I To (LZZ whom, it may concern.-

Be it-known that I, J oimN GUS'IA r Brenner, a subject of the King of Sweden, and a resident of Gothenburg, in the Kingdom of Sweden, have invented certain new and useful Improvements in Devices for Cushioning'the Shockin Watenlipes by Automatic Cocks, (for which I have obtained patents in the following countries, to wit: Sweden, No. 245, dated September9,1885; France, No. 171,291, dated Septenr ber 22, 1885; Denmark, dated September 24, 1885; Austria-Hungary No. 34,994., dated September 26, 1885; Germany, No. 34,876, dated Septe1nber26,1885; Belgium, No. 70,321, dated September 28, 1885; England, No. 11,610, dated September 29, 1885, and Norway, No. 470, dated December 31,1885;) and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which Figure l is avertical sectional view of a portion of a water-closet, showing my improved device applied. Fig. 2 is a vertical sectional view of the device. Figs. 3 and 4 are similar views illustrating modified forms of the device. Fig. 5 is a vertical sectional view illustrating another modification. Fig. 6 is a horizontal sectional view of the device shown in Fig. 5 on the linear 0c; and Fig. 7, 8, and9 are, respectively, a front view, a side elevation,and a top view of the same.

Similar letters of reference indicate corresponding parts in all the figures,

My invention has relation to devices for cushioning the shock in water-pipes caused by the sudden closing of automatic cocks as usually employed in water closets, supplytanks, feeding reservoirs, flushing cisterns,

. and in many other cases where the servicepipes or discharge-pipes leading from the tank or reservoir are provided with automatic or self closing cocks. The sudden closing of these automatic cocks creates a certain shock or concussion, which affects the pipes injuriously, as it is apt to cause leakage as well as waste; and the object of my device is to overcome this sudden shock or concussion caused by the rapid closing of the automatic cock, and this I accomplish by cushioning the shock as the cock is closed, substantially as will be or faucet, D, opens through the other wall of the receiver, said pipe 0 being provided with a flaring or funnel-shaped inner end, which projects over and around the inner end of the inlet-pipe B.

The upper portion of the tank or receiver above the pipes Band C may be bulb-shaped, as shown at E in Fig. 2, or of any other desired configuration, as shown 011 the drawings. Referring to the construction shown in Fig. 2, which is the construction I prefer to use for ordinary tap-cocks and not for water-closets, it will be seen that the lower contracted portion of the tank or receiver A is provided with aperforated partition, F, which separates the main body of the tank from the valvechamber G, the bottom of which is provided with a valve seat or aperture, H, over which fits a ball-valve, I, preferably consisting of a ball of any suitable heavy material having a rubber or other similar elastic covering.

It will be seen that the pressure of the water, partially filling the tank as it enters through the inlet-pipe B, will force the valve against its seat, so as to close the aperture H and 00111- press the air contained in the upper portion, E, of the tank, so that when the cock of the outlet-pipe or discharge-pipe O is opened the water passing from the inlet-pipe B into the flaring inner end of pipe 0 will cause the latter to operate in precisely the same manner as an injector, sucking the water out of the tank A and valve-chamber G, so as to draw the water out of the tank.

It is obvious that the device shown in Fig. 2 will operate in precisely the same manner if its upper portion, E, is made cylindrical and of the same dimensions as the valve-chamber G, my only reason for making this upper portion bulb-shaped being toincrease the capacity of the air-chamber. In some cases it is not convenient or expedient to make the upper part, E, bulb'shaped, and this part may be constructed in a very simple and inexpensive manner from asection of ordinary pipe closed at the top.

. It will be seen that as the water rushes out of the receiver through pipe O,as above stated, the ball-valve I will be lifted from its seat, thereby admitting air into the tank through the aperture 11; but the moment pipe is closed the water entering the 'tank through pipe B will again partly fill the tank, close the valve, and expend its shock upon theinclosed body of air, whichthus operates to cushion the shock and prevent it from spreading and being communicated to the pipes.

'In Figs. 3 and 4 of the drawings I have shown the modification which I consider most suitable for water-closets and similar purposes.

. By reference to the said figures it will be seen that the valve-chamber is placed at the upper end of the tank, and the-ball-valve is in this case a light floating ball, which'may be forced up against the valve-seat by the water rising in a tube, J, which projects from the valvechamberdown into the body of the tank, and through which tube the water is forced upward by the air being compressed within the tank.

In Fig. 3 the valve-chamber is provided at its upper end with a curved tube, J, which will admit air and prevent impurities from entering, while in Fig. 4 the valve-chamber is provided with a partition, K, which has an aperture opening into a chamber, L, provided at one side with an aperture and curved airtube, M. Both these devices operate in 'precisely the same manner.

In Fig. 5 is shown a vertical sectional view of still another modification, a horizontal sectional view of the same being shown in Fig. 6, a front view in Fig. 7, a side elevation in Fig. 8, and a plan or top view in Fig. 9. In this modification of my device the floating ball-valve is confined within a valve-chamber at the lower end of a box, 0, which is inserted through the top of the tank A, its upper projecting part being provided with an air-inlet, M. The inlet pipe B passes transversely through the tank, entering the same at one end, passing out at the other end, and having at its middle, inside the tank, a projecting nozzle, B, which projects into the flaring mouth of the delivery-pipe C. This construction will be found advantageous where it is desired to continue the flow of water through pipe Bas, for example, whereanumber of these devices are connected or combined in a continuous system.

In Fig. 1 I have shown one method of connecting the tank or receiver A to the bowl of a water-closet and to the service-pipe, and from what has already been stated the operation of the device in this connection will require no further explanation.

Having thus described my invention,I claim and desire to secure by Letters Patent of the I UnitecKStates- 1 7o 1. In a device for cushioning the shock in high-pressure water-service pipes caused by closing the cooks, the combinationof a receiver provided with an inwardly-opening valve, an outlet-pipe having an outwardly-flaring inner end, and an inlet-pipe entering the flaring portion "of said outlet-pipe, as and for the purpose set forth.

2. In a device for cushioning the shock in high-pressure water-service pipes caused by closing the cooks, the combination ofa receiver, an inlet-pipe entering the receiver at one side, an outlet-pipe having a flaring inner end fitting around the inner end of the inlet-pipe and passing out through the opposite side of 8 the receiver, a valve-chamber communicating with the lower portion of the receiver and having a valve-aperture opening to the outside, and a ball-valve fitting upon the inner side of the valve-aperture and adapted to be 0 forced against the same by the pressure from within, as and for the purpose shown and set forth.

3. In a device for cushioning the shock in high-pressure water-service pipes caused by 5 closing the cooks, the combination of a receiver having a valve-aperture in the lower end, a heavy ball-valve fitting upon the valve-aperture, an inlet-pipe entering the lower portion of the receiver, and an outlet-pipe having a flaring inner end'fitting around the inner end of the inlet-pipe and projecting out through the opposite, side of the receiver, as and for the purpose shown and set forth.

4. In a device for cushioning the shock in high-pressure water-service pipes caused by closing the'cocks, the combination, with a receiver provided with inlet and outlet pipes, ofa valve-chamber located above said receiver and provided with avalve-aperture at its top, a tube projecting downwardly from said chamber, and a floating ball-valve for closing said aperture, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature 1 I5 in presence of two witnesses.

JOHAN GUSTAF RIGHERT.
