Berry, Belolt, Wis., asslgnor to Beloit Iron Works, Beloit, Wis., a corporation of Wisconsin Application January 15, 1937, Serial No. 120,733
7 Claims.
This invention relates to a feed box structure for paper making machines which is adapted to be varied in size and capacity to compensate for different types of stock and variable feed demands of the machine when operated at different speeds.
More specifically this invention relates to a stock feed box for a vacuum forming paper making machine wherein an endless forming wire passes around a suction drum with a pond of stock flowing in the direction of travel of the wire.
This application is a continuation-in-part of my copending application entitled Vacuum forming paper making machine, filed September 9, 1935, Serial No. 39,679.
In my copending parent application, Serial No. 39,679, there is disclosed and claimed a vacuum forming paper making machine in which an endless looped wire is trained around a suction drum and a pond of stock is flowed upwardly in an arcuate path against the forming wire as the latter travels around the suction drum. The present application is concerned primarily with the stock feed box which supplies the upwardly flowing pond of stock to the forming wire. This feed box is adjustable in size to compensate for different consistencies of stock which may be used in the machine and to also vary the capacity of the box so that a greater volume of stock may be fed to the wire when the machine is operated at higher speeds. An adjustment of the size of the feed box can also adjust the width of the flowing pond of stock formed adjacent to the traveling forming wire.
It is then an object of this invention to provide a stock feed box that can be varied in size to accommodate different types of stock to be fed from the feed box to a paper making machine and also to increase the capacity of the box for increased stock demand by the machine when operated at high speeds.
Another object of this invention is to provide, in a paper making machine having an endless forming wire trained around a suction drum, a variable sized feed box adapted to supply a pond of stock flowing upwardly against the forming wire for deposit thereon.
A further object of this invention is to provide a feed box for a vacuum type paper making machine which will supply stock to the forming wire of the machine in a constantly flowing pond, the fibers of which arein a hodge-podge arrangement.
A further object of this invention is to provide a stock feed box for a vacuum forming paper making machine such as is disclosed in my copending application, Serial No. 39,679, that is adjustable in size and in capacity and when ad justed automatically varies the size of the pond of stock flowing adjacent to the forming wire of the machine.
Other and further objects of this invention will become apparent to those skilled in the art from the following detailed description of the annexed sheets of drawings which disclose a preferred embodiment of the invention.
On the drawings:
Figure l is a vertical cross-sectional view taken through the stock feed box of this invention and showing the stock feed end of a paper machine in which the feed box is used.
Figure 2 is an end elevational view of the apparatus shown in Figure 1.
As shown on the drawings:
In Figure 1 the reference numeral l0 designates a suction drum having a looped forming wire ll trained therearound. Stock from the feed box of this invention designated generally by the reference numeral I2 flows from the feed box upwardly along the forming wire II as the same passes around the suction drum H) in an arcuate pond P defined by the forming wire H and a somewhat flexible arcuate-shaped metal plate l3. The flowing pond of stock P has some of the fibers thereof deposited onto the forming wire H by suction within the drum I0 and the excess stock flows around over the plate l3 through passageways M which as shown in Figure 2 are on both ends of the plate. The stock from the passageways l4 flows through overflow pipes l5 and may be re-introduced into the feed' box in admixture with fresh stock through a pluralityof feed pipes l6 communicating with the bottom of the feed box I 2.
The distance of the upper end of the plate l3 from the forming wire H can be regulated by adjusting devices indicated generally at H to vary the size of the discharge opening from the pond P into the overflow M. A slice indicated generally at I8 is provided above the forming wire H to dam off the flow of stock and to guide the excess stock back through the overflow out lets l4.
As is more fully described in my copending application, Serial No. 39,679, the arcuate plate I 3 may carry fingers l9 disposed in the pond P for preventing the fibers flowing through the passageway defined by the plate l3 and the forming wire II from assuming the direction of flow of the stock. Rows of these fingers can be adjusted at any desired angle to the flow of stock by rotation of worm shafts in geared relation to shanks oflthe fingers.
The feed box I2 is defined by side walls 2| forming the supporting frame for the feed end structure of the machine. Each side wall 2| carriesIon its inner face thereof a track-. 22 on which is slidably mounted an angle member 23 having a horizontal leg 24 extending rearwardly from the arcuate plate I: and disposed over the track 22 and a vertical leg 25 disposed under the arcuate plate 13. The plate I3 is pivoted to the angle member at 26 and is supported by the angle member.
A rear wall 21 is secured to the side walls 2| and fits under the horizontal leg 24 of the angle member 23.
The frame structure of the feed end of the machine is mounted on a base 28 and a plate 29 on the base 28 forms the bottom of the feed box l2. This plate 29 is provided with openings such as 30 so that the stock feed pipes It can communicate with the feed box l2.
As best shown in Figure 1, stock entering the feed box 12 from the feed pipes 16 passes around horizontal bailies 3| and 32 respectively formed on the rear wall 21 and a vertical bailie wall 33 mounted within the feed box in front of the stock feed openings 30 thereof. The stock then passes over the top of the vertical baille 33 which is spaced from the top'of the feed box and under the vertical leg 25 of the angle member 23 which leg is spaced from the bottom of the box I2. A perforated flow evener roll 34 is provided in the path of the stock below the vertical leg 25 to insure a quiet flow of stock into the pond P.
A wall 36 is mounted on the base plate 29 in fixed relation therewith and extends upwardly to close proximity with the forming wire. This wall 36 may carry a plurality of pegs 31 disposed in staggered relation to aid in preventing the stock fibers from assuming a direction parallel to the flow of the stock.
A shower pipe 38 may be disposed back of the wall 36 for directing a spray of water against the forming wire II as it enters into the pond P to wash the wire and to prevent leakage of stock from the pond.
The angle member 23 can be slid along the track 22, to vary the size of the feed box l2 and also, by carrying the arcuate shape plate l3 therewith to vary the width of the stock pond P, by turning bosses 40 threaded onto bolts 4| which are secured at one end thereof in bosses 42 formed on the rear wall 21 of the stock feed box. Supports 43 having bifurcated fingers or ears 44 are carried by the horizontal leg 24 of the angle member and receive the bolts 4| therethrough. The bosses 40 are mounted between the fingers 44 of the supports 43; In this manner a rotation of the bosses 40 against one or the other of the fingers 44 causes the angle member 23 to slide on the tracks 22 since the rear wall 21 is fixed and the bolts 4| are set in this rear wall. The flexibility of the metal forming the plate l3 permits the plate to be carried with the angle member 23 and thus the size of the pond P can be regulated with the regulation "of the angle member 23 without eifecting the overflow discharge at the top of the plate back ofthe slice l8.
In this manner the capacity;ofithestock feed f box l2 can be varied as desiredto compensate for stocks of different consistencies and at the same time the width of the flowing pond of stock P can be varied in accordance with the variationand capacity of the size of the feed box. Furthermore, when the speed of operation of the machine is increased, the size of the stock feed box can be increased to supply a larger volume of stock to the pond P, while the width of the pond will at the same time be decreased in order to maintain the increased rate of flow of stock in accordance with the increased speed of the forming wire.
I am aware that many changes may be made and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I, therefore, do not purpose limiting the patent granted hereon otherwise than necessitated by the prior art.
