y invention relates to a flatbed-rotary printing press and more particularly to antismutting mechanism for such press, with the object in view of providing efi'ective means for automatically shifting the impressing cylinder bodily away from the form cylinder whenever one or more of several impres- -sion segments are not in use, and Whenever a paper carrying segment on the impression cylinder fails to receive a paper to be printed. 4

Fig. 4 is an enlarged top plan view of the impression cylinder and its accessories. Fig. 5 is a View of the same in end elevation. Fig. 6 is a detail elevation partly in section.

Fig. 8 is a view in detail showing the vibrating arm whichsupports the electro-magnet for controlling the position of the impression cylinder with respect to the form cylinder and the cam for operating the arm, and Fig. 9 is a view in detail showing the arrangement -of the contact plates for maintaining the electric circuit closed when the impression cylinder is not carrying paper to be printed.
The present application is a division of my pending application Serial No. 539,942, filed January 25, 1910.
The frame of the machine is denoted by 1'. The drive shaft, denoted by 2, is provided with fast and loose pulleys 3 and 4, which receive power from a suitable source not shown. The drive shaft 2 also carries a balance wheel 5. The shaft on which the form cylinder is carried is denoted by 6. It is provided with a, spur wheel 8,
through which the shaft receives motion by means of a pinion 7 on the drive shaft 2-.
The impression cylinder is here shown as provided with two oppositely disposed impression se ents, denoted respectively byv and 10. hese segments are mounted in suitable end frames 11 carried by a shaft 12. The latter is mounted in eccentric bearin s as will hereinafter particularly appear.- T e relation of the segments 9 and 10 to the ,form cylinder is such that they will normally travel along the type beds of the form cy1- inder with their Qurved surfaces sufiiciently close to the said to press the aper carried by them into printin contac with the type held on said beds. hese segments 9 and l0] are quite similar in construction and are provided with s ltable grippers and blankets, the particu ar construction of which 1s not recited here as they form no part of the present invention. The shaft 12- 1s driven by suitable gearin from the" form cylinder shaft, the particu ar structure of is gearing forming no part of my present inventlon.
To prevent the face of an impression segment of the impression cylinder from engaging the face of the type on the form cylinder when, either from intention any impression segment is not provi ed with a sheet to be rinted, or, unintentionally a sheet fails to e fed in posit-ion, the shaft of.
the impression cylinder and hence the im-. pression c linder itself is automatically moved bodi y away froni the face of the type and held away during the time the face of the impression segment is traveling dver the face of the type. This is accompli thdd as follows: The impression cylinder shaft- 12 is mounted eccentrically in bearings one of which is shown at 13, Fig. 5, it being understood that a similar bearing is-provided for the shaft 12 at the opposite side of the frame. The bearin 1P3 and its companion are'in turn rotatab y mounted'in suitable bearin in the sup orting frame. Pitmen 14 an 15 are joinFed respectively to s lit collars l6 clamped. on the bearing)? an its companion the said pitman being acetate at their opposite ends by cams 17, 18 on the cam shaft 19, the-latterbeing driven from the drive shaft 2 throu h suitable gears connecting it with the drive shaft. A spring 20 tends to draw the rollers 21, 22, on the pitmcn into engagement with the earns 17, 18, lowering thepitmen and hence rocking the bearing 13 and its companion and thereby moving the shaft 12 suliiciently to prevent the face of an impression segment from touching the face of the type. The pitmen 14, 15, are held from unintentional dropping by stop blocks 23, adjnstably attached to the pitmen by means, for exan'iple, of an clon gated slot and set screw 24, 25, which stop blocks rest on a shoulder 26 on a slide 27 supported in a way 28 secured to the frame, the siide being provided with a pin 29 against which the end of a slide operating 'arm 30 bears.
Itis to be'understood that there are two slides similarly constructed and arranged,
one for each stop block, and that there are two slide operating arms connected by a bottom element 31, forming a general U- shaped structure pivotally secured to the outer sides of the frame 1, one of the pivots being shown at 32. The element 31 is provided with an armature33 which coiiperates with an eleetro-magnet 3d carried by the lower end of a vibrating arm 35 pivoted .to the frame at 36 and connected by a. pitman 37 with the shaft 19 on which the forked end of the pitman rides. The pitman 37 is provided with a roller 38 in position to engage a cam 39 similar to the cam 17, to
1 rock the arm 35 against the tension of its reor l 1') 5 men the img'irr tracting spring 4.0. The slides are moved by springs, one 41 being shown in Fig. 5, into position to arrest the stop block and its companion. thereby holding the pitmen 14, 15, suspended and the impression cylinder in. printing position. The parts will remain in this position so iong as the electromagnet remains dc nergized, the latter swinging back and forth as the arm 35 is swung during the revolution of the shaft 19, without effect upon the element 31 and its arms. When, however, the electromagnet 34- is energized, it will attract the armature 33 and hence cause the element 31 and its arms to swing in a direction to move the slides against the tcnsionof the spring' tl and its conirmnionythercby dislodging the .sto fblocks from the slides, allowing the pit- "r'nen 14, 15, to drop and thereby throw the impressioncylinder out of touch with the type: Once ha ing dropped, the pitmen 14, 15, will, remain do-wn until. their operating Cams 1?, 18, a nin lift them and thereby n segment into printing roaches its sheet receiving :position it position.
complete 1 e The energizing and denergizinp; of the electromagnet 34: is accomplished as follows: An electric circuit is formed by wires 42, 43 leading from the opposite poles of a battery 44- to binding posts 45, 16, on a projection of the frame 1. Curved contact strips 4.7, 48, are carried by an end frame of the impression cylinder, a pair of these strips for each impression ction of the cylihdcr', in position to contact respectively with the binding posts 25, 46, before the face of the impresiion section p 5 along over the type. These contact st ps or plates are connected with contact terminals 49, 50, exposed on the face of the impression section and at all other points suitably insulated from the cyiindcr. The construction here shown is in-- suiated Wires 51, 52, leading from the strips 1?, 48, through robber plugs 53, set'in the cylinder. A bridge piece 54 of suitable con, ducting material, as, for example, brass, is pivoted to bracket secured to and insulated from the advance edge of the impression section in position for the branches of its forked end to swing into and out of contact with the terminals 49, 50, at the face of the impression section. A spring 56 tends to hold the bridge piece out of contact with. the terminals. The bridge piece is forced into contact with the terminals to eiectric circuit. through the strips 47, 4:3 and binding posts 45, 16, by a dog 57 cons ting in the present instance of a flat piece oi steel having its end spiit to form branches 58, 59, and secured to an arm 60 attached to an insulating block 6]., fixed on a rock shaft 62 mounted in the end frames of the cyiinder and provided at one end with a crank 63, the pin on which is provided with roiicr in position to engage a. care (it fixed to the frame 1 and so shaped as to rock the dog 5'? and hold it out of position to press the bridge piece 54 into contact with the terminals 49 50, during the in when the im 'rre on segment is traveling in termediaie of snot 'ive sheet receiving positions, but permitting the dog 57 to he rocked by its actuating spring 65 attached to an arm es on its shaft just after the imprcssion segment has reached its position to receive a sheet to be printed, in a direction to press the branches of the bridge piece into contact with the terminals 49, 50, thereby completing the circuit through the strips 47, 48 and clcctromagnet 34 and causing the shaft of the impression cylinder and hence when. a sheet cf on an impression i enr' pling; when wession seci ill will not h e no slicer i W non. l
