FOR LOCOMOTIVES.

Application filed March 18, 1915', Serial No. 15,157. Renewed August 18, 1917. Serial No. 186,'9 18.

To allwhom it may concern:

Bait, known that we, ELDIA J. CARTER, ALBERT TAYLOR, and JAMES S. GRIFFITH, citizens of the United States, residing at Mbbridge, in the county of Walworth and.

State of South Dakota, have invented certain new and useful Improvements in Spark- Arresters for Locomotives; and we do hereby'decla-re the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to locomotives and 16 has for its object to provide an improved spark arresteror destroyer therefor; and, generally stated, the invention consists of the noveldevices and combinations of dethe claims. a

-It is, of course, a well known fact that.

vices'herein'after described and defined ing way by sparks emitted from the smoke stacks of locomotives. Various spark arcollecting the sparks within the smoke box' of the locomotive but such devices have hitherto been inefiicient to stop all' of the sparks or have been subject to a serious de feet, that they 1. would interfere with the draft of the locomotive. -Ourinvention provides a spark-arrester which does not interfere with the draft of the locomotive andthe chief function. of which is to break up theredhot sparks lnto suchfine form that they will almost instantly, either burn entirely up, or be. cooled arid extinguished, so that they will not start fires after they have been deposited along the right-o'f-way.

'Theinvention, in its preferred form, 18 illustrated in the accompanying drawings wherein like characters indicate like parts throu houtthe several views. I

erring to the drawings:

Fig. 4 is a transverse vertical section taken on the line .90 m on Fig. 1;

Fig. 5 is a horizontal section taken on the line 92 v on Fig. 1; and

Fig. 6 is a horizontal section taken on the line w m on Fig. 1 looking upward.

Of the parts of the locomotive, the nu meral 1 indicates the boiler, the numeral 2 the smoke box, the numeral 3 the fines, the numeral 4: the steam pipe, the numeral 5 the exhaust nozzle or exhaust nozzle stand, the numeral 6 the smoke stack and the numeral 7 the deflecting plate, all ofwhich parts are of standard or well known construction;

In the application of our invention, the lower section 6' of the smoke stack is made or provided with a downwardly flaring conical lower end portion 6*, and a conical plate nor center cone 8 is suitably secured in a poma'ny firesare started along the right-o sition concentric to the said flaring end 6*,

5, being,

which the exhaust from the said nozzle may freely pass upward. As shown, the said cone 8 is attached to the nozzle by means of small angle brackets 9 and cooperating rivets or bolts, and preferably, the said cone is made up of several overlapped segments, which, at their outer edge portions aresecured'together with freedom for circumferential expansion and contraction, by means of bolt and slotconnections 10..- The outer of the said bolts 10 are relativelylong and reach 'fromthe sectional cone 8 tothe conical lower end .6 of the stack, and are anchored to the said part 6 so that they assist in properly spacing-the said parts'8 and 6 The said cone 8 and conical lower end 6 of the stack are thus spaced apart, so that they afiord a'converging annular or conical smokepassage .11; The numeral 12 indicatesso-called strikin qpins which are preferablyof -iron. or stee and rectangular in cross=section, and provided, each, at one -:and is preferably secured directly to the upper end of the exhaust nozzle 25 resters have been provided for stopping org i iof course, provided with a passage through end, with. a-reduced threaded. trunnion v13 ion the interior of the stack section 6,, to its flaring lower end portion 6 and. to the cone or conical plate 8. Their trunnions13 are passcd through perforations in the said parts to which theam applied with the washers 14 and 15 clamping the said parts to which they are applied, when the sai nuts 16 are tightened. It will be noted hat the said striking .pins are set so that they incline slightly'downwardaiitlradiate in ii'esp'ect to the axis of the stack. Here itshould be noted that the striking pins 12 that are within. the stack-section 6' terminate short of the axis of the stack far enough to leave an unobstructed central or axial-passage 'for the exhaust from the exhaustnozzle. The said striking pins of the several vertically spaced horizontal series are staggered in respect to each other, preferably as illustrated in Fig. 2, so that the sparks passing upward between the same will strike in succession against the vertically spaced rows of pins. The striking pins that are applied to the conical portions 6' and 8 are staggered in respect to each other, so that the sparks which are drawn upward into the smoke stack, Will be caused'to strike over and over again against the said pins and will mostly be disintegrated and broken up before they are carried into the stack proper. Thus, those reaching the stack will he further caused to strike against the pins in the lower stack section 6 so that by the time they have passed out ofthe' stack, they will-be puiverized or broken up to such an extent that they will be either burned or cooled so that they will not start fires along the right-0t way. It is well known that when a coal or sparkis violently thrust against a hard surface, it will be split up into such' fine par ticles that fire will be immediately put out, and where this does not happen, that the small broken particles will very quickly cool in passing-through the'air, and'thus their ability-to start fires is destroyed. Some of the broken vsparks or cinders may fall to the bottom of the smoke box, but these, of course, rnay be readily removed.

The numeral 17 indicates washout I pipes which :extend" -fromthe boiler forward, throngh or slightly under. Athedeflecting plate 7, and terminate at their front ends below the flaring lower end of the stack, sothat the discharge therefrom willbe' efl'ective to wash out the smoke box. llhe downwar dinclination of thes-triking pins toward the axis of the stack, ahasfavtendehcy to cause the sparks to be deflected 3 radially Joutward-and to keep :the; same. away frem the device describedis-eificient for '.the purposes had' in view and may: be "readily unobstructed axialeexhaust passage of the at eomparativiely sfnallcost.
