Abstract: 637,190. Frictional pocket igniter. ORMESHER, A. H. May 23, 1947, No. 13912. [Class 75 (iii)] A frictional pocket igniter has a coiled compression spring g which presses against a flint at one end and at the other end has a stem h the free end of which protrudes from a guide tube f and bears against the base c<SP>3</SP> of a pressure-regulating cap member c slidably and adjustably secured upon the main casing a to vary the pressure of the flint k against the friction wheel. The main casing a and cap member c are provided with a series of equally spaced indentations and ribs c<SP>1</SP>, c<SP>2</SP> and a<SP>1</SP> to hold the lower cap in the adjusted position. The coiled compression spring g may be adjustably attached to stem h by having the lower coils g<SP>2</SP> closed together to form a screw thread of a pitch corresponding to that on stem h<SP>3</SP>, Fig. 6. Alternatively stem h may be provided with a collar h<SP>1</SP> which bears against the end of spring g, a sleeve washer i, and a steady pin h<SP>2</SP> which enters into the end of spring g, Fig 5.

Abstract: 163,705. Fabriques des Montres ZÚnith, (Successors of Fabriques des Montres ZÚnith G. Favre-Jacot et Cie). May 25, 1920, [Convention date]. Keyless mechanism.-The spindle T engaged by the square stem 10 of the operating knob is free to turn within and slide through the winding- wheel 21, and having its lower part squared, it carries a sliding clutch 22 with which the setting- pinion is united. The clutch is connected to the upper part of the spindle by a train of three levers 1, 2, 3 and, as shown, is thereby normally kept up in engagement with the winding-wheel. A disengaging pressure is exerted by a spring 4 behind the lever 2 but the operating-knob is held in by a suitable spring-and-slot stop device, till the hands have to be set. On drawing out the knob, the parts are left to the action of the spring 4. The lever 3 being set free, the clutch drops till the pinion gears with the setting-train 5. The lever 1 both raises the spindle T and locks the lever 3 in its new position. On pushing in the knob again, the condition shown is restored. A bolt A serves the same purpose when the movement is out of the case.

Abstract: 202,245. Pearson, W. May 4, 1922. Sewing - machines; presser bars w i t h periodic control; feed by presser feet. - The presser-bar and feed - mechanism are automatically regulated in accordance with the thickness of the work. The threaded hub 68 of a lever 69 is loosely mounted on a stud 67. Fig, 2, fixed to the casings, and is link-connected to a collar 71 on the presser-bar 72. A nut 73 is adjustably mounted on the hub 68, and the split hub of an arm 75 is adjustably clamped around the nut 73. The arm 75 is spring-connected to an arm 76x loosely mounted on a shaft 77 to which is fixed an arm 104, the end 174 of which bears on a block 153 on the presser-bar. A screw 110 adjustable in a lug 109 of the arm 76<x> bears on a lug 111 of the arm 104. The hub 74 of the lever 75 is limited in rotation by a screw 112. Fig. 2. A lever 170 pivoted on the threaded hub 68, Fig. 4 is oscillated by a cam so that it moves axially into locking engagement with the nut 73. Further rotation of the lever 170 acts through the lever 69 to lift the presser-bar. When the presser-bar is lowered under the influence of a spring 131, the hub 68 is turned in a clockwise direction, Fig. 2. The hub of the lever 170 and also the nut 73 are, however, held from rotation therewith so that their relative positions and therefore the lift of the presser-bar are unaltered bv alteration in the work-thickness. The shaft 77 is mounted in a short arm of a lever pivoted to the casing, the end 82, Fig. 5, of which extends in front of the casing. The movement of the lever 82 is limited by a stud on the casing engaging a slot therein. A link universally jointed to the lever 82 is pivoted at its other end to an arm 89 fulcrumed on the casing. A block 91 on the free end of the arm 89 engages a slot 92 in a link 93 pivoted to a lever 95 fixed to a cam-actuated shaft 96. In the block 153 on the presser-bar, Fig. 5, is slidingly fulcrumed a lever 155 to the lower end of which is secured the work-feeding member 156. A spring 159 connects the member 156 to an extension 103 of the link 93. To the block 153 are secured camplates 164 each having a slot 165 through which passes the securing-pin 166 for the member 156. A link connects the pin 166 and the member 103. Specification 201,997 is referred to.
