STEAM-BOILER.
SPECIFICATION forming part of Letters Patent No. 463,804, dated November 24, 18.91. v Application filed April 8, 1891. Serial No. 388,114. (No model.)
To all wwm/ t may concern:
Be it known that I, DANIEL P. MCQUEEN, a citizen of the United States, residing in the city and county of Schenectady, and State of New York, have invented certain new and useful Improvements in Steam-Boilers, of which the following is a specification.
Myinvention more especially relates to that class of locomotive-boilers provided with waro ter-tubes in the re-box and horizontal or substantially horizontal fire-tubes in the boilershell.
Its object is to increase the steam-generating surface of the water-tubes without diminishing that of the fire-tubes, which end I attain by certain novel organizations of instruinentalities hereinafter specified. Unless otherwise indicated, the parts are of usual approved construction.
zo The vaccompanying drawings represent so much only of a locomotive-boiler embracing myimprovements as is necessary to illustrate the subject-matter herein claimed.
Figure l represents a vertical central lon 2 5 gitudinal section therethrough. The left-hand portion of Fig. 2 shows an'end view thereof, and the right-hand portion a vertical transverse section on the line 0c of Fig. 1. Fig. 3 represents a section similar to that shown in Fig. l, illustrating a modification ofvmjT invention. Fig. li shows a horizontal section through one of the tubes on an enlarged scale, illustrating its details of construction and connection with the water-legs or front head.
The fire-box A is shown as inclosed by a front head B, a back head C, and side heads or water-legs D, all connected and forming part of the Water-circulation system of the boiler. The front head is provided with the usual fire-door b. Fire-tubes E connect the fire-box and smoke-box F and are inclosed in a shell Gr. A water-box H extends across the rear portion of the fire-box and is connected 4 5 with thel front head by water-tubes I and with the back head by tubes K.' These tubes pass through the heads of the water-boxes, 'and their ends are perforated laterally, so as to communicate freely with the Water-spaces. 5o These openings 1l are shown in Fig. l. The projecting ends of the tubes are closed with screw-caps t, and they may be screwed or exf panded into the openings in the plates of the heads through which they pass. As this organization constitutes a part of the subjectmatter described and claimed in Letters Patent No. 442,080, granted to me December 2, 1890, it is not claimed herein. The drawings show these water-tubes I as curved in a portion of' their length in the arc of a circle of 6o large radius. The object of this is to have them pass through the heads at substantially a right angle, so as to insure tight joints; but they might pass therethrough at a slight angle and the joints be made tight by properlyconstructed sleeves or thimbles.
In Figs. l and 2, which show the preferred form of construction, the tubes pass straight through the front head and are slightly curved, as above mentioned, while their rear 7o ends pass through a water-box inclined backward at such an angle that they pass through it at right angles. This water-box is located in the iire-box in front of the fire-tubes E, which terminate over the back head O and are of the usual length. Products of com` bustion pass from the tire between and over the tubes I into the space I behind the water-box H and enter all the iire-tubes E. By this organization,it will be seen, a large num- 8o ber of water-tubes may beemployed without omitting any of the fire-tubes. The bottom of the water-box H is connected by a series of backwardly and downwardly inclined tubes K-say three or four in number-which extend through the back head and are connected with its water-space by lateral openings, as above mentioned. These pipes not only serve as water-tubes, but also support fire-brick J, which closes the space between 9o i the Water-box H and the back head A, except that a narrow opening 7a may be left to allow dust, &c., to pass to the bottom of the iirebox. As a result of this organization the flame impinges upon the walls of the nre-box and the back water-tubes K, is then deiiected upward among the front water-tubes I over the Water box H, and inally passes out through the nre-tubes E, thus utilizing the heat effectively. Owing to the inclined posiroo tion of the water-tubes the circulation through them would obviously be very active. The
fire-brick J may be removed to permit an attendant to get at the fire-tubes to clean them.
In the organization shown in Fig. 3 the fire-box is made somewhat deeper and the water-tubes correspondingly lengthened. The water-box H is made shallower and wider and directly connected with the back head C, upon which it rests, instead of being connected therewith byinclined tubes. The tirebrick is dispensed with and the front connection E of the fire-tubes is moved back correspondingly. Some of the tubes I are omitted to accommodate a man-hole H; but the man-hole may be located as shown in dotted lines, and then no holes need be omitted.
One great advantage incident to my improved organization is that, as the front and back heads and water-boxes are stayed by the tubes themselves passing therethrough, I am enabled to use them much closer together, or, in other words, to use many more of them than is permissible in the ordinary construetion, where the tube's simply connect with the inner walls of these heads, as much 4of the space under this organization is necessarily required for stay-bolts; but so far as part of my invention is concerned stay-bolts may be employed, if desired, and the tubes may terminate at the :inner sheets.
By connecting the water-tubes to a waterbox in front of the fire-tubes the full number of fire-tubes may be employed and a large number of water-tubes may be used in the fire-box without unduly obstructing the draft. Vhen the water-tubes are arranged as shown in Fig, l, with a water-box in front of the back head, the fire-tubes may be of the usual length, and my improvements may be added to boilers of usual construction without material alteration.
I claim as my inventionl. The combination, substantially as hereinbefore set forth, of a fire-box having a front water-head, a smoke-box, a boiler-shell interposed between the tire-box and the smokeboX, horizontal fire-tubes extending through the vertical walls of the hre-box and the smoke-box and directly connecting them, a water-box in front of the fire-tubes and disconnected therefrom, and inclined watertubes connecting the front water-head with the water-box in front of the tire-tubes.
