Title: Improvements relating to Cutting Devices used in Machines for Making Paper and like Bags.
Inventor: HENDERSON JOHN
IPC: B31B23/00
Filed: 1912-01-31
Granted: 1913-01-30
Abstract: 2488. Henderson, J., Henderson, A., and Henderson, D. Jan. 31. Pivoted-blade type.-In machines for severing printed webs of paper &c. into lengths for the manufacture of bags, the cutting-device is so mounted as to be adjustable longitudinally of the web to ensure accuracy in the position of the line of severance. A revolving blade A, which coacts with fixed blades G, K, is splined on a spindle B and is adapted to be adjusted longitudinally thereon by a forked lever C, which embraces the hub of the blade A and is traversed longitudinally by a hand-operated screw spindle H. The lever C is also connected with a plate or table F carrying the bag-folding appliances (not shown) and the dead knife so that these members participate in the adjustment of the blade A. In a modification, the table F and spindle B are adjusted simultaneously by hand - operated rack and pinion gearing on the table, the blade A in this case being secured to the spindle B.

Title: Improvements in Arrangements for Accelerating the Variation of a Magnetic Field in Dynamo-electric Machines.
IPC: H02P9/12
Filed: 1912-02-20
Granted: 1912-06-20
Abstract: 4283. Allmõnna Svenska Elektriska Aktiebolaget. Feb. 24, 1911, [Convention date]. Exciting.-To accelerate the variation of a magnetic field, a current induced by this field in a winding is caused to vary the excitation of one or more dynamo - electric machines which regulate the strength of the field. In one arrangement, Fig. 1, the field F of an alternator or other dynamo - electric machine, which can be subjected to variation, is generated by a winding L1 supplied by an exciter M, which may be shunt-, series-, or separately - excited. the field magnet of the main machine is provided with an additional winding L2, and the current induced in the latter by the variation of the field F is conducted to an auxiliary field-magnet winding f1 of the exciter M. The resulting voltage variation of the exciter M serves to compensate for the electromotive force of self-induction induced in the winding L1 by the variation of the field F. In modifications, the winding L2 may be connected in series with the exciter field-magnet winding f, or the current induced in the winding L2 may excite the field-magnet winding of a booster, the armature of which is inserted in series with the armature or field - magnet winding of the exciter M. To hasten the regulation, the booster or its exciter may be provided with a second field-magnet winding connected in shunt to its terminals. The Specification as open to inspection under Section 91 (3) (a) states also that the abovedescribed arrangements may be modified so as to retard the variations of the magnetic field; this subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the Treatment of Iron.
Inventor: DISMORE ANGELO VACANI
IPC: C25D9/04
Filed: 1913-02-19
Granted: 1914-05-19
Abstract: 4292. Dismore, A. V. Feb. 19. Iron, obtaining; metals, pickling; connexions. -Cast or wrought iron, or inferior mild steel, is rendered more malleable, ductile, and tenacious by constituting it an insoluble electrode of a bath in which the electric pressure is increased or diminished, preferably suddenly, during electrolysis, being for part of the time considerably higher than ordinary plating pressures. The lowest pressure may for instance be 6 volts, and the highest pressure 250-1000 volts. In the arrangement shown in plan, two pairs of anodes F, of nickel and carbon respectively, are suspended on opposite sides of the iron cathode E. Before changing the pressure the iron is reversed, so that each side faces the nickel and carbon electrodes in succession. Low and high pressure circuits C, D are both connected to the electrodes; the high-pressure circuit includes a hand-switch D<1>, and the lowpressure circuit an automatic switch C<1> which opens under the action of the higher pressure. The electrolyte may be made by boiling 3-4 quarts of water with 35¢ oz. nickel sulpha.te, 26¢ oz. neutral ammonium tartrate, and 77 grains tannin, diluting to 20 quarts, adding first a solution of 0À35 oz. nickel ammonium sulphate and 1À75 oz. strong ammonia, in 1 quart of water, and then successively, to each gallon of liquid, 1À25 lb. common salt and 3À75 grains platinum bichloride. Alternatively, 1 lb. of " nickel salts," i.e. a mixture of nickel sulphate, ammonium tartrate, and tannin, together with the amounts of common salt and platinum chloride specified, may be dissolved in 1 gallon of water; this electrolyte may be revivified when required by adding nickel ammonium sulphate, ammonia, and water. The cell may be of lead lined with matchboard, and is preferably constructed so that the electrolyte may be agitated and may be heated by gas or electricity, or otherwise. Before treatment the iron is freed from grease, paint, and the like, and after treatment it is washed in boiling water.

A pantograph 3 controls workholders 5 through a bar 4, and the machine shafts 1<Î> are connected with a shaft 9 through helical gears in capped oil baths 8 secured to the machine heads 1. The shaft 9 carries a clutch disk 11 having a leather ring 13 adapted to engage the face of a driving- pulley 16 loose on the hub of the disk 11, and normally held away by a spring placed between the end of the shaft 9 and a cap 20 on the pulley boss. The spindle hub carries a collar 38 connected thereto by a pin on the collar passing into a concentric slot in the hubs and engaged by the ends of springs, the other ends of which bear against another pin secured to the disk 11. The collar 38 has a broken flange adapted to be entered by a trip 40 on one arm 26 of a threearmed lever 23, another arm 24 of which carries a resilient nose-piece 37, and the third 25 carries a pin 31 engaged by a roller 27 on a bell-crank lever 32 operated from a treadle.

Abstract: 3267. Fairweather, W., [Singer Manufacturing Co.]. Feb. 7. Sewing-machines; stopping-gear, non-automatic.-A speed governor consisting of centrifugally-controlled bell-crank levers 128 determines the speed at which a rotating member 122 is to engage a spring-mounted member 115, Fig. 3, to arrest the motion of the shaft and to bring it to rest at a predetermined position, particularly as regards the position of the needle, such position corresponding to the engagement of the rotating member 122 with the stop-bracket 117 and the resistance member 115. The stop-bracket 117 is carried by a stationary disk 110 concentric with the shaft 10. Splined and slidable on the shaft 10 is a brake-disk 118 carrying the stop member 122. When at rest, the brake-disk 118 is pressed against the disk 110 by a spring 131 and is moved out of contact therewith by a slidable sleeve 151 operated by the motion of the treadle 92, Fig. 7, acting through a chain 137, a lever 135, and connexions 138, 142, and 147, the latter being pivoted at 148, and having its end 149 engaging a slot 150 in a sleeve 151. The connexion 138 is normally held against the frame 1 by a spring 139. Fixed on the shaft 10 is a spider collar 125 carrying the bell-crank levers 128. The short arms of these levers have inclined surfaces 152 engaging inclined surfaces 153 of the brake disk 118 and when the power is cut off from the shaft 10, as the speed diminishes the inclines 152 travel down the inclines 153 and so allow the spring 131 to move the brake disk 118 until the member 122 engages the resistance member 115. The member 115 is mounted in a recess 111 between springs 112, 113 which cushion said member 122 until it meets the bracket 117, after which the springs 112, 113 restore the shaft to its predetermined position. A screw stop 156 limits the movement of the lever 135 and a spring 154 allows the treadle 92 to be further depressed to engage a nut 155 to force the pulley 88 into driving contact with the belt pulley 89.
