UNITED STATES PATENT OFFICE.
HALE E. HAIVK, OF BUOYRUS, OHIO.
GRAIN-METER.
SPECIFICATION forming part of Letters Patent No. 461,336, dated October 13, 1891. Application filed October 1,1890. Serial No. 366,744. (N model.)
To all whom it may concern.-
Be it known that I, HALE E. HAWK, a citizen of the United States, residing at Bucyrus, in the county of Crawford and State of Ohio, haveinvented a new and useful Grain-Scale, of which the following is a specification.
This invention has relation to scales for measuring grain and other cereals or materials, and the objects in view are to provide a machine adapted to correctly and rapidly weigh grain in predetermined quantities, and
to be so constructed as to deliver all particles of grain previous to the return of the weighingreceptacle for the purpose of receiving a fresh supply, and, furthermore, to accomplish the above by the weight of the grain and withoutsacrificing the simplicity and cheapness of the machine as a whole.
Various other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be particularly pointed out in the claims.
Referring to the drawings, Figure l is a side elevation of the grain-scale constructed in accordance with my invention. Fig. 2 is a Vertical longitudinal section of the same. Fig. 3 is an opposite side elevation. Fig. I is a transverse vertical section in front of the hopper. Fig. 5 is a similar view through the hopper. Fig.6 is a plan view of the machine. Fig. 7 is a sectional view similar to Fig. 2, but
showingthe parts in their proper position when dumping.
Like numerals indicate like parts in all figures of the drawings.
In practicing my invention I construct the frame-work of the usual opposite side frames 1, connected atintervals by suitable tie-bolts 2, and mount the same upon a suitable base.
3 designates a bifurcated yoke which terminates at its front in a f0rwardly-disposed scale-beam 4., upon which is mounted asleeve 5, made adjustable by a set-bolt (l, and in the sleeve is mounted for adjustment a poised bar 7, designed to receive a series of weights 8. From the opposite branches of the yoke or bail there depends fulcrumed arms 9, which terminate in bearings 10, mounted in bearing-brackets 11, secured to the inner faces of opposite side bars of the frames.
12 designates a feed-spout located vertically opposite and depending into the receptacle hereinafter mentioned, and to the same is pivoted the semi-cylindrical-shaped cutoff l3.
l4 designates a pair of brackets located upon the front bar of the frame-work, and in side brackets there is journaled a rock-shaft, which rock-shaft between the brackets is provided with a central cranked portion 15, and outside of the brackets with cranked arms 16, disposed at substantially a right angle to the central cranked portion. The outer cranked portions are connected to the cut-off of the feed-spout by means of a pair of connectingrods 17, which rods are formed in sections 18 and 19, the formerbeing slotted, as at 20, and connected to the latter by means of set-bolts 21, whereby said rods are made adjustable. Upon the central cranked portion of the rock shaft just mentioned is designed to rest the front end of the scale-beam, over which end is adjustably mounted a saddle 22 by means of a set-bolt 23. The lower end of the saddle is V-shaped and is provided with opposite bearings 24, (see dotted lines, Fig. 7,) in which are journaled opposite pairs of rollers 25, over which rides the central cranked portion of the aforesaid rock-shaft.
In opposite pairs of side bars there is journaled a brake-shaft 26, which at its center is provided with a ratchet-wheel 27, fixedly mounted thereupon. An arm 28 is loosely mounted upon the shaft at one side of the ratchet-wheel and carries a loose gravitypawl 29, the free end of which is designed to engage the teeth of the ratchet-wheel. The arm just mentioned is bell-crank in shape, and to the opposite end of the same, as at 30, is pivoted a vertical rod 31, the upper end of which is bifurcated and loosely embraces the scale-beam, above which the terminals of the bifurcations are connected by loose roller 32. Below the bifurcations the side bar is connected to the rock-shaft by means of the rock-arm 3%, as shown, whereby said bar is steadied in its movements.
Near one end of the brake-shaft there is mounted a brake-pulley 35, around which is passed a brake-strap 36, one end of which is fastened to the depending U-shaped bracket 37 and the opposite end to the inner end of the weighted end of a lever 38, pivoted in the opposite branch of said bracket and carrying the weight 39 adjustably thereupon.
40 designates the main receptacle or hopper, which, by straps 4:1, is loosely suspended on the rear terminals or ends of the yoke or bail of the scale-beam. In opposite straps 42, secured to the opposite sides of the receptacle, there is pivoted a hinged cut-off or gate 43, adapted to close the mouth or lower end of said receptacle. Above said gate or cutoff there is pivoted, as at at, opposite weighted levers 45, their outer ends carrying weights 46 and their inner ends pivotally connected to connecting-rods 47, the lower ends of which are pivotally connected to the opposite ends of the cut-off or gate. Between its weight and fulcrum-pointthe opposite levers are provided with depending L-shaped stops 48, designed to come in contact with opposite side bars 49 when said receptacle is being lowered, and the said levers are raised at their weighted ends and the free ends of the gate depressed or lowered, so as to uncover the opening or discharge in the lower end of the receptacle.
