IMPROVEMENT IN LCOMOTIVE ASH-PAN'.

The Schedule referred to in thase'Lettcrs Patent and making part. of the same.

Hon-

To all whomIl tmc- 1f concern Be it known. that I, HENRY A. STonDAnn, of Springfield, in the county of Hampden and State of Massachusetts, have invented a new and useful Improved` Locomotive Ash-Pan; and I do hereby declare that thefollowing is a full, clear, and exact description thereof', reference being had to the accompanying drawing making part of this specification, and to the letters of' reference marked thereon, in' which'- Figure l is a plan view of my invention.

Figure 2 is a side view of the same.

Figure 3 is avertie-al longitudinal section through -line F G of tig. -1.

Figure 4 is an end view, showing thc back damper partially closed.

Figure 5 isan end view, showing the front damper partially closed.

Figure 6 is an end view, showing both dampers open:

' My'inveution relates to the device usually attached to locomotives beneath the lire-box, for the purpose of serving as a receptacle for the ashes which fall through the grate of the lire-box, and which is also a ranged to regulate the draught of air to the tire and It consists of a box closed at the bottom and sides.

A short distance above the bottom is a partit-ion extending parallel with the bottom, entirely across the whole width of the box, and extending longitudinally from one end nearly to the other end.

Above this partition the box is closed upon the two sides and at one end, leaving a space at the rear end of nthe partition, so that'the spaces above and beneath the said partition may communicate.

A small damper is pivoted at one end of the box, which, when raised, allows Athe air to pass into the space beneath the partition, and a larger damper,

pivotedfat the other end ot' the box, when raised, allows the air to pass into the space both above and below the partition.

Small draught-holes may be made inthe largerdamper to allow the air to pass in from behind, assisting 'in and giving direction to the air which passes through the space beneath the partition, as it comes from the other end of the box, and passes to the iire.`

That others skilled in the art may be able to make and use my invention, I will proceed to describe its construction and mode of operation.

In the drawing- B represents a frame, which may be attached to the tire-box ot" a locmnotive, to which frame are attached the perpendicular sides A A.

To the lower edge ot' these is secured the bottom E, and a short distance above the bottom E is secured the partition C, which extends entirely across tire length of the box,

the whole width of the box, and is ,attached to the two sides A A. Y

This partition C extends out flush with one end of the box, and this end, above the partition, is closed by the piece l I Below the partition the piece is pivoted at. a a, so that this piece f may swing outward and upward, as shown .hy the dotted lines in fig. 3.

This lpart C does not extend longitudinally the enbut stops short of it, leaving a space between the end ot' said partition-and the back damper D, which is pivoted to the sides a a at c c, so that said damper may be swung outward and upward, as shown iu dotted lines in g. 3.

An iron, i, may be attached to the back damper D, by means of' which to operate it, and also to the front damper j, as shown at el, for the same purpose.

' The whole may be secured to the locomotive, bcneath the fire-box, by means of bolts passing through the frame B, or in any other convenient or -desirable manner. l

Small holes, h, may be made in the damper D, to

allow the inward passage of air, if desirable. Having thus described the construction of my ii1- vention, will now proceed to describe the mode 'ot' its operation.-

. The device is secured to the locomotive with the endhaving the small damper f forward, and, when it is desired to have a draught of' air pass into the fire, the smal-l damper f is raised. The air is then free to pass in at the opening, as indicated bythe arrow in iig. 3, passing along beneath the partition zC to the rear ol the same, and thence upward to the fire.

The inclined position ot' the back damper D, when shut, tends to give direction to the air in its passage forward and upward to the re.

It'the two holes h are made in the back damper D, the air, passing in through the same, tends to drive the air, which passes in at the forward end and beneath the partition, still fultl1e1 1\vard, when it Areaches the space above the said partit-ion, causing it to be more equally and generally distributed over the' whole surface of the re.

The same elfectmight be produced hy attaching a cmved sheet of metal to the' inside of the back damper D The amount of air passing in at either or both ends may be regulated to any desired degree, by opening or closing either or both of the said dampers f and D.

Itwill be seen that the partition O, being immedin ately beneath the re, becomes very much heated, so that the cold air admitted through the'opening at j becomes in a measure heated as it passes along 'oeneath the partition C, so that, when it comes in contact with the tire, it does not chill the lire.

It will be perceived that in this device the ash-pan is fire-proof, as all the cinders and coal which may Having thus described my invention,

drop through the grate nre enughtby nud remain np- What I elniin as new, and desire to secure by Leton the partition C,amdeannot1mss ont of' the :rsh-pun ters Patent, is

to the. ground without being removed thereli'om,so A loeon'iotive ash-pun, haring the horizontal purthat all danger of tire by eonls dropping ont of the tition G therein, and the dmnpers f and D, all connsh-pzi-n upon Jthe timbers or floors ot' bridges or plntstrneted :ind operating substantially as described.
