WOOD-GRAINING MACHINE.

SPECIFTCATION forming part of Letters Patent No. 288,302, dated November. 18, 1883.

Application filed May 15, 18:93. (No model.)

To (LZZ whom it may concern:

Be it known that I, EDWIN BnILLI-Nc-ER, a citizen of the United States, residing at York, in the county of York and State of Pennsylvania, have invented a new and useful Improvement in Vood-Graining Machines, of which the following is-a specification.

This improvement relates to that class of machines in which aroller engraved in relief is made to impress its design upon the material run through the machine, the designroller being suitably mounted and connected with pressurerollers for that purpose.

The object of the invention is to produce a machine in its simplest form, and so arrang ing it that the product of the machine will be double of those which have preceded it.

This improvement is more particularly adapted to cigar-box manufacturers use, a very correct imitation of expensive woods being obtained by the use of the apparatus.

The drawings herewith forming part of this specification fully disclose the nature of my improvements, like letters in which designate like parts in all of the same.

Figure 1 is a side elevation, showing the connectinggearsand feeding-tables. Fig. 2 is. a

' front elevation, showing part of countershaft,

driving-pulley, and driving-gear, the tables removed; Fig. 3, side elevation on the driv-- ing-gear side, the tables removed, in all of which A represents the side frames; A, central horizontal jaw for the reception of the design-roller-bearings boxes; A, upper vertical, and A lower vertical, jaws, for the bearing-bores of the pressure-rollers; B, caps to the jaws; 0, screws regulating the pressure upon the rolls; D, brackets for the feedingt-ables; E, feedingtables; F F, pressure-rolls; Gr, design-roll; HQHH, equal connecting gearwheels; I, main driving-wheel; J, pinion for the same; K, counter-shaft; L, driving-pol l'ey; M, pad-bearings for the countershaft; N, the driving-belt.

The construction of the machine is simple, the frames are each cast in one piece, the jaws are planed to size, and the bearing-boxes to After placing the central design-roll in position, the upper pressureroll is let down in the jaws and rests upon a thickness of rubber of about the thickness of the lumber to be passedthroughthemachine. Thelowerpressure-roll' bearings rest upon the cap until the regulating-screws are operated, when they rest upon the same; and the roll is also brought up toward the central design-roll until the space will just take the board to be grained between them. The rolls may all be of metal, or the design-roll of metal and thepressure-rolls of wood. The design-roller is first smoothly turned and polished. It is then prepared to receive a transfer of the grain of the desired wood to be imitated. The transfer may be made directly from the wood or sketched on by hand. -After the transfer has been made, the spaces betwecn'the leading lines are with proper tools out out, leaving the leading lines projecting from or in relief upon the surface of the roll.

Theoperation of the machine is as follows: Having been adjusted as described,-the lumber,previously planed to thickness, is placed convenient to the machine. Two operators are required, if the machine is to be worked to its full capacity, or if the lumber is to be grained upon both faces. 4 The lumber is first fed in from the rear table, between the design-rolland upper pressure-roll, is received by the operator at the front, dropped upon the lower table, and passes between the design-roll and lower pressure-roll. In this case the lumber is grained upon both faces, the lower face being grained in its passage from the rear'to the front, and the upper face in its passage from the front to the rear ofv the machine. For single-face graining, ungrained lumber would be placed at both front and rear of the machine, andeach operator would insert an uugrained and remove a grained piece consecutively. I prefer to perform the operation of graining before any coloring is applied to the wood, the coloring and polishing of the wood being subsequent-1y performed in special machines for that purpose. V

VVood-graining machines and rolls in themselves are not new, and are fully described in several patents, specifically in No. 238,181, February 22, 1881, E. Struppe, wood-grain ing machinery, in which the graining-roller is composed of a series of alternating diskcutters and washers secured upon a spindle by lock-nuts, and provided with a single pressure-roll, which maybe placed indiffer ently above or below the graining-roll, and which thereby limits the quantity of lumber grained to what may be entered between the tween the upper pressure and graining roll at one end ofthe machineand between the lower pressure and graining roll at the opposite end of the same, and the consequent doubling of the product of the machine. I believe, therefore, that my mode of doing the same, and the rapidity with which it may be performed by the use of my improvement, is an advance in the art.

Havingfully explained the construction and operation of my improved grainer, I desire to secure by Letters Patent the following claims thereon:

1. A wood-graining machine comprising the following elements: frames having each one central horizontal jaw and upper and lower vertical jaws, provided with suitable bearing-boxes, and caps with adjusting pressure-screws, a central graining-roll, and upper and lower pressure-rolls, suitable connecting and driving gear, with counter-shaft, pinion, and pulley thereon, substantially as shown, and for the purpose set forth. 7

2* In combination with a graining-machine frame, as described, the brackets D and tables E, the central graining-rolL'G, and pressurerolls F F, gears H I J, shaft K, and'pulley L, whereby the machine is made doubly operative, substantially as and for the purpose set forth.

3. In combination with a graining-machine frame, as described, the central graining-roll, G, constructed as described, movably fixed central to two equal-sized pressure-rolls placed vertically and adjustably, one on each side of said central roll, connected by suitable gears, H, and arranged to be driven by gears I J, and pulley L on shaft K, substantially as and for the purpose specified.
