STOGI I-WATERIEG BOWL.

Application filed august My invention has relation to improve ments in stock watering bowls.

In devices of this character, it is u desideretuin to provide for ready removebility of the bowl tor cleaning purposes, and also for ready replacement of the bowl, after the cleaning operation has been performed.

it is important in n. bowl of this character, after it is adjusted to position ready for use, that it be held tirrnly in said position, against th possibility of being moved in tiny direction, and to avoid the possibility of its being nccidentully detached owing to pressure exerted by the nose or" the cow, when the cow inserts her head in the bowl.

It is one of the objects of this invention, to provide an improved means of connection between the supply pipe and the bowl, whereby when the bowl is in its utteched position, there is no possibility of the bowl being moved in any direction by pressure (,jitl'llttl by the enunnl, while yet the easy :ltuchnu'nt end repl tllH-Jllh of the bowl is not interi'ered with.

The invention further eonteniplutes iillpJ'OVGLl vulve o icruting lllGtJlS, which not only provides tor eesy manipulation of the valve ineclumisin by the uniu'iul, but fun thermore provides for easy and repid removal or ediustn'ient of the valve mechanism, when it is desired to gain access to all puns ot the bowl for cleaning purposes.

A still further important object is the provision of o, construction whereby the iiec it-y o'l inuchininp; of the ports rendered unnecessary, inasmuch us the construction of my llllPlOv-ttl bowl is such that the di'll ercnt component parts thereof may is cast and the machining operation dispensed with.

With the above nuun objects and other incidental objects in vi w, the invention consists of the devices and ports and all equivalents thereof us hereinafter more fully set iorth.

valve mechanism being removed, the supply pip-e being in horizontal section as indicated by the dotted lines 33 of Fig. 1, and an adjusted position of the supply pipe being shown by dotted lines; and

l is a detail View of the pivot pin and valve-operating mechanism mounted there on.

Referring to the drawing, the numeral 4; indicates the bowl, said bowl being provided at its rear with an extension 5, preferably psrtly circular in cross section, to conform to the circular contour of the in uer leg of the supply pipe. This extension is provided at the center of its upper edge with e rearwurdly projecting horizontal hp 6.

The rear portion 01" the bowl, where the extension 5 opens into the bowl, is provided with vertical ribs 7--7, each rib being formed with a verticully-extending recess 8.

'i. he supply pipe is indicated by the nu inerul fl, and is of the usual inverted U- shuped form of construction.

The outer leg; of this supply pipe has projecting from the inner side thereof two spaced-spurt horizontally extending lugs 10 and 10. The lower lug it) bears against the outer surtuce oi the circular extension 5 of the bowl, and the upper lug 10 also bears against said surface, and furthermore, when the bowl is adjusted to the pipe to its normal position, it fits beneath the resrwardlyextending; lip 6,0-f the bowl, said lip 6, restins; upon said lug 10.

Suitably bolted to the outer leg of the sup ply pipe, and extending; diagonally therefrom is e. clevis 11, the inclined position oi which renders it capable of engaging either verticol or horizontal post or other supporting! ineoiuin, whereby the supply pipe is held lirrnly in supported position.

Either end of the outer leg of the supply pipe may be connected to a source of water supply, threaded openings in the opposite ends of said outer leg being provided for that purpose. As shown in the drawing, the connection should he needs at the lower end of the outer leg of the supply pipe, said lower end being open and interiorly threaded. A similar threaded opening is provided at the upper end of the outer leg of the supply pipe, and a. screw cap 12 is shown us closing: this upper opening. Vi hen, however, it is desired to connect the upper end tit] of the outer leg of the supply pipe to the source of water supply, the cap 12 removed from the upper opening, and screwed into the lower opening.

The inner leg of the supply pipe, at the upper portion thereof, is provided with oppositely-disposed laterally-extending lugs or ears, 13-43. which, when the bowl is in its normal position for use, rest upon the upper edge of the rounded extension of the bowl.

Also the inner side of the inner leg is formed with a lug 14, the function of which will be hereinafter set forth.

The valve-casing is indicated by the numeral 15, said casing having a threaded connection at its low-r end with the lower end of the inner leg of the supply pipe. The valvecasing near its lower end is provided with an annular flange 16, which e3:- tends beneath the lower end of the inner leg oi the supply pipe, a packing 17, being interposed between the two.

The upper end of the valve-casing is provided with an opening 18 through which water from the supply pipe may flow and enter said valve-casing. The valve-opening is controlled by means of a tapered plug valve 19. The stem of this valve is made of 5 two parts, viz, an upper part 20 depending from the valve, and a lower portion 21 articulating with said upper part, and projecting downwardly below the lower end the inner leg of the supply pipe.

The opening oi? the valve is controlled by m ans of a pressure plate 22, which plate is operated by the pressure of the nose of the cow downwardly on said plate. The main portion of the plate is provided with spaced-apart cross bars, to permit of the water flowing upwardly through the spaces between said bars. Projecting from one side of this main portion 01" the pressure plate are two upwardly curved arms 2"-23, having upwardly-extending ears 24-42%, said ears being provided with vertically-elongated slots 2"25, which receive loosely therein a transverse pivot pin 26. The central portion of said pin which lies between the arms is offset to form a crank-like formation or bond 27. The ends of this pin extend outwardly laterally through the elongated slots 25, and loosely in the vertical recesses 8, so as to be capable of movement vertically in said recesses.

