AUTOMATIC SPRAYING DEVICE FOR STOCK."

Specification of Letters Patent.

Application led January 18.` 1907. Serial No. 352,881.

To alt whom it may con-cern: i v

Be it known that l, HnNDnRsoN Hormo- WELL, a citizen ofthe United States, residing in 1Whitewater township, Franklin county, indiana, have invented certain new and useful Improvements in Automatic Spraying Devices for Stock, of which the following is a specification.

My invention relates to spraying devices 'for stock, Vsuch as hogs, sheep or the like', so arranged that the stock may automatically operate the sprayer for causing `a spray of disinfectant, insecticide or the like, to play upon therstock.

It is the object of my invention to provide a new and improved automatic sprayer adapted to be operated by the stock when passingthereunder in one direction, but to remain inoperative when the stock passes thereunder in the opposite direction', and my invention consists in instrumentalities em'- ployed for said purpose, and in the parts,

and in vthe construction, arrangement and combinations of parts hereinafter more fully described and claimed.

In the drawings: Figure 1 is a front eleva-l i tion of'my improved device.v Fig. 2 is a `side elevationl of the same, showing the swinging gate in dotted lines in assumed position, as indicated at a, for operating the spray, and also showing the lower section of the gate in assumed position in dotted lines, as indicated at b, lindicating how this lower section may be swung without aecting the spray. Fig. 3 is a side elevation of my improved device with its, supporting posts broken awayand showing the gate swung into andretaine'd in irl-operative position. Fig. 4 is a plan view, partly broken away, showing the means for attaching the apparatus to posts of an inclosure, the pump being removed.,V Fig. 5 is a detail in perspective showing the slotted valve-arm.

Fig.. '6 is a separated view in perspective of the connecting link between the valve-arm and gate. Fig. 7 is-ancross-section of the valve and spraying nozzle taken on the liney Fig. 8 is a vcross-section on the :t of Fig. 1`. line yfy of Fig.` 1 sliowingthe means for adjustingthe gate toheight; and, Fig. 9 is an enlarged 'view oi the valve-mechanism.

1 1 lrepresent the gate-posts of an inclosure, at the upper end of which posts there -is a board 2.

3 is a swinging gate pivoted on a rod 1, supported at thelower ends of dependingbars 5. The bars 5 arejattached to a board 6 by -bolts 47. Cleats 8 are secured at the back of the board 6. Near each end 'of the board 6 a bolt 9 passes throgh one of a seriesof (apertures .10 in said board and one of the cleats, and through anyone oiv a series of apertures 11 inV the-board 2. The height of the lower end of the swinging gate above the ground is determined by selecting the apertures i and 11 through which the boltsshall pass, hereby adjusting the frate to height for ammodating dii'lerent classes of stock.

The gate 3- comprises a primary gate 12 and a sul:A 'ate 13 suspendedtherefrom. The

subgate swings upon the primary gate on a rod 14, the rod passing through bearings 15 at the bottoms of side bars 16 of the primary gate and through bearings 17 of the subgate, Vnuts 18 19 beingl threaded to each end of the rod'for positioning the parts laterally. subgate comprises preferably a metal bar of approximate U-shape. 'This bar is provided at its bottom with a recess 2O to which the stock will naturally go in passing the gate, thereby directing the stock under the spray. The upper 'end of the subgate is provided with lugs 21 yextending laterally across the front of the side-bars 16 so that when stock is passing said gate in the direction of the arrow c (Fig. 2), the subgatewill carry the primary gate With it When the stock makes contact with the subgate and moves the same .while passing thereunder. Il however the stock passes said gate from the opposite direction, the subgate willswing upon the rod 14 Without operating the lprimary gate and therefore not operatingthe spray'.

