HOWARD PARKER, OF BELLOWS FALLS, VERMONT.
.:Y-.; '-PAPER-IMAKING MACHINE.
SPECIFICATION-forming part of Letters Patent No. 700,553, dated May 20, 1902. Application filed September 19, 1900. Serial llmBOfiOQ. (No model.)
Be it known that I, Hownan BAR- ER, a citi: zen of the .United States of-America, and a, resident of Bellows Fa1ls,,in the county of Windhamand State of Vermont; (having. a post-office address at Bellows Fal1s,Ve'rm0 n,t,) am the inventor ofcertain new and useful Im:
v provements in Paper-Making Machines-of I is being formed upon'any'suitable interstitial which, the following is a full, clear, and eX- act description, whereby anyone; skilled in the art may make and use the same.
My invention relatesto paper-making machines, and more especiallyiothe specific parts of such machine wherethe-moistureis partially withdrawn from the-pulp while: it
paper-former, as traveling. paper-making molds or endless paper-making Wire Webs-or H r 'sired,'.and thus'forming'a convenient means aprons.
The object of myimprovementis to provide more efficient meansforwithdrawing the .water or moisture from gthe pulpby securing a high degree of vacuum in what may be called a suction-box and 'at the-same time to;pro-. vide such an apparatus as willrobviate much of the wear of the aprons, screens;- or felts upon which the pulp'iscarried- I 4. r Prior to my invention suction boxes have been commonly used on machines of this class, andin all cases, so far as Iknow, the suo'-. tion-boxes are substantially stationary with relation 'to the movement of I the forming screens or molds.
Figure 1' is a side view of a machine embodying my invention, showing the general relation of the parts. Fig. 2 is a sectional side view of the same. Fig. 3 is a central transverse section showing the stops in .the suction-box andtheir method of operation. Fig. 4 is a detail plan view.
Referring=to the drawings, 1 denotes the frame, which isma de up of the upper part A and the'lower part B The lower part supports the suction-box, and.% the carrier, while the uppersection" supports the driving-gears and the mechanism for imparting a reciprocating motion to the suction-box. The suction-box iis rectangular in form and is mounted on the guides 5 to permit of its having a slight movement crosswise of the machine. Motion is imparted to the box by 'the'link- 6 and the pivoted lever 7, having at its upper end-aroller which travels in the cam-slot 8 'on the end ofrthelshoftjtl. The shaft 9 is driven by the .pulleylO;
. The, top,of thesuotion-box is a perforated plate-11. Under thebottom is the chamber 12,
which opens into the suction-box between the stops'hereinafter described. Pipes 13 extend into this chamber ,12'through stnffing-boxes 14. The pipes13 are stationary and are connected with thegchamber 12 by a slip-joint, thejstufling-boxes 14 preventing the entrance of air around-the pipe intothe suction-chamber. Any water-which is drawn into the suc-.
tion-box fron'rthe-forming-screen will also be icarried 'oif throughpipes 13.
