Year: 1864

page_text: LETTERS PATENT to Charles Hartley, of Salford, in the County of
Lancaster, Machinist, and Thomas Hall, of the City of Manchester,
Machinist, for the Invention of "IMPROVEMENTS IN LOOMS FOR WEAVING."
Sealed the 16th May 1865, and dated the 26th November 1864.
PROVISIONAL SPECIFICATION left by the said Charles Hartley and
Thomas Hall at the Office of the Commissioners of Patents, with their
Petition, on the 26th November 1864.
I, CHARLES HARTLEY, of Salford, in the County of Lancaster, Machinist,
and THOMAS HALL, of the City of Manchester, Machinist, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN LOOMS FOR WEAVING,'
to be as follows:-
Our first improvement consists in the particular shape of the grooved cam
or tappet plate, for raising or depressing the healds of swivel and other looms,
and keeping them open so long as the open shed is required, or we employ
a guide or strap of the same shape as the grooved cam or tappet plate,
connected with levers to move the treadles. Friction rollers are employed to
work in the internal slots or grooves. For the same purpose we employ a
crank wheel or pulley with a stud keyed on the loom crank shaft end.
By means of these improvements more dwell and rest can be given than
heretofore, and any number of healds may be operated upon.

page_text: Our second improvement consists in the application of a vibrating crank
to lift and depress the streamer rods connected to the top and bottom jacks,
a pattern chain moves the selected catches on to the vibrating crank for
raising and depressing the healds attached to the jacks.
The next improvement is in the catches jointed to the streamer rods, one of
these catches is acted upon by a suspended pusher worked by a pattern chain
or lags with pegs.
Another of our improvements consists in dispensing with the lever and
pusher, and applying the pattern chain or the lags and pegs, to the upper end
of the catch. We next improve the streamer rods by moving the studs for
the catches more forward and placing ribs upon them for guides and bolts, we
also apply cross bars to keep the rods in their places. The above mechanism
may be applied to work any number of shuttle boxes, or the taking up
motion.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles Hartley and Thomas Hall in the Great Seal Patent
Office on the 25th May 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, CHARLES
HARTLEY, of Salford, in the County of Lancaster, Machinist, and THOMAS
HALL, of the City of Manchester, Machinist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of November, in the year of our
Lord One thousand eight hundred and sixty-four, in the twenty-eighth year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said Charles Hartley and Thomas Hall, Her special license that we,.
the said Charles Hartley and Thomas Hall, our executors, administrators,
and assigns, or such others as we, the said Charles Hartley and Thomas
Hall, our executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
LOOMS FOR WEAVING," upon the condition (amongst others) that we, the said
Charles Hartley and Thomas Hall, our executors or administrators, by an
instrument in writing under our, or their, or one of our or their hands and
seals, should particularly describe and ascertain the nature of the said Inven-.

page_text: tion, and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Charles Hartley and Thomas
Hall, do hereby declare the nature of our said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained in
and by the following statement (that is to say) :-
Our Invention consists:-First, in a grooved cam or tappet plate of an
improved shape for working the healds of looms.
Secondly, in an improved combination of machinery consisting of vibrating
cranks, pattern chains, and selecting fingers, or pushers, for raising and
depressing the healds to form the shed.
Thirdly, in jointing the streamer rods or catches to the jacks for working
the healds.
Fourthly, in applying the pattern chain or other equivalent to the double
catch jointed to the streamer rod of index machines.
And, fifthly, in an improved mode of constructing and arranging streamer
rods.
1
And in order that our Invention may be fully understood and readily
carried into operation, we will proceed to describe the accompanying Sheet
of Drawings, reference being had to the figures and letters marked thereon.
Figure 1, is an end elevation; and Figure 2 a front elevation of the framing
of a loom, to which our first and second improvements are applied.
a, is the crank shaft; b, the top jacks; c, the bottom jacks; and d, the
healds supported between them in the ordinary manner. To the crank shaft a,
is fixed the grooved cam or tappet plate a', for working the healds, the
peculiar shape of which keeps the shed open the requisite time for the traverse
of the shuttle, the cam a¹ acts on a bowl or friction roller projecting from the
upright bar e, which slides up and down on studs fixed to the framing; to the
upper end of the bar e is jointed the link e', the upper end of which is jointed
to the arm f, of the vibrating crank shaft f, to this shaft are cast or fixed arms
supporting the cross bar f³; to the shaft f is also fixed a toothed segment f*³
gearing into a similar segment g³ on the vibrating shaft 9, to which are cast
or fixed arms supporting the cross bar 9. To the bar f' is suspended the
grid h for holding asunder and guiding the streamer rods or catches i, the
upper ends of which are connected to the top jacks b, either by cords as shewn,
or by a stud on the piece i, fitting in a hole in the jack as shewn in Figure 4,
and the lower ends are connected to the bottom jacks c; the rods i are guided
above in the stationary grid h', and they are provided with two recesses or

