IMPROVED ROLLEPrSTAND.

Specification forming part of Letters Patent No. 43,246, dated June 21, 1864.

To all whom "it m coy concern:

Be it known that I, HERVEY Warns, of Northbridge, in the county of Worcester and State of Massachusetts, have invented an Improved Gonstruction of Roller Stand; and I do hereby declare that the following, taken in connection with the drawings, which accompany and form part of this specification, is a description of my invention sufficient to enable'those skilled in the art to practice it.

My invention relates to stands, housings, or frames employed to contain such rolls as are used in mills or factories for reducing and shaping hot iron, and for other purposes, which require massive rolls to produce desired results, thepurpose of my invention being the production of roller-stands which offer peculiar facilities for the removal of the rolls th erefrom, so that one r a set of rolls may easily be changed for another, or may be taken out to be turned or faced anew, this removal and replacing of rollers from and in the stand consuming less of labor and time than similar operations called for in all other roller-stands heretofore made. r

Roller-stands were made prior to my invention substantially as follows: At each end of a foundation or bed plate upright pillars were fixed, two in number, at each end, on or between which the boxes for the rollers were guided and kept in proper position. A cap secured to the tops of these pillars tied those of eachend together, and the ends were sometimes stayed across each to the other by a suitable connection. Instead of the said pillars the stands were afterward made by having upright pieces each cast integral with one of the lower boxes, these uprights being two in number at each end of the bed, and being arranged with a space between them and suitably otherwise for the reception and guidance of the boxes for the top roller, and a cap was placed across the tops of the uprights at each end, the cap in both varieties of stands being used for connection thereunto of the means by which the position of the top roll was controlled. To remove the top roller from either of these stands it was necessary to remove the c p from the top of each upright, and with it all the means for controlling the position of the top roll; then the boxes of the top roll had to be hoisted up out of the uprights of the rollerstand, and then the top roll, all of which consumed much time and expenditure of power, the parts being very heavy. When the bottom roll alone required to be removed, all of the process just described had to be performed before the bottom roll could be removed by being raised up over the rights.

Another construction heretofore considererably in use was to cast the entire housing at each end in one piece and then place these upon a suitable bed-piece. In this construe tion it was necessary tohave the opening between the two sides or uprights of the housing large enough to pass the rolls in and out endwise through them, or else to take away one of the housings in order to get either roller in or out of the stand.

My invention consists in so constructing or organizing a rollerstand that part of the material which resists the rupturing tendency of the rolling operation shall consist of tiebolts made removable for the purpose of facilitating the change of rolls therein, substantially in the manner herein described.

My invention may be said to combine in a measure all the advantages of the old constructions without their attendant disadvanta-ges, and its embodiment is shown in Figure 1, which exhibits my improved roller-stand in elevation, while Fig. 2 shows the same in cross section, taken in the plane of the line 2: z, Fig. 1, and in elevation beyond.

The foundation or bed plate a and uprights b b may be made in one casting, the bearings for the lower roll being formed therein. The upper part of each upright is shaped as clearly shown in Fig 2, so as to contain sliding boxes 0 c, which form the bearings for the journals of the upper roll, the position of which boxes is determined by rotating the screws cl, these being tapped through the upper part of b and being hollow, so thatthe bolts 6 pass through the screws d into the boxes 0 and keep them always in contact with the lower ends of said screws, so that when the screws 01 are turned (1 )wn the boxes 0 will be depressed, and when they are turned up the boxes 0 will be raised, the collars f, formed on bolts 6, being in contact with the upper ends of screws 61.. The upper overhanging parts of each of the uprights is tied across to the lower partor bed-box by the bolts 9, these being so arranged that they may be raised or lowered from their normal positops of the uption,"where they take part of the strain which 7 represented as dropped into a pit made beneath the roller-stand for that purpose. When both bolts are so dropped, it is obvious that when the boxes 0 are raised the upper roll can beremoved easily, also the lower roll, and that by lashing or otherwise securing the upper roll to its boxes the lower roll can be removed alone, and that all this can be accomplished with great facility as compared with the difticulty experienced in the old construction in the act of removing the rolls.

It will be observed that instead of casting the two stands and bed in connection, as Ihave shown in the drawings, the stands may be cast separate and then made fast to a bed or suitable foundation. When the roller-stand is elevated, as upon legs or supports, from the floor or working platform, or where the bolts 9 are arranged to be drawn upward, the pit is unnecessary.

I claim- A roller-stand constructed or organized substantially as and for the purpose specified.

In witness whereof I hereunto set my hand
