UNTTED STATES ABEL P. HOLUOMB AND AUGUST HEINE, OF SILVER GREEK, NEW YORK.
PATENT OFFTQE.
CENTRIFUGAL FLOUR-BOLT.
SPECIFICATION forming part of Letters Patent No. 267,529, dated November 14, 1882.
Application filed September 7, 1882. (No model.)
To all whom it may concern Be it known that we, ABEL P. HoLcoMB and AUGUST HEINE, of Silver Creek, in the county of Chautauqua and State of New York, have invented anew and useful Improvement in Centrifugal Flour-Bolts, of which the following is a specification. v
This invention relates to certain improvements in that class of bolting-machines known as centrifugal bolts, which are provided with a rotating cylinder and heaters rotating within the cylinder, whereby the material to be bolted is driven against all parts ofthe cylindrical bolting-surface.
The object of our invention is to improve the operation of this class of machines by freeing the rotating bolting-cylinder from the material which tends to adhere thereto, without at any time materially obstructing any portion of the cylindrical bolting-surface; and our invention consists, to that end, in combining with a rotating bolting-cylinder a rotating spiral brush which runs in contact with the outer side of said cylinder, as will be here inafter fully described.
In the accompanying drawings, Figure l is alongitudinal sectional elevation of our'improved flour-bolt. Fig. 2 is an elevation of the front end of the machine. Fig. 3 is an elevation of the rear end of the machine. Fig. 4 is a view of the gear mechanism for driving the brush of the bolting cylinder.
Like letters of reference refer to like parts in the several figures.
A represents the frame of the machine, and A the iuclosing casing, which is made airtight, as nearly as practicable.
B represents the bolting-cylinder, which is composed of two heads, D D, connected by stay-bolts, rods, or bars (I, and which is covered with bolting-cloth b, of suitable mesh, supported by suitable rings, (1. The head D of the feed end of the bolting-cylinder is provided with a hollow journal, e, which turns in a bearing, 6, secured to the frame A, and the head D at the tail end of the bolting-cylinder is provided with a similar hollowjournal, 0 which turns in a bearing, 0
frepresents the rotating heaters, which are arranged in the bolting-cylinder and secured to ringsf. The latter are attached by arms f to a shaft, f which passes through the hollow journals 0 c and is supported in bearings f f The cylinder B is slightly inclined from .the head D toward the head D to cause the material to pass slowly through the cylinder or the beatersfmay be arranged spirally to propel the material through the cylinder in the proper direction; or both means may be employed together to impart the necessary movement to the material.
0 represents a spiral brush, arranged in the casing A so as to run in contact with the bolting-cylinder B and remove the material which may adhere to the same. This brush reaches all parts of the outer surface of the rotating bolting cylinder and cleans the cloth thoroughly, and at the same time leaves the cloth substantially unobstructed, as the spaces between the threads or turns of the brush are ample to permit the free escape of the flour.
PP represent two screw-conveyors,arranged below the bolting-cylinder B, one above the other, and provided in their troughs with a suitable number of openings controlled by slides 19, so that the bolted material can be drawn off at any desired point.
q represents the driving-pulley, secured to the end of the shaftf and q is an endless belt which runs around a small pulley, g on the shaft f and a larger pulley, g on the shaft of the lower couveyer, P, whereby the latter is rotated.
i" represents an endless belt, which runs around a small pulley, r, on the shaft of the lower conveyer, P, anda larger pulley, 1 ,011 the hollow journal 6 wherebythe cylinderB is rotated from the conveyer P 'with much less speed than the heaters.
The upper conveyer, P, is driven from the lower conveyor, P, by gear-wheels s s, and the spiral brush 0 is driven from the upper conveyer, P, by gear-wheels t 13 t The gearwheels t t are secured respectively to the shafts of the conveyer P and of the'brush, and the gear-wheel t is an idler turning on an arbor secured to an adjustable arm, t The bearings t of the brush-shaft are made adj ustable toward and from the cylinder B to enable the brush to be adjusted as it wears off, and the adjustable idler t is provided to maintain the connection between the wheels t 15 under these adjustments of the brush.
We do not in this application desire to cover any improvements herein shown, except those which are specifically pointed out in the claim, and reserve the right to cover such other improvements by separate applications for patent.
\Ve claim as our invention The combination, with a rotating bolting- 1 cylinder, of arotating spiral brush running in contact with the outer side of said cylinder, whereby all parts of the cylinder are freed from the material adhering thereto, without 15 at any time materially obstructing any portion of the cylinder, substantially as set forth.
