Patent GB-190101527-A (GB)
Title: Improved Automatic Electrical Attachment for Clocks for Ringing Bells and other Purposes
Inventor: CLAPHAM WILLIAM
Filed: 1901-01-23
Granted: 1902-02-20
Abstract: 1527. Clapham, W., Clapham, A., and Clapham, A. Jan. 23. Alarms.-A cam disc X, which is screwed to a wheel B revolving once in twenty four hours, releases for a time a train of levers D, E, which hold a detent F up to a pin P on the last wheel of the alarm train, and a cam H on the minute arbor allows the detent to drop. As the train runs, a rim K on the slowest wheel K<1> completes the circuit of an electric bell by pressing a spring terminal M<1> against a fellow terminal M'. Presently a finger R', which a cam L acting on another finger R<3> drops against every tooth of the wheel, finds a deep interdental space S<2>, and simultaneously a gap in the rim breaks the circuit, while a third finger R' stops the train. Finally, the detent F is reset, and lifts the three fingers by raising a fourth R'. The disc X may be replaced by another cut to make the action occur at some other hour of the day, and the cam on the minute-arbor is set by hand to determine the minute of alarm. If the alarm is to be sounded at a different hour each day of the week, the required discs are all put on the hub of the twenty-four hour wheel, the daily change being effected as follows :-The twentyfour hour wheel B is mounted friction-tight upon the hub C of a notched disc behind it, and an incomplete rim upon it masks the disc so that the two turn together except when the gap in the mask allows a pawl T to hold the notched wheel for a time. The hub of the wheel is stepped, and being thus turned relatively to a pin on the hub of the disc, a spring between them shifts the latter a step day by day, so as to bring a different cam disc X to the releasing-lever D of the train.

Title: Improvements relating to the Correction or Variation of Spherical Aberrations in Dioptric Lens Systems.
Inventor: GOERZ CARL PAUL
Filed: 1901-04-10
Granted: 1901-07-20
Abstract: 7417. Goerz, C. P. April 10. Lenses.-R elates s to a mathematically - deduced method of correcting or reducing the longitudinal aberration in lens systems. In a lens such as that shown in Fig. 1, the central axial ray C and the marginal parallel ray R are brought to a common focus at P, but rays passing through the intermediate zones, such as M, intersect the axis in different points, such as P<1>, within the point P, i.e., the intermediate zones are under-corrected. This zone error is reduced, as shown in Fig. 2, by introducing a second cement surface S of great curvature between two lenses of but slightly different refractive power. This second surface may also be made in the diverging component of the combination. Fig. 4 represents the application of the principle of the correction to the object glass of a telescope. The elements of construction are as follows :- As an example, the principle is also shown applied to a lens of the type described in Specification No. 23,378, A.D. 1892, [Abridgment Class Photography]. In the case of a doublet, the mean zone of one of the components may be undercorrected, while the other is correspondingly overcorrected. The principle may be applied to lenses generally, such as those for telescopic, microscopic, and photographic purposes.

Abstract: 10,784. Anderson, J. C. May 1 . Liquid meters.-Locking means are provided for securing the registering mechanism of a liquid meter against fraudulent manipulation. Figs. 1 and 3 show the invention as applied to a meter of the piston type. The piston 2 has a circular race 4. which is engaged by a stud 5 screwed into the casing 6 for the purpose of limiting the movement of the piston and preventing its withdrawal from the cylinder. The first gear-wheel 7 of the registering mechanism is mounted on a spindle carrying a toothed wheel 10 engaged by a pin 11 on the piston. The mechanism is enclosed by a glazed cap 12 provided with a hinged protecting cover 13. Dowel pins 15, between the cap and casing, prevent the cap from being twisted should the screw 16 be removed. A latch ur keeper 17 secured to the casing by the stud 5 is provided with a stepped arm 19, which projects over a pocket in the casing. A boss on the cap enters this pocket, and is provided with a gate to clear the arm 19. An index dial 22 is located in a recess in the cap and has a number of radial slots, one of which is engaged by a feather on a spindle 25. On a square part of this spindle is mounted a disc or tumbler 27 carrying a ring 29 for engaging internal projections on other tumblers 30, 33 mounted on the tumbler 27. The tumblers are gated to pass the arm 19, and, when the gates are out of register, they take under the steps on this arm to secure the cap. The tumblers are separated by gated washers and a cap 38 secured to the boss which encloses the tumblers. By rotating the spindle, so as to bring the disc into a position predetermined by the combination, the gates in the tumblers are brought into register with the steps of the arm, so that the cap can be removed. The head of the spindle is provided with a V-shaped cut for the insertion of a turning tool. The downward pressure exerted in turning the spindle frees the tumblers from engagement with the steps on the arm, so that the combination cannot be determined by the sense of touch.
