STONE-SAWING- MACHINE.

Specification of Letters Patent.

Patented Oct. '13, 1908.

Application filed February 6, 1908. Serial No. 414,469..

To all whom it may concern:

Be 1t known that LARELI JONES, a citizen of the United States, and a resident of Oolitic, in the county of Lawrence and State of Indiana, have invented va new and Improved Stone-Sawing Machine, of which the following is a full, clear, and exact description.

The invention relates to stone-sawing machines using rotating drums and endless traveling wires passing over the drums and serving to cut the stone.

The obj ect of the invention is to provide a new and improved stone-sawing machine, arranged to permit of conveniently and quickly adjusting the wires in the desired position relative to the stone for cutting the latter into pieces of the desired width.

The invention consists in the construction and combination of parts to be fully described hereinafter and particularly set forth in the claims.

Reference -is to be hadto the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures, and in which Figure l is a side elevation of the improvement; Fig. 2 is a plan view of the same; Fig. 3 is an enlarged transverse section of the improvement on the line 3 8 of Fig. 4; Fig. 4 is a sectional side elevation of the same on the line 4-4 of Fig. 3 and Fig. 5 is an enlarged cross section of the improvement on the line 5-5 of Fig. 4.

The endless wires A, for cutting the stone B into pieces of suitable width, pass around drums C and C', having their shafts D and D journaled in suitable bearings arranged on the main frame E of the stone-sawing machine. On the shaft D is secured a pulley F, connected by a belt Gr with other machinery for imparting a rotary motion to the drum C, thus causing the wires A to travel, the lower runs-of the wiresy cutting the stone B, as indicated in Fics. l and 2.

The drums C and 3 are alike in construction Vand each is arranged in detail as follows: On the shaft D or D are secureda plurality of centers H, preferably made in sections fastened together by bolts H', H2, as plainly indicated in Fig. 4, and on the rims of said centers H, are longitudinallyextending rails I, preferably in the form of angle irons fastened to the rims of the centers H by bolts J, The rails I are spaced equidistant apart and are arranged in Va circle and engaged by bearings K formed on the rims K, preferably made in sections fastened together by bolts K2. By the arrangement described, any one of the rims K can be readily adjusted on the rails I in the direction of the axis of the drum, and after the desired adjustment is made, the rim is fastened in place on the rails I by clamping bolts L. By reference to Fig. 4, it will be noticed that the bolts L extend in slots formed by a pair of rails I, the said pairs of rails being arranged diametrically opposite each other and at right angles to the line of division of the rim K. Now, by the arrangement described, the operator on loosening the bolts L and K2, can conveniently shift the corresponding rim K on the rails I in the direction of the axis of the drum, so as to bring the corresponding wire A, which passes over the said rim K, into the desired position relative to the stone B. Each of the rims K is preferably provided in its peripheral face with grooves for the passage of the corresponding wire A.

From the foregoing it will be seen that the construction of each drum C or C is very simple and permits convenient and readyadjustment of the rims K carrying the wires A, so that the wires can be brought into the desired relation relative to the stone B to be sawed.

It is understood that by the improvement described the drums C and C can be made of large diameters without unduly increasing the weight of the drums; and large diameter drums are desirable to obtain as much frictional Contact between the .drums and wires as possible, to prevent the wires from slippingV on the drums.

In order to keep the wires taut, tightening sheaves N engage the upper runs of the wires adjacent to the driven drum C, as plainly indicated in Figs. l and Q; the tightening sheaves N being journaled in suitable bearings N held vertically and transversely adjustable on the frame E. Now by the use of the large diameter drums C, C and the tightening sheaves N, the wires A are prevented from slipping, and hence the efflciency of the sawing machine is increased.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

l. A drum for a sawino machine, comprising a shaft, a plurality of centers attached to the said shaft, rails ranging in the direction of the axis of the druni and secured to the peripheral faces of the said centers, sundry of the rails being arranged in pairs to forni a slot, the pairs being disposed dianietrically opposite each other, a riin inade in sections fastened together, and clamping bolts engaging the said pairs of rails and the rini to adjustably secure the latter on the rails.

2. A druni for a sawing machine, provided with longitudinal rails, sundry of the rails being arranged in pairs, to forni a slot, the l pairs being diainetrically opposite each other, a rini made 1n sections fastened together, and clamping bolts engaging the said i pairs of rails and the rini, to adjustably .se-

cure the latter on the rails.

A drinn for a sawing machine, provided With longitudinal grooves, a rim made in sections fastened together, and clamping bolts engaging the grooves, and the riln, to adjustably secure the latter on the drum.

In testimony whereof I have signed my naine to this specification in the presence olf two subscribing witnesses.

ARELI JONES.
