CLIFTON F. LEATHERBEE, OF NEWTON, MASSACHUSETTS, ASSIGNOR TO PAINTING MACHINE COMPANY, OF KITTERY, MAINE, A CORPORATION OF MAINE.

WOOD-TREATING MACHINE.

Patented May 23, 1916.

Application filed August 17,1909. Serial No. 513,240.

To all whom it may concern:

Be it known that I, CLIFTON F. LEATHER- BEE, a citizen of the United States, residing at Newton, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Wood- Treating Machines, of which the following is a specification.

My invention relates to machines for applying liquids or fluids to the surfaces of materials, and particularly to the provision of an improved type of apparatus which is adapted to paint, stain, varnish, fireproof,

creosote, weatherproof and otherwise treat materials or generally subject to the action of liquids, flooring molding, cross arms and other lengths of wood or strips of moving chine; to provide means whereby the excess -material may be removed from the machine to the supply tank and reused in. order toavoid wastage, together with additional objects which will be hereinafter disclosed.

To attain the foregoing objects as well as i to gain certain further benefits and advantages, I have provided a construction illustrated in preferred form in the-accompanying drawings, wherein- Figure 1 is aside elevation, partly in section, of a machine embodying my improvements; Fig. 2 is a plan view of the machine illustrated in Fig. 1; Fig. 3 is a section takenon the line III -III of Fig. 2; Fig. 4: is a view partly in section taken on the line IV-IV of Fig.2; and Figs. 5 and 6 are enlarged views of certain details of construction of the adjustable mountings of the revolving brush and rolls respectively.

Referring now more particularly to Figs. 1 and 2 it will be seen that in carrying out my inventii'm'I provide a casing pr box like structure 7, which may be mounted adjacent the end of a planer or machine forforming flooring, molding and like articles, upon suitable supports 8 and 9, all of the parts of the wood treating mechanism being carrled in or upon the casing 7 which is preferably provided with a cover extending throughout its entire length to prevent the entrance of dust, chips and other foreign matter therein and to prevent any splashing or throwing of liquid therefrom. At the delivery end of the machine I provide a belt conveyer 11 longitudinally disposed with relation thereto for receiving the treated articles delivered therefrom, and at the end of the said receiving conveyer, a conveyer 12 disposed transverselythereto for, carrying away such articles.

expense ensuant upon rehandling' of the material to be treated may be saved, and further to effect a direct feed of such material through the machine and thereby avoid lateral displacement thereof, such material may be fed by the live rolls of the planer or To the end that the delay and additional forming machine,.but it is evident that if it be expedient to use a machine embodying my improvements in other locations, the material to betreated may be fed through my machine-by means of the live roll 13 (to which isopposed an idler roll 14), actuated by a belt 15 driving a pulley 16 at the receiving' end of the vmachine, a stationary guide block 17 and a spring guide member 18' cooperating therewith, being located adjacent the rolls 13 and 14 for the purpose of properly alining the fed material.

As the material passes the rolls 13 and 14' it is successivelyengaged by the idler rolls 20 and 21, adapted to hold it in contact with the brush devices now to be described.

- On viewing Figs. 1, 2 and 5, it will be observ'edthat I provide in the casing, 7, a liquidcontainer 19 wherein I mount rotata- -bly a brush 22, adapted to take up liquid from the container andto. act upon the lower surface of the material passing through the. machine, and provide the said brush with a. shield 23 open at the top, to prevent throwing of the liquid taken up by such brush.

For supplying the container 19 with liquid, a pump 24: is provided for lifting the liquid from the supply tank 25 by the pipe 26 leading therefrom to the container, the said container being provided with a variable overflow device comprising a pipe 27 with a bushingl9 whereby the level of the 4O vice here described, is formed with its bot-' liquid relatively to the brush maybe maintained as the brush wears, or varied as circumstances may require, and with a drain 'pipe 28 leading into said over-flow pipe, the

drain pipe being normally closed ,by a pet cook 29. It will be apparent however that various other devices for feeding the liquid might be used, depending upon the character of the fluid and of the material treated.

