Abstract: 4146. Cassel, E. F. Feb. 21. Exposures, determining. - Exposures in photographic cameras are controlled by setting the driving-spring of the shutter, and the adjustable diaphragm, by means of two or more relativelyadjustable scales indicating certain conditions which affect the intensity of the action of the light upon the plate. In the form shown in Fig. 1, two scales i, n are mounted on the camera concentric with the lens. On these scales are marked the different conditions of the view and of the light. The pointer d which indicates the adjustment of an iris diaphragm, is set to the kind of view to be photographed on the scale i. The pointer m which controls the tension of the shutter spring is set to the state of the light as indicated on scale n. Modifications are described in which the scales are concentric but of different diameters, the final scale showing the sum of the displacements of the other scale, which sum indicates the displacement of the diaphragm index.

Title: Improvements in Mechanism for Operating Stringed Musical Instruments.
Inventor: SINCLAIR MATTHEW
Filed: 1903-02-24
Granted: 1903-07-09
Abstract: 4336. Sinclair, M., and Smith, H. M. Feb. 24. Automatic instruments.-For playing a mandolin or like instrument mechanically, the instrument is carried in a frame in the manner shown, and the strings are stopped by buttons 7, which are operated by tracker mechanism acted on by pneumatics 3 in the ordinary way. Two separate pneumatic actions are used for operating the plectra 56, which, in the case of a mandolin, are four in number, one for each pair of strings. The plectra are carried on rods 29, which pass through a guide-rail 34 in which are mounted adjustable pins 37 engaging with notches in the rods. When a rod is pulled down by a pneumatic 25, the pin causes the plectrum which it carries to be moved towards the strings. One of the members 26 of a second set of pneumatics then comes into action, and, by pulling on a rod 40, acts upon a lever 41 connected to the rod 29, which is thus rotated, causing the plectrum to strike the strings. This rotation may take place as often and as rapidly as may be required, so as to give the usual tremolo or trill effect. The plectra may be pivoted on their rods and acted on by springs so as to render them flexible, and means are also described for automatically pressing them against the strings so as to produce a louder note.

Title: Improvements in and connected with Hoppered and Tipping Railway Wagons for Carrying Minerals and the like.
Filed: 1903-05-25
Granted: 1904-05-05
Abstract: 11,873. Metropolitan Amalgamated Railway Carriage and Wagon Co., and Morgran, A. E. May 25. Wagons.-The hoppered wagons and tip-wagons composing a train are operated to discharge simultaneously their contents, such as ores, coal, or the like, by means actuated by compressed air or a vacuum or steam carried along the train from the locomotive or a separate wagon. According to the Provisional Specification, the actuating-means may be electrical. In the form shown in Figs. 4 and 6, the small pneumatic motor 16 carried on one end of the hoppered wagon 1 communicates with the train-pipes 17, 50, which supply the compressed air, so that the vertical shaft 18 can be rotated in either direction to open or close the sliding doors 7, 8, 9 by means of the worm gearing 19, bevel gearing 31, 35, and worm gearing 42. Clutches can be actuated by means of hand-levers 46 to throw the doors along either side of the wagon into or out of connection with the motor, and the motor is provided with cocks which allow it to be placed out of communication with the train-pipes. In modifications, the motor may be replaced by a separate pneumatic cylinder for each door, and, as shown in Figs. 14 and 15, the doors 66, 67 and the cylinders 74, 75 may be pivoted. The door 66 is secured to frames 94 connected by toggle-levers 90, 79 to a shaft 80, which is rotated by the motion of the piston-rod of the cylinder 74 to open or close the doors. The alternative mechanism shown in Fig. 18 for operating the doors 66 comprises toggle-levers 106, 107 connected by links 103 to toggle-levers 104, 102, which are operated by the rotation of the shaft 80, the levers 102 having slots 111 to permit the motion. In the tip-wagon shown in Fig. 22, the body 113 turns on the pivot 114, and is connected by links 120 to a slotted arm 119 carried by the piston-rod 117 of a pneumatic cylinder 116. A catch 122 on the body normally engages a lever 121 pivoted on the underframing and connected to the piston-rod 126 of an auxiliary cylinder 127. Compressed air to tip the wagon first enters the auxiliary cylinder, whereby the catch 122 is released, and the piston of the auxiliary cylinder then uncovers a port into the cylinder 116. When the wagon is being tipped, the pivoted door 130 is automatically released from the catches 133 by the levers and links 136, 137, 139, of which the lever 139 has a slot engaged on a pin fixed to the underframing. In a modification, the door is pivoted at the bottom and is connected to levers pivoted to the underframing so as to open and close the door when the body is being tilted.

Surfacing and polishing.- Relates to boot and shoe finishing machines, applicable also to machines for grinding and polishing metal and other surfaces, and consists in reducing the number of finishing-wheels to preferably two, one wheel being used for roughing and bottom scouring and the other for polishing purposes. Each wheel is made in two parts h, i, the former of which is fast, and the latter loose on the shaft of the machine. They can be secured together by turning the part i so that arms k, on each of the parts, engage recesses formed across the face of the other part. The adjoining parallel faces of the arms k form jaws which can be opened out or closed by means of a cam l and roller m on turning the stud carrying this roller with a key. When the jaws are opened, pieces of felt and glass-paper or emerycloth are successively passed around the wheel and their edges forced over pins o in the face of the jaws, so that, when the latter are closed, the emery &c. is stretched and held taut. Thin metal strips g cover the gaps formed at the back of the arms k when the jaws are closed. Each of these wheels may be fitted with a pivoted arm c, Fig. 2, carrying adjustable guides f against which the boot rests when scouring and smoothing the edges of the sole. The guides f or the arm c are swung out of the way when the wheel is required for bottom scouring. The machine is driven by a single treadle, but the invention is also applicable to power-driven machines.

Title: Improvements in and relating to Electric Oil and like Switches.
Filed: 1905-01-10
Granted: 1905-12-07
Abstract: 522. British Thomson-Houston Co., [General Electric Co.]. Jan. 10. Switches.-In oil-break and like switches, the contact-enclosing vessel is constructed so as to confine the pressure produced by the arc and utilize the subsequent rush to extinguish it. In the form shown in Fig. 1, the oil vessel 1, mounted upon the terminal 8, contains a fixed contact 2 which receives the lower end of the movable contact-rod 4, passing through a slightly larger hole 13 in a partition 12 located near the bottom of the vessel. When the contacts are separated, the plate 12 confines the pressure until the rod 4 is raised clear of the hole, through which a rush of oil then passes. In the absence of oil, the air will be subjected to a similar action. In the complete switch, pairs of rods 4 are yoked together to form bridgepieces, and are placed together with corresponding pairs of oil pots in a fire-proof chamber. Oil pots composed of non-conducting material, such as wood, may be used when it is desired to prevent the formation of arcs between the pots and the drawnout contacts. In this case they are made of staves bound with twine or the like and lined with fireproof material. In another modification, Fig. 4, an inner insulating-lined airtight vessel 22 is placed in the outer vessel 1, with which it communicates through the yielding socket 2 of the fixed contact, and also through small holes 24 which prevent permanent inequalities cf pressure. The outer vessel is vented by openings 25. The pressure produced in the inner vessel when the contacts are separated causes the oil to rush through the socket 2 and extinguish the arc. Any power-actuated mechanism such as that described in Specification No. 8208,A.D. 1900, may be used to operate the switches.
