Combined with Coin Freed Mechanism.
I EDWARD JOHN COLBY of 1007 Opera House Block Chicago Illinois in the
United States of America 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 :-
By a machine constructed according to this invention a person can by standing up on
the arranged platform and inserting a single coin into the receptacle formed for it
test their bodily weight, strength, height, and lungs the whole of the said tests being
shown by suitable registering dials. Such a machine is designed to be stood in places
of public resort railway stations and the like.
To enable the construction and working of the machine to be properly understood
I will proceed to fully describe the same with aid of the accompanying drawings

mechanism. C, is the scale for the lifting machine; C, the scale for the weighing
machine C, is the height measuring scale. C³, the lung testing scale; C, the
lung testing tube; C³ the mouth piece of the same; the rack by which
it is suspended; C', is the head piece of the height measuring rod; C³ is
the rod proper, shaped as shown; C is a vertical branch of the same passing

page_text: through the aperture in the top of the box B, for a guide; Co is a side bar
secured to the base and box and within the lower portion of which reciprocates
the lifting rod C1, having the bandle C. D, is a rod which passes vertically into
the box from the scale or weight testing machine; it is secured above to a knife
edged pivot D', on the lever D, which lever has at one end a piston rod D³, the end
of which operates in the fixed dash pot D; said lever D2, is pivotted at D³ and to
its other end is secured the rod D, which is also pivotted and acts as a movable
fulcrum to the lever D; this lever carries at its outer extremity the weight D³ and
the arm 1, which operates in the dash pot D. At the opposite end of this lever D',
is pivotted the rack rod D" which engages the pinion D, on the shaft D, which
shaft is journalled in a suitable frame E3 and carries the pointer D¹³. On the
lever D, is pivotted at the same point as the rod Do, the rod D, which is
secured to one end of the walking beain lever D", which is pivotted on the shaft D18.
From the other end of this lever depends the arm D1, which engages the arm D20,
on the rock shaft D". On this same rock shaft is secured the weighted arm D
and the arm 123. Adjustably pivotted upon the lever De is the link D, to which is
pivotted the weighted rod 12, which passes into the pivoted pocket D2, and is
encompassed by the spiral spring D2, which bears respectively against the top of
the pocket and a collar D28, on the other end of the rod 128. This structure now
described and beginning with the rod described and indicated as the rod D,
constitutes the operating mechanism of the weighing machine together with a series
of lock freeing devices which is hereinafter described, are simultaneously operated
by the operation of the weighing machine so as when pressure is applied to the
weighing machine to retreat from and thus free all the register locks and when the
pressure is removed from the weighing machine to return to their position and
throw all the register locks into their normal positions so as to lock the registers.
We pass now to a description by indicating letters of the lifting machine. E is a
rod which passes upward into the case from the lifting levers and is secured to the
knife edged pivot block E on the lever E² to one end of which is pivoted the rod E³,
the end of which operates in the dash pot E. The lever E is pivoted at the
point E and to its other end is pivoted the rod E which rod is pivoted so as to act
as a movable fulcrum to a lever similar to D', one end of which is provided with a
weight similar to weight D8, the other with a rack rod similar to the rack rod D₁,
which meshes with the pinion E10, on the sleeve E", which rotates on the shaft D
The sleeve E, carries the pointer E. F, is a pipe connected with the lung testing
tube, and terminating above in the cylinder F, from which issues the piston rod F
upwardly held by the spiral spring F, which bears against the stop F', and the piston
head on the rod F. The rod F, terminates in the shoulder F, from which projects a
smaller rack bar F, which engages the pinion F, on the shaft F, which said shaft
carries the pointer F. The rod C, enters and passes along the side of the inner
portion of the box through the aperture in the top thereof, and through.the guido G.
