normed-nine nrrnrarrcn Application filed August 13,1921. eerie! No. cancer.

To all whom it may concern:

Be it known that I, TOM WILSON, a citi-- zen of the United States,'and a resident of the city of Johnstown, county of Cambria, and State of Pennsylvania, have invented certain new and useful Improvements in Rolling-Mill Appliances; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it a pertains to make and use the same.

iffy invention relates to a rollin mill appliance or apparatus which is a apted to handle blooms and billets which arelapproximately square in section, with or without rounded corners, or slabs which are approximately rectangular with either square or rounded corners, and my apparatus is adapt- :d to deliver the same to the rolls or receive :he same from the rolls and turn the pieces on their lon itudinal axes as may be de """ed for rol mg, reduction or shaping in me difierent grooves of the null rolls.

My invention is particularly applicable to what is known as a two-high mill, which is provided with a pair of reversing rolls provided with approximately rectangular grooves therein and collars forming part of the side boundaries of said grooves, the

rolls being adapted to be moved apart or together to adjust the sizes of the different passes in the rolls.

In connection with the rolls 1s a parrot tables, one on each side of the mill, which are provided with a plurality of rollers aiilapted to be rotated in either direction or to be held stationary as desired, and these rollers are provided with collars or projections thereon and so spaced apart as to acrolled. In connection with the tables ll also provide a manipulator with an operating portion, which has a series of serrations or notches formed in the metal bars thereof, which are adapted to be moved upwardly or downwardly preferably by a partial rotation ers they are lifted by the manipulator and supported in the series of saw-tooth serrations thereof, and as the manipulator is lowered, the blooms," billets or slabs contact with the collars or projections of the table rollers and are turned on their axes as desired before entering the next pass. By reason of this arrangement the various passes of the rolls are kept in operation at all times which thereby largely increases the product and reduces the rollingexpense.

Although I refer to use a table with a plurality of ii ting rollers having grooves therein formed by the collars or otherwise,

I may use a stationary table forming a fixed structure havin projections between the ro- Figure 2 is a vertical transverse sectional elevation through the feed table taken on the line l[l-H of Figure 1; Figure 3 is a detail longitudinal sectional elevation of a portion of the feed table; Figure 4 is a detail sectional elevation through the movable joint links; Figure 5 is a detail sectional elevation through the pivoted end of the actuating bar; Figure 6 is a detail view showing one of the manipulator table rollers in side elevation with the billets turned a uarter of a revolution to the position shown in Figure 2 and shifted to the next groove in the rollers.

Referring now to the characters of reference on the drawing 1 are the longitudinal side base frames of the roller feed table upon which the table rollers 2 are rotatably mounted, 3 are the bevel gears on the ends of the shafts of the table rollers, 41 are the other bevel gears mounted .on the drive shaft 5 adapted to mesh with and. drive the rollers 2 by means of the bevel gears 3 mounted thereon, 6 are annular collars mounted on or forming part of the table rollers forming spaces or

grooves

7, 8, 9 and 10 therebetween; 11, 12, 13 and 14 represent blooms or billets in various stages of completion and '15 are the serrated or notched lifting. and lowering members of my manipulator, these bei provided with notches or serrations 16, 1 18 and 19 in of the actuating bar and the connecting i the upper surfaces thereof; 20 are spacing members secured between the lower portions of the lifting members 15 in order to maintain them in position and alignment so that they will operate together in pairs; 21 are the outer portions of the spacers and 22 and 23 are openings provided in the lifting members 15 and 20 as illustrated, and adapted to receive the wedges 24, which secure the lifting members 15 to the lower portion of the manipulator construction; 25 and 26- are the actuatin bars of the manipulator secured by bolts 27 to the member 20, these bolts also being provided with tubular spacin washers 28 as'illustrated; 29 are pivot b0 ts passing through the ends of the actuating bars 25 and around which they are adapted to be partially rotated, these bolts being mounted in the castings 30, which are secured to the channels 33 by means of the flanges 31 and the bolts 32 passing there through, while 34: is a longitudinal orizontal channel upon which the channels 33 are mounted; 35 are tie bars mounted on the tops of the channels33-at the side of the casting 30, bracing and connected to the longitudinal horizontal channels 34 by the bolts 36; 37 are pivot bolts pass ng through the movable ends of the

actuatlng bars

25 and 26, provided with washers or filler blocks 38 between these two members, and further provided with links 39 pivoted to the bolts 37, the ends of the links 39 being pivotall secured by means of the bolts 40 to the short rocker arms 41; 53 are longer rocker arms mounted on the rock shaft 42 provided with pivot bolts 43 near the ends of the upper legs thereof; 44 is a pitman pivotally mounted on the bolts 43 and 45; 46 are small crank arms mounted on the rotating shaft 47, which shaft is also rovided with a gear 48 which meshes wit a pinion 52 mounted on the shaft 55, which latter shaft 55 has mounted thereon a gear 49 which meshes with the pinion 50 on the end of the motor shaft of the motor 51; 54 are the rolls of the rolling mill provided with grooves therein as illustrated and mounted as usual in roll housings 56.

Having thus described my apparatus, I will now describe how it operates: The rolls 54 of the mill receive the bars, blooms, billets or slabs in the various passes thereof, which are delivered in the direction of and to the feed table and are there received by the rollers 2 thereof within the

grooves

7, 8, 9 and 10 formed by the collars of said rollers. After the pieces have issued from the mill and it is desired to transfer them to the next pass for further operation, the manipulator is moved upwardly and lifts each of the blooms, billets or slabs between the collars on the feed table rollers, and after this lifting operation is finished the manipulator is lowered and as this is done from the last the lower surfaces of the blooms, billets or slabs contact with the collars of the feed table rollers and the pieces are thereby feed rollers in the grooves thereof as shown by the fulllines. The manipulator bars 15 are then moved upwardly and these blooms or billets are lifted to the positions shown by the dotted lines, whereupon they slide down the serrations of the manipulator to the right, whereupon the manipulator is lowered, and as this is done the pieces contact with the upper edges of the collars and are turned substantially ninety 'de ees on their axes and delivered into t e next grooves of the'rollers in position tobe deivered to the next passes of the rolling mill for further reduction.

This process is continuous,

so that larger blooms, billets or or larger passes of the rolling mill and .slabs are successively deliveredfto the first are reduced to their final sizes as delivered 1,-

pass thereof. For example, a 7 inch m 8 inch bloom may be rolled to a 4 inch w 4 inch billet, this 7 inch x 8 inch bloom entering the table with its 8-inch side resting on the rollers, is transferred and turned ninety degrees on its axis and edged to enter the 7-inch pass by the saw-tooth manipulator member, which, as it rises, lifts the piece gradually and allows it to slide into or rest in the bottom portion of the serration, and then as the manlpulator is lowered delivers it to the next groove in the feed rollers, and as this is done the lower surfaces of the piece contact with the upper edges of the collars of the feed rollers, WhlCh turn the piece ninety degrees on its axis and delivers it to the next groove of the rollers and thence by rotation of the rollers to the mill, into which it is entered for further reduction.

Although I have shown and described my invention in considerable detail, I do not wish to be limited specific details thereof, asshown and de- 1 scribed, but may use such modifications in, substitutions for, or equivalents thereof as' are embraced within the scope of myinvention or as pointed out in the claims.

when my manipulator is moved u wardly it lifts the pieces from the tablerol ers and under certain conditions allows the, pieces to S e la y y g v y o the'bottom of to the exact and the serrations, thus Having thus described my invention, what I c aim and desire to secure by Letters Patent is:
