Filed: 1947-12-02
Abstract: 636,982. Moulding reflectors &c. HOLOPHANE, Ltd., and HOLMES, J. G. Dec. 2, 1947, No. 31835. [Class 87 (ii)] [Also in Groups XI and XXIII] In a method of manufacturing reflectors or refractors, a plate of plastic transparent material with a prismatic surface of flat or slightly curved contour is bent to a final contour, the original shape of the prisms being such that after the distortion due to bending the plate, the prisms have the desired shape. The bending may be produced by moulding under pressure where the transparent material may be reduced to plastic condition to permit deformation. To control the change in shape of the prisms, the deformation may be limited by a support which may be grooved to receive the final section of the prisms, or a flexible metal sheet may remain in contact with the prism during bending. In addition to the prism on one side of the plate a diffusing pattern, comprising ribs or flutes may be provided on the other side or prisms may be provided on both sides which complement one another in redirecting the light. Prisms on one side may cross prisms on the other side at 90 degrees or some other angle (see Group XXIII).

Filed: 1922-11-27
Abstract: 210,222. Curtis, J. N., and Curtis, J. J. Nov. 27, 1922. Force-transmitting mechanism. -Relates to transmitting-mechaniism for vacuum brake gear and comprises means for increasing the initial travel of the pull-rod to take up the slack in the rigging with subsequent increase in the brake leverage to compensate for loss of power in the cylinder when wear on the brake shoes increases the stroke of the piston. In the form shown, power is transmitted by the lever 2 through the shaft 3 to the two arms 4, 5 of a bell-crank lever. The arm 5 is connected through a link 10 with a link 6, ona end of which is connected to the pull-rod 21, whilst pins 9 on the other end carry rollers 20, which run in an inclined slot 7 to a horizontal slot 19 in a bracket 8. Initial movement of the lever 2 causes the rollers 20 to rise in the slot 7. and the link 10 causes rollers 17 carried by the pin 11 to ride over a shoulder 13 on the arm 4, whereby the travel of the rod 21 is increased. In the continued movement of the lever, the rollers 20 pass into the slot 19 and the rollers 17 move along the curved face 16 of the arm 4, whereby increased leverage is obtained. The radius of the curve 16 is so designed that very little power is absorbed by the arm 5 after the slack in the rigging has been taken up, the link 10 having a pin-and-slot connection with the link 6 for the same purpose.

Title: Improvements in and relating to funnels for liquids
IPC: B67C11/06
Filed: 1920-11-18
Abstract: 172,210. Barron, R. Nov. 18, 1920. Funnels.-A funnel is provided with a float which, when the liquid has risen to a predetermined point in the vessel, acts through the lever devices described below to release a valve which closes the neck of the funnel. The float 12 is housed in the stem 15 of the funnel, and is connected by links 14 with the outer ends of levers 7 pivoted at 8 in a cylindrical enlargement 11 of the stem. When the stem of the funnel is not immersed in liquid, the weight of the float brings the inner free ends 6 of the levers close together, as shown, and they support the stem 4 of a valve 3 and thus keep the valve off its seating 2. In use, when the liquid in the vessel that is being filled rises in the neck, the float 12 is lifted, and when the level of the liquid reaches a predetermined point, the height of the float is such that the valve stem 4 can fall between the ends 6 of the levers 7, and the valve closes and prevent more liquid from running out of the body of the funnel. The valve can be reset, when the funnel is lifted, by pulling the stem 4 upwards. In a modification, the float is connected to a single lever, the free end of which supports a disc on the lower end of the valve stem, but releases it when the float rises.