It is counterbalanced by the chain G', which passes over the pulleys G², G³, and
supports the weight G. The rod C³, has a rack formed thereon or a series of apertures
and engages the toothed wheel G, on the shaft G, which carries the pinion G7,
which meshes with the gear wheel G³, on the shaft G, which shaft carries the
pinion Go, which pinion meshes with the rack bar G". This rack bar terminates in
an enlarged portion G, below and is provided with the weight G¹³, which rests upon
the shoulder formed by the enlarged portion G", and also rests against a sleeve on
the enlarged portion G1, which sleeve on one side is a rack bar Gis, and on the other
side a ratchet G. The rack G", engages the pinion G₁, on the shaft G, about
which is twined the rope G18, from which is suspended the weight G". H, H, are
ratchet wheels, respectively on the shaft 11, and the sleeve E". J, J, are arms on the
frame E, to each of which is pivoted a dog, having a spring arm J³, and a pawl J³,
which engages the teeth on the ratchet wheels H, H. On the other end of the
dog is pivoted the weighted elbow lever, on one end of which, is a weight and on
the other, a pawl and an arm J. This latter arm is engaged by the hook J, on the
rod M. K, is a pivoted stop having the points K', and K, and the pin. K³. The

page_text: end K, of this pivoted stop is engaged by the rod M. I, is a pivoted dog, having
the points L', L2, projecting end L³, and the hook L. The rods M, and M', are
secured to an arm M³, from the rock shaft M³. M', is a rod the end of which
operates in the dash pot M. Mo, is a weighted arm on the rock shaft M³, and M',
is a downwardly depending arm which engages the end L³, of the pivoted dog L.
M8, is another arm from the rock shaft M³, carrying the roller M, at its outer
end. N is a coin guide slotted at N¹, and terminating below in the coin
receptacle N2, with door N³, and lock arm N. The coin receptacle is cut away at
one side as at N³, to permit the roller M, to set in the path of the coin O. Ne, is a
rock shaft preferably with the weight N', thereon and having the arm N, the pivoted
coin pushing arm No, thereto attached. From the shaft Ne, projects the arm N10, to
which is pivoted the arm N, which latter projects through the front part of the case
and terminates in the push button N¹. P, is a cross rod to limit the motion of the
dog J, and is engaged by the spring portion J. R, is a rod on the shaft. D18, which
also limits the motion of the dog J past its perpendicular. In the frame E's, are set
between the arms S, S, the pulleys S', S', which serve to keep the rack rods D, and
the one similar thereto in position against their respective pinions. T, is a block
adjustably secured upon the lever E2. Secured to it is the weighted rod T', which
passes into the pivoted pocket. T2, and is encompassed by the spring T3, which
bears against the top of the pocket, and a nut on the end of the rod T. U, is the
platform on which the person stands who desires to use the machine, and U¹, is an
arm projecting in the usual manner from the supports on which such platform rests,
and connecting with the rod D. V, is a rock shaft operating from the lifting handles,
and having the arm V', which connects with the rod E.
The use and operation of my invention, are as follows ;-
The machine constructed substantially as shown in figure 1, is set up in a place where
it is designed to be used, as for instance, in a place of public resort. Briefly the operation
of the machine is such, that when the person using the same steps between the rails C10,
and onto the weighting platform, his weight operates the scale mechanism or weighing
apparatus but does not cause any of the registers to move.
The motion or action of the weighing apparatus however, throws back the several
rods hereinafter referred to, and thus frees all the locks of the registering devices, so
that if a coin be thereupon introduced, all of the locks will be released, and and all of
the registering devices placed in position to be operated, so that the person standing
upon the platform may first see his weight registered; by lifting upon the handles he
will see his lifting power registered; by blowing in the lung testing tube he will see
the measure of the capicity of his lungs; and by drawing down the height measuring
rod until the end rests upon his head he will see the registration of his exact
height. None of these operations can be performed by any person except the one
standing upon the platform, except, the lung testing, and this when once used is
automatically locked until another coin has been introduced. When the user steps
off of the platform U, the action is such as to reset all of the locks and leave them in
such position that the registers can not operate. If now a person steps upon the
weighing platform the structure is such that the pressure is applied to the rod D, the
lever D², is turned on its pivot, the rod De, is forced upwardly and the lever D², turns
upon the pivotal point of its connection with the rack rod D". The latter it is
evident can not move upwardly, as the pinion with which it meshes is locked upon
the sleeve E. The upward motion of the lever D7, carries with it the rod 11,
tilts the walking beam lever D", forces downward the rod D1, and thus rocks the
rock shaft 1)", in its bearings against the counter weight D2, so as to bring the arm R,
on the rock shaft D18, out of position to interfere with the end J2, of the dog;
