FEED-TABLE FOR ROLLING-MILLS.

movements the following is a specification.

The invention described herein relates to certain lmprovementsin feed mechanism for the transfer of articles, such as billetestock,

from the reducing-rolls to the shearing mechanism, where suchstock is cut .up' into-bil lets; and the invention has for its object 'an arrangement of feed-tables and transfer mechanism whereby. provision is*made.-'for the storage of the-billet-stock while the shear mechanism is in dperation, thereby renderand claimed.

ing it possible to. operate the reducingrolls and shear mechanism continuously without re ard to eachother.

. n general terms, the invention consists in the'construction and combination, substan tially as hereinafter particularly described In the accompanying-drawings, forming a part of this specification, Figure 1 is a plan view showing the relative arrangement of feed-tables, &c., in my improved plant. Fig,

Fig. 4 is a top planview, on a; enlarged scale, of the mechanism for transferring the billetstock from the storage to the shear feed table.- Fig. 5 is a'transverse section, the plane ofsection being'indicated by the line 'y 3 Fig. 4. Fig. 6 is a sectional elevation of the rear end of the storage-table, showing the backtop. Fig. 7 is a transverse section on the ,p'fime indicated by the 'line 2 c, Fig. 4. Fig. 8 is a top plan view showing a modification in the relative ar ngement of the storage and shear tables; and Fig. 9 is a sectional elevation of the same, the plane of section being indicated by the line w m, Fig. 8.

In modern rolling-mill practice the reduction of ingots to billet-stock can be effected more rapidly than the shearing of such stock into billets. This difliculty has been overcome by so constructing the shear mechanismthatztwo 'or' more pieces of billet-stock can be sheared at the same time, but difficulty has been encountered in taking care of pieces of'stock; which are being rolled while "other pieces are being sheared and in l'ilflllS'. ferring the second lot of stock to the shear-' table.

encountered in the productiono'f billets, &c., I arrange what I term, for convenience, a storage-table A in line with the deliverytable of a rolling-mill, so that billet-stock maybe delivered directly to the storage-table without handling. This storage-table consists of an apron 1 for guiding the billet-stock,

. In order to overcome the difliculties now a series or positively-driven rollers 2, and a sto device D at the rear end of the storagetab e. The stop device consists of a thick plate 3, attached-to bars 4, which are movablymounted in a backing plate or abutment 6. Springa'fl are interposed between the plate 3 and the abutment 5, thereby forming ayielding stop for the billet-stock, as shown in Figs.

1 and 6.

The mechanism employed for shifting the billet-stock from the storage-table A to the shear-table B consists of a series of supporting-frames-7, arranged intermediate of and parallel with the rollers 2 of the table, and a like series of slides 8, mounted on said supportingeframes. The slides 8 areslotted longitudinall'y to permit of the adjustment of the blocks 9, which are mounted on the slides,

as shown in Figs. 4 and 5. The slides are connected by links 10 to the ends of arms 11,

keyed to the shaft 12, which is mounted in suitable bearings parallel with the table A. The shaft'l2 is oscillated to shift theslides by a fluid-pressure cylinder 13, whosepiston is connected to arms 14 on the shaft, as shown in Fig. 1. The 'slots in the slides 8 are made of sucha length that the-blocks 9 can be shifted from a position a little to one side of the pass at one end of the reducing-rolls to a-corresponding position with relation to a pass at the opposite ends of the rolls, thereby reducing the length of stroke of the slides :08

when passes at the ends of the reducingrolls nearest the shear tables are being employed.

In order to prevent billet-stock from being fed onto the storage-table while the transfer mechanism is being, operated to shift stock onto the shcant'able, in which case the billet coming onto the storage-table would pass behind'th'e'blocks 9, a gate is arranged transverse of the storage table near its front end, as shown in l igs. 1, 2, and 3. This gate is arranged between guides 16 and is shifted vertically by an arm 17 on the shaft, said arm being connected by a link to one end of a lever 1.8, the opposite end of which is con neoted to the lower end of the gate. This gate-operati'ng mechanism is arranged so as to raise the gate into the line of movement of anybillet-stock from thefeed-tsble of the rolling- 51 transfer mechanism toward the 'shear table and thereby'preventing any movement of billet-stock onto the storage-table w'n-ile stock is being shifted from the storage=tab1e to the shear-table. Y

'lhe shear-table consists of a series of positi'v ely-driven rollers 19, so arranged that one end of at least a portion of therollers will projecta'short distance between the rollers 2 of the storage-table, so that the billet-stock will be supported in part by the rollers 19 before-being ghitted entirely... t0m the rollers 2, as shown in Fig. 1. vAsthe rollers 2 and 19 are so mounted that the upper portions of their same horizontal plane, it is'preferrefl that the ends of the rollers 19 projecting between the rollers 2should-be beveled, so that they out of the billet stoc k. The shear me-- m ,G, which is arranged at the end of i ableB, may'be of any suitable construction. i v y 1 I Asq hown in Figs. 8 and 9, the shear-table 6 may bear-ranged in line with the storagetabig, in which eason movable stop E is sub- .stituted for the stationary stop 1). This movable stop is constructed asregards the upper portionthe same as the stop D, and consists of n :plate 3, supported by bars 4, mounted i'na' backing plate or abutment 5, which is,

secured to the'npp'er endof the fluid-pressure cylinder 20.: v

8 and 9 two guide- rails 23 and 24 are arranged along the ends of the. rollers 19 of the sheartable, the ends of said rails adjacent to the storage-table being bent outwardly, so as to properly guide the billet-stock onto the sheartable.

In operating myimproved plant the blocks.

Simultaneous with this movement of the slides the gate 15 is raised, as hereinbefore stated, to preventthe movementof another piece of stock onto the storage-table until the return of the slides to normal posi- *shifted so as to be out of'the way of succeeding pieces. This operation is continued until the desired number of pieces has been ar- This batch is then shifted by a longer movement of the slides onto the shear-table B, whereby the batch is fed to the shears. While the first batch isbeing cut up, a second batch is being collected on the storage-table. As soon as the first batch has been out up or sufficiently so as to permit a. second batch being shifted onto the shear-tables the second'batch is so shifted by the slides. Y v

Itis characteristic of my improvement that when the rollers of the rolling-mill deliverytsble and the storage and shear tables are continuously rotated the onward movements of the billetsstock are eheckedvwhen necessary by the interposition of a suitable stop, and during such arrest of movement the rollers simply rub against the under sideof the article, so that the rolling of the ingots to clear. If the capacity of the shear mechanism is equal to that of the rolling-mill the table A is used to transfer the billetstock from the rolling-mill table to the shear-table.

Iio

In operating the construction in Figs. 8 and 9 each piece of billet stock is shifted laterally to be transferred to the shear-table the stop E is lowered, thereby permitting thez'stoc'k to be moved longitudinally onto the shear-table I15 on the storage-tablil out of. the wayoi the next succeeding'piece; but when the stock is by the rollers of the storage and shear tables.

While it is possible and sometimes preferableto operate the rollers of the storageand shear tables continuonslygthey may be so connected to the driving mechanism that their rotation can be stopped when not 1e qnired as', for example, the rollers of the storage-table can be stopped after one piece has been received-until another piece is ready for delivery thereto-and the rollers of both tables can be stopped during the transfer of stock from the storage to the shear table.
