PROVISIONAL SPECIFICATION.
Improvements in Muscular-power Testing Machines.
I, NORMAN WILLIS RUSS, of 21, De Crespigny Park, Denmark Hill, in the
County of Surrey, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention has for object to provide a machine for indicating or disclosing the
lifting power exerted by the arm of a person when extended, upon the introduction of a
coin, token or the like into the machine or apparatus.
In a suitable arrangement for carrying out my invention 1 employ two tubes
telescoping one into the other and containing a steel spring adapted to be compressed
or extended as the tubes are moved relatively to each other by the hand of the person
making use of the apparatus. In order that the relative movement of the tubes may
be indicated or disclosed when a coin or the like is introduced into the apparatus I
provide suitable indicating mechanism, a rod or the like connected with which extends
into proximity to a shelf or platform onto which the coins introduced into the
apparatus fall and which is adapted to move with the movable parts of the apparatus.
In the said shelf or platform is an aperture through which the adjacent rod or the
like passes when no coin is upon the shelf or platform so that no motion is then
imparted to the indicating mechanism.
In connection with the said shelf or platform is a ledge which retains the coin for
a time but allows it to slide when the parts have been moved a certain extent.
Instead of employing a steel spring I may employ a fluid or other spring arranged
in a suitable manner in connection with indicating mechanism.

COMPLETE SPECIFICATION.
Improvements in Muscular-power Testing Machines.
I, NORMAN WILLIS RUSS, of 21, De Crespigny Park, Denmark Hill, in the County
of Surrey, 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
--
My invention has for object to provide a machine for indicating or disclosing
the lifting power exerted by the extended arin of a person using the machine upon
the introduction of a coin, token or the like.
In a suitable arrangement for carrying out my invention I employ two tubes
telescoping or sliding one within the other, and containing spring adapted to be
compressed or extended as the tubes are moved relatively to each other by the hand
of the person making use of the apparatus. In order that the relative movement of
the tubes may be indicated or disclosed when a coin or the like is introduced into the
apparatus I provide suitable indicating mechanism, a rod, bar or the like connected
with which extends into proximity to a shelf or platform onto which the coins intro-
duced into the apparatus fall and which is adapted to move with the movable parts of
the apparatus. In the said shelf or platform is an aperture through which the rod,
bar or the like passes when no coin is upon the shelf or platform, so that no motion is
then imparted to the indicating mechanism.
In connection with the said shelf or platform is a projection which retains the
coin for a time but allows it to slide when the parts have been moved a certain
axtant

page_text: To enable my invention to be fully understood
reference to the accompanying drawing, in which:-
will describe the same with
Figure 1 is a sectional front elevation of a coin-freed muscular power testing machine
constructed according to my invention:
Figure 2 is a vertical section on the line a Figure 1; and,
Figure 3 is a horizontal section on the line y y Figure 1:
Figures 4 and 5 are an elevation and section of a detail hereinafter described.

a indicates the base or foundation which is provided with a drawer 6 for the
reception of coins introduced into the apparatus, and c is a tube, serving as a pillar or
standard, secured at its lower end to the base a and having upon its upper end the
head d, which carries the dial e and the indicating mechanism hereinafter described.
fis a second tube sliding upon the tube c, and g is a spiral spring connected at one
end to a pin extending diametrically across the tube and at the other end to a
fixed pin in the base or foundation, the said spring normally tonding to maintain the
tube fin its lowest position upon the tube c and, while the said tubo fis raised, being
more or loss distended, according to the amount of movement imparted to the said
tube. Slots are formed through the tube c for the passage of the pin / when the
tube f is moved.
k¹
k is the rod or bar serving to communicate the movement of the tube f to the
indicating mechanism, which rod or bar at its upper end is provided with rack-teeth/
in engagement with a pinion m on an arbor n carrying the hand or pointer o of the
indicating mechanism, which hand or pointer works over the dial e. The said bar at
its lower end is provided with a projection working in connection with the shelf for
a purpose hereinafter described, and slides in a guide p secured in the tube c, and in a
guide y formed integral with a bracket secured to the back of the dial e and carrying
one end of the arbor n. The bracket also carries a springs which serves to main-
tain the bar in the guide 7 and also to. exert sufficient friction upon the said
bar to prevent it from falling, from any position in which it may be placed, owing
to gravity.

is the shelf or platform onto which coins introduced into the apparatus through
the slot u fall, and is the aperture therein. This shelf is carried by a tube v con-
nected with the tube f by the pin h so as to move therewith, the said tube v being
flattened upon one side, as shewn at Figure 3, so as to allow the passage of the coin
through the space, between the flattened surface v and the tubo c, to the drawer b.
The tubo.v is also provided with an extension above the shelf t, which extension
serves as a shoot to direct coins, introduced into it through the slot w' and the slot w
in the tube c, onto the shelf t. w is a bar for preventing coins passed through the
slot w from falling across the shoot and stopping it.
With this construction it will be obvious that, when a coin is introduced into the
apparatus, it falls through the extension or shoot w onto the shelf lying on its flat
surface beneath the end of the bark and being prevented from slipping off the said
shelf by the projection ¹ upon the end of the said bar. If now the tube f is raised
against the tension of the spring g the tube vand the shelf t with the coin thercon will
also be raised, whereby the coin, by pressing against the end of the bar k, will lift the
said bar a corresponding distance and so cause the movement of the hand upon the dial, 4
thereby indicating the power exertod: when the tubo fis released the shelf moves
away from the end of the bar k, so that the coin being unsupported by the projection k¹
slides from the said shelf into the money drawer. The hand is returned to zero upon
the dial and consequently also the bar returned to its normal position, by means of a
knob z on the end of the arbor n projecting through the covering glass of the dial, and
serving to rotate the said arbor.
Upon the bar & is a lateral projection which, when the said bar is raised after the
introduction of a coin, passes in front of the slot u and so prevents the introduction of
another coin until the hand or pointer returns to zero. v is a slot in the tubo v
through which the said projection passes.
Instead of using a spring of the kind hereinbefore described it is to be understood
any other suitable forin of spring may be used.
