Improvements in and relating to Spring Motors.
I, ELI SAMUEL REED, a citizen of the United States of America, residing at
No. 101, Helen Street, in the City of Chattanooga, County of Hamilton and State
of Tennessee, one of the United States of America, Inventor, do hereby declare the
nature of this invention, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This invention relates essentially to an improvement in spring motors adapted
especially for the purpose of driving sewing machines, but also useful for actuating
other kinds of machinery. The object of the invention is to provide a simple, cheap,
light and efficient spring motor, which will consist of as few parts as possible, may be
easily wound up with the expenditure of a trifling amount of power, may be readily
and speedily applied to any kind of a sewing or other machine, may be quickly
stopped or started, and which will conform to the highest possible degree to the
multitude of requirements exacted of a motor of this kind. A principal object of
the invention is to diminish the friction to the lowest minimum. The invention
therefore consists essentially in the construction, arrangement and combination of
parts, and in certain modifications thereof, substantially as will be hereinafter
described and claimed.

In the group of Figures 1-15, like letters denote like parts. In the group of
Figures 16-20, like letters denote like parts, and in the group of Figures 21-25,
like letters denote like parts.
Referring first to Figures 1-15, I will proceed to describe the leading form of
my improved spring motor. In these figures, A, denotes the horizontal table of a
sewing or other machine with which it may be desired to use the motor.
This may
be any kind of a table belonging to any kind of a machine. My purpose is to
locate my motor directly beneath the table, securing it thereto, so that it may be out
of the way and may occupy as small a space as possible.
The frame of my improved spring motor is secured to the underside of the
machine table, A, and consists preferably of the following parts arranged in the
following manner, so that the several mechanical parts constituting the motor may
be conveniently arranged in connection therewith, and so that all the needed
adjustments for perfecting the operation of the motor may be easily and readily
accomplished.
At the left hand end of this frame are the parallel vertical bars, B, B, see
Figure 1, placed a suitable distance apart and provided at their upper ends with
slotted flanges, see Figure 2, through which pass securing screws or other devices
by means of which said upright bars are firmly connected to the under surface of the
machine table. The slots in the said flanges permit a slight lateral adjustment of
these uprights, which can be easily accomplished at any time by loosening the
attaching screws, adjusting the bars, and then tightening the screws again. Con-
nected to the lower ends of these uprights, or made integral therewith, is a trans-
verse horizontal bottom bar, B', see Figure 2, and Figure 3. C, C, denote another
pair of parallel uprights similar to the uprights, B, B, at a suitable distance from
said uprights, B, B, near the middle of the motor frame, and similarly connected at
their upper ends by means of screws or other suitable attaching devices as shown,
to the under surface of the machine table, A. The lower ends of the uprights, C, C,
are connected together by means of the transverse horizontal bottom bar, C', which
bar is made integral with the longitudinal horizontal bottom bar or plate, C³. The
end of the longitudinal part, C³, nearest to the transverse bar, B', is designated c,
and is formed suitably to permit it to pass between parallel lugs or flanges formed
on the underside of said bar, B'. The end, c, is also provided with a couple of slots
through which pass screws that enter the underside of bar, B¹, see Figures 2 and 4.
Thus the end, c, is adjustable endwise beneath the bar, B¹, and in consequence the
longitudinal part, C³, and its integral transverse part, C, are adjustable. The
end, c, is further provided with a nut or internally screw-threaded box made
integral with the underside thereof and receiving one end of a set screw, g, the
other end of which passes through a perforation in the flange on the edge of the
bar, B. By adjusting this set screw it will be obvious that the parts, C³, and C*,
may be adjusted so as to have their position relative to the bar, B¹, and uprights, B, B,
as well as to the other adjacent parts sufficiently changed to enable all the

page_text: mechanical devices to operate in perfect union for the accomplishment of the best
possible results in the practical use of the motor. At the left hand end of the
frame is a skeleton upright D, which is parallel to the uprights, B, and C, and
which is secured at its upper end to the under surface of the machine table. The
lower end of said skeleton upright, D, is provided with a bevel tongue which is
adapted to dovetail between the bevel flanges, c², c², formed on the upper side of
the longitudinal bar, C, at the end thereof opposite the end c. The lower dove-
tailed tongue is connected to the bar, C³, by means of a suitable connecting screw,
see Figure 3.
Furthermore, the motor frame comprises a lower or bottom skeleton frame, E,
shown in sections in Figures 3 and 8, and in plan in Figure 2, said frame, E,
having one part parallel beneath the longitudinal bar, C³, and another right-angled
integral part parallel beneath one side of the transverse part, C, as shown in the
plan in Figure 2. Said skeleton bottom frame, E, is securely connected to the
lugs, c', e, on the underside of the bar, C³, and a lug on the underside of the bar, C",
by suitable attaching screws, and the main purpose of this skeleton part is to
permit the arrangement therein and therewith of the devices by means of which
the spring is wound.
Thus it will be seen that the frame taken altogether is a skeleton construction,
consisting of the fewest possible parts, and therefore being as light as is consistent
with sufficient strength to support the mechanical devices. The other parts of the
motor frame are the horizontal transverse bars, B2, C1, and C. The transverse
horizontal bar. B² connects the uprights, B. B, and is located a short distance
below the upper ends of these uprights. The transverse bars, C', and C2 connect
the uprights C, C. These several transverse pieces may be connected in any
manner that may seem best. A convenient way of locating the cross bar, C2, in
place, is to form lugs on the inner sides of the uprights, C, C, and allow the cross
bar, C, to rest at its ends thereon, said ends being likewise enlarged to permit
attaching screws, which pass through the uprights, C, C, to enter them and firmly
secure the cross bar in place.
F, denotes a drum of suitable width and diameter having a cover, F1, which is
preferably a skeleton cover, and which is secured to the upper edge of the drum, as
shown. The underside of the drum is formed with a central boss or enlargement
which is seated upon the bottom bar, C³. Said under part of the drum is preferably
made in skeleton form, as shown in Figure 2, consisting simply of the radial
arms, a, a, which arms are preferably provided on their upper sides within the
drum, with ribs, as indicated in Figure 3, upon which rests the spring, G, the
ribs serving to diminish the friction when the spring is being wound or is
unwinding.
Passing centrally through the drum, F, and likewise through the bottom bar, C³,
of the motor frame, is a tube or shaft, H, which may be either hollow or solid,
and which is formed integral with a friction wheel, H', on the lower end of the
part H, beneath the bar, C³, as shown in Figure 3; the said friction wheel and its
integral shaft or tube being shown in detail in Figure 6. The upper end of the
tube, H, has a bearing in a circular recess formed in the underside of the transverse
bar, C². (See Figure 3.) Surrounding the tube, H, within the drum, F, is a
sleeve or thimble, G¹, which is keyed to the said tube H, so as to rotate therewith.
The key, g, shown in Figure 6, is used to effect the connection. Furthermore, it
will be seen that the spring, G, is located within the drum, F, and is coiled around
the sleeve, G¹, one end of the spring being connected to the wall of the drum, as
shown, while the other end is connected to the sleeve, G¹, by means of a screw or
other attaching device, g'. This spring, G, drives the mechanism of my machine.
It may be of greater or less size and power. Obviously the rotation of the friction
wheel, H', and its integral tube, H, in one direction will revolve the connected
sleeve, G', and thus cause the connected sleeve, G', to wind up and become closely
coiled, so that when it unwinds it will serve to actuate the gearing, the drum, F,
during the unwinding of the spring revolving upon the tube, H, which serves as a

page_text: journal therefor. Instead of the friction wheel, H' I may employ a ratchet wheel, H',
see Figure 13, which is an equivalent construction.
The drum, F, is provided with a friction gear or friction wheel, I. This may be
of equal or less diameter than the drum. In the example shown in the drawings,
the friction wheel, I, is of less diameter than the drum, and is located above the
latter, being mounted upon the skeleton cover of the drum and securely connected
thereto. This friction wheel, I, may be differently arranged with relation to the
drum to which it is connected. Experience will dictate how it may be best affixed
thereto, and I reserve the liberty of adopting the best form thereof which may be
suggested in practice. This friction wheel, 1, is preferably provided with a grooved
perimeter or periphery.
The drum or barrel, F, connects with the driven machine through a novel system
of gearing, which I will now proceed to describe.
This
Parallel to the tube, H, is a vertical shaft, J, having a bearing at its upper and
lower ends in the cross bar, B, and the bottom bar, B₁, respectively. The upper
and lower ends, j,j, of this shaft are preferably pointed so that the friction thereof
within the bearings may be diminished. The bearing in the bar, B', is simply a
seat formed therein having an annular recess around the shaft, J, adapted to receive
the oil or other lubricant and keep the action thereof constant upon the bearing.
The bearing of the upper end of the shaft is a screw-threaded plug, ', which
screws into an internally screw-threaded opening in the cross-bar, B².
plug, b, may therefore be adjusted up or down so as to regulate the position
thereof and take up for wear. It is provided with the central vertical passage, at
the upper end of which is formed a cup, said passage being adapted to convey the
oil or other lubricant to the upper shaft bearing, j, while the cup receives the
lubricant and delivers it to the passage. This is shown in Figure 3. The shaft, J,
at about midway thereof is preferably formed with an enlargement or collar, J.
