COMPLETE SPECIFICATION.
Improvement in Toy Bridges.
J BENJAMIN PITT, 26 Stockpool Road Southville Bristol Engineer, 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:
Toy bridge erections suspension or otherwise and the various parts and materials
formed of the necessary size and shape for erecting the same, which parts are com-
posed of wood, metal, paper, flax, silk, and other necessary material for erecting a toy
bridge. The box for containing the several parts of the said material when not in use
is so made as to form the foundation of the said structure, the sides being removeable
it represents the space over which the bridge is to be erected. In this space I fasten
to the ends sides and bottom a suitable picture to represent any desired scenery or
waterfalls. The box is made with supports having grooves in them to receive the
moveable sides and to strengthen the foundation of the bridge when the sides are
removed. In the lower ends of the pillars are formed slots or grooves for fixing them
upon the ends of the box or foundation, crosspieces also having grooves formed in
them for fixing on the foundation between each pair of pillars, upon these crosspieces
grooves or projections are formed to receive one end of the approaches to the bridge,
to the other ends the chains or cables are secured and laid over the tops of the pillars
from which the floor of the bridge is suspended by graduated hooks or other sus-
pensions. Crossbars or girders are laid or fixed across the lower ends of each pair
of these suspensions to receive the floor of the bridge. To the sides of the floor and
approaches is fixed ornamental railing or material representing same. Caps are added
to the pillars to give the structure finish.
The following letters of reference will explain the accompanying drawings
figures 1, 2, & 3. Figure 1 is a section of the bridge, figure 2 is a vertical view of
box the dotted lines representing the removable sides figure 3 is a view of the planks
for forming the approaches to the bridge showing the slot for fixing same upon pro-
jections of crosspieces B. Letters C. D. E. have the same reference in figures 1 & 2.
D is the box or foundation with the sides removed. C the supports. E the ends
upon which the pillars and crosspieces are fixed, G the slot formed in the lower ends
of pillars, P the pillars. H the chains or cable. A the approaches. K the sus-
pensions. M the crossbearers upon which the floor of the bridge is laid. F the floor.
L the railing. O the caps.

page_text: The erection is performed in the following way.
First slide out the sides of the box and fix two pillars upon each end of the
foundation placing a crosspiece between each pair of pillars letting it rest upon the
foundation with the projections outside. Proceed to fix the ends of the approaches into
the said projections the other ends resting upon the ground. The chains or cables
are next laid over the tops of the pillars and the ends of same secured to the
approaches. The graduated hooks or suspensions are hung in pairs one upon each
chain or cable opposite each other, the shortest pair on either side of the centre pair
at equal distances to the end, the longest last, lay across the lower ends of each pair
of the suspensions the girders or bearers, upon which the floor is then laid. Finish is
given to the bridge by adding ornamental caps to the pillars.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed 1 declare that what I
claim is,
First. The suspension bridge erection and its several parts as substantially described
and set forth in the accompanying and foregoing specification.
Second. The box with removeable sides working in slots or grooves of supports to
the foundation of the bridge as substantially described and set forth in the accom-
panying specification.
Third. The graduated hooks or suspensions.
Fourth. A picture placed in the bottom and sides of foundation or box of the
bridge as described in the foregoing specification.
Fifth. The faſtening of the chains or cables to the approaches of the bridge.
