inventiony relates'I tok improvements in a root' measuringI device of they typev which is' used to measureV they footl in tneterrns of: shoe sizes forpr'oper ntti'ng' of shoes: VThe footrneasurifng device isv of the typ-e for accurately `deternfinin'g Ithe length size measurement both* overall from heel to toe and2 vfromI neel'` to-loall,` and the width size measurement which is automatically'adjusted tocompensate fcrvariations in length size read either overall or'fronr heel to'ball.

'I'hev present' inventiony i's an vimprovement over the foot measuringdevice disclosed in my Patent'sN'o's. 1,582,636, granted; April 27, 1'9'26, and 1,96'2;101, granted June'5, T934.A Injmy prior Patent' No; 1',582,636` thev iontmeasuring device com`` pressure against the toe oppositesidesof the ieot."

It" is an iob'iect of the' present invention topro'- vide a foo't" measuringdevi'cewhi'ch will automatically adjust itself` about the foot;` to" bear evenly with uniform-,pressurevatf allpoints ofv contact and lieeil and; onfv the with tne foot whereby the proper shoe:V 'si'zevin prises a casing having" a heel plate Whicliis engaged by the inside margin and heel `of the foot, the casing having a longitudinally' movable toe plate for' indicatingL the overall' length oft the foot,

the toe plate being' provided with' a laterally mov-vv able side yplatefor indicating the' Width ofthe foot. In this prior device the rooti's placed on the ilo'or or: other support and the device is free to adjustA itself around the foot. One' objection to this prior foot measuring device is that the side` plate, although freeto move'inwardly against the foot, cannot be pushedI outwardly by lateral pressure ofthe foot and requires amanuaf op'- eration by the' tter to' avoid incorrect indica'- Tlie device in my Patent' No. 1,962l01l has a bed' plateup'on which' the foot' must be accurately placed in orderto" obtain correct measurements; j y

' Itl iscommon practice in'k shoe' fitting todejtermine the proper shoe size by measuring onlyone foot.

The purpose of this flexible indef pendent movement of the measuring means for Veach foot will be more readily Aapparent from the subsequent descriptionof the use of the ldevice Y ias a whole.

AThe inward movement of the slide 54 with respect to the rod I0 is limited bythe stop member 18 and thev outward movement is similarly limited byjaj stopf12.v The outerarms 14 ofV the platesV 46 extend transversely and outwardly with respect to each of the measuring sticks 22 and L overlap the top .and bottom sides of the sticks y V22. vThese 'outwardly directed arms V14 provide ,means for mountingfthe outwardlymovable side plates 18, mechanism beingprovided for reading Y its associated arms 14.

It win be .understood that] the V,mechanism j through which each of theplates 16 is mounted. is thesame on each side of the double'foot measuring device. Vertical pins 18. andf are fixed to the. arms 14.r .The pin 18 forms aY pivot for the movable lever Y82 which is vconnected by a Apin 84 to' an arm 86 ywhichextends at a` rightangle Hfrom and is f xedat its outerend to the A,side plate `turned away from the inner surfaoefofthe'heel plates. The innerendsr 3 I` of the `heel plates are bent away from the-leaf springs I4 and are iiizedV I Y,to the 'diagonally disposed rods 438 which are' ati tache'dat theirrouter ends 40 to the outer ends y-ofthesticks 22: Y 'Y 16.

inner part of the casing 96 forms a toe plate |04 adapted to engage thev toe of the foot.

'The foot measuring device is'placed on theiioor or a suitable platform, restinguponthelfeet 30 and 3| and the feet V82so that itis free to readily n move about-on thesupport. The operator, while Y holdingthe. device by the handleY I2, "pulls forwardly on the handle 58 thereby causing the slide V54. to move'jforwardly and transmit movement .through the vlevers* 62 and'66 tothe toe, plate means. .The toeplateszwill therefore bemoved forwardly tothe full extent of the permitted movementand at the same timethefsideplates Q16 will move outwardlywith respectlto thefmeasuring sticks 22:" 'I'he 'device is then ready'ito receive the feet'of theperson whose'feet are to be measured.

