2 Claims.

- This invention relates to improvements in paper-making apparatus and is directed more particularly to an improved paper-making machine of the cylinder type.

v The principal objects of the invention are directed to providing a paper-making apparatus which includes a cylinder mould disposed in a vat containing paper-making material and as a special feature the cylinder' is adjustable relative to the walls of the vat so as to facilitate the meeting of the varying conditions and requirements in the manufacturing of paper.

In paper-making apparatuses vof-the type to which this invention relates, a cylinder or cylinder-mould rotates in a vat having Walls and the cylinder is adapted to take on its foraminous surface the libers Aof paper-making material which is introduced into the vat. The cylinder is so formed that the water which has been relieved'of bers may be discharged.

' It hasbeen found desirable in Aorder to produce certain results in the manufacture of paper to have the walls of the vat in a certain relation relative to the cylinder mould. That is to say, it has been customary in order to produce a certain kind of paper to so rotate the cylinder relative tothe vat and so arrange vthe apparatusthat the wall ory Walls of the vat are so spaced from the cylinder mould as to provide or produce paper-making material of a certain desired consstency.

According to this invention, in order to attain certain predetermined results, the wall or walls of the vat may be of a certain shape and size and be located a certain desired distance from the periphery of the cylinder. To obtain other characteristics and results, the spaces between the cylinder and walls will be different, as well as the speed with which the cylinder is rotated.

As will appear, as contrasted with papermaking apparatus heretofore known where the spaces between the cylinder and the walls of the vat have been constant so that the characteristics of the paper-making material have consequently been limited to an objectionable extent, my apparatus is adjustable.

Various other novel features and advantages of the invention will be hereinafter more fully referred to in connection with the accompanying description of the invention, in the present preferred form thereof, reference being had to the accompanying drawing, wherein:

Fig. 1 is a partial plan view of one side of the apparatus of the invention; t

Fig. 2 is a side elevational view of what is (Cl. en 43)v y Y shown'inrFig. 1. lwith parts in section' for clearness;v

Fig. 3 is a sectional plan view on the line 3-.3 of Fig. 2; and

Fig. 4 is a sectionalv plan view on the line 4 4 of Fig. 2. i 1 f i it and the rotating cylinder.

Referring now' tothe drawing more in detail, the invention will be fully described.

A vat has spaced forward and rear endwalls 2 and 4 respectively. Side walls connect these end walls in vat-forming relation.

Only one side of the apparatus is shown in the drawing but it will be understood that the opposite side is substantially similar and therefore need not be described in detail.

The sides of the yvat are formed to have spaced members whichform chambers for the papermaking material and for the Water which is discharged whenthe cylinder has taken on the fibers. In the form shown, this is accomplished by providing an inner side Wall 8 and an outer side wall I0. v

A rotatable cylinder is shown at I2 and this has ashaft i4, having its opposite ends extending out," through` the, inner side walls 8. Within the vat there is a'icurvedbaille-like wall, indicated by llivsrrhich is spaced from the cylinders periphery; 1 Y

In'practice the paper-making lmaterial iiows into the chamber `at one side of the vat and over theV upper end of wall I6 into the space between The latter takes on the bers from the paper-making material, which consists largely of water and fibers, and the water is discharged from the end of the mould.

The ends of rotatable shaft I4 are journalled in bearing members such as 20 at opposite sides of the vat. It will be understood that there is similar mechanism at opposite sides of the vat but since only one side has been shown the following description will be with reference to but one side.

From bearing 20 there extends upwardly a vertical rod 22. 'I'he upper end of rod 22 has spaced ears between which is pivoted at 24 the lower end of a screw or threaded shaft 26.

The screw 26 is in threaded engagement with the hub of a gear 28 which is rotatable in a bracket 30 associated with the vat as shown in Fig. 2. A horizontal part 29 of member 22 has an end portion 21 guided for vertical movements in a guideway provided in bracket 30, such as formed by gibs 3| on said bracket and as shownvmore clearly in Fig. 3.

The gear 28 is in mesh with a gear 29 provided on a rotatable shaft 34 and said gear 29 is rotatable in bracket 30. The forward end of said shaft 34 is journalled in a bearing 36 and has on its forward end a worm gear 38.

In mesh with the Worm gear is a worm 40 provided on the end of a shaft or rod 44 which extends transversely of the forward end of the apparatus. A hand-wheel 42 is preferably provided for rotating said rod.

It will be seen that as rod 40 is turned in one direction or the other it causes rod 22 to move up or down, by means of action through worm gear 38, shaft 34 and its gear, gear 28, and screw 26. Movement upwardly or downwardly of rod 22, of course, brings about similar movement of the cylinder relative to the vats walls since rodv 22 is directly connected to the cylinders shaft 20.

A rod 40 has its lower end pivoted at 42 to member 20 and its upper end is in threaded engagement with a worm gear 44. A bracket 50 is carried by the vat and it has spaced ears, as shown, between which are pivoted at 48 'a bracket member 46.

The latter member confines the worm gear 44' and extending through its lower side is a transverse shaft 52. Said shaft 52 is rotatable and has worms in operative engagement with Worm gear 44.

Preferably, a manually-engageable hand-wheel 54 is provided on shaft 52 for rotating the same. Thus, it'will be seen, as rod 52 is turned in one direction or the other, rod 40 is moved to the right r left, through the worm gear mechanism, so that bearing 20 and the cylinder shaft I4 journalled therein is moved to the right or left.

In this way, the cylinder may be moved vertically as wellas horizontally. Since the hub 46 is swingable, the rod 40' may move in longitudinal planes as the member 20 is moved up and down.

To prevent paper-making material from passing out between the endsof the cylinder and the side walls and into the outletchamber without first having contacted the cylinders foraminous surface so that the latter lmay takepnthe bers, I preferably provide a plateInember 5 0 Aof greater diameter than the cylinder adjacent thewall `8 as shown. Alsoan 'annular packingl such asis indicated byEZvmay be provided. n .e

While I have described the invention in great detail and with respect to the present preferred form thereof, it is not desired to be limited thereto since changes and modifications may be made therein Without departing from the spirit and scope of the invention. The invention may be embodied in other specic forms Without departing from the essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.

l/Vhat it is desired to claim and secure by Letters Patent of the United States is:

l. The combination in paper-making apparatus of, a vat having front, rear and side walls and a curving wall between the lower portions of the side walls, brackets on the upper sides of the side walls, members movable up and down on lsaid brackets and means for moving the same, rods with upper ends pivotally connectedto said members having loWer free ends, journal means at the free 'ends of said rods, a cylinder journalled at opposite ends in said journal means, and means connected to said journal means for swinging said rods and cylinder back and forth relative to said curving wall.

2. The combination in al paper making apparatus of, a vat having front, rear and side Walls and a curving wall between the lower portions of the side walls, brackets on the upper sides of the side walls, members movable up and down on said brackets and means for moving the same, rods with upper ends pivotally connected to said members having lower free ends, journal means at the free ends of said rods, a cylinder journalled at opposite ends in said journal means, oscillatable brackets on said side walls, rods pivotally connected to said journal means having upper threaded ends slidable in the oscillatable brackets, and operating means engageable with said threaded ends of Ysaid rods to move the same in said brackets and thereby act on said journal means. y n
