My present invention relates to disinfectors intended for general use, but especially well adapted for use in dripping an antiseptic oil into a urinal or a closet bowl.
The object of this invention-is to provide a disinfector that is relatively simple, highly efiicient in operation, rugged in construction and relatively tamper-proof. The invention further provides a disinfector that also acts as a deodor- .10 'izer.
l To the above end, generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.
In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.
Referring to the drawings: Fig. 1 is a front elevation of the improved disinfector;

Fig. 10 is a fragmentary detail View principally in section showing the reservoir by means of ;4E full lines, as the same is placed in the bowl before the valve is opened, and also showing the reservoir, by means of broken lines, supported on the bottom of the bowl with the valve open.
The improved disinfector includes a bowl II v ,having a removable lid I2 and a wall bracket I3. Said lid I2 is in the form of a hood and the shape thereof is substantially vlike that oi the bowl II except that it is inverted and has an open back and a forwardly and downwardly sloping 5o top.
The wall bracket I3, as shown, is a. ilat plate, the lower end portion of which, snugly fits-into a recess I4 therefore in the back of the bowl Il and the upper portion of said wall bracket aliords a closure for the open back of thelid I2. To
detachably secure the bowl I I to the wall bracket I3, I provide a pair of hooks I5 that are cast with said bracket on the face thereof and separably interlock with the rim portion of the'bowl II. To further detachably secure the bowl II 5.1 to the wall bracket I3 I also provide a pair of screws I6 that extend through holes in the wall bracket i3 and have threaded engagement with. lugs Il cast in the lower rear corners of the bowl II. The snug fit of the wall bracket I3 in the 102 recess I4, together with the hooks I5 andthe l screws I6, rigidly secure the bowl II to the wa bracket I3.
Cast with the wall bracket I3, on the face thereof abovethe bowl I I, is a pair 0f laterally spaced 15'*Y upright reinforcing ribs I8.
The lid I2 loosely rests on the rim of the bowlV II and its top and side members cap the respective edges of the wall bracket I3 and thereby hold the lid I2, at its back, positioned on the 20 bowl II against relative lateral shifting movement.
To further hold the lid I2 on the bowl il a dowel pin I9 is anchored at its lower end portion in the rim of said bowl, at the front thereof, and 25;. extends, with a working fit, into a seat 20 therefore in the lower edge portion of the lid I2. This dowel pin IS together with the capping of the lid I2 with the wall bracket I3 holds the lid I-2 on the bowl II against horizontal shifting move- 30;; ment in all directions.
A hidden lock is provided for releasably securing the lid I2 to the wall bracket I3 and includes a headed lockbolt 2|, on said bracket, and a lock seat 22 for said bolt on the lid I2. The 35 lock bolt 2| is mounted for endwise sliding movement in axially aligned holes in a pair of laterally spaced lugs 23. These lugs 23 are cast with the wall bracket I3 on its inner face and at the top thereof. The lock seat 22 is in the 40, form of a bore which extends transversely through a reinforcing rib 24 in axial alignment With the lock bolt 2l. This rib 24 is castwith the lid I2, on its under side and vextends from the front to the rear of said lid and into a notch 45 25 in the upper edge portion of the wall bracket I3. A transverse pin 26, in the lock bolt 2|., be-
tween the lugs 23, limits, by its engagement with said lugs, the endwise sliding movement of the lock bolt 2|. 50
In the upper rear edge portion of the lid i2 .are
notch-like apertures 21 through, certain .of which,
an instrument may be inserted to engage the head of the lock bolt 2| and withdraw the same from its lock seat 22 to release the lid I2 from `the wall 155';
bracket I3. This instrument may also be used to force the lock bolt 2l into its seat 22 and thereby lock the lid I2 to the wall bracket I3.
The wall bracket i3 may be secured to an upright support, such as a wall, by a bolt or any other anchoring device or devices such as screws, not shown. To receive such securing means, a relatively large hole 28 is formed in the wall bracket I3, substantially at the center thereof above the bowl Il, and a plurality of screw holes 29 are also formed in said bracket and spaced about the hole 28, see Fig. 4.
