IMPROVEMENT IN GRINDING-MELS.

TO ALL WHOM IT MAY CONCERN: A
Be it known that wo, MreHAsL W. Hemos and JAMiis H. Rsnriunn, of Bloomington, in the county of Monroe, and State of Indiana, have invented a new and improved Automatic Grist Alarm and we do hereby declare that the following is a full, clear, and exact description thereof:
The object of this invention is to provide means by which the miller in custom grist-mills may he notified at what time the bags should be changed from one griet to another, so that each customer may get the i'lour or meal from his own grain and the invention consistsin so arranging a perpetual screw or worm on a horizontal shaft, which shall work in a wbrm-wheel on a vertical shaft, and hy which' the vertical shaft shall be revolved, and with a screw-thread on the upper portion of the vertical shaft, that it will operate on springs in such a manner that a bell will be struck at any given or desired time, thus giving the required notice to the miller.
And to enable others skilled in the art to make and use our invention, we will proceed to describe its construction and operation, reference being had to thc accompanying drawings, which forma part of this specification, and to the letters of reference marked thereon.
Figurel represents a side elevation; and
Figure 2, a plan `or top view.
Similar letters of reference indicate like parts.
A represents the bed-plate or platform to which the apparatus is attached. B Bare vertical pieces attached to the bed A which support the springs. ,C is an arch connecting the pieces B B, and also supporting the top of the vertical shaft. D is the vertical shaft, it being stepped into the bed-plate at the bottom end, and with a journal or pivot on the top, andlis supported by the arch C. This shafthas adeep screw-thread cut on its upper portion and a worm pinion near its lower end; this pinion is indicated in the drawing by a, and the thread on its upper portion by the letter f. G is a horizontalshaft driven by the power that drives the mill by a belt on the pulley- F. This shaft revolves on journals' or bearings which are secured tothe bed-plate. On one `end of this shaft the worm is made fast,'and it is so placed that its thread works in the worm-wheel on the vertical shaft, and causes the vertical shaft to revolve. Fast to the outer ends of the -two pieces of blocks, B B, two springs are attached, one spring on each; they are indicated by I and `J in the drawing. The spring I has an' up and down motion, the spring J a lateral motion. I has a knife-.edge upon the side next the vertical shaft, whichedge enters between the screw-threads on the shaft, and the spring I is carried up as theishaft revolves, the tension of the spring being increased as it ascends. This spring is held in position and pressed against the screw by the other spring J.' As before stated, this spring J has a lateral motion which is for they purpose of keepin-g the other spring in place the desired length of time. The end of J is turned up and stands at about right angles with the other spring. The length of this turned-up portion of J determines the length of time which the machine shall run before the alarm is given, for when the screw carries the end of the spring I-ahove the end of the turned-up portion of J, it immediately flies out of the thread (being no longer pressed upon by J) and springs down on the other side of-J to its natural position, and strikes the bell. The turned-up e'nd of 'J is sharp and stands inclined toward the shaft, the sharp end striking the screw under I, and the inclined sur-I face of the screw-thread, as well as ofJ, allows I to make the movement described, it having a little spring laterally for that purpose. The bell K is conveniently placed a little below the natural position of I, but when I is released and flies down, the tension of the spring throws the extreme end far enough below its natural position to hit the'bell and give therequired alarm. The period or time for the alarm would, of course, be
governed bythe speed of the horizontal shaft G, and the speed of the shaft G will be governed by a set of section cone-pulleys and belt, so that every section or change of speed shall stand for a given' quantity of grain to be ground before the alarm is given. Or the spring I may be set in the screw by an index graduated to different quantities of grain. I
IIaving thus described our invention, what we claim as new, and desire to secure by Letters Patent, is The horizontal and vertical shafts G and D, with the worm and worm-wheel E and d, the springs I and J and the bell K, when arranged and combined substantially as herein described end for the purposes set forth.
