Application led J une 16, 1914.
T) @ZZ whom it may concern Be it known that I, Pliner BRAINE TAY- Lon,`a subject of the King of Great` Britain, and resident of Middleton House, Briton Ferry, South lVales, have invented new and useful Improvements in or Relating to Machines for Branning, Cleaning, and Dusting Plates Coated with Tin, Terne, or other Metal or Alloy, of which the following is a specification.
This invention comprises improvei'nents in or relating to machines fo-r branning, cleaning and dusting plates coated with tin, terne, or other metal or alloy. As is well known, the plates, after being coated by dipping, are passed through finishing rolls which revolve in, for example, hot palm oil. Consequently the plates leave the rolls in such condition as to necessitate the removal.
of the grease with which they are found to be covered. For this purpose the plates are inserted into a branning or cleaningmachine in which they are treated with bran or the like and robbed of their grease by the action of the cleaning medium employed. They are finally treated by cleaning or dusting apparatus.
rlihe object of the present invention is to secure improved working conditions with an absence or minimum of dust emission and to obtain a better finished plate without complicating the branning apparatus or rendering` the same costly.
According to this invention the branning machine comprises an inclosed branning chamber containing` or combined with a dust-raising or circulating device for bran or other cleaning material, the said device being adapted to disperse into the atmosphere of the chamber particles of cleaning material so that the plate to be branned is enveloped in a dusty atmosphere the dust from which settles upon and becomes attached to the surface of the inserted plate which thereby becomes thickly covered. rllhc device may comprise a suitable agitato-r, or rotary distributer, or a pneumatic circulator, such being examples of suitable apparatus for creating and maintaining a dusty atmosphere within the chamber. rlhe greasy plates which are suitably conducted to the branning machine from the finishing rolls aforesaid are introduced into the chamber through a suitable aperture, with either a short or a long edge in and it is Specification of Letters Patent.

arranged for a suitable time interval to elapse between the introduction of the plate and its seizure by certain feed rolls so that deposition of dust and cleaning material may take place on both surfaces of the plates. Thereafter the plate may be cleaned of the bran deposit and the grease which has been taken up or absorbed by the same.
The invention is thus distinguished from a previous proposal to blow jets of cleaning material against the surfaces of plates to be cleaned, or to cause such material to be applied directly to the surfaces by centrifugal devices, the material being circulanted by a fan adapted to withdraw the material after use and return it to a feeding hopper or the blowing jets. In such previous cases the covering of the plates was not due in any way to dispersal of the material into the atmosphere of the chamber but to the direct impelling of the particles on to the plates. Moreover in these previous arrangements only a small portion of the plate was being branned at any given moment.
In carrying out the invention the plate may be passed by means of a chute or other conveyer through the inclosed chamber wherein is freely circulated the bran or other cleaning material as aforesaid. The material is caused to be thickly sprinkled over the whole surface of the plate on both sides, and it is only after such thorough treatment with cleaning material and the lapse of suiiicient time for same to absorb the grease, that the cleaning of the plates by rollers, brushes or other means takes place.
The branning machine may be arranged at the back of the tinning machine, so that the coated plates may pass directly into the branning machine from the delivery apparatus of the tinning machine.
In order that the invention may be read ily understood reference is made to the accompanying drawings in which Figure 1 is a sectional elevation of one form of apparatus made according to this invention. Figs. 2 and 3 illustrate modified forms of devices for preventing escape of dust from the eXit opening of the chamber. Fig. 4: is a diagrammatic view of a chamber having two mechanical dust raising devices and Fig. 5 is a diagrammatic view of a machine using a pneumatic jet apparatus in place of the mechanical devices for raising and circulating the bran. Fig. 6 is a diagrammatic view of a modified construction comprising an endless conveyer within the casing. Fig. 7 is a side elevation of aportion of the casing fitted with adjustable dust proof bearings.. Fig. 8 is a sectional view 'of a bearing fitted with a dust protector.
