Abstract
ABSTRACT OF THE DISCLOSURE
The form fitting of shoes and boots of the instant invention includes the heating of the area of the foot gear which needs to be enlarged to accommodate the foot and simultan-eously applying pressure from the inside of the foot gear to cause the heated portion of the foot gear to expand the desired amount. Pneumatically or hydraulically actuated cylinders are used within the foot gear to provide the required pressure and a number of different shoe contacting members are interchange-able to assist in shaping the expanded portion of the foot gear.

DESCRIPTI(:)N OF THE Pl:~l?ER~:D EMBC~DIMENTS
Referring now to the drawings in detail, the reference numeral 30 indicates generally the pressure applying apparatus ;;
of the instant invention. The pressure applying apparatus 30 in-cluded a compressed air bottle 31 or if desired a source of hy-draulic fluid under pressure which is controlled by a valve 32 having a hand knob 33 associated therewith. A fitting 34 extends upwardly from the valve 32 and has a pressure gauge 35 mounted thereon. An elongate handle tube 36 is connected to the fitting 34 and extends to a fitting 37 forming part o a base member 38, - ;
The base member 38 is generally cylindrical in cross section and is internally threaded at 39 for reasons to be assigned, A hollow cylinder 40 has an externally threaded re-duced diameter portion 41 at one end thereo which is threaded -into the threads 39 of the base~member 38 on each side thereof. -~
The hollow cylinder 40 has an internal flange 42 formed at the end thereof opposite the externally threaded reduced diameter portion 41 or reasons to ~e assigned.
A piston 43 i9 mounted for reciprocation in the cylin-der 40 and has a shouldered portion 44 which engages the flange 42 to prevent the piston 43 from moving completely out of the cylinder 40, The shouldered portion 44 has an annular groove ,' "~
, ~o~o~s~
45 formed therein to receive an O-ring seal 46 as can be clearly seen in Figures 2 and 18. A washer 47 having an axial bore 48 formed therein is positioned between the cylinders 40 centrally of the body 38. The opposite faces of the washer 47 are provided with radial grooves 49 to permit the flow oE fluid from fitting 37 inwardly to the central bore 48. The inner ends of the pistons 43 have a recess 50 formed therein to permit the free flow of `fluid from the bore 48.
The outer ends of the pistons 43 are provided with bores 51 to receive cylindrical bodies 52 for reasons to be assigned. Each of the bodies 52 are provided with O-rings R
to assist in holding the bodies 52 in the bores.
A yenerally circular knurled contact member 53 has a cylindrical body member 52 integrally formed thereon as can be seen in Figures 4 and 5. An elongate domed member 54 also knurled on its outer surface is similarly ~rovided with a cylin~
drical body 52. The members 53, 54 are used interchangeably in accordance with the shape to be given to the foot gear as it ... .
is expanded.
In some instances the effective length between the cylinders 40 must be increased and this is done with an adaptor 55 having a body 52 formed on one end thereof and a bore 56 formed in the opposite end thereof. A washer 57 having a bore 58 therein permits relatively short additions to be made to the ;
length of the apparatus. An immediate adaptor 59 is identical to the adaptor 55 with the exception that it is shorter in over- -all length. ~s can be seen in Figures 8 through 17 the effect-ive length between cylinders 40 can be varied to any degree , ~ 30 _ 7 _ .

, 6~)15153 ~:
necessary in order to adapt the apparatus to the foot gear needing shaping.
In some instances when found desirable to have expan~
sion from only one side of the body 38 one of the cylinders 40 can be replaced with a dummy cylinder 4 n solid at its inner end instead of having the piston 43 mounted therein.
In Figures 16A and 16B a truncated semi-spherical member M is used and has a bore S1 to receive the member 53 on ;
its upper surface. This arrangement is used for expanding the complete toe area.
Referring now to Figure 19, a hand operated hydraulic pump is illustrated generally at P. The pump P includes a manifold M, with a pressure gauge G connected thereto. Three output91ines #1, ~t~ and ~3 extend Erom the manifold M to the units to be actuated.
In Figures 20 through 22 a generally U-shaped unit 60 includes a tube 61 having a fitting 62 connected centrally i^~
thereto. One end of the unit 60 is provided with an open solid -ring 64 which is adapted to engage the outer face 65 of foot gear 66 to be shaped. A cylinder 67 is integrally mounted on 3 the opposite end of the unit 60 and contains a piston 68, connecting rod 69 and a dome member 70 as can be best seen in Figure ~2. A retainer ring 71 secures the piston 68 within the ;
` cylinder 67. In the form of the invention illustrated in Figures ,~
20 through 22 the foot gear is heated in the area to be expanded and the dome shaped member 70 is pressed toward the ring 63 centrally thereof so as to reshape the foot gear 66 as needed.

A modified form of the lnvention is illustrated in ;~ ;
Figures 23 through 25 and includes a cylinder 72 open at each end and having an internal reduced diameter stop 73 intermediate `~
the opposite ends thereof. A piston 74 is mounted in each end ~ -of the cylinder 72 and has a reduced diameter barrel 75 which :
engages a retainer washer 76 in the cylinder 72 secured in ~`
place by a lock ring 77.
,~
An O-ring seal 78 is mounted in the head of each piston 74 and engages the inner wall of the cylinder 72 to seal the piston for sliding movement therein. A socket 79 ~:
is formed in each of the pistons 74 to receive a post 80 of a dome member 81. .
A fitting 82 is integrall~ formed on the cylinder 72 and has a passage 83 extending therethrough and communicating with the space between the pistons 74. A hand controlled valve 84 is serured to the fitting 82 and to a hose 85 extending from the #2 outlet of the pump P.
