MACHINE FOB FORMlNG ORNAMENTAL DESIGNS UPON WOOD.

SPECIFICATION forming part of Letters Patent No. 232,823, dated October 5, 1880.

Application filed March 8, 1880. (Model) To all whom it may concern:

Be it known that I, JOHN P. JAMISON, of Cambridge, in the county of Middlescx and State of Massachusetts, have invented certain new and useful Improvements in Machines for Forming Orl'iamental Designs upon Wood and other Material, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to a machine for forming ornamental designs in intaglio on wood, ivory, metal, or other non-flexible material; and it consists, first, in the combination of a typecylinder mounted in adjustable boxes, which may be raised or lowered to adapt the position of said cylinder to the thickness of the stock to be operated upon, and an impressioncylinder mounted in bearings in movable boxes resting upon pivoted levers, and a treadlc so connected to said pivoted levers that the impression-cylinder may be dropped away from the type or die cylinder to permit the insertion of the object to be ornamented, and then be raised to press the work against the type or die with the desired pressure and sufficient flexibility of action to permit the impression cylinder to accommodate itself to slight variations in the thicknesses of the two edges of the piece of stock being operated upon.

It further consists in a peculiar construction of the type or die cylinder or drum, and the ornamenting-die to be secured thereon, whereby said die may readily be secured to or removed from said cylinder, as will be more fully described.

It further consists in the combination, with the die andimpression cylinders, of an adj ustable gage located in front of said cylinders, and adapted to support one end of the stock to be operated upon and locate it in the desired position in the direction of its movement when being acted upon by the die.

It further consists in the combination, with the die and impression cylinders, of an adjustable gage adapted to locate the stock in the direction of the length of said cylinders and guide it in its passage between them, and an adjustable gage located in front of the cylinders and adapted to locate the position of the stock in the direction of its movement when being acted upon by the die and permit a free movement of said stock away from said gage when it is seized by the die.

It further consists in the combination, with an adjustable type or die cylinder, of a driving'pulley and a crank, one or both, and gearin g for imparting to said cylinder a rotary motion, all mounted upon an arm secured to or forming a part of one of the boxes, in which said'cylinder has its bearing, and adapted to be raised and lowered with said cylinder.

It further consists in the combination, with die and impression cylinders located between the frames of the machine, of a secondary die roll or disk mounted upon the die-cylinder shaft outside of the frame, and adapted to be adjusted endwise thereon and a secondary im* pression roll or disk mounted upon. an adjustable arbor outside of the frame, and adapted to support the material while being acted upon by said secondary die-roll, said secondary rolls being designed for ornamenting long strips and spaces between raised ribs that could not be readily done by the main die-cylinder.

It further consists in the combination, with the secondary die and impression rolls or disks, of a device for limiting the upward movement of the opposite end of the shaft which sup ports the secondary impression-roll, and upon which the main impression-cylinder revolves, as will be more fully described.

It further consists of a die-roll made in the form of the i'rustum of a cone, in combination with an impression-roll having a similar form and an adjustable center, all arranged and adapted for applying circular bands of ornamentation to table-tops or other circular work.

Figure l of the accompanying drawings is a plan of a machine embodying myinvention. Fig. 2 is a front elevation; Fig. 3, an elevation of the right-hand end Fig. 4, an elevation of the left-hand end. Fig. 5 is a partial front elevation, showing the machine adapted to ornamentin g circular work. Fig. 6 is a 1011- gitudinal section of the die-cylinder. Fig. 7 is a vertical transverse section on line 00 w of Fig. 6. Fig. 8 is a plan of the die-cylinder with die removed. Fig. 9 is a transverse section of the die-cylinder shaft, and showing the die-gage in elevation. Figs. 10 and 11 are, too respectively, an elevation and end view of a stop-block, to be hereinafter described.

A A are the side frames of the machine, connected together by the tie-rods or girts B B and B, and having formed therein the slots 0 and O, to receive the boxes D and D, respectively, so arranged and fitted therein that they may be moved up and down therein, as will be hereinafter described. The boxes D D are suspended from the upper part of the frames A A by means of the thumb-screws E E, which work in female screw-threads cut in the crossbars of said frames above the slots 0 G, and have their lower ends fitted to sockets in the upper sides of the boxes D D, and connected thereto by means of pins, which engage with circumferential grooves formed in said screws, so that said screws may be freely revolved therein and cause said boxes to rise or fall according to the direction in which said screws are revolved, all in a well-known manner.

F is a shaft mounted in bearings in the boxes D D, and having secured thereon, between said boxes, the die cylinder or drum G, and upon one end, outside of the frame, the spurgear wheel H, and having formed upon its other end, which. extends some distance outside of the frame, the male screw-thread a, as a means of securing thereon supplementary die-rolls, to be hereinafter described.

One of the boxes D has secured thereon the arm D which projects horizontally toward the rear, and carries at its end the stud 1), upon which are mounted the pinion I, pulley I, and crank 1 all connected together, so as to revolve together upon said stud, the teeth of the pinion I meshing into and imparting motion to the spur-gear wheel H, said pinion and pulley rising and falling with the die-cylinder as the same is adjusted to adapt it to different thicknesses of stock.

