To all whom it may concern:
Be it lmown that I, EDWARD S. CLARK, a
citizen of the United States, residing at Boston, in the county of Sufiolk and State of Massachusetts, have invented new and.
useful Improvements in Valve-Operating Devices for Fluid-Conduits, of which the following is a specification.
My invention relates to valve operating devices forfluid conduits; and its objects are to reduce the damage due to breaks and to conserve the supply of fluid, to speedily regulate the volume'of fluid, to facilitate the testing of the gates used for opening and closing the conduit, to open and close said gates with the rapidity required in emergencies, to utilize and apply a source of power other than manual means, to make the device adjustable and quickly available for practical use, to stop the operation of the device automatically when the gates are fully open or closed, and to produce a device which is simple and economical in construction and in other ways eflective in the relation for which it is designed.
At the present time it is the general custom in the great cities to use for opening and closing large water or gas mains at points'of the line where it is deemed desirable, gate valves of heavy construction. In the case of water mains these are ordinarily thirty-six inches in diameter, and are closed by a gate wrench which requires about three hundredturns thereof and the work of four men laboring continuously for about fortyfive minutes for its efiective operation. Such labor is very severe, and where it is necessary, as often occurs, to close several gates, the efficiency of the men becomes greatly reduced with each successive. gate, and if the number of gates is further increased, the men become exhausted and must be given a period of rest perhaps at a time when delay may mean the loss of life or property. This will be readily appreciated if it be borne in mind that in the case of a complete break the escape of the water from a large main would be in the vicinity of fifty thousand gallons a minute, all of which must find some outlet to the damage of property owners in the vicinity. .Then again in'case of fire, it becomes necessary to act promptly with reference to the gates not only to prevent the waste-of water in the fire district through breaks where it is diverted from effective use, but also to allow the full head of the water to be utilized where it is. most needed.
My Invention primarilyv consists in mounting a universal wrench socket, which is made self adjusting, upon a motor vehole, and, to operatively connect to its source of motive power, mechanism for turning the said wrench socket.
My invention further consists in the various improvements and novel'arrangement of parts hereinafter more fully set forth or llustrated in the drawing and referred to in the claims.
Through the use of my invention in connection with a motor truck under the conditions of actual use, I have found that the work of'closing the gate valves which for ing in whichsimilar numerals of designation refer to similar parts throughout the several views.
Figure 1 is a plan of the frame of the chassis showing the casing of my improved Wrench socket and its relation to the main shaft; Fig. 2 is a side elevation of a motor truck to which the turning mechanism of my improved Wrench socket is secured; Fig. 3 is a horizontal section of the mechanism and connections adjacent to the main shaft; Fig. 4 is a plan view of the turning mechanism shown partly in section with the up-.
per hemisphere of the casingof the wrench socket removed; Fig. 5 is a vertical section on line 4-4015 the view shown in Fig. 4, looking in the direction of the arrows, and Fig. 6 is a side elevation of the universal joint at the lower end ofmy wrench.
Referring to the drawing: Upon the chassis frame 7 of the motor truck 8, I
mount in any suitable manner the casings 9 and 10 containing the mechanism for turning the wrench 11, the casing 9 being preferably secured to the said frame by means of the brackets 47 and 48, and the casing 10 inclosing a portion of the driving mechanism connected with themain shaft 50,. and being preferably secured to said frame by the arms 14 and rigidly connected to the special construction transmission casing 51 bylugs 49-orother suitable means. The portion of the driving I mechanism within the casing 10 is made'of to meet with the requirements of my invention. (See Fig. 3.) To thesquare tapering end 12 of the shaft 25 is secured the socket 15 of the rectangular insert 16, which is shaped to register and r to revolve therewlth. lnclosing the wall of said socket 15 is the collar 17 freely rotating on the ball bearings 18 and held in operative position by suitable means and bearing the bevel gear 19 which is bolted there- .to. The inner portion of the collar 17 is constructed in the form of a gear or clutch 20 shaped to engage with the clutch 21, which slides longitudinally upon the rectangular insert'lfi and rotates therewith. At
the other end of the said insert 16 are the ball bearings 22' installed within the clutch or gear 23 ournaled in the ball bearings24 secured to themain frame, and which clutch 23 is integral and rotates with the square tapering end 13 which is normally affixed to the main shaft in the rearward part of the truck. As will be well understood by persons acquainted-with the art, the movement of the clutch-16 well to the left will cause engagement and rotation of, the bevel gear 19, while the movement of said clutch well to the right causes the rotation of'the said shaft 50.
