MACHINERY OR APPARATUS FOR CLEANING TIN AND TERNE PLATES.

SPECIFICATION forming part of Letters Patent N 0. 428,994, dated May 27, 1890.

Application filed July 12, 1889. Serial No. 317,354.

To all whom it may concern:

Be it known that I, JAMES ABBOTT, a subject of the Queen of Great Britain and Ireland, residing at Blaina, Kingdom of Great Britain and Ireland, have invented new and useful Improvements in Machinery or Apparatus for Cleaning Tin and Terne Plates, (for which English patents, No. 7 ,366, May 3, 1889, and No. 10,116, June 21, 1889, have been obtained,) of which the following is a specification.

This invention relates to the operation of cleaning tin and terneplates by dipping them in bran for the purpose, as is well understood, of removing grease remaining upon them after withdrawal from the grease-pot.

This invention consists, first, in a method of and means for mechanically cleansing both sides of the plates by passing them through two troughs in succession, each trough containing bran and placed one behind the other. The plates are mechanically passed through the front trough and transferred therefrom to the second or rear trough. They are reversed or turned over at the time of transfer.

In Figure 1 of the accompanying drawings is shown aplan of apair of troughs a, arranged and fitted for cleaning tin and 'terne plates in accordance with this invention. Fig. 2 is a vertical section. Figs. 3 and 4c are similar views to Figs. 1 and 2, respectively,illustrating a modification.

Referring to Figs. 1 and 2, in each trough are three sets of forked arms 0, each set being mounted at suitable distances apart on a shaft 1), carried in bearings at each side of the trough. At one end each shaftl) is fitted with a toothed wheel to, gearing with the pinion y, driven by thepulley Y, keyed on (No model.) Patenteclin England May 3, 1889,110. 7,366, and June 21, 1889,N0.10,116-

the shaft 5. Each trough a contains bran, the upper surface of which is roughly indicated bythe dotted lines at, Fig. 2. Each plate p on entering in proper turn the front trough is received in a bend of the forks c, of which three are presented thereto abreast. By the forks the plate, which is kept raised by guides (Z, is lowered to the bottom of the trough, from which point it is forced upward through the bran to the dentated tilting table j, which normally lies in the position indicated in dotted lines, Fig. 2, and is carried on most which was downward in the first trough.

On arriving at the rear end of the second trough the plate approximately uniformly cleansed on each side is tilted by the dentated tilting table f onto the shelf h. The rack by which the plates are fed to the first cleaning-trough consists of a skeleton drum having radial arms 1' springing from a spindle j, carried in bearings, as shown. Upon these radial arms are laid the plates 1) to be cleaned.

Those forked arms 0 which are situated toward one side of the front trough are furnished with strikers 7r, Fig. 1, which as the arms rotate strike in turn against the bent arms Z fixed to one side of the rack, which latter is thus caused to rotate and to discharge into the trough the plate lowest in the rack. The rack is prevented by the spring m, acting on the recessed pinion n,from-rotating at one time farther than is required to deliver one plate into the trough.

Figs. 3 and at show a modification of this invention, under-which the plates for cleaning are seized between spring-jaws and drawn through the bran, instead of being thrust through it, as in the arrangement first above described. On the shafts h, driven by suitable gearing, are keyed the arms 0, which retate in the troughs a. as the shafts I) revolve. At each extremity of each arm 0 is a jaw composed of a rigid member (Z and a member (1', capable of turning on the spindle '1', which connects all the jaws in each separate parallel series. By springs c, fixed to the arms 0 and bearing against the hinged members of the jaws, the latter are normally kept closed. Pivoted in brackets g situated toward the rear of each trough, are levers 7, having fingers Z extendinginward-that is to say, transversely to the longitudinal axis of the troughs. The levers Z, which toward their tail have curved projections 7 lie normally in the position indicated in dotted lines at Fig. 4:. At the front end of each trough, at each side thereof, is a curved bar 71 so situated relatively to the center of the shaft 1) and the spindle t that the latter, when brought into contact with the bar 71, is thrust outward, and the spring a, being thus depressed by the pivotedmembcr (Z of the jaw, the jaw is opened. Into it is inserted the plate 17, which is gripped by the jaw as soon as the spindle 1 passes clear of the bar h. Assuming now that a plate 1) has been inserted in the jaw at the front of the leading trough it (the plate) is drawn through the bran, the surface of which is roughly indicated by the dotted line a, Fi g. -l, as the arms 0 rotate with the shaft 1). On reaching the rear end of the front trough the levers Z thereat are tilted by the spindle i against the stops g, formed 011 the brackets g. The arms continue to rotate, and when the spindle '21 is brought into contact with the raised part Z on the levers the springs e are overcome, the jaw is opened, and the plate 1), directed by the levers l and fingers Z, drop into the jaw on the arm (2, presented for its reception at the front of the rear trough.

\Vhen the spindle of the jaw from which the plate drops has passed the projections Z on the levers l of the front trough, the said levers swing back to their normal vertical positio 1. The plate now delivered to the rear trough is carried through the bran therein (indicated by the line at, Fig. l) in the same manner as in the leading trough, but having that face uppermost which in the first trough was downward. The plate is released and discharged onto the delivery-table 75 by similar means to those by which it is transferred from the front to the rear trough.

\Vhat I claim is- 1. In a machine for cleaning tin and terne plates, the combination, with two cleaningtroughs, each to contain bran or other cleaning substance, of sets of revolving arms, each adapted to receive and pass a plate through one of said troughs, and a transferring device located between said troughs and adapted to automatically cause a plate to pass from one set of arms in the first trough to another set of arms in the second trough, said device being operated by the firstmentioned arms, substantially as herein described, for the pur pose specified.
