IMPROVEMENT IN PATTERNS FOR CUTTING SHOES AND GAITERS,

Specification forming part of Letters Patent No. 37,527, dated January 27, 1863.

To aZZ whom it may concern,.-

Beit known that I, ELIAS SHOPBELL, of Ashland, in the county of Ashland and State of Ohio, have invented new and useful Improvements in Patterns for Cutting Shoes and Gaiters; and I do hereby declare that the following is a full and complete description of the construction and operation of the same, reference bein ghad to the accompanying drawings, making part of this specification, in which- Figure l is a top view of the vamp-pattern, not extended. Fig. 2 is a top view of the saine when extended. Fig. 3 is an edge view of the same. Fig. 4 is a top view of the quarter, not extended. Fig. 5 is a top view of the same when extended, and Fig. Gis an edge view of the same.

My invention relates to such a construction of the pattern, both for the vamp and quarter, that there shall be a corresponding` proportional extension in each that will harmonize with each other upon the scale of sizes from one to eight, or higher, upon each, the extension not being upon a simple ratio, butin constantlyvarying proportions, by means of slots running at various angles from a base-line, as hereinafter specified.

I will in the first place describe the pattern for the vamp, Figs. 1,2, and 3. This consists of five plates, the forms of each being shown in the figures, one of which, A, is the center plate, the others, B B C C', being in pairs and secured together by slots and headed pins.

The plates B B are in all respects duplicates of each other, except they are in reversed position. At the forward end of the plates B Bl are slots D D', which work upon pins d d in the plate A. rlhe angle of these and the other slots are measured in the extended pattern from the base-line m w. The angle of the slots D Dl is outward and backward eighty-two degrees. At the back end of the same plates are situated the slots E E', having an angle backward and outward of eighty degrees. They work upon the pins e e in the plates A B.

The slots E Ef" in the plates O O incline forward and inward atan angle of twenty-five degrees, and have their pins in the plates B B at e 6". The slots F F are situated at the middle and back part, where the plates lap over each other. Their angle is forward and outward eighteen degrees, and they work upon the thumb-screw F in the plate A. Forward of these are situated the slots G G. These have an angle forward and outward of seven degrees, and work upon the pin g in plate A. The plates C C are pivoted together near the forward end, as seen at c, forming thereby an articulation. The thumb-screw F" holds the several plates in any desired position upon the scale of sizes H, for all the plates move in concert. In consequence of these several angles to the slots and the points of attachnient for the pins, this pattern, when ext-ended, increases more rapidly in width from J to J than it does in length upon the line fr, and that in an increasing ratio.

The pattern for the quarter, Figs. 4, 5, and 6,is also composed of veplates, none of which are in pairs. K is the foundation-plate, to which the others are secured by means of slots and pins. The plate K has upon it a scale of sizes, H correspondin g to the scale Hin Fig. 2.

The angles of the slots are marked upon the extended pattern, in their relation to the line a".

The plate L has three slots. That seen at M is parallel with the base line, and works upon the pin m in the plate P. The slots M IVI have their angles forward and downward at an angle of sixty-tive degrees, and work upon the pins m m in the lower corners ot' the plate K.

The plate N has four slots. N is situated at the upper portion of the plate, and has an angle downward and forward seventeen degrees, and works upon a pin in plate K. The slot N" has its angle upward and forward at sixty-ve degrees, and works upon the pin n in the plate L. The slot NI has an angle down ard and forward at twenty-two degrees, and works upon the pin m in plate K. The slot o has an angle forward and downward at twenty-six degrees, and works upon the thumb screw o in the plate K.

The plate P forms the lower angle of the heel. Its slot Pl inclines downward and backward at an angle of fifty-two degrees. The slot P has the same angle and works upon the thumb-screw o. y

The heel-plate Q has a slot, R, at its upper end, having an angle downward and backward of twenty-four degrees, and works on a pin in the plate K. The slot R has an angle downward and backward of twenty-three degrees, and works on the pin m. The slot R is near the center of the plate Q, and has its angle upward and backward eighty-five degrecs, and moves on the pin o in the plate P, the plate K being cut away to make room for the head of the pin. In consequence of the various angles of these slots and their attachments to the other plates, the extension of the pattern is proportional to that of the vamp, the saine number on each scale making the patterns to correspond.

A distinguishing feature in my vamp-pattern isthe pivoting together the plates C C at the toe, in consequence ot' which the eX-A pansion of the pattern is made to conform in all its proportions tothe quarter-pattern.

I am aware that extension patterns have been constructed; but all those which have sire to secure by Letters Patent, is-

The vamp-pattern, with its articulation cY and the-several slots governing the simultaneous and proportional extension of the pairs ot' plates B B C C', constructed as herein specified, in combination with the quarter-patf tern, constructed as described, and having a j corresponding and simultaneous proportional y extension corresponding to that of the vamppattern, as herein set forth.
