Extending vertically through 50 Another object is to provide a method and these openings 1 and 8 is a series of vertically apparatus whereby a foot suffering from pronamovable riser bars or gauging elements 9. These vtion may be elevated and restored to its proper bars in the embodiment illustrated are rectancondition and a measurement of thev normal gular in cross section and are arranged in 1onshape of the arches in that condition may be gitudinal and transverse rows as may be seen 55 from Figure 4. The bars are in mutual contact with each other but are slidable vertically with relation to each other and with relation to the plates 3 and 4. Each bar 9 is provided with a slot I 0 penetrating the same in a lateral direction and extending lengthwise for a considerable portion of the length of the bar. Traversing the slots I0 of each transverse row of bars is Ia cross supporting plate I I. The ends of the bars I I rest in the channels 6 of the bars 5 and are movable in said channels lengthwise of said bars. The plates II maintain the riser bars of a single transverse row in alignment with each other and restrain the movement of said bars longitudinally of the device so as to cause each row to move as a unit. Each plate II is additionally supported by a pair of hangers I2, one of which is illustrated in detail in Figure 7. This hanger has a vertically extending shank and is bent over at itsl upper end to forma hook I3. A slot I4 is formed to extend vertically of the hanger through the horizontal portion of the hook I3 and downwardly along the shank of the hanger a sufficient distance to accommodate the height of the plate I I. As will be seen from Figure 6, the ends of each plate II rest in the slots I4 of a pair of hangers and the hooked ends I3 are passed over the upper edges of the bars 5. These hangers are thus restrained to slide lengthwise along the bars 5 with the plate I I and the row of riser bars 9.
Extending transversely of the device between the bars 5 is a pressure plate I5 against which the last row of bars 9 engages. This plate is supported against rearward movement by one or more springs I6 carried by a transverse yoke Il supported by one or more adjusting screws I8, The springs I6 may extend forwardly through perforations in a backing plate I9 which in turn is supported by transverse bars or pins 20 fixed in the side walls 2. The plate I5 has its forward movement limited by adjustable stop screws 2I. At the front end of the device the bars 9 are engaged by another transverse pressure plate 22. Clamping screw 23 having a manipulating head 24 is threaded into a stop plate 25 secured against forward movement by stop pins 26. The screw 23 may be adjusted to force the plate 22 rearwardly against the bars 9 so as to clamp the entire assembly of bars and lock them in adjusted position. If desired a resilient plate 21 of rubber or the like may be interposed between the pressure plate 22 and the bars 9 so as to insure a uniform pressurel on all the bars.
When the bars 9 are loose or unclamped they may be moved downwardly to their lowermost position as limited by engagement of the upper part of the slot I0 against the upper edge of the plate I I. When in this position the upper ends of said bars come flush with the upper surface of the top plate 4. By placing the bars under slight pressure by adjustment of the screw 23 any one or more bars may be moved upwardly so that its upper end projects above the plate 4 and it will be frictionally retained in such position. Accordingly, if a foot is placed upon the top plate 4 with its arch portion over the bars 9, the latter may be pushed up from below until their upper ends engage with the arch of the foot and they will be frictionally held in such position. By pressing upwardly on all the bars each one will be raised to a position corresponding to the height of the arch just above it, and when all have been thus manipulated the upper ends of the bars will define a three dimensional surface corresponding exactly with that of the plantar surface measuredf The bars may now be clamped in this position by operation of the screw 23 s'o as to preserve this adjustment.
In order to assist in correcting pronation, a longitudinal bar 28 is removably mounted in slots 29 and 30 in the front and rear plates I.
These slots are so positioned as to hold the bar 28 inl longitudinal alignment with .a row of the bars 9. 'Ihis lbar 28 provides a gauge against which the inner face of the foot may be positioned to take a measurement. As pronation is the result of a laterally inwardroll or fall of the foot as a whole, by placing the inner face of the foot against the bar 28 the foot may be erected 'so as to eliminate such fall or pronation and restore the foot to its normal position. A recess 3| may be provided in the bar 28 in order to clear a prominent joint or bunion in case such would otherwise interfere with properly aligning the foot against the bar 28. Two sets of slots 29 and 3l)l are provided for the accommodation of right and left feet.
In restoring a faulty foot to normal position three parts of the arch are of special importance, and a foot specialist will usually see that these three parts are in proper adjustment, which would usually insure that the rest of the foot take its normal position These parts are the transverse arches at ythe so-called metatarsal and cuboid regions, and the longitudinal arch or scaphoid stream. suring proper adjustment of the arches at these points. A pair of clamping screws 32 is provided opposite each transverse row of the bars 9. These screws pass loosely through clearance holes in the plates 2 and are provided with nuts 33 on the inside of said plates. 'I'he screws also pass through clearancey holes in the bars 5 and the ends abut against the lower portions of the Shanks of the hangers I2 which thus serve as binding plates and to cover the slots I 0. By adjusting the screws 32 lateral pressure may be applied to one row of bars 9 so that said row may be clamped in adjusted position and independently of the other bars. The loose mounting of the screws 32 permits suiicient forward and rearward movement of the bars 9 to permit clamping the same by means of the screw 23. The hangers I2, therefore, provide clamping plates for clamping a row of bars 9 and at the same time the hanger supports I2, by means of which a clamped row is movably suspended upon the bars 5. This arrangement permits careful attention to the adjustment of that row of bars 9 which engages the metatarsal portion of the arch so that accurate -adjustment of that row of bars may be had and the bars `then clamped `to preserve the adjustment. The attention may then be turned to the cuboid region and the transverse row of bars at that point adjusted and clamped in a similar manner. 'I'his not only measures the arch at these important points, but, when these rows are clamped, the foot will be sustained in its adjusted position until all theother bars may be moved to their This device provides for inor opening 35 adapted to receive the device of Figure 4, which may be mounted therein in any suitable manner so as to be in proper registry with the mechanism thereof.
