RESERVOIR-CUSPIDOR.

Specification of Letters Patent.

Patented Sept. 22, 1914;.

To all whom it may concern Be it known that I, HENRY E. WEBER, a citizen of the United States, residing at Canton, in the county of Ohio, have invented a certain new and useful Reservoir-Cuspidor, of which the following is a specification.

The invention relates to a reservoir cuspidor for use in places where connections with water supply and sewer systems are not available or desirable; and the object of the improvement is to provide a complete, convenient and sanitary cuspidor which will present a neat and clean appearance. The adhesion of sanguinary saliva to the bottom of a cuspidor cannot be overcome by an intermittent flushing of the same, and, when such flushing is depended upon to remove the saliva, a certain portion of the same with its disease-breeding germs will accumulate and ultimately dry in the cuspidor, which renders it unsightly as well as unhealthy. This difficulty is overcome by normally flooding the bottom of the bowl, so that the saliva will not impinge the same, and by frequently draining off the flooding water and replacing it with a fresh and clean supply.

The invention also includes other improvements of construction, arrangement and operation, which are illustrated in the accompanying drawings,'forming part hereof, showing a preferred embodiment of the invention, in which- Figure 1 is a side elevation of the reservoir cuspidorg. Fig. .2, a sectional elevation of thesame; Fig. 3, an enlarged fragmentary section of the pump valves and adjacent parts; Fig. 4, an enlarged fragmentary section of the bowl support and outlet valve, also showing the pump handle and flushing nozzle; Fig. 5, a fragmentary perspective view showing details of the bowl-bracket stopping device; and Fig; 6, a perspective view of the cuspidor showing analternate manner of supportingthe waste bucket, and 1 showing the bowl and bucket brackets rotated from above the reservoir, and the bucket removed from its bracket.

Similar numerals refer to similar parts throughout the drawings.

The reservoir cuspidor is composed of the reservoir 1, on which is formed or'connected the base 2: the tubular stem 3, which forms the pump cylinder and is secured to Stark and State of the socket 1 formed on one side of the base, by means of the nipple 5 and the union coupling 6, and to the reservoir by the connectng arm 7 the

waste bucket

8 or 8*, which Is supported at the top of the reservoir, either by resting directly thereon, as shown in Figs. 1 and 2, or by resting in the bracket 9 which is rotatably supported on the tubular stem 3, as shown in Fig. 5; and the bowl 10, which is supported at the top of the bucket by means of the bracket 11 rotatably supported on the tubular stem.

The reservoir 1 is preferably made, as shown, in the form of a round vessel open at the top and provided with the enlarged base 2 on the bottom, which constitutes a firm support for the cuspidor. The socket 4 is formed or secured on one side of the base and communicates with the bottom of the cavity of the reservoir by the port 12. The check valve 13 is provided in the lower end of the tubular stem and the plunger 14 is located and adapted to operate 'endwise in the tubular stem, which plunger is pro vided with the handle 15 on its upper end, and is made somewhat less in external diameter than the interior diameter of the tubular stem, thus leaving the intervening annular chamber 16 around the plunger. The stufiingbox 17 is provided at the upper end of the cylinder, and the flexible cup-valve 18 is secured to the shank plug 19 on the lower end of the plunger; and the resilient washer QOis preferably secured to the lower end of the valve-shank and serves to cushion the contact of th plunger against the check valve. i

The flushing nozzle 21 is connected by the swivel-union 22 to the tubular branch 23 on the side of the upper end of the tubular stem and communicates with the cavity thereof; which nozzle is suitably bent so that by a rotation of the nozzle on its swivel union, the discharge end 24 thereof may be brought down to or near the bottom of the bowl, as shown in Fig. 2, or the nozzle may be raised so that the overhanging portion thereof will be elevated entirely above the rim of the bowl, as shown in Fig. 6, or by broken lines in F is. 2.

In the operation of the pump, when the plunger is raised the edge of the cup-valve is flexed outward and impinges the wall of the cylinder, thus sucking the water from the cylinder through the port 12 and up ward through the socket 4 and check valve against which the valve 39 is adapted to be 13 into the cavity of the tubular stem; and at the same timelifts such water as may be above the cup-valve and discharges it through the nozzle. And, when the plunger is depressed, the check valve 13 is closed by the weight of the column of water above it, and the displacement of the plunger forces the water upward around the same and outward through the nozzle.

The

waste bucket

8 or 8 is preferably made cylindrio in form, as shown, with a holding capacity slightly less than the ca- When the bucket is on the rim 25 of the respacity of the reservoir. supported directly ervoir, as shown in Figs. 1 and 2, the depending flange 26 is preferably provided around the bottom of the bucket, which flange overlaps the rim of the reservoir and centers and retains the bucket in place there on; and the depending flange furthermore prevents any waste which may overflow from or run from finding its way into the reservoir.