The upper end of -the primary gate is formed of an inverted U-shapedheavy-bal- 'anceiece 22, the bar 4 passing through aper` tures in the legs 23 of said piece 22 for forming the pivot for the' gate, the said apertures being adjacent the lower ends of saidlegs. The side-bars 16 are secured' to said balance-piece ,by bolts 24, a strengthening,connecting-bar 25 connecting the side-bars intermediately of their ends. l Theweight of the vbalancepiece 22, which is preferably a castirig,is so proportioned withrelation to the' weightoi the gate and the pivotof the gate, that the gate will normally hang in upright position,

the weight ofthe castingrhowever acting as a balance upon the lower end of ther gate for A stance is in liquid form. and may 4'iiow or be sprayed upon the stock by gravity, or 'if desired the spraying may be accomplished under pressure. pressure, I prefer to provide a pressure pump 27 which connects with the upper endof the tank by a pipe 28, a check valve 29 being located in the pipe which may' also have a stop-valve 30 therein. The pump is preferably mounted on the board 6 from which the gate is suspended so as to be adjusted with the gate and container. The container is secured to the board 6 by a bracket 31.

32 is a plug for closing the` receiving opening of the tank.

33 is a nozzlewhich, may be of suitable form forcomminuting the liquid to suitable extent. lIf the liquid is ejected un der pressure, I prefer to havean adjustable leaf 34 at thenozzle 'for breaking `the streamwhich may be ejected from the opening 35'into a spray, theadjustable leaf being clamped in place by a thumb-nut 34a.

36 is a valve, to the plug 3.7 ofy which a stem- 38 is secured. A valve-arm 39 is. secured in suitable relationto the stem by 'a bolt 40. A

' ar-m has a bearing 45 at its lower end inwhicli The valve-arm A link 47 is the 'valve-stem oscillate's. 39 is provided with a slot 46.

articulated with the valve-arm by a bolt 48- passing through one4 of a series of apertures 49 in the link and said slot 46. The swinging end of the valve-arml is preferably flat and the link 47 has a flat bifurcated end 50 for receiving said swinging end. The link at its other end has a hook 5.1 which contacts the rear face of the connecting web 52 of the balance-piece 2 2. The valve-arm, link and hook, in the form shown, forma connection and catch 'therefor operat-ively'disposed between the valve and balance-piece 22. When the connecting web swings forward it moves the link and-operates. the spray, the backward movement of. the connecting web 4however permitting the spray to remain inoperative. v f

53 is a'stop-arm v bearing arm 44 byy a bolt 54, the stop-arm having a lug 55 projecting yacross the path of the valve-arm 39, against which lug the' valve-arm is normally pressed by the spring 41. The valve has a passa e 56 therethrough communicating with t e nozzle 33.

If -accomplished under adjustably secured to the 'llhe valve-plug has a passage 57 therethrough.

When the valve is closed, the passage 57 is at right angles to the passage 56, the body ofv the valve-plug closing said. passage 56. Some rotation .of the valve-plug will be required prior to the registering of said passages. If now it is desiredto more quickly initiate the opening of said valve upon contact of the gate by stock, the stop-arm 53 is swung upon its bolt for depressing the lug 55 so that the valve-arm will be sooner arrested in its return to normal position, the normal position being the closed position of the valve. The bolt.48 is also inserted into an aperture nearer the hook-end of the link, corresponding with the new position of the valve-arm, so that the hook of the link may contact the rear face of ,the upper end of the gate when the latter is in upright position. p When now the lower end of the gate is contacted by stockpassing in the direction ofthe arrow c the spraying will be sooner initiated than if a greater swing were permitted the vvalve-arm. If on the -contraryit is desired to delay the spraying,

the stop-arm 53 ispositioned for permitting a full closure of the. vvalvev and the bolt 48 may also be inserted into one of the apertures 49 nearer the rear end ofthe hook-arm so that when the gate is swung the shank of fthe bolt may firstslide in the slot 46, the movement of the nozzle-'valve being initiated when said bolt reaches the end of said slot, the stock ,in Vthe meantime partially' swinging said .gate for' passing under the nozzle. I

lf it is desired' to temporarily throw the gate out of commission it may be swung upon the rod 4 until the subgate is raised a ove the pivot of-the primary gate, the

As'ubgate being retained in raised position as by a hook 58 on vthe pump. The gate is made of rods and bars so as to be open to permit the spray or flow of fluid to readily reach the animal.

Having thus fully described my invention what I claim as new and desire to secure by 4Letters Patent is:
