INJECTOR.

fiiI-ECIFECATION forming part of Letters Patent No. 345,200, dated July 6, 1886.

Application liled December 17, 1885.

To all whom it may concern.-

Be it known that LOTTO VVESTPHAL, a cilizen of Germany, residing at Buekau, near Magdeburg, Germany,haveinvented new and 5 useful Improvements in Injectors,of which the following is a specification.

This invention relates to injectors such as are illustrated by my Letters Patent No; 312,591, dated February 17, 1885; and it consists in the combination of devices hereinafter described and claimed, reference being had to the accompanying drawings, illustrating my invention, in which Figure l is a vertical central section in the I5 plane y y, Fig. 2, of the injector. Fig. 2 is a similar section thereof in the planeg/y,Fig. 1. Fig. 3 is a transverse section in the plane 00.00, Fig. 2. Fig. 4 is aside elevation showing the overflow'nozzles.

Similar letters indicate corresponding parts.

In the drawings, the letter A designatesthe casing of the injector, which is east in three sections, a, b, and c, for convenience of construction, and to facilitate access to the same 25 for subsequent cleanin D is the live-steam-inlet pipe.-

is the water-supply inlet.

D D are the overflow-nozzles, and E is the discharge-opening to the boiler,which is provided with a check-valve, c, to prevent the water from backing.

F is the steam-nozzle secured in the section I) of the casing, and G is the combining-nozzle, which is situated directly below the steamnozzle.

Into the steam-nozzle F extends a steamcone, H, having a solid conical end and astem which extends upward and has a bearing in a bridge, h, extending across the section a of the casing. The stem is provided with guideblocks h and hiwhich work in suitable guideways, 7. and h,located at either side of the section a. The stem is made sectional to facilitate its introduction into the casing,andit consists of a hub having its lower face turned to form a valve, l,which is adapted to bear upon a suitable valve-seat, 1, formed in the mouth of the steam-nozzle 1*. The upper section extends into and is secured to the hub by a screw, 0 z. The steamcone H is raised or lowered so Serial No. 185,957. (Modch) as to lift the valve I to and from its seat by a hand-lever, J, which is connected to said steam-cone. This connection consists of a head-piece, Z, which is secured to one side of the stem of the cone H by the screw 2', or may be cast thereon,and in the said head-piece isa slot, Z, which is engaged by a pin, Z'fleccentrically secured to a disk on a shaft, Z, to which the lever J is secured. The shaft Z extends through a suitable stuffing-box, K, attached to the casing.

An index-arm, K,secured to the casing, and an i ndex-plate, K attached to a downwardlyprojecting arm of the hand-lever J, serve to indicate the position of the valve I and stcamcone.

In the combining-nozzle are formed two series of circumferential overflow-orifices, L L, one series, L, of which is located near the month of the same, while the other series, L, 7) is located near the discharge thereof.

Across the overflow-chamber formed in sectionc of the casing extends an oblique diaphragm, M, which divides this OVCIflO\V-Ci]2tlllher into two separate compartments, in m, so that the overflowing water from the series of dischargeorilices L enters compartmentm, and the overflow from orifices L enters compartment in, whereby the two overflows are completely separated from each other. The S0 overflow-nozzle D, previously mentioned, is in communication with compartment in, and the overflow-nozzle D is in communication with compartment in. Each of the said nozzles D D is provided with an outwardly-open 8 5 ing valve, (1, which valves are shown as springpressed disk-valves, the stems of which are properly guided in bridges d in the nozzles.

By the use of the separate compartments m m for the overflow and the separate overflow- 9o nozzles D D,each communicating with one of the chambers, in conjunction with the valves d in said overflow-nozzles, the injector can be used to draw warm water, since the overfloworifices L L are thus cut off from the outer at- 5 mosphere. The separation of the overfloworifices L and L and the division of the overflow-chamber by the diaphragm also effect this result, that the amount of water which can be drawn through the water-supply or pipe after it has been thrown out of action by accidentl'or instance, if by the entrance of air in the suction-pipe or by a sudden jar the live steam is caused to escape through the overflows.

What- I claim as new, and desire to secure by Letters Patent, is-- 1. The combination,with the casing having the interior bridge,h,and the steam-nozzle F, having the valve-seat l, of the steam-cone H, having a stem extending into and loosely guided by the bridge and provided with an attached valve, I, a laterally-projecting headpiece, Z, secured to one side of the stem and provided with a slot, Z, the shaft Z having an cccentric-piml", engaging the slot in said head at one side of the stem, and a lever, J, connected with the shaft, substantially as described.

2. The combinatiomwith the casing having the interior bridge, 71?, and the stcamnozzle F, having a valve-seat,l,ot' a steam-cone, H, having a sectional stem, the lower section provided with a valve, I, and the upper section loosely guided in the bridge, the head-piece L,

secured to one side of the stem and provided with the slot Z,the shaft-Zflhaving an eccentricpin, Z, engaging the slot in the head-piece at one side of the stem, and a lever, J, connected with the shaft, substantially as described.

3. The combination,with the casing and the steam-nozzle F, having avalve-seat, l, of the steam-cone H, having a valve-stem composed of two sections, the lower one having an at tached valve, I, the head-piece Z, arranged at one side of the stem and having the slot Z,the screw 2', connecting the stem-sections and attaehing the head-piece, the shaft Z, having an eccentric-pin engaging the slot in the headpiece at one side of the stem, and a lever, J, connected with the shaft, substantially as described.

4. The combinatiomwiththecasingA,ofthe steam-nozzleEthe steam-cone H, and valve I thereof, means for adjusting the steam-cone, the combining-nozzle G,the overflow-chamber surrounding the same, the overflow-orifices communicating with said chamber, the diaphragm M, extending obliquely across said cham her, and the overflow-nozzles and valves, substantially as shown and described.

In testimony whereofI havehereunto set my hand in the presence of two subscribing wit.- nesses.

OTTO XVESTPHAL.
