IMPROVEMENT IN. SPARK-ARRESTERS.
To 'all whom it may' concern.
'Be it known that we, JACOB WEIDMAN, JOHN MAJOR, and J oH-N J. SAMPLE, of Pittsburg, in the county of Allegheny and State' of' Pennsylvania,
haveinvented a new and useful Improvement in Double-Conc Spark-Arrester; and we do hereby declare the following to be a full, clear, aud exact dcseription thereof', reference being h'adto' the accompanying drawing making a part ot' this specification, in whichy Figure 1 represents a 'front' elevation of the `open smoke-chamber of a locomotive-boiler.
Figure 2 is a y'irtical-eross-section thereof', through the axial line of the smoke-pipe.

Our improvement relates to the construction and combination of devices Yfor preventing the discharge from locomotive smoke --stacks of live V.or burning sparks. The force of the draught, under the ellect of the exhaust, it is Well known, often carries out from 'the smoke-stack burning sparksv of lire,.which, alighting' on somecombustible object, are frequently a cause of great loss.
To enable others skilled in the art to make and use our improvement, we will proceed to describe itsv construction and mode ot operation.A
In the drawing!- a represents the flue sheet 11,'the cylindrical inclosu're of the smoke-chamber; and l c c, the'steam exhaust-lines, all of the usual or any known construction.
Around the base of the exhaust-dues c c we arrange an inverted, inely perforated cene, l, somewhat like the perforated frame ol` an ordinary carbon oil lamplburner;
' From at or near the upper end 0r base of this inverted cone we commence the imperforate smokepipe i, which extends upto a similar nely perferated inverted cone, c', the base of which latter is fastened to the part b just under the stack-opening li',
Outside the pipe i, and at a little distance from it, is a draught-pipe, t', the lower end of which' is funnelshaped, as at fi, and comes down over the joint of the pipe e' and perforated cone c, coming nearly down to the lower end of the cone.
rBhe upper end of it extends up nearly to the upper cone c.
The operation of the devices described is then as follows:
of reference indicate like part-s in The steam, escaping with great force alternately from the exhaust-1iues c c, creates a strong draught through the boiler-fines from the fire-box.
' lhc direction of the force thus exerted causes. the
fsmoke to enter thepipe t through the perforations ot' the cone c, and pass up audout at `thestack.
The sparks of lire which' are drawn through the boiler-fines are thus drawn against the outer face of the cone c, but, on account of the ueness of the perforations in't-he' cone, they cannot pass through itl The draught of smoke'andl steam up the pipev i, and from the smoke-chamber through thenpper cone.A c', causes a strong draught up the chamber s between the pipes 'fi and t.
This carries the sparks up the chambers against the' outer face ofthe upper cone c', from which they are thrown oli` outwardly, to be again carried info the line ofthe draught, carried against the lower cone c, up the chamber s, against the cone c', and so on continuously until they not only become. cold, but, valso,'are sobroken up that they will pass through the perforations ofthe conesl'andl `be carried oi as tine dust.v
.By the use of the centralpipe of a moderate diameter, and extending through the greater part of the height of the smoke-chamber, we secure a powerful draught, and by the use of the doublefcone arrangement, as set forth, we combine therewith an effective spark-arrester, which will not only prevent the escape of burning sparks, but breaks them up and throws them oli` when ucold.
XVe also rind that by the use of these devices we are enabled to enlarge the discharging apertures oi' 'the exhaust-pipes c c. v
'1f these apertures are made small they produce a quick sharp draught, which tears up the fire and draws it through the nues.
Our improvement, by concentrating the force of the draught in the pipe fi', enables us to make the exhaust-pipes c larger, and thereby secure an equally powerful but more uniiblnily-acting draught.
'lhe lire is drawn through less rapidly and a large amount of fuel is accordingly saved.
' XVhat we claim as our invention, and desire to secure by Letters latent, is-
1. The imperlbratedouble-pipes t' i', arranged. in and extending through the greater part of the height ot a locomotive smoke-chamber, the inner 011e being of a uniform, or nearly uniform, diameter, through the greater part et' its length, and the chamber s between the pipes i c", opening atlooth ends into the smoke-chamber, substantially as (lescribed.,
2. The perforated cones e e', one in the upper part MAN, J ORN MAJOR, and JOHN J. SAMPLE, here and the other in the lower pmt of a, locomotive smokehereunto set our hands.
