1886; in Belgium, No. 7 6,243, dated February- 5, 1887; in Germany, No. 40,258, dated January 25, 1887; in Italy, Vol. XXI, No. 21,369, Vol. XLII, No. 431, dated March 31, 1887, and in Victoria, No. 5,136, dated J une 17, 1887,) of which the following is a specification.

This invention relates to the construction of a machine adapted for testing the muscular power exerted by a person in the act of pulling in a horizontal or nearly horizontal direction, and while in a sitting or reclining position, the object of the invention being to provide a machine which will allow of bringing into play muscles which cannot be brought into play by the use of known machines. For this purpose I provide a seat, which may advantageously be a sliding seatsuch as is used in rowing boatsin connection with a foot rest or rests or stretcher or stretchers, which may be adjustable. The handle or handles of the machine is or are arranged in the line of the draft, so as to allow of obtaining a direct pull. These handles, which are adjustable, are suitably connected by means of rods, levers, or otherwise to a spring or weight, which forms the resistance ,the said handles being also connected to an indicating apparatus; or an arrangement may be added whereby the indication of the power exerted is only disclosed on the application of acoin or token to be placed in the apparatus, in a manner similar to that described in the specification of R. W. Pages application, Serial No. 216,665, filed October 19, 1886.

In order'to enable my invention to be fully understood,I will proceed to describe the same by reference to the accompanying drawings, in which- Figure 1 represents a front elevation of a machine for testing muscular power, constructed according to my invention and adapted to indicate the power exerted only on the insertion in the apparatus of a coin or token. Fig. 2 is a side elevation, partly in section, and Fig. 3 a sectional plan, of the same. Fig. at is a front elevation,drawn to a larger scale, of part of the apparatus, a portion of the casing being removed in order to show the indicating mechanism. Fig. 5 is a horizontal section on line 5 5 of Fig. 4, and Fig. 6 is a vertical section on line 6 6 of Fig. 4.

Similar letters in all the figures represent the same or similar parts.

0 represents the seat on which the person testing his muscular power sits, the said seat being shown arranged to slide on a pedestal or stand, I), in a similar manner to the sliding seat of a rowing-boat.

c is a platform on which the pedestal or stand 6, as well as the muscular-power testing and indicating mechanism, is mounted.

d d are the foot-rests or stretchers.

e e are the handles of the machine, which are arranged in the line of the draft, as shown clearly in Figs. 2 and 3, so as to allow of obtaining a direct pull. The handles 6 are carried by a screw-threaded rod, f, working in the hollow rod or tube 9, which slides in a cylinder, 71., fixed to the pillar or standard i of the machine. threaded rod the handles 6 can be adjusted to suit the person who grasps them in order to test his muscularpower.

j is the spring, to which the handles 6 are connected by means of the rod or tube 9, the said spring forming the resistance to the power applied to the handles 6. A flange,7c,on the inner, end of the rod or tube {1 forms a kind of piston, between which and the cap or cover Z of the cylinder h the spring j is compressed.

To the inner end of the rod or tube 9 is attached a cord, m, passing about or under a pulley, n, and up through the pillar or stand ard i into the casing 0, containing the indicating mechanism shown in Figs. 4, 5, and 6. The

By means of this screw-' cord m there passes around and is attached to 5 over a dial, t, placed outside the casing o of I00 the apparatus and serving to indicate the said muscular power. Pinions u and u are fixed on the sleeve q and arbor g, respectively, and gear into quadrants u and v on arms and w, pivoted at wand 11:, and provided with con nterweights 3/ and y. The arm w carries the receptacle or bucket z for the coin a. (Shown in dotted lines at Fig. 4.) The bucket z has an open top, and is normally situated immediately below a chute, 1), extending from a slit, 0, in the casing 0 of the apparatus, as shown in Figs. 4, 5, and 6. The bottom of the bucketzis provided with an opening, (1, (shown in dotted lines at Fig. 5,) which is partly closed by a pivoted block, 6, carrying an arm or counter-weight,f. The opening d is just of sufficient length to allow the coin a to pass through when the block e is rotated clear thereof, as hereinafter described.

To the bucket z, I pivot at 9 an arm,'h', which is normally kept in position across the opening cl by an arm, 13, having a counterweight, j, but which is moved out of this position by the weight of the coin entering the bucket z, the counter-weight then being brought immediately over the arm w, so that when the arm 10 is depressed by the grooved wheel n, rotating when the handles of the machine are operated, the arm 10 will be caused (by the coming into contact with it of the counter-weighty) to descend also and operate the index 8, so as to indicate theforce exerted.

