To all lwhom it may concern:

Be it known that I, W'ILLIAM WALLACE SHERwooD, a citizen of the United States of America, residing at Grand Rapids, in the county of Kent andState of Michigan, have invented certain new and useful 1mprovements in Painting, Varnishing, Or Coating Machines; and lV do hereby declare the following to be a full, clear, and vexact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a painting, coatingv or varnishing machine by means of which paint, varnish or other coating material may be transferred' from' receptacles which hold the coating material to an article which is to receive the coating. It is an object and purpose of my'invention to feed fiat material to the machine and applyv the coating or varnishing liquid to this ma# terial on both sides thereof. A further object of the invention' consists in the provision of upper and lower rolls to transferv the coating fluidto the material, said lower rolls being adjustable with respect to a supporting frame which carries all of the rolls so that the machine may be used for various thicknesses of material. Further objects and purposes of the invention consist in the provision of many novel and useful features of construction and operation which will more fully appear upon understanding of the construction of the machine which embodies the invention disclosed in the accompanying drawings, in which: v l

Figure 1 is a front elevation of the machine. Y

Fig. 2 is a plan view thereof. y

Fig. 3 is a view from the left of the machine shown in Fig. 1. j

Fig. 4 is a sectional detail viewl of the driving mechanism for the machine.

Fig. 5 is a view'similar to Fig. 3 from the opposite end of the machine; and o Fig. 6 is a` detail'end elevation showing one of the transfer rolls and the means used to remove the excess of coating' material thereon.

Like reference characters refer to like parts throughout the several views ofthe drawings.

In the construction as disclosed, spacedV apart supporting frame members 1 kare provided connected at the front and rear adjacent their vlower ends by cross beams 2. A

short distance above the cross beams rodsv 2*" are also interposed between the frame `membersA 1 to strengthen and reinforce the frame. At oneend a frame member 1 carries an auxiliary support which is located in upright position parallel to the frame member 1 being supported at its lower end by spaced apart brackets 4 which are bolted to the member 1.

. A distance above each cross beam v2 a horizontal member 5 is located and is adjustable toward vand fromthe cross beam directly below it by means of screws 6 which are adapted to be manually operated by the hand wheel 7 Vertical supports 8 arcsecuredv t0 and lie between the members 5 adjacent the ends thereof andextend upwardly a distance toserve as supports for shafts 9, two of which are carried by thel members 8l ink suitable bearings, each shaft havingthereon a roller 10, the outer surface of whichv is formed of any'suitable composition material. Below each roller 1Q is positioned 'a pan 11 which serves as a-receptacle to vretain paint, varnish or other `suitable coating materiahrollers 10 operating in and turnino'through this iiuid. The pans 11 have adjacent edges coming'together and are supported at their ends bythe oppositely extendingarms 12, one pair at each end being carried at the upper end of an upright 13, vwhich at its lower end is formed integr'ally with a block 14 slidably mounted between guides 15 Vbolted to and suspended from the supports S. A screw 16 is threaded into each block' and extends downwardly carrying at its` lower end a bevel pinion 17 which meshes withsimilar pinions 18 secured on a shaft 19, supported by brackets 20`cast integral with the guides 15 hereto-v fore described. 'Shaft 19 may be operated by the hand wheel 21 and it is apparent that on operation of this wheel the pans llare raised lor lowered with `respect to the rolls 10 so that they may be removed at any time for any desired purpose such as cleaning and the like. It is also evident that the entire structure is movable with the bars 5 whenever such barsare raised and lowered as previously described. Each roller 10 has j mounted adjacent its outer surface a scraper 22 which extends the full length of the roller has passed through the l'coating fluid, "by properly locating the Scrapers 22, asmuch of the fluid may be removed as desired so that a smooth and even coating without eX- cess material may bezretained .bythe rollers 10.

"Directly vvabove shaftsll on eachy of Vthe frame members 1 are bearings 26 in which are mounted shafts 27 carrying composition rolls 28 located directly above and vspaced a short distance from the rolls l0 heretofore described. Each ofv the composition rolls 28 has a roller 29 mounted alongside it, these rollers being preferably of cast iron and either cast integral or secured toshafts 30 which are mounted at their ends Von suitable uprights 3l which are secured to a platev 82 at its ends slidably mounted on guide ribs 33 connected to the end frame members 1. Adjacent each yof the members 3l a bracket 34 is secured ito and above each end frame member l being formed at its upper edge with a rack 35 vwith which meshes pinion 36 attached to a, shaft 37 which is mounted in suitable bearings adjacent each end in the parts 3l heretofore described. A hand wheel 38 is attached to one end of the shaft and it is apparent that on manual operation of this wheel ay roll 29 may be ymoved' toward or from its associated vroll28 so as to- Contact therewith with any desired degree of;`pres sure. Clamping devices 32'd are used to hold the roller 29 in anyk position to which itv may bemoved.

