Title: Improved motor drive for sewing machines
IPC: D05B69/12
Filed: 1924-10-22
Abstract: 223,917. Maimin Speed Control Corporation, (Assignees of Maimin, H.). Oct. 26,1923, [Convention date]. Gearing for stopping and starting machinery; variable-speed belt gearing.-Means for controlling the motor drive of a sewing-machine so as to permit of very low speed comprises a coned pulley in contact with which a belt is held by a belt-fork under control of an operator to vary the - speed by varying the amount of slip. In the arrangement shown a unit consisting of a base 5 supporting a control-treadle 8 and a standard 6 carrying a motor 7 is arranged in association with a sewing-machine 1. The spindle 10 of the motor carries a loose pulley 12 and a coned fast pulley 11 affording a slight shoulder 13 and having an annular part 14 with a groove 15. A belt-fork is mounted on the motor casing and comprises roller-carrying rods 21 guided in spring-containing pockets 19 and connected by a cross-bar 22. The belt-fork is moved against the action of the springs, to shift the belt 17 from the pulley 12 to the pulley 11, by means of a lever 26 connected to the treadle. The machine is started at very low speed by the slipping engagement of the belt with the shoulder 13, the slip decreasing as the belt is moved across the conical part of the pulley. A brake 31 is operated by the engagement of the upper rod 21 with a long lever 28.

Title: Improvements in or relating to internal combustion engine units, capable of being combined with similar units to form a multicylinder engine
IPC: F01B7/12
Filed: 1944-12-16
Abstract: 586,254. Multi-cylinder two-stroke engines. ROSE, J. F. Dec. 16, 1944, No. 25265. [Classes 7 (ii) and 7 (vi)] A two-stroke engine unit capable of being combined with other similar units to form a multicylinder engine comprises two stepped cylinders c, c<1>, in each of which a pair of opposed pistons reciprocate, the pistons being connected to a crankshaft N by connecting rods W, levers pivoted on shafts H and connecting rods R, which are arranged to be in tension during the expansion strokes. The annuli round the pistons are connected by passages D to spaces Z between the seats of doublebeat valves V<2>, V<3>. These valves are held against their seats by spring capsules B which are united to the valves and thus prevent leakage along the valve spindles, and opened by pivoted levers operated by cam grooves on discs on the crankshaft. Each double valve controls the admission of combustible mixture from a passage I and delivery of compressed charge to a storage chamber T and piston controlled ports in the other cylinder, exhaust ports E having already been opened by the opposed piston. The unit is rectangular in section to facilitate combination with other similar units, the shafts H being made continuous to assist in assembly. The Provisional Specification describes the use of a combined beat and piston valve instead of the doublebeat valve and crossheads and rollers instead of connecting rods W.

Title: Automatic control for sewing machines
IPC: D05B27/08
Filed: 1971-04-19
Abstract: 1343320 Feed variation, seams UNION SPECIAL MACHINE CO 19 April 1971 [26 March 1970] 25334/71 Heading D1G Sewing apparatus includes a workpiece drive control means sensitive to the disposition of a workpiece relative to a stitch forming region and adapted to control the effect of that drive means to vary the rate of displacement of the workpiece through that region independence on that disposition. As described, an overedge sewing is provided which automatically shortens the length of stitches provided at the two ends of a seam applied to a workpiece, the reduction in stitch length being achieved by raising the throat plate 12f to reduce the time during which the usual feed dog is in effective contact with the work. The throat plate 12f is secured to a member 12h slidable vertically in a groove in a block 13a secured to the machine frame. A shaft 13d rotatable in a block 13b carries a pin 13e having a head which engages a recess in the member 12h. An arm 13g connected to the shaft 13d is connected by a chain 13k to a pneumatic actuator 20; when the latter is energised through a solenoid operated valve 37 the shaft 13d is rotated to raise member 12h and its throatplate 12f to reduce the stitch length. Valve 37 is actuated by signals from an electronic network (Fig. 18) which includes photoelectric cells 10, 11 normally illuminated by a lamp (16, Fig. 13, not shown) but disposed in the work plate (13, Fig. 12, not shown) to be covered or uncovered by work being sewn. The network comprises a first system I controlled by P.E. cell 10 and a second system II controlled by the P.E. cell 11; each network controls an S.C. Rectifier 53a, 53b disposed in series with the solenoid 37b of valve 37, and each comprises a Schmitt trigger 60, 60-1 and a time delay circuit. The arrangement is such that system I is operative when cell 10 receives no light and system II is operative when cell 11 is illuminated. Work introduced to the machine for sewing first covers cell 11 only and neither system is operative. When the machine is started by the operator's pedal (32, Fig. 13, not shown) the work moves to cover cell 10, and system I operates to energise its time delay circuit and maintain S.C.R. 53a and the valve solenoid 37b energised for a selected period to raise the throat plate and provide close stitching at the beginning of the seam. Variable resistor 43 is used to select the duration of the close stitching period, after which the valve 37 is closed, the throat plate falls and normal stitching continues. As the end of the seam approaches, cell 11 is uncovered and a similar cycle is initiated, by system II.

Convention date, Sept. 11, 1931. [Class 7 (iii).] In a Diesel engine having a pre-combustion chamber c through which the main supply of fuel is projected and one or more nozzles a which deliver directly into the engine cylinder, the main supply during normal running is regulated in accordance with the load. The supply of fuel through the nozzle a may remain constant or it mav increase in the same ratio as the fuel supplied to the pre-combustion chamber nozzle. In the construction shown in Fig. 7, fuel is supplied to the nozzle a and to the precombustion chamber c by pumps d, e which are driven by cams k, in adjustably mounted with a governor n, on an engine-driven shaft o ; the cam m is formed integral with the governor sleeve q. When idling, the engine speed may be controlled by adjusting the position of the cam k through a hand-lever r. The cams are designed so that no fuel is delivered through the pre-combustion chamber at low speeds whilst all the fuel is delivered therethrough at high speeds. The fuel supply to the precombustion chamber and to the nozzle a may be delivered by a single pump. The pre-combustion chamber and the nozzle a may both be located in the cylinder head or in the cylinder wall at the opposite ends of a diameter ; or the injection nozzle may open obliquely into the cylinder. The Specification as open to inspection under Sect. 91. also states that a pump having a stepped piston may be used. This subjectmatter does not appear in the Specification as accepted.
