Title: Improvements in glass building blocks and method of making them
IPC: E04C1/42
Filed: 1935-04-15
Abstract: 439,401. Moulding synthetic resin surfaces on glass blocks. CORNING GLASS WORKS, Walnut Street, Corning, New York, U.S.A.-(Assignees of Gray, D. E.; 1, Catherine Street, Corning, New York, U.S.A.) April 15, 1935, No. 11645. Convention date, May 21, 1934. [Class 87 (ii)] [See also Group X] A transparent glass building-unit is formed by applying a sheet of resin to at least two opposite edges of the glass block such that the outer surfaces of the resin are a predetermined distance apart, thereby covering surface irregularities, and providing blocks having constant dimensions. Polymerized vinyl acetate may be used. The thickness of the resin sheets should be about equal to the average variation in the glass blocks. The sheets are somewhat larger than the surface of the block. They are pressed against it by movable platens 10, 11 which are heated by steam from conduits 21. The resin is softened and the platens are pressed further against the block. When the platens have been moved so that they are the required distance apart, they are stopped and the resin is cooled and hardened by admitting cold water through pipes 25 to the platens which are then moved apart. Sticking may be prevented by placing a thin sheet of the material known under the Registered Trade Mark " Cellophane " between each platen and the resin sheet. The projecting edges of the resin are trimmed off. The glass block may be taken warm from casting. Shafts 30, 31 pass through bosses 28, 29 on the ends of the platens. The bosses 28 are fixed to the shaft between a shoulder and a collar, and the bosses 29 and corresponding parts of the shafts are screwthreaded. The platens are thus relatively moved by rotating the shafts, as by cranks 36 ... 39 and links 40, 41. The cranks 36, 37 may have counterweight portions 43. The movement of the platens is limited by stops fixed on the table and by sleeves 35 on the shafts. The sleeves are equal to the thickness required for the finished block. The platens have polished faces and may be contoured such as with a tongue and groove to correspond with the block. Screws passing through the table are provided to level and support the block. Specification 439,402 is referred to.

Abstract: 454,032. Prepayment mechanism for meters. CHAMBERLAIN & HOOKHAM, Ltd., and JAMES, S., 4, New Bartholomew Street, Birmingham. April 18, 1935, No. 11959. [Class 27] Price-changing mechanism.-In a prepayment meter, means whereby the rental charge, the quantity of commodity available for a given coin, or like charges controlled by the meter may be varied, comprises a driving spindle a, rotated through wheels d, c, b from a motor, clock, or coin carrier, the spindle a being axially slidable under control of a spring e and carrying a clutch disc or arm f which is provided with oppositely directed lateral projections g, m. The projection g co-operates with a stationary adjustable cam h and the projection m engages intermittently a projection n on a gear wheel o, loose on the spindle a, but controlled by a spring p which tends to keep another projection v on the wheel in contact with a fixed stop w. The wheel o engages and drives a wheel q loose on a driven spindle r from which motion is transmitted through a wheel u to the valve, switch, &c., control mechanism of the meter. The wheel g drives the spindle r by a oneway pawl and ratchet drive s, t, backward rotation of the spindle being prevented by a pawl and ratchet 2, 3. The spring e tends to slide the spindle a so that the projection g moves into an inclined notch i in the cam h. During rotation of the spindle a, the projection g moves out of the notch, pressing the spindle a backwards until the projection m comes into the path of the projection n so that the wheel o is rotated and drives the spindle r. When the projection g again comes opposite the notch i, the clutch is disengaged and the spring p returns the wheel o until the projection v again comes up against the fixed stop w, the pawl s during this return rotation moving idly over the ratchet wheel t. The cam h is adjustable by a key inserted in a boss j, backward rotation of the cam being prevented by a pawl l engaging a ratchet wheel k. By adjusting the cam, the fraction of a revolution of the disc f during which the projections m, n are in engagement may be varied.
