SPECIFICATION forming part of Letters Patent N0. 461,919, dated October 27, 1891.

Application filed March 25, 1891. Serial No. 386,344. (No model.)

To aZZ whom, it mag concern..-

Be it known that I, FREDERICK 1T. HAWK- INS, a citizen of Great Britain, residing at New York city, in the county of New York and State of New York, have invented certain new and usefulImprovements in Machines for Embossing Designs on food, &c.; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it'appertains to make and use the same.

My invention has relation to improvements in machines for embossing designs on wood and other compressible material; and it has for its general object to provide a machine of a construction thoroughly capable of embossing straight, flat, turned, andirregular-shaped articles of wood or the like.

To the attainment of the foregoing and other objects the invention-consists in the construction, certain novel combinations, and adaptations of parts hereinafter described and claimed.

In the accompanying drawings, Figure l is a side elevation of my improved machine.

Fig. 2 is a front elevation of the same with a portion of the bed removed for the betterillustration of the gearing. Fig. 3 is a detail view illustrating the manner of embossing turned articles. Fig. at is a detail top plan of a portion of the gearing.

In the said drawings, similar letters indicate corresponding parts throughout the several views, referring to which- A indicates the uprights of the main frame of my improvements, which are connected by suitable horizontal beams and support the stationary open rectangular bed B, the upper side of the longitudinal branches of which are longitudinally grooved to seat and form a way for the longitudinal branches of the open rectangular adjustable bed C, which branches are longitudinally tongued on their lower sides, as illustrated, and are connected to the stationary bed by links or straps D, which are adapted to be secured at different points to the stationary bed by transverse bolts taking through the transverse apertures 41', whereby the movable bed may be adjusted so as to bring the space between the bed-rollers beneath the die-roller for embossing round articles, as will be presently described.

Mounted upon transverse shafts journaled at intervals in the side branches of the bed C, adjacent to the forward end thereof, are bedrollers F, which may have plain or engraved peripheries, as desired. Fixed upon the shafts of the said bed-rollers F, at the ends thereof, are gear-wheels a, upon which rest longitudinal rack-bars Z), which are attached to the under side of a movable reciprocating bed G, upon which fiat stock is designed to be fed to the die-roller presently to be described.

Journaled in hangers depending from a cross-bar 0, attached to the under side of the stationary bed, adjacent to the forward end thereof, is a transverse shaft H, which is pro vided adjacent to its ends with horizontal worm-wheels d, which mesh with horizontal concaved gear-wheels e, which are provided with central vertical screw-threaded apertures to receive vertically-disposed threaded rods I, which take through threaded sleeves in the cross-bar c and are provided at their upper ends with eyes to receive a transverse barf, to which are pivotally connected rearwardly extending lever-arms J, which have their rear ends pivotally connected by a depending strap 9 to weight-levers K, which are pivotally connected to the rear uprights of the frame and have their rear portions provided at intervals with apertures, whereby the weights g may be adjustably fixed thereon. Pivotally mounted upon a transverse shaft h, fixed at a suitable e1eva tion in the rear uprights of the frame, is a and is pivotally connected by the hangers 2 to the levers J, before described.

Journaled in depending bearings upon the under side of the longitudinal branches of the frame L, adjacent to the forward end thereof, is the transverse shaft j of the die-roller M, which is provided upon its periphery with suitablyengraved designs to be embossed upon the stock.

The transverse shaft H is adapted to be alternately rotated in opposite directions by the power or drivingshaft, as will be presently described, whereby it will be seen that the die-roller may be readily raised and lowered through the medium of the worms d, gears e, and rods I to permit of stock.beingplaced upon the reciprocating bed, and by the emrectangular frame L, which extends forwardly ployment of the levers J and the weighted levers K, arranged as described, it will be seen that the die or embossing roller is subjected to a yielding pressure regardless of its adjusted position.

When it is not desirable to have ayielding pressure upon the die-roller, I design employinga transverse rod or bolt 7c, which takes through the rear uprights of the frame and the levers and serves to fix the latter to the former.

Fixed by a feather upon the transverse rotatable shaft H is a sleeve Z, upon which are fixed oppositely-beveled gear-wheels m. which are designed to alternately engage a gear car- I ried by a shaft, presently to be described,

whereby the shaft H may be readily rotated in either direction.

Pivotally connected to the cross-bar c and engaging the sleeve Z is a lever 12, whereby the sleeve may be readily adjusted to bring either gear into engagement with the driving-gear.

J ournaled in suitable bearings at the rear end of the frame is the transverse drivingshaft P, upon one end of which are mounted the ordinary fast and loose pulleys forthe reception of a beltfrom the motor designed to drive the machine, and upon the shaft P, at a suitable point, is fixed a double-faced beveled gear Q, from which the feed and die rollers are driven, and the die-roller and its frame are raised and lowered through the medium of devices which I will now proceed to describe.

Journaled in suitable bearings at about the elevation illustrated is a longitudinal shaft R, upon the rear end of which is fixed a beveled gear 8, which is adapted to drive the transverse shaft l-I through the medium of the sleeve Z and gears m to raise and lower the die-roller, as has been described.

