Improvements in Spring Retainers for the Runners of Umbrellas
and Parasols.
I JOHN ROSE of 1703 Chadwick Street Umbrella Manufacturer of Philadelphia
State of Pennsylvania in the United States of America 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:—
The object of this Invention is to so construct a retainer for the runners of
Umbrellas or parasols that the same will be of an inexpensive character and will not
necessitate any expensive preparation of the stick for its reception. This object is
attained in the manner hereinafter set forth reference being had to the accompanying
drawing in which:
Figure 1 is an enlarged perspective view of the improved retainer detached from
the stick.
Figure 2 is an enlarged longitudinal section of part of an umbrella stick with the
improved runner retainer applied thereto.
Figure 3 is a transverse section on the line 1-2 Figure 2 and
Figure 4 is a transverse section on the line 3-4 Figure 2.
A is the stick of the umbrella or parasol in one side of which is formed a slot or mortice.c
for the reception of the retainer the latter consisting of a skeleton frame comprising a
back bar a and a front bar severed so as to form two projecting tongues band d the
whole being made in one piece. The back bar a of the retainer is partly straight and
partly segmental the segmental ends fitting snugly to the base of the slot or mortice a
in the stick and is provided with a lug projecting from the back bar and serving as
the means whereby the retainer is held in place in the stick. The tongues and d of
the front bar of the retainer are flush with the face of the stick but the tongue b has
an enlargement i which serves as the stop for the runner, the said tongue being elastic
and the enlargement being bevelled on one face so that as the runner is moved past
or over the same the tongue will be forced into the recess in the stick and will spring

page_text: outward therefrom when the pressure is removed the end of the tongue d overlapping
the end of the tongue so as to limit its outward movement as indicated in figure 2.
As the spring tongue in itself receives but little lateral support from the stick and
in order to obviate twisting or distortion of the said tongue when lateral pressure is
accidentally exerted upon the projecting portion the free end of the tongue is
provided with an inwardly projecting lug or wing g which materially increases the
lateral bearing of the tongue against the sides of the slot or mortise cut in the stick
for the reception of the retainer and thereby enables the tongue to resist any tendency
to distortion which might arise from lateral pressure upon the projection i (see
Figure 3).
For securing the improved retainer in the stick the projecting lug of the back
bar a is provided with one or more laterally projecting spurs or barbs m which may be
struck up from the metal of the lug, two of these spurs or barbs being shown in the
present instance one projecting laterally from one side of the lug and the other from
the opposite side of the same (see Figure 4).
When the retainer is pressed into the slot or mortise in the stick these spurs or
barbs are pressed inwards but as the metal of which the retainer is made possesses a
cortain amount of resiliency said spurs or barbs have a constant tendency to spring
outward and engage with the stick on opposite sides of the slot or mortiso therein so
as to effectually prevent the accidental loosening or detaching of the retainer from the
stick.
By this means the application of the retainer is simplified and cheapened as said
retainer is simply pressed into the slot or mortise in the stick no drilling or perforation
of the stick and no transverse retaining pin being necessary.
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. An umbrella runner retainer comprising a back bar and a front bar the latter
having two projecting tongues one forming a stop tongue and the other forming a
spring tongue and having an outwardly projecting retaining lug and an inwardly
projecting wing for preventing twisting or lateral distortion of the tongue all
substantially as herein before described with reference to the accompanying drawing.
2. The combination of the stick having a slot or mortise therein with the retainer
fitting into the said slot or mortise and consisting of a back bar and a front bar the
latter having two projecting tongues one forming a stop tongue and the other forming
a spring tongue provided with an outwardly projecting retaining lug and with an
inwardly projecting ring bearing against the sides of the slot in the stick and thereby
serving to prevent lateral deflection of the retaining lug all substantially as hereinbefore
described with reference to the accompanying drawings.
3. The combination of the stick having a slot or mortise therein with a retainer
having a front bar forming an elastic tongue and a back bar provided with one or more
laterally projecting elastic spurs or barbs for engaging with the stick and preventing
removal of the retainer therefrom all substantially as hereinbefore described and
illustrated in the accompanying drawings.
4. The combination of the stick having a slot or mortise therein the retainer
adapted thereto and having a front bar forming an elastic tongue and a back bar
having clastic spurs or barbs projecting from opposite sides of the same and engaging
with the stick to prevent removal of the retainer therefrom all substantially as
herein before described with reference to the accompanying drawings.
