Granted: 1914-01-15
Abstract: 7012. Fairweather, W., [Underwood Typewriter Co.]. March 22. Sheet feeding and guiding arrangements; paper - shelves.-A front lay for alining sheets having perforations in the leading edge consists of pins on which the sheet can be suspended, the pins being retractable when out of use. The pin-controlling mechanism may be operated by the usual feed - roller release-key or may be provided with means of the following character for controlling front and bottom feed-rollers. In the arrangement shown, the pins 14 can slide in tubes 13 secured to a paper shelf 12; the pins being-pressed by springs 21 against cams 18 on a rock-shaft 16 provided with a finger-lever 15. The tubes are slotted to receive the cams, and are formed with extensions 17 which embrace the rock-shaft and prevent the shelf from sagging. Front feed-rollers 25 are carried by arms 26 which can slide for adjustment on a rock-shaft 28, the arms being formed with ears 30 which engage the shaft by a feather and are provided with friction-springs 33 bearing on the shaft. The shaft is provided with cranks 38 connected to slides 35 which are mounted on the tubes 13 and are held in engagement with the cams 18 by a spring 34. The cams 18 are formed with flats 24 adapted, when the lever 15 is depressed, to hold the pins in the projected position and the front feed-rollers in the released position. The bottom feed-rollers 6, 7 are controlled in the known manner by a finger-lever 39 connected by a link 41 to a rock-shaft 42 formed with flats engaging arms on the hangers of the feed-rollers. The bottom feed-rollers are released by depressing the lever 39 and can be restored by raising this lever, but preferably a device is provided whereby the raising of the lever 15 to retract the pins automatically causes the bottom feed-rollers and the lever 39 to be restored to the normal position. This device consists of a tappet 47 pivoted on an extension 49 of the link 41 and adapted to be engaged by a cam 46 on the rock-shaft 16. The tappet is formed with a tail 51 which is pressed by a spring against a lug 52 on the arm 49. The tappet yields to the cam 46 if the bottom feedrollers are released before the pins are projected.

Granted: 1914-08-07
Abstract: 18,447. British Thomson-Houston Co., [General Electric Co.]. Aug. 13. Drawings to Specification. Residual gases. - A tungsten-filament lamp contains a little nitrogen, or less preferably air, carbon dioxide, oxygen, or hydrogen, in addition to a compound called a ' getter,' exerting a regenerative action on the filament, such as potassium thallium chloride, cryolite, potassium iodide, or materials indicated in Specification 14,048/13. The pressure of the nitrogen should be less than 0À1 mm., and preferably lies between 0À01 and 0À05 mm. of mercury. In operation, metal scattered from the filament may be converted into nitride, which is decomposed by the ' getter.' For obtaining the nitrogenous atmosphere, a lamp is exhausted by a rough pump, then by a fine pump while heated to about 350‹ C., and then further exhausted at about 260‹ C. while half the normal voltage is applied. Dry nitrogen is then admitted up to a pressure of 0À1 mm. and is pumped out while the filament is incandesced, more gas then being admitted up to the desired pressure. The lamp may contain the ' getter ' retained by glass wool in a tubular central stem contracted at the tip. Specifications 24,973/06 and 15,621/10 are also referred to.

Title: Improvements in Apparatus for Heating Water and other Fluids.
Inventor: ANDERSON JAMES
IPC: F24H1/20
Filed: 1913-10-02
Granted: 1914-09-10
Abstract: 22,210. Anderson, J. Oct. 2. Actuating.-A part only of a bulk of liquid is heated to a predetermined temperature and then permitted to re-enter the main vessel, a fresh supply then occupying the heater, the intermittent operations continuing until the whole bulk is heated. The valve or valves governing communication between the heater and the main vessel are operated by an air chamber in the heater which sinks at lower temperatures but is buoyant at the predetermined temperature. The valve or valves may regulate the outflow of hot water from the heater or the inflow of colder water or both, and the sectional heater may be within or separate from the reservoir. Examples of these modifications are described. The Figure shows a practical adaptation of a separate heater. The hot water outlet 37 is controlled by balanced valves 38 operated by a float 41 open at the bottom and surrounding an inner air chamber or float 42 open only at the top. The outer float has weights 43 and a telescopic sleeve 44 for adjustment. In operation, the outer float and valves lift but the inner float 42 remains down until water enters the annular space between the floats and lifts the inner float also. Cold water flows in from the inlet 35, 36 and on reaching the floats the air contracts and the inner float rises until the flange 45 meets the shoulder 46 on the weight 47. Further cooling causes both floats to sink and close the valves. As the water heats up under the operation of the heater 56, for example an electric heater, the floats and the valves 38 rise again and the hot water escapes through the outlet 37. Provision is made for holding the valves down during adjustment, by a finger 55, the spindle 54 of which is hollow and can contain a thermometer The apparatus may be used in conjunction with or in place of an ordinary range-heated hot water supply system.

Filed: 1914-04-06
Granted: 1915-01-14
Abstract: 8715. Upham, B. F. April 6. Converting rotary into reciprocating motion.- Relates to bed-reciprocating apparatus, specially applicable to cylinder printing-machines, and in particular to the means for effecting the slowing- up and re-starting of the bed at the ends of the stroke. The bed is driven in one direction, namely, to the left in Fig. 1, by a wheel 27 which gears with a rack 24 on the bed, and in the other direction by a pinion 26 which gears with a rack 25 in a slightly higher plane than the rack 24. The wheel 27 is driven by gearing from the main shaft 18 and is in constant gear with the pinion 26, the w h e e l s being capable of a lateral movement together, under the action of a lever 32 and cam 37, into and out of engagement with their respective racks. The reversal of the bed at each end of the stroke is effected by means of shoes 41, 42 secured to the underside of the bed, and coacting with crank-pins 51, 55 rotating counter-clockwise and clockwise respectively. The shoes are formed with operative faces 45, 68 inclined at less than 90 degrees (preferably at 45 degrees) to the bed, and are provided with pivoted gates 46, 49 which are swung inwards to secure the crank-pins, while in operation, against the faces 45, 68, by means of fixed cams on the machine frame. In operation, the bed, moving to the left as shown in Fig. 1, causes the face 68 of the shoe 42 to contact with the crank-pin 51 rotating counter-clockwise, whereby the bed is arrested, the gate 49 at the same time swinging inward against the crank-pin, and the continued motion of the crank-pin re-starts the bed in the opposite direction. The faces 45, 68 being inclined as shown, the tendency for the bed to lift at each reversal is avoided, and the radius of the crank-pins may be less than the pitch circle of the gear 27.
