filed `March 24, 1923; U. S.,Letters Patent 1,581,812 dated March 81, 1925 U. S. Letters Patent 1,513,858 datedNovember 4, 1924 and U. `SrLetters'Patent 1,481,557 dated January 22, 1924. Thaparticular machine shown consists'of the main frameportion l of suitable size, shape and material, upon wliichfiszrotatablymounted the printing' roll 2 andy im'- 7 pression roll 3, the parts being driven from a drive shaft .4. Inrthe machine illustrated', shaft .4 is driven by means of a disk 5 mounted thereon andcooperating with a friction wheel 6 `adjustably mounted on shaft .7 and driven by an electricfmotor 8 yorother source of power. The envelopes or.4 other devices to be printed upon are placed in the magazine or hopper on tabled, .are Vfed throughthe machine' and dischargedcatthc opposite side. 8

In view 4of thefacty that Ihave illustrated a machine particularly. adaptedforthe printing of envelopes, I have shownV a. flap-turning mechanism in connection with the magazine of the machine,y it being.understoodhowever, that the details of constructiono'fthis particular mechanism forms no part of thel invention herein claimed, the vsamebeing described more l in detaily inthe aforementioned pending cases and patents. .Theconstruction of themachine is such that thearticlestovbe printed upon,.regardless vof whatthey are, are f'fe'd throughpthemachine yand printed upon at high speed and the mechanisms are therefore designed Vfor high speed work. "The machine Fig. 18 is a section taken substantially on is so constructed that if there are no sheets fed through, the machine will automatically stop, and likewise the printing roll and impression roll will be separated. This need not be described in detail herein.

I have illustrated in Figs. 9 and l0 my improved type of printing roll 2, the same being adapted for printing by means of platesor to use linotype slugs or the like. Referring particularly to these figures, roll 2 is provided with a longitudinal groove 12, in Ywhich Y may be placed the slugs 13 separated by the spacers 14, the face 15 of the slugs projecting above the roll. The slugs are maintained in place by rings 16 yhaving turned over portions 17 adapted to eng-age in the slots "18.V `Any equivalent securing 'means may be employed, -but this vis simple and particularly efficient. The slugs are engaged at their edges-belowthe face 1 5 thereof. The

spring segments 16 may be slipped on er off over the ,ends of the slugs, holding the slugs and spacers` in place when they are in opera- Vtive position.A The roll may be provided with one or morevslotsf19for the securing of plates to the roll in a simil equivalentV manner.

IV have also illustrated in Figs. 9 and 10 the ring members or semi-ring members 20 which extend over the roll and may be moved into adjusted positions thereon. These ring members are formed to substantially fit the roll and are secured in place by constructing ar manner, or in any y one end as indicated at.21 and the otherend lying flat on the roll, the length of the same and spring tension holding the same in place. These are employed? both with plates and slugs. In the operation of the machine, these rings, particularly in the case of cards and envelopes, tend to steady the object to be printed upon and prevent,v movement of the same or slurring, as it may be termed, whereby the print is not sharpl and exact.

The type or 'printinggplate on the printing roll 2 is inked through suitable ink-carrying rolls arranged betweenxthe ink reservoir`24. As shown, the preferred embodimentconsists of rolls 25, 26, 27 28, 29, 30 and 31, vroll 26 being adapted to periodicallyV transfer ink from the roll to the roll 27 from which it iscarried .in regular `order on to the printing roll 2. `The rolls 27 to 31 may be rotated in any suitableV manner, roll 29 be- Ving 'usually positively driven and the others driven by a contact therewith or with each is actuated. Arm 36 is controlled by a pin 41 or the equivalent carried by a shaft 44.

As most clearly shown in Figs. v5 and 12, the pinis arranged in the hub 45 of a ratchet wheel 47, the hub 45 and a collar 46-maintaining the shaft is proper relation in the bearing formed on the frame 32. Pivotally carried by shaft 44 is an arm 48, same being secured to the shaft by a pivot pin 49 or equivalent means. Secured to the arm 48 by a pin 51 or the equivalent is a pawl 50 for actuating the ratchet 47. Arm 48 is connected with the link 54 pivotally secured to the arm by a pin 55 at one end and. at its opposite end to collar 57 by a pin 55El or the equivalent, the collar 57 being secured onvthe shaft 58, forming apart of the printingroll.

I generally prefer to provide a plurality of holes 56 so that the position of the pin 55 may be varied so as to vary the movement of the parts. Obviously, as the shaft end 58 is rotated, pin 56a being eccentric t-o the center of the shaft, causes arm 48 to be rocked back and forth 0n the pin 49, and this movement through the pawl 50 actuates the ratchet wheel 47, rotating shaft 44.V At each complete rotation of the shaft, pin 41 rocks the arm 36 and this through the pawl 39 moves the ratchet wheel 35 in a step-by-step movement, thereby similarly moving the roll 25.

