Abstract: 15,630. Alber, J. G., and Benjamin, D. H. June 30. Ironing - machines with pressing action only; boards for; shirt-clamps for.-A machine for ironing shirts comprises a pair of ironing-boards yieldingly mounted on standards, and a double-faced heated ironing - member mounted on a horizontal shaft so that it may be swung by hand about the axis of the shaft to engage with either of the ironing- boards. The machine also comprises a power-driven cam which is moved by belt and worm gearing into engagement with the end of one of a pair of arms on the shaft carrying the ironing-member, so as to give a final ironing pressure, and an extensible neck-band former and a yoke clamp fitted to each ironing-board. The ironing-boards 16 are provided with a longitudinal rib 15, Fig. 6, resting in a groove in a spring - mounted block 13, so that they may be capable of rocking transversely in order to take the pressure evenly. The ironing-member 67, which may be heated by steam, is carried by arms 69 on a shaft 9, and counterbalanced by a weight 73, the shaft 9 being rocked by means of an arm 66, Fig. 5. Arms 70 are provided on the end of the shaft 9 for engagement by the powerdriven cam 74 to effect the final ironing-pressure. The neck-band former, shown in plan in Fig. 11 as extended, comprises a plate 51 secured to the ironing-board, and a portion 55 engaged by pins 19 which pass through slots 53 in the plate 51 and are secured in a boss 18, Fig. 6, in the support 13, the extension movement being obtained from a longitudinal adjustment of the ironing-board 16 on the support 13. Rear parts 58 of the neck-band former are connected by links 65, 60, the latter having slots 61 engaging the shank of a clamping-screw 62. The means for adjusting the ironing-board to effect the extension of the neck-band former comprises an arm 22, Fig. 6, engaging a notch in the rib 15 and carried by a shaft 21 provided with a handle 26 having a screwed brake block 25 adapted to engage the periphery of a sleeve 23, Fig. 5. The rear end of each ironing-board is provided with a pivoted yoke clamp 33 which is put into and out of engagement with the ironing-board by a spring toggle device 36, 37, 41 actuated by a rod 44 connected to a treadle. The transverse rocking movement of the ironing-board is limited by the engagement of hooks 50 on the support 13 with rails 29 carried by the ironing-board. The gearing for operating the cam 74 comprises worm gearing on a shaft 80 driven in the required direction by either of two belts running on idle pulleys 82, 83. The belt forks 91, 94, Fig. 5, are carried on a movable bar 84 connected to a pivoted bar 96 engaged by a curved bar 99. This bar is fitted with a clutch member 101 pressed by a spring into engagement with another clutch member 107 on a shaft 102, and is normally kept in a central position by pins 110 on a member 109 on the cam shaft, so as to prevent the belts from being moved. To rotate the cam into its operative position, the shaft 102 is first moved axially, by a hand-lever 105, so as to move the curved bar 99 clear of the pins 110, and is then rocked so as to shift one of the belts ou to the fast pulley 81. On the release of the handlever, one of the pins 110 strikes the bar 99 and moves the belt back to its idle pulley, but the cam remains in its operative position, from which it is released by moving the other belt on to the fast pulley, this belt being returned automatically by one of the pins 110 as before.
