ALFRED A. LOYER, OF LAREDO, TEXAS.
TOWING DEVICE FOR VEHICLES.Specification of Letters Patent.
Patented Dec. 3,.1918.
Application filed May 26, 1917. Serial No. 171,251.
To all whom it may concern:
Be it known that I, ALFRED A. LoYER, a
citizen of'the United States, and a resident
of Laredo, in the county of Webb and State
5 of Texas, have invented a. certain new and
useful Improvement in Towing Devices for
Vehicles, of which the following is a specifi-
cation.
The present invention relates to an attach-
10 nent for self-propelled vehicles, and has
more particular reference to a means for
connecting two or more of the same together
to tow a disabled vehicle. -
An object of the present invention is to
15 provide a towing device of this character
which may be quickly and easily applied to
the vehicles, which is adapted not only to
draw the towed vehicle, but to also guide the
same so that an operator is not required in
20 the towed vehicle, and to provide a towing
device with shock-absorbing means adapted
to operate upon the forward impulse of the
towed vehicle, as well as upon the starting
or jerking of the driving vehicle.
25 The invention further aims at the provi-
sion of a towing device embodying these
characteristics, and which is adapted for ap-
plication to the axles and steering rods of
motor vehicles, and which may be readily
so adjusted and applied to vehicles of various
types.
The above, and various other more or less
important features and advantages of this
invention will be in part described, and in
35 part understood, from the following detailed
description of the present preferred embodi-
ment, the same being illustrated in the ac-
companying drawings, wherein:
Figure 1is. a plan view of a towing device
40 constructed according to the present inven-
tion, shown partly in section, and as applied
to the front and rear axle portions of two
different vehicles.
Fig. 2 is a side elevation of the same,
45 partly shown in section, the vehicle portions
being also shown.
Fig. 3 is a transverse section taken on the
line 3-3 of Fig. 1, enlarged and showing
one of the adjustable clamps for the rear
50 yoke of the device.
Fig. 4 is a similar view taken on the line
4-4 of Fig. 1, showing one of the adjustable
clamps carried upon the forward yoke of the
device.
6$ Fig. 5 is a fragmentary enlarged view in
longitudinal section, taken substantially onthe line 5-5 of Fig. 1, through the pivotal
connection of the steering bar adapted for
connection with the forward end of the ve-
hicle to be towed. 60
Fig. 6 is a detail enlarged view in section,
through the intermediate brace carried upon
the forward yoke of the device, for reinforc-
ing the rear axle of the driving machine.
Fig. 7 is a fragmentary enlarged section 65
taken longitudinally substantially on the
line 7-7 of Fig. 1, through the draw bar
cylinder and the parts mounted -therein.
Fig. 8 is a transverse section taken on the
line 8-8 of Fig. 1. 70
Referring to these drawings, wherein like
parts are designated by similar characters of
reference throughout the several views, A
designates the rear axle of a driving machine,
provided in the usual manner, with a differ- 75
ential gear casing B. C designates the front
axle of a machine or vehicle adapted to be
towed or drawn, the same having the usual
road-engaging steering wheels D pivotally
mounted upon opposite ends of the axle C so
and having steering arms E extending rear-
wardly from the axle and connected together
by means of a steering rod F.
The towing device comprises a front yoke
10 provided with rearwardly converging 85
arms terminating in a transversely extend-
ing fork 11. The forward ends of the yoke
10 extend forwardly- substantially in paral-
lelism and may be arched upwardly to a
slight extent to fit over the upper side of the 90
rear axle A, as shown to advantage in Fig. 4.
These arched portions of the yoke arms com-
prise clamping plates 12, and the latter are
provided upon their forward ends with
slightly upturned lips 13 adapted to receive 95
thereover the upper ends of links 14 carried
upon the ends of chains, or other flexible,
members 15, adapted to encircle the lower
portion of the axle A beneath the plates 12,
and which are hingedly connected at their 100
free ends to elongated threaded bolts 16.
The bolts 16 extend upwardly through the
arms of the yoke 10 against the rear side of
the axle A, and wing nuts, or the like, 17 are
threaded upon the upper ends of the bolts 16 10 5
and are provided with depending cylindri-
cal projections adapted to surround the bolts
16 and to extend downwardly through the
arms of the yoke.
A knuckle block 18 is provided upon its 110
forward end with a tongue adapted to fit be-
tween the arms of the fork 11, and which isi,286,367
