ROLL-COOLING. missus.
Specification ofL-ctters Patent.
Patented May 1920.
Application filed September 6,1918. Serial N0. %,857'.
1 0 all tvlwm'itm'ay concern:
Be it known that I, TIioMAs D. Home, a citizen I of the United States, residin at Duluth, in the county of St Louis and .btate of Minnesota, have invented certain new and useful Improve'mcnts'in RolLCooling Means, of which. the following is a specificm tion.
. This invention relates to the metal rolling art, and more particularly to means for maintaining the metal working rolls in a relatively cool condition.
One object of the invention is to increase the life oil? metal working rolls'bycooling 15 same in an improved manner.
Another object of my invention is to provide simple and eflicient means for cooling metal working rolls in a mannerto meet the requirements for successful commercial operation. 7
These and other objects are nccomplished by the arrangement disclosed on the accompanying sheet of drawings, in which- Figure lis a fragmentary front elevation of metal working rolls equipped with my cooling means, and
Fig 2 is a sectional view of the same taken in the plane of line2-2 of Fig. 1
It is awell established fact that unless metal working rolls are ma ntained reasonably coolythe same wear and abrade rapidly.-
This is particularly true of rolls which are provided with collars which form passes, thecorners of the .collars. being subjected tmeXtreme temperatures and severe work ing conditions. It is common practice to supply water-in ageneral way to these rolls for maintainingthe same cooh but in spite of this fact,- the collars f rolls having passes wear and abraderapir' ly. This is due pr1 marily-to the fact that these collar portions have not heenlmamtamed sul'liciently cool.
in good operating conditions, 7
and in addition thereto direct definite supply of water directly tothe collars, and
particularly to the corners thereofl for maintaining the same in a relatively cool" condition.
. By'referring to 'the figures of the "drawings, it will be noted that I have'shown a plurality of" associated rolls 10, having passes 11- formed by collars liZ distributed along-the length of the rolls. Overlying these rolls is a pipe 13 for conveying water, or any other suitable cooling medium, said pipe being provided along the bottom thereof with'aplurality of apertures 1a throughwhich the cooling medium, such as water, may passan'd be directed against the rolls 4 10 throughout the length thereof. As stated above, the collars 12, and particularly the corners thereof are subjected to. extreme conditions of temperature and wea'r. To compensate for these extreme conditions, and for maintaining the collars in a relatively coolcondition I have providedmeans for. directing "an additional and a definite supply of water to the collars 12, and particularly the corners 15 thereof. This means for directing'the cooling water takes the form of nipples 16, which are connected to the pipe 113', andwhich are adjustable for directing the flow oi? water to the corners. 15 of the collars 12. I have found that thelife of rolls is very materially increased, in fact,
asmu'chas 20 per cent.,' by applying waterin this manner. It is my intention to cover all modifications" of my invention falling within the spirit" and scope of the following claim.
What I claim is: In a coolingsystem for metal working rolls having collars, the l combination of means whereby. a cooling medium may be supplied along the length of-said rolls, and ineans wherebyan additional. supplyo'f said cooling medium may be supplied to'tlie collarson said rolls.
