COAL MOISTENER FOR STOKEBS.
Application. filed June 4,
This invention relates to locomotive stokers and has for its principal object to provide simple apparatus for moistening the coal handled by the stoker and to provide a pressure feed watersystem that will deliver the rate of firing. V I V Further objects and advantages of the invention will become apparent as the disclosure proceeds and the description is read in connection with the accompanying drawings, in which Fig. 1 is a rear elevation of a locomotive equipped according to the invention; c
Fig. 2 is a sectional view on the line 2 2 of Fig. 1;
Fig. 3 is a sectional viewonthe linef3,3
of Fig. 2; j
Fig. 4 is a plan view of a control valve; Fig. 5 is a vertical section of the same;
Figs. 6, 7 and Bare-horizontal sections through the valves showing different positions;
Fig. 9 is a side elevation of the ad acent portions of the tender and the locomotive with the invention applied thereto;
Fig. 10 is a vertical section taken on the line 1010 of Fig. 9;
Fig. 11 is a vertical section taken on the line 11-11 of Fig. 10;
Fig. 12 is a side elevation of adjacent portions of a locomotive and its tender with a modified form of the invention applied to them;
Fig. 13 is a plan view of the tender corresponding to Fig. 12.
The general organization is shownin Figs.
1 and 9, in which 10 indicates the back head I of the locomotive, 11 the deck of, the cab, and
12 the deck of the tender.
The stoker illustrated includes a transfer screw conveyor 13 for bringingthe coal from the tender to the locomotive and a plurality of screw elevators 14'for raising the coal to an elevation suitablefor scattering over the grates (not shown). The conveyors are driven by a relatively small multi-cylinder engine 15, mounted below the deck 11 and equipped with suitable gearing for driving the several conveyors. This gearing includes a shaft 16 extending transversely across the locomotive adjacent to the juncture of thethree screws and equipped adjacent to its end with an eccentric 17 (Fig. 9), cooper- 1926. Serial No. 113.7971
ating with a strap 18- to drive a pump, diagrammatically illustrated, by the piston 19, and a cylinder 20 equipped with an inlet valve 21 and an exhaust valve 22. The inlet valve is connected by a: pipe 23 with the tank carried by the tender. The outlet valve 22.
is connected by a pipe 24 with the valve casmg 25 which, in turn, is connected by pipes 26with the casings of the elevators 14.
The valve casing 25 hasa flange 260: i 3
adapted to be secured to the back head of the "controlled by a valve 35 rotatably mounted 1n the casing and equippedlwith a semi-cylindrical skirt 36 adapted to take the positions shown in Figs. 6, 7 and 8, and a variety of positions between those, by which the flow through the several pipes may be controlled and varied to suit the requirements. The valve 35 has a stem37 fixed to a collar 38 by a nut 39 and a key 40. The collar carries a pivoted hand lever 41 having a,
pawl 42 adapted toengage a rack 43 to hold the valve in a selected position. A spring plunger 44 serves to hold the pawl in engagement with the rack. When the valve is in the position shown in Fig. 6, water is freely and equally admitted to both the pipes 26.
'When it is in the position shown in Fig.7,
water is admitted to one pipe only, and when it is in the position shown in Fig. 8 water is admitted to the other pipe only.
The pipes 26 are connected with thecasings of the elevators 14 through jackets 45,
which provide elongated passages 46 extend- 1ing upwardly from openings 47 in the walls moisture to the fuel while {it is passing through the transfer conveyor. This may be accomplished by connecting the pipe 24 with the pipe/49 (Fig; 9) leading to a spray 50, lying over a slot 51 in the casing 52 of the transfer conveyor 13.
A suitable valve 53 at the juncture" of the pipes 24 and 49 will permit the Water to be sent to its transfer conveyor only, or the elevators only, or part to each, as may be desired. r
In the modified form shown in Figs. 12 and13, thepump 54 delivers to a pipe 55 which branches at 56 and delivers to a. plurality of sprays 57, arranged along the up per margins of the coalbirr on the tender.
As here shown, the sprays are arranged along the sides 58 of the bin and just back of tool boxes, 59. Ordinarily it would be objectionable to obstruct the bin from the front, because when the coal boards 60 are removed the fireman should be able to freely enter the bin.
1 claim as my invention: 7
The combination of a locomotive, a:
tender, stoking mechanism for firing the locomotive with fuel carried by the tender, an engine for driving the stokmg mechanism ancl means' driven by said engine for moisteningfuel uniformly as it is supplied by the stoking mechanism.
2. The combination of a: locomotive, tender, stoking mechanism for firing the 10- ,comotive with fuel carried by the tender, an
engine for driving the stoking mechanism and located atone side of the locomotive below the deck, a pump at the opposite side of the locomotive from the engine, transmissionmeehanisrn connecting the engine and the pump and means connected with the 7 pump for moistening the coal.
3. The combination ot a locomotive, a tender having a bin for coal and atank .t'on
-water, stoking mechanism including a conveyor for coal, an engine driving the conveyor, and apnmp driven by the engine for Suppl ing water to the coal.
4. 'l' he combination of a locomotive, a
tender having a bin for coal and a tank for water, stoking mechanism including a conveyor for coal, an" engine driving the conveyor, a spray for the bin, and a pump driving mechanism for supplying fuel to said locomotive, and means for automatically supplying moisture in liquid form to said fuel in proportion to the amount of fuel supplied to said 1ocomotive. y
In testimony wheteofI affix my signature hereto.
