APPARATUS FOR EXHIBIT'ING Boo'i's 0R sHoEs.

SPECIFICATION forming part of Letters Patent NO. 658,547, dated September 25, 1900. Appia-.ation filed January 20,1900. seria No. 2,094. (No man.)

lupon the sole and heel portion of a boot or shoe, and more particularly to illustrate the action oi' a ventilated boot or shoe comprising in its construction a collapsible center or intermediate sole by means of which ventilation in the interior of the boot or shoe is effeeted,snch a structure being shown in United States Patents, Reissue No. 11,694, dated September 20, 1898, and No. 616,112, dated December 20, 1898.

of the user is brought to bear as the shoe is placed upon the ground or surface Walked upon and as the sole collapses air is forced therefrom up around the foot and out of the top of the shoe, and when the foot is lifted and pressure removed from the collapsed center sole it regains its normal position and external air is drawn in through a suitable inlet. As this operation is peculiar and novel, it can only be thoroughly demonstrated by imparting to such a boot or shoe movements similar to those of the human foot in walking, the boot or shoe being cut away at appropriate parts in order that its interior and the operation of the collapsible or ventilating sole may be seen, and one form of apparatus for effecting such de ni onst ration is herein illustrated and described.

While I have herein shown one practical embodiment of my invention, however I am not restricted thereto, as I have not attempted to show or describe the various modifications or changes which might be made without departing from the spirit and. scope of my invention.

Figure 1 is a front elevation of one form of apparatus embodying vmy invention, the casing inclosing the mechanism being shown in In the use of a center sole., such as embodied in said patents the weight section, the motor being omitted, and the boot or shoe to be exhibited is shown as firmly resting upon a tread-rest. Fig. 2 is asimilar View showing 'the boot or shoe as about to begin its forward swing, the front of the casing being partly broken out. Fig. 3 is an enlarged view ofA two shoes in the positions assumed by the shoe in Figs. 1 and 2 to mor clearly illustrate the action of the apparatus. Fig. 4. is a diametral sectional view of a portion of the means for effecting the movement of the tread-rest. Fig. 5 is a section on the line :1c 00, Fig. 4, looking to the right, and showing the ring-controlling cam detached. Fig. 6 is a right-hand side elevation of the apparatus shown in Fig. 1 with the casing, tread-rest, and some of the adjacent parts in section, the parts at the right of the line 00' 00', Fig. 1, being omitted for the sake of clearness. Fig. 7 is an enlarged vertical sectional y'view of the head of the'rising and falling carrier and the connections mounted thereon for imparting a forward and back swinging movement to the boot or shoe to be exhibited; and Fig. S is an enlarged sectional detail onA the line rc2 002, Fig. 1, of a portion of the means for moving the tread-rest.

In the act of walking the foot is placed upon the supporting-surface, the body moves forward,the foot islifted, swung forward in advance of the body, and then lowered again to thesupporting-surface; but in my present invention the tread-rest, which corresponds to the ground or floor, is moved relatively to the means which support the shoe, said means, corresponding to the human body, being of course fixed in my apparatus.

I prefer to inclose the actuating mechanism herein shown, as byv a easing A, Whichis provided With a longitudinally-slotted top A' and atransverse shelf A2 in its lower portion, the latter having secured to it an upright standard B, provided at its upper end with a vertical bearingb and secured to a cross-girt A5 of the casing. A sleeve-like bearing bprojects from the front of the standard and supports ashaft (l, having fast upon it a large worm-gear C' in mesh with a worm c, Fig. 6, fast `on a shaft cx, mounted in a vlateral bearing b2 on the standard B, said shaft also having fast upon it a pulley c', Fig. 1, to receive a band or belt c2 from any suitable source of power (not shown) by which the worm and the Worm-gear C are rotated.

