THOMAS MOONEY, OF DAYTON, OHIO.
APPARATUS FOR GRINDING TlLE" i SPECIFICATION forming part of Letters Patent No. 754,591, dated Maren 15,1904.
Application filed Tune l1, 1903.
To all whom it may concern:
Be it known that I, THOMAS H. MooNEY, a citizen of the United States, residing at Day-Y ton, in the county of Montgomery and State of Ohio, have invented certain vnew and useful Improvements in Apparatus for Grinding Tile, Sac.; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accombe hereinafter more fully described.
Preceding a detail description of my invention reference is made to the accompanying drawings, of whichv Figure 1 is a top plan view of my improved rotary grindingmachine.- In this view uprights are shown in section and cross-beams are partly broken away. Fig. 2 is an elevation with portions of uprights broken away, also a portion of the main driving-shaft. The inclosing rim of the machine is shown in section in this view. Fig. 3 is an elevation at right angles to Fig. 2, portions of the uprights, the main driving-shaft, and lever-supports being broken away. Fig. 4 is an enlarged detail View of a portion of the rotary grinding-bed with a series of tile thereon.
Ina detail description of the invention simi'- lar reference characters indicate correspond ing parts. l
v1 designates a rotary grindingbed, which consists of a metal disk supported and secured to a four-armed spider 2.
3 designates an upright shaft which passes through the axis of said bed and is mounted in a lower bearing 19, supported on a base 21.
Serial No. 160,993. (No model.)
Power is imparted to the shaft 3 to rotate the grinding-bed.
A designates a rectangular tile-frame, of
'and adapted to coperate with frames A in holding the tile in bed.
15 designates two upright shafts which are journaled in boxes 16, secured to horizontal beams 11`,which in turn are secured to uprights 12. These shafts 15,together with the frames B, are adapted to be elevated to free said frames from engagement with the frames A by means of hand-levers 23,which are fulcrumcd upon hangers 22, connected to loose collars 14. Collars 14 inclosev the upper portions of the shafts 15 below rigid collars 13, which are secured to -said shafts. As the position on the grindingframes B are shown in Fig. 3 lthey are elevated,
one above 'a frame A. The other frame A is rermoved from beneath its respective frame B.
6 designates astationary rim inclosing the rotary grinding-bed 1 and supported upon an annular base 18. This rim 6 should at all times be on a level with the upper surface of the bed. It is therefore made of laminations or a series of 'layers of wood united in such manner that the uppermost layer may be removed as the grinding-surface of the bed 1 becomes worn away by constant friction in the operation of the machine. Thus the rim and grinding-bed are maintained on a level.
8 designates two feed-tables, each of which is constructed of a series of parallel bars c onnected by marginal bars ,and supported upon uprights. The several sections of tiling 17 are placed upon such tables when it is desired to grind the surface of a plurality of tiling at a single operation, or if a'single tile of the dimensions of one of the rectangular frames A is to be faced or ground said tile is placed upon one of the feed-tables and a frame A is placed over the same in such manner that the marginal bars 4 of said frame project downwardly around the edges of the tile, as shown in Fig. 4. It will be understood that the marginal edges of said frame A should not project so far that they might come in contact with the grinding-bed 1 for obvious reasons. The normal position of the table 8 is slightly below the upper surface of the grinding-bed 1, as is shown in Fig. 3. This is important, for the reason that in the rotation of the tile in the frames A said tables must oer no obstruction to such movement. The table to the right in Fig. 3 contains a frame A with `with the upper surface of the grinding-bed.
This requires a slight movement of said table by means of the foot-lever 9, which has afulcrum 10 and is pivoted to braces 20, projecting from near the inner end of said table. When suitable pressure is exerted upon said lever to elevate the frame A with the tile as described, the said frame, with its contents. is slid off of said table onto the grinding-bed 1 beneath the holding-frame B, care being taken to move the tile-frame A to a proper position to bring the flanges 7 in the right positions to inclose the four sides of the frame B, at which time the frame B is lowered upon said tile-frame A by means of a hand-lever 23. The frame B holds the tile-frame A in a position to rotate on a permanent axisnamely, the shaft l-as the grinding-bed rotates. The tile-frame A, holding-frame B, and shaft 15 rotate together. derstood that the frictional contact between the tiling 17 and the grinding-bed 1 causes said tile to rotate on such axis.
In the operations of the machine the grinding-bed 1 is supplied with a suitable feed of sand and water to cause an abrading-surface throughout the area of said bed. Throughout the operation of the machine the working surface of the rotating'bed is worn away uniformly, and as a consequence the surface of the tiling is ground uniformly throughout. If a plurality of similar slabs or sections of tiling are placed within the frame A, the grinding given each of said slabs is uniform, and the same is true ofl a single slab of tiling of dimensions equal to said frame. The work of grinding tiling by this machine is conse- It will be unquently far superior and more-speedy than the hand operation. In order to obtain the proper movement, the axis of the tile-frame A#to wit, the shaft 15-is placed nearer to the rim of the grinding-bed than to the main drivingshaft 3, substantially as shown in Fig. 1.
Having described my invention, I claim- 1. In a grinding apparatus, a rotary grinding-bed, a tile-frame adapted to encompass the tiling to be ground, said frame inclosing the upper portion of the tiling so that the face of said tiling alone, is in contact with the grinding-bed, a holding-frame engaging the tileframe, a shaft secured to said holding-frame and having suitable journals, said shaft forming the axis of rotation of the tile-frame and the holding-frame, substantially as set forth.
2. In a grinding apparatus, a rotary grinding-bed, a tile-frame consisting of a series of cross-bars inclosed by marginal bars, said tileframe being adapted to inclose a series of tile or a single tile of equal dimensions with the frame, a holding-frame having a shaft rigidly secured thereto, and suitable bearings for said shaft, said shaft forming the axis of rotation for the tile-frame and the holding-frame, substantially as set forth.
3. In a grinding apparatus, a rotary grinding-bed, a tile-frame adapted to hold a plurality of sections of tiling together upon the rotary grinding-bed, a holding-frame secured to said tile-frame, and a shaft secured to said holding-frame, said shaft being the axis of rotation to the tile-frame, and the holding-frame, the holding-frame serving to hold said tileframe in a position to rotate under the action of the grinding-bed, substantially as set forth.

5. In a grinding apparatus, the combination of a rotary grinding-bed, a stationary rim surrounding said grinding-bed, a feed-table located adjacent to said rim, and the upper surface thereof being normally below the surface of the grinding-bed, said feed-table being adapted to support the tile-frames preparatory to said frames being moved onto the grindingbed', means for elevating said feed-table to a position on a plane with the surface of the grinding-bed to permit of the tile-frame and its contents being moved onto said grindingbed, substantially as set forth.

In a grinding apparatus, a rotary grinding-bed, a stationary rim surrounding said grinding-bed, a tile-frame adapted to inclose tiling in a position upon the grinding-surface IIO of said bed, a holding-frame and a shaft adapted to hold said tile-frame on a permanent axis of rotation, substantially as set forth.
