ROLLS FOR MAKING TERNE PLATES.

SPECIFICATION forming part of Letters Patent No. 623,389, dated April 18, 1899. Application filed October 21, 1898. Serial No. 694,242. (No model.)

T0 at whom it; may concern:

Be it known that I, THOMAS WILLIAMS, a citizen of the United States of America, residing at Cannonsburg, in the county of l/Vashington and State of Pennsylvania, have invented certain new and useful Improvements in Rolls for Making'lerne Plates, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to certain new and useful improvements in rolls for making terne plates.

The object of my invention is to provide a series of rolls which are adapted to be arrangedwithin the pot containing the alloy and oil or grease, having their periphery grooved, and owing to said grooves formed on'the rolls the alloy is evenly distributed upon the terne-plate while the same is passing therethrough.

A further object of my invention is to provide a suitable regulating means which is suitably adapted to operate against the rolls to allow the coating of the alloy upon the plates to be made of different thicknesses. The difficulty heretofore in the man ufactured terne plates While passing through the series of rolls was that the plate would be coated in an uneven manner, thereby making the same thicker at different parts and also rough. I find that by grooving the rollers as shown the plate as it leaves the rolls will be of uniform thickness, thereby obviating the heretofore-mentioned defects which occur in the manufacture of the terne-plate.

My invention therefore consists in providing a series of rolls with suitable grooves, the arrangement of which will be herein after more fully described.

Briefly described, my invention consists in I the arrangement of an upper and lower series of rolls in pairs having suitable grooves formed on theirperiphery, these grooves being continuous and arranged in opposite directions to the indentations of the adjacent rolls, and suitable regulating means operating against the rolls for extending or closing the same against the plates as they pass therethrough.

My invention finally consists in the novel arrangement of parts hereinafter more specifical ly described, and particularly pointed out in the claims hereunto appended.

In describing the invention in detail referonce is had to the accompanying drawings, forming a part of this specification, wherein like numerals and letters of reference indicate corresponding parts throughout the several views thereof, and in which- Figure 1 is a longitudinal sectional view of the common form of apparatus used for coating terne plates, showing the position of my improved rolls and the regulating means therefor. Fig. 2 is a top plan View of the upper rolls. Fig. 8 is a top plan view of a portion of the lower rolls. Fig. 4 is'a longitudinal sectional view of a portion of one of the lower rolls. Fig. 5 is a cross-sectional view of one of the lower rolls.

Referring now to the drawings by reference-numerals and which for illustration is shown the ordinary apparatus used for the coating of terne plates, 1 indicates the pot containing the alloy of lead or tin and beneath which is arranged. the fire-chamber 2.

3 indicates the passage formed by arranging within the pot a pair of curved plates 4 and 5, which are adapted to coincide with the outlet-opening 6, formed in one side of the pot 1. The plates 4 and 5 are suitably apertured to allow the alloy to enter the passage 3 and are secured to the walls of the pot by any suitable means, as at 7.

Connected to the pot 1 by means of the passage 8 is a pot 9, which contains the alloy A and the grease or oil B. The arrangement of this oil and alloy is the same as in ordinary devices of this character. This passage 8 is formed by a pipe 10, which is cast integral with the pots 1 and 9, as at 10 10. The pot 9 is provided with an ordinary fire-chamber 11, arranged beneath the same. Arranged within pot 9 are a pair of curved plates 12 and 14. These plates form a passage 15, and they are similar in construction to the curved plates 4 and 5, being also perforated to allow the alloy and grease or oil to enter the passage 15. I arrange within the pot 9, on each side thereof, a pair of housings 16. (Only one shown.) These housings are adapted for supporting the rolls, regulating mechanism therefor, and curved plates 12 and 14. They are downward within the pot,'as shown.

also removably mounted within the pot 9 and are cut away at their top to allow the operation of the regulating-springs, which will be hereinafter more fully described. Suitably journaled in any manner in the housings 16 are the upper rolls 17 and the lower rolls 18, which are grooved, as at 19, in the upper rolls and at 20 in the lower rolls. It will be observed thatlthese grooves are continuous, and they are arranged in opposite directions, as shown. I find that by grooving these rolls the upper series approximately to a scale twelve to an inch and the lower ones approximately to a-scale of seven to an inch the operation of the rolls upon the terne-plate while it is passing between the same will give the uniform surface thereto.

For regulating the rolls to increase or decrease the coating of alloy of the terne plates while passing therethroughIsecure to one side of the rolls a pair of elongated steel springs 20 20 which are bent at right angles and extend The spring 20 is pivoted, as at 24, and the one end thereof is apertured and operates on a screwthreaded rod 22, the downward movement thereof being arrested by means of the nut 23, operating on the rod 22. The spring 20 is pivoted, as at 24, and the one end thereof is apertured and operates on the screw-threaded rod 25, the downward movement thereof being arrested by the nut 26 operating on the rod 25. It is readily apparent on raising the end of the springs the rolls will be brought together and a thinner coating of alloy will remain on the plate when the same has passed therethrough than if the rolls were forced farther apart by the lower end of the springs. The rolls are so arranged in the pot that the lower pair is in the oil or grease and about six inches above the alloy, while the upper pair is in a portion of the grease or oil and about twelve inches above the alloy.

By the helical grooves, which are continuous and which are formed on the periphery of the rolls, and by the arrangement of the grooves on the upper rolls being, as heretofore stated, about almost double the number to the inch as of the lower rolls the operation of the same upon the plate will do away with of my improved grooved rolls that the defects have been caused by the smoothness of the rolls.

Suitable operating mechanism is employed for operating the rolls, which it is not deemed necessary to illustrate or describe.

It will be noted that various changes may be made in the details of construction without departing from the general spirit of my invention.

Having thus fully described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

1. In an apparatus for making terne-plate, an upper and lower pair of helically-grooved rolls, the groove of the upper pair of rolls being of a less pitch than the groove of the lower pair, and means for regulating the said rolls whereby diiferent thicknesses of coating may be applied to plates, substantially as set forth.

2. In an apparatus for making terne-plate a pair of upper rolls having a continuous helical groove formed on the periphery thereof at the scale approximately twelve to an inch, a pair of lower rolls having a continuous helical groove formed on their periphery at the scale approximately seven to an inch, and means for regulating the said rolls whereby different thicknesses of coating may be applied to plates, substantially as herein shown and described.

In testimony whereof I affix my signature in the presence of two witnesses.

THOMAS WILLIAMS.
