THE COLUMBIA PLANOGRAPH 60.. WASHINGTON, D4 c.
UNITED S PATENTQFFICE- rnoivmsv. MAD I AN, ooma, NEW YORK.
To all whom it may concern: q
Be itknown that I, THOMAS V. MAnIoeN, a citizen of the UnitedS't-ates, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Disinfecting Devices; and I do declare the followingtto be a full, 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.
My invention relates broadly to improvements in disinfecting devices, and more particularly to such an article so constructed as to allow it to be applied as a cover to a garbage can or to analogous forms of refuse containers. A
The object of theinvention is to provide 7 a device of this character which may be very;-
simply and inexpensively constructed and marketed, yet one which will effectively disinfect the contents of the container to which it is applied, thus destroying any obnoxious odors which might. otherwise exude therefrom.
WVith this object in view, the" invention resides'in certain novel features of construction and combination hereinafter more fully described and claimed, and shownin the drawings wherein:
Figure 1 is a side elevation of a garbage can showing the application of the invention thereto; Fig. 2 is an enlarged vertical section through the cover of the arbage can, but showing the means for discharging the disinfecting fluid, in elevation; Fig. 3 is a similar view of the parts seen in Fig. 2 and illustrating the delivery tube in elevation, with the cap thereon in section; Fig. 4 is a view identical with Fig. 3 with the exception that both the delivery tube and cap are shown in section, and Fig. 5 is a detail horizontal section as seen along the plate of the line 55 of Fig. 2.
In this drawing, constituting a part of the application, C designates a garbage pail or can which is shown as provided with the usual arched handle H. Constituting the cover of the can 0, is a device 1 wherein resides the gist of the present invention.
The device 1 comprises a top plate 2 which may be corrugated as shown in the drawing or may be of any desired configuration, the edgeof said plate being provided with a depending annular flange 3 which may fit around the top of the can G as shown in Specification of Letters Patent. Patented Feb. 15,1916.v Application filed February a, 1915. Seria'1 No, 6, 8 19.
the drawing, or maybe received in said top, provided necessary alterations are made. Spaced an appropriate distance below the top plate2, and secured at its edge within the flange 3, is a bottom plate 4, said flange, the plate 4,.a-nd the top platel constituting a receptacle adapted tocontain a; dis
infecting fluid, such receptacle being provided with an inlet normally closed by a from the spirit or sacrificing any of the ad-.
vantages of theinvention.
v 'Depending from a central opening in the bottom plate, is a delivery or discharge tube 10, the upper end of this tube being disposed a suitable distance above said bottom plate, while the lower end of said tube is provided with a plurality of upright slits 11 and with external screw threads 12. En-
gaged with the threads 12, are similar screw threads which are formed internally of a perforated cap member 13, the curve and threaded wall of thiscap gradually decreas ing in diameter from its upper to its lower end as most clearly disclosed in Figs. 3 and 4, this provision being made for a reason to be hereinafter more clearly described. In the present case, the tube is shown as pro vided with a collar 14 which may be soldered, brazed, or otherwise secured to the bottom plate 4 as indicated in the drawing. Housed within the tube 10, is an absorbent delivery member 20 whose lower end pref:
erably terminates about flush with the lower end of said tube, while its upper end is. curved downwardly as seen at 21 to allow it to depend into the body of disinfecting fluid 22 which is trapped-in the reservoir before described. By this construction, such disinfecting fluid is drawn by capillaryattraction through the absorbent member 20 and is allowed to drip from the lower end thereof through the perforated vcap member 13. The amount of such fluid allowed to be discharged, may now be effectively regulated by rotation of said cap member in the proper direction. Needless to say, if the flow is too rapid, the cap member is tightened upon the lower end of the tube, thereby contracting such lower end and compress ing the delivery member 20, thus checking the supply of fluid. On the other hand, if it is desired to have liquid discharged more rapidly, the cap member may be loosened with an opposite result. Regardless of the manner in which. the cap member 1s turned, however, it is effectively held in adjusted position by a spring which depends from the collar 14 and whose lower end is shaped to engage a plurality of notches 26 with which an annular bead on the lower end of the cap member is pro vided.
description and the accompanying drawing,
that the article is comparatively simple, may he therefore inexpensively marketed, and that it will be a very efficient device for Copies of this patent maybe obtained for carrying out the object of'the invention; namely, to disinfectthe contents of refuse containersand to thereby destroy obnoxious odors which may otherwise prevail.
A device of the class described comprising a reservoir adapted to contain a disinfecting fluid, a delivery tube leading outwardl y from said reservoir and having :its outer end provided with a plurality of longitudinal slits, an. absorbent feed member: housed with said tube and having its inner end disposed in the reservoir,and a ,perforated tube compressing; cap threaded on the outer end of the tube, whereby the discharge of fluid from said tube-may be varied by compressing the feed member.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
