Definitions
- the invention relates to guides for grinding-machines for grinding the flats of carding-engiues and similar machines, which are preferably made of steel and have narrow level or flat guiding-surfaces, against which the guiding-surfaces of the flat are held during the grinding of the surface of the wire clothing of the flat and so that the flat is not tipped or given any axial movement during the grinding operation.
- My present invention does away with this mixed condition of construction by providing the grinding device or machine with guides which are adapted to cooperate with guiding-surfaces upon the flats, which are made with especial reference to use in conjunction with the guides of the grinding-machine and for no other purpose, while the flats also are pro- Vided with the usual type of guiding-surfaces or surfaces resembling such type, which are not used in conjunction with the guides of the grinding-machine, but are only used in conjunction with the guiding devices of the carding engine.
- This provision of individual surfaces upon the flats permits the guides of the grinding machine or device to be simplified in design and construction and increased in effectiveness and wear, while a perfect mechanical relation between the thing to be ground and the guides is obtained.

GUIDE FOR GRINDING-MACHINES FOR GRINDING FLATS.
SPECIFICATION forming part of Letters Patent No. 684,702, dated. October 1 5, 1901.
Application filed January 12, 1901. Serial No 43,020. (No model-l I To aZZ whom it may concern:
Be it known that I, CHARLES MILLS, a citizen of the United States, residing at Newton, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Guides for Grinding-Illachines for Grinding Flats, of which the fol lowing is a full, clear, and exact description, reference being bad to the accompanying drawings, forminga part of this specification, in explaining its nature.
The invention relates to guides for grinding-machines for grinding the flats of carding-engiues and similar machines, which are preferably made of steel and have narrow level or flat guiding-surfaces, against which the guiding-surfaces of the flat are held during the grinding of the surface of the wire clothing of the flat and so that the flat is not tipped or given any axial movement during the grinding operation.
Heretofore, so far as I am aware, there have been used for grinding the wire surface of flats having guiding-sit rfaces upon their faces guides attached to the grinding devices which have had'two guiding-surfaces, with an interposed shoulder,or which have been curved, and these guides have been used in conjunction with guidiugsurfaces of flats which are used in governing the feeding and presentation of the flats to the main cylinder of the cardingengine in the carding operation of the machine. In other words, the guides of the grinding-machine have been fashioned and organized to meet the flat-guiding conditions of the carding-engine. My present invention does away with this mixed condition of construction by providing the grinding device or machine with guides which are adapted to cooperate with guiding-surfaces upon the flats, which are made with especial reference to use in conjunction with the guides of the grinding-machine and for no other purpose, while the flats also are pro- Vided with the usual type of guiding-surfaces or surfaces resembling such type, which are not used in conjunction with the guides of the grinding-machine, but are only used in conjunction with the guiding devices of the carding engine. This provision of individual surfaces upon the flats permits the guides of the grinding machine or device to be simplified in design and construction and increased in effectiveness and wear, while a perfect mechanical relation between the thing to be ground and the guides is obtained.
I will now describe my invention in connection with the drawings, wherein- Figure l is a view in section and elevation upon the dotted line 1 l of Fig. 2, showing the grindingroll, the roll-guides, flats, and mechanism for holding the flats against the guides. Fig. 2 is a view principally in rear elevation of portions of the grinding mechanism and carding-engine, showing the relation of the flats to the grinding-roll, one of its guides, and to the carding-cylinder and flexible bend. Fig. 3 isaviewin perspective, enlarged, showing one of the checks or side pieces of the flatgrinding mechanism and a portion of aguide attached thereto. Fig. & is a view in perspective of one end of a flat to show the guidingsurfaces which are used with the grinding devices. Fig. 5 is a view representing the relation of the grinding-roll, one of its guides, and the flat during the operation of grinding the surface of the flat. Fig. 6 is a view representing the relation of a flat, flexible bend, and carding-cylinder during the operation of the carding mechanism.
It will not be necessary to describe the construction of the grinding apparatus in detail, as the improved guides may be used in conjunction with any of the ordinary types of flat-grinding machines in use.
Referring to the drawings, A represents one of the guides. (It will be understood that each grinding-machine has two-one upon each side.) These guides preferably are made of steel, and they are attached to the grinding-machine in any desirable way. 1 have represented them as secured to the checks or surfaces upon its faceviz., the guiding-surfaces C C, which are the ones which come into contact with the guiding-surfaces of the guides, as represented in Fig. 5, and the guiding-surfaces C C, which are used only in conjunction With the bends or guides of the carding-engine. The flats are held with the guiding-surfaces O O in contact with the guidingsurfaces of the guides in any desired or usual Way during the grinding of the flats by the grinding-roll D.
It will be understood that the flats are held against the straight or level surfaces of the guides as they are presented to the grindingroll of the machine and that they are not tipped or axially moved with respect to the roll by the guides during the grinding movement, but have a continuous movement of all their parts in the same direction during the grinding operation.
Having thus fully described my invention,
I claim and desire to secure by Letters Patent of the United States 1. In a machine for grinding the flats of carding-engines, guides having a fiat or level guiding-surface adapted to receive guidingsurfaces on the face of the fiat and guide said flat to the grinding mechanism, as described.
2. A machine for grinding the flats of carding or similar machines, having guides provided with narrow flat or level guiding-surfaces, in combination with a flat provided with guiding-surfaces adapted to cooperate only with the flat or level guiding-surfaces of said guides, as set forth.
CHARLES MILLS.
