GRINDING OR POLISHING MACHINE.
Specification of Letters Patent.
Patented April 24, 1906.
Application filed August 7, 1905. Serial No. 273,174.
shiftable hood which may be moved lengthwise of the suction-pi e to bring the center of the hood in line wit grinding or polishing wheels located at different points on the drive-shaft.
Another object is to facilitate exchanging wheels on the shaft without displacing any part of the hood.
Another object is to provide simple and effective means for varying the size of the paszo sage-way from the hood to the suction-pipe,
so as to pro erly distribute the suction among a plura ity of hoods, and another object is to improve certain details of the'hood.
The invention is exemplified in the struc- 2 5 ture hereinafter described, and it is defined in the appended claims.
In the drawings forming part of this specification, Figure 1 is a front elevation of a grinding or polishing machine the wheels of which are provided with hoods and adjuncts embodying our invention. Fig. 2 represents a fragment of the suction-pipe, showing a rovision for connecting the down-leg of the Iiood slidably on the pipe. Fig. 3 is a side 3 5 elevation of an embodiment of our invention.
Fig. 4 is a rear view of the hood from the direction shown by the arrow in 1* ig. 5. I 1g. 9 is a perspective representation of the slide used on the foot of the down-leg to vary the .40 passage-way from the hood to the suction- A grinding-wheel 1 is shown located close to the 1ournal-box of the drive-shaft on one side of the machine, and a smaller wheel I is shown attached to the rejecting end of the shaft on the opposite Slt' e of the machine.
The hood coin rises an approximately hemispherical shel 2, located behind the wheel, and an a proximately horizontal exrnerges with the vertical part and is located beneath the wheel. A narrow roove 4 is formed in the back part of the hoo and a wider conduit 5 conjoins with the narrow conduit 4 and communicates with the horizontal extension 3. The conduits 4 and 5 converge to the down-leg 6, with which they unite. The lower end of the down-leg is attached to a slide-plate 8, and the connection is strengthened by braces 7. A suctionpipe 9 is adapted to draw of! dust from the hoods, and it has a flattened side extension or enlargement for each down leg, as shown at 10. An elongated opening 12 is formed through the flat surface of the suctioni136, and the downturned flanges 11 form s lideways for plate 8 of the down-leg. A plate 14 is placed below plate 8, as shown in Figs. 1 and 3, and it is provided with an opening 16, (shown in Fig. 5,) which is about the same size and shape as the discharge opening through the down leg. The late 14 is longer than plate 8. It is slidab e with relation to the plate 8, and it is preferably provided with an upturned flange or ledge 15, by means of which it may be manipulated.
Dust formed by the grinding or polishing wheel is progected into the hood by centrifugal force. onie of the particles fall into the horizontal extension 3 and descend through conduit 5 to the (lO\V11-l6g, while other particles are )rojected into the back part of the hood and drawn into the narrow conduit 4.
W hen the grinding-wheel is set close to the journal-box of the shaft, as shown at the left side of Fig. I, the slide 8 is in one extreme position of lateral adjustment, and when a wheel is on the end of the shaft away from the boxing, as shown at the right side of Fig. 1, the slide-plate and the hood are moved to the opposite extreme, and the narrow groove or conduit- 4 is brought into alineinent with the wheel. .ln shifting the hood the lower end of the down-leg maintains communication with the suction-pipe through the elongated opening 12, and the plate 8 acts as a closure for all of the opening that would otherwise be uncovered.
The opening 16 through plate 14 may be placed inalineinent with the down-leg dischargc-opening, in which case the passa e from the down-leg will be free and unobstructed, or it may be moved to one side to a greater or less extent, so that the solid part of the plate 14 will diminish or entirely cut off and the suction-pipe. This provision is useleading from hoods nearer the suction, so as to equalize the suction in each of the.hoods. It also provides for entirely cutting off suction from wheels not m use.
In Fi 1 the plate 14 is adjusted on the right si e of the machine to leave the communication from the hood to the suctionipe Wide en, and on the left side of the mac ine the ssh e is moved to artly close the opening. The late 14 will or marily slide with plate 8 in a justing the hood laterally on the suction pipe; but means ma be provided for securing the two plates toget er in any desired correlation.
The a proximately hemispherical configuration o the upper art of the hood permits the removal and rep acement of a grinding or polishing Wheel without removing the hood or any art thereof or Without swinging any part 0 the hood aside, and the contracted conduit 4 intensifies the suction at the back of the hood to catch the particles that would otherwise tend to carry upward over the wheel. A fla 13 may be suitably connected with the hood in any desired position, and it mag be swung or otherwise moved nearer to or arther from the wheel, so as to intercept any heavy particle difficult of control by suction.
What we claim as new, and desire to secure by Letters Patent, is V 1. A hood for grinding or polishing wheels, extending behind, below and partly above the wheel, a down-leg leading from the lower part of the hood, and a narrow depression in the back part of the hood extending downward to the down-leg and forming a laterallycontracted conduit.
2. A hood for grinding or polishing wheels,
comprising a concave shell in an approximately vertical positlon, a horizontal extension of the lower part of the shell, a down-leg leading from the lower part of the hood and the extension thereof, and a narrow depression invthe back part of the hood extending downward to the down-leg and forming a laterally-contracted conduit.
3. A hood for grinding or polishing wheels,
4. In a grinding or polishing machine, the combination of a horizontal suction-pipe, a grinding or polishing Wheel mounted on a shaft parallel with the suction-pipe, an approximately hemispherical hood for the wheel, and a down-leg for the hood communi eating with the suction-pipe and slidable lengthwise thereof.
5. In a grinding or. polishing machine, the
combination of a horizontal suction-pipe, a-
slidable lengthwise of the pipe lll'GODllllUl'llcation therewith.
7. In a grinding or polishing machine, the combination of a horizontal suction-pipe, a grinding or polishing wheel the axis whereof is parallel with the suction-pipe; and an approximately hemispherical hood for the wheel communicating with the pipe and movable lengthwise thereof. 1
8. In a grinding or polishing machine, the combination of a suction-pipe having a flat side, a dust-collecting hood, a down-leg for the hood, a plate on the lower end ofthe' down-leg slidable on the fiat side of the pipe, and an apertured plate slidable between the plate of the down-leg and the fiat side of the, pipe for controlling the opening between the down-leg and the pipe.
9. In a grinding or polishing machine, the combination of a suction pipe having an elongated side opening, a dust collecting hood, a down-leg for the hood, a plate on the lower end of the down-leg slidable on the open side of the pipe, and an apertured plate slidable between the plate of the down-leg and the pipe for controlling the passage-way from the down-leg to the pipe.
In testimony whereof we sign our names in the presence of two subscribing witnesses.
