COMPLETE SPECIFICATION.
Improvements in Bag Fasteners.
:
1, Louis A. WALKER, of 323 Bedford Avenue Brooklyn, in the County of
Kings, State of New York, United States of America, Gentleman, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
This invention relates to certain new and useful improvements in bag fasteners,
and it has for its objects among others, to provide an improved fastener which when
the bag is closed will clasp over the mouth of the same, and not only close it but
cover it. I provide a part to work within the bag, and another part to operate
outside the bag, between the two the mouth of the bag when drawn together by the
string is held. The device permits of various modifications in details of construction.
That shown is what at the present time is considered the most desirable and
efficient.
Other objects and advantages of the invention will hereinafter appear and the
novel features thereof will be specifically defined by the appended claims.
The invention is clearly illustrated in the accompanying drawings, which, with
the letters of reference marked thereon, forming a part of this Specification and
in which,
Figure 1 is a perspective view showing the mouth of the bag closed.
Figure 2 is a sectional detail showing the position of the parts when the bag is
closed.
Figure 3 is a like view with the parts in the position they assume when the bag
is open.
Like letters of reference indicate like parts throughout the several views.
Referring now to the details of the drawings by letter, A designates a bag of any
approved construction provided around its mouth with a gathering string or cord B,
which may be held thereto in any suitable manner, preferably by being secured
within a hem or casing as seen in Figures 2 and 3. The ends of the cord or string
are passed loosely through holes c in the upper part C of the clamp, and may be
united or not as may be desired.
The upper part C of the clamp may be of any suitable material and shape
preferably substantially circular and convex as seen in the several views the edges
being designed to overlap the under part of the clamp as well. as the mouth portion
of the bag as seen in Figure 2.
D is the lower part of the clamp, it may be of any suitable material and of
required shape, being preferably a convex disc; it is held to the upper part near
one edge by suitable means, as the loose pin or bolt a, and is of less diameter than
the outer part C of the clamp.
E is a piece of wire somewhat longer than the normal distance between the two
parts C and D, arranged with its loop or bend projecting through the top of the
upper part and the ends which extend through the lower part, turned outward as
seen in Figures 2 and 3 to prevent withdrawal thereof, yet permit of freedom of
movement of the two parts as will be seen in Figure 3.
F is the locking part; I term it a pawl; it is loosely hinged on the wire or loop
or link E; in its preferred form it is in the shape shown, triangular in longitudinal
vertical section, being hinged at its larger end as shown.
In operation, with the parts in the position in which they are shown in Figure 3,
the bag is open and ready to be filled. When it is desired to close the bag the
cord or string is pulled upon which gathers in the mouth of the bag and brings the
parts into the position in which they are shown in Figure 2, the locking part F
D

page_text: being during this operation in the position shown in Figure 3 to allow of freedom
of movement of the upper and lower parts of the clamp so that they will auto-
matically adjust themselves to place as the bag mouth is drawn together. When
the bag mouth has been drawn together the pawl is turned down into the position
in which it is shown in Figures 1 and 2, when the bottom edges impinge against
the outer face of the upper part of the clamp and the pawl then acts as a wedge to
draw the two parts of the clamp together, the link being free to slide in the holes
in the two parts, and when down in the position shown in Figures 1 and 2 the parts
are locked. To open the bag simply throw the pawl up into the position shown in
Figure 3 when the two parts of the clamp will be released and. free to be separated
and the mouth of the bag opened.
Modifications in detail may be resorted to without departing from the essence of
the invention or detracting from its merits.
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:
1. A bag fastener consisting of two parts hinged at one edge one designed to go
inside the bag the other outside, and adapted to clamp the mouth of the bag
between them, and means. for drawing the two parts together and locking them, as
set forth.
2. A bag fastener consisting of two hinged parts adapted to fit one within the
other, one inside and the other outside the bag to clamp the mouth of the bag
between them, and drawing and locking means loosely connecting the two parts and
adapted to serve substantially as specified.
3. The bag fastener consisting of the two parts both convexly and oppositely
arranged, loosely hinged together, and one adapted to fit within the other one inside
the bag and the other outside the same, a loose connection between the two parts
and a locking part pivotally connected with the said loose connection, as set forth.
4. The combination with a bag and its mouth string, of a two-part clamp one part
arranged within the bag the other outside, the outer part having holes through
which the string is loosely passed, the two parts being loosely hinged together, a
link loosely connected with the two parts, and free to slide in the same, and a
triangular pawl loosely pivoted on the said link outside the outer part of the clamp,
substantially as specified..
