page_text: forward until the ends of the lower bar or jaw b of the fixed clamp or cramp C³ pass
or drop into the slots T, T in the top front ends of the sides A, A. On revolving
the screw D by means of the pinion wheel P and spur wheel S the nut or block K
will travel along and on coming in contact with the lower bar or jaw b of the
sliding clamp C will push it along thereby stretching the leather to any required
degree of tension and the catches or clicks f, f, engaging with the teeth tt will hold
the clamp or cramp C² in any position left by the nut or block K thus keeping the
leather in a stretched condition for any length of time.
When the leather has been stretched as much as desired the motion of the pinion
wheel P is reversed until the nut or block K has passed clear of the grooves E E
or E' E' to enable the rack with the leather stretched in it to be lifted from the
machine by drawing the rack back until the ends of the sliding clamp or cramp C²
come opposite the grooves E E or E' E' through which they can be lifted leaving
the machine ready for another rack with a second piece of leather to be stretched
placed in it.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. The combination of a pair of sides containing two vertical and two longitudinal
grooves and one slot in each with a pinion and spur wheel and screw and sliding
nut or block surrounding the screw substantially as described.
2. In a stretching rack the combination of a fixed clamp or cramp C' with the two
bars or rails D', D and the sliding clamp or cramp C² substantially as described.
3. In a fixed clamp or cramp and a sliding clamp or cramp the combination of a
bar a and a lower bar or jaw b having a groove e, and an upper bar or jaw c
connected to a screws and having a projection p substantially as described.
4. In a leather butt or hide stretching machine the combination of the
followingA pair of sides, two vertical and two longitudinal grooves and one slot
in each, a fixed clamp or cramp bolted to two bars or rails and adapted to fit the
slots, a sliding clamp or cramp adapted to slide on the bars or rails and in the
upper longitudinal grooves, a nut or block adapted to move or slide in the lower
longitudinal grooves and engage with the sliding clamp or cramp and surrounding
a screw connected with a spur wheel gearing with a pinion wheel on one end of a
shaft passing through bearings on one of the sides substantially as described.
