DEXTER D. HARDY, on DELAVAN, ILLINOIS, ass'ronon or one-HALF or HIS RIGHT TO QUINTUS ORENDORFF.
IMPROVEMENT IN MAGNETIC GRAlN-SE PARATORS.
Specification forming part of Letters Patent No. 222,627, dated December 16, 1879 application filed I July 25, 1879.
To all whom it may concern Be it known that I, DEXTER D. HARDY, of
Delavan, in the county of Tazewell, in the State ofIllinois, have invented an Improvement in Magnetic Devices for Extracting Fragments of Metal from Grain; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed drawings, making a part of this specification, in which like letters of reference refer to like parts, and in which- Figure 1 represents a perspective view; Fig.
2, a plan view; Fig. 3, a vertical cross-section on line a a a a, Fig. 1.
This invention consists of a magnet or series of magnets made and arranged in a graintrough, in the manner as hereinafter described, in combination with a shield or shields of a slightly magnetic or non-magnetic character, lnterposedbetween the magnet and armature,
for the purpose of placing the armature as near the magnet as is necessary to accom-.
plish the purpose of preventing the impairment of the strength of the magnet as much as possible consistent with sufficient attraction of said magnet upon metal fragments usually present in uncleaned grain to gather them np; also, in the combination of transverse parallel bars and clamping-bolts for securing the magnets in position in the trough, as will be hereinafter more fully explained.
B represents the armatures, (used to preserve the powerof the magnets,) which are each faced on that side next to the magnets above them with a thin strip or facing of copper or other substance sufiicient to separate the magnet F from the armature, and at the same time to conserve the strength of the former as much as possible consistent with sufficient attracnets between them,by means of bolts 0 e, the
magnets in such a position that they are equidistant from each other, the distance being the same, or nearly so, as thatbetween the arms of the respective magnets. I make said magnets of inch by one-fourth inch bar-steel,
(preferably,) sixteen inches inlength, bent so warns PATENT OFFICE.
as to form parallel arms about one inch apart,
the same distance as that between each magnet of a row.
The rows of magnets are .so arranged that their arms (poles) are opposite to the spaces between the arms of opposite rows of magnets, so as to break the better the current of grain up into continually smaller currents. It will thus be seen that one of these magnets, so constructed and arranged, breaks the graincurrent in two parallel lines, so that two rows of three magnets each break said current in twelve placesa great advantage over an equal number of the ordinary horseshoe, or U mag net, in which the widest part of its substance is in the plane of its flexure, thereby economizing the number of magnets, (a. 0., my SlX magnets accomplish as much work by this arrangement as twelve magnets with their respective poles arranged in one line, as in the U-magnets.)
By my plan one-fourth of the magnets may be removed to clean them, while three-fourths of thewhole number are in place, whereas in the U system of magnets it would be necessary to remove one-half of their number, leaving as many as one-half in service.
What I claim as my invention is- 1. The transverse parallel bars E, arranged to secure the magnets in a line or row across the bottom or base of the trough of a grain spout or conveyer by means of theclampingbolts 0, passed between the poles of the magnets, the poles of the said magnets having their edges toward the flow of the grain in th trough, substantially as described.
2. A magnet for grain or conveyer spouts bent at a right anglc'to the Width of its material into two arms, so as to intercept a current of grain, 820., in two places, (across the line of said current,) in combination with the shield 0 and armature 13, substantially as described.
3. A magnet for grain or conveyer spouts bent at a right angle to the width of its material into two arms or poles, so as to intercept a current of grain, &c., in two places, (across the line of said 'current,) in combination with shield O, armature B, and-trough or spout A,
substantially as and for the purposes described.
4. The combination of the armature B, shield O, and trough A, substantially as described.
5. The construction and arrangement of the trough A, armatures B, shields O, magnets D D, confining-bars E E, bolted together and resting in sockets in the sides of the trough A, as described.
In testimony that I claim the foregoing l have hereunto set my hand this 18th day of July, 1879.
