ROBERT A. BROOKS, OF CHICAGO, ILLINOIS.

TOILET-CLOSET.

To all whom it may concern:

Be it known that I, ROBERT A. Bnooxs, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Toilet- Closets; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to toilet closets and is shown more particularly as a closet adapted for use for railway cars or steamboats though of course useful elsewhere.

Heretofore closets installed on Pullman cars and the like have in some instances been provided with a concave pan adapted to extend beneath the waste outlet of the bowl, and serving, to retain a small amount of water therein sufficient to afford a water seal and to prevent the inward flow of cold air and dust due to the motion of the train. Such constructions are sometimes inconvenient and objectionable owingto the failure of the supply of water which causes the closets soon to become clogged and filthy because of the pan retaining more or less of the waste. Furthermore such closets have heretofore been so constructed that to insert or remove the pan from the closet it is necessary to release the closet from the floor as also is necessary for adjusting the mechanisms for operating the pan for flushing.

The object of the invention is to provide a strong, cheap, simple and compact closet of the class described provided with a pan hinged beneath and closing the opening or outlet in the bottom of the bowl and the edges of which extend upwardly somewhat above and inclose said outlet from the bowl, effectively sealing the same after flushing. It is also an object of the invention to so construct and insulate said pan as to protect the water therein from freezing and to so construct the closet and pan as to enable the pan to be inserted or removed through the bottom of the bowl from above without releasing the closet from the floor and to provide means for operating said pan to dump the contents and to afford a thorough flush and also an after fill for the closet.

An important object of the invention is Specification of Letters Patent.

Application filed April 19, 1906.

Patented Oct. 12, 1909.

serial No. 312,631.

to provide a ver f strong cheap, simple, durable and compact construction, adapted should the supply of water fail to be quickly adjusted to permit the waste passage to remain permanently open thus insuring a gravity discharge from the closet and avoiding fouling the same.

rlhe invent-ion embraces many other novel features and consists in the matters herein-- after described and more fully pointed out and defined in the appended claims.

In the drawings: Figure 1 is a side elevation of a device embodying my invention showing the same installed as in a Pullman car. Fig. 2 is a similar view of the side Opposite that shown in Fig. 1. Fig. 3 is a side elevation similar to that shown in Fig. 2 but showing a slightly different mechanism for operating the pan. Fig. et is a central vertical section of a device embodying my invention: Fig. 5 is an enlarged fragmentary section illustrating the support for the pan. Figs. G and 7 are fragmentary sections illustrating the construction of the pan. Fig. 8 is a fragmentary side elevation of a part of the pan and the mechanism for operating the same. Fig. 9 is a similar view showing a part of the mechanism for operating the pan as shown in Fig. 3. Fig. 10 is a central vertical section of the spring casing showing the push pin therein inverted. Fig. 11 is an enlarged top plan view of the oprating lever for the iiushing valve. Fig. 12 is a top plan view of the closet bowl showing the pan in dotted lines. Fig. 13 is a section taken on line 13-13 of Fig. L1. Fig. 14 is a section taken on line 14-14 of Fig. 13. Fig. 15 is a section taken on line 15-15 of Fig. 13. Fig. 16 is an enlarged fragmentary detail section showing one of the attaching studs in elevation. Fig. 17 is a top plan view of one of the attaching studs.

A s shown in the drawings: The closet constructed of any suitable material, comprises the bowl A which is of the gravity discharge type and is provided centrally in its bottom as shown in Fig. 12 with a relatively large elliptical soil opening which has its major axis longitudinally of the bowl, and the integrally connected outer wall or casing of the closet indicated by A. Said outer casing or wall tapers downwardlyto the base c', which is flanged for attachment to the floor as is usual and through which and in vertical alinement with the soil opening in the bottom of the bowl, isA the waste or soil outlet a2. This is continued downwardly below the base flange a, as indicated by a3. As shown also the usual annular groove (6*, is adapted to receive a gasket which is provided around the outlet and within the base flange to insure a tight joint. Said closet is extended rearwardly at the top of the bowl, as indicated by A2 to afford means for attaching the seat and cover thereto and as shown'is provided with a rounded or inturned edge a5 at the top of the bowl within which is provided a water passage a6, opening into the bowl through closely arranged apertures so t-hat the iushing fluid is directed from the periphery of the bowl toward its central waste outlet from all parts thereof. lVithin the walls A, of the closet and integrally connected therewith and with the outer side of the bowl A, is an integral inwardly directed Hoor or wall al, which affords a small closed compartment, at the front side of the bowl though obviously it may be otherwise situated if preferred. Said compart-ment is connected with the waterway a, at the top of the bowl and receives a part of each flushing discharge through the passage as opening thereinto and which it delivers more slowly through a restricted passage or passages a9, into the bowl at the conclusion of the flush.

