SPEGIFIGATION formingpart of Letters Potent No. 281,010, dated July 10, 1883.

Application filed May 15,' 1883. (No model) To all whom it nmy concern: Be it known that 1, WILLIAM W, Bnisnnn,

of Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Engine-Lnbricetors;

and I do hereby declare the following to be a: full, clear, and exact description of the inven- 1 brientors for sten-mengines; and it consists inf certain features of construction and in Ombl-- nation of parts hereinafter described, and;

vternel ports of the engine that requires lubripointed out in the claims.

In the drawing, the figure is an elevation, l partly in section, of s lubricntor embodying" 5 peeity for the size of the engine on which they are to operate, and the quantity of .oil dismy invention.

A represents an oil oonteiner, located preferahly bythevside of the engine-cylinder H,; and having at a an orifice provided with the strainer a, for filling the container with oil.

B is an oitpump, that may beineloscd in the container, and is provided with the usno l check-valves, b and 21'. Through the former the oil is received from the container into the pump, and through the latter the oil from the pump is forced into the pipe I)", that leads to the steam-pipe h of the enginecylinder.

O is e rod, one end of which forms the plunger ofthe pump, while the other end is attached to the piston c and forms the piston rod for the smell. pump-cylinder G. The piston c is suspended between the coiled springs (Z and oi, the former embracing the pistonrod and the latter attached to the lnmdsorew I),

by which the tension of the springs is reguleted.

E and l are pipes leading from their respective ends of the cylinder H to the cylinder 0', leading preferably through the con tniner A. These pipes connect the former with the top and the latter with the bottom of the cylinder C, and are provided with the valves 6 and e, and'nlso the valves 0 and e.

The operation ofthe device is as follows: The container A is filled with oil and'the valves are all opened. When steam is admitted to the righthn-nd end of the cylinder H, it will pass through the pipe E and into the pump cylinder (3, under the piston c, and raise the piston, togethen'with the attached rod (1, which is, as aforesaid, also the pumppl 11 11 ger. When the, engine reverses and steam is in the left hend end of the cylinderH, it will pass through the pipe E and into the top of the pump-cylinderG, and press the piston edownward. In the meantime the steam from under the piston c will have been lexheusted with the stemn from the. right-hand end of the cylinder H. Thus everystrokc of the engine will cause a stroke of the pump B. By the action of the pump, oil will be drawn from the container A and forced into the steam-pipe It, when by the current of steam it is carried to all ofthe incntion. These oil-pumps and their attach ments are made, respectively, of suitable as charged may be still further regulated by ninnipnlation'of the parts, As the pump makes even strokes with the engine, the nnnmer of controlling the discharge of oil must be by controlling the length of the stroke of the pump.

By turning down the handserew D the stroke of the pump may be shortened as desired; also, the springs d and d, that act as cushions for the piston, more or less restrain the motion of the piston,- according lo the pressure of steam on the piston, and the springs are each of such stillness that the piston, with the full owor olthe stomn, will lull-t nil c m'nrcome the elasticity oi cilhor spring. 'llioro fore it less pressure ot steam will romprosslho springs less, and consequently lltl ii-ovate the piston less, or produces shorter stroke of the pump, than a l'ullpressure. This pressurcnniy be regulated at the will of the operator ll) throttling; the slenm l menus oi the YillHS and v. The result is llml :my disclmrgrol' oil that is less than the full (spur-it olillo pump may be had as desired; also, when m opp-nrntus has been :ul jusled so than llw pump will furnish the required nmounl ol' llllllltillll per hour to supply llw \nmls oi the engine, the supply will still vary more or less, according:

to the lozul llml the engine curries from time to time.

IOO

This same'change in the pressure of the steam will be had in the cylinder and will vary the stroke of the pump, so that the engine,

as shown, a trap is formed that soon fills with water, which, by its own gravity, remains in the pipes and is not exhausted with the strokes of theengine. Therefore very little steam is required to operate the pump.

When by means of the condensation the parts are filled or partially filled with water,

I 5 as aforesaid, the steam p'resses'alternately on the pipes Eand E, and the water in turn presses upon ,and actuates the piston c.

-'F here are two advantages in thus operating the pistonby water: First, economy of steam. The quantity of 1 steam that would be required to actuate the piston 0 without any water in the apparatus,

as is the case in starting, will, by means of the trap and condensed water, be lessened by whatever amount-of water is left in the apparatus from the last preceding stroke, as it'is evident that steam will not be required to fill pipes, &c., that are already filled with water. Second, the long-continued action of the hot steam on the springs is injurious to them, whereas, by the intervention of water between the steam and the piston and springs, the springs will retain their elasticity much longer.

In cases when, from local causes, it is im- 3 5 practicable to set the apparatus low enough to form a trap, the device may be used with steam alone, as first described, and the springs re- '7 newed when required.

What I claim isl 1. In an oil-pumpfor lubricating, the com.- 4o

bination, with a pump-cylinder connected with a power-cylinder having'devices for admitting and controlling the action of the motive agent upon its piston, of an oil-container having a pump and discharge-pipe, and the valves for 5 admitting and discharging the oil therefrom into the power-cylinder, the, said pump-cylin der being adapted to operate the pump, substantially as shown.

2. In an oil-pump 'for lubricating, the combination, with its pump-cylinder, having pipes connecting itsrespective ends of the powercylinder, valves for regulating the, admission of the motive agent, anda piston provided with yielding devices to regulate the action of the motive agent thereon, of the oil container, having a discharge-pipe provided with valves, and apump whose plunger forms part of the piston rod, substantially as shown and described. 6o

3. In an oi1-pump for lubricating, the combination, with the pump-cylinder and its cylinder, of the springslocated on "each side of the piston, for regulating the action of the motive agent and governing the stroke of the said. piston, and the screw or devices for regulating the tension of the springs, substantially 'as shown and describe 'In testimony whereof I sign this specification, in the presence of two witnesses, this 2d day of. May, 1883.
