HENR7 P. ROBERTS, OF BOSTON, MASSACHUSETTS, ASSIGNOR OF ONE-HALF TO J. G. FENNELLY, OF BOSTON, MASSACHUSETTS.
DISINFECTOR FOR DENTISTS CUSPIDORS.
To all whom it may concern:
Be it known that I, HENRY P. ROBERTS, a citizen of the United States, residing in Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Disinfectors for Dentists Cuspidors, of which the following, taken in connection with the accompanying drawings, is a specification.
My invention relates to improvements in disinfectors for cuspidors, particularly for the various styles of fountain cuspidors designed for the use of dentists.
Although the means provided for renovating such fountain cuspidors by flushing them, and discharging their contents into the sewer are very desirable, it is found that the use of such means does not entirely prevent unwholesome conditions in the interior of the cuspidor, and in the air around it. The interior surfaces of the cuspidor and of its sewer connections, especially between the bowl and the trap, are liable to become coated with unsanitary deposits, the eiiluvia and offensive odors from which taint the interior of the cuspidor, and vitiate the atmosphere in its vicinity.
The objects of my invention are to provide facilities for a more adequate disinfection of the interior of such cuspidors, and to afford means for destroying the offensive odors and noxious effects of any unwholesome eftluvia emanating therefrom. I accomplish these objects by the device illustrated in the accompanying drawings, in which:
Figure 1, a sectional view of a dental fountain cuspidor and my disinfecting device located `therein. Fig. 2, an inverted plan of the disinfecting device. Fig. 3, a plan of the disinfecting device With cap covering the wicking removed.
A cuspidor of the type patented to H. E. lVeber under No. 666,718, dated January 29, 1901, is selected for illustration, of which the cuspidor bowl a only is shown in the drawing, it being understood that a trap of any usual construction is attached to the outlet l) and that suitable connections lead to a sewer, and also that water is supplied to the bowl from a suitable supply in any convenient manner. The disinfector con sists of a shell c formed preferably of spun metal, to which a bottom as d is soldered or Specification of Letters Patent.

otherwise attached. A cap as e closes the top of the receptacle within which a thick wicking or piece of felt as f is placed, and the wicking is soaked in a disinfecting liquid an excess of which may stand in the bottom d to be absorbed as required.
F rom the body of the receptacle a conical hood g spreads downward and outward nearly to the bottom of the cuspidor bowl. A row of vents or holes 7L extends round about the upper portion of the receptacle and another row of holes z' is arranged near the bottom of the receptacle.
The disinfector is located in the cuspidor outlet by the spider j which is attached to the cuspidor by the screw 7c passing through the short metal tube Z and threaded in the nut m which is soldered to the spider j.
When no water is flowing in the bowl gases from the sewer connections pass up under the hood g and entering the .receptacle through the holes c' emerge into the room through the holes L, or the gases from the sewer may pass out under the hood but froln proximity of vapor of the disinfectant escaping from the holes h orz' and because of consequent mixing therewith such sewer gases are rendered inoffensive. If water flows in the bowl of the cuspidor fluid friction of the ruiming water with the air near the edve n of the hood carries air from the room along therewith into the drainage connections, and this tends to reduce the air pressure beneath the hood of the disinfector, hence vapor from the disinfectant drawn from the receptacle through the holes i is carried along with the waste water into the drainage connections purifying their surfaces and by diminishing the putrefaction of matter adhering to the drainage connections rendering any gases given off much less harmful.
Attention is called to the arrangement of the parts of the disinfector so that drafts are maintained through the receptacle tending to diffuse vapor from the disinfectant into the air of the rooln or into the drain.
' Having described my invention, I claim and desire to secure by Letters Patent of the United States:
1. In a disinfector, a receptacle for a disi taclefbetwe'en'the" two groups ofi vent-s, subi supporting the" receptacle;*substantially as stantially as described. v described.
2. In a disinfeetor, a hollow .receptacle In testimony whereof I havesigned my provided with rows of vents at the top and naine to this specication in thev presence of 5 near the bottom, a brous substance standing two subscribing witnesses.
in the receptacle, a cap covering the reoep- Y taole, a downwardly spreading hood at- HENRY P ROBERTS' tached to the receptacle just above the lower lVitnesses: y row of vents, and a spider having resilient GEORGE W1 JACKSON, l0 legs adapted to fit the outlet of a cuspidor M. M. BREWERTON.