An aperture is provided through the walls of the closet on opposite sides thereon and a little at the rear of and above the orifice of the bowl and extended therethrough is a tubular shaft C comprising as shown a relatively short section c2, provided on its outer end with a head c3, and screw threaded at its inner end adapted for engagement thereby with the internally threaded end of of the corresponding but longer tubular shaft section This is externally threaded at its outer end and adapted to engage thereon a crank arm c, whereby said shaft is partly rotated. As shown the shaft is journaled in suitable bearing sleeves c C, secured in the apertures in the sides of the closet.

Rigidly secured to the shaft C at its center is the concave pan C comprising as shown a concave bottom wall 0T which is seamed to or otherwise united with the inner concave bottom 0S affording a relatively large air space therebetween, and an inner wall or layer c, of copper or other suitable metal is provided between the same and between which and the outer wall 0T, is provided a layer of asbestos or other non-conducting material indicated by C10. Said pan is provided at its periphery with an upwardly directed lip c, which acts to extend the same considerably above the orifice of the bowl vwhen in place. rlhe pan is rigidly secured at its rear edge to the tubular shaft indicated as a whole by C, by any suitable connection. As shown said tubular shaft is provided with lips cl2 and 013 one above the other and which are parallel with each other, and which afford suflicient space between the same to engage therebetween the rear edge of the pan. A relatively large aperture is provided through the side of said tubular shaft C and opens into the air space in the bottom of the pan thus providing means for the circulation of warm air from the car or room thereinto and preventing freezing. Said pan as shown in Fig. l2 is oval in shape and is of less width than the length of the opening through the bottom of the bowl and as shown is hinged in such position that when swung upwardly it receives the lower downwardly extending edges of the bowl surrounding the opening and extends somewhat above the saine so that when filled with water it forms a water seal for the bowl.

As shown the water or flushing fluid is delivered to the closet through a flushometer of flushing valve D of any suitable construction such for instance as that set forth in my prior application for flushometer filed December l, 1903, Serial No. 183,790 and which as shown is connected at its lower end d, with a suitable source of supply and is connected in one side through a suitable pipe d with the inlet passage of the closet.

As shown one of the side walls of the closet indicated by cl2, is made considerably thicker than the other walls and is cored to provide an upwardly opening relatively broad passage (Z3 which communicates at its top with the water passage a@ extending around the rim of the bowl. An aperture is provided through said side wall and extending therethrough is the inlet pipe cl from the flushing valve and indicated by (Z5. Said inlet pipe is provided on one side with a longitudinal rib or key cf which engages in a suitable recess, key way or seat in the closet wall and serves to rigidly hold the same from turning.

The inlet pipe is provided with one or more ports opening therethrough into the water passage Z3 and is closed at its outer end except for a very small waste aperture or passage ZT opening through the end thereof into the closet. The extremity of said inlet pipe protrudes beyond the end of the wall of the closet and is screw threaded for engagement in the side of the flushometer and as shown suitable gaskets (ZS, are secured between the inner end of the pipe and the wall of the closet and the outer wall thereof and the flushometer to afford a tight joint.

Means are provided for operating the flushometer at the same time or at approximately the same time that the pan is dumped. For this purpose as shown a lever E is pivoted on the side of the closet and is pivotally connected at its rear or longer end with a escale link c, which extends downwardly and pivotally engages the arm or crank c whereby the pan is actuated. The front or shorter end c3 of said lever is slotted longitudinally and engages a pin e2 secured in the stem (Z9 of the flushing valve, so that as the rear end of saidr lever is elevated as shown in dotted lines in Fig. 2 the actuating stem (Z9 of the lushometer is forced down to start the flush and the pan is swung downwardly to dump its contents. Means are provided for actuating said lever E embracing a lever c4, fulcrumed on the wall or other convenient support adjacent the closet and adapted for manual engagement and connected atits rear end by means of a rod e5 with the rear end of said lever E. Said connecting rod c5 is provided on its lower end with a spring e, which as shown bears against a stationary stop c7, through which said connecting rod passes and its lower end bears on the rear end of the lever E and acts to hold said lever at all times in a horizontal position and the pan elevated.

