To all whom z'may concern.'

, Be it known that I, WALTER H. SMITH, of Niles, in the county of Trumbull and State of Ohio, have invented certain new and use- V 5 ful Improvements in Printing-Presses; andv I do hereby declare the following to be a full, clear, and exact description of the 1n- 4vention, such aswill enable Others skllled inthe art to whichit appertains to.. make and use the same. The primary Object of this invention 1s to provide ina perfecting printing press 'havmg se arate printing couples, means for successively throwing olf the impression of the print-ing couples and automatically stopping the operation of the machine after the impression of vthe last couple has been T e resent invention is especially designed ior machines for printing, or numbering andprintin'g, in one or more colors,

A on both sides Of a sheet, and embodies two printing couples or combined printng'and number-lng couples, thestock being autoother.

It is the purpose of my invention not only to throw-off successively the impression of the separate couples, but to defer stopping the machine while stock is in transit therethrough, and to then automatically operate the stop mechanism.

It is s. further object of my invention to automatically restore the impression of the 85 second printing couple when the impression of the first couple is unt-ripped. And a further object is to enable a perfecting press to print stock on one side only and yet be capable of automatically. tripping the impression and stop mechanism in the event of any interruption in the feed supply.

The invention will be hereinafter fully set forth and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a printingr press showing my improvements. Fig. 2 is an enlarged side view of the tripping and stop mechanism. Fig. 3 is a plan view of the parts shown in Fig. 2. Fig. 4 is a fragmentary end view. Fig. 5 is a detail.

Referring to the drawings, 1 designates a form-carrying cylinder and 2 an impression cylinder of a printing couple. Coperating 65 with theimpression cylinder is a third cylmatically conveyed from one couple to the impression of the first couple in the event of inder 3 which ,may be a numbering cylinder or a second form-cylinder. The printing may be in different colors, since the cylinders l and 3 have separate ink reservoirs and rolls. The stock may be fed to the cylinders automatically or by hand. IA have shown at 4 an automatic sheet feed of the Harris type, and at 5 conveyer rolls for transferringthe stock to the cylinders.

-6 designates a form-carrying cylinder, and 7 an impression-cylinder of a secondprinting couple. Cop'erating with impression cylinder 7 is a third cylinder 8 which may be a numbering cylinder or a'second form cylinder, and these two cylinders, 6 and 8, may have separate reservoirs and ink rolls, as shown. This second couple is shown on a lower plane than the first vcou le, but this is not necessary. Stock a ter passing through the first couple is conveyed by any suitablemeans, such as tapes 9, to the second couple, and from the latter may be de- ,livered to a folding machine or perforator,

or onto an ordinary la boy, or it maybe passed to and through another printing couple.

In connection with the first couple I employ some suitable stock-controlled trip mechanism for tripping or throwing-olf the any interruption in the feed supply. Any suitable means may be employed for this purpose, that shown at 10 being constructed after the manner contemplated by Letters Patent No. 925,047, issued to me June 15, 1909. IVhen the trip mechanism is operated, by failure in the feed-supply, it will disengage a dog 11 and release a spring-impelled shaft. 12 to which the eccentric bearings' 13 of impression cylinder 2 are con- 95 nected. 'When the impression is tripped the partial turning of shait 1Q. under the action of its spring.I causes the longitudinal movement of a shifting bar 14 which is shown as occupying an inclined position.

At its lower end this bar has a lug or projection 15 on its underside, and above and to one side of this lug is a roller 1G. The lug 1 5 normally rests in a'notch 17 in a 1ongitudinally-movable controlling bar 18 and 105 moved in its guide 20, and as roller 16 rides 110 Amachine while Stock is in transit between separate couples, I provide' for holdingccinl trolling'ba/r 18 in'itsset or shift position until/the last sheet or .piece of stock has passed through the final cou le.' For this purpose bar 18 is providedl with a second notch 23 into which tlie hookedend ofl a! lever 24-is forced.` by a spring 25 when such notch isbrought beneath such end.

The controlling bar 18.will remain held by 'j lever 24 until, .according to the arrangement shown, the impression of the second couple tripped. A

' `{.lhe impression 4cylinder 7 Aof the second couple is mounted -neccntric bearings 25,

^ which bearings ai'egciinected to a springiinpelled shaftn26 which is normally' held by a. lev'e 2T which lis 'caused to release said shaftwhen'trip mechanism, indicated at 28, islactuabed i'ipon failure in the feed supply. lever 27 1s connected by a link 29 to an ifm SO'of theftrip mechanism, and when "the latter is actuated by failure in the feed rejecting end of arm 30 will pp' the ree end of lever 24 to release enga br118 lwhich then be impelled, by its spring 19 the machine. This will not occur, however, until the tri -mechanism of the seoond'cou le is actuate bythe nonpresence Aoft stc `If additional couples should be employed the im ressions will be .40 tripped successively, but t e prime mover would not be brought to rest until after the last piece of stock has assed throughA the final couple. I preferab y provide the final couple with means for automatically restoring the impression in each cycle of operation, and the Asame is shown as comprising a lever 35, a constantly-operating cam 36, and a projection 37 of shaft 26 with which a lateral projection 38 of lever" 35 wi ll engage to move said shaft to restore the impression. Unless the feed supply has been renewed, however, the shaft 26 will not be engaged and held by lever 27.

From what has been said it will be seen that notwithstanding the distance that separates the two printing couples the tripping of the first couple 'will not interfere with the continued operation of the second couple until the sheet'last through the first couple has passed through the second couple, and thereupon the controlling bar of the primemover will be released to bring the machine to rest.` p

In. order that a press normally intended as a perfecting press may be utilized -for printing on one side only,-I provide strippers 40,A

-stock instead of passing to conveyer 9 will .fall onto lay-boy 41, but when the machine is used for printing on both sides the strippers are moved into the positions shown in full lines. When the machine is used for printing on only one side it is necessary to ring it to rest when the impression of the first couple is thrown off. To this end I rovide an eccentric 42 to prevent lever 24 rom engaging controlling bar' 18. When bar 14 is actuated by the partial 'rotation of spring-impelled shaft 12, and bar 18 is moved longitudinally, in opposition to its spring, such bar will immediatelyV fly back,

under the infiuence of its spring, as soon as lug 15 is lifted from notch 17, and thereby stop the press.
