UNITED STATES PATENT OFFICE.
OTTO LEVENE IIALLBEOK, OF IVEST SALEM, ILLINOIS.
INJECTOR.
SPECIFICATION forming part of Letters Patent NO. 450,935, dated April 21, 1891.
Application filed September 25, 1890. Serial No. 366,126. (No model.)
T0 @ZZ whom z' may concern:
Be it known that I, OTTO LEvENE IIALL- BECK, a citizen of the United States, residing at IVest Salem, in the county of Edwards and State of Illinois, have invented certain new and useful Improvements in Injectors, of which the following is a specification.
My invention relates to injectors, and particularly to the class of automatic injectors which employ a central delivery-tube.
The object of the invention is to prevent the usual wear on the delivery-tubes occasioned by the pressure and velocity of the water as it passes through said tubes.
The invention consists in constructing a plate or washei` of some metal harder than the metal of the delivery-tube and inserting it in the said tube at the delivery-opening.
In the accompanyingdrawings, making part of this application, Figure l shows an injector in section with my plate in position. Fig. 2 is a cross-section of the delivery-tube, taken 011 the line 00, Fig. l, showing the plate in plain View. Fig. 3 is a detached perspective View of the plate. Fig. 4 shows a deliverytube made in sections, showing a modified form of the plate in cross-section; and Fig. 5 is a detached top view of such modification.
A represents the tail-pipe connection, I3 the steam-jet, O the overow-valve, and D the delivery-tube, of an injector.
As shown by Fig. l, the delivery-tube D has a cut-out E, which extends into the tube-opening and forms a vent for the delivery-tube. The tube-opening at this cut-out E is necessarily the smallest water-channel in the inachine, and therefore a greater wear on the metal of the delivery-tube is occasioned by the pressure and increased velocity of the water at this point, which makes the tubeopening larger and renders the delivery-tube unfit for its work and entirely useless.
To obviate the foregoing difficulties and to have the delivery-opening ot the tube E always the same size, a plate F, having a central aperture G, is placed at the said opening of the delivery-tube. This plate F, which I term a baffle-plate, is iliade or some metal harder than the metal ot the delivery-tube preferably of steel, (as the delivery-tube is usually made of brass) with beveled sides, so as to fit tightly in a groove II, formed across the tube-opening` at the cut-out E, having the aperture G in the baiiie-plate F, which is of the same size as the delivery-tube opening directly over the tube-opening.
Referring to the modifications shown by Figs. et and 5, the delivery-tube is made in two sections having screw-threaded connection, and the bathe-plate F is lnade in the form of a washer and is inserted into the female portion I of the delivery-tube, the male portion L of the said tube being screwed down on the bafiie-washer, so as to hold it firmly in place.
Instead of the cut-out E two vents fare bored or otherwise constructed at right angies to each other through the screw-threaded portion of the said tube above the washer E.
In either o the forms of tube hereinbefore described the baffle-plate or washer F can be readily removed and replaced if necessary, saving the expense of a delivery-tube.
l'Iavin g thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-
l. In an injector, the combination, with the delivery-tube, of a bathe-plate constructed of harder metal than the said tube and having an aperture the same size as the deliveryopening of such tube, substantially as shown and described, and for the purpose set forth.
2. In an injector, the co1nbination,\vith the delivery-tube grooved across its delivery-opening, of a baiiie-plate havinga central aperture and located in said groove, so as to protect the said opening, substantially as shown and described.
In witness whereof I hereunto set my hand in the presence of two witnesses.