Beneath this is a screw-threaded section, J. On this screw-threaded section is a
friction wheel, b, being a thin horizontal wheel made of some suitable material.
This wheel, b, may be adjusted up or down upon the screw-threaded portion.
Beneath it is a nut, j, so that after the wheel has been adjusted up closely against
the collar, J', the nut, j, may be screwed firmly into place against the underside of
the wheel, and the wheel thus securely and rigidly connected to the shaft at the
proper point. The periphery of this friction wheel, b, is in close contact with the
periphery of the friction wheel, I, belonging to the drum, F, and it enters
the groove in the periphery of the wheel, I, thus increasing the tractive force.
Likewise on the vertical shaft above collar, J2, is a friction wheel, K, preferably
having a considerably larger diameter than the friction pinion, b, the hub of said
friction wheel, K, having a set-screw whereby it is firmly connected to the shaft, J,
and the periphery of said wheel, K, being grooved. Parallel to the shaft, J, and
directly in line above the tube, H, is another short vertical shaft, L, having
bearings at its upper and lower ends in the transverse bar, C', and the transverse
bar, C, respectively, said upper and lower ends of the shaft, L, being pointed
at, 1, 1. The bearing for the lower end, 1, of the shaft, L, is simply a proper
recess in the cross bar, C, permitting space enough to contain a lubricant around
the shaft, which may act at all times upon this bearing so as to keep the action free
and easy. The bearing for the upper end of the shaft, L, is formed in a plug, l,
similar to the plug, b, said plug,, being screw-threaded and situated within a
screw-threaded opening in the transverse bar, C¹. On this shaft, L, is a friction
pinion, d, and also a bevel friction wheel, M, having a hub, M', provided with a set
screw, e, whereby it is rigidly connected to the shaft, L. The friction wheel, M,
has a flat rim and is beveled horizontally so that it serves as a beveled friction
wheel, being of a diameter substantially equal to the friction wheel, K.
friction pinion, d, engages with the grooved peripheral surface of the wheel, K.
The shaft, L, is screw-threaded for a certain portion of its length at and below
where the friction gear, d, is located, and a nut, I, travels on this screw-threaded
part and binds the friction pinion, d, closely between it and the hub, M', of the
The

page_text: beveled friction wheel. In the right hand skeleton part, D, of the motor frame is
journaled a horizontal shaft, f, having suitable bearings in said frame. That
portion of this shaft outside of the frame, D, is preferably screw-threaded, and on
this screw-threaded portion is a bevel friction pinion, N, on one side of which is a
nut, n, and on the other side, a nut, n', the said bevel friction pinion being
adjustable within certain limits. This friction pinion is in contact with the bevel
friction wheel, M, see Figure 3.
Likewise on the shaft,, within the skeleton frame, D, is a peripherally grooved
pulley, k, around which passes a belt or band, m', which runs over the wheel, m, on
the sewing machine shaft, all as clearly shown in Figure 1. Thus it will be seen
that the belt, m', serves to carry power from the peripherally grooved pulley, k, to
the shaft of the driven machine, whatsoever that machine may be.
Referring to Figure 3 it will be seen that the bevel friction pinion, N, is
beneath the bevel friction wheel, M. This drives the pulley, k, in one direction,
as shown by the arrow alongside of said pulley, and thus rotates the shaft of the
driven machine in one certain direction, imparting thereby to the driven machine
a corresponding actuation and work. The beveled friction wheel, M, however, is
reversible, so that it may be applied to the pinion, N, either above or below,
thus rotating the latter either in one direction or the other, as may be desired.
In Figure 12 the wheel, M, is shown as applied to the pinion, N, below the
latter. This reversal of parts is easily accomplished by simply removing the plug
bearing, , and then reversing the shaft, L, which carries with it the connected
wheels, M, and d, placing them in the position shown in Figure 12, where the
pinion, d, engages the periphery of the grooved friction wheel, K, just as it does
in Figure 3, and the beveled friction wheel, M, has its beveled friction surface
beneath the beveled pinion, N, acting upon the latter just as it does in Figure 3
only in a reverse direction, and causing a reverse motion of the pinion, N, and con-
sequently a reverse rotation of the pulley, K, which now revolves in the direction
shown by the arrow in Figure 12, and consequently imparts to the driven machine
a change in its direction of movement.
