Abstract: 12,906. Macdonald, J. K., [Singer Manufacturing Co.]. June 6. Overedge -stitching machines; buttonhole -sewing machines.-Consists of means for forming a purl along the upper edge of an overseam or buttonhole stitching. Fig. 2 shows a front view of the head of the machine. The purling-looper 26, which co-operates with overedge-stitching mechanism of usual construction, is carried on a shaft 25 on which a pinion 27 is slidably keyed. The shaft 25 is reciprocated and oscillated from cams on the shaft by which the needle - bar is vibrated laterally, the oscillation being effected by a toothed segment gearing with the pinion 27, and the reciprocation by an angle lever 35 oscillated by a lever 37. The pin 38, Fig. 6, by which the lever 37 engages its cam, can be withdrawn from the cam in order to put the purling-device out of action. This is effected by means of a pin 53 and bayonet slot 52, and the pin 53, which lies within the machine arm, is of such a length that it can only be withdrawn when the looper 26 is in its highest position. The looper, Fig. 5, comprises two fingers 40, 41, the finger 40 carrying the purling-thread. In operation, the looper turns so as to stretch its thread between the two fingers, and the needle then descends within the loop thus formed. The purl is tightened by a take-up 42 operated by a projection 46 on the needle-bar.

Granted: 1903-11-26
Abstract: 15,831. Kleinschmidt, H. F. A. July 17. Welding; working by electricity.-An apparatus for electrically welding rail joints is carried by one or more cars running on the rails to be welded, and takes its current from the line conductor. Fig. 1 shows a diagrammatic view of the apparatus arranged to compensate for fluctuations in the line conductor to preserve a substantiallyconstant potential difference between the welding-terminals 38, 39. The current from the conductor 1 is divided to pass through the controller 4 of of the motor 5 for driving the car, and through the shunt and series windings 9, 10 of a rotary converter to convert the direct into an alternating current. The series circuit is provided with an ammeter 23, and a starting-switch 7, 8, while the shunt circuit has a switch 15 and rheostat 20. By opening the switch 15 and closing a switch 17, the shunt 9 is placed in circuit with a directcurrent exciter 14 driven from the converter and having series and shunt windings 12, 13. The primary coil 42 of a transformer 40 is connected to the rings 36, 37 of the rotary converter, and the secondary coil 43 carries the welding-terminals. The voltage of the primary circuit is regulated by means of two coils 49, 50 connected together and provided with a reversing-switch 51 by which the voltage may be raised or lowered, and with a dial switch 52 by which the amount of alteration may be varied by varying the length of the coil 49 through which the current passes. A switch 44 in the primary circuit is provided with an induction coil 45 having a movable core 46 with a flexible connection to the movable member of the switch. Springs 48 support the movable member and the plunger, the inductive effect of the coil being decreased or increased by raising or lowering the plunger. When the speed of the rotary converter exceeds a predetermined limit, a circuit is completed between stationary rings 29, 30 by centrifugally-acting arms on the armature shaft under the control of springs, the tension of which can be adjusted. The completion of the circuit breaks the main circuit at 26. In starting the apparatus, the starting-switch is gradually closed, the switch 15 being closed. When a volt-meter 21 shows a zero reading, the switch 15 is opened and the switch 17 closed, the voltage of the circuit 42 being then regulated till a volt-meter 22 shows the desired reading.

Abstract: 15,139. Lake, H. H., [Miller, T. S.]. July 6. Rope railways and tramways.-In an apparatus for loading and unloading ships and the like, the load can be conveyed to any point within a quadrilateral by giving it motion in three directions at right-angles. The load is suspended from a sheave h', Fig. 3, carrying a trolley which runs on the cable c, Figs. 2 and 3, stretched between the masts, and also carrying a pulley connected to a hoisting- drum which provides the necessary lifting motion. Two cables e, g, stretched between the ends of horizontal booms on the masts, are traversed by guide-pulleys in sheaves which are attached to the load by transverse ropes. To produce motion in one direction parallel to the length of the ship, the drum D simultaneously winds up three ropes which run parallel to the three cables, while at the other end of the vessel the hoisting-drum and a third drum pay out three similar ropes. The two cables from the third drum, which pass round separate winding-barrels connected by a friction clutch, also pass round pulleys i<1>, j<1> and are connected to the load. By regulating the clutching power between the drums, they can be rotated at different speeds, which gives the load a component motion at right-angles to the length of the vessel in addition to the longitudinal motion.
