Application 'April 29, 1933,, Serial no. 668,557

' -12 Claims. (c1. 221-419) This invention relates more particularly to fertilizer depositors of the typewhich deposit a material at some specific location as distinct from the general class of scattering apparatus.

It is, therefore, among the general objects of the invention to provide a simple, effioientand inexpensive device for depositing at .a specific location a predetermined-quantity of fertilizing material. 7

Another important object is to provide an apparatus for making a sub-soil deposit such that the fertilizer will be wholly deposited at a preferred definite location preferably in the neighborhood of the particular food absorbing portions of a trees roots.

Another important object is ta provide adevice for depositing a predetermined amount ;of material as distinct from depositing apparatus which depend upon the accuracy andcontrol of the operator for measuring- ,at each use ;the.guantity of material deposited I Another object is to provide an instrumentality which is lightand compact without the Sacrifice .of strength, durability and capacity, thus to provide ready portability while in use .and also to provide minimum weight and size in shipment or transportation from one field {of operation to another.

Numerous-other objects, advantages and .novel features will be apparent from a further -;consideration of this description and of the accompanying drawings. a i v Briefly and generally stated thatform :of the invention here described by way -.of illustration consists of a standard orv support {constituting a skeleton frame, the same-being suggested :as formed from round stock and supporting ,at its top a bag or hopper by the medium ,of a'foldfllble ,member. 'I'he lower end of the standard construction is secured to .a valve ,chamber body ;to the upper end of whichrthe bag ,or hopper is ,se-

cured. A discharge nozzle is preferably ,arranged in connection with the valve body so as ito provide for an inserted depositlof the'materialarather than a mere discharge which might beascattered. ,Animportarrt feature of ithe invention is1the waive mechanism and its operating-means whereby the proper placingof the devicecoupled its own weight acts to discharge a -''predetermined quan tity' of material beneath the ground surface. The structural details by which'one preferred embodiment of theinvention is accomplished will be hereafter referred to.

In the drawings:

Fig. 1 is a side elevation of .a preferred form of the invention.

Fig. 2 is a frontelevati-on of the same.

,Fig. 3 is a top plan view.

Fig. 4 .is a detailed vertical section of the valve chamber with the parts in material depositing position.

Fig. 5 is a detailed front elevation of the portion shown in Fig. .4 and Fig. 6 is a section taken on lines 6-5 of Figs. 4 and .5;

From a consideration of the drawings it will be seen that economy of manufacture, lightness in Weightand simplicity of operation are provided by .a minimum number of parts the essentials of construction being provided by merely three parts namely, the standard or frame, the bag or hopper and the valve chamber and its valves and operating mechanism.

With respect to the frame, reference may :be

had to the numerals 10 which indicate a pair of supporting .or frame rods preferably of .hollow construction, The rods lll extend in parallel from the valve body upwardly their upper ends being provided with clamping members M secured thereon by nuts [2. Each of the clamping members ;I.l receives one .end .of oneof apair of bag or hopper supporting handles 13 each of wh ch are .of right angularly disposed rod construction, their outer ends being joined by across bar .14 secured therebetween .as vby the screws l5. The center ,portion :of the bar 14 may be depressed as at 16 sons to provide .a recess or depression in the outline of the bag ,or hopper which .may :have the dual purpose :of forming a configuration suitable to conform with a tree trunk vor post against which the device may be rested or which may also conform with the body ,of an operator ,to facilitate his holding and operating the device.

I .have herein referred .to the fertilizer ,con-

.tainer as .a bag or hopper. Obviously, the invention is .not restricted to the form .of such container and if desired a rigid hopper ,may be employed. However, I prefer to usea fabriczpr other pliable bag as indicated by numeral I].

The bag 11, .,at least the lower end of which :is vof generally ,conical formation, may .be =cqn en =ientlysupp0rted from the rods L3 and ,bar 1.4 ,by

the insertion thereof through tubular hems ,formed in theedgeoftheopen mouthof theibag.

