Abstract

Abstract An apparatus for destroying hypodermic needles and like objects, which comprises a rotatable, cylindrical inner cutting body, provided with a bore passing diametrically therethrough, at least one stationary outer cutting body which cooperates with said bore, the outer cutting body being so positioned that two of its sharp cutting surfaces are located at diametrically opposed positions with respect to the inner cutting body and arranged to cooperate with the cylindrical surface thereof and relatively move across the ends of said bore upon rotation of the cylindrical cutting body.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 107 words
An apparatus for destroying hypodermic needles, needleequipped ampules, hypodermic syringes and like objects, which comprises a. a rotatable, cylindrical inner cutting body, provided with a bore passing diametrically therethrough, b. at least one stationary outer cutting body which cooperates with the bore set forth in (a) and which is provided with sharp cutting surfaces, c. the outer cutting body being so positioned that two of its sharp cUtting surfaces are located at diametrically opposed positions with respect to the inner cutting body and arranged to cooperate with the cylindrical surface thereof and relatively move across the ends of said bore upon rotation of the cylindrical cutting body.
Claim 2
Independent Claim 107 words
An apparatus for destroying hypodermic needles, needleequipped ampules, hypodermic syringes and like objects, which comprises a. a rotatable, cylindrical inner cutting body, provided with a bore passing diametrically therethrough, b. at least one stationary outer cutting body which cooperates with the bore set forth in (a) and which is provided with sharp cutting surfaces, c. the outer cutting body being so positioned that two of its sharp cUtting surfaces are located at diametrically opposed positions with respect to the inner cutting body and arranged to cooperate with the cylindrical surface thereof and relatively move across the ends of said bore upon rotation of the cylindrical cutting body.
Claim 3
Dependent Claim 59 words
An apparatus according to claim 1, wherein the stationary outer cutting body is provided with a circular-shaped cavity and two recesses which open into the upper and lower portions of said cavity so as to thereby form sharp cutting edges at the point where the recesses intersect the cavity and the cylindrical cutting body is located in said cavity.
Claim 4
Dependent Claim 41 words
An apparatus according to claim 2, wherein the stationary cutting body is in the form of a tube enclosing the rotatably cylindrical cutting body, and in that the thickness of the material of said tube is reduced around the upper recess.
Claim 5
Dependent Claim 17 words
An apparatus according to claim 1, wherein the stationary cutting body is secured in a frame structure.
Claim 6
Dependent Claim 64 words
An apparatus according to claim 1 which also includes: a. a collecting vessel, b. a tightly sealing lid for said collecting vessel, said lid containing a raised opening, c. a spring-loaded holder which is adapted to press the outer cutting body toward said raised opening whereby needles cut off by said outer cutting body will fall through said raised opening into said collecting vessel.
Claim 7
Dependent Claim 72 words
An apparatus according to claim 1 wherein said rotatable, cylindrical inner cutting body is mounted in a large circular cross-section bore that extends horizontally through said stationary outer cutting body, said large bore being provided with two recesses which are in contact with the upper and lower portion of the bore that extends diametrically through the inner cutting body and removable, stationary blades having cutting surfaces mounted adjacent each of said recesses.
Claim 8
Dependent Claim 33 words
An apparatus according to claim 1 which includes a lever attached to said inner cutting body whereby the rotatable cylindrical cutting body can be rotated about its axis by means of a lever.
Claim 9
Dependent Claim 53 words
An apparatus according to claim 7, wherein said lever is biased by means of a spring which is arranged to return the rotatable cylindrical cutting body to a position in which a through-passing opening is formed by the recesses in the outer cutting body and the bore passing through the inner cutting body.
