Specification of Letters Patent. Patented Sept 11, 191?.

Application filed June 20, 1916. Serial No. 104,711.

To all whom it may concern:

. Be it known that I, CARE N. REEsE, a citizen ofthe United States, and a resident of Alliance, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Manipulators for Roller-Tables; 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 appertains to make and use the same.

This invention relates to animprovement in an apparatus for manipulating rolled sections on roller tables, the object being to engage a billet, bloom, beam, rail or other section after being rolled, and deposit it on the table with its base substantially at right anglesto its original position.

l/Vith this object in view my invention consists in the parts and Combinations of parts as will be more fully described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in plan of my improvement; Fig.

2 is a view in vertical'section in the plane of the crank shaft; Fig. 31 is a view in end elevation and Fig. 4 is a view partly in elevation and partly in section of the worm and worm gear casing.

5 represents an electric motor ofany approved type, to the armature shaft 6 of which is keyed a gear-wheel 7 meshing with a larger gear 8 keyed to the shaft 9. This shaft 9 is mounted in suitable bearings,

those at one end, as at 10, being preferably connected with the motor casing, and those at the other end being carried by the worm and worm wheel casing 11. -The worm 12 is integral with or secured to the shaft 9, and meshes with-the wheel 13 secured on shaft 14- for rotating the latter, the direction 'of rotation of the shaft, being of course dependent on the direction of rotation of the armature shaft of the motor. 7

The worm and worm wheel, are inclosed within the casing 11, which latter also has bearings 15 for the shaft 14, the ends of the latter being mounted in bearings 16. The shaft 14L is located under a portion of the roller table, which is shown in dotted lines in Figs. 1, 2 and 3, and extends in the direction of the length of said table, and is provided at its ends with the cranks 17 on which the manipulators 18 are mounted to oscillate. The cranks are so located with relation to each other that the two manipulators 18, rise, fall and rock in unison, and the parts are so located and proportioned with relation to the roller table, that when the cranks are in. their lowest position, the manipulators 18 will be down and out of the way of a billet 01' other piece of work on the roller table.

The manipulators 18 are of Y-shape, and each is mounted at its lower end on a crank. The inner faces of the upper fingers 18 of themanipulators 18 are at an angle to each other, and when the cranks are at their lowest position, as in Fig. 3, these fingers are belowthe rolls, so as not to interfere in the slightest with the free travel of the billet, beam or other section on the table and over the fingers. n

The upper portions of the sides of the table 19, in theplane of the fingers, are cut away so as to permit of the free rise, fall and oscillation of the manipulator fingers, and as shown in Fig. 52, several rollers of the table are preferably located intermediate the manipulators so as to prevent any material drooping of the ends of the billet or other section being r0llcd,in its passage between the manipulators.

Each manipulator 18 is retained in its upright position by the fulcrum arm or link 20, each of which is journaled at its outer end to the bracket 21, and to its manipulator 18 at or near the juncture of the two fingers 18 When the cranks 17 are in their lowest p0- sition, both fingers of the manipulator are so disposed with relation to the frame of the table 19 and the rollers on said table, as not to interfere in the slightest with a section being rolled, irrespective of the width of said. section. As the shaft 1 1 rotates, the manipulators are moved upwardly, their lower ends moving in a circle with their cranks 17, while the portions thereof to which the fulcrum arms or levers 20 are connected, move approximately vertical. This circular movement of the lower end of each manipulator, together with the vertical movement of its fulcrum causes the fingers 18 to rise and rock, first in one direction crank passes the center and begins to rise,

the manipulator rises and at the same time is rocked on its fulcrum, thus causing the manipulator finger at the right to move to approximately a vertical position and the finger at the left to move approximately to a horizontal position and this movement continues through ninety degrees, or a quarter turn of the crank. During the quarter turn, the manipulator finger at the right, has moved up between the rollers with its upper end above the plane of the latter so as to engage and shove the section being rolled over to the left, and hasmoved to approximately a vertical position, while the finger at the left has been turned to approximately a horizontal position. During the next quarter turn ofthe crank the manipulator continues to rise but the fingers then rock to the left, thus bringing the manipulator finger at the left, up under the billet, bloom, or section being rolled, the said finger engaging the billet, etc., at the lowerleft hand edge and gradually turning the latter as diagrammatically illustrated in Fig. 5. When the crank has, moved through one hundred and eighty degrees, the manipu lator stands as in Fig. 2, except that it has been elevated the full throw of the crank,

and during the next quarter turn the finger ment of the finger at the left to a vertical position that the bloom is turned ninety degrees. Dur ng the next, or last quarter turn the left hand finger moves away from the bloom, and the finger at the right moves up until they are are in position for the free movement of the bloom on the table, the

manipulators remaining at rest until set in motion by the operator.

The manipulator may be used in connection with either stationary or movable roller tables, and by employing cranks the manipulators are brought back to their original position without reversing the motor. If however it be desired to turn the piece in the opposite direction it may be readily done by reversing the motor soas to impart a left instead of a right hand'movement to the cranks.

Copies of this patent may be obtained. for five cents each, by addressing the Washington, I); G. V H

It is evident however that the movement of the manipulators may be obtained by means other than the cranks and fulcrum arm or links, hence I would have it understood that I do not confine my invention to the, construction shown but consider myself at liberty to make such changes as may fall within the scope of the claims.

Having fully described my invention what I claim as new and desire to secure by Letters Patent, is v 1. An apparatus for edging or turning work on a roller table consisting of a -manipulator having fingers adapted to be projected upwardly so as to engage the work on the table, a vertically movable fulcrum for said manipulator, and means for moving the lower end of said manipulator in a circle.

2. An apparatus for edging or turning work on a roller table consisting of a manipulator having two fingers approximately at right angles to each other, meansfor moving the lower end of the manipulator in a circle, and a vertically movable fulcrum engaging said manipulator above the moving means whereby the manipulator fingers are rocked as the manipulator is raised and lowered.

3. An apparatus for edging or turning work on a roller table consisting of a Y shaped manipulator, means forimoving the lower end of said manipulator in a circle and a vertically movable fulcrum connected.

with said manipulator intermediate its ends.

4. An apparatus for'edging or turning Work on a roller table consisting of a shaft having rotary cranks, manipulators each having a bifurcated upper end, and" journaled at its lower end on a crankwhereby the lower ends of the manipulators will be moved in a circle, and a fulcrum arm for each crank each fulcrum arm being pivoted at its outer end and having a journal connection with itsmanipulator abovethe connection of the crank with the latter.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses; V p, CARL NORh IAN-REESE.
