JAMES HUXTABLE, OF HORNINGS MILLS, ONTARIO, CANADA.
MlDDLlNGS-PURIFIER.
SPECIFICATION forming part of Letters Patent No. 387,955, dated August 14, 1888.
Application filed September 2, 1886. Serial No. 212,497. (No model.)
To all whom it may concern:
Be it known that I, JAMES HUXTABLE, of the village of Hornings Mills, in the county of Dufi'erin, in the Province of Ontario, Canada, miller, have invented certain new and useful Improvements in Middlings-Purifiers, of which the following is a specification.
The object of the invention is to provide means for reducing the capacity of a middlingspurifier to accommodate it to the quantity of middlings passing through it; and it consists in the peculiar combinations and the novel construction, arrangement, and adaptation of parts, all as more fully hereinafter described and claimed.
Figure 1 is a perspective view of a mid dlingspurifier, partially broken away so as to expose my device. Fig. 2 is a similar view showing my device applied to a machine having a brush traveling at right angles to its length. Fig. 3 is a top plan of a portion of my device, and Fig. 4 is a central vertical section of said portion.
All Inillers are familiar with the fact that the quantity of middlings produced by grinding varies according to the kind and condition of the wheat being ground, and they are also aware of the fact that a mid dlings-purifier will not do as satisfactory work while a smaller quantity of middlings is passing through it than it is designed to purify as it does when the full quantity of middlings it is designed for is being operated upon.
By my device I am able to alter the capacity of the purifier to accommodate it to the quantity of middlings being produced.
In Fig. 1,which I shall first describe, A represents the guides or supporting ways on which the brush B is supported. These guides are designed to hold the brush in contact with the bottom surface of the sieve 0.
With the view of permitting the brush B to drop clear of the sieve,to leave dead-surfaces thereon, I cut a groove or channel, a, at one or more points in the guides A, so that when the brush reaches the said groove or channel a it must necessarily be deflected in its travel and drop clear of the bottom surface of the sieve O, at which point the surface of the sieve not acted upon by the brush will become clogged up, and consequently a dead-surface is formed and the capacity of the machine correspondingly reduced.
With the view of bringing the machine to its full capacity when desired, I provide'at each of the grooves a a pivoted or hinged gate, D,which when set up, as indicated by the gate on the right-hand side of Fig. l, is flush with the top surface of the guide A, so that the brush B when passing over it is still held in contact with the bottom surface of the sieve C.
It will be understood that the brush B in Fig.1 travels in the direction indicated by arrow-that is to say, from one end of the sieve to the other. It is therefore possible to produce the desired result by forming the grooves or channels a in the guides A; but when the brush B extends from one end of the sieve to its other, and is caused to travel across the sieve at right angles to its length, it is necessary to make the brush in sections, as indicated by Fig. 2. The section E in this case is pivoted at one end to the brush and adjustably connected thereto at its other end, as shown, so that the portion of the brush on the section E may be brought in contact with the bottom of the sieve O, or dropped from it, as required.
With the view of cleaning the brush B, I provide a knocker, G, (shown in Fig. 1,) as pivoted between the forks of the arm N, which extends in the same direction as the brush travels and is secured at its inner end to the crossbar O. The upwardly-projectingend of this knocker is slightly above the plane of the head of the brush B, so that the brush in passing .over it will cause the knocker G to rock on its pivot 9, so that when the brush B has traveled around its pulleys H and is return ing to the other end of the machine, as shown in dotted lines, the knocker G comes in contact with its head and jars it sufficiently to produce the desired cleaning result. This will be readily understood from the illustration in Fi l.
l t will be noticed that in a machine constructed as described and provided with a knocker for the purpose of cleaning the brush before its return to the head of the machine it will not be necessary to make what millers call returnings.
While I have described my invention as applied to middlingspurifiers, I do not wish to icO limit myself to that particular class of machines.
Wherever I refer to dead-surfaces I wish to be understood as meaning portions un- 5 touched by the brush, and which are thus allowed to become clogged or imperforate, for a purpose hereinbeforc set forth.
\Vhat I claimas my invention is- 1. The combination of the sieve, the travel- IO ing brushways constructed in relatively-movable sections or parts for holding said brush in contact with said sieve, and means for adjusting portions of said ways, whereby the brush may be allowed to fall out of contact 15 with aportion of said cloth and allow it to become obstructed, substantially as set forth.
2. The combinatiomwith the sieve and traveling brush, of the ways A, provided with grooves a, and hinged gates D, substantially as and for the purpose specified. 20
3. The combination,with the sieve and traveling brush, of the pivoted knoeker G, having its tail end projected above the plane of the head of the brush, substantially as and for the purpose specified. 25 4. The c0mbination,with the sieve and ways A, of the cross-bar O, the forked arm N, secured thereto, the knoeker G, pivoted between the forks of said arm, and the traveling brush, all substantially as shown and described, and 0 for the purpose specified.
