Title: Improvements in gramophone records and methods of manufacture thereof
IPC: G11B3/70
Filed: 1928-06-12
Abstract: 319,038. Thornton, J. E. June 12, 1928. Coated fabrics.-Light, flexible, and unbreakable gramophone records are made. by impressing sound-grooves into a layer of chemically hardened glue or gelatine, which may be applied to a core or base of any suitable material, such as one or more sheets of paper. The colloid layer is applied to the base by flowing it on as a solution. An adhesive substratum is applied to the base or core before the colloidal face layer or layers are superposed thereon. A suitable adhesive mixture consists of a solution of glue in water, with the addition of alum as a hardener; for the record-receiving layer, a similar mixture, but with a greater proportion of glue (or gelatine) and with the addition of molasses, glycerine, or sugar as a flexing agent, is used. Suitable proportions of the. ingredients are specified in each case. The hardening is allowed to proceed for a long time before the sound-grooves are produced by means of a matrix, under heat and pressure or by pressure alone. The hardening agent, which may consist of chrome or potash alum, or of formalin, instead of being mixed with the colloid solution may be applied by absorption from a solution into the colloid layers before the latter begin to dry, or after drying, in which case further drying is necessary. Alternatively tbe colloid may be exposed to formalin vapour in a closed room. The flexing agent and the hardening agent may be combined in one bath, or applied separately. Several successive coatings may be applied, both for the adhesive substratum and the recordreceiving layers. The. material may be made in sheets, or as a continuous web which is afterwards cut up. One or both sides of a single sheet of paper may be coated with the celluloid layer; or two sheets may be cemented back to back before grooves are impressed on both outer sides simultaneously.

IPC: H02P1/18
Filed: 1919-07-10
Abstract: 155,614. Hirst, J. A., and Brook, P. S. July 10, 1919. Controllers, actuating-mechanism for; drum; handles; with auxiliary switches.-A controller handle is mounted in bearings in an angularly movable part; rotation about its own axis operates the control gear for the main-circuit switch and a reciprocating movement about the controller axis operates the starter to cut out resistance in a step-by-step manner. The sleeve 1<a> rotates on the fixed part 1 of the handle casing and carries the handle bearings 1<b>, 1<c>. A hollow shaft 3 carries claws 3a to engage the rotating part of the starter and also carries a ratchet 3<b> and an indicator 3<c> which is opposite the window 1<d> in the casing in the full on position. A pawl 4 is attached to the sleeve 1<a> and a cam 2d is fixed on the handle spindle 2. When the handle spindle is rotated in its bearings, the cam depresses a rod 5 with a head 5<a> to effect the closure of the switch D, Fig. 14, in the actuating-circuit of the main switch 19. In operation, the handle is first rotated to close the switch D and the main switch and an oscillating movement about the axis of the controller causes the operation of the starter through the pawl and ratchet. The controller may be held in the full on position by means of an electro-magnet 7e, which is energized to move a locking-arm 7 into engagement with a star wheel 6 on the spindle. In a modification, the surface of the ratchet in the ' full on ' position is higher than in the adjacent positions as shown in Fig. 9, and the pawl is lifted to engage a stop 10 on the casing. The ratchet surface may be lower in the ' full on ' position and the pawl then engages a stop at the side of the ratchet. The last tooth space before the ' on ' position may be half the pitch of the others, and the next operation moves the drum forward to the ' off ' position. When a drum controller is employed, the fingers may be constructed as shown in Fig. 13<b>. The pivot 26 of the finger 27 is carried by a bracket 25 which is bolted to the base-plate, with a bent plate 28, a laminated strip 34, and a cam-plate 35. The contact 33 is secured to the finger by a bolt 33<a> with a square dovetail head 33<c>.
