An Improved Platform, Truck, or Trolley for Moving Heavy
Articles, such as Desks, Planos, Harmoniums in Schools, Bales
and Packages in Warehouses and Manufactories, and Luggage
at Railway Stations.
JOHN CUMPSTEY 13 St. Paul's Street Blackburn England, Caretaker, do hereby
declare the nature of this invention to be as follows:-
The invention consists of a platform mounted upon casters. The platform may vary
in length and breadth according to the kind of work to which it is applied. For
schools suitable lengths would be from six to nine feet by one foot; for pianos and
harmoniums &c. four and a half feet by two feet; for warehouses the length and
breadth would vary according to the size of the bale or package to be removed. No
handle is necessary; the article when placed upon the platform is simply pushed in
the direction required.
The caster consists of an upper circular plate Fig. I II III a, with bevelled rim b b.
This plate is fixed to the platform. The center of it is sunk, pierced for center pin c
for pivot, and drilled for affixing screws, d. d. Fig. I. The lower parts of the caster
consist of the following:
.
First, a semi-circular disc e. e. e. Fig. I. II. III. revolving round axis c
Fig. I. II. III. The disc revolves upon the upper rim a and upon the bevelled rim b
by means of bevelled rollers f. f. Fig. II. III.
Secondly, a roller g Fig I. II. III. revolving on pin h h. Fig. I. II. III.
What is claimed for this invention is that by means of a platform mounted upon the
casters, Fig. IV., a great saving of labour is effected, as heavy weights may be pushed
with the utmost ease in any direction. The platform readily adjusts itself to the line of
force and runs so easily that great weights can rapidly be removed by one man.
It is especially adapted for removing desks, pianos, harmoniums, &c., in Schools ;
bales and packages in warehouses and manufactories; and for the removal of luggage
at railway-stations, &c.

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 :-
The invention consists of a platform mounted upon casters. The platform may vary
in length and breadth, according to the kind of work to which it is applied, e.g. for
school-desks, suitable lengths would be from 6 to 9 ft., and breadth, one foot; for
pianos, harmoniums &c 4 ft. by 2 ft.; for warehouses, the length and breadth would
vary according to the size of the bale or package to be moved; and for pictures,
according to size. No handle is necessary; the article, when placed upon the platform
