PULP-MILL APPARATUS.

Specification of Letters Patent.

Patented Jan. 7, 1913.

Application filed April 19, 1911. Serial No. 621,980.

To all whom it may concern:

Be it known that I, JOSEPH H. WALLAcE, a. citizen of the United States, and a residentof the borough of Manhattan, in the city, county, and State of New York, United States of America, have invented certain new and useful Improvements in Pulp-Mill Apparatus, of which the following is a specification.

My invention relates to pulp mill. apparatus, and its object is to provide powerdriven machinery for performing certain parts of the process of manufacturing paper pulp which have hitherto been done by manual labor, and to provide intermediate mechanisms and automatic devices in conjunction with and in definite relation to such machines as have heretofore been known in this art by means of which they may be more efl ectively associated with each other and their use greatly facilitated.

I will describe my invention in the following specification and point out the novel features thereof in the appended claims.

Referring to the drawings, Fi ure 1 is a side elevation of a wet machine or making paper pulp, together with a pulp cutting and folding machine. This figure also shows an end view of a tilting table of novel construction, and a portion of a conveyer in section.. Side elevations of the tilting table and the conveyer are shown in Figs. 2 and 3. These figures show the tilting table in difi'erent positions, and illustrate its operation. F i 4'is a plan view of a plurality of units sue as are shown in Fig. 1, and shows the positions in which they are placed relative to one anotherand to a belt-conveyor which is also shown in this figure. In Fig. 5 the same conveyer is shown in plan view together with another parallel conveyor, and between them are shown various devices placed in definite relations to the conveyers and to one another for a purpose which will appear-hereinaf'er. Fig. 6 is a side elevation of some of thedevices which are shown in Fig. 5, and Fig. 7 is a similar View of some other devices which are shown in Fig. 5.

Like characters of reference designate corresponding parts in all of the figures.

1 10 designates a pulp machine of the usual wet types .11 isthe receptacle for the wet pulp stock, and 12 is a rotary cylinder which picks it up and deposits it upon the endless felt 13 which runs over a roller 14 on the end of a pivoted arm 15. 20 is a over a roller 23 onto a shelf 24.

' abl pulp sheet cutting and folding machine of a standard construction. The felt 13 runs through this machine, and the pulp upon it becomes collected upon a roller 21. As soon as a suflicient amount of the pulp has accumulated upon this roller a knife 22 descends and cuts and scrapes it oil". The pulp sheet, guided by the knife, then runs Then a blade 25 descends and forces the central portion of the pulp sheet down between rollers 26, one of which is positively driven so that the folded sheet is discharged from the machine through a slot 27 over a deflecting apron 28. These mechanisms are described but briefly as they form no part of the present invention. They are also illus-' trated more or less diagrammatically, and many of their parts are not shown. Heretofore it has been customary to collect by hand the folded pulp sheets thus formed and to carr them to other devices where they are sub ected to further treatment, thus entailing a large amount of manual labor." I have, iowever, invented the arrangement of parts herein shown for the purpose of facilitating the process of treating the pulp sheets, formed as above described, and reparing them for delivery or shipment. he tilting table 30 which is shown In the dr'awings is so placed that the pulp sheets are discharged upon it. Each of these tables comprises a stationary frame 31 near the upper portion of which is pivoted the table top 32 .which is flanged along its longitudinal edges as at 33. The table top prefercomprises a plurality of transverse r01 ers 34:, and is affixed to a shaft 35 at one side ofits center of gravity and is held in its horizontal position against a fixed stop 36 by an adjustable weight 37.

38 is a sector afiixed to the shaft 35. From a portion of this sector projects a concentric friction member 39 of some soft resilient material such as rubber.

40 is an actuating arm which is pivoted in the frame 31 at 41. A weighted lever holds this arm against a fixed stop 43.

44 is a sector which is referably an integral part of the arm 40 a ove its pivot 41. The curve of this sector is such as to allow it to swing freely under the sector 38.

The weight 36 may be so adjusted that pul sheetshave" been discharged'onto the tab e top 32 the latter will swing into the when one or any other desired number of position in which it is indicated by the dotted line at 32 in Fig. 2. This will bring the friction member 39 into engagement with the sector 44 so that it will arrest the movement of the table top. Now, however, when the actuating arm 40 is moved, the sector 44 which has comeinto engagement with the friction member 39, will cause the table top to be tilted into the position in which it is shown in Fig. 3. Its movement in this direction is limited by stops 45.

50 designates a belt conveyer which runs under the tables 30 and over

rollers

51 and 52 at its opposite ends, and is supported by

intermediate rollers

53, and 54. Movement is imparted to the belt by the roller 52 which is motor driven.

