page_text: I JOHN WEEKS of 19 Gospel Oak Grove, Haverstock Hill, in the County of
Middlesex Umbrella Maker 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:-
In working out the invention for which I on the 4th November 1886 applied for
Letters Patent No. 14228 I have arrived at certain results some of which do not
appear to be comprised within the Provisional Specification of such application, and
my present invention comprises such results. I have found that the combination of
a Tor double trough shaped stretcher with a trough shaped rib in such a manner that
these fit into one another when the umbrella is closed, presents manifold advantages,
which can be attained by various modifications of the rib and stretcher joints and
as hereinafter described. I provide also that the git or joint piece shall be of such a
form as to avoid abrasion of the umbrella stick when the umbrella is closed. I provide
also for strengthening the rib near the stretcher joint by forming a small bulge upon
the rib at that point. I also provide a solid three forked prong upon the end of the
double trough shaped stretcher by means of which it can be connected to the rib.
Some of my improvements can be used separately or in combination under different
circumstances, as hereinafter appears.
In the annexed sheet of drawings Figures 1 to 18 inclusive show various modifica-
tions of my improvements. In these figures A represents the trough_shaped rib,
B the Tor double trough shaped stretcher and C the git or joint piece. Figures 4, 5
With the sections
and 6 show sections of forms of stretcher which may be used.
shown in Figures 4 and 6 I am enabled to obtain a solid three pronged fork at the
end of the stretcher for the attachment of the stretcher to the rib. Hitherto where a
single trough shaped stretcher has been used, a middle bit has been soldered or other-
wise secured into the trough in order to get a three pronged fork. But a solid three
pronged fork fashioned out of one piece of metal has never before been used. One
form of such fork is clearly shown in plan view in Figure 9 and in side view and end
view respectively in Figures 8 and 10.
Figures 1, 2, 3 and 4 show an arrangement in which a T or double trough shaped
stretcher is combined with a trough shaped rib. The stretcher B is first by a rivet
D

page_text: jointed to the git C which consists of a piece of sheet metal and the joint piece or git
is then lapped or folded round the rib, so that the joint lies within the trough. The
rib A and stretcher B fit into one another as shown in Figure so that the frame is
very compact when closed. The rib A is in this case not pierced by any hole for the
rivet for the joint of rib and stretcher. Figures 7, 8, 9, 10 and 11 show another
arrangement in which a double trough shaped stretcher is combined with a trough
shaped rib.
In this case the fork joint has three prongs formed out of the stretcher and in one
piece therewith. In this arrangement the hole for the pin or rivet is pierced through
both the git and the rib.
Figures 12, 13, 14 and 15 show a similar arrangement in which the hole for the
joint pin or rivet does not pass through the rib but only through the projecting folded
portion of the git C.
In both the preceding arrangements that is to say Figures 7 to 11 and Figures 12
to 15 it will be seen that the git C differs from the ordinary git in being tapered off
to the line of the rib towards the point of the umbrella, so that abrasion of the stick
by a projecting corner of the git when the umbrella is closed is avoided.
Figures 16, 17 and 18 show the method of strengthening the rib which I sometimes
adopt when the hole for the pin is pierced through the substance of the rib. I pro-
duce by suitable tools a bulge in the rib so that the width of the margin of metal
around the hole is increased and the rib is rendered less liable to fracture at the point
where the rib is pierced by the hole for the rivet. The git may be secured in position
as shown in Figures 17 and 18. The git is by preference cut out as shown at c in
Figures 17 and 18 in order to save needless increase in bulk at this place.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is
1. In umbrella frames, the combination of a trough shaped rib with a T shaped or
double trough shaped stretcher substantially as hereinbefore described.
2. In umbrella frames, the combination of the rib and stretcher connected by means
of a git or joint piece tapered in the manner and for the purpose hereinbefore
described.
3. An umbrella stretcher having a three pronged fork for connecting the stretcher
to the rib fashioned out of one piece of metal with the stretcher substantially as
hereinbefore described.
4. An umbrella rib of trough shaped form having a bulge upon it as described in
order to strengthen the rib at the place where it is pierced for the pin of the stretcher
joint.
5. The combination of git with umbrella rib of trough shaped form strengthened by
means of a bulge as shown in Figures 17 and 18.
6. The combination of rib and stretcher hereinbefore described and illustrated in
Figures 1, 2, 3, 4, 5 and 6.
7. The combination of rib and stretcher herein before described and illustrated in
Figures 6, 7, 8, 9, 10 and 11.
8. The combination of rib and stretcher hereinbefore described and illustrated in
Figures 6, 12, 13, 14 and 15.
Dated this 16th day of April 1887.
