FREDERICK M. OOLSTON, OF BALTIMORE, MARYLAND.

DUST-RECEIVER FOR PIPES OF FLOOR-REGISTERS.

SPECIFICATION forming part of Letters Patent No. 358,733, dated March 1, 1887.

Application filed March 31, 1866. Serial No. 1972;. (No model.)

To aZZ whom it may concern.-

Be it known that I, FREDERICK M. COLSTON, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Dust- Receivers for Pipes of Floor Registers, of which the following is a specification.

My invention relates toa receptacle for dust as applied to and combined with the hot-air pipe leading to registers located in the floor; and the invention consists in the construction and arrangement of parts, as will be hereinafter described, and particularly pointed out in the claim.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a top view of a hot-air register fixed in a floor, being one of the kind to which my improvement is applicable. Fig. 2 is a vertical section of the register seen in Fig.

' 1, and a side view of a hot-air pipe leading thereto, and shows the new dust-receptacle.

Fig. 3 is a side view of the dust-receptacle, and shows a modification in the form of the door through which the dust may be removed.

, Fig. 4 is a horizontal section taken on the line x m, Fig. 3.

The letter A designates the. floor; B, the register; O, the stone usually interposed between the wood fioor and register, and d d the hotair pipe which leads from the furnace to the register. These parts are of the usual or wellplies air to the room will therefore be kept U clean, which is auinoportant desideratum.

Provision is made by means of a door in the receptacle for the removal therefrom of anything that may find lodgment therein.

In Fig. 2 the doorf is in the side of the pipe above the receptacle-bottom g. In Figs. 3 and 4 the door It constitutes also a sliding bottom. By drawing this bottom from its slide 13 the contents of the receptacle will drop out.

Having described inyinvention, I claim and desire to secure by Letters Patent of the United States The combinatiomwith the floor-register and the hot-air-supply pipe, of the pendent hotair pipe communicating by a lateral opening with the supply-pipe and extending below the same, and constructed with a closed bottom and door for the removal of accumulations therein, as set forth.

In testimony whereof I aflix my signature in the presence of two witnesses.

I FREDERICK M. COLSTON.
