The letter A designates the axle, and the wheels A guard-plate, C, extends
lengthwise on top of the axle, and each end curves upward therefrom, as it d, and
passes over the top rim of one wheel and then down on the outer side thereof, as at e,
and attaches to the extremity of the axle-arm By this construction the parts d of
the plate which pass over the wheels serve as guards, and as a seat for boxes and biles,
and the depressed central portion between the said two guards serves is sent for the
rounded side of a barrel or similar package This depressed central part of the plate, C,
may have two pointed prongs, f, to enter slightly into the wooden sides of the baricl,
and thereby prevent it from slipping A straight tongue, G, is attached to the axle,
and projects therefrom any desired length It must be long enough to serve all the
purposes of a tongue or handle for shifting or controlling the truck
In cross-section the tongue is rectangular in shape, as shown in Figure 4, and
short distance from the axle are two arms, h, projecting at opposite sides of the tongue
These two arms serve the same end that a cross-bar would, and support two pointed
prongs 2, which will enter the sides of the barrel or box and prevent it from rolling oi
slipping
A dog, J of peculiar construction, is attached to the tongue and has two movements,

page_text: a pivoted or tilting movement in a vertical plane coincident with the length of the
tongue, and a sliding movement lengthwise of the tongue The body of the dog has
a long slot or loop, k, which is occupied by the tongue G The two long sides of the
loop, k, fit loosely against the fint sides of the tongue, but the length of the loop, k,
is so much greater than the greatest breadth of the tongue that room is afforded for
the dog, J, to pivot or tilt in vertical plane coincident with the length of the tongue.
It will be observed that while the dog may slide lengthwise of the tongue it so fits
the flat sides of the tongue that it will not turn latterally or revolve thereon
At one
end of the loop-body is hook, l, which is to engage with the uppermost chine
of a barrel, or the edge of box, and at the opposite end of the loop-body is a
handle, m
By grasping the handle, m, the dog may be tilted to turn up the hook, l, and
thereby disengage it from the barrel chine, as indicated by broken lines in Figure 1,
or the dog may be moved lengthwise of the tongue
The construction of the dog for handling boxes or bules varies from that for a
barrel, this is shown in Figures 5, 6 and 7 In this case the tongue or handle, G,
has pins, n, projecting from each side, in the present instance three pins are shown
The dog, J, has hooks, o, on its under edges, each of the two parallel bars which
form the slot or loop, k, are provided with the hooks o In the present instance four
hooks are on eich bar These hooks, o, engage with the pins, n, and serve to form a
pivot-connection between the dog J and tongue G, as shown in Figure 5, it will be
seen the dog may have either of its four hooks, o, engaged with either of the pins to
make the hook-end of the dog short or long, to suit the particular box or bale th it is
to be handled Thus one truck is perfectly adapted to handle boxes or bales of
varying sizes
The slot, h, of the box-dog is provided near the handle with a cross slot, n', which
is formed by an outward curve, p, on eich parallel bir, this cross slot, n¹ serves to
pass over the pins, n, on the tongue, so is to shift the position of the dog along the
tongue from one pin to another
L
For conveniently supporting the box-dog J when the truck is not in use, it is
provided near its handle with socket or loop 9, and the tongue G of the truck has on
its lower edge a hook, r, with which the said loop, q, on the dog may engage, thus
the dog may be suspended from the hook r
Having now nortionlorly desombed and ascertained the nature of my soud Invan
1st In a hand-truck, the combination of the axle A, wheels b, the tongue G connected
to the axle, the cross-arm h with prongs secured to the tongue, and the slotted
dog J connected to the tongue and vertically adjustable thereon, as shown and
described
2nd In a hand-truck, the combination of the axle A, wheels b, a guard-plate, C,
bent to rest on the top of the axle, as shown, said plite curving upward and passing
over the wheels b, and bent downward and attached to the ends of the axle, tongue G,
and a slotted dog, J, vertically adjustable on said tongue, substantially as specified
3rd In a hand-truck, the combination of the axle A, wheels b, a tongue G, connected
to the axle and provided with side-projecting pins n, and a dog J having a
longitudinal slot and a cross-slot and provided on its under edge with hooks o,
whereby the dog may be shifted and pass any of the said pins so as to be engaged
with any desired pin
