GATE.

Specification of Letters Patent.

Patented May 23, 1911.

Application filed October 5, 1910. Serial No. 585,485.

To all whom it may concern:

Be it known that I, HARRY Gr. SoHnNoK, a citizen of the United States, residing at Delphi, in the county of Carroll and State of Indiana, have invented a new and useful Gate, of which the following is a specification.

It is the object of the present invention to provide an improved construction of gate of that type adapted to be swung about a vertical axis from open to closed pos1t1on and vice versa and adapted to be, swung up to a limited degree at its free end whereby to permit of the passage thereunder of small stock.

One aim of the invention is to provide an improved means for holding the gate at various points in its vertical swinglng movement.

Another aim of the invention is to provide improved means for limiting the vertical swinging movement of the gate both in an upward and in a downward direction.

A further aim of the invention is to provide novel means for holding the gate against upward swinging movement so as to prevent the passage thereunder of small stock, when the gate is in lowered position.

With the above and other objects in view, the invention resides in the general construction and arrangement of parts substantially as shown in the accompanying drawings, in which,

Figure 1 is a view in side elevation of the gate embodying the present invention, the gate being shown closed and lowered. Fig. 2 is a view similar to Fig. 1 but showing the gate closed and swung up to permit of the passage therebeneath of small stock. Fig. 3 is a top plan view of the gate. Fig. 4 is a vertical sectional view in detail on the line 44 of Fig. 1. Fig. 5 is a detail view partly in elevation and partly in section of the means employed for holding the gate at various points in its vertical swinging movement.

In the drawings, there is shown a post 10 upon which the gate is hingedly supported, and a post 11 which is the keeper post for the gate. The gate itself is illustrated as embodying, in its structure, a pair of end stiles 12, a pair of end stiles 13, a-

pair of intermediate stiles 14, and bars 15, these bars extending between the stiles 12 and 13 and being pivoted as at 16, 17, and 18, between the Stiles 12, 13, and 14 respectively. Hinges for the gate are indicated by the numeral 19 and are secured to the stiles 12 and have pivotal connection with the post 10 as at 20. It will at this point be readily understood that all of the bars 15 may swing vertically upon the pivots 16 and that the stiles 13 and 14 will be carried vertically with the bars and will maintain parallel relation at all times. Pivoted at their lower ends to the lower one of the hinges 19, is a pair of bars 21, one bar eX- tending to each side of the bars 15 of the gate. At their upper ends, these bars pivotally connect as at 22 to a rocker 23 which is pivoted as at 24 between the upper ends of the stiles 14 of the gate. To the other end of the rocker 23, or more specifically at that end located near the free end of the gate, there are pivoted the upper ends of a pair of bars 25 corresponding to the bars 21, and the bars 25 are pivoted at their lower ends as at 26 to the ends of the lowermost bar 15 of the gate.

Between the bars 21 and between the bars 25, there are secured stop blocks indicated by the numerals 27 and 28 respectively. Each of the stop blocks lies between a pair of the bars 15 and as will be observed from an inspection of Fig. 1 of the drawings, when the gate is in lowered position, the blocks abut against the under edges of the bars 15 whereas the blocks 28 bear against the upper edges of the said bars, the gate being, by reason of this engagement, held against downward movement beyond the position shown in the said Fig. 1. By referring to Fig. 2 of the drawings, however, it will be observed that when the gate is swung up to the position which it assumes in this figure, the blocks 27 will abut against the upper edges of the bars 15 and the blocks 28 will in a like manner abut against the under edges of the said bars, further movement of the gate in an upward direction in this manner being prevented. It will be observed that not only do these blocks 27 and 28 perform the function above described, but they also materially strengthen the gate structure as a whole.

By comparing Figs. 1 and 2 of the drawings, it will be seen that normally that end of the rocker 23 to which the bars 25 are connected is lower than the end to which the bars 21 are connected. However, as the free end of the gate is swung upwardly, and as sumes the position shown in Fig. 2, or substantially this position, the first mentioned end of the rocker swings upwardly and the last mentioned end swings downwardly. The weight of the gate naturally exerts a tendency to return the parts to the position shown in Fig. 1 and therefore there is a tendency for the right hand end of the rocker in Fig. 2 of the drawings to swing up when the gate is in the position shown in Fig. 2. Advantage is taken of this tendency of the rocker to return to the position shown in Fig. 1' of the drawings. in providing means for holding the gate at various points in its vertical swinging movement and this means is preferably embodied in an arcuate rack bar 29 which is pivotally suspended as at 30 from the right hand end of the rocker 23. The convex edge of the rack bar is the edge which is of rack formation, the teeth being indicated by the numeral 31. The bar works loosely through a guide 32 upon the uppermost one of the bars 15 and through a guide 33 secured upon one of the intermediate stiles 14 and constituting a part of a keeper member for the said bar. This keeper member includes a tooth 3 1 with which the teeth 31 of the rack bar may have engagement interchangeably. It will be observed that as the outer end of the gate is swung upwardly, the rack bar will slide freely through the keeper 33, the teeth 31 of the rack bar riding over the teeth 34 of the keeper. WVhen the gate has been elevated at its free end to the desired degree, it is released and one of the teeth 31 will engage with the teeth 34 and the gate will be held in the position to which it has been adjusted. When it is desired to lower the gate the lower or free end of the rack bar is grasped and the gate slightly lifted whereupon the rack bar may be readily lifted and held out of engagement with the tooth 3 1 to permit of lowering of the gate.

Upon the post 11 there is secured a keeper indicated by the numeral 35 and a latch 36 and a latch 37 are slidably mounted upon certain of the bars 15. When the gate is in lowered position as illustrated in Fig. 1 of the drawings, the said latch 36 is slid upon the bar 15 upon which it is supported, with its free end engaging with the keeper 35. Then the gate is to be swung up to the position shown in Fig. 2 of the drawings, the latch 36 is drawn back and after the gate has been properly adjusted, the latch 37 is slid outwardly into engagement with the keeper.

As a means for preventing the upward swinging movement of the gate when it is not desired to have small stock pass there beneath, and the gate is in closed position, there is slidably mounted upon one bar 15 of the ate, a wedge member 38 which may be slid lnto position between the upper edge of the bar upon which it rests, and the under side of the respectiveblock 27.

What is claimed is In a gate of the class described, end stiles, bars extending between and pivoted at their ends to the stiles, an intermediate stile, a rocker pivoted thereon, bars pivoted at the lower ends of the end stiles and to the ends of the rocker, a rack carried by the rocker, a fixed keeper for the rack, a block secured between a pair of the last mentioned bars, and means for holding the first mentioned bars against vertical swinging movement, said means comprising a wedge member slidable upon one of the first mentioned bars and movable to position between the upper edge thereof and the underside of the said block.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
