Title: Improvements in or relating to ironing machines
IPC: D06F71/22
Filed: 1930-01-02
Abstract: 339,151. British-American Laundry Machinery Co., Ltd., (American Laundry Machinery Co.). Jan. 2, 1930. Shirt-clamps for ironing-machine.-The substantially semi-circular strap 29 that coacts with the neckband block 4 is secured at its ends to a member 28 freely mounted on an eccentric 23, Fig. 6, on a shaft 24 provided with a crank handle 25, Fig. 4. One end of a pin 32, Fig. 6, projects from the eccentric and travels in a semi-circular slot 31 in the eye at the end of the member 28 of the strap 29. The counterclockwise rotation of the shaft 24 is limited by the engagement of a lug 26, Fig. 4, on the crank handle with a stop 27 and in this position the strap is in the raised position and is counterweighted by the crank handle, the pin 32 engaging the lower end of the slot 31. Clockwise rotation of the crank handle then lowers the strap into a position adjacent the block, the pin still engaging the lower end of the slot until the strap contacts with the bed 3 whereupon the eccentric is rotated within the eye of the end member 28 to draw the strap into clamping engagement with the block, this movement being limited by the engagement of the pin with the upper end 31b of the slot. Reverse movement of the handle first moves the strap out of clamping engagement and then, when the pin 32 reaches the lower end of the slot 31, raises the clamp and counterbalances it.

Title: Improvements relating to protective helmets (headgear)
IPC: A42B3/22
Filed: 1957-01-09
Abstract: 798,923. Safety helmets. MINE SAFETY APPLIANCES CO. Jan. 9, 1957 [Jan. 19, 1956], No. 843/57. Class 63 A protective helmet 1 has an openbottomed pocket formed on its front wall in which there is a vertical slot 9 carrying retaining means that attaches a removable eyeshield 12 and can be slid up and down in the slot 9 to move the eyeshield in and out of the pocket. Extending above and below the ends of the front edge 2 of the helmet are a pair of grooved tracks 4 which are covered by a protective plate 7 secured on to, and extending between them to form the pocket. The eyeshield 12 is transparent and has a central notch 13 in its lower edge to accommodate the nose of the wearer. Its edges slide in the tracks 4. Tabs 28 on locking members 29 normally engage in slits 27, Fig. 3 (not shown), cut near, and parallel to, the lower outer edges in the eyeshield to prevent it from being pulled out of the track grooves by wind blast &c. A retaining member extending through the slot 9 has a shank 15, Fig. 5, at its outer end with a head 16 engaging the inner surface of the eyeshield and a flange 17 between the eyeshield and the plate 7. The shank 15 carries two locking pins 18 which normally engage holes 19 in the underside of binding strips 10 along the edges of the slot 9 to retain the eyeshield in a chosen position. The retaining member has a square stem which extends through a square hole in a knob 21 in front of the plate and is retained there by a button 24 whose screwed stem engages in the shank 15. The button 24 has a square hub 22' which prevents it from rotating in the slot 9 when it is in its normal position. When the button 24 is pushed inwards against a spring 25, the pins 18 are disengaged from the holes 19 so that the eyeshield can be moved. A portion 33 of the retaining member is oblong in cross section where it engages with the eyeshield 12 and the notch into which it engages is keyhole shape, Fig. 7 (not shown). By these means the eyeshield can be detached from the retaining means, if, after disengaging the pins 18, the knob 21 is pulled outwards and is rotated. To remove the disengaged eye shield from the helmet it is necessary to clear the locking members 29 from the ends of the tracks by lossening the screws 30.
