PROVISIONAL SPECIFICATION.
Improvements in or connected with the Pantagraphs of Embroidery
Machines.
I, FREDERICK JAMES PERRY, of Boulevard Works, Radford, in the Town and
County of the Town of Nottingham, Manufacturer, do hereby declare the nature
of this invention to be as follows:-
The invention relates to improvements in, or connected with, the pantagraphs
of embroidery machines, with a view to prevent the injury which has hitherto
resulted to the patterns by the insertion of the pantagraph point therein on every
stoppage of the machine.
According to my present invention I avoid this insertion of the pantagraph
point into the pattern, and in lieu thereof I provide means whereby the panta-
graph point can be securely held in any position with relation to the pattern
without permitting it to come actually in contact therewith.
For this purpose I pin-joint to one of the parallel levers of the pantagraph,
namely, that one which is jointed to the machine frame, a pair of locking bars,
one of such locking bars being passed through a guide carried by the pantagraph
operating arm, and the other through a guide fixed to the machine frame.
of such guides is provided with clamping means to enable these locking bars to
be clamped securely in any position desired.
Each
The pantagraph operating arm, in addition to carrying the ordinary pointer,
also carries a blunt stud or finger, very slightly longer than the pointer, so as
to prevent the latter ever coming into contact with the pattern. By these means
the operator is, as heretofore, enabled to fix the pantagraph in any position
in which work may be suspended, without pushing the pointer into the pattern
and thereby injuring the latter.

COMPLETE SPECIFICATION.
Improvements in or connected with the Pantagraphs of Embroidery
Machines.
I, FREDERICK JAMES PERRY, of Boulevard Works, Radford, in the Town and
County of the Town of Nottingham, Manufacturer, do hereby declare the nature
of this invention, and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
---
The invention relates to improvements in or connected with the pantagraphs
of embroidery machines with a view to prevent the injury which has hitherto
resulted to the patterns by the insertion of the point of the pantagraph operating
lever on every stoppage of the machine.
According to my present invention I avoid the insertion of the point of the
pantagraph operating arm into the pattern, and in lieu thereof I provide means
whereby the pantagraph point can be securely held in any position with relation
to the pattern without permitting it to come actually in contact therewith.

page_text: I will describe my invention by the aid of the accompanying drawings, in
which:
Fig. 1 is a front view of parts of the fixed framing and of the movable frame
of an embroidery machine showing the pantagraph and my improvements applied
thereto, and Fig. 2 is an edge view of part of the pantagraph operating lever.
a is a portion of the fixed main frame of the embroidery machine. 6 is the
movable frame which carries the fabric to be embroidered. This latter frame is
supported in the well known manner (not shown) to enable it to be moved in any
direction according to the design desired to be produced. c, c are the parallel
levers of the pantagraph, the lever c being connected at 2 to the fixed framing a,
whilst the lever is attached at 3 to the movable frame b. is the pantagraph
operating arm.
According to my invention I pin-joint at d to the lever c, that is to say, to
that one of the parallel levers of the pantagraph which is pin-jointed to the fixed
framing of the machine, a pair of locking bars d', d², one of such locking bars,
the bar, being passed through a guide consisting of a part al fixed to the
main frame and a top plate a², which is capable of being tightened against the
locking bar, or of being loosened to free the latter, by a fly nut a working
on a screw a fixed to the part a¹. The other locking bar d² is passed through
a guide formed on the pantagraph operating arm by means of a plate co fixed
at one end thereto and acted upon at the other end by a screw and fly nut c¹
to fix and release the locking bar & as may be required.
It will be evident that the guides and locking means for the locking bars ď ď
may be of any other suitable character.
The pantagraph operating arm 4, in addition to carrying the ordinary pointer c³,
also carries a blunt stud or finger every slightly longer than the pointer c³, so
as to prevent the latter ever coming into contact with the pattern.
By the means hereinbefore described the operator is, as heretofore, enabled
to follow the pattern by means of the pointer 8 and, by means of the screws ca
and nuts and locking bars, to fix the pantagraph in any position in
which work may be suspended without pushing the pointer through the pattern
into the board e carrying the latter and thereby injuring the pattern.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. The combination with the pantagraph of an embroidery machine, of locking
bars pin-jointed to that one of the pantagraph levers which is pin-jointed to the
main fixed frame, a guide fixed to the main frame through which one of said
locking bars is passed, a guide fixed to the pantagraph operating arm through
which the other locking bar is passed, and means for fixing such locking bars
within the guides and for freeing the same therein, substantially as herein set
forth.
2. The combination with the pantagraph of an embroidery machine, of locking
bars pin-jointed to that one of the pantagraph levers which is pin-jointed to
the main fixed frame, a fixed guide and a guide on the pantagraph operating arm
through which said locking bars are passed, means for fixing and releasing said
locking bars in their guides, and a blunt stud or finger on the pantagraph operat-
ing arm in addition to the ordinary pointer and slightly longer than the latter
to prevent injury to the pattern by the pointer, substantially as herein set forth.
