Abstract

Abstract A glass breaking machine having a hammer mill removably mounted within the machine. The hammer mill includes multiple series of hammers each following an orbital pattern offset from the remaining hammers. A hammer mill housing opening enables hammer mill removal for service purposes. Similarly, each hammer is readily detachable from the hammer mill. A chute is swingably mounted to enable classifying of the fractured material according to color or other criteria.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 179 words
A glass breaking machine for sorting different colored glass and comprising, a bin for reception of glass to be broken, a hammer mill housing below said bin, a hammer mill disposed below said bin and journalled within said hammer mill housing, said hammer mill including multiple series of hammers with each series radially spaced from the hammer mill axis of rotation, said hammer mill including a main shaft, said hammer mill housing defining an opening of a size permitting outward axial passage of the hammer mill for servicing purposes, a closure plate removably affixed to the hammer mill housing and normally closing said opening, and bearing means on said closure plate for the hammer mill main shaft, additional bearing means on said hammer mill housing opposite the first mentioned bearing means with the bearing means jointly supporting said main shaft, a discharge chute, and means swingably coupling said chute to the housing lower end whereby said chute may be manually arcuately positioned for the discharge of broken glass into one of several receptacles each containing glass of one color.
Claim 2
Dependent Claim 179 words
A glass breaking machine for sorting different colored glass and comprising, a bin for reception of glass to be broken, a hammer mill housing below said bin, a hammer mill disposed below said bin and journalled within said hammer mill housing, said hammer mill including multiple series of hammers with each series radially spaced from the hammer mill axis of rotation, said hammer mill including a main shaft, said hammer mill housing defining an opening of a size permitting outward axial passage of the hammer mill for servicing purposes, a closure plate removably affixed to the hammer mill housing and normally closing said opening, and bearing means on said closure plate for the hammer mill main shaft, additional bearing means on said hammer mill housing opposite the first mentioned bearing means with the bearing means jointly supporting said main shaft, a discharge chute, and means swingably coupling said chute to the housing lower end whereby said chute may be manually arcuately positioned for the discharge of broken glass into one of several receptacles each containing glass of one color.
Claim 3
Dependent Claim 27 words
The machine claimed in claim 1 wherein said additional bearing means on the hammer mill housing is adapted for sliding reception of the hammer mill main shaft.
Claim 4
Dependent Claim 58 words
The machine claimed in claim 1 wherein said hammer mill comprises plates secured to said main shaft at widely spaced intervals therealong, hammer support rods removably mounted on said plates, each series of hammers carried by a support rod, spacer collars of different lengths removably mounted on said support rods to effect desired lateral spacing of said hammers.
Claim 5
Dependent Claim 29 words
The machine claimed in claim 3 further including end plates on said main shaft located proximate the shaft ends to protect the shaft supporting bearing means from glass particles.
