Abstract: 659,852. Door locks. SMITH, C. G. April 19, 1949, No. 10367. [Class 44] To render a door lock applicable to right- or left-hand doors opening inwardly or outwardly, the bolt is reversible, the key-hole comprises a pin hole located on the longitudinal axis of the lock and opposite slots extending at right-angles to this axis and alternative sets of locking tumblers are provided with means to render one set inoperative. In the form of Fig. 1, the bolt tail 13 is formed with an opening 25 to pass a key inserted in the key hole 2, 3, 4, and is slidably mounted' on symmetricallyplaced pins 14, 15. The tumblers 5, 6, are pivotally mounted on the pins 14, 15, and urged by a spring 16 to the locking position where lugs 7, 8 engage shoulders 9, 10 on the bolt tail. A cam member 20 pivoted on the longitudinal axis may be rotated to displace one or other of the tumblers to an inoperative position. The cam member 20 may be operated by a lug 23, Fig. 3, extending through a semi-circular slot in the lock cover or by an arm 37, Fig. 4, mounted to turn therewith and positioned outside the casing. As shown in Fig. 9, one tumbler 6 may be displaced by a rotatable disc 38 formed with a key-hole slot and secured by a screw 40. In another form one of the tumblers is displaced by a plate having a pair of spaced pins movable in a straight vertical slot with hooked ends. Both tumblers may be pivoted on a single pin located on the longitudinal axis. In the form of Fig. 12, a composite tumbler 43 has locking abutments 44, 45 engageable with a peg 46 on the bolt and biassed to one or other position by a spring 48 engaging lugs 51 or 52 on the tumbler and pins 54 or 53 on the casing.

Filed: 1926-04-20
Abstract: 254,661. Ezbelent, G., and Ezbelent, R. Jan. 28, 1926, [Convention date]. Pleating.-The lower roller may be given a partial rotation independently of the usual rotation for forming the pleats by means of a oneway device acting between consecutive pleats, thereby obtaining blank or unpleated areas in the goods between the pleated portions. The oneway device for giving a partial rotation to the lower roller 2 may comprise a cam operated roller 9, pivoted slotted link 6, link 5, pawl carrier 4, and ratchet wheel 3, which last is secured to the lower roller. A disc 18 rotated intermittently or continually is provided with a series of rollers 17, which are capable of engaging a pivoted spring pressed lever 13, and forcing it into the path of a hook 16 on the link 6, thereby preventing the operation of the ratchet wheel 3. As shown, one of the rollers is in inoperative position, having moved under the action of spring 24 from the operative position where it is retained by an enlargement engaging a flange 23 on the disc 18 but capable of passing into a corresponoing slot therein when turned through a right angle. The throw of the pawl on the carrier 4 is varied by varying the position of engagement of the surface of a cam 11 with the end of the link 5.

[Class 91] In apparatus for solvent degreasing metal &c. articles, the goods are raised or lowered therein by means comprising a counterpoise 11 adapted to travel in a vertical direction in a vessel 12 capable of containing a liquid such as water and being provided with means for supplying and withdrawing liquid therefrom at predetermined rates, the weight of the operating means varying between the weight of the counterpoise in air and its apparent weight in liquid. Water is supplied to the vessel 12 from a tank 15 through a valve 19 and withdrawn through valve 21, the valves 19 and 21 being inter-connected and hand or foot-operated so that when one is opened, the other is closed. This control may be effected automatically by inter-connection of the valves with the door 3 of the degreasing apparatus, which may be of the type wherein the door is arranged above condensing coils 4 for de-limiting the degreasing zone 1 upwardly. When the door is open, as shown, for loading or unloading the basket 7, the valve 19 is shut and the valve 21 open ; on closing the door the valves are reversed and the basket and contents are lowered for the degreasing operation. The water of the condensing coils 4 may be conducted to the supply tank 15. An orifice plate 22 allows of further regulation of the rate of flow of the water from the vessel 12. The heat supply for heating the solvent and the flow of condensing water may be respectively controlled by means actuated by the opening and closing of the door of the degreasing apparatus.

In the form shown, a spiral heating element 20 is mounted in a cup 21 at .the base of a plug 18 slidable in a sleeve 29 which is carried in a socket 19 at the base of a well 73. A ceramic plug 32 at the base of the socket 19 carries a pair of bimetallic arms 35 connected to one side of the secondary of a transformer, the primary of which is connected to the household mains supply through a switch consisting of arms 43, 44, the switch being operated by the end 53 of a lever 45 pivoted at the outside of the socket and having an arm 51 projecting through an aperture into the socket. The centre of the element 20 is connected to the transformer secondary via a rivet 23 in the plug 18, the outer end being connected to the cup 21. Pressure on the top 30 of the plug 18 causes it to slide in the sleeve 29 against the action of a spring 27 until the cup is engaged by the bimetallic arms 35, the movement also closing the switch 43, 44. When the element 20 is sufficiently heated, the arms 35 expand and release the cup 21 and the plug is then moved outwards by the spring 27 and may be removed bodily for use for lighting cigarettes &c. Outward movement of the plug also opens the switch 43, 44 to break the primary circuit of the transformer.

[Class 108 (iii)] Also in Group XVI] In apparatus for stacking cards or sheets in which cards delivered from a machine such as a tabulating-machine are allowed to accumulate in a pile 11 on a shelf 10 supported by a spring, the spring consists of a number of separate parts joined in series and connectors are provided whereby the shelf 10 can be detachably connected to the spring between any two parts thereof. By suitably varying the point of connection, the spring can be arranged to maintain the top of the pile at a constant level for different sizes of cards being delivered. As shown, the shelf 10 is attached to a spring 17 connected at its other end 23 to the upper end of a tube 20 secured at its lower end to the free end of a spring 16 suspended from a support 18 and having a similar stiffness to the spring 17. A pin 28 is secured to the lower end of the spring 17 and can be slid into a bayonet slot 27 in the lower end of the tube 20 when it is desired to render the spring 17 inoperative, i.e. when cards of twice the size previously dealt with are being delivered. The number of spring sections corresponds to the number of different sizes of cards to be dealt with, and their relative stiffnesses correspond to the relative weights of the cards. Compression springs supporting the shelf from below may be employed instead of tension springs.

Abstract: 549,408. Fluid-pressure servomotor-control systems. SCOTT, W. P., and WORTHINGTONSIMPSON, Ltd. Sept. 2, 1941, No. 11220. [Class 135] In means for controlling supply to feed water heaters comprising inlet and bypass valves, the former being open and the latter closed till a relief valve is opened, the relief valve is held closed by water pressure until released by means actuated by flooding of the heater casing. The inlet valve 23, Fig. 1, is carried by a piston 25 which has a valve surface 26 for controlling the bypass passage 22 and is normally retained in the position shown by pressure admitted to the cylinder 28 through a passage 29 having an adjustable control valve 30. When water rises to a predetermined level in a chamber 1 connected to the heater casing, a float rises to put a pressure liquid supply pipe 11 to exhaust through a pipe 10, thus reducing the pressure in a chamber 40 so that a spring 36 opens a relief valve 32, thus causing closure of the inlet valve 23 and opening of the bypass valve 26. The float in the chamber 1 is locked in its upper position and reset by a handle 1b. A battery of heaters in series may each have a float chamber, and a single unit comprising the inlet and bypass valves. Manually operated valves enable a faulty heater to be isolated.
