Improvements in Button-sewing Machines or Attachments.
I REGINALD HADDAN of the firm of Herbert & Co. Patent Agents of 18 Buckingham
Street Strand W.C. in the County of Middlesex, Civil Engineer do hereby
declare the nature of this invention, a communication to me from abroad by
Felix Engel of 21 Graskeller, Hamburg in the Empire of Germany Engineer and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
This invention consists in an improved construction or combination of parts suitable
for use in a sewing machine adapted for sewing perforated buttons onto cloth or any
material the object of the improvements being to facilitate the introduction and adjust-
ment of the cloth or material under the cloth holder, to provide mechanism
requiring less power to work and to give a steady guiding to the button.
Reference being made to the annexed drawing showing the improved mechanism
as constructed on a sewing machine of the Wheeler and Wilson type.
Fig. 1 is a side elevation of the machine partly in section. Fig. 2 is a plan of the
machine plate with the head removed. Fig. 3 is a side elevation of the button
sewing device partly in section and Fig. 4 is a side elevation of the lower end
of the button sewing device showing the same at the moment when the material
with the button placed thereon is inserted underneath the mechanism raised for this
purpose.
A is the head of the machine, n is the needle, m the needle bar and h the upper
thread.
A metal frame a which on the lower surface has a groove or hole for receiving the
button e is revolvably journalled in the arms of a fork g by means of the screws s and s¹
said fork swinging on pin c. The frame a is pressed down by the spring d upon the
cloth holder B the object of which is to hold the material p to which the button e is
to be fastened and to shift the same after each stitch. This cloth holder or presser
foot B is secured to or made with the arm revolving on pin k and which is pressed
down upon the plate, that is to say upon the material p by the spiral spring o. The
cloth holder can be raised by a cord 9 connected with a pedal attached to draw down
the end of the lever l. When the cloth holder B is raised the frame a is raised like-
wise as the same rests upon said holder. The frame a has a hole in the centre which
permits a passage of the needle into the button located underneath the frame. After
each stitch the frame is shifted so that the needle penetrates alternately the one
or the other hole in the button and thus attaches the button to the material.
This displacement of the frame a is operated in the following manner.
The rod t is moved to and fro by the lever u pivoted on pin u, its other end engaging
in the slot in the disc i. This rod t is fastened at the other end to a frame which
y
serves as a bearing for the pin c which carries the fork g and also for the pink on
which the lever is located. The frame y is pivoted to the machine head by means
of the rod z. When during working of the machine the rod t is moved to and fro,
the frame y moves to and fro and causes thereby the oscillations of the button frame a
and cloth holder B which carries along the button and cloth and thus moves the latter
to and fro underneath the needle. The displacement is regulated according to the
distance of the button holes by the adjustment of the rod t in the slot to of the
lever v.
For the purpose of changing, the frame a is secured to the fork by means of screws;
according to the size and kind of the buttons to be sewn on a suitable frame is to be
inserted into the fork g.
The spiral spring o is suitably fastened at the upper end to an arm 3 which is secured
to the rod z so that the whole system revolves with the rod z as soon as the connecting
rod t commences to move.

page_text: When a new button is to be placed underneath the mechanism or if a sewn button
is to be removed the arm is pressed or drawn down so that the frame a is raised
with the presser B as shown by Fig. 4. After the material p with the new button to
be sewn on which has been previously placed upon the material at the place where it
should be attached is placed underneath the frame a, the lever is released so that the
frame a is placed over the button.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The combination with the cloth presser or holder B and the button holder a of
the pivoted frame y carrying said cloth holder and button holder and adapted to be
oscillated for the purpose set forth.
2. The combination of the rod z the frame y attached thereto, the cloth bolder B
pivoted in said frame y the fork y pivoted in said frame the removable button
holder a in said fork arranged for oscillation about said rod z substantially as and for
the purpose set forth.
