Title: Improvements in or relating to coupling means
IPC: B66B21/12
Filed: 1963-11-29
Abstract: 1,034,968. Rail vehicle couplings. P. ZIPPIGER. Nov. 29, 1963 [Nov. 29, 1962], No. 47193/63. Heading B7T. Two railway vehicles having frame members 32, 35, Fig. 6, mounted thereon may be coupled together successively and progressively in line and side-by-side as in Fig. 4, by sliders 30, 31 engaging slideways 33 or 34. In Fig. 4 a circuitous track (not shown) first engages the slider 31 with the slideway 34, and then as the track curves the vehicles move laterally one with respect to another until 31 and 34 are disengaged. Further movement of the vehicles then engages 30 and 33 so that the vehicles are coupled side-by-side but still orientated in the same direction. A projection 36 assists in the change-over of the coupling position, and the slides and slideways permit limited hinging about horizontal axes. In another embodiment, Fig. 1 (not shown), the sliders are rectangular bars engaging in T-slotted slideways and the projections are in the form of rectangular posts. In Fig. 5 the slideways 26, 27 may be joined one to another in continuation by a member 20 pivotable about a pin 22 on the frame 21 so that a slideway in the member 20 may be aligned with 26, 27. A slider 28 fixed to the frame 29 is contained within the pivoting member 20 as long as the slideway in the member remains out of alignment with 26, 27 and as long as the track continues to prevent the member pivoting into alignment. On alignment, however, the slider 28 may move into either 26 or 27 so that the frames may move laterally with respect to one another. When the slideway in the member 20 is aligned with the slideways 26, 27, or when the member 28 is not coupled up to the member 20, then the member ;is automatically locked by spring- pressed bolts 23, 24 into a slideway aligned position. To facilitate coupling up, the frames may be provided with rollers at each comer, Fig. 7 (not shown).

Title: Sealant-sealed fluid valve
IPC: F16K3/36
Filed: 1965-11-10
Abstract: 1,109,899. Valves. A. S. VOLPIN. 10 Nov., 1965 [4 Jan., 1965], No. 47789/65. Heading F2V. Sealant is automatically supplied particularly to the downstream working faces of the valve gate 30 in response to changes in fluid pressure in the flow passages 12 between open and closed positions. The sealant is introduced initially into a receptacle 70 through an external connection (73), Fig. 6 (not shown), connected to an opening 71. For purposes of symmetry there are receptacles 70 on both sides, that on the chosen upstream side remains relatively inactive. The receptacle is subject to pressure in the valve chamber through pistons as shown; it communicates through a check valve 76 with a reservoir 62 which has a movable wall formed by a seat member 26 slidably mounted in the valve body. This reservoir communicates through a second check valve 79 with a passage 78 so placed that in closed position a sealant retaining groove 77 in the seat connects with the passage through a recess 80 in the gate. In operation, the downstream seat, in closed position, is forced by the line pressure in a direction to contract the reservoir so that sealant is ejected into the groove, In open position the seats and gate re-assume a central position by reason of springs 81,.83 and the reservoir expands to draw in sealant from the receptacle 70. The receptacle is integral with the seat. The gate is in two parts spring-urged apart, the closing together of the parts being limited by fixed stop pins (42), Fig. 4 (not shown) which act as guides for the gate. Lateral movement is permitted by a T-slot connection 38 with the stem 35 which is guided by arms 40 sliding in the body. In open position the stem head 37 makes a metal-to-metal seal with the bonnet 14 at 18 so that a gland 49, 50 can be re-packed. Similarly in closed position by slackening a cap 21 and unscrewing the actuator 46, this actuator makes a metal-to-metal seal with the bonnet at 19, 47 to seal off the gland for re-packing. In another embodiment, Figs. II to 14 (not shown), the receptacle is formed in the housing and the seat is biased by a single spring concentric with the flow passage.
