HOG-PEN.

Application filed November 9, 1916.

To all whom it may concern."

Be it known that I, HENRY L. FnRRIs, a citizen of the United States, residing at Harvard, in the county of McHenry and State of Illinois, have invented a new and useful Improvement in Hog-Pens, of which the following is a specification.

Myinvention relates to certain new and useful improvements in hog-pens, and is fully described and explained in the specification and shown in the accompanying drawings, in which:

Figure 1 is an elevation of the improved pen; Fig. 2 is a section on the line 2 of Fig. 1, showing the guard swung back; Fig. 3 is a section on the line 3 of Fig. 1, showing the guard in normal position and the trough elevated; Fig. 4 is a section on the line 4 of Fig. '1; Fig. 5 is an elevation similar to Fig. 1 of a modified construction, and Fig. 6 is a section on the line 6 of Fig. 5.

Referring to the drawings, 7 is a curb, preferably of concrete, to which are secured in any appropriate manner posts 8 connecttatably mounted a rock-shaft 11.

. ends ed by a top rail 9 and having at their lower forwardly extending brackets 10 forming horizontalbearings in which 1s ro- Hung from the top rail .9 is a swinging guard comprising a top bar 12, bottom bar 13 and vertical tubes 14. The top and bottom bars 12 and 13 of the guard are preferably square in cross-section and the vertical bars of the guard are preferably passed through openings in the bottom and top faces of the top and bottom bars, respectively, to bear the guard.

against the opposite surfaces of saidbars and the whole guard being held together by bolts 15 passed through certaln of the vertical bars and through perforations in the top and bottom bars. This method of construction'is exceedingly simple and convenient, it permits quick assembling and produces at the minimum cost a very r gid guard structure.

The rock-shaft 11 has secured to its arms 16, bifurcated at their upper ends to re ceive pivotally, in holes in their furcations, gudgeons 16 on collars 1 7 vertically slidable upon certain of the vertical bars of The furcations of the arms 16 also receive pivotally between them the lower end of a pull rod 18 having at its upper end a handle 19 and a guide-ring 20 which surrounds the corresponding vertical Specification of Letters Patent.

bar of the guard. In the structure herein illustrated two arms 16 with their connections are'inounted upon the rock-shaft 11. They both necessarily move together, and are employed in the duplicate relation to secure even application of force at both ends of a comparatively long guard.

The guard is normally held in its outward or closed position by a hook 21 which engages the rock-shaft, as shown in Fig. 4, and which can be pulled up to release the guard by means of a button 22 running in a slot in the upper end of one of the Vertical bars of the guard and connected by a rod or wire with the hook 21.

23 is a feed trough which is made of metal and is pivoted to brackets 24 secured to the curb so that it can be swung from its lowered position, as shown in F ig. 2, to the elevated position, shown in Fig. 3. When in use it occupies the lowered position and it is swung up to dump most of its contents, and to take a position where it can readily be washed out. The trough is held in its upper position by a hook 25 pivoted to a bracket 26 on one of the vertical bars of the guard. The hook has an upward extension formed into an oval ring 27 surrounding the vertical bar of the guard and permitting the requisite play to the hook, while at the same time furnishing a very secure support for the hook upon the bar;

The operation of the preferred device so far explained is relatively simple. It is found in practice difficult to handle hogs while the trough is being filled, not only because the trough is normally inside of the pen and inaccessible, but because the hogs crowd and push into the trough while it is being filled. The pivoted guard here shown obviates this difficulty. Before feeding the hogs the trough is pushed down into its normal or lowered position, the button 22 is operated to raise the hook 21 and free the guard and the guard is then swung into the position shown in Fig. 2 over the trough, so as not only to keep the hogsfrom the trough, but to make the trough readily accessible from without the Jen. As the 'uard swin s b O dead center and, of course, lock the guard firmly in its inner position. Thetrough is then filled and the guard swung back by pulling up on the handle 1;) which raises -inby the foot of'the operator. In the former case, the button by which the locking hook 21 is controlled is within easy reach of the operator who is at the same time holding the handle 19.

. out as hereinbef-ore indicated.

The preferred form of construction having the rock-shaft and the duplicate bracearms 16 is the more desirable where the pen is a large one and the guard is therefore of considerable length. The pressure which a hog exerts against the guard in trying to get at'the food in the trough may be very heavy andiwi th a long guard it is important that it be braced inward at two points near the ends so that a twisting force can not be set upon it. When 2111361118 smaller, however, and 'a shorter guard can be used, the balanced bracing is of less importance and the simpler structure of the modified form can be adopted.

Referring now to Fig. 5 the construction is precisely the same as that shown in the other figures, except that there is onlya single arm 16, this being pivotally mounted upon a central bracket 28 on the curb. The operating-handle for the brace 16 is omitted in this form of construction and the guard is locked in its normal position by a hook 29 pivoted to its bottom bar and engaging a laterally extending pin 30 on the arm '16 and extending 'sufiiciently forward therefrom that it can be operated by thefoot. This structure is operated, in general, the same way asthe preferred structure but with this difference.

1 The guard is released by raising the hook 529, commonly by the-toe of the operator and the guard is then pressed in either by hand or by the foot of the operator resting on its bottom bar or on the arm 16. \Vhen it is desiredto return the guard to normal posi' tion the arm is simply swung up either by the toe of the operator or'by hand and the guard swings shut principally bygravity.

I realize that considerable variation is possible in the details of this construction without departing from the spirit of my in vention; therefore I do not intend to limit myself to the specific form herein shown and *described B P Pointed out the 01 state of the art.
