Be it known that l, Josnrnt lit. Dunner, a

citizen of the United States. residing; at.

-"l"he invention consists in certain novel features of construction. and combinations of parts which will be hereinafter described and pointed out in theclainis.

in the accompanying drawings, Figure 1 top plan view of my invention, Fig. 2 is a View in side elevation, Fig. 3 is a longitudinal vertical sectional view, Fig. at is a view in side elevation of the mechanism for actuating the rolls of cloth, Fig. 5 is a sec tional view through the operating mechanism disclosed in Fig. 4:, Fig. 6 is a view in elevation of the bracket and roll for iininersing the fabric, and Fig. 7 .is a view in side elevation of the ineans' for adjusting the upper wringing roll. I

' The upright 1, bracket 2, table 3 and ink-. ing mechanism 4 are old and form apart of the embossing presses now upon the market. The wiper hcad 5 which is conncctedto a pivoted arm 6 is also old in the art and the head is provided with a flexible pad 7.preferably of sponge-rubber. The shaft 8 is mounted on the bracket 2 and supports the roll of cloth or other material 9 which is' conducted "down into the tank 1.0 which is supportedfupon the bracket 2, the tank being provided with a liquid for saturating the cloth. Brackets 11 are connected to they tank and journalcd in the brackets is, a wringing roll 12. An upper wringing; roll 13 is adjustably mounted in slots 1+1 formed in the brackets. Thumbscre'ws 15 are connected to the upper ends of the brackets and v tineciihzatiesv of Letters Eatent.

hearing against the thumhscrews and rolls are coiled springs 16. By the adjustment of the thumb-screws l5.the moisture can be wrung froin the fabric as it pass s between the wringing rolls- However. it is the ob- -ject of my invention. to regulate this adjustment so that only a certain amount of the liquid will be removed from the cloth.

An immersing bracket 1'!" is supported in thetank 10, one end of the bracket being; provided with a pin 18 which'is adapted to enter a. socket l9 the other end of the bracket being supported by a pin 20. The.

bracket 17 carries a roll 18 beneath-which the cloth 9 passes whereby the cloth is thoroughly saturated in the liquid before passing between the wringing rolls 12 and 13.

The cloth passes from the upper wringing roll 13 down and beneath the wiper-head 5,

then up and over an idler 21 and thence to a rotating or winding roll shaft 22. Loosely mounted upon the winding roll shaft 22 1s a sprocket-wheel and mounted upon the hub of the sprocket-wheel is a gear-Wheel 24-, the gear-wheel being keyed to the sprocke'bwheel by a key 25. A friction pad 26 is keyed to the shaft22 and bears againstthe s11 rocket-.wheel 23. A washer 27 keyed to the shaft 22 bears against the friction pad 26 and nuts 28, 28 regulate the frictional engagement between. the sprocket-wheel 23 and the pad 20.

jack-shaft 29 is mounted upon the frame or upright 1 and is'provided with two levels 30 and 31. Mounted upon the level 3U of the shaft is a gear-wheel 32 which is adapted to mesh with the gearovheel 24. Connected to the gear-wheel 32 is a ratchetqvheei 33. A semi-circular cam 3 1 is mounted on the level 31 of the shaft 29 and bears against the shoulder formed on the shaft, the cam 34:

being provided with a handle'ElG for shifting it to its different positions. Loosely mount,

ed upon the cam is anarin 37 which is .providedwith a pawl 38-adapted to engage the ratchet-teeth of the ratchet-wheel 33'.

ing the lever to be moved, whereby the pawl A lever 39-is connected to the arm 37 for caus-= r 33, thereby causing the ratchet-wheel to roagainst movement. The cam 34 is received stationary and the wiper-head is caused to pened cloth to come in contact with the die will be caused to revolve and the wringing roll 12 will rotate through the sprocketthe cloth, and as the winding roll 22 operates movement of the wiper-head 5 without 38 will engage the ratchet-wheel 33 causing the gear-wheel 32 tobe rotated, thereby transmitting rotary motion to the gearwheel 24 and causing the cloth to be wound upon the winding roll The lever 39 is operated in any suitable manner and is intended to intermittently operate the ratchetwheel, causing the cloth to be wound upon the winding roll.

