Title: Improvements in or relating to handle locks for suction cleaners
IPC: A47L9/32
Filed: 1948-01-22
Abstract: 654,407. Suction-cleaner handles. EUREKA WILLIAMS CORPORATION. Jan. 22, 1948, No. 1974. Convention date, March 14, 1947. [Class 61 (i) ] [Also in Groups XXV and XXVIII] The body of a suction cleaner or the like has an upstanding handle pivoted for swinging movement from a parked position in one direction to an operating position and back to said parked position, a releasable locking mechanism automatically operable for locking the handle in parked position on its being swung thereto, the mechanism comprising a locking element on the handle, a locking member on the body arranged to engage the locking element to lock the handle against movement in the direction towards the operating position, and means actuated by movement of the handle in the other direction from the parked position for moving the locking member out of the path of the locking element to release the handle. A shaft 44, secured in the side plates of a handle socket 46, passes through bearings in the arms of a bracket 40 secured to the body of the cleaner 30. A cross-pin 50 in the handle socket co-operates with a latch 52, comprising two spaced parallel sides, pivoted in bracket 40 and biassed in clockwise direction, as seen in the figures, by a spring 56. The upper surfaces of the sides of the latch have notches 58 in which, when the handle is in vertical position (Fig. 1) pin 50 is engaged. Counter clockwise movement of the handle is then prevented by engagement of pin 50 against the sides of the notches, but slight movement clockwise depresses latch 52 to the position of Fig. 2, where it is held by engaging in a bend in a spring 62; the handle may then be rotated counter-clockwise to operating position. During this movement pin 50 makes contact with a horn 68 on the lever 52, and restores it to the position of Fig. 1. A torsion spring 70 coiled around the shaft 44 and bearing against pin 50 partially counter-balances the weight of the handle. A lever 72, Fig. 4, pivoted at 74 to the bracket 40 at a point outside the handle has a notch 78 adapted to receive a roller 80 and form a yieldable stop which determines the normal limit of the operating position of the handle.
Patent GB-229834-A (GB)
Title: Improvements in methods of casting metals and alloys
IPC: B22D27/04
Filed: 1924-01-24
Abstract: 229,834. Schwartz, H. A. Jan. 24, 1924. Moulds.-A mould used in casting metals is maintained within a constant range of temperature by automatically controlling the flow of circulating fluid through the mould in accordance with the temperature changes produced by the pouring in of the metal and' the subsequent cooling and ejection of the casting. The mould sections 1, 2, are'cooled by fluid which is drawn from a tank 6 by a pump 7 and after passing through the mould is returned through a cooling tank 14. The flow is controlled by valves 12, 13 which are actuated by means of a themostat 19 located in the mould. Thus when the temperature of the mould tends to rise as during the setting of the casting the valves are actuated so as to increase the flow of the cooling medium while as the temperature falls after ejection of the casting the valves are partially closed to reduce the flow of cooling fluid. Each thermostat element comprises a sealed casing A containing a loose piston D and an inner chamber B separated by a corrugated tube diaphragm E from an outer chamber C, the outer chambers containing the expanding fluid and being in communication with each other through a tube 20. The tube diaphragm of the thermostat 19, working against a relief spring is adjustable by a screw G to vary the rate of expansion of the fluid so that when the thermostat 19 attains a predetermined temperature the piston D in the member 21 causes. the valve 12 to be opened through the rod 22.

Title: Improvements in and relating to Perforating Machines.
Inventor: WILLIAMS ROBERT NEIL
Filed: 1915-02-15
Abstract: 100,150. Williams, R. N. Feb. 15, 1915. Selective punching-machines.-In a selective punching-machine for perforating record cards, such as are used in tabulating and sorting machines in which perforations are produced in fields or rows, means are provided, controlled by the setting or actuation of the main punches, for producing secondary or consequential perforations in a special field or row, and each corresponding in position to a field or row of main perforations and serving to indicate that a perforation has been made in such field or row. The invention is described in connexion with a power-actuated machine with special punches for producing the secondary perforations, and in connexion with a hand-actuated apparatus in which the secondary perforations are produced by the main punches. The power-actuated machine is of the construction described in Specification 23908/12, and comprises a series of rows of punches and a dieplate, upon which the card to be punched is placed, movable towards and away from the punches; above each row of punches is a slide provided with a projection which may be brought over the head of any one of the punches in the row, by manipulation of a corresponding key-slide, with the result that, when the die-plate is advanced, the punch, being locked, produces a perforation. In applying the invention, the upper surface of each slide is shaped and utilized to impart movement to a corresponding plunger, which in turn, by means of a bell crank lever, moves an horizontal slide over the head of the corresponding secondary punch. The main and secondary perforations are produced simultaneously. The hand-actuated apparatus is of the kind described in Specification 17299/06, and comprises a row of key-operated punches 43 and means for advancing the cord x transversely to the row after the operation of each punch. An auxiliary key 45 is provided, and upon this are pivoted spring pawls 48 and catches 50 corresponding in number to the main keys 41; the depression of one of the main keys, by means of an arm 55, liberates the catch and allows the spring pawl to engage with the hook 44 of the main key, which is thereby locked to the auxiliary key 45. This happens in turn for all the keys that are operated, so that after a series of main perforations has been made, the depression of the key 45 brings into action the whole of the punches which have been used to produce corresponding perforations in a row. The arm 55 corresponds in width to the distances between the punches, and it is mounted on a screwed spindle 53, which is geared to the card feed mechanism in such a manner that it is caused to move 'laterally to take up position for one key after the other.
