JOHN B. can, or MORTON, ILLINOIS, AssIGNOR TO INTERLOCKING FENCE do, or" MORTON, ILLINOIS, A CORPORATION or ILLINOIS GATE HIIVGE Application filed September 20,- 1930. Serial No. 483,159;

This invention has reference to certain new and useful improvements in gate hinges and it has for its principal object a hinge, which in addition to providing an eflicient support for the gate, permits the gate to swing back full 180 and in either direction, that is, flat back in parallel relation with the fence on either side thereof.

The invention has for a further object to provide such a hinge, including meshing segment gears, one each fixed to the end post of the fence and to an end bar of the gate frame, the same encased in a housing providing a bearing and complementary to said post and end bar and capable of pivotal movement about the end post, as the gate is swung around in either direction.

Other and further objects will more fully appear from the following description.

That the invention may be more fully undestood, reference is had to the accompanying drawing forming part of this description, illustrating a preferred embodiment of the invention, in which Fig. 1 is an elevation showing in part a fence and in part a gate, the latter being hung by a hinge embodying my invention;

Fig. 2 is a detail in plan and in section showing the construction of the hinge and as the same would appear if taken on the line 2-2 of Fig. 1, dotted lines showing a swung position of the gate;

Fig. 3 is a detail in elevation, partly in section and partly broken away as the same would appear on the line 3-3, Fig. 2, and

Fig. 4 is a diagrammatic plan showing a gate in a normally closed position, in full lines, and in dotted lines, the gate swung back in parallel relation on either side of the fence, made possible by the improved hinge by which the gate is hung.

Like characters of reference denote corresponding parts throughout the figures.

In the drawing, a fence A is shown supported by an end post B and a gate C having the usual frame and end bar D hinged to the end post B by my improved hinge. These elements of fence and gate are conventional showings and in no wise limiting, as the application of the hinge is not limited to any particular form or type of gate or fence, nor to the peculiar shape of post or end bar.

The hinges, and this applies toboth the upper and lower hinges, are substantially alike, as the invention'of the hinge makes it possible toemploy like structures in both the upper andlower hinges and in this respect this is a distinct advantage from the point of view of manufacture and assembly of the hinge. Therefore, the description of '6?) one such hinge will suffice for both.

The hinge comprises a segment gear- 1 secured tothe end post B and a segment gear 52 secured. to the end bar D of the gate frame,

which is shown meshing with the gear 1 and '65 adapted to ride on said gear 1 when the gate 1s swung in either direction and will permit the gate to'be swung back full 180 and in e ther direction, that is, flat back in parallel relation with the fence on either side thereof, 76 the closed position of the'hinge being shown in full lines in Fig. 2 and one such open position being indicated by the dotted lines, also in Fig. '2.

The preferred construction of the gear seg- 7 ment 1 includes the halfring sections 3 and 4, respectively, which are secured about and to the post B, see Fig. 3, the latter section being formed or provided with gear teeth, as shown. The preferred construction of the gear segment 2 is a ring-like member 5 provided with gear teeth, as shown, and having a hub portion 6 by means of which the member is secured -0n the end bar D. These gears are encased in a housing 7 which comprises the corresponding half sections 8 bolted together I and having portions complementary to the end post B and end bar D, respectively, and provide a bearing which is rotatable on the end post B when the gate is swung about said end post. This housing not only encases the gear sections-but provides a closure against ice and snow and is a'safety means against anything getting caught in and clogging the gears. Furthermore, the construction of the hinge reduces friction to a minimum since the movable parts move in the same direction around a given radius; alsothe design of structure is effective in keeping the gate in alignment and the action of the hinge with one gear rolling on the other has an effect like a ball bearing and weight on the free end of the gate has no efiect in any manner which would tend to cramp the hinge elements. Furthermore, it is pointed out, that the housings provide the coupling for connecting the gate to the support and with the housings having a pivotal connection with such support and the gearing, as constructed will permit the gate to have a pivotal relation with the housings whereby when the gears 2 roll around the gears 1 the speed of movement of the gate is in excess of the movement of the housings and thereby the swinging movement of the gate is not only facilitated but the gate also may be swung full 180,ineither direction.

\Vhat I claim is:

In a gate hinge, in combination, a segment gear arranged for securement to a i ence post, a segment gear meshing with said first mentioned gear and arranged for securement to a gate member, and a housing for said gear elements arranged to embrace said fence post and gate member and having pivotal movement about said fence post and gate member, when the gate is swung, the speed of pivotal movement of the gate when swung being in excess or" the speed of pivotal movement of said housing.

In witness whereof, I have hereunto set my hand, this 15 day of September, 1930;

' JOHN B. GETZ,
