03310, TRADING AS THL RUDOLPH SATTLER EMBOSSING IPR-IN'lINGrJPREfSS- Application filed June 28,

To all whom it may concern lZe it known that 1, Farmers Senor, a citizen of the United States, and resident of l hiladelphia, county of Philadelphia, and State of Pennsylvania, have invented an lmprovement in Embossing Printing; Presses, of which the following is a specitieation.

The object of my invention is to provide a suitable means, in an embossing printing press, ,for removing: the surplus ink from the wiping web and returning it to the ink well; and further to provide means for treating the ink laden wiping web to a sol vent whereby the surplus ink is more easily removed therefrom and collected as above stated and also leaving thepaper web in condition whereby it may be used as a byproduct for stock in paper making.

h'ly object further, is to provide a protected source of solvent supply from which the solvent may be automatically fed to the solvent applying means (movable with the wiping web frame), so that only a small quantity of volatile solvent is exposed at any moment, but whereby applying means is replenished in a more or less continuous manner, to the end that the press may be operated for long periods without danger of fire which would result from too large a quantity of solvent in exposed condition in the operative portions of the machine.

lVith these and other objects, hereinafter set out, in view, my invention consists of certain constructions and combinations of parts fully described in the following spccifications and more particularly defined in the claims.

.My invention will be better understood by reference to the accompanying drawings, in which :-Figure l is a sectional elevation of an embossingprinting press embodying my improvements; Fin. 2 is a cam detail for operating the wiper; Fig. 3 is a cross sectional view of means for applying a solvent to the paper wiping web; Fig. 4 is a plan view of the same; Fig. 5 is an elevation of a po tion of the solvent feeding means: and Fig. 6 is a sectional view of the immediate means for removing the surplus ink from the web.

The general construction of embossing printing presses having automatic wiping devices is well known in the art, and while Specification of Letters Patent.

1917. Serial No. 177,474.

I do not in this application make claim to the machine broadly, nevertheless for imparting a better understanding of my improvements therein, 1 have shown in Fig. l a general view of the operative parts and their relation to each other, and'will now briefly describe the same. 2 is the main framing, 3 is the stamping plunger, and 4 is the die carriage and die secured therein. The die carriage is reciprocated horizontally, from the position shown, backward under the wiper pad 15 and to a position to receive ink by the ink applying roller 9, and thence forward again to the impression position shown. When the die is moved backward to receive ink, the wiper frame and pad 15 are *aised so that the paper wiping web 14 does not touch the die; but when the die has been inkedand moved forward, the wiper pad 15 is moved downward into wiping position for pressing the paper web l-l into contact with the die as it passes beneath for causing the surplus ink upon its surface to be wiped off upon the web to leave the die clean except for the ink in the engraved grooves, as in intaglio printing. The carriage and die 4; are re" ci 'Jrocated by the rocking lever 5 and links 6, 6, jointed together at 7, one of the links being hinged to the carriage and the other to the lever 5. The hinge 7 has guide rollers which traverse the guideway 8, so that the links fold at the termination of theoscillation of the lever 5 to give a'dwell to the carriage and die during the printing or embossing operation. The inking roller is carried by levers 10 which are rocked by suitable means operated from the main shaft In fact, all of the power emanates from this main shaft, but it will not be necessary to describe in detail the several instrumentalities employed, as these may be of any suitable construction so far as the utility of my invention is concerned. The means for raising and lowering the wiping pad is shown in Figs. 1 and 2, and comprises a rocking lever 29 having at one end a link construction 30 which carries the wiping frame and pad 15, said lever having at its other end connection with a power applying rod 32 guided at its upper end by the shaft and hinged at its lower end to the aforesaid lever. The rod 32 has a roller 33 working in a cam groove 31 of a cam secured to the said main shaft 34:, This means recip- 14; by the knife 25, it "falls upo I ing a trough frame ha rocates the Wiping frame and pad at properly timed intervals, as will be understood.

