Abstract: 601,172. Electrically actuated valves. STEELE, W. R. July 9, 1945, No. 17493. [Class 135] [Also in Group XXXV] An electrically-operated, remotely controlled valve for use, e.g., in controlling the supply of pressure fluid to a motor &c., has a piston type valve-member 11 controlling a pressure fluid inlet 20, delivery ports 29 connecting with the motor, and exhaust ports 27, the arrangement being such that pressure fluid flow to the motor cannot take place until the exhaust port is closed. A solenoid 10 (see Group XXXV) having a polepiece 10a actuates a spring- loaded armature 9 connected, with lost motion, to a reduced upper end of the valve member. The valve member has an upper portion provided with grooves 18 for lubrication and a lower portion 11a, of the same diameter, for controlling the exhaust ports. Intermediate these portions are a conical lift closure 33 seating on an annular ledge 23 in a sleeve 12 and a piston type closure 34 whereby, upon upward movement of the valve member, pressure fluid cannot flow to the ports 29 until the closure 34 has moved out of its bore, when the portion 11a of the valve member will have moved sufficiently to close the exhaust ports 27. The area of the seating for the closure 33 is made greater than that of the bore in which the valve member operates, whereby the latter is retained, by fluid pressure, in the position shown in spite of vibration. As shown, the valves are arranged in pairs and are adapted so that a plurality of pairs may be assembled, having common aligned passages 21a, 25a for the pressure fluid supply and exhaust. In a modification, the upper grooved portion of the valve member 11 operates in a detachable bush and the lower end of the sleeve 12 has a flange engaging the housing, whereby the lower end of the valve member is isolated from exhaust pressure, a bleed opening being provided in a cap 32.

Title: Improvements in and relating to tube expanders
IPC: B21D39/10
Filed: 1926-07-13
Abstract: 255,121. Mihatsch, R. July 13, 1925, [Convention date]. Tube expanders.-A device, for expanding the ends of tubes in the walls of boilers or headers, of the kind having a number of expanding-rolls actuated by a conical roller operated by a threaded spindle driven manually or by a motor, comprises a casing, a nut mounted in the casing, a threaded spindle working in the nut and carrying the conical roller which actuates the expanding-rolls, a coupling cone rotating with the spindle but slidable thereon, a hollow cone adapted to be engaged by the coupling cone and a toothed pinion meshing with teeth on the nut and on the coupling cone whereby the latter automatically returns the cone spindle to inoperative position when the expansion is completed without changing the direction of rotation of the spindle. The expanding-rolls 3 are mounted, in a tubular extension 23 of the front cover 21 of the casing 2 and are actuated by the conical roller 4 on the end of the threaded spindle 1 working in a nut 5 mounted on the casing. The cone 9 is connected with the spindle by a key 11 engaging a groove 10 therein so as to have freedom for sliding movement, and is adapted to engage a hollow cone 12 having a toothed rim 15 mashing with a fluted roller 16 supported in the rear cover 19 and engaging teeth 6 on a flange 20 on the nut 5. A counter pressure spring 8 acts against a cap 7 formed with a conical friction surface 13 and provided with pins 22 engaging an annular groove 14 in the cone 12, the cap retaining the hollow cone 12 normally disengaged from the cone 9. Rotation of the spindle causes the conical roller 4 to move the rolls 3 outwardly to engage the inside of the tube, the casing 2 rotating at the same time so as to expand the end of the tube by a rolling action. The increasing pressure results in the movement of the nut 5 inwardly until, when the expansion has been completed, the hollow cone 12 is released from the friction surface 13 and clutched to the rotating cone 9, the teeth 15 on the hollow cone 12 then acting through the fluted roller 16 and teeth 6 on the flange 20 of the nut 5 to return the latter to its starting position.