page_text: catches fitting on the cross bars f and g³, and to each rod i is jointed a
swivel piece. In front of the rods i is the cross shaftj serving as a fulcrum
for the pushers or selecting fingers, which are acted upon by the pattern
chain, passing over a drum or roller k¹ on the shaft k, this shaft is turned
partly round at every revolution of the crank shaft, by the diagonal shaft 1,
which is driven below by a pair of mitre pinions and drives above the side
shaft m, on which is a bush with a pin taking into the intermittent wheel k³.
The mode of operation is as follows, and the Drawings shew the parts, in
the positions they occupy when the shed is closed. As soon as the crank has
turned its front centre, the pattern chain k³ is acted upon to bring forward a
fresh link, and the pushers j' acting on the streamer rods i, press those that
are selected for the top part of the next shed on to the vibrating bar f³, while,
those for the lower part of the shed remain on the bar 9'; consequently
during the back stroke of the lay, the cam a¹ acting on the bar e causes the
vibrating bars and g to assume the positions shewn in the detached view
Figure 3, and at the same time the jacks b and c take the positions shewn,
by dotted lines in Figure 2. During the forward stroke of the lay the parts
regain the positions shewn in Figure 2. The grid h when the shed is closed.
comes against and raises the end of the pieces 2, thereby relieving the strain
on the streamer rods or catches i, when they are being selected by the fingers
, and the studs on which the pieces ¹ swivel are made with a nib to limit the
range of the pieces >¹.
By means of the improvements above described more dwell can be given
than heretofore to the healds, and any convenient, number of healds can be
operated upon simultaneously.
Figure 5 represents a modification of our improved machinery for working
the healds; 6 is the top jack to which is jointed the streamer rod or catch i,
the lower end of which is connected to the lower jacks; the rods i are
selected and drawn up and down in the manner described in reference to the
preceding Figures.
Figure 6 represents our improved machinery applicable to index machines.
i, is a streamer rod to which is cast or fixed the stud 1, this stud supports the
swivel catch n, which is acted upon, either above or below, by the treadle or
grife forming part of the ordinary index machine, this stud is placed more
forward than heretofore customary for the purpose of preventing the backs
of the catches projecting beyond the backs of the streamer rods, which are
guided as usual between cross bars; to the streamer rods i are cast the ribs
which serve as guides to the three-armed lever hitherto employed to act on
the swivel catches n.

page_text: Figure 7 represents a modification of this part of our Invention. To the
streamer rods i are cast the cross ribs , which serve to guide the sliding
bolts, which are acted upon by the three-armed lever n', the horizontal
arm of this lever is acted upon by the pattern chain ³, or by lags with pegs.
One of the streamer rods i, may be connected to the shuttle box for bringing
the desired shuttle in line with the shuttle race.
Having thus stated the nature of our Invention and described the manner
of performing the same, we declare that we claim,—
First, the improved grooved cam or tappet plate marked a', for working the
healds of looms as described.
Secondly, the application of the vibrating cranks marked f and 9,
with the
parts acting in combination therewith, for working the healds as described.
Thirdly, jointing the streamer rods or catches to the jacks, as described.
Fourthly, the application of the pattern chain or other equivalent to the
double catches jointed to the streamer rods of index machines, as described.
Fifthly, the improved mode of constructing the streamer rods of index
machines, as shewn and described.
And, lastly, the application of sliding bolts for actuating the streamer rods
shewn and described in reference to Figure 7.
In witness whereof, we the said Charles Hartley and Thomas Hall, have
hereto set our hands and seals, this Twenty-fourth day of May, One
thousand eight hundred and sixty-five.