the arm D, out of position to interfere with the pin K³, and the arm D23, out of
position to interfere with the hook L, so that so long as the person using the
apparatus remains upon the platform, and so long as the rock shaft D18, is thus
turned in its bearings, any or all of the lock devices are freed, and in a position -
where they may be released. If now a coin be introduced into the coin chute N, it will

page_text: 1
stop when it reaches the roller M, ani. if then pressure be applied to the push
button N, thence through the ro: N, to the arm N10, to rock the rock shaft No,
thus moving the arm N, and the coin push arm N2; by these means the coin will be
forced through its chute N, thus forcing outwardly the roller M, and the arm M³, to
which it is attached; moving this arm Ms, outwardly, causes the rock shaft M³, to
turn in its bearings, and the arm, and thus the several locking devices are released
as will now be described. The rocking of the shaft M³, causes the arm M7, to strike
the end L³, of the rocking stop or dog L. and thus lift its teeth from the rack G³, and
thus the rack will be free to vertically reciprocate. In like manner the operation of
the rock shaft M³, forces the arm M², downwardly, thus carrying down the arm M',
and throwing the pivoted stop K, into the released position. The same motion of the
arm M², carries with it the arm M, and thus the two hooks J, which cause the respective
dogs and their respective parts to be straightened out whereby the pawls J³, J³, are
freed from the raichet wheels H. By this latter motion the registering apparatus
connected with the weight testing machine or scale is free to operate, and the
weight D, on the lever D7, will cause the latter to swing about this pivotal
connection of the rod D, and thus throw upwardly the rack rod D", and operate the
shaft or sleeve to register the weight of the person on the dial.
if now the person desires to test his strength he has only to pull upwardly on the
handles, and in a similar manner will the lever E7, and the rack rod E2, operate to
cause the pointer on the proper dial to indicate the amount which the person testing
himself has lifted.
It will be observed that as indicated in figures 3 and 4, the locking parts and
registering operating parts both weighing and lifting machines are substantially
the same and placed directly one behind the other, so that both are not entirely
visible in a view like that shown in figure 2.
If now the person desires to test his lungs, he does so by blowing into the tube, the
stop as is above described, being out of the way of the shoulder F³, so that the
piston rod F, can descend from the cylinder F, turning the pointer so as to indicate
the strength of the lungs, but while the rod I, passes downwardly the shoulder F³,
will engage the upper point of the pivoted stop K, and knock such stop down into the
position shown in figure 2, and when the rod F, returns to its position the stop will
be ready to engage it and prevent its being used again. To test the height, the
pivoted dog or stop L, having been thrown out, it is only necessary to draw down
the rod until its end or the head piece rests upon the head; by so doing the
gears and
pinions G, G, GB, and G10, are so operated as to cause the rack rod G1, to descend.
To prevent injury to the machine from abrupt action, the weight G¹³, encompasses the
rod G, resting upon the shoulder of the lower portion of such rod, and upon the
sleeve which bears the rack and ratchet, sudden downward motion of the rod G",
will therefore produce no injury, as the weight G13, can freely move upon the
rod G, and permit the sleeve to rise with it also, but the weight of the part G¹³,
is such as to counterbalance the weight of G, and cause the parts to resume their
proper positions where upon the height will be indicated.
I am aware of the Specification of Letters Patent No. 16,433 of 1884 granted
to Percival Everitt and also of the Specification of Letters Patent. No. 12,576 of 1885
granted to Robert William Page, and I wish it to be understood that I do not claim
anything described and clained in either of the said Specifications.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed; I declare that what I
claim is :
1. In a testing machine as described, the combination of a series of testing devices.
and registering apparatuses normally locked with freeing mechanism for said locks
operated by the operation of the first testing device.
2. In a testing machine as described the combination of a series of testing devices

bears against the top of the pocket, and a nut on the end of the rod T. Ú, is the
platform on which the person stands who desires to use the machine, and U¹, is an
arm projecting in the usual manner from the supports on which such platform rests,
and connecting with the rod D. V, is a rock shaft operating from the lifting handles,
and having the arm V', which connects with the rod E.
The use and operation of my invention, are as follows;-
The machine constructed substantially as shown in figure 1, is set up in a place where
it is designed to be used, as for instance, in a place of public resort. Briefly, the operation
of the machine is such, that when the person using the same steps between the rails C¹º,
and onto the weighing platform, his weight operates the scale mechanism or weighing
apparatus but does not cause any of the registers to move.
