Application filed August 4, 1919. Serial No. 315,291.

To all whom it may concern: I

Be it ,known that I, LORNE A. GRIFFIN, a citizen of the United. States, residing at Evanston, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Ash-Conveyers, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a provide elaborate or special devicesfor sup:

porting the conduit elements other than the one which it is necessary to remove.

In ash conveyor conduits as heretofore constructed, the removal of one or more elements of the conduit removes the support of one or more of the elements of the conduit which are not removed, so that it has been necessary to provide elaborate and special devices for temporarily supporting the conduit structure when one or more elements were removed. This difficulty has been particularly serious when it has become necessary to remove a conduit, element forming a part of a vertical run of such a conduit.

These and other features of my invention are fully set forth in the following description wherein reference is made to the accompanying drawings, in which-' Figure l is a vertical sectional view illusv trating portlons of horizontal-and vertical.

runs of an ash conveyer conduit, together with a sectional right angle elbow affording communication between the same.

Fig; 2 is a fragmentary elevational view illustrating a modification of the arrangement shown in Fig. 1.

Fig. 3 is a view similar .to' Fig. 1 illustrating a conduit wherein the sections of which the horizontal and vertical runs are formed are semi-cylindrical inshape.

Fig. 4 is a fragmentary elevational view illustrating modification of the arrange ment shown in Fig. '3.

Fig. 5 illustrates the application of my invention to an arrangement wherein the vertical portion or user of the condult comprises two separate" passages, and

F1 6 1s a horlzontal sectional VlBW' taken on t e line 6-6 of 5 and'looking in the direction indicated the arrows.

Referring first to Fig. 1, the reference numerals '10 and 11 respectively indicate vertical and horizontal portions of a conveyer conduit which are connected by a right angle elbow '12. It willibe understood that that part of the horizontal portion of the conduit which has not'been shown leads from the boilers or other point'from which the ashes are to be conveyed and is provided with suitable hoppers-for introducing the ashes into the conduit. It will also be un derstood that the vertical portion of the conduit leads ofl' to an ash tank, or to any point where the ashes are to be deposited. Furthermore, if the system is of the steam jet type, the conduit at one or more points isprovided with a nozzle for discharging steam under pressure into the conduit in the direction of travel of the ashes to carry the latter throughthe 'conveyen, Since my present invention is concerned solely'with the construction and arrangement of the several parts of the conduit, I have not deemed it necessary to illustrate the hoppers, ash tank and steam jets in the figure now under consideration.

The vertical portion of the conduit illus trated at 10 comprises a plurality of sections, a, b, 0, etc., and a-d, b- -Zz, 0-0, etc. The elbow '12 comprises the curved section an and the bottom and'end sections designated' as y and a respectively, the several abutting edges of said elbow sections being connectedftogether by bolts 13 cooperating with apertured lugs 14.

Attention-is directed tothe fact that'each i of the sectionsa, 6, etc., and aa, b-b,

etc., of'which the vertical run of the con-.

duit consists, comprise two portions one of 'which has a circumference of a litt1e more than 180, the other portion being a little less than180 in circumference. Therefore,

in elevation, these pipe sectionsappear tobe substantially L -sh'aped.

t w l b in tedthat th upper portion f the curvedelbow section :1: and the intermediate shoulders of the elbow section a are conformed to cooperate with the lower end of the vertically, disposed section a,

the upper portion of the elbow section 2 cooperating with the lower portion of the section a-a to provide a cylindrical passage up as far as the-intermediate shoulders of the section a. The upper half of the elbow section 2 lies flush with the intermediate shoulders of the section a, and thus provides'an'annular surface to receive the lower portion of the section a-a' which cooperates with the upper portion of the section a 'to continue the cylindrical passage up as far as the upper end of the section a.

' The section b resting upon the annular support afiorded by the upper end of the sec tion a and the intermediate shoulders of the section a"a continues the cylindrical passage up as far as the upper end of the section a-a. The cylindrical passage is continued upwardly by L-shaped sections b'b, a, c0, etc., all'cooperating in the manner just described.

It will be noted that no one ofthe several sections of the cylindrical portion of the conduit depends solely upon any other section for its support. Thus, for instance, section a is-supported bythe elbow section as and by the intermediate shoulders of the elbow section 2. Similarly, conduit section aa issupported by the upper end of the elbow section z and by the intermediate shoulders of the section a.- 7 All of the other sections of the vertical portion of the conduit are, similarly supported, no one depending solely upon any other section for its support. W

So far as my present 1I1Ve1'lt/10I]. 18 concerned, the horizontal run of the conduit ,is desirably, but of course not necessarily,

. of the kinddescribed and claimedinpatent to James A.-Da.viess No. 1,278,869, and of course it will be understood that I contemplatescoring any of the grouted joints as described in the Daviess patent if that should be necessary or desirable.

1 The grouted or other suitably packed.

joints between the ends of theconduit sections and the surfaces adjacent thereto are trated.

protected by semi-circular bands- 15-15, the bands of each pair being secured together b suitable bolts 16-16 'as illusgrouting or other packing material in position, and also serve to retain the several conduit sections in proper relation to each:

. other.

