Improvements in Lubricators.
I, GRANT ULYSSES MERRILL, of 17, Clark Street, in the City of Paterson, County
of Passaic and State of New Jersey, U.S.A., Electrical Engineer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement;
-
The object of this invention is to provide an improved force feed lubricator
for machine bearings and especially those in which grease or other viscid
lubricants are used, whether said bearings are of the stationary or movable kind
or not.
The invention consists in the improved lubricator and in the combination and
arrangement of its various parts, substantially as will be hereinafter pointed out
and finally enibodied in the claims.
In the accompanying drawings illustrating my invention,
Fig. 1 is a side view of my improved lubricator, certain parts thereof being
broken away;
•
Fig. 2 is also a side view of my invention, viewed from another direction;
Fig. 3 is a vertical sectional view of my improved lubricator, presenting a
certain modification;
Fig. 4 is a top plan view of the invention; and,
"
Fig. 5 is a detail view of a certain modification of a portion of the invention.
In said drawings, a represents a cylindrical receptacle provided with heads b
and c, the former being screwed upon the upper end, and the latter being
secured by a flanged and threaded union d to the lower end, of said receptacle.
The lower head c is of conical shape and terminates in and communicates with
a threaded and integral securing nipple e, which is adapted to be connected to
the bearings. to be lubricated, a nut f which said nipple carries being adapted
to firmly unite the parts.
The upper head carries a yoke g having a central internally threaded open-
ing in which is screwed a divided bushing or split nut i, having a central
threaded opening; said yoke is screwed upon the head. The modification involved
in the construction shown in Fig. 3 resides in substituting a single-piece inter-
nally threaded bushing for the divided bushing i and in providing the same
with a milled head.
I is a feed-screw which penetrates the bushing and engages the internal thread-
ing thereof, said feed-screw having a longitudinal groove m engaged by a key n
in the bore of a gear-wheel o disposed between the head band the yoke. Said
feed-screw may be with or without an operating-knob p, as shown in the drawings.
The lower end of the feed-screw is loosely secured, by means of a nut q, to a
piston or plunger r.
s designates integral lugs projecting from the yoke and affording bearings
for a worm t engaging the gear-wheel o. Said worm carries a ratchet-wheel u,
and it also carries, loosely, a lever v in which is mounted a spring-actuated pawl w
adapted to engage the teeth of the ratchet-wheel. is a stop-pawl secured upon
the yoke and also engaging the teeth of the ratchet-wheel. A more delicate
engagement between the lever and the ratchet-wheel may be effected by providing
CD 077

page_text: two or more pawls, such as those,y; shown in Fig. 5. The lever may carry a
weight, so that, if the device is mounted on a movable part of the machine to be
lubricated, it may be actuated by the swinging motion of said lever, or said
lever may be directly connected to a moving part of the machine in case the
lubricator is stationarily mounted.
The movements of the lever are confined and rendered adjustable by set-
screws a¹, arranged in lugs 61, extending from a bracket that projects from the
receptacle a.
In operation, it will be seen tlint when the lever vis oscillated, engagement
between the same and the ratchet-wheel will be effected by the pawl (or pawls y)
so as to rotate said ratohet-wheel and consequently, through the worm, the gear-
wheel o. The key n of said gear-wheel, which engages the slot of the screw 1,
will turn the latter and feed it downwardly through the bushing, thus lowering
the piston and forcing out the lubricant. When it is necessary to re-fill the
receptacle, the head is screwed off and the bushing screwed out of the yoke,
whereupon; after filling the receptacle and preliminarily to re-placing the head,
said bushing may be either twirled down to its initial position near the base: of
the screw and again screwed into the yoke, or, if it is the form of a split nut, it
is detached from its position in the yoke and its engagement with the screw and
re-set, with the screw engaging it in its initial or elevated position.
'
In order to regulate the feed of my improved lubricator, it is only necessary
adjust the set-screws a³, as will be obvious..

"
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
!
1: In a lubricating device, the combination of a receptacle having a suitable
outlet, a piston in said. receptacle, a. removable cover for. said receptacle, a screw
penetrating said cover and connected to, the piston, sustaining means for said
screw operatively and disconnectively engaging the same, a gear arranged, above
and supported by said cover and also penetrated by and keyed, to said screw, and
a yoke spanning the cover and the gear, in approximate contact with the upper
surface of the latter and carrying said sustaining means, substantially as described.
2: In a lubricating device, the combination of a receptacle having a suitable
outlet, a piston, in said receptacle, a removable cover for said receptacle, a screw
penetrating, said cover and connected to the piston, a flanged split nut for, said
screw, operatively and disconnectively engaging the same, and gear arranged above
and supported by, said cover and, also penetrated by and keyed to, said screw; and
a yoke spanning the cover and the gear, in approximate contact with the upper
surface of the latter and carrying. said split nut, said split nut being, screwed into
the yoke, substantially, as described.
"
3In a lubricating device, the combination of a receptacle, having a suitable
outlet, a, piston in said receptacle, a removable cover for said receptacle, a screw
penetrating said cover and connected to the piston,, sustaining means for, said
scrow operatively and disconnectively engaging the same, a gear, arranged above
and supported by said cover and also penetrated by and keyed to said screw, a
yoke spanning the cover and the gear, in approximate contact with the upper
surface of the latter, and carrying said sustaining means, a worm engaging said
gear and journalled on the cover, a ratchet-wheel connected to said worm,.,and
a weighted lever pivotally connected to the cover and provided with a spring-
actuated "pawl engaging said ratchet-wheel, substantially as described.
