TIN-PLATE cn'ronnie.

Specification of Letters Patent.

Patented Nov. 26, 1918.

I '0 all whom it may concern:

Be it known that I, GEORGE L. ALLEN, a citizen of the United States of America, residing at 'Warren, in the county of Trum bull and State of Ohio, have invented certain new and useful Improvements in Tin- Plate Catchers, of which the following is a specification.

My invention relates to improvements in plate catchers suchas are ordinarily located on top of tinning pots in the manufacture of tin plates, and which can be used also for all like operations; and the objects of my invention are, first, to provide catchers which will receive the plates when pushed up from the tin pots and deliver them to a receiving and cooling table in perfectly fiat and even condition without warped edges or central waves or bends, and of uniform thickness; and, second, to reduce the cost by eliminating Waste and loss due to the production of uneven and imperfect plates called culls.

I accomplish those objects by the mechanism described, illustrated in the accompanying drawings and clearly pointed out in the claims.

In Figure 1, I show a conventional tin pot, in section, with my invention located on top thereof, in elevation.

In Fig. 2 I show my invention in perspective.

Like characters refer to similar parts throughout the several views in which P, represents a tin pot of any form, and in present practice .has a flux boX E, into which plates which are to be tinned are passed, and which comprises top and bottom aprons A, A, to guide the plates through molten tin T, up and between receiving rolls R, It, which rolls lie in oil floating on said tin and are operated by external mechanism, (not shown) so as to pass the plates up and out of the top of the tin pot P, where they are caught by the rollers 1, 1' and 2, 2, of my invention.

My rollers 1, 2, etc., consist of a plurality of pairs, operated as follows 2- A desirable number of rollers 1, 1, are rigidly attached to a shaft 3 which is rotated in any way, as by a belt over a driving pulley 4, and riding in bearings 5 in a supporting frame F, which is bolted or otherwise attached to the top of the tin pot, P.

As illustrated, a second rotating shaft 6 is supported by bearings 8, 8, attached to the frame F, and has a gear wheel 7 on one of its ends, which meshes with an idler gear wheel 9 sustained by the frame F, which gear 9 in turn meshes with a gear 10 rigidly attached to shaft 3. Consequently rotation of the pulley 4 rotates gears 10, 9 and 7 and shaft 6.

In the form of my invention illustrated, an inverted T-bar 11 is shown as bolted to the ends of frame F and parallel to the shafts 3 and 6. Any bar or equivalent sup port may be used.

To the under side of said T-bar 11, are fastened rigidly a plurality of hangers 12, 12 onsisting of a top and two parallel legs 13, 18, through holes in each of which the shaft 6 revolves.

Inside of said legs 13, 13' thereto are corresponding arms 14, 14 of a plurality of roller-carrying rockers 15, 15, having the rolls 2, 2 journaled therein between the tops of said arms 14, 14.

Springs S. S are connected to the adjacent faces of the rockers 15, 15 and the T-bar 11.

In line with rolls 1, 1, are the corresponding rolls 2, 2, each of which has an annular ring chamfered therein with gear teeth 16, 16 cut into the surface thereof.

Said teeth 16, 16 mesh with the teeth of gears 17, 17 rigidly attached to shaft 6.

In practice the tinned plates having passed up out of the tin-pot are caught between the rolls 1, 2 and 1, 2, which serve to lift them out and roll them on to a receiving table (not shown). The resiliency of the springs S, S, normally holds the rollers 1 and 2 and 1 and 2 together, respectively, but in instances of the passing through of plates of slightly varying and parallel thicknesses, or of warped contour, my rolls yielding, allow passage thereof by compression of the springs S, and in consequence do not squeeze, warp, wrinkle nor press the plates out of shape'nor change the straight edges of their evenly cut sides and ends.

I claim:

1. In a plate catcher of the kind described, a plurality of rollers located in independently and resiliently contacting pairs above the metal pot and sustained by a frameattached to said pot and actuated by a train ofgears, asshown and described.

2. A plate catcher having .a .plurality of gripping rollers on a single rotating shaft, and a plurality of cooperating gripping rollers each independently and revolubly mounted in a resilientrocker supported by a hanger, and actuated by gears, as shown and described.

3; A roller. for aaplate catching machine, having an annular channel in its periphery, and gear teeth therein below the level of its circumference.

4. A roller for a plate catcher, having gear 'teeth countersunk below its periphery and meshing with driving gears; a rockable support for the axle endsof said rollers; a

driving gear and a compression spring normally retaining said roller in contact with a cooperating roller on a non-yielding shaft.

5. In a plate catcher, a plurality of driven catcher rollers arranged in pairs, one rollero'f each pair revolving on a nonyielding shaft, and its corresponding roller revolving on an axle supported by a re ture in the presence of two Witnesses.
