Abstract: 954,393. Selective retrieval storage systems; garage lifts. R. BAJULAZ. Oct. 25, 1961 [Nov. 4, 1960; Sept. 6, 1961], No. 38270/61. Headings B8E, B8H and B8L. A storage system consists of a plurality of carriers 6 which are movable along a horizontal track 1 and a lift 2 operating in a vertical shaft which intersects the track, the carriers 6 and the lift platforms being such that a load on the platform is automatically transferred to one of the carriers, or vice versa, on movement of the lift platform through the plane of the track. The multi-storey garage in Fig. 5 comprises such a track on each of its five underground storeys, each track being circular and of a length equal to an integral number of carriers but a one-carrier space 7a, Fig. 1, being left permanently vacant. In use a vehicle is driven into the lift at ground level, the space 7a on four of the storeys is located in the lift shaft and an unloaded carrier 6 in the other storey presents the only obstruction in the shaft. The lift platform 40 and the carriers 6 have complementary tines 42 and 12, respectively (see Fig. 2) so that the platform can pass the plane of the carrier and deposit the vehicle thereon. To allow the platform to pass through the trades 1 the latter leave gaps aligned with the platform supports 44. Control of the lift and of the carriers in the above operation may be by means of an electric switching system, Fig. 14 (not shown), which ensures that only a selected one of the system's carriers is brought into the lift shaft. Such carrier may be locked in position by a pneumatically powered electrically operated catch 72, Fig. 2, which engages a wheel of the carrier. As each carrier passes the lift shaft it operates a counter which signals to the control gear which platform is present and the control gear has memory devices, responsive to upward or downward movement of the lift platform, which record whether or not each carrier is loaded. Lift construction, Fig. 4.-The lift platform 40 is in two halves, each carried by its own motordriven endless chain 45. There are preferably two such platforms, the two halves (not shown) of the second platform being guided to pivot into a position parallel with the respective chain on its outer run and coming into load-supporting position at the top of the chain's inner run just as the other platform leaves the bottom thereof. Access to the lift is by way of an entry normally closed by " up-and-over " doors 51, Fig. 9 (not shown), which operates in conjunction with a horizontal slide 52, Fig. 5. Construction of carriers.-The carriers of Fig. 2 each comprise a spine 9, tines 12 and a single axle 8 at one end for one pair of running wheels, the other end of the carrier being permanently pivotally coupled to the axle of the adjacent carrier. Drive is by a motor coupled to the axle of one of the carriers. In Fig. 15, the tines 12 are tapered, to obviate the need for precise alignment with the lift platform tines and to dispense with the carrier locking means. In this form the track is an L-shaped monorail 100 on which run bogies 106 comprising wheels 110, 112 for engaging the track and a frame work which bridges a supplementary track comprising rollerways 103 which are provided at least where the monorail is broken to accommodate the lift. The carriers' spines 9 are each pivoted to one of these bogies at each end. Drive of this embodiment of carrier is by a taut endless cable 119, Fig. 18, which engages pulleys 112 on the carriers but which is routed outside the lift shaft by deflecting pulleys 118. A lift and carriers as above may be used in a system comprising concentric tracks on a single storey or on each storey of a multi-storey system. The system may also be adapted for non- garage applications, e.g. bank strong-rooms or automatic self-service restaurants.
