Title: Improvements in Dental Clamps
Inventor: MCCARTER WILLIAM ARTHUR
Filed: 1903-02-17
Granted: 1903-04-23
Abstract: 3739. McCarter, w. A. Feb. 17. Teeth, stopping; dental instruments.-A clamp for holding a matrix plate or rubber dam in position on a tooth to be stopped is formed of two jaws A connected together by a bow spring B. The jaws are supported on the ends of the spring by ball-andsocket joints E, and the spring has guards G which bear against the outer faces of the jaws to prevent them from falling away from the tooth when in use. One edge of the jaws is somewhat longer than the other, so that, by reversing the clamp, teeth of different sizes can be treated. The ends of the jaws are curved round to form wings D, which increase their resiliency and at the same time steady the jaws by bearing on adjacent teeth. Plaques C on the edges of the jaws serve to grip the rubber dam. The inner walls of the jaws are concave transversely as wall as longitudinally.

Granted: 1906-07-31
Abstract: 15,640. Williams, H. A., Townsend, J. F., and Robinson, H. July 31. Brakes.-Relates to plate friction clutches in which the parts are engaged magnetically, the operating-switch being so moved by hand, or by cords arranged round the machinery, that the clutch is disengaged and a brake is applied to the driven member. The invention is applicable to motor road vehicles and to machinery generally. The driving-shaft 1, Figs. 1 and 2, carries a fixed pulley 2 and a loose pulley 3 which is adapted to drive the line shaft 2<1>, carrying pulleys driving the machines &c. 6. Switch-boards 7, 8, 9,10,11,12,12<1> are provided with switches 17, Fig. 4, which are connected by wires 14<1> to the points 18 on the next boards, a wire 14<11> connecting the switch on the board 12<1> with the lead 50, and the points 18 on the board 9 being connected by a wire 14 to a pole 15 which is connected to the coil 40<1> and thence grounded on the shaft 1, from which passes the wire 54, connected to the switch 37 on the main board 13, the point 40 being connected to the lead 41. A wire 22, which is connected to the pole 21 leading to the coil 62, is connected by wires 23 to the points 24 on the switch-boards. Connected to pawls 29, which hold the switches 17 on the points 18, are cords 25 which surround the machinery. Secured to the shaft 1 is a sleeve 54 which carries friction plates 43, carried by non- magnetic blocks 56, and adapted to engage plates 42 carried by similar blocks 58 on the pulley 3. Similar plates 52, 53 connect the pulley 3 and a sliding non-rotatable disk 51. To operate the clutch, the levers 17 are passed over the points 20 to the points 18, and the main switch 37 is similarly passed over to the point 40. If a person falls against one of the cords 25, the nearest pawl 29 is lifted, releasing the lever 17, which is pulled over to the point 24 by a spring 36 acting on a rod 33 pivoted to the lever, the pawl 32 retaining the lever on the point 24. The current then passes through the wire 22 to the brake coil 62, the plates 52, 53 then engaging and stopping the pulley. Wooden plugs may be inserted in the friction plates to increase friction. Figs. 9 and 10 show a modification. The casing 61, which is secured to the driven pulley 3, is adapted to be connected by two series of plates 67, 68 with the driving- pulley 2 and the fixed casing 64. A loose disk 65 carries pairs of rollers 66, 66', the outer of which bear on a cam track 63 in the casing 61, the inner bearing on the plates 67, 68. The disk 65 is engaged magnetically, by means of plates 42, 43, 52, 53, with the sleeves 71, 72, which are keyed to the pulleys 2, 64 respectively. By exciting the coils, the disk 65 is thus rotated or retarded, causing the rollers 66 to move along the track 63 and the rollers 66<1> to press one or other of the series of plates 67, 68 together and engage the clutch or the brake. Specification No. 7069, A.D. 1895, [Abridgment Class Mechanism &c.], is referred to.
