ASH-CAN ATTACHMENT.

To all whom it may concern:

Be it known that I, BENJAMIN F. HARD- ING, a citizen of the United States, and residing at Milton, in the county of Norfolk and State of Massachusetts, have invented an Improvement in Ash-Can Attachments, of which the following is a specification.

This invention relates to ash-c1111 attachments, and has for its object to construct an attachment adapted to cover the top of an ash-can having an entrance at the side through which the ashes are passed to the can, and having means to prevent the dust from passing out through said entrance; and also having an exit at the side from which a flue-pipe leads, which is adapted to be swung into position in front of the feeddoor of a furnace or other type of heating apparatus, a large proportion of the dust which rises being drawn through said fluepipe. As the ashes are thrown into the can through the entrance the dust rises over substantially the entire area of the can, and while the flue-pipe is able to carry off a large proportion of the dust yet that which follows up along the side wall of the can, more or less remote from the exit, will pass out of the entrance, unless means are provided to prevent it, and herein lies the essential feature of my invention. Herein said entrance is protected above and below and at one end by inwardly extended shields, and the dust which rises and is directed toward the entrance is caused to strike said shields and is deflected inward or its progress checked. The entrance is arranged with one of its ends close to the exit so that a shield is not required at said end. At the outside of the entrance forwardly extended flanges are or may be provided which extend entirely around it, to thus increase its depth and thereby aid in preventing dust from passing out.

Figure 1 is a side elevation of an ash-can attachment embodying this invention arranged in connection with a portion of a furnace. Fig. 2 is a plan View of the attachment. Fig. 3 is a vertical section 011 line 3-3 Fig. 2, looking toward the right. Fig. A is a vertical section on line 14E Fig. 2, looking toward the entrance. Fig. 5 1s a perspective view of the attachment.

In the drawing 10 represents an ash-can of any suitable construction upon the top Specification of Letters Patent.

Application filed March 25, 1911.

Patented Sept. 5, 1911. Serial No. 616,944.

of which my newly devised attachment is adapted to be placed temporarily while the can is being filled with ashes.

12 represents an upright cylinder, here shown as of lesser diameter than the in ternal diameter of the can, having secured to its outer side near the bottom a horizontal flange 13, adapted to rest on the top of the can, with the lower end of the cylinder extended for a short distance down into the can to thus prevent displacement of the cylinder with respect to the can while resting thereon. Said cylinder 12, as here shown, has a flat top plate 14 by which its upper end is closed. Said cylinder has in its side wall an opening 15 designed to serve as the entrance through which the ashes are passed to the can. Said entrance is of any suitable dimensions, but it is understood that it will be made long enough for the easy entrance of a shovel, and high enough to permit a shovel filled with ashes to be easily passed therethrough. Said cylinder also has in its side wall, near one end of the entrance, an opening 16, adapted to serve as an exit for the dust, and from said exit a flue-pipe 17 leads, which is attached at one end to the cylinder by engaging aflange 18 around the exit, in any usual manner, the opposite end of said flue-pipe being adapted to be swung into position in front and into the feed-door entrance 19 of a furnace 20, or other type of heating apparatus.

As the ashes are passed through the entrance and dumped into the can the dust rises and a large proportion of the dust passes through the exit and flue-pipe to the furnace. The dust which rises close to the back wall of the can has a tendency to strike the top 14 and some of it is thereby directed toward the entrance, and to prevent the same from passing out through the entrance a shield 21 is arranged horizontally across a segment of the cylinder 12, 011 the inside thereof, at the top of the entrance, beginning at one end of the entrance near the exit 16 and extending to a point beyond the other end of the entrance, thus forming a pocket above the entrance, and the dust which rises and which is deflected toward the entrance by the top plate strikes upon said shield and is thereby deflected inward or its progress checked.

To prevent the dust which rises close to under side of said shield and is deflected inward or its progress checked.

To prevent the dust which rises at the side wall of the can opposite the exit 16 and which is directed toward the entrance, from passing out through the entrance an end shield 23, is arranged at that end of the en trance, which is vertically disposed between the two shields 21 and 22 aforesaid, extending inward to the inner edges of said' shields, thus forming a pocket between the several shields and the wall of the cylinder, as shown in Figs. 2 and 4, and the dust which rises and moves toward the entrance strikes said shield and is deflected inward or its progress checked. Thus it will be seen that inwardly extended shields are arranged about three sides of the entrance, and owing to the proximity of the exit 16 to one end of the entrance, an inwardly extended shield at such point is deemed unnecessary.

- On the outside of the cylinder around the entrance forwardly extended flanges are provided, the top flange 24 being arranged in the same plane with the inwardly extended top shield 21; the end flange 25 being arranged in the same plane with the inwardly extended end shield 23 and the end shield 26 at the end of the entrance nearest the exit being arranged in a vertical plane, and the flange 13, serving as the bottom flange in front of the entrance, all of said forwardly extended flanges 24, 25 and 26 terminating at their front edges in the vertical plane of the outer edge of the flange 13. Thus it will be seen that outwardly extended flanges are arranged entirely around the entrance.

The relative position and proximity of the exit and entrance to each other are important in adjusting the attachment on the can, to the greatest convenience of the operator.

The severalparts of the attachment are or may be made of galvanized sheet-iron and secured together by ordinary tinsmans joints or otherwise, so as to be quite inexpensive.

In operation the can is located close to the furnace and the flue-pipe leading from the attachment is swung into position in front of the feed-door and the operator can then easily and quickly remove the ashes from the ash-pit of the heating apparatus with a shovel and throw theminto the can, without being troubled in the least by the dust.

I claim:

The removable ash-can attachment herein described, consisting of a cylinder having means at its lower end to engage the top of the can, and having a closed top, an oblong entrance in its side extendlng from the can engaging means to near the closed top,

an exit in its side near one end of the entrance from which a flue-pipe leads, a horizontal inwardly extended shield at the bottom of the entrance, a horizontal inwardly extended shield at the top of the entrance arranged a short distance below the closed top, and a vertical inwardly extended shield at the side of the entrance opposite the exit, extended from the lower to the upper horizontal shield, said shields deflecting and checking the progress of the dust which moves in a direction toward the entrance.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.

BENJAMIN F. HARDING.