The roll 26 is rotatably carried on a swinging lframe 60 pivotally supported from the part 'or brackets 32 at 61. A spring 62 or equivalent means tends tov normally pull the roll 26 into contact with the roll 25, as indicated in the full lines in Fig. 4. Arranged on shaft 44 is a cam 65 arranged to cooperate with the roll or suitable part 66. As the cam rotates with the shaft 44, it rocks the frame 46() toward the printing roll,`thereby bringing roll 26 into contact with roll 27, and nas the shaft further rotates the spring draws it back into contact with roll 25. It will thus be seen 'that the ink yfrom roll 25 is carried periodically toV roll 27 byV means of the roll 26.

` In a machine of this type where the area printed is comparatively small, it will be obvious that not as much ink is required as in the case of amachine required to ink a large type surface, and the arrangement shown 'provides ample ink for the printing roll and movably mounted` on frame 1, the carryingn mechanism being substantially a separate unit carried thereby which may be set or adjusted so as to adjust the feed in a predetermined.

manner for different jobs; and also to permit quick changes from linotype slugs to plates on the type or printing roll. As shown, the frameis provided with recesses 72 and the carrier frame with lugs 71 arranged to seat therein. The opposite end of the frameN'carries a shaft- 73 which seats in open bearings in the main frame 1 and is driven in the manner hereinafter described. Shaft 73 carries sprockets 75, over which are arranged chains 76. These chains run over sprockets 77 arranged on t-he rear shaft 73 (see Fig. 7 The chains are provided with work-engaging members 78, which engage the edge of the sheet fed on t-o the chain and carry it along to' the printing roll.

As most clearly shown in Fig. 3, the shaft 7 3 is provided with a pinion 79 meshing with the pinion 80, and this through pinion 81 and intermediate gearing or the equivalent is driven from the main drive shaft 4.k Obviously, by lifting the forward end of the frame (S9- 70, pinion 79 may be turned by hand so as to vary the adjustment of the chains relative the printing roll, after which the frame may be dropped intoV engagement with the main frame, bringing pinions 79 and 80 into driving engagement again. n Likewise, if desired, the entire carrier frame may be removed for any purpose found necessary. For example, it is generally more convenient to Work on the printing or impression roll with the conveying mechanism removed, and with this construction it is a simple matter to remove it.

As most clearly shown in Figs. 1 and 7, the frame 69-70 is providedy with a chain support 82 and carries the guides 8586, between which the envelope, card or sheet is fed from the magazine. I have shown feeding wheels 87 arranged on the shaft 73. It will charging mechanism and conveys it to a point on the guides and` 86, where it may beV picked up by the engaging members 78. The Weight ofthe material itself merely resting .65 on the feeding Wheels 87, ordinarily would' not be sufficient to cause the material to bei fed, but by employing the roll 88, this'niaintains the material in feeding engagementk with the wheels 87. kRe'stingupon the sheet or the likepassing through; the machinev it.

to somevextent, also retards the momentumv ofY the same until the sheet or card lreaches'the point where it is picked up by the engaging? members 78. Ordinarily, its weight is sulficient to cause it to function perfectly Without additional mechanism.

Referring particularly to Fig. 4', 93 is an arm'mounted on a shaft 94, the function of this arm being to turndown the iiapu of the envelope when envelopes are being passed through the machine. This arm swings about. shaft 94 as a center substantially as shown in Fig. 4 in the full lines, in which it is in its raised position. Shaft 94 is provided withv an arm 95 arranged at the outside of the frame 1. On the end 96 of the impression roll is arranged a cam- 97 arranged to coop-v erate With the lever 98 pivotally secured at 99 to the frame of the machine, the opposite end 100 being adapted to cooperate with the arm 95. 101 represents` a stop arranged onV the frame, and 102 represents a'springV (see Fig. 13) which tends tomaintain the shaft' so that the arm 93 is as shown in Fig. 4. As the shaft 96 rotates, turning the cam 97, this actuates lever 98, the end (100) of which bears on the arm 95, depressing the same so as to move the shaft 94 in a direction tot' tory for use in printingy envelopes,cards and the like. The same issuitable for printing' by means of type or printing plates, and is so constructed Vthat itl is not only easily accesysible but changes and adjustments may be made in a minimum of time. This is particularly desirable injwork of the nature set forth as owing to the high speed of operation,- the same may be easily changed for different set-ups and sizes and the time saved in high'v speed operation is not lost in adjustment Work. It is a simple matter to change fromv 1 plates to slugs or vice versa.

Having thus described my invention, it is obvious that variousy immaterial` modifications may be made in the same without depart-ing from the Vspirit `of my invention;- hence I do not Wish to' be understood as limit-V ing myself tothe exact form, construction, arrangement and combination of partsherein shownand described or uses mentioned;
