Application filed June 17, 1921. Serial No. 478,292.

Enclosures, of which the following is a specification. 1

y invention relates to guard-rails to be applied to hog pensor hog houses and the like, to afford a zone of safety for little pigs, and to prevent the mother from crushing them against the walls'of the inclosure,

which is liable to happen unless there is some protection; and it consists of an improved constructionof the means for attaching-the guard-rails, whereby they may be easily and quickly placed in operative position and as easily and quickly be folded up out ofthe way when not needed. Also, of otherimproved features which will be set forth in the specification and claims.

In the accompanying drawings forming a part of this specification, Fig. l. is a perspective of a portion of a panel of a hog pen, showing a guard-rail attached and in operative position by means embodying my invention. Fig. Bis the same sl'iowing the guardrail folded up out of the way, a portion of one of the connections being broken away, as will be hereafter explained. Fig.

3 is an enlarged horizontal section on line 33 of Fig; 1. Fig. t is an enlarged trans verse section on line l-l of Fig. 1, looking in the direction of thearrow. Fig. 5 is a plan View showing the attachment of a section of the guard-rail on opposite sides oi? a partition in a hog-pen.

Referring to the drawings, A represents the floor, and B a portion of the curb of a hog pen. A portion of one of the panels of the pen is shown by a section of the lower rail G and by sections of the fillers D. A pair of quadrant shaped supporting members E are secured to two of the fillers D by means 'of bolts F passed through clips Cr and through the flanges on the ends of the members E. It is preferable that these supporting members should consist of two mat ing parts one of which is removed in one of the connections shown in Fig. .2.

Extension members H to which the guardrail I is attached by means of clamps J are pivoted in the outer upper ends of the supporting members E by means of bolts ii passed through thimbles T. Theopenings in the members H, in which the thimbles are inserted are made oblong, or in the form of a slot, as shown in Figs. 2 and 3,.whereby the members H will have a limited end movement in the supporting members E.

The members H are preferably made hollow with closed inner ends and with projecting fingers or lugs L on said inner ends, as shown in Figs. 2 and 3. The members E are made rights and lefts, and when placed on opposite sides of the members H there will be a space between them to permit the movement of the pivoted ends of the membersI-l. A spring is applied to each of the members H, preferably by inserting a compression coiled spring M, in the hollow of the member between its closed inner end and the thimbles T. These springs will push the inner ends of the members as far as the thiinbles in the oblong or slotted openings will permit.

The quadrant shaped portions of the members E have inwardly mating flanges N on most of their lower and inner edges, butat their extreme upper and lower ends these flanges are cut away so as to form notched recesses O and P. When the members H with the guard-rail attached are in the position shown in Fig.1, the lugs L will be forced into the notched recess 0 by the pressure of the springs M, and will be held therein by the'tension of the springs. When in this position the guard-rail I will beheld within a few inches of the floor A, and the.

mother of the little pigs will be prevented by the rail from getting any closer to the curb B, while the little pigs can easily pass under the rail and cannot be crushed by their mother.

When the guard-rail is not needed it can be readily, turned up out of the way, as shown in Fig. .2, by taking hold of the rail and pulling it out to overcome the tension oi the springs, when the lugs L will be withdrawn from the notched recesses O and will rest on the flanges N. The members H can then turned on their pivots and the rail can be readily raised until it assumes the position shown in Fig. 2, when the springs will force the lugs L into the sary is to pull it up to overcome the tension ofthe springs when the lugs L will be withdrawn, from the notched recesses P, and the members H can be turned on the pivot bolts K until the lugs L will enter the notched recesses O, and the rail will be held in the position shown by Fig. 1.

