Title: Improved Apparatus for Coupling and Uncoupling Railway Rolling Stock.
Inventor: LOWDEN JOSEPH
Filed: 1900-07-12
Granted: 1900-08-18
Abstract: 12,611. Lowden, J. July 12. Couplings, automatic; buffers.-Relates to the coupling and uncoupling of railway rolling-stock, the vehicles being provided with a central buffer which effects the coupling automatically. The buffers a, b, Figs. 1 and 2, have locking-bridles which consist of quadrant-shaped cheeks e connected by the locking-bar f and are pivoted on bolts d. The buffer a carries the coupling-hook c which, when the link r is in the position shown in Fig. 1 and the lever m is free to move, strikes the locking-bar f, raises the bridle, and couples the vehicles when in operation. To uncouple the vehicles, the lever m is depressed. Lugs w upon the back of the buffer head retain and guide the bridle cheeks e. The cheeks e, instead of being bolted together, may be formed in one piece. In the coupling shown in plan in Fig. 5, the safety hooks 1 engage with the end links of the chains 4 when the coupling-hook strikes and raises the locking-bridle of the opposing buffer, since the safety hooks and end links are carried upon sheaves 3 journalled upon the studsj<1> projecting from the bridles. For compressing the buffer springs and drawing the heads in towards the vehicle, the rocking shaft 8, Fig. 7, extends across the vehicle, and is provided with operating hand-levers 9, and cam faces which engage with the hinged cam plates 11. The rocking shaft may be operated by fluid pressure by means of the cylinder 15 and its connections.

Title: Improvements in Electrical Demand Indicators.
Filed: 1900-08-02
Granted: 1901-08-02
Abstract: 13,901. Wright, A., Dick, J. R., and Reason Manufacturing Co. Aug. 2. Current, energy, and quantity meters.-A maximum indicator consists of a strip, wire, tube, or other body of iron, copper, or other material, and an acid or other liquid capable of attacking it, the strip being moved into the liquid, or the liquid moved to the strip, by the action of the meter, the extent of such movement being subsequently shown by the length of strip dissolved or corroded, or the loss or gain of weight of the strip or the liquid. The materials are preferably such that a little time is necessary for the attack to have much effect. The invention may be applied to any kind of electric meter having a moving part, for example those described in Specifications No. 583, A.D. 1893, No. 5451, A.D. 1895, No. 3409, A.D. 1896, and No. 10,496, A.D. 1898. Fig. 5 shows a current indicator in which the liquid 3 is movable to the strip 1 by the expansion of gas in a bulb 13, caused by the heating of a surrounding resistance 6 carrying the current ; the strip 1 is carried by a removable screw plug 12. In a modification, the indicator is balanced on a pivot so that it turns as the strip loses weight. In another form, the liquid is itself heated by an immersed platinum wire, and expands in a vertical tube containing the metal strip. In another form, the pointer of a meter carries an arrangement of tubes such that in turning it decants liquid from one tube into another containing the strip. In another form, the strip is hung by a wire, which conveys the current and is heated and expanded thereby, to cause the strip to dip in the liquid contained in a stationary vessel ; or the indicating-strip may be dipped similarly by a heated strip of two metals, or by a solenoid and spring-supported core.

Patent GB-190105267-A (GB)
Title: Improvements in Range Finders.
Inventor: FORBES GEORGE
Filed: 1901-03-13
Granted: 1902-02-06
Abstract: 5267. Forbes, G. March 13. Range - finders.- Relates to the type in which the range is determined by the stereoscopic measurements o f the parallactic displacement of the images of an object, as seen in a binocular telescope with an extended optical base. Fig. 13 shows a plan of the base : Figs. 13 and 14 show the binocular. The base is made u p o f halves a connected by a rule joint a'. Each end of each half is fitted with a reflector for deflecting the rays through a right-angle, and to minimize the error due to the angular movement of one mirror with respect to the other, due, say, to unequal heating of the tube, some form of poly-faced prism is employed. The two halves a are locked together in the extended position by spring catches released by a pushbutton. Images of the distant object are projected upon discs l<1>, each of which has a fiducial line or figure marked upon it. These discs are mounted in rings connected by a sliding rod and tube m<2> to allow of the separation &c. of the two bodies h without angular displacement of the fiducial lines. One disc can be adjusted along a normal to the plane of the optic axes, and the other can be adjusted along a line in that plane by a micrometer screw n<1>, in the face of which a spiral groove is cut to operate a radial slide and index. To take a range, therefore, it is only necessary to fit the binocular to the optical base, sight the object, and adjust the micrometer until the fiducial lines are superposed upon the object, when the range can be read off on the scale.

