To all whom, it 71mg/ Concern:

Be it known that I, FREDRI'CH BERNER, Jn, of Indianapolis, county of Marion, and State oi' Indiana, have invented certain new and useful Improvements in Embossing-Ma'- ehines; and I do hereby declare that the fol- -lowing is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like figures refer to like parts. z

My invention relates to an improvement in `that class of embossing-machines in which the embossing-die is cylindrical, is mounted Iupon a revoluble shaft supported in adjustable bearings, and is heated to a high temperature when in use. It has been found difficult in this class of machines to provide suitable bearings fortheilie-shaft, which will not be injuriously affected by the'gheating and consequent expansion to whichtiie die-shaft is necessarily.subjected.

The object of my improvement is therefore, first, io provide bearings for the dicshaft which will properly support the dieshaft and will allow the shaft to revolve freely at any temperature without'binding or Icutting its bearings, and, second, to provide means for the vertical, the longitudinal, and the rotary adjustment of the die-shaft when heated, all as hereinafter fully set forth.

In the drawings, Figure 1 is an'end eleva tion Otan embossing-machine withmy improvements thereon. Fig. 2 is an enlarged elevation of the upper end of the'machine,

showing the embossing-dies set in position upon the shaft. Fig-3 is ase'ctional view on the line Fig. 2, looking to the left. Fig. 4 is a similar view on the line y y, Fig. V2. Fig. 5 is a perspective view of the right-hand end of the shaft, showing the notches and the inner end of the chuck with its gages with such notches.

In detail, 1 is the upper part of` the framework, and 2 the lower, 3 being the platen or table.

pin that eny 4 is the feed-ron mated beneath the table, `its upper surface passing through thesamle. This feed-roll is mounted on-a shaft 5having bearings in the sides of the lower frame-work 2. On its outer end is mounted a gear-wheel 6, engaging with a pinion 7, mounted on the shaft S, also having bearings in the lower frame, 'and near the opposite end of this shaft is a pinion l), engaging a pinion 10, mounted on a shaft 1], which carries on its outer und the fly-Wheel 1:2, thc latter heilig driven hy the friction-roll 13, mounted on the shaft 14,

on the outer end of which is -mounted a driv'- ing-pulley 15. pulley drives the friction-roll and through it the fly-wheel, and the power thus acquired is Power being applied t0 this` transmitted through the pinions to the feedy roll.

In the upper part of the frame-Work l and adapted to slide therein is a central cross-head 1G. At each end of the cross-head, on its under side, I mount a pair of friction-Wheels 17 'wheels 17 revolve easily without binding or cutting when heated to a high temperature.

21 21 are screw-rods working easily in threaded projections on the upper side of this cross-head, these screw-rods supported in the upper frame-work 1 and having on their upper ends the beveled gears 22, which engage with similar gears 23 on the cross-rod 24, which has bearings'on the top of the framework 1'. y

At one end of the rod 2l is a hand-wheel 25 rfor turning the same, which either raises or lowers the cross-head and regulates the pressure of the embossing-dies. y

Removablyattached to the boxings 2O are y metal straps 2G, which support a hollow metal die- shaft 2,8, upon which the embossing-dies 27 Y are mounted. Strapsb are so arranged as to allow the die-shaft, when not in action, to.

fall away from the friction-wheels-l' a short distance, as clearly shown in Figs. 3 and 4, so that the :heat from the shaft is not directly communicated to the wheels.

29 is a collar formed integral with this shaft,

and 30 is a removable collar working on a ICO K screw-threaded portion of the shaft, between which and the stationary collar 2!) the embossing-dies 27 are mounted, together with the spacing-rings 31, which being of diiferent` width the dies can be set at any desired position and locked by the collar 30. l

33 is a downwardly-projecting bracket attached to one side ofthe cross-head 1G, through the lower end of which passes the spindle 31, carrying a clutch or locking head 35 on its inner end, which is adapted to loosely enter and engage with notches 37 in the end ofthe shaft 2S. This spindle is used for turning the shaft when hot to any desired position for starting, and, having a stationary bearing in the bracket 33, which, when locked to the dieshaf't 28, will prevent any lateral movement of the same, also dispenses with the use of bearing-rings on such shaft, which, as before stated, is only sustained loosely by the straps 2G;` butl when a board or anyother article that is to beembossed is passed between it and the feed-roll -t the embossing-shaft is forced upward in contact with the friction-wheels 17,

against which it bears and is revolved until the Work is finished.

36 isa pipe which supplies gas orbil to feed a flame within thevdie-shaft 28 and heat the same. 4 l

By removing the dies 27and rings 31, and

putting on a brass roll ,when heated, it may -be used for aburnisher, either before or after embossing.

It is obvious that the device herein shown and described for lnounting and suspending the embossing-shaft, preventing its lateral movement, the arrangement of thefrictionwheels with anti-friction bearings ina movable cross-head and bringing them in contact with the embossing-shaft when the latter, is forced upward by contact with the wood, and means for adjusting the pressure of the die upon the material, are as well adapted to a solid as a hollow shaft, and I do not intend to limit myself to their use upon either kind of" shaft.

That claim as my invention, and desire to secure by Letters Patent, is the following:

1. In a wood-embossing machine, the combination of the main frame, the feed-roll, mounted therein, the vertically-adj ust-able cross-head arranged above'said feed-roll and having at each end a pair of friction-wheels mounted therein, the die-shaft, and the pair of straps secured to the cross-head and arranged to suspend the die-shaft below and between the friction -wheels, wherebyy the f riction-wheels form bearings for the dieshaft when it is in action, and the straps form a support for said shaftV when at rest, substantially as set forth..

2. In a wood-embossing machine, a hollow shaft, circular dies removably mounted thereon, a burner inside such shaft connected to a pipe leading to a fuel-supply, one end of such shaft carried by a clutch connected toa spind le having bearings ina bracket or support on a movable cross-head in the frame, and straps for suspending such shaft near the opposite end and intermediatebetween itI and the bearing of the spindle, such straps detaehably connected to the cross-head, all combined substantially as shown and described.

3. In a wood-embossing machine, a hollow embossing-shaft support-ed at one end by a spindle having,r bearings in a cross-head movable vertically in the frame-work, such embossing-shaft further supported by straps detaehably connected to such cross-head, friction-wheels forming bearings for` the embossing-shaft journaled in such cross-head, and

means, such as `screw-rods, connected to thecross-head and through-pinions to a horizon-` tal counter-shaft having a hand-wheel for adjusting the pressure of the embossing-dies f upon the wood, in combination with a heatingburner located inside the shaft, anda feedroll carried in the frame below the embossing-shaft, substantially as shown and described.

4. In a wood-embossing machine, a framework, an adjustable cross-head movable vertically' therein, au'embossing-shaft suspended from such cross-head, and friction-wheels journaled in such cross-head on anti-friction bearings above such embossing -shaft and adapted to contact therewith and form bearings for such shaft. when the latter is forced upward by contact of. the dies with the wood to be embossed, in combination with a feeding-roll carried below the embossing-shaft iny the frame-work, substantially as shown and described. l

5. In a'wood-embossing machine, a framework, a feed-roll having bearings therein', mechanism for driving the feed-roll, a crosshead movable vertically in the uprights of ,the
