vaporization of liquid is effected heat, my.
improvements are designed primarily and especially for use in connection with'boilers and t am senera exs oper i u d r P sure in excess of. that of the atmosphere, my object being to afford simple but effective a g means. w ereby eld m ntet may ile t i' ly im d th afety, he
per on ein senti lly autom t c h s pe t. l as h ei after ul y se orth. and the invention 'consisting in .the specific combination and arrangeineht of parts and appurtenances described and clai ned.
n h 'si pe 'y ns dra in s, I emr plify a practical enibodiinent of the essential features. of my invention, although I, do not restrict myself to the identical form and construction ofparts shown, since rnodi fications in ininor details and equivalent mechanical expedients :inay heresorted to with like results, and Without departing from the spirit and intent of my invention.
lVith this understanding: i
Fig. l, represents the side elevation of a steam generator of the vertical 'tube or Scotch boiler. type provided with my sedinient discharge appliance; i q I i Fig. 2, is a'plan, u on a larger scale, 01, theboiler and apparatus shown in Fig. 1;
Fig. 3, is a central vertical sectional elevation of the parts shown in'FigLQ;
Fig, 4, is asectionalelevation of the sedinientdischarge tubing, etc., lookingin the direction of thearroivt Fig. 3, the by pass tubebeing omitted;
Fig. 5,"is a sectional detail on a larger scale, taken upon plane of line Figl't.
The outline a, a, shown in Fig. 1,01 the drawings indicates diagraniatically the installation of my sediment eliminating apparatus in connection with a boiler B, inclosed in the hood H, of an automobile,- al-' though, as hereinbeltore intimated, I do not. li nit'inyselfto this or, any other particular use, nor to a specific type of steain gen erato y that (B) shown being of the Scotch or, vertical kind, provided with the usual upright'flues b, b, for the passage of the products of combustion from a gas coilg, oriother suitable,"means 01 eli'ecting ee aimr t npf he iq i 1, in i o leiw ep eenti g the" approx iiat norma liquidfleveli A pl al ty. of fl id i c epipes d, Z, extend through the headdr, of the boiler B a majority of thein extending down to a co ninon level near the botto n plate Z2 of saidboiler, four of these lower level drain pipes being shown in the drawings, although anydesired number may be provided, P f rably a ra ged in qu i ta t e at o ship around thecentral vertical axis of the pb sene atins hamber- A shorter. discharge pipe 05*, is preferably positioned" centrally as related to the vaporizing chamber and to the aforesaid plurality of lo we'r; level lrain pipes at, d, said central discharge pipes gZ extending down only to a level a little below the normal liquid level Z as show more particu larly in Fig. '3, of the dra ingsJ.v
This higher levehdischarge pipe (5*, is connected by auxiliary piping (W, with the lower end of an expandiblestand pipe 6, on theiu'pp er extremity of which is attached an elboxv'couplin'g e, on which is mounted a push valve rod e which protrudes through a 'stufiingbox 0,0n the'lover portion of the coupling head C, as shown more particularly in Fig. '3, ofthe drarizingab y reference to which'it ivillalso, he seen, that a ball valve 1)., is positioned'on the upper end oif'said push-red e for engagement with, a valve seat 0, located centrally. in said coupling C, saidvalve sgeat c, fornjiing the inlet to the discharge conduit 0 of the coupling headG, vvliich latter communicates throug'l'i' thebranch pipe 7', ,"With the ejector valved, which constitutes the means for 'theiniti al control or my draining app aratus, consid ered' in a unitary sense;
The valve chamber 6*, of the coupling head C, has three inlets; one, 0 connecting With a nip le'a to vvliicli the upper end of a hent by-pass tube 10, is connected; the other 'tWo inlets communicating through nipples cfiqoflevith the ipesd, dgwhi ch connect with the upper ends of the lower level drain pipes (Z, (Z, as shown more particularly in Fig. 2, of the drawings.
The bent by-pass tube. p, is preferably made of copper to afford the requisite degree of flexibility, and its lower extremity is connected with a lateral nipple 0 of the elbow coupling 0, as shown more particularly in Fig. 3, of the drawings.
The elbow coupling 0, is essentially a slida-ble cross head, being formed with rigid. lateral arms 6*, a, through which the guide rods 7*, 1 extend, said guide rods r, 1'", being rigidly secured at their upper extremities to lateral arms 0 0 on the coupling head C, and at their lower extremities to cross arms 23, t, on a head T, which is slid-ably mounted on a sleeve S, rigidly secured to the lower portion of the expansion pipe 6, as shown more particularly in Fig. 5, of the drawings. The upper portion of the sleeve S, is male screw threaded for engagement with the female screw thread of an adjusting nut s, between which and the cross head K, is interposed a take up or compensating spring K, which tends constantly to relieve the guide rods 1', r, of possible distortive strain owing to inequality of expansion as compared with and related to the expansion valve tube The operation of my cleansing apparatus is as follows. When it is desired to eliminate sediment and scum from the boiler B, the ejector valve J, is opened, and as a result the steam pressure in the upper part of the boiler forces the liquid Z, out through the discharge pipes (i, (Z, (V, the sediment being carried out through the lower level pipes (Z, (Z, and the scum through the upper level pipe 6D. The lower level discharge pipes (Z. d, communicate, as hereinbefore set forth, directly with the coupling head C, whereas the upper level discharge pipe d", d comnmnicates indirectly with said coupling head C, through the medium of the expansion stand pipe e, and bypass pipe 79, as clearly indicated in Fig. 3, of the drawings. As a consequence of this arrangement, when the liquid level Z, falls below the lower extremity of the high level discharge pipe (1". live steam will be admitted thereto, and through it and its connection pipes (Z*, to the expansion valve pipe passing off through the by-pass pipe 79, and coupling head Q. As a result of this live steam discharge the pipe 6, will expand, the by-pass pipe 77,
yielding sufiiciently to allow the expansion pipe 6, and push valve rod 6 to close the valve 1), on its seat 0, and thereby automatically stopping the discharge, of both fluids as long as the liquid level Z", in the boiler B, is below the inlet to the high level discharge pipe cl Eiupposing the ejector valve J, to be left open unintentionally or otherwise, and the liquid in the boiler B, to be replenished to normal level, the operation described will be repeated without harm to the apparatus; but the closing of ejector valve J, will of course render the device inoperative for the time being.
If the discharge of live steam through the expansion valve pipe 0, results in the elongation of. said pipe after the valve '0, is in engagement with its seat 0, in the coupling head C, this excess of expansion is compensated for by the spring K, which in such event relieves the guide rods r, 1", of distortive strain as hereinbefore explained.
It will be understood that by thus automatically closing the valve '0, when the liquid level Z, falls below the upper level discharge pipe d, the boiler is protected from damage that might otherwise result from excess of heat in the absence of a suitable volume of liquid therein.
It is to be understood that the steam discharge pipes (Z connecting the upper level pipe cl", with the expansible stand pipe 6, have sufficient give or flexibility to admit of this excess of expansion of the tube 6, if it occurs.
