presses. In operating presses of this character it is customary to have men stationed directly by the paper roll for the purpose of regulating the tension brake on the paper roll spindle and the side adjustment of the paper roll to bring it into proper register.

These men, of course, are not in position to view the whole operation of the press.

The principal objectof this invention is to provide a simple and convenient means for bringing all these adjustments to one central point where they can be controlled by one man so located that he can view the whole operation of the press and so that the control will be easy and simple.

The invention also involves other improvements in details of construction and combinations of parts as will appear hereinafter.

Reference is to be had to the accompanying drawings, in which- Figure 1 is a side-elevation of a portion of the end of a web printing press showing one way in which this invention can be'applied thereto;

Fig. 2 is an enlarged detail side elevation partly in vertical section of mechanism pertaining to one of the web rolls;

Fig. 3 is a plan of the parts shown in Fig. 2;

Fig. 4: is an elevation partly in central vertical section of one of the operating columns;

Fig. 5 is a plan artly in section of a hand wheel for one of t e operating rods;

Fig. 6 is a sectional view on the line 6-6 of Fig. 1 on enlarged scale;

Fig. 7 is a side view of one end of one of the operating shafts; and

Fig. '8 is a similar view of the other end I thereof.

The invention is shown in these drawings as applied to a four-deck printing press, only two of the decks appearing however. This press is shown as having a frame 10 on which are mounted brackets'll of any desired kind, four for each deck of the press, except the bottom deck-which is provided with roll supports on which one of the rolls can be moved directly from the 'floor. A web spindle A is shown as provided with a bearing B which rests on the bracket 11 and with a brake drum C having a groove D at one end- On each of the brackets 11 is a lateral projection 12 provided with a vertical stationary arm 13. Pivoted to this is a lever 14 on which is a pin 15 and a socket 16. Adapted to hang from'this socket is an adnotches in the edge of the hand wheel to justing device comprising a pair of bolts 17 having right and left hand threads, and a hold it in adjusted positions. Lock nuts 21 are provided also for tightening the parts and seouringthe adjustment. On the top of the adjusting device is a pivoted latch 23' The l for engaging in the depression 16.

bottom of this turn buckle is pivoted to the end ofa lever 25. The two levers 14: and 25 are provided with brake shoes 26.

"The'inner end of the lever 25 is provided with a fork 27'. This fork embraces an operating rod 30 On this operating rod is adjustably fixed 'a collar 31 by means of which pressure can be applied to both of the brake shoes 26 by lifting the rod 30*. I

The projection 12 is formed with a cup. 32 thereon holding a spring 33 which presses against a nut 34 adjustable up and down on the collar 31. This spring presses up against the nut and by moving the nut up or down on the collar a delicate adjustment of the brake pressure can be obtained. This spring 33 also tends to counter-balance the weight of the vertical tube 30. The nut 34 can be fixed in adjusted position by a screw 35 thereon.

On the projection 12 also is located an emergency brake cylinder 40. It is provided with a piston 41 and apiston rod 42. This piston rod engages the lower brake beam 25, and is connected with it by pivot pin 43. To operatethe emergency brake air or other fluid is admitted to the cylinder 40 through an inlet 44 controlled from any convenient point on the machine. The piston is immediately given an upward motion, clamping the brake shoes firmly against the brake drum C. This can be 'used in case of emergency or when the machine is stopped. It operates independently of the operation by the rod 30, so that the adjustment of that rod need not be disturbed When the emergency brake is applied.

On the rod 30 is a spiral gear 50 meshing with a similar spiral gear 51 supported on a stud 52 fixed to the arm 13 at one end, and to the bracket 11 at the other end. This stud is provided with a screw 53 on one end and the bore of the gear 51 is screw-threaded to fit the same. Connected with the gear 51 is a disk 54 adapted to enter the groove D. It will be seen, therefore, that the rotation of the rod 30* will rotate the gear 51 on the fixed screw and move it longitudinally of the stud 52. This moves the brake drum and paper roll spindle for registration. It is obvious, therefore, that by a slight rotation of the rod 30 the register of the paper can be adjusted without disturbing the pressure of the brakes; that the tension of the web can be regulated independently by the rise and fall of the same rod 30*; and that both of these operations are entirely independent of the emergency brake cylinder which can be operated without changing the adjustments.