The properlength size'may then be read" from the scales" on the strips 28. y

Accredited authorities` recommend that foot measurementsbe taken with the foott extended to its full extent whi'ch'mayoc'cur v under' conditions; ofr standing, or walking.'` Thus it is` pi'feferableV that an individual foot be measuredY with the: entire; weight of the body applied' toV that footi Tlie'recognized military authority, Colonel Munson, recommends that marching shoes be tted by taking the measurements of; a foot with theentire weight ofthe body plus a weight' equivaient to a forty-pound pack Vapplied to the foot'.

The recommended: practice,y however, is. not generally followed and shoe' fitting devices karel used with the person whose foot`v` measurements arejto be taken in a sitting position or in a. standing position with the weight evenly distributedbetween the fjeet. Although ..u recommendthat my device be used in a manner that will' eliminate so far as possible the exercise ofY judgment on the part ofthe operator so that the device may be used by untrained' operators, it will. beunderstood that my device will. give results comparable to, other devices, even'. though the. recommended practice. is notfollowed.

In using my device, the-overallior heel to toe length scale. is' first read. Thev overall length size may be suiiicient4 infittingfcertainrtypesoffshoes to the feet, but I have shown in Fig. 1 theiprovision of separatescales` for reading the heel to ball length in terms of` shoe size. It will be understood that a normal foot will measure the same shoe size whether the measurement is taken overall or from heel to ball. With my device the heel to ball length size may be read by the operator using his thumb to nd the ball joint and reading across on the heel vto ball scale, which scales are arranged inwardly of the measuring sticks with reference to the overall length scales. If the reading of the heel to ball length size indicates a larger size than the overall length size, the feet may be tted to shoes of the larger size. For example, in Fig. 1` the foot shown measures 61/ overall and 71/2 heel to ball. In such case the foot should be tted to a 7% shoe size, or at least to a 7 shoe size., This tting will leave more room between the end of the toes and the end of the shoe, but the ball length of the shoe will length; Asize [that the ptoe plate.: movedz forward; itlbeing? understoodth'atta 9:-G-ifoot, is wider than a foot in the.` standardi'systemof shoe sizes;

y The proper; sizewidthnmayfbe readilyi determined fromv the? position*l of thefindicator |1I2f om the lever 82 withfrespectto.the'fwidth. scale.-v lull.u `It should be understood thatA as 'the weight'. of/t'he bodytis: appliedto,A theefoot,` the; sides' of the foot will?. spread,`y outwardly andi', with myA device: the spreading of-,Lthez foot willY cause. the; side` plate '|-6I to move outwardly; with` respect.; to the; measuiting'stick..so.that` an. even pressure is-r, applied to. both sidesiofy thefoot. .It the foot' were. resting onia bed plate with a fixed sidebanthe foot would 'have' to. move. on` therbed' plate to accommodate thespreading of' the 1 foot', otherwise: there would' be too; greatapressure against the.y si'de bar. If`r it.Vv has been determinedfythat thef feet should befi'ttedfto.l shoes. of' a lengthl size greater than. that" indicated by the overall: length sizey scale, thetoe. plates should rst'be moved forwardly sowthati` theV selected? overall' length size-- is indicated before reading the width size scale: For example, in` Fig. 14 if itisk determinedA tof fit theV shoes to a 7% length size fromr reading the heel to ball' scale, theH toe plates/will' be moved forwardly until'll/g' is indicated onv the overall scale and"J the width measurementv willtl'ien be read; Thiswoul'dindicate a B widthand the feet wouldfbe-i'ltted to 'lll/2" Bv` shoes; whereas if the shoesY were flttedfr'om the overall length scalev withoutv readingl the heel to ball scale; the feet would be'iitted` to 6%- C shoes.

It will beunderstood that it is advantageous to use thespri'ngs; 48 and 92v forcausing the toe plate-andthe 'side plate to resilientlyfr'emain in contactl with thev foot under light Apressure but thatV the device could still be used without the springs if the operatoruses care in-pressinglthe toe-'1 platej and-*side plate intoY contact lwith the foot'.

' Fig. '7l illustrates a` measuring devioe'adapted to measureu one foot at a-y time: Thus thedevice asv shownV in Fig; 7 wouldbe used in the' position shown for measuring the left foot and then turned over to measure the right foot. The device as shown comprises Athe central measuring stick H0, the heel plate H2, the movable toe plate H4 and the movable side plate H6. The toe plate H4 is guided for movement on the rod ||8 and is normally held in retracted position by the spring |20.
