WOOVD-GRAINING MACHINE.

SPEGIFIGATION forming part of Letters Patent N o. 675,362, dated May 28, 1901.

Application tiled Tuly 6, 1900. Serial No. 22,749. (No model.)

To @ZZ whom, 2S-may concern:

Be it known that I, BERNARD W. AUGUS- TINE, a citizen of the United States, residing at 1000 Pacific avenue, in the city and county of Alameda, in the State of California, have invented certain new and useful Improvements in Wood-Graining Machines; and I do hereby declare the following to be afull, clear, and exact description of said invention, such as will enable others skilled in the art to Which it most nearly appertains to make, use, and practice the same;

This invention relates to improvements in painting-machines, and more particularly to graining-machines.

In the draWings,'Figure lis a side elevation of a machine constructed in accordance with this invention. Fig. 2 is a plan view of the same. Fig. 3 is a vertical sectional elevation of the adj listing-Wedges on the lint-r3 3 of Fig.

1. Fig. 4 is a detail view, partly in section,

illustrating the spring-journal supporting the shaft of the design or type roller.

The object which the present invention has in View is to reproduce accurately a grain taken from the surface of one board and impressed upon another board.

My invention consists in the various matters hereinafter described and claimed;

In the description, with reference to the drawings, distinguishing letters of reference will be assigned to the various groups of mechanisms, the subsidiary parts of such` groups being distinguished by the addition 0f a numeral to the common letter.

The design or type roller A has a circumference equal to the length of an average board, say twelve feet. Secured to the face of the roller is a veneer of the Wood to be imitated. This veneer A is preferably glued to a strip of sheet metal or canvas adapted to be rigidly secured to the roller A. By this treatment of the veneer it is rendered less liable to warping, as Well as making it easy of manipulation. The roller A is mounted 'in a spring-journal having a vertical play and secured to the side beam X2 of the frame X. The reason of this play will appear later in the description. The manner of supporting the roller A is illustrated in Fig. 4. A suitable journal-boX M carries each end of the shaft a of said roller, and said boxes slide between plates M', suitably secured to the side beams X2. A pin m upon the box extends through said beam, and between the top of the beam and the head m of the pin is a spring m2, tending to force the box upwardly and thus cause the roller A to bear against the roller O. The lower periphery of the roller A is extended into the Vpaint-vat'B, resting on the floor-sill X of the frame X. The vat B contains the Wood-filler to be applied to the capillary grain on the veneer surface of the roller A. The filler is applied by means ot' the brush B', pivoted on the end of the vat B, so that its bristles sweep the surface of the roller A. To replenish the brush, it is provided with the trip arm B2, extending into the path of the pin A2 on the edge of the roller A. As the pin A2 passes the brush is submerged in the llerv and returned to its operative position by the Weight B3, adjustable on the extension B4 of the brush to regulate the pressure of the bristles on the roller A. The brush B insures an even distribution of filler over the entire surface of the roller, which is not possible by merely submerging the roller in the ller, as the air contained in the capillary interstices of the wood prevent a proper adhesion. To remove the surplus filler from the roller, the squcegee B5 is provided on the opposite side of the vatel and similarly mounted to the brush B.

The printing-roller C is of the same diameter as the roller A. Permanently attached to the roller C is a thickness of sensitive compound C', similar in composition to the printers roller or hectograph, adapted to receive' a transfer-impression of the grain on the roller A and transmit same to the surface of the board Y.

It is not advisable to take more than one impression from a single transfer 0n the roller To prepare the roller C for a new transfer, the cleaning mechanism E is provided, consisting of the vat E', filled with gasolene or some suitable solvent, through which the roller C is rotated. To remove the transfer, the brush C2 and squeegee C2 are so mounted as to bear against the surface of the roller C. The brush and the squeegee are mounted in the end of the vat E', which is pivoted at the point E4 on a bracket mounted on the floorsill X. The sliding Weight E5 permits of a ICO regulation of the pressure of the brush C2 and squeegee C3.

The idler F on the supporting-frame F, upon which the board Y rests, is adjustable vertically to regulate the pressure of the roller C against the surface of the board Y. The adjustability is effected by means of the wedge-blocks F2 on the frame F and similar blocks F3 on the strip F", which is advanced or receded by means of the screw F5 working loosely in the bracket FG on the strip F4 and being threaded in the bracket F7 on the frame of the machine. To raise the frame F, the strip F4 is drawn forward, causing the blocks F2 to ride upon the blocks F3. To prevent lateral slipping between the blocks F3 and F4, they are given the V-shaped faces shown in Fig. 3.

The feed`roller G, mounted in the frame Z, bears against the upper side of the board Y, sendingit past the roller C to receive its transfer-impression. The roller G is an idler in the frame Z to maintain the pressure between the board Y and the roller C, said pressure being effected by means of the screw-jack (l2 bearing against the beam Xof the frame X, in which it is threaded.

The feed-roll is driven by the main drivingshaft Hv by means of the belt H and pulley H2 on the feed-roll. The roller C is driven from the same source through the reversed belt H3 and pulley Hl on the shaft of roller C.

The roller A is driven by the reversed belt H5' and pulley HG on the shaft of the roller A from the pulley H4 on the shaft of the roller C. Pivoted on or near the main driving-shaft H are the beams Z', connecting iiexibly with the frame Z to maintain the centers of the feed-roll G and driving-shaft H at equal distance when the frame Z is raised or lowered to accommodate the various thicknesses of boards Y. This insures an equal tension on the belt H.

The roller A is mounted below the center of the roller C. This causes a tangential con tact between the two rollers, the pressure of the contact being regulated by the play in the mountings of the roller A, referred to earlier in this specification. The contact between these two rollers should be just sufficient to cause the surface of the roller C to pick the filler from the interstices of the veneer on the surface of the roller A.

Presuming the machine to be in operation, the process is as follows: The roller A rotates past the brush B and receives the filler, the excess of which is scraped off by the squeegee B5. As the roller A continues its rotation and comes in contact with the roller C the filler'contained in the weed-grain on the roller A is transferred to the sensitive surface on the roller C, which in turn transfers the impression to the surfaced face of the board Y, the board Y being fed through the machine by the feed-roller G, as heretofore described. At each complete revolution of the roller C the transferred impression is removed by passing through the bath-vat E, when the operation just described is repeated for each successive board. This insures a clean-cut impression being transferred to each individual board, which might not be the case were it attempted to make more than one transfer from the roller C without thoroughly cleaning the same. It is evident that any woodgrain which is capable of receiving the filler may in this manner be transferred to a board having a neutral and indistinct grain, such as pine or spruce. When it is desired to treat a board having beaded or liuted surface of not too great a depth, it has been' found possible by increasing the pressure between the roller C and the frame Z, the elasticity of the sensitive surface of the roller C being crowded into the inequalities in the surface of the board Y. After the board Y has received the transfer, as described, and is thoroughly dried it can be treated in any manner usual to wood-finishing-snch as shellacing, varnishing, and rubbing.

lVhile the mechanism of this machine has been specifically described, it will be recognized that certain mechanical substitutions may be taken advantage of without interfering with the spirit of this invention.