If preferred the closet may be emptied and flushed by operating the seat. For this purpose a lever E is pivoted on the side of the closet as before described with reference to the lever E and at its short forwardly directed end e3 is likewise slotted longitudinally and engages the pin e2. As shown said stem d10 is lengthened and extends upwardly beside the seat in position to be manually actuated if desired. At the rear end of said lever E as shown is provided a yoke es, in which is engaged a tubular casing Gr within which is a spiral spring g. Said casing as shown is closed at the bottom, and at the top by screw caps f/ and g2 and through the upper cap is provided a central aperture adapted to receive a push pin g3, which at its inner end within the casing is provided with an enlarged head which bears upon said spring and at its upper end as shown in Fig. 3 bears against a suitable striking plate g?, on the under side of the seat near the hinge. The level' 0G, for actuating the pan is provided at its lower end with a laterally directed pin which engages in a suitable aperture in said casing. Pivotally connected Awith the lever E at its rear end is a link G2, which is longitudinally slotted at its upper end and a pin carried on the seat projects laterally into said slot.

The operation is as follows: The closet is secured in position upon the floor in any suitable manner and as shown the flushometer is secured in place by inserting the inlet pipe (Z5, from the inner side of the closet outwardly and screwing the flushometer and suitable packing onto the protruding threaded end. rlhe pan is secured in place either before or after the closet is set. To secure the same in place after setting, the closet pan is passed downwardly through the aperture in the bottom of the bowl and the end of the pipe section c2 is projected inwardly and threaded into the enlarged head c* of said pipe section The crank is next threaded onto the outer end of said section c and adjusted and rigidly secured in place by a set screwclt to give the desired position of the pan when supported to close the bowl. The link c is next connected with the lever E, the for ward end of which pivotally engages the actuating stem for the flushometer. The connecting rod ci is engaged on the rear end of the actuating lever and the closet is ready for use.

ln flushing actuation of the flushometer by means of the lever et, acts to deliver a sutlicient jet of water through the passage Z3 and the annular passage a, at the top of the bowl which discharges into the bowl and pan through the numerous apertures at the top. A considerable portion of the water however passes downwardly into the closed chamber A3 at the front of the bowl, and between the same and the side wall and gradually flows out through the restricted passage a9, after the pan has been returned to position to close the'bowl thus giving an after fill. Obviously any required amount may be delivered into said chamber by providing' a suflicient number of inlet apertures of suitable size leading from the passage o in the rim of the closet. As the flushing begins the pan has already started to swing downwardly under the action of the lever E or E and in consequence the pans are thoroughly washed with the use of a small quantity of water. After the flushing is complete the spring e or g or if preferred a spring within the flushometer acts to stop the flow and to carry the forward end of the lever E or E upwardly and the rear end downwardly again returning the pan to position to close the outlet and to receive the flow for the after ll from said closed chamber. In the construction shown in Fig. 3 the flush may be accomplished by pressing the stem clio downwardly with the hand thereby simultaneously moving` the pan to partly or wholl f open the outlet or if desired the seat may be lifted when the pin g5 engaging the ends of the link elevates the rear end of the lever E moving the pan downwardly and at the same time actuates the flushing valve to provide the flush. Vith either of the constructions should the supply of water fail, the pan may be inimediately adjusted to remain at all times at its lower position or in other words as shown in position such as shown in dotted lines in Figs. 2 and 3, thus having an unobstructed discharge from the bowl. To accomplish this referring first to Figs. l and 2 the link e is disconnected from the crank c when of course the pan swings downwardly by gravity and is unaffected by the actuation of the .lever et.

In the construction shown in Fig. 10 the .push pin g3 is removed from the spring casing G by first removing the cap g2, and the cap is then replaced with the push pin inverted in the casing. This permits the spring casing to slide freely upward in the yoke on the lever E as shown in dotted lines in Fig. 3 permitting the pan to swing downwardly.

In the construction described. freezing can never occur under any natural temperature owing to the fact that the pan is protected on its bottom the only place at which the same is exposed to the outside air by a double layer of metal and of non-conducting material such as asbestos and is also provided with an interior air chamber which is in open communication with the warm air of the car or room through the tubular shaft or pipe C.

Should breakage occur all parts of the closet are accessible and any repairs can be effected to the flushing or pan actuating mechanism without releasing' the closet from the floor.

For convenience in attaching` the closet to the floor and to permit the same to be readily detached Awhen desired the base flange is slotted to receive the attaching studs H. Each of these studs is integrally connected at its bottom with an attaching plate 71. drilled and countersunk to receive screws whereby the same is attached to the floor Y, as shown in Fig. 16. Said attaching plates extend inwardly beneath the Hange which is recessed to receive the same and said studs are secured in place to correspond with the slots in the closet flange when inserted over said stud.

Obviously various means may be employed for actuating the pan in unison with the flushing means and many details of construction may be varied without departing from the principles of my invention.