The wiping web is of paper and wound in a roll 16, supported so as to be unwound therefrom as required. A friction strap 16 weighted at 16 applies a braking action to prevent spinning under the intermittent pull. The web 1% passes from the roll 16 over guide 17 and between

rollers

18 and 18 thence over a guide rod 19 on the wiper frame, thence under the per pad 15 thence upward and over the solvent applying roller 20, thence under the drag roller 21. thence over the scrapim knife 25, and thence under the guide 26 to the winding mandrel 27. The mandrel 27 is intermittently driven to properly feed the web through the machine in such manner that it is fed when the embossing is taking place and when the wiper pad is out of action.

Referring to Fig. 6, it will be seen that the web 14 is bent over the scraping knife 25 at such an angle to insure the surplus ink upon its under side being; "fully scraped oil, but without abrasion of the paper. This is accomplished by having the lower portions of the roller 21 and the guide 26 be low the scraping edge of: the

nite 25; or more particularly, it is essential that the scraper edge be above the plane across the bottom portions of the

guide parts

21 and 26. it is also important that the roller 21 shall put a drag upon the web so that a substantially uniiorm friction shall be put narrow webs than wide web chute 28 and. is ten d (Fig. 1). The ink in th by the feed roller and t 11 to the inking rol r 9, r'iiicl. the die as before 0 Consid-erimg now meansQthe roller 20 is loosel C its bearings i6 in open top he? s i 44 secured to and moving; with frame. Immediately below a solvent carrying means ado solvent to the roller s pocket in which strips of wick; o6 are placed and which are kept in Contact with the bottom of the roller 20. one side of the wick pocket is solvent receiving: well 3? having small. ports 38 leadingfrom its bottom to the lower portion of ti e wick pocket (Figs. 3 and l), and outside oi"- the well 3'? is an overflow chamber 39 which may receive any accidental overflow of solvent to remove it out of possible contact with the wicks 36. This trough frame 35 is adjust able vertically 45:5 on the frame er and the quired may be had by adjusting screws ll". By this means any desired pressure between the wicks and the roller 20 may he had. The solvent may be supplied to the well 37 by a pipe 40 leading downward from the reservoir 21. The extent of feed may be adjusted by the sight-teed e2 havingthe usual adjusting nozzle; and the solvent may be completely shut off, when d sired by a valve 43 in the pipe 40. It is preferable that the valve e8 be suilieiently low in pipe .4) that th space therein between said valve and the sight-teed device will just fill the well 37 and saturate the webs, so that after the machine has been shut down, the valve 4:3 may be turned on full when starting up again without oit overflowing oi the device. While it do not restrict myself to any paricular character of solvent, gasolene. turpentine or other free solvent for the ink may he employed.

I will now describe the means for feedingthe wiping; web. its letore stated, this is accomplished by imparting rotary motion to mandrel. 27 upon which the paper wipinn; web is wound and after it has been ting means may be similar to those heretofore employed in a March 8. 1910, in which the mandrel, correoing to mandrel 27 in this application, .itermittently rotated by power transmi connections of which sprocket chain 68 part. So far as my present invention is the mandrel 2'? may be undernod as an intermittently driven paper web winding mandrel. of any suitable construction which is at for the purpose of pullino upon the web to maintain it taut and wind it into a roll with a speed cornmensurate he feeding of the web by the mandrel is filled web, the may be re- 1 toe oneration repeated. In mathis c ass t--- said power transconnectiens are of such nature that nt is imparted to the so that e web is also given an intermittent ion but as such devices are well known torn a nart of the present invenion, no details description of them will necessary The wind action of the mandrel causes given le qvh of clean web to be drawn un- 1' the wiping "cad 15, and at the same time muses the inlr carrying; web 14 to pass over the solvent applying roller 20 and the scrap extent of its vertical adjustment re- .tchine otthis character, for example as shown in Letters Patent No. 951 481 dated the winding; m .ndrel of he construcing knife 25. lhis having been done, and the carriage and die 4 having been moved under the wiping pad (but without touching the web) to a position to receive ink from the roller 9 when moved forward, the wiping pad 15 is moved downwardly by the action of cam 31 (Fig. 2), and the carriage and die l moving forward cause the die to wipe its inkd surfaceupon the under surfa .e of the web 1 below the said wiping pad 15.

