Referring now in detail to the drawings, the reference numeral 2t) denotes a container, the reference numeral 22 a safety razor, and the reference numeral 24 a razor blade embodying the instantinvention.
Pursuant to the instant invention, the novel blade is composite in nature in that it has 'associated therewith structural elements which function to attain the objects pointed out above. In the embodiment shown in the drawings, which is the preferred form of the invention, this composite blade is illustrated as being formed Afrom the blade proper X and thechannel forming member Y. The blade proper X comprises the more or less conventional double edge strip 54. It will be understood that the invention may be used with any other type of blade, if desired, and that the specification should be read with this thought in mind. The strip 54 is provided with conventional locating means, Vsuch as recesses 56 in the drawings. These recesses 56 are of such depth, and so spaced from each other at a given end, that they slidably receive the vertical guide ribs 46 of the container, the relation being such that a minimum of lateral shifting of the blades is permitted.
The second' `element of the composite blade is the channel forming member Y which adapts the blade proper for the attainment of the objects of the'invention. This member Y comprises 'downwardly 'projecting lelements which are shown in the preferred embodiment of the invention 1 which has been weakened by the slot 64 and extends across the center line of the blade and for the length of the two flanges 58.
The anges 58 and the element 60 are shown integral to form generally a U-shaped channel 57, although this is not essential. The Harige 58 rigidifies the blade longitudinally. This rigidication enables the strip 54 to be made from very thin gauge material and still maintain substantially the same rigidity of a blade made of conventional blade material. The channel member Y also serves to provide an improved method of stacking the blades in a container and an improved method of locating the blade in a razor, as will be hereinafter pointed out.
The blade proper X and the channel member Y have been shown as separate pieces which are secured together, although this is not necessary. The channel member Y may be secured to the blade proper X in any conventional or desired manner. In the illustrated embodiment this securement is effected as follows: The channel member Y is provided with two upstanding tabs 62 and the strip 54 is provided with slots to receive the tabs, such as the slot 64 shown in the drawings. The tabs 62 are inserted into the slot 64 and folded over as shown in Fig. 13 to secure the channel member Y to the strip 54.
The container comprises a casing having side walls 26 and end walls 28, the casing thus resembling a box. The top Wall 21 of the container has a slot 23 opening into the extracting zone and terminating short of the right end wall 28, and the bottom wall 2S of the container has a slot 27 opening into the loading zone and terminating short of the left end wall 28. For ease in construction the container may be made of two identical sections A and B which are reversed and joined to each other along the line C in any conventional manner, or in a manner which will be pointed out hereafter. This enables the two pieces A and B to be made from the same mold. For a reason which later will be apparent, the end wall at the left (as seen in Fig. l), terminates short of the top and the end wall at the right terminates short of the bottom.
The top of the casing is constructed to function as the extracting zone 30 and the bottom as the loading zone 32. Fresh blades are stacked in the casing above the loading zone and beneath a spring 34 which divides the inside of the casing into a chamber 36 for fresh blades and a chamber 38 for used blades.
The top edge 40 of the left end wall at the extracting zone is shaped to negatively fit the transverse contour of the top surface of the razor cap 206. The bottom edge 44 of the right end wall at the loading zone is similarly shaped. The grooves 45 are provided in side walls of each zone to accommodate the guides 65 and 74 which receive the safety line of the razor as described hereinafter.
The inner surface of each end wall is provided with vertical guide ribs 46 projecting into the casing. The guide ribs of the left end wall are V-shaped on the top as at 47 and those of the right panel are V-shaped at the bottom as at 49.
The upper surface of the right end wall includes a central vertical guide rib 50 between the guide ribs 46 and extends beyond the ends of the guide ribs 46. This rib 50 is tapered at 51 for a purpose which will be hereinafter pointed out. A similar arrangement may be provided with respect to the rib 48 on left end wall since the sections A and B are made from the same mold.
