page_text: PROVISIONAL SECIFICATION left by William Clark at the Office of the
Commissioners of Patents, with his Petition, on the 12th January
1868. A communication from abroad by Jean Jacques Bourcart,
Engineer, of 29, Boulevart St. Martin, Paris.
I, WILLIAM CLARK, of 58, Chancery Lane, in the County of Middlesex,
Engineer and Patent Agent, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN WINDING OR COPPING FRAMES," to be as
follows:
This Invention relates, 1st, to the employment of a fixed apparatus for
lowering the faller to the point of the spindles in winding or copping machines,
and at same time stretching or keeping in a fixed position the chain, cord, or
other intermediate apparatus before the pointing, and during the latter period
of the motion of the carriage only.
2ndly, in the application of a double pulley or variable connection between
the faller and the ratchet pointer situated on the shaft of the drum spindles,
in order that the course of the faller shall be always in the required
relation with the number of turns of the spindles during the pointing.
3rdly, in the employment as an intermediate agent between the apparatus
conducting the faller (rule or copping plate) and the faller of a combination of
parts, knee-jointed, and constructed in such manner that the projections on
the spindle and the spaces traversed by the faller may be proportionate to the
variations of the conducting apparatus.
A, Fig. 1, of the annexed Drawings, represents the carriage; B, vertical

page_text: sliding support fixed to said carriage; C, similar support; E, part sliding in C,
and having a guide groove 1, for receiving a friction roller carried by part
H; D, roller resting on M and sliding in M; G, knee jointed arm connected
to E, and turning on joint L. H, arm fixed to the faller, having a friction
roller sliding in and fixed to k; I, faller fixed to K, K, shaft of faller;
L, rod for stopping the pointer; M, rule or copping motion; i, guide groove in
Fig. 2; K is the shaft of the faller; R segment of pulley fixed to K; T, scroll
or pointer barrel; y, shaft of spindle drums; F¹ chain fixed at R and N; F,
chain fixed to P and T.; S, catch plate; U, finger fixed on S; G, rod fixed to
Z; Z, frame; q, hinge; q', fork of rod G.
1st arrangement.-When the carriage has almost completed its course, u
Fig. 2, comes in contact with q', and is caused to turn on y, and as I is fixed to y
it is also obliged to turn and wind up the chain F, which, by the agency of
parts N, P, R, causes the faller to descend as low as part G will allow, this only
takes place before the pointing and during the latter period of the motion of
the carriage.
2nd example, Fig. 2.-In self-acting arrangements there is generally but one
chain passing from T to R, over a single pulley in the same position as N, P.
By means of pullies N, P, and two chains F, F, I may increase or diminish the
pointing at will by changing the relative diameters of pulleys N and P,
'because, while the faller R, K, has the 'same motion, parts -T-and y, will make
'a greater 'ör less 'number of turns.
3rd example, 'Fig. 1.-The variation of rule M'are-required to be transmitted
to faller I, for this purpose the roller D receives and transmits them vertically
'to G; which is drawn by the carriage A, and slides on M ; during the winding
'part, Ġ raises or lowers E, by turning on 'joint, and by means of slide'i turns
part H on K, and consequently moves faller J. When slide iis perpendicular
to 'the 'motion of 'D from 'G and E, it is evident that the projection of faller I on
the spindle will be the same or in proportion to the distance traversed by 'D.
The advantages resulting from these improvements are manifest in practice
from the exactitude imparted thereby to the motion of the fallers of copping
or winding machines, as also in 'the pointing.
