Title: Improvements relating to Volt-Ampere Meters or Direct-current Wattmeters
Inventor: GENERAL ELECTRIC CO
Filed: 1902-05-24
Granted: 1903-04-09
Abstract: 11,850. Lake, H. H., [General Electric Co.]. May 24. Energy meters.- A hot-wire instru- ment is constructed as shown to measure apparent power, the product o f current and pressure, on any circuit. It is ap- plicable as a con- tinuous-current watt-meter. Its indications may be compared with those of an ordinary watt-meter, on an alternating- current circuit, to give the power factor. A frame, Fig. 4, consisting of two straight guides 3, 3<1>, two end-pieces 4, and two pivots 6, turns in stationary bearings 7, Fig. 1, under the action of a hot-wire 9, which extends from stationary supports 8 to oppo- site sides of one pivot 6, passing through a dia- metrical hole in the pivot. An ivory or other non-conducting slider 13, Fig. 4, is movable along the guides 3, 3<1> by a second hot-wire 12, in oppo- sition to a spring 14, the wire 12 and spring 14 being carried by the end-pieces 4. The slider 13 is also connected to a cord 21, Fig. 1, which is wound on the axle of a pointer 26, and is tightened by a spring 24, acting on this axle. The two wires 9, 12 carry the main current and pressure respec- tively, connection with the wire 12 being made through the spring 14 and two flexible spiral con- ductors 16 on the pivots 6. The thermal expansion of the wire 12 allows the slider 13 to move to one side of the pivots 6, and expansion of the wire 9 then allows the frame 3, 3<1> to be turned and the cord 21 to be moved by the spring 24, the pointer 26 being thus deflected over a stationary scale- plate 27. The base 1 is made of metal with the same temperature - expansion coefficient as the wires 9, 12.

Patent GB-190213668-A (GB)
Title: Improvements in the Automatic Regulation of the Upward Speed of Hydraulic Press Rams more Particularly Applicable to Metallurgy.
Inventor: HARMET HENRI
Filed: 1902-06-16
Granted: 1902-10-09
Abstract: 13,668. Harmet, H. June 16. Ingots.-Relates to means for regulating the speed of press rams, especially such as are used in metallurgical operations. Figs. 1 and 3 show the invention as applied to a press for compressing steel in ingot moulds. A pipe 6 leading from the pumps, and a pipe 9 leading to the press cylinder, open out into a chamber 7, in which is a needle valve 10 controlling the supply to the press. The valve is coupled to a shaft by means of a connection 11, which leaves the shaft free to turn without moving the valve. The shaft is provided with guide-washers mounted in bearings, and it has a screwed portion 15 engaging a thread in a pinion 16 and a squared portion 17 engaging a corresponding hole in a pinion 18. A weighted rack 21 engages the pinion 16 and is connected to the press ram by a rope 25, and a rack 20 engages the pinion 18 and is connected to a ram 2 working on a cylinder 1. This cylinder discharges at a constant rate through an orifice 5 controlled by a valve 4. The cylinder 1 is normally filled with water, and when it is desired to raise the press ram, the valve 4 is opened. The fall of the ram 2 causes a rotation of the shaft, and the pinion 15 acts as a nut to withdraw the shaft and open the valve 12. Immediately the press ram begins to rise, the pinion 16 is rotated, and the position of the valve 10 is so controlled by the differential motion of the pinions 16, 18 that a uniform velocity of movement of the press ram is obtained. The racks 20, 21 can be moved out of, or into, engagement with the pinion by means of screws operated by crank-handles 22, 23. When the rack 21 is out of engagement with the pinion, a claw 24 engages the teeth of the pinion, which acts as a nut to allow the valve to be moved by hand by means of a crank-handle 19 on the end of the shaft.

Title: Improvements in Ticket Punches.
Inventor: MCNUTT WILLIAM ALEXANDER
Filed: 1902-09-26
Granted: 1903-06-18
Abstract: 20,967. McNutt, W. A. Sept. 26. Ticket punches.-Upon inserting a ticket in the slot e, the pin e<2> is depressed, and the end of the lever G is lowered until the nose g<1> is clear of the punch-guide E, so that the punch B may be pressed forward by the thumb-lever C to punch the ticket. As the lever G is carried forwards with the punch B, the projection g<4> moves forwards by one tooth the ratchet H' of the train of wheels H<2>, H<3>, H' for indicating the number of tickets sold, and the consequent movement of the detent K actuates the hammer L of the bell signal The ticket stampings fall between the plates M, M' into a receptacle, which may be readily attached to the body of the punch. Should the punch be moved sufficiently far forwards to punch a ticket but not to affect the indicator, the nose g<2> of the lever G, on the return movement of the parts B, G, abuts against the stop g<3> and locks the punch, so as to block up the lower part of the slot e. When a ticket is again inserted in the slot e and the thumb-lever C is depressed, the indicating- mechanism completes its movement without punching the ticket. The car conductor must then punch the second ticket correctly, whereupon the indicator records the two tickets. A detent K prevents the toothed wheels from being moved forwards to record more than one ticket at a time.