Connecting the two arms 23 beyond the lugs 2 1- is a cross member 28, having projecting from the center thereof, a finger This linger, when the parts are in operative position, extends beneath the lower end of the lower valve stem member 21, so that when the outer end ot the presser plate is depressed, said plate will turn on is pivot and cause the iinger 29 to turn upwardly and act against the lower end of the valve stein member 21, and raise the latter so as to cause an up movement of the valve 19 and consequent uncovering of the valve opening 18. The water is then free to flow from the supply pipe into the valve casing, thence through the lower open end of said easing into the bowl. lVhen the cow ceases to press upon the presser plate, a coiled spring 30 which encircles the valve stem member 21, expands and causes a descent of the valve and a closing of the valve opening 18.

It will be noted that when all the parts are in their assembled condition, the off set or crank-like tormation ot the pivot pin .44 is beneath the lug 14 formed on the inner side or face of the inner leg of the supply pipe, the lug. by reason of its fitting within said ofi set portion of the ivot preventing upward movement of said pin within the vertical recesses 8. At times it is important that the presser plate be adjusted, and held in such position as to prevent the cow from operating the same. In order to accomplish this, all that is necessary to be done is to tilt the presser plate slightly to the extent permitted by contact of the finger 29 of the presser plate with one side of a lug 31 upstanding from the bottom of the bowl. The cranked or oil set central portion :27 of the pivot pin is next grasped, and turned so as to bring said oii set portion from beneath the lug 14.

The pin being ield in its ontturned position and the presser plate in its slightly tilted position, by the fingers, the said parts are then raised, the ends of the pin, of course, being free to move upwardly in the recesses 8. rfter being raised a desired distance to bring the finger 29 above the upper edge of the lug 31, the presser plate is then free to be turned to a full vertical position, which. vertical position brings the finger 2-9 in line in advance oi the lug 31. The pin and presser plate are then lowered until the finger E29 strikes the bottom of the bowl, and the presser plate having been turned to a vertical position, the said linger when the plate is so lowered is brought in advance of and in engagement with the lug 31, and hence the presscr pla e is held in its adjusted vertical position, vhere it is impossible tor a cow to operate the same.

It will be noticed from the Figure l of the drawing that each straight end of the pivot pin is provided with a lug These lugs are so positioned as to be located within the elongated slots 25 of the ears 24, and act as stops to limit the extent of the movement of the presser plate in either direction.

Frequently sediment accumulates in the water which enters the supply pipe, and as it is desirable for the water which enters the bowl to be clean possible, and tree from all sediment, I prefer that the valve casing be covered with a reticulated or screened covering 33, the lower edge of which rests upon an annular shoulder 34 formed on the valve casing.

Vitith my improved construction, it will be seen that the presser plate and its pivot pin can be readily removed, all that is necessary to be done being to turn the pivot pin sufliciently to bring its offset or cranked portion out of engagement with or from beneath the lower end of the lug 14. The pin and presser plate can then be raised, the ends of the pin moving in the vertical recesses until the upper open ends of said recesses are reached, when of course the pin can be removed and with it the presser plate. If desired, after the removal or" the pivot pin and presser plate, said pivot pin can be removed or disassembled from the presser plate merely by turning the pivot pin so as to bring the olfset portion thereof in line with the vertically-elongated slots 25 of the ears or lugs 24, and the pin can then be readily pulled through said slots.

It is further to be noted that when the presser plate and pin are removed as previously explained, access to the valve casing and related parts is made possible, and. the valve casing and valve removed for cleaning, or other purposes, merely by unscrewing the valve casing.

If it is assumed. that the parts-are in the position shown in Figure It, and it is desired to remove the bowl for cleaning purposes, the first step necessary to be taken is to remove the presser plate and pivot pin in the manner previously explained. After these are removed, the bowl is then free to be turned. The bowl is turned suiticiently to bring the lip 6 thereof from its normal position above the upper lug 10 of the outer leg of the supply pipe. It is evi dent that there is then no impediment to the complete downward withdrawal and disconnection of the bowl. After such disconnection, the bowl can be taken to a point outside of the stall for cleaning purposes, and the soiling of the floor of the stall by splashing water which would result if the bowl were cleaned in the stall, is avoided.

After the cleaning operation is completed, the bowl is brought back to the stall and raised upwardly between the legs of the supply pipe, with the bowl so positioned that the lip 6 is out of line with the lugs 10 and 10 of the outer leg of the supply pipe. After the bowl has been raised to such an ex:- tent that the upper edge of the rear projection thereof is in contact with the lateral cars 13 which extend from the inner leg of the supply pipe, the bowl is then turned so that the lip 6 is brought to a position above and resting upon the lug The presser plate and pivot pin are then readjusted to place in an obvious manner.

It will be evident that the bowl cannot be raised or tilted by pressure exerted by the cow beneath the bottom of the bowl in view of the fact that the projecting lip 6 is immediately below and in contact with the underside of the connecting portion between the inner and outer legs of the supply pipe, and also by reason of the provision of the ears 18.

It will be furthermore evident that the bowl cannot be given a sidewise swing when pressure is exerted by the cow upon the inside wall of the bowl by reason of the pro vision of the lugs 10 and 10, and also by reason of the nuzre or less close fit of the inner leg of the s oply pipe between the walls of the curved or; nsion of the bowl.

It will be further evident that the construction is such that machining of parts is unnecessary, said parts are all of such nature that they can be readily cast. Furthermore, there are no bolt holes to be drilled, all Jarts being so constructed that they can be assembled without the necessity of the employment of bolts or other fastenv ing device.
