HANGING- THE FORE-PLATES IRON-ROLLING- MACHINERY.

Specicaton of`Letters PatentNo. 10,524, 'dated Ilebruary4 14, 1854'.

To all whom t may concern.'

Be it known that I, JACOB REEsE, of Sharon, in the county of Mercer and Stat-e of Pennsylvania, have invented a .new and useful Improvement in Machinery for the Rolling of Iron; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed drawings, forming part of this specification, wherein- Figure l, is a perspective view of that part of the machinery of a rolling mill to which my improvements are to befapplied, showing the fore plate in its place in front of the finishing rolls, and the upper roll, b, not connected by the coupling with the shaft of the roll d. Fig. 2, is a perspective view of the same machinery, the uprights of the frame work being removed so asvto show Vthe details of the machinery more distinctly, the fore plate being thrown back from the rolls; the scouring board being in place, between the rolls, and the rollrb being connected by the coupling with the shaft of the roll a. Fig. 3, represents av self `supporting coupling. Figs. 4, 5, 6 and 7 represent the several parts of Fig. 3` detached.` Fig. 8 rep-k resents the old kind of coupling. Figs. 9, 10, and l1 represent the several parts of the old kind of coupling, detached.

In the several drawings the same letters refer to similar parts of the machinery.

My invention and improvement consists in connecting the fore-plateto the frame work which sustains the rollers, by adding to it arms which work on a bar or brace, as a center, thereby enabling the fore-plateA to be drawn away from the rolls or brought to its place again by simply turning it on its center and avoiding the delay of re-V moving the guides, the fore-plate and the rest bar, as is necessary on the old plan, whenever the rolls are to be scoured..

In order to explain fully the nature of my invention, it will be necessary to explain the present arrangement of the machinery l used for rolling and finishing, and the difficulties which my improvements are dethe frame a and a where it is connected withthe neck of another roll d toV which roller ai, or others similarly connected with it, motionis communicated from the steam engine or other motive power. The coupling shown in the drawings as connecting the necks of the rolls b and d is of the ordinary kind and is thus constructed. rIhe ends of the necks of the rolls to be connected arey made of similar diameter and shape, being squared or of anyusual and convenient shape, other than circular. Between the extremities of these rolls is placed a short connecting piece e, which is of vsimilar diameter and shape to the ends ofthe necks of the rolls b and d.

Two rings or boxesof iron f, f' are placed on'l this co-n.

necting piece, the .inner surface of which is a counterpart of the shape of j the necks of the rolls b and al', and which V fits said necks, and connecting piece, ex-

actly, andv yet will: slide back and fort-h from the necks to connecting piece e. Now when..

it is desired to couple or connect theV rolls b" andai the coupling just described 'is' placed between the necks` of the rolls to be rgeared together, and the rings or 'boxes f and f are slid apart along the connecting piece e, so as to cover the joints between the plece @,and the ends of therolls b andai.

.The rings are kept-fat the right distance apart by a strip of wood Vor iron g, Vtied laround the connectingl piece e. v The rolls` b and dare thus so connected 'that therevOlu-V tion' ofthe roll d" carries with it the roll Z2', butv if it be desired to disconnect them, it is necessary-to yremove Vthe separator g, and draw the rings f, f, Vtoward each other on the connecting Vpiece e, which leaves the coupling withoutany support, Aso that .it

'must be entirely lremoved until it is desired,

again to connect the' rolls b and d. V'Iodo all this requires the whole machinery to be stoppedwhich causeskgreat loss of time.

The upper finishing roller, 5,(is kept in its place o-ver the lowerl roller b', by the bearings or half journal` boxes 71 the journals off the roll b havingno lower bearing, as-it rests on the roll b', and whenin use itis not in` gear withfany other roll", but is turnedn asv a friction roller by its contact with the lower roller, or with the iron passing over the lower roller. It is necessary-that the Lipperl roller shouldv not be geared to any other shaft or roll, so that it may revolve evenly WithV the lower rollerY b, because if the upper e, f, g, before described, but as the coupling roller had motion independent of what it obtains from Contact with the lower roller and there was the slightest4 variation ind-V would be about 8 times a day. This is do-nel by placing thevscouring board z', with oil Vand emery upon it, between the rolls b and b', and causing them stillto revolve. (See Fig. 2.) Now the moment the scouring board z', is placed thus between the rolls, the friction of the rollb on the roll b, by which the latter was turned, ceases, and the upper roll Z) will stand still unless it be con- ,nected with the shaft of a working roller (Z, along side of it. This has 'heretofore been done by means of the ordinary coupling has to VYbe removed and brought back each time, and the machinery has to be stopped it becomes a serious hindrance. This is obviated by the use of the self sustaining coupling shown in detail in Fig. 3, and Figs.