Title: Stopping Mechanism for Lubricator Pumps.
Inventor: DEWERS HEINRICH
Filed: 1901-07-02
Granted: 1902-06-05
Abstract: 13,456. Dewers, H. July 2. Lubricators.- Means are adopted for disconnecting the piston or plunger of a pump lubricator from the actuating - mechanism shortly before it finishes the downward stroke. A worm-wheel d, operated by connecting-mechanism c, is loosely mounted on a screw e, which engages a nut to feed forward the plunger. The screw e is provided with an extension f having a left-hand thread for the engagement of a nut g. Between the nut g and the wheel d is arranged a brake disc i. By clamping the disc to the wheel d by means of the nut, the wheel is operatively connected to the screw e, the connection being broken upon unscrewing the nut. A rod k, controlled by a spring m, slides in the frame of the lubricator, and has connected to it one end of a pivoted pawl or lever n, the other end of which engages the plunger. Normally, the rod k is retained within the frame by the engagement of the pawl n with the plunger, but, near the end of the downward stroke, the pawl is released and the rod is forced out, as shown in Fig. 2, so as to engage an arm h projecting from the nut g, thereby unscrewing the nut and disconnecting the wheel d and screw e. In withdrawing the plunger, the rod k may be depressed by means of a handle o, or the arm h may be jointed so that it can be turned up out of engagement with the rod.

Title: Improvements in Means for Operating Railway Points and Signals.
Inventor: SYKES WILLIAM ROBERT
Filed: 1902-10-03
Granted: 1903-09-10
Abstract: 21,562. Sykes, W. R. Oct. 3. Semaphore and similar outdoor signals.-Handlever apparatus for operating points and signals is operated almost entirely by power, only the small movements of the catches or levers necessary for interlocking being made by hand. To one of the tails 7 of each lever 1 is pivoted a double rack 8, with which gear two spur-wheels loose on shafts 13, 14 common to the bank of levers and rotated by an electric motor 17, either continuously, or as required by the use of the foot switch 32. The spur-wheels can be rotated with their shafts by means of electromagnetic clutches, one or the other of which is energized, according to the direction in which the lever 1 is to move. The clutches are controlled by a switch comprising a contact 36 which can be connected to one or other of two contacts 38, 39 corresponding to the two clutches, by means of a sliding contact 35 carried frictionally on a rod 41 connected to the lever 1. The initial interlocking movement of the lever 1 thus operates the switch 35 and energizes the appropriate clutch. The clutch circuits include limit switches 49, 57, normally closed by springs, but opened on the completion of the stroke of the lever by engagement with the tail 7. In order to arrest the movement of the lever 1 in case of emergency, means such as the links 69, 70 and a pedal are provided for opening the switches 49, 57. In a modification, there is only one shaft, which is driven in one direction or the other as required by reversing the motor, either by means of a separate pedal switch or by a switch similar to 35. Limit switches 49, 57 are employed as before, and in addition the field-magnet circuit is controlled by, preferably, a single switch, which is closed by a cam on the rack bar when a lever has made its initial movement. In another modification, reversing clutches are employed in connection with a shaft driven in one direction. The rack bar may be replaced by an endless sprocket chain, or other motive power substituted for electricity and other modifications may be made, such as the use of more than one motor.

Granted: 1903-10-22
Abstract: 26,958. Jaakson, J. Dec. 6. Hand printing in single characters; type-writers. -The types or character project laterally from curved ribs, which are fixed to curved vertical supports 3 so that the types are arranged on a spherical surface. Instead of the curved supports, the ribs may be fixed to a hollow spherical segment of celluloid, glass, or other transparent material. On the back of each type is a corresponding mark, which may be read when the types are turned downwards. A handle 5 is provided, so that any desired type may be impressed on the paper. A guide-plate 7, Fig. 6, has a series of orifices 8, divided into groups by lines 10, the upper edges of the orifices being bevelled to guide the type to its proper position. The Provisional Specification states that the guide-plate can be connected to a heavy prism which may rotate on its axis. Each side of the prism has a width equal to the distance between two lines, so that the rotation of this prism from one stop to the next, without its leaving the paper, produces the advance of the guide-plate from line to line. The paper is held by one edge in a rod furnished at the top with a scale and at the bottom with a set of teeth. The rod slides in a groove and is retained at each line by a spring.