Below the frictional wheel, H¹, is a bevel gear or pinion, O, having on its upper
side or face, see Figure 5, a flange or lug, o, and a short rounded stem, the stem
and flange being integral with each other and with the gear, and on its lower side a
short pointed shaft or projection, o'. The flange, o, and integral stem are adapted
to enter a recess, h, formed in the face of the friction wheel, H', while the 'stem
referred to projects a short distance into the tube, H, as shown in Figure 3. In
this way the gear, O, is loosely connected to the friction wheel so that it will
rotate therewith, but can be easily disconnected therefrom when desired. It will
be noted that it supports the said wheel, H, and its tube, keeping the upper end of
the latter within its bearing in the cross-bar, C. The downward shaft or pointed
projection, o, has a suitable bearing formed in the part of the skeleton frame,
E, directly beneath the gear, O. Thus the gear is free to turn, and in its turnings
it rotates the friction wheel, H'. By referring to Figures 3 and 4 it will be seen
that on opposite sides of the wheel, H', are dogs, P, P, seated loosely in sockets
formed in a longitudinal bar, C³, of the motor frame, said dogs having curved faces
which come in contact with the periphery of the wheel, H, and said dogs being
provided each with a spring, p, the tendency of which is to press the dogs against
the wheel. Figure 13 is similar to Figure 4, but shows a modification of certain of
these parts. In Figure 13 we find the ratchet, H2, substituted for the friction
wheel, H. We find the pawls, P, arranged in sockets, P1, but acting on these pawls
are springs, p', which take the place of the springs, p, said springs, p¹, consisting of a
coil or two with one end against a lug and the other end against the pawl, as shown.
Here, then, is a sort of clutch device. As the wheel, H', or H2, revolves in one
direction it will push the dogs, P, out of its way, thereby compressing the
springs, p, or p', as the case may be, but these dogs, P, quickly clutch the said
wheel, H, or ratchet, H2, and prevent any reverse movement thereof. Thus the
wheel, H', or H, and the connected tube, H, may be rotated forward a sufficient

page_text: number of times to wind the spring, G, tightly and coil it closely together, and the
dogs, P, will serve to hold the collar, H', and consequently the spring in the
position in which the latter may thus be placed. The diameter of the tube or
shaft, H, relatively to the friction wheel, H', may vary. I am not therefore
restricted to the particular size of this part as shown in the drawings, but reserve
the liberty of making the collar or wheel of any size and diameter relatively to the
tube or shaft with which it is formed integral.
In order to rotate the gear, O, and thus wind the spring, G, I provide certain
winding devices consisting of the following parts:
R, denotes a horizontal shaft journaled in suitable bearings in the skeleton
frame, E, the inner end of said shaft, R, being preferably pointed and having its
bearing as shown in Figure 8, closely adjacent to the bearing of the downwardly
projecting pointed shaft, o, which belongs to the gear, O, so that an oil hole, as
shown in Figure 8, may communicate from one bearing to the other, and thus the
lubricant which is fed in around the bearing for the shaft, O¹, will leak through
into the other bearing and oil the latter sufficiently to permit easy movement of
the shaft, R. Secured upon this shaft, R, is a beveled pinion, RI, which inter-
meshes with the pinion, O, said pinion, R', being vertically placed. Likewise on
the shaft, R, are two collars, r, r, provided with set screws so that they may be
adjustable upon the shaft, one of said collars being screwed up tightly against the
pinion, R¹, while the other is screwed tight up against the outer bearing of the
shaft, R.
Q, denotes a winding lever having at the outer end thereof a suitably formed
handle attached at right angles as usual, and easy to be grasped for the purpose of
vibrating said lever. The end of this lever is formed with a circular opening, see
Figure 11, wherein is placed a friction wheel, Q, which has a central square
opening of suitable size to fit nearly over the square end of the shaft, R. The
wheel or disk, Q', is held within the recess which it occupies in the end of the
lever, Q, (covering as it does, the circular opening in said end) by means of the
plate, Q, which is perforated with an opening less in diameter than the diameter of
the disk, Q, said plate, Q3, being fastened to the face of the lever, Q, by screws or
other means, it being shown in detail plan in Figure 10. Within the end of the
lever adjacent to the periphery of the disk, Q', is a dog, Q, having a curved end
in contact with the periphery of the disk, Q, said mechanism thus operating and
acting as a clutch, for while the lever vibrates in one direction, the dog, Q³, will
slip loosely over the periphery of the disk, the latter remaining stationary, but
when the lever, Q, vibrates in the opposite direction, as shown by the arrow in
Figure 11, the dog will clutch the disk, thereby causing the same to rotate, and in
consequence causing the rotation of the shaft, R, the gearing at the end thereof,
the friction wheel and its integral tube on which the drum revolves, and thereby
effecting a partial winding of the spring. A few vibrations of the winding lever, Q,
will therefore wind the spring up to its highest tension. It will be observed that
the winding lever, Q, may vibrate in either direction, and that if it is placed upon
the shaft, R, in the position shown in Figure 1, the result of vibrating it in the
direction shown by the arrow in this figure, will be to wind up the spring, whereas
if it be placed upon the shaft R, in the position shown in Figure 8, it may be
vibrated in the reverse direction with the effect of winding the spring. Further-
more it will be observed that it can be easily detached from or attached to the
shaft, R. After the spring has been wound, the handle being in the position shown
in Figure 1, it can easily be removed and the lever placed upon the shaft as it is
shown in Figure 8, whereby it is out of the way, and the right-angled handle at the
end thereof projects inwardly instead of outwardly, the parts are more compactly
arranged and less in the way of the operator in running the machine.
