Loose clutch member structions and combinations andy arrange-V 34 is hollovv and at its upper portion there is'v ments of parts, clearly described in the folattached thereto an eccentric 36. .y i f 100 At the upper end of shaft there is provided a double universal joint 37 capable olf a rotary and reciprocating motion. The upper portion 38 ot the joint is guided in a slot 39 and comprises a slide 40, guided in a frame 41.

Slot 39 is provided within the work-table and also accommodates beside the joint end 38 an eccentric engaging member 42 depending downwards from slide 40, and provided with a friction reducing arrangement indicated at 43 and comprising a roller vertically mounted with engaging member 42. Through slot 39 also extends a bracket 44, the lower end of which is engaged by a coil spring 45 attached at 46 to bearing support 47.

Spring 45 is adapted to exert constantly a pull upon bracket 44, thereby causing slide 40 to bear in lett hand direction, as shown in Fig. 1.

Extending from guide 49 above joint end 38 there will be seen mounted a vertical shaft 48, to which is keyed the hollow extension 49 of block support 50, adapted to receive an exchangeable hat block 51. Hollow block support extension 49 is preferably adjustable relative to shaft 48 by means ot wing screws 52.

Attached to block support extension 49 there will be seen a tray 53 adapted to extend beyond block support so as to prevent any refuse, dust, etc. from entering the mechanism operating the block support.

In the rear of the blocl support there will be seen a standard 54 extending from worlrtable 11 upwards and forming a support for a hat drying mechanism, which consists of a bracket 55 provided with a pivot 56, at which is fulcrummed a lever 57 normally held in upward position by means of a spring 58 engaging end 59 of lever 57 and attached at 60 to table :trame 10.

Lever 57 is provided with a substantially f vertical hinge connection 61 at which is attached hand lever 62, adapted to be pulled downwards manually by means of handle 63. At the first bend of leverextension 62 there will beseen provided a hinge connection 64, from which depends a suspending arm 65, connectedk with a hat drying die 66. lhe latter consists of a hollow body adapted to receive the hat mounted on block 51 and is provided with handles 67 and a gas heater connection 68.

Upright shaft 48 of the hat block support is preferably hollow and extends into the hat block support portion 50, which is also pret'- erably hollow as is the hat bloc-lz itself. The latter, while not so shown, is preferably provided with a plurality of minute periorations so as to permit steam entering shaft 48 to penetrate through the pertorations into the hat material when so desired. The steam connections are not shown. However, at the lett Leases@ side on the work-table, as seen in Fig. 1, there is illustrated a steam control valve 69, which is operated by means or" a valve handle 7 (l, shown in Figs. 6 and 7 in det-ail, by means of lever 71 forming part of the control mechanism of my machine.

Referring to the right hand portion or Figs. 1 and 2, it will be observed that horizontal gear 27 of the drive mechanism ot my device engages a similar horizontal gear 72, which is keyed to shaft 73 journaled in vertical bearing 74. Shaft 73, extending upward at 75, is provided with a long key 76, adapted to engage an outwardly threaded hollow spindle 77.

A portion et the work-table 11 is provided with an enlargement in the form of a casing 7 8, which is provided with an internally threaded aperture 79, adapted to be engaged by spindle 77. At both sides of the spindle engaging portion of casing 7 8 there will be seen vertical side guides 80, in which slide guide bars 8l depending from tool support trame 82. The latter is provided with a central aperture 83, through which passes the upper extension 84 of sleeve spindle 77. rlhis extension 84 is rotatably mounted in aperture 83 so as to permit a free movement ot' spindle 77.

Right below the center portion of tool support 82 and attached to spindle extension 84, there will be seen a collar 85 permanently secured and provided with a pawl 86. A similar collar 87 will be seen attached to spindle 77 and equipped with a similar pawl 88.

l-lingedly associated with tool support 82 at 89 there will be seen two parallel bars 90 extending upwards and provided with hinge connections 91 at their upper ends. With these connections there are associated depending lugs 92 of tool rest 93.

As will be readily seen from Fig. 1, parallel bars being hinged at both ends, are capable of a. swinging motion, and in order to assure these bars to assume normally a vertical position, as shown in Fig. 1, lcoil springs 94 are provided at each hinge connection ot the bars.

At the right hand end of tool rest 93 there will be seen provided adjustably mounted extension 95 equipped with an anti-friction roller 96, which latter is in engagement with a pattern 97, adjustably mounted in standard 98 extending from the right hand elge ot work-table 11.

attern 97 is exchangeable and is provided with a profile edge 99, which is engaged by roller 96.

At the right hand end of tool rest 93 there will be seen a hinged bracket 100, to which is attached a multiple finishing tool 101'at 102, and which latter comprises a number of individual hat i'inishing tools, as will be explained presently. rlhe center portion of the to swing in left hand directiomdue to the fact'that it is pushed yin, that' direction by extension 95engaging profile 99 ot' pattern 97.v AIn that manner. the individuali tool, adapted to engage the hat on block 51, moves thereagainst while the latter rotates. AThe upward lmovement continues until roller 96v reaches its uppermost position, shown in broken lines in Fig. 1, and then spindle 77V is caused to revolve in the opposite direction, whereby the tool support 82is caused to descend and tool rest 93 swings back in right hand directio-n to its normal position when it reaches its lowermost stand.

The upward and downward movement of spindle 77 is controlled bya lever arrangement best seen in Figs. 2 and 3. t the front edge olf table frame 10 there will be seen a guide bracket 104, in which oscillates a lever 105 provided witha handle 106. Lever 105 is pivoted at 107 and isprovided withl an eX- tension 108 terminating in a hinge connection 109, in which is mounted a bracket L110 engaging an operating rod 111.

