Inventor: LEFEBVRE ALBERT
Filed: 1905-02-09
Granted: 1905-08-31
Abstract: 2625. Lefebvre, A. Feb. 9. Holding and picking-up tools, hand.-A pneumatic suction holding-tool for grinding o r polishing valves on to their seats is shown in Fig. 3. To grind or polish a valve, say of a explosion motor, the tool is placed on it and a blade e caused to engage a groove in the valve, while a projecting stem f on the blade e centres the appliance by engaging a central hole. A caoutchouc washer c extends upwards outside a short cylinder d in the form of an elastic tube g within the main cylinder a, the lower part of the tube being secured to the short cylinder by a wrapping outside an annular projection hand the upper end being secured to a plunger i slidable in the cylinder d and split in the direction of its length. This washer c is held firmly against the valve, while a handle l is raised until the ends of a pin m pass through slots (not shown), whereupon the handle is turned until the pin ends drop into notches n. By this means, a partial vacuum is obtained so that the washer c takes a firm suction hold on the head of the valve. A rapid rotary movement is then given to the handle, which causes the valve to rotate and to be ground on to its seat. To detach the tool, the ends of the pin m are disengaged from the notches n and turned and lowered through the slots above mentioned, to allow the elastic tube g to resile and draw the plunger i down and so destroy the vacuum.