For driving the brush 22 and the pump 24 in unison"'wit h. the roll 13, I provide the shaft 30,-upon which the live roll 13 is mounted, with a sprocket 31, the shaft 32, upon which the rotating brush 2 2 is mounted, with a sprocket 33, and the pump 24 with a sprocket 35, a chain 34 engaging all three of said sprockets and driving the three devices simultaneously.

It is" to be observed a thorough rubbing of the liquid into the sur-' face of the material, and an lncorporation of such liquid: with such material, the brush 22;

should be revolved at a speed difierent from that of the material, and the amount of this difference may be regulated as desired by the use of sprockets of varying sizes.

For a further rubbing in of the supplied liquid I provide a series of brushes, .40, 41, 42, 43, 44, adapted to act upon the treated surface as it comes from the applying brush 22. Thesebrushes are preferably made removable, and this brush device is made sectional as here shown, toth'e end'that they may be renewed when worn, and only such part as may be Worn renewed, and the plate uponwhich said brushes are mounte is vertically adjustable'by means'of the screws'51 and 52 to accommodate difi'er'ent contours of material and compensate forwea-r of the brushes. That part of the casing below the brush detom 47 sloping toward the container 19, to the end that any liquid removed from the materialmay drain back to the tank 25 and be reused. V c 1 j At the delivery end of the machine, I

' -mount a third brush device 46 for the purpose-of removing any small amount of liquid that may remaln on the treated material after the previous treatment, in order that the conveyer 11 may not become soiled thereby.

On reference to Figs. 1, 4 and 5 it will he noted that the revolving brush 22, through which the liquid is supplied to the moving material, vis vertically adjustable by means 1 of the screws 53, 55, 55, 56 engaging'the blocks 57 and 58 in which the shaft 32 car-' rying said brush is journaled, and on viewing Figs. -1, 3 and 6 it will be observed that the rolls 14, 20 and 21 are likewise vertically adjustable in the guides 63, 63, 62 to accommodatematerial of different thicknesses and contours, by means of screws 59, 59' and 59 engagingfblocks 60, 60', 60 inwhich the thatin order to insure shafts 62, 62 and are journaled.

From Figs. 1 and 2 it will be seen that the axis of, the pulley 64, which supports one end of the'ic'onveyer belt 11 is disposed at an an gle with respect to the pulley 65 which sup- 62, carrying said rolls,

one edge of. the said belt 11 is provided with a series of outstanding pins or blocks 66, the purpose of this construction being that as the treated material comes from the machine it maybe held on the conveyer belt 11- -mercial lengths of flooringand other'material treated, and that the belt 12 may be of such lengthas is required to convey the treated material to the drying or storage rooms. v o

It is believed that in view of the foregoing description, the'mode of operation of a machine embodying my improvements will be clear to those wh'o are skilled in the art without further explanation.

Having thus described my invention and illustrated its use what I claim as new and desire to secure by Letters Patent is the following 4 1. Ina machine for treating material, in combination, means adapted to receive moving material, a container, a rotary brush in said container for applyingliquid from said container directly to the moving material and movable in the same direction as material mo'ved by said moving means, a shield for said brush located in said container and means for moving said brush at a rate of speed slower than said material. 2. In a machine for treating moving material, in combination, means adapted for receiving moving material, a container for liquid, liquid supplying means therefor, a rotary brush in said container, having that part of its periphery which contacts with the moving material moving in the same direction as said material, feeding rolls;

.port's'the opposite end of said belt, and that means having a continuous surface but being in independent sections.

i. In a machine for treating material, in combination, a casing upon which all of the parts of the material treating mechanism are carried, feeding rolls, pressure rolls, a rotary liquid applying device, rubbing means, a liquid supplying pump, driving shaft, means connecting said driving shaft, pump, and rotary applying means forv driving them all simultaneously and means for giving to said rotary liquid applying means a fed, but giving that part of its periphery which is in contact with the moving mate- 15 rial the same direction of movement as that of said material.

In testimony whereof I have hereunto signed my name in the presence of the two subscribed witnesses.
