CHARLES E. SAOKETT, OF DANBURY, CONNECTICUT.

HAT-BRIM PRESS TO FORM WELT EDGES.

Application filed July 9, 1908.

To all whom it may concern:

Be it known that 1, CHARLES E. SAOKETT, a citizen of the United States, residing at Danbury, in the county of Fairfield and State of Connecticut, have invented a new and useful Improvement 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 hat brim by doubling the felt back upon itself to form a welt.

On the 27th day of April, 1908, I filed Serial Application No. 429,425 for an invention having the same title and purpose. That invention related to a machine adapted to form the welt edge 011 only one size of hat and was operated by hand. On the 6th day of June, 1908, I filed Serial Application No. 427,201, for an invention having the same title and purpose. That invention related to a machine adapted to form the welt edge on various sizes of hats by grouping various sizes of hat brim presses in one frame and in operating them serially and automatically by power. It also provided for removing the surplus felt rounding after the welt was formed by means of an internal. rounding jack instead of a direct circular cutter.

The object of this invention is to still further improve upon the two preceding inventions by constructing a machine to occupy less floor space, cost less to construct and heat, and. yet be adapted to manufacture welt edges on all sizes of hats also to improve the internal rounding jack, and eyelet punches. I accomplish this purpose by using a single frame of the construction shown in Soriai Application No. 429,425, and by supplying a plurality of interchangeable press parts, each adapted to a single size of hat, and which are made capable of substitution, upon the frame together with an improved rounding jack and adjustable eyelet punches. In Serial Application No. 429,425, the press parts were not interchangeable, but were an integral part of the machine, a different machine being required for every size of hat.

In the accompanying five sheets of drawings, I show both the old construction and the new.

sectional view on an enlarged scale of the improved rounding jack and eyelet punches mounted u on an interchangeable press head, the w ole construction being capable of substitution, as shown in Fig. 3. Fig. 5. is a detail view of the pivoted knife head of the rounding jack. Fig. 6. is a plan view on an enlarged scale of the permanent frame above the table top, the interchangeable press head and floor being removed. Fig. 7. shows a side elevation of the same, an interchangeable press head and press floor being ready to drop into position on theframe. Fig. 8, on Sheet 1. is a detail sectional view of the permanent ring, and permanent heating pipe. Fig. 9. is a plan view of the upper side of an interchangeable substitute press floor. Figs. 10, 11, and 12, show interchangeable substitute press floors of varying sizes, in elevation. Fig. 13, one in section on line A, the internal dotted lines B, show the mutual position and alinement of the dowel pins, the external dotted lines 0, show the difference in diameters. Fig. 14. is a plan view of the upper side of an interchangeable substitute press head. Figs. 15 and 16, show interchangeable substitute press heads of varying sizes, in elevation.

ig. 17, one, in section on line A, the exter nal dotted lines D, show the mutual diameter and alinement of the projecting flanges, the dotted line E, the alinement of the bolt holes, the dotted line F, the varyingdiameters of the press head proper.

In Figs. 1, 2, 3, and 4, the rounding and punching mechanism is shown as mounted u on and secured to one of the interchangea le substitute press heads, in all the other figures it is temporarily removed for convenience in illustration.

In all the drawings like numerals relate to like parts.

1. is a suitable machine frame, supporting a table top 2; from the table rises an elliptical vertical section 3, which may be cast with the table or bolted to it (see Figs. 5 and 7). It is perforated at suitable points by holes 4, adapted to receive the dowel pins 5, arranged at corresponding points below the interchangeable press floor 6. This press floor is of an elliptical plan, its peri hery being of the same shape as some one o the various sizes of hat brims. It has an elliptical opening 7, in its center, which corresponds to the crown of a hat of similar size (see Fig. 3). The peripheries and crown openings of the various interchangeable press floors all vary by one eighth of an inch increased diameter, from hat size 6 to 7%, requiring twelve interchangeable floors to cover the ordinary range of hat sizes; although the floors vary in their elliptical diameters, the dowel pins 5, all have their centers in the same ellipse which corresponds to the holes in the permanent raised table section upon which the floors are supported, thus any of the press floors may be dropped temporarily upon the table top and become a component part of a complete machine.

