An object of the present invention is the pro 511 vision of a shoe having a transverse foot lift which may be adjusted to feet of all types. Another object is the provision of an adjust able transverse foot lift ?rmly mounted in a shoe which will give the foot ?rm support in any 101 adjusted position. ‘ Another object is the provision of 'a shoe with an adjustable transverse‘ foot lift by means of which displaced bones of the feet may be grad ually returned to their normal positions without 1511 discomfort to the wearer of the shoe. A further object is the provision of an adjust able transverse foot lift so mounted in a shoe as to give the sole added strength in place of weak ening it as in most known devices. A ‘further object is the provision of a device 2 . of this character of very simple construction which may be placed in shoes without adding materially to their weight or cost. In the present day with paved side-walks and 25:‘ roads, the bones of the human foot are becoming displaced by constant walking on unyielding sur faces resulting in a good deal of discomfort and suffering. For some time past many attempts have been made to remedy this situation. Shoes 36: are being constructed with arch supports but This invention overcomes these objectionable features by providing an‘ adjustable transverse foot lift by means of which all the displaced bones of the foot, including the arch, may be h gradually worked back into place without any 5' discomfort to the wearer of the shoes in which it is mounted. 'I’his'itransverse lift includes a stiffening elementimounted in the sole of the shoe giving it added strength. The present invention consists essentially of it)? an adjustable transverse foot'lift ?rmly anchored at one‘ end in the heel of the shoe with its for ward end slidable in a plate mounted'in the sole of the shoe, means-‘operable outside the shoe for adjusting the lift by raising ‘and lowering it 15': along one side thereof and means for ?rmly holding the forward end in its adjusted position, as more fully described in the following speci?ca tion and illustrated in the accompanying‘draw ing, in which ' ' . 26'!‘ Figure 1 isf'a vertical section taken through the transverse foot'lift mounted in a shoe, Figure 2 is a plan View of the transverse lift mounted in position, with part of the upperv of the shoe broken away, 252 Figure 3 is a transverse section taken on the line 3—3' of Figure Land 2 ~ ' ‘ Figure-4 is a fragmentary section taken on the line 4-4 of Figure 2. ' ' Referring more‘ particularly to the'drawing, A 30these are unsatisfactory for the reason that no is a-shoe having'mounted therein a transverse‘ two people’s feet are alike so that a support‘ foot lift-B. The shoe A is of the usual construc which would suit one person would not suit an other. Adjustable arch supports have been pro 35v duced but these were not entirely satisfactory for several reasons. First of all they gave support to the arch only which, while it alleviated the discomfort to a certain extent, were not entirely successful because the trouble was not caused by 4 the fall of the arch alone but by the displacement of other bones of the foot as well. Secondly, in order to obtain the adjustment, they were so mounted in the shoe that after short use they became loose'and teetered from side to side re 45 sulting in further discomfort. Thirdly, they weakened the sole of the shoe lying under the support. Lastly, in certain adjustable arch supports, in order to'obtain adjustability, the forward end of 50 the support is free and is held down only by a light insole. It is quite obvious that these sup tion having an outsole I0, heel . I I, insole I2, sock lining I3 and upper I4. A metal shank I5 having strengthening ribs I6, 35*» is inserted between the sole I0 and the insole I2 either of which, if necessary, may be cut out to receive said shank. "The transverse foot lift B comprises a resilient plate I‘! shaped to ?t snug ly within the shoe over the insole. I2. The plate 40“ I‘! is provided with a raised portionVIB adapted. to lie beneath and ?t into the arch of the foot. This raised‘, portion I8 extends rearwardly be yond the arch into the heel section of the plate, as at I9. The forward end of the plate I‘! is 45: relatively wide and terminates short of the main bending point. of the sole of the shoe which ex tends substantially along the line 20. This for ward end of the plate I'Iis cut at 2| and 22 to form a tongue 23 which is' bent downwardly at 50" ports would continuously press upwardly against 24 and then horizontally at 25. This cutting of the plate forms a'pairof shoulders 26 and 21, the ball of the foot causing a certain amount of one lying on each side of the tongue. discomfort, and would eventually break through 55~the insole thus damaging the shoe. , The transverse foot, lift is-fastened in the shoe by means of screws 28 or any-other suitable fas- 55 ; 2,114,089 tening means such as rivets, nails, etc. The screws 28 are situated beyond the edge of the shank l5 so that they may pass through the soles of the shoe into the heel in order to fasten the lift ?rmly in place. These screws are placed adjacent to the outer edge of the plate I‘! thus leaving its inner edge free. The tongue 23 is adapted to pass through a slot 29 in the insole l2 andya slot 30 in the shank l5 adjacent its through the slots in the insole and the shank. The shoulders 26 and 21 by bearing on the insole, stabilize the transverse lift and prevent it from teetering which would in time, prove injurious to the foot. When the plate is lowered its resil iency moves the tongue forward in the grooves, the shoulders also being free to move forward. A? feature of this invention is the fact that the transverse lift may be adjusted in such an easy manner, it only being necessary to- place 10 the shoe on the foot and turn the adjusting screw An internally and externally threaded sleeve ' until the foot feels comfortable.
