GAFF HOOK
Louis H. Darling, Vallejo, Calif.
Application August 13, 1936, Serial No. 95,935
4 Claims.
This invention relates to a gaff hook.
The primary object of the invention is to pro
vide a gaiT hook that may be folded so that the
point of the hook may be held in the handle
5 where it cannot cause injury.
Another object resides in the ease and safety
with which the device may be transported. In
the folded position the hook may be packed in a
space approximately one-half the size ordinarily
10 required to carry such hooks.
Other objects and advantages of the device
will become apparent from the description and
drawing of the device.
Referring to the drawing:
15
Figure 1 is a front elevation of the device in
extended position;
Figure 2 is a side elevation of the same, with
the folded position of the hook shown in dotted
lines;
20
Figure 3 is a fragmentary sectional View show
ing the bill of the hook engaged in the handle;
Figure 4 is a fragmentary sectional view on an
enlarged scale on the line 4-4 of Figure 1;
Figure 5 is a cross sectional view on the line
25 5--5 of Figure 1;
Figure 6 is a cross sectional in‘ew 0n the line
5-6 of Figure 1; and
Figure 7 is a detail View on the line -|--'| of
Figure 3.

Referring more specifically to the drawing,
wherein like reference characters designate like
or similar parts, the hook Ill has its shaft Illa
secured to a section || of the stem, by rivets I2.
The section || is pivoted to the section I 3 by a
35 pin ll-l. The pin I4 being enclosed by a coil
spring I5 having its opposite ends bearing against
the section || and the section I3 to- normally hold
the device in an extended position.
The section I3 of the stem extends up into a
40 longitudinal recess Il in the handle I6, and is'
secured to the handle by a rivet I8.
The sections || and I3 of the stern are chan
nel shaped, the section I I being smaller than the
section I3 so that it ñts in the section I3.
45
A sliding catch having a housing I9 is secured
by rivets 2li in the channel section II. The
sliding catch having a laterally extending pin 2 í,
sliding longitudinally in a slot 22 in the sides of
the section II, engages in the notches 23 in the
50 opposite sides of the channel section I3. The
pin 2| extends through the opposite sides of a U
shaped plate 24` The plate 24 has a button 25
secured to it by a stem 26. The plate I9 has a
longitudinal slot 2l for the stem 26 to slide in.
55 A coil spring 23 is attached to the pin 2| and one
(Cl. 43--5)
of the rivets 20. 'I'he button 25, secured to the
U-shaped plate 24, being moved longitudinally
in the slot 2l moves the pin 2| which passes
through openings in the opposite sides of the U
shaped plate 24, against the action of the spring 5
28, to release the pin 2| from engagement with
the notches 23. The notches 23 have inclined
lip-s 23a to permit the pin 2| to automatically
engage the notches 23 against the resistance of
the spring 28.
10
A sliding catch is carried in the recess I1 of
the handle I6 and comprises a plate 29 with a
V-shaped notch 30 in one end thereof, the op
posite end being bent to form a flange 29a.
The handle I6 has a slot 35 registering with the 15
notch 3l) in plate 29 to receive the bill of the
hook I0. A button 3| is secured to the plate 29
by a stem 32, and is movable in a slot 33 against
the action of a coil spring 34 secured to the sec
tion I3 and the flange 29a, to release the bill of 20
the hook I0 from engagement with the notch 30
of the plate 29.
In operation assuming the device to be in
extended position, by pressing the butto-n 25, the
U-shaped plate 24 Will move the pin 2| in the 25
slot 22 against the action of the spring 28 to
release the' pin 2| from engagement in the
notches 23. The hook can then be moved against
the action of the spring l5 to the closed position
as shown in Figure 3.
To open the device the 30
button 3| is moved longitudinally in the slot 33,
against the action of the spring 34, to release
the bill of the hook I0 from engagement with the
notch 39 of plate 29. The spring I5 will cause
the hook to swing to the open position. The pin 35
2| will slide over the bevelled lips 23a and engage
the notches 23 to hold the device in open position.
I claim as my invention:
l. A folding gan“ hook, comprising a handle, a
hook, and a stem having two sections pivotally 40
connected together, a sliding catch carried by
one of said sections, and cut-away portions in the
other section to cooperate with the catch to
hold the device rigid when in open position.
2. A folding gaiï hook, comprising a hook, a 45
handle, and a stem having two sections pivotally
connected together, said handle being hollow to
receive a sliding catch, the handle also being pro
vided with an opening to register with the catch,
said opening being adapted to receive the point 50
of the hook, said hook being held in folded posi
tion by said sliding catch.
3. A folding gaff hook, comprising a handle,
a hook, a stem having two sections pivotally con
nected by a pintle, a coil spring carried by said 55
2
2,112,765
pintle, the opposite ends of said spring bearing
against the sections to urge the hook to an open
position, said handle being hollow to receive a
sliding catch to hold the device in folded posi
tion, and a latch carried by one of said sections,
the other section being provided with> recesses to»
cooperate with the latch, said coil spring normally
urging the hook to open position, said latch
holding the sections in extended position.

4. A folding gaff hook, comprising two sec
tions pivotally connected by a pintle, said pintle
carrying a coiled spring, the opposite ends of
said spring bearing against the sections to nor
mally urge them to an open position, one of said
sections being provided with a sliding catch, and 5
the other section having cut-away portions to
cooperate with said catch to hold the sections
rigid When in open position.