In order that the motor may be started at any moment with promptitude, or may
have its motion quickly and speedily arrested at any time and in fact governed and
controlled at all times with little effort on the part of the operator, becomes
necessary to provide an efficient brake device. I will therefore at this point

page_text: explain the form of the brake herein employed, although other forms may of
course be used with other forms of the motor. I preferably apply this brake to the
pulley, k, which we have seen carries the band or belt, m', which communicates
motive power to the driven machine.
Figure 9 illustrates clearly a certain part of the brake mechanism, and Figure 1
shows the balance thereof, while Figure 2 indicates in bottom plan the arrangement
of certain of the parts. S, designates a horizontal lever which is fulcrumed below
the machine table, at . Said lever, S, carries the brake shoe, S', which enters
the grooved periphery of the pulley, k. The shoe end of the brake lever is
provided furthermore with a projection, x, which carries a spring, ', which bears
against the frame and presses downward upon the brake shoe holding the latter
tightly against the grooved periphery of wheel, k. Near the other end of the
brake lever, S, and at right angles thereto is a right-angled or bell crank lever, T,
fulcrumed at its vertex on the pin, t, one arm of which lever bears upon the end of
the lever, S, preferably entering a slot or notch, 83, cut in said lever near the end
thereof. To the end of the other arm of lever, T, is connected a rod or cord, v¹,
shown clearly in Figure 1, which preferably runs to the other side of the motor and
is attached to one end of the lever, V, fulcrumed at, v, on some suitable part of the
motor or machine frame. Vertically below this lever, V, is another lever, U,
which carries a foot or knee pad, u', said lever, U, being fulcrumed at u, and having
its upper end pressing loosely against the lower end of the lever, V, below the
fulcral point of the latter. It will be obvious that by pressing upon the pad or
plate, u, and pushing it in the direction shown by the arrow in Figure 1, the
result will be to shift the lever, U, which will interact with the lever, V, shifting
it and moving its upper end in the direction shown by the arrow, and thus pulling
the cord or rod, ', sufficiently to shift the bell crank lever, T, and thus depress the
outer end of the lever, S, whereby the brake shoe, S', will be removed from the
pulley, and the spring, s, temporarily contracted. When the pressure upon the
lever, U, is released, the tension of the spring, ', will serve to restore the brake
shoe to its position in contact with the periphery of the wheel, k. Figure 15, is
similar to Figure 9, but shows a modification in the brake mechanism, a large
portion thereof being dispensed with. In Figure 15 a rod passes from the treadle
and is connected directly with the end of the lever, S. This is shown also in
Figure 14. This is simpler than the arrangement in Figure 9 and better for
certain places.
The operation of my improved spring motor will be evident from the foregoing
description of the construction and arrangement of the several parts. A few
vibrations of the winding lever will be sufficient to quickly and surely coil the
spring to its highest tension. This winding operation may take place at any time
whether the motor is running or at rest. When it is desired to start the machine,
the operator will simply press upon the brake mechanism so as to remove the brake
shoe from the pulley, k, and allow the coiled spring to actuate the train of
multiplying friction
gears so as to drive the shaft, f, with the pulley, k, thereon,
and thus actuate the driven machine. If it be desired to drive the machine in a
reverse direction all that the operator needs to do is to reverse the position of the
friction wheel, M. The several adjustments in the different parts of the frame and
for the different wheels of the motor mechanism enable the operator to keep his
machine in perfect condition at all times, so that it will do the best possible work
and cannot get out of order.
