The rock-shaft9passcsthroughthis sleeve, this invention, but only so much of aprintingand the sleeve thus becomes the pivot for the machine is shown as is required to illustrate catclrlever. This catch-lever is provided with the application of these improvements and two lateral arms, 1) E, which unite and carry 5 their construction and operation. a stud, 5, that co-operates with a cam-bar, 4,

5 In the drawings, Figures 1, 2, and S are side the hooked end of which may be engaged with elevations. Fig. 1 exhibits the impressionand disengaged from the stud 5 by means of a cylinder wheel as about to engage with the coupling-bar, 7, whose upper end is pivoted bed rack at the beginning of the forward to an offset piece, 8, on the jointed end of the travel to produce an impression, the parts he cam-bar 4.

This shaft 1 carries cams 2 and 3, one upon each side of the stock F of the cam-bar 4, which cams respectively bear upon friction-rolls 40 41, carried by said stock F. The catch-lever O carries another stud, 13, which co-operates with a hook ed locking-arm, 14, that is pivoted to the framework,and operated by means of the couplingbar 7 through a rod, 15, pivoted at one end to the arm 14 and at the other to the bar 7. This rock-shaft 9 may be moved by a hand-lever, 16, keyed to its outer end. Upon moving this lever to the left the shaft 9 is rocked and causes the cam 10 to lift the bar 7 and connectingrod 15, thus lifting the cam-bar4 from off the stud 5 and raising the arm 14 so that its hooked end grasps the stud 13. The lever 0, then engaged with the cylinder, is thus coupled to the arm 14,and the actuating cam bar 4 is uncoupled from the arm E of the lever O, as in Fig. 3, thereby locking the lever and cylinder stationary and leaving the crank-shaft 1, the cams 2 3, bar 4, and the type-bed free to continue the movements to distribute the ink, or for other purposes, as long as is desired, as in inking up.

When it is desired to have the cylinder cooperate with each forward run of the typebed, the hand-lever 16 is moved to the right, as in Fig. 1,which causes the cam to draw the hooked arm 14 out of engagement with the stud 13 and the cam-bar 4 down until its hooked end engages with the stud 5. The catch-lever O is thus unlocked from the frame and is free to move, and, being coupled to the cam-bar 4, will be vibrated through the reciprocation of the bar 4 by means of the cams 2 3, to cause the impression-cylinder to co-opcrate with the bed at each forward stroke of the latter, as in single inking.

To provide for double inking, by causing the impression-cylinder to cooperate with the bed at its alternate forward runs an automatic means for properly rocking the shaft 9, and thus coupling anduncoupling the catch-lever G at proper intervals, is provided as follows: The rock-shaft 9 is provided with a leverclutch, 22, which turns loosely on the shaft, and said lever-clutch is connected by a rod, 21, with a crank-pin, 20, carried by a wheel,

' 18, on shaft 19, which wheel gears with a pinion, 17, of half its size on the crank-shaft 1, said leverclutch thus being rocked once back and forth at each second revolution of the shaft 1. The companion clutch 23 slides on the shaftflandits feather24, and when coupled with them the clutch 22 will impart to the shaft 9and its cam 10a rocking motion,which will engage and disengage "the cam-bar 4 and arm 14 with and from the catch-lever Cthrough the coupling-bar 7 and connecting-rod 15, as hereinbefore described with reference to the hand-lever 16.

The recesses in the cam-bar 4 and arm 14 are of such a depth that during the operation of changing the one does not let go of the lever C until after the other has grasped it, thus keeping the lever always under control.

As the wheel 18 makes but one revolution to two complete runs of the type-bed, it follows that the impression-cylinder will co-opcrate with each alternate run of the bed and remain stationary during the intermediate runs, thus causing the form to be inked twice to each impression.

To connect and disconnect the

clutches

22 and 23, the latter is moved back and forth by means of a rod, 25, which carries a forked arm, 26, that enters into a groove in the clutch. This rod 25 extends outward through the framework and' has a half-circle guard, 27, on its outer end outside of the hand-lever l6, and

this guard serves to hold the hand-lever 16 in both its right-hand and'left-hand positions by means of the locking-screws 28 29, the points of which enter a hole in the lever.

When it is desired to make the cylinder cooperative with the alternate forward runs of the bed, the rod 25 is pulled outward, thus first drawing the point of the lockingscrew out of the hand-lever 16, which is thus set free, and next draws the sliding clutch 23 into worlv ing contact with the rocking clutch 22, as in Fig. 5, by which the catch-lever C will bring the cylinder in and out of operation with the alternate runs of the bed, as has been described.

It is only while thebed is making its return run that the cam-bar 4 can be connected to and disconnected from the catch-lever C, and to prevent this being done at the wrong time when changing by the hand-lever 16, a governing device for controlling the movements- This is con-- of the hand-lever is provided. structed as follows: A disk, I, is secured to the outer end of the shaft 19, and it has two sharp-pointed curved guards, 31 and 32, secured in a circle to its face with a certain interval, as 33 or 34, between each of them. These guards co-operate with a bar, 35, one end of which is jointed to the hand-lever 16, while the opposite end is forked and embraces the shaft 19, and it has alozenge-shaped stoppiece, 36, fixed on its side next to the curved guards 31 32 in such a position that when the hand-lever 16 is turned to its right-hand position the piece 36 will be outside the path of the guards, and when the lever is in its left-hand position the piece 36 will be inside the path of the guards. It is obvious from this that the lever 16 cannot be turned from one position to the other to connect and disconnect the. cam-bar4from the catch-lever 0, except at such times as when a space, 33 or 34, between the curved guards is in front of the piece 36,

and the curved guards are so placed that one of the

spaces

33 or 34 is in front of the piece 36 only when the bed is making its backward run. If by chance the hand-lever should be left in a midway position with the cam-bar 4, and the recessed arm 14 both grasping the catch-lever O, the curved guards 31 or 32 would strike the piece 36 on the bar 35 and complete either the engagement or disengagement of the catch-lever C. By this simple mechanism a movement of the hand-lever 16 to the right will cause the coupling-bar 7 to hold the cam-bar 4 coupled with the catch-lever O, and hence the cylinder and bed will cooperate at each forward run of the latter. By moving the hand-lever to the left the coupling-bar will disengage the cam-bar 4 from the catch-lever O, and hence no movement of the cylinder will occur. By sliding the rod 25 outward the shaft 9 is clutched to the lever 22, and receives a rocking motion, properly timed by means of the proportion of the wheels 17 18 to cause the coupling-bar 7 to couple and uncouple the cam-bar and catch-lever at proper times, and thus engage the cylinder-wheel and bed-rack at alternate forward runs of the bed, in the latter adjustment the guard 27 being removed so as to leavethe handlever 16 free to oscilate back and forth.

The fly-lever 90 and its lockinglever 91 and the cam 92 are illustrated herein simply to show their relation to the other mechanisms.
