PULP-FEEDER FOR PAPER-MAKING MACHINES.
To all whom t may concern.'
Be it known that I, DANIEL A. DILLMAN, a citizen of the United States, residing at Oregon City, in the county of Clackamas and State of Oregon, have invented certain new and useful Improvements in Pulp- Feeders for Paper-Making Machines, of which the following is a Specification.
In the manufacture of paper the pulp is generally fed to the machine from what is commercially known as a stuff-box. This stuff-box is subdivided into three compartments which are in communication with one another and with the paper machine and the Source of supply of the pulp stock. In the operation of paper machines supplied with pulp from a stuff-box the thickness of the paper varies which is due chiey to the unequal feed which in turn is attributable to the variation in the density of the pulp.
The present to insure the production of paper of uniform thickness and to automaticallycontrol thevfeed of the pulp' to the paper making machine, such -feed being automatically controlled by the variation in the change of level of the pulp in one of the compartments of the stuff-box.
A further purpose of the invention is the provision of means which may be set according to the nature of the work and which after being set operates automatically to control the delivery of the pulp to the paper making machine so as to insure the production of paper of uniform thickness.
With these and other objects in view,
4which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly claimed.
In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications `within the scope'of the invention as claimed 'may be resorted to when desired. i
Referring to the drawings z-Figure 1 is a perspective view of a stuff-box such as generally used for making machine, such. box being provided Specification of Letters Patent.
invention has for its objectv feeding pulp to a paper Patented Dec.. 2%, i915.
Application led March 6, 1915. Serial No. 12,609.
is a view of details of the attachments for gate N.
Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.
The box in its general formation is of ordinary construction, such as usually provided for feeding pulp stock toapaper making machine. The box comprises three compartments" A, B and C. A pipe D communicates with the bottom of the compartment A and connects with a source of supply of the pulp. A pipe E connects with the bottom of the compartment C and like-- wise connects with the source from which j the pulp is supplied, A pipe F connects with the bottom of the compartment B and serves to convey the pulp` in measured quantity to the paper making machine. The pulp is supplied to the receiving' compartment A and passes therefrom to the feeding compartment B through an opening 1 formed in the lower portion of the partition 2separating the compartment A from the compartment B A gate H is adapted to close the opening 1 and may be opened to a greater or less extent to regulate the flow of the pulp from the compartment A into the compartment B. A stem 3 extending upward from the gate H is threaded at its upper end and receives an adjusting nut J by means of which the gate is opened more or less and held in the adjusted position. The partition 4 separating the compartment A from the compartment C terminates a short distance from the upper edge of the partition-2, thereby providing for an overflow of surplus pulp from the compartment A into the compartment C, such surplus pulp returning through the pipe E tothe source of supply.
In accordance withthe present invention a by-pass R connects the lower portion of I j through the feedin y gortion o? gular space'is formed between .the adjacentI walls 'of thecompartments by-passfR extends across Athis angular space and any surplus pulp passing into the feedvand tovone side of the fee B andy C. The
ing compartment' B515 discharged therefrom ly-pass .R into the overflow compartment? A gate N controls the byl s pass Rand is-'preferably arranged within 15 j which the bye-pass connects. A rim 5 surthe compartmentl B close' to the side with .v rounds the opening formed in the side of the compartment in'line with the by-pass Rand extends a short distance into the com partment andthe gate N is seated against such rim and is spaced from `the adjacent wall of the compartment thereby. The
' gate N has a stem 6 which fis adjustably connected at its upper end with a lever 7,
the latter being mounted upon a standard- L and provided upon its opposite end with a float K. An adjusting nut M threaded upon the end of the stem 6 serves to adjustably connect'the gate with the lever 7.
A nozzle 8 is arranged todeliver a jet of Water into the space` formed between the gate N and the adjacent Wall of the compartment B to prevent pulp collecting in the rear of the gate andA interfering with its freeanovements.
:A collar G is -fitted to the upper endl of the pipe F and may be adjusted vertically to @any determinate height'with reference to' the receiving end of the by-pass R sothat it may be set to regulate. the feed of the pulp to the paper making machine. The collar f G may be held in place by friction or in any manner to insure its retaining the position to which it may be adjusted.
' v. andfis dis partment so las to be acted upon ing movement to the gate The iioat K may be of any construction ose'd a'bove the receivin ythe pulp therein. As the level^of the. pulp the receiving. compartment A changes according to the supply and delivery the float correspondingly rises or falls and through the -lever-7 and stem 6 imparts a correspond- N, thereby regulatingthe receiving 4opening of the by-pass R and controllin l plus pulp from. t e feeding compartment B into the overflow compartment C. By` mov- Af ing the float uponf. the-lever 7 or changin the fulcrum ofv such lever the movement ol the gateN may be regulated. In the' operation of the stuff-box the pulp entersr the receivlng compartment A by way of the pipe- D and passes vinto the. feedlng compartment B throughthe opening 1 thenceA to the papermachine through the the discharge of the sur-l l pipe The gate ,n is sa so that the `inap' enters `the compartment A'.faster vthan it leaves such compartment through the opening 1 and as a result the compartment A soon lls and overiiows into the compartment C the Surplus p ulp returning 'to the source of suppl through the'pipe E. When the densityo7 the pulpjvaries from Yany cause the level of the pulp Ainthe compartment A rises 4or falls, thereby causing a .corresponding movement of the float K and which vmovement is transmitted tothe ate N throu h the connections 6. and 7. en the leve of the pulp in the tank A rises thereby causing a greaterv amount of pulp to pass through the` opening 1 into the compartment B the gate N is lowered by the rising of the float K, thereby permitting more pullbto pass from the feeding compartment through the 'by-pass R into the overflow compartment C, such 'increase in the overflow bein proportionate to the. ad- Vditional supply wlth the result that the feed of pulp to the paper making machine is practicallyk uniform, thereby insuring the production of. paper of even thickness.-
The float` K is preferably hollow and of cylindrical form and is adaptedrto receive `a liquid whichchanges its level according \to the relative position of the iioat-with the result that the effective weight varies according to the inclination of the float and. the level ofthe pulp. Whenl the pul is. 'medium the weight ofthe liquid in the goat is uniformly distributed. When the pulp is thick or dense the excess ofv liquid' occu-` los pies'a position at the inner end of the float partm'ent-B with which the by-pass R connects.- .The stem 10 of ates in the ide 11.
