SPECIFICATION forming part of Letters Patent No. 298,387, dated May 13, 1884.
Application filed July 16, 1883.
To all whom it may concern.-
Be it known that 1, WILLIAM M. 'JEWELL, a citizen of the United States, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Automatic Shelf-Feeders for Middlings-Puritiers and Roller-Mills, of which the following is a full, clear, and exact description.
This invention is in the nature of improvements on the feed mechanism for roller-mills for which Letters Patent No. 280,184 were granted to me the 26th day of June, 1883.
The object of the invention is to provide a shelf-feeder for middlings-purifiers, roller and other flouring mills or machinery, wherein a steady and even feed of the material to be acted upon is required, the device herein described being operated either automatically by the weight of a given load or mechanically held and released at given intervals, as will presently appear. 7
The invention consists in the combinations of parts, as hereinafter specified and claimed.
In the accompanying drawings, in the several figures of which like parts are similarly designated, Figure 1 is a vertical section of the feed mechanism as adapted to a middlingspurifier. Fig. 2 is a horizontal section on a line just above the level of the shelf, and Fig. 3 is a vertical section of my improved feed mechanism adapted for roller-mills.
The letter a may designate the top boards of amiddlings-purifier, andb ahopper or chute suitably arranged therein, with a feed-spout, 0, leading into said hopper. The hopper will be arranged in accordance with the requirements of the machine to which it is applied.
01 d are horizontal bars attached to the walls of the purifier at the point of entrance of the feed mechanism. From the ends of these bars depend spring-straps e e, to the lower ends of which are fastened horizontal bars f, and these bars support the shaking-frame B, purposely so designated, to indicate its correspondence in essentials to the shaking-frame of my pet ent referred to. The discharge end of the hopper projects into the shaking-frame, substantially as shown, and is covered or closed by a pivoted or hinged shelf, 9." This shelf is hinged or pivoted to arms h h at 2, and said (No model.)
The shelf is provided with means for holding it normally up against and closing the discharge end of the hopper, and I have shown such means as. an arm, m, provided with a movable counterpoise, 02, held to its adjustment on said arm by a set-screw, o, the motion of said shelf being controlled by the .engagement of a stop-hook, p, with the arm m. This stop-hook has a slot, q, and is arranged in a bar, r, wherein it is movable, a set-screw, s, passing into the bar through the slotted hook, to clamp the hook in any given position. The arm at is fast to the shelf 9 and moves with it, its weight being adjusted to permit the shelf to automatically drop when the required quantity of material to be fed has accumulated upon the shelf. Thus this quantity, or the feed, may be regulated with great nicety. Instead of having the feed automatic, the hook 1) may be used to hold the shelf a given length of time-say for repairs or in running-and be disengaged manually or mechanically to permit the shelf to fall; but in this case each machine will require the almost constant care of an attendant.
The shaker B mayhave one or more shelves, t, corresponding, if desired,.in construction and function with the shelves b c d of the patent referred to, or of other approved form. The discharge end of the shaker Bis open, the bar 0' simply extending across it at that end at a suitable non-interfering distance. The desired shaking motion is imparted to the shaker B in a middlings-purifier by connections a with its shaking-screen o, for example, al-
though I do not necessarily limit my invention to such specified connection for getting a shaking or vibratory movement.
In the form of feed mechanism shown in Fig. 3, b is the hopper; B, the shaker; O. the casing inclosing the same, and D D a pair of grain-grinding rolls arranged in any of the approved forms. E is a spout arranged to deliver the grain to the rolls over distributingshelv'es F F, projecting at an incline from op posite sides of said spout. t t tare shelves or boards projecting at inclines from opposite sides of the shaker B, and corresponding in construction and function with the shelves 012 and board (I of my former machine referred to, and similarly equipped, if desired. J is a shaft suitably borne by the framing, and driven, as bya belt, from, say, the shaft of the fast roll of the pair of rolls D D. This shaft may have a crank or an eccentric, with which the rod or pitman K is connected, and said pitman then connected with the shaker, to impart to it a shaking or vibratory motion.
A spring, h, (shown in dotted lines, Fig. 1, and full lines, Fig. 3,) may be substituted for the weight, and the resistance of such spring is governed by the adjustment of the hook p, with which it engages.
The lowermost shelf 6 of the shaker-frame may be made adjustable at its lower end in several ways to insure uniform distribution of the material to be treated when the relative levels of any of the parts are disturbed. As
one illustration of means for effecting this, I have shown in Fig. 3 said shelf 15 provided with a slotted segment, f, held to the side of the shaker by a thumb-nut and bolt, f. As'
the shelf is thin, by using its hinges as fulcra its discharge end can be sprung and held by the segment and thumb-nut in any desired position to adapt the feed to the position of the rollers or purifier. The segment and thumbnut shown on the middle shelft is to vary the inclination of said shelf, which is pivoted near its center, as in my patent referred to.
The operation of the machine is as follows: The material to be acted upon is fed-may be continuously-into the hopper, and the capacity of the treating mechanism for the particular material being fed first known, the shelf r is set by its weight or spring to discharge that known quantity whenever it shall have been fed upon it. The operation of the shelf is thus in either instance automatic.
Vhenever, as by breakage, it is necessary to stop the machine, the stop-hook 1) may be adjusted to hold the arm in. till repairs can be made.
Inasmuch as the hopper-closing shelf g is borne by the shaker B, said shelf has a motion across the discharge end of the hopper; hence it must follow that the agitation incident thereto will put the material being fed in motion, and thus serve to insure its descent, preventing clogging of the hopper and a fitful supply to the treating mechanism.
\Vhat I claim is- 1. The combination, substantially as shown and described, of a stationary hopper, a frame provided with distributingshelves beneath it, means to shake or vibrate such frame, and a shelf pivoted in said frame at the discharge end of said hopper, and provided with a counterhalancing device, to render it automatic, and a hook to engage said shelf to limit its range of movement, as and for the purpose set forth.
2. The combination, substantially as shown and described, of the stationary hopper, the shaker suspended beneath it, the shelf for 010s ing the discharge end of said hopper, pivoted in said shaker and moving with it, means, as set forth,for vibrating said shaker, the adjustable counterbalancing mechanism connected with said shelf to vary its resistance, and means, substantially as specified, for limiting the fall of the shelf and for positively preventing its fall, as and for the purpose described.
3. In a middlings-purifier orroller-mill, the combination, substantially as shown and described, with the hopper and its discharging shelf, of the shaking-frame and its bottom or delivery shelf, having adj usting mechanism, as set forth, to insure a uniform distribution of the material fed relatively to the level of the purifier or roller-mill, as set forth.
In testimony whereof I have hereunto set my hand this 9th day of July, A. D. 1883.
WILLIAM M. JEWELL.
