I GERHARD JOAN OTTO DORIS DIKKERS, OF LONNEKER, NEAR HENGELO, NETHERLANDS.

PUMP, INJECTOR, OR THE LIKE.

Specification of Letters Patent.

Patented Nov. 1, 1910.

To all whom it may concern:

Be it known that I, GERHARD JOAN O'r'ro Donrs -DIKKERS, a subject of the Queen of the Netherlands, residing at Lonneker, near Hengelo, Overysel, in the Kingdom of the Netherlands, have invented certain new and useful Improvements in Pumps, Injectors, or the Like, of which the following is a specification.

I/Vater supply devices, such as pumps, injectors, or the like, for steam boilers, are generally arranged in a corner of the boilerhouse where they do not interfere with the working. Necessary repairs of these devices must usually be effected in dark corners, and are inconvenient and expensive as the unscrewing and separation of these apparatus from the pipes is very complicated and subject to frequent interruptions. In order to overcome these disadvantages, by the present invention the flanges and. pipe connections of the water supply devices (pumps, injectors or similar arrangements) which carry or contain movable parts or parts subject to frequent renewals or exchanges, are arranged on a single stationary frame. This frame is arranged to be connected, by known detachable means (such as screw bolts or the like) in such manner that they may be easily unfastened, with the other parts of the pumps, injectors, or the like, which contain the remaining parts in constant connection with the pipes. In order to effect an easy connection, for example, of the two cylinders of a pump or the like to this frame, connecting pipes are provided in the same, which lead from the pipe connections arranged on the frame to the ground or packed surface to which the cyl inders or the like are connected steam or water tight. Further, pi ms or connecting passages are provided in t e connected parts opposite the openings of the said pipes or connecting passages of the frame; the former pipes guide the steam or the water away from the connecting point or back to the same.

The invention is shown in the accompanying drawing in one form on a pump, and in a second form on an injector.

Figure 1 is a side view of a steam pump with the pump cylinder in section, and Fig. 2 is a view of the frame seen from the right side of Fig. 1, the pump cylinder 3 being removed. Fig. 3 is a View of the frame, seen from the left side of Fig. 1, the steam cylinder 2 being taken off, while Figs. 4 and 5 are vertical longitudinal sections through an lnjector.

On the frame 1 (Figs. 1, 2 and 3) the steam cylinder 2 is arranged at one end in the usual manner, and opposite the same, at the other end, the pump cylinder 3. The connection of these two cylinders with the frame 1 is effected in such manner that four T-headed bolts, engage with their T-shaped heads 6 or 7 in square recesses or slots 8 of the frame plates 9 and 10. As shown in the drawings, bolts 4 are employed to detachably connect the steam cylinder with frame 1, and longer bolts 5 are employed to detachably connect the pump cylinder 3 with said frame.

In pumps as hitherto constructed, the steam supply and outlet pipes were arranged on the cylinder 2, while the water inlet and outlet pipes were arranged on the cylinder 3. The removal of the two cylinders, in order to execute repairs, was therefore, only possible if the pipe connections were loosened.

In the present invention,however, as may.

be seen from the drawing, all the pipe connections are arranged on the frame 1, from whence eonnnunicating passages run to the corresponding cylinders.

\Vhen an air chamber is employed, it may be arranged on the top of the rame 1, as may be seen from Figs. 1 and 2, wherein the flanged branch of the air chamber is shown. Further a connecting branch or pipe 11 for the steam inlet is arranged on the frame in such a manner that it is extended on both sides (Fig. 2) permitting the steam su ply pipe to be connected either on the let or on the right side according to desire, the connection not in useat any time being closed, as usual, by a plate. A passage 12 (Fig. 3) runs from the connecting pipe 11 through the frame and the steam cylinder casin 2, into the slide valve chest 13 (Fig. 1). Zinother passage 14 Figs. 1 and 3) 1s provided for the steam out et or exhaust and also connected up to steam outlet pipes 15 provided at each side of the frame. By means of this arrangement, it is possible to easily remove the steam cylinder without affecting the steamsupply or outlet conduits.

At the bottom of the frame (Figs. 2 and 3) a connecting pipe 16 is provided on both sides for the water suction pipe. The water is led through the base 1 to the connected whereby the turned cylinder liner 22, the

valves 18 and 19 and the other parts may be easily removed after having loosened the screw bolts 5.

The improvements may be embodied in other apparatusfor instance, injectors connected with steam boilers. The injector shown in Figs. 4 and 5 consists of three arts, one of which (23) corresponds to the frame (1 aforesaid) of the pump, this part being provided with the flanges 27, 28, 29 and 30, for the pipe connections. Said apparatus further consists of the casing proper,

24:, and the cap, 25. These three parts are connected with each other by means of four bolts 26, so that the cap 25 and the casing 2 1, after loosening the screws, are easily accessible, or may be separated or both taken off from the frame 28.

The connecting pipe flanges 27, 28, 29 and 30 arranged on the frame 23 serve as connections for the steam supply conduit, the

suction pipe, the pressure pipe or the drip p p A valve pipe 31 is arranged in the frame, which is made with a bend and an inclined valve seat, adapted to engage with a flap 32 which may be moved upward. This valve and pipe can be easily removed from the frame 23 after removing the casing 24. As may be seen from the drawings all easily re movable parts, which are known in themselves, such as the steam and water passages and mixing and injecting nozzles of the injectors, are arranged in the casing 24.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:

A fluid supply apparatus, consisting of independently detachable members provided with inlet and outlet ports and inclosing all the moving parts subject to frequent repair, in combination with a unitary frame provided with connections for all the inlet and outlet pipes and having the fluid supply passages connecting the detachable members entirely inclosed in said frame, and registering with the inlet and outlet ports of the detachable members.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
