Improvements in Loom Picking-stick Tappets for Weaving.
We, BENJAMIN BERRY of 128 College Road, Bradford, in the county of York,
mechanical draughtsman, and DANIEL BATEMAN BRIGGS, Ludlam Street Bradford
in the county of York, commission wool comber, do hereby declare the nature of this
invention to be as follows:-
This our invention has reference and consists of an improvement in looms for
weaving, and our invention consists of an improvement in the male clutch tappet
or shuttle picking stick tappet, used in looms for weaving. This invention or improve-
ment consists of an automatic or self lubrication of steel runner or bowl, attached
to, the male shuttle tappet being made or cast with hollow chamber cored out for the
or bowl,
reception or containing of a quantity of oil to supply the steel runner
allowing of a constant drop to be thrown on at every revolution of tappet on to the
outward surface of steel runner or bowl, when at its lowest or downward position,
and issuing from the supply of oil contained in the hollow chamber of tappet, through
a small aperture or hole drilled in tappet casting immediately over the steel runner
or bowl. This said tappet has provided to it for the admission of air a small automatic
air, valve, combined with the feed oil cup to hollow chamber, and fastened or screwed

COMPLETE SPECIFICATION.
Improvements in Loom Picking-stick Tappets for Weaving.
We BENJAMIN BERRY of 128 College Road Bradford in the county of York
Mechanical Draughtsman and DANIEL BATEMAN BRIGGS, Ludlam Street Bradford
in the county of York, commission wool comber, 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:-
Our invention consists of an improvement in the male clutch tappet or shuttle
picking stick tappets known as the Crompton and other similar types of weaving
looms, and its object is to facilitate or automatically self lubricate the steel anti-
friction runner, bowl or roller attached to this class of tappet and carried around
with it.
The said improvements consists in casting the said tappet with hollow chamber
cored out, in the manner hereafter described and so forming a chamber for the
reception of oil as lubricant which is automatically supplied to lubricate said anti-
friction roller.
In the accompanying drawings-Figure 1 represents a longitudinal section through
the center of the tappet and Figure 2 is a side view of the same.
The tappet A is cored out when cast so as to form the chamber B and a hole is
truly bored to tightly fit the central boss C. of the tappet and such tappet is
An air-valve E
shrunk thereon or a tight joint made in any convenient manner.
is fitted in the opposite end of tappet to that carrying the anti-friction roller or
bowl F and such valve also forms the orifice by which the chamber B is filled with
oil or lubricant. A fine hole or educt G drilled through the tappet immediately over
the steel roller or bowl communicating with the hollow chamber B and allows the
passage of a minute supply or lubricant to drop on to the steel roller or bowl F when
it reaches its lowest point in each revolution, the air valve dropping open to allow the

page_text: oil or lubricant to flow freely as the tappet revolves and when the air valve E
passes to lower side, it closes by its own weight and prevents the oil or lubricant from
escaping.
Having now fully described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what we
claim is:
1. A Tappet for weaving looms provided with an oil or lubricating hollow chamber
having a duct leading to the anti-friction roller or bowl carried by the said tappet
adapted to supply the said steel roller or bowl with oil or lubricant substantially as
herein shown and described.
2. The combination with a tappet provided with an oil or lubricating chamber
and an educt of air-valve arranged for the passage of air substantially as herein
shown and described and for the purpose specified.
In witness whereof this Thirtieth day of January in the year of our Lord One
thousand eight hundred and ninety
