POST CLAMP CHAIN
John C. Bishop, Savannah, N. Y.
Application August 27, 1937, Serial No. 161,201
1 Claim.
My invention relates to improvements in post
clamps.
In driving fence posts and the like into the
earth the posts are very often split and become
5 unsuitable for further use requiring that they be
removed and replaced with new posts. Particu
larly is this true where the posts must be peri
odically driven down after being raised by frost
in the ground and other reasons.
It is the main object of my invention to pro
vide a clamp which may be readily wrapped and
drawn tight around the post while it is being
driven and which will support and prevent the
post from splitting.
Another object is to provide a clamp of this
kind in simple and inexpensive form and adapt
able to use on posts of any sizes commonly em
ployed.
Another object is to provide a clamping de
20 vice of this kind including a chain to encircle
the post and a clamping device for drawing the
chain tight around the post, the said clamping
device comprising a base plate to which one endv
of the chain is adjustably connected and which
25 for this purpose has a plurality of hooks stag
gered apart a distance less than the length of
one chain link so as to give some nicety of ad
justment of the chain, and a hand lever pivotal
ly mounted on the base plate and attached to
30 the other end of the chain, the arrangement be
ing such that swinging the lever to a “closed”
position will pull the chain tightly around the
post.
With these and other objects in View the in
35 ‘vention resides in the novel construction and ar
rangement of parts as hereinafter fully set forth
and claimed, reference being had to- the accom
panying drawing as showing a preferred em
bodiment of my invention for purposes of ex
40
empli?cation.
In the drawing:
Figure l is a plan view of a post showing my
clamp applied thereto.

slightly along its longitudinal line so as to pro
vide a concaved inner or post engaging face 8.
At one end an outwardly turned and ?attened
ear 9 is extended from the base plate and same
has an aperture ID to receive the pivot pin or 5
rivet H by which the hand lever I2 is connected
to the base plate. This lever [2 has the forked
end l3 forming a cleft M to receive the ear 9
and with apertures £5 to receive the said pin
ll. Thus the hand lever [2 may swing toward
or away from the base plate 1 on its ear 9.
The opposite end of the base plate has a chain
hook l6 locatedto one side of the center line of
the plate and has another hook [6a at an equal
distance to the other side of the center line but
located inwardly from the end of the plate a
distance equal to about half the length of one
of the links 611 of the chain 6. The hooks l6
and I600 are thus “staggered” and both are
formed by turning out a portion of the base plate
itself, the inner hook Isa being set inwardly by
cutting into the plate as indicated at [1.
Just outwardly of its forked end l3 the hand
lever I2 is given a bend or offset I8 to the side
so that the handle portion of the lever stands
at an oblique angle and to one side of the forked
end as shown. At the junction of the forked
end 13 and the bend [8 a notch 20 is formed
angularly into the lever so as to provide a re
taining lip or hook 2| and one end of the chain 30
6 is provided with an elongated end link 6b
which will slip over the lever and into this notch.
In use now the base plate 1 is rested with its
concaved face 8 against the side of the post A
near its upper end and the hand lever I2 swung
outward from the post as shown in Figure 1.
The free end of the chain 6 is then placed around
the post and pulled tightly by hand and a link
hooked over either of the hooks l6 or Ilia. Any
excess chain may hang down free alongside the
post. The hand lever I2 is then swung over in
the direction indicated so that the end link 62)

Referring now with more particularity to the
drawing my invention comprises a clamping de

and the resulting endwise pull on the chain will
draw it tightly and ?rmly around the post so
that the post may be driven without splintering.
When the link 61) moves inwardly past the pin II
the pull of the chain holds the lever [2 in this
“closed” position as indicated in broken lines in

While I have herein set forth a certain pre

last mentioned hook at some distance from the
margin of the widened end of the plate, a hand 10
lever pivoted to the ear on the plate, and a
chain connected to the hand lever and adapted
to be selectively engaged with the said hooks as
and for the purposes described.
