Specification of Letters Patent. Patented J 11.3 13 1911 Application filed January 21, 1909.
Serial No. 473,525.
To all whom it may concern:
Be it known that I, JAMES Pncnovnn, a citizen of the United States, and residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Apparatus'for Sawing and Vorking Granite, Marble, Stone, and Analogous Substances, of which the following is a specification.
My invention relates to a combination of devices for separating silt from abrading material, collecting the latter and redistributing it to the saws, and other devices used for working stone and analogous substances.
The apparatus consists of the means illus trated in the accompanying drawings, which form a part of this specification, in which Figure 1 is a side view; Fig. 2 an end view; Fig. 3 a plan view; Fig. 4 an uninterrupted end view of inclined plates for receiving abrading material and delivering it to the saws, andother devices, and the tracks supporting the buckets while delivering the abrading material; Fig. 5 is an enlarged plan of a bucket showing an aperture 19 in its floor; Fig. 6 an enlarged end view of a water supply pipe, spacers, turners, plugs, and the rest pipe for the turners; Fig. 7 a side view of same; Fig. 8 an end view of the distributing mechanism; Fig. 9 an end view of the greater portion of the devices for separating the silt from the abrading material and collecting the latter in buckets while the former'is permitted to fall to the floor of the tank; and Fig; 10 a side view of a suflicient portion of same to convey a clear conception of their functions, and the two ends beinlg duplicates, one description applying to a l.
Similar letters and numerals refer to similar parts throughout the several views.
Referring to Figs l, 2, 3 and 1 Arepresents the main framing of a stone sawing machine, a the superstructure supporting mechanism of the invention, and 8 represents a stone; 1 and 2 represent inclined plates preferably corrugated metal sheets, their lower edges resting on angle irons 3 which are suspended by ropes 4, or their equivalents attached to the framing A. 47 represents nails driven into the superstructure a, 48 represents cables attached to nails 47 and to the inclined plates 1 and 2. The heavy portion of the base framing A represents a water tight tank, to be brimming full of water whenever the machine is being operated.
Stretching across the tank and resting on the sides thereof are two angles 13 (Figs. 1,
2 9 and 10), from each of these angles are suspended bolts 14 which support flat iron bars 8, or their equivalents, b'ent as shown in Fig. 1; to these bent bars are secured angles 6 by bolts 7. The bars 8 support cor: rugated plates 11, shaped like inverted Vs; inclined corrugated metal sheets 10, or their equivalents, rest on the angles 6 and their upper edges on the sides of the framing A; inclined corrugated metal sheets 12, or their equivalents, rest on the angles 6, their upper edges being secured by rivets, or other fasr tener to the angles 9. These corrugated plates and the angles 6 are placed lengthwise in the tank, and are equal in length.
5 represents iron channels, or anything that can be used for tracks, resting on the floor of the tank, and form tracks for the rollers 18 on the shafts 17, and thereby sup? port buckets 16 while passing through the tank.
20 represents a sprocket wheel mounted on shaft 17, and free to turn thereon. There is one sprocket wheel in each bucket, and two buckets on each shaft. The buckets 16 are duplicates, the sprocket wheels are duplicates, and the sprockets 21 are duplicates, and the spaces between each sprocket are equal. The surface of the sprocket immediately over the aperture 19 in the bucket bottom (see Fig. 5) and parallel thereto, is larger than the aperture, which prevents abrading material flowing through it whenever it is necessary to prevent it flowing.
The vertical broken lines 0 (Fig. 10) shows the space between the angles 6 to be greater than the width of the buckets 16 which provides a passage for the silt, on each side of the buckets, to the floor of the tank. The .abrading material is chiefly chilled iron globules; and their specific gravity being greater than the specific gravity of the silt, and being ejected together moves down the inclines more sluggishly, quietly slides from the angles and settles gently in a vertical manner, to the floor of the tank.
15 (Figs. 1, 9 and 10) are guides placed vertically over the tracks 5, and guide the buckets 16 in a true course. Each end of each shaft 17 is secured to an endless cable 22, (Figs. 1 and 2) and are by them carried around the machine.
23 (Figs. 1, 2, 3 and 8) represent a shaft unto which power may be transmitted through the medium of the pulley 27. On this shaft is secured duplicate sprocket wheels 25 provided with recesses 26 for receiving the rollers 18, of the shaft 17, thereby transmitting motion to the cables 22.
38 represents water supply pipes perforated with small outlets fitted with plugs 45 for regulating the supply of water. Turners 40, 41 encircle the supply pipes and are provided with shanks which, when turned downward as shown at 41 engages a sprocket 21 in a manner that turns the wheel on its axis, uncovers the aperture 19, and permits a flow of abrading material from the bucket until the wheel turns far enough to cover the aperture by another sprocket. The plug 45 immediately in front of a shank turned downward should be withdrawn to permit a flow of water. Turning the shank upward as shown at 40 to rest on the pipe, or other medium 39, the wheel moves forward without turning on its axis. Spacers 42 carried on pipe 38 and separating the turners are accurately gaged to turn a wheel just far enough to uncover an aperture and cover it with the next succeeding sprocket; the spacers maintain the turners in their respective position, protect the plugs from injury and provide free access to them. It is obvious that these several devices can readily be manipulated to secure a flow of water and abrading material to meet any requirement.
Immediately under each line of buckets 16 in the upper portion of the machine is a distributer 31 (see Fig. 8) its length being not less than the longest stone that can be operated on in the machine. The distributers are duplicates, each consisting of two corrugated plates, or their equivalents, and separated and secured at their upper extremities by a gas pipe, 33 or its equivalent. The lower extremities are riveted or otherwise secured to each other. A gas pipe 32 may be thrown in the distributer without each end. The pipes 33 serve as pivots for the distributers; therefore when the cranks are being operated, the distributers oscillate and deposit the water and abrading material, received from the buckets onto the inclined plates 1 and 2, vertically over the saws, and kerfs I) made by the saws in stone 8. The spacers 49 between the upper edges of the plates 1 must be equal to each other, so that each plate 1 will receive an equal amount of abrading material. The number of plates 1 must always equal the number of saws in operation, one plate for each saw. Plate 2 is used to prevent abrading material being thrown over the side of the stone. Tracks 46 supported by the superstructure a are provided for the rollers 18 (Figs. 1, 2 and 4).