Underneath each roller 29 a-pan 39 is locatedhaving adjacent one edge a plurality of hooks 40 adapted to engage' with pins 40a projecting from a relatively stationary transverse member 42. Adjacent its opposite edge veach pan is provided with afpin 4l'whic'h may be set in any suitable socket to hold this side of the pan in place. 'The klpanVv is i'illed with any suitable coating liquid and roller 9 passes therethrough. A plura'lity'of spring fingers 43 are attached at one end to the cross bar 42 and at their opposite ends have blocks connected to theirun'der faces in'wh-ich is seated a scraper 44A extending the entire ,length of a bearing against the roller 29.` Pins 45, one'for each member 43 project from the bar 42 and pass through saidmembers 43receiving at their free en'dsfnuts 46. Between the bar 42 and f each 'member 43 a compression spring 47'is located around each pin 45, it being evident i,

from this construction that the scraper 44 may be pressed against its rollerv29 with as greator little pressure as desired so` as to vremove* any eXcess'of coatingmaterial col lccted thereon and as the roller 29 bears against an adjacent roller`28 what coating material isnot scraped from it by scraper 44is transferred to the roller-28. Asyplat- V"form 48 is positioned between the Vframe members l at the frontend of the 'machine 'the'lower edges of the rollers 28. Material whichlisrtorbe-coated isfzlaid'fon this platform and fed between the rollers 10 and 28, and it will befevidentthat coating or varnishing material will be transferred from thesef'rl'lers to the material fed into the machine and whatpart is not coated by the 'first pair of rolle'rs`10 and 28 will be conipleted by the seconlrpair. f

The mechanism .ifor driving the rollersy will now be described. Adjacent the lower edge ofth'e .b'racketB ya Vbearingisformed which carries a short shaft 49 on'the outer end 'of which l is l`looselyr mounted L idrive wheel 50 while its inner end has a pinion 51I fastened thereto. fBet-ween the drive* wheel 50 andthe frame member 8, a clutch member 52 is splinedto shaft 49 having diametrically opposed pins'v' projecting therefrom toward.. the drive wheellO. Similarly opposedpinsl 54project from the drivewheeltowardthe clutch'member 52. A'leverf ispiv'otally mountedbetween its ends on.. a bracket 5 6 and at its lower ends is forked at 57, they member of the yfork passing to either side of the'clutc'h member 52V and engaging therewith. Byoperating lever 55. the clutch lmember may be moved toward the drive wheel so that pins 58 and l54 engage in'this manner v.im

which has connection by two universal joints'GOandfGl withfone of the shafts 19 heretofore-described. VDirectly above gears shaft projecting therefrom and connecting at its endsas illustrated v'at (3S-with the end of a shaft 27 heretofore described. gear 62'als`o meshes with a smaller gear 64 mounted immediately infront, each of these" .gears havingconnectiou through the Ytwo universal joint' /connections' -andf6`6 with v a lshaft 30 previouslyV described. The va" ri'ous unive'rsaljo'int connections shown and described j'iermit"theladj'ustment of they roll# ers 10 and'f29 with respect'tothe rollers' 28 withoutinterfering` with `theV continuousi drivingthereof no "matter in which position they are left.

From the foregoing it willlbe apparent that I have: provided a machine which can be used to paint ortvarnish orV otherwise coat material with great' rapidity both sides" Each 59 are gea-rs'62 which mesh therewith being. suitably mounted on short shafts on they frame memberB. vEach gear 62 has ashort vri ia thereof being coated at the same time. 'This i is 'ofespecial value in varnishing'or coating panels'which'may beV of Vmetal'or-'wood vor fiber 'or otherlikematerial. Of course itis apparent that one side only of a panel may be coated if desired by merely leaving the coating material out of either pans 11 or 39. Many changes in detail of structure may be resorted to without departing from my invention which is defined in the appended claims. Accordingly I do not wish to be limited to the exact disclosure of the invention but consider myself entitled to all modifications of structure falling within the scope of the claims which define the invention.

I claim 1. In combination, spaced apart supports, a vertical member positioned adjacent each support, means for raising and lowering said members, a pair of spaced apart rolls carried by and between said members, a roll mounted above each of the first mentioned rolls and carried by said spaced apart supports, and a pan partially inclosing the lower part of each of said rst mentioned rolls, said pans being supported by and movable with said vertical members.

2. In combination, spaced apart supports, a vertical member located adjacent and on the inner side of each support, means for raising and lowering said members, a pair of spaced apart rollers carried by and between said members, a pan being carried by and movable with the roll supports, and means for independently moving said pans with respect to the rolls.

3. In Combination, spaced apart supports, vertical members located one adjacent each support and mounted for vertical movements thereon, a pair of rolls mounted in spaced apart relation between said members, a bracket having oppositely extending arms mounted for vertical movements on each member, and a pan carried between each pair of arms adapted to partially inclose each roll at the lower part thereof, substantially as described.

4.