As it is sometimes desirable to operate the apparatus by hand, I have provided a crankshaft c3, (shown only in Fig. 1,) its end projecting through a hole CLX in thecasing to receive a crank or other suitable device to rotate it, said shaft c3 having fast thereon a gear c4in mesh with a pinion c5, normally loose on the worm-shaft. When the latter is to be rotated by hand, the pinion c5 is clamped on the shaft cX by any suitable clamping-n ut c6. The crank-shaft is shown in Fig. 1 as mounted in a bearing b3 on the standard. A rising and falling carrier (herein shown as-a tube D) is mounted to rise and fall in the bearing b, the lower end of the carrier having coupled thereto, as at D40, the open head D of a depending extension D2, the latter being shown as a flat plate slotted at cl2 to embrace the bearing b, a collar 2 on the latter serving to guide the extension, a stout spring S being attached at its upper end to the extension and fixedly secured at its lower end by a link SX to the casing A. A carrier-controlling cam DX is secured to the shaft C in front of the extension D2, the cam-hub acting as a guide in front of the latter, a roller or other stud CZX on the extension traveling on the edge of the cam and drawn toward the latter by the spring S. The shape of this cam is shown in Figs. l and 2, and in the former the carrier is in its lowest position, while in Fig. 2 it is shown fully elevated, the carrier being raised and lowered at each complete revolution of the cam. A wrist-pin 4t on the cam carries a swivel-block d', which enters and slides in a,

longitudinal slot Z3 in an arm d4, secured to a short shaft d5, mounted in a bearing 5 on the head D', a bevel-pinion d6 being secured to said shaft within the head and meshing with a similar pinion (17, fast on a shaft D5, extended up through the carrier and having a step-bearing 6 in the head. (See dotted lines, Fig. 6.) The head D and the parts mounted thereon partake of the rising and falling movement of the carrier D, the shaft D5 moving V longitudinally with the latter; but the rotation of the cam DX operates through the wristpin connection to also rock the arm d4 and shaft d5, the partial rotation of the pinion d6 in turn acting through the pinion cli to rotate the shaft 'D5 first in one and then in the other direction.

Referring now to Fig. 7, the carrier, at its upper end, has a bushing 7, which forms a bearing for the shaft D5, the latter above said bearing having fast upon it a bevel segmentgear d8, which meshes with a similar segmentgear dg, fast on the end of a shaft D9, mounted in a bearing d10 on a backet D8, secured to the carrier, the shafts D5 D9 being substantially at right angles to each other. A hood 10, carried by the bracket, protects the gears, and the shaft D9 is inclosed, as herein shown, by a tubular casing 12, and it will be manifest that rotative movement of the upright shaft D5 will be transmitted to the overhanging shaft D9, which projects over the top of the case A. The over-hanging shaft D is attached to the upper end F of a form shown as leg-shaped, its lower end F being shaped like a foot and made, preferably, of rubber to secure the requisite flexibility and to conform as much as possible to the movement of the human foot in the act of walking, the shoe or boot to be exhibited being mounted on the form, a shoe M being herein illustrated.

When the shoe descends, as shown in Fig. 1, a firm rest must be `provided for the sole and heel thereof, yetthis rest must be capable of movement with the shoe when itis swung backward, and for this purpose I have herein shown the tread-rest as a carriage H, longitudinally grooved to engage guides hX on bars HX, secured to the casing top A at the front and back of the slot 16 therein, the carriage preferably having su pporting-wheels h, which travel on a track h', carried by a transverse partition A of the casing, the carriage moving very easily in the direction of the swinging movement of the shoe. Now when the cam DX is in the position shown in Fig. 1 the spring S draws the carrierD down.

until the shoe rests upon the tread-rest H, the form F F then being in mid-position, and thereafter as the shaft C is rotated in the direction of the arrow 50 the cam will slowly elevate the carrier, while at'the same time the wrist-pin 4 and cooperating portions, hereinbefore described, will effect the rotation of the shaft D, so that the shoe will be swung back. In passing from the full-line position, Fig. 1, to dotted-line position the heel will be Iirst raised from the tread-rest, but the sole will continue in engagement therewith, and the tread-rest or carriage I'I backward swing begins the descent of the carrier will bring first the heel and then the sole of the shoe into engagement with the tread-rest, which must have been brought into the proper place.

Any suitable means may be employed to position the tread-rest, and herein I have shown one form of means for positively reciprocating said tread-rest, so that it will be moved in unison with the shoe when engaged by the tread portion of the latter and positively moved in the opposite direction When the shoe is lifted so that the tread-rest will be in position to be engaged by the shoe when it is lowered and partly moved back from the dotted-line position illustrated in Fig. 2.

