New or Improved Apparatus to be used in Japanning the Ribs and
Stretchers of Umbrellas and Parasols.
We WILLIAM ALLEN BINDLEY and WILLIAM JAMES GELL both of
Armstrong Works Chester Street Aston Road Birmingham in the County of
Warwick Manufacturers and AMBROSE FREDERICK BOHAM of Sutton Street
Aston near Birmingham aforesaid Machinist do hereby declare the nature of this
invention to be as follows:-
In the ordinary method of japanning ribs and stretchers they are dipped into a
bath or pan of japan and after removal from the bath they are deprived of the
superfluous japan by first draining them and afterwards giving them sharp blows.
They are then stoved.
By the use of the apparatus constituting our invention the removal of the
superfluous japan is readily effected and the thickness of the japan coating
regulated at pleasure.
Our new or improved apparatus is constructed and used in the following manner.
We mount upon a shaft capable of rapid rotary motion in bearings four or other
number of boxes or receptacles of a size and shape suitable to contain the ribs or
stretchers to be treated. These boxes or receptacles are arranged on the shaft in
the direction of radii and when four are used each box is at right angles to the
adjacent one. The outer ends of the boxes or receptacles or those ends most
distant from the shaft are provided with perforated lids or covers by which the ribs
or stretchers are enclosed in the boxes and by the removal of the said lids or covers
the contents of the boxes can be withdrawn. The rotary shaft carrying the radial
boxes or receptacles may either be vertical or horizontal. In the former case the
boxes rotate in a horizontal plane and in the latter case in a vertical plane. By
means of a driving pulley and band a rapid rotary motion may be given to the
shaft and its radial boxes or receptacles. The ribs or stretchers having been
dipped in the bath or pan of japan are removed therefrom and placed in the radial
boxes at their open ends and the said ends closed by their perforated lids or covers.
The shaft and boxes being set in rapid motion the superfluous japan is by
centrifugal force rapidly removed from them the japan thrown off passing in part
through the perforations in the lids or covers. By varying the speed of the shaft
the thickness of the coating of japan upon the ribs or stretchers can be regulated.
The japan coated ribs or stretchers thus treated are finished by stoving in the
usual way.
We do not limit ourselves to any particular construction of the boxes or
receptacles in which the japan coated ribs or stretchers to be operated upon are
contained nor to the particular way of securing them to the rotating shaft as the
essence of our invention consists in removing the superfluous japan coating from
and regulating the thickness of the said coating on the ribs or stretchers by
centrifugal force effected substantially as herein before described.

New or Improved Apparatus to be used in Japanning the Ribs and
Stretchers of Umbrellas and Parasols:
We WILLIAM ALLEN BINDLEY and WILLIAM JAMES GELL both of
Armstrong Works, Chester Street, Aston Road Birmingham in the County of
Warwick Manufacturers and AMBROSE FREDERICK BOHAM of Sutton Street,
Aston near Birmingham aforesaid Machinist do hereby declare the nature of our
invention and in what manner the same is to be performed to be particularly
described and' ascertained in and by the following statement :-
In the ordinary method of japanning ribs and stretchers they are dipped into a
bath or pan of japan and after removal from the bath they are deprived of the
superfluous japan by first draining them and afterwards giving them sharp blows.
They are then stoved.
By the use of the apparatus constituting our invention the removal of the
superfluous japan is readily effected and the thickness of the japan coating
regulated at pleasure.
Our new or improved apparatus is constructed and used in the following manner.
We mount upon a shaft capable of rapid rotary motion in bearings, four or other
number of boxes or receptacles of a size and shape suitable to contain the ribs or
stretchers to be treated. These boxes or receptacles are arranged on the shaft in
the direction of radii and when four are used each box is at right angles to the
adjacent one. The outer ends of the boxes or receptacles or those ends most
distant from the shaft are provided with perforated lids or covers by which the ribs
or stretchers are enclosed in the boxes and by the removal of the said lids or
covers the contents of the boxes can be withdrawn. The rotary shaft carrying
the radial boxes or receptacles may either be vertical or horizontal or in an
intermediate position: In the former case the boxes rotate in a horizontal plane
and in the latter case either in a vertical or inclined plane. By means of a driving
pulley and band a rapid rotary motion may be given to the shaft and its radial
boxes or receptacles:
The ribs or stretchers having been dipped in the bath or pan of japan arc
removed therefrom and placed in the radial boxes at their open ends and the said
ends closed by their perforated lids or covers. The shaft and boxes being set in
rapid motion the superfluous japan is by centrifugal force rapidly removed from
them the japan thrown off passing through the perforations in the lids or covers.
