STOCK REGULATOR FOR'PAPER MACHINES.

' Application filed November 22, 1920. Serial No. 425,777.

Be it known that I, ALBERT T. HILAMAN, a citizen of the United States, residing at Newark, in the county of New Castle and State ofDelaware, have invented certain new and useful Improvements in Stock Regulators for Paper Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved stock regulator for a paper machine and one object of the invention 'is to provide a regulator having'improved means for movably mounting a hopper receiving the stock; from a conveyor spout and improved means for operating a closure at the'inlet end of the spout, the actuating means for the closure being connected-with the suspending means for the hopper so that when the hopper moves vertically, the closure may be opened or closed accordingtothe direction in which the hopper moves.

. Anotherobject ofthe invention is to so construct the supporting or suspending means for the hopper that the hopper and a predetermined amount of stock, may be counterbalanced and the hopper'thus-permitted to move upwardly or downwardly according to whether the amount of stock in the hopper'is more or less than the predetermined amount. I

Another object of the invention is to so connect the actuating means ofthe closure with the suspending means of the hopper that the door may be normally held open a predetermined amount and then closed or opened to a greater extent than the hopper moves. 1

Another object of the invention is to so construct this attachment that it may be used in connection with a conventional type of main'box or stock chest and thus per: mitted to be used in connection with stock chests already in use.

This invention is illustrated in panying drawings, wherein: I

Figure 1 is atopplan view of a stock chest having the improved regulator asso-' ciated therewith. I o v i Figure 2 is a vertical sectional vlew taken along the line 2'2of Fig. 1. l y t Figure 3 is a sectional view taken along the line 3-3 of Fig. 2. I

the accom- The main box or stockchest 1 is divided by partitions 2 and 3 into an inlet chamber 4, a discharge chamber 5, and an overflow chamber 6, the inlet'chamberahaving an inlet 7 5 the discharge chamber an outlet 8,

and the overflow chamber an outlet 9. e The partition 2 is provided with an opening 10 to permit communication'between the inlet chamber a and the discharge chamber 5 and a conductorspout 11 leads from this open.- ing 10 and is provided with a downturned free end portion which is closed by means of a head 12 and provided with side openings 13 through which the stock will pass.

A door or closure 14 is hingedly mounted in the inlet end ofthe spout 11 for closing the opening 10 and this door is provided with an actuating rod 15 which extends through an opening 16 in the spout 11.

A hopper 17 which is conical and open at its lower and upper ends is positioned in the discharge chamber, beneath the outlet end of the spout 11' andprovided at its upper end with an outstanding collar 18 having.

openings formed therein to receive *the hanger rods or bolts 19.v These rods 19 extend through openings formedin the pan 20 positioned beneath the lower end of the hopper and forming a'closure for the lower end of the hopper and further forming a battle which will control the passage of stock out of the hopperwhen the device is in operation. This hopper is positioned as shown in Fig. 2 and a water pipe 21 extends down into the discharge chamber and carries a circular spraying head 22-which is positioned about the outlet end portion of the spout 11 within the upper portion of the hopper so that the water from the spraying head will besprayed upon the walls of the hopper and thus permit the stock to be washed out'of the hopper. t

In order to suspend the hopper there has been provided a frame having crane arms 23 which are mounted, upon aroclcer sh aft 24 journaled in the bearing brackets 25 secured to the walls of the discharge chamber. These crane arms extend above the inlet chamber and carry weights 26 which are adjustably mounted and held in place by set screws 27 so that the weights can be properly placed. The crane arms have their end portions above the discharge chamber forked and pivotally connected with hanger rods 28 which are secured to the hopper by rivets or other suitable fasteners and will thus cause the hopper to be suspended in a vertical. position beneath the outlet end of the spout. A cross bar 29 extends between the crane arms 23 and has its end portions journaled in bearingplates 30 which are secured by bolts or other removable'i'asteners which pass through slots 31 formed in the crane arms. The actuating rod 15 extends through an opening formed in the cross bar 29 and winged nuts 32 are carried by the actuating rod for engaging the upper and lowerportions of the cross bar and thus securely but releasably holding the actuating rod in a set position. It will thus be seen that by releasing the fasteners for the bearingplates, the cross bar maybe moved longitudinally of the crane'arm and the door thus placed in the desired position with the hopper suspended at the properpoint of elevation.

hen the hopper is'in use, it will be filled to a certain extent with the stock and in order to permit the hopper to be properly counterbalanced and yieldably held at a predetermined point of elevation, there has" been provided an addition to the adjustable weights 26, a weight holder 33 which is carried by aline 3 1 which line passes over a pulley wheel 35 carried by the brackets 86 and is then carried over the inlet chamber 4: and connected withthe upper end of a substantially V-shaped lever or turning handle 37. This turning handle or lever has its arms provided with hearing heads 38 which fit upon the rocker shaft 2& and will be secured by set screws 89. By placingthe proper number of weights 40 upon the weight holder 33, the hopper with a predetermined quantity of stock therein may be counterbalanced and held'at the proper point of elevation. If the amount of stock in the hopper falls below the desired amount, the hopper will be drawn upwardly and this will cause the rods 15 to draw upon the door and thus swing the door open to permit a greater quantity of stock to pass through the spout 11. If on the other hand, the stock'is flowing into the hopper faster than desired, the hopper will be filled beyond the desired amount and this will provide sufiicient weight to cause the hopper to move downwardly. lVhen the hopper moves downwardly, the rods 15 will force the door 14 towards a closed position thus cutting off the flow of stock through the opening 10 and preventing the stock from feeding too rapidly through the spout. It will thus be seen that the stock controlled device, will be automatic in its operation when the cross bar 29 and rods 15 are adjusted to the proper point and the weights 26 have been adjusted upon the extended end portions of the crane arms and the proper number of weights placed upon the weight holder 33. By proper adjustment of the rods 19 through the medium of the winged nuts &l, the tray 20 can be positioned the desired distance away from the open lower end of the hopper and the stock permitted to flow freely or be restricted in its flow. A stock control has thus been provided which is simple in operation and which can be associated with stock chests of a conventional construction already in use.

A stock regulator comprising a tank having a partition therein dividing the tank into a receiving compartment and a dis-' charge compartment, the partition having an opening for communication between the compartments, a spout leading from the opening and having a closed end provided with side openings, a rocker shaft extending above the partition, weighted crane arms carried by said; rocker shaft, a supporting rod extending between the crane arms and adjustably connected therewith, a closure for the opening in the partition hingedly mounted in the spout, an actuating rod engaging the closure and adjusta'bly connected with the supporting rod, a hopper positioned in the discharge chamber beneaththe spout and having an open lower end, a pan beneath the open lower end of the hopper, supporting rods for the pan adjustably connected with the hopper, suspending rods for the hopper pivotally connected with said crane arms, and Weighted means connected with the rocker shaft to counterbalance the hopper and contents thereof.
