FEED-TABLE MECHANISM.

SPECIFICATION forming part of Letters Patent No. 704,890, dated July 15, 1902.

Application filed June 29 1901.

Be it known that I, THOMAS MORRISON, of Braddock, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Feed-Table Mechanism, of which; the following is a full, clear, and exactndef-l scription, reference beinghad to the accoms panying drawings, forming part of this speci-T fication, in which Figure 1 is ,a diagrammatic top planview showing feed-table apparatus constructed in accordance with my invention. Figs. '2 and 3 are cross-sectional views of the same, on'a larger scale, showing the parts in twodififerent positions. Fig. 4 is a cross-sectional view showing a special device hereinafter referred;

1 to; and Fig. dis a top plan view, on a larger scale, showing a shifting dog.

My invention relates to feed-tables for roll-. ing-mills, and is designed to provide improved mechanism for separating one rolled section from a group and moving it to a point later ally separated from said group; and, further,- to provide mechanism for moving one section;

laterally into the group at the same time that counterweighted lever is pivotedto the other one section of the group is thus separated from it.

The invention is more specially adapted to the apparatus described in my United States Patent No. 654,100, though it may be applied to other mills and in other connections.

In the drawings I show a feed-table having a longitudinal series of feed.-rollers;2,' ,which may be driven by bevel-gear connections. 3. with a driven shaft 4:. Thesefeed-rollers are in line with a pass of the rolling-mill which feeds the metal forward upon them, and par-' allel with such set is another'set of feed-roll: ers 5, which may be driven by bevel-gear connections 6 with a driven shaft/Z. Transverse supports 8 8 are arranged impairs extending transversely between thelines of two sets of feed-rollers, these supportshaving their intermediate portions slightly above .the' level of the rollers, while theirend portions are inclined down topoints-below such levels.

To transfer the metal laterally upon the transverse supports 8, I provide a series of sliding carriers- 9, having lateral flanges 10, which are supported on guideways 11 between each pair of supports 8. To the ends of each otherwise occur.

derial No. 66,482. (No modal.)

carrier'are secured flexible connections 12 and 13, which are secured, respectively, to

wheels Maud pulleys 15, carried on counterweighted bell-cranks 16. The wheels 14 are mounted upon the common shaft 17, which is provided with a pinion 18, intermeshing with rack 19, which may he reciprocated by motor 20. By actuating this motor in either direction the shaft 17 will be rocked and the carriers will be moved transversely across the feed-table.

Each carrier is provided in its rear portion adjacent to the rollers 2 with a pivoted dog -21, the lower part 2P of which is counterweighted to hold it normally in the position This bevel is provided so that if through accident the entering rail-section or other section should strike the dog it will move up the inclined face 23 and depress the dog and pass over it, thus avoiding the injury which would A swinging selector 24 in the form of at end of each carrier, such selector having a gripping-notch 25 and beyond this an inclined 'nose portion 26. The counter-weighted end 27 of-the lever-tends to hold the nose end of the selector elevated, as shown in Fig. 2, the other end resting against a stop 28 on the carrier.

In the operation of the apparatus a group of rolled sections 29 is constantly maintained on the intermediate part of the table, and after an additional rolled section has been fed forward on the rollers 2 the carriers are acreached. The counterweighted portions of these levers constantly tend to force up the nose portions, and when these nose portions pass this last section the selectors rock upwardly and cause their recessed portions to engage the last section of the group, as shown in Fig. 2. As the motion of the carrier continues this side section of the group is carried forwardly over the supports 8 and onto the series of rollers 5, and the selectors are disengaged therefrom by depressing plates 30, which engage their nose portions, as shown in Fig. 3. A section is thus transferred from the group to the rollers 5 at the same time that another section is added to the group and the group moved laterally, and the carriers are then moved back to their original position ready to repeat the operation.

I have shown the invention as applied to the rolling of rails, and such rails are rolled in sections of different lengths, some sections being of the length of three rails and some of the length of two rails. It is apparent that with the system above described when a tworail section succeeds a three-rail section in the group as the selectors move forward to separate the two-rail section one or more of them beyond the length of this two-rail section would engage the next three-rail section back of it, and thus prevent proper operation. To prevent this abnormal action, I provide at the point marked noon Fig. 1 a swinging lever 31, having a blank-section 32 at its end and which may be depressed when desired to take the place of that portion of the two-rail section which would normally be engaged by a selector if it were of a three-rail length. This lever is under the control of the operator and may be swung in any desired manner. I have shown for this purpose an electromagnet 33, the core of which is connected by a link 34 to a lever 31, which is pivoted at the point 35. The operator in the pulpit who controls the movements of the carriers also controls the movement of this lever by a suitable switch connection, and when on moving the carriers to separate one of the sections he sees that such section is a two-rail section he depresses the lever 31, and thereby holds down the nose of that selector which would otherwise engage the head of the next rail at this point, and thereby holds this particular selector out of action during such movement. If the next section is of threerail length, the lever may then be lifted, so that on the next movement of the carrier this selector will operate in its normal way.

The advantages of my invention result from the withdrawing of one of the rolled sections from the group and its lateral transfer to another part of the table. Where the whole group was fed forward, as in the form shown in my patent above referred to, some difficulty was experienced in preventing more than one rail from being fed from the group to the transfer-rollers and this difficulty is entirely overcome by the present invention. The inclination-of the face of the rear dog is of advantage in preventing accidents, and

the whole system is simple, easily operated, and not liable to get out of order.

The selectors may be arranged in front of the group in such a way as to move forward and then pull a section away from the group instead of pushing it, as in the form shown, and many other changes may be made in the form and arrangement of the parts without departing from my invention, since I consider myself the first to use the automatic selector, which moves one section from a group to another point on the table.

I claim 1. A rolling-mill feed-table having a selector arranged to engage a single article in a group of articles and separate and move it laterally from the group of articles, and mechanism for moving the selector transversely of the table, substantially as described.

A rolling-mill feed-table having a trans versely-movable carrier, a selector mounted on the carrier and arranged to engage a single article in a group of articles lying on the table and separate and move it laterally from such group of articles, and trip mechanism arranged to automatically disengage the selector from the article after it is separated from the group; substantially as described.

7. A rolling-mill feed-table having transversely-movable selectors arranged to engage a single article in a group of articles on the table and separate and move it laterally from the group, and controllable mechanism for preventing the normal action of one of said selectors; substantially as described.

' 8. A rolling-mill feed-table having a transversely-movable carrier, 3 pivoted pusherdog connected to the carrier and arranged to feed an article sidewise on the table and means for feeding metal longitudinally of the my hand. table, the dog being normally out of the line of feed and having an inclined face toward the entrance side, arranged to be contacted with by the article when the article being fed accidentally strikes said dog; substantially as described. 10