A sprocket-wheel 40 is mounted on the lower wringing roll shaft 12. A sprocket chain 41 connects'the sprocket-wheels -l0 and 23 for causing the wringing roll 12 to be operated' upon the operation of the winding roll 22. Suppose the die or plate has been inked by the inking mechanism and it is desired to remove the surplus ink from the die or plate: The winding mechanism is be lowered to cause the moistened or damor plate for removing the surplus ink. When the wiper-head 5 is raised the lever 39 will be operated, causin g the pawl 38 to engage the ratchet-teeth of the ratchet-wheel tate and at the same time rotate the gear wheel 32. The gear-wheel 32 transmits rotary motion to the gear-wheel 24 and the sprocket-wheel 23. The winding shaft 22 wheels 23 and 40 by their connection by the sprocket-chain 41, thereby causing the cloth to be unwound from the shaft 8, drawing it through the" tank 10 and between the wringing rolls 13 and 13 where a certain amount of moisture will be removed from the cloth will be wound thereon, bringing a new surface of the moistened cloth beneath the wiper-head 5 for the next operation.

A dog l2 is connected to the frame 1 and is adapted to engage the ratchet-teeth of the ratchet-wheel 33 for holding the wheel beneath the pawl 38 and regulates the engagement of the pawl with the teeth of theratchet-wheel. By moving the cam by the handle 36 the pawl will engage the ratchet- Wheel for causing the wheel to be revolved a greater or less distance, according to the direction in which the cam is moved. When the winding roll 22 has a tendency to move fart-her than the supply of cloth or other material will warrant, the friction between the friction pad 26 and the sprocket-wheel 23 is suificient to cause the winding roll shaft to remain stationary and to allow the sprocket-wheel '23 to move sufficiently to cause the wringing roll 12 to operate to cause a sufiicient supply of cloth to be unwound from the shaft 8 to permit of the straining or stretching the cloth in the removal of the surpluslnk from the die or plate.

Hcretofore, the die or plate has been operated upon by paper or cloth for removing the surplus. ink, but there are many objections to the use of the cloth or paper, as it requires a great deal of power to create a suliicient impression to absorb or remove the ink from the plate or-die. With my improvement I moisten the fabric or cloth and cause it to pass through wringing rolls and by the adjustment of the upper wringing roll 13 sufficient pressure will be formed for removing enough of the water or liquid from the cloth to obtain the proper removal of the surplus ink fromthe die or plate. By m'oistening or having the cloth sufficiently moist the surplus ink can be removed from the die or plate without smearing; it will clearly cut the ink from the die and gives a richertone to the work. It will not squash or make a feather edge to the printing, which 15 noticeable with the dry paper or cloth. The dry paper or cloth has a tendency to remove or absorb all of the moisture from the die or plate due to the fact that a great deal of pressure is necessary to cause the removal of the ink from the die or plate by the dry paper or fabric.

Having fully described myinvention, what I claim and desire to secure by Letters-Patent, is:

-1. A power embossing press comprising a plate, inking mechanism for applying ink to the plate, a pad, a tank adapted to have a liquid therein, wringing rolls, a cloth fed through the tank and between the wringing rolls and across the surface of the pad, a winding roll for one end of the cloth, means for imparting an intermittent motion to the winding roll,- and means transmitting said intermittent motion from the winding roll to one of the wringing rolls, whereby posi tive movement is imparted to the latter in unison'with that of the winding roll.

3. A power embossing-press comprising inking mechanism for applying ink to a plate, a tank having a liquid therein, a clpth passing through the tank, upper and lower wringing rolls between which the cloth for operating the ratehet-wheel wheizebylg passes for removing the moisture therefrom, motion' is transmitted to the Winding shaft- .sprocket-Wheel of the lower wringing roll, on the wringing r011. a inding shaft having 'a gearovheel and In testimony whereof I aflix my signature, sprocket-Wheel mounted thereon, a chain in the presence of two Witnesses.
