We, THEOBALD MATHEW HACKETT, and EDWARD FRANCIS HACKETT, Merchants,
both of No. 179 Broadway, Albany, New York, United States of America, do
hereby declare the nature of this invention, and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:
Figure 1 is a longitudinal section of part of the box of a vehicle provided with
this crane attachment, the lateral arm of the crane being in its elevated position:
Figure 2 is a like section with the crane arm in its depressed position: and
Figure 3 is a plan view of Fig. 1.
This invention relates to a crane attachment for carts and other vehicles used for
the delivery of heavy commodities which usually require weighing at the place of
delivery and it consists in providing the vehicle with a swinging crane having a
lateral arm that can be swung downwardly when a package is to be hitched thereon
and upwardly when an attached package is to be raised.
;
As represented in the drawing, A designates the after-body of the box of a wagon
or other vehicle used for delivering coal or other merchandise, and which is provided
with this crane attachment.
B designates the crane that is removably attached to the box A, and which
consists of a vertical post, 1, that is fitted to swing in boxes, 2, and is provided
with a lateral arm, 3, that is jointed to the head of said post so as to be swung up
and down when occasion requires, in the manner hereinafter explained. A diagonal
brace, 4, having at or near its middle a joint, 5, and having its opposite ends jointed
to the post 1 and arm 3, forms a support for the latter when extended, and serves
as a means for positively raising and depressing the outer end of said arm. A bent
lever, 6, is pivoted to the head of the post 1, and is connected by a rod, 7, to the
joint 5 of the diagonal brace.
C designates a scale-beam or steelyard, hung to the outer end of the arm of
the crane for convenience in weighing articles delivered from the vehicle. A hook
or other appliance may be attached to the pendent ring of said scale-beam, when
preferred, to facilitate the hanging of bags and other receptacles thereon.

page_text: The manner of operating this invention is as follows: The crane B, whose
arm, 3, should normally range in line with the side of the box A, is swung around
so that said arm will extend transversely over said box, and the arm depressed by
raising the lever 6, as shown in Fig. 2. A package whose weight will rest on the
bottom of the box can then be readily hooked onto the scale-beam C or arm 3,
according to circumstances. Then by depressing the lever 6, so that the inner
limb of said lever will range in line with the rod 7, as shown in Fig. 1, the joint 5
will be forced outwardly to bring the two parts of the brace 4 to range in line
with each other, as shown in Fig. 1, and thereby the arm 3, having the package
attached thereto, will be raised to a horizontal position by a slight expenditure of
power, the brace 4, lever 6,. and. rod. 7. combining to form togglo-joints to accom-
plish that purpose.
When preferred, a crane arranged to swing on its axis, as herein described, but
having a rigid lateral arm provided with a scale-beam, may be substituted for the
jointed crane herein shown and described; but, as in that case the packages would
require to be lifted by hand, a crane made substantially as shown in the drawing is
a preferable form.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we claim
is-
1. The combination, with a cart or other vehicle, of a crane consisting of the
following parts, to wit: a post, 1, which, is pivoted to the box of the cart to swing on
its vertical axis, a tilting arm, 3, that projects laterally from and is hinged to the
head of said post, a jointed diagonal brace, 4, having a hinge-joint, 5, near its middle
and having one of its ends hinged to said posts and its opposite end hinged to said
arm, and a bent lever, 6, that is pivoted to the head of said post and is connected by
a rod, 7, to the joint of said diagonal brace, as and for the purpose herein specified.
2. A crane for coal-carts and other vehicles, consisting of a crane post, 1, laving
a tilting arm, 3, hinged to its head so as to project laterally therefrom, a diagonal
brace, 4, which is hinged at one end to said post and at its opposite end to said arm,
and a lever, 6, that is pivoted to the head of said post and is connected by a rod, 7,
to a joint, 5, of the diagonal brace, as and for the purpose herein specified.
