WILLIAM E. PETERSON, OF SPOKANE, WASHINGTON, ASSIGNOR OF ONE-HALF TO ORINO, OF SPOKANE, WASHINGTON.
SPABK-ARRESTER.
Specification of Letters Patent.
Application filed August 5, 1919. Serial No. 315,378.
To all whom it may concern:
Be it known that I, WVILLIAM E. PETER- soN, a citizen of the United States, residing at Spokane, in Spokane county and State of Washington, have invented certain new and useful Improvements in Spark Arresters, of which the following is a specification.
The present invention relates to improvements in spark arresters for use on railroad locomotives as a preventive of flying sparks from the stack of the engine setting fire to brush or dry veg etable growth alongside the railroad during dry seasons.
The primary object of the invention is the equipment of the locomotive stack with a device orapparatus operative and regulated from the cab of the locomotive and under the control of the engineer, or fireman, whereby the sparks or cinders may be prevented from flying from the stack when desired, and the invention also provides means whereby the arrester device may be withdrawn from operative position to pass under low bridges or run through tunnels. The invention consists in certain novel combinations and arrangements of parts as will be described and claimed hereinafter.
In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention, showing the parts constructed and arranged according to the best mode I have so far clevised for the practical application of the principles of my invention.
Figure 1 is a view in elevation, looking from the cab end of the locomotive, showing the smoke stack equipped with the spark arrester of the present invention.
Fig. 2 is a view in side elevation, on a smaller scale than in Fig. 1, showing the equipment for a locomotive, and indicating the operating mechanism for the device, in the engineers cab.
Fig. 3 is a detail View showing the means for elevating the conical deflector, located within the reticulated screen, as the movable reticulated screen is withdrawn from operative position.
In the preferred formof the invention as illustrated in the drawings I have utilized the smoke stack 1 and the boiler front or smoke box 2 for the purpose of showing the applicability of the invention, and the invention involves an equipment for a locoscoping, cylindrical section 4, fitting neatly within the base, may be projected or retracted with relation to the base, as desired.
At the upper end of the telescoping section, an annular bead or band 5 is fixed, and this is utilized to secure to the section the reticulated screen 6 built upon the frame or skeleton 7, and of the general shape and outline shown in the drawings, the screen being open at bottom and top and having its .sides bowl outwardly as indicated.
The screen and the telescoping section are movable together and may be projected to operative position, or on account of approach to a low bridge, or to a tunnel, when required, they may be retracted, as in Fig. 2, and for this purpose, a pair of diametrically arranged threaded bosses 8, 8 are secured to the screen frame as clearly shown in Fig. 1, and adapted to receive the screw bars 9, 9, arranged vertically, and parallel with the smoke stack, and supported in bearing brackets 10, 10 fixed to the base '3; A system of angularly disposed counter: shafts extending around the front of the stack, with complementary bevel gear wheels, as 11 connect these two screw bars through the instrumentality of the horizontal bevel gears 12 12 at the base of these screw bars and a bevel gear 13 on the shaft 14 is turned through the medium of the hand wheel 15 at the end of this shaft. The shaft extends to the rear of the locomotive and is supported in proper bearings at the top of the boiler casing, while the hand wheel is located within the cab to be accessible to one of the enginemen. Thus by turning the hand wheel, the two screw bars 9, are revolved in unison, and by their threaded connection with the bosses 8 on the reticulated screen they transmit motion to the screen and telescoping section to elevate or depress them, depending upon the manner of revolving the hand wheel.
Within the top of the reticulated screen, a conical shaped deflector 16 is provided, its

position being inverted, and having a hinge Fig. 1, the deflector permits gases, to pass through the screen, but the cinders striking the deflector at any point are turned and deflected in their course, and sent downwardly. against the inner 'face of the. bowled sides of the screen. In their passage along the face of the screen the cinders will scrape off and prevent accumulation of soot, or the closing of the reticulated screens by soot or cinders, and thence the cinders pass down the outside of the stack within the telescoping section and base cylinder.
When the screen and deflector are not necessary, and it is desired to remove the deflector, the purpose is accomplished by re-' tracting the telescoping section and the screen, and in conjunction with an abutting cup or receiver 18 vertically arranged on the crank arm 19 journaled in the vertical bearing 20 fixed to the locomotive stack within the base cylinder 3, and the crank arm is moved by the connecting rod 21 extending back to the lever 22 in the cab of the engine. When not in use, the receiver 18 is swung in its bracket 20 to one side of the stack, but when needed to swing the deflector on its hinged joint, the lever 22 'is operated to swing the cup into the position of Fig. 3 where it is shown in the center of the stack just above its open top, and directly beneath the apex of the inverted, conical deflector. Now when the telescoping section and screen are retracted or lowered, through the bevel gearing and screws, the apex of the cone or conical deflector is supported while the hinged, jointed, part of the deflector is lowered, with the'final result that the deflector is turned back on its hinge joint to the position shown in full lines Fig. 2, the upper horizontal arm of the crank 19 swinging outwardly as the parts telescope and thus following the apex of the deflector. In this manner the spark arrester and the deflector may be controlled and manipulated from the cab, while the train or locomotive is in motion, formoving the device tooperative position to prevent the flying of cinders and sparks, or for retracting the-spark arresting device when approaching a low bridge'or tunnel, and for freeing the device of the deflector when the latter is not required.
What I claim is p I 1. The combination with the fixed base, of the movable screen and operating means therefor, a conical, inverted, deflector hinged in the open top of the screen, and means for removing the deflector as the screen is moved to inoperative position. I
2. The combination with the fixed base, the telescoping sectionyand the open top screen supported on the latter, and means for moving the screen to inoperative-positlon, of an inverted, conlcal deflector hinged 1n the upper open end of the screen, and
means for supporting the apex portion of the deflector while the hinged portion is be ing lowered as the screen is moved to inoperative position, whereby the deflector is removed from operative position.
3. The combination with the fixed base, telescoping section, screen section, hinged, inverted, conical deflector on the screen, of a properly supported crank member having an abutment to support the apex of the deflector while its hinged portion is being lowered, to move the deflector to inoperative position.
In testimony whereof I afiix my signature.
WILLIA E. PETERSON.
