HANS F. MAHLSTEDT, or GILMAN, IOWA HOG TROUGH Application filed April 7, 1928. Serial No. 268,202.

/ My invention relates to a trough to be used for feeding or watering animals, especially hogs, and has for its object to provide a trough of the type disclosed in the issued patent of Alfred J J ahde, #1,531,617, issued March 31, 1925. r

More specifically, it is my object to provide a trough of this type having means for securing it to a stationary support so as to prevent tipping and to simplify and cheapen the construction of such a trough without sacrificing durability or strength.

Another object of my invention is to provide atrough, the W ll of which may be made in three pieces, a reinforcing member being provided, adapted to permanently secure the three pieces together and adapted also to provide means for supporting the trough rigidly upon a stationary support. Thus the supporting members become an integral part of the trough and the construction of the trough is clearly simplified.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claim, and illustrated in the accompanying drawings, in

which Fig. 1 is a perspective view of the preferred form of my invention installed in connection with a stationary support.

' Fig. 2'is a plan view of the trough.

Fig. 3 is a transverse, sectional view, taken on the line 33 of Fig. 1.

Fig. 4: is a similar sectional view, showing 3 a somewhat modified form of my invention.

The two end walls 10 of the trough are substantially triangular shaped, as clearly illustrated in the drawings, with their rear edges vertical, as at 11, and their forward ends inclined inwardly and outwardly, as

' at 12. The upper edges of the end walls 10 are. rolled outwardly and around the side arms 13 of the longitudinal yoke, which is a U shaped member formed of a piece of heavy steel wire, joined with the'three portions 13 5G and 1% at right angles to each other.

A single, rectangular sheet of material is employed to form the front and rear walls 15 and 16, respectively, which are connected by a curved 'bottom. The rear wall 16 is vertical and the front wall 15 is inclined at the proper angle to correspond to the forward edges 12 of the end walls 10. The upper edge of the forward wall 15 is rolled outwardly around the member 14: of the reinforcing yoke and the upper edge of the rear wall 16 is rolled around a cross member 17, which is formed of wire and secured at its end tothe arms 13 of the yoke. As shown in the drawings, the preferable method of securing is by looping the ends of the cross member 16 about the side arms of the yoke.

The edges of the end walls 10 and the walls 15 and 16 are joined together by any I method such as by folding, crimping, soldering or welding. Almost any water-tight joint will be sufficient for the reason that the strains to which the trough will be subjected are borne by the wire reinforcing members almost entirely. Since a hog trough receives very rough usage, this is an essential feature of my invention.

One of the requirements for a hog trough is that'it shall be secured so that it cannot be tipped over by the hog. The hog, in rooting with his snout, is capable of exerting considerable pressure.

In order to'attain maximum strength, I form the elements by means of which the trough is secured to. a stationary support, as integral continuations of the reinforcing yoke. The side arms 13 are extended beyond the cross brace 17, as at 18 and in the preferred form of my invention are bent downwardly to form hooks 19, adapted to be received in vertical openings 20 in a sta tionary support 21, such as a horizontal rail of a fence or a portion of a gate or a hog house or the like. The hook 19 is made parallel to the rear wall 16 so that the wall 16 may abut flatly against the member 21. In this way, should the hog put its feet into the trough and allow its weight to rest in the trough, the pressure will be borne partly by the hook 19, partly by the extended arms 18 and partly by the rear wall 16.

Upward pressure of the snout of the hog against the trough will be borne entirely by the hook 19.

In the modified form of my invention, shown in Fig.4, the arms l8a'areiniade long enoughto extend clear thrloughthe sta'tion-, f ary support 21a and at their endsare curled to form rings 22, through which pins 23 are inserted to engage the rear face-ofi-'the*stationary members 21a. Upward pressure in,

this'case is borne by the arms 18a, engaged" against the upper limit oil-the. slot 28 in the support 21a. The slot 23" ismade large enough to: allow entrance ofthe'rin-gs 22.

. No matter where-:the-hogmay applypressure to the trough, this pressure Will 7 be transmitted directly to the reinforcing yoke forminganintegral-part of the trough and hence to the integral arms of the. yoke: There' will be lie-possibilityof:looser-ringv the joints at the cornersof; thetrough or looseniang the conneotionof-f the supporting-arms with the: trough; At the;sametime the constructionis simplified and eheapened: The wallsmaybe first-secured to the-yoke and thensol-dered together;,'the yoke acting to retain them i-n' their proper: relationshipi The necessity;- of f'nimlyfsecuring the supporting; arms" to the trough is, eliminated;
