Title: Windscoops
IPC: B63B19/02
Filed: 1928-06-08
Abstract: 308,122. Norton, H. F. June 8, 1928. Ventilators. - An air port frame 1 is provided with a windscoop comprising a plurality of interleaved plates 3 - - 6, the ends of which are pivotally mounted at opposite points within and on the frame. The width and shape of the plates are such that they lie wholly, or substantially wholly, within the frame when in folded condition. The relative move-. ment of adjacent plates is limited by the provision of a pic 7 on one plate for engaging an arcuate slot in the next outer plate. Stops 21, 22 provided on the plates 3, 6 are adapted to prevent the windscoop in closed condition from entering the port sufficiently far to interfere with the closing of the glass holder 2. The plates are pivoted centrally of the frame on bolts 9 provided with fixed non-rotatable sleeves 10, Fig. 5. A washer 17 having a sphericallyshaped lower surface is mounted beneath the lowest plate 6 so as to rotate therewith, and a non-rotatable washer 14 and spring washer 16 are mounted above the plates. Operating handles 18, 19 are provided on the plates 3, 6, a recess being provided in the glass holder 2 to accommodate the handle 19 when the plates are folded.

Abstract: 121,109. Loos, R. Oct. 16, 1918. Coupling.-The clamp consists of two pieces 1, 2 only, a pivot pin not being required. The piece 1 is angular in form and consists of a slotted base-piece 3 and a handle portion 4. The piece 2 is provided at one end.with an eye for attachment to the end of the rope, and at the other end with a broadened part 9, the edges 10 of which are adapted to form the equivalent of a pivot pin by permitting rocking about the point 7<1> after the pieces 1, 2 are assembled. The slot 5 in the piece 1 is enlarged at the end 6 to allow the stem 7 of the piece 2 to turn in it during the assembling of the pieces. A lug 110 is adapted to fit in the slot 5 to prevent the clamp from twisting. The rope is clamped between the end of the slot and an incline 11 on the lug 110. A strain on the rope straightens out the clamp and increases the friction nip. An upward pressure on the handle 4 releasee the clamp. The end of the broadened part 9 is notched at 13 to engage the rope.

The carcass is then returned to its central position and dropped onto a slide 350. The arms 320, V- blocks 220, spindles 100, 140 and carrier 270 mounting arms 236 are all powered by fluid motors with the movement of the V-blocks being synchronized by a rack and pinion arrangement. Safety mechanisms 330 prevent withdrawal of the spindles 100, 140 while the latter are supporting a drum and until the V- blocks are raised to engage the drum shaft. The pads 230, 232 grasp the carcass at the axial ends thereof and are moved into and out of their gripping position by the pivotal movement of arms 236 caused by fluid motors 288 synchronized by gears 280. The carriage 270 mounting the arms 236 moves on rails 260.