We do not limit ourselves to any particular construction of the boxes or
receptacles in which the japan coated ribs or stretchers to be operated upon are
contained nor to the particular way of securing them to the rotating shaft as the
essence of our invention consists in removing the superfluous japan coating from and
regulating the thickness of the said coating on the ribs or stretchers by centrifugal
force effected substantially as hereinbefore described.
We will now proceed to describe with reference to the accompanying drawings
the manner in which our invention is to be performed.
Figure represents in side elevation and Figure 2 in end elevation apparatus
constructed according to our invention to be used for removing the superfluous
japan from and regulating the thickness of the japan coating on the ribs and
stretchers of umbrellas and parasols; Figure represents in vertical section
partly in front elevation and Figure 4 in plan partly in horizontal section the
radial boxes or receptacles of the apparatus drawn to a larger scale detached from
their rotating shaft.
The same letters of reference indicate the same parts in the several figures of
the drawings.
a is the rotating shaft of the apparatus supported in the bearings b, b carried by
the frame c; ef are the fast and loose pulleys for rapidly driving the said rotating
shaft by means of a band as usual; gy are the radial boxes or receptacles in which

page_text: the ribs or stretchers are placed after they have been japanned the said boxes or
receptacles being connected to the bush h (see Figure 3) which is keyed to the
rotating shaft a. We have represented an apparatus provided with four radial
boxes or receptacles each box being at right angles to the adjacent one but more
than four boxes or receptacles may be combined in the apparatus; and instead of
the boxes moving in a vertical plane they may be mounted on a vertical or inclined
shaft and move in a horizontal or inclined plane. We prefer however to employ
four boxes or receptacles moving in a vertical plane as represented. The outer
open end of each of the boxes or receptacles g, g is provided with a perforated lid
or cover i by the removal of which the contents of the box or receptacle can be
withdrawn. Each lid or cover i is fixed in its place by means of the pair of side
screw bolts k, kpassing through the snugs I, 1 on the box and fixed by the screw
nuts represented screwed on the said screw bolts and made to bear against the
inner ends of the said snugs as best seen in the enlarged views Figures 3 and 4.
Surrounding the radial boxes or receptacles y 9, 9, 9 is a guard upon the interior
of which the japan thrown off the ribs or stretchers and passing through the
perforations in the lids or covers i, i is received and by which guard it is conducted
in part to a receiver at the base of the apparatus. A guard of the kind
represented in Figure 1 and partly removed in Figure 2 may be used. It consists
of the fixed bottom half m connected to the receiver n and the upper half made in
two parts marked p, q jointed to the lower half so that the upper jointed parts p, 4
can be turned outwards or backwards for filling the boxes with or removing the
japan coated articles from them.
The meeting ends of the jointed upper parts of the guard are secured together
by bolts, clips or otherwise.
We prefer to make each of the radial boxes or receptacles of about three feet
long and about nine inches in diameter so that each box or receptacle will hold say
about four gross of ribs or stretchers but we do not limit ourselves to making the
boxes or receptacles of any particular size and we prefer to drive the rotating
boxes so that they make about 300 revolutions per minute.
The lids or covers ii having been removed from the ends of the boxes or
receptacles 99 and the driving band being placed on the loose pulley of the driving
shaft, the apparatus is ready to receive the japan coated ribs or stretchers which
are placed in the boxes or receptacles through their open or uncovered ends. The
ends of the boxes having been covered by the perforated covers i, i the driving band
is passed onto the fast driving pulley and a rapid rotatory motion thereby given to
the shaft. and boxes and the superfluous japan is by centrifugal force rapidly
reinoved from the ribs or stretchers the japan thrown off them passing through the
perforations in the lids or covers ii and being received on the guard m, p, . By
varying the speed of the shaft a the thickness of the coating of japan upon the ribs
or stretchers can be regulated. The japan coated ribs or stretchers thus treated
are finished by stoving in the usual way.
Having now particularly described and ascertained the nature of our inven-
tion and the manner in which the same is to be performed we declare that we
claim as our invention:-
The new or improved apparatus herein before described and illustrated in the
accompanying drawing to be used in removing by centrifugal force the superfluous
japan coating from and regulating the thickness of the said coating on the ribs
and stretchers of umbrellas and parasols, the parts of the said apparatus being
constructed arranged and worked substantially as described and illustrated.