In the present preferred design, the two inverted identi cal moldings A and B are held together by the action of the projections 71 and 80 of the guides 65 and 74 in cooperation with the recsses 71a and 81.
At the loading zone of the container the loading guide is provided. Said loading guide 65 is comprised of a at bottom wall 66 having a central longitudinal slot 67 therein terminating short, of the right end in Fig. l2 of the loading guide 65 to accommodate the handle 100 of the razor 22. A short central slot` 68 is provided at the end of the bottom 66 to accommodate the rib. 48 of the casing.
Side walls 69 are provided throughout the length of the loading guide and are contoured, as at 70, complementary to the grooves 45 of the side walls 26 to fit therein. Outwardly biased resilient projections 71 are struck out of the side wall 69 and snap into the recess 71a in the side walls 26 to retain the loading guide 65 in the loading zone 32 and to hold sections A and B together, as pointed out above. Each side wall 69 is provided with a reach 72 and a rib 73 to form an inverted V, the peaks of these V-shaped reach and rib elements 72-73 are spaced apart a distance less than the distance between the sharpened edges of the fresh blade so that the reaches will not dull the edges.
These reaches 72 are disposed below the lower ends of the guide ribs 46 a distance less than the height of the flanges 58 of the blade 24, so that when the strip 54 of the lowermost blade 24 contacts the V-shaped reach and rib element 72-73, the strip 54 of the next to the lowest blade 24' will be under the control of the guide ribs 46 because of the separations between the lowermost blade 24 and the next to the lowest blade 24' caused by the anges 58 of the next to the lowest blade 24' resting on the strip 54 of the lowermost blade 24. The ribs 73 are spaced from each other a distance slightly greater than the distance between the flanges 58 of the fresh blades 24. The lowermost blade 24 is controlled vertically by the coaction of the spring 34 (acting through other blades or directly as the case may be) and the reaches 72; lateral control is obtained by the co-action of the rib 73 and the anges 58; and longitudinal control at the left is exercised by the rib 48, however it can be moved to the right of Fig. l and out of mouth 32. The ribs 73 are downwardly inclined to guide flanges 58 into the space between them when a new blade approaches the reaches 72.
At its extracting zone the container is equipped with the extracting guide 74 having a top wall 75. The top wall 75 is provided with a central longitudinal slot 76 at one end to accommodate the razor and a short slot 77 at its other end to accommodate the rib 5t). Side walls 7S are contoured, as at 79, complementary to grooves 45 in the side walls 26 of the casing to t therein. Outwardly biased resilient projections 80 are struck out of the side wall 78 and snap into the recess 81 of the side walls to hold the two sections A and B of the container together and to retain the extracting guide 74 in the extracting zone 30.
Reaches 82 project inwardly from the side walls 78 for about one-half the length of the extracting guide and are spaced from each other a distance slightly greater than the distance between the two anges 58 of the blade 24. The reaches 82 are disposed above the ends of the ribs 46, a distance suicient to permit the razor cap 42 to enter. The right ends of reaches 82. serve as a fulcrum about which the strip 54 of blade 24 pivots when moving from a horizontal to an inclined position after the razor has been removed and rotating back again to the horizontal when the next blade is extracted.
Depending from the reaches 82 are two projections 84 pressed out of the reaches 82 and spaced from each other a distance substantially equal to the width of the strip 54 of blade 24 to guide used blades 24 laterally.
Notches 85 are cut out of the reaches 82 at a point spaced from the front thereof. The front edge 86 of the notches 85 are twisted downwardly to provide a limit stop for the used blade. An alternative of this limit stop is shown in Fig. 26 where the front edge 86a of the notch 85a is cut out of the wall and bent down and a detent finger 8611 extends upwardly beyond the bottom of the reach 82.