The parts so far described relate only to a single one of the web rolls. It will be understood that ordinarily two web rolls are mounted on the machine for each deck. In

this case the rod 30 is shown as providedwith two mechanisms for operating two web rolls simultaneously, only one of them of course, being in use at a time. For the purpose of operating the web rolls of the other decks duplicate sets of the mechanism are provided. The other sets are operated by rods 30, 30, 30. The rods 30, 30, 30 and 30, are made hollow, and they are housed one within another. The rod 30 which operates the. web rolls of the first deck terminates at a point just above the first deck, and so on. At the bottom each inner rod projects a little below the end of the one containing it.

For the purpose of operating these rods so.

that each one of them can be either turned or raised independently of each other, the following mechanism is provided. At a point convenient for an operator standing in a position to watch the whole operation of the press are two stationary operating columns 60 and 61. Extending down through one of these columns 60 are hollow operating shafts 62, 62, 62 and 62. These shafts are arranged one within the other as is the case with the rods 30, etc. Each inner one projects above the one outside it at the top'and below it at the bottom. This afi'ords a convenient way of fixing a series of hand Wheels 63, 63, 63, and 63 to the upper ends of these shafts for turning them for the purpose of adjusting the tensions of the several Web rolls. At the bottom each of these shafts is provided with a worm 64. These worms mesh with and operate a series of Worm gears 65, 65, 65, and 65, respectively. Each of these worm gears is mounted on a horizontal hollow shaft 66, on the other end of each of which is an eccentric 67. Each eccentric operates a lever 68 pivoted at 69. This lever has a roller 70 entering a groove 71 in a collar 72 fixed to the operating rod 30. Consequently the adjustment of any one of the hand wheels on the column 60 will rotate its corresponding hollow shaft 66 and the eccentric thereon, so as to operate the lever 68 and raise or lower the rod 30, 30, 30 or 30, as the case may be. This regulates the brake pressure and the tension of the web on that deck of the press.

The other column 61 is provided with a similar series of hollow shafts 73, 73, 73, 73, and hand wheels 74, 74, 74', and 74. Each of these shafts is provided with a worm meshing with one of a series of worm gears 76, 76 76", and 76 on a corresponding series of horizontal shafts 77 which pass through the shafts 66 and extend beyond them at each end. On the other end each of these shafts is provided with a spiral gear 78, these meshing respectively with a series of spiral gears 79, 79, 79", and 79, each located on one of the collars 72 which has been described. Each of these collars is keyed to one of the rods 30, etc., so that the ad ustment of one of the hand wheels 74, etc., will rotate one of the rods 30 a corresponding distance and adjust the register of the web roll. The spiral gears 50 and 51 have teeth at the same angle as the spiral gears 78 and 7 9-. Consequently any vertical movement given the tube 30 by operation of the tension adjustment will give a slight circular movement to that tube without disturbing the register adjustment. It will be obvious also that the roller 70 prevents the tension adjustment from moving when the tube 30 is given a rotary movement by the register adjustment.

Each of. the hand wheels is provided with notches 80 and with a spring-pressed pin 81 for holdin it in its adjusted positions.

It will e seen, therefore, that the man who regulates the tension of the rolls and the side register does not have to stand at the end of the press as at present, but he may stand up near the folder Where all of the webs and folded products pass under his eye. Moreover, by the use of the two tension devices for each deck, one for setting and the other for emergency, each independent of the other, it will be seen that the adjustment of the ordinary tension setting device can be maintained when the emergency device is operated. Thus, after the emergency device has been restored to normal position, the press can be started up again and the adjustment of the tension device will be the same as before. The register also will be maintained.

Although we have illustrated and described onlya single form of the invention and shown it as applied to a single type of press, we are aware of the fact that it can be applied to other types of presses and presses ,of other numbers of decks with equal facility, and that modifications can be made in the details of construction and arrangements of parts without departing from the scope of theinvention as expressed in the claims.
