of the Commissioners of Patents on the 8th January 1880.
GEORGE AMBLER, of Queensbury, in the County of York, Watchmaker.
IMPROVED PICKER TO BE EMPLOYED IN LOOMS FOR WEAVING."
"AN
This Invention relates to an improved picker having such little friction that oil
or lubricant is entirely dispensed with.
I construct my picker of metal, the bearing surface on the spindle consisting of
grooved pulleys or runners, the grooves encircling or part encircling the spindle.
The pulleys or runners are composed of hard wood or metal, and are attached to the
picker plate by studs or pins on which they revolve. Attached or cast to the picker
is a buffer plate, and a spiral spring on the spindle to ease or break the concussion;
the bottom or working portion of the picker is of metal, having attached to it the
usual sizing or buffalo hide, or the whole of the picker may be composed of buffalo
hide having the runners as above described.
Or in lieu of the runners encircling the spindle they may run in grooves or the
equivalent in the shuttle box, thus dispensing entirely with the spindle.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said George Ambler in the Great Seal Patent Office on the 8th July

page_text: great damage to the pieces whilst being woven by throwing drops of oil upon
them.
I construct my picker of metal, the bearing surface upon the spindle consisting
of grooved pulleys or runners, the grooves encircling or part encircling the spindle.
The pulleys or runners are composed preferably of hard wood or metal, and are
attached to the picker by studs or pins on which they revolve. Attached to the
picker is a buffer plate or strengthening piece; a spiral spring on the spindle behind
the buffer breaks the concussion; the working or bottom portion of the picker
carries the usual sizing or buffalo hide for receiving the picker, or the whole of the
picker may be of buffalo hide having the runners, as above described, attached
thereto.
Or the runners instead of being upon the picker may be upon the picker spindle,
and the picker slide thereon.
Or the picker may be made with runners to run in grooves in the picking box,
thus dispensing with the spindle.
Such being the nature and object of this my said Invention, in order that the
same may be fully understood I have hereunto annexed a Sheet of Drawings
illustrative thereof, and have marked the same with Figures and letters of
reference.

DESCRIPTION OF DRAWINGS.
Fig. 1 is a front elevation of my Invention shewing picker and spindle.
Fig. 2 is an end view of Fig. 1.
Figs. 3 and 4 shew a modification of picker and spindle.
Fig. 1 and 2. A is the picker constructed preferably of metal and having
runners or antifriction bowls B, B, which encircle or partly encircle the picker
spindle C. The runners B, B, are constructed preferably of hard wood or metal, and
are attached to the picker by screws, studs, or pins D, D, on which they revolve; a
spring E is placed on the spindle C to break the concussion of the picker and
buffer F G is the sizing or buffalo hide for the reception of the picker.
Figs. 3 and 4 shew a modification of the above, the runners B, B, being upon the
picker spindle C instead of upon the picker A.
Having thus fully described the nature and particulars of this my said Invention,
I would have it understood that I claim, the construction of pickers and picker
spindles having antifriction bowls or discs, as herein described and illustrated, or
any such mechanical equivalent.
In witness whereof, I, the said George Ambler, have hereunto set my hand
and seal, this Seventh day of July, in the year of our Lord One thousand
eight hundred and eighty.
GEORGE AMBLER.
