Abstract: 13,008. Blogg, S., and Blogg, M. June 4. Seat-guards, door-action. The web of seatguards on the roller a, Fig. 1, is led over a roller c between the hinged side-cover d and the seat, across the seat e, between the seat and the other side-cover, round a roller f on a shaft p, and between this roller and a spring-pressed roller g into a receptacle below. Connected with the closet door is one end of a rope h, to the other end of which is secured a block i sliding on a rod k and which is engaged by a catch l mounted on the rod k. A rope n secured to the catch l and wound round the pulley n is secured thereto at o. A ratchetwheel q provided with eight teeth is keyed on the shaft p, and loosely mounted on its hub is a ratchet-wheel r which has a maximum diameter greater by the depth of a tooth than that of the wheel q and which is provided with eight teeth, four of the same depth as the wheel q and four twice that depth. A pawl s pivoted to the pulley n is wide enough to engage both ratchet-wheels simultaneously. In the normal position, the pawl s engages a deep tooth of the wheel r and a tooth of the wheel q. When the pulley n has been rotated through 315 degrees, to bring a fresh guard into position, a trip u releases the catch l, which is returned to the normal position by a spring w, causing the pulley n to return to its ordinary position, the pawl s being then clear of the wheel q and only engaging a shallow tooth of the wheel r. When the door is again opened to vacate the closet, the wheel r is rotated, the wheel q, and thus the shaft p and roller f, remaining at rest. The wheel r is maintained stationary on the return of the pulley n by a blade spring x secured at one end to the wheel q, the other end being provided with a pin which projects through an opening in the wheel q and engages one of eight recesses y in the wheel r. In a modification, Fig. 3, the closet door 1 is provided with a forkshaped block 2 to which is pivoted a tube 4 provided with a collar 6. A rod 5 which slides in this tube has a vertical slot in which is resiliently mounted a pivoted catch 7, Fig. 5, provided with a hooked end which normally engages the edge of a slot in the tube 4. The rod 5 is connected by a bell-crank lever 8 to a two-part rack 9 operating a pinion 11 secured to a disk n<1> which co-operates with ratchet-wheels q, r as before. The trip 12 operates the catch 7 when the disk n' has turned through 315 degrees and disconnects the rod 5 and tube 4, the tube continuing its movement alone. In a third modification, Fig. 6, the rod 1 operated by the opening of the closet door or the movement of a hand-lever moves by a bell-crank lever 2 a lever 3 to which is connected, by a lever 8 engaging a pin 30 thereon, a lever 4 connected by a universal joint 10 to a lever 13 which operates a toothed sector 25 engaging a pinion 19 on a shaft 18, Fig. 8, carrying the web roller 17 and fixed to a disk 20. Fixed on this shaft are disks 21, 22, the disk 21 actuating the roller 17 and the disk 22 co-operating with a detent 23 to limit the rotation of the roller. When the rod 4 is moved, a lever 28 withdraws the detent 23, the sector 25 operates the pinion 19, and a detent 24 on the disk 20 engages a tooth 29 on the disk 21 to operate it. When the roller has turned through 315 degrees, a pin disengages the pin 30 from the lever 8 and disconnects the rods 3, 4. The casing 12 is mounted on the arm 26 of a pivot 27 allowing it to be raised with the seat.