Rising above the table top and supported by the frame are guide posts 8, which ass through boxes 9, (see Figs. 6 and 7). T ese boxes form part of or are securely attached to a substantial ring 10, having a smooth upper face in which are bedded at suitable positions the upright bolts 11, outside of the oxes, and forming part of them are journal arms 12; to these are journaled the depending side bars 13, (see Figs. 1, 2, 3), having their lower ends journaled to the extremities of crank arms 14, which project from and are secured to the shaft 15, having at one end an operating lever 16, and at the other end a lever 17, carrying a balancing weight 18, the connecting side bars 13, are curved, so that the center of their end bearings will come in a vertical line with the fulcrum centers of the cranks and lever, when the cranks are at the end of their vertical throw. It is evident the movement of the lever will cause the ring 10, to rise and fall, and that the weighted lever will balance the moving parts and sustain the ring when it is raised, or any weight it may carry. This ring supports the interchangeable press heads 19, (see Figs. 3, 4 and 7), which consists of a substantial elliptical flanged ring having a sectional shape as shown in sectional Fig. 4. They have a vertical inner elliptical face 20, joined to a horizontal face 21, which form the ed e and surface ressing faces of the welt, the face 21 being 0' the same width as the desired welt edge; rising vertically from this face is the inner elliptical vertical face 22, against which revolves the cutting knife 23 for removing the surplus felt rounding; the vertical face 20 is continued downward in a conical outward slope 50, to afford easy entrance of a ress floor within the corresponding ress ead; the upper surface of t e press ead has a projecting flange 24 (see Figs. 5 and 7) which is continued out to form a seat upon the movable ring 10. At suitable points 25, the flange is swelled and perforated by bolt holes, which drop over the bolts 11, bedded in the ring 10 and to which the interchangeable press heads are secured by nuts and Some hats, notably the become a component part of a complete machine.

Crossing the upper face of the interchangeable press heads, and bolted to them as sl own at 27, is the bridge casting 28 (see Fig. 3 and sectional Fig. 4), constructed with a central upright section which is drilled to receive the upright shaft 29 and recessed to receive the spring 30, surrounding the shaft; at the upper end of the shaft is secured the handle arm 31, against which the spring bears to support it at the lower end of the shaft is secured or made part of it, the revolving arm 32 which carries at its extremity the knife 23, bearing against the inner vertical face of the press head; this revolving arm is drilled to receive the horizontal shaft 33, and recessed to receive the spring 84, surrounding the shaft, both spring and shaft are adapted to hold the knife always pressed against the vertical face of the press head by the construction shown in sectional Fig. 4. It has been found that in traveling around the inner face of an ellipse a knife rigidly attached to a revolving flexible arm will not always bear true against the face of the ellipse. To obviate this deviation, I show in Fig. 5 an enlarged View of the knife head used; the head 35, in which the knife 23 is clamped by the clamp bolt 36, is made separately, and is ivoted to the end of the horizontally flexible arm by the pivot 37 it is recessed as shown by the dotted lines to allow of a slight pivotal movement which is balanced by the opposite extremity of the knife head; with this movement the knife follows the elliptical inner face of the press head accuratel The spring 30, supports the knife point e ear of the felt until it is desired to cut the rounding, when pressure upon, and revolution of, the handle erforms the work.

%1 S; Army hat, require their brims punched with eyelet holes. To meet this requlrement the press floors are provided with unch sockets 49, arranged at each side of tie crown o ening to receive the points of eyelet pun'c es 38, arranged above them; see Figs. 9 and '13, though indicated, these sockets are not visible in any of the other figures. In order to allowa free movement for the revolving arm below the supporting bridge the eyelet punches 38, must be suspended clear of it, this is done by constructing columns 39, as part of the bridge casting and drilling them to receive the punch shafts 40, which terminate at their u per end in punch heads 41. Beneath tiese heads are springs 42, surrounding the columns, which, when the unches are pressed down by the hand, raise the punch points 38, again clear of the revolving arm.

It is to be noted that the bridge casting 28, carrying the revolving knife mechanism, and also the eyelet punches, is secured to the interchangeable press heads as shown in Figs. 3 and 4, consequently each substitute press head carries its own knife rounding mechanism and punches, and is a complete and independent structure in itself the press heads and press floors are arranged in pairs, consequently when a substitution of one hat size for another is desired on the machine, sim ,ly changing a head and floor carries with. it al the mechanism necessary to finish the hat brim, and a change from one size to another is quickly effected.

For the purpose of heating the permanent ring 10, which is a flanged casting as shown in Fig. 8, a pipe 43, is carried around the ring supported on brackets 44, projecting from it. The pipe and brackets being beneath the flange, and behind the ring, do not show in any of the other figures. The pipe is p-rforated at suitable distances with burner openings 45, and is fed with gas and air by means of pipe elbow 46, and connections 47 and 48, supplying gas and air by means of flexible tubes connected to convenient supply pipes; the flexible tubes allow the permanent ring to rise and fall as stated, while the heat is always ready to heat any of the interchangeable press heads when placed in position within the permanent ring which supports them.

Various changes in detail might be made in the method of constructing or securing the inter hangeable press heads or floors to the permanent frame, without departing from the principles of my invention.

I do not limit myself as to the details, and
