ATTORNEYS Patented Sept. 29, 1931 MAX KAPPNER, OF CINCINNATI, OHIO ARCH SUPPORT ADJUSTER Application iiiea riuy a, i929. seriai Np. 375,835.

My invention relates to improvements in devices foraltering the configuration of arch supportsand is particularly adapted for use in connection" with'V arch supports for the hilmanfootmade in accordance with Vthe teachings of'Lett'ers Patent of the United States 1,395,498 issued to me November' 1, `1921.`v

It will be understood that malformations of the foot vary so greatly that each foot fitted is apt to present an individual problem requiring some special rchange of the configuration of the metal portion of the support. The purpose of my presentV invention is to provide a device 'capable'of making all kinds of such changes and to a slight or substantial degree as the particular foot to be fitted requires. H

` Another object of my invention is to enable greater pressure to be brought upon the forward 'or rearward orv upon the -inside or outside of the support as needed, instead of Va uniform pressure Therefore, I provide fmeans 'for adjusting the position of the pressure block so asy to secure such special pressure or pressures instead of the uniform pressure.

vAnother object of my invention ist yprovide a device in which the lever in either using 30 `or n'omusing position is completelyout of `the way, where it will not interfere with those passing the benchto which the 'device is secured.V v Devices for this general' purpose 7 heretofore made have' been so generally protruding from the bench as tobe likely to injure those passing orbe itself broken 'of:l

c Another object of my' invention is `to 'pro- 7 vide an' anvil table top on the device which together 'with' thefpressiire'block provides means for making every change or alteration necessary ltobe made on an arch support. c I also'provideia specially'forined hammer for taking'vc'are of all thefvarious uses to which the` deviceiis to be put, aside from the changes made by pressure delivered through the pressure block.

-f y In the particular embodiment'of my invention selected for illustration Figure Y1 is a vertical.sectionfthrough the provided on the handle device, the device being working bench,

Fig. 4 is a plan view of porty adapted to conform t every bone in the foot, and

shown secured to a F 1g` 2 is a. top plan view ofthe device,

of the device,

,55 o the curvature of Fig. 5 isa view `of my' specially formed hammer.

Referring now to ticularly Figs. 1, 2 and 3 the drawings and pai'-,

, the device is secured to any suitable work table or bench 6 by means of screws able manner. cured between tain'the vise in open position as 7 or in any other suit- The double arm vise 8 is sethe base 9 and anvil 10 by means of thumb screws 11, member being free to reciprocate on 9. A rod 12 threaded at bothl its ends is sei cured at one end -13 to the anvil tabletop table top. 5

the vise the base a stop nut 15 out- :.70 A spring 16 surto normally mainshown in Fig. 3. An operating handle 17` is pivoted at one end 18 to the vise member this end has a cam face 1 against 'the lower portion top to close the vise.

tion of the handle so that with the. bench or table is secured.

A metal pressure block .'ioned is adapted to have lated bythumb set screws varied directions. provided 'on its top 8, and on" 9 adapted to bear of the anvil table A boss or stp '32 is 17 to limit the rotait will not contactr 80 to 'which the device 20 suitably cushits position regu- 2i, 22, 23 and 24...'.

The pressure block 20 may be made as a singlepiece :or may be split centrally or otherwise so as to have pressure exerted in more The anvil table top 10 is surface with an embossnient 'centrally depres arch sed in which the may be adjusted toV 'conform tothe particular curvatures of the cuboid and'scaph- The table top is er embossinent 26 n which the arch may bev adjusted to conform to the curvature of the metatarsal bones.

\ provided with apertures which the spur of the arch The table top is '27 and 28 upon is placed'so as not 100 to injure the spur in lowering the arch. A rounded flange 29 on the anvil table top is provided with a vertical aperture 30 through which rivets may be driven out of the arch support and the longitudinal aperture 31 is provided therethrough so that the rivets may be taken out of the flange.

In order to change the configuration and curvature of the arch 33, it is placed between the pressure block and the face 34 of the anvil table top with the metal portion of the arch in contact with the pressure block. The face 34 is formed to prevent flattening of the metatarsal portion of the arch support when pressure is applied. Any of the set screws Q1, 22, 23 and 24 are then adjusted as desired, and the operating` handle 17 is raised to whatever height is desired in order to bring pressure upon the arch 33 to increase the curvature of the arch support. vWhen the handle 17 is in its extreme upper position it becomes locked there due to the then position of the cam 19 as shown in Fig. 1.

In order to flatten or lessen the curvature of the arch 33, it is laid upon the anvil table top with the spur 36 over one of the apertures 27 or 2S and the hammer 37 is used to apply whatever force is necessary to lower the arch support. This hammer 37 has any suitable handle 38 and has a metal tube member 39 to rigidly secure the

raw hide heads

10 and 41 to the handle, the head 40 being flat and the head 41 being rounded. In order to change the curvature of the flange 12 of the arch support to conform to the particular curvature of the scaphoid bone and instep, the flange is laid upon the rounded flange 29 on the anvil table top with the metal portion up and the flat end 41 of the hammer is used to change the curvature of the flange 42. If it is desired to remove a rivet from the arch support, the rivet is laid over the aperture 30 and removed by tapping the rivet with the hammer 37 and any suitable punch. In order to change the arch support to conform to the curvature of the metatarsal, the arch support is laid over the embossment Q6 and the rounded end 41 of the hammer used to give the necessary pressure. If the arch support is to be changed to conform to the curvature of the cuboid and scaphoid bones, it is laid upon the embossment 25 and the rounded end of the hammer used to make the change. i
