TINGLEY, AND A. H. TINGLEY. l
MACHINE Eon sAWING MARBLE.
Specification of Letters Patent No. 7,201, dated March 19, 1850.
Capable of Being Reduced Thereby; and I do hereby declare that the same is fully described and represented in the following specification and accompanying drawings, letters, figures, and references thereof.
Of the said drawings Figure l, denotes a` Fig. 2
top view of my improved machine. is a front or side elevation of it.
In the same A, represents a gang or series` of saws, fixed 1n a horizontal frame B, sus-` pended over a block of marble C, by four chains D, E, F, Gr, which respectively depend fromand pass over four pulleys or sheaves H, I, K, L, arranged and fixed on two horizontal shafts M, N, which extend across and are supported on the tops of a suitable frame O. The chains extend to and are wound upon two windlasses P, Q, aiiixed upon a horizontal cross shaft R, which is arranged on `the top of the frame O, and midway between the two 'shafts M, N. Each of the said windlasses has the two chains on the same side of the frame wound upon it, and so wound on it that while the revolution of the windlass in one direction may simultaneously wind the two chains on it, its revolution in the opposite may simultaneously unwind them from it; the first operation serving to raise the gang of saws, and the lasts operation serving to depress or lower them.
On one end of the shaft R, is a sprocket wheel S. About the periphery an endless `chain T, extends, and also around another and smaller sprocket wheel U, disposed as `seen in Figs. 2 and 3, the latter of which short horizontal shaft 7c on or near the innerm end of which a ratchet wheel Z, is fixed, the whole being arranged and applied together as seen in the drawings. An arm m, movable on the shaft 7c, has a small impelling click or pawljointed to its upper end and made to act against the teeth of the ratchet wheel. The upper end of the arm is also jointed to one end of a connecting rod n, which at its opposite end is connected with an arm or slotted plate o, shaped and made to project from a horizontal rocker shaft p, as seen in Figs. l, 2, and 5; the latter ligure being made to represent a side view of the arm and its crank connecv tion with the shaft.
A crank or bent piece of metal g, isfastened to the end of the shaftp, by means of a screw nut r, `as seen in Fig. 5; the horizontal part of the crank g, being carried below the line Ofthe axis of the shaft produced. To the outer end of the crank g, the slotted plate 0, is affixed, and extends up therefrom as seen in Fig. 5. A slot s, is made through this plate for the reception of a screw t, which passes through it, and has its head bearing 4against the plate on `each side of the slot. A section of the said screw, the slotted plate, the connecting rod n, and the screw nut a, is given in Fig. 6, which is a horizontal section `of the said parts taken in line of the axis of the screw. It will be seen that two cylindrical washers o, w, are placed on the screw. viz, o, is about the diameter of the head of `the screw. The other, viz, fw, is somewhat less in diameter, and is a little larger than the width of that part of the connecting rod placed on it.` When the screw nut u, is screwed down against the washer fw, it will cause the screw t, to be fixed to the plate 0, in any position in which the said screw may happen to be placed, or in other words either in line of the axis of the shaft p, or at any distance therefrom within the limits of the length of the slot of the plate.
From the shaft p, a crank extends, and is jointed to the lower end of a connect- Une of them` i ing rod y, which, at its opposite or upper end, is jointed to a crank a, which extends from another horizontal shaft a, which is the driving shaft of the machine; there being a fast and loose pulley, and a iiy wheel fixed on it, b', being the loose pulley, c', the fast one, and d, the fly wheel, all as seen in Fig. l, the said shaft being supported by a framework c. vThe driving belt which puts themachinery in operation is carried around the fast pulley.
The rocker shaft 0 has two arms or cranks f g extended in opposite directions from its middle part. A pitman or connecting rod L is jointed at one end to one or the other of these arms, and at the other end of it, it is also jointed to the saw frame B. The object of the two cranks or arms f g, extended in opposite directions above and below the shaft p, is to enable the connecting rod or pitman of the saw frame to be applied either to that one which is above t-he shaft 79, when the saw frame is above the level thereof, or the other of them, when the said frame s below the said level. Thus the power which impels the saws may be made to operate without a material loss which might accrue were the connecting rod to operate under too much inclination, which it would otherwise attain when the saws approached the lower part of \the block of stone. The movement of the plate 0, is an oscillating one created by that of the rocker `shaft to which it is connected. Such moveby simply increasing or diminishing the distance of the axis of the screw nut u, from that of the shaft 79, produced.
I would remark that the gear wheel e, be-
Vforementioned is made to run loosely on its shaft, and is connected or locked to it by means of a ratchet wheel z", fixed to the shaft, and a spring click c, fixed to the wheel e. If the click 7c', is lifted out of action with the ratchet wheel, the shaft of the wheel e, is left free to be turned by a crank Z. By laying hold of the said crank and turning the shaft d, it will readily be seen that the saw frame may be either elevated or depressed, at a much -faster or quicker rate than it can be by the mechanism before described.
Horizontally and transversely over the block of stone, is a water tube m', which is supported in position by two tubes n', o', which extend down from a hollow rocker And the extent of such depression in any given time may be regulated shaft p, to one end of which a hose is attached and made by suitable means to lead water into the shaft, from whence it is made to flow down the tubes n, 0, and into the distributing tube m', the lower partV of which is punctured with numerous ne holes so placed as to allow the water to fall down upon the saws while they are in operation. A reciprocating movement of the water distributor is given to it by means of a connecting rod p2 and a pulley g the rod 75 being jointed both to the pulley and one of the upright tubes of theV distributor, the said movement being effected when the pulley is put in revolution, the said pulley be-A ing rotated by means of an endless band r', 80 which is made to operate around it and a pulley s, fixed on the driving shaft. This movement of the water distributor being back and forth over the stone and in a direction from end to end of it, showers the water upon or over its surface in an equable regular manner, whereby the saws are made to cut or operate to much better advantage than they do when water is applied to them by any of the modes ordinarily adopted.
What I claim as my invention is as followsthat is to say, I claiml. The combination of mechanism applied to the sprocket wheels, endless chain windlasses and suspension chains of the saw frame; the said combination being for the purpose of gradually lowering the gang of saws in the proportion required, as the sawing process progresses. This combination consists of the train of mechanism which is applied to the lower sprocket wheel shaft, or axle b, and the driving shaft, and intervenes between the two, and is actuated by the revolutions of the driving shaft said train of mechanism consistingof the tooth gear a, pinion c, gear wheel e, endless screw f, beveled wheel 71 pinion z', and ratchet wheel Z, together with the pawl arm m, connecting rod n, slotted plate 0, rocker shaft p, crank Q, screw t, screw nut u, washers fv, lw, cranks and a, and connecting rod fz, as above specified. Not meaning to claim as any part of the same the crank Z, click c, and ratchet wheel z, except in their combination therewith, and for the purpose of enabling a person to raise or lower the gang/ of saws by applying his hand to the crank;
'it being understood that when these last contrivances are not used, the wheel e, must be firmly xed to its axis, and not placed loosely thereon as it is when such contrivances are employed.
2. I also claim, the employment of the two arms j, g, extended in opposite directions above and below their rocker shaft, p, and used in the manner and -for the purpose as specied.
3. I also claim, the vibratory tubular Watering apparatus m', n', o', p and my signature this first day of October A. D. mechanism combined with it said mecha- 1849. nism consisting of connecting rod p2, pulley g endless band 7 and pulley s', for giving 5 to it .a vreciprocating movement over the Witnesses:
gang of saws and stone as specied. WILLARD CHASE,
In testimony whereof I have hereto set SAML. W. PECKHAM.
