PROVISIONAL SPECIFICATION.
Improvements in and connected with Means for Covering Venetian
Blind Laths.
1 GEORGE WILLSHIRE JOHNS of 9 Ambler Road, in the Parish of Islington,
in the County of London Mechanic, do hereby declare the nature of this invention
to be as follows:-
My invention consists of an improved device for holding linen hollow
coverings (or linen envelopes,) and the like when subjected to strain on being filled
with wooden frames, as used and made under Letters Patent granted me
September 18th 1893, No. 17,527.
My plan is to form a base of wood or metal to which is attached a standard,
having an aperture or slot lengthways with the base, and large enough for the
insertion of the hollow linen covering or envelope. At one end of the slot through
the standard are two wedges for holding the hollow covering or envelope which is
passed through the aperture and cut at the end to form a flange on each side of
the slot, to be pressed by the wedges. The wedges are kept in position by guides
and connected with and operated by a lever attached to the standard.
A guide
for the hollow covering or envelope may be attached to the opposite end of the
aperture.
The principal feature in this improvement is the rapidity with which hollow
coverings or envelopes and the like can be filled with wooden frames.

Improvements in and connected with Means for Covering Venetian
Blind Laths.
I, GEORGE WILLSHIRE JOHNS, of 9 Ambler Road, in the Parish of Islington,
in the County of London, Blind Manufacturer, 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:—
My invention consists of an improved device for holding hollow coverings or
envelopes and the like made of linen or other material when subjected to strain on
being filled with wooden frames as used and made under Letters Patent grauted
me September 18th 1893, No. 17,527.
My plan is to form a base of wood or metal to which is attached a standard,
having an aperture or slot, lengthways with the base and large enough for the
insertion of the hollow linen or other covering or envelope.
At one end of the slot are two wedges for holding the hollow covering, which is
passed through the aperture and cut at the end to form a flange on each side of
the slot, to be pressed by the wedges. Or, instead of two wedges I may use two
metal clips, (which may be hinged) one on each side of the slot to press against the
flange and one wedge to press against the metal clips. Or I may press the metal

page_text: clips against the flange by means of pressure screws. The wedge or wedges are
kept in position by guides, and connected with and operated by a lever attached
to the standard. I may, however, dispense with the lever and operate the wedge
or wedges by hand. A guide for the hollow covering or envelope is attached to
the opposite end of the aperture.
The principal feature in this improvement is the rapidity with which hollow
coverings or envelopes and the lile can be filled with wooden or other frames.
Reference is to be bad to the accompanying drawings forming part of this
specification, wherein
Figure 1 is an elevation of a clamp the wedge or wedges of which are operated
by a lever.
Figure 2 is an elevation of a standard to support the guide.
Figure 3 is an elevation of a clamp the wedge or wedges of which are operated
by hand.
Figure 4 is an end view of Figure 1.
Figure 5 is an end view of Figure 3.
Figure 6 shows two pressure screws which may be used to press the flanges of
the material to be held instead of the wedges shown in Figures 1, 3, 4 and 5.
Figure 7 is an end view of Figure 2.
Figure 8 is a plan of Figure 2.
Figure 9 is a plan of Figure 5.
Figure 10 is an edge view of a metal plate (which may be hinged) used under
the wedge or wedges or screws in Figures 1, 3, 4 and 5 to grip the material to
be held.
Figure 11 is a pressure screw shown in Figure 6.
Figure 12 is an end view of guide shown in Figures 1, 2, and 3.
Figure 13 is a side view of perforated guide shown in Figures 1, 2, and 3.
Figure 14 is a plan of Figure 6.
The same letters of reference indicate like parts in all the figures.
In Figure 1, a is a lever; bis a wedge; c is a guide or holder; d is a standard;
e is a connection between a and b.
In Figure 6, f and f1 are pressure screws.
In Figure 9, g and g¹ are metal plates shown in Figure 10.
In Figure 13, and h¹ are perforations to enable the hollow covering or envelope
when filled to be more readily passed through the guide.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what 1
claim is ;
The herein described device for holding hollow coverings or envelopes and the
like made of linen or other material when being filled with wooden or other frames,
substantially as specified.
Dated this 5th day of May 1896.
