Improvements in or relating to Stands for Sewing Machines.
We, DANIEL JONES, Managing Director, and HENRY PATTMAN TRUEMAN,
Works Manager, both of The Two-reel Lock-stitch Sewing Machine Company,
Limited, of 62 Albion Street, Birmingham, in the County of Warwick, do hereby
declare the nature of this invention to be as follows:-
This invention has reference to improvements in or relating to stands for sewing
machines of the kind in which an iron framework carrying the treadle and flywheel
forms the support for a wooden table on which the machine itself is mounted, and
which may be provided with one or more sets of drawers the object being to
construct such stands in a better and more economical manner than heretofore.
According thereto the end frames are cast with holes adapted to readily receive
the pins or bolts employed for connecting the parts of the frame together and with
notches adapted to readily receive the screws employed for screwing on the wood
top, thereby avoiding the expense of forming holes for these purposes by drilling.
The stretcher bar or cross brace which connects the end frames is also formed by
casting, with holes for bolts and with recesses for bearings, so that the bearings for
the treadle and the fly wheel, can be attached without the necessity of drilling holes
for this purpose.
According to one arrangement a V-shaped groove or grooves is or are cast in the
cross brace, and in these grooves centre point or other suitable pin bearings adapted
to enter recesses in the treadle or flywheel crank are secured by eye bolts which
embrace the pin bearings and pass through that part of the cross brace in which the
grooves are formed. The shanks of the eye bolts are screw threaded and provided
with nuts. When these nuts are slackened, the pin bearings can be adjusted
endways in the grooves but when they are tightened up, the pin bearings are
held firmly in the V grooves. According to another arrangement there is
provided at the necessary places, bearings consisting of tubes which may be split if
found desirable, and of any convenient length for example three times as long as
the diameter of the treadle or crank shaft to which they are applied. At or about
the centre of the outside of each bearing a spherical surface is provided adapted to
engage in oppositely arranged perforations formed in approximately U-shaped
retaining pieces that are secured in holes or recesses cast in the cross brace itself
by bolts or screws.
These retaining pieces may advantageously be made of strips
of sheet metal. Each of these strips is perforated near its ends, and is then bent to
an approximately U-shape so as to bring the perforations which form rings or cups
opposite to each other. The bottom of the U-shaped strip is bent to a more or less
angular shape so that in end view it is of wedge form similar to that of the recess
in the cross brace into which it is to fit. A set screw that passes through the
recess in the cross brace works in a screw threaded hole in the U-shaped retaining
piece so that on the screw being turned in one direction the retaining piece is
drawn into the recess and the perforated parts are caused to close upon the
spherical part of the bearing.
The cross brace is also provided with a lug adapted to hold or support a tool box
or other attachment. The wood top of the table is secured to the iron frame by
means of screws engaging with the herein before described notches cast in the end
frames.
The drawers are attached to the stand in the following manner.
Screw threaded holes are formed in the wooden table top (or blocks formed with
screw threaded holes are attached thereto) and into these holes which may be four

page_text: in number, are screwed the upper ends of a corresponding number of depending
rods the arrangement being such as to allow of one or more drawers passing between
them. The lower ends of the rods are formed with internally screw threaded holes.
A shelf having holes formed through it is fixed to the lower end of the depending
rods by passing the externally screw threaded ends of another set of depending rods
through the holes in the shelf and screwing them into the internally screw threaded
holes in the lower ends of the first set of depending rods. In this manner a series
of shelves can be attached to the stand and upon them between the depending rods,
drawers are mounted and arranged to slide upon the same, being guided by means
of a pin, spline or feather arranged to work in a groove. The lowest shelf of the
series is secured to the last set of depending rods by knobs formed with screw
threaded stems adapted to engage in the internally screw threaded holes formed in
the ends of the lowest set of depending rods.
When the table top is provided with an extension leaf, the said leaf may be
attached to the main table according to this invention by means of hinges con-
structed with wire hinge pins having eyes through which screws are passed for
attaching the hinges to the table top or to the leaf as may be desired. Hinges of
this description can be very cheaply made.
The extension leaf is or may be supported by a bracket which is provided with
pins.about which it is adapted to turn the said pins being arranged to work in holes
or recesses formed in the table top and in the first drawer shelf respectively. This
bracket is acted upon by a spring the arrangement being such that when the
extension leaf is raised into a horizontal position, the said spring will cause the
bracket to assume its open position and support the extension leaf. A wedge stop
is fixed on the under side of the leaf so as to engage with the bracket when the
same is moved into its open position by the spring.

Improvements in or relating to Stands for Sewing Machines.
We, DANIEL JONES, Managing Director, and HENRY PATTMAN TRUEMAN,
Works Manager, both of The Two-reel Lock-stitch Sewing Machine Company
Limited of 62 Albion Street, Birmingham in the County of Warwick do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
This invention has reference to improvements in or relating to stands for sewing
machines of the kind in which an iron frame work carrying the treadle and flywheel
forms the support for a wooden table on which the machine itself is mounted and
which may be provided with one or more sets of drawers the object being to
construct such stands in a better and more economical manner than heretofore. As
we will now proceed to fully explain by reference to the accompanying drawings in
which
Fig. 1 shews the elevation of an end frame for a sewing machine constructed
according this invention.
Fig. 2 is a plan view of Fig. 1 partly in section on the line A B.
Fig. 3 is a front elevation of the stretcher bar or cross brace.
Fig. 4 is an end elevation of Fig. 3.
Fig. 5 is an enlarged view of the lugs aa of Fig. 3.
Fig. 6 is an enlarged view of the same lugs a a in end elevation of Fig. 4.

