CIYIDE W. JONES, OF BLOOMINGTON, INDIANA.

STONE-GHANNELING MACHNE.

Application filed July 26, 1927. Serial No. 208,626.

The present invention relates to a stone channeling machine, and has for its prime object to provide a machine of this nature which is exceedingly simple in its construe tion, strong and durable, inexpensive to manufacture, thoroughly etlicient and reliable in use in operation, and otherwise well adapted to the purpose for which it is designed.

A further and -important object of the invention resides in the provision of a ma chine of this nature with a plurality of stone cutting tools grouped in a compact and convenient manner, and operated by a single shaft, and Iincorporates water cooling means for proper association with the tool.

With the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing Figure l is a side elevation of a machine embodying the features of my invention,

F ig. 2 is a vertical section therethrough,

Fig. 8 is a transverse horizontal section taken substantially on the line 3-3 of Fig. 2,

Fig. i is a horizontal transverse section taken substantially on the line lwll of Fig. 2, and

Fig. 5 is a top plan view of the machine.

Referring to the drawing in detail, it will be seen that the numeral 5 denotes an elongated casing of a flat-like formation, which has an enlarged portion 6 a slight distance from the upper end thereof. A. partition 7 entends longitudinally and centrally of the casing and divides the same into two compartments. This partition terminates at the enlarged portion 6.

A bearing block 9 yis mounted in the upper end of the casing, and in the present instance has four openings or bores l0, the number of these bores, is not of the essence of the invent-ion. Anti-friction bearings are provided lin the enlarged portion 6 as is shown at 1l.

A plurality of shafts l2 are `iournaled in the bores i and bearings l1 and entend longitudinally thru the two compartments of the casing, and are journaled in a bearing block structure 11i in the bottom of the casing. The lower ends of these shafts are provided with transverse openings l and longitudinally extending openings 16 which pass through the enlarged extremities 17.

he openings 16 provide sockets for receiving shrinks 18 of tools 19 which have bores 20 kto communicate at one end with the openings 16 and merge at their ends into lateral openings 20.

The bearing blocks lt are provided with inverted ii-shaped conduits or channels 2l, the lower extremities of which are adapted to communicate or register with the openings l5. rllhe pipes 22 lead upwardly from the tops of the T-shaped openings 2l and have elbows 23 at their upper ends with entensions through openings in the casing as Iindicated at 24. These pipes 22 will be connected with a suitable source of water.

A drive shaft 26 is engaged with one of the shafts l2, preferably one of the center shafts l2. All the shafts 12 at their upper ends, rave fixed thereto gears 27, which are in mesh with one another, so that the turning of the drive shaft 26 will cause the rotation of all the shafts l2, together, adjacent shafts turning in opposite directions. Thus thectools will rotate and adjacent tools will be rotating in opposite directions.

This unit is used for channeling and slotting stones, and can be widened out to contain any number of cutters. Suitable means may be used for forcing the apparatus against the stone. rThe cutter starts 0n top of the stone, and goes down through the depth desired to form the channel, and then may be raised up and moved over the width of the cutter and then it cuts down another slot, and thus a completed channel may be formed as may be desired.

It will be seen that the machine is compact and convenient ,in construction, and is strong and durable. rlhe present embodiment of the invention has been disclosed in detail merely by way of example, since in act-ual practice it attains the features of advantage enumera-ted as desirable lin the statement of the invention and the above description. l

lt is apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed, or sacrificing any of its advantages.

Having thus described my invention, what I claim as new lis l. An apparatus of the class described comprising a casing, a plurality of shafts journaled in the casing longitudinally thereof and in spaced relation to each other, the lower ends of the shafts projecting beyond the lower end of the casing, said lower ends of the shafts being formed with longitudinal bores merging into transverse openings inwardly of the casing, the lower portions of the bores forming sockets, tools having shanks fitting 4into the sockets, said shanks being hollow and merging into lateral openings exteriorly of the sockets, pipes extending longitudinally of the casing between the shafts, and means in the casing communicating each pipe with the transverse openings in the shafts next adjacent, so that each pipe casing being formed with bores having at their |inner ends transverse openings, tools having hollow Shanks projecting into the bores and iormed with openings eXterioi-ly of the bores, a pipe in the casing between the shafts, and means for communicating the pipe with the transverse openings of the shafts to form a common supply therefor.

ln testimony whereof I aliix my signature.
