STONE, GRANITE, OR MARBLE CUTTING MACHINERY.

SPECIFICATION forming part of Letters Patent No. 725,301, dated April 14, 1903.

I Application filed October 7, 1902.1Serial No. 126,332. (No model.) I

To all whom it may concern: U

Be it known that I, SAMUEL WALTER VINT, a subject of the King of Great'Brit-ain and Ireland, whose postal address is Ash Croft,

Underclifie, in the city of Bradford, England,

have invented certain new and useful Improvements in Stone, Granite, or Marble Outting Machinery, of which the following visa,

specification.

This invention relates to certainimprovements in stone, granite, and marble'cutti'ng machinery, and has for its object the automatic feed and more even supply of 'sand'and able, and the faces of the cuts'are smooth in. some places and rough in others. The water suitablemesh. ThelathsMaresuspendedfrom and sand once used is wasted.

In describing my invention in detail reference is made to the accompanying sheet of drawings, similar letters indicating similar parts where they appear, in which- Figure 1 represents a plan of a portion of a stone-sawing machine with my1improvechine I attach in any convenient manner three cross-beams B, B, and B Mounted on the upper side of -the beam B and about the center of the same is a vertical support or shaft C, at the. top of which is mounted a circular or other convenient shaped vessel D, the whole beingfree to revolve. To the upper portion of the vessel D is attached a grooved pulleyE of suitable diameter. The vessel, pulley, and shaft may be supported by a bracket or the like E near the top, as may be found most convenient, in order to insure rigidity. Leading from the vessel D in an outward and downward direction are one or more pipes F r of convenient size. Mounted on the before- -.mentioned beamsB, B, and B and below the ends of the pipesF is what may be termed a wheel-rim? G, which is of about the same :diameter as the circle described by the pipes when in motion. The Wheel-rim G on its upper surface-is divided into small hoppers H forits-entire surface, and the sides of the wheelrim G are continued upward, forming one hopper for the total circumference of the same, as shown in Figs. 3 and 4. In the center of each hopper and at the bottom of the ,same is bored a hole J, leading from whichis a'flexible tube K of suitable length or other convenient means for-conducting the water and sand or the like on to the saw-gates, which may be placed in the required position over the sawgates and held in position by laths M, suspended horizontally over the stone, the said laths having bent wires or staples N on the upper side, through which the tubes K may be passed andbe .held in position. I

.In place of the laths M and the bent Wires or staples N, I may use ordinary wire-netting of the'beam's B B by rods or the like 0, hinged at P. The said laths M may, if required, be 'driven in any convenient manner and given a backward-and-forward motion about the length ofthe stroke of the machine. On the saws Lbeing put into operation the pulley E, attached to' the before-mentioned vessel D, whicl1,.with the"pipes F, revolves, may be driven in any convenient manner. The water and sand or the like passes through a pipe Q, through an orificeR in the pulley E to the vessel D, and down through the pipes F to ,the hoppersI-I. Fromthere it is conducted to the saw-gatesby the flexible tubes K and a constant even supply maintained. The material used after being fed to the saw-gates is collected below in any convenient manner and taken away by a drain to a sump and from there is elevated by an ordinary elevator and delivered through the pipe Q to the vessel, and so on to the saw-gates again.

Under the before-mentioned process the faces of the stone out are uniformly smooth. The saw-blades last longer, as'they do not come in contact with the stone sawed, the sand or the like being always between the cutting edge of the saw-blade and the stone. I in the manner and for the purpose as herein- :0 An even supply of Water is given to the Whole before described and shown. length of each saw-blade. In witness whereof I have hereunto set my Vhat I claim as my invention ishand in the presence of two witnesses. 5 11 stone, granite, and marble cutting machinery, a vertical support or shaft 0, vessel l SAMUEL VINT' D, pipes F, wheel-rim G, divided into hoppers Witnesses: I-I, flexible tubes K, laths M, with means for' CLIVE WAUGH, holding the tubes K in position, substantially JOSEPH P. KIRBY.