5O designates the receiving-hopper designed to discharge the grain into any receptacle placed thereunder, and said hopper is provided near its lower end with the hinged gate 51, adapted to be raised and lowered to uncover the opening in the hopper. The free end of the gate is pivotally connected to the lower end of a vertical connecting-bar 52,the upper end of which is inwardlybent, as at 53, and designed to take over and engage a projection 54, formed upon one side of the receptacle. Below its end the connecting-bar is provided with a pair of straps 55 and 56, the inner or former strap passing through a guide or eye 57, while the outer or latter strap is pivotally connected, as at 58, to the free end of the lever 59, fulcrumed, as at 60, upon one of the side frames, which lever at its opposite end carries a weight 6]..
The above being the construction, the operation of my scale is as follows: The beam being lowered to its normal position and the weight adjusted, the valve or cut-oil of the spout is opened to permit grain or other materials to be weighed to pass therefrom into the receptacle, the bottom of which is closed by the gate heretofore described. As the weight of the grain or other material approximates that of the weights, the receptacle begins to lower slightly, the cranked rock-shaft at the front end of the frame-work is freed or relieved of the weight of the scale-beam heretofore resting thereupon. The weight of the grain in the cut-off, which, it will be observed, is so constructed as to permit the grain to overflow therefrom into the receptacle, causes said cut-off to swing to nearly a closed position. As the cut-off swings toward its closed position, it balances with the beam, and the central cranked portion of the rock-shaft, just mentioned, rides over the inner roller of the saddle and takes into the V-shaped recess formed upon the under side of the saddle between the rollers, and said cranked portion is thereby held in such position that but a few grains at a time can escape from. the cut-off or overflow therefrom into the receptacle. \Vhen sufficient grain has thus passed into the receptacle and wholly counterbalances the weights upon the scale-beam, it depresses the receptacle and elevates the scalebeam to such a degree as to wholly liberate the crankshaft and permit the cut-off of the feed-spout to entirely close. It willnow be seen that the receptacle has received exactly the amount of grain desired, as determined by the weights upon the beam. As the receptacle descends, the depending stop upon the weighted lever, which controls the movement of the gate of the receptacle, comes in contact with one of the side bars of the opposite side frames, and the weighted end of the said lever is thus elevated against the influence of the weight. Consequently the free end of the gate is positively lowered or depressed, so that the mouth or discharge end of the receptacle is opened and the grain can escape therefrom. As the grain passes from the receptacle, it falls upon the gate pivoted within the discharge-hopper and depresses said gate, causing the weighted lever connected to the same, and which normally raises the gate, to be elevated against the influence of its weight. The downward movement of the gate also draws down the connecting-rod which connects the gate with the aforementioned weighted lever, and in so doing the upper bent end of the lever is drawn down upon the projection located upon the side of the receptacle. In this way the receptacle is prevented from returning to a raised position and thus closing the gate and arresting the discharge of grain until every grain has passed from the gate of the lower hopper, by which time it will be apparent that all grain has passed from the receptacle. The weight upon the scale-beam now returns the receptacle to an elevated position and the several gates before mentioned resume their normal position. By reason of the weighted arm connected to the connecting-rod the bent end of the connecting-rod is by said arm elevated above the projection upon the receptacle, so thatits weight does not in any way atfect the perfect balancing of the scale-beam, the receptacle, and the weights.
When the beam is in the act of descending, the gravity-pawl being in mesh with the ratchet upon the brakeshaft, said brake-shaft is rotated slowly or gradually by reason of the brake band or strap being snugly drawn upon the brake-pulley by the weight upon the brake-lever.
The connecting-rod 56, it will be observed, has its upper end forwardly curved, so that its bent extremity engaging with the receptacle traverses a line across the pivot of the valve and the connection to the valve, thus gaining on the leverage, so that it does not lop and yet arrives ata normal position easily after the pressure of grain has left.
In practice I have found that owing to foreign mattersuch as straws, &c. being in the grain the cut-off 13 will refuse to automatically entirely close, and thus a small stream of grain continues to overflow the edge of the cut-off after the receptacle has been lowered. Oftentinies, also, dishonest persons tampering with the grain-scale maydepress the crankshaft 15, and thus continue the escape of grain into the receptacle after the same has lowered and received its proper quantity of grain. By inyinvention I avoid such contingencies above set forth, which part of my invention I will now proceed to describe.
63 designates a bar or rod compoundly curved,the lower end of the bar being mounted upon the bolt 30 and the upper end extending under the central crank 15 of the crankshaft 14. Below its upper end the curved bar 63 is connected to the frame-work by a link 64,said link being pivoted to the frame-work. As the grain in the receptacle serves to lower the same and elevates the front end of the scale-beam, said scale-beam, as before stated, elevates the rod 31, and it will be observed it will also elevate the curved bar 63. Then the scale-beam leaves the cranks 15, said crank is elevated by the closing of the cut-off. At the time that the crank is elevated the bar (33 is raised, so that its upper end swings up under and against the crank 15 and holds the same in that position, so that it is impossible for a person to tamper with the cut-off by lowering the crank or for the cut-oif to be otherwise than perfectly closed when the receptacle is lowered.
Although shown and described herein, I do not in this application broadly claim the following: The crank-shaft and device connecting the same with the cut-off, the rotary brake mechanism and connections between the same and scale-beam, and the weighted and pivoted .gate at the lower end of the receptacle, as such forms the subject-matter of separate pending applications bearing Serial Nos. 351,177 and 377,702.
