- Application filed Getober 580, 1919. Serial No. Toull w/tma it may concern:
Be it known'that- I, Lomsn A. GRIFFIN, a citizen of the United States, and resident of Evanston, in the county'of Cool; and State of Illinois, have'inventcd a certain new and useful In'iproven'ient in Elbows for Ash Conveyor Systems, of which the following is a :tull, clear, and concise description, reference being had to the accompanying drawings, forming a part of this specification.
My invention relates to ash conveyors of the conduit type wherein the ash is conveyed through the conduit by the action of a fluid, such as steam, compressed air or water, and has for its genera; object the provision of im )roved means for facilitation the renewal of those portions of the conduit which, during the operation of the conveyer system are subjected to the abrasive action of the ashes.
In the-installation of conveyor systems of this class, it is necessary, in most "uses, to
provide both horizontal and vertical pipe lines with the result that elbows, or at any rate, more or less abrupt bends or turns must be employed between the pipe lines extending in dili'erent directions. The presence of: these elbows or abrupt turns is,-ot course, accompanim'l by a very greatdegree of wear, due to theabrasivc action of the ashes at the point where the direction of flow thereof is abruptly changed. Because of the excessive wear. on the elbow, it has been the practice to provide elbows comprising renim'able wear liners or; backs which are subject to many objectionsamong which. are, high cost of manufacture and upkeep.
It is the general object or the present l1l-' vcntion to provide a sectional elbow ot' the class described, in which thosev sections subjccted to the greatest wearmay bc ,asily and quickly removed and rcnmved.
These. and other objects ot-the present invention will be pointed out. in detail in connection with the accompanying drawingsp whcrein i igurc' 1 is aside elevationai View show ing' portions of horizontal. and vertical pipe lines and the scctionai elbow of my invcrn tion zliording communi ation l ween "the pipe iincs; I
l1" 2 is an eulari ii cross-scct1onat view of t motored elot v shown in i 1;
3 is a view sirniiar to i showing;
the scmi-cyiindrical throat section of the elbow removed from the co'nveyer system,
and i I Fig. 4 is a view similar to Fig. 2 showing a modified arrangement of the elbow.
' Similar characters of reference refer to similar parts tl'iroughout the several vieWs. Referring, first, to Fig. 1,5 designates a horizontal run of pipe and 6 a vertical run.
7 designates the improved elbow of my in- 'vention which is preferably made up of the how is caused by the injection of steam in the direction indicated. The steam nozzle employed for in ecting the steam may be locat-ed at any desirable point in the conveyer system, and I have not considered it necessary, theretore, to show the steam nozzle. If desired, the steam. nozzle ma project upwardly into the elbow Y between the sections 0 and e. i I
In the preferred form of the invention, the conduits 5 and 6 are made up of several sen'ii-cylindri:al sectiors as shown, each of which is provided with the end flanges 9-9 and slide flanges 10-10 adapted for coi'i-poration will similar flanges 0' adjacent sec tions for the purpose of providing tight l r JOE? between the several sections. the
several sections may be sccureiy locked toauthor by a pluraiity of bolts, as shown, or
may be securral to a c pport as disclosed and claimed in my co-pendin a 'iplication ticrial No. iiii'hifii, filed July 11th, i919.
Referring now to Fig. 2 wh h shows the (retailed construction of the ii'i'iprovod elbow of my invention, the outlet end or conduit of the elbow is formed by two cooperating semi-cylindrical sections as and. 1), each of which is wovid d with the end flanges shown 8* d for cooperation with simiiar images or ad acent sections. The senii-cylindricai throat section 0: cooperates I 01-- no with the angular semi-cylindrical section (Z to provide the inner half of the elbow. The outer half of the elbow is formed by semicylindrical sections 22 and e and the end section c, which as is most clearly shown in this figure, is disposed at right angles to the intake opening of the elbow. Due to the excessive abrasive action of the ashes on the end section a, it is desirable that this section be reinforced or slightly thicker than the remaining sections, as clearly shown in the drawings. I have found that the inner throat section a of the outlet end of the elbow is subjected to excessive abrasive action of the ashes, due probably to the fact that when the ashes strike against the end section c, they are caused to rebound diagonally across the elbow and strike against that portion of the conduit formed by section a. For this reason, the section a is made considerably thicker than the ren'iaining sections, as illustrated. To permit easy and quick removal of the section a, which, due to the abrasive action above referred to requires renewal frequently, I provide the in clined end face shown at 11, adapted for cooperation with a similar "face provided on the upper end of the section (Z. rangement prevents any binding between the sections when the section a is to be renamed. To seal the several joints formed between the conduit sections, the joints are filled with grout made up of a fibrous and cementitious fireproof composition, which may be of the kind and class described in patent to James A. Daviess, No. 1,278,869. If desired, the end flanges 9 9 of the sections may be grooved or serrated, as shown, for the purpose of holding the grout in .place between the sections.
In the modified arrangement shown in Fig. 4, the elbow is made of one piece, except for the inner wall of the throat of the elbow forming the outlet conduit, which is formed by a semi-cylindrical section m, similar in all respects to the corresponding section 0, shown in Fig. 2. In this modification, I have shown the horizontal and vertical runs of pipe 5' and 6' made up oi whole sections as distinguished from the semicylindrical sections shown in Fig. 1.
From the above it will be observed that any section of the elbow may be removed and renewed very easily and quickly and that the removal of any section forming partoi the elbow does'not affect proper support of the vertical pipe. Fig. 3 shows the section a removed and the weight of the vertical pipe 6 sustained by the sections 7) and 0. It the section b or 0 is removed. the weight of This an i the vertical pipe is carried by the sections a, (Z and e.
, Having thus described my invention, what I claim as new and desire to ecure by Letteis Patent of the United States is 1. An elbow for ash. conveyor systems com prising a pair of semi-cylindrical sections forming an intake conduit for the elbow, a pair of semi-cylindrical sections forming an outlet conduit for the elbow, a semicylindrical section forming the outer wall of the elbow, and detachable means for locking the several sections, whereby any one of said sections ma) be removed and replaced.
2. An elbow for ash conveyer systems comprising a pair oi semi-cylindrical sections cooperating to form an outlet conduit, an angular semi-cylindrical section eo-exten'sive. with one of said first mentioned sections, a semi-cylindrical section cooperating with the angular setioll to provide an inlet conduit, an end section extending at right angles to the inlet conduit and detachable meansfor locking the seve *al sections in position, whereby any of said sections may be removed.
A sectional elbow for ash conveyer systems comprising an angular semi-cylindrical section forming the inner half of the elbow, a plurality oi? semi-cylindrical sections forming the outer half of the elbow, and means. for holding the several sections in position.
i. A sectional elbow -tor ash conveyer systems comprising an angular semi-cylindrical section forming the inner half of the elbow, a semi-cylindrical section cooperating with the angular section to provide an inlet conduit. an end section extending at right an gles to the inlet conduit. and means for lock ing the several sections in position.
5. An elbow lor ash conveyer systems ineluding a removablescini-cylindrical section forming the inner half: of theelbow outlet and having end tlanges adapted for cooper: ation with flanges of adjacent sections'td provide tight joints between the sections.
6. [in elbow for ash conveyor systems in:
eluding a. rem vable seinimyliiidridtl section forming the inner half of the elbow outlet,
said section having end flanges adapted tor cooperation with flanges of adjacent sectimis to provide tight joints between the sections and having an oblique end face tacilitating removal of said section.
ln witness whereof. I hereunto subscribe my name this 13th day of Septen'iber, 1919.