The fold formed tunnel 18 receiving .the ,bar .14 while the rear ends of the rods 13 are recessed vthrough similar folds l9 and the .opposite ends of .the bars are received through folds 20. Inter- V mediate the folds .19 and .20, the rods extend .out-

. valves 3| and 32.

wardly from the bag circumference so as to provide convenient hand grips 2|. By this arrangement and through the use of flexible material for the bag it will be seen that when not in use the handles may pivot in their sockets formed by members ll thus to fold to the dotted line position shown by the arrow in Fig. 1. By this movement it will be seen that the device may fold to peculiarly small dimensions for purposes of shipment and transportation. The lower end 22- of the bag as well as the lower ends of the supporting rods is secured to the valve body. The valve body, generally indicated by numeral 23 is of substantially simple cylindrical form, its upper end being flared as at 24, and receives therein a similarly formed cup of leather 25 which is bolted thereto and which in turn is joined to the neck 22 of the bag thus to provide a flexible and yet leak proof and durable juncture so as to provide a free passage for material from. the bag to and through the valve chamber.

The lower ends of the rods l0 extendforwardly near their lower ends as by the bends 26 and their extremities 21 extend through and are coupled rigidly with the valve body 23 by reception through the apertures of

flanges

28 and 29, nuts 30 acting to secure them rigidly in position thus to provide a strong, simple, easily assembled and durable combination of parts.

The valve body 23 is illustrated as being formed of a cylindrical central body, the flaring upper end and the slightly restricted depositing tube parts being secured in rigid assembly by the arrangement of associate parts. However, the specific detail of formation is a problem more directly of production. Suflice, it therefore, to consider the same as a unitary member either so cast or fabricated from various parts.

Within the cylindrical central body portion of the body 23 are disposed two spaced butterfly The upper valve 3| controls the passage of material from the bag to the valve body while the lower controls the discharge of material from the apparatus through the discharge tube 33.

The stems 34 of the valves extend through the walls of the body 23 and each are provided with cross levers 35 the opposite end of each lever being joined by a spring 36 thus to maintain a normal tension urging both valves in closed position. The other end of each lever 35 is provided with a projection 31 each of which is in V the path of upper and lower actuating

pins

38 and 39 respectively which are carried by a reciprocating plunger 49 the upper end of which is slidable in the flange 28 while the lower end is secured to an operating shoe 4| which encircles the tube 33 and which is urged downwardly by the pin and spring construction shown in Fig. 5. The tubular formation of the rods Ill accommodates this arrangement of parts. It will be seen that this construction provides the upwardly-extending pins carried by the sides of the shoe 4!, which fit into the lower tubular ends of the rods [0. The rods enclose therein the springs shown in Figure 5, which abut the upper end of the pins carried by the shoe, and. which, thus, tend to normally urge the shoe in its most downward posi-' ferred arrangement is here shown by which the insertion of the discharge tube in a preformed receiving hole will automatically discharge an amount of fertilizer measured by the capacity of the valve chamber between the valves thereof. The normal inoperative position of parts is shown in Fig. 2, with the shoe 4| extending downwardly through the spring pressure and thus the rod 40 in lowermost position, the upper valve will be held open against spring tension through the downward pressure of pin 38 on its arm 31. The same spring pressure acts to maintain closed the lower valve 32, the operating pin 39 for which is normally below and out of engagement with its arm 31. Thus normally the fertilizing material will fill the valve body to the point of the lower valve.

In operation when the discharge tube is inserted, preferably in a preformed hole but possibly by pressure the shoe 4| will be supported by the ground surface so that movement thereof upward with respect to the body and in opposition to its spring pressure, will take place. Such movement releases pin 38 from the cross lever of valve 3| and the spring pressure thereupon will close this valve as a continuation of the upward movement of rod 40, its pin 39 will raise projection 3'! of the lever controlling the lower valve which will thus open emitting the material which has been lodged in the valve body, thus discharging automatically below the surface of the soil 2. measured quantity of fertilizing material. Means may be provided such as the push-pin 42 for rendering the valve mechanism positively inoperative when desired; thus avoiding accidental discharge of fertilizing material while the hopper is being refilled or While the device is being carried.

The pin 42 is held against accidental movement by a spring 44. When the pin 42 is moved inwardly as shown in Fig. 1, it lies in the path of the projection 43 of the lower end of the valve chamber 23 thus preventing relative movement of rod 40 with respect to the chamber. When the device is to be used, the pin 42 is moved outward as shown in Figure 4, thus permitting free movement of the part.

It will be understood from this description that various arrangements of the actuating means may be employed. For instance, if the upper valve be held open or removed, the deposit of material will be commensurate with the length of time the device is held in its inserted position. Conversely, if the upper valve is caused to be closed by the downward movement of the rod 40, the device may be adjusted to discharge an amount something less than the valve body ca-. pacity. Also, by a downward extension of shoe scope of the invention as outlined in the append-.

ed claims.
