CLAMIING CLIP IOR NECKBAND EXPANDERS.

Application fired February 1, 1922. seri-.11110. 533,349.

This invention relates to improvements in neckband expanders used in connection with `the ironing of shirts and more particularly rthe type used to expand the neckbands of shirts having collars attached.

' The objects of this invention are to provide a neckband expander with an improved clamping clip together with means for lock-Y ing the Clip in clamping position; and more specifically to4 provide a `locking means nwhich has pivotal and sliding movement for releasably locking the clip in clamped posi- 'l tion.

y Other yobjects of the invention lwill Vbe 4 apparent from the following, description and claims 4,when considered togetherY with the accompanying drawings. i o

Fig. y1 is a vvertical Vlongitudinal section of an ironing board embodying my improved device; Fig. 2 is la transverse section taken on line 2 2, Fig. 1; Figa?) is a sectional lview similar to Fig. 1, showing part of the device with clamping clip in raised X v theslide bracket 17 is the clamping clip 21 which is 4adaptedto ybe lowered for clampposition; 4 is a view similar to' Fig. 3 with the clamping clip in lowered position; Fig. 5 is a plan view of the neckband expander; Fig.v 6 is a horizontal section of the neckband expander taken through the plane of line 6 6, Fig. 2: is a section taken through the planeof line 7 7, Figs, 2 and showingthe lock in ,detailrandFigg 8 is a support 2. .The main `stationary portion oi' section taken through the planeofline 8 8, Figs.` 2 and 5 showing the other side ofthe Vlock in detail.

The guide 1 is suitably mounted upon the V main table or support. 2 .and is provided with the bracket 3 for support of the guide plate 4 for'the neckband former. The ironing table 5 ismounted upon the support 6 v *which has sliding movement upony the main the neckband former is indicated at 7 while "the rear portions 7 are adapted for adjusta-` ble movement according to the shape and size ,of the neckband ofthe shirt. lhe ad'- justable extensionblocks 7.have slidable movement Yin one direction bymeans of their' guidepins8 engaging the main stationary part'V ofthe-'neclrband former and'in the otherdirection along theguide pin 9 which extends Ythrough the top portionl of the yoke gplat-e '10, and is secured thereto by means ot' theset4 screw 11'. The mechanism for oper- :ating the yoke` ironingrv member 10a forms no part of the present invention. The pins 12 extend through theguides 13 and through the `stationary portions 7 of the neckband expander whereby it ispossible for the neckband expander to yield downwardly as mayl be necessary during the ironing operation, the upper rear ,portions of the-ironing table 5 being cut Vdown as indicated at 5f? to perimit such depression of the neckband expander during the Ironing operation.' The springs 12a are providedyfor the pins 12.,v

guide plate 4 and the main part of the neckband expander. The pins 12 extendalso through the brackets 15 secured to the underside of the guide 'plate' 4. Slidably band expander there is provided the bracket 17 which has the ribs 18 engaging in the' `slots 19. The bracket 7a on the mainv Vpart 7.0i the neckband former has a projection surrounded byfspringj17a the other end of which abut-s the bracket 17. ,e Pivotally lmounted at the point20 upon ingengagement with the front lportion of the neekband ot the shirt. The locking -member 22 is provided with a slot.` 23gfor slidable engagement-with they flat `faces ofV to have vthe slot 23 engage the iiat'aces ot the pivoty 20, thereby preventing raising of the clip 21. y

The vguide pin 28, which extends through the expander 7, is connected at lits oneV end 'these springs having `abutment against lthe "mounted-upon the main part of the neoky with the screw 29 secured in the sliding bracket 17 while the other end of the pin 28 extendsthrough the opening 30 in the yoke plate 10. rThe pin 28 extends valso through the depending arm of the guide pin .lockBl which is provided with thebutton `32 for manipulation thereof. The lower end of the lockx31 vengages in the-recess 32` formed in the slide 38 which is mounted in the neckband former. The guide. pin 28 is provided with a shoulder 34 for engagement by the opening in the lock member 31,V that is, upon sliding adjustment of the bracket 17 after the clip 21 has been lowered toengagethe neckband of the shirt. rEhe spring f 35 tends to hold the lock 31 in engagement with the shoulder 34. The stop collar 3G which is mounted in the neckband expander is adapted to be engaged by the stop point of the screw 29 land `also by the. stop screw 37 which is provided upon the slide 33.

