FOOT-{VIEASURING MACHINE.

SFECIFICATION forming part of Letters Patent No. 447,098, dated February 24, 1891.

Serial No. 347,671. (No model.)

is a full and clear description,reference being had to the accompanying drawings, forming part of this speciiication, in which- Figure l represents a top plan view of the bed-plate ot a footmeasuring machine embodying my invention. Fig. 2 is a bottom plan view of the same. Fig. 3 is a longitudinal sectional View on the line c of Fig. 1. Fig. 4 is a cross-sectional view on the liney y of Fig. l. Figs. 5, 6, 7, and 8 are details to be referred to.

Uyinvention relates to certain new and useful improvements in machines for taking the measurements of the human foot; and it consists in the constructions and combinations of devices which I shall hereinafter fully describe and claim.

To enable others skilled in the art to make and use my invention, I will now proceed to describe its construction.

In the accompanying drawings, A represents a bed-plate, whose surface is slotted transversely and radially at a, ci', and h in a manner substantially similar to that shown, described, and claimed in my former patent, No. 428,875, dated May 27, 1890.

Vithin the transverse Aslots a and radial slots a and Z) are mountedv to slide blocks B, Whose sides may be 'grooved or channeled, as shown in Figs. et and 5, to receive the side walls of the slots, whereby the blocks are guided and held fromdisplacement in the slots, and said blocks have projecting from their under surfaces pointed pins c, While from the upper surfaces ot' the blocks project the lingers d, between which the foot is held when the measurements are being taken. At the under side of the bed-plate is a plate C, whose combined outer walls may approximate the shape of the humanfoot, said plaie being divided longitudinally into two parts or sections g and 7i, whose upper surfaces `at one or more points are provided with lugs Z, adapted to engage cert-ain ot the transverse slots ofthe bedplate, whereby said sections may be moved outwardly in opposite directions by a mechanism I will noW describe. These sections C/ and h are connected with rods D and D', which, after being secured to the sections, ei;- tend along the under side of the bed-plate toward the side ofthe machine and are provided ATENT OEEICE.

with set-screws c or other holding. devices. p

From this description it will be seenn that when the rods are pulled apart the sections ot' the plate C are caused to separate and move in opposite directions to expand the sections of the plate sufiiciently to enable the foot to be placed between the iingers d of the blocks.

The blocks B, which carry the pins, are arranged in pairs-that is, the blocks on one side are connected with those blocks on the opposite side directly in line with them by means of springs E, whose ends are fastened to said opposite blocks substantially in the manner shown in Fig. 2, whereby when the sections of the plate C are moved outward to expand the machine or to increase the distance between the fingers the springs are distended, and when the rods D D are released these springscontract and draw the blocks inward against the foot. At the same time when in this latter or closed position these springs enable the blocks to yield to correspond to the irregularities of the foot.'

The blocks F F at the heel and toe p0rtions of the-machine are somewhat extended below the under surface of the bed-plate, and they have holes f in them at an angle and adapted to receive continuous springs G G', one of which G is located at the toe portion and is adapted to pass through all the blocks at that point, so that said blocks are practically bound together, while the other spring G is at the heel portion and is passed through the blocks at that portion in the manner and for the purpose described for the other spring.

Aside from the blocks at the -heel and toe IOO carnose and 71 and has its outer end connected to a n ut J, fitted upon a screw-rod K, that extends longitudinally through the machine and has its ends provided with right and left threads, as in my former patents. The nut .I carries the toe-piece, and a similar nut L upon said screw at the opposite end carries the heelpieee, and the twonuts are so disposed that the continuous springs E at the heel and toe portions bear against their ends, whereby when the screw is turned the nuts are caused to move in opposite directions to carry the heel and toe pieces outward in their respect ive slots, and as the springs E bear against said nuts it is obvious that as the nuts move outward the springs are distended and bear against the walls of the openings f in the blocks at the heel and toe portions to cause the blocks with their pins and finger-pieces to move outward in their slots. XVhen the screw is turned to move the toe and heel pieces outward, as just described, the movement of the nut J is transmitted to the V-shaped plate I between the sections of the plate C, and this plate I, being wedge-shaped, it forces the sections g and 7?. apart to cause their outer walls to press the side blocks outwardly in their slots.

In order that the instep measurement may be accurately taken, I employ a spring-plate M, which lies on top of the bed-plate and has one end secured thereto at r, while the other end is unattachcd, and after being passed through a guide-plate N, secured to the bedplate near the free end of the plate M, is secured to one end of a rod or iiexible strip s, whose outer end is att-ached to a screw-rod O near the end portion of the machine.

Secured to the plate M, or simply loosely lying thereon, if preferred, are transverse straps I), suitably graduated and extending between the lingers toward opposite sides of the machine and designed to be passed over the instep and forward part of the foot to take the correct measurement thereof. Frein this description it will be seen that when the heel and toe pieces and blocks carrying the lingers and pins are adj usted against the foot, as previously described, the screw-rod O is turned, thereby drawing upon the flexible strip or rod s. This movement tends to pull the free end of the spring-plate M rearward, and as the opposite end of this plate is rigidly held the spring-plate is caused to curve upwardly at its central portion (see dotted lines in Fig. 3) to lit under the hollow of the foot. This plate M therefore operates with the straps to insure a perfectinstep measurement. y

The mechanisms described are simple in construction, notliable to be disarrangcd, and may be used in connection with the base, frame and connections shown, described, and claimed in my former patent, No. 428,875, dated May 27, 1890, and, if desired, may also be used with or without the 'diagram shown in the Patent No. 322,238, granted to me July ll-, i885.

If desired I may employ the blocks 13 (shown in Fig. (i) and which will be provided with lugs t oh their sides to permit them to be inserted through enlarged openings t in the slots and then retained in the slots. Then these blocks B are used, I may dispense with channels or grooves iir their sides, as the lugs prevent the blocks falling out of the slots.

The operation of the machine is substantially as follows: Vhen a foot is to be measured, the screw K is turned to move outward the heel and toe pieces and the blocks which are connected to them by means of the springs E, the sections g and V7i being also moved outward to press the side blocks aside. As it is desired to make the distance between the lingers greater than the width of the foot to enable the latter to be placed readily between said fingers, I then draw upon the rods D D to fully expand the machine and secure the blocks in this outward position by means of the set-screws with which the rods D D are provided. The foot being now placed in position between the lingers, the screw is turned to cause the heel and toe pieces to move inward against the ends of the foot to determine the correct length of the foot, which is made known by any well-known form of gage or scale on the bed-plate or otherwise. The set-screws e are now released to permit the springs E to draw the blocks B and sections g and h inward against the sides of the foot, after which the instep measurement is taken and the correct outline of the foot is made upon the underlying diagram or sheet by the pins c in the manner set forth in my former patcnt'before referred to.

In the detail Fig. 8 I show one of the blocks having a lever XV pivoted to its upperflange portion, said lever having a foot portion V, by which the block may be held against inward movement by the spring or otherwise, asthe foot portion V of the lever'operates as a cam against the bed-plate to prevent the block being pressed inward along its slot. This construction is desirable when it is necessary to adjust any one or more of the blocks independently of the others.
