Improvements in Button-holders for Button-sewing Machines.
I HERBERT JOHN HADDAN of the firm of Herbert & Co. Patent Agents of
18 Buckingham Street, Strand W.C. London 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 relates to those sewing machines for the sewing on of buttons in
which, heretofore the button has been placed in a metal case or oncasing plato suitable
to its size which is moved to and fro in such a manner by the machine by turning
and shifting that the needle of the machine penetrates alternately through the different
button holes of the button or in case of cloth buttons through the button at different
places and thus causes the fastening of the button to the material located
underneath.
As the metal case has to guide the button in an exact manner it is necessary
that the button should fit exactly into the case, it has been necessary therefore to
provide the machine with cases suitable in size for each size of button.
The object of this invention is to shape the case thus for the reception of the button
that without removing it from the machine it may be adjusted to suit all usual sizes
of buttons whereby the troublesome exchange of the case is obviated.
The invention is represented in the accompanying drawings of which
Fig. 1 is a front elevation,
Fig. 2 a side view and
Fig. 3 a plan of the part in question of the sewing machine which is provided with
adjustable button holder.
Figs. 4 to 8 are detail views of the button holder itself removed from the
machine.
n is the needle, w' the upper thread of the sewing machine. is the material to
which the button is to be fastened is the button itself. The case or the button holder
consists as shown by Figs. 4 and 5 in plan and longitudinal sections of two circular
discs d and d¹ of which d is journalled within the circular flange on tho disc d'.
Between these two discs d and d are journalled two or more jaws and h¹ guided
in one or more slots e of the disc d' so that said jaws may be adjusted in the slots e
and brought thereby more or less near one to the other according to the size of the
button to be sewn on. Figs. 6 7 and 8 show the disc d' as seen from above the
disc d being removed and the jaws h and h¹ adjusted at various distances one from
the other. In Fig. 8 the jaws and are adjusted for the smallest button r in
Fig. 7 for the largest button and in Fig. 6 for a button r of medium size.
The adjustment and displacement of the jaws is provided for by each jaw h
and carrying a stationary pin o and o' which gears into an oblique or curved slot p.pl
in the disc (Figs. 3 and 4). If now d' is rotarily displaced with regard to a by
turning the disc d' the jaws will approach one to the other or will move away one from
the other according to whether rotary movement is made towards the right or loft.
As soon as the jaws have reached the proper distance one can fix the discs d and d
together by means of the adjusting screws and e' so that the jaws are pressed at the
same time, the projecting edge a of the jaws (Fig. 5) which former is located between
the discs being nipped by the tightening together of the latter.
The upper disc d has a funnel shaped notch through which the needle passes. The
button holder set forth serves as a propeller of the material at the same time the jaws
as seen by Fig. 5 being toothed at the lower end thus entering the material b.
The necessary tension against the material is obtained by the spring of which
presses the button holder upon the material b, the button holder being pivoted at y.

page_text: When a button is to be insorted the holder is raised which is done by pressing
down the arm & pivoted at t. The bolder has then the position as seen in Fig. 1
dotted lines.
The propelling of the button holder is done by the guide (Figs. 2 and 3) which
is moved by the arm g' and the grooved cam disc y. With the device represented,
the holder which is fastened to the shaft e oscillates in the bearings LL' of the frame.
But instead of a reciprocating rotary motion the button holder may receive a to and
fro longitudinal motion as with the older constructions of the button holders.
The displacement being the amplitudo of oscillation is uljustable according to
the size of the button and the distance of the button holes one from the other.
Instead of two jaws and has shown one may also use three or more jaws
which may be adjusted one towards the other in the same manner as above
explained.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed 1 declare that what
I claim is
1. An adjustable button holder for button sewing machines having two dises d d
adjustable one towards the other which hold between them two or more jaws h h³
which by relative rotation of one of the dises on the other are brought more or
less near each other and may be fixed in place by the fixing of the discs for the
purpose set forth.
2. The construction of said device as a combined button holder and cloth presser
foot the jaws having teeth on their under faces substantially as and for the
purpose set forth.
