Abstract

Abstract A machine for washing and laundering garments on hangers comprises a substantially vertical conveyor for lifting a garment on a hanger, transferring the hanger to a stationary conveyor along which it travels at two speeds through spraying chambers and dripping chambers, a transfer pulley to transfer the hanger from the stationary conveyor to an endless conveyor, further spraying chambers, and dripping chambers through which the hanger passes to a drying chamber to dry the garment on the hanger or set a coating thereon.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 90 words
Apparatus for processing garments on hangers comprising means for transferring hangers each carrying a garment to be processed from a supply region where the hangers are randomly relatively closely grouped onto traversing conveyor means with successive hangers disposed in spaced relationship along said conveyor means, a treatment station embodying successive liquid spray and drip compartments, means for intermittently advancing said hangers along said conveyor means at relatively different speeds in the respective chambers, and means for extracting said hangers from said conveyor means and passing them through subsequent treatment stations.
Claim 2
Dependent Claim 90 words
Apparatus for processing garments on hangers comprising means for transferring hangers each carrying a garment to be processed from a supply region where the hangers are randomly relatively closely grouped onto traversing conveyor means with successive hangers disposed in spaced relationship along said conveyor means, a treatment station embodying successive liquid spray and drip compartments, means for intermittently advancing said hangers along said conveyor means at relatively different speeds in the respective chambers, and means for extracting said hangers from said conveyor means and passing them through subsequent treatment stations.
Claim 3
Dependent Claim 152 words
Apparatus for processing garments on hangers comprising traversing conveyor means, means for transferring hangers each carrying a garment to be processed from a supply region where the hangers are randomly but relatively closely grouped to said conveyor means including means for extracting said hangers one at a time from said supply and disposing them in spaced relation along said conveyor means, means for intermittently advancing said hangers along said conveyor means, means providing a first processing station wherein said hangers on said conveyor means are passed through liquid spray and drip compartments, means transferring said hangers in turn from said conveyor means to an endless conveyor, means providing a second processing station wherein said hangers on the endless conveyor pass through further liquid spray and drip compartments, means subsequently transferring said hangers to further conveyor means, and means providing a drying chamber through which the hangers move on said further conveyor means.
Claim 4
Dependent Claim 152 words
Apparatus for processing garments on hangers comprising traversing conveyor means, means for transferring hangers each carrying a garment to be processed from a supply region where the hangers are randomly but relatively closely grouped to said conveyor means including means for extracting said hangers one at a time from said supply and disposing them in spaced relation along said conveyor means, means for intermittently advancing said hangers along said conveyor means, means providing a first processing station wherein said hangers on said conveyor means are passed through liquid spray and drip compartments, means transferring said hangers in turn from said conveyor means to an endless conveyor, means providing a second processing station wherein said hangers on the endless conveyor pass through further liquid spray and drip compartments, means subsequently transferring said hangers to further conveyor means, and means providing a drying chamber through which the hangers move on said further conveyor means.
Claim 5
Dependent Claim 46 words
The apparatus defined in claim 2, wherein said traversing conveyor means is arranged at a higher level than said supply, and said means for transferring the hangers from said supply comprises hoist means for lifting said hangers to said traversing conveyor means one at a time.
Claim 6
Dependent Claim 38 words
The apparatus defined in claim 2, wherein said traversing conveyor means comprises fluid pressure actuated means connected to drive a reciprocable member having spaced pivoted pawls therealong for engaging and advancing said hangers when moving in one direction.
Claim 7
Dependent Claim 26 words
The apparatus defined in claim 2, wherein said endless conveyor is mounted on spaced drums, and intermittent drive means is connected to one of said drums.
Claim 8
Dependent Claim 35 words
The apparatus defined in claim 2, wherein said hangers are mounted on a downwardly inclined rod in the supply so that they tend to slide toward said means for transporting them to the traversing conveyor.
Claim 9
Dependent Claim 22 words
The apparatus defined in claim 6, wherein vibrator means is provided for said rod to aid said downward movement of said hangers.
Claim 10
Dependent Claim 21 words
Apparatus as defined in claim 2, wherein means is provided for periodically raising and lowering spray devices in the spray chambers.
