PAPER MACHINE. Application filed October 30, 1919. Serial No. 334,458.

My .invention relates to an improvement is also provided with a false bottom which in paper machines and refers more parcauses the stock entering through port 4 to ticularly to cylinder machines in which the pass down into the bottom of the vat under water is automatically drawn from the the cylinder and below the false bottom in 5 paper stock or pulp after the stock has been the direction indicated by arrows as seen in ca picked up from the vat by an endless wire Fig. 1. The stock is caused to; become thormesh or screen which travels over a cyloughly commingled in the vat and is in-a inder or drum before spreading stock into perfetly homogeneous condition throughout sheets. where it comes in contact with the mesh Among its salient objects is to provide a thus producing an even adhesion of paper 65 machine. in which the stock after being to the mesh. Around the cylinder and thoroughly mixed in a vat is drawn upon a adapted to have continuous motion is a wire mesh surfaced cylinder which is divided mesh 6, a portion of which is at all times longitudinally into compartments; to prosubmerged in the vat. The mesh after leavvide a machine in which said cylinder is roing the cylinder passes over table rolls .7 7 tated past suction pipes arranged at one or and suction boxes 7 and thence to the conch both ends of the cylinder above the surface rolls and thence back over rolls 9- which 1mof the stock in the vat, having mouth-pieces part tension and change direction as may or valve plates to register with the ends of be desired to the cylinder, the travel being the compartments, to complete the suction in the direction indicated by arrows in Fig. chambers; to provide a machine which 1. A deckle 10 of the usual construction is draws the water from the paper stock that is mounted wholly within the vat. This prespread upon the mesh surface of the cylvents the deckle from becoming injured by inder by the use of suction pipes which draw any means outside of the vat and a shower the water from the compartments with the of water (not shown) keeps it clean and successive registering of the compartments free from dirt. with the mouth-pieces of said suction pipes; In Fig. 2, is shown in more detail the conto provide a machine in which the drying struction of the cylinder. It has a series of process is materially shortened, and in genpartitions 11 radiating from the shaft 3 and eral to provide a machine of the character dividing cylinder longitudinally into pockreferred to. ets or compartments 12. These compart- Referenc-e may here be made by my Patments are air tight with exception of that ent No. 923,870, issued June 8, 1909, wherein part of each which is the cylinder facing ora wire mesh travels around and upon the mesh and the ends. As the cylinder rotates cylinder and is carried over a series of drythese compartments, one or more at a time, 90

ing rolls and suction boxes to couch rolls and are capped by the stationary valve plates 13 thence to the presses. My present improveand come into registration with said valve-- ment consists in the construction of the cylplate in such a manner that the ends of said inder used in conjunction with the above compartments are closed airtight except for patent as explained above and is furthermesh cylinder surface and the pipes or out: 5 more and more particularly described herelets 14 in which is formed a suction or parinafter. tial vacuum. The suction through pipes 14:

In the drawings and a similar outlet 15 on the opposite side, Fig. 1 is a side elevation partly in section, materially assists in drawing the water 4 of as much of the machine as is necessary to from the stock which has adhered to the 0 show the application of my invention thereoutside of the cylinder facing, thus hel ing to; to dry the sheet formed on the mesh. ut- Fig. 2 is a front elevation of the cylinder side of the vat is a water reservoir 16 and with parts broken away, to show the form leading from a cylindrical screen thereto of construction whereby the suction may be is a port 17 in the wall of the vat 1, and. applied to the ends of the cylinder. leading from the water reservoir 16 is the In Fig. 1 of said drawings, 1 is a vat for discharge 18. It is understood that this are. containing the stock, 2 is a cylinder mounted rangement may be so constructed that it" in in said vat on a shaft 3. The vat has an inno Way interferes with the forming of a V let port 4 for admission of the stock and it sheet on said mesh when there is no suction applied. In such a case, the cylinder may be used in the ordinary manner, although without the use of the suction-cylinder, a very much smaller quantity of paper can be produced with the same number of drying rollers. A more expensive operation is nec-' essary to dry the sheet if the Water is only partially removed, and this mode of removing a greater part of the water materially accelerates the production of the paper.

Although in the specification I have explained the suction drying device in connection with my paper machine, it is not my intention to limit its use to this particular type of machine, for it can readily be seen that this suction arrangement may be adapted to any type of cylinder machine and attain like results.

I claim as my invention:

1. In apaper machine, the combination with a vat, and an inlet port for introducing paper stock, of a rotatable cylinder aving a series of partitioned walls mounted therein, an endless Wire mesh adapted to travel around said cylinder and means for drawing Water from the c linder compartments above the surface 0t the paper stock in the vat prior to its leaving the cylinder.

In a paper machine, the combination With a vat having a false bottom and inlet port for introducing paper stock, of a rotattable cylinder longitudinally partitioned into compartments, an endless Wire mesh adapted to travel around said cylinder and a suction pipe and valve plate arranged above the surface of the paper stock in the vat to form suction chambers of the cylinder compartments and draw Water from same.

3. In a paper machine, the combination with a vat having a false bottom and inlet port for introducing paper stock, of a r0tatable cylinder mounted therein having a series of partitioned walls radiating from the center of the cylinder and running longitudinally of the cylinder, an, endless Wire mesh adapted to travel around said cylinder and suction pipes with valve plates arranged to cover the ends of cylinder compartments, thereby completing suction chambers for drawing Water from said compartments.

4. In cylinder paper machines, the combination with a rotating cylinder having a sheet forming screen for picking up the paper stock passing thereover and, longitudinally partitioned to form compartments, of a suction means consisting of suction pipes with valve platemouth pieces adapted to register with the open ends ofthecylinder compartments'to form a partial vacuum in suction chambers for from the paper stock.