Furthermore, the provision of a train of friction gearing constitutes one great
excellence and merit in this invention. Not only is the structure cheap to build, but it
operates with very great efficiency, a higher speed is attained, there is no noise in
the operation of the parts, and the engagement of the friction gears forms a very
easy and light running movement. Certain of these friction wheels may be made
of rubber if desired. It will also be obvious that instead of friction gears, cog
gears may be substituted, as cog and friction gearing are well known equivalents
for each other. Figure 14 is similar to Figure 3, and indicates the substitution

page_text: of cog gears for the friction gearing shown in Figure 3. Instead of the friction
wheel, M, I employ in Figure 14 a bevel gear wheel, W, which engages a gear
wheel, X, used in lieu of the friction pinion, N. On the shaft of gear, W, is a
cog pinion, W!, used instead of the friction pinion, d, said cog pinion, WI,
engaging a gear, W2, used in lieu of the friction gear, K, of Figure 3, while the
spring case of Figure 14 is provided with a gear wheel, Y, in place of the
friction pulley, I, of Figure 3, and so we might go on enumerating other instances
of the substitution of a cog gear for a friction gear.
Referring now to Figures 16, 17, 18, 19, and 20, I will explain the modified
form of my improved motor, which is illustrated in those figures. A, denotes the
sewing or other machine table, to the underside of which the motor frame is
secured This frame is preferably of a skeleton form, having the horizontal bottom
bar, B, together with the transverse bottom bars, B, and the upright side bars, B¹,
whose upper ends are secured by means of screws or otherwise to the under surface
of the table, A. This frame is enclosed, if desired, within an external casing, «,
of thin sheet iron or other metal.
F, indicates the drum which contains the drive spring, said drum having a
cover, F, fitting neatly into a rebate around the upper edge of the drum, the
underside of the drum being formed with a central boss or enlargement, 1, which is
seated upon a corresponding boss or enlargement, m, on the bottom bar, B. Passing
centrally through the drum and likewise through the bar, B, is a tube or sleeve, NT,
formed integral with a ratchet wheel, N, located below the bar, B, said ratchet
having also integral therewith the downwardly extending tube section, N2, which
has a bearing in a circular recess in the rectangular strap, M, which is securely
fastened to the underside of the bar, B. Within the ratchet tube or sleeve, is the
vertical shaft, E, having bearings at its upper and lower ends in the cross piece, C¹,
and the strap, M, respectively. The drum, F, has formed on the outer surface
thereof a series of gear teeth making a gear wheel, H, integral with the drum, the
teeth being of suitable size. Within the drum and coiled around the ratchet tube
is a spring, G. One end of this spring is connected to the wall of the drum and
the other end to the ratchet tube, N', said spring being of greater or less size and
power. The drum or barrel, F, connects with the shaft, E, through a novel system
of gearing, which I will now proceed to describe.
Parallel to shaft, E, is a vertical shaft, D, having a bearing at its upper and
lower ends in the cross bar, C, and bottom bar, B, respectively. A pinion, I, is
keyed or otherwise rigidly secured on this shaft, which pinion engages the drum
gear, H.
A large gear wheel, J, is also keyed on shaft, D, above the pinion.
This gear, J, will preferably be considerably larger than the pinion, say six times
as large, for example, since the function of this gearing is not only to transmit
motion to shaft, E, but also to multiply and greatly increase the number of its
revolutions. The gear wheel, J, engages a pinion, K, keyed to shaft, E, above
drum, F, said pinion, K, being considerably smaller than gear, J, say one-sixth as
large, i.e., about the size of pinion, I. Between the pinion, K, and the drum
cover F¹, is a cross bar, C³, similar to cross bars, C, and C¹, and fastened at each
end to one of the side uprights, B'. The drum cover, F, preferably has a central
boss, F, which rests beneath cross bar, C, and the ratchet tube, N¹, finds a
bearing at its upper end in said bar, C. On the shaft, E, above the pinion, K,
and keyed firmly to said shaft, or if desired, integral with pinion, K, is the main
driving wheel, L, having a grooved periphery which receives the drive belt or
cord, h. The cord, h, runs horizontally from the drive wheel, L, and then passes
around vertical pulleys, R, R, carried by brackets, R, R', which give to the belt a
vertical direction and permit it to be easily applied to the band wheel of the sewing
or other machine with which the motor may be used, see Figures 16 and 17.
