Specification of Letters Patent.
Patented May 11, 1215.
Original application filed. April 25, 1910, Serial No. 557,410. Divided and this application filed August 14, 1911, Serial No. 643,942. Renewed February 23, 1915. Serial No. 10,124.
To all whom it may concern:
Be it known that I, BERNARD BENSEN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Flushing Mechanism, of which the following is a specification.
This invention relates to the general style of flushing mechanism which acts automatically to flush the bowl of a water-closet when the seat of the same is released, and is a division of my application, Serial No. 557,410, which was filed April 25th, 1910 and matured into Patent No. 1,004,349 on September 26, 1911.
This present application is directed more in detail to the construction of the dash-pot and associated parts which control the speed of release of the tripping finger when the seat is released.
It will be appreciated that in many locations and under certain conditions the space in which an apparatus of this kind can be located is small and difficult of access so that the device, in order to be entirely satisfactory, should be constructed in as compact and simple a manner as possible.
One of the main objects of this invention is to locate the dash-pot which controls the release of the seat within the conduit leading from the water-valve of the flushing device to the connection with the closet, thus obtaining a central location for the same and minimizing the total amount of space occupied.
Other objects and uses will appear from a detailed description of the invention which consists in the features of construction and combination of parts hereinafter described and claimed.
Referring to the drawings, Figure 1 shows a side elevation of the complete flushing device; Fig. 2 shows an enlarged plan section taken on the line 2-2 of Fig. 1, looking in the direction of the arrows; Fig. 3 shows a detail vertical section of the dash-pot and water-conduit; and Fig. 4: is an enlarged detail section of the upper portion of the dash-pot and piston.
As before stated, this invention relates particularly to the method of mounting the seat-release control dash-pot, but for the purpose of showing a complete operative structure I have shown an entire flushing device, in elevation, in Fig. 1. Also in Fig. 3 I have shown the end of the lever arm which extends from the seat to the flushing device.
In the drawings, the numeral 5 designates the casing which incloses the water-valve.
In Fig. 2, the water-valve is designated by the numeral 6. It has a vertical movement which is controlled by means of the stem 7 in the ordinary manner. When the valve 6 is lowered, water can flow up through it and out through the passages 8 and neck 9 into the annular passage 10 and, finally, to the connection 11 whence it passes into the bowl of the closet or the pipe leading thereto.
Referring to Figs. 1 and 3, the numeral 12 designates an operating lever which is raised and lowered by the movements of the closet seat. This lever acts upon a roller 13 carried within a frame 14:, the upper end of which is attached to an operating pin 15 and the lower end of which is connected to the piston rod 16 of a dash-pot 17. The spring within this clash-pot always exerts a downward pressure on the piston rod of the same, thus constantly tending to restore the frame 14 and the operating pin and lever to their lowered or normal position.
For the purpose of economizing' in space and obtaining as compact and rigid a construction as possible, the dash-pot is extended down through the central part of the passageway 10. To this end said passageway is divided by a circular wall 18, the upper portion 19 of which is flared out slightly as shown in Fig. 3. The dash-pot cylinder comprises a drawn tubing'shell 20, the upper end of which is threaded within a cap 21 which, in turn, is threaded into the flared out portion 19. The lower end of the shell may be closed in any suitable manner as by means of a nut 22. Also a washer 23 may be used for securing a tight connection between the tubing 20 and the cap 21. The piston rod 16 carries at its lower end the piston 24: which is so formed that it can be quickly raised up but so that its rate of downward movement will be checked. In the particular construction illustrated, it is provided with a hole 25 of comparatively large size and a valve 26 which may seat upward to close the hole. This valve, in turn, is provided with a very small hole 27 amount of tension in the spring.
particular construction illustrated, the piston rod has its lower end screw-threaded into a head 30 carried by the piston and its upper end suitably secured to a head 31 which, in turn, is attached to the frame 14 by means of a pin 32. By withdrawing the pin, the frame may be disengaged from the head so that the latter may be rotated. A set-screw 33 serves to effect a rigid connection between the piston rod and the head so that by rotating the head with a wrench or similar tool the piston rod will be threaded up or down within the head 30 of the piston. In this manner the length of the spring can be increased or decreased, thus decreasing or increasing its tension.
In the particular construction illustrated, the cap 21 has its upper surface socketed to provide a recess 34, and a boss 35 surrounding the piston.- A washer 36 surrounds the piston rod and is interposed between the boss 35 and the head, so that when the latter is completely released, as by drawing the pin 32, the spring within the dashpot will draw the head down to clamp the washer very tightly against the boss and thus prevent leakage.
It is appreciated that a slight amount of oil may be carried by the piston rod from the interior to the exterior of the cylinder oil will collect and each time the device is actuated. In order to catch such oil, I have provided a pocket or recess 35 above mentioned in which such eventually leak down into the cylinder.
' will be'raised when it is released.
I wish to call particular attention to the fact that the dash-pot serves to regulate the rate at which the lever 12 descends and, consequently, the rate at which the seat In constructions heretofore used where there has been no dash-pot provided for regulating the speed of lever-release, the spring causes the seat to rise suddenly and with .a jarring noise, which is disagreeable and undesirable in other ways. Furthermore, the'dashpot, by restoring the finger 15, causes the valve to open slowly, and, therefore, a more satisfactory flush is secured.
I wish also to call attention to-the fact that by placing the spring within the dashpot as is done in the present construction, the same is completely immersed in oil so that it will not rust and, consequently, will have practically the same strengthafter a long service as originally. v r
I claim: J r
1. As a new article of manufacture, a
water delivery conduit for a flushing de-' vice, having one end adapted to be connected to a water valve and having its other end terminatingin a bowl connection, there being a hollow cylindrical partition extending vertically. through the conduit and serving to divide the same into two passage ways, said passage ways being connected together at both ends, the upper portion of; V v8O f the partition being threaded, and adashpot extended down through the space inclosed by the partition and having its upper end threaded into engagement with the threads on the upper end of the partition.
2. As anew article of manufacture, a water delivery conduit for a flushing device having one end adapted to be connected to a water valve and having its other end terminating in a bowl connection, there being a partition extending verticallythrough the conduit and serving to divide the same into two passage ways, said passage-ways being connected together'at both ends, said partition inclosing a vertical space through the body of the conduit, and a dash pot entered into said space and secured. to the partition.
