STONE-POLISHING MACHINE.
SPECIFICATION formingpart of Letters Patent No. 420,203, dated January 28, 1890 Application filed October 25, 1889. Serial No. 328,199. (No model.)
To all whom it may concern:
Be it known that I, WILLlS A. LANE, acitizen of the United States, residing at Barre, 1n the county of Washington and State of Vermont, have invented new and useful Improvements 1n Stone-Polishing Machines, of
around their supporting-posts.
The said invention consists in the construction and combination of parts hereinafter set forth.
Reference ishad to the accompanying drawings, forming a part of this specification, in which letters of reference indicate corresponding parts in both the figures.
Figure l is a perspective-view of my improved polishing-machine as seen at work. Fig. 2 is a plan view of the belt T and gearmg.
A represents a column, B the swinging frames, 0 and D brackets, and E upright driving-shaft in rear of column A.
F is along upright screw in front of column A, and attached to step-bracketO at the bot- ;om and to bracket D at the top, as shown in G is a large gear, and H, I, andJ are smaller gears, as shown in Fig. 2.
K andL are pulleys, and M and N are tightening-pulleys.
O is a lever, P a handle attached to it, and Q a rock-shaft.
R is a pulley on the back shaft, and S a sliding box on back shaft that raises and lowers pulley R.
T is a belt; U, pulley on elbow; V, a shaft carrying pulleys WV W and U; Y, a belt running on pulleys W W and on pulleys X 'X, the latter on standard Z, to the lower end of which is attached, by a universal joint of any approved construction, the polishing head or wheel which is to be revolved on the face of a block or piece of granite or other material requiring a finish.
The hubs of arms B sliding up and down on column A are slotted, so as to be at all times adjusted properly to the shaft or col umn, thus preventing the hub from becoming loose on the shaft on account of loss from any wear of the parts. The hub B of arms 13 is secured by a spline or key B of Fig. 2
against turning on shaft A. On the driving shaft E is sliding box S, attached to the upper hub of frame 13, and slides up and down the back shaft the same as hub B slides up and down on column A, carrying with it the driving-pulley R, which is kept on a level The construction of my machine with iron brackets O and D, as shown in the drawings, enables it to swing the entire circle on the back shaftboxes, thus enabling a small-sized machine to cover every part of a large stone, leaving the back shaft to run free and easy.
The hubs of arms B slide up and down on column A to accommodate the machine to any thickness of stone to be polished and to raise the polishing-wheel for removing the stone when polished, and for inserting a new stone for polishing or for cleaning the machine when a different grinding or polishing material is used.
One great advantage I claim for my machine is the easy manner in which it may be raised or lowered by the application of power in the manner shown. F, the upright screw, passes through arms B, as shown. At the top of the arm is agear G,with ahub Z passing through the frame, with a collar Z fastened on under side to hold it in place. In the hub to the gear is a thread to match the thread on the screw. On one side of this gear is a small gear meshing into the first gear. On the other side are two small gears, as shown, set so as to reverse the motion. On either side is a small pulley attached to small gear, so placed as to clear the belt coming from pulley on back shaft to pulley on center shaft.
Attached to spindle that the pulleys and gears run on at top and bottomon either side are angle-irons running to outside of belt and holdingatightener,which,whe11 drawn against the belt, causes the inside pulleys to revolve, thus turning the small gear, which in turn runs the center gear which raises or lowers the arms on the screw-shaft F. The angleirons are connected together in line of gate by iron casting bwith joint. Connected with this joint is short lever 0, connected with rod Q running to under side of gate to short lever e connectedwith long lever 0, running to the elbow and bring to the gate by set-screw f. Connected to this lever at the center of elbowjoint is rod P, running to the front of the machine with a handle for operating. Pushing or pulling on rod P throws tighteners N or M against belt T, causing pulley K or L, with gears attached, to revolve in connection with gear G, which revolves on screw-shaft F for raising or lowering the machine.
g is a wire rope passing over a pulley at the bracket D, one end attached to aweight in column A and the other end attached. to frame B ne'ar pulley U, forming a counterbalance for the weight of frame 13.
sliding arms B B, attached to driving-shaft E by brackets O and D, belt T, in connection -with pulleys N and R, and sliding box S,
swinging on the bearings of shaft E, substantially as described and set forth.
2. In combination with the arms B, the screw F, attached to brackets O and D, 0p-
- erated by gears G, H, I, and J, with pulleys K and L, and tighteners M and N for raising and lowering the said arms, substantially as set forth.
3. The lever O,- handle P, and rock-shaft Q, arranged to operate tighteners hi and N on belt T, substantially as shown, and for the purposes described.
