ROLL-JOURNAL.

SPECIFICATION forming part of Letters Patent No. 642,078, dated January 30, 1900.

Application filed June 10,1897. Serial No. 640,143. (No model) To all 10720722, it may concern.-

Be it known that I, OLIVER H. B'URGHAM, a resident of New Kensington, in the county of Westmorelaud and State of Pennsylvania, have invented a new and useful Improvement in RollJournals; and I do hereby declare the following to be afull, clear, and exact description thereof.

My invention relates to journal-boxes or brasses, as they are sometimes called, for use on all kinds of rolling-mills, such as sheet iron, tin-plate, copper, to.

The object of my invention is to provide a journal-box which will have a watercourse formed therein of such a character as will be effective in cooling the necks of the rolls and at the same time one so arranged as not to weaken the body of the box.

A further object of my invention is to provide a watercourse which may be readily exposed to view in case it is desired to remove any sediment which may collect therein or for any other purpose.

To these ends my invention comprises certain novel features, all of which will be fully hereinafter set forth and claimed.

To enable others skilled in the art to make and use my invention, I will describe the same more fully, referring to the accompanying drawings, in which- Figure l is a perspective View of my improved journal-box with the cover-plate removed. Fig. 2 is a section on line 2 2, Fig. 1. Fig. 3 is a section on the line 3 3, Fig. 1. Fig. 4: is a section on line A 4, Fig. 1; and Fig. 5 is a perspective view of the cover-plate on a smaller scale.

Like letters of reference indicate like parts in each view.

In the drawings the letter a designates a journal-box formed of brass, Babbitt metal, bronze, or other metal. The journal-box a has the bearing-face 1), adapted to engage the neck of the roll. (Not shown.) The waterpassage 0 is formed in the opposite or rear face of the journal-box, and said water-passage is composed of the inlet-passage c, which extends along one end of the box and communicates at its inner end with the crosspassage 0, said cross-passage communicating This passage 0 com muwith the passage 0 nicates with a second cross-passage 0 the latter in turn communicating with the crosspassage 0 by the short passage The crosspassage 0 comm uuicates with the outlet-pas- 5 5 sage c. In this manner a tortuous Waterpassage is obtained, which is cast in the metal on its rear face, and in casting such a waterpassage the walls or partitions d, d, and d are formed, which separate the several passages which compose the tortuous water-passage. An inlet-port e admits water or other cooling fluid to the passage 0 and an outlet-portf permits of the escape of the water after it has done its work. Pipes may be connected up to said inlet and outlet ports for conveying the Water to and from the box.

In order to expose as much as possible of the rear face of the box to the cooling action of the water, it is desirable to make the crosspassages c, 0 and c as wide as convenient; but it is preferable to make the end passages 0, c and a narrower and deeper in order to obtain longer cross passages. Accordingly the increase in depth in the end passages compensates for the increased width of the cross passages. As the cross passages are not so deep as the end passages, there is a slight offset, as at h, where said passages communicate, and these offsets are curved or inclined, so that abrupt shoulders are avoided, which are apt to collect sediment and clog up the passages.

A cover-plate t, of metal or other suitable material, is adapted to be secured to the rear face of the journal-box to close the water-passage O. This plate is secured to the box by means of screws 75, entering suitable openings formed for them in said box. To make a water-tight joint between the plate 2' and the box, a gasket m, of rubber or other suitable material, is interposed. This gasket not only engages the outer edges of the water-passage, but has the inwardly-projecting strips m. adapted to engage the walls or partitions d cl 01 When the plate is screwed down tightly on the box, the gasket forms a water-tight joint which will prevent leakage not only around the outer edges of the water-passage, but from one cross-passage to another, so that all the water is compelled to follow the tortuous watercourse laid out for it.

When my improved journal-box is in use, the water or cooling fluid is admitted by the inlet-port e to the passage 0, whence it passes into the cross-passage c and thence through the several passages until it escapes through the outlet-port f. A constant circulation is thus maintained throughout the tortuous water-passage, acting to cool the neck of the rolls and prevent the rapid wearing away or cutting of said necks. The cover-plate prevents the liquid from leaking and dropping onto the necks of the rolls, while at the same time by simply removing said plate the water-passage is exposed to View for purposes of cleaning, the. The body of the box is not weakened by the water passage, as it is formed in the rear face of the box and not within the body thereof, as in most journalboxes of this kind.

The advantage arising from the removable cover-plate in connection with the cleaning of the passages is very important, as in the ordinary roll-housin g the Wateris liable to carry sedimentary matters which would clog or fill the passages and to that extent render the journal-boxinoperative. \Vhile therefore the tortuous passage is preserved and the water compelled to pass through the same, the passage can be very quickly cleaned by the mere removal of a few screws. I am aware of the fact that journal-boxes have been made having curved rear faces with tortuous passages formed in the same, such boxes fitting against the ordinary holding or sustaining blocks, which close the passage. In the present case the tightness of the water-joint does not depend upon the fit of any such block, but is positively obtained by the cover-plate and its gasket, while all the advantages of cleaning such passages when necessary are obtained.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A cooling-brass for roll-necks having a flat outer face and having inlet and outlet passages communicating with a tortuous water-passage formed in-the outer face of said brass, and a fiat cover-plate secured to the upper face of said brass, substantially as set forth.

2. A cooling-brass for roll-necks having a fiat outer face, an entrance-passage formed along one side of the outer face of said brass and an outlet-passage at the opposite side of said brass, cross-Walls projecting from opposite sides and forming cross-passages communicatin g with said side passages, the entrance and outlet passages being deeper and narrower than said cross-passages, and a flat cover-plate secured to the outer face of said brass, substantially as set forth.

3. A cooling-brass for roll-necks having a flat outer face, an entrance-passage formed along one side of the outer face of said brass and an outlet-passage at the opposite side of said brass, cross-walls projecting from opposite sides and forming cross-passages communicating with said side passages, the offset at the juncture of said side and cross passages being inclined, and a fiat cover-plate secured to the outer face of said brass, substantially as set forth.

4:. A cooling-brass for roll-necks having a fiat outer face, an entrance-passage formed along one side of the outer face of said brass and an outlet-passage at the opposite side of said brass, cross-walls projecting from opposite sides and forming cross-passages communicating with said side passages, and a gasket adapted to rest upon the outer edges of said box and on said cross-walls, and a fiat cover-plate secured to said box, substantially as set forth.

In testimony whereof I, the said OLIVER H. BURGHAM, have hereunto set my hand.
