GATE-VALVE.
SPECIFICATION forming part of Letters Patent No. 600,363, dated March 8, 1898.
Application filed September 9, 1897. Serial No. 651,099. (No model.)
To all whom it may concern:
Be itknown that we, ALFRED N. HEINE and YVILLIAM K. 11. WOERNER, of Evansville, in the county of Vanderburg and State of Indiana, have invented a new and useful Gate- Valve, of which the following is a full, clear, and exact description.
This invention is a gate-valve capable of controlling the inlets and outlets of a valve having a plurality of ways such, for example, asa four-way valve-the apparatus having one or more gates and having means by which the gates may be adjusted about the several ways.
This specification is a disclosure of one form of our invention, while the claims define the actual scope of the conception.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.
Figure 1 is a vertical section taken through the Valve. Fig. 2 is aplan View with the dome removed and showing the gates in operative position. Fig. 3 is a fragmentary view illustrating the gearing for adjusting the gates. Fig. 4is a face view of one of the gates. Fig. 5 is a face View of another of the gates. Fig. 6 is a detail perspective View showing the head of the adjusting-shaft, and Fig. 7 is a perspective View illustrating the wrench by which said adj ustingshaft is operated.
The valve-casing 10 has four necks 11, effecting connection with a like number of conduits 12. The necks 11 lead to the interior cavity 13 of the casing, and the four walls of said cavity are respectively provided with wear-plates 14, forming valve-seats against which the gates, hereinafter described, bear to close the necks. Below the lower edge of each wear-plate 14 a stop-lug 15 is fixed, such stop-lugs serving to limit the downward movement of the gates, whereby said gates may be held in operative position. The interior cavity of the casing 10 has an open top covered by a dome 16, said dome forming a cavity larger than the interior of the casing 10. The dome 16 carries the means for carrying and adjusting the gates.
Mounted in the top of the dome 16 and held to turn, but not to slide therein, is a vertically-extending shaft 17', having a square head to permit the shaft to be operated by a wrench. The shaft 17 extends centrally through the dome and down into the cavity of the casing 10 and is screw-threaded below the collar 18, formed on the shaft 17 at a point within the dome 10. Carried loosely on the shaft 17 and resting on the collar 18 is a disk 19, to which two downwardly-extending guide-rods 20 are fixed. Screwing on'the shaft 17 and guided by the rods 20 is a nutblock 21, having at each of two opposite sides two pins 22, respectively receiving verticallyelongated slots 23, formed in the gates 24 and 25. The gates 24 and are thus mounted to have slight vertical movement on the nutblock 21 and are carried up and down in and out of the casing 10 by means of said nutblock, which in turn is moved by the action of the threaded shaft 17, turning in the top of the dome 16. As the nut-block 21 moves into the casing 10 the gates 24 and 25 are seated upon two of the four wear-plates 14. The lugs 15 stop the downward movement of the gates 24 and 25. The gates are wedged outward against their seats by means of inclined lugs 26, formed one on the inner face of each gate and bearing against inclined surfaces 27; formed on the nut-block 21. Consequently after the gates are once engaged with the lugs 15 aslight downward movement of the block 21, independent of the gates, will force the gates outward and cause them to be hermetically seated on the wear-plates 14.
n For the purpose of turning the disk 19 to adjust the position of the nut-block 21 and the gates 24 and 25 and also for the purpose of holding the disk 19 stationary, so that the guide-rods 20 may perform their requisite functions, we provide a gear-wheel 28, fixed four peripheral recesses 33, capable, respectively, of receiving the blocks 29. The gear 31 is mounted to turn on a stub-shaft 35, depending from the top of the dome 16. The gear 31 has four equidistant mutilations 34, designed, respectively, to receive the giant teeth 30 and also to receive the pairs of giant teeth 36 of the gear 37, fixed on a shaft 38, revolubly mounted in the top of the dome 16. A ratchet-wheel 36, fixed on the disk 32 and engaged by a pawl 42, prevents back movement of the disk. The disk32, bearing at its periphery against the blocks 29, prevents the rotation of the gear 28 and consequently holds the blocks 21 firmly from turning. When the gear 31 and disk 32 are turned, the disk 32 slides around the blocks 29 until one of the giant teeth 30 engages the wall of one of the mutilations 34, whereupon the adjacent block 29 will be in position to pass into a recess 33. This allows the wheels 28 and 31 to mesh, and the wheel 28 may then be driven. The wheel 31 is driven from the wheel 37, and the latter Wheel is provided with the giant teeth 36 to prevent missing mesh at the mutilations 34. The shaft 38 has asquare head 39,provided with a vertically-extending spline 40. adapted to be engaged by a socket-wrench 43, the socket of which has a groove 44 to receive the spline 40, and the handle of which has one end pointed, as shown at 45. The single wrench shown in, Fig. 7 can be used successively for both shafts l7 and 38, therewrenches. The shafts 17 and 38 are provided with stuffing boxes above the top of the dome 16.
In operating the valve the shaft 17 is turned to raise the nut-block 21 and the attached parts upward into the dome 16. The shaft 38 is now turned to adjust the nut-block 21 and the gates 24 and 25, so that the gates will be located in the proper position for closing the desired necks 11. In order that the position of the nut-block 21 and gates 24 and 25 within the dome may be determined from without, we have provided the spline 40 on the shaft 38 and the slot 44 and the pointed handle end 45 on the wrench 43 These parts, when given a proper and known relative relation, will indicate exactly the position of the gates within the dome. After the gates have been adjusted the shaft 17 is turned again to move the nut-block and the gates downward and seat the latter.
If desired, both gates may be solid, so that two necks 11 will be closed; but this is not generally necessary, and the preferred construction is that which provides the gate 24 with orifices 46, (see Fig. 4,) in which case the gate 24 serves merely as a means for receiving the side pressure of the nut-block 21 as the same moves downward to force the gate 25 into place against the coacting wear-plate 14.
Having thus described our invention, we
claim as new and desire to secure by Letters Patent 1. The combination of a threaded and revoluble shaft, a nut-block threaded on the shaft, a valve-gate carried by the nut-block, the nut-block and valve-gate being moved vertically to seat and unseat the valve-gate, and means for turning the nut-block and valve-gate to adjust the valve-gate.
-2. Thecombination of a threaded and revoluble shaft, a nut-block threaded on the shaft, a gate carried by the nut-block, a disk loose on the shaft, a guide-rod fixed to the disk and engaged by the nut-block, and means for turning and holding the disk.
