NOAH J. MILLER, OF COLLINSVILLE, TEXAS.
MECHANICAL MOTOR.
SPECIFICATION forming part of Letters Patent No. 228,098, dated 1ay 25, 1880.
Application fled January 180.io all whom it may concern:
Be it known that I, NOAit J. MILLER, of Co01-
linsville, in the county of Grayson and State
of Texas, have invented certain now and use-
S ful Improvements in Mechanical Motors; and
I do hereby declare that the followiug is a full,
clear, and exact description of the invention,
which will enable others skilled in the art to
which it appertains to make and use the same,
so reference being had to the accompanying
drawing, and to:the letters ofreference marked
thereon, which form a part of this specifica-
tion.
This invention relates to certain improve-
r5 ments in motors adapted especiallyfor domes-
tic use, its object being to provide a cheap,
compact, durable, and efficient automatic mo-
tive mechanism which may be utilized for driv-
ing various household apparatus, such as
20 churns, cradles, fly-brushing machines, sew--
ing-machines, and other implements.
fMy invention consists in a novel combina-
tion and arrangement of devices, whereby the
motor is readily connected to different ma-
25 chines and a smooth and uniform movement
is secured.
The accompanying drawing represents a
perspective view of my improved motor.
The letters A A' indicate two upright plates,
30 in which are formed the bearings of the vari-
ous arbors of the train of gear-wheels, thelower
ends or feet of these plates being secured to
the bench B, and their upper ends connected
by a cross-bar, O. To the shaft d of the main
35 wheel D, between the lower ends of the plates
A A', is secured the inner end of a coiled mo-
tive spring or springs, the outer end of which
is secured to the inner periphery of a barrel,
D', which is firmly fixed to the inner side of
40 the plate A. The top shaft, E, of the train
carries at one of its projecting ends a crank-
wheel, F, and at its other end a balance-wheel,
G. The crank-wheel F has through it a slot,
h, extending from near its center to near its
45 periphery, and in this slot is arranged an ad-
justable wrist-pin, i, with which is connected
the pitman J, having its opposite end, in the
present instance, connected, by means of a
screw-pin, j, and thumb-nut j', with the recip-
50 rotating dasher-rodZK of a churn, the upperend of the said dasher-rod projecting through
a guide-bearing, 1, carried by an adjustable
arm, M', which is secured to the cross-bar C by
means of a screw, m, setting through a slot, m'.
By means of the adjustable arm M and screw- 55
pinj the reciprocating dasher-rod or any other
similar reciprocating device may be connected
with the motor at varying distances therofrom.
The balance-wheel G has arranged at one
side an extra weight, g, and the wheel is so 60
keyed upon its shaft as to bring this extra
weight on the opposite side of said shaft from
the connection of the pitman J with the crank-
wheel, in order to balance the shaft and give
the pitman and its connections a uniform mo- 65
tion. On the rearwardly-projecting portion of
the shaft d of the main wheel is arranged a
gear-wheel, N, which meshes with a pinion, O,
carried by a short shaft having at its end the
crank P. By means of this crank andthe gear- o
wheel and pinion the spring is wonld up.
Outside the gear-wheel N, on the main shaft,
is fixed a fusee, Q, to which is connected a
cord, R, passing upward and over a pulley, S,
which may be secured to a cross-beam, ceiling, 75
or other object, and has attached to its de-
peniding end a weight, T, which may be heavier
or lighter, as desired, to control the speed of
the machine. The object of this fusee, its cord,
and weight is to give a uniform speed to the 8o
motor-train, the cord being upon and unwind-
ing from the smaller portion of the fusee when
the springor springs are wound up completely,
and gradually unwinding from a larger diame-
ter of the frame, and exerting a greater force 8r
upon the shaft as.the spring or springs by un-
winding spend their force. Thus the increas-
ing power of the fusee compensates the de-
creasing power of the spring or springs.
The letter U indicates a brake-arm pivoted 90
to the plate A, and having its free end pro-
vided with pad u, of leather or similar mate-
rial, in position to be swung against the pe-
riphery of the balance-wheel.
By locating the motive spring or springs, its 95
inclosing-barrel, the winding apparatus, and
regulating-fusee at the lower end of the motive
train, I give the motor a firm base and steadi-
ness of action which it would not otherwise
have, and by mounting the motor upon the oo
