UNITED STATES PATENT OEEICE.
GEORGE B. BE'AYTON, OF BOSTON, MASSACHUSETTS.
IMPROVED OIL-INJECTOR FOR STEAM-ENGINES.
Specification forming part of Letters Patent No. 57,079, dated August 14,1866; antedated July 30, 1866.
To all whom t 'may concern:
Be it known that I, GEORGE B. BRAY'roN, of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improved Oil-Injector for Steam-Engines; and I do hereby declare that the following, when taken in connection with the drawing which accompanies and forms part of this specification, is a description of my invention suflicient to enable those skilled in the art to practice it.
The invention relates to that class of lubrieators for steam-engines in which a pump is used in connection with the oil-containing reservoir, the barrel of the pump being irst illed in the reservoir, and then brought into position to eject its contents into the steam tube or passage leading tothe steam-chest or parts to be lubricated.
The improvement consists in so construct- 1 ing the instrument that the orifice through which the barrel is alternately charged in the .eer-voir and discharged in the steam-chamber works through a compressed packing, by i. nich means communication between the reservoir and steam-chamber, excepting through the pump, is not only cutoff, but in such manner that the parts may be kept perfectly' tight and free from -all liability to leakage of steam.
The drawing represent-s a central section of an instrument embodying my invention.
a denotes the oil-reservoir. having a screw at its lower end, by which it is applied to the tube b, leading` to the steam-chest or parts to be lubricated In thisA reservoir is the ol` pump, the barrel c of which has a piston, d, working in it, and an orifice or passage, e, at its lower end, through which, by the action of the piston, the barrel is alternately filled and discharged. l
Thebarrel c extends down through a metal disk, e, forming the bottom of the chamber,
andthrough the top of the tube d, as seen Vin the drawing. It also extends through the cap j' of the reservoir, and has a hand-Wheel, g, at top, by which it may be forced from the position seen in the drawing (in which position it is held normally by the pressure of the steam against the lower end of the barrel or a stem, h, extending down therefrom) down through the reservoir and into the tube b u'ntil the oritice of the oil-passage c `is brought into the chamber of the tube b.
To prevent leakage of steam past the barrel into the oil-reservoir, packing 'i is placed between the top of the tube b and the disk e, said packing being compressed between the disk and the tube by the screw-threads by which the reservoir and tube are connected, this compression of the packing eifectually preventing escape of steam into the reservoir.
It will be obvious that the stuffing-box may be readily repaired, whenever necessary, by removing the reservoir from thel tube.
In operating the injector, the piston d is first drawn up, .the oil rushing in through the passage e and filling the barrel. The barrel is then forced down until the orice e opens into the tube, when by forcing down the piston the oil will be injected into the steamchamber.
I claim- The construction by which the oil-orifice of the injecting-barrel is worked through a packing inserted and compressed between the reservoir and steam-tube, substantially as set forth.
In Witness whereotI I have hereunto set my hand` this 6th day of December, A. D. 1865.
Y GEO. B. BRAYTON.
