ALONZO W. CRAM, OF LITCHFIELD, ILLINOIS.
Specification forming part of Letters Patent No. 135,091, dated January 21, 1873.
l. To all 'whom 'it may concern:
Be it known that I, ALONZO W. CRAM, of Litchfield, in the county of Montgomery and State of Illinois, have invented certain new and useful Improvements in Steam-Injectors, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing and the letters of referl erence marked -thereon making part of this specification, in which Figure lis a side view. Fig. 2 is a longitudinal sectional view.
The object of my invention is to provide an improved water feeder or elevator for the boilers of steam-engines and other purposes, and relates to that class of devices in which water and other liquids are raised from the well or supply-reservoir by means of a vacuum created in a close tube or cylinder through the action of a steam-jet. My improvement in the injector consists in using a series of steamjets instead of a single one, as is the ordinary practice, and in securing them in a tapering or cone-shaped siphon-tube instead of a tube of uniform diameter, as has heretofore invariably been the custom. This arrangement-of jets, in connection with a tube so formed as to be gradually tapering, so as to contract its orifice at its discharge-mouth, operates most admirably, as the vacuumspace is greatly increased and the power correspondingly multiplied, causing the water to flow with a greater velocity, and to have its volume so coinpressed by the tapering tube and its contracted mouth as to accelerate and intensify the force of its current. l An injector constructed on this principle, and as hereinafter more fully described, is equally applicable and operates with the saine eifectiveness in supplying and feeding air as it does in elevating and feeding water.
The construction'and operation of my invention are as follows:
lThe injector is constructed of any suitable material. Its main section A is cone-shaped or of a gradually-tapering form. The discharge-orifice B in a tube or cylinder thus constructed is necessarily contracted, leaving its diameter much less than that ofthe orifice or opening O, through which the water or other liquid enters fromathe well or supply-reservoir. In connection with the gradually-contracting pipe A, instead of using a single steam-jet, as has been the practice heretofore in inventions of this character, I employ two or more.
The device' illustrated in the accompanying drawing has three of these jets, a b c, distributed and inserted in the tube A at regular intervals. The form and arrangement of these jets are distinctly shown in Fig. 2; but I desire it understood that as there is nothing arbitrary in regard to the dimensions of the siphon or the angle of its taper, so thereis nothing arbitrary as lto the number of jets that shall be used, their exact relative position, or
their other precise arrangements, as all these are matters which measurably depend on circumstances connected with the use for which a particular or given injector is intended, and in some degree whether it is water or air that is desired to inject, and which ordinary mechanical skill will suggest.
In the drawing my improvement alone is illustrated, no connections with the supplypipe or the discharge being shown; but it is connected with a well or other pipe at the opening C by any of the ordinary means now in .general use, and so arranged as to feed the water through the oriiice B by the usual appliances now employed.
The operation is as follows: The siphon being duly connected with a suitable induct and discharge, ,and steam being applied to the jets a b c, each creates a vacuum in the pipe A by the expulsion of the air or other liquid. The first of thesev series of vacuums is created by the jet c being at or over the connection with the orifice C; the water or other liquid from the well or supply-reservoir instantly rises to lill it, and from which it is instantly drawn, and in a slightly-compressed state, to the vacuum created by the jet b, and in like manner forced and driven on by the action of the jet c, and from which it is discharged at the contracted orifice B. The ta pering pipes gradually compressing the Voljets7 a, b c, the whole being constructed and urne, and the jets in like manner multiplying arranged to operate substantially as described.
the force, not only impart velocity to the flow, In testimony whereof Ihave signed my name but intensity and power to the current when to this specification in the presence of two snbdischarged. seribing Witnesses.
What I claim as new7 and desire to secure ALONZO W. CRAM. by Letters'Patent of the United States, is Witnesses:
An injector consisting of the tapering or EDWIN JAMES, cone-shaped pipe A and e series of steam- Jos. T. K. PLANT.
