Title: An Electrical Motor.
Inventor: MESSIER LOUIS PHILIPPE JEAN AN
Filed: 1908-01-31
Granted: 1908-11-26
Abstract: 2222. Messier, L. P. J. A. H. Jan. 31. Reciprocating-type.-An electro-magnetic motor, particularly adapted for percussive hand-tools &c., consists of a single coil, the core of which oscillates between two stops when an alternating or undulating current passes through the coil. Generators modified for supplying a suitable undulating current are described. In the motor shown in Fig. 1, the core 2 has non-magnetic ends 3, 3<1>, and is thrown into an extreme position when the coil 1 is de-energized by a spring contained in a detachable head 4. The other end of the core holds the percussive tool. The coil is supplied with an alternating or preferably undulating current, or a direct current may be superimposed upon an alternating current. The current may be obtained from one of the ordinary brushes of a continuous-current two-pole dynamo and from a brush caused to rotate upon the commutator in the same direction as the armature. To obtain the undulating current, a dynamo with two commutators, one having twice as many segments as the other, may be used. A suitable current is derived from a pair of brushes, one upon each commutator, angularly displaced by an angle slightly greater than the pole pitch. In another method of obtaining an undulating current, a bipolar alternator has one end of the armature connected with a copper ring A, Fig. 9, mounted upon the armature axis and bearing a stationary brush C connected with the line L. The other end of the armature is connected to a semicircular copper ring D mounted upon the axis of the armature, the other half of the ring being insulated. Two stationary brushes G, H, at 180 degrees to each other and perpendicular to the plane containing the two poles, rub upon this split slip-ring. The circuits are arranged as shown in Fig. 9, one of the groups of coils, say B, B<1>, B<2>, receiving the upper halves of the alternating wave, and the other group receiving the lower halves. The positive and negative waves may be separated by an electric valve.

Granted: 1910-05-02
Abstract: 2376. Angus, A. R. Feb. 1. Axle-bearing guiding arrangements; axles; axle-trucks and bogies. -The bearings of divided axles of the kind described in Specifications 22,776/05 and 8033/06 are permitted slight lateral play in the axle-boxes for radial action. To provide further restraining-means against change of gauge of the wheels and departure from alinement of the semi-axles owing to wear of the collars and keeps blocks and bearings, the semiaxles are socketed together and " axial liners " are mounted on the truck framing to embrace the wheel rims. Fig. 1 shows the invention applied to a bogie truck, but it may also be applied to other trucks. Bearings 22, 23 are provided upon both sides of the wheels, and are connected by a framework 24, 25, which carries the upper frame 30. Both upper and lower bearing-blocks 31, 36 are provided so as to prevent relative movement of the axles and the frame 24, 25, but lateral play of these blocks is allowed for radial action. The inner bearings 23 are connected by a casing 43 containing upper and lower keeps blocks 46, 47 which engage collars 51 on the semi-axles. The end of one semi-axle enters a tapering socket 52 formed on the other. Passages 41, 58, 60, 61 are formed for lubrication. Departure from alinement of the semi-axles in the vertical plane, on account of wearing of the bearings 31, is restrained first by the keeps blocks 46, which are adapted, when such wear has taken place, to have a bearing upon the casing 43, and later by the " axial liners " 63, Fig. 1, secured to the frame 25, and with which the wheel treads may contact. Further restraint is also imposed at this stage by the socketed portions of the semi-axles. The " axial liners " 63 and the socketing of the semi-axles, also serve to check change of the gauge of the wheels when the collars 51 become worn.

[Cognate Application, 14,656/10.] Aerial machines without aerostats; planes, arrangement of; framework.-The framework of an aerial machine of the monoplane or multiplane type is built up of hoops or sections of hoops arranged in angular relationship. The fusilage is composed of five pairs of hoops 1, 2, 3, 4, 5, as shown in plan in Fig. 2 and in elevation in Fig. 1. The transverse planecarrying structures may also consist of five pairs of hoops, although spars may be used instead. When hoops are employed, they are arranged as shown in Fig. 3, so as to form a lateral dihedral angle. The framework is braced by rods 28 and by struts 31 which carry the elevators, and wires 44 may also be used. In order to render the framework adjustable and disconnectible, the parts are connected together by clips, Figs. 7 and 8. To connect two hoops, collars 45 are clipped to the hoops and are then connected together by a screwed boss 46. By means of a ring 47 and socket 48 a straight strut may be connected to the hoops; or the ring 47 may carry pivots 49 upon which sockets or screwed shanks for the straight struts are threaded. The hoops may also be aggregated as shown in Fig. 6, each pair being connected at 24, 25, 26, 27. The planes may be of the form described in Specification 27,988/09. The rear planes 37, 38 are arranged at a higher level and at a lesser angle of incidence as compared with the front planes 39, 40. The lower planes 38, 40 are disposed in advance of the upper planes and are adjustably clipped to the hoops. Propelling.-Two independent motors 35 are employed to drive the propellers 36, which may be clutched together. Steering.-Two rudders at the front and rear may be used. The outside pairs of hoops 15 are pivoted about inclined axes 41 in order that the side wings may be swung forwards or rearwards. The wires for operating these wings may be connected to the steering-member which controls the rudders so that operation of the rudders and wings is effected simultaneously, or so that the wings may be operated independently either individually or collectively. The wings may be locked in any desired position.

Granted: 1910-07-21
Abstract: 1802. Hilgers, W. Jan. 24. Shearing; rolling. - In rolling-mill shears of the rotary type, the shear levers may be actuated independently of the rotation of the wheel on which they are mounted so that cutting may take place when the wheel is stationary. One or more wheels a' are mounted on a hollow shaft e, each carrying one or more pivoted cutters d, the rear ends of which pass through slots in the shaft. The cutters are oscillated by pistons o, n, which are reciprocated by a rod and crank m operated either by a pulley k<1> when the wheel is stationary, or by bevel-gear l clutched by a hand-lever to the main driving-shaft i, which rotates the hollow shaft e by gearing g, h. In order to interrupt the cutting without interfering with the drive, the piston n is notched at z, and is carried by a sleeve s', which may be rotated on the piston-rod s by a handle p, which may be operated manually or automatically. The shears may operate in either direction of rotation to act on work either entering or issuing from a pass, or when the bar is stationary; or a moving bar can be cut while the wheel is stationary or merely dragged round by the bar. The shears may operate in any angular position and thus may be used with three-high or four-high rolls, the bars being bent as they issue from the rolls so as to become tangential to the wheel. The apparatus can be used for trimming or cutting into lengths.
