PULP AND PAPER MAKING lVlACHlNE.
SPECIFICATION forming part of Letters Patent No. 693,896, dated February 25, 1902.
Application filed June 23,1900.
To aZZ whom, it nmy concern:-
Be it known that I, HOWARD PARKER, of Bellows Falls, in the county of Windham and State of Vermont, (having a post-office address at Bellows Falls, Vermont,) have invented certain new and useful Improvements in Pulp and Paper Making Machines, of which the following, when taken in connection with the accompanying drawings, is a full, clear, and exactdescription,wherebyanyoneskilled in the art may make and use the same.
While my invention relates to paper-making machines of the class which form a continuous web of semiplastic form from a stuff properly prepared,it relates more particularly to an improved form of doctor and will be more fully described in relation to the drawings, in which- Figure 1 is a sectional side elevation of my invention. Fig.2 is afront elevation looking from the right of Fig. 1. Fig. 3 is adetail, on
enlarged scale, showing the relation of the. snout of the doctor to the roll.
Referring to the drawings, the letter A denotes the tank, which is of the ordinary construction used-inmachinesofthisclass,having mounted in it a roll B. The pulp heldin suspension jn this tank and in which the roll is partly submerged is very buoyant, and as the roll revolves the particles of pulp will collect of their'own accord on the periphery of the roll and form a more or less compact sheet. Any water which leaches into the interior of the roll may be drawn oif through the pipe 0. If desired, any suitable form of suction apparatus may be employed to gather the pulp onto the periphery of the roll; but for the purpose of clearly describing the operation of my invention herein sought to be protected the roll which is shown and described is sufficient.
Thenovel form of doctor which forms the essential feature of this invention comprises the stack D, connected at its top with a suitable suction apparatus E. Connected with which may lead to another part of the machine, as Where it is mixed with the bleaching" materials, clay, &c., with which the pulp must be treated before it is in proper condition to beworked into the finished product. A snout G of substantially the same width as the roll seriili No. 21,286. (No model.)
form a more or less compact sheet. As this sheet of pulp comes under the snout of the doctor the suction deflects it from tlie'roll and carries it into the spout, where it breaks up and passes through the pipe K, dropping intothe bottom of the stack. The pulp in the stack is in a much more solid condition than when it is in suspension in the tank A, but it is sufiiciently mobile to How out of the pipe F in the direction of the arrows after the stack has been filled to the level of the standpipe, as shown in Fig. 1 of the drawings.
I claim as my invention 1. The combination with the tank partly filled with solution, and the roll adapted to pick up the finely-divided particles of solid matter in the solution, of a stationary doctor operated by suction and adapted to remove from the roll the material collected thereon.
2. In combination, the tank partly filled 'with liquid holding finelydivided particles of pulp in suspension, and the roll immersed therein and adapted to pick up the pulp and form it into a sheet on its periphery, of a doctor operated by suction and adapted to remove the sheet of pulp from the r-oll,and means for delivering the pulp, when so removed, in condition forfurther manipulation.
In a machine of the class specified, the tank partly filled with liquid holding in suspension finely-divided particles of pulp, a-roll revolubly mounted in the tank and adapted to collect the finely-divided particles of pulp l on its periphery, and suctionoperated means the bottom of the stack is the stand-pipe F,
for removing the pulp from the roll, and depositing it in a suitable receptacle, substantially as described.
t. The combination with the tank partly filled with a pulp solution, the roll revolubly mounted in the tank and adapted to pick-up the pulp on its periphery, of a stationary suction-operated doctor adapted to remove the pulp from the roll and deposit it in a receptacle and means adapted to deliver the pulp in proper condition to the next step in the series of operations to which it is to be subjected.
5. In a machine of the class specified the tank, solution in said tank, the roll revolubly mounted therein and adapted to form the finely-divided particles of solid matter in the solution in a sheet on its periphery, and suction-operated'means for removing the sheet of pulp from the roll, for breaking it up, and depositing it in a suitable receptacle.
6. In a machine of the class specified in combination thetank partly filled with liquid holding finely-divided particles of pulp in suspension, the roll revolubly mounted therein, and the doctor having an orifice located adjacent to the surface of the roll and a reduced rear portion connected with a suction apparatus.
7. In a machine of the class specified, in combination the tank partly filled with liquid holding finely-divided particles of pulp in suspension, the roll revolubly mounted therein, the doctor comprising a snout having an orifice along one edge located adjacent to the surface of the roll and a reduced rear portion extending into a chamber, the chamber connected with a suction apparatus and having near its lower end an outlet for the passage.
of the pulp, substantially as described.
