Title: Improvements relating to the Fixation of Pigments or Metallic Powders in Printing on Textile Fabrics or similar Surfaces.
Filed: 1897-03-09
Granted: 1898-01-08
Abstract: 6112. Kay, W. E., and Thornliebank Co. March 9. Bronzing and the like.-In fixing metallic powders, such as gold, bronze, or aluminium, upon calicoes or other textile fabrics, or similar surfaces, the powder is prepared as a colour with gelatine and is printed on the fabric, and the printed material is then treated with a 1 to 2 per cent. solution of formic aldehyde by means of a padding-mangle, a separate printing-roller, or as a spray, or in other suitable ways, after which the material is dried. Other substances which are rendered insoluble by formic aldehyde, such as glue, albumen, casein preparations, or the like, may be substituted for gelatine. The fixing process may be combined with the mercerizing processes for producing crÚpon effects, or a silk lustre, on the material.

Inventor: BEAUCHAMP FRANCIS
Filed: 1897-03-31
Granted: 1898-03-05
Abstract: 8286. Beauchamp, F., and Colman, J. C. March 31. Driving-mechanism. - Figs. 3 and 5 show the application of the invention to a bicycle. A pinion A, mounted on a bracket B on the frame C, drives a face or other wheel I carried by the rear-wheel hub. A rod L connects the crank-pin J on the wheel A to a sleeve K<7> which slides on the treadle - lever K. The latter is pivoted to the frame at K', and has pivoted to it at K<2> a rod K<3> carrying a pedal K<4> and connected by a rod K<5> to the sleeve K<7>, as shown. The treadle leverage can be varied by placing the pedal axle in either of two sockets M, M<1> formed on the lever K. Moving the pedal from one socket to the other also causes the sleeve K<7> to slide on the treadle-lever, thus further altering the treadle leverage. The pedal can be secured in either position by a spring-actuated pin M', shown separately in Fig. 5, which enters holes M<5> formed in the sockets M, M<1>. It is released by pressing outwards a projection M<6> formed on the pin M<2>. Similar gearing may be placed on the other side of the bicycle, or a second treadle-lever may be connected to the lever K by a rocking lever or other mechanism which causes one lever to rise as the other falls. Fig. 6 shows a form suitable for a tandem tricycle. A second rod L<x> connects the wheel A to a rearwardly-extending lever K<x>. In this form, the points of attachment of the rods L and L<x> to the levers K, K<x> do not change when the position of the pedals is altered. A starting- device for moving the levers over the dead points may be provided. This consists of a lever P pivoted to the frame and having hinged to it a pawl Q which engages the teeth of the wheel A when pressure is applied to the end P' of the lever. Normally, the lever is turned up out of reach of the wheel A.

Title: Improvements in Method of and Means for Operating Alternating Current Motors.
Filed: 1897-08-03
Granted: 1897-09-11
Abstract: 18,095. British Thomson-Houston Co. [Steinmetz, C. P.]. Aug. 3. Motors, controlling.-For the purpose of starting and regulating alternating-current motors, especially those of the induction type, two or more such motors are employed in combination ; the primary or inducing winding of the first is connected with the alternating-current supply, while the primary of each of the succeeding motors is connected with the secondary or induced winding of that preceding it ; the secondary of the last motor is closed upon itself and means are provided for varying the resistance in circuit with it. Fig. 1 shows an arrangement comprising two three-phase motors M, M'. The primary P of the first motor M is fed with alternating currents through a transformer T, while its secondary A supplies the primary P' of the second motor M<1>, the secondary of which A' is closed upon itself either directly or through resistances R, R', R<2>. The motors are started by means of a controller C, consisting of a cylinder furnished with three separate contacts S, S', S<2> and three connected contacts s, s<1>, s<2>, against which bear brushes a, b, c, d, e, f, g, h, i, connected to the secondary A<1> and the resistances R, R<1>, R<2>, as shown. In position 1 of the controller the current is interrupted ; in position 2 the resistances are included in the branches of the secondary winding A' ; in position 3 a portion of each resistance is cut out ; finally, in position 4 the secondary winding A' is entirely short-circuited and the motors run at full speed. For the purpose of further varying the speed and power of the motors, means are provided for varying the connections of motors from tandem to parallel. Such an arrangement is shown in Fig. 2, the two motors M, M<1> having their primary windings P, P<1> connected to brushes bearing on a controller cylinder C, while the secondary windings A and A' are connected together by conductors 1, 2, and 3 having contact rings r, r<1>, and r<2>. The remaining brushes are connected with the transformer T, the resistances R, R', and R<2>, and the contact-rings r, r', and r<2>, in the manner shown. The contacts on the controller cylinder are so arranged that on rotation the following relations are established :-In position 1 the controller is idle ; in position 2 the two motors are placed in tandem with the resistance in circuit ; in position 3 a portion of the resistance is thrown out ; in position 4 the resistance is entirely short-circuited ; in position 5 the motors are connected in parallel with the transformer T ; and, finally, in positions 6 and 7 the resistance is gradually cut out and the motors attain their highest speed. The system may be applied to a larger number of motors, in which case greater variations of speed and torque may be obtained. In applying the invention to a railway car, the two motors are geared to the two axles of the truck.

