Improvements in Spring Retainers for the Runners of Umbrellas
and Parasols.
We JOHN ROSE of 1703 Chadwick Street in the City of Philadelphia State of
Pennsylvania United States of America Umbrella Manufacturer and CHARLES
FRANKLIN DOLLNER of 1417 North Thirteenth Street in said City of Philadelphia
Umbrella Stick Manufacturer 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 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 b
and 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 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 has an enlargement which serves as the stop for the runner the said
tongue being elastic and the enlargement i 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 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.

page_text: As the spring tongue 6 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 mortice 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 shewn 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 mortice in the stick these spurs or
barbs are pressed inwards but as the metal of which the retainer is made possesses a
certain 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 mortice 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 mortice 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 the said Inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
First. 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 hereinbefore described with reference to the accompanying drawing.
Second. The combination of the stick having a slot or mortice therein with the
retainer fitting into the said slot or mortice and consisting of a back bar and a front
bar the latter having two projecting tongues one formning a stop tongue and the other
forming a spring tongue provided with an outwardly projecting retaining lug and
with an inwardly projecting wing 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.
Third. The combination of the stick having a slot or mortice therein with a retainer
having a front bar forming an elastic tongue and a back bar provided with one or
more laterally projecting clastic spurs or barbs for engaging with the stick and
preventing removal of the retainer therefrom all substantially as herein before described
and illustrated in the accompanying drawings.
Fourth. The combination of the stick having a slot or mortice therein the retainer
adapted thereto and having a front bar forming an elastic tongue and a back bar
having elastic 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.
