EMERGENCY TIRE T001»

direct and mesne assignments, to Rhoda Fairer,

Application February i8, 1938, Serial No. 191,295
i4 Claims.
The present invention relates to tools for ap
plying tire chains.
A form of tire chain frequently used in` emer
gencies and commonly known as an emergency
5 chain consists _of a pair of short chains con
nected at their ends by cross bars. From one bar '
extends a suitable strap usually of , fabric and
the other cross bar is provided with clamping
means for the strap. These chains are applied
by passing the strap around the tire so that
the chains lie on the tire tread transversely
thereof. The strap is then passed through the
clamping means, drawn taut and held by the
15
clamp.
In so applying the chain without the use of
tools, it is practically impossible to prevent soiling
of the hands and clothing.
\
One important object- of the present inven
tion is to provide a novel tool adapted to sup
20 port and hold such an emergency chain during
application, the tool being provided with a handle

l
The type of emergency chain commonly used
and for which the present invention is particu
larly adapted is indicated generally at I0 and
the tool itself is indicated generally at il.
The emergency chain includes a clamp com- lo
prising a flat plate forming a body i2 having a
transverse slot 'i3 adjacent one edge and an in'
clined lip Id extends from the body I 2 at the
edge oi this slot nearer 'the said edge.- A pair
oi ears i5 are carried by the body i2, these ears 16
extending at right angles to the body and being
located at the opposite side edges thereof. Ex
tending frorn the face of the body is a pair of
confronting L-shaped lugs'it spaced on oppo
site sides of the center line of the body- I2. 20
Chain loops il are 'fixed to the vbody i2 on' op
posite sides of the pair or” lugs I6. A clamping
tongue i8 is provided with laterally projecting
opposed trunnions or journals I9 adjacent one
and being so constructed and arranged as to
afford means for carrying the strap around the
tire and bring its end forward into position end, and these trunnions or journals fit on the 25
25 where it may be readily grasped without one’s
hands or clothing coming into contact with the 'ears i5 so that the tongue is pivoted to the body
in such manner that its pivotal action biases
tire or any other part of the vehicle.
A second important object of the invention is the short end 2t of the tongue toward and
to provide a novel tool for this purpose which from the lip iii. Extending from the loop I1
30 can be adjusted to accommodate variations in is a pair of chains 2l each having one end con- 30
the lengths of the chains and especially of the nected to a respective loop I'I and its other
end connected to an opening 22 formed in one
strap portion oi such chains.
A third important object of the invention is arm 23 of a plate 2d of general Y-shape. The
to provide such a tool with means to hold the stem of this plate 2d is provided with a trans-y
verse slot or opening 25 wherethrough passes 35
35 clamp end of the chain, the means being of such
one end portion of a strap 26, the end being
construction that it may also be used for actuat
ing the clamp to cause it to grip the strap upon doubled back to form a loop and being secured
by rivets 2l or the like. This strap is of proper
application of the emergency chain to a tire.
With the above and other objects in view, the f‘size to pass through the slot I3 and is ofproper
thickness to be gripped between the tongue end 40
40 invention consists in general of certain novel
details of construction andcombinations of parts '20 and lip Ii upon the tongue i8 being rotated
hereinafter fully described, illustrated in the ac .to bias the end 20 towards said lip. .
The tool includes a straight metal bar 28 form

of spaced openings 35. Fixed in the lower hole
is a stud or dowel 36. 'I'he strap support also
includes a lower section 31 of bar metal having a
straight upper end portion and a lower end por
tion curved toward the handle end of the tool.
'I'he upper portion of the member 31 is provided
with a series of holes 38 spaced at the same dis
tance as the holes 35 and, in assembling the de
10 vice, the dowel 36 is inserted in one of the holes
38 and the bolt 39 is inserted through the next
hole 38 above the dowel. Fixed to the under side
of the lower end of the member 31 is a strap hook
48 comprising a bent ilat strip preferably of
spring metal for engaging and holding the vend
15 of
the strap 26, as shown in Figure 1.
In the‘modiñcation shown in Figure 8, a-strap
holding hook 40a, preferably made of spring
metal, is bent similarly to hook 40 and extended
20 so as to form a spring clamp with the lower end
of strap supporting bar 36. This clamp will serve
to prevent the strap 26 from slipping during the
use of the tool.
_
ì
In using the device, the body 28 is ‘seated be
25 tween the arms 23 of the plate 24 with the strap
beneath the body 28. The chains are arranged
to rest on the bar 33 and the hook 29 is engaged
between the lugs I6, as in Figure 2. 'I‘he strap is
now led around the concave face of the member
30 31 and its end engaged in the hooks 40 or `40a.
'I’he emergency chain is now ready for applica
tion. To apply the emergency chain, the mem
ber 31 is passed to the inner side of the tire with
the body 28 extending transversely of the tire.
35 'I‘he member 31 then has its hook end passed be
tween -the wheel spokes or through one of the
wheel center openings provided in many disc
wheels, the passage being effected from the inner
to the outer side of the wheel so that the end of
40 the strap is positioned for convenient grasping.
The strap end is now removed from the hook 48
and the strap pulled forwardly. Next the chains
are pushed off the bar 33 and the clamp released
from the hook 29. The tool may now be removed
45 as itis free from the emergency chain. The strap
is now passed through the slot I3 and pulled taut
and the tongue I8 is rotated to cause gripping of
‘ the strap between the end 28
and lip I4, this
operation being facilitated by engaging the tongue
50 end, as in Figure 3, in the gap 3|, the tool thus
acting as a lever.
Obviously, this operation is
effected without'it being necessary for the dirty
tire to come in contact with one’s hands or cloth
mg.
'I‘here has thus been provided a simple and ef-I
ñcient device of the kind described and for the
purpose specified.
,
It is obvious that changes may be made in the
form and construction of the invention Without
A60 departing from the material inventive principles.
It is not, therefore, desired to confine the inven
tion to the form herein shown and described, but
it is desired to include all forms which come with
in the scope of the appended claims.