55 is a tripping device afiixed to the upper surface of the belt 50 and so arranged that be seen.

it will engage the lower end of the arm 40 to tilt the table in the manner described so that the pulp sheets upon the table will slide off onto the conveyer. The conveyer belt may be placed higher so that the pulp sheets from the machine 20 will be discharged directly onto it, but it is preferable to use the device shown as the pulp sheets are not then subjected to any strains. Each tripping device comprises a weighted body 56, from one side of which extends an arm 57 which is pivoted to the belt 50 transversely to its direction of movement. When these trips come ,up over the roller 51, their arms 57 become engaged by a fixed abutment 58 and the weighted bodies become thrown over thereby into the position shown in Fig. 2. When in this position they are high enough above the surface of the belt to engage the arms 40. The bodies 56 are heavy enough to remain in this position when they merely swing the arms 40 idly. But if the movement of the arm actuates the table, the added load thus put upon the arm is sufiicient to swin the weighted body 56 back into the osition in which it is shown in Fig. 3.

n this position it is too low to touch the arms 40. y

Referring now to Fig. 4, the manner in which this arrangement is to be used may Here six units placed side by side are shown, each of which consists of a wet machine, a pulp sheet cutting and folding machine, and a tilting table. The conveyer belt runs under all of the tilting tables. The

trips 55 are preferablyspaced at equal dis-- tances throughout the entire length of the conveyer belt along one of its edges. As the tripping devices 55 pass under the actuating arms 40 they merely swing them over without further result until a table is reached which has received its required number of pulp sheets. Such a table will be tilted and the pulp thereon will slide onto the conveyer. At the same time the tripping device which did this will be the pulp which is on thrown over into its inoperative position so that it will not tilt the next tables even if they are already loaded. But the succeeding tripping device will tilt the next loaded table. The result of this will be that piles of the pulp, each with the same number 0 sheets therein, will be scattered along the conveyer, and these piles will not be nearer together than the interval between the tripping devicesa The pulp sheets will then be carried along by the conveyer to the other devices by which they are to be treated.

60 in Figs. 5 and 6 designates a rails along one side of the conveyer and parallel therewith. Spaced at intervals along these rails are the usual presses 61 61 61 and 61 for squeezing surplus water from the pulp sheets. 62 62, 62 62 62?, 62 62 and 62 are trucks upon the rails, one such being provided on either side of each press. 63*, 63*, 63, 63 and 63 are stationary tables near the trucks. These tables are used to support the usual wire or felt separating mats. sheets come forward upon the conveyer, an operator may pile them up upon the truck 62, placing between some of them, at desired intervals, the separating mats from the table 63*. When the truck has received its desired load it may be run into the press 61', subjected to its pressure, and allowed to remain in the press. In the meantime, the truck 62 may be similarly loaded, and then the

trucks

62, 62 62*", etc. After the pulp sheets on the truck 62- have been sufficiently,

pressed in the press 61, the pressure may released and this truck run back to its first position. The loaded truck-62 may then be run into the press 61*. In a similar manner the loaded

trucks

62 and 62 may be run into the press 61, and the other trucks on the rails 60 into their adjacent presses. Another pair of rails is shown at 64 parallel with rails 60. These rails 64 run over scales 65, 65, 65 and 65 Trucks 66 66*, 66

and 66 on these rails 64 are arranged to be moved alongside of the trucks on track 60, or onto the scales or into the baling presses which are designated in the drawings by 6'7 and 67. After the truck 62 has been moved back out of the press 61 to its first position, an attendant transfers the dry pulp sheets from it to the truck 66, taking out or separat' the mats and laying them back upon the table 63. The truck 66 is then run onto the scale 65 for the purpose of weighing it, after which it is ress 67 A where it is 111130 bales. After the pressure is release and the truck 66 is run out of thepress, the finished bale is run out onto the second conveyer 50 which carries it out to a railway-car 68, or to some other desired place for storage or for shipment.

run into the baling pressed and tied u pair of By this novel arrangement of the parts forming pulp sheets, of a power driven belt conveyer, a table positioned to receive the the number of attendants necessary for carrying on this process of manufacture is reduced to a minimum. It will be noted that 5 there are fewer presses for removing the water from the pulp sheets than there are wet machines in operation, and that there are fewer balin presses than there are other presses. All 0 the mechanisms are'placed in definite relation to each other, where they are accessible to the attendants and are so arranged that the diflerent steps in the process of treating the pulp may be carried on with the greatest ease. The conveyer driving mechanism may be stopped at any time by the attendants as devices for this purpose may be placed where they are readily accessible. The arrangements herein shown and described provide means for transferring the pulp sheets through the mill during the process of manufacture without subjecting them while in their soft and easily damaged condition to the rough treatment of being handled by attendants, does away with a large number of the help usually employed, and reduces the cost of manufacture to a minimum.
