JOSEPH LEWIS, or SOUTH EVANSTON, ILLINOIS.

PNEUMATICAPPARATUS FOR TRANSFERRING GRAIN.

SPECIFICATION forming part. of Letters Patent NO. 351,'783, dated November 2, 1886.

Application filed February 13,1886. Serial No. 191,836. (No model.)

State of Illinois, have invented a new and useful Improvement in Pneumatic Apparatus for Transferring Grain, of which the following is a specification.

In the Letters Patent to me of September 18, 1883, No. 285,047, there is shown a nozzle intended to be held in the hand during use in unloading or drawing grain from a car or other receptacle, such nozzle being provided with vent-tubes placed parallel to the nozzle and extending down to the orifice thereof, for the purpose of supplying air to the orifice and preventingchokingatthatpoint. Thisvented nozzle, while it effectually prevented'choking, is subject, I find, to another objectiouviz., that it so reduces the Sucking-power of the induced current in the pipe to which the nozzle is attached, and due to the elevating-blast in the mainelevating-passage of the apparatus, that the grain is not economically moved; hence I have been led to substitute for said vented nozzle the devices hereinafter described. I

Instead of relying upon the induced current of my said patent to suck up the grain into the same, (although such induced current may be and should be present when the nozzle is connected to an elevating-blast in the manner shown in said patent,) I furnish the. nozzle with an upwardly-directed blast or jetof air at a point just within its mouth, whereby to create the necessary suction at the mouth to draw in, and at the same time to propel, the grain on its upward course and prevent the choking. The primary feature of my invention consists in the combination, with the nozzle, of this blast thus delivered thereto in an upward direction and just within its month.

In order that the nozzle and its accompanying blast may be moved about in the car or receptacle and kept in contact with the grain, I make the grain and air pipes with which they are connected flexible, either by the use of universal joints or by making the pipes themselves of flexible material; and my invention.

In the drawings, Figure l is a vertical section of my invention. Fig. 2 is a like View of a'modification thereof. Fig. 3 shows a transfer-car provided with an air-supplying engine, 5

be inserted and moved about in the body of grain to be transferred from the car B or other receptacle. It is preferably cone or bell shaped at the mouth.

0 O is the blast-supplying pipe, terminating in thejet a, passing through to the inside 6 nozzle A. At the same time it propels the grain upward in the grain-tube and avoids any choking at the mouth of the grain-nozzle.

As the grain-nozzle and its air-supplying tubes must be moved about in the grain, I connect them to the stationary parts of the elevator or transfer apparatusbypipes which are flexi- I ble. This flexibility may be obtained by making the pipes themselves flexible or by form ing them of metal in sect-ions united by joints which permit the required movement-s. prefer to make one of the pipes at least partly of flexible material and the other of metal with the flexible joints, so that the latter may be made to project horizontally, and also be made to support and guide the other. in Fig. 1 the grain-pipe is made to embody a flexible or hose section, A, while the air-pipe is wholly metal, the latter being provided with a face-flange joint between the sections 0 and O, and a universal or globe joint between 0 the latter and post 0 In the former of these joints the ends of the pipe-sections are bent down and up so as to meet, and provided with flanges O and C", respectively, and are held togetherbyabolt, Cipassing centrally through 5 the globe O on the section 0, and an inclos- 10o ing-shell, G on the post, the former having a spreading mouth, O so the supply of air may Thus 8 5 be continuous, and the latter an elongated opening, 0, like that shown in Fig. 5, to allow the vertical movement of the pipe.

The air-blast may be introduced to the interior of post 0 and from thence into the pipe 0 G. Said post may also be capable of movement around its vertical axis. I obtain this freedom by providing the post with a stationary base, D, and secure i t thereto by a sleeve, D, inclosing said base, and secured to the movable post,as by bolts (2, and a central belt, I), passing through diaphragm D and the end of the airconduit E, connecting with the bottom of the post, and by providing thetop of the post with a globejoint, A, uniting it to the branch A, leading to the elevator-building or to the place where the grainis to be discharged. By widening the opening A" in the globe of this joint the conduit A maybe allowed to rise and fall without obstructing the passage through which the grain is lifted.

In the modification, Fig. 2, the grain-pipeis composed of two metal sections, A and A coupled together by a face-flange joint, A, and bolt, similar to that already described and shown in Fig. 1 as uniting the sections Quad C of the air-pipe. In this case, also, the nozzle A is united to the section A by a universal globe-joint, A, siniilarto thatat A in Fig. 1, so that the nozzle may be inclined in any direction and moved laterally, while the vertical movement is permitted by the flexible or hose section A, connecting the section A with the conduit A or globe-joint A, and pivoting said section A to the post at A. The blast pipe 0 0, used with the grain-pipe just described, is provided with a flexible or hose connection, 0*, extending to the post, and supported, if necessary, in the coupling A, as shown. The post in this modification may, as in the other case, form a part of the conduit for the air, and have a similar base, D, and be held thereon by a similar sleeve, D, secu red to or integral with the post, and bolt D In order that the attendant who guides the nozzle to the grain may not be obliged to sustain the entire weight of the nozzle and its connections above described, I provide a spring, F, extending from the sleeve 1) and supporting the pipes, as in Fig. 1; or, in lieu of the spring,a counterbalancewei ght, F, upon the arm F", projecting to the rear from one of the metal sections of pipe as, for instance, A"m'ay be employed, as in Fig. 2; or, if more convenient, the nozzle may be supported from the elevator building or tower.

The apparatus above setforth may be mounted upon a car, It, as illustrated in the several figures, or it may be stationarily located. It

may be employed to draw the grain from one car or vessel into another, or into or from the elevator, or from one bin or receptacle to another. It may be connected and deliver the grain to a force-blast apparatus, such as is shown in my patent already mentioned, or to a suction-elevator, such as is used with the form of apparatus shown in patent to me of October 23, 1883, No. 287,033. Vhen. mounted upon a car, the air-blast may be supplied through conduit E by the air-compressing engine II and its boiler II',placed upon the same car.

In Fig. a my invention is shown as taking the grain from the hold of a vessel, J, and de livering it .into the chute K of an elevatorbuilding, L. This chute may convey the material to the hopper M, from which it may be lifted to the upper part of the building or into connection with the discharge-pipe N, by which the car 0 may be loaded. If the grain is to be transferred directly from the vessel J to car 0, then the conduit A, instead of being extended to chute K, is simply carried to the inside of car 0.

In loading cars and vessels, especially when done through the roof or deck, a very eonveir icnt device for directing the flow so the grain may be evenlydistributed and leveled without shoveling by hand will be found in the discharge-nozzle 1. (Shown in Figs. 2 and 4.) Being provided with a globular enlargement, P, held in a globular shell, I, like the globe and shell A of Fig. l inverted, the nozzle can be given a wide range of movement, and the grain directed to any part of the room being tilled.

The discharge-pipe N may be supported from the building by a swinging bracket, S, so that when not in use it may be turned fiat against the wall.

The dotted lines in Fig. 4 indicate the range of movement permitted to the grain-nozzle, and the arrows in all the figures show the direction of the blast.

hen the inlet-nozzle pipes are properly supported by the spring or balance-weight, the nozzle may-be guided by a gentle handpressure into the grain, and by giving it a circular pendulum-like motion the drawing up of the grain will be greatly facilitated. The operation need be no more severe on the attendant than the use of a broom.

I claim-- 1. The combination, in a pneumatic graintransl'er zipprlr'atus, of the grain-pipe A A and nozzle A, made of metal and connected by flexible joints, as set forth, with the air pipe (3 c and its flexible or hose connections 0 substantially as specified.
