IvIAcHINE FOR CLEANING AND IAOLISQI-IINeI TIN PLATES.

SPECIFICATION forming part of Letters Patent No. 721,458, dated February 24, 1903.

l Application filed May 29, 1902.` lSerial No. 109,557, (No model.) I

To a/ZZ whom, it Vmay concern:

Be it known that we, WESLEY McCoRD and THOMAS GILL, citizens of the United States, residing at Lisbon, in the county 'of Columbiana and State of Ohio, have invented cerf tain new and usefulImprovements -in Ma chines for Cleaning and Polishi'ng'lin Plates; and we do hereby declare the following to be a full, clear, and exact description of the in; vention, such as will enable others skilled in the art to which itappertains to make and use the same.

Our invention relates to mill appliances, and has particular reference to an apparatus for cleaning, drying, and polishing tin plates after they come from the tin-pot in the course of manufacture, for the purpose of finally freeing them from oil or grease, and for polishing them prior to dusting and boxing.

More particularly stated, the invention,

which we term a branner, comprises mechanism forreceiving tinned plates from the tinpot of a mill, automatically conveying them into and through a body of bran, sawdust, or other suitable cleansing material, inverting said plates and conducting them similarly through a second body of cleansing material` for the purpose of removing all traces of oil or grease, and finally delivering them in polished condition uponva suitable receiving-table ready for packing. Y

The invention also comprises certain peculiarities of construction and arrangement of cooperating parts, modifications, and mechanical equivalents thereof, as will be hereinafter more particularly described, and pointed out in the claims.

In the accompanying drawings, which form part of this specification, and whereon corresponding letters of reference indicate same parts in the severalviews, Figure l represents a side elevation of our invention in position for operation. Fig. 2 is a front elevation of same from a point of view indicated by arrow 2 in Fig. 1. Fig. 3 is a top plan view of the mechanism complete; and Fig.'4= is a longitudinal section taken on the line 4l 4, Fig. 3, and showing by dotted lines the course of plates while undergoing the cleaning and polishing operation.

Reference being had to the drawings and letters thereon, A indicates the framework of our `machine, preferably of Wood and rectan-` gular in form, thoughobviously the material orl materials employed throughout, as also the form of construction, is wholly immaterial,

provided the mechanical functionsof the majchine are notinterfered with.

B indicates the curved bottom of bran- I ner, forming two independent semicylindrical cleaning chambers or compartments C O2, ex-

tending transversely from side t side of the series of'diskor wheelconveyers F', concentrically mounted with [relation to compartment C'and each provided with a series of radially-arranged operating-fingers G', said fingers of each particular conveyor traveling between one pair of thetracks D inthe course of each complete revolution ymade by the conveyers. y Similarly in the semicylindrical compartment, Czis rotatably mounted, as at c2 c2,`upon cross-shaft E2 a secondary series of conveyers F?, bearing radial fingers G2. By preference the individual conveyor-Wheels of the primary and secondary series are arranged in alinement, and consequently travel in corresponding vertical planes, although this arrangement is by no means essential to the mechanical and successful operation of the machine.

Upon one end of driving-shaft E is a iixed belt-p ulley H and an idler I, by agency whereof, together with a shifting belt, (not shown,) power Inay readily be appliedy to the machine at will of the operator. mechanism maybe substituted for` the pulleys shown, provided onlythat an" intermittent action may be obtained when desired. Upon the opposite projecting end of shaft E' and also upon the corresponding end of shaft E2 are secured sprocket-wheels cl e, respectively connectedby a sprocket-chain j, as the Obviously any clutch ICO means of transmitting power from one shaft to the other and imparting to the aforesaid primary and secondary series of conveyers rotary motion in unison and in the same direction, as indicated by arrows.

