COOLING APPARATUS FOR PAINT-MILLS.

SPECIFICATION forming part of Letters Patent No. 295,626, dated March 25, 1884.

Application filed October 8, 1883. (No model.)

To aZZ whom, it may concern Be it known that we, L. EUGENE FULLER and JosEPH H. MAOAULEY, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Cooling Apparatus for Paint-M ills, of which the following is a specification, to wit:

This invention relates to an improvement in cooling apparatus for paint-mills and it con sists in the peculiar construction and arrangement of the same, whereby thewater for cooling the upper stone is passed directly to the lower stone and cools it before being carried off by the waste-pipe, while at the same time the proper adjustment of the stones with reference to each other is not impeded, substantially as will be hereinafter more fully described, andpointed out in the claims.

In order to enable others skilled in the art to which our invention appertains to make and use the same, we will now proceed to describe its construction and operation, referring ing-shaft, A",

to the accompanying drawings, in which- Figurel is a central vertical section of the two stones and their cases and the main connecting portions of a paint-mill. Fig. 2 is a plan view of the upper case; Fig. 3, a similar view of the lower case with the stone removed. Fig. 4 is a vertical section of the pipes con necting the upper and lower cases. Fig. 5 re presents the coupling at the lower end of these pipes; and Fig. 6 is aside elevationof apaintmill, showing the relative positions of differentparts of our invention.

.A represents the main frame of a paint-mill, provided withthe usual mixer, A, and a drivgiving motion in the usual way by suitable gearing both to the mixer and to the lower stone of the mill.

Upon the main frame, in a suitable position with reference to the other parts, is supported the case B, ofcylindrical form, in which is secured the upper or stationary stone, B, which does not quite fill the case, but a small space is left between the top and sides of the stone Below the upper stationary stone, B, is arranged the runningstone 0, also set in a case, 0, which incloses the stone, both inside and out, with a space, 0, for the circulation of water, as already described. The cent-er of the case 0 forms a covered chamber, C ,'which rises through the center of the stone 0, as fully represented in Fig. 1.

Formed with or attached to the bottom of the case 0 is the supporting-spindle D, having its upper end formed hollow for a short distance, and opening into the water-chamber 0 through a pipe, D, extending up through this chamber, and having its upper end perforated, as seen at d. The hollow spindle is also provided with a series of horizontal tubes,d, passing through the water-chamber and opening into the space 0 under the stoneG.

Below the case G in the main frame of the mill is arranged a plate, E, through which the spindle D passes, which plate is formed with a cored passage, 6, the outer end of which may be connected in any suitable manner with a waste-pipe for carrying off the water, and its inner end terminates in a circular chamber, e, which is in communication with the hollow spindle D by means of a hole, d in its side.

To allow of the vertical adjustment of the lower stone and its case, it is necessary to make a sliding connection between the pipes F F, and we accomplish this in the following manner, as clearly represented in Fig. 4:: The upper end of the short section F is formed with a flange, f, and is free to move in a cylindrical chamber, f, in the union or coupling F. This coupling is attached to the end of the pipe F by a screw-plug, f and to its lower end is secured a stuffing-box, f surrounding the section F and is formed with an extensiom'f, which extends downward around the short pipe-section a short distance, and protects it from contact with the paint or varnish, which might prevent its free movement in the coup- 1ing. The lower end of the section F is provided with a socket, G, formed with interior inclined sockets, g g, and the top of the waterchamber 0 is provided with anipple, G, havmg two wedge-shaped projections, which enter the socket G, and are firmly locked there in when the nipple is turned by being forced up in the sockets g g, as will be understood by reference to Figs. at and 5. Ihe spindle of the running-stone is stepped in a lever, H, having an adjusting-screw, H, as shown in Fig. 6, by which means this stone is raised or lowered in the ordinary way.

In operation, the water is forced into the upper case under pressure, and, passing entirely around it, is passed into the chamber}? through the pipes F F and-their adjustable coupling. After circulating around the lower stone, 0, the water is passed off through the pipes d, hollow spindle D, and cored plate E. During this operation the chamber C becomes filled, and the water entering here has time to cool before it is forced around the lower stone and passed off, as described.

While we prefer to use water under pressure, it may also be used without the pressure,

and in that case the ends of the tubes d are plugged up through openings in the side of the case made for that purpose, and the water exhausted from the chamber 0 through the overflow-pipe in the upper end of the hollow spindle. It will be observed that by this arrangement the water used for cooling the upper stone is passed to the lower one before exhausting, thus saving a great amount, and at the same time the proper relative adjustment of the stones and the removal of the lower one for repairs, 850., is not interfered with, the sliding union allowing the section F to have a vertical as well as a revolving motion, and the flange preventing its accidentalwithdrawal through the packing-box.

Having thus fully described our invention, what we claim as new,,and desire to secure by Letters Patent, is-

1. In a paint-mill, the running-stone 0, casing 0, having a circulating-space around the stone, and the hollow spindle D, in combination with the plate E, through which the spindle passes, formed with the cored passage 6 and chamber 6, substantially as, shown and described.

2. In a paint-mill, the runningstone (l and its case O,. formed with a circulating-space around the stone, and with the receptacle 0*, in combination with the hollow spindle D, pipes d, and extension D, formed with perforations d, substantially as and for the purpose set forth.

3. In a paint-mill, the stationary stone B, its case B, having a circulating-space, b, and the partition I)", the supply-pipe F, connected on one side of said partition, and the pipe F upon the other, the coupling F and section F in combination with the coupling G, chamber C case 0, stone 0, and hollow spindle D, all constructed and arranged to operate substantiallyas and for the purpose set forth.

In testimony whereof we have hereunto set our hands in the presence of two witnesses.

In presence of- A. O. J AMES, FRANK E. REED.