All the various skeleton constructions depicted in the drawings are intended
to permit lightness in the machine, together with ease of operation, it being
essential that a spring motor should be of light weight, adapted to be easily
applied to any kind of a machine, and capable of being wound with the least

page_text: possible expenditure of physical power. Further, the bearing ends of the
shafts, D, and E, are pointed at d, d, and e, e, respectively, and these pointed ends
enter correspondingly shaped bearings. This arrangement enables the shaft to
operate easily with little friction. Suitable perforations or openings are also
provided at each of these bearings to permit easy lubrication. Further, it is found
of advantage to arrange a plate, r, alongside of a part of the periphery of
wheel, L, and beneath said periphery, said plate having a right-angled flange
which is secured to the cross bar, C, and serving to keep the belt from dropping
off the wheel when loosened, see Figures 17 and 18.
I will now explain the brake used with this modification: P, denotes a flat
spring secured at its bottom end to the bar, B, of the main frame. It is arranged
vertically and carries at its upper end a shoe, p, adapted to press upon the
periphery of the drive wheel, L, and preferably shaped to enter the belt groove
in this wheel. The spring, P, is tensioned so as to hold its shoe with a strong
constant pressure upon the wheel, the pressure being sufficient to keep the wheel
from rotating during and after the spring has been wound up to its highest tension.
Evidently, as soon as the brake is removed from the wheel it will be free to turn.
The spring, P, is provided at its upper end with a horizontal arm p, which is
perforated near its outer end. Through this perforation passes the upper end of
a brake rod, Q, which is connected to arm, p', one form of connection comprising
a terminal ball, q, above the arm, and a pin, y', below the arm, the ball and pin
being on rod, Q. The lower end of the brake rod may be connected as shown
in Figure 16 to a treadle, S, which has a pin entering the socket on the brake
rod, for instance. By pressing the treadle with the foot the pressure of the brake
shoe may be relaxed and the motor and machine set in operation. By removing
the foot from the treadle the brake may be re-set, the drive-wheel gripped, and the
machine stopped. Thus by a simple movement of the foot the machine may be
started, stopped, and controlled at all times.
O, designates the winding lever here employed. It is located horizontally
beneath the motor, its inner end passing through the strap or guard, M, and being
perforated to permit the passage through it of the ratchet tube, N', above
described. The forward part of this lever is suitably bent at 0¹, so as to bring
the outer end into convenient proximity to the operator. The outer end of the
lever is provided with a drop handle, O2, pivoted thereto at, o, which handle
may be lifted into a horizontal position for operation and then allowed to fall
into a depending position out of the way, see Figure 16. Lever, O, carries
two oppositely located spring-actuated pawls which engage the ratchet wheel.
g, g, denote the lever pawls, and s, s, their springs which tend to press them into
engagement with the teeth of the ratchet, see Figure 19. On the bottom of the
bar, B, is another pair of oppositely located spring-actuated pawls, g¹, g, and
their springs, s¹, s'. Thus we have a series of four pawls, two on the lever and two
on the frame, and all acting on the ratchet. As the lever moves in one direction,
say to the right, see Figure 19, the lever pawls slip idly over the ratchet teeth,
engaging them successively, but producing no action thereon. When the lever
moves in the reverse direction, the lever pawls being in engagement, the ratchet
will be partially rotated, and while this rotation is taking place, the pawls on the
frame will drop into the teeth successively and thus hold the ratchet in whatever
position the lever, O, may place it. The result of rotating the ratchet will obviously
be to wind up the spring, G. One of the pawls, g, is preferably shorter than the
other, and likewise one of the pawls, g', is shorter than its companion. This is so
that a less movement of the lever, O, may result in causing the shorter pawl to
engage the ratchet, and a longer movement may cause the longer pawl to engage,
thus lessening the extent of movement of lever, O, necessary at times to accomplish
a result, and similarly with the holding pawls, a less rotation of the ratchet will
cause the short pawl to engage with the next tooth, and therefore slight movements
of the ratchet may be caught and not lost through non-action of the pawls. A few
B

page_text: vibrations of the winding lever will be sufficient to coil the spring as it operates
easily and quickly.
Referring now to Figures 21, 22, 23, 24, and 25, I will explain the still further
modification of my improved spring motor, illustrated in said figures.
A, designates the table of the sewing or other machine. One well known form
of sewing machine comprises a hollow head, I, which supports a shaft, J on which
is a band pulley, J'. Within the head, I, the shaft is provided with a bevel pinion, j,
that engages a bevel pinion, k, on the upper end of the vertical shaft, K, which
extends downward through the bottom of the head, and the table, its lower end
being beneath the latter and provided with a gear, L, which may be a cog or a
friction wheel. My motor is so constructed that I am easily enabled to connect
it with the lower end of shaft, K. The frame of my motor is preferably of a
skeleton form, consisting of bars, B', B, B2. The drum, F, has on its outer
surface gear teeth, making a gear wheel, H, and within it is the winding spring, G,
which drives the motor and has one of its ends secured to the wall of the drum.
