Granted: 1899-06-10
Abstract: 15,476. Smith, C. July 14. Tell.-tales for checking servants. Let t e rand other collecting-boxes are so adapted as to serve as a check on the servant or agent who uses them. Within the box is fitted a tray G having a slit aa, corresponding with the slit a in the lid for the insertion of the documents. On the tray moves a slide F, which is actuated, when the lid is closed, by means of a projection B which works in a slit in the lid. On the slide is fitted a tablet CC, for writing on, and at its side, to prevent withdrawal, is a rack I in which a spring tooth on a plate H on the tray engages. The proprietor or principal writes, before closing and sealing the lid, a certain word, connected with Stock Exchange transactions, or racing, &c., as the case may be, on the tablets C, C. The agent having deposited his documents in the box, through the slits a and aa, then pushes the slide so as to close the slits and read the word through a glazed aperture C in the lid, which word he immediately telegraphs to the principal so as to denote the time when the documents were deposited.

Title: Improvements in Screw Taps and Holders therefor, also applicable to other Tools and Tool Holders.
Inventor: JUSTICE PHILIP MIDDLETON
Filed: 1898-07-26
Granted: 1899-04-08
Abstract: 16,278. Justice, P. M., [Morgan, R. L.]. July 26. Tapping; tools; toolholders. - To prevent the breakage of a tap, reamer, or similar tool while operating on ' blind ' holes, the tool is arranged to be disengaged from its holder prior to reaching the bottom of the hole. The square shank 2 of the tool is fitted in a sleeve 3, normally coupled to the holder 8 by a cottar 6 which engages a recess 5 in the sleeve, and slots 7 in the holder. The cottar has vertical play in the holder, but is pressed down by a spring pin 11. A headed pin 4 passes through the tool, and, when this is forced up by meeting the bottom of the hole, it disengages the cottar from the sleeve, and stops the tool, the holder being independently stopped. By raising the holder slightly by hand and reversely rotating it, a pin 12 in it passes from a groove 13 in the sleeve into engagement with a shoulder 14, allowing the tool to be withdrawn.

Title: Improvements in Automatic Loud and Soft Pedal Mechanism for Self Playing Musical Instruments
Inventor: KLABER AUGUSTUS DAVID
Filed: 1900-05-29
Granted: 1901-05-29
Abstract: 9858. Klaber, A. D., [Klaber, E.]. May 29. Automatic instruments.-The invention relates to means for automatically producing piano and forte effects in mechanical pianos. A is a friction drum which operates the hammers in a wellknown way. By means of a strap passing round a pulley A<2>, it drives a pulley C<1> connected by spur gearing to cams E<2> and E<3>, which alternately depress levers F, F<1>. The levers are provided with friction rollers F<2>, F<3>, and are connected by cords passing over pulleys G, G<1> with the loud and soft pedal operating-devices. The effects stated above are thus alternately and automatically produced. In order to throw the mechanism out of action, the pulleys G, G<1> are mounted on a lever K held up by a catch K<3>, on releasing which the cords slacken and the cam apparatus ceases to operate the pedal devices. In a modification, the cams are driven by worm gearing from the drum A. They may be shaped to suit circumstances.

Title: An Improved System of and Apparatus in connection with Railway Signalling.
Inventor: ROTH JOSEPH
Filed: 1900-11-13
Granted: 1901-01-12
Abstract: 20,423. Roth, J., and Helmke, W. Nov. 13. Signals on engines; stopping engines; indicators and repeaters, signal; crossing-gate signals; signalling between trains. - For signalling in foggy weather, apparatus on the line is employed to actuate apparatus on the engine. Fig. 2 shows one form of the line apparatus. The actuating-bar D is normally held out of action by weights K connected with it by cords G. When the cord L is pulled, the bar D is drawn forwards to the operating position. In a modification, weighted levers are arranged to set the bar in its operating position, and the cord L is pulled to withdraw it. The cord L may be attached to the signal-operating lever or may be separately actuated. Fig. 20 shows the apparatus on the engine. The lever a can be set in the operative or inoperative position by engaging the notch or the notch k in the handle h with a stud on the pivoted bar f. If the lever is in the operative position, the wheel c strikes the bar D, with the result that the bar f is moved. The bar f may be arranged to strike on a bell, or a cord p attached to it may actuate a mechanical or electric bell or other audible signal, such as the whistle of the engine. The cord p may also be arranged to operate the regulator and shut off steam. One or more fixed bars may be employed in conjunction with the bar D. If, for instance, there are two, one on each side of it, two signals will be sounded when the line is clear and three when it is blocked. The gate of a level crossing may be arranged to pull the cord L, operating a bar D or an ordinary semaphore. Fig. 13 shows apparatus by which a train standing in a station operates a cord L. The flange of the wheeLY depresses the treadle V, against the action of the spring t, operating the lever W, to the outer end of which the cord L is attached.