Formed as integral parts of the lid l2 and the bowl II, is a guard reinforcing rib 3B which, in cross-section, is in the form of an inverted V the sharp edge of which projects outwardly from the lid I2 and the bowl II. This rib 5! extends from the rear edge of the lid l2, at the top thereof, to the rear edge of the bowl II at the bottom thereof.
Upper, intermediate and lower rows of vertically elongated apertures 3I, are formed in the lid I2 and the apertures in each row extend along the front and sides of the lid I2.
Within the bowl II are two vacuum siphon systems, but only one of which is in use at a given time. One of these systems is at the back of the bowl II and the other of which is at the front thereof. Each system, when in use, includes a siphon wick 32 held in the shape of a Siphon tube. The wick 32 when used in connection with the back system has its short leg held in an upright, channel-shaped member 33 and its long leg is held in an upright tube 34.
When the wick 3l is used in connection with the front system its short leg is held in an upright channel-shaped member 35 and its long leg is held in an upright tube 35. The members 33 and 35 have on their sides, out turned flanges 3'I and 38 respectively, and which iianges are slidably mounted in ways 33 and 4G respectively. These ways 39 and 4! are cast integral with the back and front members of the bowl II, respectively, and frictionally hold the channel members v33 and 35 with their lower ends spaced above the bottom of the bowl l! for the movement of the liquid in the bowl Il to the respective legs of the wick 32. It will be noted that the open sides of the channel members 33 and 35 are turned toward the respective members of the bowl I I and are closed thereby.
'Ihe tubes 34 and 35 are held in upright positions by having their lower end portions itted into sockets in lugs 4l and 42 respectively, cast `integral with the bottom and the respective side members of the bowl il. An upright nipple 43 is mounted in the lug 4I and leads from the lower end of the tube 54 through the bottom of the bowl II. Said bowl il at its under side, is recessed, as indicated at 44, to afford clearance forv a tube 45 tted onto the nipple 43 and only fragmentalily shown by means of broken lines, see Fig. 8.
A second nipple 45 is ntted in the lug 42 and leads from the lower end of the tube 35 through the bottom of the bowl ll, see Fig. '7.
Within the bowl ll is a body of antiseptic dripping oil X supplied thereto from a reservoir 41 in the form of a closed upright can. This reservoir 4I has on its lower end a depending neck comprising a iixed tube 48 on which is telescoped a tube extension 49 having a flaring mouth 50. This mouth 50 loosely rests on the bottom of the bowl I I and supports the reservoir 41 with- `in said bowl and its lid I2.
The tube extension 49 has formed therein, a deep notch 5I which extends from the upper edge of said extension to an aperture 52 in said extension at the junction of the mouth 5U therewith. This notch 5I and the aperture 52 afford a passageway for the flow of an antiseptic dripping oil Y from the reservoir 41 into the bowl I I. The tube extension 49 frictionally holds the tube 48 where telescoped therein. By contracting the tube extension 49, at the notch 5I, its frictional contact within the tube 48 may be increased at will. To lill the reservoir 41 with an antiseptic dripping oil, it is turned into a position in which the tube 48 and its extension 49 are at the top thereof.
At the time the reservoir 4l is placed in the bowl lI the same is inverted, and to hold the liquid Y therein I provide a valve 53, which, when closed, is seated on the inner end of the tube 48, see Fig. 10. This valve 53 is provided with a stem 54 which extends axially outwardly through the tube 4S and its extension 49. The outer end portion of the valve stem 54 is bent to form a ring 55, which, when the valve 53 is closed, extends partially outwardly of the mouth 5U. It will be noted that the external diameter of the ring 55 is somewhat larger than the internal diameter of the tube 48 and acts as a stop to prevent the valve 5G from dropping into the reservoir 4'1, when said reservoir is turned into a filling position.
