y To all whom t may concerti:

Be it known that I, JAMEsA. DAvmss, a citizen of the United States, residing at Chicago, in the county of Cook andv State of Illinois, have invented a certain lnew and useful Improvement in Ash-Conveyer Systems, of which the following is a full, clear, concise, and exact description, reference being had to theI -accompanying drawings, forming a part of this specification.

This invention relates to ash conveyer s tems and broadlystated-is concerned with thevprovision of means4 associated with the pipe line of such a system arranged to permit the removal, replacement, and substitution of portions of the pipe line which in ,i the operation of t-he system become excessively worn due to the abrasive action of the ashes conducted therethrough, without materially disturbing the system or the line of pipe or conduit in which said portions are found.

Conveying systems of the class to which my present invention relates comprise metal conduits or pipes through whlch the ashes are conducted 0r moved by suction or draft of air created 'by steam jets or suitable blower or fan mechanism. While I prefer to employ my invention in connection with an ash convcyer of the steam jet type it is equally applicable to other systems.

In conveying systems of the class under consideration it often, in fact ordinarily, is necessary t0 provide both horizontal and vertical pipe lines and even oblique runs of pipe, wherefore it is very diiiicult to avoid the use of elbows or at any `rate more or less abrupt bends or turns in the pipe lines. As,

the practice in the past because of this excessive wear at the bends to provide elbows comprising removable sections or provided with removable wear liners or backs. It has been found, however, that the excessive direction of flow thereof is' abruptly changed or altered. It has been abrasive action of the ashes occasioned by an abrupt chan e of the direction in the pipe line is not con ned to the elbow or curved portion of the pipe but extends through the straight port-ion of the pipe for a considerable distance beyond the elbow in the direction of flow. This is probably accounted for by the fact that the ashes after leaving the elbow or curved portion of the pipe line do not immediately resume their normal flow along the axis of the pipe but are for some distance carried along in more or less violent contact with the inner surface of the In order to provide for the' wear which occurs just beyond the elbow or bend as just explained, the use of a short section or length of pipe that may be removed and renewed from time to time has been suggested. However, it is ordinarily no simple matter to remove such a pipe section from the other elements of the 'pipe line and this is particularly true when the removable pipe length is located in a vertical riser extending upwardly from a horizontal pipe line with which it is connected by an elbow or other curved pipe fittings. Heretofore in such a case the entire weight of the vertically disposed pipe line has been carried upon the removable pipe length and elbow with the result that in order to lremove the elbow or the aforesaid short length of pipe or to shift the position of the latter with respect to its associated pipe sections has necessitated the provision of special equipment of various kinds for temporarily supporting those elements of the conduit above the sections thereof that are to be removed, re-

j placed, or shifted.

or sections therebeneath, in order that the latter may be readily removed, replaced, or shifted with respect to the permanent conduit sections as conditions require.

My invention is fully set forth in the del.

' means for supporting Y steam jet type, I prefer is a side elevational view ofthe theline 4--4 of Fig. 3, and

Fig. 5 is a fragmentary view partly in ser tion and partly in elevation of certain parts of an ash conveyer system equipped with the devices of my invention.

Similar characters of reference refer to similar parts throughout the several views Referring lirst vto Figs. 1, 2 and 5, it will be noted that the ash conveyer system comprises cast iron pipes of suitable capacity, the abutting sections of which are provided with coperating iiang'es secured together in any well known manner, as by bolts passing through registering apertures -or slots in the coperating -anges The system herein shown comprises a horizontal run of pipe comprising a plurality of sections 10--10, one of which is shown in Fig. 2. Asis usually the case, the horizontal run of pipe is disposed in a trough or tunnel with the horizontal pipe sections 10-10 resting upon the tunnel floor 11 as shown. The horizontally disposed portion of the conveyer conduit communicates with a vertical riser and I prefer to aEord this com munication through a long radius elbow comprising sections 12, 13, 14 and 15, although my invention contemplates the use of any other form of elbow that may roverdesirable or expedient. The system being of the toprovide 'the elbow section 15 with a steam supply pipe 16 which communicates with a nozzle (not shown) carried by the section` 15 and discharging upwardly into the conduit.

The vertical riser comprises Va removable pipe length 17 and as many sections 18 as conditions require, in the normal operation. of the system the ashes are carried along in the horizontal run of the conduit toward the long radius elbow and out through the vertical riser and .other conduit elements (not shown) to a suitable discharge point.

