JAMES w. LE GORE, 0E LE GORE, MARYLAND.

DISTRIBUTER.

To all whom it may concern:

Be it known that T, Janus lVrLu Gone, a citizen of the United States of America, and a resident of Le Gore, in the county of l rederic.k and State of Maryland, have invented certain new and useful Improve- IIIQIItS in Distributers, of which the follow- -ing is a specification.

My invention relates to (:listributers and is especially adapted for sowing hydrated lime and other comparatively fine material. Con siderable difficulty has been experienced in the effort to distribute hydrated lime for the reason that it sticks to any surface with which it comes in contact and does not slide readily and because it tends to become planned in the feeding devices and to clog the same. Furthermore, great difficulty has been experienced in securing a uniform flow at the desired rate. In order to overcome these difficulties I have devised a construction in which the ressure of the lime in the hopper is taken off from the feeding devices by a pivoted supporting shield or deflector and in which the sides of the hopper which are connected theretoare pivoted so that the parts named are free to vibrate or may be positively vibrated by the operator to promote the flow. of the material.

As will more fully appear later on in the specification I greatly prefer to so arrange the parts referred to that the slant of a given side of the shield and the slant of the side of the hopper facing'it' may be increased simultaneously. This will obviously immediately increase the flow on the side in questlon owing to the increased steepness of the adjacent sides.

()ne of the principal objects of the shield or deflector is to enable a large quantity of material to be carried in the hopper and yet to permit the feeding device or devices to operate freely. These devices may be of any suitable sort, whether rotatable or otherwise,

although I prefer to employ a rotatable reel. The shield is located above the reel and thus holds the material off from it preventing jamming of the material, and leaving the reela space within which it can rotate freely, the material being fed to it only to the extent desired. The shield may be adjusted vertically so that the depth of the ma.- terial in the reel may be yaried.

Other features of my invention will be hereinafter described and its nature will be made more fully to appear.

' My invention, therefore, consistsin the invention described in thespecification, illustrated in the drawings and more particu larly pointed" out in the appended claims.

Referring to the drawings Figure 1 is a perspective. View of the distributor. Fig. 2 is a transverse vertical cross section. Fig. 3 is a longitudinal vertical section. Fig. 4 is a transverse vertical section of a modification of the invention, and Fig. 5 is a detail of the slide for controlling the delivery openings. Fig. 6 is a detail perspective.

My distributer is provided with a suitable frame conveniently constructed of beams 'l which run crosswise of the machine and of beams 2 running at right angles to the beams 1. This frame is mounted on the axle 2% which is provided with wheels 4. The usual tongue is secured to the frame. Upon the frame thus described is mounted the hopper wherein particularly my invention consists. On this hopper and frame are supported the. seat bar and seat 5. The machine is usually some sixor eight feet. wide and it is convenient to provide the hopper with a trans-= verse partition so as to make it practically. two hoppers arranged end to end. This is the arrangement illustrated, though I do not of course wish to limit myself to it. In the double hopper thus explained, 6 are the ends and 7 is the central partition which virtually forms the inner end of each hopper. Through these ends and partitions extends the axle 3 on which are fixed feed reels which 'rot-ate therewith. These reels are made up of disks 8 located at con'lparatively short distances along the axle and supporting in grooves at their peripheries rods 9 which I have found it preferable to make conical in cross section, the apex of the cone pointing outward, although the rods may be Specification of Letters Patent.

cylindrical or of other suitable shape. The 1 reel is so located that the path of the rods is close to the bottom.

As stated each of thehoppers illustrated (see particularly Fig. 2) is complete and a description of either will make clear the important features of my invention. The hopper, or each hopper ifthere are two, is in the preferred form of my im ention, provided with an upper stationary hopper section having sides 10; Tmmediatcly below this stationary ho per section is a lower hopper having si es 11 pivoted at their ated by the hand lever 17 mounted within I convenient reach of the driver, through suitwhich are adjacent to each ot able connections as the lever 18 pivoted to move in a horizontal plane.

