page_text: I THOMAS SINGLETON of Bank Top Works, Over Darwen in the county of Lancaster,
Machine Maker, do hereby declare the nature of this Invention to be as follows:-
My weighting motion consists of a neck or ruffle, at each end of the beam, on each
ruffle is a gear wheel, gearing with a second gear wheel attached to a second loose
neck on a fixed stud or shaft, a chain or rope is attached to a spring, the spring
being fixed to the frame of the loom, the chain passes several times around the neck
of the beam, then several times round the loose neck, to an ordinary weighted lever,
or levers and weights, by this arrangement, the friction on the two necks tightens
against each other, so as to dispense with heavy weights; or instead of the chain, I
may apply two friction clips to the necks, adjustable to slacken or tighten by means
of bolts and springs. My improved loose reed motion is as follows, I employ a long
curved blade spring, to which I attach the L bracket or heater which comes in
contact with the duck bill (or its equivalent) for stopping the loom when the shuttle
fails to box, the spring from the knocking off lever is secured to an adjustable
bracket, on the blade spring for regulating purposes, and the blade spring insures a
back and front tension, and is preferably attached to the front cross rail, and curves
upwards, and abuts against a regulating bracket on the breast beam, and recedes
when tupped or struck, from end to end, and no breakage or strain can occur, when
working as ordinary; the pick is put in firm and secure.
My improved spring buffer consists of a blade spring secured to the top cross
rail, or other part of the loom, and comes forwards towards the picking stick, carries

page_text: a buffer of leather, wood, or other suitable substance, so as to check the picking arm
before the end of the throw, and after it has spent its power, thus saving the picking
stick, picking strap or band, and preserving the picker, a steadying bracket may be
attached to come in contact with the spring to steady it, and prevent vibration, a
similar appliance may be used with advantage to underpick looms.
Dated this Tenth day of February 1887.

regulating the tension on the warp beam.

Fig. 7 shows a plan of my improved spring buffer, for preserving the picking
sticks, bands and the like.
A is a neck or ruffle at each end of the beam E, on each ruffle is a gear wheel B,
gearing with a second gear wheel C, attached to a loose neck D, (so as to allow for
oscillation) on a fixed shaft or stud F, a chain or rope G is attached to a bracket or
spring H, the spring being fixed to the frame of the loom J, the chain or rope passes
several times around the neck A of the beam E, then several times round the loose
neck D, to an ordinary weighted lever or levers K and weights L, by this arrange-
ment, the friction on the two necks tighten against each other, and is so effective as
to dispense with heavy weights; or separate chains or ropes to each ruffle or neck
may be used see Fig. 3; or instead of the chain I may apply two clips M to the
necks A and D, adjustable by means of a bolt N and spring P, see Fig. 4.
My improved loose reed motions (see Figs. 5 and 6) I employ a long curved blade
spring R, to which I attach the L bracket or heater S, which comes in contact with
the duck bill S¹ (or its equivalent) at each pick of the loom, and when the shuttle
fails to box, the spring T from the knocking off lever T¹ is secured to an adjustable
bracket T preferably on the blade spring R, for cheapness, and so as to be easy of
adjustment, and to increase the elasticity of the spring T, by partially utilizing the
elasticity of the spring R; the blade spring is preferably attached to the front cross
rail W, and curves upwards and abuts against a bracket or bolt W¹, on the breast
beam, and recedes when tupped or struck, and no breakage or strain can occur when
working as ordinary; the pick is put in firm and secure.

page_text: My improved spring buffer (see Fig. 7) consists of a blade spring X secured to
the top cross rail of the loom, and comes forwards towards the picking stick Z, and
carries a buffer Y of leather, wood, or other suitable substance so as to check the
picking arm before the end of its throw, and after it has spent its power; thus
saving the picking stick, picking strap, or band, and preserving the picker.
A steadying bracket may be attached to come in contact with the spring to steady
it and prevent vibration.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. For regulating the tension--on the warp beam, the use and employment of
chains, ropes, or clips, or other frictional appliances upon fast and loose necks, which
are geared together for the purposes shown and described.
2. In my improved loose reed motion, the curved blade spring R, carrying
heater S with adjustable bracket T2 and spring T as and for the purposes shown and
described.
3. The use and employment of a spring buffer for checking the picking stick or
arm as and for the purposes shown and described.
