Filed: 1928-05-22
Abstract: 321,962. Mechanical & General Inventions Co., Ltd., Lehwess, E. E., and Smith, H. May 22, 1928. Hoods.-In vehicles of the kind in which a roof opening is adapted to be closed by a movable covering one or more pairs of pivotally interconnected non - extensible members are connected to the hood and means are provided for operating said members to move the hood whilst means serve to restrain said members so as to convert them into rigid members in order to enable them to sustain a push to effect movement of the hood. As shown in Figs. 1 and 7 an endless chain 4 runs in channels 3 in the cantrail 1 and passes over sprockets at the front and rear ends of the roof. The chain is operated from a shaft by means of a crank 10 or by power or other means. The cover 22 is supported by hoop-sticks 12 which are interconnected by links 13 which are connected together at their adjacent ends by a roller chain link 20 which runs in a channel 21. The sticks are provided with rollers 17 running in channels 18 provided with a restraining strip 19 which extends along the horizontal part only of the roof. The front link 13 is connected to the chain 4 by a bracket 26. When the roof is being opened or retracted the rollers 17 leave the channel 18 at the ends of the strip 19 and the links 13 fold up to fold the hoop-sticks 12 at the rear of the vehicle as shown in Fig. 2, abutments 12a being provided on the links tc prevent the cover being nipped between the hoopsticks. The rear hoop-stick 14 may be in the form of a cage into which the cover may be folded. The front hoop-stick 12 is adapted to be locked against a fixed bar 27 by a locking device which is adapted to prevent the chains 4 from being operated until the device is unlocked. The rear portion of the roof may be hinged, and when lowered serve as a rest for the collapsed hood.

IPC: D03D37/00
Filed: 1919-06-02
Abstract: 144,297. Crespi, S. B. Sept. 21, 1918, [Convention date]. Circular looms.-In a circular loom with electromagnetically-operated shuttles, as described in Specification 133,020, a soft iron ring 10, Fig. 2, is arranged on the outside of the shuttle rack to reduce the centripetal radial attraction on the shuttle, which is provided with iron blocks 1 connected by non-magnetic plates 3, Fig. 3. The ring closes the magnetic circuit from the poles of the travelling magnet, but to reduce somewhat the attraction of this ring, a shunt circuit is provided to take a portion of the magnetic flux by a connecting-rib 4, which is situated between the blocks 1, but is of less cross-section than the ring 10. Better balancing of the shuttle is effected and its displacement is prevented by forming the adjacent faces of the blocks 1 and the ring 10 to present obtuse angles towards one another as shown. The newly-laid weft pick is beaten up by a wheel 8 before a projection 7 lays down the succeeding pick. The shuttle turns on rollers 5, 6 and wires 9 keep the warp threads apart.