The motion or action of the weighing apparatus however, throws back the several
rods hereinafter referred to, and thus frees all the locks of the registering devices, so
that if a coin be thereupon introduced, all of the locks will be released, and and all of
the registering devices placed in position to be operated, so that the person standing
upon the platform may first see his weight registered; by lifting upon the handles he
will see his lifting power registered; by blowing in the lung testing tube he will see
the measure of the capacity of his lungs; and by drawing down the height measuring
rod until the end rests upon his head he will see the registration of his exact
height. None of these operations can be performed by any person except the one
standing upon the platform, except, the lung testing, and this when once used is
automatically locked until another coin has been introduced. When the user steps
off of the platform U, the action is such as to reset all of the locks and leave them in
such position that the registers can not operate. If now a person steps upon the
weighing platform the structure is such that the pressure is applied to the rod D, the
lever D, is turned on its pivot, the rod De, is forced upwardly and the lever D', turns
upon the pivotal point of its connection with the rack rod D". The latter it is
evident can not move upwardly, as the pinion with which it meshes is locked. upon
the sleeve E. The upward motion of the lever D', carries with it the rod D₁,
tilts the walking beam lever D1, forces downward the rod D1, and thus rocks the
rock shaft D2, in its bearings against the counter weight D, so as to bring the arm R,
on the rock shaft 118, out of position to interfere with the end J2, of the dog ;
the arm Do, out of position to interfere with the pin K³, and the arm D2 out of
position to interfere with the hook L, so that so long as the person using the
apparatus remains upon the platform, and so long as the rock shaft 11, is thus
turned in its bearings, any or all of the lock devices are freed, and in a position
where they may be released. If now a coin be introduced into the coin chute N, it will
stop when it reaches, the roller M, and if then pressure be applied to the push

page_text: button N, thence through the rod N", to the arm N10, to rock the rock shaft No,
thus moving the arm N, and the coin push arm N'; by these means the coin will be
forced through its chute N, thus forcing outwardly the roller M, and the arm Ms, to
which it is attached; moving this arm M³, outwardly, causes the rock shaft M³, to
turn in its bearings, and the arm, and thus the several locking devices are released
as will now be described. The rocking of the shaft M³, causes the arm M7, to strike
the end L³, of the rocking stop or dog L, and thus lift its teeth from the rack G15, and
thus the rack will be free to vertically reciprocate. In like manner the operation of
the rock shaft M³, forces the arm M2, downwardly, thus carrying down the arm M',
and throwing the pivoted stop K, into the released position. The same motion of the
arm M², carries with it the arm M, and thus the two hooks J, which cause the respective
dogs and their respective parts to be straightened out whereby the pawls J³, J³, are
freed from the ratchet wheels H. By this latter motion the registering apparatus
connected with the weight testing machine or scale is free to operate, and the
weight D³, on the lever D', will cause the latter to swing about this pivotal
connection of the rod De, and thus throw upwardly the rack rod D", and operate the
shalt or sleeve to register the weight of the person on the dial.
If now the person desires to test his strength he has only to pull upwardly on the
handles, and in a similar manner will the lever E', and the rack rod E, operate to
cause the pointer on the proper dial to indicate the amount which the person testing
himself has lifted.
It will be observed that as indicated in figures 3 and 4, the locking parts and
registering operating parts both weighing and lifting machines are substantially
the same and placed directly one behind the other, so that both are not entirely
visible in a view like that shown in figure 2.
If now the person desires to test his lungs, he does so by blowing into the tube, the
stop as is above described, being out of the way of the shoulder F, so that the
piston rod F2, can descend from the cylinder F, turning the pointer so as to indicate
the strength of the lungs, but while the rod Fe, passes downwardly the shoulder F,
will engage the upper point of the pivoted stop K, and knock such stop down into the
position shown in figure 2, and when the rod F6, returns to its position the stop will
be ready to engage it and prevent its being used again. To test the height, the
pivoted dog or stop L, having been thrown out, it is only necessary to draw down
the rod until its end or the head piece rests upon the head; by so doing the gears and
pinions G³, G7, G8, and G10, are so operated as to cause the rack rod G", to descend.
To prevent injury to the machine from abrupt action, the weight G¹³, encompasses the
rod G₁, resting upon the shoulder of the lower portion of such rod, and upon the
sleeve which bears the rack and ratchet, sudden downward motion of the rod G",
will therefore produce no injury, as the weight G₁, can freely move upon
rod G, and permit. the sleeve to rise with it also, but the weight of the part G¹³,
is such as to counterbalance the weight of G, and cause the parts to resume their
proper positions where upon the height will be indicated.
