I APPARATUS FOR PRINTING WOOD-.GRATNING ANT) THE LIKE.

Specificatidn ,of Letters Patent.

Application filed May 13, 1909. Serial No. 495,622.

To all whom it may concern? Be it known that we, JAMES EDWIN CUR- RENT and WILLIAM JOHN lVEsLEY, both citizens of the United States, and residents of Erie, in the county of Erie and State of Pennsylvania, have invented a new and Improved Apparatus for Printing Vood- Graining and the Like, of which the following isa full, clear, and exact description.

This invention relates to certain improvements in the production of artificial wood graining, and more particularly to a device adapted to be moved over a surface and print or produce thereon the semblance of wood graining.

The mainobject of our invention is to so construct the apparatus that it may be used in producing a graining or printing on any stationarywall irrespective of its shape or position.

Our improved device is portable and operates continuously as it moves along the surface.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which sim lar characters of reference indicate correspondlng parts mall the figures, and in which- Figure l is a perspective view of an apparatus constructed in accordance with our invention; Fig. 2 is an inverted plan view of the same, parts being omitted; Fig. 3 is a transverse section on the line 33 of Fig. 2; Fig. 4 is a section similar to Fig. 8, but showing the frame in its collapsed position; and Figs. 5 and 6 are perspective views of the sections going to make up one of the extended rollers.

Our improved apparatus includes as an essential feature, a movable member having a printing surface adapted to contact with tne surface to be printed upon and remain in contacttherewith for a. short interval as the apparatus moves along. In the specific form illustrated this movable printing member is in the form of an endless belt 10, supported upon two spaced rollers 12 and 13. The belt may be made ofany suitable substantially non-elastic material, as, for instance, canvas, and its surface is provided with a coating or covering of gelatin. The

two rollers are mounted in a frame which includes side members 14 and 15 spaced apart and held rigid in respect to each other by cross braces 16 and 17. The ends of the axle of the roller 12 are secured to slides 18 movable in slots 19 in one end of the frame, while the ends of the axle of the other roller 13 are movable in slots 20 in the op osite end of the frame. For maintaining t e rollers spaced apart and thus holding the endless belt substantially taut, a coil spring 21 may be employed in each of the slots 20, for forcing the roller 13' away from the roller 12, and the slides 18.may be provided'with teeth Patented Feb. 22, 1910.

or notches for engagement with pivoted dogs or pawls 22 to limit the movement of the roller 12 toward the roller 13. Thus, the tension of the spring may be increased or decreased as desired, by the movement of the slides 18, and the endless belt may be held under the desired tension.

In preparing the belt, we first take a 1 wooden cylinder having the desired graining and accentuate this graining by deepening the same. The gelatin .is then cast on the wooden cylinder, so that whenit is removed there is formed the endless belt with the imprint of the pores of the wood in relief on the belt. The belt is then placed in position about the rollers, and as the apparatus is moved along over the surface upon which it is desired to produce the artificial graining, the rollers rotate and the belt is pressed into engagement with the surface.

In using the device the frame is preferably held at an angle to the surface over whlch it is traveling, so that the belt engages with said surface only as it passes over one roller and is spaced a considerable distance 'above. the surface as it passes over the other roller.

with its ends extending through slots 24 in the upper portion of the side members of the frame. The roller may be raised and lowered and serves not only to distribute the ink upon the endless belt, but also serves as a belt tightenen. Carried by the two side members of the frame at one side of the roller-23, is a transverse bar 25 carrying a container 26 for the ink or other coloring material. Extendingfoutwardly from this container is a brush 2? resting upon the upper surface of'the roller 23, so that as said roller rotates by its .frictional engagement with the belt, the ink is withdrawnfrom the brush and transferred to the belt. The ink is drawn from the container 26 into the shown, the side members 14 and 15 are provided with inwardly-directed arms 28 and 29, lying in parallel planes and adapted to be secured together by a set screw 30, as indicated in Fig. 4, or adapted to be spaced apart and secured rigid in respect to each other by an intermediate connecting piece 31 and two fasteners 32 and 33, as indicated in Fig. 3. Each 'of the rollers 12 and 13 may, if desired, be made up of a plurality of separate sections, any one of which may be re-.

10V8d when the side members of the frame are brought toward each other and a narrower belt is employed. As shown, each of the two'rollers is formed of two sections 3-1 and 35, which may be mounted on the same axle 36, so that the section 35 may be removed and a shorter axle be provided in place of the axle 36. Each section 34 and 35 is preferably formed of composition cast upon a hollow metaltube 37 encircling the axle. The tube acts as a bearing sleeve for the axle and prevents the composition from being worn by contact with the axle.

It is, of course, evident that the outersurface of the endless belt may be provided with any design, printing or ornamentation, which it is desired to print upon the surface of any article -or structure. The specific form illustrated is especially designed for producing a graining effect upon wood,

metal or-other suitable material, butthe use of the device is in no way limited to wood grainmg. I

Having thus described our invention, we

claim as new and desire to secure by Letters Patent:

1.'An apparatus of the class described, comprising a portable frame including side members, each having inwardly directed arms, the arms of one side member having sliding engagement with the arms of the other member and detachably secured thereto, rollers intermediate said side members and having their ends journaled in said side members adjacent the ends of the latter, an

3 endless belt encircling said rollers and presenting an outer printing surface, a combined belt tightener and -ink distributing roller carried by said side members andhaving sliding engagement therewith and resting-upon said belt, a transverse member connecting said side members in the rear of said last-mentioned roller and above said belt, and an ink container mounted on said transverse member and having a delivering and distributing brush resting upon said lastmentioned roller. 1 1

2. An apparatus of the class described, comprising a portable frame including side members, adj ustably secured together, rollers intermediate said side members and having their ends j ournaled in said side members, an endless belt encircling said rollers and presenting an outer printing surface, an ink? distributing roller carried by said side members, a transverse member'connecting said side members in the rear of said last-mentioned roller and above said belt, and an ink container mounted on said transverse member and having a delivering and distributing brush resting upon said last-mentioned roller.