'JW-ithin the j'suctionebox are the movable stops 15for shutting offthe suction from such part-ofithe suction-plate 11 as may be de:
bevel-plates 16?17-. andau intermediate cush? ion 18. The platesjldl? are'connected by a sleevej19,.which is threaded exteriorly and engages one of theplates 17 through cooperat in g-screw-thrads. ,Afrod 20 extends through a stuffing-box 21 into the box, its inner end projecting through the sleeve 19, which con: meets the plates 1617. In the end of this rod 20 is the pin 21 adapted to engage a T- shaped recess'22, formed inthe head offlthe sleeve 19. By engaging this pin 21' with the T-shaped recess 22, as shown in the stop at the left in Fig. 3, the sleeve 19 may be turned, supporting the plates 16 17 andpermitting the elastic-cushion 18 to contract and resume its normal position. The. stop may now be moved bodily to any desired position to vary the active width of the perforated platel11. By turning the sleeve in the opposite direction by means of the rod 20, pin 21%,andT- shaped slot '22 the plates l dlbwill-bebrought together, their beveled surfaces coacting upon the elastic cushion 18, expanding itmntil it crowds against the four walls of 'thefsu'ctiom box, thus providing an air-tight partition across the box. At the outer end of the sleeve 19 is arranged a stuffing-box 23,.which prevents the entrance of air about the rod into the suction-compartment- When the stop has been adjusted to the position desired,-
ICO
the pin 21 may be disengaged from the T- shaped slot 22 and the rod 20 pushed through the sleeve 19, as shown in the stop at the right of Fig. 3. This allows of getting the end of the rod out of the way of the machine operator and is an important feature in the construction of the machine. In connection with this suctionboxIinterpose what maybe called a carrier between the suction-plate 11 and the forming-screen 24:. This carrier is made up of a series of links 25, hinged together, as at 26, forming an endless chain. One of these chains is located at each side of the machine, as shown clearly in Fig. 3. Each pair of links, one on each side of the machine, supports a finely-perforated plate 27, which is firmly secured to them. At each end of the machine the chain of links passes about drums 28, whichare preferably made hexagonal. On the upper face of the links are the teeth 29, which mesh with the gears 30, which are driven by the gear 31, secured to the shaft 9. By this construction the carrier is driven from the two points which move the plates forward always in the same relation to each other. It is clear that should this sectional carrier be driven from one point only the chains would be liable to stretch slightly and produce leakage at the joints; but by driving in the manner above described this objectionable feature is entirely done away with. In order to effectually seal the joints between the plates, I secure to the edges of the plates strips of rubber 32, which when the carrier is passing over the suction-box are pressed closely together, as shown clearly in Fig. 4, preventing any leaking of air into the suction-compartment. It is not necessary to extend these rubber strips the full length of the plates, it being sufficient to have them extend in toward the center of the machine to a point corresponding to the inward limit of movement of the suction-stops, and in the drawings I have shown them extended only part way of the length of the plates.
The contacting faces of the suction-plate 11 and of the carrier-plates 27 are carefully ground, so as to fit closely together and Work smoothly on one another. The forming screen or web which carries the pulp is carried over the suction-box on the above-described sectional carrier, the moisture being extracted from the pulp as it passes over the suctionbox and dropping into the chamber 12, from which it is extracted through the pipes 13. The forming-screens are of very delicate construction, and in the ordinary forms of machines in which they are used they do not last over ten or twelve days. Taking into consideration, in connection with the short life of the screen, its great cost and it is seen that this one step is the most expensive one in the manufacture of paper. By using my invention the strain and excessive wear come on the suction-plate 11 and the strongly-built carricr-plates 27, and the relative movement of the suction-plate and the carrier-plates in a direction transverse to the direction of travel of the carrier continually Wears these parts to a perfect fit.
While I have shown and described the preferred form of embodiment of my invention, it is obvious that other arrangements of parts may be utilized for accomplishing the desired results, and I desire to include herein any such modifications of the apparatus.
I claim as my invention- 1. In combination in a suction apparatus for paper-making machines, a series of links bearing plates and forming a carrier and suc tion apparatus operatively mounted with relation to said carrier and means for driving the carrier and maintaining a positive contact between its several sections as they pass over the suction apparatus, substantially as described.
2. The combination in paper-making mameans for sealing the openings between the plates as they pass over the suction appara- 11.18.
4. The combination in paper-making machinery with the suction apparatus and the traveling forming-screen of a carrier interposed between the suction apparatus and the traveling screen, said carrier com prisinglinks connected in pairs by perforated plates, and a yielding material secured to the opposing edges of said plates, as and for the purposes specified.
5. In combination in a device of the class specified, an endless carrier comprising a series of links and perforated plates, racks formed upon the links, gears for positively driving said links in a fixed relation to each other, and a suction-box operatively mounted with relation to said carrier, substantially as described.
6. In combination in a device of the class specified, an endless carrier comprising a series of links and perforated plates, racks formed upon the links, gears for positively driving said links in a fixed relation to each other, and a suction-box operatively mounted with relation to said carrier, and adapted to have a movement crosswise thereof.
