To all 107mm. it may comer-a:

Be it known that I, NIoHoLAs CAMELO,

a citizen of the United States, and resident of Rome, in the county of Oneida and State of New York, have invented certain new and useful Improvements in. Sheet-Metal Plating or Coating Machines, whichflth'e fol lowing is a specification. j i Q My invention relates to machines for rapidly and uniformly coating sheet or plate metals or alloys with afilm or layer of coatbest known to me at present, but as will be apparent to persons skilled in the art to which my invention appertains it is susceptible to various changes in form and porportions and to Various desirable additions without departingifrom its spiritor sacrificing anyo'f its advantages. I therefore desire to have it understood that I include as hav ing produced'as new all such modifications as may be included within the scope o'f'my' V r -rollers and a sultablel. source of power and certain of the rollers maybe connected by appended claims.

In the draw1ngs I I 1. IS a side elevation of amachme constructed in accordance with my inven the frame carrying themeta'l wipers and showing the arrangementi'lor.operatlng SiLlCl wipers;

Fig. .6, an enlarged fragment ofythe machine showing the acid spray controlling mechanism ing metal or alloy, and it consistsjin im proved constructions, combinations and ar- Fig. 7,an end view of what is shown in Fig. 6; I Fi'g 8, a plan view of what. is shown in %ig. 9, an enlargedfragmentof the machine showing oneend of the metalreservoir and the means of controlling the ejection of metal therefrom;

Fig. 10, aplan view partly in section of a portion of what is shown in Fig. 9; and

F l ig 11, an end View of whatis shown in e'ferring now to the drawings in detail it will be observed that my machine includes a pair of sides 10 and ll formed of any desired material and design and suitably connected in spaced parallel'relation to form a supporting frame for the parts tobe described hereinafter. Preferably the upper longitudinal rails or bars 12 and 13 oi, the respective sides 10 and 11 are ar ranged at an incline so as to slope down-- ward fromwhat may be termed the front to the rear ofthe machine.

r-tdjacent the, front end of themachine and extending transversely thereacross, be-

tween the upper side rails 12 and 13, with their upper portions disposed somewhat be,

low the upper faces of said side rails, is a pair-0t feed rollers l4: and 15, and above and cooperatingwith these rollers, respectively, are rollers 16 and 17, which are journaled in suitable bearings carried by the side rails. A chain and sprocket connection 18 may be made between one of these or rs 19 whereby they will be caused toroin unison. r y Arranged transversely of the machine, in relative spaced parallel relation, between and connected .to the upper side rails 12 and 13,

spaces between these respective platform sectionsand also extending transversely of the machine, with their uppermost portions disposed ot'said platform sections are rollers 21. V

'Journ'aled ln bearings carried by the side substantially in the plane "or v slightly above the plane of the topsurfaces rails 12 and 13 and extending transversely across the machine, above and in spaced parallel relztifirm to each of 'iflerollers 21, 1s a shaft" 22, and longitudinally 'adg'justable on each of these shafts is a pair of 'scs 23,

4 4 gnu; ti-ve seller; 21,, Upon'oue Mn 'uf eaohlhl-it 22 is mounted a sprocket 24% 0nd, dam munner to be hereinafter described, these sprockets are suitably connecteG-M d'r' ive means whereby the several pairs of discs may ge rotated, said discs in cfilon with 'e rollers 21, and the rollers 14, 16, 15 and 17 constitutingthe means for feedingthe plates through themachine and over-the platform sections 20 upon which they *are supported durin their travel.

