ELIAS H. COWAN, OF OAKALLA, TEXAS, ASSIGNOR OF ONE-HALF TO HARVEY
M. RAMSOWER, OF SAME PLACE.
WELL-CLEANING MACHINE.
SPECIFICATION forming part of Letters Patent No. 647,947, dated April 24, 1900.
Application filed November 29, 1898. Serial No. 697,790, (No model)To a7li whom it imhay conicer n:
Be it known that I, ELIAS H. COWAN, a citi-
zen of the United States, residing at Oakalla,
in the county of Burnet and State of Texas,
5 have invented a new and useful Well-Clean-
ing Machine, of which the following is a speci-
fication.
My invention relates to well-drilling ma-
chinery, and particularly to a well-cleaning
10 machine adapted for farm and general use
and designed to facilitate the cleaning of wells
which have become more or less obstructed
by accumulations or which require deepening
to increase the yield; and the objects in view
15 are to provide a simple and comparatively in-
expensive apparatus adapted to be mounted
upon a wagon-bed or other suitable truck for
transportation to and from the point of use,
said apparatus being provided with means
20 whereby accumulations in the bottom of the
well may be loosened and subsequently re-
moved, and, furthermore, to provide an ap-
paratus of the class described which may be
operated either manually or by horse or other
25 power.
Further objects and advantages of this in-
vention will appear in the following descrip-
tion, and the novel features thereof will be
particularly pointed out in the appended
30 claim.
In the drawings, Figure 1 is a perspective
view of a well-cleaning apparatus constructed
in accordance with my invention. Fig. 2 is
a vertical sectional view of the same. Fig. 3
35 is a partialhorizontal section. Fig. 4 is a de-
tail view of a portion of the oscillatory or
spudding arm. Fig. 5 is a detail view of the
drill-tool. Fig. 6 is a similar view of the bailer.
Similar reference characters indicate cor-
40 responding parts in all the figures of the draw-
ings.
The apparatus embodying my invention is
preferably erected upon a base 1 for support
upon the bed 2 of a wagon or similar vehicle,
45 as upon the bed of a farm-wagon between
the usual side standards 3, whereby the ap-
paratus may be substituted for the wagon-
body when desired. Rising from the base at
its rear end are uprights 4, connected by a
50 cross-piece 5 and secured against vibration
and displacement by suitably-inclined braces6, in bearings of which is mounted a guide-
shaft 7. Also rising from the base between.
the vertical planes of the standards 4 is a mast
8, provided at its upper end with a hoisting- 55
pulley 9, traversed by a cable 10, to one end
of which may be attached a drilling or loosen-
ing tool 11 (shown in Fig. 1) or a bailing-
bucket 12. (Shown in Fig. 2.)
Fixed to the shaft 7 is a terminally-flanged 6o
operating-drum 13, upon which is reeled an
operating-cable 14, and. loosely fitted upon
said shaft 7 is a terminally-flanged hoisting-
drum 15, upon which is reeled the hoisting-
cable 10. The hoisting-drum is adapted to 65
be locked upon the shaft to receive rotary
motion therefrom by means of a clutch mech-
anism, which in the construction illustrated
consists of spurs 16 for engagement with a
crank-arm 17, the relative arrangement of the 7o
parts being such that when the drum 15 is
moved axially toward the arm or cross-head
17 the spurs 16 will engage the same, and thus
provide for the desired communication of mo-
tion from the shaft to the drum, or vice versa. 75
The means whereby this axial shifting of the
drum 15 may be accomplished consists of a
shifting - lever 18, suitably fulcrumed upon
the frame and connected with a slide 19,which
is bifurcated at its inner end to form ears 20 8o
to engage the adjacent flange of the drum 15.
Also arranged in operative relation with the
drum 15 is a brake-lever 21, adapted for con-
tact with one of the drum-flanges when the
free end of the lever is elevated to retard the -85
rotary movement of said drum, as in lower-
ing tools or the bucket into the well.
The crank-arm 17 is preferably of looped
construction, and in operative relation there-
with is arranged the free end of an oscilla- 90
tory or spudding arm 22, hingedlyor pivotally
mounted at its rear end upon the mast 8 and
provided at an intermediate point with a rope-
hitch 23, with which the hoisting-cable may
have a running connection. 95
When a drill-tool is in use, as in loosening
the earth or other accumulations at the bot-
tom of a well, the hoisting-cable 10 is engaged
at an intermediate point with the hitch 23
and-thence -is extended rearwardly and en- zoo
gaged with a holding device consisting, for
instance, of fastening-pins 24, projecting lat-
