PROVISIONAL SPECIFICATION.
An Improved Fastening for Carriage Blinds.
I, WILLIAM WILSON HORN, of the Firm of Horn & Son of 151 Strand, in the
County of Middlesex, Patent Agent, do hereby declare the nature of this invention
(a communication to me from Alpha Buker of Hueneme in the State of California,
United States of America, Inventor,) to be as follows:-
This invention relates to an improved fastening for carriage blinds, and has for
its object the production of a cheap, simple and highly efficient device of this
character which is capable of being readily and easily operated.
The invention consists of a stationary plate having a circular hole or opening
formed therethrough, the said plate being secured at a suitable position to the
blind. The said hole is intended. for the passage of the stud or button by which
the blind is secured when drawn down.
Upon the front of the plate before mentioned, in, suitable guides thereon, is
mounted a spring latch adapted to lock the stud after passing through the hole in
the said plate. The said spring latch is adapted to be released by a suitable
finger-hole from the stud so as to allow the passage of the latter through the said
opening either in securing or releasing the blind.

COMPLETE SPECIFICATION.
An Improved Fastening for Carriage Blinds.
I WILLIAM WILSON HORN of the Firm of Horn & Son 151, Strand in the
County of Middlesex Patent Agent do hereby declare the nature of this invention
(a communication to me from Alpha Buker of Huenene State of California
United States of America Inventor) and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to a new and improved carriage blind fastener and has for
its object the production of a cheap simple and highly efficient device of this
character which is capable of being readily and easily operated.
The invention consists of a plate having a circular hole or opening and a spring
pressed slide movable in guideways of said plate and having a cylindrical portion for
the spring one end of which bears against or is secured to the inner end of said
cylindrical portion while its other end is constantly in engagement with a lug or
stop fast with said plate substantially as hereinafter fully set forth, and particularly
pointed out in the claim.
In the accompanying drawings
Fig. 1 is a view in front elevation, shewing my improved fastener attached to a
carriage blind;
Fig. 2 is a vertical longitudinal sectional view on the line x, x, Fig. 1 ;
Fig. 3 is a transverse sectional view on the line y, y, Fig. 1 ;
Fig. 4 is a detail hereinafter described.
Figs. 2 and 3 are both drawn to an enlarged scale.
Referring to the drawings, A represents a carriage blind, and a a plate rigidly
hola A onaning a¹ having an elongated

page_text: the front of this plate a is rivetted or otherwise fixed a plate c, the shape of which
is clearly shewn in Fig. 4, the said plate c having a long slot band parallel
guideways 6 formed therein.
B is a movable member or lock, which consists of a plate 62 having side flanges b
designed to fit into the guideways and a central longitudinal cylindrical
chamber. From the outer portion of this chamber projects a lug or finger
rest 65.
The extremity or inner end of this member has a notch or recess
therein bº.
Within the cylindrical chamber 6 is a coil spring C the inner end of which
bears against the inner end of said cylindrical chamber, it being held therein by a
bridge or cross plate. The outer end of this spring is constantly in engagement
with a lug or stud D rigidly secured to plate a. The shape of this stud or lug
conforms to the cylindrical chamber and permits the movable member to be
moved freely by the operator. When the movable member is in its normal
position, namely, at the inner limit of its movement,-the notch in the inner end
of said member will be coincident with the elongated portion of hole or opening a',
and form a perfect fit for the shank of holding-button E.
From what has been said it will be seen that by forcing the movable member
against the action of its spring clearance will be had of the central circular hole or
opening, and then the headed portion of the holding-button can be passed there-
through either in securing or releasing the blind.
I am aware that it is not new to provide a carriage blind fastener with a spring
arm which will engage the shark of a securing button when the latter is projected
through an opening in the blind, and hence my invention is not designed to cover
such construction.
A fastener constructed as herein described is extremely simple and inexpensive,
and all danger of accidental loosening or disengagement from the holding button is
avoided.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is,
The herein described improved carriage blind fastener, consisting of the stationary
plate having a hole or opening and a slot and parallel guideways, the movable
member having flanged ends fitting in said guideways, and having a longitudinal
cylindrical chamber fitting said slot, the bridge near. the inner end of said
cylindrical chamber, the lug or stop secured to said stationary plate and projecting
into said cylindrical chamber, and the coil spring bearing at its inner end against
the inner end of said cylindrical chamber, and at its outer end against said lng or
stop, substantially as set forth and illustrated.