Rising from theru er faces of the respectiveside'rails I2 and 3, preferably at points in dllnementwith the first latform section 20, is a pair of blocks" an bridgingthese blocks 1s ajibbed "bar 26 which extends transv 'dfthe machine above said first platform section and in addition to termin a support for parts of the acid splay me anism now to be described indetail it acts a brace to vlend stiffness and ri 'dity theina'chine.

fillieacid spray mechanism includes a pipe 27 which extends transversely of the ma chine and roljects through openin I the blocks 25," 'e'in closed at {one end y a cap 28 and'at'its other end-beingextended as .c at 29"a'nd connected with an acid supply tank 30 located at any convenient point on or nearthe machine. I e lower ortionof pi 27, between the side rails and 13, is provifded'with a series of spaced openi s31 aha controlling the flow of acid fr in the ipe thro h these ,openings is a series o fseeves or co ars 32 whichare provided with openings ,33 and adaptedtc be rotated to aiine ordisaflinethe openings therein with the opening: in the pipe.

Brackets 34 are secured tcgjhe bar 26-and bear portions of' these brackets rotatably sup a shaft 85. latera'l'lywith respect to the bloc 25. At spaced alson this shaft are d a 36- and asfbes t own in Fig. lever arms are connected b lin'ks37 .w" h the respective cqllars32. artial rotat1on of the shaft 35 in one direction will result in a partial rotat' n of the collars 32 to aline the openinfi' and 31 and ,partial rotation of the am ,.in an opposite dissection will disalign said openings, asfwill be apparent.

Also fixed tp the shaftBfinear one end thereof, and extending downwardly from said Vsha'ft through a slot cut. in the adjacent side raihis a'lever arm 38. which, near,

itseitremity, is connected :to asu'itable'fixed portion inaehin by a contractile looil springv 39 which acts through theilever arm 38, shaft 35', lever armsBB links (37. to

.eaml'th the dimmer wardly'.dire'r';te lever arms" normally maintain the openings in the pipe 27 and collars 32 disaligned.

Pivoted at an intermediate point for retation in a substantially lateral plane is a Substantially L-shaped lever including arms being *bifm-camd to receive the rounded iterminailof lllhfl lever arm 38121211 thelatter beingisuitahlgshaped so that a ortion thereof will project into the part thheete A during their travel through the machine, as best illustrated in Figures 6 and 8. By'reference to the latter figure it will thus be observed that movement of the laterally rotatable lever in one direction will move the lever arm 38 against the tension of the sprin 39 in a direction to rotate the shaft 35 an through the links 37 to, rotate the collars 32 to aline the openi s 33 and A n air pump 42 is connected by a pipe 43 with the tank 30 whereby the acid in said tank may be forced into the pi e 27, said pump being driven-in any suita le manner as by means ofa belt 44 extending over a pulley on the crank shaft of the pum and over a pulley 45 on one of the roller s afts, for instance, as shown, shaft of roller 17.

It is believed that the o eration of the ants so far described wi 1 be apparent.

owever, it is as follows :A plate to be coated is fed into the machine between the pairso'f rollers 14-16, 15-17 which rollers force it alo over the first platform section 20. During-the initial art ofits movement through the machine theiforward edge of the plate comes in contact with the extremity of arm41 of the laterally rotatable lever'.and rotates this lever until its extremityl has moved out of the part of the plate w ich results in the collars being rotated to aline the qpenings 33 and 31 and permit the acid in the pipe .27 .to be ejected in a spray over'the plate, the side edge of the plate durirlg its continued movement riding against 1e extremity ofthe arm a1 and maintaini the openings 33 and 31 aligned until t e plate has passed entirely past the acid spray mechanism when the spring 39 will function to return the ;parts to normal position, disaligning the- openings 33, and 3 1 .and cutting off the acid spray until the forward edge of the next incomi plate contacts ,with the extremity of arm 41 and repeats the operation just recounted.

