Improvements in and relating to Bill-hooks or Files.
I, GEORGE WASHINGTON HALL, a citizen of the United States of America,
residing at No. 221 E. Street N.W., in the City of Washington, District of
Columbia, United States of America, Clerk, 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 invention is a hook or needle on which a piece of paper may be conveniently
hung by a single movement, and a spring catch by which the paper is held against
blowing away.
Figure 1 is a side elevation of a hook and detent, for attachment to a wall or
desk.
Figure 1 is a face view thereof.
Figure 2 is an elevation and partial section of a bill hook attached to a
bracket.
Figure 3 is a side view of a needle and guard attached to a paper weight.
Figure 4 is a broken front view of slotted spring.
Figure 5 is a side view of paper weight with hook attachment.
A, indicates a stiff wire or rod sharpened at the end and preferably bent into the
form of a hook. One end of this rod or wire, as at B. is screw-threaded and pointed,
so that the screw-threaded part may bore its way into a board for attaching the
hook. A button or shoulder, C, is permanently secured to the hook at the end of
the screw-threaded portion. The hook, A, has a reflex curve, D, near the pointed
upper end.
A flat spring, F, is perforated for the passage of the screw-threaded part, B, of
the hook. The spring has a bend at G, and is slotted lengthwise along this bent
portion as shown at, Ĥ, Figure 4. The spring, when clamped by the button or
shoulder, C, of the hook, is pressed forward so that the slotted portion of the spring
straddles the reflex curve or return bend of the hook.
Referring now to Figure 1, if a sheet of paper be pressed against the point, I, of
the hook and then drawn down, the sheet will press back the spring, F, and will
slide down past the curve, D, of the hook until it rests against the button or
shoulder, C, the hook having made its own perforation in the paper. The spring, F,
will move back astride of the curve, E of the hook, and will thus form a stop or
catch to prevent the paper from being too readily lifted or blown away. But
by taking hold of the bottom of the paper and lifting upward, the spring will be
forced back again, by the movement of the paper, and the sheet may be drawn off
the end of the hook.
In Figure 2 the construction is similar, except that the screw part, C, of the
hook enters a wooden or metallic bracket or holding piece, M, and the spring F is
clamped between the two. The bracket, M, may be attached to the wall by nails,
screws, or otherwise.
By a slight modification, as indicated in dotted lines, Figure 2, the spring may
be attached near the top of the bracket and extend downwardly with a reflex or
return bend. Such construction is a little more expensive, as a separate screw or
fastening device, O, is required.
In Figure 3 the sharpened rod, A', is shown attached to a base or paper-
weight, P. The slotted spring, F', has a more pronounced curve than in the other
constructions, to compensate for straightness of the needle or spindle. The papers
are applied to this form of holder and removed in the same manner as in the
construction hereinbefore described.
It will be observed that by reason of the angle at which the hook or spindle and
D017

page_text: the slotted portion of the spring approach each other, it will be easy to apply or
remove a paper from the hook or spindle, and at the same time the spring will
form an effective check against the removal of papers from the spindle or needle,
except by a pull in the direction of the length of the hook or needle.
The spindle or hook should be so rigid that it will not yield in applying papers.
The plate spring should be light and yielding, to permit the ready application and
removal of papers, but should be strong enough to prevent the papers from blowing
away.
In Figure 5 the wire or needle, A2, is supported on a base or paper weight, P,
and the spring, F1, straddles the reflex curve of the needle. This is practically the
hook of Figure 1 applied to a paper weight.
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. The hook having a reflex bend, and means for attaching said hook to its
support, and the slotted spring partially embracing the bend of the hook.
2. The novel construction of the hook or needle and the guard therefor embracing
said needle.
