Specification of Letters Patent.

Patented Sept. 1, 1908.

Application filed November 12, 1906. Serial No. 342,946.

To all whom it may concern:

Be it known that I, PAUL L. BROCKAR-DT, a citizen of the United States, residing at Hamilton, Ohio, have invented a new and useful Improvement inHangles, of which the fol lowing is a specification. A

My invention relates to man 'les of the class wherein the linen is carried between an endless apron and a cylindrical drier under a series of pressure rolls, and the objects of my improvement are to provide means for utilizing a greater or less number of pressure rolls; to move and maintain any or all of the rolls toward or from the drier; to adjust the pressure of the rolls independently of their shifting mechanism, and. to provide simple and durable construction together with facility of adjustment and efficiency of action. These objects are attained in the following described manner as illustrated in the accompanying drawings, in which Figure 1 is a transverse vertical section on the line a-a of Fig. 3 of a mangle embodying my improvements; Fig. 2 an end supporting frame with the roll shifting mechanism in operative position; Fig. 3, a longitudinal section on the line bb of Fig. 2 of one end portion of the mangle, Figs. 4 and 5, respective front and side elevations with parts in section of an adjustable bearing for the pressure rolls. Fig. 6' an elevation of one of the brackets, andFig. 7 an elevation of a housing adapted to slide therein.

In the drawings, 1 re resents the end supportin frames, 2 a ho ow cylindrical drier forme with hollow journals 3 whereby it is journaled therein. A driven gear 4 is secured on one of the journals for rotatingthe drier in the direction of the arrow. An endless apron 5 partially encircles the drier in contact with its-face and travels in the direction of the arrows.

6 and 7 represent the respective front and rear and 8, 9, 10, and 11, the intermediate padded apron pressure rolls some or all of which may be provided with respectire pinions 20 in mesh with gear 4. Said pressure rolls are capable of being moved equal distances toward or from the axis of the cylindrical drier in a radial direction.

12, 13, 14, and 15 represent the apron rolls, 16 the stretcher roll, and 19 the ductor bar, all constructed and arranged in the ordinary manner.

A series of brackets 28 are adjustably bolted to each of the supporting frames and provided with grooves 27 and with slots 29 and 30. Housings 23 mounted to slide within the respective brackets and in lines radiating from the axis of the drier are each pl'OVldGd with a slot 22 in registration with the'corresponding slots 29, with a radial bar 38 movable through slot 30 and with a compression spring 24 which is adjustable by means of a hand screw 25. Bearings 21 wherein the pressure rolls are j ournaled are supported within the housings and maintained in con tact with the bottom of slots 22 therein and under a yielding pressure by means of springs 24.

Similar disks 31 mounted to turn on the respective journal hubs of the drier are each provided with a series of cam slots 32 each of which extends in opposite directions from its cam or inclined portion in arcs concentric with and at different distances from the axis of the journals. A shaft 33 journalcd between the end supporting frames parallel with the face of the drier is provided with arms 34 which are connected wit h disks 3] by means of connecting rods 35. A dctont lever 36 secured to said shaft serves to simultaneously adjust the disks in a rotativc direction on the j ournals. The radial bars 38 are each provided with an anti-friction roller 37 whereby it is movably engaged with a correspond'ing cam slot in oneof the disks. The s ots may be circumferentially arranged in the disks for moving all the radial arms and housings with the pressure rolls either in an outward or an inward direction si|'.1ult-a neously or they may be so arranged. circumferentially in their relation to the radial bars as to move them successively or in pairs or in any desired order.

As shown in Fig. 2 the circuml'crcntial position of the slots in relation to the position of the respective radial bars is such that in the upward movement of the detcnt lever the slots will move and maintain the radial bars, together with the pressure rollers 8, 9, 10, and 11, in an outward direction successively and thereafter the front and back ressure rollers 6 and 7 simultaneously and y the downward movement of the detent lever said rolls will be moved toward the face of the drier in an inverse order.

In operation, it is desirable to subject some goods to morepressurethan others in their passage between the a ron and the drier.

By means of the detent ever one or more ofv the pressure r'olls may be instantly moved out of action or returned as the necessity of the goods may require for the most eflicient result. When not in use the lever serves torelieve the apron from the pressure of all the rolls to prevent it from being injured by contact under pressure with the drier.

' Q the drier by'thecontact ofjthe bottom of slots 22 with the bearings therein. The inward movement of the housings carries the pressure rolls in a direction toward the face ofthe drier and the. bottom of the slots 22 beyond the bearings, whereby the exertion of springs 24. on the bearings serves to maintain the pressure rolls with the a ron against the face of the drier under a yie ding pressure.

'Havin fully described my improvement,

,what I c aim as my invention and desire to secure by Letters Patent of the United States is 1 1. Ina mangle, the combination'of a disk rovided with a circumferential cam. slot,

, avingits'end portions extended'in opposite directions concentric with and at different distances from the center of the disk, a bar movably engaging with the slot, and means for rotatively adjusting'the disk for moving and maintaining the "bar in diflerent radia positions of adjustment; r

2, The combination of a cylindrical drler,

aseries of preSsurerolls, anapron partially encircling the drier thereunder, a series ,of housings, bearing boxes slidably mounted therein for said rolls, springs arranged in said housings for The outward-movement of the housings lifts the pressure rolls in a direction from the face of ieldingly maintaining said. boxes in a pre etermmedposition, and cam -mechan1sm for consecutlvely movlng' and similar disks mounted atop osite ends of and concentric with the axis 0 the drier, said disks being each provided with a series of circumferential cam slots, anti-friction rollers secured on the bars and movably engaging with the slots, and hand actuatedmechanism for rotatively ad'usting the disks, whereby the bars and rolls may be moved in predetermined non-simultaneous order and ment. r

5. In a mangle, a rotatively adjustable disk provided with a series of cam slots which are extended at their respective ends in arcs concentric with and at different dismaintained in diiferent positions of adjustv tances from the axis of the disk, radially,

movable bars engaging with the slots and means for rotatively adjusting the disk, whereby the bars may be moved in predetermined order and maintained in predetermined positions in relation to the axis of the disk. I I