Immediatel .followan thepassage of the plates beneath the aci spray mechanism they are subjected to a wiping process to spread the-acid. thnroughly over their upper surfaceswhich acts ,asa, flux and cleans therefrom all foreign matter. Preferably this .wipingrmechanism located above the frame extends transversely of Jnanhine.

and is supportedfrom the upperside rails 12and 18 in any convenient manner. Bearings are provided within this frame at spaced intervals to rotatably receive a series of verticallyextending shafts 48, the upper portion of each of which is provided with a gear 49 meshing with the like gears of the next adjacent shafts whereby all of the shafts are driven in unison from a gear 50 on a vertical shaft 51 which latter receives its power from any desired source. A disc 52 is eccentrically mounted on the lower end of each shaft 48 and these discs carrybrushes upon theirunderfaces which wipe the plates as they pass beneath said frame.

After being sprayed and wiped the plates are fed on through the machine by the discs 23 and rollers 21 until they arrive beneath the mechanism for coating them, which mechanism is illustrated in detail in Figures 9, 10 and 11 of the drawings.

The coating mechanism, like the acid spray and wipersv previously described, is located over one of the platform sections 20 and consists of a tubular reservoir 53 arranged transversely of the machine and supported at its ends by brackets 54 rising from the side rails 12 and 13. The lower portion of this reservoir is provided with a longitudinally extending enlargement centrally cut away to provide a longitudinal channel 55.0pening into the lower face of said enlargement. Slidable in the channel 55 is a plurality of devices 56 and these are retained in the channel by plates 57 and 58 secured to the under face of the enlargement with their inner edges underlying the lower faces of said devices. An apertured device 59 projects downward from each device 56.

Abar 60 extends transversely of the ma chine below, parallel to and lateral of the series of devices 56 and is mounted for reciprocation in bearing brackets 61 secured to the respective ends of the reservoir. Rigidly secured to this bar is a plurality of spaced pins 62 which are respectively engaged in the apertures of the devices 59.

VThe devices 56, because of their connece.

tion with the bar 60, are movable in unison to cover or uncover a spaced series of openings 63 in the lower wall of the reservoir and in order that these openings may be uncovered and covered. at the proper times mechanism similar to that for controlling the ejection of acid from the ployed. i j r The mechanism referred toconsists of a vertically arranged lever arm 6% pivoted at its upper end to one end of the bar 60, pivoted intermediately to a'bracket 65 secured to the adjacent side rails and at its lower end engaged in abifurcated portion of a horizontallyrotatable lever 66 which is pipe 27 is em-v also pivoted at an intermediate point andhas one arm 67 thereof projecting into the path of travel of the plates to be coated. Connecting the arm 67 of lever 66 with a suitable fixed part of the machine is a contractile coil spring 68 which exerts an influence to move the parts to a position causing the devices 56 to normally maintain the openings 63 covered.

A tank 69 containing the molten coating metal or alloy is connected with the reservoir 53 by a pipe 70 and through any desired instrumentality maintains a predetermined amount of molten metal or alloy in the reservoir, and in the event the metal so contained becomes chilled or in order to pre vent it from becoming chilled, means in the nature of nozzles 71 may be provided for directing. jets of hot flame against the sides of the; reservoir to heat and maintain the metal therein at a uniform temperature.

The operation of the mechanism just described for supplying a coating of metal or alloy to the plates as they pass beneath the reservoir 53 is substantially indentical with the mode of operation-of the acid spray mechanism. During its movement through the-machine the forward edge of the plate to be coated contacts with and moves theextremity of the arm 67 of lever 66 until the devices56, uncover the openings63 permit ting the metal or alloy in the reservoir to flow throughsaid' openings and onto the plate passing therebeneath. A predetermined amount of'moveinentof the plate results in the extremity ofv arm 67 being moved out of the path of the plate after which it rides against one side'edge thereof and maintains the openings 63 uncovered until the plate has passed by when the coilspring 68 acts toreturn the parts to theirnormal position closing the openings 63 and in readiness to repeat the operation when the next plate moves in position to be coated.

