Improvements in Pickers for use in Looms for Weaving.
A communication from JOST ELMER, of Chiari, Brescia, in the Kingdom of Italy.
I, DAVID YOUNG, Patent Agent, of the firm of D. Young & Co., 11 and 12
Southampton Buildings, in the County of London, 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:—
The pickers hitherto used in looms for weaving, consist of leather bands arranged
vertically, folded upon themselves and secured by means of iron wire. The said
pickers are, moreover, provided with a single head and a single nose, in such a
manner that, when the latter is worn, the picker can no longer be used and must be
re-placed by a new picker.
The improved pickers forming the subject of this. invention are shown in the
accompanying drawings in which:-
Figures 1 and 2 show, in plan and side elevation respectively, a picker of the old
design, whilst
Figures 3, 4, 5 and 6 show, in longitudinal section and in plan respectively, two
forms of my improved picker, one with a single nose and the other with two noses.
These pickers consist of layers a of leather or other suitable material and of
rectangular form, placed one upon another and secured together by means of cement
or other adhesive material, or by means of iron wire or small nails or rivets, or in
any other suitable manner. The layers a of leather are provided with a rectangular
aperture through which the picker-staff is passed, and are very closely connected so
as to form a solid block.
The improved pickers, moreover, in place of being provided with a single head
and a single nose, are preferably provided with two heads and two noses & in such
a manner that, when one of the two noses is worn, the picker may be turned round
and used again. Further, the noses may be formed of a single piece of thick
leather, or of two or more united layers, as above described with reference to the
body of the picker.
The nose is secured to the body of the picker by means of small nails or
rivets C,
cwhich are fixed in the layers of leather and extend downward into the
upper layers forming the body of the picker.
It must be noted that, with the object of making an absolutely secure joint, the
small nail or rivet e is arranged with its head inside below the top layer of the body
of the picker, and is split at its other extremity, so that, when the nose is threaded
onto the nail, the said split end may be clinched over the leather, thus effectually
securing the nose to the body of the picker. The other small nail c¹ is only
employed to prevent the nose from turning about the rivet c.
Another feature of my improved picker consists in the strap d formed of flexible
leather (preferably white leather) which forms a part of the nose, and is prolonged
and bent down into the corresponding side of the rectangular cavity of the picker.
The object of this strap is to enable this cavity to be easily adapted to the
dimensions of the picker-staff, by cutting or paring the bottom part of one or both
of the straps d when the picker-staff cannot enter the picker..
Another improvement comprised in this invention consists in providing the heads
of the pickers with a recess e, of conical or other suitable form, to receive the point
of the shuttle so as to ensure the perfect operation of the pickers.
It is obvious that the details of construction may be somewhat modified as may
be suggested in practice, without departing from the nature of the invention.

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, as communicated to me by
my foreign correspondent, I declare that what I claim is
First. The improved picker for use in looms for weaving, made of layers of
leather arranged horizontally and secured by cement, metal rivets or nails or other
convenient means, so as to form a solid block, substantially as shown and described.
Second. The picker having two heads and two noses one at each end of the
picker, for the purpose of enabling the picker to be used a second time after the
first nose is worn out, substantially as shown and described.
Third. The herein described method of securing one or more noses to the body of
the picker, by means of a reversed nail or rivet having its head below the outer
layer or layers of leather forming the body of the picker, and its other extremity
split and clinched, substantially as shown and described.
Fourth. The picker having one or more flexible leather straps (preferably of
white leather) forming the base of the nose or noses and extending down within
the body of the picker, substantially as shown and described.
Fifth. A picker for use in looms for weaving, having a conical or other suitably
shaped recess formed in the head or in each of the heads of the picker, to receive
the point of the shuttle, for the purpose of ensuring the perfect operation of the
picker, substantially as shown and described.
Dated the 29th day of July 1893.