The chute b is formed with an opening, it, in its bottom of such a size that any coin smaller than the size of the predetermined coin will pass through the said opening into the apparatus without operating the parts. When the force exerted on the handles e ceases, the counterweights y and y will raise the arms 10 and w, whereby the bucket 2 will be raised and the index .9, by the return revolution of its arbor q, carried back to zero.

Z is a finger or catch working loosely within the pivot m of the block 6, and resting upon a bar or projection, n, on the block in such a manner that when the bucket z, with a coin therein, is lowered by the handles 6 being operated, the finger or catch Z will, by coming in contact with a series of pins or catches, 0, on a curved bar, 10, fixed to the frame r of the mechanism be raised and pass by the pins 0. When, however, the bucket z is raised by the release of the handles 6, the finger or catch Z will be brought into contact with the under side of the pins 0', and being thereby pressed down will press down the bar or projection n and rotate the block 6 out of the opening d into the position shown in dotted lines in Fig. 4. The coin will then be free to pass out cular power exerted by the person using the By this means the musmachine remains indicated upon the dial t after the index 8 has returned to zero, which it does directly the handles a are released.

From the foregoing description it will be understood that the arm w can operate independently of the arm w, and therefore if the grooved wheel 1) be rotated by a person pulling the handles 0 when no coin has been inserted in the apparatus the arm 10 would be depressed without carrying with it the arm w,

and the force exerted would not therefore be indicated.

In a machine of this construction, if a perthe arm h from across the opening (1 in the bottom of the bucket z, and the counter-weight j will be thereby moved immediately over the counterweighted arm w, as shown in Fig. 4. The person then sits upon the seat at, places his feet on the foot-rests or stretchers d, and pulls the handles e toward himself in a horizontal or nearly horizontal direction. The spring j will by this means be compressed to a certain extent, according to the force or power exerted, and the hollow rod or tube 9, with the piston It, will be moved outward to a corresponding degree. This extent of movement will be communicated by the cord 'm and grooved wheel 1; to the counterweighted arms w and w, and to the index 8 and loose mark-- ing-hand s, which in this manner will indicate on the dial it the power exerted by the person using the machine, and at the same time the bucket 2 will have been lowered. From the previous descriptions it will be understood that the arm to carries the bucket z, and the deposit of the coin in this bucket causes the counter-weighty" to be raised and brought over the arm '10, and therefore when the movement of the grooved wheel 12 rotates and depresses the arm w the latter, through the agency of counter-weight j, also depresses the arm 10, and thereby operates the index 8. Upon the person releasing the handles 6 the hollow rod or tube 9 will resume its normal position, and the armsw and w, as they are raised by their counter -weights 1 and y, will respectively raise the bucket z and carry back the index 8 to zero. The bottom of the bucket, as the latter rises, will be fully opened by the finger or catch Z coming against the pins 0, as hereinbefore described, and illustrated by the dotted lines in Fig. 4:, and the coin will be discharged into the drawer r. If a smaller coin or token than that predetermined should be dropped through the slit 0, it would simply pass through the opening it in the chute b into'the drawer 1" without operating the mechanism, and the slit 0 is of such a size as will not admit of the introduction of a larger coin or token than that required.

Although I have described and illustratedmy improved machine for testing muscular power,provided with mechanism whereby the indication of the power exerted is only disclosed on the insertion in the apparatus of a coin or token, I do not in all cases desire that the indication shall be dependent on such a condition, and it will be obvious that in such cases it will be only necessary to dispense with the coin-bucket and parts for operating the same or connected therewith.

It will be obvious that, instead of using a fixed dial and a movable handle or pointer, a rotating dial can be used, which will act in a similar manner to the finger, but that the dial itself will rotate and a fixed point or opening in the machine will showv the indication, which dial may be made to return to zero when the person using the machine leaves off pulling, or may be so arranged as to return to zero by means of a knob carried to the front of the machine.

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- In a machine for testing muscular power and for indicating the same by the agency of a coin, the combination of a sliding seat, and pulling apparatus connected by intermediate devices, substantially as set forth, with a shaft, levers w w, the coin-receiving bucket on one of such levers, and its attached counter-weight j, for locking together these levers, the rack 12, serving to actuate the index hand, and means, substantially as described, for discharging the coin from its bucket.
