COMPLETE SPECIFICATION.
An Improved Apparatus for Carrying Plate-glass.
JOHN JAMES SPEAR 70 Crosswell Street Landport Portsmouth Hants Glass
Merchant 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 :-
It is constructed of wood & iron, the flat surface being covered with felt so as to
form a soft bed on which plate rests. Wood buttons support the glass when putting
on & taking off.
The apparatus will lift on to two movable hooks as shown secured to conveyance,
which will then be easily raised horizontally when two rollers take the back
weight & run themselves clear on the van. Felt on either end for the first three
bars is thicker than it is in the middle to allow for viberation downwards. The
hooks acts as pivots on which iron bars work. Back struts form braces as the foot
of apparatus rest on pavement. Wheels of van in channel so that the whole is
perfectly safe while glass is being put on or off. Handles are for raising up &
down &c.
The apparatus is made of wood & iron and made in three sizes namely. First size
eight feet by five feet thickness of wood two inches by two inches. Second size
nine feet by seven feet, thickness of wood two & half inches by two inches. Third
size ten feet by eight feet, thickness of wood three inches by two inches. All the
face of apparatus will be covered with felt. Three bars at either end the felt will be
three eights of an inch thick and the three bars in centre will be about a quarter
inch thick. The reason why felt is thinner in the middle is to allow of vibiration
downwards for safe transit. The possition of apparatus when putting on plate glass
will be slanting, with the bottom as shown in drawing resting upon the side walk.
And iron rod marked E will be the height at which it will rest against the van to
which is attached the iron hooks F to take the 17 iron rod E which forms the
bearing while it is moved up or down at will, B are the strutts which will move
backward & rest upon two boards attached to the van for that purpose and keep
apparatus in safe possition while glass is being put on or while taking it off. O are
the buttons (iron) which secures the strutts while the apparatus is being lowered
flat upon the van. D are the iron rollers which take the back weight and allows
the apparatus to run smoothly into its right possition on the van (& saves any risk
through lifting at corners) as the front has only to be lifted slightly & it will pass
easily into possition. G are iron handles by which it is moved up or down as the case
may be & also to move it from place to place. A are wood buttons made of har
wood and secured by iron bolts so that they can be turned at will (with a nut on the

page_text: inside to make a sufficient room so that the buttons can turn easily on the iron bolts
& when not in use to be turned back again. The buttons support the glass, while it
is being lowered on the van (flat).
Having now particularly described & 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. A safe and easy mode of carrying plate glass flat.
2nd. That it can be used in very awkward possitions such as when a floor is
lower than window sash frame. The apparatus can be carried through the opening
with plate glass on & lowered flat then raised, tucking it between floor & sash frame;
plate glass lifted off, apparatus put outside of window, and in with the glass.
3rd. It will save as is now done the risk of turning plates on the corners from
width to height, by turning the apparatus on the van, the plate glass will be in its
right possition thereby saving the great risk of turning plate glass on the naked
corner, as is now the practice."
