Description

Filed July :51. 1939 2 Sheets-Sheet 1 3.44m Hamer HSCaYS' Jan} 16, 1940. H.'H. scATEs HEAD GATE OR THE LIKE Filed July 31. 1959 2 Sheets-Sheet 2 Homerzfcaies Patented Jan. 16, 1940 UNITED STATES PATENT OFFICE HEAD GATE OR. THE LIKE 6 Claims.
My invention relates to a certain new and usein] device for cutting off and for regulating the flow of liquids from pipes. It particularly has for an object the provision of a simple, effective, 5 easily operated and inexpensive means for the purpose stated.
More specifically the invention comprises an end gate for water or oil lines so constructed and designed that by its use any desired quantity of liquid may be regulated to flow from the pipe, from a maximum to zero.
It also has for an object to provide a means whereby the device can be used as a head gate, or a means whereby a smaller pipe may be operatively coupled to the end of a larger pipe and the pressure of the fluid at the intake end of the smaller pipe can be regulatedby opening, more or less, the head gate.
Other objects will in part be obvious and in part be pointed out hereinafter.
To the attainment of the above objects and ends the invention still further resides in the novel features of construction, combination and arrangement of parts, all of which will be first ll fully described in the following detailed description and will then be particularly pointed out in the appended claims, reference being had to the accompanying drawings, in which:
Fig. 1 is a-side elevation of my-invention in use, the gate being in the closed position. ,Fig. 2 is a central vertical longitudinal section of the same, the gate being partly open in full lines and all the way open in dotted lines.
Fig. 3 is a top plan view of Fig. 1. Fig. 4 is an enlarged cross section onithe line l| of Fig. 1, the padlock being omitted.
Fig. 5 is a detail perspective view of the cap block with hood omittedl 4 In the drawings, in which like number-s ot refthe pipe, duct or conduit whose outflow is to be governed bymy device.
My device comprises a special quickly attachable and detachable clamp composed of a bottom member 2 having threaded studs 3 in axial align- ,ment, and two quarter-section members 4 having apertured ears 5', the latter fitting the studs 2, whiie'the former receive the bolt, with nut, 6 by which the members 2 and I are secured rigidly around the pipe I. s I designates the cap block which is designed to be held over the opening in the end of the pipe. It has a facing 8 of rubberized fabric, rubber, leather or other suitable material to make a water-tight contact with the pipe end when erence indicate like parts in all the figures, I is the cap block I is forced toward the pipe end. The block 'I is provided with a hood I that fits over the pipe (see Fig. 1) and acts also as a stop.
The block I has a metal face 24- held to the block by cars 35 and by bolts 33 with nuts 36 that also secure the plate 32 and facing 8 to the block (see Fig. 5).
At the sides of the block are secured at 9 the arms II) which extend back along the sides of .the pipe and have slots I I to receive the studs 3. The connection between arms Ill and block I is preferably a rigid'one, although it may be articulated if desired. There, is an arm III at each side of the pipe I.
To the rear ends of arms I Ii are pivoted the forked ends I2 of a lever 29. This lever is provided with a handle I6, ratchet teeth I5, and holes I4, and extends through an arm 20 which comprises the holding arm. The lever holes I4 are designed to receive a padlock so that the lever arm can be locked against movement in a direction to open the outlet end of pipe I.
The arm 20 is also bifurcated and pivoted at its-forked ends to thestuds 3. It is also provided with cross bolts, screws or rivets 2I to limit up and down movement of lever 29. The arm 20 carries a pawl 23 pivoted at and held normally in engagement with rack teeth I5 by a coil spring 24. The pawl 23 may be lifted by a rod 25 that passes through a spacer 28 in the arm 20. The arm 20 also has a handle 21 and the rod 25 has a finger piece 26. Pivoted at I8 to each'furcation I2, is a link II having a slot I9 to receive the stud 3.
If desired, a small pipe fitting 30 with needle valve II may be tapped into block I and communlcate' with pipe I when the same is capped.
Operation Assume the parts to be positioned as in Fig. 1 with pipe I entirely closed. To open the pipe it is only necessary to raise latch pawl 23 via rod 25 and then to swing arm clockwise in Fig. 1 to the dotted line position shown in Fig. 3, and then lift up on lever 29. Lifting lever 29 causes it to act as a fulcrum, and rods I I) are pushed out, thus separating block I, B from the end of pipe I, and also, on further movement, raising end, all flow will cease. When valve II is opened, fluid will flow via fitting 30.. If pressure is too great with valve 3| fully open, it may be reduced by moving block 'I more or less away from the end of pipe I to permit liquid to leak out between packing 8 and pipe I.
From the foregoing description, taken in connection with the accompanying drawings, it is thought the construction, operation and advantages of the invention will be clear to those skilled in the art, and I wish it understood that changes in the details of construction and form of the parts may be made without departing from the spirit of the invention and the scope of the appended claims.
