PAPER-MAKING MACHINE.

Application filed May 18,

My invention relates to paper making ma chines.

It is the object ofmy invention to provide a slice and support therefor, which are adjustable in varying positions'in order to permit of an adjustment of a quantity of stock' behind the slice to prevent the. stock being forced out under the slice if the'stock in the stock box accumulates to too great a height in the box.

I have found that, if I can adjust the space behind the slice between the slice and the box, I can control the ejection of the stock under the slice on to the wire.

This is particularly necessary where the speed of the wire exceeds four hundred feetper minute.

Formerly, the slice was not adjustable and the opening from the stock box to the space behind the slice was constant. By my invention, I am enabled to vary the opening from the stock box to the space behind the slice and also vary the space between such I opening and the slice while still confining the stock behind the slice and thereby adjusting its rate of flow beneath the slice.

I am further able to adjust the quantity of and adjusting mechanism.

Referring to the drawings, 1/ is a stock.

box having a bottom 2 and a front wall 3 provided with an opening 4. This opening is adjusted in its size by the slide 5 controlled by the settin screw 6 and wheel 7. The bottom of this s 'decarries a block 8 to which is ivoted at 9 a stock retaining board. 10. This board is adjustably supported at its forward end by a series of links "11*, the upper end of which is threaded 'at 12 for engagement with the worm wheel 13, which, in turn, is actuated by the adjusting hand wheel 14in the usual manner. This stock retaining board ispiv- Oted at 15 to the-slice 16, the lower end 17 of -Figure 4 is a. front elevation of the slices 1927. Serial No. 192,221.

which is adjustably positioned with respect to the wire 18 by the link 19.

This link 19 is threaded at 20 and is positioned by the hand wheels 21 and 22 with respect to the yoke 23. This yoke, in turn, is rotatably mounted upon a shaft 24 mounted in an eccentric 25. This eccentric is surrounded by an eccentric strap 26 carrying a gear 27 actuated by the worm 28 carried on the shaft 29 which is operated by the hand wheel 30. I,

The wire is carried on the breast roll 31 while the stock box is mounted upon the support 32. The bracket 33 carries the apron 34.

The bracket 33 is attached to the breast roll and vibrates with it so that the apron 34 vibrates with the Wire in unison therewith.

The stock box has a depression formed in the forward end thereof designated 35 in which is located the perforated distributing roll 36 so arranged that the stock must pass through the roll thus insuring an even spread of the stock and absolute prevention of thumb spots and lumps.

By providing a pluralit of adjusting members 20, it is possible to ex the thin slice 16 so as to secure uniform thickness of sheets crossing the machine. The hand wheel 14 effects the simultaneous adjustment of the stock retaining board 10. A stationary apron 37 is-mounted on the bracket 38 which forms a loop beneath the exit opening 4 of the stock box. This apron is superimposed upon the adjustable apron 34 carried on the bracket 33. This apron is adjusted by the handle 38' operating the shaft 39 which is controlled by the ratchet 40 and ball 41.

Method of operation.

' The stock will flow through the opening 4, the exact size of which may be determined by adjusting the position of the slide 5. If, the stock is being forced'beneath the slice at 17 too rapidl due to the accumulation of the stock in t e stock box, I can lift the stock retainin board 10 and position it in the manner indicated in Figure 2 leaving an enlarged space foigthe accumulation thereof. It is "also possible to adjust this board across the machine by more than the single rod 11 so as to adjust the space where the quantity of the-stock is issuing at that particular point. The same is true of the rods 19 of which there may be a number fitting'in a plurality of supporting brackets 23, all being supported in a common shaft 24 operated by the common eccentric 26.

Independent adjustments are carried out by the hand wheels 21 and 22. If it is desired to allow more stock to come out in keeping with the greater speed of the machine, then the slide 5 may be raised as in Figure 3 and the stock retaining board lowered. By these adjustments I am enabled to secure across the entire width of the wire uniform paper without flowering.

I find that this apparatus of my invention is particularly important when the wire speed exceeds four hundred feet per minute, as this high speed will bring about irregularitics in feeding unless I provide some means of adjusting from time to time the pull of stock after it has issued from the stock box directly adjacent the slice, as the mere adjustment of the slice position with respect to the wire will not be suiiicient for this purpose, as such adjustment has another function entirely.

It will be understood that I desire to comprehend within my invention such modifications as may be necessary to adapt it to varying conditions and uses.
