VFITCHIBURG, MASSACHUSETTS Foo-r: EXERcIsE R This iavennon relates t afdevice a; application to thesOl S, otthe feet for ex'ercis .ing the feet and also for restoring foetft The principal objects of the invention: re

toprovide asimplified means forsup'plying the footpad or diaphragm with air and withdrawing it therefrom; to provide a;di-

rect connection from a motor for operating" the air-supplying means; to providemea'ns in connection with a pad ,for holdingth'e sole of the foot when the pad isexh'ansted and preventingthe foot fro descending to a too low level; and to pro'videimproved means. for holding the heel support and the toe strapvvhich is adjustable and easily, moved from one position to another and which does not get out of engagement Whensoymoved.

All the mane-Sm in this case is shown lnsidefa'bo'zi or casing 10 having a detachable inclined plate or top 11 on which" is se ta sheet metalgplate 12 spacedfromthe top 11 by bars or alarm 13,

edfor the purposeof givingthe foot excr cise. When the foot is placed in position, the sole rest s on the plate 12 in the lowermost position. Thus, the operation moves the, foot 7 structure all the way from that position to a fully extended condition and back again.

This piece of felt is an important feature, as withoutitthe sole of the foot would descend too low, and it should be designed to 4 v V diaphragn'i and the sole of the foot up very closeto the plane of the metal plate 12 and not allow it e ,1 to sink down in any deeper, nomatter if on the line 61.6

suctionis applied to the bag. It is to be no tedthat there is a hole through the piece of felt 15 through which the air is admitted and discharged.

For the purpose of operating the machine. a motor is employed connected with a source of power by lines 21 and with a push button, or switch 22 in series, so that the operation of the motor can be controlled. The

motor itself is .providedwith a shaft having .a worm 23 thereon operating a worm wheel 24% reduced speed on a shaft 25; This shaft.

"through gears 26, operates a second shaft 27 at further reduced speed, and this shaft is if."

and having two perforat10ns l4 therethrough fora purpose to be ong ring 17 secured and the inflatable bellows, one on the right and Queen the left, and that they operate oppositely and inter- 'mittently, The connections fordriving them- I provided two'cranks 28 and I29,'one of them'on oneof the gears 26. 'Each of these cranks is connected bya link '30 with the lower leaf 31 of abellows 32. The upper leaf "33 is stationary and is supported from the inside of the casing by brackets537 and 38. It will be observed thatthere are two of these from the motor are extremely simple and have very few parts likely to get out of order;

The bellows itself is practically without.-

valves. There is a passage 34 through the top 11 and into the opening in the flat cushion without any, valve whatever, through j which the air enters and exhausts,

"In bothcases the latches are connected with I the plate 12 by means of longitudinal integral upwardly at an. inclination, "lo ngi tudi-. nal slots 44 provided through the plateun der these projections.

' latches havea substantially vertical part '47 at the top connectedfwithza substantially,

Iinfthis way it will be seen 'that thelower part of the I S-curveflexes the plate .51 andholds the latch in upright position wherever it may be I the 'combination of' a plate, a bellows having and a slight. resiliency ofthe heelres't allow- In. both'cases the ing the same, it is rendered loose and can be movedalong the slot.

For Qthat purpose the heel 'rest ismade in the a form of a ri gidYU-shaped structure; and the *two' sides I are secure d to a pair of latches42. The toe strap is I formed of fiexible or elastic f 'lnaterial,'- and its endsare also secured toanother pair of latches 4 2"; fIn' the case of the toejstra p these latches have two perforations I 45 witha bar betweenthem, andthestrapf" passes throughone of the perforationsto the-f other side and thenback through theotherf and is secured toitself by .aline of stitehes-46pf believe to be a vastly "more important and beneficial mechanicalaction, namely; aposi- I tive deflation'of the, arteries'and. veins.

In a machine of the character described,

a stationary leaf supportedby said 'plate behindit and a movableleaf means for operating the movable leaf, the stationary leaf having a port therethrough, a flexible diaphragm covering said port and adapted to e inflated and deflated through said port for the purpose of lifting the arch of a foot over the diaphragm, and a pad on said plate for receiving the diaphragm and preventing its being deflated so far as to bring the foot down to an abnormally low position.

2. In a device of the character described, the combination of a supporting plate or cover, ametal plate spaced abo-ve the supporting plate and having an opening therethrough over which the foot of a patient is adapted to be placed to cover the opening, a flexible diaphragm located on the supporting plate and under said opening, means for securing the edge of the diaphragm all around to the supporting plate, a felt pad under the diaphragm projecting up nearly to the level of the metal plate and a bellows under the supporting plate having a port for introducing air into the diaphragm and taking it therefrom, the port extending through the supporting plate, bellows topand pad.

'holdin g the human foot in position over said opening, a flexible diaphragm carried by the supporting plate under said opening, means for inflating and deflating the diaphragm and means for yieldingly supporting the heel rest and foot strap at both sides thereof, comprising latches, the sheet metal plate having slits provided with upwardly extending edges around which the lower end of the latches engage.

4. In a device of the character described, the combination with a supporting plate, a thin metal plate spaced therefrom. and having an opening therethrough, an inflatable diaphragm under the opening and means for inflating and deflating the diaphragm, said thin plate having opposite slits arranged longitudinally with their edges raised to inclined position, of flexible metal strips underneath the inclined edges, latches having at the bottom an S-shaped portion, the upper part of which extends inwardly over said inclined projection, the bottom part of which extends inwardly through the slit and at the extreme lower edge under said flexible strip, whereby the latches: can be moved along the slits if swung backwardly and when pulled forwardly toward said opening, will be frictionally held in position by the engagement of the bottom of the S-shaped portion with said flexible strip.

5. In a device of the character described, the combination with a metal plate having two longitudinal slits therein and a perforation between them, the outer edges of the metal between the slits being bent upwardly at an inclination to form oppositely inclined projections, a latch extending through each slit and under each projection and extending a upwardly and having two parallel slots, and a toe strap of flexible material extending through the two slots at each side and the end secured to the center part at a distance from the slots to form loops, said strap being of elastic material for the purpose described. In testimony whereof we have hereunto af fixed our signatures.