Fig. 9 is a diagrammatic view of a modified construction comprising a blower and pipes cover Z9, a slot or aperture 0 being left at one Side forY the introduction of the coated plates, which latter may be fed to the aperture c Vby hand,`or by any suitable conveyer or chute. From the inner side of the slot or f aperture c a wire chute or slope d extends to the first cleaning 0r feeding rollers e c. The chute or slope d may be in two sections the 'lower one of which may be inclined less steeply than the upper one, as shown. The
sections may be connected or made in one piece as shown'in the drawing. The clean- A ing rollers e e are revolved slowly and are designed to slowly conduct a plate from the n wire chute d to the nip of a pairof feed rollers f f revolving at a higher speed. The
rollers f f conduct the plate to another pair of feed rolls g g revolving still faster, a second pair of cleaning rollers it It being interposed between the two pairs of feed rollers ff and g'fg and .revolving at a speed greater than the rollers; f f and less than the'l rollers g g. Other combination of brushes only'or brushes and feed rollers may be employed and are preferablyl arranged all of increasing speed from entranceV to exit end of machine, after the known manner of arranging a series ofdriven pairs of dusting rollers in a dusting'machine. In some cases it may be found advantageous for the diameter of the rollers of the second pairfof cleaning rollers to be greater than the diameter of the first pair. A
The plates are delivered bythe feed roll- Vers 'g grthrougha slot or mouth-piece i. The =various rollersand the mouthpiece may as shown be so arranged asl to Vgive the plate a Y, curved and .upwardly directed path. The
inletand'delivery slots Vare both preferably .designed to preventV escape ofrdust and, as
an additional precaution two flaps jef leather for other suitable materialbacked with rubber 7c, or such like flexible material,
maybe arranged 'on the outer side of .the delivery aperture A hinged or flexible V i flap VZ may also be arrangedV within the entry j slot ornaperture, ifn'e'cessary.- These flaps 'Y Y press 4'lightly upon the .plate making its entry or exit, and, when no plateis passing, the
flaps cover their respective slots and prevent leakage of dust. If desired, a selfclosing flap fm., as shown in Fig. 2, may be employed on the exit end; or brushes n a may be substituted for the flap, as shown in f Fig. 3. These flaps are advantageously made in short sections so that no more of the aperture is exposed than is demanded by the size of plate being cleaned. Flaps have been used heretofore however for guarding the entrances .and exits of branthe chute cl and adheres to the lower surface of the plate. Y The cleaning rollers c and 71, also'become covered with the falling material. Between the moment that the plate enters the chamber and the moment that it is taken hold of by the first feed rollers f from the first pair of slowly revolving cleaning rollers e, sufficient time elapses for an v efiectivevdeposition of dust to take place on the plate and for the dust so deposited to absorb the grease.
As soon as the plate enters the nip of the first pair of feed rollers f, the said plate will travel .at a speed greater than the peripheral speed of the cleaning rollers e and the latter, owingQto the differential speed, will act to clean the surfaces of the plate. A similar action will take place during the passage of the plate between the second pair of cleaning rollers 7L. An outlet opening p for the bran may be provided as shown in the bottom of the chamber, and such opening may be closed by any suitable cover f/v. It will of course be understood that the Aplate need not be bent at all during its passage through the branner, but the feed rollers and cleaning rollers may be so arranged that the plate may pass through them in a straight line, this arrangement being particularly suitable when thick plates are to be cleaned. v
`It may be found necessary or advantageous in some cases to employ a traveling conveyer in place of the chute (i las shown in Fig. 6 which would have the advantage that the speed with which the plates are conveyed to the cleaning brushes could be made suliiciently slow to insure a thorough coating of bran being deposited on the plates. It may further be found advantageous in some cases to employ a single conveyer cl2 to carry the plates from any convenient point outside, into the chamber and if necessary through the chamber a, right up to the cleaning and feed rollers as shown in Fig. 10. However conveyers have been used hleretofore for feeding plates to and through branning boXes and chambers.
The cleaning rollers of the branning machine may be of bristle, horse-hair, felt,
sheepskin, or other suitable material and preferably the rollers of any pair are driven at differenti speeds, so that they clean one another when no plate intervenes. It may also in some cases be found advantageous to employ endless bands carried by pairs of rollers and covered with bristles, sheepskin or other suitable material in place of single rollers or brushes. Fliers, or wire or other brushes or other suitable means may be provided and arranged so as to scour the cleaning rollers, and scrapers or brushes may also be provided to keep the feed rollers free from cleaning material, these scrapers being advantageously arranged in the form of guards w to protect the feed rollers as shown in Fig. l.
lllhen the feed rollers comprise rubber or like disks, the disks of a pair of rollers may vbe arranged so as not to come opposite one another so as to aid in cleaning such rollers.
The bearings of the rollers are advantageously dustproof and adjustable. For eX- ample as shown in Fig. 7 springs m may be arranged to constantly tend to force the rollers of a pair apart, and adjusting screws or bolts y/ being then provided for regulatingthe relative positions of these rollers, the spindles of which are journaled in blocks e moving in guides l. Alternatively the casing containing the cleaning material and inclosing the agitator or distributer and brushes may be constructed as shown in Fig. 8 so that the spindles project through same into bearings 2 arranged on the outside of the chamber, thus keeping the bearings clear of dust.
In place of a revolving or mechanical agitator in the branning chamber, perforated or slotted pipes or nozzle discharges 4, as shown in Fig. 9 may be used and the bran or other material forced through the perforations of such pipes or through the nozzles by means of a blower or fan 5 the perforations or nozzles being so formed or arranged in every case as to disperse the material in the atmosphere of the chamber as described above. The blower or fan may suck bran from the bottom of the branning chamber and deliver the same to the upper part thereof. A single fan or blower may be employed for circulatingjhe bran in several chambers.
lf desired, more than one agitator or distributer may be provided in the branning chamber and where two or more agitators or distributers are employed these may be arranged, as shown in Fig. d, to throw the bran or the like over the front and back ends of each plate u as it moves down the chute al and thus supply a greater amount of cleaning material to the plate.
A further alternative consists in the employment of pneumatic jet apparatus, or pneumatic conveyers. Such jet apparatus may be of the form shown in Fig. 5 and comprise the ejector nozzle arrangement r for picking up the bran from the Hoor of the chamber a and conveying it through a conduit s to a suitable delivery nozzle t for delivering the bran or cleaningimaterial into, and dispersing it within, the chamber c as shown. ln the case of blower, fan or pneumatic apparatus the discharge pipes within the chamber may be arranged both above and below the plate and not only unl derneath as shown in Fig. 5.
In .any arrangement according to this invention the plates are passed through an atmosphere laden with dust or particles. This necessarily implies dispersal of dust or particles into an inclosed space, as distinct from a concentrated jet of dust or particles directed on to the plate at one point only and it also necessarily implies dust or particles inflight or movement and borne on a fluid medium as distinct from a mass of bran or dust in which latter oase the particles rest upon and are supported by one another, the lowerrnost particles resting upon a rigid bottom or support.
In all cases provision may be made for rendering the interior of the brauner easily accessible and this may consist of a hinged lid or cover of ordinary form as shown in Fig. l or the top of the casing may have a cloth covering which may be arranged to roll up after the manner of a roller blind'.
When using the machine for thick or es pecially heavy coated plates a fan blast may if necessary be arranged in a convenient position so as to cool the plates prior to branning.
If desired, hoppers may be arranged to feed the cleaning rollers with bran or cleaning material. Also it may be arranged for these hoppers or other suitable receptacles to be automatically fed with bran or cleaning material. For example lthe hopper o shown in Fig. l may be provided and will be so fed and the agitator or distributer will feed the hopper to a greater extent during the intervals elapsing between the exit of one plate from the branning chamber and the entry of the next plate. Obviously, if desired, the plates may be passed successively through say two branning chambers containing identical or dis-similar agitating and cleaning arrangements.
While brush or other feed rollers may in special. circundantes be employed at the rentrance to the inclosed chamber it is par- Wticularly desirable that they be omitted wherever possible so as to thoroughly coat the plate all over with cleaning material prior to passing between any form of cleaning or feed rolls. I do not confine myself to the form of chamber shown.
