UNITED STATES PATENT OFFICE.
JUDSON A. DE mm on NEW YORK, N. Y., ASSIGNOR T0 PROCESS ENGINEERS, INCOR- PORATED, OF NEW YORK, N. Y.
ATTACHMENT TO BEATING-ENGIIQ'ES.
Specification of Letters Patent.
Patented May 10, 1921 To all whom it may concern:
Be it known that JUDsoN A. DE CEW, a subject of the King of Great Britain, and native of the Dominion of Canada, residing at New York city, New York, has invented a new and useful Improvement in Attachments to Beating-Engines, of which the following is a specification.
This invention relates to attachments to beating engines and the object thereof is to greatly increase the efliciency of beating engines already in use by the application thereto of relatively simple attachments, and with this object in view, the invention consists essentially in deflecting plates, having a concave face next to the beating roll of the engine, and located on each side of the roll.
The invention is illustrated in the accompanying drawing in which Figure 1 shows a plan view of a beating engine with the attachments of the invention in place.
Fig. 2 shows a partial vertical section taken along the lines 22 in Fig. 1.
Fig. 3 is a view similar to Fig. 2 except that it is an enlarged view of the roll and its attachments.
Fig. 4 is a plan View of a detail.
In the drawings, the numeral 11 represents the vat of the beating engine, 12 the mid-feather, 13 the beating roll,'1l the knives on the roll, 15 the guard over the roll, and 16 the backfall. 17 indicates stock in the beater and 17 the stationary blades under the roll. So much is of ordinary construction and it is to devices of the character just described that my invention will be applied.
In advance of the beater, I propose to locate a deflecting element 18, substantially crescent-shaped in cross-section, with its concave face adjacent the beating roll 13. This deflector extends entirely across the face of the beating drum (or beater) and is adjustably supported at one end to the side wall 19 of the vat and at the other end to the side of the midfeather 12. It must be adjustably supported to allow for the usual vertical adjustment of the roll. One method to so support the deflector is to provide lugs or bosses 20 which may be squared, to the ends of the deflector and to have them coact with grooveways 21 provided on the side and midfeather of the vat respectively. As these grooveways would be open at the top, the deflectorcould be easily removed therefrom. 22 indicates one or more stops to positively prevent pivotal movement of the deflector sufliciently to have its upper edge engage the knives of the roll.
23 indicates a further deflector extending all the way across the rear of the roll and also having a concave face adjacent to the roll. 24 and 25 indicate angular faces of the deflector which in this case are preferred to the crescent. shape of the front deflector. This deflector is adjustably supported similar to the front deflector and the description of the supporting elements 20', 21 and 22 are identical with 20, 21 and 22.
26 represents a secondary doctor for the roll and the lower edge 27 of the rear deflector a primary doctor. It is preferable that the front deflector 18 lie almost wholly below the level of the stock 17 in the vat.
In beating engines at present in use, it is desired to have the stock pass under the roll so that the purpose of the revolving roll is to carry the stock longitudinally along the bottom of the vat past the stationary knives under the roll but I find that the knives of the roll in descending engage the upper portion of the stock and give it a downward movement as only the knives near the bottom of the vat give it the desired horizontal movement. This downward or vertical movement given some of the stock causes' eddies and otherwise seriously interferes with the stock flowing horizontally besides requiring an unnecessary amount of power to rotate the roll. In other words, all force used by the blades in imparting vertical the curvature of the roll, it prevents the stock from coming into contact with the blades of the roll until they have reached such an angle in relation to the stock that they will act upon it only longitudinally of the Vat.
The rear deflector acts as a doctor at 27 and otherwise assists in keeping the stock away from the blades of the roll after it has once passed thereunder. The secondary doctor 26 will strip from the roll any stock that escaped by the primary doctor 27 and it will fall back along the angular face 24 of the deflector.
What I claim is: 1. In a beating engine, in combination, a vat, a roll, guideways within the vat having their lower ends closed, and a deflector ends thereof, said deflector having a concave face adjacent said roll.
4. In a beating engine, in combination, a
vat, a roll, and a deflector pivotally supported within said vat.
5. In a beating engine, in combination, a vat, a roll, a deflector pivotally supported within said vat, and means independent of the supporting means for limiting the movement of said deflector.
In testimony whereof, I, the said JUDSON A. DE CEW have signed my name to this specification in the presence of a subscribing witness, this 16th day of April 1919.
JUDSON A. DE CEW. Witness: MARSHALL CLARK.