Following their passage beneath the coating mechanism the plates are subjected. to a wiplng operation for uniformly spreading the coating material thereover and burnishing the, same. This wiping means is very similar tov the acid wiping means and consistsof. a rectangular frame extending'transverselyv across the machine and supported in any suitablemanner from the side railslQ and 13 above the platform sect-ions, said frame, as shown, including a pair of side bars 72 connected'at their ends by bars 73.

Carried by each .or the side rails 72 is a setof spaced bearings and rotatable in each of these bearings is a vertical shaft 7 4 which. at itsu pper end, carries a gear 75. Two separateseries'of gears and shafts are thus provided and as illustrated the several gears of'the first series as well as the several gears of the second series-intermesh. Preferably, however; there, does not exist any intermeshing relation between sthe respective series of gears, but the gears (of both series may 'be driven from a common source by a gear 7.6 on a vertiealshaft 77 .jounnaled in a bearing carried by one of the and bees $3. This igear Z6 with one of the pars 15 of each series and the shaft? canrying the same has fined to its lower end a bevel gear 78 which meshes with a similar gear 59 .on a short horizontal shaft 80 which is journailed in a bearingcanried by one of the upper side rails and at its outer end carries a sproeket 81 which may [be connected :to any desired source of power and rotation of which, as is apparent, will result in uniform rotationof all the shatts74.

A disc 82 is eccentrically mounted on the lower end of each shaft '74 and upon their lower times these discs carry brushes which wipe the upper faces of the plates as they pass beneath the rframe, ithe first series of brushes serving to wipe out the coating material to uniform vthickness and the second series serving to complete the wiping process as well .as burnish lates.

After passing heneat the wiping mechanism just described the plates are moved on byithe rollers 21 and discs 23to a'mechanism for scraping and trimming their edges. This mechanism consists of a pair of shafts 83tand 84,-the former extendingitransversely of the machine above the-plane ofithe'platform sections and the latter-eaten transversely of the machine ibelolw the p ne of the platform sections,-said shaftsbemg relatively disposed in parallelism and'preferably .in substantially relative vertical alignment. One end of one of these shafts has fixed thereon a sprocket 85 and both shafts, between the side :rails \12 and 13, have longitudinally adjustable thereon a pair of discs 86 having dine toothed peripheries or cutting edges. The discs of the two sha'its operate in pairs mud as the of the plates pass between them the teeth or cuttin edges {of the discs function to scrape n atrim the .edgesiof all surplus and inequalities in the coating material. Preferably adjustable bearings are provided 501' the shafts 83' and 8.4 sothat the distanoe between the discs 86mm be ivngied,but these hearings :may form the subject matter of a separate application and are JMOI'O not shown in detail. After passing between the edge scraping and trimmingdiscs the plates are ejectedfrom the machine lbyilthfl last-set of discs QBL nd roller 21.

If desired pans may :be ipnvidod beneath the acid spray and coating :menh "to receive any acid or coating matarialwhich might be delivered to the 1 letes in of the amount meded and hermoneccrtainof the collars 32,;anddevioes 56:may*be disconnected from their ,0 ing means and ithe discsi23 and 86 instead on .fllQll' imp shafts in order that plates ofvarimis widths may be coated by the machine without unnecessary waste of acid or of the coating material.

Power for rotating the various shafts of the machine may be applied in-various manner, but I prefer che sprocket and chain arrangement best shown in 1 of the drawings. I his =mangement consists of a pair of spaced stub shafts 87 and *88 extending laterally 6mm -oneside ofthe frame of the machine andieaeh carrying a sprocket 89 which sprockets are connected b a chain 90. Each of these shafts in adgitiop carvies a plurality of smaller and these latter are connected by chains 91 with the several slperoclcetsfi. A second sprocket on vone of t ahadtsfl is connected by a chain 92 with the'sproclcet 85 on ofthe edge scraping and trimmin carrying shafts and all of the spr ets with'their shafts are rotated from the sha 'ft of roller 17 :by means of a chain 93 teonnectin a sprocket 94 on -this shaft with a sp ct on the stub shait 87.
