Commissioners of Patents, with his Petition, on the 21st October 1854..
I, JULIAN BERNARD, of Club Chambers, Regent Street, in the County of
Middlesex, Gentleman, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR STITCHING" to be as follows:-
The first part of this Invention consists in balancing, or nearly so, the arm,
slide, or lever which actuates the needle or needles of stitching machines,
whether such arms actuate the needle or needles directly or otherwise; one
way in which this may be accomplished by increasing the part or side of the
centre, marked A in the tracing, Figure 1, hereunto attached.
The second part consists in imparting a lateral motion to arms for actuating
the needles of stitching machines, whether such arms be worked on the prin-
ciple illustrated or otherwise. Figure 2 on the tracing illustrates an example
of this part of my Invention, where A marks the bracket, and B the stud,
which may also be placed upon a slide.
The third part of my Invention consists in attaching or connecting one or
both of the jaw pressers or arms for feeding or travelling the material to the
arm which actuates the needle or needles...B, at Figure 1, and C, at Figure 2,
illustrate modifications of this part of my Invention, and I place such arms or

page_text: jaws upon the same centre as the bracket; the spring arm B, Figure 1, is
made to nove laterally or otherwise with the bracket, while the jaw C,
Figure 2, is secured fast upon the centre B.
The fourth part of my Invention consists of imparting motion to the jaw or
feeder by the arm A, Figure 1, whether directly or in combination with other
means employed for the purpose. Figure 3 shows an eccentric, on which the
pin A, in Figures 2 and 3, acts as the arm moves; the eccentric cam or pin is
made to act upon the spring lever C by being secured and placed in proper
position in the bed plate for that purpose. Figure 4 shows another view
of part of the arrangement, and C marks the spring lever on which the
eccentric acts.
The fifth part of my Invention consists of the use and application of a
slotted lever, cam, or slide in connection with a pin and roller, and I sometimes
place the said slotted slide on a centre, so as to be easily actuated by any con-
venient adjusting arrangements. D, at Figure 1, marks the slotted lever,
which I make curved, as shewn, which has the effect of lessening the friction
of said roller; E marks the centre of motion, and F marks the roller.
The sixth part of my Invention consists of moving or travelling stitching
machines upwards or laterally in the case, stand, or table which may contain
them, and the mode I adopt from preference is illustrated at Fig. 5, where
A marks a slide, which moves vertically, and C the leg of the stand or table,
shown in section; on the top of the slide is placed the table or platform which
carries the machine, and moves up and down as desired. By these means the
top D of the table or platform may be quite flat and hinged, so that when
turned down, the machine is wound up by the handle F; and I place and
secure the arrangements for giving motion to the machine on the slide A,
and the arrangements for actuating it may be either wound up before raising
the machine or afterwards; and I sometimes place stitching machines in the
form of a drawer, so that they may slide in and out of a table, and I place or
dispose a work box or drawer in side part of the table, and cover the same
with silk, velvet, or other ornamental or fancy material. Figure 6 shows a
sectional elevation of these improvements; where a marks the moveable table,
screwed to the slide b; C represents the top framing of the stand or table;
and d, the drawer; and e, e, the arrangements and place of the work-box;
and I sometimes make the top of the table into a writing desk, or put or
combine a suitable writing stand or convenience for writing in the stand or
table of such machines.
The seventh part of my Invention consists of an improved fly wheel for
stitching machines, the object of which is to enable the operator to work the

page_text: machine either by hand or power, at discretion. The half, or part A, at
Figure 7, is loose upon the shaft D; but the other half B, and the clutch C,
are fast upon said shaft. When the operator wishes or desires the power
to drive the machine, he puts the clutch box in contact with the part A, and
when he wishes it not to act, withdraws the clutch; the machine then ceases
to act. If desirable, he may work it by the handle E.
The eighth part of my Invention consists of roughening or marking a
number of circumferential grooves in the bed plate of the machine, or that
part on which the material bears, or is pressed or lead. I also place or indent
circumferential grooves in the jaws of the pressers or travellers. Figures 8
and 9 illustrate this part of my Invention.
