Year: 1897

I, JAMES FERRIER, of 105, High Street, Dunfermline, in the County of Fife, .
Music Seller and Pianoforte Dealer, do hereby declare the nature of this inven-
tion to be as follows:--
This invention has for its object to provide a simple and inexpensive bogie,
trolley or like support for a piano and which is especially adapted for use in
schools in which pianos are frequently moved about in class rooms or from one
room to another.
The improved bogie or piano support is composed of a flat wooden or other
frame approximating in form to the under side of the piano to which it is applied,
the said frame being fitted with two wheels on fixed axes at either end and with
two central wheels on pivots. The wheels at the mid part of the frame are of
larger diameter or are lower than those at the ends so that the piano when placed
or secured upon the frame may slightly rock, and they are so pivoted that they
will turn in any line to suit the direction in which the piano may be removed.
When the piano is moved endwise it rests on either pair of the end wheels and on
the central wheels; but when moved backwards or forwards or at any angle the
piano is balanced on the central pivoted wheels and it is then easily run over the
floor. When placed in any position for use the piano is steadied by inserting
wedges under the end of the frame or under the smaller wheels.

Improved Bogie or Trolley for Pianos.
I. JAMES FERRIER, of 105, High Street, Dunfermline, in the County of Fife,
Music Seller and Pianoforte Dealer, do hereby declare the nature of this inven-
tion 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 for its object to provide a simple and inexpensive bogie,
trolley or like support for a piano and which is especially adapted for use in
schools in which pianos are frequently moved about in class rooms or from one.
room to another.

page_text: The improved bogie or piano support, which is illustrated by the accompanying
drawings, Figure 1 being a longitudinal elevation, and Figure 2 a plan thereof,
is composed of a flat wooden or other frame A approximating in form to the under
side of the piano to which it is applied, the said frame being fitted with two
wheels B on fixed axes at either end and with two central wheels C pivoted on a
fixed axle as shewn. The wheels C at the mid part of the frame A are of larger
diameter or are lower than those B at the ends so that the piano when placed or
secured upon the frame may slightly rock, and these wheels C are so pivoted or
arranged that they will turn to suit the direction in which it is desired to move
the piano. When the piano is moved endwise it rests on either pair of the end
wheels B and on the central wheels C; but when it is required to be swung round
or turned in any desired direction it is balanced on the central pivoted wheels C
and it is then easily run over the floor. When placed in any position for use the
piano is steadied by inserting wedges under the ends of the frame or under the
smaller wheels. Or as shewn one set of wheels B may have their axle secured
on a hinged portion A¹ of the frame A, in order that the end wheels B may be
brought to bear upon the floor as shewn in dotted lines, Figure 1, when the piano
is at rest, rocking movement being prevented by a spring pressing on the lower
or hinged portion of the frame. When it is desired to move the piano this hinged
portion is hooked up by catches on the end of the frame.
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:-
The improved bogie, trolley. or support for pianos constructed substantially as
and for the purpose set forth.
