ANDREWMORRISSON, OF COLEMAN, TEXAS.
WINDMILL.
SPECIFICATION forming part of Letters Patent No. 724,914, dated April .7, 1903.
Application filed November 25, 1902, Serial No, 132,769. (No model.).To all whom it may concern:.
Be it known that I,-ANDREW.MORRISSON, a
citizen of the United States, residing at Cole-
man, in the county of"Coleman and State of
5 Texas, have invented new and useful Im-
provements-in Windmills, of which the fol-
lowing is a specification.
My'invention relates to new: and useful im-
provements in windmills, and more particu-
io lady to the mechanism'for transmitting mo-
tion from the wheel-shaft to the pump-rods.
Objects of the invention are to provide
means whereby a double stroke of the rods
may be obtained during one revolution of the
15 shaft and to employ a novel connection be-
tween said rods and the shaft.'.
With the above-and other objects in view
the invention consists in the novel construc-
tion and combinationof parts hereinafter
20 more fully described and claimed, and illus-
trated in the accompanying drawings, show-
ing the preferred form of my invention, and
in which-
Figure 1 is a perspective view of a portion
25 of a windmill embodying my improvements.
Fig. 2 is an enlarged section through the mill-
head, showing the connections between the
shaft and pump-rods; and Fig. 3 is a similar
view of a modification, one ofthe connecting-
30 sleeves being shown ini elevation-
Referring to the figures by numerals of ref-
erence, 1 is a derrick of suitable construe-
tion, upon which is pivotally mounted a mill-
head 2, having a vane 3 and a wind-wheel 4
35 thereon. An auxiliary vane 3", having a
weight 3b connected thereto, is arranged upon
the head 2, and the same, together with vane
3, is adapted to be operated. by a lever 4",
mounted upon the shaft.4b of vane 3. A cord
40 4C extends from the levr, whereby the same
may be moved by a person at the base of the
derrick. The shaft 5 of this wheel is prefer-
ably provided with tWO oppositely-extending
cranks 6, arranged above the vertical passage
45 7, formed in the head 2, and each connected
to a pitman 8. The bottom of the passage 7
is closed by a disk 8a, having a central aper-
ture 9, within which 'is-slidably mountedd a
tube 10, held in a vertical position by a pend-
5o ant 11, within which the tube is mounted.
A flange 12 is formed at the upper end of this
tube, and it is connected to one crank 6 by'apitman 13. The other, crank' on shaft 5 is
connected by a pitman'8 to a head 14, formed
at the upper end of a rod 15, and this rod is 55
slidably mounted within and extends through
the sleeve 10.
A disk 16 is arranged at the lower end of
tube 10 and provided in its lower face with a
circular recess 17. This recess is adapted to 6o
receive the upper end of a pump-rod 18, and
the rod is held in position thei'ein by means
of a .sleeve 19, bolted or 'otherwise secured
thereto. The sleeve is secured to the rod at
a distance from the end 'thereof equal to the 65
depth of recess 17, and an L-shaped arm 20
extends laterally from the end of the sleeve
and is formed integral with the plate 21,which
extends over and is slidably mounted upon a
flange 22, inclosing the disk.16. This arm 20 70
serves to hold'the end of the rod 18 at all times
within the recess 17 and at' the same time per-
mits the disk to revolve without necessarily
moving the rod 18 out of vertical position. A
similar but smaller disk 23 is formed at the 75
lower end of the rod 15, and this is also pro-
vided with a recess 24 in its lower face, which
receives the end of a second pump-rod 25.
The flange 26, inclosing the disk 23, projects
under a plate 27, 'similar to but smaller than 8o
the plate 21 and fornied integral with an L-
shaped arm" 28, projectingrlaterally from a
sleeve 29, detachably secured to the rod 25.
In Fig. 3 I have shown a modified form of
mechanism for. transmitting motion from the 85
wheel-shaft to the pump-rods. In this modi-
fication I have"substituted gear-wheels for
the cranks 6. "Two gears 30 are secured to
the shaft 5 and mesh with larger gears 31,
each of which is provided.upon its inner face 90
with a wrist-pin 32, engaging one of the pit-
men 8. These pins are arranged so as to
lower the pitnien' alternately. By this con-
struction of windmill it will be seen that one
downward stroke of. each pump-rod, or, in 95
other words, a total of two downward strokes,
is secured during each revolution of the
wheel-shaft 5; also, as the mill.- head re-
volves upon the derrick 1 the pump-rods will
remain in their ordinary. upright positions, too
while the disks 16 and 27 revolve within the
arms of the sleeves connected thereto. As
.these sleeves are detachably secured to the
rods, said rods can be quickly placed in po-
