Hem-stiching machines; ornamental-sewing machines; presser lifted automatically.-A hem-stitch or other ornamental sewing machine having a universal feed is provided with a locking-device so that it may only be rotated between the groups of stitches. The needle-bar and perforator are reciprocated by a shaft 1, the needle-bar by a slide 14 embracing the needle shaft between collars 16 and actuated by a crank-pin 13, and perforator by a slide 4 engaging a grooved sleeve 7<1> attached to the perforator bar 7 and actuated by an eccentric rod 2. The work is held by a presser-foot 119 and a work clamp 123. The presser is attached to a grooved disk 114, and is lifted when a bell-crank lever 117 is actuated from a tappet on the cam 39 by a push rod 50. The work clamp does not rotate with the other device being mounted in the frame, and is lifted against a spring, by a bell-crank lever and pushrod from a second tappet on the cam 39. The needle holders 19, 20 are pivoted on the needlebar, and are caused to rotate about their pivots simultaneously by a pin-and-slot connexion between the lugs 19', 20'. They are rotated to open or close by a rod 27, which is attached to a lug 26 integral with the holder 20, when the rod IS carried round by a disk 21. The latter is caused to revolve by the vertical movement of a sleeve 23, a screw on which engages with a helical slot 21<1> in the disk. The vertical movement of the sleeve 23 is effected by a bell-crank lever 28, a link 32, and a cam actuated lever 31. The work-plate, feed-dog, and shuttle mechanism are revolubly mounted by means of a shaft 55. The shuttle is oscillated by an eccentric 89 on the shaft 1 through a lever 88, a sleeve 77, and cranks 80, 83, 86. The feed-dog is hinged to a pair of short vertically-arrangerl levers and is moved horizontally by engagement with a slotted lever ; the latter is actuated by a cam through a rod 44, lever 48, and a feather upon the shaft 55 oppositely disposed to a feather 58. The feed - dog is moved vertically by a bell-crank lever actuate by a cam 38 through a rod 46, lever 49, and the feather 58. The shaft 55 and the above-work devices are revolubly linked together by gearing 90, 93, 101, 102, 104, 106, 103, and 109. The system may be rotated by a hand-wheel 113 through gear 112. The system is locked from rotation by a pair of opposed detents 95. These are separated to free the system by a cam 36 and a rod 97. The cam-cylinder 36, 38, 39 revolves once for each group of stitches, i.e. in hem-stitching for every three stitches. A further device is shown for automatically rotating the system to produce a predetermined pattern. The shaft is rotated by the oscillation of a toothed sector actuated by a pattern cam-groove. The cam is rotated by a ratchet gear from the cam 36.

Abstract: 3935. Graham, E. A. Feb. 16. Telephone systems. -In a telephone system in which one or both of the supply lines possesses inductance, a resistance or resistances of a substantially non- inductive character are temporarily connected in parallel with the circuit or portion of the circuit which includes the transmitter of one instrument and the receiver of another instrument. I n Fig. 1, the transmitter a at station A is shown connected to a receiver b at station B, and a non-inductive resistance c is arranged across the supply leads d, e, the former of which includes an inductance d<1> in circuit with a switch a. Where a transmitter and receiver are provided at each station, the positive terminal of each transmitter is connected to the negative terminal -of -the receiver at the same station through a non-inductive resistance, so that three parallel circuits are obtained. The non- inductive resistance c may be put in circuit by the action of a relay as soon as either telephone switch is closed, or it may be put in circuit upon operation of either telephone instrument, a switch being employed at one station which simultaneously breaks the calling circuit and completes one speaking circuit. As applied to exchange working, independent supply leads, each including a choking coil, can he arranged for each telephone without any supply connexions being made through the spring jack, non-inductive resistances being used to complete the circuit. When the telephone switch k, Fig. 6, is operated, relay winding t is energized through a circuit from bus-bar s', choking coil d', wire d, switch k, resistance c, wires e, e', e<3> to bus-bar s. The ringing relay t is provided with spring contacts t<1>, t', t<3>, so that when the winding is energized, the bell x and lamp x<1> are connected in parallel across the bus-bars s, s', the bell circuit being completed from bus-bar s<3>, through conductor s', relay contacts t<1>, t<2>, conductor e, e', and bus-bar s, while the lamp circuit passes through conductor x', contacts t<3>, t', and conductor e', e. The exchange operator then inserts his plug into the jack, and having received instructions, places the plug w in the jack of the called station. The bell switch j<2> at station A is then operated and current flows from bus-bar s<1> through wire d, switch j<2>, wire v<1> which includes the speaking relay v, plug contact w', jack contact w<1>, conductor u, switch q<1>, bell r, wire e, and ring- ing relay t to the bus-bar s. If the switches k in stations A, B be now operated, circuits are completed through transmitter a at station A, relay v, contact w<2> of plug w, jack spring u<1>, conductor u, receiver at station B, ringing relay t to the bus-bar s, and also through transmitter a at station B, relay v, jack spring u', contact w<1>, receiver b at station A, relay t, and bus-bar s. The armatures v' of the speaking relays v by actuating contacts v<3>, v<4>, v<5> connect the supervisory lamps y across the bus-bars s, s' and short-circuit the ringing relays t.

Title: Improvements in Fluid-actuated Rock-drilling and other Percussive Machines.
Inventor: MAUSS WILHELM
Filed: 1907-07-01
Granted: 1908-07-01
Abstract: 15,120. Mauss, W. July 1. Rock drills.-In a rock drill or other percussive engine of, the kind described in Specification No. 27,496, A.D. 1906, in which constant pressure acts on 'the rear piston area, the return stroke being effected by intermittent pressure on a larger front piston area, the distributing-valve 16 is inside the piston 3 and is actuated by fluid pressure assisted by momentum. The piston - rod 29 is hollow and open to the atmosphere, and the rear of the piston is bored out and fitted with a hollow bush 8. This bush is turned down to form two annular ports 11, 12, and is bored out to form the valve chamber. In the position shown, live air enters holes 6, passes by ports 21, 22, 23, and 24 to the larger piston area 2, and the back stroke commences. The port 21 passing the shoulder 7 causes cut-off, the remainder of the stroke being effected by expansion. Towards the end of the stroke, the port 31 opens to pressure, and at the end of the stroke the port 35, which is larger than port 31, opens to exhaust through passages 36, 39, 38, and through the piston-rod; the valve 16 is then moved over. The front cylinder space exhausts through passages 24 and holes 20 in the valve and the working stroke is effected, the valve then being moved as before. If the forward stroke is unduly long, the shoulder 25 enters a recess 27, stops the forward motion by cushioning, and by reducing the effective front piston area automatically stops the drill. If the rear stroke is cut short by obstruction, the valve is moved over for a working stroke by the method described in Specification No. 27,496A, A.D. 1906. Specifications No. 5022, A.D. 1906, and No. 15,121, A.D. 1907, are also referred to.