The bucket bracket 9 is preferably made in the form of a shallow cup, which may have its bottom apertured, as shown, in which cup the bottom of the bucket is rea ily centered and retained; and the bracket is provided with the arm 27 and the bearing sleeve 28 which is journaled on the tubular stem and supported on the collar 29 of the arm 7" which secures the stem to the reservoir. The set screw 30 is preferably provided in the bearing sleeve by means of which the bucket bracket may be secured in any desired position of rotation. In use, the bracket 9 is normally located immediately above the top of, and in axial alinement with the reservoir, as shown by broken lines in Fig. 6; but, when it is desired for filling the reservoir, or to remove the bucket without rotating the bowl, the bracket is rotated from above the reservoir, as shown in Fig. 6. The bowl bracketgll is preferably made bell-shaped in form with its rim, 31 normally located immediately above the rim 32 of the bucket, thus forming an arched cover for the same;

seat 33 is provided on the upper side of the bracket in which seat the neck of the bowl is adapted to be secured, preferably with the intervening resilient washer 34. The discharge ajutage pipe 35 is axially formed, or secured by screwing, as shown, in the bowl bracket, and its lower end 36 depends freely a considerable distance below the body of the bell-shaped bracket,but terminates above the level of the rim thereof. The funnelshaped partition 3"? is provided in the drain pipe, the lower rim 38 of which is located at a substantial annular interval within the wall ofthe ajutage pipe above the lower end thereof, and constitutes a seat 4, by means of the push down the sides of the bucket,

and the countersunk bowl-v closed; which valve is secured on the inner end of the lever 40 which is fulcrumed at 41 in the hollow arm 42 of the bowl bracket and preferably above the plane of the valve seat. The outer end of the lever 40 is normally depressed to close the valve, as shown in Fig. 2, by means of the spring 43 adjustably mounted inthe bracket-arm, and the same end of the lever is adapted to be elesv as shownfin Fig. pin 44 mounted in the socket 45 in the bracket arm, and provided with the stop collar 46 adapted to engage the guide flange 47 pin in the socket.

vated to open the valve,

The bowl 10 is preferably secured: in its seat in the bracket 11 by means of the funnel-shaped collar 48, the neck of which is connected, as by screwing, with the upper end of the drain pipe 35., and the flared end of which collar is adapted to impinge around the bottom of the bowl above its neck, preferably with the intervening resilient packing rin 49, thereby clamping the neck of the bowT in its bracket-seat.

The bearing sleeve 50 is provided on the end of the bowl-bracket arm 42, which bearing is journaled on the tubular stem 3, and its lower end rests on the'supporting collar 51 which is secured to the stem. The annular recess 52 is provided inthe lowerend of the bowl-bracket sleeve 50 part way around the same, in which recess the stop pin 53-, formed or secured on the supporting collar 51,projects and serves to limitthe rotation of the sleeve in either direction by impinging the respective ends of the, annular recess therein. These parts are so proportioned swinging of the bowl-bracket in one direction is stopped when the bowl is in axial alinement directlyabove the reservoir and the bucket, as shown in Figs. 1 and 2, and

its lateral swingingin the opposite direction is stopped when the bowl audits bracket have cleared the side of the bucket, as shown in Fig. 6. The set screw 54 is preferably provided in the bowl-bracket sleevev by means of which the same can be locked ina desired position of rotation.

In the use of 'the cuspidor, the reservoir is charged with clean water by means of the waste bucket, which is removed for that. purpose either by elevating thev discharge nozzle and swinging the bowl to one side, when the bucket 8 issupported on the reservoir; or, if desired, by merely rotating the'bucketbracket when thebucket 8 is supported independently of the reservoir.- The empty iii;

bucket is then placed in normal position above the reservoir, and the bowl, if not already there, is swung into normal position directly above the bucket, and the flushing nozzle is depressed to bring its discharge end to retain the and arranged that the lateral near the bottom of the bowl. The pump is then operated and one or more strokes of the plunger serves to fill the bowl so that its shown in Fig.

2, with fresh and clean the reservoir, it being-understood that the discharge valve 39 is normally closed, by action of the spring 43 thus retaining the water in the bowl. When the cuspidor has been used to such an extent as to render a change of the water therein necessary or desirable, the discharge valve is opened by pressure applied to the free end of the push pin 44, whereupon the water in the bowl flows downward through the ajutage pipe into the bucket, in doing which the freely depending rim of the ajutage pipe serves to prevent any portion of the water from running or splashing against the bell-shaped cover or over the rim of the bucket, thus bucket resting upon the rim of the reservoir and having a depending flange overlapping said rim, and a laterally swinging bowl supported above the bucket.

cuspidor including a bucket, a bellshaped bracket independently supported above and normally covering the bucket and a bowl mounted on the bracket.
