Rod 21 is oppositely threaded to either side of the vertical center through shaft 12, whereupon rotation of rod 21 the arms will adjust rolls C and D towards or away from one another, depending upon the direction of rotation.

Although rolls 0 and D could be mounted and particular arrangement shown conveniently enables the support of means for simultaneously rotating bottom roll A and side rolls D and C. The bottom roll A and cages l9 and 20 are interconnected for simultaneous rotation. This is accomplished through a gear 35 fixed on shaft l2, which meshes with idlers 36 and 31 rotatably carried respectively by the radial arms l9 and 2!! which, in turn, mesh with gears 38 and 39 fixed on shafts l1 and I8, respectively. With this arrangement, when gear 35 is rotated in a counterclockwise direction to rotate bottom roll A in a counterclockwise direction, the motion will be transmitted to the cages through the idlers and gears to cause a similar rotation of rolls C and D. The shaft l2 may be rotated in any suitable way; in the embodiment shown there being provided a belt driven pulley 4B which is freely rotated on the. end of shaft l2- and'clutched into and out of engagement with shaft l2 as hereinafter explained.

There is further provided a top pressure roll B preferably arranged with its axis in vertical ali nment with the axis of roll A and is formed with a plurality of ridges 45 and grooves 46 in like manner thereto. In the mach ne shown, the grooves of the two pressure rolls are in alignment, although, if desired, they could be stabgered. The roll B is carried by a pivoted frame or carrier comprising a pair of arms 41 fixed to a rock shaft 48 journalled in brackets 49. The pressu e roll B is also adjustable to accommodate bats of various sizes; one of the supporting arms 47 being provided with a slot 5|) which receives a bolt 5! carried by one end of a lever 52, which lever is journalled on a rock shaft 48 and its other end connected to a yoke member 53. This yoke member is controlled for automatically raising and lowering roll B in timed relation to the starting and stopping of the machine. To accomplish this, there is provided a cam shaft 54 on which is mounted a cam 55 adapted to engage a roller 56 on the lower end of yoke member 53. On the outer endof cam shaft 54 there is carried a plate 5'1. having a stop 58 adapted to engage one end of a clutch operating arm 59. This clutch operating arm 59 is pivoted at 68 and is provided with a yoke 5! which engages a clutch sleeve 62 keyed to the transverse shaft l2. The outer end of the yoke arm 59 is provided with a suitable control handle 63. The cam shaft is rotated from shaft [2 through a belt 64 and suitable speed reducing means 65. The operation of the machine is as follows: The bats are rolled in the usual manner in a piece of burlap or fiannel that is, four to eight bats are laid one'upon the other on the flannel and rolled up from tip to brim. The rolled assembly is placed in the trough formed by the rolls A, C, and D, and, if necessary, rolls C and D may then'be adjusted by turning of hand wheel 30 'to properly space them for the size of the bat being manipulated. Roll B may likewise be properly adjusted by properly setting the bolt 5| in the slot 56 and then securing same in place. The clutch is now thrown in by the operating lever 63, whereupon shaft l2 will be rotated and the geartrain driven to simultaneously rotate rolls A, C, and D. The cam 55 will simultaneously move out of engagement with roll 56, whereupon roll B will be lowered into position on the top of the roll of bats E and frictionally driven by engagement therewith. After a predetermined time, cam 55 will engage roll 56 to lift roll B out of engagement with hat bats E and the stop 58 on member 51 will engage the inner end of clutch shaft 59 to throw the clutch out of engagement. The bats are then formed for anoher round.

During the operation of the machine, due to the pressure of roll B acting downwardly on the top of the roll E, it will be seen (Fig. 5) that the bat will be circumferentially corrugated by the top and bottom rolls A and B as part of the bat will be forced downwardly into the grooves of the roll A and upwardly into the grooves of the roll B. Simultaneously, the rolls C and D will produce longitudinal corrugations or flutes in the hat bat. As the bat E is rotated, the corrugations from the top and bottom rolls will be broken up by the flutes of the side rolls, and vice versa. In this way, the hat bats are subjected to a double action-that is, they are simultaneously manipulated both circumferentially and transversely. As there is a tendency on each round to reduce the size of the bat due to the manipulation which causes the felt or fur to interlock and harden. it is possible to finally adiust the side rolls after each round to take up for such reduction in the size of the bat. It will be seen that the action is extremely smooth, elastic. and

gentle. and avoids defective work. As the bat is simul aneously acted upon by the four rolls. it is subjected to considerable 'more manipulation than is accomplished when fewer than four rolls are util zed, and, as a result, the speed of maninu ation is considerably increased. Moreover.

as the bats are arranged in a substantially rectangular trough, it is impossible for them to work out of same.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made w t out departing from the scope thereof. it is intended that all matter contained in the above desc intion or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention which. as a matter of language, might be said to fall therebetween.

I claim as my inventionz 1. In a machine of the character described. a

bottom roll, a pair of side rolls arranged in. a

plane above said bottom roll and spaced apart to cooperate therewith to position a roll of bats. and a top roll above said other rolls adapted to exert pressure on the bats, said top and bottom rolls being circumferentially corrugated and said side pressure roll arranged above said other rolls and w oiroumferentially grooved similarly to said supporting roll.

3. ma machine of the character described, a transversely extending shaft, a bottom r011 mounted thereon, a pair of upwardly extending radial arms pivotally mounted on said shaft, the upper end of said arms extending beyond the periphery of the supporting roll, a shaft supported between the ends of said arms, aroll supported on said shaft, a gear supported on the end of said shaft, a second gear supported on the end of said longitudinal shaft, and an intermediate gear carried on saidradial arm interconnecting 5 said gears.