As my present invention is concerned with the provision of and permitting the removal, replacement,v and adjustment of certain parts of the system shown in the 'accompanying drawings, it will be unnecessary for me to illustrate or describe other parts of the system, as the same are well known to to those familiar with the art to which the invention relates.' v

it being understood that 'and 18 or substitute another removable section therefor. Heretofore the pipe sections 18 and other conduit elements with which it connects have been supported by the section 17 and the elbow sections, with the result that when it has been necessary toremove the straight section 17 or one of the elbow sections, special and elaborate means has been required to support the elements of the riser, so that the parts which have been worn may be removed. My invention contemplates the provision of means constituting a permanent part of the system which contributes the required support to the conduit sections above the pipe length 17 and elbow and which carries the parts above the removable pipe length 17 independently of the elbow and pipe length 17 when the pipe length 17 or elbow or any section of the latter is to be removed.

The means for accomplishing the purpose just mentioned comprises a yoke or clamp arranged to embrace theirst conduit section above the removable p ipe length 17. Said yoke or clamp comprises a pair of strap metal members 19-19, each of which is conformed intermediate its ends to receive the cylindrical surface of the conduit section 18. The corresponding ends of the yoke members 19-,19are brought together, as is most clearly illustrated in Fig. 3, by bolts 20-20 and 201-20, the bolts 2O and 2Oa of each pair being spaced apart to receive between them one of the head pieces of a supporting standard presently to be described.

Disposed upon the floor 11 and situated on opposite sides of the conduit adjacent the elbow are the standard bases 21-21, each of which is in the form of an integral casting conformed to provide a cylindrical upwardly projecting boss 21a and an annular recess 2lb. The adjustable standard of which each base member 21 forms a part comprises a tubular element 22 which may be .a length of standard gas pipe having its lower end disposed around the boss 21a and disposed in the annular recess 21b of the base.

Disposed above each of the tubular elements 22 and in aXial alinement therewith.

24:a received by the upper end of its associated tubular element 23 and an annular re- 'ral casting comprising a cylindrical boss duit of the worn sections,

portion of each of the head cess 24" in which the upper end of said tubular element engages.` Formed in the` upper pieces 24-24 1s a transverse slot 24c which adapts the head to embrace the connected ends of the yoke or clamp members 19-19 intermediate the bolts 20 and 20, whereby said ends ofy the clamp members are secured toget-her.

Interposed between the tubular elements 22 and 23 of each standard is a. bolt 25 havlng its ends screw threadedl in opposite directions, one end of said bolt being freely disposed within the upper endof the lower tubular element 22 andits upper end freely disposed within the lower end of the tubular element 23. Threaded ,upon the bolt 25 of each standard are the nuts 2626, the washers 27-27 being interposed between said nuts and the lower and upper tubular elements as shown. It Iwill thus be seenthat adjustment of the nuts 26-26 with respect to the bolts 25 changes the effective length of the latter and thereby varies the height of the standard heads 24-24.

The vertical standards just described normally Contribute to the support of the conriser and hold it against lateral displacement. Whenever it becomes necessary or desirable to remove the conduit length 17 or any one of the elbow sections, these being the parts .which are subjected to the most excessive wear, the nuts 26-26 are adjusted to increasethe effective length of the bolts 25-25, thereby lifting the standard heads 24-24 and taking all of the weight of' the conduit section 18 and parts thereabove of'l' whereby the latter may be removed, inspected, readjusted or replaced 'with ease and without deranging the other parts of the system. A

It will be understood that the pipe section 17 may be either standard pipe orthat its walls may be of greater cross section than the other pipes constituting the conduit to compensate for the excessive .wear to which the pipe 17 is subjected in the tion of' the system.

It will thus be seen that I have provided simple and inexpensive means for spacing the permanent elements of a conduit riser from the worn parts .when said worn parts are to be renewed and for supporting the former independently of the latter, Wherefore it is possible to remove and replace the worn parts without deranging the permanent elements of the conduit.

While I have described my invention as applied to the conduit of a conveyer of the steam jet type, it .will be understood that my invention is not so limited but may be applied to various types of material conveyers.

What I claim as new and desire to secure by Letters Patent of the United States, is:
