UNITED STATES PATENT OFFICE
DAVID WISE, OF COTTONDALE, TEXAS.
MECHANICAL POWER.
SPECIFICATION forming part of Letters Patent'No. 300,425, dated June 17, 1884.
Application filed April 10, 1884. (No model.)To all wl7onz, it may concer:
Be it knowfi that I, DAVID WISE, a citizen
of the United States, residing at Cottondale,
in the county of Wise and State of Texas, have
5 invented a new and useful Mechanical Power,
of which the following is a specification; ref-
erence being had to the accompanying draw-
ings.
This invention has relation to mechanical
io powers designed for running light machinery-
such as well-pumps, churns, sewing-machines,
washing-machines, &c.; and it consists in the
construction and novel arrangement of parts,
as will be hereinafter fully described, and par-
1r ticularly pointed out in the claims.
Figure 1 is a side elevation taken from the
side on which the gear-wheels are mounted.
Fig. 2 is a sectional detail view of one of the ad-
justable boxes, its guides, spring, lever, and
20 wedge for holding it in the out-oY-gear posi-
tion. Fig. 3 is an elevation of the opposite
side of the machine. Fig. 4 is a horizontal
sectional view on the line x x in Fig. 1. Fig.
5 is a sectional detail view of the brake mech-
25 anism applied to the intermediate shaft. Fig.
6 is a vertical longitudinal sectional view on
the line y y in Fig. 4, but showing the full
height of the machine; and Fig. 7 is a per-
spective detail view. of one of the pulleys and
30 its holder, over which the spring - actuated
cords run.
Referring by letter to the accompanying
drawings, a designates the frame of the ma-
chine, which is provided with two complete
35 motors, which are arranged in the frame to
operate independently or in conjunction to
drive the same shaft to impart power to the
machinery that is to be operated; and as the
motors are alike in construction, a description
40 of one will suffice for both in many particu-
lars.
b and b' designate the side beams interme-
diate of the top and bottom of the frame, which
are provided with the boxes in which the three
45 transverse horizontal shafts c, d, and e are jour-
naled. The shaftsc and eare provided at one
end with gear-wheels c' and e',which, when the
machine is in gear, mesh with a pinion, d', on
the end of the intermediate shaft, d. The
50 gear-wheels c' and e' are provided with spring-
pawls c' and e, which engage ratchet-wheels
c' c' on their respective shafts inside of thesaid wheels. Pivoted detents f are also ar-
ranged at this side of the frame, and are
adapted to engage the ratchet -wheels c4 c, 55
which are fixed to the shafts c and e, and pre-
vent them from turning backward. At the
middles of the shafts c and e drums h are
keyed, in order that they may revolve with
the said shafts, and on these drums the oper- 6o
ating-cords A' h' are wound. The boxes i for
the shafts c and e are made adjustable longi-
tudinally of the rail b' in guides i' i, secured
to said rail b', and are held in their normal
positions-i. e., in gear-by springs i, let 65
into recesses in the shoulders k of the rails, and
also into recesses 'Y in the outer ends of said
boxes. The shoulders k', or inner shoulders
on the rail b', are kerfed vertically and longi-
tudinally for short distances, and in these kerfs 70
levers 1 are fulerumed, and are used to throw
the motors out of gear with the pinion d',when
desired. Wedges ' are inserted in the spaces
formed by shifting the boxes outwardly to hold
the motor out of gear for any desired length 75
of time. When the wedges are withdrawn,
the springs return the boxes to their normal
positions. The opposite ends ofthe shafts c and
e are made rectangular, to receive the crank-
handle by which the cord is wound upon its 80
drum. The railbatthisside of the frameis pro-
vided on its inner face with the brake.mechan-
ism, by which the speed of the motor or mo-
tors, as the case may be, is regulated; and this
mechanism consists of a half-box, in, fixed to 85
the rail b and a half-box, mn', secured over the
shaft d to the top of the half-box in by a bolt,
n, threaded only at its lower end, and work-
ing in a threaded seat in the half-box mn, the
opening in the half-box m' through which it go
passes not being threaded. The holes at the
other ends of these half-boxes m im' are simi-
larly constructed; but in these openings, in-
stead of a simple bolt, a shouldered lever-
screw, o, is provided, its lower end only being 95
threaded, the shoulder resting on the top of
the half-box m', and the cross-head o' being
adapted to be grasped by both hands, and the
lever-screw turned to force the upper half-
block m' down upon the shaft d, thereby caus- o
ing it to serve as a brake to regulate the speed
of the motors. At this end of the shaft d a
chain-wheel is provided, over which the chain
from a pump may run to pump water from a
