Abstract: My invention relates, principally, to that class of injectors in which the water receives io successive impulses from two or more jets of steam arranged in the same axial line, the velocity of the water being continually accelerated without being diverted from its course until it has acquired the velocity requisite to enable it to enter the boiler, but is also applicable to injectors having but one steam jet under suitable conditions. It is an object of my present invention to make an injector which shall be automatic in its action under variable conditions of water- supply and steam-pressure. and that shall be capable of restarting itself if from any cause the jet should be broken as soon as the disturbing cause is removed; and to this end my invention consists in providing an injector with a forcing combining-tube and a water-chamber provided with a water-inlet port and an over- flow-port which communicates with the atmosphere, which chamber contains the receiving and overflow openings of this combining-tube, in combination with a forcing steam-nozzle which terminates forward of the receiving end of the combining-tube; and it further consists in an annular lifting steam- nozzle, an annular lifting combining-tube, a central forcing steam-nozzle, and a forcing combining-tube, the discharging and of the forcing steam-nozzle being forward of the lifting combining-tube; and it further consists in an annular lifting steam-nozzle, an annular lifting combining-tube, a central forcing steam-nozzle, and a forcing combining- tube, the discharging end of the forcing steam- nozzle being forward of the receiving end of the forcing combining-tube; and it further consists in an annular lifting steam-nozzle, an annular lifting combining-tube, a central forcing steam-nozzle, a forcing combining-tube provided with a forward overflow-opening, a rear overflow-opening located at a point in the rear of that where the diameter of the, tube contracts to less than nine-tenths that of the discharging end of the steam-nozzle, with one or more intermediate overflow-openings, and an overflow-chamber in which all the overflow-openings are located. Claim: A forcing combining-tube and a water-chamber provided with a water-inlet port opening into and an overflow-port opening out of said chamber, which chamber contains the receiving and overflow openings of this combining-tube, in combination with a forcing steam-nozzle which terminates forward of the receiving end of the combining-tube.

Abstract: My invention relates to that form of injector in which the receiving end of the combining tube, and one or more of its additional openings, are contained in one chamber, and the description which follows will apply especially to that type in which two jets of steam or other actuating fluid are placed in the same axial line, so that the velocity of the water or other liquid may be constantly accelerated until it has acquired sufficient velocity to enter the boiler. All injectors in which the nozzles are fixed o and the areas of steam discharge and of water entrance to the combining tube are constant, have a steam pressure which is hereinafter called the limiting steam pressure, at which the maximum quantity of water will be delivered to the boiler, and above which, n- der the same conditions of water supply pressure and temperature, the capacity will decrease as the steam pressure is raised. During the operation of an injector, the absolute o pressure within the upper part of the combining tube where the steam jet comes in contact with the cold water supply, is always lower than the pressure in the supply chamber, owing to the partial vacuum caused by the condensation of the steam, and it is this difference in pressure which causes the snpply water to flow into the receiving end of the combining tube. As the area of this opening into the combining tube is constant, and the o difference in pressure is at its maxim um when the limiting steam pressure is reached, any increase in the weight of steam discharged, due to a rise in the steam pressure, will not be met by a corresponding increase of the inflow of the supply water to the combining tube, but, on the contrary, the less complete condensation of the steam in the upper part of this tube will reduce the difference in pressure and the inflow of feed will be lessened. Whenever an insufficient supply of water is provided, immediate condensation of the steam is not effected within the combining tube, and the low internal pressure will be communicated to and maintained in the surrounding overflow chamber, if provided with a suitable valve against the admission of air. The limiting steam pressure in the form of injector to which my invention chiefly ap- plies, and which is shown and described in United States Patent No. 376,315, granted to me January 10, 1887, is higher than that of other forms of injectors having fixed areas of admission, because its action depends upon certain relations which are nonexistent in other types. In the form of injector to which reference is made, the two actuating jets are placed in the same axial line and the combining tube of the lifting set discharges directly into the receiving end of the forcing combining tube. The capacity of this injector is much greater than that of its lifting set alone, owing to the fact that when the two sets are working in conjunction, the pressure within the receiving end of the forcing combining tube is reduced considerably below that of the atmosphere by the condensation of the forcing steam jet. These conditions obtain as the steam pressure rises, until the increased discharge from the forcing steam nozzle requires a greater supply of water than the lifting set can force through the fixed area of admission of the receiving end of the forcing combining tube, when the jet in this tube, while passing the apertures which open into the overflow chamber, will produce a partial vacuum at those points, and consequently also in the overflow chamber. Some of the water from the lifting set will then be diverted by this partial vacuum from the receiving end of the forcing combining tube into the overflow chamber, through the opening between the combining tubes of the lifting and the forcing sets, and will submerge the apertures in this forcing tube. The jet in this tube will 95 then draw this water in the overflow chamber into the combining tube through its submerged apertures and carry it into the delivery tube, thus materially increasing the capacity of the injector. These conditions obtain as the steam pressure rises, until the larger area of the lifting combining tube is just sufficient to supply the additional amount of water necessary for the condensation of the increased steam discharge, when the limiting steam pressure of this form of injector is reached, because the jet in the forcing combining tube requires for any increase in the steam pressure, an additional supply of water, which heretofore could not be provided without interfering with the satisfactory performance of the lifting nozzles at the lower pressures it is frequently desirable to use. Claim: An injector in which the actuating steam is divided into two or more jets and includes an overflow chamber which contains the receiving end and one or more apertures of a forcing combining tube, an outlet port to the r; air, and a supplemental inlet port from the water supply.

