WILLIAM HENRY WILLIAMS, of Birmingham, in the County of Warwick, Manu-
facturer. “IMPROVEMENTS IN AND MACHINERY FOR ORNAMENTING WOODEN GAS
BLOCKS OR PATERASES, SHADE STANDS, BREAD TRAYS, AND OTHER LIKE WOODEN
ARTICLES."
My Invention consists in ornamenting the articles enumerated, and other like
wooden articles, by an impressing process effected by the action of a stamp or other
like machine as herein-after described, and further, of the construction and arrange-
ments of the parts of the machinery herein-after described to be used in ornamenting
the said articles by the said impressing process.
In ornamenting according to my Invention, say, the border or marginal parts of
a wooden gas block or pateras, I take a die, the acting face of which is engraved
with the counterpart of the ornamental design to be impressed upon the block, and
I fix the said die in a bolt or slide of a stamp or other like machine, the said dic
having such a size and figure as will ornament only a portion, say one-eighth or one-
sixth, of the border or margin of the gas block or pateras at each blow.
The wooden block to be ornamented is so stationed on a carrying plate or table that
a portion only of the border or margin of the block is situated under the ornamented
die in the bolt or slide. By the descent of the die that portion of the gas block
under it is impressed by the said die, and by giving an intermittent motion to the
carrying plate or table supporting the block, the different parts of the border or
margin of the block are in turn brought under the operation of the die. In this
way, the whole of the border is ornamented by a series of blows given by the die in
conjunction with a series of movements given to the plate or table carrying the
block, the ornamental border consisting of a repetition of the pattern engraved on
the die.
Bread trays, shade stands, and other wooden articles having generally a flat
symmetrical figure may be ornamented in the manner described.
The machinery constituting part of my Invention, which I prefer to use in conduct-
ing the impressing process, is constructed and worked essentially as follows:-I work
the bolt or slide to which the ornamental die is fixed by means of a cam or eccentric
carried by the main shaft of the machine, the said cam or eccentric acting upon the
strap or rod which is connected by links to the said bolt or slide. The said bolt or
Daina 2.71

page_text: slide works in a guide on the framing or uprights of the machine, and by the action
of the said cam or eccentric the bolt or slide is forcibly brought down and the die
carried by it made to impress the article beneath it.
I support the wooden gas block or pateras, or other article to be ornamented, on
a horizontal table working on the bed of the machine, and having an intermittent
rotatory motion given to it. The axis of the said table is situated excentrically to
the axis of the bolt or slide so that a portion only of the circumference or margin of
the table is situated under the said bolt or slide. The axis of the table projects
above its upper side and constitutes an angular peg on which a hole in the middle of
the block or article fits. The block or article is thus fixed concentrically on the
table during the ornamenting process. The intermittent motion of the table carry-
ing the block or article to be ornamented is affected by means of a ratchet wheel on
the axis of the said table, with which ratchet wheel a pawl engages, the pawl lever
having a reciprocating motion given to it by a connecting rod worked from the cam
or eccentric shaft of the machine.
The sliding motion of the bolt of slide, to which the impressing die is fixed, and
the intermittent motion of the table carrying the block or article, are so arranged
that when the bolt is about to descend_the table is stationary, the said table being
moved through the required angle so as to bring a fresh portion of the article under
the die during the ascending motion of the said die.
For the purpose of rapidly fixing and removing the articles operated upon, the
axis of the intermittent rotatory table is fixed to a slide worked by hand and drawn
out after the ornamenting of one article has been effected, for the removal of the
ornamented article and the substitution of another to be ornamented..
The blocks or wooden articles to be ornamented are made by preference by the
turning process as usual, the block or article being so cut from the wood of which it
is made that the fibres shall be presented endwise to the surface to be ornamental.
