' CAN TRANSFER VALVE Fil ed March 12, 1935. 2 Shgets-Sheet 1 I v INVENTORQ {Zena/ Mariam Patented June 8, 1937 UNITED STATES PATENT OFFICE CAN TRANSFER VALYE ration of Delaware Application March 12, 1935,. Serial No. 10,742 In Great'Britain March 22, 1934 16 Claims.
The object of'the present invention is to provide an improved construction of valve which effects the automatic ejection of the cans therefrom where desired.
A rotary can-transfer valve in accordance with this invention comprises a fixed lower plate over a which a vane-like wheel or propeller mounted on a vertical spindle is rotated so that the cans between the vanes or radial arms of the propeller rest upon and slide over the plate, and means for-retaining the cans within the divisions of the wheel or propeller between the feed and delivery positions, the plate having its surface inclined or sloping at the place where the cans are to be delivered so that when a can in its movement rides on to such inclined or sloping surface, it has a definite outward thrust imparted to it by the propeller which will deliver it from the valve.
The invention further comprises the arrangement in which the fixed plate has inclined or sloping surfaces at opposite sides of the propeller axis to serve for the feeding of cans on to the plate and for the delivery of cans therefrom respectively, the peripheral surface of the vanelike wheel or propeller between such feed and delivery points coming within can retaining walls which make a joint with the vane wheel.
The invention further comprises the arrangement in which the means retaining the cans within the wheel or impeller between the'i'eed and delivery positions comprise spring loaded parts which press upon the edges .of the vanes or arms of the propeller.
The invention further comprises the arrangement in which the fixed plate is a circular disc with flat or cut away sides at the feed and de- 50 livery positions so that feed and delivery endless conveyors can come alongside a straight part of the plate.
Referring to the two accompanying sheets of explanatory drawings:-
Figure 1 is a sectional plan view of a valve constructed and arranged in one convenient form in accordance with this invention- Figure 2 is a sectional elevation on the line 22 of Figure 1.
Figure 3 is a plan view of the plate over which the cans are moved by the vane-like wheel or propeller.
Figure 4 is a sectional view on the line 4-4 of Figure 3.
The valve proper comprises a vane-like wheel or propeller a open at its periphery and keyed upon a vertical shaft b which is rotated by suitable means, and a fixed plate 0 upon which the cans rest as they are moved from the inlet to the delivery side of the valve.
The wheel or propeller a turns within a casing consisting of two parts d, 6, each with a spring loaded and detachable liner or shoe j thereon which bears against the tips of the propeller blades to make a joint therewith. The springs by which the liner parts I are loaded are shown at g. Each liner f is keyed to the casing by a key shown at h in Figures 1 and 2.
The plate 0 is secured to the part i of the valve casing which provides a bearing for the lower end of the shaft b. The right hand side of the valve in Figure 1 is the feed or inlet side and the left hand side is the discharge or outlet side. At the inlet side, the plate 0 gradually slopes away or thins down from the point a; to the edges Y and Z, the edge Y being thinner than the edge Z. At the delivery side, the plate slopes away or thins down from X to Y Cans which are to be fed into the valve are carried on plates 1 on an endless conveyor k and are pressed into the divisions of the vane wheel or propeller a by a worm m which is set at an angle to the conveyor k and is timed in relation to the shaft b so as to ensure that a can is passed into each division of the vane wheel or propeller a. The cans travel up the inclined surface of the plate 0 from Y to X and then are carried around by the vane wheel or propeller past the liner f until eachcan comes to the sloping delivery surface of the plate, where as there is no enclosing wall at that part, the can glides naturally off the plate and on to a plate 12. of the conveyor, 0 under the action of the vane wheel. It will be seen, therefore that the inclination of the surface of the plate c at the can delivery position serves in conjunction with the propulsive action of the vane wheel to deliver the can off the plate 0 without the use of extraneous extracting devices; thereby simplifying the construction 0! the valve.
The casing for the vane wheel or propeller has a cover piece p thereon which provides a bearing at q for the shaft b and a stufl'ing box at r, for said shaft. The vane wheel provides at all times a complete closure between the can inlet and delivery positions.
The mounting of the propeller a within the casing is such as to leave an enclosed chamber s between the propeller cover a1 and the casing cover p. When the valve is'used to transfer cans under the pressure of steam, air or other pressure medium, the chamber s serves to accumulate such pressure medium as escapes thereinto past the running joint between the propeller and valve casing, and the pressure thus built up in said chamber serves to hold the propeller vanes in pressure tight contact with the stationary plate c. The plate c can be renewed when worn.