Manufactured by William Sellers & Co. - Philadelphia PA
Assigned to William Sellers & Co. - Philadelphia PA

Abstract: All injectors have an overflow opening from the nozzles through which an escape of water takes place until the jet has acquired sufficient velocity to enter the boiler, and whenever a casing is employed to maintain the nozzles of the instrument in proper relation with each other, this overflow opening forms a part of this casing, or is rigidly attached thereto. In all injectors which are adapted to restart themselves, when from any cause the jet is broken, the overflow passage must be very large as compared with those which are manipulated to restart, and it frequently o occurs that in placing such injectors in the position they are required to occupy for working, this fixed overflow passage is a serious inconvenience, so much so in fact, as to limit the position of the instrument. For example, lifting injectors are preferably employed upon locomotive engines, because they can be placed in the cab above the level of the water in the tank, and thereby avoid waste of water through the injector. In this position it is frequently desirable to place the instrument so that its discharging end shall be outside the cab, while the handles for manipulating it, shall be inside, but with a fixed overflow passage this is impossible, without cutting a hole through the cab large enough to admit this overflow passage, and when the injector is in place, this hole must remain open to permit the prompt removal of the instrument if required. The direction of the o overflow may require to be adjusted to the right or to the left, dependent upon which side of the locomotive it is placed, so that when two injectors are used on each locomotive, which is now the universal practice, the injectors must be inclined in opposite directions or the pipes which receive the overflows must be bent, either of which is very undesirable. The objects of my present invention therefore are, to provide short and direct overflow o passages of sufficient cross sectional area to permit automatic restarting and to arrange the overflow passage so that its relation to the instrument can be modified at will. To these ends my invention consists in an overflow chamber and a removable casing, which encircles this chamber, provided with a check valve to prevent the admission of air to the chamber, through which casing the overflow has exit, and it further consists in an overflow chamber provided with a check valve to prevent the admission of air to the chamber, and a removable casing which encircles the chamber and the check valve, through which casing the overflow has exit. Claim: In combination with an injector, a removable overflow casing which encircles the body of the injector and contains a passage for the overflow, between the overflow chamber of the injector and the air.

Abstract: The object of this invention is to produce an injector of plain construction, and capable of automatic action that will start in operation, lifting the water to itself, if necessary, simply upon the admission of steam, and without any further manipulation or adjustment of valves or cocks, which would require the attention of a skilled attendant, and also so arranged that if its action becomes interrupted it will readjust itself to its proper work again, and so continue as long as steam is supplied and there are no foreign substances to obstruct its operation. To accomplish this it is necessary to have one apparatus which will draw the water into the injector and deliver it with some force and great regularity to another apparatus that forces it to the place of final destination, and they must be so arranged and constructed that the second shall in no way at any time interfere with the first so as to prevent it from drawing the water into the injector, and also so that the second, when operating, shall receive the water delivered into the injector, by the operation of the first apparatus; and it tis also further necessary to provide a vent or outlet for the escape of the steam and water (luring the preliminary action of the injector without passing through the second apparatus, and to make the operation of the injector automatic this outlet must be fitted with a valve so arranged that it will close when the action of the injector is established and not before, and will remain closed so long as such action continues, but when such action is broken will open again to allow the injector to repeat the preliminary actions that go to produce its perfect working. Injectors have been made containing two sets of apparatus for the purpose indicated; but so far as I am aware their construction is such that when the injector has to lift its supply of water the second will not start in operation if steam is admitted-to both at the same time, it being necessary for the apparatus that draws the water into the injector to be first put in operation and the water made to cover the second apparatus before the latter is started. This renders it necessary to have separate valves for letting on the steam to each, and complicates both the construction and operation of the injector, and requires skilled attention and manipulation, which I obviate. I am also aware that single-jet injectors have been made in which a valve fitted to the vent or outlet, commonly called the " overflow", has been closed automatically; but in such cases it has been done in either one of two ways—first, by the inward suction of the injector that may sometimes be established at the overflow, owing to an insufficient supply of water, or other imperfections in the working of the injector; but such closing is only to prevent air entering, and does not in any way prevent the escape of water when it is present at that point ; second, by the pressure of the water in the injector upon the valve itself to close it when the steam thereof is released by the raising of the check-valve; but such valve must remain closed until the check- valve again presses it open, and as the pressure upon it must at all times, while steam is turned on the injector, be considerable, it will lose its automatic action unless the check-valve is carefully arranged to prevent any free escape of water around it, and it will then only regain it when the steam is turned off. In my invention the closing of the valve by the device herein shown prevents all ingress or egress of water or air at that point, and whenever the injector ceases to work there is nothing to prevent the check-valve returning to its seat, when all the pressure of the water or steam in the injector will press up)on the valve and its attachments to open it. Claim: In a steam-injector, a water-inlet port opening into and an overflow-port opening out of one and the same chamber.
