Title: Improvements connected with High Tension Magneto Ignition Apparatus for Internal Combustion Engines
Filed: 1908-04-07
Granted: 1908-09-24
Abstract: 7747. Chambers Motors, Ltd., and Patton, A. M. April 7. Gas and like engines, igniting in. Magneto - electric machines are provided with a driving - connexion between the magneto and its driving-shaft, such that the magneto moves rapidly at the moment of firing even though the driving-shaft be turned slowly. As shown in Figs. 1, 2, and 3, the device consists of a sleeve d on the armature shaft e, which carries a pawl f capable of engaging, under the action of a spring g, with slots b in a fixed ratchet a. When the engine is slowly turned with the pawls engaged, the arms i on the driving- shaft h move away from stops m on the sleeve d and strain the springs k until one of the arms i strikes a balance weight n, frees the pawl, and so allows the springs k to drive the magneto rapidly. When the engine is running at normal speed, the weights n fly out against the action of the spring g by centrifugal action and keep the pawls disengaged. To facilitate over-running, the face of the pawl should be cut away slightly as indicated in Fig. 2. The pawl may be arranged externally as shown in Figs. 5 and 7, a spring k being coiled round the sleeve d ; in this modification, when the driving-shaft turns slowly, the pawl is engaged and the spring k is strained until the bevelled face of the arm i engages the incline p on the pawl g so as to free the pawl and allow the spring k to move the armature rapidly. When the shaft h is rotating rapidly, the arm i engages the pawl so frequently that the pawl cannot engage and the magneto is driven direct.

Granted: 1909-07-26
Abstract: 9026. Frank, S. April 25. Forging; squirting. -In ingot piercing and squirting apparatus, the piercing and squirting tools are readily removable, while the ingot holder is moved during the operations with respect to the press. Fig. 2 is an horizontal cross-section of the press, showing the ingot holder o, hydraulic ram d, and hydraulic cylinders f, v for returning the ram and holding the stop w respectively, the cylinders for moving the ingot holder not being shown. Fig. 5 shows the ram and holder prepared for piercing an ingot u. A punch holder i is attached to the ram head by a spherical joint g, and the punch m, shown enlarged in Fig. 8, is similarly attached to the punch-holder, by which arrangements the punch is more easily centred. The punch is first pressed into the ingot up to the position shown in Fig. 6, during which operation the metal flows backwards in the usual way. The ingot holder is next moved to the left, when the plug 1 is first ejected, and then, as the ingot holder passes over the punch holder, the latter forces out the punched ingot. Fig. 13 shows a modified arrangement in which a recess is provided in the stop w to receive the plug 1, which is subsequently ejected by means of a cam 21 and plunger 20. After piercing, the apparatus is prepared for squirting by replacing the punch holder, punch, and stop by the plunger 15, Fig 9, former 9, and die 2 respectively, although in practice two separate machines may be employed. The angle of the face 16 of the die is from nine to eleven degrees. The plunger 15 is constructed with a central rod 13 on which are a number of steel sleeves 12 with a covering-tube. With this arrangement, only the central rod would yield if a breakage occurred. As in the piercing- apparatus, centring is obtained by a spherical joint g, while the former 9, which is slightly taper, is loose, and remains in the tube after squirting. To withdraw the former, a rod 5, Fig. 11, is inserted and struck by a hammer. The same rod may 'be used, by the employment of a sleeve 7, to loosen the tube from the die.
