Abstract: 642,826. Toy car lifts. CRESCENT TOY CO., Ltd., and SCHNEIDER, A. A. Feb. 20, 1947, No. 5019. [Class 78 (iii)] [Also in Group XV] A toy motor car lift comprises a base in which a lifting platform is mounted on pivotal supports, an operating lever, wheel or similar control connected with the pivotal supports so that the lifting platform can be readily lifted to its raised position and lowered relatively to the base, the platform having a pair of lateral members simulating the wheel-tracks of a car lift, a transverse member at either end of the base having an upper ramp surface, and a transverse member at either end of the platform connected to both the lateral members and also having an upper ramp surface, the base and platform members being arranged so that, when the platform is lowered, the platform ramp surfaces lie flush with those of the base transverse members and form therewith inclined runways disposed one at each side of the lowered lift. As shown (Fig. 4-an underside plan view), the base A comprises two longitudinal members 1, 2 of channel-section with closed ends, connected together by transverse members 3, 4 formed with flat under-surfaces 3a, Fig. 2, and inclined upper surfaces 3b shallower than the base frame members 1, 2. The tranverse members also comprise a vertical rear face 3c and a horizontal ledge upon which the platform rests in its'lowered position. The lifting platform B is dimensioned so as to fit within the base frame A and comprises two longitudinal members 5, 6 of angular crosssection arranged with the downward flanges 5a, 6a on the outer edges and with the upper surface furnished with shallow vertical ribs on each longitudinal edge to form wheel guides. The longitudinal platform members are connected together at each end by inclined transverse members 7, 8 which project above the upper surface of the longitudinal members to form stops and which are formed with vertical faces 7b. These faces abut the rear faces 3c of the transverse members on the base frame so that the inclined surfaces form a continuous inclined runway at each end of the lift. The platform is pivoted to the base by supporting links 9, 10 which are in the form of panels formed with top and bottom cross-bars 11, 12 terminating in journals 11a, 12a which engage in journal bearings formed in blocks 1a<1>, 1b on the underside of the longitudinal base members, and in similar bearings on the flanges 5a, 6a of the longitudinal platform members. An 'extension 1b<2> is formed on one of the journals of the lower cross-bar on support 10 and this bears a cranked lever 13 for operating the lift. Recesses 5d, 6d are formed in the downward flanges 5a, 6a of the longitudinal platform members which recesses fit over the bottom cross-bars 12 on the pivotal supports 9, 10 when the platform is lowered. The lever 13 is moved from position X, Fig. 2, to Y to raise the platform. The toy may be formed in cast or pressed sheet metal or in other materials and may be made in various sizes appropriate to toy cars and be ornamented as desired. The control lever may be provided with means, such as a ratchet guide and detent to enable the platform to be more or less raised.