J J are two levers pivoted to the inner sides of the frames A A in frontof the slots G O, and extending horizontally toward the rear of the machine, where their rear ends are connected by the links J J to the rear ends of the treadle-levers J J which are mounted upon and move about the tie-rod B, and have their front ends connected by the pedal-board J as shown.

Each of levers J is provided with a projecting lug, 0, upon its outer side, the upper edge of which is made in the form of an inverted V, to form a sort of knife-edge, upon 1 which the box D rests in such a manner that a movement of the treadle-levers J 2 will cause the boxes D D to rise or fall.

The boxes D D are connected together by the shaft or bar K, secured therein in such a manner that it cannot be revolved, and has mounted thereon between the frames A A the the impression cylinder or drum L, which revolves freely upon said shaft whenever it is brought to bear upon'a piece of stock, so as to force it in contact with the die, and the diecylinder is revolved.

The die-cylinder Gr, secured upon its shaft by the screw 61 has formed in the center of its length a dovetailed circumferential groove, d, to which is fitted a correspondingly-shaped lug, e, which is attached to and projects inward from the inner face of the die-plate M, which may have formed upon its outer face any desired ornamental design in relief, the groove (1 being enlarged, as shown at d in Fig. 8, to permit the insertion of the lug 0 into the groove d, which serves to hold one end of the die-plate, while the other end is secured in position by a single screw, 0, which screws into a threaded hole in the cylinder G, as shown in Fig. 7.

By this construction of the die-cylinder and the die to be secured thereon dies of varying lengths may be readily and easily applied to the cylinder and secured in position thereon by the single screw 0, the lug c accommodating itself to any desired position inthe groove d.

The shaft F has secured thereon,just inside of the right-hand box D, the collar or disk N, in such a manner that it may be adjusted around said shaft and secured in any desired position thereon, the means shown for the purpose of securing said disk being the clam pscrew f.

A gage line or crease, g, is made upon the periphery of the collar N, which, incombination with the gage h, secured to the box D in front of said collar, serves as a means of determinin g the proper position of the die when the material to be ornamented is brought in contact therewith by raising the impressioncylinder preparatory to feeding said material between the die and impression-cylinder to transfer the design upon the die to the wood or other material, and thus insures the proper location of the design upon the material.

-0 is a horizontal arm projecting outward from the front edge of the left-hand frame A, and may be of any desired length, according to the work to be done upon the machine. Upon this arm 0 is adj ustably secured the gage 0, provided upon its inner edge with the inwardly-projecting lip t, the upper surface of which is at a lower level than the main part of the gage, the inner edge of which forms a shoulder, 43, against which one end of the piece of material to be ornamented (if long and the ornamentis tobe placed near one end) is placed so as to rest upon the lip t, while the other end rests upon the impression-cylinder L, with one edge against the gage P, which may be adjusted laterally to any desired position upon the threaded rod P by means of the nuts j and j, and is adapted to move about said rod as the cylinder L rises or falls.

The object of mounting the gage 0 upon the side arm, 0, and making it adjustable thereon instead of upon a table, is that the operator may have free access to the work, whether it is long or short, which is quite a desirable feature, as with the arrangement shown and described he can stand immediately in front of the machine, with the gage 0 between him rzo and the cylinders, he standing at a. greater or less distance from said cylinders, according as i the stock to be ornamented is longer or shorter.

In the rear of the die-cylinder G is thesizing or inking roll Q, and above it the distrib uting-roll Q, both mounted inmovable or ad- 'ustable boxes on the rods Q 2 or in anv. J

other well-known manner, so that sizing or ink placed upon the roll Q may be transferred to the surface of the die or type plate when it is desired to ink or gild the design.

R is a secondary (lie-roll adj ustabl y secured upon the threaded portion of the shaft F by means of the nuts 70 and 7c, and designed more especially for applying a continuous line of ornamentation to long strips of wood or other material which are passed between it and the secondary impression -roll S, mounted upon and adapted to revolve about the adjustable non-rotatin g arbor S, carried by the upwardlyprojecting arm S adjustably secured upon the projecting portion of the non-rotatin g shaft K, as shown in Figs. 2 and 4:.

When the strip of material to be ornamented by the secondary die-roll R is of even thickness, the rolls R and S will be arranged relative to each other, as shown in full line in Fig. 2 but when it is desirable to ornament a strip the two opposite sides of which are not substan tially parallel to each other, the roll R is so adjusted on shaft F as to work in conjunction with a circumferential beveled groove, 1, formed on roll S, adapted to support the strip in such a position that the surface to be acted upon by the die will lie horizontally or substantlally parallel with the surface of the die, which will be adjusted to a position directly over said groove, as shown in dotted lines in Fig. 2.