' Meshing with the bevel gear 19 is the bevel gear 26 mounted upon one end' of the countershaftv 28 which is journaled in the ball bearings 27 mounted-upon the casing 10. I The remainingportion of said countershaft 28 carries the worm 29 and is journaled 1n the ball bearings 30 and 30 mounted within and upon thehousing32, the ball bearin'gs 31 similarly mounted serving to take-up the end thrust of said countershaft. Preferably the extreme end 52 of said portion of said countershaft is made square in order to afiord an opportunity for the application and'use of ahand wrench if desired. Meshing with said worm 29 is the worm gear 33 which is bolted to the two parts of the sleeve '34 mounted within'the casing 9 and rotating uponball bearings 35. Within the sleeve 34 is the circular frame 36 having at opposite parts of its circumference the bearings 38,
which engage with the trunnions 37 firmly secured to the inner portions of said sleeve.
v the socket 41; the object of which is to allow considerable play ofthe wrench 11, and to permit the same to adjust itselfautomatimeter? cally, to varying conditions. In order to revent the escape of the lubricating oil used or the bearings within the casing 9, l preferably employ the screw ring 53 which is threaded to engage with the lowest part of the lower hemispheres of said casing, and to hold the packing in place.
Preferably the casing 9 is constructed of hemispheres with wide flanges as shown bolted together at the line of juncture. in order to prevent any strain or breakage of machinery, I prefer to construct the lower part of my improved wrench, containing the jaw 44, with a universal joint 45 provided with a pin 43 of copper, soft iron or other material of a torsional strength somewhat less than the teeth of the gears of my turning mechanism above despribed (see Fig. 6), so that if .by accident the operation is pro tracted after the gate has been fully opened or closed the pin 43 will break and the fun ther application of the power to the gate will be discontinued. Normally when the wrench is not in use, it is carried in the position shown in Fig. 2, a clamp 46 or any other suitable means being employed for suspending the same.
As is obvious, my device may be adapted and applied for operating any gate, door, valve, plug or other means for stopping the passage of steam, illuminating gas, oil, water or other fluid through a conduit or other aperture, and by the term wrench valve as used in the claims, I desire to be understood as including within its scope and meaning any such gate, door, valve, plug or other means employed for such purpose and of such construction as to be susceptible of being actuated through the application of a wrench of the general character above set forth and described.
The operation of my invention is as follows: The motor truck shown in Fig. 2 is driven into such position as to bring the wrench socket directly over the man hole of the gas or water gatewhich it is desired to open or close; the'man hole cover is removed, and the wrench is slipped through the said socket andbrought into engagement with thenut on the gate gearbelow. The clutch 21 is then moved into engagement with the clutch 20 and the bevel gear -19 is caused to rotate, and through the transmission gears above described, to turn the wrench socket 41 and the wrench 11 therein, thereby turning the said nut and opening or closing the gate as desired. Care should preferably be taken, however, that the operation does not proceed sofar as to go beyond the complete opening 'or closing of the gate so as to cause the breaking of the pin 43; and in practice with unskilled workmen I prefer to have them stop somewhat short of this point and to leave the last few turns to be accomplished by a hand wrench ap-' Y 1 number required to close any type of gate being generally known.
