Title: Improvements relating to apparatus for tempering steam
IPC: D06F71/34
Filed: 1947-11-13
Abstract: 629,738. Apparatus for tempering steam. EVERY, C. E. (Clover, Inc., B.) Nov. 13. 1947. No. 30230. [Class 86] An apparatus for supplying steam having different degrees of moisture content condenses part of the dry steam fed into it and distributes under pressure the dry steam and the condensate into separate compartments having an intercommunicating valve which controls the feed of condensate into the dry steam compartment so that dry steam or a moisture of the desired moisture content may be fed out of the unit by means of another valve housed in the steam compartment. A steam tempering unit 22 removably mounted in a pressure tight vessel 2 comprises a steam compartment 31 which is connected by a valve 54 to an outlet passage 32 which branches at 37 to an outlet port 38 having a nozzle 40. Part of the steam which enters the vessel 2 through a port 9 is condensed and condensate is maintained at a level 25 by an overflow port 14. Condensate flows under pressure into the compartment 30 through an orifice 44 in a disc 45 screwed into a tube 42 which is itself screwed into the lower end of the chamber 30. The disc 45 may be replaced by another having a different sized orifice. Spring-pressed valves 47, 54 co-operate with valve seats 33, 34 which encircle the bases of passage 32 and the chamber 31 respectively. The valve 54 is opened by a pivoted operating lever 67 and through a depending stem 56 subsequently opens the valve 47. Steam enters the chamber 31 through a part 46 of smaller size than the passage way 32 so that the aspirating effect of steam passing through the steam compartment when the valve 54 is open will add condensate to the steam in the desired amount when the valve 47 is subsequently opened.

Filed: 1921-11-14
Abstract: 190,606. Eikar Ges. Maschinen und Werkzeugfabrik, and Leineke, F. Nov. 14, 1921. Turning wood-screws.-Screw blanks are fed from a hopper a down a shoot comprising two parts c, m inclined in opposite directions with the object of presenting the blank to the machine in the correct position. The shoots are formed of two parallel bars the blanks e hanging loosely and being supported by their heads, and being allowed to escape individually from the upper part of the shoot by pins f, g intermittently reciprocated by a slide h<1> in the operation of the machine. the lower part q of the shoot is curved to partly surround the work support k, the upper side of the channel being slotted and formed with spring fingers r which retain the blanks. A spring pawl w carried by an extension v of an oscillating arm t carries the blank out of the spring fingers to the position b<2> whereupon the lateral movement of the support k places the head in the work-holder l. At the same time another pawl x turns a spring contiolled block z carrying a spring finger y away from the work support in which position it is held by a spring latch and projection. The cutting tool is then advanced and the relative movement between the tool holder and work support at the end of the cutting operation releases the latch and allows the finger y to grip the finished screw. The return movement of the work support pulls the screw out of the holder l, and the succeeding movement of the arm t to place a fresh blank in position also releases the finished article by turning aside the finger y. An arrangement suitable for a machine in which the tool is stationary and the thread cut by the traverse of the work-support and holder, consists in forming part of the lower shoot m' rigid with the upper shoot c. The part m<2> of the lower shoot is carried by the work-support and is adapted to receive individual blanks from the part m<1> which is provided with retaining pins g<1> actuated to release a blank when the part m<2> is vertically below. A plate 10 with pins r<1> may be secured to the underside of the shoot m<1> for tilting the blanks as required.
