COLLAPSIBLE GATE.

Specication of Letters Patent.

Patented Nov. 21, 1911.

Application led February 23, 1910. Serial No. 545,379.

To all whom t may concern.'

Be it known that I, RICHARD EDWIN RAX- woRrHY, a subject of the King of England, residing at 17 Matham Grove, East Dulwich, in England, have invented certain new and useful Improvements in Collapsible Gates, of which the following is a specification.

This invention relates to improvements in collapsible gates of the type generally known as lattice gates. These gates consist broadly of two sets of lat-tice bars, one set of bars crossing the other set and the vertical pickets having pivots connecting the pickets with the lattice bars at the point of crossing of the bars.

According to this invention in addition to the customary pickets, intermediate picket-like members are employed but the arrangement is such that when the gate is contracted, that is to say, when all the pickets are close together, the intermediate picket-like members will not take up any eXtra room, but will allow the gate to fold up in the same width as it would do if the intermediate members were not present.

This invention will now be described with reference to the accomuna -..g drawings, in which:-

Figure 1 shows one construction of gate in its extended position and partlv broken away. Fig. 2 illustrates the gate in its contracted position, Fig. 3 is a view of a modilied construction of gate extended and partly broken away. Fig. 4 shows a modification in the intermediate picket-like' members. Fig. 5 is a sectional detail on the line 1*-1 of Fig. 1, Fig. 6 is a sectional detail o-n the line 2 2 of Fig. 1, Fig. 7 is a sectional detail on the line 3 3 of Fig. 1, Fig. 8 is a sectional detail on the line 4-4 of Fig. 1, Fig. 9 is a sectional detail on the line 5--5 of Fig. 1, Fig. 10 is a sectional view of a modified construction of picket and its connection to the lattice bars and Fig. 11 is a further modification of picket. Figs. 5-11 are drawn to a larger scale than Figs. 1-4.

Two sets of pickets A and A1 are arranged in the customary manner to slide in guides B, B1, one set of pickets A being on one side of the guide bar, and the other set of pickets A1 being on the other side there of, the members of the two sets registering with each other. On the inner side of the pickets A and pivotally secured thereto as at D, is a set of lattice bars C as sho-wn more particularly in Figs. 7, 8 and 9. The pivots are not each denoted by reference letters in Figs. 1, 2, 3 and 4, but are denoted by way of example. Pivoted as at D1 to the other side of the pickets A1 is a second set of lattice bars O1. The oivots D however, only connect the pickets A and the lattice bars C, while the pivots D1 only connect the pickets A1 and the lattice bars C1. The lattice bars C are arranged so that they cross the lattice bars C1 in the well-known and customary manner in gates of this construction. Intermediate members E are pivoted to the lattice bars C, U1 at the points of crossing of the bars as illustrated at F1 in Figs. 5 and 6. The intermediate members E are parallel to the pickets A or A1. They do not however, extend to the guides B or B1.

In the construction illustrated in Fig. 1, the gate is comprised of two complete and separate lattice constructions, one of which is pivoted by the stationary pivots G, and the other by the stationary pivots G1 to the pickets. The pivots Gr and G1 do no-t pass through both the sets of lattice bars but are arranged in the manner described with reference to Figs. 7, 8 or 9. The pickets are slotted as at H or H1 to allow the meeting ends of the lattice bars to move in the vertical direction. The intermediate bars E also have slots F formed in them for the same purpose. The pivots referred to in Fig. 1 as Gr and G1 are equivalent to the pivots D of Fig. 7.

Figs. 10 and 11 show in section the modilied forms of pickets with lattice bars pivot ed thereto. In Fig. 10 pickets A and A1 are shown as slotted bars and the bolts D and D1 have enlarged heads which work in the slots. In Fig. 11 the pickets A and A1 are shown as channel bars and the pivots in this case also have enlarged heads which work in the channels. The elevation of a gate constructed in either of these forms is shown in Fig. 3. w

In Fig. 4 the pickets are shown as having bolts J connecting each picket of one set with the picket of the other set which regis ters with it. The bolts J are situated in the pickets midway between two sets of lattice structures. The intermediate bars E are deformed at a position opposed to the bolts J, and in the particular construction illustrated, the intermediate members are given a twist.

When the gate, as illustrated in either Figs. l, 3 or 4L is contracted as shown in Fig. 2, the intermediate members slide in between the pivots D or D1 as illustrated in Figs. 7, 8 or 9. Thus, although eXtra picket-like members have been provided, the gate con'- tracts into the same width as it would do, had the intermediate members not been present. Thus, the advantage of having extra bars or members in the formation of a gate lis also combined with the advantage of allowing the gate to contract into the width not larger than heretofore. It is Aobvious that, with the construction described with reference to F ig. t as the intermediate members are deformed at the points opposed to the transverse bolts J, it will still be possible for the intermediate members to pass in between the pivots D and D1.

Vhat I claim as my invention and desire to secure by Letters Patent is l. In a collapsible lattice gate, the combination with two sets of lattice bars, one set of bars crossing the other set, of two sets of pickets, one set pivoted to the outer sides of one set of lattice bars and the other set pivoted to the outer sides of the second set of lattice bars, thereby leaving an unobstructed space between adjacent picket bars, of the two sets, and a set of intermediate picketlike members pivoted between the two sets of lattice bars at the point of crossing of said lattice bars, whereby when the gate is collapsed the intermediate picket members may lide between the main pickets and lattice ars.

2. In a collapsible lattice gate the combination of two sets of lattice bars, one set of bars crossing the other set, a set of pickets pivoted to the outer sides of one set of bars, another set of pickets pivoted independently of the first set of pickets to the outer sides of the second set of bars, the members of one set of pickets registering with those of the other set and a set of intermediate picketlike members pivoted betweenthe two sets of lattice bars at the point of crossing of one set over the other.

3. In a collapsible lattice gate the combination of two sets of pickets, the members of one set registering with those of the other set, transverse bolts connecting pairs of opposing picket members, a set of lattice bars pivoted to the inner sides of one set of pickets, another set of lattice bars crossing those of the rst s't and pivoted to the inner sides of the second set of pickets, the bars being pivoted to the outer sides of one set of bars,I

another set of pickets pivoted independently of the first set of pickets to the outer sides of the second set'of bars and a set of picketlike members pivoted between the two sets of lattice bars at the point of crossing of one set over the other, the lattice bars being slidingly pivoted to the pickets and intermediate bars.

5. In a collapsible lattice gate, the combination of two sets of lattice bars, one set of bars crossing the other set, a set of pickets pivoted to the outer sides of one set of bars, another set of pickets pivoted independently of the first set of pickets to the outer sides of the second set of bars, the members of one set of pickets registering with those of the other set and a set of intermediate picketlike members pivoted between the two sets of lattice bars at the point of crossing of one set over the other, the lattice bars being slidingly pivoted to the pickets and intermediate bars.

6. In a collapsible lattice gate, the combination of two sets of pickets, the members of one set registering with those of the other set, transverse bolts connecting pairs of opposing picket members, a set of lattice bars pivoted to the inner sides of one set of pickets, another set of lattice bars crossing those of the first set and pivoted to the inner sides of the second set of pickets, the bars being interrupted in the region of the transverse bolts, and a set of intermediate picket-like members pivoted between the two sets of lattice bars at the point of crossing of one set over the other and each deformed at a point opposed to the transverse bolts, the lattice bars being slidingly pivoted to the pickets and intermediate members.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