The stand or arm S is secured in the desired position on the shaft or bar K by the set-screw m, and the arbor S is secured in position in said arm by the set-screw m, while the im pression-roll S revolves thereon between the collars n and n, which are held in the desired position on the arbor by the set-screws 12 When the secondary die and impression rolls are in use for ornamenting long strips, as above described, the pressure upon the impression-roll S has a tendency to cause the right-hand end of the shaft K to rise too high, and thus throw said impression-roll out of its true position relative to the die-roll R, to counteract which I place upon the top of the righthand box D a stop-block, T, (shown in detail in Figs. 10 and 11 and in dotted line in Fig. 2,) said block being made of such a thickness for each job as will permit the right-handend of said shaft to rise no higher than the lefthand end, said block coming in contact with the upper end of the slot 0 at the same time that the impression-roll S has forced the strip of wood or other material with sufficient force against the die-roll R. The die upon the roll B being continuous, or extending entirely around saidroll, and intended to place upon the strip of wood or other material a oontinit ous line of ornamentation, no gage is required to locate the material endwise, as it can be entered at any point in the revolution of said dieroll, the plate 0 serving as a side gage to determine the distance of the ornament from the edge of the strip when said strip is of an even thickness; but when one edge is thicker than the other the side of the groove l serves the purpose of a guide, the rolls It and S being adjusted so as to bring the groove l beneath the roll R, as indicated in dotted lines in Fig. 2.

When it is desired to place upon a table top or other circular piece of wood or other material a circular line of ornamentation, the die-roll R and impression-roll S are exchanged for the conical die and impression rolls U and V, respectively, as shown in Fig. 5.

The circularpiece of material to be ornamented is placed between the conical. rolls U and V, with its center resting upon the conical adjustable center-point p and its periphery resting against the gage-plate 0, as indicated in dotted lines in Fig. 5, when the rotation of the conical die-roll U will cause the piece of material to rotate about the center 19 in an obvious manner.

A secondary ink distributing roll, W, is mounted upon the shaft of the roll Q, and a secondary inking-roll, WV, is mounted upon a stud, 0, set in the adjustable arm or plate 0 which rolls W'and Wserve to ink or size the surface of the dieroll R, all as shown in Figs. 2 and 4.

When the conical die and impression rolls are used the inking and ink-distributing rolls W and W are displaced by suitable conical inking and distributing rolls, one of which viz., the inking-roll-is shown at X in Fig. 5.

By the use of my machine designs for ornamentation or the name and address of the manufacturer may be transferred to any desired portion of a panel or other piece of stock to be used in the structure of musical instruments, furniture, or other wood work, and upon ivory or metal plates of any desired thickness from the thickness of paper to two or three inches in thickness, it being understood that the dies for use upon metal should be made of steel and hardened, as described in Letters Patent N 0. 198,847, granted to me January 1, 1878.

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

l. The combination of a die-cylinder adapted to be adjusted to a higher or lower level to adapt it to stock of widely-varyin g thicknesses, an impression-cylinder adapted to be moved toward and from said die-cylinder, one or more gages to locate the stock, and a treadle mechanism connected with and adapted to move said impressioncylinder toward the die-cylinder and (letermine the pressure between them, substantially as described.

2. The die-cylinder G, provided with the dovetailed circumferential groove (1, having saaszea the enlargement or cut-away portion 01, in combination with the segmental die M, provided with the dovetailed lug 0 and the screw 0, all arranged and adapted to operate substantially as and for the purposes described.

3. In combination with the die and impression cylinders, the gage 0, arranged in front thereof and parallel therewith, and adapted to be adjusted toward or from said cylinders upon the side supporting-arm, O, to locate the stock endwise, and provided with the ledge t, to support the rear end of the stock, substantially as described.

4. In combination with the die and impression cylinders and the gage 0, the adjustable side gage, 1?, adapted to move about its supporting-rod with the rise and fall of the impression-cylinder, substantially as described.

5. In combination with the die-cylinder G, mounted in the adjustable boxes D l), the driving mechanism lorimparting motion thereto, mounted upon an arm or support secured to and adapted to move up and down with one of the boxes D, substantially as described.

6. The combination of the secondary die-roll R, provided with a die extending entirely around its periphery and adapted to be adjusted upon its shaft in the direction of its length, and the impression roll or cylinder S,

also adapted to be adjusted in the direction of its length, and to be raised and lowered by the action of the treadle, substantially as de scribed.

7. In combination with the secondary die and impression rolls located outside of the boxes which support their shafts, the block T, provided with the bent supporting-arm for limiting the upward movement of the opposite end of the shaft or bar K, which carries the secondary impression-roll, substantially as described. v

8. The combination of the frusto-conical dieroll U, the frustoconical impression-roll V, and the adjustable center 1), all arranged and adapted to operate substantially as and for the purposes described.

9. The combination of the die-roll U and impression-roll V, both made in the form of frustums of cones, the adjustable center 19, and the gage-plate 0, all arranged and adapted to operate substantially as and for the purposes described.

Executed at Boston, Massachusetts, this 17th day of February, A. D. 1880.
