This invention `relates to new and-useful improvements in folding wash basins and particularly to basins for use in railway cars and the like. l

5 `Thfef principal objects-of the invention are toprovide a wash basin` which can 'be folded i into or: against. aV wall' without undue shock `toi the'I basin or `its supporting'` mechanism; to providemeansl for automatically cutting 19p o-ff. the water supply whenv not in. use, and to provide means for `emptying the basin of its contents before it goes into the inoperative position. y According, to my invention I `provide a 15` wash basin mounted on suitable brackets pivotally secured by any suitable` means toa wall. The 4hot and covldwater connections are made toa a special cut @if cock which is so arranged that the watersupply tothe basin `is cut ofi 2Q when the'basinis in. its folded or inoperative position. The centre of the cock is arranged.

plan view foi my improvedl Referring more particularly to the drawings, 11 designates a hand' basin ofthe usual type which is secured to a bracket 12 at the sides 13. The brackets are pivotally secured to supports 14. extending outwardly from the wall 15 of the4 car or the like. `The pivot on one side may be the bolt 16 and on the other sidev a pin 33 may be used, said pin engaging with arecessed extension 17 Jfrom they waste pipe elbow 18. This extension holds the waste pipe at thispont on the pivot centre. The basin has the

usual faucets

19 and 20 Jfor the `flow into the basin and the faucet 21 or the dental pipe 22. The details of the faucets are not shown as they are of the usual con struction. A waste lever 23 is also provided for controlling the discharge of water from the basin. The `connections between the lever 23 and the waste pipe 24: are not shown. The waste pipe is connected to the bottom of the `basin by means of the casting 25. The waste pipe-24 isprovided with a connection 29 to the elbow 18. This connection will allow pivot ing movement-and is shown in detail in Fig ure 6. The waste pipe has rotatably mounted thereon an internally threaded nut 30, the threads of which engageY with the threaded end 31 `ofthe elbow 18. Between the adjacent ends of therelbowl and the waste pipe a packing 32 is provided to make a watertight joint between them. AThe drain pipe 34e from the elbow extends downwardly and may be secured` by any suitable meansto the wall.

T he elbow and drain pipe are held against movement but "the connection 29 will allow pivoting movement between the waste pipe and the elbow.` The

water supply pipes

35 and 36 are secured` to the car and are connected to a stop cock 37, details of which are shownV yin Figure 5. The hot water supply pipe 35 is connected to thecock casing 38 through-u` the internally threaded aperture 39a The aperture 39 is adapted to register with thel entrance 40 of a passageway ilV formed in the central conically'shapedcore 12 of the` cock which has an externally threaded portion 43 extending beyond the end of the casing. i Y

This portion 43 passes throu h a bracket 111 secured to the wall oi a car bo y or the like and is rotatably mounted therein and held in place b the nut 45. The passageway 41 extends t rough the portion 43 and registers with the hot water pipe connection 46, the outlet from which is controlled by a faucet. The cold water connection pipe 36 is connected to the internally threaded aperture 47 in the casing 38 which registers with the opening to a passageway 48 formed in the tapered or conically shaped core 42 of the cock. T his passageway extends towards the end 49 of the core and is independent of the passageway 41. The end 49 is threaded externally and is connected by any suitable piping to the cold water faucets on the basin and dental section. The core is drawn into the casing by means of the nut 45. To form a watertight joint between the end 50 of the casing and the core,

double glands

51 and 52 are provided. Gland 51 engages with the internally threaded portion 5() and a packing ring 53 is provided to prevent the water from leaking through between the gland 51 and the cock casing. The gland 52 engages with an internally threaded portion of the glandv 51 and is adapted to expand the packing ring 54 by pressing it against a rib 55 formed in the said gland 51. The expansion of the packing ring 54 seals the joint between the gland and the end 49 of the core. This construction allows the core to rotate within the casing to bring the entrance to the passageways into and out of register with the supply pipe when the basin is in the operative or inoperative position. Figure 1 shows the basin in the operative position, that is, ready for use and in theopen position. The waste lever 23 has a lever 56 connected thereto and adapted t`o move therewith. This lever is connected by a link 57 to the lever 58 secured to a spindle 59 rotatably mounted in the basin brackets and connected to a lever 60 and connecting rod 61 toa locking catch 62. The locking catch is pivotally secured to the basin brackets and its hooked end 63 projects upwardly through a slot 64 in the supports 14.

lVhen the basin has water therein and the waste plug closed, the waste lever is in such a position that the hooked part of the locking lever engages with the edgerof the slot in the support 14. When the waste lever is in the position tohold the plug in the open position, the hooked end is down clear of the support and the basin may be turned upwardly i about the pivot. This arrangement ensures that the basin must be emptled before it is raised. The basin is provided at its front with a downwardly projecting arm 65 the end 66 of which is bifurcated and adapted to extend over the sides 67 of a cylinder 68, the sides of which are provided with guides adapted to receive guide blocks 69 pivotally attached by pins 70 to the bifurcated ends. These guides extend beyond the end 71 of the cylinder and are connected together and to a piston rod 7 2. The piston rod extends into the c Ylinder and is provided with a piston 73. n air vent 74 is formed in the walls of the cylinder to regulate the discharge of air therefrom. The cylinder is secured to a tray 75 secured to the back 76 of a chair or panel which is hingedly attached'to the support 14 by the hinges 77. The centre of the hinges is positioned below and in front of the basin pivot.

It will be seen that in operation the basin, when moved from its operative position shown in Figure 1 to its inoperative position against the wall, has its supply of water automatically cut of and it will also be seen that, before this movement can take place, the waste plug must open to release the lock or catch. This combination drain control and locking arrangement ensures that the basin must be emptied before it can be moved against the wall. The pipe connections for the water supply and discharge are arranged so that they pivot about the basin connection pipe. This arrangement allows the pipes to be connected without the necessity of using the flexible pipes or the like. To lessen the shock of closing and opening, the piston working in the cylinder cushions the movement. The cylinder ybeing` connected to the panel or chair back which operates on a pivot below and in front of the basin pivot makes the piston operate to cushion the movement of the basin against the air in the cylinder. The basin has a soap retaining recess 78 which is partially covered by a hood 79, so that, should the operator leave the soap in the said recess when the basin is swung upwardly, said soap will be prevented from falling towards the hinged portion of the basin.

The device is simple to operate, as will be seen, means are provided for its safe operation. The device can be folded against a wall and by providingmetallic pivot joints in the pipes, the danger of cutting the waste or water connections is reduced to a minimum.

Having thus described my invention, what I claim is:

1. In a folding basin for railway cars and the like, a wash bowl, bracket secured to and depending therefrom, a support extending outwardl from the car body, pivot pins connecting t e support to the bracket to allow hinging movement of the bowl water land waste controlling means mounted on the bowl, hot and cold water supply pipes connected to the water controlling means said pipes belng conected to a double stop cock, adapted to cut off the water supply when the bowl is in the vertical position, the central pivoting axis of said cock being in alignment with a line passing through the pivot pms, a waste connection having a swivel joint therein in alignment with the axis of the cock, a Waste control lever and means n operable by the movement of said lever to lock and unlock the basin. y
