The accompanying drawings illustrate a preferred constructional form of the improved press. In them Figures 1 and 1* together form a side elevation showing all the organs necessary to the thirteen capacities enumerated above. Fig. 2 is a side elevation of the sheet-gripper tumbler; Fig. 3, a side elevation of a winch handle-for turning the adjusting eccentrics of a certain cylinder; Fig. 4, a'sectional detail of a gripper opener; Fig. 5, a sectional detail of a. substitute gripper opener; and Fig. 6 a sectional detail of the connection between a certain gear wheel and the shaft of the Hat bed motion. Q j

I will describe first, the organs of the improved press and their mutual relationship;

secondly, the means by which it is adapted foreach of the thirteen press capacities; and then proceed to'define by the claims, the several features of the invention.

1. The organs and their mutual relationship.

1 is one of the side frames; 2, the first motion shaft; 3, a gear fast on it and meshing withthe gear 17; 4, a gear fast on the shaft 2 and meshing with a second gear 5 axially fast to a gear 6 meshing with a gear 7 fast on shaft 8; 11, a gear fast on the shaft 10 to mesh alternately in the well known manner with the top and bottom racks 12' and 13, of the fiat bed 14; 15, the usual bedreverser engaging as heretofore in a yoke 16 at each end of the rack frame; 17, a gear normally loose on the shaft 10 between an end plate 18 and a disk 19 fast on the said shaft; and 20, 20 detachable bolts normally holding the gear 17 to the shaft 10 by being passed through both gear and disk 19.

= 23, the usual. mechanism for damping it when it is a planographic surface. When it is a typographic one, the damping mech'as nism 23"is pnt ontof action b the removal of its rollers. The inking sla (not shown for want of space) occu les the'usi'ial 'pos'ition at the right-hand looking at Fig. 1' of the bed 14.

24, is a cylinder driven by the gear 17 through a gear 25 axially fast to the former. 26 isa second cylinder and 27, athird-one. The two cylinders 26, 27 ,have ractically a common diameter which is half that of the cylinder 2.4;and a common rate of rotation consldered peripherally. 'These three cylinders are geared together, the cylinder 24 bi ng. driven by the gear ,17 or by another 0 the same size. When the said gear 17 is loose on the shaft 10, it, b reason of its meshing with'the gear com ined with the pulley 3, serves as an intermediate gear to transmit the driving effort from .the shaft 2 to the said three cylinders.

,2 8 is one of the bearings of the cylinder 24 both bearings '-having a rise and drop in the side frames 1' to provide for the said cylinder being tripped and untripped with respect .to the-printingsurface 21.

29, 29 are springs resilient between a ledge 30 on the'respective side frame 1 and the bottom face of the respective bearing. 28, and: therefore, when they'are free to do so automatically holding the cylinder 24 tripped i. e., out printing coiipeiati'on with the form21.

31 is a block fast to the bottom ends of two rods 32 fast by their top ends to the respective bearing 28.

33 is a cam groove axially fast to the gear 7 and embracin and rocking the projecting end of the pin" 4", it'hich pivotally connects ahook 35 to the outer end of an arm 36 mounted on a suitably supported shaft 37. The weight of the hook 35 tends to keep it in engagement with a second arm 38 likewise fastron the shaft .37 and having incorporated with it, an eccentric 39 capable of depressing the block 31 to-untri the cylinder 24, i. 0., to put it in print n co6peration' with the surface 21, and of isengaging from the said block to allow the springs 29 to trip the said cylinder. .The hook 335 and its cooperating organs constitutes; well known combination.

40 is a foot pedal-standing up above the feeders foot-board 41, its red 42 pivotally connected to one end of a lever 43 fulcrumed on a side frame 1 at 44 and. having a cam shaped ledge 45 at its opposite end adapted to engage, when the pedal 40 is depressed, with a roller 46 on the book 35 to disengage the latter from the arm 38' and to hold it disengaged therefrom as long as the cylmder .24 is to remain tripped.

nect-the cylinder 24 i'r'oni the eccentric 39.

'48 is"): set 'scre'w'worlting upward through each s1de frame 1 against the bottom face of the respective block 28 to hold the cylinder24 tripped, It is not considered that the combination of he above described organs28 to 48 inclusive is new.

The cylinder 24' has two operative surfaces, 49 and 50, each of which is an imptession surface or-a'n offset surface accordm'g-to the [presscapacity called for.

'51,. 51,: are the two reel rods for the blanket to make the surface 49 an ofi'set one; and: 52, 52, are the like {for the blanket to make thesuriace 5.0 an ofiset one. The paper to he printed is fed. in sheet form orig: v

53 is e feed board; 54, the sheet guide; 55, the gripper for the surface 49; 5.6-, that for the surface w; 57,.the stripper; and. 58, the delivery tapes.

- 59 is the tumbler for operating the grippeis; 60, its closing pin; 61, its opening ping. .62, ,theigripper pm lever; and 63, the cam axially fast to the shaft of the cylinder 24; for operating that lever.

