Abstract: 774,186. Retractive switches. HORSTMANN GEAR CO., Ltd. April 27, 1955 [May 3, 1954], No. 12768/54., Class 38(5) [Also in Group XXIX] A time - controlled mechanism applicable . to switches and valves has two setting members that can be moved together to set the duration of an operation, after which one of the members is displaced independently of the other to set a delay, both setting members being returned to normal by a clock mechanism so as to start and stop the operation. A knob 14 is attached to an arbour 13 which is connected to a spring 4 over gears 22, 23 and which carries a cam 17 co-operating with contact springs 6, 7. The arbour is normally urged to the left by a spring 21 so that a pin 26 carried by the knob 14 engages a hole in a setting member 27. Rotation of knob 14 to set the duration of the operation thus also rotates member 27, and a recess in the cam is moved away from springs 6, 7. If it is desired to delay the start of the operation, the knob 14 is pulled to the right to disengage 26, 27 and is further rotated to the desired extent, the end of pin 26 moving over the surface of member 27 and retaining the arbor 13 in its righthand position until spring 4 returns the knob 14 to a position where 26, 27 reengage, whereupon members 14 and 27 rotate together. A pivoted member may be attached to the cam to block the recess 20 if it is necessary to rotate the cam through more than 360 degrees during setting. A disc 16 coaxial with knob 14 is rotated to bring the setting time as shown thereon opposite a pointer 15 on the knob and the knob is rotated to bring the pointer 15 opposite the selected duration on a scale 29. When the knob is pulled out, it is rotated until pointer 15 reaches the finish time on disc 16. The disc 16 may be replaced by an annular scale surrounding the knob 14 (Fig. 7, not shown).

Title: Improvements in or relating to apparatus for feeding molten glass
IPC: C03B5/187
Filed: 1926-05-25
Abstract: 254,281. Hartford-Empire Co., (Assignees of Peiler, K. E.). June 24, 1925, [Convention date]. Delivering molten metal.-Relates to a feeder of the kind in which a rotary implement extends into the glass in the forehearth for stirring the glass prior to its discharge through an outlet. According to the invention, the implement is a tube surrounding the reciprocating plunger, and means are provided for directing cooling air adjacent to the bearing of the tube, and for facilitating the withdrawal of the tube from its bearing. The molten glass is contained in a forehearth 10, Fig. 1. and is discharged in " gobs " through an outlet 12 by means of a plunger 14, the flow of glass to the outlet being controlled by a tube 16 surrounding the plunger. The tube is rotated to stir the glass in order to obtain uniform temperature and viscosity in the " gobs," and the height of the tube above the outlet is adjusted by means of a crank 20 that raises or lowers the arm 17 by which the tube is supported. The tube is carried by a cylindrical member 28, Fig. 3, the upper edge of which is bolted to a gear ring 23 supported between ball bearings 24 in an annular housing 22. The tube is clamped in the member 28 by another cylindrical member 34 having lugs 36 which are bolted to the gear ring 23. By loosening the bolts, 37, the member 34 can be removed, thus enabling the tube 16 to be removed without disturbing its operating mechanism. The gear ring 23 is driven from a shaft 46, Fig. 1, rotated by a motor 45. The speed of the motor can be adjusted to suit the conditions of the glass and is independant of the means for operating the plunger. The lower portion of the housing 22 is arranged to form an annular chamber 42, Fig. 3, and air is blown into this chamber through inlets 43 and escapes downwardly through the space between the housing 22 and the member 28. The air thus supplied keeps the bearing cool and is given suf. ficient force to blow downwards against the cover of the forehearth, thus further protecting the mechanism from the heat radiated from the forehearth. A cable 53, attached to a counterweight, assists in supporting the weight of the. mechanism.

Title: Dry cleaning apparatus
IPC: D06F43/02
Filed: 1935-05-07
Abstract: A dry-cleaning apparatus consists of an horizontal perforated cylindrical drum 34, Fig. 1, rotating within a stationary casing 33 and provided with a door consisting of an outer circular member 36 and an inner member 41 which are spaced apart and move as one unit when being opened or closed.  The outer door member 36 seats against the edge of the drum extension 39, Fig. 4, and is secured thereto by a bridge member 56 engaging lugs 58 and is operated by a wheel 57 mounted on a screwed rod passing through the door.  The inner door is dished inwardly and seats against a tapered annular edge 43 of the inner rotating drum, corresponding in shape to the edge of the door. A rod 44 is secured at one end to the door 41 and the other end passes through a boss 45 mounted on the outer door 36, and is provided with a spring <PICT:0438331/III/1> <PICT:0438331/III/2> <PICT:0438331/III/3> 49 working against a perforated collar 48.  The spring assembly is lubricated through channels cut in the boss 45. The inner drum is thus permitted to rotate freely when the door is closed during cleaning operations.  The space between the door members is connected to a pipe 13 supplying warm air which passes through perforations in the inner door 41 to the washing chamber. Solvent such as trichlorethylene or carbon tetrachloride, is fed from a storage tank 26 to the washing chamber 34 containing the clothes. After cleaning the used solvent then drains into a sump 3.  A fan 10 forces air through a heater 12 and space 40 in the door member to the washing chamber.  Solvent vapours pass from the washing chamber to a condenser 5 and returns through a pipe 7 to the sump 3.  Finally cold air is forced into the washing chamber to deodorize the clothes. Solvent passes from the sump 3 to a still 20 and vapours pass through a pipe 22 to a condenser 24, from which condensed solvent flows through a water trap 25 to the storage tank 26.  The washing chamber, sump and storage tank are vented to the atmosphere through a pipe 29. During deodorization the clothes may be treated with a powdered moth proofing agent supplied from a tank 61 and carried by the stream of air to the washing chamber.  A fluid tight joint at the ends of the pipe 22 and for the water trap 25, is formed by a plate 71, Fig. 3, tapped to receive two studs 72 and having an annular seat to receive a gasket 73 which lies against the inner surface of the still, or tank 70.  With these parts in place an outer gasket 74 is applied and is secured by nuts 75 tightened against slots 78 cut in a flange 77 of the pipe 22.  The joint is sealed by a washer 79 lying in an annular seat of the plate 71.  The gaskets and washers are replaceable from outside the tank.
