The shaft 14 :is drivenby a motor` 16 through the `medium of a worm 18and worm gear 20. The shaft 14 it will'ioenoted is vertically mount# ed and has thereon a hat block chuck A. The chuck A comprises a base member 22 secured to' theshaft l4and lhaving pivoted at 24 thereon, hat block engaging members 26. The members 26 are' provided with cam surfaces 28 and with hat block engaging'surfaces` 30. i l

This causes the engaging Figure 4 and dueto the circumferential inclineV ofthecam surfaces28, the surfaces may be as tightlyengaged with the bore 42 as desired.

disk 32 having pins 34 for engagement with the' For positively retaining the engaging members 26 in engaged position with the bore of the hat block, I provide a ratchet wheel 33 secured to the shaft 14 and a spring pressed pawl 35 pivoted to the disk 32. The ratchet and pawl, of course, are of the one-way type so thatthey automatically engage to prevent reverse rotation of `thedisk 32 relative to the shaft 14, but'reverse rotation is permitted whenever the pawl is manually released from the ratchet.

When it is desired to unchuck the hat, the pawl 35 is released from the ratchet wheel 38 and the control member 32 may thenbe `rotated in the same direction that thel shaft 14 rotates for moving the pins 34 in directions opposite the ar rows b for releasing the engagingmembers 26 to the position shown in Figure 3. Y

Spaced from the housing 12 is an upright frame 46. The frame 46 has a horizontal hub 48 in which a tubular shaft 50 is oscillatably mounted. The tubular shaft 50 has a pinion 52 secured thereto. l

slidably mounted in guides 54 is a rack 56. The rack 56 meshes with the'p'inion 52 for impart-v ing oscillation thereto upon reciprocation being imparted to the rack 56.

For imparting reciprocation to the rack'56,f I provide a link 58, a bell crank 60, a pitman 62 and a crank disk 64 having an adjustable' crank pin 66. The crank disk 64 is mounted in afhousingv 67 and has a worm gear 68 meshing with a worm 70 on the vertical shaft 14. The-bellzcr'ank is pivoted at 74 to aconnectr arm 76 connected with the upright frame 46 and. the crank disk housing 67. The crank pin 66, as best shown in Figure. 8,'has a control .knob 66a and is tubular in form. It is interiorly. screw-threaded to coact with a threaded stud 78 which has a head 80 slid-y able in radial guides. 82 formed on the crank disk 64. Thus the throw of be regulated.

A bracket or .mounting 84 is secured to the tubular shaft 50A and has pivoted thereto at 86, an`

ironing arm 88. The ironing arm 88 is provided with brackets 90 to which' a rectangular frame 92` is pivoted on pins 94. An iron 96 is pivoted ony pins 98 which are supported by the frame 92. The pins 94 and 98 are at right angles to each other, thereby the iron 96. s l

The iron 96 vmay be of the ordinaryelectric hat iron type supplied with current from a cable or the like 100 which may be controlled by a switch and a rheostat with-a pilot light for inidica'tingwhether theiron is on in the ordinary manner. 1 f f As shownin Figure 1, the iron is in contact with the top of a hat B. It is retained in such contact by al cable 102v secured at 104 to the arm 88 and having a weight k106 connected thereto.

"I'he cable 102 extends underr a pulley v108 through the tubular shaft 5.0 and over a pulley 110. contact with thehat is especially necessary when the iron is in contact with the. as will hereinafter be described.`

has a bore 63a, while the part 62b has a rod 63 slidable in the bore 63a. otherwise secured to the part 62h.

The rod 63 is pinned or The part 62a has a hub 65 in which is slidably mounted a pin 67. 'I'he pin 67 has a lug 69 adapted to engage a notch 71 of the rod 63. A

y spring 73 normally tends to cause such engagement.

A pin 77 extends transversely through the pin 67 and is adapted to coact with opposite notches .79 of the hub 65. This construction forms a clutch, the purpose and operation of which will hereinafter be fully described. Its relation to the rest of themachine is'shown diagrammatically in Figure 1c.

Practical operation I In the operation of my device, the motor 16 may be Aenergized for operating the machine and with the arm 88 in inoperative position, a hat block with a hat therein may be chucked for ironing the hat' (see Figure 9). In this figure,- a band-B is shown on the hat. With the guides 82 in alignment with the pitman 62, as in Figure 7, the knob 66a may be loosened and the handle 88a of the arm 88 grasped by the operator and swung yto position with thev iron 96 contact with the hat. Theiron is adjusted to' a position adjacent the band B', as shown at the left of Figure 9, this'being possible while the machine is in motion because the crank disk 64 rotates very slowly.

The knob 66a may then be tightened, whereupon the bracket 84'will automatically oscillate so that the iron 96 willtravel from the left'to the right side as shown in Figure 9 and back again, this cycle being repeated as long as the machine is left in'operation. Where the band is removed from the hat, the stroke of the pitman 62 can be increased so that theiron will travel as shown at the lower left and lower right of Figure 10, or where only the topfof the hat is to be ironed, the stroke can be shortened as illustrated at the top of Figure 10.

lSometimes it is desired to rotate the hat block chuck A but not oscillate the iron 96. This operation, for instance, facilitates certain cleaning operations on the hat when it is desired to have therhatirotate and hold a cleaner sponge against it for instance.

It is also desirable to have the hat rotate while holding a damp sponge against it just prior to ironing the hat. The clutch I have shown in Figures 1a and 1b serves to disconnect the hat iron 88 from the crank disk 64 as will now be described.

The head 75 of the pin 67 maybe pulled outwardly against the action of the spring 73 for disengaging the lug 69 from the notch 71. 'Ihe pin 67 may then be given a half turn so that the pin 77 is out of the notches 79 and on the end of the hub 65. Thereafter the link portion 62a may reciprocate without imparting reciprocation to the rack 56, which then will not impart oscillation to the arm 88. As a matter of fact, the arm 88 will have a tendency to either lower or raise the rack 56, depending on which side of the machine the arm happens to be.

Automatic oscillation of the iron arm` 88- willthen commence. 1:Hat' 'ironing machines have heretofore been used, but most of them lack thefconvenienoe and precision embodied in my invention.`

Particularly with reference to the vertical mounting of the hat chuck, the details of the hat chuck itself and the universal mounting of the iron, I have provided a very efficient machine. By arranging the shaft 14 vertically,` the hat block can be chucked in a vertical position, which is the most natural position for the operator.

The hat block chuck is arranged so that it can be readily manipulated for either chucking or unchucking the hat block. With a minimum number of parts for mounting the iron 96 (a single pivoted arm 88 being provided) I am able to provide accurate tangent relation of the iron 96 to any point of the hat B by the universal mounting provided by the pivots '94 and 98. Also the same weight which maintains the iron in contact with the hat serves effectively to retain the arm 88 in inoperative position while one hat is being unchucked and another is being chucked. c

Some changes may be made in the construction and arrangement of the parts Aof my device without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents, `which may be reasonably included within their scope.
