Jl F. SHEAHAN RAZOR BLADE CRUSHER Filed Nov. 18, 1939 Patented July 16, 1940 UNITED STATES PATENT OFFICE 4 Claims.
This invention relates to a razor blade Crusher.
An object of the invention is the provision of a device having a housing provided with an opening through which the blades are inserted with the blades falling between a pair oi jaws and supported thereby until means is operated for v moving one of the jaws towards the other jaw for crushing the blades into small pieces so that after` the jaws are released and separated the particles will fall into a container located beneath the crushing jaws.
A further object of the invention is the pro' vision of a device for crushing razor blades between a pair of jaws, one of the jaws being fixed in position while the other jaw is moved into cl..- operative relation with the fixed jaw with means for causing the movable jaw to contact the fixed jaw, a support for maintaining the blade between the jaws forming guides for the movable jaw, means also being employed for preventing lateral displacement of the blade when resting upon the guides, said movable jaw adapted to be orced into engagement with the fixed jaw.
This invention will be best understood from a g5 consideration of the following detailed description, in view of the accompanying drawing forming a part of the specication; nevertheless, it is to be understood that the invention is not confined to the disclosure, being susceptible of such changes and modifications as deiine no material departure from the salient features of the invention as expressed in the appended claims.
In the drawing:
Figure 1 is a view in elevation partly in section 35 of a blade crushing device,
Figure 2 is a horizontal section taken along the line 2 2 of Fig. 1,
Figure 3 is a transverse vertical section taken along the line 3--3 of Fig. l, and
40 Figure 4 is a fragmentary vertical section taken along the line 4--4 of Fig. 1.
Referring more particularly to the drawing, i@ designates generally a frame which is composed of a vertically disposed plate Il, a laterally pro 45 jecting cylinder l2, internally threaded bosses I3, I4 and pairs of horizontally disposed guide rods I5 and I6.
The periphery of the plate II is provided with a groove 20 adapted to receive the free end of a 50 cup-shaped cover, generally designated by the numeral 2l.
A vertical wall 22 of the cover is provided with passages 23-24 to receive, respectively, the guide rods I5 and I6. The outer projecting ends of these rods are threaded, as shown at 25 and 26,
respectively, to receive nuts 21 for securing the V cover tight against the plate I I. The inner ends of these rods I5 and I6 are also threaded, as shown at 28 and 29, respectively, and screwed into the internally threaded bosses I3 and I4, respectively.
A jaw 30 is secured to the inner face of the plate 22 of the cover 2| and is provided with teeth 3| formed complementarly to the teeth 32 formed on a movable jaw 33 which has passages 35 to receive, respectively, pairs of spaced guide rods I5 and I6. These passages `are formed in ears 36 and'31.
It will be noted from Fig. 3 that the ears 31 are closer together than the ears 36 and the space between the guide rods I6 is less than the width oi a blade so that when a blade is inserted through an opening 40 formed in the top 4I of the cover 2 I, the lower end of the blade will rest upon the rods I6 and be supported between th jaws 30 and 33.
A pair of plates 42 project laterally in vertical planes from the inner face of the side wall 22 of the cover 2l and are in close association with the opposite ends of the jaws 30 and 33 in order to prevent the blade after it has been dropped through the openings 40 and after it has rested on the rod I6 from falling laterally and away from the cooperating jaws.
The plunger 45 is slidably mounted within the cylinder I2 and has a portion cut away, as shown at 46, to provide a rack 41. The outer end of the plunger, as shown at 48, is retained to form a closure for the outer open end of the cylinder I2. A pinion or toothed wheel is formed on one end of a shaft 5I The pinion is mounted in bearings 52 formed in the side walls of the cylinder I2.
The shaft 5I extends through an opening 53 in a side wall 54 of the cup-shaped cover 2l and is provided with a crank arm 55 which when rocked will rotate the pinion in one direction. A coil spring 56 embraces the shaft 5I and has one end, as shown at 51, secured to one of the guide rods I5. The other end of the spring, as shown at 58, engages over the lever or arm 55. Thus it will be seen that when the lever is moved in the direction indicated by the arrow in Fig. 1I. pinion 5i] will be revolved in one direction while when the lever is released the coil spring will return the lever to its inoperative position.
