1. EDWARD BARRY of 75 St. Donatts Road, New Cross, in the county of Kent,
Sergeant Major Instructor in the 2nd Middlesex Artillery Volunteer Corps, do hereby
declare the nature of this invention to be as follows :-
:-
My improvement relates to an apparatus for teaching applied mechanics, and
consists in mounting all the different mechanisms in the form of working models
on one frame, where they can best be shown in action, in such a manner that each
or all of them can be readily detached therefrom when it is needed for separate and
distinct demonstration.
:-
The frame is preferably made of a rectangular form, consisting of four uprights,
and four long, and four short transoms of wood or metal.
On the frame are detachably mounted the following -A board forming a horizontal
plane. A board forming an inclined plane and adapted to be adjusted to vary the
inclination by means of a rack and pinion. Two parallel metal rails on which work
a traversing crane. A jib crane revolving on a centre bolt and wheels. A pair of
shear legs having a lifting tackle. A warf crane operated by a windlass.
A crab.
A capstan. A pile driver. A lever arranged to show the three orders, with
varying leverages. A lever working on a knife edge and fitted to a moveable beam.
A frame for testing metals. A screw & lever. Snatch blocks. A wedge with
block of wood adapted to illustrate its action. An eccentric sphere to illustrate the
centre of gravity of a body. A double cone and inclined plane. A. measuring rod..
Standard weights and measures. Plumb and spirit level. Sliding battens to
demonstrate efficiency of lubricants. Various examples of wheels and axles, of guide
pulleys, of rollers and of buckets and boxes.
All these various mechanisms, and parts thereof are so arranged that their use can
be easily and readily demonstrated either alone or in conjunction with each or any
of the other parts.

page_text: A suitable box is provided into which the whole apparatus can be conveniently
packed.

Improvements in Apparatus for Teaching Applied Mechanics.
I, EDWARD BARRY, of 75 St. Donatts Road, New Cross, in the County of Kent,
Sergeant Major Instructor in the 2nd Middlesex Artillery Volunteer Corps, 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:-
:-
My improvement relates to an apparatus for teaching applied mechanics, and
consists in mounting all the different mechanisms in the form of working models on
one frame, where they can best be shown in action, in such a manner that each or all of
them can be readily detached therefrom when it is needed for separate and distinct
demonstration.
In order that my invention may be fully understood 1 hereto append a drawing
illustrating my apparatus. Referring to this drawing, the frame is preferably made
of a rectangular form, consisting of four uprights and four long and four short
transoms of wood or metal. On the frame are detachably, mounted in the manner
shown by the accompanying drawing, or in any other suitable manner, models illustrating
the following. mechanisms. A board A forming a platform in a horizontal plane.
A board B forming a platform in an inclined plane, and adapted to be adjusted to
vary the inclination by means of a rack and pinion. Two parallel metal rails c. c on
which travels a traversing crane C fitted with a crab or winch c¹. A jib or wharf
crane D revolving on a centre bolt or wheels, the load of which is raised by a
windlass d. A pair of shear legs E having a lifting tackle e. A derrick crane F
mounted on a movable platform F¹ supported by a stay F, the load being raised by
a windlass f. The windlass f¹ serves to alter the angle of the jib. A windlass
A capstan G. A pile driver H, with its pile which is inserted in the iron
cylinder L when filled with sand to demonstrate the action of driving a pile. A
lever J, arranged to show the three orders with varying leverages. This lever with
.

page_text: the aid of the hook or clip ; the weights S' and one or more slips of wood from the
platform a may be used for testing the deflection and strength of metals. A lever K
working on a knife edge and fitted to a moveable beam. Rollers L, iron cylinder L¹,
& trolley L running on rails or strips of wood b. b on the board inclined plane B
for measuring friction. A screw and lever M. Several forms of tackles NN,
formed by cords being rove through blocks n. n etc. A snatch block n¹. A
wedge O, mallet ol with blocks of wood O¹ split down the centre and held together
by means of elastic bands o o to illustrate its action. Two rectangular blocks P P,
to illustrate the centre of gravity of a body. An eccentric sphere P¹ and
concentric sphere P also to illustrate the centre of gravity of a hody, and the
deflection of a body in motion to its heaviest side. A double cone Q and an inclined
plane Q. A plumb and spirit level R. A measure S, and weights S₁ S¹. Clamping
screws TT, and various examples of skips U. A compound wheel and axle V with
pulley v. Wheel and axle combined with screw W. Several examples of grooved
wheels X and axles X'. Pulleys Y and guide pulleys Y¹. On the platform A several
battens of wood a a etc. are placed, covered on their undersides with various
lubricants for the purpose of measuring friction. A measuring rod is also provided,
but which is not shown in the drawing.
All these various mechanisms and parts thereof are so arranged that their use can
be easily and readily demonstrated either alone or in conjunction with each or any
of the other parts. A suitable box is provided into which the whole apparatus can
be conveniently packed.
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 :-
1st. An apparatus for teaching applied mechanics, constructed, arranged, and
operating as set forth.
2nd. In an apparatus for teaching applied mechanics, the combination of the
several parts and mechanisms as hereinbefore described and illustrated in the
accompanying drawing.