The slide 33 is adjusted by means of the bell crank vlever 38, the upper end of which has pivotal connection with the slide 38 at the point 89. Y The pin 40 carried by the bell crank lever 38 engages the vertical grooves 41 formed in the sides of the depending brackets 15, thereby providing` a pivot point for the bell crank lever. The lower end of the lever 38 has pivotal connection at 43 with the shackle 44 carried by one end of the rod 45. The rod 45 carries a swivel block 45 which can be slid thereon against the tension of spring 47 whose other end abuts against the nuts 48 carried by the rod 45. The collar 49 on the rod 45 limits the movement of the swivel block in the other direction. The arm 50 of the bell crank lever 51 has pivotal connection with the swivel block 46 and is provided with the rollers 52 which are adapted for engagement by the cam 53 which is mounted upon the shaft 54-and can be operated by the lever arm 55. The segmental gear 55 which is also mounted upon the shaft 54has meshing engagement with the companion segmental gear 57 mounted upon the shaft 58 which carries also the arm 59 with the roller V60 for engagement with the sliding support 6.

After dressing the shirt upon the ironing board, the clip 21 is lowered so as to engage the neckband, the lock 22v having been adjusted to permit pivotal movement of the clip. The locking member 22 is then slid into locking position so as to prevent raising movement of the clip, and the bracket 17 is slidably adjusted against the tension of spring A17a so as to cause the shoulder 84 to be engaged by the edge of the opening through the arm of the locking lever 31, the spring 35 tending to hold the lever 31 in such engagement. This movement of the sliding bracket 17 tends to further clamp the clip 21 in engagement with the fronty portion of the neckband. rlhen upon raising the lever 55, the cam 53 will engage one of the rollers 52 so as to cause rockingl movement of the bell crank lever 51 and movement of the arm 50 to the right as viewed in Fig. 1. The spring 47 isthereby placed under tension and the rod 45 is moved to the right, causing` the slideV 33 to move to the left, as viewed in Fig. 3. By

virtue ofthe engagement of the lever 31 in the notch 32 together with the engagement of the lever 31 with the shoulder 34, the movement of slide 38 causes firm clamping action'of the clip 21. rilhis action takes place prior to the engagement of the roller GO with the sliding support 6. Further operation of lever 55 will, through gears 56 and 57, cause engagement of roller 60 with .support 6 so as toniiove the ironing table and yoke plates to the left as viewed in Figs. 1 and 3. At the saine timethe rear portions of the neckband former are eX- tended according to the sizeV and shape of the neckband which is thereby. placed under tension. The shirt is then in condition for the ironing operation.

Upon completion of the ironing operation7 the lever 55 is lowered so as to cause the roller 60 to engage the web to return the support 6to the position shownin Fig. 1, and to relieve the tension on the neckband of the shirt. Depression of the button '32 will release the engagement between the lever 31 and the shoulder 34, whereupon the spring 17L will force the sliding bracket 17 to the right, as viewed in Fig. 3, thereby relieving the clamping action of the clip 21. rEhen upon sliding adjustment of the locking member 22, so as to bring the end portion` 27 of the slot to surround thepivot pin 20, the clip 21 can be raised so as to altogether release the neckband of the shirt.

Since the ironing` board has an angular pitch, as illustrated in the drawings, it is possible to employ my present invention to iron a shirt having an attached collar as well as the ordinary shirt without the collar; since, upon applying tension to the neckband,` the attached Acollar is caused to lie on the angular surface and will not be damaged by the engagement ofthe ironing chest. rlhe operation is the same in the two position to said support, yielding means opposing inward movement of said support toward the center vof said former, and means arranged to hold the support when moved to its inner position.
