Application filed @ctober 6, 1919.` Serial No. 328,552.

T0 all whom t may concern.'

Be it known that l, CesrAoNoLA OLIVER, of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful improvements in Pedimeters, of which the following s a full and clear description.

My invention relates to the art of providing proper shoes for deformed feet.

As is well known, a deformed human foot is not only very irregular in shape, but its position with respect to the ground when walking is commonly such that the stresses are not distributed so as to be within the comfortable limits. Moreover, the abnormal position of the foot often throws undue stresses on portions of the shoe when the person is walking, thus distorting the shoe .and causingdiscomfort as well as causing undue wear of the shoe.

llt is the principal object of my invention to provide means whereby measurements of deformed feet may be made in walking position which will enable a skilful Shoemaker to construct a proper shoe for the persons from whose feet the measurements were made.

rlFhe novel features of my invention are pointed out with particularity in the appended claims. The invention itself, however, together with further objects and advantages, will best be understood from the following` description taken in connection with the accompanying drawing in which- Figure 1 is a perspective view of a device according to' my invention. r Fig. 2 is a section taken on the line 2-2 of Fig. 1.

llfig. 3 is a plan view of a part of the apparatus shown in Figs. 1 and 2 illustrating a drawing of a deformed foot such as would be made from data obtained by operating my apparatus for the use of the last-maker.

Referring to the drawing more in detail, 1 is a framework in which a mirror 2 is supported by a suitable plate 3, the framework being preferably horizontal and therefleeting surface of the mirror being exposed from above when the apparatus is in use. Mounted on the frame above mirror 2 and spaced therefrom is a bar such as 4 which extends parallel to the surface of the mirror. Bar 4 has graduated scale members 5 and 6 fixed to its top and bottom surfaces, although the top and bottom surfaces of the bar may have the graduations placed.- direxploring lever 19.

,which is designed to eXtend 'toward the foot, yis formed with an upturned tip rectly thereon if desired. The bar 4 has a number of appliances associated therewith whereby the desired measurements may be obtained. rlhese appliances comprise a vertical standard such as 7 which is slotted as at 8 to permit the ready adjustment of the heel rest 9 in a vertical direction. A carrier 10 for the tape 1()LL is also adjustably mounted in the slot 8. Standard 7 is graduated at the side of slot 8 as shown at 8a, so that the height of the rest 9 on the standard 7 above bar 4 can be easily noted. Slidably mounted on bar 4 are plates such as 11 to which/are fastened a horizontal cross-bar 12 and a block 13. At the ends of bar 12 are upright standards such as 14 on which are vertically adjustable blocks such as 15 in which are mounted horizontally adjustable graduated scale or caliper members, such as 16, at the ends of-which are fastened tapes such as 16a. Near the ends of members 16 are mounted vertica ly adiustable graduated.

caliper members such as 16". ln blockl is a horizontally adjustable bar 17 at one end of which is a post 18 mounted to turn on its central vertical axis and at the upper end of post 18 is a horizontal shaft on which is pivoted a caliper member in the form of an rllhe end of lever 19,

20 for use in determining the position and form of protuberances on the bottom of the foot. The other end of lever 19 is shaped as a pointer and cooperates with a vertical scale on a plate 217 indicatingthe height of tip 20, the `plate 21 being fixed to post 18. The bar 4 also carries a horizontally adiustable block 22 on which is a vertical standard 23 having1 a vertical slot 24 therein, the standard 23 being graduated along the edge of slot 24 ,as shown at 25 (Fig. 2). Adjustably mounted in the slot 24 is a toe rest 26 and Valso a graduated caliper member 27. Y

`Parallel to the bar 4 on the framework is a bar 4. At the end of bar 4 is a standard 7 carrying a heel rest 9. lt will be understood that the bar 4 and standard 7 are providedk with the tape holder. side caliper members, toe rest. and end caliper member,

all as described in connection with bar 4, J,but that these parts are omitted from the drawing for convenience of illustration.

In the operation of my device, bar 4 and its adjuncts are used: for obtaining measurements of the left foot; and bar e and its adjuncts, those of the right toot. The center line oit' the toot is placed on the center line ol' the bar, such as l, and the heel rest, such as 9, or toe rest, such as 26, adjusted so the foot is in the position taken when the person is standing with weight on the foot in question. The outline oi the foot around its maximum perimeter is then obtained by the caliper members such as 16", readings of the horizontal and vertical positions of members 16b being taken for various positions of the block 13 on the bar 1. rl`he vertical and horizontal position of points on the center line of the toot on its front surface are taken by caliper member 27. The points above the heel of the foot on the center line tliereotl are not so important as those on the front face, and the position of such points can be obtained by one of the members 16 by moving block 13 to its extreme position on bar e. The positions of blocks 13 and 22, and consequently the position of the vertical parts carried thereby, are easily read even when the footis on the bar a, owing to the reflection of parts 13, 22, and the scale on the under side of bar 4t in mirror 2. The mirror also assists materially in discovering protuberances. These, when discovered, are explored and plotted in an obvious manner by aid of member 19, the end 2O of which can be brought against the protuberance and its outline determined by rectilinear movements of parts 13 and 17, and swinging movements of part 19 on the vertical axis ot post 13, the angular position of part 19 on its horizontal axis being noted on the scale oirplate 21 and changed as found necessary in conjunction with the changes in position of the bloclr 13 and bar 17. Cin cumerential measurements are obtained by tapes, such as 10a and 16a, tape 10aL being' particularly convenient for obtaining the circumferential measurements above the heel.

For convenience in platting the data obtained by the use of the apparatus above described, l prefer to combine therewith a square board 28 having two parallel pins, such as 29, lined thereto, and projecting therefrom near adjacent corners and ar ranged so that they may be inserted into clips such as 30 on the framework 1. The edges oi" board 23 parallel to pins 29 carry clamping' bars such as 31 which are attached to board 28 by spring members such as 32, so that bars 31 may be readily lifted enough to insert a sheet 33 to be drawn upon under the bars 31, such sheet will then be held firmly in place after it has been inserted thereunder. Any convenient form of drawing instrument, such as the square 34, may be used in transferring the data obtained by use .of the pedimeter to the drawing sheet. One edge of board 28 and the clamping members 31 are preferably graduated to facilitate the drafting operations.