The drum revolves loosely upon a solid or tubular shaft, P, which has a bearing at
its lower end in the strap or guard, M, fastened to the under side of the bottom
bar, B, said shaft, P, passing through an opening in said bar, and said shaft having
a bearing at its upper end in the horizontal cross piece, C', fastened between two
opposite side bars, B³, B. On the shaft, P, within the strap, M, is the winding
ratchet, N. Parallel to shaft, P, is the shaft, D, having a bearing at its lower end
in the bottom bar, B, and at its upper end in the transverse piece, C, of the frame.
On this shaft is the pinion, M', which meshes with the gear H, said pinion being
small. Also keyed to shaft, D, is the large gear, Q, which engages a pinion, R, on
a short drive shaft, E, which has a bearing at its lower end in the cross piece, C¹,
at a short distance from the end of shaft, P, and a bearing at its upper end in the
projecting piece, C³, see Figures 21 and 23. The shaft, E, carries also the gear
wheel S which meshes with the pinion, L, on the lower end of the vertical shaft of
the sewing machine. The gear, S, may be a cog or friction gear, and has a hub, S',
to which the brake is applied. O, denotes the winding lever, located horizontally
beneath the motor, its inner end passing through the strap or guard, M, and being
perforated to permit the passage of the shaft, P. Lever, O, has a drop handle, O',
and a pair of pawls, there being also a pair of pawls on the bottom bar, B, of the
frame, the construction and operation of this winding lever, pawls, and adjacent
parts, being similar to what I have already described in connection with Figure 19.
It will therefore be evident that the construction shown in Figure 24 is similar to
that in Figure 19, although the arrangement of certain other parts of the modifica-
tion varies. I will now explain the brake device employed with this modification.
I provide the lever, U, pivoted to a convenient part of the frame, so as to be in a
convenient position to be acted upon by the knee of the operator, and thereby
shifted in the position shown by the direction of the arrow in Figure 21. T, desig-
nates a horizontal rod which is held in suitable bearings, as for instance, the
projection, a, on the frame and the part a', see Figures 22 and 25. Hence this rod
will have an endwise movement. It carries at one end a brake shoe or pressure
plate, adapted to be brought into contact with the hub, S. Coiled around the
rod T, is a spring, b, which is tensioned between a pin in the rod and a projection, a.
The outer end of the rod, T, is perforated to permit the passage therethrough of
one of the legs, e, of a pivoted lever, d, said lever, being pivoted to the motor
frame, as shown in Figure 21, and having its legs, e, e, hooked at each end, one end,
as already stated, engaging the perforation in the outer end of the rod T, while the
other hooked end engages a perforation in one end of the knee lever, U. It will thus be
seen that the pressure of the shoe or pressure plate c, upon the hub, S¹, will hold
the mechanism of the motor at rest, acting thus as a brake and being sufficiently
strong in its pressure to keep the parts at rest even though the spring has been
wound to its highest tension. When the rod, T, is adjusted endwise so as to
remove the pressure plate, c, from the shaft, E, the parts of the motor will be

page_text: free to run under the impulse of the actuating spring. Evidently when the knee
lever, U, is pressed by the knee so as to shift it in the direction shown by
the arrow in Figure 21, the lever, d, will likewise be shifted, thus moving the
rod, T, endwise and releasing the brake from the hub, S', so as to set the motor
mechanism free. A simple pressure of the knee is all that is required to stop
or start the mechanism or graduate the speed. Attention is here called to the
fact that the gear on the lower end of the vertical shaft, K, of the sewing
machine may be a cog gear, as the gear, L, in Figure 23, meshing with a cog
gear wheel, S, on the shaft, E, or it may be a friction gear, as, L', shown in
Figure 25, which gear, L', is in frictional contact with the periphery of the
frictional wheel, S, on the shaft, E. In this variation of the invention as
illustrated in Figure 25, the brake mechanism to be employed is the same as
shown in Figures 21 and 22, with the trifling difference that the brake shoe or
pressure plate, c, instead of being applied to a hub on the shaft, E, is applied
directly to the periphery of the friction wheel, S³.
Many changes may doubtless be made in the precise structure and relative
arrangement of the several parts of the motor herein described, and the parts of the
several modifications thereof, without departing from my invention, and I therefore
reserve the liberty of varying the construction and adopting such changes as
experience may from time to time dictate.

tion, and in what manner the same is to be performed, I declare that what I
