JOHN SUTCLIFFE No. 1 Gladstone Place Shettleston near Glasgow Cycle
Dealer do hereby declare the nature of this invention to be as follows:
--
Improvements in and pertaining to shuttle and picker checking mechanism of
looms to dispense with the hard stopers on check looms, in place of the usual
picker-guide mount (in a suitable bracket) a sliding carriage containing a spring
piston to receive the picker and act as picker-guide and stoper combined and
actuated by a leather strap bolted to a convenient part of the loom, in such a way
that (after the shuttle pushes the carriage back) the backward movement of the
lay tightens the strap and so pulls the carriage forward again.
Dated this 1st day of December 1893.

ICATION.
Improvements in and pertaining to Shuttle and Picker Checking
Mechanism of Looms.
JOHN SUTCLIFFE No. 1 Gladstone Place Shettleston County of Lanark N.B.
Cycle Repairer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
Improvements in and pertaining to shuttle and picker checking mechanism of
looms, to dispence with the hard stopers on checking looms. In place of the
usual picker-guide, I mount, on a suitable bracket, a sliding carriage to act as
picker-guide and stoper combined. The arrangement will be understood by
referance to the annexed drawings, the carriage A Fig. 1 is formed with a recess B
to receive the picker and it contains a spring piston C for the picker to rest against
and receive the blow of the shuttle gently, a hollow tube D is fixed into the back
part of the carriage A to receive the shank of the piston C and spiral-spring C
which holds the piston C against the picker a nut E on the end of the piston-
shank Cserves to regulate the travel of the piston, and a similar arrangement J
on the end of the hollow tube D serves to regulate the travel of the carriage A, the
bracket is provided with two fingers F Fig. 4 on which the carriage A slides
freely, G Fig. 4 shows the space between the fingers on the bracket F, the hole O
Fig. 2 in the top of the bracket admits the hollow tube D and guides it in it's
back and forward movements, the sloted bolt-hole H allows the carriage to be
adjusted to the level of the shuttle-box, the carriage is actuated by a strap, K
Fig. 3, of leather or other material, one end of which is attached to the carriage
and the other end to any convenient part of the loom. When the shuttle acts upon
the picker the latter retires along with the carriage allowing sufficient time for the
shuttle to pass up or down without interuption, and on the next return movement
of the lay the strap is drawn tight pulling the carriage forward ready for the next
return of the shuttle.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that, what I claim
as new or novel is
The general arrangement of the contrivance and in perticular the obtaining of
the parallel movement and the spring-piston in conjunction with the sliding
carriage.