The spring 34 which separates the fresh from the used blades is adapted to hold the fresh blades substantially perpendicular to the end and side walls but to cant the right ends of the used blades upwardly with respect to the left ends thereof. To accomplish this the spring comprises a central portion 90 (Figs. -1 and 8) including a left stub 91 adapted to slide between the guide ribs 46 of the left end wall. The central portion is also provided with an upwardly extending tongue 92. The central portion 90 has integral therewith on each side thereof side lugs 94 having right toes 98 disposed below the tongue 92. The right toes lie in substantiallythe same horizontal plane.
Used blades abut the top of the central portion 90 and of the stud 93 of the tongue 92 (see Fig. l) and are, therefore, canted to the left. The purpose of the canting is to facilitate entry of used blades after insertion of the rst used blade since subsequently inserted used blades must pass over the last extracted (inserted) one. Also, the right toes 98 have their ends upwardly concave to facilitate the entry and exit ofthe razor in the container.
The spring is of such strength that it will prevent the stock of blades from being loose in the dispenser but will permit some upward and downward movement thereof during loading of the razor and extraction therefrom. The spring also should be strong enough so that when at least one and perhaps four or five blades are missing, the remaining blades both used and fresh, if present, will be securely held in the container.
The novel safety razor preferably used with the blade is shown in Figs. 17 to 25. It will be understood that this razor may be of one piece if desired and the choice is only a matter of ease in assembly. The razor comprises a head 202 and a handle 100. The head 202 comprises a rectangular frame 204 having spaced safety bars 208 and the clamping cap 206 integral therewith at rear piece 209. The rear piece 209 is spaced from and is at the same lowered level as the front piece 210 of the frame 204. The slot 212 in the frame 204 and the slot 214 in the cap 206 is provided to accommodate the rib 48 or the rib 50. Two notches 216 are cut ont of the inner edge of the front piece 210 and two projections 218 depend therefrom for reasons hereinafter mentioned.V
The cap 206 is integral with the frame 204 at 209 and is provided with a central longitudinal rib 220. The rib 220 tapers into the side portions 222 and its front and rear ends are curved as at 224.
The centering bar 200 is' a narrow upwardly convex piece 225 underlying rib 220 and having widened base reinforcement 227. It is of such a width as to snugly receive flange 58 of blade 24. The depressed area 226 is provided with an opening 110 for attachment of the handle 100 to the razor 22. It will be understood that the handle 100 may be attached to the razor 22 in any conventional manner, however, in the embodiment shown, the preferred method of attaching the handle 100 to the razor 22 being as follows: the top portion 102 of handle 100 is inserted into the opening 110 and this top is' swaged over the depressed region 226 at assembly.
Horizontal flange 228 at its front end extends beyond the sides of the piece 225 and is adapted to underly the slots 216 of the front piece 210 of the frame 204. Outwardly curved projections 229 extending downwardly from rear horizontal flange 230 are adapted to form a clamp for the rear piece 209. Portion 232 extends upwardly from theliange 230 to provide a stop for movement of the blade in the razor.
The head of this razor is assembled as follows: The cap 205 is folded over the frame 204. Handle 100 is attached to the centering bar 200 as described above. The centering bar 200 is then assembled on the frame 204 by first placing the flange 230 over the rear piece 209 of the frame while the projections 229 are pressed on the underside of the rear piece 209. The angc 228 is placed on the underside of the front piece 210 and the projections 218 are pressed under the liange 210 to hold the centering bar tightly in the frame 204.
The cap is biased toward the centering bar so that its undersurface at the front ordinarily is closed to the center bar than at the rear, although not necessarily as close v6 as the middle of said undersur'face is to the middle of the centering bar.
