Lyaips Positive MssIon--The shoot Of the
shuttle Hereafter Only a Metaphor
Description and Principle Of the New
Mr.. william Lyan has invented, patented ana put
in operation for exhibition. at the rooms OF the
Positive Motion Loom Company, Nos. 90 and 81
wooster street, a new power loom, which embodies
improvements upon the power loom as hitherto
manufactured too important 70 be dismissed with
merely passing notice. As would naturally be
gathered from the corporation name OF the company
above mentioned a company, Of which Mr.. Lyall Is
treasurer, Robert N. Woodwork being president,
has been formed with view TO the introduction OF
Mr.. Lyas invention, and already celebrated manu-
facturers Of the power ioom-as, for instance, the
Gilbert Company, the Stafford Power Loom Com
pany-have entered INTO negotiations with view TO
engraft the Improvement practically upon the manu-
facturIng interest.
That the introduction of the picker stan and
Jacquard for the acuation OF the shuttle constituted
vast improvement upon the earlier hand actuat0n
is OF course obvious; but thai so clumsy and un-
manageable system should not have been long
snc4 superseded has been puzzle to practical
weaVers. The picker stafr motion Irregular. nom
continuous and 10 an extent ungovernabe. besides
being Iranght with liability 10 dangerous accidents,
OF which the smash Is OF the least account the n.y.
ing OF the pointed shuttle being the accident most
| dreaded by the operative.
Again, the picker STAR which merely threw the
shuttle-shotit Jayelin asnlon-was unequal TO the
width; and yet again. the motion OF the shuttle hav
ing continuous relation To the action OIL the loom,
and only connecting with 1t at two points, the ope
rative had no control over IL IN the Interval from box
| To box, and hence no exact harmony OF motion be-
! tween shuttle and lay-stroKe could be esrab-
| lished IT. on the one hand, the shoot
OF the shuttle TOO impusive, 10 was thrown out
In traversng the interval; H. on the other hand TOO
laX the beat Of the lay liable to push 1t through
! the warp laerally at the expense OF an annoying
smash. 10 eirect a continuous and goyernabe reia
! tlon between me two, has for long time been

power loom; ana. MIR. Lyai having been the first 10
| solve ii practically, TO that gentleman must be
awarded the honor Of having produced an invention
| destined 10 work a revolution In manufacturing.
| The most noticeable feature in MIR. I.yai's loom
and one To take the eye Of the practical operative
soonest-is the absence OF the picker siaff and its
interminabie ciatter; also the easy continuous and
regular actuanon Of the shuttle, which Is carried
| tro of the motive power and IN harmony with
the action Of the lay thus removing the liability to
| smash. Hence the loom can be stopped at any
time and at any point thefactuatioa Of the shuttle
across the interval and set IN from any point
without the least danger Of arrangement This ad-
vantage, the eye Of the practical manufacturer.
Is OF its greatest unless We except the fur
ther advantage that the njst inexperienced hand or
operative can operate II about as well as the most
experienced.
| One point more than all Others merits mention.
The scope OF the shuttle is practically unlimited, so
| that fabric twenty yards In width can be woven
Just as easily as fabric Of the ordinary width
| What desideratum this might become In carpet
weaving can only be estimated the shuttle carryrngits
weft any assignable distance from foot to y feet
with the same case and precision OF action. Again
the actuatlon OF the shuttle being continuous, the
| wet Is subjected TO no sudden pulling and stran
| aud thread OF the most delicate texture can be
filed In without the slightest liability to breakage
| Again. the reed moves put little distance, causing
very little 10 the warp III weaving. Again, the
heddles need TO he opened less than n looms OF tue
Old pattern, and hence that severity OF strain to the
warp which pertains TO the Ordinary power loom Is
obvlated and avoided Again, the simplicity OF the
| motion enables the manufacturer 10 dispense with
skilled labor to great extent, and, for The 1rst
time, affords American manufacturers prospect OF
| competing with the skilled labor OF European
centres the manufacture OF delicate silk faDrlcs,
| and, In TACT, delicate fabrics OF all sorts.
All these are very practical advantages While the
| utility OF power IN running the loom constitutes
another advantage not to be forgotten IN the EMU
| meratlon. In operating the common power loom
| certain speed must always be observed and little
variation speed can be tolerated Abate the speed
| and the actuaLiOn OF the shuttle is imperfect from
| want OF impulse Increase II beyond gwen average
and the shuttle nies out; and both these difficulties
direct results OF the fact that the shuttle is shot
by impulse not moved s Sy regular ana continuous
removes this difficulty. in the operation OF
the power loom, and is operated with less

Stroke predecessor. one more advantage re-
| mains to be noted. The beat OF the lay is not

to come to rest. resulting IN finer drawing OF the
! thread and the desderatum OF perfect seyaye;
and thus. Ia TOTO at single coup, the imperfect sell
wage may be cast out Of the category OF difficulties
! In manufacturing. The adjustment OIL weft to warp
is perfected before the beat or the lay takes place
The ingenuity by which this great deslderatum to

the shuttle at all points with the motion Of the loom
