SPECIFICATION forming part of Letters Patent No. 483,926, dated October 4, 1892- Application filed March 8, 1892. Serial ll'o. 424,166- (No model.)

To 60% whom, it may concern:

Be it known that'l, GRIFFITH W. JONES, of Reading, in the county of Berks andState of Pennsylvania, have invented certain new and useful Improvements in Rolling-Mills; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in rolling-mills; and it consists in certain novel features of'construction and in the combination and arrangement of parts, which will be fully described hereinafter, and more particularly referred to in the claim.

The object of my invention is to construct an improved mill for the rolling and cleaning of black tin and terne plates and light sheetiron in which the same is subjected to the direct action of a series of rolls, being carried from one series to the nextadjacent rolls by means of an endless apron formed of drivechains.

Referring to the accompanying drawings, Figure 1 is a side elevation of my improved mill. Fig. 2 is a plan view of the same. Fig. 3 is a sectional ,view of the coupling-bar.

A represents the housing for the initial rolls B, C, D, and E, the latter two being the upper rolls of the adjacent pairs, as shown in Fig. 1. These rolls are j ournaled in vertical openings formed in the housings A, and thus their relative positions never vary, while at the same time the housings are formed in the most cheap and simple manner.

F represents the outwardly-extending spindles, which are connected at their inner ends to the extended necks of the rolls B O by means of the longitudinally-movable collars G.

H represent pinions, which are j ournaled in suitable bearings in line with the spindles F, to the outer ends of which they are connected by means of the collars I. Beneath the said pinions is j ournaled the idler J, by which they are engaged, and thus made to revolve in the same direction, communicating a relative motion to the rolls B 0 through the connectingspindle and collars, above described. The driving power maybe applied to either of the said extended spindles, and through them it is communicated to the several rotating parts of the mill. v

Kand L represent thehousings which support the auxiliary or finishing rolls M M and N N. Secured to the ends of the rolls M N are the bevel-pinions O, which engage the bevel-pinions P on the horizontal, shaft Q, which extends parallel with the mill. Secured to the end of this shaft is the gear R, which engages the bevel-gear R on the end of the roll 0, and by means of this latter set of pinions the said horizontal shaft is driven, which in turn drives the rolls M N, as will be readily understood by referring to Fig. 2.

Journaled in the adjacent sides of the respective housings and in a-line with the top surfaces of the lower rolls are the shafts S, carrying the sprocket-wheels S, and the adj acent shafts S are connected by the sprocketchains T, and by this means an endless apron or conveyor is formed between the several sets of rolls for the purpose of conveying the metal plates being operated upon.

The shafts S receive their power from the roll B through the medium of the drive-chain U. Journaled in the several housings immediately above the shafts S are the false rollers V for the purpose of preventing the metallic plates from crimping or turning up after leaving the rolls. To accomplish this result, between the rolls D E a stationary depending false guide W is provided, as shown by dotted lines in Fig. 1.

Between the housings K L is arranged a suitable support and bearing X for the rotary metallic brush Y immediately above the endless apron T. This brush derives its motion from a counter-shaft Z, which may be driven in any suitable manner from the source of power. The upper rolls of the several pairs are adjusted vertically within their respective housings by the screws 2 in the usual manner. Supporting-plates 3 are provided for guiding the metal being operated upon between the rolls.

In operation the plates are introduced between the initial pressure-rolls D B and E O, by which they are flattened or rolled to the desired degree, and emerging from these rolls they are conveyed to the rolls M M and N N last-named sets of rolls the plates are sub jected to the action of the rotary brush Y, which being revolved at a high rate of speed efiectually removes the scales and other for eign matter which may have accumulated on the plates. After this treatment the plates emerge from the discharge end of the mill perfectly clean and bright. The initial rolls being quite close together the plates are subjected to the action of each set at the same time. The metal while being subjected to this first reducing process is thick and bulky and the stretching of the plates by being subjected to the action of both sets of rolls at the same time cannot injure them; but when they leave these rolls it is desirable that they be entirely discharged therefrom before entering the next single set, so that there may be none of the stretching tendency above referred to. To this end the endless conveyers are provided for carrying the plates to the next roll after having been released by the rolls th rough which they have just passed.

The process employed is one continuous treatment from the rough and unrolled stock to vthe thin and finished plates. In the old method of reducing these plates it has been necessary to heat and roll and double the plates, repeating the operation several time before the desired reduction could be attained. By my improved apparatus a more direct method is made possible.

The operation is simple, and the construction of the mill is comparatively cheap and inexpensive, while at the same time the millframe is of the strongest and most durable construction.

Having thus described my invention, I claim- In a rolling-mill, the combination of a double housing formed of a single casting, double roll-sets mounted therein, two or more'additional housings in line with the said double housings, roll-sets mounted in said additional housings, horizontal guide-rolls for the rollsets, endless aprons between the adjacent rolls, a brush mounted above one of the aprons,

and suitable operating means, substantially GRIFFITH W. JoNEs.