Turning loosely upon the shaft h, adjacent to one end thereof, is an idler beveled gear t, which is driven from the main drive-shaft P through the medium of a vertically-oblique shaft 10, journaled in suitable bearings and carrying a beveled gear U at its lower end to mesh with a beveled gear Q upon the shaft P, and another beveled gear 10 at its upper end to mesh with the gear 15.

Journaled in suitable bearings upon the side of the die-roller frame L is a longitudinal shaft y, upon the rear end of which is fixed a beveled gear 2, which meshes with the idler 25, while upon the forward end of said shaft is fixed another beveled gear a, which meshes with a gear I), fixed upon asleeve c,

,which turns loosely in a suitable bearing in the side of the frame L, adjacent to the' forward end thereof. Also fixed upon the sleeve 0' is a vertical gear-wheel cl, which meshes with a pinion 6 upon the end of the shaftj of the die-roller M, whereby said roller is rotated.

J ournaled in suitable bearings upon the rear side of the forward uprights is a transverse shaft A, which carries a vertical gear f at one end and has mounted upon it a sleeve B, which "carries oppositely-beveled gears g and is adaptedto be secured to the said shaft by a suitable feather, said sleeve being adapted to be moved longitudinally upon the shaft by means of alever, (not shown,) so.

alternately mesh with the respective beveled gears g. journaled in bearings upon the rear side of the forward uprights, is a large gear-wheel D, which meshes with the small gearf upon the endofshaft A',by which itis driven. Also fixed upon the shaft is is a small gear or pinion Z, which is designed to mesh with an adjustable gear-wheeLE', which is designed to normally mesh with both of the gears m upon the ends of the respective bed-roller shafts,whereby said bed-rollers are rotated in the same direction as illustrated.

The shaft of the adjustable idler E isjournaled in slotted hangers p, which are designed to be adjustably fixed to the side of the stationary bed B by a suitable transverse bolt q or the like, whereby said idler may be adjusted out. of engagement with the pinions m, whereby the adjustable bed may he slid forward and fastened in the position it will occupy when the machine is adjusted to emboss round articles. After the adjustment of the bed is effected the said idler E is adjusted so as to engage the pinion upon the rearbedroller only.

F indicates another adjustably-mounted idler-gear,'wl1ich is journaled on a shaft adapted to be vertically adjusted in the bedframe B and occupies a position on the side of the longitudinal branch of said bed-frame opposite to the idler E. This latter idlerF is adapted to mesh with the gear-wheels a on the shafts of the bed-rollers, so as to impart motion from the rear roller to the forward roller when the idler E is adjusted to engage the pinion on the rear roller only.

WVhen it is desired to emboss round articles, the reciprocating bed G is removed and a belt G is passed around the bedrollers, upon which belt the stock rests between the bedrollers and beneath the die-roller, the adjustment of the movable bed bringing the bed-' rollers into such position. By the provision of the belt it. will be seen that the stock is continuously rotated during the embossing operation.

Upon the ends of the shafts of the bed and die rollers I fix rolls H, two of which serve as bed-rolls, while the upper one serves as a dieroller, although all three might be engraved Fixed upon a transverse shaft 7c,

to emboss, if desired. The peripheries of the rolls H are concave for a portion of their length and convex for the other portion; or, in other words, they are of a compound curvilinear configuration, whereby articles of irregular shape, which cannot be embossed upon the bed-rolls by the die-roll, may be embossed by passing them through these rolls II; but, if desired, the rolls H may be of a configuration capable of embossing any specific form of stock.

In practice I design employing a table or bed in conjunction with the rolls II, which bed may be removably connected to the main frame of the machine.

Upon one end of the shaft II, I design placing a crank M whereby the said shaft may be rotated and the die supporting frame raised and lowered by hand when desired.

The general operation of the machine when employed to emboss fiat,turned, and irregular shaped articles is substantially the same, and a description of the operation when the machine is employed for fiat work is deemed sufficientfand is as follows: Motion being imparted to the main driving-shaft, it rotates the double-faced gear Q and the shafts O and R in the direction indicated by the arrows. When it is desired to start the bed-rolls, the sleeve on the shaft A is adjusted to bring one of the beveled gears g into engagement with the gear 7' upon the end of shaft C, whereby said shaft A will be rotated, and the pinion on the end thereof will rotate the gear D, and in turn the pinion Z,the idlerE, and the respective feed rollers. Motion is imparted from the dri-vingshaft to the die-roll through the pinions o and w, the shaft a, the idler t, the pinion z, the shaft y, the pinion a, the pinion b, the pinion c, the sleeve, the

gear cl thereon, and the pinion e upon the the end of the die-shaft. By adjusting the sleeve B on the shaft A so as to throw first one gear into engagement with the gear j and then the other the direction of rotation of the elements intermediate of said shaft A and the bed-rollers will be reversed,whereby it will be seen that the bed G may be reciprocated so as to repeatedly pass the stock beneath the die by the operator simply adj usting the sleeve B, which may be done by the lever h or may be accomplished by any suitable automatic device.