page_text: Fig. 7 is a sectional elevation of a tubular bearing with spherical centre portion.
Fig. 8 is an elevation of a U shaped clip with bearing shewn in dotted lines and
Fig. 9 is a plan view of the same.
Fig. 10 is an enlarged view of the brace at the part 6 of Fig. 4 shewing the clip
and bearings in position.
Fig. 11 is a front elevation of the sewing machine stand complete.
Fig. 12 is an elevation of one end of a table top with bracket, leaf, and drawer
shelves.
Fig. 13 is a modified form of the pillars for supporting the drawer shelves.
In constructing a sewing machine stand according to this invention the end
frames are formed with bolt holes cc cc Fig. 1 and with notches d d d d Fig. 2.
Holes are or may be provided at ee Fig. 1 for the reception of rivets or studs
adapted to carry rollers or wheels.
The brace Fig. 3 and Fig. 4 is also provided with holes ffff. At b b Fig. 3
and Fig. 4 the brace has transverse bolt holes at the bottom of the U shaped
recesses. This portion of the brace is more clearly shewn in Fig. 10.
At a a Fig. 3 the brace is provided with V-shaped grooves having transverse
bolt holes gg as may be clearly seen in Figs. 6 and 6. The tubular bearing
shewn in Fig. 7 is formed with a curved or spherical outer portion and is provided
with a small boss at or about its centre, through which said boss is or may be
drilled an oil hole for the purpose of lubricating the shaft revolving therein.
The clip Figs. 8 and 9 has apertures i adapted to retain the bearing Fig. 7 by
embracing a portion of the spherical surface.
The oil hole boss projects into and through the upper of these apertures as shewn
in Fig. 10. The clip is preferably fastened in its recess on the brace by a bolt
and nut as shewn in Fig. 10 instead of screw threading the clip as described in
our Provisional Specification. The table top has screw threaded holes formed in
its under surface as at m Figs. 11 and 12.
The depending pillars have external screw threads formed on their upper ends
and internal screw threads in their lower ends. The depending pillars may also be
formed with holes at each end, these pillars may be connected together by means of
double ended screws, or ordinary dowels as shewn in Fig. 13.
Shelves o are placed between the pillars, and drawers p are or may be arranged
to slide upon the shelves as shewn in Fig. 11.
The lower shelf is retained in position by screw knobs as shewn at g Figs. 11 and 12.
The extension leaf r is supported by a brackets Figs. 11 and 12.
The brackets has pins t the upper of which turns in a hole in the under side of
the table top; and the lower in a hole provided in the-shelf o.
An extension of the lower pin t¹ carries a spring tone end of which abuts
against one of the depending pillars or other fixed part of the stand; and the
other end presses the bracket outwardly, so that on lifting the extension leaf the
bracket automatically springs into position shewn in Figs. 11 and 12.
The outward movement of the bracket is preferably arrested by means of a block
or wedge u fixed on the leaf as shewn in Fig. 12.
The various parts are combined and arranged as shewn in Fig. 11. The method
of erecting or assembling the stand is or may be as follows. Reference may be
made to Fig. 11. The fly wheel and crank v, and treadle w, are fitted to the
brace y by means of the bearings and fastenings described in connection with
Figs. 5. 6. 7. 8. 9. 10. The brace is then placed between the end frames Z and
bolted thereto. The wood top is fastened to the end frames by screws passing
through the notches d shewn in Fig. 2. The pillars are screwed into the holes of
the top and a shelf o is secured to the lower ends of the pillars by another series of
pillars or knobs q as shewn. The bracket (when used) is inserted between the
table top and the first shelf as shewn. A collar a on the crank prevents endway
motion of the shaft in its bearings. Endway motion of the treadle bearings is
taken up by sliding the pins in Figs. 5, 6 and 6 through the eye bolts 1.

page_text: Bearings and clips as Fig. 10 may be used for treadle bearings instead of the pins
and eye bolts shewn in Figs. 5. 6 and 6A.
We are aware that sewing machine stands have been constructed having notches
and holes formed in them by casting which said notches and holes were adapted to
receive bolts and screws for holding the parts together; we therefore make no
exclusive claim for this as a method of construction generally, but define our
invention to consist in the particular construction and combination of the parts
substantially as herein described and illustrated.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that
what we claim is :-
1. In a stand for sewing machines. The employment of a stretcher or brace,
formed with recesses adapted to receive swivel bearings, and clips, as and for the
purpose described in connection with Fig. 10 of the accompanying drawings.
2. In a stand for sewing machines. The construction and use of a bearing or
bearings having spherical enlargements, adapted to swivel or turn about in clip or
other similar holders, substantially as and for the purpose described in connection
with 7. 8. 9 and 10 of the accompanying drawings.
3. In a stand for sewing machines. The use of a table top having screw
threaded holes formed in its under side adapted to receive depending supports for
the drawer shelves as described and illustrated in connection with Fig. 12 of the
accompanying drawings.
4. In a stand for sewing machines. Depending drawer supports having an
external screw thread at one end, and an internal screw thread at the other as and
for the purpose described.
