Abstract: 360,914. Boots &c. ROBERTS, F. W., Northcroft, Blaby, Leicestershire. Aug. 7, 1930, No. 23654. [Class 17 (iii).] Measuring.-The invention relates to apparatus for measuring the human foot, lasts, and other bodies and for reproducing contours and measuring sectional areas of the same, and consists in the provision of laterally-adjustable longitudinal scales for taking lengthwise measurements of the body. the scales contacting with the body and being simultaneously movable so that the body is positioned on the median line of the apparatus. In the form shown in Fig. 2, the apparatus is adapted for measuring only, whilst that shown in Figs. 6, 7, 17, and 18 is used for both measurement and reproduction. Referring to Fig. 2, blocks 7, 7a are slidable along the members 2 of a rectangular frame and have connected to them graduated bars 5. The bars are maintained symmetrically with respect to the centre-line of the frame by centrally-pivoted levers 9, 9a, and links 8, Sa, and carry riders 16 having pads 17 which are adjusted to bear against prominent parts of the foot or last being measured, the heel of which is at the same time in contact with a plate 19. A transverse member 14 is slidable along the side members 1 and supports a plate 15, which can be brought into contact with the toe and which has scales to indicate the " rise and amount of " off-set " of the same. The frame is supported by runners 3 so that, during the adjustment of the bars 5, the frame moves to bring its centre-line in coincidence with that of the foot. In the form shown in Figs. 6, 7, 17, and 18, the foot or last is supported, toe uppermost, in a vertical plane, the heel resting against a member 25 and the toe against a similar member 27. The members 25, 27 are supported by cross slides 28, 28a, 32, 32a, adjustable in two directions at right-angles by screws, racks, and pinions, and graduated to indicate settings in both those directions. The upper cross slides 28, 28a are attached to a plunger 36 vertically adjustable in a fixed part 23, the setting of the plunger being indicated by a scale 44. The lower cross slides are also secured to a vertically-adjustable post 45. Longitudinal scales 5a are connected to pins 20 secured to plates 21 slidable along fixed graduated bars 22 by levers 9b and links 8b, 8c, which ensure their symmetrical position with respect to a centre-line. A removable plate supports the foot while it is being adjusted into position. A rectangular frame 52 is rotatably mounted at 53 on an arm 51 secured to the framework of the apparatus, and within the rectangular frame is mounted a table 54, an extension of the table forming the part 23. A member 59 is fixed to the framework and surrounds the rectangular frame 52. The table 54 carries three slidable bolts 57 which can engage with the member 59 and so hold the table 54 and part 23 stationary, but which are retracted to allow the frame 52 to rotate by a cam track 61 fixed to the frame 52 and acting on rollers 62 secured to the bolts 57. Rotatably mounted in the frame 52 is a shaft 65 which has at its upper end an arm 68 carrying a recording pen 70 and a planimeter 71. Adjustably fixed to the lower end of the shaft 65 is an arm 67 carrying a curved member 73 along which an arm 76 can be fixed in any position. The arm 67 has pivoted to it at its outer end a curved piece 69 which contacts with the foot or other body being drawn. A wheel 77 to measure the perimeter of the body may be pivoted to the arm 76 at 77a. Specification 342,745 is referred to.
