CLYVE DOLPHIN HELM, OF FORT WORTH, TEXAS.
LUBRICATOR FOR ECCENTRICS.Specification of Letters Patent. - Patented April 21, 1908.
Application filed August 28, 1907. Serial No. 290,538.To all whom it may concern:
Be it known that I, CLYVE DOLPHIN
HELM, a citizen of the United States, resid-
ing at Fort Worth, in the county of Tarrant
5 and State of Texas, have invented a new and
useful Lubricator for Eccentrics, of which
the following is a specification.
This invention relates to eccentrics and
more particularly to means for applying a
10 lubricant to the eccentric and its associated
parts.
The object'of the invention is to provide
an eccentric including a sectional strap one
section of which is formed with an interior
15 chamber or reservoir adapted to contain a
quantity of oil or other lubricant which is
distributed over the surface of the eccentric
when the latter is rotated thereby to prevent
undue friction between the parts.
20 A further object is to provide means for
supplying oil to the lubricating chamber or
reservoir and means for regulating the dis-
charge of lubricant from said chamber.
A still further object of the invention is to
25 generally improve this class of devices so as
to increase their utility, durability and effi-
ciency.
Further objects and advantages will ap-
pear in the following description, it being
30 understood that various changes in form,
proportions and minor details of construc-
tion may be resorted to-within the scope of
the appended claims.
In the accompanying drawings forming a
35 part of this specification: Figure 1 is a side
elevation of an eccentric provided with a
lubricating device'constructed in accordance
with my invention. Fig. 2 is a vertical sec-
tional view taken on the line 2-2 of Fig. 1.
40 Similar numerals of reference indicate
corresponding parts in all of the figures of the
drawings.
The improved lubricating device may be
applied to the eccentrics of gas-engines, steam
45 engines or other machinery and by way of
illustration is shown in connection with an
eccentric of the ordinary construction in
which 5 designates the operating shaft and 6
the eccentric plate or disk.
50 Surrounding the disk or eccentric 6 is a
strap preferably formed in two sections 7 and
8, each provided with laterally extending
lugs 9 having perforations formed therein
for the reception of bolts or similar fastening
55 devices 10 whereby the sections of the strap
may be clamped in position on the disk 6.One of the sections 8 is secured to or
formed integral with the eccentric rod 11
while the opposite section is provided with a
lateral enlargement 12 having an interior 60
chamber or reservoir 13 formed therein and
adapted to contain a quantity of oil or other
lubricant, as shown.
The outer curved wall of the enlargement
12 is provided with an opening 14 through 65
which oil or other lubricant is introduced
into the reservoir 13, the walls of said open-
ing being threaded for engagement with the
correspondingly threaded walls of a cap or
plug 15 which latter serves to normally close 70
the reservoir and thus prevent the escape of
lubricant.
The inner faces of the sections 7 and 8 are
formed with a circumferential groove 16
adapted to receive the peripheral edge of the 75
disk 6 and formed in the wall of the groove
16 and communicating with the reservoir 13
is a threaded opening 17, there being a simi-
lar opening 18 formed in the outer curved
wall of the enlargement 12 and disposed in 80
alinement with the opening 17 for the recep-
tion of a feed tube 19.
The lower end of the feed tube 19 is re-
duced at 20 and provided with terminal
threads 21 for engagement with the threads of 85
the opening 17 when the tube is placed in
position on the strap section 7. The ex-
terior walls of the tube 19 at the upper end
thereof are perfectly smooth and unob-
structed for engagement with the corre- 90
spondingly smooth interior walls of the open-
ing 18, there being a rectangular head 22
formed on the upper end of the tube so that
the latter may be conveniently grasped with
a wrench or other suitable tool when posi- 95
tioning the tube within the oil receiving
reservoir. The interior walls of the tube
at the upper end thereof are threaded at 23
for engagement with the correspondingly
threaded exterior walls of a cap or feeding 100
device 24, the latter being provided with a
plurality of feed apertures 25 adapted to
register with corresponding feed. apertures
26 formed in the tube 19 thereby to permit
the oil or other lubricant in the reservoir to 105
flow through the tube and lubricate the ec-
centric and its associated parts.
Arranged within the tube 19 and cap 24 is
a quantity of felt, cotton, vegetable fiber or
other absorbent material 27 which becomes 110
saturated with oil from the reservoir 13 and
1 which serves to uniformly distribute theNo. 885,046.