The frame 34 is provided at its ends with rearwardly extending racks 36 upon which a pair of pinions 3l may roll. The pinions are mounted on a common shaft 38 to which each of the pinions is fixed sc that the engagement of said pinions with the racks 36 insures the travel of the shaft 33 at all times parallel to a single direction. Mounted to rock on the shaft 38 is a frame 39 to which are rigidly fixed forwardly extending arms 4i! and 4I. The arm 40 carries at its forward end a wheel or roller 42 positioned to engage the surface formed by the upper ends of the bars 9 of the measuring device. This roller may move forwardly and rearwardly across the tops of these bars and may be shifted laterally along the shaft 38 so that the entire surface dened by those bars may be followed out. The arm 4l carries a forming tool, in the embodiment illustrated in the form of a grinding or cutting wheel 43. rI'his wheel is mounted on a shaft 44 journaied in suitable bearings in the frame 3S and connected by a flexible shaft 45 to a suitable driving motor 46 which, in the embodiment illustrated, is mounted Within the frame 34 below the top 48 thereof. Means are provided for mounting a lift blank 41 on the top 48 in a position for proper engagement by the tool 43. This may be done by any suitable mounting upon the tcp such as pins 'l5 or other fasteners to which the lift blank 4l, which may be of cork or other suitable material, may be securelyattached.
In the embodiment illustrated the arm 4l is hollow, providing therein a passage 49 as shown in Figure 3, which is connected by a tube 5B with a suction fan 56 driven by the motor 46, said fan having an exhaust outlet connection 52. A hood 53 may be provided at the end of the arm 4l to fit over the tool 43 so as to collect the cuttings formed thereby and carry them off by the draft of air produced by the suction of the fan 56. l
In the operation of this device the measuring or gauging device of Figure 4, being portable, may be carried to the patient or person whose feet are to be treated and the plantar arches of one foot accurately measured by setting up the gauging elements 9 to conform to the shape of the arches and clamping said elements in adjusted position as described. The device may then be assembled as illustrated in Figure 1 and a lift blank secured in position at 4l. With the tool 43 in operation the roller 42is passed successively over each longitudinal row of elements 9. As the roller passes over said elements its elevation will be varied in accordance with the adjustment of said elements. This variation in elevation will be transferred to the tool 43 by rocking of the frame 39 so that said tool will operate at a corresponding elevation with respect to the blank 4l. The roller 42 may then be shifted laterally to another row of gauging elements. Such'shifting will cause a corresponding shift of the tool 43 with reference to the blank 47 and again as the roller 42 moves over the ends of the second row of gauging elements the tool 43 executes a similar movement. When the entire surface defined by upper ends of the bars 3 has been traversed by the roller 42 the blank 47 will have been formed by the tool 43 to a surface of like shape. By this operation the tool 42 functions as a take-off element to take off the shape of the surface defined by the gauging ele-ments and the shape so taken off is transferred through the agency of the frame 39 to the forming tool 43 which latter operates to form the blank to a like shape. It Will thus be seen that the shape of the surface taken from the foot is mechanically transferred to the blank to form a lift which will fit exactly the form of the particular arch measured.
In order to form a relatively smooth surface the upper ends of the gauging elements 9 may be rounded slightly. This purpose may also be accomplished by forming over or against the tops ofthe gauging elements a flexible sheet such as a sheet of rubber or other flexible material. In Figure 1 such a sheet is indicated at 54 which may be secured to the top plate 4 by suitable fas teners 55 such as snap fasteners or in any other suitable manner. When the device is not in use a ring 56 may be engaged on a hook 51 on a rear frame 58 so as to suspend the forming tool out of Contact with the blank when not in use.
It will be seen, therefore, that this invention provides a method whereby a surface may be shaped by adjustment of the gauging elements to the shape of a foot arch and then mechanically transferred to a lift blank so as to form the latter to a like shape. By providing a group of gauging elements such as the bars 9 in laterally and longitudinally adjacent relation as shown in Figure 4, these elements may be adjusted to shape the surface dened by their upper ends to correspond with any foot surface, normal or abnormal. By the use of a sheet such as 54, which is formed to the tops of the gauging elements, a relatively smooth surface may be defined so that the action of the take-off element 42 will be smooth. The grouping of the gauging elements is such that any three dimensional surface within their range of adjustment may be formed or copied.
