FEEDING DEVICE FOR PAPER-STOCK.
SPECIFICATION forming part of Letters Patent No. 561,484, dated June 2, 1896.
Application filed January 9, 1896.
T0 (0% whom it may concern:
Be it known that I, [Worms 0. OAnweAN, a citizen of the United States, residing at A11- derson, in the county of Madison and State of Indiana, have invented certain new and useful Improvements in Feeding Devices for Paper-Stock, of which the following is a specification.
My invention relates to improvements in devices for handling and feeding paper-stock; and it is especially adapted for use with ma chines such as illustrated in my Letters Patent No. 509,4:12, though it may be used with any similar device or devices employed for the same purpose.
The object of my invention is to provide a feeding device which shall break up the masses of stock and feed the same in a regular and uniform manner and at the same time permit the separation therefrom of foreign substances of a character that would injure the Washing or disintegrating machinery if fed thereto. I attain this object by the c011- structions shown in the accompanying drawings, in which- Figure 1 is a longitudinal sectional elevation of my feeding device with the elevating Fig. 2 is a transverse sectional view of the feeding devices, which section also passcs longitudinally through the elevating-carrier. Fig. 3 is a transverse sectional view of a portion of the elevating-carrier. Fig. 4; is a detail of the same on a larger scale.
Like parts are represented by similar letters of reference in the several views.
In the said drawings,a represents a longitudinal box or casing, which is preferably rectangular in cross-section. It is provided at the front or receiving end with a pocket a in the bottom thereof, said pocket having an in clined chute or floor a which leads therefrom in the direction in which the stock is moved, as hereinafter more fully set forth. The opposite or discharge end of this casing a is formed with a downwardly-projecting conduit or fiume a which is adapted to fit on and connect with the machine into which the stock is to be fed, so that said flume or conduit will connect with the feeding-opening of said machine. The main portion of the bot- $erial No. 574,841. (No model.)
tom of the casing a, or that portion which lies between the pocket a and the conduit a is formed open, but provided at intervals with slats or cross-bars a which extend from side to side of the casing and are preferably inclined in the direction in which the stock moves.
At the respective ends of the casing and within the same there is journaled a transverse shaft 11 and I), each of which carries a pair of sprocket-wheels 12 12 on which are supportedendless chains b These chains are connected together at intervals by crossbars or slats I), supported by and connected at each end to the respective chains 1) I), the slats or cross-bars being preferably arranged at a distance apart corresponding to the distance between the slats or bars a in the bottom of the casing a.
Below the slatted bottom of the casing a is a chamber 0, preferably formed with an inclined bottom 0, having at its lower end a conduit or pocket 0 with a removable cover 0 Arranged within this chamber 0 is a pipe 0 having a series of slotted openings o in the upper part thereof and connected by a suitable pipe connection 0 to a water supply. At the receiving end of the casing a, and preferably above the shaft Z), is a water-supply pipe 0 which enters the casing at a point above its discharge end and is turned down, as shown, so as to discharge the water admitted through the same downwardly around the end of the carrier formed by the endless chains and their connecting cross-bars or slats.
Extending downwardly at an angle from the receiving end of the casing a, of this feedingcarrier is an elevating carrier, which is adapted to discharge into the feeding-carrier. This elevating-carrier consists of endless chains d 01 passing over suitable sprocketwheels d (1. which are secured to transverse shafts (Z d in a box or casing d. This box or casing d has an inclined bottom (1 the lower end 61 being also preferably inclined, so as to form a pocket or chamber (1 substantially under the lower shaft d, and from this pocket there leads a discharge opening or pocket d having a removable cover, (1. The endless carrying-chains d d are connected together by suitable slats or bars (Z which are armed with projections or spikes (Z any suitable number of which may be employed across the carrier. Below the carrier thus formed there is a false bottom (1,
provided at intervals with slotted openings (Z the rebeing also preferably provided at the lower end of the casing an inclined chute (Z ,havin g slotted openings (1". The sprocketwheels (Z on the shaft d are preferably form ed with extended rims, and to these rims is secured a cylinder (Z of wire netting or gauze, as shown in detail in Figs. 3 and 4E. The ends of the sprocket Wheels d are adapted to rest close to the sides of the easing d and in proximity to discharge-openings d in the sides of said casin g, from which lead conduits (7 to permit the discharge of the waste water, as hereinafter more fully specified. These openings (1 it will be understood, communicate with the inside of the cylinder (1 through the sprocket-wheels, which are formed with arms and openings for this purpose.
The stock to be fed is discharged with a quantity of water into the casing (Z at the lower end, so as to fall between the carrier and the inclined chute d. The carrier is caused to revolve in the direction of the arrow, so that the lower portion of the carrier moves upwardly along the false bottom (Z The water, which is fed with the stock, fills the chamber (Z and causes the stock to float in contact with the cylinder and With the teeth or projections in the elevating-carrier, the surplus water passing through the gauze cylinder out through the discharge-openings (1 The stock which is thus fed into this casing will be broken up by the spikes and drawn downwardly and around the cylinder, thence upwardly along the false bottom, and in the course of its travel will discharge through the slotted openings a large proportion of the foreign substancessuch as sand,lime, and similar materials-which it contains, which sub stances fall into the chamber (1 and can be removed at any time through the opening c1 by means of the removable cover d. The stock is carried by the elevating-carrier and discharged into the receiving end of the easing a, where it comes in contact with the water, which is admitted through the Water-supply c and is carried by the water thus admitted and the feeding-carrier downwardly into the pocket a, and by the action of the water and carrier is more thoroughly broken up, then carried by the cross-bars or slats Z) along the bottom of the casing and over the cross-bars or slats a. Tater is also admitted through the pipe 0 and escapes through the slotted openings 0 into the chamber 0 and keeps this chamber a, as well as the pocket at, filled with water, the surplus water being adapted to overflow into the conduit a As the stockis moved along the bottom of the casing it is rubbed between the respective slats Z) and a and all foreign substances or matter of a greater specific gravity than water will drop into the chamber cbetween the slats a The stock being of a lighter specific gravity will be carried by the feeding-carrier and floated with the water into the conduit a in a uniform and regular manner and deposited into the washing or other machine, which is adapted to receive it.
It should be stated that the cross bars a are supported on longitudinal bars a on each side of the casing at the bottom, the carriercars Z1 being adapted to extend across and be supported at each end on these longitudinal bars, which are preferably shod with metal to form ways or guides for the traveling bars of the carrier. I also preferably employ at the top of the elevating-carrier crossbars 61 having inwardly-projecting spikes (Z which assist in discharging the material from the fingers (Z as the endless chains of the carrier revolve. I
In order to support the upper half of the elevating-carrier, I preferably employ under this part of the carrier belt or chains a slatted false bottom c1 which is located between the respective sprocket-wheels and extends from side to side of the carrier-casing. This arrangement supports the carrier-belt and prevents the same from sagging between the supporting-wheels, and also permits the carrier to run in the opposite direction, if so desired, so that the stock may be carried over-instead of under the carrier-belt. It should be stated also that water is supplied to the carrier-casing through the medium of a supply-pipe (1 which is branched into perforated showerpipes (Z and 61 arranged, preferably, above the cylinder (Z A machine as above constructed is adapted to handle paper-stock in large quantities, to break up the masses of the same and deliver it into the washing or other machine to which it is to be fed in a regular and uniform manner, and freed from foreign substances which would be detrimental to the machine for which these devices are feeders.
IIavin g thus described my invention, I claim- 1. The combination with a longitudinal casing having an open or slatted bottom as described, a traveling carrier having transverse slats adapted to pass over said slatted bottom, a chamber under said casing, and a watersupply in said chamber, substantially as specified.
