Abstract: 25,506. Turner, H. H., Turner, A., and Turner, A. Dec. 23. Felt hats.-Relates to felt-hat crown pouncing machines of the type described in Specification No. 17,190, A.D. 1897, and has for its object to enable two hats of the same or different size or shape to be pounced simultaneously, and in such a manner as to cause one hat to act as a guide or pattern for the other hat for the two pads to operate in unison. A further object is to impart variable speed to the hat body, quicker while the pad acts upon the two sides of the hat, and slower while it acts upon the front and rear sides of the hat, and to revolve the hat at an even speed when the pads are acting on the " square " or "tip" " of the hat. Fig. 1 shows a side elevation of the machine, Fig. 2 a plan, and Fig. 4 a vertical section of the head portion. The column B and its interior shaft are arranged as described in the prior Specification, so that the hat blocks D are rapidly revolved, while the head C carrying the hat blocks is slowly rotated so as to expose all the parts of the crowns in succession to the action of the pads L. The pouncing-staffs K and pads L are operated in the same manner as that described in the prior Specification. The two pouncing- staffs, or the carrier lever arms which support them, are coupled by adjustable connecting-devices Q to the radial arms R of a collar R<x>, which is loose on the pillar B. The arms R are of equal length or radius, and the connections S of an equal length or of such a length as to cause the two pads to lie at the start in contact with the hats ; the operation of one pad as it pounces the hat on one block is the same as the operation of the other pad. The hat blocks D are mounted on the ends of a shaft C<x>, Fig. 4, which receives its motion from a cup bevel-wheel F, through the bevel-wheel G, shaft J, eccentric spur-wheels H, H<x>, plain circular spur-wheels I, I<x>, and wheels E<x>. The wheels H<x> and I are fast upon the shafts J, J<x>, and the wheel I is adapted to slide endwise. The wheels H, I<x> are loose on the shafts J, J<x>. On the face of the wheel I is a pin I<xx>, Figs. 4, and 4<a>, which normally projects into a hole in the wheel H. In the wheel I<x> is a segmental opening I<xx> <x> into which the key of the wheel H <x> projects, and the two are held in engagement by the spring J <x> <x>. The variable speed is obtained when the wheels I, H are in engagement, the wheel I<x> running idle, and its variable speed being allowed for by the slot I<x><x><x>. This variable speed only lasts while the sides and ends of the hat are being operated upon, and, when the pads come to operate upon the top of the hat, a lever T, automatically operated by a curved abutment on the rotating head C, moves the wheel I out of engagement with the wheel H, and the shaft is driven at an even speed through the wheels I, I<x>, H<x>. Fig. 5 shows a modified form of pouncing-pad, consisting of an endless pouncing- band Y carried by an arm Y<x> which has a radial movement only and carries a set of axes over which the band Y may travel, and also a pulley Y<x><x> by which and a strap, flexible shaft, or other driving-medium the band may be rapidly rotated. A rubber roller Z supports the band Y at the point where it presses against the hat.
