HERMANN ZITZE\VITZ, OF CHICAGO, ILLINOIS.

EMBOSSING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 468,168, dated February 2, 1892.

Application led April 1S, 1891.

To al?, whom z' may concern.-

Be it known that I, HERMANN ZTTZEwirz, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Embossing-Machines, of which the following is Va specification.

The present invention relates more especially to machines for embossing wood by means of a heated pattern-roller, which is pressed with great force against the wood or other material that is to be embossed and slowly rolled over it; and the object of the said invention is to improve such machines.

To this end the invention consists in certain features of novelty that are particularly pointed out in the claims hereinafter, and which are first fully described with reference to the accompanying drawings, which are made a part of this specification, and in which- Figurel is a side elevation of the improved embossing-machine with some of the parts removed and others shown in section on lines hereinafter indicated. Fig. 2 is a sectional elevation, the section being mainly on the line 2 2, Fig. l, but partly on other lines hereinafter indicated. Fig. 3 is a horizontal section in various planes hereinafter indicated. Fig. 4 is a detail view of one of the journalboxes of the pattern-roller shaft.

The two castings forming the sides l and 2 of the base or pedestal are similar in outline and are bolted to the castings forming the back 3 and front 4, and each of said castings is bounded by a marginal flange for strengthening it. In the sides 1 and 2 are elongated openings 5, whose margins are parallel and vertical, save for a lateral recision at G.

Journaled in suitable bearings supported by the sides l and 2 is a shaft 7, having afast pulley 8, for receiving the driving-belt, and a loose pulley 9, to which said belt may be shifted to stop the machine. The belt is moved from one of these pulleys to the other by a shifter consisting of prongs l0, fixed to a rod 11, supported by the pedestal, so as to be capable of sliding endwise, and a lever 12, fulcrumed to a bracket-arm 13, projecting from the marginal flange of the side l of the Serial No. 889,400. (No model.)

double clutch, the other member 18 of which is secured to the shaft between said pinions by a spline and groove, so as to be incapable of turning upon the shaft, but capable of sliding longitudinally thereon, whereby one or the other of said pinions may be caused to turn with the shaft. The clutch is operated by means of a sliding rod 19, passing out through the side l of the pedestal and having at its outer end a handle 2O and a pair of levers 2l, connected by a pin 22, occupying a circumferential groove in the sliding member 18.

Journaled below shaft 7 is a second shaft 23, to which is secured two pinions 24 and 25 of different diameters, gearing with the pinions 15 and 16, respectively. One end of this shaft projects outside of the side l, and has secured to it a worm 26, which gears with a worm-wheel 27 secured to a vertical shaft 2S journaled in suitable bearings, supported by brackets 29 and 30 projecting from the side l. To this vertical shaft 28 near its upper end is secured a worm 3l, gearing with a worm-wheel 32 on a third horizontal shaft 33. The journal-bearings 34. of this shaft occupy the openings 5 and fit them so as to be capable of sliding vertically, but incapable of any considerable horizontal movement, andare held against longitudinal movement by lugs 34 that engage the inner faces of the sides;`

of the pedestal.

Projecting downward ironrvl the under sides of these bearings are arms@` i IOO shown in section on the line 1 1, Fig. 3. In Fig. 2 the Wheel 32, one of the boxes 34, one of the bearings 39, and the lug 41 beneath it, are shown in section in the Vertical plane of the axis of said wheel. In Fig. 3 the Worm 26 and the rear part ot' side 1 of the pedestal are shown in section in the horizontal plane of the axis of said Worm.

Secured to the shaft 33 is a roller 45. A portion of this roller and portions of the shafts 33 and 38 are omitted from Fig. 2,'in order to more clearly show the parts beyond. top of this roller occupies an opening between the front and back halves of a table 46, which is supported by anges 47 on the'V inside of" the pedestal. In Fig. 1 both halves of this table 'are 'indicated by dotted lines. 'In Fig2` the front edge of the rear half is seen in'v ele-f' vation',-(excepting so much of it'aslis hid 'by the roller 45;) and in Fig. V3 only` one-hall`` on the `front '-ha'lf'isseen. To it 'one or more adi j ustable-guides 48 may bese'cured'.-L f1 f f Securedi to' the 'tops of thefsid esl and 2 are standards 51 and 52,'-respecti`vfly,"connectedi`V attop"by a: beam' 53."-The'standard 3 3, Fig. 1.v

Before theV piece Vof material to be embossed is inserted the embossing-rolleris highly heated by means of the Bunsen burner, which maybe placed "in'any desired position With relation thereto, its heat being confinedl and made to traverse vthel periphery of' theroller by the c'urvedsliield 6 9. orderfthat'the rollerishall vbe heated uniformlyithrou'giiout its entire'circumfere'nce, it' i's'turnedcontinu driving-shaft 17,'the tfwo strands iof 'the `belt, being Acarried overt separateiidlers 84 853, journale'zidto'a` hanger 86, depending from a moving` this hand-lever in thefdireetion of'the the lever maybe brought' into engagement with onef or uanother-ofi 'series of: shoulders in'g 2'for holding it yi'n the desired position.`

It is obvious that the rollers 45 and 68 may be transposed without departing from the spirit of my invention.

The machine may be used either with or without heating the pattern-roller for embossing plastic compositions.

I am aware that it is not new to operate the platen of a press by means of toggles, and such is not the equivalent of my invention.

Having thus described' my invention, the following is what I claim as new and desire to secure by Letters Patent:

1. In an embossing-machine, the combination, with a pair of rollers and a shaft supporting each, of a rock-shaft, toggles interposed between the rock-shaft and the shaft of one of the rollers, so as to exert their force in opposite directions directly against both of` said shafts, and means for operating the rockshaft, substantially as set forth.

2.
