LOUIS C. VANDEELIP, OF ELKHART, INDIANA.

PNEUMATIC CONVEYER.

Application led July 27,. 1916, Serial No. 111,573.

To @ZZ whom z' may concern Be it known that I, Louis C. VANDERLIP, a citizen of the United States, residing at4 Elkhart, county of Elkhart, State of Indiana, have invented new and useful lmprovements in Pneumatic Conveyers, of which the following is a specification.

This invention relates to pneumatic conveyers wherein fluid under pressure, such as steam or compressed air, is introduced to a pipe conduit interior to kconvey loose and disintegrated materials such as ashes, sand, gravel, and the like.

An object of my invention is the production of an improved device of the class described which may be connected at both ends with straight piping for a conduit line for straight away conveyor work, thereby eliminating elbows, bends, etc., from the conveyer line. Another object of my invention is the provision of improved means for the introduction of fluid under pressure axially of a straight conveyer line, whether ina horizontal, perpendicular or inclined position. And another object is the production of aV chambered fluid pressurenozzle carrier in which the fluid pressure chamber -is flattened, or elongated, to reduce thetransverse displacement of the nozzle carrier within the conveyer line. And still another object is the provision of means for protecting the nozzle carrier against wear due to the abrasive action of the materials conveyed. And a still further object of my invention is the enlargement, or bulging, of the main casing thereof j adjacent the nozzle carrier to facilitate the movement of the materials past the nozzle carrier.

(.)ther objects will be mentioned and described from time to time herein.

The preferred embodiment of my invention is clearly shown on the accompanying drawings in which, Figure l is a longitudinal section in elevation; Fig. 2 is a section on the line 2--2 of Fig. l; Fig. 3 is a section on the line 3--3 of Fig. l; and FiOf. l is a sec'- tion on the line Li-4 of Fig. l. bimilar numerals of reference refer to similar members and parts of members throughout the Vseveral views on the drawings.V

Referring to the drawings in detail, the numeral l indicates a channeled body member provided with suction intake opening 2 and an outlet opening 3 at the opposite end and preferably in axial Y alinement, and adapted to be introduced in a pipe conveyer line intermediate its extremities, or to have Specification of Letters Patent.

a suction pipe fastened to intake opening 2 anda discharge pipe to opening 3. The numeral el indicates an opening formed in the wall of the member l to permit of the introduction of the nozzle carrier 5 provided with the projection 6 arranged within the interior of the member l, and which is provided also with the steam chamber 7 which is flattened, or elongated, to minimize the f transverse displacement of the carrier 5 `and the projection within the pipe member l. The chamber 7 is also enlarged somewhat in area, in the direction of the elongation, to provide ample steam supply and the maximum pressure thereof at the steam nozzle hereinafter described. The upper end of the steam chamber 7 is provided with an inlet opening 8 which is in communication with a steam supply pipe 9 leading to any suitable source of steam. By elongating the steam chamber 7 and making the side walls thereof` of reasonable thickness the projection 6 displaces the minimum space transversely of the member l, thereby facilitating the movement of the conveyer contents past and around the projection G. The numerals l0 and il indicate flanges of the nozzle carrier '5 adapted to be fastened to the base l2, of member l, by bolts 13, 13, the flanges being suitably apertured `for that purpose. The numeral 14 indicates an aperture formed in the projection 6 adjacent its lower end and adapted to receive and rigidly carry the steam nozzle l5 which is preferably placed in axial alinement with the opening 3 of member l, and which is adaptedto introduce the fluid under pressure to the conveyor pipe interior toY create the necessary suction for the movement of the materials therethrough.V The nozzle l5 may be fastened to the projection G in registration with the aperture 14 in any suitablemanner, but the preferred method is by bolts, screws, or screw threads on that portion thereof within the opening 14. ing end of said nozzle l5 rigidly held in substantially axial alinement with the discharge opening 3 of the member l the wear on theV The projection 6 of the nozzle carrier 5 is,

provided with an inclined, or slanting, wall G to which is detachably fastened the inclined wear plate 16, the latter being held in .By having the Vissubody member projecting into llying the lower end A member removably position by a bolt, or screw, 17 engaging the iiange 10. The wear plate 16 is provided Vwith a forward extension portion 18 underof the projection 6 tov protect the latter against abrasive action of the conveyer contents. The inclined wear plate 16 isl provided with a pointed end by beveling the surface thereof as at 18', 18, as indicated in Fig. et, to deflect the moving materials and to offer the minimumamount of resistance to the passage thereof. Being detachable thewea'r plate '16 may be removed and another substituted therefor when worn out. `To further facilitate thematerials past and around the projection @where coarse ashes and heavy clinlrers are being handled by the conveyor, the bottom and side walls of the body member are bulged outward at 19 and Q0, respectively, adjacent the projection 6, thereby increasing the cross-section area thereof.

A suitable hand hole may be made in the member at any desirable location either for inspection thereof or for the introduction of tools to the interior thereof for any purpose. Y