-'s the'lower-blade of the lever 6,2; 65, 4) asubstitute lower blade; and 66, a substitute. opening pin, both to be substitutedfor the organs 64 and 61 respectively for the. urpose of making the closing'pin 60-.and! the opening pin 61 act together.

665, isa set screw to provide for a change in the angular position of the cam 63.

Turning. now ,to. the cylinder 26, it is held in rigid. connectionwith the cylinder 24 so as to riseand dro. with it, by its bearing boxes 67 capable o a vertical motion in the side'- fiianies 1,. by reason of their being operatively fast onbrackets 68. fast to to adjacent rods These brackets are verticallyf adjustable u on the said rods by nuts below them, toadjust the cylinder 26 in printin contact with the cylinder 24. .The cylin, er 2.6 has only one operative Surface, which is an offset one 72; and '73, 73, are the usual reel rods for the respective blanket. It coiiperates only with the cylinder 24 and is tripped and untripped with respect thereto, from the gear 7 throughan equal gear 74 with which it enoove- 75 axiallyfast to the racing a roller 76 on an arm 77 rocking on a bracket 78 on one of the side frames; a trip hook 79 engaging a stud 80 on the top end of the arm .77; a bell crank lever 81 fulcrumed on a bracket 82 fast. on the rods 32 and havmg one arm pivotall connected to thev ad acent end of the trip' ook 79 and the other to the bottom end of yahlch 18 can:

gear 74 and em nected to the arm 84 of the eccentric bearings of the said cylinder 26. There is a connection between the trip hook 79 and the pedal 40 by which the depression of the latter can trip both cylinders 24 and 26. It consists of an arm 85 fast on a shaft 14, a link 86 from it to an arm 87 fast on a stud 88 turning in the adjacent side frame and carrying a cam 89 which will, by the engagement of a roller 90 on the hook 79 with it the next time the arm 77 is rocked to the left, disengage the said hook from the last men tioned arm whenthe cylinder 26' is tripped. Means are provided for rendering the tripping and untripping mechanism just de scribed, inoperative. These consist of rocking the trip hook 7 9 upward by hand clear of both the arm 77 and the cam 89 and resting it on a fixed stud 91, and further, of an eccentric 92 turning in each bracket 68 and in operative contact with the respective box 07, both eccentrics to be turned together by a winch handle 93 in the right direction to put and hold the cylinder 26 out of contact with the cylinder 24.

Turning now to the cylinder 27, it has only one operative surface which is pianographic or typographic according to the press capacity called for. inking mechanism. The cylinder is shown as dressed with a planographic sheet 95 held to it by clamping screws 96. 97 is the usual damping mechanism to cooperate with the said surface when it is planographic. It isput out of action by removing its rollers. The cylinder 27 cooperates only with the cylinder 24 and is tripped and untripped with reference to it by a cam groove 98 axially fast to the gear 74 already described, and embracing and rocking the projecting end of the pin 99 which pivotally connects a hook 100 to the outer end of an arm 101 mounted on a shaft 102. The weight of the hook 100 tends to keep it in engagement With one arm 103 of a bell crank lever' likewise mounted on the shaft 102 and having its opposite arm 104. pivotally connected to the bottom end of a connecting rod 105 the top end of which is pivotally connected to the outer end of an arm 106 of the eccentric bearing 107 of the said cylinder 27. The tripping effect of a depression of the pedal 40 described with reference to the cylinder 21, is brought to bear upon cylinder 27, and in a substantially similar way, by an arm 108 fast on the previously mentioned stud 88 and having acam shaped ledge 109 adapted to engage, when the pedal 40 is depressed, with a roller 110 on the hook 100 to disengage the latter from the-arm 103.

111 is a set screw working downward through the hook 100 between its pivot and its operative end and bearing against a face on the arm 101 so that screwing the screw 111 down through the said hook shall, by

printing 94 is the usual rocking it away from the arm 101, disconnect the cylinder 27 from the cam groove 99 The whole of the mechanism appertaining to the cylinder 27' may be rendered inoperative. For this purpose the pivot pin 112 connecting the rod 105 to the arm 106 is removable. The cylinder itself is mounted in a frame 113 supported on the rollers 11% of a track 115 on the frame 1 and the cylinder frame 113 is held to the frame 1 by locking bolts 116 passed through lugs 117 on the latter and lugs 118 on the frame 113, which bolts are also removable.

11!), 119, are set screws working in the direction of the motion of the frame 113 along the track 115 through lugs 120 against opposite sides of the lugs 117 for the purpose of accurately adjusting the touch of the cylinder 27 upon the cylinder 24, and these lugs 120 are pivoted upon the lugs 118 so that they can be rocked up to clear the lugs 117 when the frame 113 isto be moved back along the track 115 to render the said mechanism inoperativesa-y as far as position 121or returned therefrom; 122, indicates the inoperative position of the disconnected rod 105. Although the cam groove 98 is necessarily axially fast to the gear 74 when they are working, it is adjustable about their common axis upon the said gear by bolts 123.
