Granted: 1907-04-20
Abstract: 9345. Johnson, J. Y., [Willcox & Gibbs Sewing Machine Co.]. April 20. Overedgestitching machines.- Relates to improvements in the machine described in Specification No. 6557, A.D. 1892, in which all the moving parts are mounted on the lid of a box frame. The needle-bar and take-up levers for both threads are pivoted on one shaft and are actuated through pitmans from eccentrics on the main shaft. The looper is pivoted near its middle point on a swing- ing link 56, Fig. 11, and its lower end is actuated by a crank. Feed.-The feed comprises upper and lower feed dogs 70, 71, Fig 12, which are adjustably attached to slides 78,79. These slides are moved longitudinally by a pivoted frame 84 which is actuated by an eccentric rod 87 adjustably attached to it in the usual manner. The dogs are closed and opened, alternately, to grip and free the work, by cams on the shaft 22. The lower dog 71 is also provided with auxiliary feeding-surfaces 200, 201. Presser-feet ; thread-cutters; work-supports; guiding materials.-The presser-foot is attached to an arm 63, Fig. 9, pivoted on the machine cover. It may be raised by a hand-lever which engages a roller 65 on a second arm 66. If the machine is started with the presser up, a cam on the main shaft engages the hand-lever to free the presser. The presser is pressed towards the work by a spring 114 confined between a lug 115 and a cam-actuated lever, which is lifted to free the work during the feeding-movement. The feed-dog 70 passes between the parts 103 and 105, the latter of which is provided with teeth 205 which co-operate with like teeth 202, Fig. 11, on the work-plate to hold the work during the formation of the stitch. The part 103 does not press on the work but serves mainly as a guide. A thread-cutter 106 is attached to it. The work-plate 90 is slotted at 92 to receive the lower feed-dog 71 and at 93, 94 to receive the feeding-surfaces 200, 201. The looper 50 works in a slot 95 which is closed by a chaining-finger 97 around which the stitches remain for a short time after their formation. In order to ensure that the edges of the work are brought together without any curling, a special work-guide 120, Fig. 7, is provided. It comprises a central blade 140, and two resilient outer blades 141, 142, which are adjustably separated by a screw 143. The edges of the work are passed between the blade 140 and the outer blades and are guided by pins 148, 149. The rear ends 147 of the outer blades are adapted to uncurl the edges of the work, and points 150 further straighten and grip the work near the stitching point. The blades are upturned at 151 to facilitate the insertion of the work. The shank 120 of the guide is mounted for adjustment upon an eccentric 122, Fig. 5, turned upon the end of a cylinder 123 which is frictionally held by a spring washer and may be rotated about the pin 124 and clamped by a screw 131. Frames.-The machine frame is mounted upon a stand in a vertical or nearly vertical position.

Granted: 1907-06-20
Abstract: 18,690. Payne, R. H. Aug. 21. Cameras; dark slides.-Cameras adapted for taking a number of photographs on one plate, contained in a movable dark slide, are fitted with a screen comprising two relatively movable parts, suitably apertured. Fig. 3 shows an arrangement in which the front member D, having apertures D<1> as shown, is interchangeably mounted in a panel H which slides across the front of the second member, which has a single opening A<1>. A catch D<2> working in a gauge plate retains the panel in register. In the construction shown, three photographs could be obtained for each position of the dark slide. The screen members being interchangeable, other arrangements are possible. The dark slide is secured in the proper position by a spring bolt G, Fig. 6, on the camera back B interacting with interchangeable gauge plates F on the slide. In a modification, one part of the screen rotates instead of sliding across the other ; this modification is particularly applicable to cameras in which there is not sufficient room for the sliding screen. By fitting a false back, however, such cameras may be adapted to receive the latter form.

Title: Improvements in and relating to Electric Controllers or Switches.
Filed: 1906-11-08
Granted: 1907-11-08
Abstract: 25,202. British Thomson - Houston Co., [General Electric Co.]. Nov. 8. Switches.-Magnets for blowing out arcs in electric switches have their actual arc-extinguishing pole-pieces F, Fig. 3, embedded in sheets of insulation G, and are magnetized inductively by primary pole-pieces E, which form magnetic extensions of the solenoid core c. The invention is described in connexion with a drum switch having a separate blow-out coil for each contact-finger, and the insulation is designed to prevent sparking between adjacent blow-out coils. The blow-out solenoid is wound with a copper strip C, Fig. 2, which is connected at one end to a terminal post D, and at the other to the core c. Current passes through the coil, core, and polepieces E, and then in series through a finger B which presses on the drum. As the polarity of the magnet is reversed for each reversal of the current through the finger, the arc is always blown in the direction of the arrow in Fig. 2. The plate G for each coil is mounted on a support H, which can be moved so as to swing all the plates away from the contacts.

Title: Improvement relating to Three Colour-photography and to Plates and the like therefor.
Inventor: PFENNINGER OTTO
Filed: 1906-11-16
Granted: 1907-07-04
Abstract: 25,906. Pfenninger, O. Nov. 16. Colour photography; sensitized plates &c.-In the process of colour photography in which two of the component negatives are obtained simultaneously on two plates the sensitive films of which face each other, the colour filter commonly interposed is dispensed with, and the front plate is itself dyed with a colouring-matter or dye, which does not affect the colour sensitiveness of the plate, but converts it into a filter screen for the rear plate. For this purpose, the dye is chosen from such as are commonly used for colour filters, and is the dye which would be used for the filter in exposing the rear plate in other processes, in which such would be exposed separately and independently. The use of such dye also prevents any halation in the plate. The following Specifications are referred to: Nos. 5932 and 8956, A.D. 1893, Nos. 4606, 9270, 16,693, and 17,758, A.D. 1894, No. 28,920, A.D. 1897, No. 12,516, A.D. 1899; No. 11,719, A.D. 1901, No. 7924, A.D. 1903, No.: 20,827, A.D. 1904, No. 9246, A.D. 1905, and No. 25,907, A.D. 1906.