Formed in the tube 48, close to the respective end of the reservoir 4l is a hole 56, for a purpose that will presently appear.
During the placing of the reservoir 4l in the bowl II, the ring 55 engages the bottom of said bowl and opens the valve 53, by stopping further movement thereof, as the reservoir 47 is lowered to position the mouth 50 on the bottom of the bowl Il. When the valve 53 is open the liquid Y will ow from the reservoir 4'1 through the notch 5I, aperture 52 and the hole 56 into the bowl l! until the level of the liquid X in said bowl is just above the hole 55. This level of the liquid X is maintained until the liquid Y in the reservoir 4! drops below a level in which the hole 55 is uncovered and thereby breaks the partial vacuum in the reservoir 4'.' and stops further siphoning of the liquid X from the bowl II.
When the improved disinfector is used in connection with a closet bowl the same is attached to a suitable support thereabove and the tube 4l has its delivery end extended into said bowl to drip the liquid therein. In this use of the disinfector the wick 32 will be placed as shown in Fig. 4.
Ii the improved disinfector is to be used in connection with a urinal, the wick 32 will be placed as shown in Fig. 6, and the disinfector mounted in a position in which the liquid X will drip from the nipple 46 directly into the urinal.
At the same time, the improved device is used as a disinfector, the same may also be used as a deodorizer and in which case a tubular wick 5'I is telescoped over the reservoir 4l with its lower end portion extending into the liquid X, see Fig. 2. Fumes from the liquid X held by the wick 5'I will escape from the disinfector through the apertures 3l and enter the room in which the disinfector'is placed.
To assemble the several parts of the improved disinfector the lower end portion of the wall bracket I3 is placed in the recess I4 and slid downwardly therein to interlock the hooks I5 with the back rim of the bowl II and thereafter the screws I 6 are inserted through the holes therefor in said bracket and screwed into the lugs I'l. Next the wall bracket I3 is fastened to a wall or other support by means of a bolt or other anchoring device inserted through the hole 28 or by screws inserted through the holes 29.
Before the lid I2 is secured over the bowl II the reservoir 41 is lled with an antiseptic dripping oil and then placed in the bowl II as heretofore described. If the antiseptic oil is to be dripped from the nipple 43 the wick 32 will be placed, as shown by full lines in Figs. 2, 4, and 8. Or if the antiseptic oil is to be dripped from the nipple 46 the wick 32 will be placed as shown by broken lines in Figs. 2, 6, and 7.
After the reservoir 4l is in place in the bowl II, the lid I2 is placed on said bowl with the dowel pin I9 in its seat 20 and the rear edge portion of the lid capping the wall bracket I3. Next the lock bolt 2I is moved endwise into the lock seat 22 to lock the lid I2 to the wall bracket I3.
When the wick 3I has become saturated with the antiseptic oil the siphoning action will start and said wick will continue to drip oil until the partial vacuum in the reservoir 4l is broken by the lowering of the liquid level into a position in which it uncovers the hole 56.
It is evident that when the wall bracket I3 is secured to a support, the bowl Il cannot be removed therefrom for the reason that the screws I6 are covered by said bracket and can not be reached.- Neither can the wall bracket I3 be removed from its support for the reason that its fastening device is covered by the lid I2 which is locked to the wall bracket I3.
Unless a person is familiar with the location and operation of the hidden lock, which secures the lid I2 to the wall bracket I3, he cannot gain access to the interior of the device.
It is well known that vandals often try to break, mutilate or otherwise damage disinfectors in the toilets of public' buildings, schools and the like. disinfector with a bar or clubl or by striking the same with the fist. The primary purpose of the reinforcing rib 30 is to protect the disinfector from being damaged by a blow thereon. Furthermore, the lid I2 is securely held on the bowl II and cannot be twisted or pried therefrom.
The amount of liquid dripped from the disinfector may be varied at will by moving the tube 48 axially into the tube extension 49 to vary the height of the hole 56 above the bottom of the bowl II or in other words to vary the level of the liquid in the bowl I I.
