Patent GB-191114883-A (GB)
Title: Improvements in Stencil-duplicating Apparatus.
Inventor: MILLS CLAUDE KENNEDY
IPC: B41L39/08
Filed: 1911-06-26
Granted: 1912-04-18
Abstract: 14,883. Mills, C. K., [Dick Co., A. B.]. June 26. Stencilling-apparatus; tripping - a r r a n g ements.-Relates to stencil duplicating - apparatus of the kind in which the pressure roller is tripped at a certain part of the revolution of the stencil drum, and consists in the provision of a locking - member, moving under the control of two cams and a fed sheet, for preventing the tripped pressure roller from contacting with the drum in case no sheet is fed. The pressure roller 49 is carried by pivoted levers 25, and is drawn towards the drum 4 by springs 27 and tripped by a cam on the drum. A cross shaft 47 carries at one end an arm bearing on one lever 25 and at the other end a two-armed lever 48, one arm of which bears on the other lever 25 while the other arm extends towards a locking-member comprising a pin 46 on a link 43. This link is pivoted to a bent lever 40 pivoted at 41 and oscillated by a cam 36 on a shaft 13 driven by a train of gearing from, and at the same speed as, the drum shaft, and a stud 44 on the link slides in a slot 45 in a spring- controlled arm 32 which is mounted on a shaft 31 carrying a sheet feeler 29 and is oscillated by a cam 34 on the shaft 13. The sheets are fed over a table 19 between adjustable side guides and directed by a guide 53 between a series of upper feed rolls on a spring-mounted shaft 16 and a series of lower rolls 14 on the shaft 13, the effective or feeding portion 15 of the rolls 14 being of greater radius than the remainder. The sheets are fed up, while the feed rolls are not contacting, against front stops 18 carried by pivoted spring-controlled arms 20 oscillated by a cam on the shaft 13. So long as a sheet is properly fed, the feeler, which is drawn down by the cam 34 acting on the arm 32, prevents the arm from returning after the cam passes out of action, and the locking-pin 46 moves in a path clear of the end of the lever 48. When, however, no sheet is fed, the arm 32 after being acted upon by the cam is returned by a spring, and the locking-pin is brought below the end of the lever 48, which then prevents the pressure roll, after its tripping-cam has passed out of action, from rising into contact with the drum,

Granted: 1912-07-01
Abstract: 15,202. Robertshaw, F. W. June 29. Lift valves; actuating; regulating. - Valve apparatus for controlling the supply of gas to maintain a constant predetermined temperature in a water-heater comprises a lift valve 19, Fig. 2, operated by a diaphragm 16 when the gas pressure above the diaphragm has been released by an auxiliary valve 25 operated by the thermal bar 27 inside the water heater. Gas passes to the upper side of the diaphragm through a central opening 20 and thence by the pipe 23<a> to the auxiliary valve. When, however, the main valve is open, the diaphragm closes a chamber 21, whereby the flow to the auxiliary valve is restricted to the small aperture 22. The gas passing the auxiliary valve is discharged through the pipe 28 into the pilot burner tube. The auxiliary valve can be adjusted initially to obtain any predetermined water temperature by removing a cap 33 and turning the adjusting-screw 31 by means of a key having thereon an index pointer co-operating with temperature marks on the valve casing.

Abstract: 23,854. Sand, H. J. S., and Reynolds, F. Oct. 21. Leading-in wires. - Gas - tight seals for articles of vitreous material are made by running molten lead or a like plastic metal or alloy into the sealing position in a vacuum or an indifferent or a reducing atmosphere. The metal may form a plug in a vitreous tube, or may surround the outer end of a wire which has been sealed or inserted in a recess. Air pressure may be applied to the outer surface of the metal to ensure good contact. The vitreous material may be ordinary or quartz glass. The metal may be filtered through a capillary, and may be melted in a vacuum or in an indifferent or reducing gas which may be at a reduced pressure. Occluded gases may be removed by heating much above the melting. point. In the arrangement shown, a wire 1 of metal such as molybdenum passes through a constriction in a tube to be sealed. The outer end of the tube has a capillary constriction at 3 and contains above this a piece of lead 4, the tip 5 being closed. The tube is exhausted, and may then be collapsed or pressed upon the wire 1. The lead 4 is then melted and flows through the capillary part 3 into the space round the end of the wire 1, previously heated. On breaking the sealed tip 5, air enters and compresses the molten metal, into which a tinned leading-in wire may be introduced if the tube is cut at 8.
