dov nwardly, as at 21, into the well, the well-
bucket (not shown) being secured to the lower
free end of the cable.
It will now be observed that the weight of
5 the bucket acts as a tension to keep all parts
of the cable taut and that by pulling down-
wardly upon the portion 20 the portion 21,1
which extends into the well, is drawn up-
wardly, thereby turning the drum by fric-
ic tional contact with the grooved flange there-
of and winding the portion 19 upon the drum.
Thus the cable portion 19, which would oth-
erwise be free and either drop into the well
or upon the ground, is conveniently and ef-
15 fectively wound or coiled upon the drum,
which automatically takes up all slack, and
the entire cable is maintained in a proper
taut condition. It will of course be under-
stood that the cable portions 19 and 21 en-
20 gage the drum from opposite the cable por-
tion 20, which is the hand-operated portion,
whereby a downward movement of the latter
results in an upward movement of the other
portions.
25 Should a chain be used instead of a rope,
the groove will be substituted by peripheral
teeth or spurs to take into the links of the
chain, as will be understood
To lower the bucket into the well,the brake-
30 handle is manipulated so that the frictional
contact of the brake-band is slightly less than
the weight of the bucket, whereby the drum
will be reversely rotated, thereby unwinding
the coiled portion of the cable, which passes
35 through the block or pulley, thence over the
grooved periphery of the drum, and finally
down into the well.
Any suitable means may be employed for
locking the brake-lever when the brake is ap-
40 plied to the drum
What is claimed is-
1. The combination with a drun, of a guide
fixed independently of the drum, and a cable
having one end connected to the drum, then
45 reeved through the guide, and then having its
free end portion passed around the drum, the
opposite portions of the cable being passed
around the drum in opposite directions.
2. The combination with a drum, of a cable
50 having its opposite portions applied in oppo-
site directions to the drum, one end of the ca-
ble being fixed to the drum, the opposite end
being free to pass over the drum, and a guidefixed independently of the drum and receiv-
ing the intermediate portion of the cable. 55
3. The combination with a support, and a
frame rising above the same, of a drum mount-
ed upon the frame, a pulley-block connected
to the support, and a cable having one end
secured tothe drumn, then passed downwardly 6o
and through the pulley - block, thence up-
wardly and over the drum, and finally extend-
ing freely downward therefrom, the opposite
portions of the cable being passed around the
drum in opposite directions 65
4 The combination with a supporting-
frame, of a windlass-drum mounted thereon,
and provided at one end with a brake-surface,
and at its opposite end with a cable-guide, a
guide located below the drum and in vertical 70
alinement with the cable-guide, a brake for
frictional eniageinent with the brake-surface,
a guard embracing the cable-guide, and a ca-
ble having one end secured to the dru m,t hence
passed downwardly and through the guide, 75
thence upwardly and over the guide of the
drum, and finally freely pendent therefrom,
the opposite portions of the cable being passed
around the drum in opposite directions
5. The combination with a support, and op- 8o
posite posts rising at opposite sides thereof,
of a cross-bar supported upon the posts, oppo-
site hangers pendent from the cross-bar, a
drum mounted in the hangers, and provided
at one end with a brake-flange, and at the op- 85
posite end with a grooved flange, a pulley-
block mounted upon the support, a band-
brake secured to the cross-bar and embracing
the brake-flange, means for operating the
brake-band, a bowed guide embracing the 90
grooved flange and secured to the cross-bar,
and a cable having one end secured to the
drum adjacent to the brake-flange thereof,
then passed downwardly and through the pul-
ley - block, thence upwardly and over the 95
grooved flange, and finally freely pendent
from the latter, the opposite portions of the
cable being passed around the drum in oppo-
site directions.
In testimony that I claim the foregoing as loo
niy own I have hereto affixed my signature in
the presence of two witnesses
