DISINFECTING DEVICE.

SPECIFICATION forming part of Letters Patent N 0. 471,602, dated March 29, 1892. Application filed September 10, 1891. Serial No.405,329. (No modeLJ- Patented in Canada March 16, 1891, No. 36,148;

To all whom it may concern.-

Be it known that I, NELSON M. DYER, a citizen of the United States,'residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Disinfecting Devices, (for which Letters Patent were granted on the said invention in the Dominion of Canada, No. 36,148,

March 16, 1891;) and I do declare the following to be afnll, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in a device for the dispensation of aromatic disinfectants especially designed for overcoming foul odors and rendering the airof compartments fragrant and pure; and it consists in a certain construction and arrangement ofparts, as hereinafter fully set forth, the essential features of which being pointed out particularly in the claims.

The object of the invention is to provide means for dispensing the liquid disinfectant in such manner as to automatically control the supply thereof, and a further provision whereby the supply may be entirely out ofi when desired. This object is attained by the construction illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of my improved device. Fig. 2 is a central vertical section through Fig. 1. Fig. 3 is a plan View of the device, a portion of the top being broken away, showing construction of parts.

Referring to theletters and figures'of reference, A designates a hollow vertical cylinder that forms the inclosing case of the device, in the base of which is located the cup B.

O designates the vessel that contains the disinfecting solution,which may be any of the well-known compounds. Said vessel is cylindrical in form and is placed within the case A through an opening in the top thereof. The upper end of said vessel is supported in the top portion 1) of said case and forms a complementary top thereto and is provided cease.

with a knob d, by means of which the vessel may be raised or withdrawn.

D designates the neck of the vessel 0, and is provided with the valve a, located therein,

, having a valve-seat c, saidvalve being provided with the stem f, that extends beyond the end of said neck when said valve is on its seat and the opening through said neck is closed.

E designates a wire-gauze or perforated annular screen provided with a Wick or outer covering of bibulous material F, which is secured to said screen and retained in place by the wire loops 6. (Clearly shown in Fig. 2.)

Said screen, with its absorbent covering, is

placed within the cup B in the case A, and is held centrally therein bythe rolled rim h of said cup,which environs said screen,the screen in turn surrounding the neck D of the vessel 0.

To prepare this improved device for operation, the vessel 0 is Withdrawn from the case A and the solution poured therein through the neck D, the valve a dropping from its seat and affording a free opening therethrough. When filled, the vesssl Ois inverted, the weight of the solution therein closing the valve a and preventing the escape of the solution while the vessel is beingplaced within the case A. As the vessel O is placed in said case, the stem f of the valve a will strike the bottom of the pan or cup B and raise said valve from its seat 0, permitting the liquid in said vessel to flow through the neck D into the cup B until the liquid in the cup reaches a level above the vent-opening 0 in the neck, Whereby the supply ofair to the vessel C will be cut off and the flow of liquid therefrom will The lower edge of the bibulous covering F, resting in the solution in the cup B, will absorb said solution and become thoroughly saturated therewith. The greater portion of said wick or covering being exposed to the atmosphere the liquid thereon is readily evaporated and thrown 0% through the openings H in the base and the openings etin the top of the case A, perfuming and purifying the air. When the liquid in the cup has been exhausted by absorption and evaporation, so as to bring its level below the ventopening 0 in the neck of the vessel 0, air will be admitted to said vessehand the liquid will again flow therefrom to replenish that within the cup, until the liquid therein again attains a level of suflicient height to close the vent 0 and stop the flow thereof, whereby the dispensation of the disinfecting solution is automatically controlled,insuringa uniform dispensation'of its volatile exhalations.

In the upper end of the vessel 0, as shown in Fig. 2, is a series of pins 1', that register with a notch '11 (see Fig. 3) in the rim of the top portion 1) of the case A. This arrangement permits the vefi el C to be raised until the first or upper pin'thereon passes through the notch 0), when it is turned and said pin engaged with the rim of the top portion 5 of h ea e her by th mee e th v sse 0 s Supported at eh he ght eheve the'he teih 1 f t 11111 a t p rmit at a rea rfihw of l q is the ef em; f de i ed, Sai ves el may he r i d. ah th ewe pin n d w th the lhh t th t p po ti n s l ke m nn r wh n h h ek D of sai e sel w l 'be 19- p rte l a suf i nt istan abo he hottest of the cup to permit the valve a to fall and close the opening therethrough, as clearly pres nce 0E t w tne ses.-
