Specication forming part of Letters Patent No. 15,570, dated August 19, 1856; Reissue No. 427, dated February 17', 1857 Reissue No. 933, dated March 27, 1860 Reissue N0. 2,257, dated May 29, 1866.

DIvIsIoN No. 1.

To all 'whom it may concern:

Be it known that WILLIAM OsBoRN, vof Louisville, in the county of Jefferson and State of Kentucky, did invent a certain new and useful. Improvement in the Manufacture of Bonnets, Bonnet-Frames, and similar articles to be worn upon the head; and that WILLIAM E. DOUBLEDAY, of Brooklyn, in the county of Kings and State of New York, and J oHN STEWART, of the city and State of New York, are the assignees of the entire right in said Letters Patent; and the following is hereby declared to be a full, clear, and exact description of the said invention.

Bonnets and similar articles had previous to the invention of said OSBORN been formed or shaped in detail. The tips and side bands composing' the crown had been separately stretched, formed, or shaped between heated dies, and the flaring facepiece had been formed separately in a similar manner, and afterward these separate parts were united at another operation, usually by a heated iron in the operators hands. Thus the making of bonnets, frames, or similar articles was accomplished by three operations: first, the making of the front or larin g face-piece or brim 5 second, the making of a tip and side band composing a crown 5 third, the joining by hand of the parts thus made separately in order to form a complete article.

Bonnets of straw and similar material had before been made by sewing the braids or pieces together, moistening and then pressing by means of an iron or by means of a die; if by the iron, the surface was passed over progressively; if by the die, only certain portions, and not the whole surface of the bonnet or similar article.

The nature of this division of the invention of the said OsBoRN consisted in manufacturing, stretching, or shaping, by means of heated ing by stretching, forming, or shaping by heated dies the flaring face-piece and side crown jointly at one operation, whether of one or more pieces of material, as distinguished from .the bonnets or frames in which these parts were made by separate operations and from the blocking of straw bonnets, in which the shape already given to the bonnet was xed or rendered permanent.

It will thus be seen that the said OsBORN, in the manufacture of bonnets and similar articles accomplished by the stretching or shaping and simultaneous pressing in one operation what had before required either three operations or the article to be specially shaped by sewing or otherwise previously, thus effecting a great saving in time and allowing of the use of dat or whole pieces of material, and saving the amount of such material in the lapping at the intersections of the several pieces.

In the drawing, a mechanism is represented for actuating said dies. Figure 5 is a perspec tive view of the dies and press.

Fig. 1, a a, a a a a, are heaters to be placed all around the side of the upper die. The small heater a' is the one that goes on the top of the upper die to heat the tip of said upper die. b b is the heater for the block or lower die.

Fig. 2, c and cl,'are front and `side views of the block or lower die. Fig. 3, No. I, e, is a round iron plate attached by screws j f f to lugs on the top of die J, No. II. The plate e has a bolt through the center and is attached by said bolt to a plate at the lower end of the rack-shaft. There are four screws through the plate attached to the lower end of the rackshaft to adjust the upper die, J. h is the top plate, attached by screws g g g to the top of the die J, forming the top of the same, to press the tip of the bonnet or bonnet-frame or similar article. Fig. 3, No. III, is atop view of the plate h and die J with heaters. No. IV is a side view, showing front and back of upper die, J. Fig. 4 is the case which covers the heaters of upper die, J.

By varying the shape of the dies the abovedescribed apparatus will press all kinds of bonnets and bonnet-frames or similar articles of every size and shape.

The block or lower die may be made of marble or any o'ther material. that will not rust from the acids which may be in the articles and diseolor them. The upper die may be made of cast-iron or other material, so arranged with a rim or iange around the lower edge as to hold heaters all around it, to make it hot enough to press the articles. The lower block or die stands upright on an iron bed-plate, and is secured by screws to keep it in place. The bonnet, bonnet-frame, or similar article is put upon the lower die and the upper die is lowered onto it by the crank or other mechanism, and it is pressed by one impression, or, in other words, is pressed all over at the same time. The bonnet, frame, or rsim/ilar article can be made either with the front or side crown in one piece, or in two pieces. If in two pieces they are both formed at once and stuck together at the sides and top at one impression, and in cases where the shape is such that the bonnet, frame, or similar article can be formed of one piece of material, including the flaring face-piece, side crown, and tip, the same can be pressed in the dies the same as bonnets. On the block or lower die there are two small steel pins about a quarter of an inch in length, made fast to said block. The pins have sharp points and stand vertically in the lower die. When the bonnet-frame is put on the lower die the pins stick through the corners of the material and holds the same in place until the tip and side crown are put on the lower die. The upper die is then lowered,

which upper die has two holes in it to receive the pins on the lower die, and at one impression the frame is made. The result is the same whether the front, side, crown, and tip are in one, two, or three pieces; it makes no difference with the machine; it works as well in the one case as in the other.

It will be evident that if a thin material is employed between dies that have originally been made for a thick quality of material the shaping will be equally effected by the material being stretched and held by the angular portions or lines of the dies without the dies acting upon the whole surface of the material.

The flaring face-piece and side crown formed at one operation, as aforesaid, may be employed with any desired character of tip, the forming of these parts at one operation never having been effected before the invention of the said OsBonN.

What is disclai1nedis,first, forming or shaping the tip and side crown or crown separately 5 second, forming the brim or daring face-piece separately.

What is claimed as the invention of the said OsBoRN is-'- 1. Manufacturing, stretching, or shaping by means of heated dies the whole of the bonnet (frame or similar article to be worn upon the head) at one operation, substantially as specified.

2. Manufacturing by stretching, forming, or shaping by heated dies the daring face-piece and side crown (of a bonnet or similar article to be worn upon the head) jointly at 011e oper ation, substantially as specified.

In witness whereof we have hereunto set our signatures this 27th day of March, 1866.
