T0 aZZ whom it mag concern."
Be it known that I, J OHN W. POINDEXTER, a citizen of the United States, residing at Gynthiana, in the county of Harrison and State of Kentucky, have' invented certain new and useful Improvements in'Seed-Tubes for Grain Drills, of which the following. is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification. My invention relatesto seed-tubes for grain drills of that class which .are composed of coiled wire; and it has for its object the'pro duction of a tube which shall be self-cleaning and cheap in construction, as well as efficient in action. The noveltyof my invention will be heree inafter more fully set forth, and specifically pointed out in the claims. 7 q
In the accompanying drawings, Figure 1 is a side elevation of a graindrill tube embody-I] ing my invention in its preferred form. Fig. 2 is a corresponding view of a modification. Fig. 3 is a correspondingview of a still fur ther modification. a 3 L The same letters of reference are used to indicate identical partsrin all the figures.
A represents a closely -coiled-wire tube of erably of the shapeshowmand having at its lower end an open 'spiral'B," formed integralwith the rest of the tube A.
The purpose for which the open spiral Bis threefold. First, it prevents the lower end of the tube from becoming stepped up with mud or earth while working in the field if the ground is slightly soft or wet, which is a very great advantage over tubes now inuse, for they frequently 'become cloggedor stopped up, thereby preventing seed from-being sown in the ground. In my construction if a piece of mud or earth lodgesin the lower end of the open part of the tube the grain can still pass out through the sides thereof and the movement of the tube within the bootof the grain-drill will soon dislodge theobstruction and it will fall out, thereby leaving the tube free and open. The second purpose for forming the open spiral B on the end of the tube A is to make a self-cleaning drill out of the machine to which it is applied. Frequently into the opening through which the seed has to pass, thereby rendering that shoe useless ing in the shoe andremoves the obstruction.
Formerly if this was done ,it was at the risk I of plugging up the lower end of the seed-tube, as .will be readily .understood. The third purpose for forming. the open spiral onthe.
lower end of the tube is to supply a guide for the seed-tube in case theshoe should drop into a hole in thelfieldfas is frequently the case, and on account of the self-cleaning properties of my tubeit can be made longer than ordinary tubes, and so accomplish the in using drills in the .field, and more especially in damp or sticky soil, the shoe or boot 3 be omes stopped up by the soil working up result as stated above namely, preventing shoe in case the latter should drop into a hole,
and thereby savingtime and labor to'replace "the tube within the shoe.
vantage of the open spiral is that if the shoe I should drop awayfromthe end of thetube and in coming back should strike the end of the tube the spiral B'will act asa spring to throw the tube eithenintol the boot or entirely away therefrom, and" sci-prevent any danger of breaking the seedcup from the sudden jar of having the boot strike the lower end of the tube, as frequently happens. with tubes now in use.
While I prefer to make; the open spiral B A still further ad.-'.
the tube from swinging out away from the v plished by using the shape asfshown at B, n
Fig. 2, or thatshown at B Fig. 3, which are modifications of my present invention,orany other shape that will-accomplish the same result in substantially the same manner.
Having thus fully described 'myinvention, I claim 1. In a grain-drill seed-tube of the cheat ter described, the combination with a closelycoiled-wire tube, of a downwardly-projecting cleansing portion secured to its lower end,- substa'ntially as described. 7
2. Ina grain-drill seed-tube of the character described, the combination with a closely- 6o end of the tube passes out through the opencoiled-wire tube, of a downwardly-projecting per portion and adapted to clean itself and cleansing and guiding portion secured to its the boot and also to form a guide for itself lower end, substantially as described. in the boot, substantially as described.
