Miren rares ArtNr HENRY POHL, OF PATEBSONNEVJESEY.
'lMPROVEiflENT IN MACHINERY FDR MEASURING PULP IN THE NIANUFACTURE OE PAPER.
Specification forming part cf Letters Patent No. 7,/897, daled July 9,1t`i0.
1 0 all 107mm, it may concern.:
Beit known that I, HENRY PoHL, of Paterson', in the county of Passaic and State of New Jersey/have invented a new and useful improvement on a machine for regulating the quantity ot' pulpfor sheetsof paper, to make paper of diil'erent kinds, such as post and drawing paper, Src.; and I hereby do declare viding a movable lid in the regulator-cylinder,
the said lid nbeing operated by a screw to set the lid in the cylinder at any point desired to i regulate the quantity of pulp to be admitted to make sheets of paper of various thicknesses.
The nature of my invention further consists in providing the movable lid with an orifice in it communicating with the pulp-chamber of the cylinder and with the atmosphere by a tube, at the bottom of which tube there is a small cylindrical air-chamber with aball fitting to move up and down to act as a valve, to allow the air to pass out by the tube when the pulp is forced into the cylinder, and to close the tube when the air is all forced out, then to allow the air to rush in when the discharge gate is open, to assist in forcing out the pulp, and to do thisl with the utmost regularity.
To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.
. A is a cylinder to receive the pulp, to regulate the quantity of pulp for different thick-` nesses of sheets of paper, and to regulate the quantity of Vpulp for different sheets of one thickness.
C is the conduit or pipe through which the pulp is directed by gravitation or light mechanical pressure into the cylinder A.
B is the conduit or tube which receives or conducts the regulated or measured pulp from the cylinder, delivering it to the spreading machinery in the common way.
Disthe movablelid of the cylinder, or it may 'be termed a circular head.77
lt is made of any material most suitable, and of suchan area as to lit inside of the cylinder snugly and be moved by the screw up and down toany position in the cylinder. It has a socket in' its center to receive and retain the lower end of the screw G. V
a is a metal bow secured by bolts to the top of the cylinder. It has a' collar, b, with an opening through it to retain the sleeve of the wheel d, which has a thread cut around on its interior, meshing with the thread of the screw which passes through it. By turning this wheel in the proper direction the screw-rod G is wormed up and down, thereby elevating or depressing the lid D.
-E is a small cylindrical air-chamber secured to the lid, which has an opening made in it to" receive the said cylinder. This small cylinder is secured to the lid by screws or by other common devices. On the under side of the lid are secured three bars,y e c c, constructed and arranged under the oriiice through the lid below the small air-chamber, as represented in Figs. l and 3. These bars form a guard for the hollow ball e.
F is a tube communicating with the small air-cylinder E.
H H are the two vertical gates of the conduits B and C. These gates are united by a bolt or any common means to thearms K K, (both alike,) as represented by Fig. 2.
I T" are two revolving cams, which as they revolve act upon the lower ends of the gatearms to lift them up to open the passages of the conduits C B, and to allow the gates to drop down (alternately) to close the said passages. The cam I has a smaller proj ection 011 it than the cam l2. The gate of the discharging-passage B is therefore kept open for a longer period than the gate of the inlet-pas sage. 1 This is common, and need not be further described.
M is the bottom or bed below the cylinder A. discharge-conduit B.
Operation: The gate of the outlet-passage B being closed, the cam l acts upon the arm K and lifts the gate of the inlet-passage C. This passage or conduit is connected by a screw or otherwise to the pulp-reservoir, and the pulp, whichis very thin, immediately iiows from the reservoir through the passage C into that It is made with an inclination toward the part of the cylinder A under thelid D. Then when the cylinder has received the quantity of pulp necessary for the required sheet of paper, the other gate is opened and the inletgate closed, when the pulp in the cylinder nows out and is received on the common machinery for that purpose. As there is a quantity of air Ain the cylinder when the pulp commences to iow in, it escapes through the tube F, past the ball, and ythrough the small airchamber; but when the pulp rises to the ball, it being hollow, (the ball,) it floats up the small air-chamber into its seat, closing up the aperture of the tube F at. the bottom of it.
When the gate ofthe outlet-passageB is opened, the ball drops down upon its guard-bars, and the air rushes down through the tube F, acting upon the pulp to press or assist it to flow out ofthe passage B. This method of allowing the air to escape and to How in is far superior to cocks or any other plan which has heretofore been employed for this purpose.
The movable lid D is for regulating the quantity of pulp for sheets of different thicknesses. The higher the lid is screwed up the greater the quantity of pulp will flow into the cylinder to make a thicker sheet than when the lid is screwed farther down. The pulp being very thin, the compression of it is very With the difficult, nearly equal to the water which composes the greatest part of it. therefore, is screwed down for gaging the quantity of pulp for a thin sheet, the ow from the reservoir is soon checked independent of the gate, and the inlet-gate is then only closed when the outlet-gate is open to allow the pulp to flow out from the cylinder.
The lid can be elevated and lowered by the screw to regulate or gage the pulp for different thicknesses of paper with great eXactness.
No lid for regulating the quantity of pulp in the same manner, so far as is known to the subscriber, has ever been employed before.
I claim- ,In combination with the measuring-vessel herein described, the adjustable lid D, c'onstructed with an opening in it communicating pulp-chamber inf-,the cylinder and with the atmosphere through the small cylin drical chamber E and the pipe F, the communication being closed and opened by the ball, in the manner substantially as described, for the purposes set forth.
I HENRY PoHL.