Above the feed reel and having its axis parallel thereto is pivotally mounted a sup-- porting shield or deflector which in my preferred form has two diverging downwardly slanting sides 19, 20, the upper edges of er, although they do not necessaril meet, and are di-' rected toward the escendin material. The sides of the shield are il ustrated as tied by rods 28' into a strong structure. This shield is so mounted as to be adjustable vertically. This may be accomplished in.

any suitable way. vAs shown (see particularly Fig. 6) bearing blocks 21 in which are mounted the pivots 22 of the supporting shield are located to slide ingroov'es 23 in the ends 6 and artition 7. Rods 24 having their upper en s 25 screw-threaded-are attached to the bearing blocks and nuts or hand wheels 26 are provided for manual adjustment, the rods passing up through the supports 27 Each of the slanting sides of thls supporting. shieldor deflector is connected to the pivoted hopper side which faces it suitably by pivotal connections 28. If desired, in order to increase the range of adjustment or movement, these connections may obviously be made extensible in any. well known way. An operatin rod or handle 29 is attached to each shieId and forms a convenient means for tilting it in either direction about its pivots. The operating handle may of course be located on either ho per side instead of on the shield. In or er to ermit the movement of the pivoted sides of t e ho per without the escape of any of the materia the partition 7 and the ends 6 are extended farther than the greatestwidth of the lower hopper section.

The operation of the'apparatus is as follows: Material being placed in the hopper flows outwardly at the bottom of the upper stationary hopper section, the main body of the material being supported by the shield or deflector which prevents the material from filling up the reel and packing within and about the same and leaves it a space in which to rotate freely. The material having as stated flowed outwardly below the lower end of the upper hopper section into the wider upper endo-fl the lower hopper section rests against the slanting hopper sides and the to turn that side of stantly increased by toward the side in question.

slanting sides of the shield and flows by gravity between the-same into the reel and the lower part of the hopper filling the reel to the desired extent, this being determined by the relative position of the shield and reel which by reason of theadjustability of the shield may be varied within such limits as seem desirable. The sides and shield are the frame these parts'are vibrated slightly and the flow of material thus assisted but not unduly hastened. No lock is necessary to keep the parts in proper position since the sides and shield are connected and since the construction as. shown in Figs. 1, 2 and 3 is symmetrical, the weight of the material acting to keep the parts in proper position. If more material accumulates on one side than on the other the shield and with it the corresponding side of the hopper to increase the slant of both and restore the normal condition.

Should the material become jammed on either side the flow on that side can be inmoving the handle 29 The effect of this movement would .be to immediately increase the steepness or slant of both the side of the hopper and of the surface of the shield facing it. This would result in an increased flow, the material tending to slide more easily from the steeper surfaces. In additionthe parts may be so related as not only to increase the steepness of the facing parts referred to but to increase the distance its greater weight tends pivotally mounted so that by the jolting of j between the side'and the adjacent face of the shield. This can be done by so locating the points of to do more than vibrate and release the shield, although its operation can of course be suited to'clrcumstances, The division of the hopper into two end to end sections has the advantage of enabling the flow of each .of these'two hoppers to be separately-regulated, and prevents the material from sliding toward the lower end as might otherwise be .the case in work on side hills.

M invention is susceptible of various modlficationsand in Fig. 4 I have shown a modification'which, while far inferior to the form illustrated in the other figures, may yet be used. In this construction one only'of the 110 )per sides 11' is pivoted. The shield has only one side 19' which is pivoted at 22' to the stationar part of the ho per. The pivoted side an the ivoted shie d are connected together byt e ivotal connections 28 An operating han le 29 is'provided.

connection on the sides of the hopper and on the sides "of the shield as to The parts may be so proportioned and located that without any stop, they will stand normally in proper position when the hopper is full of material, automatic dumping being prevented in this way. \Vith this arrangement the flow may be increased by sinmltaneously moving the side and shield about. their pivots to increase the slant of both. I have, however, illustrated a stop 30 against which the under side of the shield 19 ordinarily rests. \Vhen it is desired to accelerate the How of material the side and shield. are turned about their pivot-s to raise the shield. 'lhey are then released and the shield allowed to strike against the stop jarring the material and incrcisingthe flow.

it is believed the advantages of my invention are obvious from the foregoing description and the accompanying drawings; yet it will not I 1 amiss to state that the peculiar position and construction of the deflector or shield prevents the material from packing by producing an empty, vacant space beneath it at the top of the reel, thus enabling the crowded material to loosen and drop, by gravity, direct into the reel or feeding device and thus constantly avoidingthe tendency of the material toovercrowd or pack in the machi1{1e.- By the supporting shield covering and. protecting the feeding device the material is kept loose so that, by

- gravity, the material is moved regularly into the reel or feeding device. The hollow space produced by the shield prevents any of the surplus material from becoming packed, as the weight of the material prevents it from rising up and filling the empty space above the reel or feeding device; so that the mass is kept looser at the bottom than at the ton of the hopper, which is impossible under ordinary condition or construction of hoppers.
