V 17 Claims.

As is well known to those skilled in the art thel beating of paper'stock is accomplished by a'rotary roll which is moved downwardly as the beating progresses until the operation is complete and then must be raised again for a successive operation. This is ordinarily accomplished by an operator manually adjusting the beater roll. VAs a consequence the results of the grade of paper obtained are extremely uncertain, and moreover 1@ it is difficult inrsuccessive treatments to obtain the same results, even where the beating is supervised by the same operator.

One of the Yobjects of the present invention is to provide novel mechanical means for effecting the shifting or adjustment of the beater roll so that its adjustable movement can be denitely determined and always duplicated, the mechanism, however, permitting a variation in such adjustment for operating on diierent stock and securing different desirable results. i

A still further object is to provide means of a novel character that will in addition to feeding the roll during its operation, return it to its initial position and at a' relatively greater speed in order i that it may again be put in action without materrial loss of time.-

Still another Objectis to provide novel mechanism that will automatically stop the roll when it reaches its extreme positions both in action and on its return, and will produce a signal to call attention to the fact that it has reached the limit of its movement.

Figure 9.

'I'he carrier frame whichmaybeof any wellknown character is designated generally by the reference numeral 12, and includes swinging supports 13 pivotally mounted as indicated at 14, and

Figure 10 is a detail on theV line 10`l0` of having journal boxes in which the shaft 15 of the beater roll 16 is mounted. The supports 13 are vertically shiftable and in the disclosure shown their free endsv are hung from vertical screws 17 on which are threaded worm gears 18 having supports 19. By the rotation of the worm wheels 18 the screws are elevated or' depressed, correspondingly moving the supports 1,3 and the beater roll and its shaft. This mechanism, it is believed, is Well understood.- Extending longitudinally of the beater roll shaft 15 is an oppositely rotatable worm shaft 20 having worms 21 in mesh with the worm wheels 18 and preferably provided with a hand wheel 22 by which it can be manually turned. Obviously if the shaft 20 is rotated in one direction the worm gears lnare rotated in one direction to raise the screws 17, and if rotated in the opposite direction the screwsv will be lowered.V Automatic means are provided for effecting the rotation of the shaft 20, this means being shown in the form of an apparatus that can be mounted onthe main frame 12. A v

A supporting shelf'23 is secured, as shown at 24, to one of the standards of the frame 12, and its outer end may be sustained by a bracket 25. On this shelf is mounted a gear case 26. As shown particularly in Figures 3 and 5 the gear case contains a speed-reducing gear train. kA prime mover shaft 27 projects from the gear case and carries a pinion 28 meshing with a gear 29 on an idler shaft 3G. The gear 29 in turn carries a pinion 31 in mesh with a gear 32 on a shaft 33 that may be designated a drive shaft as hereinafter explained, this shaft 33 projecting from the rear side of the gear case, or ,in other words, from the side opposite to that from which the prime mover shaft 27 projects. As will be clear by reference to Figure 5l, it will be evident therefore that the shaft 33 is driven at a lower speed than the prime mover shaft 27. The shaft 33 carries a pinion 34 meshing with a gear 35 on an idler shaft 36 and the shaft 36 carries a pinion 37 which operates through another series of reducing gears designated generally by the reference numeral 38 to a second drive shaft 39 which projects from the fron-t side of the casing and Vob viously is rotated at a much slower speed than the shaft 33.

As shown in Figures 1 and 2 the beater roll shaft 15 has an extension 40 on which is a sprocket wheel 41, and a sprocket chain 42 passing around the sprocket wheel operates on a larger sprocket wheel 43 fixed to the shaft 27. The train of gearing including the two outlet or `with which the gears 57a drive shafts 33 and 39 are thus rotated with the beater roll by being driven from the shaft 15 thereof. The shaft 33, which projects beyond the rear side of the gear case 26, is supported by a bracket 44 and carries a sprocket wheel 45 which drives a sprocket chain 46. This sprocket wheel in turn operates on a sprocket wheel 47 forming part of a clutch member 48 that is rotatable on a countershaft 49. On said shaft is a reversely rotatable sprocket wheel 50 carried by a second clutch member 51.

The means for driving the sprocket wheel 50 and clutch member 51 is preferably as follows. The slow-moving drive shaft 39 of the speedreducing gear train and which projects from the front side of the gear case 26, has its outer end supported by a bracket 52. On the projecting end of said shaft 39 is a sprocket'wheel 53. A sprocket chain 54, driven by the sprocket wheel 53, operates on a drive sprocket 55 (see Figure 1) of a shaft 56 that projects from a casing 57 mounted on the gear case 26 and containing a change speed gearing. As shown in Figure `4 the shaft 56 carries a pair of shiftable gears 57a of different diameters keyed thereto and having a grooved hub 58 engaged by a yoke 59 on a reciprocatory shifting handle 60 (see Figure l). Parallel to the shaft 56 within the casing 57 is a driven shaft 61 carrying a pair of gears 62 are adapted to respectively mesh, accordingly as they are shifted and in a manner well understood. Obviously if the smaller of the gears 57a meshes with the larger of the gears 62, the shaft will be driven at a lower rate of speed than if the larger of the gears 57a is in mesh with the smaller of the gears 62. The shaft 61 projects from the rear side of the casing 57 and carries a sprocket wheel 63 which drives a sprocket chain 64 that in turn operates on the sprocket gear 50 of the clutch member 51.

