Moore, Gary, Ind., assignor to American Sheet & Tin Plate Company, a. corporation of New Jersey Original application January 23, 1934, Serial No. 707,979. Patent 2,025,418, dated December 24,

3 Claims.

This invention relates to conveyors, and more particularly to feed-out conveyors for machines for processing metallic strip, such as shearing devices and the like, although not limited th reto, the present application being a division of my copending application, Serial No. 707,979, filed January 23, 1934, now Patent No. 2,025,418 of December 24, 1935, and bearing the title of Shear.

In my co-pending application referred to, a novel device is disclosed for shearing relatively long lengths of thin metallic strip and has among its objects the provision of an automatic apparatus which operates at a rate of speed which is materially higher than those of the prior art.

It is another object of the present invention to provide a novel conveyer which functions to remove metallic sheets from a metal-processing machine of any type in a manner which is both rapid and automatic.

The device of the present application is disclosed in the co-pending application referred to, but its utility is not limited to the art of cutting and shearing. It is, on the other hand, readily adaptable for feeding material from surfacing machines such as pickling or sand-blasting apparatus, tin or terne pots, metal-reducing apparatus such as cold mills, and various other installations too numerous to mention.

The foregoing and further objects will be apparent after referring to the drawings, in which:

Figure 1 is a side elevation of the device of the invention as it is used in combination with the shear of my co-pending application.

Figure 2 is a plan of the apparatus of Figure 1.

Figure 3 is a sectional View on the line III-III of Figure 1.

Figure 4 is an enlarged fragmentary sectional elevation.

Figure 5 is a detail.

Referring more particularly to the drawings, the letter A generally designates the metalprocessing machine from which the device of the invention is adapted to remove the metallic sheets. In the present instance the metal-processing machine A comprises a housing in which there is mounted a stationary shear-blade B. A rotatable shaft C is journaled in the housing A above the stationary shear-blade B and carries an eccentric D to which there is connected a connecting-rod E. This shaft C continuously rotates as long as the machine A is being operated, a shear-knife F being connected to the free end of the connecting-rod E for cooperation with the stationary shear-knife B. An electric motor G is disposed on the upper part of the housing A and arranged to drive the rotatable shaft C in any suitable manner. A conventional springactuated lifting device is employed to raise the Divided and this application November Serial No. 51,908

sheared sheets over the stationary shear-knife B, as shown. at H in Figure 5.

According to the teaching of the present invention, a frame 2 is disposed immediately adjacent the exit end of the metal-processing machine A and provided with suitable guide devices 3 extending from immediately adjacent but somewhat below the upper level of the fixed shear-blade B. A plurality of spaced-apart transverse members 3 are carried by the frame 2 for rigidly holding a pair of spaced-apart longitudinal brace members 5 on which a cross-head 6 may be moved longitudinally of the frame 2 toward or away from the metal-processing machine A and in perfect alinement therewith. The adjustable cross-head 6 is made up in part of a pair of rigid end supports i which are constructed and arranged for sliding engagement with the longitudinal brace members 5. The lower portion of the cross-head 6 is provided with a sleeve I which is screw-threaded at H. A pair of bearings l2 and 53 are connected to two of the spaced-apart transverse members 4 of the frame 2 in such manner as to rotatably support a shaft M which is screw-threaded over the major portion of its length. The screw-threaded shaft I4 is adapted to engage the screw-threads ll of the sleeve I 0 in such manner that upon rotation of the former the cross-head 6 will be adjusted upon the longitudinal brace members of the frame 2. A rotatable shaft I! is rotatably supported in suitable bearings carried by the right-hand transverse member 4 and carries on its end most adjacent the shaft M a pinion I9. The pinion l9 engages a similar pinion which is secured to the adjacent end of the shaft 14. The shaft l1 extends at right angles to the shaft [4 and is provided on the extremity of its adjacent end with a squared portion 2| to which there may be attached a suitable handle or crank (not shown).

The cross-head 6 carries a pair of elongated rotatable rolls 23 and 24 and a shaft 25 which carries a plurality of pulleys 25.

