Specication of Letters Patent.

Patented Dec. 25, 1917.

Application led August 13, 1917. Serial No. 185,899.

To all whom z't may concern.'

Be it known that I, MIKE A KAB, a subject of the King off'Hungary, residing at Woodland, in the count of Washington land State'- the following is a specification.

The primary object of my invention is they provision of an automatically controlled de- `gice for stuft' boxes wherebya uniform iow .oftockis provided without requirincr lthe attention of an attendant, the device being easy to manufacture and install and calculated to save expense in operating the plant. A further object of the invention is the provision of a stuff box structure for paper making machines for automatically providing a return to the chest of all surplus stock and thereby relieving any excess pressure at the outlet from the stuff box to the mixin box.

Vith these general objects in view and others that will appear as the nature of the invention is better understood, the saine consists in the novel construction, combination and arrangement -of parts hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the appended claims.

In the drawings forming a part of this application, and 1n which like designating characters refer to corresponding parts throughout the several views,

Figure 1 is a central vertical longitudinal sectional view through the device in its normal arrangement,

j' Fig. 2 is a front elevation of the device,

Fig. 3 is a transverse Avertical sectional view taken upon line III-III of Fig: 1,

Fig. 4 is a top plan view of the device,

Fig. 5 is a sectional view similar to Fig. 1 with the device in its operating arrangement,

Fig. 6 is a vertical transverse sectional view taken upon line VI--VI of Fig. 5,

Fig. 7 is a perspective view of the controlling slide and Fig. 8 is a perspective view of one of the partitions.

Referring more in detail to the drawings, a stuff box 10 is arran ed which is adapted to communicate with t e usual mixing box, not shown, for the stock by means of a spout l1 arranged adjacent an outlet 12' in the front Wall or end 13 of the stuiil box. A

Automatic Stuf- Y partition 14 is arranged within the box 10 extending upwardly from the bottom to about one-half of the height of the box while the outlet 12 is controlled by a/valve 15 pivoted to the forward end gf )2f/rocking bar 16 pivoted to a yoke 17 spanning and mounted upon the stuft' box 10. The valve 15 is guided by means of a plate 18 secured to the inner side of the front wall 13 while a sliding weight 19 is arranged upon a notched re u'ced rear end portion 20 of the rocking lever 16 for assisting in adjustably maintaining the valve 15 in its operative position.

A partition 2l is arranged transversely within the Stuff box 10 rearwardly of the partition 14CA and terminating only slightly spaced beneath the upper edges 22 of the longitudinal side walls 23 of the stu" box and is arranged with a central beveled top portion 24. A doorway is provided in the. bottom of the partition 21 normally covered by means of a slide 26 and adapted to be revtracted when desired by means of a headed rod 27 projecting laterally of the box 10.

A controlling slide 28 is vertically shiftably arranged within the box 10 in fiat contact with the rear partition 21 and is provided with an opening 29 registering with the beveled. portion 24 of tlpe partition 21, a bail 30 being attached to the slide 28 and pivoted as at 31 to the rocking lever 16. A

forward hinged cover member 32 and a rearward hinged cover member 33 is provided for the box 10 having their inner edges substantially in contact with each other when the covers are closed. The forward cover 32 rests upon the beveled upper edge 34 of the slide' 28 While a channel plate 35 is swingingly mounted within the opening 29 of the slide 28 upon a rod 36 which passes through the bail 30 and through guide slots 37 in the sides 23 of the box 10.

The locking plate 35 isA adapted to swing upwardly over the adjacent edge of the cover 32 while a resilient latch 38 is carried by the cover 32 for springing over the plate 35 and retaining the saine in position but permitting the rocking movement at the point of contact between the slide 28 and the cover 32 when the slide is raised and lowered. A slightly curved plate 39 is carried by the forward edge of the cover 33 for overlying the latch 38 and the adjacent portion of the cover 32.

The stock is pumped into the stuff box 10 through the inlet pipe 40 into the space bel tween the

partitions

14 and 21 and when sufby means of the outlet pipe 42 in the bottom ficient stock has been pumped into the box to reach the top of the partition 14, the stock iows over the top of said partition 14 to the outlet 12 and beneath the valve 15 to and through the spout 11. The weight 19 is set for permitting the desired ,flow of stock vthrough the outlet'12 while in the event of pumpmg of an excess of stock into the box 10, the stockV will engage the cover 32 of the box-thereby elevating the cover as Well as the slide 28 and bail30 for tilting the lever 16 partially closingA the valve 15 and maintaining the flow of stock constant through the outlet 12 regardless of the increased pressure upon the stock. This elevating 'of the slide 28 permits the surplus stock to iiovv wall or end 41 of the box 10 for returning of the box to the stock chest 43 suitably arranged beneath the level thereof. The slide 26 may be manually opened by means of the rod 27 when it becomes necessary to further relieve the pressure upon the stock within the box 10. Opposite guide strips 44 are provided for the slide 28 and it will be seen that with the

covers

32 and 33 in their normal closed positions, the stock may readily elevate the cover 32 ,carryingthe cover 33 therewith as well as the slide 28 permitting the return of the stock through the slide opening 29. In this manner, the flow of stock through the outlet 12 will be maintained normal automatically during the operation of the machine and the continuous pumping of the stock into the box 1U through the inlet pipe 40 from the stock chest 42.

What I claim as new is 1. An automatic controlling means for the stu box of a paper'making machine, comprising in combination with a stul" box havmg an outlet in its forward wall, a controlling valve for said outlet, partitions within the box forming receiving' and discharging compartments therein, an inlet for stock into one of said compartments and an outlet from the adjacent compartment, a controlling slide between the said compartments, associated hinged lids for the box operatively connected to the said slide adapted Afor opening simultaneously with the opening of the said lids, and operating connections between the lsaid valve and slide.