A pair of ears 60 project laterally from the back of the jaw 33 and are provided with perforations 6I to receive a pin 63. This pin has a head 63 which rests upon the upper ear 60.. The pin is inserted through a passage 65 formed in the plunger 45 so that when the plunger 45 is reciprocated it will move the jaw 33. The pin 62 in connection with the ears 60 and the passages 65 in the plunger 45 maintains the jaws 33 in vertical alignment with the Xed jaw 30. In this connection, however, the inner end of the plunger 45 merely abuts the rear face of the jaw 33. On the other hand, the inner end of the plunger `may be rigidly secured to the rear face of the iixed jaw.
The wall 22 of the cover 2l is provided with an opening 68 through which is slid a drawer or receptacle 61 with the bottom of the drawer resting upon the bottom of the cover 2l. A manipulating knob 68 is securedy to the front wall 69 of the drawer 67 so that the drawer may be withdrawn periodically to remove the broken blades therefrom.
The operation of my device is as follows: With the drawer 61 in place and the jaw 33 automatically moved away from the iixed jaw 3B by means of the spring 56, the parts are in position to receive a blade which is adapted to be crushed between the jaws. The blade is then slipped through the opening 40 in the top 4l of the cover 2| and'it will fall downwardly and the lower end of the blade will rest upon the guide rods I6. The laterally projecting spaced plates e 42 at the opposite ends of the jaws 3l) and 33 will also not only7 guide the blade to a position directly between the jaws but said plates will also maintain the blade in position.
The arm or lever 55 is then moved in the direction indicated by the arrow shown in Fig. 1 whence the pinion. 50 will be rotated and since it is in mesh with the teeth of the rack 4l, the plunger 45 will be moved' towards the right` in Fig, 1 and thereby force the jaw 33 towardsr the jaw 30. When the ylever has been moved through a suiicient angle the teeth 3| and 32, respectively, of the jaws 3U and 33 will crush the blade into small pieces. At this time the cooperating teeth Til and 1| of the jaw 3l! yand the teeth 'l2 of the jaw 33 will be cooperatively engaged for closing the opening 40, thereby preventing dust and fine particles from being discharged from the housing or cover 2l.
When the arm 55 is released the coil spring 5B which has been wound tight by the movement of the arm 55 will return the arm to its normal cooperative position, as shown in Fig. 1, and the particles from the crushed blades will then fall by gravity into the receptacle or drawer 61. The device is now in position to crush another blade. y
The device may be of the portable type or it can be vso constructed that it may be fixed in position on any suitable support. f
f provided with a slot for the insertion of razor blades to be crushed, a jaw fixed within the housing, a second jaw movable into engagement with the xed jaw, means slidably mounting the second'jaw, means moving the second jaw into and out of engagement with the fixed jaw for causing the second jaw to close the slot when the blade is being crushed.
2. A razor blade Crusher comprising a housing, a jaw fixed within the housing, a second jaw adapted to be moved into engagement with the fixed jaw, ears projecting from the second jaw and provided with passages, rods fixed within the housing and received by the passages for slidably mounting the second jaw, a rack secured to the second jaw, a toothed wheel meshing with the rack, means rotating the wheel in one direction for moving the jaw, a spring reversely rotating said wheel and returning the second jaw to an inoperative position, the housing having an opening for the insertion of blades, the jaws closing the opening when a blade is being crushed.
3. A razor blade Crusher comprising a frame including ra vertically disposed plate and guide rods projecting from said plate, a plunger slid'- ably mounted in the cylinder and provided with a rack, a movable jaw connected with the rack and slidably mounted on the rods, a cover housing the frame and secured thereto, a jaw iixed to the inside of the cover in alignment with the movable jaw, a pinion in mesh with the rack, means rotating the pinion to cause the rack to force the movable jaw into engagement with the iixed jaw, and means reversely rotating the pinion for returning the movable jaw to an inoperative position.
4. A razor blade Crusher comprising a frame including a vertically disposed plate and guide rods projecting from said plate, a plunger slidably mounted in the cylinder and provided with a rack, a movable jaw connected with the rack and slidably mounted on the rods, a cover housing the frame and secured thereto, a jaw xed to the inside of the cover in alignment with the movable jaw, a pinion in mesh with the rack, means rotatingr the pinion to cause the rack to force the movable jaw into engagement with the fixed jaw, means reversely rotating the pinion for returning the movable jaw to an inoperative position, said guide rods projecting exteriorly of the cover, means cooperating with the projecting ends of the guide rod for securing the cover in position, and guide plates projecting from the cover and embracing opposite edges of the jaws for maintaining a blade in position between the jaws.
