DOG AND PET TOILET Filed Aug. 16, 1965 United States Patent O This invention relates to a household pet toilet designed more particularly for the use of cats and dogs but which may be also adapted for use by other animals.
An object of the invention is to provide an inexpensive and eicient sanitary toilet device that is adapted to be permanently installed in the oor of a dwelling and to be connected with the plumbing of the building and used to flush out the excrement deposited by the animals conned within the house.
Another object of the invention is to provide a device of the class stated which animals may use Without discomfort and with regard to which there will be nothing they might object to, thus providing a toilet device which a pet may be readily trained to use.
A further object of the invention is to provide a device that will be an improvement upon others of its class with regard to general simplicity of construction, one which may readily be installed, which will not materially disfigure t-he appearance of the room, and which will operate in a more dependable efficient manner.
Other objects and advantages will be in part evident to those skilled in the art and in part pointed out hereinafter in the following description taken in connection with the accompanying drawing, wherein there is shown by way of illustration and not of limitation a preferred embodiment of the invention.
In the drawing;
FIGURE l, is a planned view of a toilet facility construction in accordance with the invention,
FIGURE 2, is a vertical section view taken along line 2 2 of FIGURE 1, looking in direction of arrows, and
FIGUREl 3, is a fragmentary view showing an operating detail.
For a more detailed description of my invention, reference is now had to the accompanying drawing 4wherein the numeral designates generally a chamber or enclosure-forming member which may be formed of ceramic material or any similar material and/ or construction of a watertight nature. Mounted separately or formed as an integral part of the enclosure member 10, there is a ush tank 11 with a conventional float controlled valve 12 and a oat 13. The float tank 11 has a ush controlling valve member 14 with a control lever 15 that is actuated by a crank 16 at the outside of the tank. When the llush valve 14 is opened, the contents of the tank 11 will ilow through a conduit 17 to a water distributing system which includes lengths of pipe 18, 19 and 20 that are provided with spaced perforations which will direct jets of ushing water downwardly and along the sides and end wall of the enclosure -member 10. There is an upper level of pipes 18 and 19 which serve to flush the walls of the enclosure and also a lower level of pipes 21 which serve to provide for a iiushing of the floor of the enclosure 10. In other words, since it is the custom, particularly with male dogs 3,318,285 Patented May 9, 1967 to urinate against a vertical surface, these systems of pipes 18 and 19 will be arranged along the upper edges of the confining walls and similar jet-producing pipes may be disposed adjacent to the floor as designated by the numeral 21. The oor of the enclosure is shown in three different angularly inclined surfaces 22, 23 and 24 which provide a trough-like arrangement that will direct the flushing water and excrement into a drain outlet 2S, which will preferably be connected to a sewer for nal disposal.
With this arrangement, the flushing water tank 11 will be automatically filled following each operation of the ush controlling valve 14 as is well understood in the art and to render the device less objectionable, I have shown the end of the enclosure 10 remote from the flush tank 11 as having two single doors 26 that are biased into their closed position and can be easily displaced to permit the entrance of a pet with a minimum of resistance. In this manner, the pet enters the enclosure 10 in a direction substantially parallel with the longest dimension of enclosure 10 and since t-he doors 26 are so desgined as to close following the entrance of a pet, this will prevent an exit at this point. For an exit from the enclosure I have shown one side as having similar spring-pressed doors 27 which swing outwardly when the pet desires to leave the toilet facility. As in the case of the doors 26, these doors 27 are designed to swing only in one direction and, therefore entrance to enclosure 10 must be made though doors 26.
As shown in FIGURE 2 of the drawing, the drain 25 is connected to the sewer through a trap 31. Connected with the float control valve 12 there is a water service connection 28 with a valve 28 as is customary in flush tanks of this type.
In FIGURE 3 of the drawing, I have shown a means by which the Hush valve 14 which controls the ushing operation as a connection through a tie rod 29 that is connected at one end to the crank arm 16 and at its other end it is connected through a lever arm 30 which provides an off center connection that will result in a valve operating movement of the tie rod 29 whenever the connected door 27 is opened.
With this arrangement, it can be seen that once a pet has been trained, the matter of toilet will be greatly simplified and all that the pet needs to do is to enter the enclosure through the swinging doors 26 and after having accomplished the purpose of its visit, the pet will be free t-o leave through the doors 27. Then as a iinal operation, the flush tank will come into play and llush away any deposit from the walls and/or floor of the enclosure.
While I have, for the sake of clearness and in order to disclose my invention so that the same can be readily understood, described and illustrated a specific form and arrangements, I desire to have it understood that this invention is not limited to the specific form disclosed, but may be embodied in other ways that wi-ll suggest themselves to persons skilled in the art. It is believed that this invention is new and all such changes as come within the scope of the appended claim are to be considered as part of this invention.
Having thus described my invention, what I claim and desire to secure by Letters Patent is:
In a pet accommodating toilet, the combination of a Walled enclosure having an inclined flooring and vertical side walls, a drainage outlet at a low point in said inclined ooring having connections with a disposal means, a direct entrance opening in an end wall of said en closure having an inwardly swinging door through which a pet may enter said enclosure, a second opening in a side wall of said enclosure having an outwardly swinging door through which a pet may leave said enclosure, said swinging doors being biased to a closed position by suitable means, a flush tank mounted above said enclosure havinga conventional oat control and discharge valve means with an operating lever for said discharge valve means, fiushing water distributing pipes connected to the discharge valve means from said ush tank through ports for projecting jets of water over floor and side walls of said enclosure, and a discharge valve control means connected between the swinging door of said second opening and said discharge valve, whereby the water from said lush tank will operate to wash excrement from the Walls and oor of said enclosure as the pet leaves.