It will thus be seen that the clutch members 48-and 51 are driven in opposite directions, the clutch member 48 at a higher speed than the clutch member 51 though the speed of the latter may be varied. `f

For the purpose of connecting either of the clutch members 48 and 51 to the countershaft 49, suitable clutch mechanism is employed, the preferred form of which is illustrated in Figure 7. A shifting clutch member 65 is keyed to the shaft 49 between the members 48 and 51 and has a Wedging device 66 which is adapted to op.- erate between spreaders 67 that in turn expand clutch rings 68 carried by the intermediate member 65 and operating against drums 69 on the inner ends of the clutch members 48 and 51. Thus when the intermediate member 65 is moved in one direction the clutch'member 48 'is connected to the shaft 49 and when shifted in the opposite `direction the clutch member 48 is released and the clutch member 51 is connected to the shaft. When the member 65 is in an intermediate position, both of the outer clutch members 48 and 51 are released and can rotate freely on the shaft. It will be clear then that the shaft 49 can be rotated in opposite directions at different rates of speed.v The countershaft 49 as shown particularly in Figure'2 has a sprocket wheel 70 fixed thereto and operating a sprocket chain 71 which drives a sprocket wheel 72 on the worm shaft 20. Obviously therefore if the countershaft is rotated in one direction or the other the shaft 20 will be correspondingly rotated and the screwsy 17 raised or lowered.

' The movement of the intermediate clutch mem- .the push button at the time the ber 65 is obtained by a shifting device comprising a reciprocatory rod 73 mounted transversely of the mechanism and having at its outer end a handle 74. Its inner end carries a yoke 75 which engages in the groove 76 of a collar 77 on the clutch member 65. By moving the shifter rearwardly therefore the clutch member 65 is caused to couple the driven clutch member 48 to the shaft 49 and by drawing forwardly upon the shifter the intermediate clutch member 65 is caused to connect the oppositely rotating clutch member 61 to the shaft 49.

In order to stop the mechanism when a desired position of the beater roll is reached, the following is preferably employed. The countershaft 49 carries a worm 78 which operates on a worm gear 79 (see Figure 7), carried by a stud shaft 80 that is located transversely to and preferably beneath the countershaft 49. On the end of the stud shaft 86 is a controlling disk 31, the detail structure ofv which is illustrated in Figure 9. It will be noted that it is provided with an annular series of threaded openings 82 which preferably are designated by a numbered scale, as shown. Adapted to be threaded into any one of these openings is a pin 83 having a projecting stud 84 which has a path that intersects an arm 85 on Vthe yoke 75 of the clutch shifter 73. y

Theremis also preferably provided an alarm device. This is .shown in the form of an electric bell 86 (see Figure l) included in a circuit S7. This circuit also includes a battery or other source of electrical energy and a push button 88. The stem or pin 83 as shown in Figures l and 10 projects through the disk sufficiently to engage stud 84 engages the arm 65 of the clutch shifting device.

It is believed that the operation of the apparatus can now be made clear. When the beating operation is started and the beater roll is in its elevated position the rotation of the beater roll and its shaft transmits motion through the sprocket gearing to the prime mover of the gear train and thus operates the drive shafts 33 and 39. These in turn rotate the clutch members 48 and 51 in opposite directions. The operator having placed the pin 83 in the desired socket, has only to push the clutch bar 73 inwardly, whereupon the slow movingv clutch member 43 is coupled to the countershaft, and through the train of gearing described the worm wheels 18 which control the screws 17 are slowly rotated in a direction to allow the beater roll supports to move downwardly. At the same time the controlling disk 81 is being rotated. The beater roll continues to lower until the stud 84 strikes the arm 85 of the gear shift bar and moves it forwardly to its neutral position, whereupon the clutch element 48 is released and the lowering mechanism comes to a standstill. At the same time the circuit 87 is closed and the alarm bell 86 rings to notify the operator that the operation is completed. He then has only to draw the clutch bar l73 forwardly, whereupon the clutch member 46 is coupled to the shaft 49, and rotating at a higher Irate of speed, the reverse rotations of the worm gears 18 are made at a corresponding rate of speed, thus lifting the beater roll more rapidly than it was allowed to lower. When the roll has reached the limit of its upward movement, the stud 84 of the control disk 8l moves the clutch shifter in the opposite direction and brings the intermediate clutch element 65 to a neutral position, so that therelevation of the roll is stopped.

Again the alarm is sounded.v

llt)

It will be seen therefore that means of a vnovel character are provided for automatically raising and lowering the beater roll at different rates of speed, and that when the limits of movement are reached, the shifting of the roll is automatically stopped. It will also be noted that the mechanism is so madeadjustable that variations both fin speed and range of movement can be obtained.

`herein described invention will be apparent to those skilled in the art without further description and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
