HENRY S. AYLING, OF CHICAGO, ILLINOIS, ASSIGNOR T UNITED CONVEYOR CORPORA- TION, 0F CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

CONVEYER FITTING.

Application led February 2, 1923. Serial lo. 616,607.

My invention relates to conveyer fittings and more particularly to pipe fittings used in connection with conveyers for ash or othei similar material.

One of the objects of my invention is to provide means for directing the incoming material flowing through theV fitting outwardly of the discharge end of the fitting.

Another object of my invention isto provide jet means for directing the ash through the fitting, which means Will comprise a plurality of nozzles and permita large saving in the amount of steam or other fluid required.

The invention has among its other objects the construction of the device described in which there will be but a small amount of Wear on the fitting, due to the movement of the ash therethrough, and in which the parts may be easily assembled and disassembled.

Among other objects of my invention, I have sought to provide a device of the above described, which shall he economical, efficient, convenient, durable and satisfactory L for use wherever found applicable.

Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the `art from the disclosures herein given.

To this end my invention consists in the novel construction, arrangement, and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts,

Fig. 1 is a longitudinal section the fitting;

Fig. 2 is a fragmentary enlarged section taken substantially on line 2 2 of Fig. 1;

Fig. 3 is a section taken substantially on line 3-3 of Fig. 2; g

Fig. 4 is a section similar to that shown through in Fig. 3 and illustrating a modification thereof;

Fig. 5 is a plan View of the parts shown in Fig. 4;

Fig. 6 is a sectional view similar to Fig ure 1 illustrating another form of the invention, the same being a section taken substantially on line 6-6 of Fig. 7

Fig. 7 is a sectional view taken substantia-lly on line 7--7 of Fig. 6;

Fig. 8 is a sectional view taken substantially on line 8*-8 of Fig. t), illustrating another form; and

Fig; 9 is a sectional view taken substantially on line 9-9 of Fig. 8.

In the drawings, wherein have illustratt-d the preferred embodiment of my invent-ion, 1 and 2 indicate the mating parts of a conveyer fitting of any preferred type. In the particular instance it is shown as an elbow fitting in which the member 2 is the wear-member, receiving the impact of the material thereon, and preferably renewable as shown. The fitting is cored out'to provide a chamber therein having an inlet end 5 and a discharge or outlet end 6. Flanges 3 are preferably provided at the inlet and discharge ends of the fitting for Vattachment to adjoining cooperating parts. In the form shown, theparts 1 and 2 are joined together along the line 4 and are held by bolts (not shown) or the equivalent. y i

In order to direct the incoming ash through the fitting and through Vthe pipe-line of which the fitting is a. part, I prefer to use fluid means, such as steam, or the like, for forcibly directing said material in the desired direction. The material of which the parts 1 and 2 are composed is generally very hard and difficult to machine and therefore I prefer to cast a softer member or plug 7 therein intermediate the inlet and the outlet ends of the fitting so that this plug may be machined for the reception of the jet-direct ing means. The purpose. of the steam jet is to induce a strong current of air through the system.

In the form shownrin Figs. 1, 2 and 3, a member 8 is threaded into the plug 7, said member having threads 9 thereon at one end for the purpose and being threaded at its other end, as at 10, for attachment to a suitable fluid-conducting means. The member 8 is arranged substantially in alignment with the axis of the discharge outlet 6 and is provided with a chamber 11 at vits outer end, said chamber communicating with a plurality of ducts 12 extending through the member 8 and their size and relative position may be arranged so as to best meet the existing conditions. The outer ends of the ducts 12 are preferably outwardly flared, as at 13, so that the Huid entering the fitting through the ducts will expand according to the physical law governing the expansion of the fluid used so as to change its pressure cation and individual nozzles 8 are arranged in the plug, as shown in Fig. 5.

It has been found by tests that when using the plurality of' jets or nozzles of' the types shown and described that there was ai substantial saving in the amount oi' steam required as compared to that necessary in the operation of the usual type having the single nozzle and that there was less Wear in the fitting. In other words, the plurality ot' nozzles properly spaced or located have a tendency to protect the Wear back or the point of Wear against excessive abrasion and also reduce the steam consumption per ton of material carriage. The spacing or loca- Y tion and number of jets may vary depending upon the pressure, material conveyed, type oi fitting or for other reasons.

Referring to Figs. 6 and 7 another torni of the device 1s shown in which 1 and 2 representany particular type of fitting to which the construct-ion is applicable, and represents chambered part connected with a fluid supply pipe 16 through which steam or the equivalent maybe admitted to the fitting. In this particular case part 15 is provided with a chamber 17 which communicates with the desired number of nozzles 18 distributed as desired. It may be mentioned that these nozzles generally may be distributed in various Ways. As shown they are distributed so that, to some extent, they have a tendency to deflect the material before it strikes the kWear back outlet but at the same times does not interfere With the entry of the material as it enters the fitting. A very similar result may be obtained in the case of the type of fitting shown in Figs. t and 5 if a portion oi the nozzles at one side o'f the plug 7 thereof is omitted. In other words a similar result can be obtained from the other construction shown. This has a tendency to prevent or reduce Wear on the Wear back.

In Figs. 8 and 9 in which 1' and 2 represent suitable fitting parts 2O represents a plug provided with a chamber 21 to which steam or the like may be admitted through the supply pipe 16. In this particular type the part is provided with a' port or steam outlet 22 which may be constructed in the form of a slot, as shown, or in any desired manner that will provide the desired results.

slot or arrangement of nozzles may depend upon the stea'm pressure employed upon the material to be conveyed, or upon the particular type of fitting, or the angle of discharge o'f the steam or fluid may be varied, that is relative the path of the discharged material or axis of the fit-ting; hence I do not Wish to be understood as inferring that the particular arrangements shown are the only possible ones.

Having thus described my invention, it is obvious that various immaterial modifications ma'y be made inthe same Without departing 'from the spirit of my invention;

hence I do not vfish to be understood as limiting myself to thei exact form, arrangement, construction and combination oit part-s herein shown and described or uses mentioned.

`What I claim as new and desire to secure by Letters Patent is:

1. A conveyor fitting comprising main body part provided with an outlet disposed axially thereof, and a laterally disposed inlet, a plug on said fitting provided with a plurality oi ducts therethrough to direct fluid into the incoming material to discharge the material through the outlet, said plug being disposed longitudinally of the main body part forwardly of the lateral inlet out of' the path of the material entering the inlet, one of said ducts being substantially in alignment with the axis of the outlet, and other of the ducts being concentrically arranged about `and parallel with said iii-st mentioned duct.

2. A conveyor fitting comprising a main body portion provided with an outlet disposed aXially thereof, and a laterally disposed inlet for the material, and means for directing fluid into the material in ai plurality of jets along lines parallel with and ott'- set from the axis of the main body portion, said means being disposed longitudinally of the main body portion'oil the fitting forwardly of the laterally extending inlet and out-of the path of the material entering said inlet.

In testimony whereof, IV have hereunto signed my name.