By my improvements the paper web containing; the ink wiped from the die is sub jected to a solvent by the roller 20 and associated means in such a manner that the ink is l rought to an excellent condition by which it is easily removed by the scraper 25 over which the paper is drawn so that the valuable ink may be collected without removing the fiber of the paper. in this manner, a material quantity of the ink is returned for use and a minimum quantity is left upon the web, the latter being suiiiciently meager as not to objectionably irnpair the paper stock wound upon. the mandrel 27, and consequently not only is there economy in ink, but the lay-product of the waste paper is a material factor of saving.

l/Vhile l have described my improvements in the form which I have employed common cially and found well suited to the requirements of the invention, nevertheless I do not confine or restrict myself to the details, as these are susceptible of modifications and changes within the scope of mechanical skill without departing from the spirit of the invention.

Having; now described my invention, what I claim as new and desire to secure by Letters Patent, is

1. in means for applying solvent and the removal of ink from awiping web of an emaossing printing press, employing a vertically reciprocating frame having a wiping pad under which the web passes, a stationary scraper for removing the surplus ink from the wiping web, combined with a solvent applying device movable with the frame and its pad and adapted to apply a solvent to the inked web before it reaches the scraper, said solvent applying device and scraper being greatly separated to allow a sufiicient interval of time for the ink to be softened before removal by the scraper.

2. Means in the embossing printing press for removing ink from the wiping webthereof, consisting of a roller over which the inked web is drawn, a reservoir for solvent, a wick extending upward from the solvent reservoir and in contact with the roller for applying solvent thereto in a restricted but uniform manner, and a scraper arranged at the delivery side of the roller for removing the surplus ink from the web,

said scraper independently supported with reference to the roller and separated a con siderable distance from the roller to provide a sui'licient interval of time for the solvent to soften the ink before its removal.

3. An embossing printing press provided with die and pressing devices, ink applying devices, a wiping web and a pad for pressing the wiping web upon the inked die for wiping it, combined with a scraper for scraping the surplus ink from the inked web and means at the delivery side of the pad for applying a solvent to the inked web before it reaches the scraper, said means consisting of a roller over which the web passes, a vessel below the roller having a wick chamber and a solvent chamber in communicationwith each other at their lower parts, a wick in the wick chamber pressing upon the underside of the roller, and means to feed solvent to the solvent chamber, said means for applying solvent to the inked web and the scraping means being separated at a considerable distance apart to provide a suficient interval. of time for the solvent to soften the ink before its removal.

l. In means for removing ink from a wiping web of an embossing printing press, a scraper over which the inked wiping web is drawn, combined with separate guides upon opposite sides of the scraper for the web for bending the paper web over the edge ot the scraper to insure removal of the surplus ink without abrasion of the paper surfaces, t i forward guide consisting of a single roller and an adjustable friction applying means acting to apply friction directly to the roller to prevent free rotation of the roller and adjust the extent of drag upon the web.

5. Means in an embossing printingpress for removing ink from the wiping web thereof, consisting of a roller over which the inked web is drawn, a reservoir for solvent, a wick extending upward from the solvent reservoir and in contact with the roller for applying solvent thereto in a restricted but uniform manner, said wick and reservoir adjustable vertically relatively to the roller, and a scraper arranged at the delivery side of the roller for removing the surplus ink from the web, said scraper independently supported with reference to the roller and separated a considerable distance from the roller to provide a sufficient interval of time for the solvent to soften the ink before its removal.

In testimony of which invention I hereunto set my hand.