Title: Improvements in or relating to Means for Regulating Pressure in Air or Water Pumps
Inventor: SPERY CHARLES FRED
Filed: 1902-11-10
Granted: 1903-01-22
Abstract: 24,596. Spery, C. r. Nov. 10. Governing or controlling pumps; ; electricallyactuated pumps.-The supply circuit of an electric motor 4 driving a pump 3 by means of a belt 45, a wheel 5, a connecting-rod 8, and a piston 7, is made and broken as the diaphragm 19, one side of which is connected to the pipe line 9, 10, falls and rises. The top 18 of the diaphragm casing carries a casing 20, to which are attached a binding- screw 43 and a fixed insulated contact 36 forming part of a binding-screw 35. The diaphragm carries a rod 21, which is adjustable by a spring 29 and a screw plug 23. The rod is attached to a bracket 25 to which is pivoted an arm 27 having a wedgeshaped lower end, acted upon by a spring 28 adjustable by a screw plug 26. To the casing is pivoted a bell-crank lever 30, having a wedge-shape end 31, a hardened contact point 34, and an extension 32 facing an adjustable set-screw 33 acting as a stop. When the diaphragm rises, as shown in full lines, the end of the lever 27 is above that of the point 31, and the lever 27 being pushed inwards by the spring 28, the point 34 is forced away from the contact 36. When the diaphragm falls, the end of the arm 27 passes below that of the bell-crank lever, and forces the other end of the latter against the fixed contact, thereby completing the circuit from 38 through wire 37, screw 36, casing 20, screw 43, wire 42, screw 44, motor 4, screw 40, wire 39, and contact 41 of the supply. By the construction shown, sparking at the contacts is prevented. The whole device is fixed upon a base 1.

Title: Improvements relating to Alarm Apparatus in connection with Automatic Sprinklers for Extinguishing Fires.
Inventor: GRIMSLEY JOSEPH GARRATT
Filed: 1902-11-17
Granted: 1903-09-17
Abstract: 25,228. Grimsley, J. G. Nov. 17. Alarms, fire; sprinklers, automatic.-The automatic sprinkler described in Specification No. 472, A.D. 1902, or like apparatus for extinguishing fires, is combined with an alarm apparatus actuated by the reduction of pressure in the pipe system due to the opening of a sprinkler. The apparatus may work on the wet or dry system, or a combination of both. In the dry system, the valve chamber 1, Figs. 1 and 3, is connected to the water main 2, the sprinkler supply pipe 3, and a water motor 6 having'arms which strike an alarm-bell 7. The main valve 8 carries a smaller valve 9, which is prevented from rising by means of a lever 11, Fig. 4, controlling the motor supply valve 13 and regulated by a spindle 24. A lever 15, bearing on the lever 11, is connected to a counterbalanced piston 16, Fig. 3, held against the air pressure in the pipe 17<a> by means of a strut 18<d>. The air is compressed by operating the lever 19<c>, and passes by valves 20 to the pipe system. If a sprinkler opens on an increase of temperature, the pressure in the pipe 17<a> falls and allows the water pressure to lift the main valve 8 and motor valve 13. Pressure and level gauges are fitted as shown. The dry system described above may be used as a wet system by opening to the atmosphere a tap 20<@>, Fig. 1, on the air pump, and adjusting the screw 13<b>, Fig. 4, the water pressure in the system being the same as that of the supply.

Title: Improvements in Rotary Take-ups for Sewing Machines
Inventor: FAIRWEATHER WALLACE
Filed: 1903-06-30
Granted: 1904-05-05
Abstract: 14,512. Fairweather, W., [Singer Manufacturing Co.]. June 30. Sewing - machines, governing needle thread in.-Relates to a rotary take-up arm in which the thread moves in and out for the thread-slackening and stitch-tightening operations, as described in Specifications Nos. 14,549 and 15,243, A.D. 1901, and No. 12,903, A.D. 1902. A rotary takeup arm 15, attached to a disc 1 mounted on a shaft 14, consists of two plates, provided with a finger 17, between which plates is pivoted a tbread-detaining lever 18 operated by a stationary cam, as described in Specification No. 12,903, A.D. 1902. A hollow guard ring 20 serves to prevent the escape of the needle-thread and is a protection for the machinist. The stitch is tightened as the arm 15 ascends and slackening commences as the thread slides down the face 4, on the take-up arm, after it has passed the horizontal position. A shoulder 16 momentarily detains the thread and then moving down lets it off at about the same speed as the descent of the needle. As the needle loop is taken by the hook or shuttle, the thread slips from the shoulder 16 and provides the requisite slack thread. The position in which the thread is fully slackened is reached when the arm 15 is at its lowest, and the thread has escaped from the ledge 2 between the take-up arm and the disc 1, in readiness to be again caught by the outer end of the arm as it rises to perform the take-up operation. If the thread becomes broken, as it is carried round, the broken end is caught by an in-threading guard 21, at its point 22, and wound round it, being thus instantly withdrawn or unthreaded from the rotary take-up. This device is out of the normal path of the thread and only comes into contact with it when broken.
