page_text: Figure 22 shows an elevation of a pair of top and bottom cramps the pin being
fastened permanently in the bottom cramp.
Figure 23 is a plan of figure 22.
Figure 24 shows a pair of cramps with the pins hung on pivots to work as
represented.
Figure 25 is a plan of figure 24 at d d—d d.
Similar letters refer to similar parts throughout the various views.
The means adopted for making the joint at figures 1-2 and 3 are what is
technically termed mortice and tenon-a is the mortice 6 is the tenon, the holes c
are for fastening the tenon in the mortice by means of the pins d.
To stretch a pair of trousers as shown at figure 3 the trousers would be placed
between the cramps e and f the expanding arms g would be placed in the position
shown at figurę 1 with the ends h fitting into the slots in the top cramp, the
expanding arms would then be flattened out to the position shown at figures 2
and 3, thus stretching the trousers. The rule-joint expander illustrated at figures
4 and 5 is provided with pieces at j to form the lip corresponding with / figures 2
and 3, these pieces are put on, to raise the projecting part of joint k above the
trousers: when fixed as represented at figure 4 and pushed down into the position
represented at figure 5 the trousers would be stretched.

The rule-joint expander represented at figure 6 works in a similar
figures 4 and 5 instead however of seperate pieces screwed on as at j I cut the
two sides of the expander curved as represented at l. The plan figure 7 represents
the rule-joint expander figure 6 in action stretching the trousers, this plan will
also explain the action of figure 5.
The knuckle joint arrangement shown figures 8-9 and 11 works in the manner
illustrated, the two halves of the expander are provided with studs o: after the
two halves m, n are pressed to their full extent as represented at figures 9 and 11,
loops similar to figure 10 are passed on to the studs o as represented at figures 9
and 11. The cramps are formed of a top piece and a bottom piece very similar to
the cramps illustrated in my specification N° 16,777 year 1884 but with variations
in the arrangement for fastening the two parts of the cramp together.
Figures 12, 13 and 14 represent three different methods of arranging the slots
or openings to receive the screws: the object of making the top half of the cramp
with slots in as represented at figures 12, 13 and 14 is for the greater convenience
in putting the trousers between the cramps and for greater convenience in removing
the top half when the trousers have been stretched. Figures 15 and 16 represent
a way of gripping the cramps without the use of pins and fly nuts, the action of
the spring P presses the flanges g against the cramps; by pressing the handles r
nearer to the centres, the flanges g would be released from the cramps.
Figure 17 is a similar arrangement to figures 18 and 19 with difference in the
fixing of the spring as shown at t, the sides of figure 15 are crossed, the sides of
figure 17 are not crossed. Figures 18 and 19 show another way of gripping the
cramps together the spring w giving the required pressure as indicated.
Figure 20 shows a pair of trousers fixed ready for stretching, the cramps are
pressed together by the screws w, a piece of metal or other substance is secured
to the cramps. A hole is provided by means of which the piece of metal can
be hung on a nail in any convenient place. A hook being secured to the bottom
cramps and the weight a a being hung on to it, the trousers would be stretched.
Figure 21 shows a similar arrangement to figure 20 excepting that the top pair
of cramps are pressed together by means of the clip.
Figures 22 and 23 show a top and bottom cramp put together; the screw pins
being secured permenantly into the bottom half of cramp, the top half corresponding
with the detailed representation figure 13. Figure 24 shows the top and bottom
halves of cramp connected, the screw-pins being hung on a pivot, the top half
corresponding with the detailed representation Figure 12.
Figure 25 is a sectional plan of bottom cramp on the line d d—d d figure 24 with
pins disconnected and dotted in,

page_text: 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
1st The combination of a mortice and tenon jointed expander with a pair of
cramps at each end for the purpose of stretching trousers, as illustrated and
described.
2nd The combination of a rule joint expander with a pair of cramps at each end
for the purpose of stretching trousers, as illustrated and described.
3rd The combination of a knuckle joint expander with a pair of cramps at each
end for the purpose of stretching trousers, as illustrated and described.
4th The combination of either of the top halves of cramps as shown at figures 12,
13 and 14 connecting with bottom halves for the purpose of stretching trousers.
5th The scissors shaped grips or clips as shown at figures 15, 16 and 17 for the
purpose of securing the top and bottom halves of cramps on to the trousers.
6th The grip or clip shown at figures 18 and 19 combined with two pairs of
cramps and a weight and hook for the purpose of stretching trousers.
7th The arrangement of cramps as represented at figures 20, 21, 22, 23, 24
and 25 for the purpose of gripping trousers ready to receive an expander by
means of which combined with the said cramps or any of them the trousers would
be stretched,