Referring to Fig. 4, the worm-gear C has suitably secured to it the flange k of a ringlike box-cam K, the periphery of which has a high portion 7.a and a low portion k2, Figs. 1 and 5, substantially semicircular each, the high portion being adapted to engage alternately two like drums N, each mounted to rotate on a pin WX in a yoke NX, Fig. 8, fulcrumed at n on a lateral arm Bm of the standard B, (see Fig. 1,) the yoke having a depending leg A N', which is held in adjusted position by oppositely-acting set-screws 60 62, mounted in a bracket B6,secured to the casing. Each drum N has, as herein shown, one end of a web or flexible belt N2 passed partly around its periphery and secured thereto at the extremity in any suitable manner, the yoke being adjusted so that when the high part Zt of the cam K is opposite a drum it will frictionally engage the web thereon and rotate the drum, the right-hand drum in Fig. l being shown in, operative engagement with the cam. The web or belt N2 is shown as passed over the top of the tread-rest H,and it is secured thereto so that the aforesaid rotation of the righthand drum will move the tread-rest in the direction of movement of the shoe M. Guiderolls 07.5 are mounted at the ends of the guides hX to support the belt, the latter passing down through the slot 16 in the top plate A and through slots 18 in the shelf A5.

The timing of the cam K and the drums is such that when the shoe is in engagement with the tread-rest and moving backward the said tread-rest will be moved in unison therewith.

In order to hold the belt N2 taut vwhile unwinding from the free drum, each of the drums is provided with a spring S5, one end of which is secured to one of the arms of the yoke NX and the other end to the drum, the latter being made hollow, as shown in Fig. 8, and open at its rear side, the spring being coiled about an enlarged portion of the spindle nx. The spring is so coiled that when the drum is actuated by the pull of the belt the spring will be unwound, the tension thereof serving to keepthe belt taut,and consequently when the drum, with the unwound spring, is oppositely rotated by the cam K the spring will be wound up again.

Referring to Fig. 1, the part 702 of the cam K will leave the right-hand drum when the shoe is lifted into full-line position, Fig. 2, by the carrier, and thereafter the left-handdrum will be rotated positively to move the treadrest H to the left into position to be engaged bythe shoe on its descent, as has been described.

The brackets B6 are shown in Fig. 1 as connected by a crossed girt B9, strengthening the casing.

The spring S depresses the shoe in a yielding manner upon the tread-rest and gives when necessary as the form F' is flexed or bent by the walking movement imparted thereto.

Referring to Fig. 3, the shoe M is supposed to be resting upon a supporting-surface, and it will be noticed that the ball of the foot and the heel are the main points of support and pressure and the toe to a lesser degree, so that the collapsible sole m is most completely collapsed beneath the heel and ball of the foot, which condition pertains when the shoe is in full-line position, Fig. 1.

The shoe M in Fig. 3 shows the foot as lifted entirely from the tread support or surface, so that the collapsible sole has resumed its normal condition, as will be the case when the shoe in the apparatus herein described is in both full and dotted line positions, Fig. 2.A

Bri'ey, the collapsible sole m comprises a thin elastic web or integument m', Fig. 3, having projections m2 on its upper and lower faces of much less elasticity,the projections on one face being located opposite the spaces between the projections on the other face, as in the patents hereinbefore referred to, and operating as therein set forth, a suitable valve m8 in the heel permitting the entrance of air when the foot is lifted. A vertical guide-rib B22 is made on the standard B to be engaged by a suitable ear D22 on the rear side of the open head D (see Fig. 6) to prevent the latter from having any rotative movement during the operation of the apparatus.

In practice I prefer to interpose a spring or other yielding buffer between the end of the set-screw 60 and the depending leg N of the yoke to provide for any inequality which might exist in the faceof the cam K, and herein I have shown the inner end of each screw as provided with a buffer 77, of rubber, which bears against the leg N'.

It will be manifest that changes and modifications may be made in various particulars in respect to the apparatus herein shown and described without departing from the spirit and scope of my invention, and so far as I am aware it is broadly novel to simulate the movement of the human foot in the act of walking for the purpose of exhibiting or demonstrating the effect thereof upon a boot or shoe.