A sprocket I is carried by the shaft C on the metal-processing machine A. This sprocket 1 drives a sprocket 28 which is secured to a shaft 25 that is suitably journaled on the metalprocessing machine A through the medium of a chain 27.

The shaft 29 also carries a sprocket 30. A I

shaft 3| is journaled on the end of the frame 2 which is remote from the metal-processing machine A and carries a sprocket 32 which is connected to the sprocket on the shaft 29 by a chain 33. The shaft 3! also carries a plurality H of pulleys 34 which are equal in number to the pulleys 26 on the shaft 25. An endless belt 35 is disposed around and between each pair of the pulleys 25-34 on the shafts 25 and 3|, respectively. These endless belts 35 are disposed interframe 2 between the shafts 31 and 38 for guiding a vertically movable shaft 43 which carries 2 mediate the guide devices 3, which extend to the metal-processing machine A.

- The frame 2 supports a pair of spaced-apart transverse shafts 31 and 38, each ofwhich carries an idler pulley 40 for each of the endlessv belts 35. r V a A pair of vertical frames 42 are secured to the the cross-head 6 toward and away from the metal-processing machine A.

The elongated rotatable roll 23 on the crosshead 6 is spring-pressed downwardly, as'shown at 46, against those portions of the endless belts which are in contact with the upper portions v of thepulleys 2 6. 1

A .gear 41 is secured to one ,end of the shaft 25 and drives a gear 48 which is secured to V the adjacent end of the elongated rotatable roll 23. A sprocket 50 is secured to'the other end a chain 52.

of the roll 23 and which is secured to the gated rotatable roll 24 drives a adjacent end of the elonthrough the medium of IA shaft 54 is and carries a pair of spacedapa'rt and intermediately journaled levers 55 which extend transversely with respect thereto. One end of each of the'levers 55 extends to terminate immediately below the elongated rotatable roll 24 and gages a similar pinion the shaft 54.

*between these ends there is secured a shaft 56.

A suitable plurality of freely-rotating rollers 51 is carried by this shaft 56. The opposite ends of the levers 55 are weighted, as shown at 58.

A shaft is journaled on the frame 2 above but in parallelism with the shaft l4. This shaft 60 has secured thereto a pinion 61 which en- 62on the adjacent end of Thus; it will be seen that upon oscillation of the shaft'Bfl the shaft 56 will'be caused to raise and lower the freely-rotating rollers 51 which are carried by the latter.

Theend of the shaft 60 which is adjacent the metal-processing machine A is provided with a lever 65 which is connected by a link 66 to a,

similar lever 51 on' an overhead shaft 68.

Suitable sheet-flattening guides and sideguides 15 and 15, respectively, are disposed betweenthe metal-processing machine A and the the sheet-flattening guide 15 freely-rotating rollers 51 on the shaft 56. The metallic sheets being operated upon by the metalprocessing machine A are guided therefrom by and moved along the guide devices 3 on the frame 2.

Any suitable means may be employed for moving the metallic sheets S through the metalprocessing machine A, such as a gravity conveyer or the like, until they come into contact with a stationary stop 11 which is mounted on the cross-head 6. As the machine A continues its operation (whatever it may be), the shaft 60 is oscillated to raise the freely rotating rollers 51- into contact with each successive sheet and pinch it against the constantly rotating elongated roll 24.

In this manner the sheet is raised and disimilar sprocket 5 l' journaled on the cross-head 8 V nally extending guide means, a

rected between the constantly rotating elongated roll 23 and the constantly driven endless belts 35. The belts 35 feed the sheets onto a suitable rack (not shown). v In Figure 3 of the drawings the elongated roller 23 is shown as being covered with nonabrasive material 80to prevent scratching or marring of the metallic sheets S. .This is also preferably the case with the elongated roller, 24, and the freely-rotating'rollers 51 on the shaft 56. 7

According to the foregoing description it is readily seen how the operation of the metalprocessing machine A'raises the. sheet in contact with the stationary stop 11 on the crosshead 6 and conveys it vated endless belts 35.

The cross-head 5 may be easily adjusted with 7 respect to the machine A bythe'application of a I suitable handleor crank to the squared portion '2! of the shaft I1.

'In this manner, various lengths of metallic sheet may be handled bythe device of the invention.
