To all whom it may concern.'

Be it known that I, CHARLES W. MANZEL, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and'useful Tinprovement in Lubricating Apparatus, of which the following is a specification.

This invention relates to a force-feed lubricating apparatus designed more particularly for the steam-cylinders of locomotives; but the same is also applicable to other engines in which it is desirable to supply oil to different points from a common source.

The object of my invention is to provide a simple apparatus of this kind whichinsures a uniform distribution of the oil to a plurality of chest-plugs or similar lubricating devices connected with the same feed pipe or conduit.

In the accompanying drawings, consisting of three sheets, Figure l is a side elevation of the apparatus applied to a locomotive which is-sliown by dotted iines. Fig. 2 is an enlarged vertical section of the lubricator. Fig. 8 is a longitudinal section of the distributer. Fig. 4 is a horizontal section of one of the chest-plugs in line 4 4, Fig. 5. Fig. 5 is an enlarged vertical section of the same.

Similar letters of reference indicate corresponding parts throughout the several views.

A indicates a force-feed lubricator of any suitable construction, which is located in the cab when the apparatus is applied to a locomotive.

In the lubricator shown in the drawings,

Fig. 2, B is the oil-reservoir, C the cylinder of the force-pump located in the lower ortion of the reservoir, and C the pump-p unger, which may be reciprocated by any suitable or well-known actuating mechanism.

d dare check-valves located in the discharge-passage of the pump-cylinder, and E is the delivery-passage of the lubricator, connected with said discharge-passage and preferably containing a suitable stop-cock or con- Y trolling-valve F.

G indicates the chest-plugs of one of the steam-cylinders, the locomotive (shown by dotted lines in'Fig. 1 being of the superheated type in which each cylinder is provided with three of such plugs. h indicates the individual feed-pipes of these plugs, which are respectively' connected withthree discharge branches or nipples h of a manifold or distributer H, las shown in Figs. l and 3. The distributer also has an inlet branch or nipple screw-threaded collar or union g3.

h2, which is connected with the delivery-pas-A sage E of the lubricator, so that the several chest-plugs connected with the distributer are supplied by the same pump. Each of these chest-plugs is provided with a choke or constrictedpassage for effecting an equal disy tribution of the oil to the several plugs supplied by the same pump, and for this purpose ing the post and provided in its lower-end with a tapering socket g2, which receives the correspondingly-shaped upper end of the post. The post and the head are united by a The head has an axial oil-passage g4, provided at its lower end with a seat g5, against which a\ check-valve g6 is adapted to close. This valve has a grooved or winged stein 97, which eX- tends upwardly through an enlargement gf* of the oil-passage g, and the same is held against its seat by a spring i, applied to said stem and bearing at its lower end against the bottom of said enlargement and at its upper end against a nut or collar i', secured to the stem. .The valve g prevents the water of condensation from entering the feed-pipe 71, and also prevents loss or waste of the oil in the feedpipe when the locomotive is drifting or` at rest.

j indicates a choke-plug applied to the upper end of the head g and provided with a constricted central passage j', which is gradually contracted from the upper end to about the middle of the plug and then flared toward the lower end thereof, as shown in Fig. 5.

c indicates a hood or inlet-chamber surmounting the head g and inclosing the chokeplug This chamber is provided at 'its uper end with an inlet branch lc', to which the fiont end of the feed-pipe h is connected, and at one side thereof with a vent or vent-nipple l for the escape of the air in said feed-pipe and the chest-plug. The outer portion of the bore of this vent-nip le is enlarged to form an internal seat or shoulder Z, a ainst which the inner end of a screw-plug m iears, which normally closes the outer end of the reduced portion of said bore. duced at its inner 'end to leave an annular s ace m between the saine and the wall of the nipple andis provided with a longitudinal passage m2, which extends from its outer end nearly to its inner end and communicates This plug is re- IOO IIO

y plugs.

several chest-plugs connected therewith Iis checked or retarded in its 'passage through the plugs by thek constrictions in the choke- The surplus or portion of the' oil in each chest-plug which does not find a quick exit through the restricted passage of its chokelug 'y` exerts a back ressure upon the oil in t e distributer H an the feed-pipes hof the other chest-plugs which equalizes the pressure in all of the chest-plugs of the same eed-pipe, and thereby effects a uniform supply and distribution of oil to them. To pro'- duce this effect, the actuating means of the oil-pump should be of a character to impart quick and sudden impulses to the lunger, so as to drive the voil through the fee -pipes and into the chest-plugs with sufficient force and speed to produce such equalizingor` back pressure. An suitable operating mechanism which wifl produce that action of the plunger may be used for this purpose; but I prefer to emplo an. air-motor of the type com rising a cy inder and piston and valve mec anisin for alternately admitting the pressure fluid to opposite ends of the cyllnder, the motor being conveniently supplied from the usual pressure-tank ofthe air-brake apparatus.4 l

As the lubricant is uniformly supplied to a y number of chest-plugs by the same pump, the y necessity of-providing a separate pump for each plug is obviated, thus simplifying the construction of the apparatus, rendering it more compact, and reducing' its cost accordwith the delivery-passage of the pump, and a plurality of chest-plugsvor oil-posts connected with said distributer by individual feedpipes andv each chest-plug or oil-port provided with a feed-passage having a choke 'or `constricted portion, anda check-valve arranged in said passage and closing toward the corresponding feed-pipe, substantially as set forth.

In a lubricating apparatus, the combination of a reservoir, a ump supplied therefrom, a manifold or distributer connected with the delivery-passage of the pump, and a plurality of chest-plugs connected with said distributer andV each provided with a feedpassage, a check-valve arranged in the feedpassage of each chest-plug, and a choke-plug arranged in each of saidA passages above the corresponding check-valve, substantially as set forth. f
