Abstract

624,190. Compressed air picks. ATELIERS DE CONSTRUCTIONS MECANIQUES ARMAND COLINET SOC. ANON. Feb. 10, 1947, Nos. 3850 and 3851. Convention dates. June 21, 1946 and Aug. 13, 1946. '[Class 124] In a compressed air pick, water under pressure is fed into a space 11 surrounding the body 1 of the pick and open on the side nearer the tool 3 so that the water leaving the space is projected into the neighbourhood of the tool. In the form shown, water from an inlet 7 passes through a passage 8 into an annular chamber 9 and through radial or inclined holes 10, 13, respectively. into the space 11. The latter is formed by a cylindrical casing 14, which may be separate from or integral with either the pick body 1 or the handle 5, and which is centred by abutments 17 and has a bell mouth 16. The kinetic energy of the water leaving the space 11 is increased by the pressure of the compressed air, preferably the exhaust air from the control mechanism 2, which may enter the space 11 through holes 12 up stream of the holes 10, 13. The admission of compressed air and water is controlled simultaneously by a trigger 6 through the intermediary of rods 22, 24, valves or balls 18, 19, and springs 20, 21. The supply of water is controlled by a needle 25. Two other forms of pick described and illustrated in the Specification each include a deformable airtight partition between the compressed air and pressure water circuits, and a modified control of the water supply.
