METHOD OF AND MACHINE FOR ORNAMENTING RODS OF WOOD.

SPECIFICATION forming part of Letters Patent No. 254,535, dated March '7, 1882.

Application filed April 16, 1881.

To all whom it may concern Be it known that I, ORESTES CLEVELAND, a citizen of the United States, residing in J ersey City, county of Hudson, and State of New Jersey, have invented certain new and useful Improvements in Machines for Ornamenting Rods of Wood, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

7 In said drawings, Figure 1 represents a plan view of a machine embodying one form of the improvements, of which Fig. 2 represents an end elevation and Fig. 3 a longitudinal sectional elevation.

r 5 The object of this invention is to produce ornamental or other designs upon rods of wood by compressing or indenting portions of their surface; and the invention consists in the method, and also in certain features of the ap- 2o paratus, by which such designs are produced, all of which will be hereinafter fully explained, and pointed out in the claims.

In order to aclear understandin gof the same, a simple form of embodiment of the invention .2 5 will first be described, and then modifications of the same will be explained.

The apparatus illustrated consists of a supporting bed-plate, B, upon which is mounted a die-bed, D, furnished at an appropriate point with a die, 2, the form of which in this instance is a number of letters. This die-bed is here shown as capable of sliding in ways in the bedplate B, and is so arranged that the pattern or die (when carried by it) may be properly ad- 3 5 justedbeneath the pressure-roller R, which is mounted above it, and so as to turn in journalbearings, each consisting of a pillow-block, S,

and cap 0. This roller is supposed to be situated a proper distance above the bed-plate D to suit the dimensions of the rods to be operated upon, and is clothed with rubber or other similar elastic material capable of rendering its surface yielding, so that when the semi-rigid wooden rod is passing between its surface and 4 5 the die or pattern such an elastic pressure may be exerted upon the rod that while the pattern of the die is clearly and smoothlyimpressed or compressed into the surface of the wooden rod no breakage or marring of its surface is effected.

(No model.)

The rods, which may be either circular or polygonal in cross-section, may be fed in any manner to the machine, as between guides 34 that overhang the bed, and such others as may be necessary to direct them properly into the machine. As they come into contact with the periphery of the roller R they are rolled by it underneath its surface and between it and the bed D, and will of course be carried into contact with the die 2, passing over which they will receive the impress of its form upon such portions of their surface as the dimensions of such die are adapted in size to cover.

The elasticity of the roller must of course be so regulated that it will afford a pressure sufficient to cause the die to so impress the fibers of the wood as to bring out the form of the pattern in all of its completeness of detail, and yet avoid such a pressure as will break the fibers ofthe rod and thus mar the beauty of the work.

If the pattern to be impressed is in the form ofa single line extending longitudinally of the rod, then a die of the form shown will be used, and the die-bed may be stationary, the rod being rolled over the die by the feeding action of the roller; but if the entire surface of the rod is to be covered, or the design is to extend over any considerable part of the circumference of the rod, then the pattern will of course be made of the proper dimensions, and the bed will be caused to slide by means commonly employed to effect that result. It is to be understood, of course, that in this case the bed will slide, while the rod is being operated upon, in a direction contrary to that in which the roll is rotating, and will be so timed in its move- 85 ments as to keep the rod beneath the roll until it has comeinto contact with the whole surface of the die.

It is not necessary that the die should be carried by the bed. It will readily be seen that the operation will be practically the same if the die is placed upon the roller and the bed provided with an elastic or yielding surface.

The bed may be rotary when continuous patterns are to be produced, and even when lines 9 5 extending partially or throughout the longitudinal extent of the rod constitute the ornament; but in the latter case duplication of the pattern or complex feeding mechanism, or both, may be required.

The elastic relation between the roller and the bed, Without regard to which carries the 5 dieorpattermmaybe accomplished ashasbeen described, or by mounting the rollerin boxes having elastically-seated cup-plates or pillowblocks. The die-supporting bed may be elastically seated, or the die itself may restupon 10 an elastic cushion or cushions, any or all of which modifications are to be understood as within the scope of this invention.

What is claimed is 1. The herein-described method of impress- 15 ing designs upon rods of wood, the same consisting in rolling said rods, while subjected to a yielding presssure, across the face of a die bearingthe desired design, substantially as described.

2. The combination, with the roller and die 20 or pattern, one of which is elastically seated, of the bed D and overhanging guides 3 4, substantially as described.

In testimony whereof Ihave hereunto set my hand in the presence of two subscribing wit- 2 5 nesses.