In adjusting the gauging elements to the foot the provision of the clamping device 32 enables the important parts of the plantar arch, such as the metatarsal and cuboid regions, to be set up with particular care and those elements clamped in adjustment.
While in the apparatus illustrated the lift is form-ed to the exact shape and dimensions of the surface set up b-y the gauging elements, it is practical by this method to form lifts of different sizes but with the same general shape. This may be done, for instance, by varying the relative lengths of the arms 4i) and 4l and pivoting the shaft 38 at one or the other end thereof. By properly adjusting the relative lengths of the arms and the location at the pivots an increase or reduction in scale may be made during the transfer of the shape from the surface set up to the blank. This may be useful Where it is desired to provide a series of lifts for different sizes of shoes all conforming to a standard shape of arch.
As it may sometimes be convenient to use the master pattern shown in Figure 4 for the purpose of measuring the plantar surface of a foot and recording the measurements rather than immediately cutting a lift by means of the cutting device, means for recording such measurements may be provided as illustrated in Figures 8, 9 and 10. An arrangement for making a similar record with a machine having only one row of riser bars is disclosed in the above-mentioned application Serial No. 43,817. Figures 8, 9 and 10 illustrate a way in which this method of recording may be applied to a machine having a gang of riser bars covering both length and width v first longitudinal row of risers.
bars 9 the slot 66 terminates in an angular cam surface 6l adapted to engage a similar cam edge 62 on a horizontally slidable indicator bar 63. In the embodiment illustrated each :slot 60 is wide enough to accommodate three indicator bars 63 which traverse the slots 6D of an entire transverse row of riser bars. These indicators may be supported upon any suitable supports 64I In the embodiment illustrated cam surfaces 6| are formed upon three riser bars in the transverse row and the indicator bars 63 have their cams 62 positioned thereon so that each cam is adapted to operate or be limited in its movement by one o-f the riser bars in that row. In Figure 8 the cams 61 are shown upon the rst, fourth and seventh bars in the row. 'I'hus each transverse row has three riser bars arranged for cooperation with three indicator bars, all slidable within the slots 66 of that row of risers.
The three indicator bars 63 cooperating with the same row of risers, extend different distances to the left, Figure 8, and each is provided at its end with a finger lug, 65 for the first bar, 66 for the second and 61 for the third. These lugs are provided so that the indicator bars may be manipulated by sliding them to the right, Figure 8, as indicated in dotted lines for the first bar in that gure.
'I'he cams 6I and 62 are preferably positioned at 45 so that the horizontalmovement of the indicator bar will correspond exactly in extent with the vertical movement of the riser bar. This relation may, however be varied as desired. The right hand end of each bar 63 has an indicating extension 68 projecting from the bank of riser bars and extending over a table 69 supported in any suitable manner on the frame of the device. Below the extensions 68 there may be fixed upon table 69 a stop rail 10 providing an abutment for the edge of a chart or record sheet 'H upon which the record may be made. When the measurement of the plantar arches has been taken by elevating the proper riser bars, the record of this measurement may be taken as follows. With the riser bars all Dositioned and clamped the first indicator bar in each row may be pushed to the right, Figure 8, by manipulating the nger lugs 65. This brings each cam 62 of the corresponding indicator bar up against the cam 6i of its riser bar and accordingly the horizontal movement to the iight of the indicator bar will correspond exactly to the Vertical movement of the corresponding riser. 'Ihe first indicator bars of each group will then extend to the right various distances as shown in Figure 9 and a curve 12 may be drawn across the ends of the extensions 68. This curve will represent the form of the arch taken along the When this curve has been drawn the bars may be returned to their initial position and then the lugs 66 operated to move in a similar manner the second bar in each group, and from the extensions thus projected a second curve 13 may be drawn upon vthe chart 1|.` The-se barsmay then be returned and the third group extended by manipulating the lugs 61, whereupona third curve 14 may be drawn upon the chart. In this manner a curve may be placed upon the chart for any longitudinal row of risers and this curve will represent the shape of the plantar arch alongthat line.
i For the sake of simplicity in the drawings the arrangement has been shown such as to record only therst, fourth and seventh longitudinal rows of risers. It is obvious, of course, that additional rows of risers may be similarly recorded simply by multiplying the number of indicator bars which traverse a single transverse row of risers. In other words, instead of three bars in each slot 60 there may be ve, seven or such other number as may be found suitable for the purpose, the cams 62 being positioned on the respective bars so as to cooperate with the proper row of risers.
With the recording means just described it will be possible to place in the hands of the shoe dealer or other person whose function it is to measure feet simply one of the measuring devices of Figure 8. He need not be equipped with a cutting device such as shown in Figures 1 and 2, but he may make a chart record of his measurements and send this record to a central cutting station where a measuring device may be reset according to the curves 12, 13, 14 of the chart and then assembled with the cutting device and a lift of proper shape cut therefrom. In this manner the equipment required` of the shoe dealer is reduced in expense since he has to provide only the measuring device and a central service may be established for cutting lifts from the charts sent in by various shoe dealers.
