UNITED STATES Patented February 23, I904.



SPECIFICATION forming part of Letters Patent No. 752,695, dated February 23, 1.904.

Application filed July 5, 1901.

To all whom it may concern:

Be it known that I, FRANK AUSTIN MARTIN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Disinfectant Devices, of which the following is a full, clear, and exact specification. I

My invention relates to that class of disinfectant devices designed to hold a quantity of liquid disinfectant and to feed or drip the same with the desired degree of rapidity into the place where the disinfectant isrequired; and my invention has for its primary object to pro vide an apparatus of this character which shall be of improved, simple, and eificient form and construction and one in which the liquid will be fed therefrom by means of a wick directly into the place where required or into a tube or duct for conducting it to such place.

Another object of my invention is to provide the device with an improved deodorizer for the purpose of disguising the odor of the disinfectant.

Another object of my invention is to provide the device with an improved form of support, whereby the tank may be readily inverted at such times as it may be desired to discontinue the operation of the apparatus or to fill it.

With these ends in view my invention consists in certain features of novelty in the construction, combination, and arrangement of parts by which the said objects and certain other objects hereinafter appearing are attained, all as fully described with reference to the accompanying drawings, and more particularly pointed out in the claims.

In the said drawings, Figure 1 is a vertical sectional view of my improved apparatus, showing it applied to a wall. Fig. 2 is a transverse section thereof, taken on the line 2 2, Fig. 1. Fig. 3 is a detail sectional view of a part of the support, taken on theline 3 3, Fig. 1. Fig. 4:118 a vertical sectional view of the support, showing a part of the wall and a part of the tank, illustrating a certain modification hereinafter described; and Fig. 5 is a similar view illustrating a still further modification of the support.

1 is a tank or reservoir, consisting of a cy- Serial No. 67,144. (No model.)

ameter than the shell and secured in its lower end by means of an annular end piece 7, constituting the bottom of a trough or channel 8, between the wall of the shell and the ring 6.

The bottompiece 4 is formed with a downwardly-extending neck 9, and the upper side of the cap 5 is provided with a cup 10 of larger diameter than the neck 9 and into which the latter dips, as clearly shown in Fig. 1, so that when the tank is filled and held in the position shown in Fig. l the lower end of the neck 9 will be sealed by the liquid in the cup 10, and as a consequence more liquid cannot escape from the tank until the amount in the cup is reduced below the level of the lower end of the neck 9, the escape of the liquidbeing permitted to take place only so fast as the air can enter through the lower end of the neck 9, and consequently the' discharge into the cup will cease as soon as the level in the cup seals the neck.

The side of the cup 10 is provided with a duct or passage 11, extending upwardly from itsbottom and communicating with the lower part of the cup through an opening12 in the side thereof, and through this opening passes a wick 13, which extends upwardly through the tubell and thence downwardly into the annular trough 8, which is supplied with the disinfectant by the capillary attraction of the wick. The level in the cup 10 .being always uniform the feeding of the liquid to the trough 8 will likewise be uniform at all times, regardless of the height of the column of liquid in the tank.

From the annular chamber 8 theliquid escapes, drop by drop or as fast as it isfed by the wick 13, through a drip-tube-l i, depending from the end piece 7, and, as shown in Fig. 1, the end of this drip-tube is inserted normally in the upper enlarged end of a pipe or duct 15, which conducts the disinfectant to the place desired, or, if desired, the tube 14 might of course drip directly into the place where the disinfectant is to be used.

To one side of the shell or tank 1 is secured a bracket-piece 16, which is provided with a keyhole-slot 17 whereby the bracket-piece may be first inserted over a head 18 on a pivot 20, supported by a companion bracket-piece 21 on the wall 22 or other suitable support and then slipped down into the position shown in Figs. 1 and 3, whereby the tank will be securely supported against downward movement and will be held against rotary movement on the pivot 20 by means of the driptube 1 1 and pipe 15. When it is desired to refill the tank or to hold the apparatus out of action, it, is simply necessary to lift it until the tube 1 1 disengages from pipe 15 and then invert it, whereupon it may be refilled by rewardly through the bottom piece 7, the member 4, and the head 2, and this tube also serves as a means for supplying air to the chamber 3, the tube being perforated at 27 just below the bottom 4.

In the form of the support shown in Fig. 4 one of the membersthe member 21is provided with a boss 28 and the other member, 16, with a socket or indentation 29, into which the boss 28 springs when the tank is turned in its upright operative position. With this form the assistance of the pipe 15 in cooperating with the tube 14 for holding the device upright will be unnecessary.

In the form shown in Fig. 5 the back of the tank is provided with two sockets 3O 31, into the former of which engages a hook 32, formed on the lower end of a wall-bracket piece 33, and into the upper one of which engages a straight portion 34:, projecting from the upper end of the bracket 33 and provided with a spring-catch formed on a tongue 35, struck up from the end 34 and serving to engage over the socket 31 when the tank is put in place on the wall-bracket. When it is desired to invert the tank with the form of support shown in Fig. 5, it is simply necessary to lift it off the wall-bracket 33 and invert it, so that the socket-piece 31 32 will change places on the bracket.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-' 1. In a device for the purpose described the combination of an invertible tank for holding a liquid disinfectant having a depending neck on the bottom thereof, a cup conforming closely to and receiving said neck for sealing the lower end thereof, a wick depending into said cup at one end and having the other end extending down the outer side of the cup and a removable cap for holding said cup, substantially as set forth.

2. In 'a device for the purpose described the combination of a tank having an air-chamber at the bottom thereof, and a neck depending into said air-chamber, a removable cup fitted in the bottom of said air-chamber and receiving said neck, a wick dipping into said cup at one end and depending over the edge of said cup into said air-chamber at the other end, a

drip-tube leading from the bottom of said air-chamber and an air-tube extending upwardly into said air-chamber, substantially as set forth.

3. In a device for the purpose described the combination of a tank for a disinfectant having a perforated or foraminous chamber on the upper end thereof, an air-chamber in the bottom of said tank, means for feeding the disinfectant into said air-chamber, a tube extending through said air-chamber-and tank and communicating with both of said chambers and an absorbent in said foraminous chamber for containing a perfume, substantially as set forth.

4. In a-device for the purpose described the combination of a shell having the bottom 4t provided with depending neck 9, the annular end piece 7 provided with a threaded flange a cap threaded in said flange, the cup 10 supported on said cap and receiving the lower end of said neck 9, the wick-tube 11 secured to the side of said cup and communicating at its lower end therewith, the wick in said tube and a drip-tube leading from said end piece 7, substantially as set forth.
