Abstract
Abstract This invention is a tube compressing apparatus. It dispenses the contents of a tube by compressing the tube between rollers. It comprises a housing having fixed at one end a spout to which the open end of a tube is connected. The sealed end of a tube is supported by a clamp provided at the other end of the housing. A platen having a rack bar is supported for reciprocal movement in the housing. A second rack bar is fixed to the sides of the housing. A roller support platen intermediate the housing ends proceeds to compress the tube from the sealed end to the end connected to the spout. This is accomplished by providing a ratchet on the roller support platen which engage the reciprocally movable rack bars carried by the first mentioned platen when moving in the downward direction but is released when moving in the upward direction. A second ratchet is provided on the roller support platen which engages the second rack bar fixed to the sides of the housing to prevent any upward movement of the roller support platen but is released when the roller support platen is moving in the downward direction.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
189 words
A tube compressing apparatus, comprising: a housing; spout means in said housing fixed at one end thereof, said spout means having means for connecting an open end of a tube; clamp means in said housing fixed at the other end thereof, said clamp means operable to hold the sealed end of the tube; first rack bar means mounted on a movable platen in said housing for reciprocal movement intermediate said spout means and said clamp means; second rack bar means fixed to said housing intermediate said spout means and said clamp means; roller support means in said housing intermediate said spout means and said clamp means for compressing the tube connected between said spout means and said clamp means; first ratchet means on said roller support means engaging said first rack bar means to move said roller support means in one direction of said reciprocating movement of said first rack bar means; and second ratchet means on said roller suppport means engaging said second rack bar means to prevent said roller support means from moving in the other direction of said reciprocating movement of said first rack bar means.
Claim 2
Dependent Claim
189 words
A tube compressing apparatus, comprising: a housing; spout means in said housing fixed at one end thereof, said spout means having means for connecting an open end of a tube; clamp means in said housing fixed at the other end thereof, said clamp means operable to hold the sealed end of the tube; first rack bar means mounted on a movable platen in said housing for reciprocal movement intermediate said spout means and said clamp means; second rack bar means fixed to said housing intermediate said spout means and said clamp means; roller support means in said housing intermediate said spout means and said clamp means for compressing the tube connected between said spout means and said clamp means; first ratchet means on said roller support means engaging said first rack bar means to move said roller support means in one direction of said reciprocating movement of said first rack bar means; and second ratchet means on said roller suppport means engaging said second rack bar means to prevent said roller support means from moving in the other direction of said reciprocating movement of said first rack bar means.
Claim 3
Dependent Claim
68 words
The apparatus of claim 1 wherein said spout means is further characterized as having a passageway therethrough, one end of said passageway being a spout, the other end of said passageway being enlarged and threaded, a bushing member having a tapered bore threaded into said other end of said passageway, and a coupling member having a longitudinally tapered surface for mating with said tapered bore of said bushing.
Claim 4
Dependent Claim
143 words
A tube compressing apparatus, comprising: a housing composed of base, side, top and door members; a spout discharge assembly mounted on said base; a first platen supported for reciprocating movement over said base; upright rack bars fixed to said platen and longitudinally movable relative to said side members of said housing; rack bars fixed to said sides of said housing disposed parallel to said upright rack bars fixed to said first platen; a second platen, said second platen having an aperture, rollers journaled in said aperture, first ratchet means fixed on said second platen for unidirectional engagement with said upright rack bars, and second ratchet means fixed on said second platen for unidirectional engagement with said rack bars fixed to said sides of said housing; and clamp means on said top member of said housing for securing the sealed end of a tube.
Claim 5
Dependent Claim
143 words
A tube compressing apparatus, comprising: a housing composed of base, side, top and door members; a spout discharge assembly mounted on said base; a first platen supported for reciprocating movement over said base; upright rack bars fixed to said platen and longitudinally movable relative to said side members of said housing; rack bars fixed to said sides of said housing disposed parallel to said upright rack bars fixed to said first platen; a second platen, said second platen having an aperture, rollers journaled in said aperture, first ratchet means fixed on said second platen for unidirectional engagement with said upright rack bars, and second ratchet means fixed on said second platen for unidirectional engagement with said rack bars fixed to said sides of said housing; and clamp means on said top member of said housing for securing the sealed end of a tube.
Claim 6
Dependent Claim
24 words