To place a guardrail on each side of a partition in a hog-pen orhog house when a panel with fillers D is use-d, thelclipflG is taken off and a pair or supporting members E are placed on opposite-sides of the fillers, soxthe flanges through which the bolts F are passed will abut each other and the bolts will be passed through these flanges to secure the membersto the fillers, as shown by the plan view of Fig. 5. a

The guard-rail can be readily attached to the wall of a hog house by removing the clips G and passing bolts or screws through the holes in the flanges on the rear endsof the members E and into or through the wall. lo hold the members E more securely together lugs R are preferably formed on the lower edges through which a boltis passed. The arrangement is extremely simple and inexpensive, and is also effective in operation.

i .What I claim'is:

of supporting members adapted to be attached to the structure of the inclosure, said members having a pair of spaced apart notched recesses in their bodies; a pair of extension members pivoted in the supporting members so as to have end movement therein; and their inner ends being adapted to enter and to be withdrawn from said recesses; a guardrail secured to the outer ends of said extension members,'and a spring ap plied to each extension member to push it endwise, whereby the inner end of each member will be held in one or another of the notched recesses, until released therefrom by overcoming the tension of the springs and the guard rail will be rigidly held in either operative or folded position when the ends of the extension members are in one or the other of the recesses.

2. In guard-rails for pig inclosures, a pair of supporting members adapted'to be at tached to thestructure of the inclosure, said members consisting of a pair of mating eastings having a pair of spaced apart notched recesses between them; a pair of extension members pivoted between said castings so as to have end movement on'their pivots, and their inner pends adapted to enter and'to be withdrawn from said recesses; a guard-rail secured to the outer ends of the extension members, and a spring applied to each extension member to push it endwise, whereby the inner end of each member will be held in one or another of said notched recesses until released therefrom by overcoming the tension of the springs and the guard rail will-be rigidly held in either operative or folded position when the ends of the extension inen' bers are in one orthe other of the recesses.

3, In guard-rails for pig inclosures, a pair of supporting members adapted to be at tached to the structure of the inclosure, said members consisting of a pair of mating-castings having quadrant shaped edges and inwardly mating flanges on said edges with notched recesses at the upper and lower ends of the flanges; a pair of extension members pivoted between said castings so as to have end movement on their pivots, and their inner ends adapted to enter and tobeiwith drawn iromsaid recesses a a'guard rail-securedto the outer endsof the extension members, and a spring applied to each extension member to push it endwise, whereby the inner end of each member will be held in one or the other of said notched recesses until released therefromby overcoming the tension of the springs. I i

l. In guardrails for pig inclosures, a pair of supporting members adaptedto beat tached to the structure of the inclosure, said members consisting of a pair of mating castings having spaced apart notched recesses between them a pair of extension members pivoted between saidcastings so as to have pression coiled spring inserted in the hollow of each extension member, one end of the spring bearing against the pivot of the extension member and the other end of the spring bearing against the closed end of the member, whereby the lug on the inner end of each member will be held in tumor another of said notched recesses until'released therefrom by overcoming the tensionof the springs.

In a device of the character described, a guard-rail spaced a distance away from the inclosure in which it is installed; a pair of supporting members adapted to be attached to the structure of the inclosure and having spaced apart notched recesses in their bodies, each member having spaced apart portions; a pair of extension members havmg then outer ends aiiixed to the guardrail and a slotted opening in a central portion of each of the members, their bodies being hollow and their inner ends closed; a'thimble inserted in each of the slotted openings and placed between the spaced apart portions of the supporting members; a bolt passed through each of the thimbles and through corresponding holes in each of said spaced apart portions, the thimbles thereby forming pivots for the extension members, and a coiled compression spring inserted in the hollow of each extension member, one end of the spring bearing against the thimble and the other end against the closed end of the member, whereby the closed ends of the member will be held in one or another of said notched recesses until released therefrom by overcoming the tension of the springs, thereby rigidly holding the guardrail when in raised or lowered position.

6. In guard-rails for pig inclosures having partitions therein, a pair of supporting members, secured to each side of the partition by bolts connecting the abutting sets of the members together, said members having spaced apart notched recesses in their bodies; a pair of extension members pivoted in the supporting members on each side of the partition so as to have end movement therein, and their inner ends adapted to enter, and to be withdrawn from said notched recesses; a guard-rail secured to the outer ends of the extension members, and means applied to each extension to push it endwise, whereby the inner end of each extension member will be held in one or another of the notched recesses until released therefrom by pulling the members endwise away from said recesses.
