UNITED STATES LLONZO ALDRICH, '01 BELOI'I, WISCONSIN.
PAPER-MAKING MACHINE.
To all whom it may concern:
Be it known that I, ALONZO ALDRICH, a citizen of the United States, residing at Beloit, in the county of Rock and State of Wisconsin, have invented a certain new and useful Improvement in Paper-Making Machines, of which the following is a full, clear, concise and exact description, reference being had to the accompanying drawings,
forming apart of this specification.
My invention relates to machines for making paper. j
The principal objects of the invention are to provide a simple and practical machine formaking paper, and to produce a machine very much smaller and less complicated than present day aper making machines.
Another 0 'ject of the invention is to secure efliciency, economy and greater speed in operation.
In the accompanying drawings Fig. 1 is a side elevation of a papermaking machine embodying my present invention;
Fig. 2 is a plan view of the same;
Fig. 3 is a view partly in end elevation and partly in cross section; and
. Fig. 4 is a cross section taken on line 4--4 in Fig. 3.
In the drawings I show a machine having a base or body 1, in which is mounted a rotary member 2 in the form of a hollow cylinder. The ends of the member 2 are supported in bearings 3-3 supported on ped-. estals or uprights 44 at the ends of the base member 1. The rotary member 2 is to serve as a paper making element and to such end is made of a perforate construc- 'tion, as for example, by providing it with a plurality of apertures 5- 5 terminating in a series of circumferential grooves 6'6. A series of longitudinally extending rods 7 are laid upon the periphery of the cylinder 2, being preferab y set in longitudinally extendin grooves of about half the depth of the rods 7 so that said rods 7 will project above the periphery of the cylinder 2 only about half their thickness as shown in Fig. 3.
A windin 'wire 8 is wrapped s irally aroundthe cylin er 2 outside of the ongitudinall extending rods 7. Two layers of wire clot 8 and 8 are arranged outside of the winding wire 8, the inner or foundation 1ayer'8' being coarser than the outer layer '8".
tltlOIlS 16-1 6 extend upwardly from the Application filed. November 4, 1921. Serial No. 512,Q11.
As a means for rotating thecylinder 2 I show agear 9 on one end of the same, said gear 9 meshing with a pinion 10 on a rotary drive shaft 11 carrying a driving pulley 12.
A wooden tank 13' is arranged below the cylinder 2 (Fig. 3), said tank having a chamber l3 -for the paper pulp from which the paper is to be made. Within the tank 13 is a horizontal partition 14 through which apertures 15 are formed and vanes or parpartition 14 to close proximity to the under side of the rotary cylinder 2. The apertures l5 and vanes 16are preferably at anin'clination to the vertical, as shown in Fig. 3, so as to give the paper pulp a sidewise movement and thereby cross the fibers in th finished paper.
The pulp chamber or vat 13 is supplied with paper pulp from a tank or head box 17 and the connection 18 extending from the 7 tank 17 to the base member 1 and having I a channel or duct 19 for the flow of ulp material. Circulation of the paper pu p is I secured by a pump 30 connected with a small supplemental tank 31 and also connected with a pipe 32 running back to the main tank or head box 17 and dischargin into the same, the discharge being control ed by a valve 33. The supplemental tank 31 has a gate valve 34 controlling the passage or. duct between said tank 31 and the pulp chamber 13, the gate valve 34 being ad ust able by means of an adjusting screw 35 and wheel 36.
Vacuum boxes 20 and 21 are arranged inside of the cylinder 2 and preferably on the upwardly moving side of the same,.as shown in Fig. 1. These boxes 20 and 21.are susended by suitable means, as for exam le rackets 22, so that the under sides or w ls of the boxes are in contact with the inner surface of the cylinder 2. The brackets 22 are in turn supported by arms 23 secured by bolts 24 to the uprights 4. Adjusting screws 25 adjust the positions of the boxes 20 and 21 and said screws 25 hold the brackets 22 in adjusted positions. The boxes 20 and 21 are connected with pipes 28 by means of branch pipes 29, the pipes 28 running to a suitable blower or other-apparatus for producing a vacuum or partial vacuum so that air is. exhausted from the interior of the boxes and 21 and suction produced therein. The first box 20 draws water from the.
pulp and the pulp against the wire, and so forms the sheet on the "wire. 'The other box 21 draws water through the wire from the sheet to dry the same. lVear plates 13 are bolted to the ends of the tank 13 to keep the paper pulp from leaking out at the ends o'l" the tank under the cylmder. When these wear down, they may be removed and others. put in their places.
A couch roll 38 is arranged abovethe cylinder 2, said roll 38 beingcarried by suitable means, as for example, swinging arms 39-39 pivotedat 40. The roll 38 is made f adjustable in asubstantia'lly horizontal manner relatively to the arms 39 by means of bolts 41 arranged to move in apertures 42 in the arms 39. This adjustment of the roll is controlled by a screw 43 having an end 45 in which the the lower portion of the frame 55.
A belt or band 47 of felt or other suitable material passes around the roll 38 and also over the top of the paper wheel or cylinder 2. This belt or band 47 also passes between pressing or squeeze rolls 49 and 50 adapted or s ueezing moisture out of paper on said ing arms 51 pivoted at 52 and carryin an adjusting weight 53 and the lower rol 52 being mounted in bearings 54' supported Tin e bottom ro1li .50 is provided with a clutch 56 (Fig. 2) and also with the driving pulley 57. The frame 55 is supported on another frame 58 which has arms 59 supporting a roll 60 over which latter the belt or band 47 passes. Another roll 61 is mounted on small pedestals 62 near the base of the frame 58. The beltor'band 47 passes first around the roll 61, thence up and overthe roll 60, then underneath and around the roll 38 and then between the upper and lower squeeze " rolls 49 and 50. The paper which is formed on the wire on cylinder 2 passes from said cylinder 2 on to the felt band 47 passing.
around the roll 38. The paper travels with the belt 47 from the roll 38 to and between the squeeze rolls 49 and 50, by which latter the remaining moisture is squeezed out.
As an arrangement for facilitating the separation of the paper from the wire, on the roll 2, I show a vacuum box 63 on the top of the roll 2, said box 63 being connected by a pipe '64 with some suitable vacuum producing apparatus to create a condition of suction in the box 63.
It will be seen that the machine is more simple and compact and is a great deal smaller" and less complicated than present day paper machines, and it can be run a great deal faster.
sition on the outer side of the rotary formm member and close to the same so. as to exert suction force on the paper strip before it actually leaves the forming member.
2. A papermachine comprising a tank or vat, a rotary member for making paper, said member being mounted to permit its lower portion to be submerged in the pulp in said tank or vat, and the remainder to be unsub merged, means for forming the paper sheet on the submerged portion of sand member, means for withdrawing moisture from the sheet on said member, a roll coo crating with said rotary member to receive tl ie paper sheet from the same, and means tending to remove the paper from said rotary member before it reaches said roll and facilitate its movement on to said roll.
' 3. The combination with a tank or vat and a rotary forming member arranged above the tank or vat with its lower portion immersed in the material in the vat, of a suc-' tionbox on the inner side of the rotary forming member about the level of the material in the tank or vat for farming the film on the rotary member and a second suction box also located within the forming member and above the first mentioned box' for withdrawing moisture from the film. 0
4. The combination with a tank or vat and a rotary forming member arran ed above the tank or vat with its lower portlon immersed in the, material in the vat, of a suction box on the inner side of the rotary forming member about the level of the material in the tank or vat for formin the film onthe rotary member and a secon suction box also located within the forming member and above the first mentioned box for withdrawing moisture from the film, and,
