I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co, Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of my invention for IMPROVEMENTS IN AND RELATING TO MEANS FOR DRIVING
SEWING OR OTHER MACHINES" to be as follows:-
"
The object of this invention is to facilitate the work of an operator in driving a
sewing machine or the like.
According to the said invention I combine with the sewing machine to be driven,
a support for the operator, adapted to descend under the influence of the weight
of the operator and transmit motion to the sewing machine or the like.
The operator has no labour to perform except to move from the support occasion-
ally in order that the support may regain its initial position. I prefer to interpose
a train of wheels or analogous mechanism between the said support and the sewing
machine or the like to prevent the latter from running too rapidly.
Preferably I adapt the machine to run at a proper speed regardless of the weight
of the operator, by employing a governor which may be adjusted to offer greater
or less resistance to the motion of the machine.
The support may advantageously have combined with it a spring for returning
it to its initial position when it is relieved of the weight of the operator.
As it may be objectionable for the operator to remove from the support I combine
with the support a lever which may be rocked by the operator without getting off
the support to raise the support to the initial position.
To facilitate the starting and stopping of the machine I use a device actuated
by a treadle and adapted to impinge against the balance or fly wheel of the machine
in such manner as to either arrest the wheel or impart an impulse to it.

I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co, Patent Agents,
Southampton Buildings in the County of Middlesex do hereby declare the nature
of my invention for "IMPROVEMENTS IN AND RELATING TO MEANS FOR DRIVING
SEWING OR OTHER MACHINES and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:-
The object of this invention is to facilitate the work of an operator in driving a
sewing machine or the like.
According to the said invention I combine with the sewing machine or like
article to be driven a support for the operator adapted to descend under the
influence of the weight of the operator and transmit motion to the sewing machine
or, like article. The operator has no labour to perform except to move from the
support occasionally in order that the support may regain its initial position.
prefer to interpose a train of wheels or analogous mechanism between the said
support and the sewing machine or like article to prevent the sewing machine or
like article from running too rapidly.
Preferably I adapt the machine to run at a proper speed regardless of the weight
of the operator by employing a governor which may be adjusted to offer greater or
less resistance to the notion of the machine.
i.
The support may advantageously have combined with it a spring for returning
it to its initial position when it is relieved of the weight of the operator.
As it may be objectionable' for the operator to remove from the support I combine
with the 'support a' lever which may be rocked by the operator without getting off
the support to raise the support to the initial position.
To facilitate the starting and stopping of the machine I use a device actuated by
a treadle and adapted to impinge against the balance or fly wheel of the machine
in such manner as to either arrest the wheel or impart an impulse to it
In the accompanying drawing Figure 1 is a back view of a sewing machine and
operating mechanism embodying my improvements; Figure 2 is a' transverse
section of the stand and operating mechanism; Figure 3 is a trausverse section of
the stand showing appurtenances not illustrated' in Figure 2; and Figure 4 'is a
sectional view of a starting and stopping device. Similar letters of reference
designate corresponding parts in all the figures.

1.A designates a stand consisting of a' base piece a and table b which may be made
of wood, and side pieces c, preferably made of iron, erected on the base 'piece a and
supporting the table b. These side pieces may be connected to the base piece and
table by screws or other means.
OLL 10 745
B designatesia sewing machine secured by screws or other means to the table b.
This sewing machine.may be of any approved style.
C designates a train of wheels supported in a frame C¹ which is secured to one
of the side pieces c.
I will describe this train of wheels. A belt pulley or wheel s
is secured to a shafts. A ratchet wheel 8 is also secured to the shaft s'. The

page_text: shaft & has loosely mounted on it at one side of the ratchet wheel s² a gear wheel g³..
The gear wheel 83 has arranged upon its side which is the nearer to the ratchet:
wheel s¹ a spring actuated pawl that engages with the ratchet wheel 8³. The gear
wheels engages with a pinion 8 on another shaft. On the same shaft with the:
On the
pinion s is a gear wheel 85. The gear wheel 8 engages with a pinion 86.
same shaft with the pinion s is a gear wheel s'. The gear wheel s7 engages with a
gear-wheel 88 on another shaft. A gear wheel 8 arranged on the same shaft with
the gear wheel 88 engages with a gear wheel 810 on another shaft. A balance or fly
wheel 8 is arranged on the same shaft as the gear wheel 810. This balance or fly-
wheel 8 is formed so as to constitute a belt pulley. A belt 812 passes around it'
and also around a pulley 813 affixed to the driving shaft of the sewing machine B.
A strap D at one end is fastened to the pulley or wheel's and passes around the
same. Thence it passes around a guide pulley d thence around a guide pulley d
in a pillar E thence around a guide pulley d in the pillar E and its extreme end
extends to the shank of a stool like seat F to which it is securely fastened, by
screws or analogous means. The shank of the seat F works vertically in guides
coinprised in the pillar E.
A belical spring G coiled around the shaft 8' is fastened at one end to the belt
pulley or wheel s and at the other end to one of the side pieces c.
1
The operator of the sewing machine occupies the seat F. The weight thus
imposed on the seat causes it to descend. Its descent effects the pulling of the
strap D and thereby rotates the shaft s¹ against the resistance of the spring G.
Owing to the employment of the train of wheels C the descent of the seat for a
short distance effects the driving of the sewing machine B for a considerable time.
The descent of the seat to its lowest position will take a long time, say for instance
á half an hour.
After the seat reaches its lowest position the operator rises from it and then the
spring G rotates the shaft s and raises the seat to its highest position. When the
spring G thus actuates the shaft 81 the latter turns in the reverse direction to that
in which it turns when actuated by the seat and does not impart inotion to the
gear-wheel 8 and the gear wheels deriving motion from the gear wheel 83.
H designates a lever fulcruined in the pillar E and extending at one end under
the shank of the seat F and at the other end within convenient reach of the foot
of the operation. By pressing upon this lever and so transferring a portion of the
weight from the seat to the lever the seat may be raised to its initial or highest
position.
I designates a bell crank lever fulcrumed to one of the side-pieces c and having
one of its arms approximately upright and the other approximately horizontal.
The upright arm is bent so that it will not come in contact with the shaft s¹ when
the lever is vibrated. The horizontally extending arm has a spring J, connected to
it, for pulling it upwards. It is also connected by a link J' with a treadle J2. The
upright arm of this lever is provided with a tubular section e which is longitudinally
Blotted and secured to the lever by a screw so as to be susceptible of movement.
This section is furnished at the outer end with a block of india rubber or like
material f. Within the tubular section between the block of india rubber or
like material and the end of the lever a spring g is arranged. This spring impels
the movable section e upwards.
To start the sewing machine the operator presses down the treadle J2 and thereby
forces the upright arm of the lever I under and past the lower part of the balance
or fly wheel 8 in the direction indication by the arrow adjacent to the lever. The
lever in passing the balance or fly-wheel will rotate it. The yielding tubular
section e of the lever I is advantageous for it compensates for the curve of the
periphery of the wheel and allows the lever to travel longer in contact with it than
otherwise would be possible. The lever is kept in this position so long as the
sewing machine is to be used.
When it is desirable to stop the sewing machine the treadle J' is released where.
upon the lever I is forced against the balance or fly wheel by the spring J and

page_text: returned to the position which it occupies in Figure 3. The wheel is then brought
to a state of rest.
