CHARLES E. SACKETT, OF DANBURY, CONNECTICUT.

HAT-BRIM PRESS TO FORM WELT EDGES.

Application filed April 27, 1908.

'1 0 alt whom it may concern:

Be it known that I, CHARLES E. SACKETT, a citizen of the United States, residing at the city of Danbury, in the county of Fairfield and State of Connecticut, have invented new and useful Improvements in Hat-Brim Presses to Form Welt Edges, of which the following is a specification.

This invention relates to a mechanism for reinforcing the edge of a hatbrim by doubling the felt back upon itself to form a welt,-a style now coming into use, and already adopted in the hat for the United States Army. Heretofore the practice in general use for performing this operation has been to first form a reverse curl in the hatbrim edge by means of a curling machine, then to insert a matrix plate within the curl, then by hand labor with a heated iron to press the curl fiat upon the upper side of the matrix, and then with a hatters rounding ack to cut away the surplus brim, leaving an even width of reversed welt to be stitched down.

The object of my invention is to do away with the severe labor of hand ironing, and the expert use of a rounding jack, and to provide a quicker and better mechanical substitute, as well as to introduce other needed improvements in the art.

In the accompanying drawings, like numerals relate to like parts.

Figure 1, 1s a side elevation showing the press closed. Fig. 2, is a front elevation in central lateral cross section showing the press open. Fig. 3, is a plan view of Fig. 1. Fig. a, is a portional section three-fourths full size, showing the action of pressing, trimming and punching.

1, is a suitable table. 2, a raised elliptical platform which may be cast with the table top or bolted to it, the periphery 3, of the platform is made to conform with the shape of the desired hatbrim; in the center of the platform is a recess at, the edge 5, of which is made to conform with the outside shape of the crown of the hat so that when the crown is placed in the recess the brim edge necessarily conforms to the edge of the raised platform, (see Figs. 3 and 4).

6, is a movable press platen having a depending flange 6, with an inner elliptical face corresponding accurately with the periphery of the platform 2, so as to closely surround it upon its descent. To allow for any variation of movement the inner ellip- Specification of Letters Patent.

tical face of the flange is tapered as at 7, to a sufiicient extent to insure certainty of entry around the platform 2, and then contracts to the vertical face 8, accurately fitting it, and which face confines and shapes the edge of the hatbrim (see Fig. 4). At

right angles to face 8, is the horizontal face 9, of the exact width of the desired reversed Welt, this face constitutes the press platen proper, and the pressure is exerted on it only, if a square outer edge is desired on the hatbrim, the faces 8 and 9 form a sharp right angle, if a rounded edge is desired, the corner 10, is rounded, (see Fig. 4,) or these two faces in conjunction may be molded to give any desired shape to the welt edge.

In order to trim off the surplus brim extending beyond the desired width of welt, I attach to the vertical inner elliptical face 11, of the descending platen, a thin elliptical knife-blade 12, whose edge extends below the platen face 9, the usual thickness of the hatbrim felt. This blade is secured to the platen by screws 13, at proper intervals, and is also held in position by forming a projecting edge 14, above it.

On each side of the movable platen are cast lugs 15, which are bolted to overhead lugs 16, projecting from the side-boxes 17; these boxes slide upon vertical guide-rods 18, which are securely bedded in the table and are connected at their top ends by the stay-bar 19; the boxes are provided with outer bearings 20, from which depend connecting bars 21, which are journaled at their lower end upon bearings 22, secured in one end of the cranks 23, the other crank end being rigidly attached to the working shaft 24:; this shaft is ournaled in boxes 25, which are bolted to the table sides at 26. The shaft is worked by the lever 27, rigidly attached to it, about the central portion of the shaft is secured the arm 28 (see Fig. 2), which carries the weight 28, which balances in its downward movement all the rising weight of the press platen and its parts, thus leaving the operator only the work of movement and of exerting final pressure with the lever. To get the greatest pressure at the final point the lever is attached to the shaft at right angles to the cranks (see Fig. 1), thus bringing the fulcrum and connecting bar bearings nearly in vertical line as shown in Fig. 1; they can be brought quite in line by curving the connecting bars and placing the shaft 24, and boxes 25, midway of the machine; by this means the press locks itself when under pressure and retains it until the lever is again moved.

It is necessary to heat the movable platen in order that it shall soften and remold the stiffening material in the hatbrim, to this end the platen is recessed on its outer face at 29 (see Fig. l), to receive the encircling gas pipe 30, which is perforated at suitable distances with burner holes, and is connected by fitting 32, with flexible gas and air tubes 33, 34, which rise and fall with the platen. Owing to the necessity to heat the platen the heat draws the temper from the circular knife 12, preventing its carrying a keen enough edge to entirely always cut the surplus brim rounding clear, but it always cuts a deep and true score, and by running the point of a hard knife around the score line, the rounding is removed, the matrix-plate prevents cutting into the hatbrim, and any unskilled labor can accomplish what now re quires skilled labor.

In some styles of hats with welt edges, notably the U. S. Army hat, eyelet holes are required 011 each side of the brim, located centrally adjacent to the crown, to receive a chin cord; these holes are now put in by using a hand punch and mallet. In this invention they are put in automatically and simultaneously with the formation of the welt by a construction consisting of a bridge casting 35 (see Figs. 2 and 4), which crosses the open space of the press platen centrally, and is provided at suitable points with two steel punches 36, 37, projected a sufficient distance below the bridge and platen face to pierce the hatbrim. The stationary platform 2, is provided with holes 38, 39 to receive the punch ends and dispose of the punchings, the bridge casting at its ends is continued upward to form lugs 40, which are bolted to the under side of the lugs 16, continued out from the boxes for that purpose. The bridge and punches are remov able when eyelet holes are not required.

In Fig. 4 is shown by the heavy black line 41, the material or felt constituting a portion of a hatbrim and crown in the act of having the welt edge pressed and trimmed and the brim holes punched; the matrix is also here shown, which consists of a short hat-block 42, which is adapted to fit in the crown of the hat 43, and which is attached to a thin matrixplate of zinc or copper 44, of the eXact size of the brim, less the thickness of the material. It is obvious that when this matrix is inserted in the hat-crown with the plate within the curl of the brim, and the hat is dropped in the central recess 4, of the stationary platform 2, and the platen brought down upon it by means of the lever 27, the operation herein described will be performed by the operator in one single movement.

This machine is not designed to perform the operation of curling the edge of a hat brim, the hats come to the machine with the brims already curled, this machine is designed to press the curls into a flattened welt, and a different machine is required for each different size of hat.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:
