JAMES W. ARROWSMITH, OF'MOBJRISTO-RTN; NEW JERSEY.

ARCH-SUPPORT ADJUSTER.

To all whom it may concern:

Be it known that 1, JAMES W. ARROW- snrrn, a citizen of the United States, residing at Morristown, in the county of Morris and State of New Jersey, have invented a new and useful Improvement in Arch- Support Adjusters, of which the following is a specification.

The improvement relates to devices designed for the special purpose of bending and adjusting metallic plates for supporting the instep arch of the human foot and the objects of the improvement, among others, are to provide means whereby the adjustment of such plates to the contour of the foot arch may be quickly and accurately made without injuring the metal or the covering of non-metallic material usually applied to the plate; to provide a simple, compact and durable adjusting device so constructed and arranged that the arch support may be placed therein'and operated upon in various ways; and to thus dispense to a great extent with the use of pliers or the like in accomplishing the adjustment.

The improvements consist in the combination, construction and arrangement of parts hereinafter described and claimed and illustrated in the accompanying drawings.

In the said drawings, Figure l is a plan of an arch support adjusting device embodying the improvements; Fig. 2 is a side elevation of the same; Fig. 3 is an end view; Fig. 4 is a partial vertical longitudinal section.

It should be understood that arch supports of the kind designed to be operated upon by the device which is the subject of this application are designed for the relief and cure of the disease of the bones of the human foot commonly known as flatfoot, which disease manifests itself in a falling or flattening of the bony arch of the foot, comprising the calcaneum or oscalcis, the astragalus, the cuneiform bones and the metatarsal phalanges, and that the treatment of all cases which have advanced beyond the incipient stages involves the adjustment of the arch support to the depressed contour of the foot arch and then the gradual raising of the arch of the plate, and consequent raising of the foot arch, longitudinally and transversely, when required, by adjustment of the plate from time to time as tolerance is established. It will therefore be apparent that great accuracy and precision are often Specification of Letters Patent.

required in the adjustment of the plate, and that this adjustment must be made at different parts from time to time, depending upon the position of the bones comprising the arch of the foot which is being treated.

The base plate S is of wood or other suitable material and of greater length than breadth, and on either side of it near the middle thereof are mounted standards A of substantially U form inverted. Between the apices of these standards the cam lever B is mounted by means of the bosses G which have bearing recesses to receive the pintles D of the hub F. The bosses G have screw bolts I extending through them near the standards A and passing down and entering the base S, and between these bolts a block J is mounted by having the said bolts passed loosely through vertical bores near its ends, so that it may move up and down in a vertical plane thereon. Helical springs H are strung on the bolts I between the block J and the base and serve to raise the said block to its uppermost position after it has been depressed, and to hold it in such position normally. M extending downward from its lower side, and this boss is provided with a cover or cushion K of leather or other suitable nonmetallic material.

The base S is provided with a longitudinal groove 0 for the purpose of guiding the sliding plate N which has feet or tongues W at its ends projecting into said groove. One of these plates is located at each end of the base and they are fixed in all positions to which they may be moved by means of a bolt P extending through slots V therein and provided with a thumb-nut R. Blocks T of substantially the same width as the boss K on the block J are located at the inner ends of the sliding plates N, and are provided with covers or cushions U, and upon these blocks the support is placed when it is to be adjusted, as shown by dotted lines in Figs. 2 and 4:. It will be seen that the blocks U may be moved longitudinally to vary the distance between them or their respective positions with reference to the block J to any desired extent, and this adjustment not only accommodates the device to arch supports of different sizes but permits the plate of the said support to be bent on any desired are and at any part.

The cam C is so formed that when the lever B is oscillated between its position in The block J has a boss Fig. 2 and its position in Fig. it forces the block J down or permits it to rise under the action of the springs H, and it is through this ram that pressure is applied to the plate of the support to etl ert the desired adjustment. The upper sur'tace oi the block J is curved to atl m'd a proper contact surface tor the. cam. and the recess of each boss G which receives the pin l) is open at the lH)tTt'()1ll**"2lS shown where the top of the standard A is cut away in Fig. Q so that the cam lever may be removed and used a, a mallet tor the purpose of bending the extreme outer edges of the plate, or conveniently placed for paclviing and shipping.

What I claim is 1. In a device of the character described the combination of a cam lever, suitable supports upon which said lever is mounted, comprising standards having recesses in their upper parts and openings leading from the said rcccs, at an angle thereto and projections on said lever adapted to engage said reces es, a vertically reciprocating block, a yrinp; for iolding said block nor mally in its upper position, the construction and arrangement ot the lever and block be ing such that the block is caused to descend by a movement of the lever, a plurality of sliding blocks located below the normal po sition of the first-named block and outside the plane of its reciprocation, and means for moving the said blocks.

2. In a device of the character described the combination of a cam lever, suitable supports upon, which said lever is mounted, comprising standturds having recesses in their upper parts and openings leadingitrom the said recesses at an ai'i rle thereto and projections on said lever adapted to engage said recesses, a vertically reciprocating block, a spring for holding said block normally in its upner position, the construction and arrangementof the lever and block being such that the block is caused to descend by a movement ot the lover, a plurality of slidingblocks located below the normal position ot the first-named block and outside the plane of its rcciproraition, means for moving the said blocks comprising plates on which saidbloclqs are mounted, a base, a slot in the said base, and projections on the said plates engaging said slot.
