pivotally mounted in the fork by a substan-
tially vertically extending pin 19. A draw
bar is connected to the rear end of the block
18, and has its forward part in the form of a
5 cylinder 20 provided with a pair of for-
wardly projecting ears 21 to receive the for-
ward end of the block 18 therebetween, and
to also receive the pivot pin 22 which en-
gages the ears and the said block. A knuckle
10 joint is thus provided between the fork pin
and the draw bar, which admits of the ver-
tical and horizontal flexing of the forward
end of the towing device.
The cylinder 20 is provided, near its for-
15 ward end, with an internal shoulder 23
against which is adapted to engage a plunger
disk 24 which is mounted upon the end of a
plunger rod 25, and held thereto by means
of the plunger head 26. A coil spring 27
20 surrounds the plunger rod 25 and bears
against the disk 24 to hold the latter against
the head 26. The head 26 is of less diameter
than that of the disk 24, and adapted to
move into the forward reduced portion of
25 the cylinder 20. The other end of the coil.
spring 27 engages an internal shoulder 28, in
the form of a collar, which is suitably se-
cured within the cylinder 20 adjacent to the
rear end of the same. The plunger rod 25 is
30 also provided with a collar 29 adjustably
mounted thereon and of a diameter adapted
to move freely past the collar 28 of the cyl-
inder. The rear end of the spring 27 is suit-
ably reduced for engagement with the collar
35 29 to hold the spring 27 under the desired
tension against the disk 24.
The rear end of the plunger rod 25 is
pivotally connected by means of a substan-
tially horizontally disposed pivot pin 30
40 to a link 31 which in turn is connected to a
rear yoke or bracket 32 in the, form of a
flat bar having its opposite ends extending
rearwardly for engagement across the front
axle C of the vehicle to be towed. The rear
45 ends of the yoke 32 provide clamping plates
33, and the latter are provided with down-
wardly extending elongated threaded bolts
34 which are pivotally connected at their
lower ends to chains or other flexible mem-
50 bers 35 adapted to encircle the axle C ad-
jacent to the opposite ends thereof. Links
36 are mounted upon the ends of the chain
35 and are adapted to engage over lips 37
formed upon the rear free ends of the plates
55 33. Wing nuts 38 are threaded upon the
upper ends of the bolts 34, to raise the same
and bind the chains 35 about the axle, the
nuts 38 preferably projecting downwardly
through the plates and about the bolts 34
60 to guide the same.
The link 31 is pivotally connected at its
rear end to the yoke 32 by means of a bolt
or pin 39 which preferably projects up-
wardly through the yoke 32 and through
66 the link 31. A steering bar 40 is providedwith a longitudinally extending slot- 41
therein, through which the pin 39 is adapted
to project. The steering bar 40 is adapted
to engage against one side of the link 31,
and the latter is of relatively flat formation 70
and provided adjacent its lateral edges with
a pair of opposed ribs or lugs 42 for engage-
ment against the opposite edges of the steer-
ing bar 40. The steering bar 40 is adapted
to be moved longitudinally between the ribs 75
42 and upon the pin 39. A clamp 43 is
adapted to be secured to the steering rod F
at any suitable point, and is connected to the
rear end of the steering bar 40 by means of
a knuckle 44. The clamp 43 is preferably 80
in the form of a body member having an
arcuate portion adapted to extend over one
side of the steering rod F and which is pro-
vided with a correspondingly formed clamp-
ing plate for engagement against the oppo- 85
site side of the steering rod F, and which is
connected by means of a bolt 45 to the body
of the clamp 43. The bolt 45 is adapted to
be relatively long, for adjusting the clamp
43 to steering rods varying in thickness. 90
The front yoke 10 may be provided in-
termediate the arms thereof with a for-
wardly extending hollow shank or sleeve
portion 46 into which is threaded a jack
screw 47 having an angularly faced head 48 95
upon its outer end, and provided with a
guiding and anchoring pin 49. This brace
member so formed, is provided with a head
portion 50 adapted to engage against the
rear side of the differential gear housing 100
B, and is of such configuration as to sub-
stantially conform to the contour thereof.
The pin 49 projects into the head 50 and
forms substantially a swivel joint between
the screw 47 or the brace arm, and the 105
head 50.
The bolt 39 is preferably provided with a
bushing 51 as shown in Fig. 5, which pro-
jects through the link 31, the slot 41 of
steering bar 40, and through the bracket 32. 110
A washer is seated against the free end of
the bushing and superposed nuts 52 are
turned tight upon the bolt 39 to hold the
same in the bushing and through said mem-
bers. 115
When it is desired to apply the towing
device of this invention, it is only necessary
to release the screws 16 of the front clamps
sufficiently to disengage the links 14 from
the lips 13. The front yoke 10 is now ap- 120
plied to the rear axle A, the chains 15 are
wrapped about the axle, and the links 14
are engaged over the lips 13. The nuts 17
are now tightened to bind the chains 15
about the axle for holding the yoke 10 125
rigidly thereto. In order to brace the axle
against any undue strain, the head 50 is
placed against the housing B of the axle,
and the screw 47 is turned up against the
head 50 to brace the same. The rear yoke 130
