PROVISIONAL SPECIFICATION.
An Improvement in Umbrella Runners.
We THOMAS ALDIN CRABTREE of East Surrey, Hancock County, Toacher, and
BENJAMIN MORRILL of Blue Hill, Hancock County both in the State of Maine, in the
United States of America, Druggist and Apothecary do hereby declare the nature of
this invention to be as follows:-
Our Invention relates to umbrella runners, and it consists of a tubular runner
having a bayonet slot at the upper and lower ends for engagement with studs at the
upper and lower part of the umbrella stick in order to hold the umbrella in the open
and closed positions respectively. The runner notch is carried by an outer tube or
sleeve connected with the runner by a stud and slot which permits of the runner being
partially rotated independently of the outer sleeve and notch for the purpose of
engaging and disengaging the bayonet fastenings. The bayonet slots of the runner
have Haring mouths to facilitate their engagement with the pins of the stick, and the
runner has a milled ring upon its lower end to enable it to be easily turned.
Dated this 28th day of December 1886.

We, THOMAS ALDIN CRABTREE (Teacher) of East Surry and BENJAMIN MORRILL
(Druggist and Apothecary) of Blue Hill, both in the County of Hancock and State
of Maine, 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 :-
Our Invention relates to umbrella runners; and it consists of a tubular runner
having a bayonet slot at the upper and lower end for engagement with studs at the
upper and lower parts of the umbrella stick in combination with an outer tube or
sleeve carrying the runner notch and connected with the runner by a stud and slot
which permits of the runner being partially rotated independently of the sleeve, for
the purpose of engaging and disengaging the bayonet fastenings, all as hereinafter
more fully described.
Reference is to be had to the accompanying drawings forming part of this
specification, in which figure 1 is a perspective view of an umbrella frame. Figure 2
is a similar view on a larger scale, shewing the runner in the position it occupies
when the umbrella is closed, and figure 3 is a perspective view of the runner removed
from the stick. Similar letters of reference indicate corresponding parts in all the
figures.
In the accompanying drawings, A is the umbrella stick which may be of any
suitable material, and which has two studs B and C respectively at the upper and
lower portions of the stick. Sliding upon the stick between the studs B and C, is a
runner D, the ends of which are provided with bayonet slots EE each having a
flaring mouth or opening as shown. At the lower end of the runner is a milled ring G
to enable the runner to be easily turned on the stick for the purpose of engaging or
disengaging the bayonet fastenings. An outer sleeve H is secured upon the runner,
by means of a pin L near the lower end of the runner which projects through a
slot K near the lower end of the outer sleeve, said slot being shorter than the mouth
or outer portion of the bayonet slots E. To the upper end of the sleeve H is secured
an ordinary notch M to which the stretchers are jointed in the usual way, the ribs
being jointed to the ordinary top notch. The notch M is provented by the stretchers
from turning with the runner, but the runner D can be readily turned upon the stick
within the limits of the slct K, the sleeve H affording as long a brace or stay for the
notch M as is found in the runners used upon ordinary umbrellas.
When it is desired to raise tho umbrella, the runner D is turned upon the stick
until the bayonet slot E is disengaged from the pin C it is then pushed up the stick
until the pin B enters the upper bayonet slot E which by a slight turn of the runner,
is caused to engage with the pin B so as to prevent the runner from sliding down the
stick. To close the umbrella, the above operation is reversed.

page_text: Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed; we would have it understood that
previous to our invention, umbrellas have been made with a shallow groove or channel
around them in which a sleeve having the notch-piece around it has been secured, but
this method is objectionable, as the only support for the entire weight of the top, is the
lower side of the shallow groove which would soon wear sufficiently to permit the
sleeve to slip down over the runner. Another objection to it, is the difficulty of
fitting the sleeve in such a groove. Hence, we do not wish to claim such construction
but what we claim is ;-
The combination with a runner for umbrellas having a bayonet slot with outwardly
flaring mouth at each end, of a pin projecting from its intermediate portion and a
milled ring around its lower portion, and an outer sleeve around said runner having
a notch around its upper portion and a slot near its lower portion.
