TABLE FOR ROLLING-MILLS, &c.

To all whom 'it may concern:

Be it known that I, JOSEPH FAWELL, residat Pittsburg, in the county of Allegheny and lState of Pennsylvania, a citizen of the United States, have invented or discovered certain new and useful Improvements in Tables for Rolling-Mills, &c., 'of which improvement the following is a specification.

Application Serial No. 331,177, filed June 27, 1907, describes and claims certain improvements infeed tables for rolling mills, said improvements consisting generally stated in a construction permitting' of the withdrawal of the feed rollers in a direction subs tantially parallel with the axes of the rollers.

The invention described herein relates to certain further improvements in that style or kind of feed table, and is hereinafter more fully described and claimed.

. In the accompanying drawings forming a part of this specification Figure 1 is a sectional plan view of a vportion of a feed table embodying my improvements; Fig. 2 is a side elevation 'on an enlarged scale of a portionf of the feed table; Figs. 3 and 4 are sectional elevations of opposite ends of a feed roller and its bearings, the lane of section being indicated by the line I -III Fig. 1.

The side plates or frames 1 are preferably provided at suitable intervals with openings 2 and 3 for the reception of the journals of the rollers. As shown in Fig. 1 alternate openin s `2 are sufficiently lar er than the jouina s 4 at one end of the rol ers 5 for the sleeves 6. The openings 3 however are made sufficiently large to ermit of the longitudinal removal of the ro lers through such openings in placing the rollers in position or removing them from the feed table. Annular blocks qs through the blocks being .made slightly larger than the journals 8 of the rolls to permit of the insertion of the bushings 9.

It will be observed by reference to Fig. 1 that openingsl 2V in one side plate or frame are opposite the openings 3 in the plate or frame so lthat alternate 'rollers wil be inserted or removed from opposite sides of the table.

By reference to Figs. 1 and 2 it will be seen that the annular blocks are provided with flanges 10 fitting against the outer face of the side plates adjacent to the openings 3 thereby limiting the inward movement of `the Iblocks. The annular blocks are held Specification of Letters Patent. Application filed April 3,- 1908.

from movement out of the openings in the side plates or flanges hy keys 11 engaging undercut lugs 12 on the frames and extending laterally into angular notches or recesses in the outer ends 'of the blocks as shown in Figs. 1 and 2.

By reference to Figs. 1 and 4 it will be observed that the rollers are provided at the inner ends of the journals 8 with shoulders 13 which bear against the flanged ends ofthe bushings 9, preventing movement of therollers in one direction. Movement of' the rollers in the opposite direction is prevented by the pinions 14 which are keyed on extensions of the journals after the annular blocks have been slipped onto the journals. Washers 15 formed in two sections are laced between the inner ends of the hubs o the pinions 14 and the faces of theannular blocks. These sections can be easily rc laced as they are held in position by the ocking keys 11 as shown in Figs. 1 and .Z. 'llhe annular blocks are recessed .for the lightness and also 'to provide an oil receptacle 16 in the upper poru tions of the blocks, which have filling necks 17 formed integral with the ortions of the blocks having the oil rece tac cs.

As shown in Fig. 1 a ternate rollers are driven from opposite ends vby pinions 29 on These shafts are supported by brackets 19 on the frames or side plates in line with the non driven ends of alternate rollers. These brackets are provided with slots 20 into which the shaft sections aremserted laterally one of the first inserted. After the shaft section has been adjusted to position the other brasses 22 are inserted and the holding blocks slid into the slots. These blocks are secured in position by wedge-like keys 23 which pass through openings through the up er and lower walls of the slots 20 as clear y shown in Figs. 1, 2 and 3. These brackets are provided with pockets 24 and 25 formin' oil rece tacles from which passages 26 an 27 exten to the bearings for the shaft and the journals of the rollers.

In the construction shown-herein, the pinions 14 can be secured in position on the extension of the journals before the rollers are placed in position in the side frames. When it is necessary to ,replace a roller of a feed 'table while in use the section of the shaft is uncoupled and the wedge keys 23 and locking brasses 21 being keys 11 removed when the shaft section a'nd roller having an annular block thereon and a the journals or portions of the roller between inion key thereto can be inserted. ,'It will the journals, the other openings being lie observed that new washers 15 can be insmaller than said parts and adapted to reserted by removing the locking keys 11, withceive and support the journals of the rollers, 4 out disturbing other parts of the feed table. annular blocks fitting said larger 'openings I claim herein as my invention: and adapted to receive the journals of the 1.
