Specification of Letters Patent No. 15,852, `dated. October 7, 1856.

To all 'whom 25 may concern Be it known that I, ISRAEL KINSEY, of Hohokus, in the county of Bergen, State of `New Jersey, have invented a new and useful `Mode of Regulating the Feeding of Pulp feeding chest of any convenient dimensions.

a is a slide operated by the screw b to regulate the opening of the discharge aperture atp.

n is a scale.

B Fig. l is a float connected by the rods (Z and e and the lever C with a valve formed of a conical plug and a cylinder, as shown in nearly full size at Fig. 2; the cylinder is placed in the receiver D Fig. l its top edge being level with the bottom of receiver, the` form of theplug causes a great difference inthe aperture with a very slight movement of the float. y

rlhe pulp passes from the grinder into the vat E, (commonly termed the stuff-chest) in which is a stirring apparatus `(technically termed a hog)- to equalize the consistency of the pulp; this is in common use in` all paper mills, to this stuff chest- E an airtight receiver D is attached and has an open connection with the bottom of the stuff chest E, a tube g is inserted through the top of the receiver D, through which the valve rod e passes to the valve at the bottom, the pulp of course standing at the same height in g as in E.

The feed has hitherto been direct from the vat or pulp chest E and required constant watch and attention to enlarge by hand the aperture of discharge as the decrease of pulp in the chest lessened the hydraulic pressure,unre1nitting care alone enabled the operator to produce paper of a tolerable uniformity of the thickness and weight. By the interposition of the supply chest Awith the float and valve all the watch., care and trouble are` entirely obviated, an equal pressure at the discharge aperture p is obtained and paper of a uniform thickness and weight can be continuously made `with an ease and certainly hitherto unknown.

I propose to use graduated weights in the float as a part of the means of regulating the dow of pulp. l

What I claim as new and desire to secure by Letters Patent is:

Regulating the flow of pulp for making paper upon the web or cylinder of the paper machine, by the pressure of the pulp in a box A receiving its supply of pulp fro-1n the stuf-chest E through the aperture `y in the` trunk D and discharging it through an adadjustable aperture p, below the surface of the pulp in the box A; the pressure being regulated and kept uniform by the height of the pulp 7L in the box A, which is adjusted and maintained by means of a valve e', fitting the aperture f, operated by a float B substantially as described; the combinatio-n of the several parts forming a self-ach ing regulator for the purpose of making paper of equal thickness.
