JAMES S. SLOVER, OF LUBBOCK, TEXAS.
PUMP AND WINDMILL CONNECTION.Specification of Letters Patent. Patented July22, 1913.
Application filed October 12, 1912. Serial No. 725,464.To all whom, it may concern:
Be it known that I, JAMEs S. SLovER, a
citizen of the United States, residing at
Lubbock, in the county of Lubbock and
5 State of Texas, have invented certain new
and useful Improvements in Pump and
Windmill Connections; and I do hereby de-
clare the following to be a full, clear, and
exact description of the invention, such as
10 will enable others skilled in the art to which
it appertains to make and use the same.
This invention relates to power transmis-
sion mechanisms, and it more particularly
relates to a pump and wind mill connection.
15 An object of the invention is to vary the
relative strokes of the driving rod and the
pump plunger rod.
Another object of the invention is to ac-
celerate and retard the motion of the pump
20 plunger rod.
A further object of the invention is to
provide an adjustable device of this char-
acter which may be easily and properly ap-
plied to pumps and wind mills of different
25 kinds.
A still further object of the invention is
to provide a device of this character which
may be applied to a pump and wind mill
without materially altering or changing the
30 position of any of the principal elements of
said pump or wind mill.
Other objects and advantages may be re-
cited hereinafter and in the claims.
In the accompanying drawings which sup-
35 plement the following specification, Figure
1 is a side elevation view of a pump having
my improved transmission mechanism at-
tached thereto and to a wind mill of ordi-
nary construction, only a fragmental ele-
40 meant of the latter being shown, and, Fig. 2
is a horizontal sectional view taken on the
line 2-2 of Fig. 1.
Referring to these drawings, in which
similar reference numerals correspond with
45 similar parts throughout the several views,
the pump stock is designated by the numeral
5, the numeral 6 designating the plunger
rod of the pump. To the driver rod 7, of
the wind mill, is connected a driver link 8
50 which is pivoted at 9 to the lower substan-
tially horizontal lever 10, the latter being
pivoted at 11 to an oblique standard 12
which is secured on the platform 13, which
covers the well and supports the pump
55 stock.At one end of the lever 10 is pivotally
connected the lower link 14, the pivotal con-
nection being indicated at 15, the upper end
of the link 14 being pivotally connected at
16 to an oblique lever 17 while the latter is 60
pivoted at 18 to the standard 12. The up-
per end of the lever 17 is pivoted at 19 to
the upper link 20, the latter being pivoted
at 21 to the upper horizontal lever 22. The
lever 22 is pivoted at 23 to the upper end 65
of the standard 12, one end of said lever 22
being pivotally connected at 24 to the plun-
ger rod 6. The arrangement of the several
links and levers is such as to produce the
greatest increase of power, consistent with 70
compactness, for raising the plunger 6, and
this arrangement is made possible by the
employment of the oblique standard which
is inclined upward in the direction of the
pump plunger rod. It will be noted that 75
the pivotal point 23 is considerably nearer
to the pivot 24 than it is to the pivot 21. In
other words, considering the lever 22 as com-
prising two sections on the right and left,
respectively, of the pivot 23, the left section 80
is about two-fifths of the entire length of the
lever. The lower lever 10 has its pivotal
point near the center, but slightly offset
therefrom, so that the left-hand section is
longer than the right-hand section, consid- 85
ring the pivotal point 11 as dividing this
lever into two sections.
Where a pump is connected with a wind
mill in the usual way, the rods 6 and 7 are
in substantially vertical alinement, and one 90
or both rods are extended or supplemented
by a suitable connecting link for securing
them together. However, in attaching the
transmission mechanism of this character, it
becomes necessary to deflect the rod 7 95
slightly out of vertical alinement with the
rod 6, so that the pump stock 5 will not in-
terfere with the vertical movement of the
driver link 8. Therefore, the lever 22 is ex-
tended laterally beyond the link 8, so as to 100
overhang the end of the lever 10 and to
bring its pivotally connected end directly
over the center of the pump stock.
In order to compensate for the weight of
the members 6, 7 and 8, a weight. 25 is pro- 105
vided near the end of the lever 10, opposite
to the end which supports the link 8, and
said weight 25 is slidably momuted on the
lever 10 and adapted to be adjusted in either
of several alternate positions by means of a 1101,067,848.