Operating rod 111 is shown in cross-section in Fig. 1 and is held in place by means of set collars 112, attached to sliding rod 113, guided l at its ends as shown at 114. Rod' 113 is capable of reciprocation caused by lever 105.

Attached to rod 113 there will be seen bifurcated members 115 engaging loose coupling members 18, keyed to shaft 14.

At the upper end ot bar 105 there will be seen attached at 116 connecting levers 117 and 118, clearly seen in Fig. 2. These levers engage at their free ends actuating levers 119 and 120 respectively, which are pivoted at 121 as clearly seen in Fig. 2. These actuating levers are adapted to be engaged by pawls 88 and 86, respectively, while threaded spindle 7 7 travels in downward or upward directions.

To start the machine handle 106 is swung to the right. By so doing actuating lever l120 is caused to swing'with its outer end in right hand direction and with its spindle pawl-engaging end in left hand direction. Lever 119 however is moved with its inner pawlengagin g end against the spindle.k

By loperating handle 106 in right hand direction the right hand yoke 115 causes -coupling member 17 to engage coupling member 19, thereby causing the operating mechanism of the spindle to revolve in anti-clockwise direction. it the same time spindle 30, controlling the operation of block` support 50, is

alsov caused to rotate in anti-clockwise direcit pushes the Vlatter in left hand direction' tion. When the spindle 77 reaches a point where collar ,87 arrives at the plane otlever 119, pawl 88 engages that leverand causes o I the same to move in righthand'direction, thereby imparting a lefthand' movement to bar 105. This movement of the bar causes.'

the disenofa ement of cou lin member 117 from' coupling member 1,9 and the-engagement of friction member 18 Vwith friction member 20. This change reverses the operation of spindle 77 andalso ot's'pindle 30`of the,

mechanism.

vThrough the movement of lever 1.05 Y

ating lever 120 is also caused toengage with its operatinoN end spindle 77. Vhen' the reversal of movement of spindle 77 has taken place, 'the latter descends untilc'ollar 85 with its pin or pawl 86 reaches the planeyof lever The mom-ent pawl 86 engages lever 120 thereby causing bar 105 to assume its normal central position shown in Fig. 2,which causes disengagement, of clutch member 18 from clutch member20. At this moment all opera-r tions above the tablestop and in order to bring the machine into operation again it is required that handle 106 is thrown in right hand direction. l

It will be observed that pin 88 is considerably ylonger than pin 86.V rlhe difference in length othese pinscauses a difference in operation, thus pin 88being longer throws lever or bar 105 a 'ull strolre to its eXtreme left hand position, while the operation of pawlj86 causes bar 105 to move only half Away into its normal middle position explained above.

Referring tooFig-s. 8 and 9, the construction.

of my multiple toolconsistsof a center arbor 122, controlled by `a clamping handle 123 by means ot which the position of the individual tools attached to vbody 124 of the multiple tool may be adjusted in desired relation to hat-block 51.

In each corner ot body 124 ltherewill Vbe seen individual tool rests 125, 126,127 and 128.r Each one of these tool rests consists of a socket 12,9, in which is lodged a spring 130 bearing against the end tace of tool pin 131, l

ly mounted bynieans ot screws 141 in tool y heads 137. v f V The lett hand toolv shown in Figs. 8 and 9 comprises what is known as an', ironing tool,

whichr is electrically'h'eated and which is preferably equipped with a handle bar-14.2. The

ironing tool consists of heated block 143, which is preferably held under tension by means of spring 144. The tool indica-ted at the upper end of Fig. 8 and extending from socketl27 is what is known as a sand-bufling tool and consists of a sand paper block adapted to roughen the surface of the hat. Y The right hand tool shown in Fig. 8 is what is known as a hiring tool and consists of a soft felt' padprovided with press cloths on top. A similar tool is shown on the lower end of Fig. 8 extending from socket 125, which is similarly built as that shown on the right hand side, but may be provided with either l a rougher or smoother` cloth surface than the formerly mentioned luring tool. YThe hiring tools are vall heated.

Operation- The dierent movements of my machine having been explained in connectio-nwith the description of the drawings,

the function of my device is as follows: A proper hat block 51 is secured to block support 50 and a hat is mounted on hat block 51. A pattern with a proper profile is attached'and adjusted in standard 98 and the required individual tools are mounted in the multiple tool head 101. It is usual that rst th-e buh'ing tool is employed in order to roughen up the surface of the felt of the hat form and the hat block is rotated first in one and then in the opposite direction while subj ected to the buffing operation. Then the tool head is turned ninety degrees and either one of the hiring tools comes into action and the operation of the machine is repeated. The first hiring operation may be then followed by another hiring operation, and after the hat form is considered to be otherwise finished the ironing tool is applied.

The various applications of the individual tools is more or less left to the choice of the operator as it depends entirely upon the material of the hat form which one of the operations is to be employed first, repeated, or ventirely left out. V

In some cases the hat form has to be cleaned and may be subjected to a wet cleaning process, which requires drying or partially drying of the hat form on theblock, in which case the application of drying mechanism 66, shown in Figs. 1 and 3, is employed.

The reciprocating movement Vof block support 50, while rotating in either clockwise or anti-clockwise directions, is accomplished by the co-operation of eccentric 36 with eccentric engagingmember 42 and spring 45. The latter tends to pull :slide 40, in which is revolvingly lodged shaft 48, in a left hand direction, while eccentric 36, when in the position shown in Fig. 4, presses against member 42, thereby forcing slide 40 in a right hand direction.

This reciprocating movement of slide 42 mav be terminated bysliding clutch member 34 out ofxengagement with clutch member 33, through an upward pull of lever 35.
