page_text: 1, EDWARD GRANDY of Custom House Docks, Dublin, Ireland, Docks Manager do
hereby declare the nature of this invention to be as follows:-
:-
This Invention has reference to improved apparatus for weighing corn in a con-
venient and expeditious manner; and is especially designed for dealing with sacks of
corn shipped in accordance with the rules of the Liverpool Corn Trade Association-
namely in drafts of three bags.
For this purpose a suitably constructed platform is erected adjacent to the vessel in
connection with which it is desired to carry on the operation of weighing.
On the platform is erected a scales constructed in the following manner-
The stand of scales is composed of three iron legs of suitable length and thickness
having eye at upper end and connected by an iron bolt secured by head washer
and key-From this bolt is suspended an iron shackle about twelve inches long-
These legs stand in sockets of V shaped triangle iron lying flat athwart and fixed
to stage by bolts-At the apex of this stand is mounted the scale beam of suitable
length, provided with double hooked swivel gear, and links, to hang scale the bottom
of which is composed of a circle of oak and deal placed transversewise, oak upwards.
Secured to this by collar screw and nut is one centre staunchion of iron terminating
in a hook and bearing at a suitable height from scale bottom a three eyed iron plate
resting on a shoulder to which are attached by hooks three iron stays curved outward
and fixed at equal distances to edge of scale bottom, by collars screws, and nuts.
Three iron stays connect the outer stays with a centre key plate, placed upon
thus divided into three
staunchion at about two feet from scale bottom-The scale
cribs which are numbered from right to left, and the stay between one and three
painted white.
.
Placed athwart the stage are two uprights carrying a cross bar of iron having head
at one end and screw and nut at the other end-on this cross bar between the
staunchions is placed a piece of barrel.

page_text: The scale is worked in the following manner-
Having been loaded with three bags (standing on their ends) from the hatchway the
draft is weighed and the bag from number one crib is canted over cross bar and
vacant berth slewed round to hatchway to be reloaded-No. 2 bag is then discharged
in like manner, and berth again slewed round and so with No. 3 when the new draft
is weighed and the process repeats itself, there being always at least two bags in the
scale after first draft.

page_text: I EDWARD GRANDY, of Custom House Docks, Dublin, Ireland, Docks Manager 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:-
This invention has reference to improved apparatus for weighing corn in the bags
in which it has been shipped in an expeditious manner and in accordance with the
rules of the Liverpool Corn Trade Association, namely in drafts of three bags.
For this purpose a suitably constructed platform is erected on the deck,-in close
proximity to the hatchway of the vessel the cargo of which is to be weighed.
On this platform are erected scales, the construction and arrangement of which, as
also the mode of operating, will be readily understood by referring to the accom-
panying Drawings, in which Fig. 1. represents an elevation of the improved apparatus
complete.
Figs. 2 and 3 parts of the invention hereinafter more fully described.
A A is the platform which may be composed of any suitable wood and of any
suitable dimensions. On this platform is first fixed the Y shaped triangle iron shown
in Fig. 3, in the sockets of which are carried the three legs b, b, b, connected at the top
by a bolt c, which bolt also bears the shackle d. The scale beam e, is provided at
ends with the usual double hooked swivel gear and links, from which the scales are
suspended. The scale B, which carries the weights is of the ordinary construction,
while the scale C is novel in its arrangement, and construction, and constitutes the
essential feature of my invention as presently described.
The bottom of this scale is composed of a disc of oak and deal placed transversewise,
oak upwards-This disc is suspended from the beam swivel hook by a hooked centre
staunchion f, which bears, resting on a shoulder the three eyed plate g, to which are
attached three iron stayes h curved outwardly fixed at equal distances to the circum-
ference of the disc. These curved stayes are connected to a centre key plate i, placed
upon the centre staunchion, by three horizontal rods k. The scale is thus divided
into three cribs, which are numbered one, two and three, from right to left for the
purpose hereinafter described.
Placed across the platform at a distance of about two feet from the crib scale end
are two uprights 1, 1, carrying a horizontal cross bar upon which is fixed a piece of
gun barrel m, as represented in Fig. 2, the object of which will be obvious in the
description of the action of the apparatus which is as follows.
The crib scale having been loaded with three bags-standing on their ends-from
the hatchway the draft is weighed, when the bag from number one crib, is canted
over the cross bar m, and the vacant berth or crib is slewed round to hatchway to
be reloaded, number 2 bag is then removed from the crib in like manner and vacant
berth again slewed round to hatchway, and so with number three, when the new
draft is weighed and the process repeats itself, there being always at least two bags
in the crib scale after first draft.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1st. In the process of weighing corn, the method whereby I am enabled to weigh
three sacks at a time as required by the Liverpool Corn Trade Association sub-
stantially as herein described.
2nd. In the process of weighing corn the use and application of a crib scale,
constructed, arranged and operating in the manner substantially as indicated by the
scale C and its appendages in the accompanying Drawings.
3rd. In the process of weighing corn, the use and application of the crib scale C
in combination with the other parts of ordinary scales, and also in combination with
the horizontal bar m (Fig. 2.) in the manner substantially as herein specified and set
forth.
