MACHINE FOR BLOCKING HATS.

SPECIFICATION forming part of Letters Patent No. 355,254, dated December 28, 1886.

(No model.)

To all whom it may concern:

Be it known that I, AARON T. CLARK, of the city of Yonkers, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Machines forBlockings Hats; and I declare the following to be a full, clear, and exact description of the invention, when taken in con nection with the drawings which accompany and form part of this specification.

The ordinary method of blocking hats for finishing consists in holding the hat over a steam-pot until it is heated, then drawing it down over the block by hand, drawing down a portion of the body at a time, following it down by a cord drawn tightly around the out- I side of the hat, which cord is forced down by a runner down in the-hand of the hatter until the hat is forced onto the block and adapts itself to its shape. There are numerous objections to this method, principal among which is the fact that the steam on emerging from the pot is exposed to the air, which partially condenses it, and thus it very imperfectly performsits work of heating the hat; also, when the hat is drawn down over the block, five or six pulls are often required to draw it down. In doing this each pull is applied to only onesixth of the circumference, and if the hat fits the block very tightly, or if there is any imperfection in the body, the result is, that the hat is torn and made worthless.

The object of this invention is to provide means whereby steam at a high temperature and free from moisture is continuously applied to the hat to heat it, and also means by which the strain on the hat-body is equalized. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 shows a front view of the machine, one of the compartments being shown in section; Fig. 2, a transverse section of a compartment, and Fig. 3 a plan.

The apparatus consists of an oblong box, A, which box may be set on legs at a convenient height, and which is divided into compartments. In each compartment is an ordinary steam-box, B, which is filled with pebbles, and is supplied with steam through pipe I).

a is an opening in lower halfof compartment to allow escape of steam.

O C O are hinged covers having oval openings corresponding with similar openings in top of box A.

E E E are levers having universal hinges e e e, which permit the levers to be so moved about that the knob or projection 6 can be moved to any part of the oval opening in cover (3.

F F'are posts supporting rail F, against which the covers and levers may be leaned.

The operation is as follows: Thelever Eand cover 0 being thrown back, a hat, D, is inserted in the opening and the cover lowered and fastened by button 0, thus keeping the brim flattened. A block is then put in the hat and the steam turned on pot B. The steam, rising through burlap cover I) and burlap b, enters the confined space If in a very dry state, and being thus closely confined retains its heat, and is in a condition to quickly and thoroughly do its work of heating the hat-body D. When this is accomplished,the leverEis lowered until the knob e touches the top of block in bat D, when pressure is applied to force the block down into the hat-body. The lever E being movablelaterail'y and longitudinally, the pressure may be applied to any part of the block desired, the result being that a uniform strain is applied to the hat-body without danger of tearing it.

Agreat saving of time is also effected by this mechanism, as by the hand method the hat requires to be steamed each time it is pulled down on the block, and being removed from the steam soon becomes cool; but in this device the hat-crown is surrounded by steam during the time the pressure is applied.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, isv 1. In a machine for blocking hats, the combination, with a steam-pot covered with por- 0118 material, of a separate inelosed steama universal-hinged lever having a projection chamber, in which the hat is inserted for heatwhich can be moved to any part; of the opening, substantially as described. ing, substantially as described.
