To all whom t may concern:

- Be it known that I, C. O. PARMENTER, of Amherst, in the county of Hampshire and State of Massachusetts, have invented a new and Improved Machine for Forming Hatsand Bonnets from Palm-Leaf or other Fabrics; and I do hereby declare that the-following is a full, clear, and exaet description-of the same, reference being had to 'the accompanying drawings, making a part of this specification,

Figure l is a vertical central section of my invention, takenin the lineof Fig. 2. Fig. 2 is a transverse section of the same taken in the line y y of Fig. 1. Fig. 3 is a top view of a hat.

Similar letters of reference indicate corresponding parts in the several figures.

To enable others skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents 4the foundation or bed ofthe machine, which has secured in its back end an upright B, from the front side of which, at a convenient height from the bed to form a table for a person to work at, project horizontally two arms C C, which are supported about midway of their length by uprights o o., se-

l cured at bottom in the bed A.

The hat-block or former J is ofl metal and of oval form in its horizontal section, and rests near each extremity of its major axis upon the arms C C. The upper surface of the hatblock or former J is made to correspond with the sha-pe of the hat or bon net desired to be produced.

D and E represent, respectively, the upper and lower halves of the clamps, which have an opening in the center to correspond with the size and shape of the hat-block in its horizontal section, and the lower one of which, when in its lowest position, fits over the hatblock and rests upon the arms C C. The upper surface of the lower half of the clamp on either side of the openingis of convex form,

to correspond with the curvature of the brim of the hat, and the under surface of the upper half of the clamp is hollowed out to fit the convexity of the lower half, so that the two can be brought close together to clamp the fabric between them equally on all sides of the opening. rheupprhaifpfth Giampisattached at opposite ends of its majoraxis tothe extremities of the vsliding barst b, which are -itted to move up and-down lbetween vertical guides (not shown' in'tl1 e ilrawings) attached on opposite sides of thefuprightsl" The lower ends of these sliding barsfare 'eachfprovided with a laterally-projecting pin d, 4which pins connect the sliding bars b b with the treadle K, by means of which motion is ilnparted through the sliding bars to operate the clamps D E. The lower half E of the clamp in' its outer diameter' is madev somewhat smaller than thel upperI 'half and concentric therewith, and is attachedto the extremities -of the sliding bars e e, which move up and down between vertical vguides ff, attachedonv opposite sides of thev uprights 'and projecting inwardly. These` bars are connected together.

at their lower ends by a crossbar F, which is suspended by cords m, passing over grooved pulleys depending from the arms C and having a weight N attached to the opposite ends for the purpose of causing the lower half E of the clamp to return to its normal position after the process of forming Va hat is performed, and also for causing it to exert a pressure upon the upper half D to clamp the fabric between them while the hat is being formed. l

H is the annular-flanged stretcher secured upon the end of the spindle L, which is of rectangular form for about one-half of its length from the top down, which square portion is nicely iitted inahole in the projection M, which allows the spindle and stretcher to move up and down and prevents any rotary movement of the same. The part of the spindle adjacent to the square shoulder has a screw-thread o formed on it, which fits a corresponding screW-thread in the hand-Wheel I. This hand-wheel is kept in contact with the under side of the projection by a forked bracket, the forked portion of which partly surrounds the hub of the hand-wheel and supports it in position by a collar secured on the end of the hub above the prongs of the fork. The spindle with the annular stretcher H is suspended fromv the ceiliug'or from a cross-tree by a cord g, which passes over loose pulleys 7L fz', and has aweightj attached at its Opposite. end fer the purpose ef elevating the t Stretcher .entef the Weywnen net ,use te forni the crown of the hat.`

The operation is as follows: The machine being in the position shown in 'Fgflgthe Sheet er Sheets .of pelin-leef or .other .fabnie from which the 1iaer-bomietis t be formed are placed between the clamps and the upper half Dbrought downnponthe lower half E by pressureof the foot on thetreatdle, cltmping the fabric between them, when by a still greater pressure the oltplpsdeeend together, t

allowing the fabric ttsP they descend lto'g'trdllally'draw through them, and when in their A lowest position to be `tigglrtly ns'tretel'ied. ,OYr
