TRUVIDIONAL SPECIFICATION.
Improvements in Snap Hooks.
1, JOSEPH PICKETT, of New Hope, in the County of Bucks and State of
Pennsylvania, United States of America, Farmer, do hereby declare the nature
of this invention to be as follows:-
My invention relates to a snap hook which is provided with means for increasing
or decreasing the tension of the spring when occasion may demand.
The body of the hook is of the usual shape, being provided at its upper
extremity with an eye, which may be made solid or in the shape of a split ring,
and the said eye may be substituted by a swivel, or any well known attachment to
the body of a snap hook. The lower extremity of the body is preferably reduced
in diameter, forming thereby a shoulder and the main portion of the body has
produced in it a slot or chamber, extending through from its front to its rear edge,
but the opening of the chamber is of greater length at the back of the book than at
the front.
At the back, lower portion of the said chamber a block is usually introduced, and
when employed has bearing against the base wall of the chamber, the block being
held permanently in position by a rivet or its equivalent, and the block is of such
thickness that a space is made to intervene its inner face and the front wall of the.
lower portion of the chamber.
The lower end of a spring is introduced into this opening or space and the upper
end of the spring is preferably slightly curved in a rearwardly direction. A set
screw is carried by the block and the said set screw has bearing against the spring
so that the tension of the latter may be increased or decreased as may be found
desirable. If, however, it is found desirable in practice, the block, instead of being
a separate piece from the body may be made solid or integral therewith; but in
every event the space or pocket is provided for the reception of one end of the said
spring and the set screw is likewise employed.
The tongue of the snap hook is provided at its free end with a recess which receives
the reduced lower portion of the hook body; while the tongue is provided with
a wide body or shank, which body is provided in its rear edge with a step, against
which the curved end of the spring has bearing. The body or shank of the
tongue enters the upper portion of the chamber and is pivoted therein through
the medium of a pin or its equivalent; and the upper forward extremity of the
tongue shank or body has formed thereon a lip which enters a recess in the
upper front portion of the body proper of the snap hook, the lip having bearing
against the rear wall of the recess when the reduced lower end of the body
of the hook enters the recess of the tongue. In this manner when the tongue
is forced forward to locking position with the body, it has bearing upon the
body at both ends and consequently the tongue is enabled to withstand
greater outward tension than when ordinarily constructed and is consequently
much stronger.

I JOSEPH PICKETT of New Hope in the County of Bucks and State of
Pennsylvania, United States of America Farmer 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 :-
My invention relates to improvements-in-snap hooks and it has for its object to
provide a hook of this character with means for increasing or decreasing the tension
of the spring when occasion may demand.
The invention consists in the novel construction and combination of the several
parts, as will be hereinafter fully set forth and pointed out in the claims.
Reference is to be had to the accompanying drawings forming a part of this
Specification, in which similar figures and letters of reference indicate corresponding
parts in all the views.
Figure 1 is a partial longitudinal section through the hook;
Figure 2 is a rear edge view thereof; and
Figure 3 is a front elevation of the hook.
In carrying out the invention, the body A of the hook is given the usual shape,
being provided at its upper extremity with an eye 10, which may be made solid or
in the shape of a split ring as illustrated, and the said eye may be substituted by a
swivel, or any well known attachment to the body of a snap hook. The lower
extremity of the body preferably reduced in diameter, forming thereby a
shoulder 11; and the main portion of the body A has produced in it a slot or
chamber 12, extending through from its front to its rear edge, but the opening
of the chamber 12 is of greater length at the back of the hook than at the
front.
At the back, lower portion of the said chamber 12 a block 13, is usually
introduced, and when employed has bearing against the base wall of the chamber,
as shown in Figure 1, the block being held permanently in position through the
medium of a rivet 14, or its equivalent, and the block is of such thickness that a
space 15 is made to intervene its inner face and the front wall of the lower portion
of the chamber, as is likewise shown in Figure 1.
The lower end of a spring 16 is introduced into this opening or space 15, and
the upper end of the spring is preferably slightly curved in a rearwardly direction,
as is also shown in Figure 1. A set screw 17, is carried by the block 13, and the
said set screw has bearing against the spring 16, so that the tension of the latter
may he increased or decreased, as may be found desirable. If, however, it is foun.l
desirable in practice, the block 13, instead of being a separate piece from the body
may be made solid or integral therewith; but in every event the space or pocket 15,
is provided for the reception of one end of the said spring. 16, and the set screw 17,
is likewise employed.
The tongue 18 of the snap hook is provided at its free end with a recess 19, which
receives the reduced lower portion of the hook body A; while the tongue is also
made with a wide body or shank 18, provided in its rear edge with a step 20, against
which the curved end of the spring 16 has bearing. The body or shank of the
tongue enters the upper portion of the chamber 12, and is pivoted therein through
the medium of a pin 21 or its equivalent; and the upper forward extremity of
the tongue shank or body has formed thereon a lip 22 which enters a recess 23
in the upper front portion of the body proper of the snap hook, as shown in
Figures 1 and 3, the lip having bearing against the rear wall of the recess 23 when
the reduced lower end of the body A of the hook enters the recess 19 of the tongue.
In this manner when the tongue is forced forward to locking position with the body,

page_text: it has bearing upon the body at both ends, and consequently the tongue is enabled to
withstand greater outward tension than when ordinarily constructed, and is
consequently much stronger.
It will be understood that the spring may be made straight, if in practice it is
found desirable.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is
1. A snap hook, the same consisting of a body provided with a chamber
therein and terminating at one end in a hook,-a tongue pivoted in the body
and adapted for engagement with the hook extremity of the body, a spring located
in a pocket formed in the chamber and having bearing against the rear of the
tongue, and means substantially as described, for imparting tension to the spring,
as specified.
2. A snap hook, the same consisting of a chambered body terminating at one
end in a hook, the chamber of the body being provided with a pocket near the
hook end of the body, a tongue recessed at one end to receive the hook extremity
of the body and provided at its opposite end with a lip adapted for simultaneous
engagement with the upper portion of the body, the said tongue being likewise
provided with a wide shank pivoted in the chamber of the body and a spring, one
end of which is entered in the pocket of the said chamber, the other portion of
the spring having bearing against the shank of the tongue, as and for the purpose
set forth.
3. In a snap hook, the combination, with a body having a chamber formed
therein and terminating at one end in a hook, and a block secured in the rear
lower portion of the chamber, forming a pocket in the lower portion of said
chamber, of a tongue provided with a recess adapted to receive the hook
extremity of the body, said tongue being further provided with a shank integral
with it and of greater width, the said shank being pivoted in the chamber of the
body, a lip projected from the shank, entering a recess in the body and engaging
with the rear wall of the recess simultaneously with the engagement of the tongue
with the hook of the body, a spring located in the pocket of the body chamber and
having bearing against the shank of the tongue, and an adjusting screw having
bearing against the spring, whereby the tension of the spring may be regulated, as
and for the purpose set forth.
