Patented Nov. 13, 1906.

Application filed July 18, 1905. Serial No. 270,245.

To all whom, it may concern:

Be it known that I, WILLIAM MOUNTAIN, a citizen of the United States, residing at Alexandria, in the county of Madison and State of Indiana, have invented new and useful Improvements in Rolls, of which the following is a specification.

The invention relates to an improvement in rolling mills of the type designed for breaking down steel or iron piles for the production of merchantable bars.

The main object of the present invention is the production of a mill of the type described in which the pile is subjected to the action of a series of sets of alternately horizontally and vertical rolls mounted in a common line of feed and continuously driven from a single shaft.

The preferred embodiment of the details of structure of my invention will be described in the following specification, reference being had to the accompanying drawings, in which Figure 1 is a view in side elevation of a mill constructed in accordance with my invention. Fig. 2 is a plan of the same. Fig. 3 is a rear end view of the same. Fig. 4 is an elevation of the finishing-mill. Fig. 5 is an end view of the same.

Referring to the drawings, it will be noted that I have illustrated but two sets each of the vertical and horizontal rolls, though it is to be understood that I contemplate the use of as many sets as may be found desirable.

In the drawings, 1 represents a suitable bed-plate on which are supported housings 2 andv 3, the former supporting the horizontally-arranged rolls and the latter the vertically-arranged rolls, one of the housings 2 being secured to the forward end of the bedplate and the remaining housings alternating therewith to provide a pair of verticallyarranged rolls intermediate and beyond the horizontally-arranged rolls, as clearly shown in Fig. 1.

The housings 2 are formed on the adjacent facings of their vertical bars with guide-webs 4, extending vertically of the housings, and receiving and guiding blocks 5, in which blocks is revolubly mounted the upper horizontal roll 6.

7 represents the housing-cover, preferably of skeleton form and secured to the housing proper through the medium of screws 8.

Adjusting-screws 9 extend vertically through the transverse end bars of the cover,

being terminally secured to the journalblocks 5, the screws 9 having threaded engagement with said transverse bars to permit the vertical adjustment of the upper horizontal roll, as will be evident.

The lower horizontal roll is mounted in blocks 10, slidably engaging the vertical bars of the housing, the shaft 11 of this roll 12 being provided beyond the housing with a beveled gear 13.

The above description is equally applicable to both sets of horizontally-arranged rolls, it being understood that they are in duplicate throughout the mill.

The vertically-arranged rolls 14 and 15 are mounted in a housing 3, the shafts16 and 17 of said rolls, respectively, being mounted in j ournal- blocks 18 and 19, grooved at 20 to receive webs 21, projecting from horizontal rails of the housing, whereby said rolls are adjustable. Screws 20 and 21, terminally connected to the blocks 18 and 19, respectively, have threaded bearings in the end bars of the housing, whereby said blocks 18 and 19, and thereby the verticallyarranged rolls, may be adjusted to accommodate themselves to the size of the pile. The lower ends of the shafts 16 and 17 are provided with beveled gears 22 and 23, respectively, removably secured on said shafts through the medium of collars 24, as is usual.

25 represents the main shaft of the mill, being supported in suitable bearings in the bed-plate and directly underlying the first or forward pair of vertically-arranged rolls. Immediately beneath said rolls this shaft is provided with two reversely-arranged beveled gears 26 keyed for longitudinal movement upon the shaft 25 and arranged so that they engage the beveled gears 22 and 23 respectively, of the vertically-arranged rolls. In the transverse adjustment of the rolls to increase the distance between them the gears 26 are spaced apart upon the shaft 25 to insure the operative meshing with the gears 22 and 23, a spacing-collar or other device being employed to maintain the gears 26 spaced to the desired extent.

It is to be understood that the second pair of vertically-arranged rolls are also provided with a shaft 27 therebelow, having keyed pinions similar in construction and operation to thepinions 26 on shaft 25.

The shafts 25 and 27 are each provided at one end with a beveled pinion 28, arranged in longitudinal alinement and driven from a lower ends with beveled pinions 34, arranged to intermesh on opposite sides of its axis with the beveled pinion 31 on the shaft 35. The upper or remote end of each of the shafts 32 is provided with a beveled 'pinion 35, keyed upon the shaft and held in adjusted position with relation to the shaft by any suitable means. The pinions 35 arearranged to intermesh with the pinions 13 on the lower roll of the horizontally-arran ed sets, whereby said rolls are driven from t e main shaft.

36 represents a feeding-scoop to receive a' pile of welding hot iron or steel and direct the same to the first pair of horizontally-arranged rolls.

Figs. 4 and 5 represent the finishing-mill, which is designed to receive the material from the mill previously described. The finishing-mill comprises a base 36, from which rise standards 37, supporting the shafts 38 on the finishing-rolls 39. The shafts of these rolls are preferably mounted in bearing-blocks which are secured against independent movement under normal condition by set-screws 40, passing through the housing-standards, though it is to be understood that set-screws 40 may be adjusted when desired to permit a yielding movement of the rolls to accommodate thicker piles.

Intermediate the respective pairs of hori 'zontally and vertically arranged rolls are Shafts 32 are supported by bear mounted guide-rollers 41, revolubly supported in uprights 43, whereby to guide and to support the iron piles in transit from one set of rollers to the next.

The operation of my improyed mill is fully apparent from the above description taken in connection with the drawings.

vI-Iaving thus fully described the invention, what I claim as new is 1. A rolling-mill comprising a bed, three housings mounted thereon, a pair of rollers j ournaled in each housing, the rollers of the intermediate housing being arranged at right anglesto the'remaining pairs of rollers, a driveshaft arranged beneath and adapted to coop erate with the intermediate pair of rollers, and drive-shafts connected with the first-mentioned drive-shaft and geared to operate one roller of each of the remaining pairs of rollers.

2. A rolling-mill comprising a bed, independent housings mounted thereon, a pair of rollers j ournaled in each housing, the rollers of one pair being horizontally arranged and the rollers of the adjacent pair being vertically arranged, the shafts of the vertically-arranged rollers projecting below the housings and provided with beveled gears, a driveshaft beneath one pair of vertically-arranged rollers, beveled gears on said shaft to engage the gears on the roller-shafts, means connecting said drive-shaft with the horizontally-arranged rollers, an auxiliary shaft beneath the remaining pairs of vertically-arranged rollers, gears on said auxiliary shaft to engage the beveled gears on the roller-shafts, and a connection betweenthe power-shaft and said auxiliary shaft.

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

V WILLIAM MOUNTAIN. Witnesses:
