WORKS, INC., OF FULTON, NEW YORK SELF-DUMPING RAG CATCHER FOR HEATING ENGINES Application filed March 29,

This invention relates to self-dumping rag catchers for beating engines which are running on old paper stock. It is not unusual for this sort of stock to contain a high percentage of rags and strings, and it is necessary at frequent intervals to thin up the consistency of the stock, and then lower a rack having open end tines into the channel of the beater allowing the water and thin stock to pass between the tines while collecting the rags and strings upon them. It is customary to raise this rack by cable or winch or by means of a motor driven gear train, and then scrape the rags off on a platform where they are washed off with a hose and the good fibre washes back into the beater. The rags are carted away either to a dump or deposit or to a recovery plant.

The object of this invention is to provide a rag catcher apparatus to accomplish the above stated results and having parts of special construction and arrangement, with the additional function of self-dumping.

The operator may simply stand at the side of the beater and actuate a lever or throw a switch, setting in motion mechanism which raises the rack or catcher and rags to a point some distance above the beater tub, at

which point the entire catcher assembly swings into a substantially inverted position allowing the rags to drop off.

The construction and arrangement of the parts of this invention are illustrated in the accompanying drawings.

Of the drawings Fig. 1 represents a side view of all the parts assembled, and Fig. 2 is a vertical section of the tub with a front View of this invention applied thereto.

Throughout the drawings and description the same number is used to refer to the same part.

Considering the drawings, a tub 1 has thereon a screen platform 2, and rising from the tub are tracks 3 and 4 consisting of channel irons having near the top a bend 5 whereby the track extends above the tub in two different directions with respect to the tub. The upper ends of the track members are secured to the floor 6 of the building, to which are also 1933. Serial No. 139,983.

attached short beams 7 for the supportof the pulley mechanism hereinbelow explained.

Rollers 8 engage the tracks and carry the catcher 9 which comprises the spaced bars provided with inclined ends of customary formation. A cord 10 from the catcher is led to a drum 11 on the horizontal shaft 12 supported in bearin s secured to the beams 7. On shaft 12 is a loose pulley 13 driven by a friction wheel or roller 14 on a parallel shaft 15 driven by a pulley 16 on the shaft deriving power from the belt 17 leading to any source of motor force not shown. To connect the pulley 13 and shaft 12, a friction clutch 18 is introduced arranged to be operated by the rod 19 upon moving lever 20.

It will be understood that this invention is in no sense limited to the driving mechaism illustrated, as this may be clearly modified or replaced by other well known devices.

In operation the catcher is raised by the cord and as the rollers travel the track the catcher reaches the position shown in broken lines and is substantially inverted, dumping any rags, strings and the like upon the platform 2. By suitably working the lever 20, a shaking movement may be given the raised catcher to loosen its load.

Having now described this invention, I claim 1. In a rag catcher, in combination with a tub, a screen mounted on the tub, a track extending above the tub in two different directions with respect to the tub, a rag catcher constructed to travel the track, and means for raising the catcher and for controlling its movements whereby the catcher may be inverted and dumped above the screen.

2'. In a rag catcher, in combination with a tub, a track extending above the tub in different directions with respect to the tub, a rag catcher constructed to travel the track, and means for raising the said catcher and for controlling the movements thereof whereby the catcher may be dumped above the tub.

3. In a catcher, in combination with a tub, a track extending above the tub in different directions angularly with respect to the tub, a screen supported by the tub, a catcher provided with spaced bars having inclined end portions and constructed to travel the track, and means for raising the said catcher and for controlling the movements thereof whereby the catcher may be inverted 5 and dumped above the said screen.

4 In a rag catcher, in combination with a tub, a track extending above the tub in two different directions angularly with respect to the tub a catcher provided with spaced 10 bars having inclined end portions and constructed to travel the track, and means for raising said catcher and for controlling the movements thereof whereby said catcher may be inverted and dumped above the tub.

1 In testimony whereof I afliX my signature.

GEORGE D. STEVENS.
