Improvements in Toys or Means or Apparatus for Use in Teaching
Mechanical Construction, or for Recreation.
I THEODORE BIRNBAUM of Wick Lane Rubber Works, Bow, in the County of
Middlesex, India Rubber Manufacturer do hereby declare the nature of this invention.
to be as follows :--
This invention relates to toys or means or apparatus for use in teaching mechanical
construction or for recreation.
In carrying out my invention I employ a number of rods of suitable form in
cross section; but I prefer to use rods of wood, of a simple circle, or hexagonal in
cross section; in fact much the shape of ordinary cedar pencil answers well.
With these rods I employ a suitable number of double clips, each clip being shaped
from metal plate into a form adapted to receive a rod and hold it within its trough like.
bed, the sides of the short trough forming springs. These clips have a flat base or mid-
section and two such mid-sections for each double clip are brought back to back and
connected together by a rivet, which acts also as a hinge allowing the one clip part to
turn relatively to its twin part as may be required in assembling a number of these
rods together in forming a trestle-bridge, a bridge-truss, a military or other model..
bridge, or other construction for instruction or for purposes of recreation.
Very elaborate and beautiful designs in mechanical construction can be carried
out, or engineering problems demonstrated by the aid of the present invention whilst
when not required for use the parts can be stowed away within an extremely small
compass.

Mechanical Construction, or for Recreation.
I THEODORE BIRNBAUM of Wick Lane Rubber Works, Bow, in the County of
Middlesex, India Rubber Manufacturer 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 relates to toys or means or apparatus for use in teaching mechanical
construction or for recreation.
In carrying out my invention I employ a number of rods of suitable form in cross.
section, but I prefer to use hollow or solid rods or cylinders of wood or metal of a
simple circle, or hexagonal in cross section; in fact much the shape of an ordinary
cedar pencil answers well. With these rods I employ a suitable number of double.

DESCRIPTION OF THE DRAWINGS.
Fig. 1 shows an example of a number of rods assembled and held in position by
double clips according to my present invention, and,
Fig. 2 is a side view of the same.
Fig. 3 shows the double clip to a larger scale and Fig. 4 is a side view of the same
taken at right angles to Fig. 3.
Figs. 5 and 6 show one half part of the clip separately by front view and side view
respectively.
Fig. 7 is a plan view and Fig. 8 a perspective view of the clip.
Figs. 9 and 10 show examples of construction such as may be carried out by the
aid of the present invention.
The clips a have a flat base or mid-section b and two such mid-sections for each
double clip are brought back to back and connected together by a rivet c which acts
also as a hinge allowing the ene clip part to turn relatively to its twin part as may
be required in assembling a number of the rods d together in forming a trestle-bridge,
a bridge truss, a military or other model bridge, or other construction for instruction
or for purposes of recreation.
Very elaborate and beautiful designs in mechanical construction can be carried out,
or engineering problems demonstrated by the aid of the present invention whilst
when not required for use the parts can be stowed away within an extremely small
compass.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I claim is :-
1. The arrangement or combination of parts of apparatus for use in teaching
elementary mechanical construction or as a toy for recreation, as set forth.
2. The construction and use of the double clip or holder indicated more particularly
in Figs. 3 to 8 and having the one half or each single clip centred upon the other hal
or single clip, as and for the purpose herein before set forth.