4, 5, 6, 7 le is the box (of the shape shown in Fig. 7 and hollow throughout), one end being shaped to fit over the neck of the roll and the other end having a cylindrical bore, Y

to receive the end of the spindle Z a key m which passes through the box 7e at right angles to its axis serves toseparate the neck of the roll and the end ofthe spindle, and to keeppthe box 7c, in place, thus answering the purpose of the spreading block goin the ordinary coupling. The box 7c has a groove cut inside of it along the cylindrical bore, to receive a `corresponding rabbet `on the spindle. The spindle Z is a cylindrical shaped piece, suficiently long to connect the ends of the rolls to be coupled. The rabbet n forms a key, which 'tting into the groove in the Vbox k, causes the spindle to revolve with the roll towhich the box is attached. The other end of the spindle is inserted ina cylindrical bore in the box 0` which has crab lugs,'to fit into the lugs of the sliding crab p VThe box-0, has also a key m', similar to that'in the box'k, to keep the box in its place. The rabbet or key n. does not extend quite far enough `on the spindle to reach the box o, but approaches near to it; the spindle therefore turns freely in the box o, (by which and the box 7a it is supported) without carrying'the box 0, or the roll to which it is attached, with it. The sliding crab p which has lugs to ucorrespond with those on the box o, has a cylindrical bore throughout so as to slide evenly on the Aspindle and has a groove to receive the key 1t, so that the crab cannot turn around on the spindle,.but is carried around with it.

Now when the several parts are inthe po- Vone frame to the other.

time.

sition shown in Figs. 1 and 8, the spindle and crab are supported by the boxes Zc and Vo, and the roll to which the box '7c is attached can revolve, (and with it the spindle Z and crab p) without affecting the box' 0 or its roller Z2, and at the same time the spindle Z,

.by enteringthe bore of the box o, within which it turns freely, supports the roller b, without the use of a bearing under the journal of the roll b, which would otherwise be necessary. Now if it is desired to couple the roll Z9 withthe roll Z,it is done by simply sliding the crab p until its lugs interlock with those of the box 0. VThe rabbet 'n extends so far Vthat the crab 29 is still over it and as the spindle therefore cannot revolve` without carrying with it the crab y), which is now interlocked with the box o, the coupling is complete. :The connection can be at once brokenby sliding back the crab p far eno-ugh to release the lugs of the` box 0.

The advantage of this form of coupling is that it is sustained without any additional bearing between the coupling and one of the rolls to be connected, as is ordinarily required where couplings are used, and is not detached from the rolls by the act of throwing them in or out of gear, and that it can be used without-any stoppage `of the machinery.

In the drawings Figs. l and 2 g is the fore-plate, and 1, r, are the guides, placed before the rollers, to aid in feeding in the iron to be rolled. Fig. l, shows the foreplate and guides in their right place. The fore plate is usually inserted in grooves in the frames a, a which support the rolls,

and lies upon a rest bar, which extends from y In orderto insert the board z' for scouring'the rolls, it is necessary on the old plan of construction to stop t-he machinery, and unscrew the guides from "the fore-plate, and remove the fore plate and rest bar. p This `is `a tedious and diHicult job, andhas moreover to be done about eight times aV day and causes a very 1 serious expenditure `of` labor and loss of serving as a brace tothe frames, and making the pivot or center on which these arms turn. I also add a lug u, to each side of they fore plate g, which, when the fore plate is in the position shown in Fig.l l, rest against the outside ofthe frames a, a and act as stops to prevent the fore plate being drawn tooclose to the rolls when the iron is passing over it, through the rolls. When itis desired to insert the scouring board between the rolls all that is necessary is to turn the fore plate on its arms, thusldrawing it away All this I `savelby my arrangement from the rolls as seen in Fig. 2. It may readily be replaced again, by simply-raising it up, When the operation of scouring is complete, and the rolls b and d (which had been connected by the coupling for the purpose of scouring, to impart motion to the roll ZJ, which had otherwise been locked by the action of the scouring board) are now disconnected by sliding back the crab p and the machinery is again itted for use. Thus the operation of scouring the finishing rolls is accomplished Without stopping the machinery for a single moment.

The other parts of the drawings are the usual appendages to similar machinery in a.

rolling mill, and need not be particularly described.

Having thus described my improvements in machinery for rolling iron and other metals What I claim as my invention and desire to secure by Letters yPatent is not` the scouring of rolls as described in the.v

foregoing specification, nor yetthe coupling of the upper roll When the rolls are to bel scoured and uncouplingit When they are in use. But l What I do claim as my invention is'-` The hanging thev fore plate of a rolling vmill on centers, placed either above orv below the level of the rolls, by adding arms to the fore plate, Working on a bar or on pivots,r`

for the purposeof removing the fore plate out of lthe Way When the rolls are to be scouredlvvithout detaching it fromthe frame ofthe mill, substantially in the manner here- 35 Y
