SAVE-ALL.
Application filed August 8,
To all whom it may concern:
Be it known that I, RALPH S. CLARKE, a citizen of the lnited States, residing at East \Valpole, in the county of Norfolk and State of Massachusetts, have inventednew and useful Improvements in Save-Alls, of which the following is a specification, reference being had to the accompanying drawings, forming part thereof.
This invention has reference to improvements in that class of save alls for paper and similar pulp in which the pulp carried by water is delivered to a tank or vat provided with a traveling pulp gathering surface or means which takes u pulp from water in said vat andcarries said pulp to a point at which said pulp is discharged or released from said traveling means.
In apparatus of the nature herein referred to the efficiency of the pulp gathering operation depends somewhat upon the height of the pulp carrying water in the vat as related to the speed at which the pulp gathering means or element is operated, and, therefore, an important object of this invention is automatically to control the speed of such means or element by mechanism adapted to be affected by the water in said vat.
Another object of the invention is to provide an improved driving mechanism for the pulp gathering members of save alls.
Other objects of the invention will appear from the following description.
The invention consists in such novel features of construction and combination of parts as shall hereinafter be more fully described and pointed out in the claims.
Figure 1, represents an end view of the improved save-all, parts beingbroken away. Fig. 2, represents a side view of the same parts thereof being broken away. Fig. 3, is a detail sectional view on line 33 Fig. 1.
Similar characters of reference designate corresponding parts throughout.
As shown in the drawings 5 designates a vat of suitable construction and having the supply inlet 6, the waste delivery channel 7 and the pulp receiving compartment 8. lxtending into said vat 5 is the water supply pipe 9 which has the arms 10, 10 communicating with the shower pipe 11 the orifices of which are adapted to direct streams of water toward the pulp compartment 8. The pulp gathering cylinder 12 is of the Specification of Letters Patent.

1916. Serial No. 113,819.
usual construction for the purpose of its use having a peripheral wall furnished with a multiplicity of small openings through which water may drain from the exterior of this cylinder to its interior while particles of pulp may be retained at the exterior of the cylinder wall. This cylinder 12 has the frames or members 13, 13 mounted on the tubular shaft 14 which rotates about the axis of pipe 9 and has, exterior of the vat 5, the rack 15. The spaces between the ends of cylinder 12 and the end frames of the vat 5 are closed by the usual packing strips as 16 shown in Fig. 3.
Journaled in a bearing at one end of the vat 5 is the shaft 17 having the belt pulley 1S and the gear 19 which meshes with and drives the rack 15. This pulley 18, under certain conditions, is driven by the belt 20 which is operated by the pulley 21 of the drive shaft 22 journaled in suitable bearings and adapted to be driven in any suitable manner.
When the water and its sustained pulp rises in the vat 5 it will be evident that an increasingly larger portion of the cylinder 12 will be immersed and will receive a corresponding extended layer or accumulation of pulp. It is also evident that the efficiency of the machine will depend to some extent upon the rapidity with which such pulp is carried around by the rotation of cylinder 12 to the point at which such pulp is discharged from said cylinder by the action of the jets of water from the pipe 11.
When the water and pulp is supplied to vat 5 faster than the pulp is removed from cylinder 12 the pulp gathering on the periphery of said cylinder obstructs the flow of water through the interstices of said cyli der to the interior of said cylinder and, hence, toward the outlet 7 of the vat 5. The result of thus obstructing such flow of Water is that the water level at the inlet side of cylinder 12 is raised until such rising water acts to raise and carry upward the float 29 which, acting through its rod extension 28 on the lever arm 27 of sleeve 26 causes the rotative movement of said sleeve 26 and the swinging of its arm 25 to effect the taking up of slack in the belt 20 by pressure thereon of the take-up pulley 23 whereby said belt 20 acts to drive the pulley 18 and, through said pulley and its related mechanism, the cylinder 12 at a higher speed so that the pulp gathered on said cylinder 12 is carried forward more rapidly to its point of discharge. As the supply of water and pulp to the vat diminishes the level of water adjacent the float 29 is lowered and said float falls with the water with the result that the belt-take up pulley 23 is moved in the release direction.
While I have, herein, shown and described a specific construction of my new invention Copies of this patent may be obtained for five cents each, by addressing the it is not thereby my intention to limit my invention.
Having thus described my invention I claim as new and desire to secure by Letters Patent 1. A save-all of the nature described comprising a vat, a pulp gathering member in said vat to carry pulp toward a point of discharge, means to operate said member, and means governed by the supply of pulp and water to control the driving action of said operating means.
2. A save-all of the nature described comprising a vat, a pulp gathering member in said vat to carry pulp toward a point of discharge, and dividing the inlet side of said vat from its pulp discharging point, means to operate said member, and means governed by the level of pulp and water at the inlet side of said member to control the driving action of said operating means.
3. A save-all of the nature described comprising a vat, a pulp gathering cylinder rotatable in said vat, means within said cylinder to direct jets of Water through the cylinder wall at a predetermined point of discharge, means to drive said cylinder, and means, governed by the quantity of pulp and water at that side of said cylinder removed from said point of discharge, to control .the speed of said cylinder driving means.
4. A save-all of the nature described comprising a vat, a pulp gathering cylinder rotatable in said vat, a belt operated mechanism for driving said cylinder, a take-up pulley for said belt carried by a lever arm, and a floatlocated in said vat and having an arm connected to operate said lever arm with relation to the rise and fall of said float with liquid in said vat.
