B. F. HARRINGTON AND U. B. BURRIS, OF MISSOURI CITY, MISSOURI.
COOLING AND FEEDING MATERIAL TO MILLS.
Specification of Letters Patent No. 23,682, dated April 19', 1859.
for the purpose of conveying air and grain between the stones of a grinding mill as will be set forth.
Figure'l is a top perspective of our arrangement. Fig. 2 is a side elevation showing a section of one of the mill stones. Fig. 3 is a perspective view of the inner tube with the spiral buckets surrounding it.
In the drawings A represents a large tube which is made to fit in the running stone of the mill. In this case it is shown in the upper stone. WVithin this tube is a much smaller tube marked B, through which the rattle staff passes. Between these two tubes a series of spiral buckets D, D, D, are placed, which extend from their top to their bottom. These buckets open at their top into a hopper H, for the purpose of securing the grain. Around the top of the hopper H, is placed a collar, C, and around the top of the tube A is placed a collar, (4. Between these two collars, are three spiral chambers, E, E, E, with wide mouths, and which diminish as they extend around. These chambers open at their rear end into the buckets D, D, D. The object of these chambers is to catch the air as they revolve with the stone, force it into the buckets D, D, D, and thence down in bet-ween the stones. The grain is carried after being dropped into the hopper H down between the stones through the spiral buckets, not only by the spiral form of the buckets, and its own gravity, but by means of the currents of air which are forced into the buckets by means of the air chambers, E.
There has always been a diificulty in milling heretofore in carrying the grain down between the stones when the stones were driven at a very high speed. The centrifugal action consequent upon an accelerated or very high motion causes very often, the grain to stick or cling to the eye of the stone. After one grain clings to the stone another will lodge, and then another, until quite a number collect. They will then from some cause or other all at once fall, and thus clog the stones. This method of feeding entirely precludes the possibility of this and it matters not how high the speed may be, it will feed uniformly and in proportion to the speed, The principal advantage gained from this arrangement is-the forcing of the air down in between the stones for the purpose of keeping them cool, and thus keeping the ground material cool. Whenever the stones begin to heat, the material begins to heat, and when the stones become hot, the material is burned and thus destroyed. We
are thus enabled to run the stone at any de-- sired speed, and any length of time, without fear of heating, and without fear of burning the grain. We dispense with the old elevators and are enabled to empty the material immediately into the bolting apparatus, thus making a feeder, a cooler, and at the same time an economical apparatus, dispensing with the expensive arrangement of elevators.
Having thus fully described our improvement what we claim as new and desire to secure by Letters Patent is 1. The spiral chambers, E, E, for the purpose of creating currents of air for keeping the stones cool substantially in the manner described.
2. The combination of the spiral buckets, with the spiral chambers, when both are constructed and arranged in the manner and for the purpose herein fully set forth.
