This invention relates to improvements in paper making machines, and has for its object to provide, in connection with a stock box, a breast roll which projects into one corner of the box and forms a part, thereof.

It is an object of this invention to provide, in connection with a stock box, a breast roll which projects into one corner of the box and supports a wire netting onto which the stock is to be distributed, elevated and transported horizontally.

It is an object to provide, in connection with a stock box, a scraper extending from the botto'm of the box to engage a breast roll substantially on a line with the horizontal radius of the roll so that as the sto'ck is fed onto a wire screen supported and moved thereby, the stock will be elevated and transported from the box in a substantially horizontal direction.

It is also an object of the invention to provide, in connection with paper stock feeding means, a pair of adjustable slices for regulating the distribution of stock upon a wire screen.

It is also anobject to provide, in connection with a stock box, rotary drum stirrers in which the central part of each stirrer will rotate in a direction opposite the peripheral part thereof, or in the same direction at a different speed.

These and other advantages will appear from the following description taken in connection with the drawings.

Referring to the drawings:

Figure 1 is a vertical, longitudinal section through a paper making machine.

Figure 2 is a vertical section through the feed roll and the parts of the paper machine adjacent thereto, showing a modified form of drum stirrer in which the central part of each drum will move at a speed different from the speed of the peripheral part.

Figure 3 shows a transverse section of the scraper.

Figure 4 is a top plan view of one side of the machine.

Figure 5 is a section on the line 55 of Figure 1.

Figure 6 is a section on the. line 6-6 of Figure 1.

The stock from which the paper is made contained in a box having a fioo'r or bottom I, sides 2, a rear not shown, and a front wall 3, adjustably supported between the side walls, which are held in proper position with relation to the front wall by means of transverse rods- 2a. :The front wall is supported so thatit may be adjusted forwardly and rearwardly to a limited extent by means of screws 4, one at each side of the box operated by a hand wheel 5 and supported by a bracket 6 extending inwardly from the side wall.

Extending across from one side wall to the other is a shaft 1, suitably supported at its ends on some fixed part of the front wall. This shaft is provided at each end, adjacent the side wall, with a gear 8 surrounding the shaft and projecting into a pocket 9 formed in the front wall. The 10 gear 8 meshes with a vertically disposed worm l0, which has on its upper end a handle I l by which the worm is rotated for rotation on the shaft 1. On the shaft 7 there is a plurality of eccentrics l2 around which there is a loop mem- 15 her [3, which has extending therefrom a threaded shaft I4. Each eccentric projects into a pocket formed in the front wall, similar to the pocket 9 and likewise designated by the numeral 9.

There is also supported by the front wall a shaft 20 I5 for each shaft I4 and connected thereto by a threaded sleeve l6, which is rotated by a hand wheel II. By means of the hand wheels ll the shafts l4 and I5 may be adjusted with relation to each other. The lower ends of the shafts i5 5 have thereon a slice l8. This slice extends transversely of a wire netting 23 supported on a breast roll 20 at one end of the wire netting, while the other end of the wire netting is supported by a similar roll, not shown. For the purpose of hold- 3o ing the shafts IS in proper relation to the front wall there is provided for each shaft I5 a clamp member l9, in the form of a bolt with a nut thereon. The breast roll 20 is supported by means of a shaft 2| on a frame 22. .The wire netting is 35 supported adjacent the breast roll 20 by means of a plurality of tube rollers 24 suitably supported in bearings provided therefor in the frame 22.

Between the front edge of the fioor of the stock box and the breast roll is a space filled 40 by means of a scraper 25,,composed of rubber with a metal plate 26 embedded therein to give to the scraper proper rigidity. The front part 21 of the scraper has no metal plate therein and engages the wire netting on the breast roll in 45 substantially horizontal alignment with the hori-- zontal radius of the breast roll.

As this breast roll rotates clockwise the scraper cleans the surface of the wire supported and moved thereby, and also provides a slight pocket 50 so that the amount of surface of the wire in contact with the stock is increased, and also so that any wearon the edge of the scraper is compensated by a tendency of the edge of the scraper to move upwardly, due to the rotation 55 of the breast roll and the movement of the wire screen thereon. By this means there is assured a close engagement between the scraper and the wire netting on the breast roll. f

In the stock box is a plurality of stirring drum 28. These drums 28 have holes 29 in the peripheries thereof, and the drums are supported by means of radially disposed plates 30 on an axle 32. Each radially disposed plate has therein a plurality of holes 3| so that the stock may pass through the holes and be thoroughly stirred and agitated.

In the form shown in Figure 2 the drums and the radially disposed plates are supported on the shafts so they may rotate at different speeds, or the plates may rotate in a direction opposite to that of the periphery of the drum. In this,

form the independently rotated radial plates are indicated by the numeral 33 and have holes 34 therein through which the stock may pass for the purpose of being agitated. These plates are supported for rotation on the shafts by means of hubs 35. In front of the front wall is a second auxiliary stock chamber formed by side walls 36 and a front wall 31, which does not extend all the way to the wire netting.

There is provided a transversely extending shaft 38 supported by means of loops 39 on standards 48. 4| for receiving a bolt 42 by which the loops may be adjusted longitudinally of the paper machine so that the shaft 38 may be adjusted. To one end of the shaft. 38 is attached one end of an arm 43. The other end of this arm may be adjusted by means of a shaft 44 provided with a hand wheel 45 for that purpose. By operating the shaft 44 the arm 43 is moved atone end so that the shaft 38 will rock or rotate on its supports. It is to be understood that there'may be two of these arms, one at each end of the shaft 38.

To this shaft 38 there is attached a plurality of arms 46, each arm being attached at one end to the shaft while its other end is connected to an angle iron 41 in any suitable manner. These arms 46 and the angle iron attached thereto support the rear end of an apron 48, which is attached at its front edge 49 to some suitable part of the shaft 38 by means of stay bolts 50. Each of these bolts is attached at one end to the rear of the apron, while its other end is connected to the angle iron by means of nuts 5|.

Extending downwardly from the rear end of the apron is a plate 52, which has on its upper edge a plate 53 adapted to engage the lower edge of the front wall 31. Just in front of the plate 52 and extending downwardly from the rear end of the apron to a point slightly below the lower edge of the plate 52 is a slice 54. Thev stay bolts 50, the plate 52 and the rear end of the apron are joined by means of plates 55 and a transversely extending rod 56.

Extending from the scraper 25 along the periphery of the breast roll, and forwardly along the top of the wire screen at each edge thereof, is a guide 51 adapted to guide the stock as it moves forwardly on the wire screen. These guides terminate adjacent deckel straps 58, one at each edge of the wire screen and supported by rollers 58. These rollers are supported and operated in any suitable manner. The slices may be adjusted independently of each other. The slice immediately above the breast roll may be adjusted from end to end by means of the hand The loops 39 have in each end a slot wheels l1, and it may be adjusted as a whole by means of the eccentrics on the shaft 1.

The slice 54 may be adjusted independently of the slice l8. In operation the slice 54 is usually spaced from the wire netting a shorter distance than the slice l8, but the slice 54 may be elevated out of operative position so it can be used. By means of the slice 54 and the side walls 35 there is provided an additional stock box in which the stock may accumulate between the two walls.
