UNITED STATES PATENT OFFICE.
LOUIS A. DU GKETI, OF GHENEYS STATION PENNSYLVANIA.
IMPROVEMENT IN STUFF-REGULATORS FOR PAPER-MACHINES.v
Specification forming part of Letters Patent No. 150,515, dated May 5, 1874; application filed February 24, 1874.
To all whom t may concern Be it known that I, Louis A. DUoKETT, of Oheneys Station, inA the county of Delaware and the State of Pennsylvania, have invented a new and' useful Improvement in Stuff-Regulators for Paper-Machines 5 and I do hereby declare the following to be a clear and exact description of the nature thereof, suflicient to enable others skilled in the art to fully understand, make, and use the same, reference bein g had to the accompanying drawings, malring part of this specication, in which- Figure 1 is a side elevation of the device embodying my invention. Fig. 2 is a central vertical section thereof.
Similar letters of reference indicate corresponding parts in the two iigures.
It is important in paper-making that the pulp is fed uniformlyr to the machine, in order to produce uniformity in the paper.
My invention relates to means for accomplishing such results; and consists in a bent tube, one portion of which receives the pulp and contains a iioat, and the other portion communicates with the machine and with an overflow-tube leading to the place of supply, or reservoir, whereby, through the medium of the float, a single gate of the overflow-tube regulates the feed to the machine. It also consists in making the iioat and overflow-gate adjustable relatively to each other. I
Referring to the drawings, A represents a tube, which is somewhat of a U or V shape, openat its two ends, preferably constructed of metal, and properly supported so as to stand upright with the open ends above. B represents the feed-pipe, which opens into the tube A near one of its upper ends, and communicates with the pump of the chest or place of supply of the pulp. In the limb of the tube, above the point of junction of the pipe B, there is located a float, C, to which is jointed a rod, D, connected to one end of a rocking or walking beam, G, whose axis is 011 an adjustable standard or upright, H, which is suitably supported on the tube A, or frame-work properly located. J represents an overiiow-pipe, which opens into the other limb or end of the tube A, opposite to that to which the feed-pipe is secured, and leads back to the pump or place of supply. K represents a gate or valve arranged within the` tube A, so as to cover and i the paper-makin g machinery. M represents a pipe which leads from near the upper end of the tube A, at the part to which the overowpipe is secured, and a similar pipe, N, is secured to the tube below the pipe M, the two pipes communicating with each other, and leading to the paper-making machinery. The openings between the pipes M N andthe tube A will be covered and uncovered by gates P I), which are to be adjusted relatively to the amount of pulp that is to flow from the .tube to the place of usage.
The operation is as follows: The various gates being properly adjusted, the pump is set in motion. rlhe pulp is directed through the pipe B to the tube A, ows down the adjacent side thereof, and then up the other side, thus iillin g the tube.` The escape of .the pulp from the tube A is by means of the pipes M N. As long as there is uniformity in the flow from the pump, the iioat remains passive; but as soon as the iiow increases, then the increased volume bearing against the under side of the iioat causes the latter to rise, whereby the gate K is lowered, and more of its opening uncovered, so that the overiiow is greater, the surplus returning by means of the overilowpipe to the chest or reservoir, where the pump is fed. This prevents an increased pressure or flow of the pulp in its passage to the papermaking machinery. When the ilow from the pulp decreases, the float falls and the gate K rises, thus bringing some or all of the closed part of the gate over the opening of the overiiow, whereby the overflow of the pulp `is checked without causing any check in the iiow of the pulp to the machinery. Thus, in the flow of the pulp to the machinery, there is a uniformity which will be maintained at all times, regardless of any variation in t-he iiow from the pump, or irregularity in the consistency of the pulp.
For heavy and coarse pulp the upper pipe will be employed, in order that the pulp may have more head, and thus iiow freely, the foreign matters that exist therein being permitted to descend to the bottom or bend of the tube. For fine pulp the lower pipe N will be employed, since its tendency is to iiow freely and thus pass out quickly.
S 'represents a gate at the bend of the tube,
whereby access may be had tothe interior of the bend for the removal of any matters that may collect, clog, or interrupt the free passage of the pulp. A gate, T, Will be arranged near the joint of the pipe N with the tube A, for removal of matters that may gather at said point.
The several parts of the regulator may be made of metal, and thus possess strength and 1. The two-limb or bent tube A, the float C,
the feed-pipe B, and the rocking beam G, in combination with the overflowpipe J and its single Valve or gate K, and With the dischargepipe, substantially as and for the purpose set forth.
2. The combination, with the tube A, iioat C, rocking-beam G, and gate or Valve K, of
the adjustable standard H, and adjustable con nection I, substantially as and for the purpose set forth.
Vitnesses: LOUIS A. DUCKETT.
