Astm i-th fr ehieeterthiei fvehtienfis to'pro vide :a crusher for used-safety'razor blades andthe like that is economical in manufacture, dura ble and emcient in use, andreflned'in appearance.
thoseskilled in the I "These and other objects will. be apparent to -My invention in the construction,- errangement and combinationcfgthej various parts i of the device, whereby, the objects contemplated v. are attainednas hereinafter more fully set forth,

Fi 2 isa fr n t partial. sectional view of 'mydeg ceitlie section being tgkenon they 1me of j Fig. 3 is a top partial sect ional view ofiny safe "fty razor blade crusher: andmore fully illustrates I its construction.
.One of the problemsarising fromtbe use 'of safety razor blades has been'the disposal of the used blades in asafe manner to prevent accidents occurring throughthe careless disposition of the blade. As thevblades are sharp, they may easily I wound an unsuspecting individual and as they are "usually rusty, due to-their contact with water, they are apt to carry dangerous infection. f
1. Some attempts have been made at disposing of g. these bladesby merely dropping them through 40 aj slot in a container, which, however, allows the ;,blade to remain intact thereby oflering the possi- A bilityfof injuring the individual emptying the centaineror the'careless misplacement -of its contents. I have overcome these disadvantages as will be appreciated and asherelnafter more fully 'flsetforth. f
' I have used the numeral II .to designate the v mousing of my device having the ordinary perforated flange H for securing it -to"a wall or like.
.Formedat the top of this housing is a hopper I2 for directing the used blade through a sflot so that it will-drop between parallel pulverlzing rollers and M as shown in Fig.1. It will be noted by reference to the drawing that there is 3 a slot it in one of the end walls of the hopper l2.

'I'he numeral It designates an enlarged open ing adjacent the slot Ii at the top of the housing ID for allowing the admittanceof razor blades,"
having a reinforced back, to'the pulverizing rollersil and ll. 'Thenumerafl'l'designates two. 7 protrusions formed in the end wall of the hopper I I2 extending into and partially closing, at one point. the slot l5. As the device is made of thin sheet metal "or the like, there will be Tsuillcientv springtothe metal to allow a reinforced back razor blade to. be insertedlengthwlse into the device with thereinforcenient entering the opening it, the blade portion forcing the twoprotrul-sions I1 apartto allowthe-blade to be pulverized .by'the rollers I3 and I4; 'Iheposition ,of the blade isjshown inri'g. 2 of the drawingfby dotted lines'and 1 have designated this blade by the n-u-j m'eral It. The numeral llldesignatesr a guide bar li gidlysecured to thehousing to for keeping the" a gear 20.. The shaft 23 extends beyond and through the housing It and has secured to its outer extremity a manually operated crank arm 2| as shown in Fig.3" ofthe drawing.- I have used the numeral 25 to designate a container secured to the lower open end of the housing ill below the rollers 13 and I4 for receiving the pulverized fragments of the blades "crushed by the rollers. This container has lugs 26 on its rearward upper end portion for engaging the receiving slots cut in the lower rear portion of the housing I.
The numeral 21 designates a screw, bolt or the like rigidly securingjthe container 25 to the'forward lower end portion of the housing It as shown in the drawing. I
The practical operation of my device is as follows. The flange II is'secured to a wall or like by 'a suitable means so that the housing It is in a normal upright position with the hopper l2 at tion of the crank handle will cause the rollers to rotate inwardly and downwardly thus forcing the .within the hopper so that it may be completely.
destroyed. These pulverized particles of razor blade will drop into the container 25.
when it is desired to pulverize one of the reinforced back safety razor blades, the razor blade is placed in vertical position so that the reinforcement is within the opening ll and gentle pressure is applied to the end 'Of the reinforce-- ment strip thereby forcing the protrusions l'l apart and allowing the blade to be engaged by the rollers I3 and I. The guide bar I. will.
- keep the blade in alignment and will also guide the razor blade so that its thin portion will always be engaged by the rollersi3 and i4 as'will be appreciated. By the use of the guide bar all of the thin part of the blade will be pulverized and deposited in the lower container 25. The reinforced portion from which the blade has been brokenwill drop into the container 28. By this arrangement, the reinforced portion of the razor blade can not injure or damage the device and as it is smooth and harmless, there is no objection to this portion of the razor blade. By pul verizing the steel of the blade, a great amount of the fragmentary particles can accumulate in the container 25 as the particles will settle allowing the destruction of more razor blades before it is necessary to empty the container. This container may be emptied from time to time by detaching it from the housing III or it may be in communication with a suitable depository. Thus it will be seen that I have provided a crusher for used safety razor blades that cmnpletdy Di l.
verizes the dangerousiportion of the blade, that I is adaptable to all types of safety razor blades; that. is safein use and that prevents accidents caused by the misplacement of the used safety razor blade.
Some changes may be made in the construction and arrangement of my improved crusher for used safety razor blades without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modmed forms of structure or use of mechanicalequivaients which may be reasonably included within their scope. I claim:
1. In a crusher' for used safety razor blades, a housing, alhopper-in the upper portion" of said housing, two longitudinally parallel rollers rotatably mounted in said'housing positioned below said hopper, a means for manually rotating said rollers, teeth on said rollers, a vertical slot opening in one side of 'said hopper, and a vertical razorvblade guide bar in said housing and back of said slot openin a 2. In a crusher for used safety razor blades, 9. housing, a hopperin the .upper portion of said housing, two longitudinally parallel rollers rotatably mounted in said housing and positioned below said hopper, ameans for manually rotating said rollers, teeth'on said rollers, and a ver-; tical slot opening in one side of said hopper for permitting a razorblade to extend through it and in engagement with said rollers during the crushing process.
3. In a crusher for used safety razor housing, a hopper in housing of spring metal, a vertical slot opening blades, a
in one, side of said-hopper for permitting a razorblade to extend through it and during the crushing process, lug elements formed on said hopper and extending into said vertical slot, two parallel toothed rollers rotatably mounted in said housing and positioned below said hopper, and a means for rotating said rollers.
