GRINDING-MACHINE.
SPECIFICATION forming part of Letters Patent No. 570,110, dated October 2'7, 1896.
Application filed January s, 1896.
To all whom it may concern:
Be it known that 1, JOHN IV. TERRY, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Grinding-Machines; and I do hereby 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.
Y My invention relates to what are commonly known as wet grinding-machines, that is to say, the class of grinding-machines in which the periphery of the grinding-wheel is kept moistened while in use, and has for its ob-' ject to improve the construction and operation of this class of machines. \Vith'this end in view I have devised the novel grinding-machine of which the following. descrip tion, in connection with the accompanying drawings, is a specification, numbers being used to designate the several parts.
Figure 1 is a side elevation of my novel grinding-machine, the power-shaft'being in section. Fig. 2 is a section on the line '90 in Fig. 1, and Fig. 3 is a section on the line 3 y in Fig. 2. r
1 denotes the grinding-wheel, which is carried by a shaft 2, to which power maybe applied in any suitable manner, as by a belt running over a shaft or counter-shaft, which is not shown, as the means for driving the machine forms no portion of my present i11- vention. The shaft is journaled on a bedplate 3, resting on a casing 4, which preferably incloses the lower portion of the grind ing-wheel and the trough, which is designated by 5. This trough rests in ways 6 on a vertically-movable table 7, the ways holding the trough firmly in place at all times, but permitting it to be moved in and out, when the table is at the lowered position, through a door 8 at one end of the casing.
9 denotes a guard which is made integral with or attached in any suitable manner to the casing and which extends down below the bottom of the grinding-wheel, in fact, far enough down so that the bottom thereof will 50 be below the surface of the water in the trough when the latter is in the operative po- Serial No. 574,694. (No model.)
sition. This guard incloses the sides and ends of the grinding-wheel, as clearly shown in Figs. 2 and 3, and acts to catch all the surplus water picked up by the grinding-wheel and carry it back into the trough. In fact,
it wholly prevents any spattering of water from the trough and waste of water Within the casing and prevents surface agitation of the water by the wheel from causing any overflow.
It is of course desirable in machines of this class that only a small portion of the periphcry of the grinding-wheel should be immersed in the Water, so that while the periphery of the wheel shall be kept wet very little surplus water will be picked up by the wheel, and it is likewise preferable that when the machine is not in use the grinding-wheel should be wholly out of water. It is furthermore well understood that there is more or less waste of water from the trough continually by evaporation and by being thrown from the stone in use. I11 order that-a small portion only of the periphery of the grindingwheel need be immersed in water, that the grinding-wheel may be kept wholly dry when not in use, and that the trough may be raised at any time, so that a small portion of the periphery of the grinding-wheel may be im- 8o mersed in water without the necessity for frequent filling of the trough, I provide simple and convenient means for raising the trough and holding it at any required position without stopping the grinding-wheel. The table 8 5 is carried by a vertical rack 10, which is adapted to slide in a guide 11, itself supported by a cross-piece 12, secured to the opposite sides of the casing, as clearly shown in Fig. 2.
13 denotes a shaft which is journaled in the guide and in the casing and which carries a pinion lat, adapted to engage the rack and on the outer side of the casing a ratchetwheel 15.
16 denotes a lever, the lower end of which 5 is mounted on shaft 13, but is free to turn thereon, and which carries a pawl 17, adapted to engage the teeth of the ratchet-wheel, the pawl being retained in engagement with the teeth by a spring 18.
It will be noted that forward movement of the lever, that is, movement toward the left,
as seen in Fig. 1, will carry the ratchet-wheel forward through the engagement therewith of the pawl and will rotate the shaft and pinion, which will raise the rack, the table, and the trough.
19 denotes a rack which is adapted to be engaged by the lever to lock said lever and with it the shaft, trough, &c., at anyposition in which they may have been placed.
20 denotes a hand-piece at the upper end of the lever for convenience in operation.
In the drawings the trough is shown at the operative position, that is, a position in which a small portion of the periphery of the grindin g-wheel is immersed in the water. It is obvious that a slight movement of the lever toward the left, as seen in Fig. 1, will raise the trough still higher, so that more of the grinding-wheel will be under water, the parts being of course locked in position by engaging the lever with rack 19 as soon as the trough has been raised high enough. Should the water in the trough have become so low that it will not reach the grinding-wheel when the lever has been moved to the extreme left, as in dotted lines in Fig. 1, the operator holds the ratchet-wheel 15 with his hand, which may be done without the slightest difficulty, disengages the lever from the ratchet and moves it backward from the position shown in dotted lines to the position shown in full lines, the pawl slipping over the face of the ratchet-wheel. hen the parts are in this position, forward movement of the lever will raise the trough again. Should it be required to remove the trough at any time or to partially remove it, as for the purpose of filling, the operator lowers it as much as may be required by disengaging the lever from rack 19 and moving it to the extreme right. Should this not lower the trough far enough, the operator holds the ratchet-wheel with his hand, disengages the pawl, and either lowers the trough by means of the ratchet-wheel or swings the lever forward, perm ittin g the pawl to engage the ratchet-wheel as far forward as possible and then moves the lever backward again, allowing the trough to descend while under the control of the lever. The trough is removed by opening door 8 and sliding the trough in the ways on the table.
llavin g thus described my invention, I claim- 1. In a grinding-machine the combination with a trough and a table by which it is supported, of a vertical rack rigidly connected to the under side of the table and by which said table is carried, a guide in which the rack may slide freely, shaft 13 carrying a pinion which engages the rack and a ratchetwheel 15 and a lever mounted on said shaft and carrying a pawl engaging the ratchetwheel by which the trough may be raised or lowered.
2. The combination with the trough, the table, a rack 10 by which the table is carried and a guide in which said rack may slide, of a shaft 13 carrying a pinion which engages said rack and a ratchet-wheel, a lever mounted on the shaft and carrying a pawl engaging the ratchet-wheel and a rack 19 by which the lever and with it the shaft, rack 10 and the trough may be locked at any desired adjustment.
3. The combination with the grindingwhecl, the casing having a door 8, the trough and a table having ways in which the trough may slide, of a rack by which the table is carried and means for raising and lowering said rack and with it the table and trough and means for locking said parts at any desired adjustment so that more or less of the periphery of the grinding-wheel may be immersed in water and when at the lowered position the trough may be moved outward in the ways and through the door for the purpose of filling.
4. The combination with the grindingwheel, the casing, the vertically-movable table and the trough, of a guard 9 secured to the casing and inclosing the, sides and front and rear portions of the periphery of the wheel and extending below the bottom of the said wheel so that when the edge of the latter is immersed in the water waste of water within the casing is wholly prevented.
In testimony whereof I affix my signature in presence of two witnesses.
JOHN XV. TERRY.
