From the cam-shaft is driven by means of change-wheels another shaft, upon which are keyed a number of levers or catches, which, in revolving, come in contact with the lips or catches on the locking-bars and withdraw them,

so .as to allow the weighted levers to fall and bring the printing-roller into contact with the fabric being printed. When the printing-rollers have completed the cross-patterns the cams again raise the slides, together with the 1 weighted levers, and bring the printing-rollers away-from the fabric. They are then looked, as before, by the locking-bars beingacted upon by the levers This arrangement may be applied to any numher of printing-rollers consistent witl'rthe diameter of the main bowl. The cams or tappets on the camshaft, as well as the levers or catches on the shaft carrying them, are placed one behind another to correspond-with the dis- 2 tanee from one printing-roller to another.

And in order that our said invention may be fully understood, we shall now proceed more particularly to describe the same, and for that purpose shall refer to the several figures on 0 the annexed sheet of drawings, the same letlers of reference indicating corresponding parts in all the figures.

Figure 1 of the accompanying drawings represents an end sectional elevation of an ordi- 5 nary printing'machine having our said invention applied thereto; and Fig. 2 is a longitudinal section of the same, corresponding to Fig. 1. Fig. 3, Sheet 2, is an end elevation of the machine, showing the gearing for the cam- 0 shafts; Figs. 4, 5, 6, 7, and 8, Sheet 3, views awn/of one form of adjustable cam 5 and Figs. 9, 10,

B B B B are ordinary printing-rollers. O is the main bowl ot'the printing-machine. D D D are spur-wheels upon the shafts 1 0 of the printing-rollers, the said spur-wheels gearinginto the crown-wheel E of the machine, whereby the printing-rollers receive rotary motion.

F is a spur-wheel, which is shaft 2 of the main bowl 0, and drives the wheel G upon the shaft M. his shaft has keyed upon it the wheel H, which is arranged so as to be capable of sliding upon the shaft 7 in order to put the whole apparatus for blocking-work or intermittent printing, to which it imparts motion, out of action when it is required to do ordinary printing. The motion is transmitted from the shaft M through the intervention of the spur-wheel H or carrieron which are engraved the keyed upon the wheel I and a spur-pinion, J, to a shaft, K, which has keyed thereon a number of sets of cams 'or tappets, L L

lips or catches 3 of intervention of the number of cross-pattern-printing rollers employed, the cams or tappets being arranged in duplicate at opposite ends of the machine. These cams or tappets operate in the following manner, the action of one set of themvidelicet, that of the cams or tappets Lbeing taken as an example of the operation of the whole: The cams or tappets L, Fig. 2, in revolving act through the intervention of the rollers N upon the slides m, which they lift, together with the weighted levers X, centered at 4, and the levers Y centered at 5, carrying the cross-pattern-printing roller A and its appurtenances, and in this manner the said roller is brought away from the fabric being printed. While the sides are raised the weights acting upon the levers P draw the sliding-bars or looks 0 under the lips or catches 3 on the slides m, so as to hold the printing roller from the fabric while the cams make a certain number of revolutions, which is regulated in the following manner, in order to correspond to the distance between the cross-patterns.

R is a shaft, which is driven from the carnshaft K by means of a pinion, T, and a changewheel, U, which latter is a stud-wheel working upon the radial arm W, and driving the wheel V, Fig. 3, fast upon the shaft R. Upon this shaft are also keyed a number of levers or catches, S, which in revolving comeiu contact with such of the lips O of the sliding-bars or locks as may be within the range of their motion. For example, assuming that the set of slides m has been locked in the manner hereinbefore described, the corresponding levers or catches S in revolving come in contact with the lips O of the corresponding sliding-bars or looks O, and withdraw them clear of the the slides at, so as to allow the Weighted levers X to fall and bring the printing-roller into contact with thef'abric being printed. hen the printing-roller has completed the cross-pattern the cams L again raise the slides m, together with the weighted levers X, and bring the printing-roller away from the fabric, and the slides are looked, as before, by the locks or sliding-bars O and the levers and weightsl The action of theother cams or tappets issimilar to that of the cams or tappets L, hereinbefore described. For example, the cams or tappets L act through the slides m and thus, by operating the levers X work the printing-roller A which is locked and released in the manner hereinbefore explained. Similarly with respect to the cams or tappets L slides mfland levers X which work the printing-roller A, and also with respect to the cams or tappets L, slides on, and levers X, which work the printing-roller A 7 he cams or tappets upon the shaft K are made adjustable, so that varied lengths of cross-patterns may be printed. This adjustment may be obtained by forming the eamsin two parts, bolted together, one part sliding behind the other, so as to make the raised part of the cam longer or shorter, as the pattern requires; or the adjustment may be effected by the removal or addition of certain sections or lengths from or to the cams, or in any other convenient manner.

Figs. 4, 5, 6, 7, and 8 illustrate a form of cam in which the adjustment is obtained by the removal and insertion of sections. The base 1 of the cam which is to be keyed or otherwise secured to the shaft has recesses 2 in its periphery-four in the present instance-for the reception of corresponding projections on the sections 3 4 of the bearing portions of the cam, these sections being held in place by side plates, 5 6, bolted to the base 1. To change the size of the cam, all that is necessary is to remove the section 4, say, (Fig. 4,) and substitute a section with an enlargement of the desired sizesay like that shown in Fig. 8.

In the modification shown in Figs. 9, 10, and 11 the adjustment is obtained by making the cam in two parts, 7 8, bolted together by bolts and nuts 9, one part being adjustable on the other, when the nuts are loosened, by allowing the bolts to pass through curred slots 10 in the movable piece 8. Y

We claim as our invention-' l. The combination of the printing-bowl and printing-roller with levers supporting said roller and tending to keep it in contact with the'bowl, cams for raising the levers to withdraw the roller, and automatic lockin g devices, substantially as described, for retaining the levers in a raised position.

2. The combination of the printing-bowl and printing-roller with levers supporting said roller and tending to keep it in contact with the bowl, cams for raising the levers to withdraw the roller, automatic locking devices for the lever, and rotary cams for periodically releasing the locking devices, all substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
