CORN STR-INGER.

Application filed October 24, 1921.

To 0,7? fir/1 ein if may concern.'

Be it known that l, @Hannes Mausi-i: PUT- NAM: a citizen of the United Stat-es`r residing` at nimm in the county of Gratiot and State of /Iichigan. have invented certain .new and useful improvements in Corn dtringfers; and 'l herebyY declare that the tollowinq is a full, clear, and exact description thereof, reference being` had to the accompanying drawings. which form part ot the speciiication.

My invention relates to improvements in corn stringere wherebyjl amable to string' seed corn rapidly and without bruising' same.

lilly device provides 'for weavingr the corn between strings iu such a. manner that the strings are drawn taut but not tight enough to torce their way between the grains or bruise them.

'Referring to the d 1awings: 1 shows a vertical cross section of my corn Stringer. Fig. 2 is a. horizont-al cross section on the line2-2 ot Fig. 1. Fig. 3 is an enlarged portion in cross section showing how the strings .pass through the slides.

Referring more particularly to the. drawings; 10 and 11 denote complementary sliding` trames attached to eachother by rope 12 which Ipasses over pulley 13 which pulley is mounted on stationary 'frame 111; cross bars 15 are att-ached to this frame and slidablyv hold the slidingT frames 10 and 11 in proper relation to said stationary frame 14. Sliding frame 10 is provided with horizontal bushings 16. Sliding frame 11 is provided with a screw eye 17 bent at right angies. y

A t the lower end of the sliding trame 1u is attached a weight 18 to counterbalance a treadle 19 attached by link 20 to the lower end ot slidingtrame 11. The treadle 19 swings upon hinge 20% att-ached to the supporting trame of table 21. A coil spring 22 is attached to the table 21 and the treadle 19 aiding in the quick return ot the treadle to a normal position after being depressed in operation of my device.

The slanting table 21 is secured to the stationary frame 14 by cross bar 23 and slantinpsupport 24. Slightly above and'on the opposite side trom the table 21 is tension table 25 secured to stationary frame 14 by means of braces 26. Upon the tension table 25 are mounted four metal spring Specicaton of Letters Patent.

plates 2? which are bent so as to be held in hinge-d position by staples 2S. bolt 29 passes through the table 25 through a hole provided in plate 2T' and there sur- ,mounted by a coil spring' S150 held in proper ljustable tension by wing' nut 31. lplates 2,1 rest upon a dat metal bar Attached by staples to the table 25 are guides 33, 341, 'l'and 3G. rllhe guides are provided with a bent end which. keeps them from slipping out 'trom between the staples in which they are hing-er and also limitthe downward motion ot the lQjuide. The outer portion oi these guides torni a loop thiioug'h which the rope or twine used in my device is threaded. rThe guides direct and also take up any slack in the twine.

ln the operation of my device four halls ot rope ortwine denotedby 37 are placed upon the Aqjround or floor, the ends of said twine being' passed through'holes 38 in tension table 25. thence over the flat metal bar 32 and under spring' plate 27. 'thence the twine is threaded respectively through the fluide 33. B41-, 35 and 3G. The twine passing through guides 33 and 3G is threaded through .screw eyes 1T inthe sliding1 trame 11. rPhe twine passing; through guides 34 and 35 isthreaded through bushings 16 pror 1vided in sliding; trame 10.

The table 21Y provided with guide rails 39. lt will be noted that at the point 4-1 where the operator passes the ears 0i corn denoted by #10, between the cords 9,?. this rail 39 is omitted to allow the corn to be quickly slipped onto the table. After an ear of corn has been placed between the cords the treadle 19 is pressed downward by the toot ot' the operator this causes the sliding,r iframe 11, to descend and its complementary sliding tame 10 to rise, thus carrying; two cords up l:ind two down, another ear of corn is then passed between the cords in their new position. the operator then releases the pressure of his toot and the complementary sliding trames resume their original positions assisted by weight 18 and spring` 22.

This operation is repeated nntil the desired number ot ears have been strung, the cords are cut and the strung ears are removed and placed to one side preparatory to removal to the drying house. The out ends ot the twine are again knotted and the process again repeated.

It will be seen from the above description that the number of ears strung per dayv is only limited b v the speed at which the operator can feed the ears. The slant of the table 2l aids in sliding or pushing the corn down the table when strung.

It Will further be seen that the corn may be strung as tightly as desired by regulating the tension of springs 30 on the tension table together With the pushing pressure exerted by the operator in sliding the strung corn down the slanting table 21.

It is apparent that my device provides for Stringing the ears of corn with even tension and that the number or' ears strung have little or any effect upon this tension, the Weight ot' the strung ears being supported upon my slanting table. The ears of seed corn are strung in parallel relation to each other there being no limit to the number that may be strung in any one series.

It is also apparent -from the construction and plainly shown in F ig. l that the slanting table 2l is slotted so as to permit the cords 37 to pass beneath the level ol salu table on the down stroke ol the sliding frames 10 and 11 respectively. This it will be seen permits the ears of corn to rest upon the surface of the said table and at the same time slide between the said cords.

Claims:

l. A corn Stringer of the class described comprising an upstanding frame, complementary sliding frames mounted therein, a rope connecting said Asliding frames, a pulley for supporting said rope mounted in said upstanding frame, a tension table attached to said upstanding frame provided with tension spring plates, bolts and springs, a slanting table opposite said tension table and attached to said upstanding frame,

strings threaded through said tension means and passed through said sliding frames in pairs respectively, a treadle hinged to saidl slanting table and attached to one oi said sliding' frames and a Weight attached to the other sliding irame whereby the movement of said treadle `will alter the relation oli said sliding frames and said Weight upon the release ot said treadle will return said sliding frames to normal position crossing and recrossing said pairs of string thereby Stringing ears of seed corn in parallel relation.

2. A corn stringer or the class described comprising an upstanding trame, complementary sliding trames mounted therein, a rope connecting said sliding frames, a pulley it'or supporting said rope mounted in said upstanding frame, a tension table attached to said upstanding frame provided with tension spring plates, bolts and springs, a slanting table provided With cord slots therein said table being located opposite said tension table and attached to said upstand- 'ing trame, strings threaded through said tension means and passed through said sliding trames in pairs respectively, a treadle hinged to said slanting table vand attached toone oi said slidingframes and a Weight attached to the other sliding frame whereby the movement of said treadle will alter the relation of said sliding frames and said weight upon the release of said treadle will return said sliding frames to normal position crossing and recrossing said pairs of string thereby Stringing' ears of seed corn in parallel relation. i

In testimony that I claim the foregoing as my own, I allix my signature.