With the arrangement herein shown, any section of the vertical portion of the conduit may be removed without withdrawing sup-'- hese bands serve to retain the port from any of the other sections. For

instance,.assume that section b is to be removed .for inspection, replacement or re-- I 7 pair. All that need be done is to clamp the bands 6 and f in the positions shown in dotted lines, remove the band d and loosen the grouting or packing material adjacent the edges of the section b. Section I) may then be removed without disturbing the relation of the other elements, since the section aa which rests on the top of the elbow section 2 and the section a now carries the weight of all of the sections'which lie above the removed section b. V i

The. modified construction illustrated in Fig. ,2 is substantially like that shown in Fig. 1', and similar reference characters have 1 been applied to corresponding parts. The

arrangement shown in Fig. 2 differs from that shown in Fig- 1 mum the several sec- 7,

t-ions constituting the vertical portion of the conduit are provided with lugs 17-17 which are secured together with bolts 18 to 100,

provide a, slightly more rigid structure. The several semi-cylindrical clamping bands 15 in this construction serve merely to hold the grout which is put in place between the opposing ends of the adjacent sections in position. In removing one of the L-shaped sections of this arrangement, it is necessaryonly that the three clamping bands asse ciatedwith that section be removed. The

four bolts,'two on eachfside of the conduit, 7

are then removed and the section taken out of the conduit for repairs or replacement. In the modified arrangement shown in Fig; 3, tl ieseveral pipe sections of which the conduit is formed are made semi-cylindrical and are secured to one another by the sev- 10&

eral clamping bands shown'at 1515. The

elbow -20 affording communication between horizontal'conduit 21 and the vertical cons duit 22 is preferably made of several sec! tions as illustrated, which are clampedor secured together by the lugs and bolts shown at 2323. Grout is interposed between the longitudinal edges 24 and between the opposing ends 25 of the several sections, as

the case in the structure shown in Fig.1. In this construction the horizontal partl'of or sections which are'identical with those which constitute the vertical conduit. If one of the sections, as for example the secthe conduit is preferably made up of units ing bands It and i are moved to the positions indicated by thedotted lines and securely clamped around the conduit. The

clamping band j is then removed from the conduit and the grout interposed between the section 9 and the adjacent sections removed. The section 9 may then be removed laterally and repaired or replaced by a new section. Similarly, any one or more of the sections constitutlng the horizontal run of the conduit may be removed and replaced.

The arrangement shown in Fig. 4 issimilar to that shown in Fig. 3, except that each of the several semi-cylindrical sections is provided with aplurality oflugs through which the bolts 26 pass for the purpose of attaching the several sections to adjacentsections. The clamping bands 15 in this arrangement serve merely to hold the grout or filler in place between adjacent ends of the pipe sections. In removing one of the semicylindrical pipe sections employed in this construction, the clamping bands 15 associated with the section to be removed are disconnected from the conduit, and the bolts 26 holding that particular section removed. The section may then be removed as shown in this figure. I

In all of the foregoing arrangements the vertically extending conduit comprises a plurality of pipe sections or units which cooperate to form single continuous passageway or conduit, but I may arrange the several sections to form two or more conduits positioned immediately adjacent one another and each serving to support the other. In Figs. 5 and 6 I have shown such an arrangement. In these figures 27 designates the horizontal run of pipe and 28 and 29 are vertical runs which communicate with the horizontal conduit as shown. pivoted at 31 and operated by weighted lever 3:2 is employed for thepurpose' of atfording communication between the horizontal conduit and either one of the vertical conduits 28 and 29.

In this arrangement the several sections which make up the vertical pipe sections 28 and 29 may be either whole sections'as illustrated in these figures, Or semi-cylindrical sections as shown in Figs. 1 to l inclusive.

Each semi-cylindrical section is provided with two ormore lugs 3333, which cooperate with the bolts 3434c for the purpose of locking the several sections of different conduits to one another. If it is found necessary or desirable to remove one" of the sections in this construction, as for example, the section shown at k, thetwo clamping bands fitting over the ends of this section are removed, as are the bolts cooperating with this particular section. The grout interposed between the section I: and the adjacent sections is then removed and.

A gate 30 I the section moved laterall out of the conduit. e

In the use of this construction, the operation of the conveyer system need not'be discontinued during the repair or replacement of any one of the sections forming a part of either one of the vertical conduits 28 and 29. For example, when the section k is removed, the gate 30 is moved to the dotted line position so that it discontinues communication between the horizontal conduit 27 and the vertical conduit 29. A steam nozzle shown opposite the conduit 28 is then put in operation and the conduit 28 employed for transporting the ashes.

From the above description it will be observed that I provide a vertical conduit made up of several sections, the sections being disposed in. two or more vertical rows, the sections of one row being connected with sections of a second row, whereby any section may be removed from any row without the necessity of providing some auxiliary support for holding the sections above that removed. The several arrangements shown in the accompanying drawings are self-supporting, and continue to be so even though any one of the sections forming part of the vertical conduit is removed.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. A self-supporting vertical conduit for ash conveyers comprising a plurality of sections arranged in two vertical rows and means for connecting the sections of different rows whereby a section of one of said rows may be removed.
