UNITED STATES PATENT OFFICE.

VILLIAM Y. OBER, OF LYNN, MASSACHUSETTS, ASSIGNOR TO THE STANDARD MINING AND VENTILATING COMPANY, OF PORTLAND, MAINE.

VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 409,224, dated August 20, 1889.

Application filed February 8, 1889. Serial No. 299,166. (No model.)

To (tZZ whom it may concern.-

Be it known that I, \VILLIAM Y. OBER, of Lynn, in the county of Essex, State of Massachusetts, have invented a certain new and useful Improvement in Ventilators, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, refer- IO ence being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a sectional view of a building provided with my improvement; and Figs.

r5 2 and 3, enlarged views of a portion of the pipe, illustrating certain details of construction.

Like letters and figures of reference indicate corresponding parts in the different fig- 2o ures of the drawings.

My invention relates to that class. of ventilators which are provided with disinfecting material; and it consists in certain novel features, as hereinafter fully set forth and claimed, the object being to produce a simpler, cheaper, and otherwise more desirable device of this character than is now in ordinary use.

The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation.

In the drawings, A represents the building, and B the rotary power fan or blower.

The blower B is of the ordinary form and construction, and is actuated by an electric dynamo or engine F, being connected therewith by a belt ,2. The blower is preferably situated in the basement of the building A,

0 and is provided with an induction-pipe so,

which passes through the wall I) of the building, and through which fresh air is supplied. An eduction-pipe 41 leads from the blower vertically through the different floors of the 45 building, branch pipes f being connected thereto and running horizontally between the floors (Z and ceilings g thereof. Supplemental branch pipes h tap the pipes f and enter the rooms of the building at any desired point,

said pipes being provided with flaring mouthpieces 1 opening into the rooms in different directions, and with ordinary dampers or valves 70, by means of which they may be readily closed. An opening m is formed in the eduction-pipe o, and a curved plate 1.) is fitted to slide in ways g on said pipe and close said opening. A bag or receptacle D composed of reticulated fabric, preferably wire, cloth, is suspended within the pipe o, opposite the opening m, by means "of a plate t, which rests upon studs w in said pipe, said bag being filled with disinfecting or fumigating material.

In the use of my improvement fresh air is admitted into the blower B through the pipe w, and is forced thereby into the pipe '0, whence it may be readily admitted into the rooms by opening the valves in the branch pipes h. Any suitable disinfectant may be employed in the holder D, and the air being 70 forced through the same by the blower becomes thoroughly impregnated therewith. Fumigating material may also be employed and can be readily lighted in the holder through the opening at, the smoke from the burning material being rapidly carried into the rooms by the current of air in the pipe 1* when the valves 70 are opened.

It will be understood that the holder D can be readily removed through the opening m to be refilled or replaced by another containing fresh material.

Havingthus explained my invention, what I claim is 1. In a ventilator, the combination of a rotary blower provided with an induction-pipe for supplying fresh air thereto, an eductionpipe connecting said blower with different stories of the building, said eduction-pipe being provided with a side opening and with 0 a door for closing said opening, branch pipes leading from the eduction-pipe into the different rooms of the building and provided with mouth-pieces having valves for closing: the same, and a receptacle detaohably disposed in said eduction-pipe opposite said opening, and adapted to contain disinfecting material for impregnating the air as it passes through said pipe, substantially as set for forcing air through said pipe,substant-ially forth. as described.

2. The eduction-pipe v, provided with the T T opening m, door 13, and studs 10, in eombina- W ILLIAM OLER' 5 tion with the reticulated holder 1), adapted Vitnesses:

to contain disinfecting material and provided E. M. SPINNEY, with the plate t, and adjunetive mechanism 0. M. SHAW.
