As the air discharges from end 23,'it induces a flow of the grain'into and throughthe housingl As the grainproceeds to a point in advance of the end or nozzle 23, the air propels the grain.

and yet, I provide the, required extension of constriction to a point almost to the edge 11, oftop wall 7 As a result of this disposie tically the rear of the edge 11, of top wall 8. This disposition of partitions 24, forms chambers 28,.Wh1ch are dead chambers, without any function, but which are of such limited caacity thatwthey are not objectionable.

\Vith the structure thus far described,'unless it were shoved into the grainbody' sufficiently to fill the housing to, apoint sub-' stantiallyabreast of nozzle 28, the action of transferring would' start slowly. It would alsobe diiiicult to sustain operation. Therefore, to facilitate "priming, and -to adequately sustain operation, I provide'in the top wallS, a priming and auxiliary feed opening upwardlytoward the grain above the buried housing; It will be noted that dotted line A, shows that the nozzle 23 is sli htly in the rear of the farthest diametrical portion of of Fig. 8. This disposition, allows inost of the grain to be fed into the housing, in the rear of nozzle 23.

It will be assumed that B designatesthe bad order car and C designates the car in good order. 'The door openings of the re spective cars are designated at b and 0, the sliding doors at Z) and (1. Inside the side walls of thecarsfbo'ards b and c retain the grain or other contents of this character from leakingoutv In some instances, I can saw an opening in the bottom board, as indicated 'atb andinsert the. housing with the latter of the adjacent car C, as shown. 'A rip track air hose 19, which is aways'available,

is'connected up with its fittings with hose Now the valve 16, is opened, and the airunder pressure-induces and'forces the grain from housing 2, through the hose 4;,- into car C. It is desirable, although not essential, that the'end 3, should not be buried in the grain of car O, because no i of back pressure load imposed upon the in- V jector. However, inpmctice, Ifind that if the freeendB, is manually unrestrained, it

will wobble and wiggle under the action of the a rpressure to such an extentthat itcan hardly become buried." Thus, in practice,I

-, connection with each other.

I next wish to point out novel features of the invention whereby the action of the de vice itself, will act to bury the housing in the grain. i

In full lines in Fig: l, I have shown the housing 2, initially buriedbeneath thegrain level as shown by"dotted line E. As long as the housing is buried to the extent of getting opening 28, beneath the grain level,

this is sufficient. Itfwill also be noted that.

the metal edges 30, 12 and 11, will otter very little resistance to insertion of the housing as shown. In this inclined position shown in full lines,'the displacement of the grain into the housing, will act as a suction tend-T ing t-o draw thehousing'toafurther depth nto the grain as the latter enters the housmg. For instance, just as soon as the grain in the immediate proximity ofthe housing entrance, has entered the housing, a void is created which allows the housing to further descend. This, together with a sort of suc tion action, will cause the .housing'to sink gradually, lower in the grain body to be transferred, as the level of said body descends, and this is entirely automatic.

It willbe seen that the partitions 24, are so disposed and related with respect to the nozzle 23 as to efficiently initiate and sustain injecting action. Further, by reason of these partitions, I obtain the requisite restriction to obtain injecting. action and also donot require an abrupt convergence'otthe side walls 9, which would otherwise be necessary if it were not for" the partitions 24.

It will be seen that aside from valvec16, the whole structure is devoid of movable parts, all theparts being-rigid, and in rigid Such adjustment of the nozzle 28, lengthwise, to the required position with respect to the restrict-V use, i

ingpartitions 24, and with respect to opening 28, may easily beinade by turning the section 22 in' thejifitt'inglinto'which it is screw threaded.v r I From the foregoing description,it .will be Q is 'readily ha-n'd' portable, and in practical] clear that I have devised a mechanism which I have very greatly reduced the cost of transferring grain from bad order cars.