The cap is disposed at such a distance from the upper surface of the centering bar for a blade of a given thick- 'ness that when the blade is inserted in the razor between the cap and centering bar the cap will be sprung upwardly whereby the cap and bar will clamp the blade between them and hold it tightly in place due to the inherent resilience of the structure. Moreover, the position of the cap preferably is such that the thickness of the blade used will, when the blade is inserted, cause the undersurface of the front end of the cap to be the same distance from the upper surface of the centering bar as the undersurface of the rear end of the cap is from said upper surface, whereby the cap will be parallel to the safety bars after the blade is inserted. For razors to be used with blades' of appreciably different thicknesses the relationship between the cap andthe centering bar in the empty condition of the razor will have to be alteredg' with thinner blades the rear end of the cap will have to be closer to the centering bar than with the thicker blades.
The operation of the razor, container and razor blade may best be understood from Figs. 4-7. To load the razor it is inserted into the mouth of the loading zone of the dispenser with the safety bars 208 sliding in the contour 70 of loading guide 65. Said contours 70 are located a distance below the lowermost blade such that the undersurface of the cap of the razor is above the upper surface of said lowermost blade, and the top of the entering end of the centering bar 200 is below the lower surface of said blade. The razor is slid all the way into the mouth,` i. e. to'the left as viewed in Fig. 4, and the centering bar 200 thereof slides between the lianges 58 of the lowermost razor blade. The left centering rib 4S lits' into the recesses 212, 214 at the front of the cap and base of the razor and serves as a stop for the left end of the blade 54. The blade 54 then s stopped by the stud 232 by contact of this stud 232 with the right end of the blade 54. Thus the rib 48 stops the razors through blade 54. With the razor so received in the dispenser the lowermost blade will be inserted fully into the razor. The razor then is moved to the right, withdrawing the blade from the mouth of the loading zone, this being made possible because the clamping friction exerted on the blade by the cap 206 and the centering bar 200.
On removal of the lowermost blade the next lowermost blade is' shifted by the spring into lowermost positionl right end wall and, therefore, is in a position to be loaded into the razor. 'I'he contours of the lower surface of the right end wall 28 are shaped to match the contours of the razor cap as aforesaid so that the razor can be smoothly inserted thereunder.
When itv is desired to extract a new blade for blade replacement, the razor with the used blade is entered into the extracting zone at one end of the dispenser, and is guided in such movement by the safety bars 208 entered into recessed contours 79 of the guide 74 (see Figs. 6 and 7).
In this entry of the razor into the extracting zone, the blades engage and angle upwardly slightly the depressed portion 86 until the razor is fully entered at which time the blade will have cleared the depressed portion 86 which is then free to angle downwardly to its normal position to engage its front edge in back of the adjacent edge of the blade. As a result when the razor is moved outwardly the blade will be held against movement therewith by the depressed portion 86 and will drop by gravity onto the stack.
The same result is achieved with the modified form of the extracting zone shown in Fig. 26. The purpose of the depressed portion 86 in both embodiments of the invention is to make certain that the ends of the blade will not slip above the depressed portions and slide out above-the reaches 82 with the razor.
Generally the position of contours 79 is such that the bars 208 when in the grooves 4S, keep the razor in such a position that the depressed portion 86 abuts the end of the razor blade 54 as the razor is taken out of the container.
When subsequent blades are to be extracted from the container, the razor is not blocked by previously inserted blades from entering the mouth of the extracting zone, because the previously inserted used blades are canted whereby the left end thereof lies below the guide ribs of the left end panel. The stub 93 of the spring engage the container cover when no used blade has yet been extracted, and in this position the toe 91 are below the level at which the grooves 45 dispose the cap, so the latter can depress the spring.
To insure proper location of the blade in the razor, dimples 120 may be provided at the left end of loading guide 65. These dimples 120 are forced up from the surface 66 to such a height as to interfere slightly with the projections 229 of the razor as the razor is inserted. These dimples 120 are so located on surface 66 as to be just to the right of projections 229 when the razor has reached the limit of its movement to the left. As the razor is inserted, the projections 2 29 press dimples 120 down while passing over them, after which they spring up again. This snap action informs the user both by Sound ,and feel that the razor has been fully inserted and the blade properly seated in the razor.
