Granted: 1909-02-11
Abstract: 11,746. Harrison, J. A., [Harrison, E.]. May 30. Cameras.-In mechanism for swing and like adjustments of the front, applicable also for the back, the slotted arm supporting the front, is itself carried by one or more arms pivoted to the base of the camera, and can be folded against and locked to one of such arms so as to swing with them. A pin-and-slot interlocking arrangement is provided for the arms pivoted to the baseboard for certain positions of the camera, and a tongue or projection piece is adapted between the front and its supporting arm to maintain it in alinement, but adapted to be put out of operation as required. The front P, Fig. 5, is clamped to the slotted arm F, which itself is pivoted at N to the arm D and clamped at L to the arm E. The arms D, E are pivoted at M, T respectively to the support A on the baseboard. The arm F can be folded and locked alongside the arm D by the catch I and then turns with it, the adjustment of the front being still possible by the motion of the clamping-nut L in the arm E. The arms D, E are interlocked by a pin-and-hole connexion. A pin on the lever J projects into one of a series of holes in the arm D corresponding to different relative positions of the front and baseboard. The arms are kept locked by the spring K, and are unlocked by turning the lever J which is then raised by the cam knobs s, s<1> to withdraw the pin. An equivalent pin-and-bolt interlocking arrangement may alternatively be mounted in connexion with an adjacent part of the camera. A spring tongue G, Fig. 3, is attached to the clamping-nut V and engages grooves W on the front P. To tilt the front the nut V is unclamped when the tongue G is forced away by the spring plate H fitted to it. In another modification, the ends of the spring tongue may be passed round the sides of the arm, or placed so as to recede into the side of the front, under pressure from the plate H, as in Fig. 7, or again the spring plates G, H may be attached to the spindle 0, Fig. 9, which slides longitudinally in the clamping-nut and screw V.

Title: Improvements in Automatic Belt Tensioning Mechanism.
Inventor: CHAMEROY EMILE
IPC: F16H7/14
Filed: 1909-07-16
Granted: 1910-06-09
Abstract: 16,657. Chameroy, E. July 16. Tension arrangements.-Relates to automatic belttensioning mechanism of the kind in which the driving-pulley f is carried by arms c pivoted on a power shaft a and is geared to the latter so as to be rotated in the opposite direction thereto, the action of the gear and the drag of the belt r causing the pulley to tend to travel round the power shaft, thereby tensioning the belt. Alternatively the arrangement is applicable to the driven pulley. The invention consists in prolonging one of the arms c carrying the pulley f, and pivotally connecting the end l thereof to a spring-pressed rod m which provides an initial pressure to start the tensioning action. Adjustable nuts q on a threaded portion of the rod m regulate the tension of the spring o which bears against a fixed abutment p. The belt may be put out of action by means of a pivoted lever s having a slotted engagement with a pin n on the rod m. To prevent excessive tensioning of the belt, a compensating adjustable spring may be arranged on the slidable rod m or at any other part of the apparatus to come into action to counteract the tensioning-device when the movement of the latter is excessive. As shown in Fig. 4, a compensating-spring x may be arranged on the rod m on the opposite side of the abutment p to limit the movement of the rod by bearing against adjustable nuts u, v on the threaded end thereof. To protect the threaded end, the nut u is provided with a tubular extension z engaging the end coils of the spring x.

Filed: 1909-07-22
Granted: 1909-12-09
Abstract: 17,130. Gwozdz, B. July 22. Kinematograph apparatus. -The amount of light thrown on the film is automatically regulated by means of a selenium cell &c., in accordance with the varying permeability of the film. In the arrangement shown in Fig. 1, a concave mirror 8 throws upon the selenium cell 7 a reduced image of the picture on the projection screen 6, and thus any variation from the normal brightness of the picture produces a corresponding variation in the resistance of a circuit 9 provided with a polarized electro-magnet 10, which controls a light-regulating device in the form of a two-part ruled screen arranged between the condenser 2 and the film 5. This device consists of a fixed part 11 and a laterallymovable part 13, which is secured at one side to a spring 15, and at the other side to a two-armed lever 17 carrying an armature 19. In a modification, the source of light is regulated and the regulating-screen dispensed with, the selenium cell being connected to a demagnetizing-coil applied to the magnet of the generator which supplies current to the source of light. In the arrangement shown in Fig. 4, the action of the selenium cell 7 is assisted by means of a second selenium cell b, on which the light is reflected by a transparent mirror c, and which is connected to a second winding d on the polarized electro-magnet 10. The cell b is affected as soon as the cell 7 commences to regulate the screen 11, 12. The two selenium cells may act upon the generator supplying the source of light, instead of upon a regulating- screen, and the second cell b may be arranged behind the source of light, the mirror c being then dispensed with. In the modification shown in Fig. 6, the effect of the selenium cell 7 is increased without the use of a second selenium cell. The light, after passing through the objective 4, is partially reflected by a prism e, and is thrown by a mirror f and a condensing-lens g through an extension 11<a>, 12<a> of the screen 11, 12 on to the cell 7. The ruling of the screen is so arranged that the part 11<a>, 12<a> has a reverse effect to that of the part 11, 12. The two parts may be arranged and operated separately, and the part 11, 12 is dispensed with when the cell 7 is arranged to regulate the source of light. Modified devices for electrically operating the light - regulating screen are described.
