Nrrnn PATENT WOOD ORNAMENTATION.

SPECIFICATION forming part of Letters Patent No. 299,984, dated June 10, 1884.

To all whom it may concern.-

-' Be it known that I, JOHN P. JAMISON, of

- wood, and the other die being constructed and arranged to operate to depress the portions so outlined and complete the design.

It further consists in a novel arrangement of indexes for setting said die-rolls in the proper position ,to impress the design upon the materialat the desired point, which will .be readily understoodby reference to the description of the drawings and to the claims to be hereinafter given.

. Figure 1 of the drawings is a side elevation of a machine embodying my invention. Fig. 2 is a vertical transverse section on line as m on Fig. 1. Fig. 3 is a vertical longitudinal sec tion on line 7 3 on Fig. 2. Fig. 4 is a partial.

section on line 2 2 on Fig. 2. Fig. 5 is a section through the die-shafts, and showing the indexes in elevation.- Fig. 6 is a section through the same shafts, and showing the gears connecting said shafts in elevation. Fig.

7 is a transverse section through the outlining die.

Fig. Sis a similar section through the embossing or finishing die; and Figs. Qa'nd 10 are respectively developments of the peripheries of the outlining and finishing dies upon a flat plane.

A A are the side frames of the machine, c011- A nected together by the tie-rods B B and girts B and 13 B, and having mounted in suitable bearings formed therein the drivingshaft 0, having secured upon one end thereof the pulleys D D, andupon the other end the pinion D,

which meshes into and imparts motion to the spur-gear wheel E, mounted upon a stud set in the frame A, and having firmly secured upon its hub the pinion E, which in turn en- Application filed April 16. 1884. (No model.)

sections, is mounted upon and secured to the girts B 13 and two of the tie-rods B B, as

shown in Fig. 3. Upon this stationary table I is placed the movabletable J, provided upon its under-side with the toothed rack J, ex-

tending longitudinally thereof, the teeth of which engage with the teeth of the pinion H,

so as to be moved endwise by the rotation of said pinion, said movable table being guided in its movement by a groove, a, inthe stationary table I, into which the teeth of the rack J project, as shown in Figs. 2 and 4, said table also being provided with the adjustable abutment J 2 to compel the stock to move with the table J. Another bed-roll, H provided with a central circumferential groove, b, for the passage of the teeth of the rack J, is secured upon the shaft K, which is also mounted in bearings in the frames A A, in which it is revolved by friction of the table J thereon.

Directly above the bed-rolls H and 'H are adj ustably mounted upon the threaded shafts L and L the outliningdie M and the finishingdie M, made in the form of cylinders and clamped in the desired positions on their respective shafts by means of the nuts 0 c in a well-known manner. The shafts L and L are. mounted upon centers 01 d, set in the blocks N N, which are fitted to slide vertically in the slots N in the frames A A, said blocks being, arranged to be adjusted vertically for the purpose of adapting the die-rolls M and M to opcrate upon stock of different thicknesses by means of the screws 0 O, which work in nuts formed in the horizontal bars A of the frames A, and move endwise through the hubs of the gear-wheels I? P, which are connected thereto by splinekeys (not shown) and the longitudinal grooves c, asshown in Fig. 1, so that the screws 0 0 must revolve with said gears P P, while at the same time they are free to move upward or downward through said gears. The gear wheels P P are revolved by the intermediate gear-wheehQ, securedv to the lower end of the shaft It, having its bearing in the girt B, and having mounted upon its upper end the hand-wheel S, by revolving which both blocks N N and both dies M and M are simultaneously raised or lowered, as may be desired, to adjust the dies to the thickness of the stock to be acted upon. The outliningdie roll M has formed thereon and projecting therefrom a knife or knives, h, arranged in the form of and adapted to cut into the surface of the wood tobe ornamented the outline of the design, as shown in the transverse section of said die illustrated in Fig. 7, and in the development of the periphery of said die in Fig. 9. The finishing-die roll has for'med upon its periphery projecting surfaces corresponding to the surfaces that are to be depressed in the wood, as shown in Figs. 8 and 10, in the latter of which the parts marked 4. and j are the raised portions of the die-surface, and the serpentine surfaces k is are the sunken surfaces.

Sometimes it is desirable to have a given part of the design bear a certain relation to a given point upon the piece of wood to be ornamented; and in order that this result may be readily attained, I fit upon each of the screw-shafts L and L an index-collar, T, so that it maybe readily moved from the position it occupies in the drawings to a position in close proximity to the clamping-nut c, which secures the die M or Min position, said collar being prevented from being moved around said screw-shaft by the set-screw Z, the point of which fits accurately and works in the longitudinal groove m, formed in said screwshaft, as shown in Fig. 2. Two index-fingers, n and 0, are secured to the collar T upon opposite sides thereof, and project therefrom in oppositedirections, as shown in Fig. 2, the purpose of which will presently appear.

The block N, which carries the centers upon which are mounted those ends of the die-roll shafts L and L upon which the collars T are mounted, has cut in its inner face two perpen- 'dicular lines, 1), coincident with the axes of said shafts, which lines serve, in conjunction with the index-fingers n and o, as a means of setting the dies on their shafts, so that they shall bearthe proper relation to the work to be ornamented. The die-roll shafts are connected together so as to revolve in unison by means of the gear-wheels a" and 1", mounted, respectively, upon the shafts L and L, and the intermediate gear-wheel, s, mounted upon a stud set in the block N, as shown in Figs. 2 and 6.

The operation of my invention is as follows: The die-rolls being properly set on their shafts so that the designs upon them shall register one with the other, and the dies being ad justed in height according to the thickness of the stock to he acted upon, said stock is placed upon the table J in the desired position, with its rear end against the abutmentJ and the driving-shaft is set in motion, and the table J, with the stock thereon,will be moved endwise to carry the stock beneath the die M, which is made to rotate as soon as the stock is brought in contact therewith, and embed its knives therein and cut the outline of the design into the surface of the wood. A continuation of the forward movement brings the stock beneath the die M, which, registering accurately with the design outlined on the wood by the die M, depresses certain portions of the wood bounded by said outline, while certain other portions are left untouched, thus forming upon the surface of the wood an ornamental design in imitation of carving, having clean and well-defined outlines unmarred by having portions of the fibers .broken down beyond the outline of the design, as has often been the ease with the devices heretofore in use for this purpose. When it is desired to have a particular point in the design correspond to a given spot on the piece of wood to be ornamented, the collar T is moved along its shaft till the indexfinger 0 reaches the center of the die-face and the die is turned around its shaft-till the desired point coincides with the index-finger, when the die is firmly elamped to its shaft by screwing up the nuts 00. The collar T is then moved back to the position shown in the drawings and secured to the shaft by the setscrew Z, when said shaft is turned upon its centers till the index-finger n coincides with the line 19, when the desired point on the die will be directly in the center of the under side of the die, and the piece of stock,with the point that it is desired to have correspond with the specified point of the die marked thereon, can be placed in the desired position beneath the die, which may then be lowered upon it by turn ing the hand-wheel S. 'It is obvious that the die lW-must be so set upon its shaft that when a given point in the design upon the die M is perpendicularly below the axis of its shaft the corresponding point in the design upon die M must beat such a point that it must move around its axis of revolution a distance equal to the horizontal distance between the axes of the dies M and M before said point on die h will be perpendicularly below the axis of its shaft.

What I claim as new, and desire to'secure by Letters Patent of the United States, is-
