, the inner surface 38 of the front wall 23, and the inner surface 39, and the inner surface 4U form the margin of the discharge opening 4I through which the blades are consecutively ejected.

Located at the rear of the bottom wall I8 and the lower portion 42 of the rear wall 20 is a stationary spring seat 43 which may have a pin engaging the rear convolutions of the spring 4I. Disposed forwardly of the front end of the spring I4 is a pressure member 44. The member 44 may have a pin at the rear portion thereof adapted to engage within the forwardmost convolutions of the spring I4 and may have a front plate 45 disposed at an angle to correspond with the angle of the shoulder 36. The width of the plate 45 is preferably substantially equal to the width of the shoulder 36.

The front wall 23 is detachably engageable with the forward edges of the side walls 2| and 22. As shown in Figure 3 the front wall 23 has a pair of tongues 46 which are slidably engageable within the forward edges of the side walls 2| and 22. This tongue and groove arrangement permits the front Wall to be removed for the purpose of replenishing the stack of blades within the magazine after it has been consumed. Where desired, the front wall may be permanently connected to the rest ofthe magazine by soldering or spot welding or may be semi-permanently attached by a Well known tab and slot construction.

The razor connecting element I5 is preferably integral with the front wall 23, being a downward extension thereof. The lower edge 41 of the connecting elementI I5 may be provided with a plurality of offset guiding lips 48. Where the element I5 is composed of a resilient material, the lips 48 may be temporarily distorted to engage the forward edge 49 of the razor cover 50 and to thereby position the connecting element I5 and hence the magazine IIJ with respect to the razor 9. As desired, the lips 48 may be permanently spaced from the body ofthe element I5, a distance substantially equal to the thickness of the top wall of the cover 50. The finger 29 is preferably maintained in the inactive position thereof (see Figure 5) by the spring 5I which constitutes a means for movably mounting said finger. The forward end of the spring 5I is connected to the outer end of the nger 29 whilev the rear end of the spring 5I is connected to the side wall 2|. the nger 29 and the rivet 52 and the shape of the spring 5I, the finger 29 may have substantially rectilinear movement through the orifice.

28, rearwardly of the shoulder 36 and forwardly of the second blade (from the front wall) head in the stack.

The thickness of the finger 29 is preferably substantially equal to or slight-ly less than the thickness of the blade at the area where the nger engages the blade and/or the blade head. The lower edge of the finger may be provided with a projection which abuts against the there deformed inner surface of the outer wall and which prevents undesired outward movement of the finger (see Figure 4) A The operation of the first embodiment of the invention, as presently understood, is substantially as follows. With the front wall removed, a stack of blades is placed within the magazine in the positions shown in Figures 2 and 4. When the front wall 23 is put in place the spring I4 acting upon pressure member 44 forcesy V,thev

blades into parallelism with the front blade Vin contact with the rear surface of the shoulder 36.

'Ihe blades are maintained in proper stacked vrelation by the -ribs 3U and 3| and resting upon from the magazine, it may fall upon the blad receiving seat or platform.

Pressure upon the outer surface of the spring 5I opposite the finger 29 inwardly o f the device, causes the finger 29 to laterally displace the foremost blade I3, shifting the same over on to the portion 53 of the bottom wall I8. the right hand edge of the foremost blade I2 becomes aligned with the inner surface 40, manual pressure upon the spring 5I is released and the finger is withdrawn until its inner terminal is in alignment with the right end'edge of the next succeeding blade. Now the pressure of the longitudinal pushing means upon the balance of By reason of the radius betweeny As soon as theV bladesfin" the;A stack'iforces the now 'releasedI blade lforwardlysothatrthe* same may drop through the' opening 4I :by the'j action of :gravity onto"fthebladereceiving"portionsof they razor 9.

Thevspring |'I4 maybe secured in position by a rivet |43 which isintegral withandextruded from-the lower portion |42-of the rear wall |20. The rivet- I 43-may penetrate-the orifice in the saidspringfthereat. The plate I 45 has an inv dentation or lower edge slot which engages upon the key |51 and serves. to distribute the pressure exerted bythe forward ends of.I the spring- 4 against the-rearg surface of the head |21 of the rearmost bladef I I3.Y Thisserves to advance the stackY ||2f aslt-heforemost'- blade is fed therefrom.

The front wall |23 has a pair ofv rearwardly:

extending shoulders4 |36 andv 236. The inner surfaces |31, |38, |39, |40 form the margins of the discharge opening I4|. ,v

As presently understood, the operation of the second embodiment of' the .invention is substan tially. asfollows: assuming theparts tofbe in a position Yshown in Figures 'Tand 8; manual pres` sure upon the finger |29 will shift the ejector I |1 to the right of the magazine (upwardly as seen in Figure 8 and to the left as shown in Figure 10). When the inner edge of the finger |29 becomes aligned with the inner surface |40 of the shoulder' |36 thev inner' surface of-tl-ie ngeni229wili become laligned Vwith the'in'ner' surfacefof'thellftfi side wall- |22.

vWhile we have shown both1 therst and` seciand embodiments ofthe invention` as being.. loaded-from the' front of the magazine, by making the rear wallrem'ovablathe blades may bei loaded from that end. f

Turning'now, thethird embodiment'ofthe invention is illustrated in Figures 13 ande-14,... wherein, for the purpose of avoiding needless.- repetition,parts' corresponding to the lirstfem'-, bodim'ent. are-lgiven` the same reference char.; acters withfthe additionofthe prex 2..`

Inthisv third embodiment, the fingers 48. of. thel rst embodiment are omittedvwith such lossl of their function as. follows: Thus-the razor: connectingy element 2 |5 is -of a width. adaptedi to tlbetween the sides of! the' cover 329, and of such-length that Whenit abutsthe blade shifting' 1ugs-3`39`there is suflicient room for the blade-to drop'andff turn, so that-itY may fall flat on the blad'eplatform4 260. In use `the outer or for-y ward surface of the razor connecting element 2 |5-f is manually maintainedin Contact with the in-j ner surface of the cover top wall 326 during therr` ejecting` or razor loading operation.y

Also in the third embodimentythe rear mar-- ginaledgeof the discharge'opening 24"| is angu-- larly disposed with respect to the plane' of the blade about to be discharged, and angularlydisposedwith respect to the horizontal, so thatv when" thefinger I1 movesv the blade to a position directly rearwardly of the actual opening 24|, it will rest upon the angular surface 24|a and will advance under the action of gravity into and down through the opening 24|. This action occurs before the finger l1 is retracted by VIt may thus be seen that we have provided novel and useful razor blade magazine and razor bladeI constructions. We wish it to be understoodthat we do not desire to be limited to the exact details of constructionV shown and described, for obvious modifications will occur to a person skilled in the art.
