To all whom it may concern.-

' specification, in which- Figure 1 is a side elevation, partly in sec` tion, showing a portion of my improved con- -veyer. Fig. 2 is a cross-section on the line II II-of Fig. 1. Figs. 3 and t are detail views of the eccentrics which I employ. Fig. 5 is a view showing the driving mechanism for the main shaft. 'Fig` 6 shows a modification, and Fig. 7 is a plan view of the same on a larger scale.

' The purpose of my invention is to provide means for conveying metal from one part of a mill to another.- It is especially adapted to convey hot pieces of metal and simultaneously cool them in their passage.

' The mechanism is characterized by simplieity of construction and economy in maintenance and operation, which areof great importance in a machine of thiskind.

The drawings show the preferable construction of the apparatus; but those skilled in the art will be able to modify it in various ways.

The conveyer comprises a series of xed rails 2, s et parallel to each other and constituting a cooling-bed and conveying-table. They are supported upon suitable posts or standards 3, to which they are fastened by clamps 4 to assure rigidity of construction. The moving mechanism consists of rails or beams 5, which are set in the spaces between the fixed rails 2.and are preferably connected by cross-bars 6, which cause them to move in unison. These movingbeams are supported by boxes 7, which inclose eccentrics 8, forming part of transverse shafts 9, driven simul-4 taneously by gearing 10 from a main shaft 11. The rotation of the eccentrics 8 by theshafts 9 imparts a rotative motion to the moving beams 5, causing them to alternately rise and lower, and in the part of their motion which is above the stationary rails 2 they move forward in a circular arc, the radius of which is the distance from the centers of the eccentrics to the axis of the shafts 9. Therefore any articles which are placed upon the rails 2 Specication of Letters Patent.

will be engaged by the moving beams 5 and will be moved forward step by step, being raised from the fixed rails, carried forward,

and then deposited thereon while the moving rails are describing the upper half of their circular movement and resting on the fixed rails while the moving beams are describing the lower half of their circular movement in a backward direction. The length of each step thus imparted to the articles by the moving beams is determined by the throw of the eccentrics, and the rapidity of the motion is determined by the speed of the driving-gearing.

The moving beams are provided with we aring-pieces 12, preferably of cast-iron, which afford transverse openings 13 for the passage of air, so that the beams themselves are pre- 7 0 vented from being overheated by hot articles which are being carried.

In Fig. 5 I show means for driving the main vshaft l1, consisting of a worm-wlieel 14 and vworin 15, which is rotated by a suitable motor 16 or some other power connection.

In Figs. 3 and A I show means by which the throw of the eccentrics can be varied to suit the requirements of the particular use to which the conveyer is put. of a disk 8, having an elongated slot 17 litting on a squared portion 9 of the shaft 9.

The slot is longer than the cross-section of the shaft andaffords room for the intel-position of liners 18. or more of the liners from one side of the shaft to the other the degree of eccentricity may be varied. The eccentric is held on the shaft and the shaft held in contact with the Each eccentric consists 8-0 By changing the position of one liners by a set-screw 19, set in a countersunk recess in the eccentric, as shown in Fig. 4.

In Fig. 6 I show a modification of the ap-l paratus in which the fixed and stationary rails are set on an incline, and for the, purpose of preventing the material conveyed thereby of moving beams and rotary eccentrics supporting the moving beams and arranged to' IOO impart thereto an upward motion and a forward motion above the fixed supports; substantially as described.

2. A conveyer comprising' a series of fixed supports for the material to be conveyed, a set of moving' beams, rotary eecentrics supporting the moving beams and arranged to impart thereto an upward motion and a forward motion above the fixed supports, a shaft 1l extending parallel with the moving beams, and gearing connecting the eccentrics ,therewith; substantially as described.

3. A conveyer comprising' a series of fixed supports, a set of moving beams, rotary eccentrics supporting' the moving beams and arranged to impart thereto an upward motion and a forward motion above the fixed support, and means for varying the throw of the eee-entries; substantially as described.

4. A conveyer comprising a series of fixed supports set in the same plane, and a set of parallel moving beams mounted on eccentries and adapted to have a rotary motion extraiding above and below the level of the lixed supports, said moving beams having iaengs provided with air-passages; substantialh' as described.

5. A conveyer comprising a series ol lixed supports set in the same plane, and a set of moving parallel beams mounted on eccontrics and adapted to have a rotary motion extending above and below the level of the lixed supports, said eceentrics being adjustable in throw; substantially as described.
