IMPROVEMENT IN MACHINES FOR STRETCHING HAT-BODlElS. M

Specification forming part of Letters Patent No. 165,400, dated July 6, 1875; application filed october 31, 1874.`

To all whom it may concern:

Beit known that I, GEORGE YULE, of the city` of Newark, county of Essex and State of New Jersey, have invented certain new and" useful Improvements in Machines for `Stretching Hat-Bodies; and I do hereby declare that the following is a full, clear, and exact description thereof, sufficient to enable others skilled in the art to whichmy invention appertains to make and use the same, reference being had to the accompanying drawings, and to the letters ot' reference marked thereon, and which form a part of this specification, in which- Figure l is a top or plan view of my invention. Fig. 2 is an end view of the same, and Fig. 3 is a detail view.

Similar letters of reference occurring on the several iigures indicate like parts.

My invention consists ot' a machine for stretching the conical caps of felted material ot' which hat-bodies are made previous to forming them upon the proper blocks, and of which .the construction and operation will hereinafter be more fully shown and described.

Referring to the drawings, A represents the frame or body of the machine, having a tank or vat, B, situated in the upper central part of the same, said tank or Vat being provided at its bottom with a coiled pipe, C, perforated on its upper surface. Through the lower central part ot' the frame A is placed la horizontal shaft, D, as shown in dotted lines in Fig. l, In one end of the frame A is also arranged a vertical rod, E, the upper end of which is provided with a cone-shapedhead, d, and the lower end furnished with screw-threads, adapted to work in the screw-threads of the adjusting-wheel F. The vertical rod E is given a reciprocating motion by the action of Jthe crank-pin c, arranged ou the wheel G, which is secured to the inner end of the horizontal shaft D; said `crank-pin e engaging with the sliding block r, arranged to work in the slotted opening of the larm g, attached to the lower part of the adjusting-wheel F. On the upper part or" the frame A, and near one end, is arranged a stailiona-ry disk, f, around the periphery of which are secured lugs JL, to which' are `pivoted the radiating stretcher-arms a, as shown in Fig. 3.

AThese arms are provided with elbows j,

f rod, L, arranged in suitable bearings, and provided with the treadle o, is attached to the end of the machine; said rod having a lug or pin, p, secured to its upper end, which engages in the slot a ofthe sliding block K; the radiating arms a and b being held in a closed position, when the machine is not being operated, by means ot' the rubber band or suitable spring c. (Shown in Figs. 2 and 3.)

In the operation of the hereinbefore-described parts, the hat-body, consist-ing of a conical cap otIl felted material, is rst placed in the tank B, which is partially filled with hot water, and steam introduced into the same through the perforations in steam-coil pipe C, the steam being ejected into the water, and, coming in contact with the felted material, renders the same pliable and soft. The hatbody is then taken out, and drawn over the stretcher-arms a while-in the position shown in Figs. l and 2. The shaft VD is then set in motion by suitable power, which gives a reciprocatin g motion to the vertical rod E, the coneshaped head d of which, in its upward passage, spreads the arms a., as shown in Fig. 3. The'treadle o is now pressed down, which forces the sliding arms b to the upper part ot' the arms a, and on a level with the saine, as shown in dotted lines in Fig. 2, in the open ation of which the hat-bodywill readily and thoroughly acquire the requisite shape.

The usual plan of stretching felted hatbodies upon the forming-blocks by hand is an operation requiring tedious manipulation on the part of the workman but by the employment of the above-described machine they mayl be quickly and thoroughly stretched previous to being formed upon the proper blocks.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the expansive hinged stretcher-arms a and sliding hinged stretchers or formers b with the vertical-actin g shaft E, provided with a head, d, substantially as set forth.

2. The combination-of the expansive stretchers and formers a and b, and the vertical shaft E, provided with an enlargement or heath-and the adjusting device, consisting of a right and left thread and nut, substantially as and for the purposes set forth.

lhave hereunto signed my name before two subscribing witnesses on this the 25th day of June, A. D. 1874.

GEORGE YULE. Witnesses:

JOHN DANE, Jr., J oHN JACOB YUHL.
