FOOT MEASURER I Filed A ril 24, 1930 4 5; 7- 9" .1, lllll jllll'll width sizes are commonly designated by letters spaced one-twelfth of an inch apart. With these facts in mind, the following-described matters will be more readily understood.

For purposes of most complete convenience, three sets of scales are placed upon the tape itself-one upon the upper face of the tape, and two upon the outer side of the tape. Upon the upper face of the tape as it is extended from.

the or reel 1 put a scale of length sizes so.

positioned as to. read progressively upward measuring from the abutment plate 1'7, as indicated by the scale markings S, 7 and e on the extended portion oi the tape shown in Fig. 5.

Upon the outer side of the tape, so as to be visible through the window in the top oi the casing when the is partly rolled up on the drum or reel 8, is a second length-size scale, the position of which has been determined by extending the tape to a distance equal to any given length size, as measured between the abutment plate 1''! and the opposite face of the casing 1 and then so locating the scale on the outer side of the tape and visible through. the window that the numeral representing that particular length size will be oppositethe pointer 23.

Located on-the outer side oi the tape also is a second scale shown in Fig. (i on the part of the tape to the left oi the scale last described above, which second scale is graduated at intervals of one-twelfth of an inch, namely, the intervals of shoe-width size,'but marked with the numerals of length size running in inverse order. The position of this second scale on the outer side of the tape has been determined, in a manner to be hereinafter described, with reference to a scale of shoe width-sizes placed upon the top of the casing 1 below the window as shown in Fig. 5, the letters indicating width size being spaced apart one-third of an inch. To locate this second scale upon the outer side of the tape, the tape is extended till the abutment plate 17 is separated from the opposite face of the casing l by a distance equal to the width of a given width size-let us say 713 and the width size scale mark '7 on the above-described second scale on the back of the tape is placed opposite the B on the scale on the top of the casing and. used as a point of reference for locating the remainder of this second scale on the outer side of the tape.

There is also a second scale of width sizes placed on the front cover plate 2 above the curved window 24, the top edge of which is an arc of a circumference corresponding substantially with that of the surface of the drum or reel 8, and centered upon the axis of the drum. The letters on this scale on the cover plate 2 are spaced radially against leaders or graduation marks radially arranged, as shown in Figs. 1 and 9, and spaced at the curved top of the window at intervals of onetwelfth ofan inch. Through the window 24 is visible a portion of the back of the drum or reel 8 upon which has been placed a scale similarly graduated as to spacings but bearing lengthesize markings in reverse order. The scale on the back of the drum 8 bearing length-size markings spaced as aforesaid is located upon the drum by extending the tape 14 a distance equal to a certain width size, which is, of course, based upon an element of length size, andplacing that length-size figure upon the scale "in; question opposite the correspending width-size marking on the scale on the cover plate 2 above.

Although I have shown in the drawing the window 24 having its top edge coinciding subwearer stantially with the curve of the reel surface, it is to be understod that the top edgemay be placed lower, so long as its curvature is centered on the axis of the reel, in which event the spacing of the letters of the scale above the'window will be condensed, as the letters are, in any event, placed opposite leaders spaced to coincide with radial leaders or graduation marks on the back of the (humor reel, which radialleaders are spaced so as to indicate the angular displacement of thegreel occasioned; by extending the tape a distance or amount equal to a unit of shoe widthsize variation, namely, one-twelfth of an inch.

The operation of my device is as follows:

To measure length of the foot, the tape 14 is extended and the tape is applied to the sole of the foot with the longest toe in contact with the abutment plate .17 and the heel in contact with the opposite side of the casing 1, or vice versa( The steel tape 1d, owing to its curved construction, will extend outwardly in a fairly rigid condition, -thus maintaining the upright position of the abutment plate 17 in a parallel relationship with the opposite side casing and greatly facilitating the application of my device to the foot.

When the device is removed from the foot, the tension of the spring 11 tends to revolve the drum or reel 8 and wind up the tape 14 upon it. Such action is promptly checked, as the device is removed from the foot by thumb pressure upon the brake button 20, so that scale readings may be observed with the tape at rest and extended to the extent that it was extended by the foot. The length reading may then be taken at either of two places, namely, either from the scale on the upper face of the tape, where it is extended, reading the scale with reference to the adjacent edge of the side casing 1 or from the conventional lengthsize scale on the outer side of the tape which has now come into view in the window on the top of the casing l. The reading here is taken with reference to the pointer 23.

To measure the width of the foot, the tape is extended and applied to the foot across the balljoint portion thereof, with the sides of the foot embraced between the abutment plate 1'7 and the opposite side of the casing 1. The second scale on the outer side of the tape, namely, that beari'ng length-size markings but graduated at intervals of width size, now appears in the window on the top of the casing 1, and a reading is taken from the scale of width-sizes beside the window on the top of the casing 1 at the point opposite that length numeral, on the scale now appearing through this window, which has been previously 13H determined as representing the length measurement of the foot being measured.

A width reading may also be had by observing, in the window in the upper part of the cover plate 2, .(Fig. 9) the position of the previouslyit ascertained length-size number on the scale on the back of the drum as related to the lettered scale of width-size markings on the cover plate above. It will be readily understood, of course, that this last-described means for ascertaining M width size is a supplementary means added for the purpose of further convenience. It will also be readily understood that either of the lengthsize scales upon the tape may be dispensed with and use may be made of the other by taking readings at the appropriate place in the manner described.