At front of the structure is pivotally mounted upon opposite sides of frame A a gage and guide bar J, which rising vertically from its points of support bridges the compartment C' above the primary conveyers F and is provided with a series of rearwardly-projecting downwardly-curved spring guide-arms K, in staggered arrangement with relation to the wheels or disks F, each of said arms bearing upon its under side a downwardly-projecting gage-lug g, as best shown by Figs. l to 4f. After adjustment the bar J may be firmly secured in its adjusted position by means of the segmental rack h and a suitable set screw or nut t', and it will be apparent from a description of operation to follow that the number and location of guide-arms K may be variously altered without materially impair-ing their usefulness. To the opposite or rear end of frame A is bolted or otherwise secured an inclined table L, having an upstanding end rail or stop j to arrest and retain the finished plates preparatory to boxing, and it will be particularly noted that said rail or stop jmay serve also in the capacity of a gage to regulate and determine the number of plates that should accumulate before removal by a sweep toward either unobstructed side. In like manner the stop j may, if desired, be made adjustable in height and provided with a graduated scale for the purpose of actually counting the plates and automatically bundling them in accordance with their gage, weight, or size and the standards prevailing as to number of sheets to the box.

The use and operation of this invention is substantially as follows: Tin plates as they come from the tin-pot still warm in the course of manufacture are introduced into the cleaning and polishing machine at its front end, where they are engaged by fingers G' upon the revolving primary conveyer-wheels F and forced down through a body of bran or analogous cleaning and drying material contained in the compartment C'. Taking the course indicated by the continuous arrow in Fig. 4, they are next elevated until their advance edges impinge upon the under side of guides K, surmounting said primary conveyer F', and are conducted thence to stops g, by which they are arrested. At thatinstant, springing clear of the curved central projection b on tracks D, the plates fall by gravity onto a set of fingers G2 of revolving secondary conveyer F2 in an inverted position and are similarly conducted down and through a second body of dry bran or similar material contained in the compartment C2. Rising thence as indicated by the continuous arrow aforesaid, the plates emerge from the machine thoroughly cleansed, dried, polished on both sides, and straightened, whereupon, overbalanced by their own weight, they fall onto the receiving-table L, ready for dusting and boX- ing.

Having thus described our invention, its use and leading points of advantage, what we claim, and desire to secu re by Letters Iatent, is-

l. In a machine for cleaning and polishing metallic plates the combination with a clean-v ing-chamber containing curved guide-tracks, of a rotary conveyer concentrically mounted with relation to said tracks, radial fingers upon said conveyerf for coperating with the tracks aforesaid to advance plates through the cleaning-chamber, and a suitable stop surmounting said conveyer for arresting the plates and delivering them from the conveyer, substantially as specified.

2. In a machine for cleaning and polishing metallic plates the combination with a cleaning-chamber containingcurved guide-tracks, of a rotary conveyer concentrically mounted with relation to said tracks, radial fingers upon said conveyer for coperating with the tracks aforesaid in advancing plates through the cleaning-chamber, and a series of surmounting adjustable stops for arresting the plates and delivering them from the conveyer, substantially as specified.

3. In a machine for cleaning and polishing metallic plates the combination with a primary cleaning-chamber and conveyer, of a secondary cleaning-chamber and its conveyer and a series of adjustable stops surmounting said primary conveyer for arresting the plates and delivering them from the primary to the secondary conveyer, substantially as specified.

4. In a machine for cleaning and polishing metallic plates the combination with a primary cleaning-chamber and conveyer, of a secondary cleaning-chamber and its conveyer, and a series of adjustable stops surmounting said primary conveyer for automatically transferring plates from one conveyer to the other, and for inverting them at the instant of such transfer, substantially as specified.

5. In a machine for cleaning and polishing metallic plates the combination with a cleaning-chamber, of primary and secondary conveyers rotatably mounted in said chamber, guide tracks underlying said conveyers, guide-arms surmounting the primary conveyer for directing the plates in their course, and a series of adjustable stops surmounting said primary conveyer for arresting the plates and delivering them in an inverted position to the secondary conveyer, substantially as specified.

6. In a machine for cleaning and polishing metallic plates the combination With a cleaning-chamber, of primary and secondary rotary conveyers comprising a series of independent wheels or disks mounted upon a shaft common to each series, underlying guide-tracks arranged in pairs, a series of guide-arms surmounting said primary con- IOO IIO

Voyer-'Wheels and arranged in adjacent vertical planes, and a series of adjustable stops adjustable stops for arresting said plates and delivering them in an inverted position to the secondary conveyer, anda suitable table upon which the finished platesare automatically delivered by the secondary conveyer, substantially as specified.
