BLEEDER-VALVE.
SPECIFICATION forming part of Letters Patent No. 586,773, dated July 20, 1897. Application filed August 26, 1896. Serial No. 604,042. (No model.)
To (fill whom it may concern:
Be it known that I, XVALTER KENNEDY, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Bleeder-Valves, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a top plan view of my improved bleeder-valve. Fig. 2 is a central vertical section of the same; and Figs. 3 and at are vertical sections taken at right angles to that of Fig. 2 and showing the valve in open and closed positions, respectively.
My invention relates to that class of bleedervalves wherein the upper portion of the bleed er-pipe is fixed to a horizontal1y-reciprocating plate, the pipe registering with a hole in the plate, and its purpose is to avoid all danger of breakage of the parts when the valve is in closed position. To this end it consists in providing in that portion of the plate which closes the stack an explosion-door which will be acted upon by any undue pressure in the stack when the valve is closed and will open, so as to relieve such pressure.
In the drawings, in which similar numerals indicate corresponding parts, 2 indicates the upper part of the bleeder stack or pipe, this stack having bolted thereto by suitable flanges two oppositely-located plates 3 and at, which act as guides and rests for the bleedervalve 5. This valve consists of a flat rectangular plate, which is held in position by two bars or strips 6 6, which take over its side edges, as shown in Fig. 2. Upon the upper face of each of these strips is provided a stationary rack, and with these racks intermesh pinions 7 7, which are secured to a shaft 8, journaled in suitable bearings 9 9, mounted upon the reciprocating va1ve-plate.
To the protruding end of the shaft 8 is secured a sprocket-wheel 10, over which passes an endless chain, by means of which the shaft is rotated and the valve thus moved to its different positions. One portion of the valveplate is provided with an annular flange 11, to which the upper part 12 of the bleeder-pipe is secured, the flange surrounding the hole 16 in the plate, which registers with the stack when the valve is opened. The other portion of the valve-plate, to which my invention especially relates, is provided with a hole 17, which registers with the lower section of the bleeder-stack when the bleeder-valve is in closed position, this hole being normally closed by an explosion-door 13, which is provided with slotted lugs 14, surrounding the shaft 8, as shown in Figs. 3 and 1. To the upper face of this explosion-valve I preferably secure a bent leaf-sprin g 15, which, when the door is driven open, will contact with the upper part 12 of the bleeder-pipe and thus cushion the shock.
The operation of the device is apparent. \Vhen the bleeder-valve is in closed position and excessive pressure is produced in the blceder pipe or stack, the explosion-door 13 will first be forced upwardly, as a whole, at right angles to the plane of its seat, the slotted lugs 1% moving over the shaft 8. Then the lugs rise to a point where the shaft 8 strikes the lower walls of their slots, the door will then swing upon this shaft, and the spring 15 contacting with the upper section of the bleeder-pipe, so as to cushion the blow, the valve will then drop back upon its seat by the action of gravity.
The advantages of my invention will be evident to those skilled in the art, since all danger of breakage or injury to the parts consequent upon the accumulation of excessive pressure when the bleeder-valve is closed is done away with and such pressure automatically relieved.
The device is simple, cheap, and not liable to get out of order and performs its work effeetively.
Many'changes may be made in the form and arrangement of the parts of my device by the skilled mechanic without departing therefrom, since lVhat I claim is 1. The combination with a bleeder-valve consisting of a reciprocating plate arranged to travel across the bleeder-pipe, said plate having a hole arranged to register with the bleeder-pipe when the valve is in open position and having also a hole arranged to register with the bleeder-pipe when the valve is in closed position, of an explosion-door normally closing said latterhole and constructed and arranged to be opened by pressure Within said'pipe; substantially as described.
2. The combination with a bleeder-valve having a plate arranged to move across the bleeder-pipe, said plate having a hole which registers with the pipe when the valve is in open position, and also a hole arranged to register with the pipe when the valve is closed, of a swinging explosion-door pivoted to said plate and normally closing the latter hole; substantially as described.
3. A bleeder-valve comprising a plate arranged to travel across the bleeder-stack, said plate having a hole registering with an upper section of bleeder-pipe secured to the plate, and having also another hole which is normally closed by a swinging explosion-door pivoted to the plate; substantially as described.
4. A bleeder-valve comprising a plate arranged to travel across the bleeder-stack, said plate having a hole registering with an upper section of bleeder-pipe secured to the plate, and having also another hole which is normally closed by a swinging explosion-door pivoted to the plate, said explosion-door having a spring arranged to contact with the upper section of the bleeder-pipe when the door is driven open; substantially as described.
5. In a bleeder-valve, a reciprocatory plate having trunnioned in bearings thereon a shaft provided with pinions engaging stationary racks, and a section of bleeder-pipe secured to said plate and registering with a hole therein, said plate having another hole normally closed by an explosion-valve, said valve having slotted lugs taking about the pinion-shaft upon the plate; substantially as described.
In testimony whereof I have hereunto set my hand.