Title: Line Closing Attachment for Linotype Machines.
Inventor: MUEHLEISEN CARL
Filed: 1898-07-26
Granted: 1899-07-01
Abstract: 16,255. Muehleisen, C. July 26. Lionotype machines.-Relates to means for closing the lines in linotype machines such as described in Specification No. 14,582, A.D. 1890. The sliding frame B of the elevator is attached to the main frame A. The left vice jaw L is of the usual form, and the right vice jaw R is adapted to slide to and from the left jaw. A ratchet bar 1 is connected to the jaw R, and has oppositelyinclined teeth 2 and 3 on its upper and lower edge with which spring-controlled pawls 4 and 5 co-operate. The pawls engage pins 8 connected to a link 7 which is coupled to a lever 11. By raising and lowering the link 7, the pawls can be alternately engaged with the ratchet bar. The jaw R is constantly urged towards the left by a spring 13 connected to one arm 14 of a rocker, the other arm 16 of which is connected by a link 17 to a lever 18, the lower arm of which has a slot engaging a pin on the ratchet bar 1. The link 17 passes through an eye on the arm 16, and is encircled by a spring 23, thus forming a flexible connecting-member. The lower end of the spring 13 is connected to a lever 25 which is retained in its lowest position by a stop 26. When the lever is thrown up, so as to occupy the position shown by dotted lines in Fig. 1, the jaw R remains in its normal position. The frame B carries an arm 27 having an adjustable screw 28 which comes in contact with the lever 11 just before the line reaches the casting or lowest position. After the casting the elevator frame rises, and a cam 29 engages a roller 30 on the arm 14 and carries the jaw R back to its normal position. In operation, when lines short of the column measure are being assembled, the lineclosing device is thrown into action by means of the lever 25. When the line is assembled, it is carried over to the elevator B and lowered in position between the jaws L, R. During the last portion of the downward movement the screw 28 engages the lever 11 and throws the pawls 4 out of action and the pawls 5 into action. As soon as the pawls 4 release the bar 1, the jaw R is drawn to the left by means of the main spring. The justifying- wedges are then driven in. The mould is then moved against the matrices, and the casting takes place, the right jaw serving to close the line. The elevator now rises, and the pawls 4 come into action, preventing the backward movement of the jaw R. The jaw is afterwards moved to its normal position by means of the cam 29. The device may be connected to, and operated by, other parts of the machine.

Pottery.-Fig. 1 shows a plaster-of-Paris mould constructed of two halves A, B formed with interlocking annular rings and recesses, and Fig. 2 shows a profile tool I for shaping the interior and mouth of a tea-pot or like article C in one operation. A metal ring H is slipped round the mould sections to prevent distortion under horizontal pressure, and the lower section is inserted in the usual rotary jigger head. The halves of the article may be moulded and shaped separately in the mould sections shown in Fig. 3, and are afterwards brought together and joined. A recess G is provided in one of the sections to receive surplus clay pinched off at the junction of the parts. The upper half of the article is first moulded by inverting the mould section A, placing it in the jiggerhead D, and bringing a profile tool carried by a lever to bear on the clay placed in the section. The section A is then removed and replaced by the section B, and a second profile tool, carried by a lever jolly, set at an angle with the first lever is brought into action to shape the bottom of the article. A vertical jolly is described in which the profile tool is carried by a vertical sliding bar or shaft which is set out of the centre line of the mould. The tool is brought into action by moving the shaft downwards and rotating it a portion of a turn. The plaster moulds are cast in moulds built up of metal rings, so that the plaster can only expand in a vertical direction.
