To all whom it may concern:

Be it known that 1, WILLIAM L. JONES, a

, citizen of the UnitedStates, residing in New ark, Park View Section, in the county Bf Essex and State of New Jersey, have invented certain new and useful Improvements in Rolling-Machines, of which the following is a specification.

The invention relates to im rovements in rolling machinesyby means 0 which metal may be rolled into sheets.

The objects of the invention are to render drawings, which show two embodiments-of the invention, in which Figure 1 is a longitudinal section of a ma- 'hine embodying the invention. Fig. 2 is an end elevation; Fig. 3 is a transverse section on line 3-3 of Fig. 1; Fig. 4 is a horizontal section-on line 44 of Fig. 1, looking upward; Fi 5 is a horizontal section on line 55 ofFlg. 1, showing the table in'full lines, also the driving mechanism in full lines; Fig. 6 is a top view of a modification; and Fig. 7 is a sectional view thereof. In all the several views, like parts are designated by the same reference characters.

In carrying out the invention, I provide a. platen 1, and a table 2, the parts being carried within aframe 3. This frame is provided with a top4, connected to the frame by means of bolts 5 which are set up with nuts 6.

' Mounted upon the frame is a horizontal shaft 7 within the bearings 8. Theshaft extends beyond one end of the frame some distance as shown in-Fig. 1, the free end being sustained by a support 9 carrying a bearing 10 thereon. p

The table. 2 is supfported upon a sliding frame 11, by means 0 a pin 12 so that itcan be freely rotated thereon. Between the frame and the table is acircular set of balls 13. The sliding frame is supported upon a platform '14, having two sets 0 'str ht ways 15, within which. two straight sets "0 balls 16 are carried. This frame is adapted to be rehaving an upper entrance pipe 35, and

Within this cylmciprocated in a rectilinear manner upon the two straight sets of balls by mechanism which will be described.

The-table 2 is adapted to be rotated by the following mechanism: The shaft 7 is supported within a bearing 17 on the sliding frame, and is held in position by means of a collar 18. The shaft 7 carries a beveledpinion 19, which intermeshes with the beveled gear 20 on the table 2-. shaft 7 through the intermediary of the beveled pinion, and beveled gear, the table 2 may also be rotated. The table is reciprocated by the following mechanism: A connecting rod 21 is coupled to the sliding frame 11 by means of a pin 22.

trio and an eccentric strap 23.- The eccentric is carried upon the eccentric shaft 24, which is mounted in bearings 25. This shaft carries aworm gear 26. An auxiliary shaft 27 carries aworm 28 which engages with the worm gear 26. Collars 29 provide for the thrust upon the auxiliary shaft. The auxiliary shaft extends outside of the frame 3, and is supported upon a standard 30, carrying a bearing. Inside of the standard is a gear 31, which intermeshes with a pinion 32 carried by the shaft 7.

The shaft 7 is rotated by a gear33, which enes with apinion (not shown), and by means of which the entire mechanism is put in rotation. The pinion 32 is shown as havim twice'the width of face of the gear 31, and the pinion which en ages with the gear'33 is one-halfthe width 0 face of such gear. This is desirable as the shaft 7 is shown as cap able of being reciprocated a distance equal to'the throw of the eccentric, which. distance is shown to be about one-half the Width of the narrower gear, so that the gears willalways properly intermesh. If the amount of throw of the eccentric is varied, the width of the gears should be properly proportioned so that they will always have the face of the narrower gear in mesh.

The top 4'is provided with a cylinder 34, a lower entrance pipe '36. derworks a piston 37 which IS'GOIIDGOtGd to the platen, and by means of which the platen is moved up or down, with any desired amount of pressure. The cylinder is pro-. vided with a cylinder head 38 and the piston with packing rings 39. By permitting the entrance of water under pressure orsteam through the pipes 35 or 36, the piston may be p The other end of the connecting rod is provided with an eccen- By rotating the lot the metal which is being rolledout between the platen and table. The balls work more effectively .upon iron thando rolls, as they do not have a tendency to cause the iron to creep ahead of the rollingssurfaces, as is the case with rolls. The ba are held in position when the platen is raised, by retaining rings 41. In order to prevent the platen from rotating, it is provided with ears 52,

which engage within ways 53 formed within double top 43.

the frame 3.' These ears and ways permit the platen to be elevated or depressed, but

Will]. prevent it from rotating. In order to give eater'strength to the frame 3 immediate y under the sliding frame 11, it is provided-with strengthening webs 42.

1 -Another way of carrying out the invention is shown in Figs. 6 and 7. In this view a double top. 43 is provided having stre hened webs 44 across the upper face. In 'eu of the piston 37 a screw 45 is provided, this screw engaging within a; worm wheel 46 mounted within ball bearings .4747 on the upper. and lower sides thereof. These ball.

bearings engage within the two parts of the A motor 48 is carried upon a support 49, on( one side of the top, and its sh 50 is provided with a worm 51' which engages wit the worm wheel 46. By this means the screw 45 may be rotated at any speed desired, and by means of the motor 48,

. I the platen maybe elevated or depressed.

- At the .same time the shaft.

In theoperation of the machine described, the platen 1 is first elevated a sufficient distance to permit the...metal which is to be rolled to be placed upon the table and under the platen. Pressure is then applied to depress the platen either by admitting steam or water under ressure through "the pipe 35, or by rotating the motor'48, or by operating any other means provided for this purpose.

7 is rotated,

which rotates thetable 2, and at the sametime thro h the a ency of the ears 31 and 32,t e sha 27 am? worm 28 an worm gear 26,'t e eccentric 23 is rotated,.and through rod 21, the slide The extent of ing frame 11 is reciprocat movement the sliding'frame is sufficient to cause the balls to travel above the latenin an irregular path, so that the balls come into contact with every portion of the metal which .is to be rolled. In order that the rolls may not travel in regular paths, the beveled 'ge'ars19 and 20 and the eccentric 23 can be so lEoportioned as to cause the paths of the 'ba to be irregular.-

The platen may be elevated a suificient' distance above the table to permit the insertion of a puddle ball, so that the sheet iron may be obtained withbut a 'single heat.

This elevation of the platen is made possible owing to the'design of the machine whereby the table both rotates and reciprocates, and the platen serves but as a base against which the 11'011 is rolled;

The sheet iron obtainedis much superior The material advantages inci ent to the use of balls are many. Balls will roll in every direction, while rolls cannot turn in any direction except at rightangles to their axis. When moving in other directions, they drag upon the metal. In consequence,

by employing balls as one of the rolling surfaces, the: metal is uniformly rolled in every 'direction, without any dragging action of the rolli surface upon the metal.

her advantage incident to the use of balls is that they are in contact with the en tire surface of the metal. A series of rolls would be in contact with the centerline only of the reciprocating table. It will be noted that the balls roll the iron out in a'series of spirals .each forined of spirals. The puddle ball bei started in the center, will be -gradually rol ed to the thickness desired. reduction in thickness will be accompanied by an increase in area, which increasewill be developed h'om the center outwards, as the balls are rotating while the metal isreciprocated. The movement upon the balls-will be in the form of a spiral, and as the metal is being forced outwards constantly, the s iral formed by each ball will become a arge spiral formed by the rotation of the metal. On account, therefore, of the balls engaging in all directions and at the center,

face of the metal being rolled, will be more thorcughly acted upon, and the rolling will be more complete than if the action was done by rolls.

In accordance with the atent statutes I have described the .princip my invention, to ether with the apparatus whichI now consider to be the best embodimpnt thereof; but I desire it understood that theap aratus shown is only illustrative, and

that t e mventio'n. may be carried out by other means.
