No. 25409.—6th January, 1909.—BRITISH FIXATOR, LIMITED (a company duly incorporated according to English law), of 73 Moorgate Street, London, England (assignee of Leopold Benoit de Laitte and Harold Mark Carter, both of 73 Moorgate Street, London, England). Improvements in the means for preventing accidental movement of rotating parts.

Claims.—(1.) Means for preventing accidental rotation of parts capable of rotating consisting in a helix fixed at one end and free at the other end and so arranged that accidental movement will cause it to bind, thereby preventing transmission of such accidental movement, and binding of the helix is prevented by holding the free end which permits intentional movement. (2.) The combination of a part capable of rotation, such as a nut or the like, having a portion surrounded by a helix, one end of which helix is fixed to a non-rotating part, substantially as and for the purpose set forth, and as illustrated in Fig. 3 of the drawings. (3.) A helix constructed and operating substantially as illustrated in Figs. 1 to 3, and combined with a piece capable of rotation as and for the purpose specified. (4.) A helix substantially as illustrated in Figs. 1 and 2 combined with a non-rotating part, a loose rotating part, and means for operating the loose part, such operating means being adapted to cause or permit rotation of the loose part, all so arranged that movement of the operating part is transmitted by a loose part to a device to be actuated by the whole, whilst accidental movement of the actuated part is prevented by the effect of the helix, substantially as specified, and as illustrated in Figs. 6, 6A, and 7. (5.) The combination of two helices of opposite inclination with an operated part and an operating part, the whole so arranged that the operating part may cause movement of the operated part in either direction, and that no movement of the operated part can take place accidentally, substantially as specified, and as illustrated in Fig. 8.

The improved ventilator and ridging for buildings specified consisting of the crescent-shaped top with the ordinary flange projections, said crescent-shaped top having portions of it cut out at intervals so as to make openings therein, and cap held over said top and openings by straps fitted internally to said cap in such a manner as to leave an open space between said cap and said flanges, and means for adjusting said ventilator and ridging to building constructed in the manner and for the purpose set forth as described and illustrated. (2.) In the improved ventilator and ridging for buildings specified, the openings made in the crescent-shaped top for the purpose set forth as described and illustrated. (3.) In the improved ventilator and ridging for buildings specified, the straps fitted internally to cap for holding said cap over top and openings therein in the manner and for the purpose set forth as described and illustrated.
