LE GRAND PARISH, OF NEW YORK, N. Y.
CIRCULATION AND FEED DEVICE FOR- LOCOMOTIVES.
To all whom it may. concern Be it known that I, Ln GRAND PARIsH, a citizen of the United States, residing at New York, county of New York, and State of New York, have invented certain new and useful Improvements in Circulation and Feed Devices for Locomotives, of which the following is a specification.
This invention relates to circulation and feed devices for locomotives and more particularly to an improved arrangement of circulation tubes in a locomotive fire box whereby water from the injector may be introduced into the boiler through the forward end of one or more of the circulation tubes. One of the chief objects of my invention is the provision of novel means whereby the water, as it is being injectedinto the boiler, is immediately subjected to the action of the hot gases in the fire box. Another object resides in the provislon of an improved arrangement of the circulation and feed water connections whereby the nor- -ma1 flow or circulation through the boiler materially assists in the feed operation, particularly when the injector mechanism is first actuated. My invention also contemplates the provision of a delivery member at the discharge ends of the circulation tubes and communicating with two or more thereof, in combination with a. feed water connection at the forward ends of such tubes, whereby when water is being injected into one or more of the tubes, a more rapid flow is induced in the other tubes.
The foregoing, together with such other objects as may hereinafter appear or are incident to my invention, I attain by means of a construction which I have illustrated in preferred form in the accompanying drawings, wherein- J Figure 1 is a longitudinal sectional view showing my improvements applied to a locomotive fire box having a deep throat sheet; Fig. 2 is a cross section through the boiler of Fig. 1; Fig. 3 is a longitudinal sectional view illustrating one form'of the application of my improvements to a standard form of locomotive fire box in which the front water leg is comparatively short; Fig. 4 is a section through the boiler of Fig. 3; and Fig. 5 is a sectional detail illustrating a modification of my invention.
Referring to the drawings, it will be seen that the general construction of the fire boxes is of the. standard type. The fire Specification of Letters Patent.
boxes are composed of an inside fire box, comprising a tube sheet 1, side sheets 2, back sheet 3 and crown sheet 4; and an outside box, comprising a throat sheet 1, side sheet 2, back sheet 3 and cover sheet 4. The water legs are closed by a, mud ring 5. It will be noted, however, that in Figs. 1 and 2 the throat sheet 1 is deeper than in the type shown in Figs. 3 and 4. The tube sheet 1 is carried upwardly to the crown sheet 4 in the usual manner, and the ends of the fiues 6 are expanded therein. The fire boxes are provided with stay bolts, but as these form no part of the present invention, they have not been shown.
Attention is now directed to Figs. 1 and 2. In this construction I provide a plurality of rearwardly and upwardly extending circulation tubes, preferably eight in number, arranged in two rows, 8 and 8. Although these tubes may be secured to the tube sheet 1 and the back sheet 3 in the customary manner, I prefer to extend the ends Patented May 20, 1919. Application filed October 19, 1914. Serial No. 867,299.
and the extremities of the tubes are expanded in the sheets 1 and 3". At the rear or discharge ends of the tubes, I provide four delivery members 10,each one of which is common to two circulation tubes. The discharge ends of the delivery tubes open into the space above the crown sheet, preferably at a point approximately at the normal water line. Communication between the boiler and the forward ends of the circulation tubes is obtained by means of extension members 11 of which I prefer to provide one for each tube to more readily compensate for the expansion of the throat sheet. The rear end of each of these members is fastened to the throat sheet over the end of a circulation tube and the forward end of each member extend-s into the boiler space at a point by means of feed water pipes15 whereby may be cleaned by uncoupling the pipes 15.
.One of the chief advantages of the foregoing arrangement of circulation tubes and feed water devices is that the water is in-'.. jected into the forward end of the tubes where it is immediately subje ted to the action of the hottest gases in t e fire box because such ends of the tubes are nearest to the fire bed. The water must also traverse the Whole length of the fire box before, it mingles with the contents of the boiler. and it will be apparent that the temperature of the feed water as it thus passes through the tubes is at once raised to a high point before commingling, the advantages of which will .be clear to those familiar with the art. In
addition the feed water is injected in the line of the normal flow or circulation through the tubes which is of material as sistance, particularly in the beginning of the injection operation.
The coupling of pairs of circulation tubes by common delivery tubes in conjunction with my improved arrangement of feed water device is also advantageous as it will be clear that the increased flowtaking place in the upper tubes when water is being in-' jected therein induces, by entrainment, a
"heavier flow through the lower tubes, thus adding to the efficiency of the fire box.
It will also be seen that greater efli'ciency is obtained because of the fact that the extension members communicate with the boiler at a 1 point removed from the tube sheet 1, adjacent to which steam bubbles or blisters frequently form, owing to its proxrangement of the circulation tubes and feed water connections is modified for adaptation to a standard fire box in which the throat sheet is-notso deep as that shown in Figs. 1 and 2. plished in various ways, but I prefer to bend This adaptation may be accom-.
the middle tubes of the upper row of circulation tubes downward ina, reverse curve adjacent to the'tube' sheet 1, and extendthem through both walls of the forward water leg approximately inline with the tubes of the lower row. A pair of extension members 11 establish communication with the boiler, as previously described. By
"bending the tubes downwardly and. to the side, am enabledfionveniently apply the extension members and forward feed water device to a standard fire box, and am there- The brick arch is not shown in Fig. 1, as
that construction there shown is such that the bricks may be sup orted accessibly and removably on any of-t e tubes, as indicated in my issued Patent No. 1,110,815. In. the
structure of Figs. 3 and 1, the front bricks 17 are of greater length than the usual brick in order that they may be securely supported.
on the tubes.
' It will be seen that I have illustrated my invention in the drawings in simple form and that the arrangement and construction of the parts may be varied without departing from the spirit of my invention.
I claim:
The combination with a locomotive boiler having a fire-box, water spaces, and a-normal circulation tube of substantially uniform flow capacity throughout extending through the fire-box rearwardly and upwardly and connecting water spaces to establish normal circulation of water therebetween, of means for utilizing saidtube as a heater of feed Water comprising a feed. water delivery member communicating wit the tube at the forward end thereof without restricting the same, whereby feed water may be injected into said tube.
In testimony whereof I have hereunto signed my name in the presence of the two subscribed witnesses.
