To all whom, it may concern:

Be it known that I, CARL SOHWEND, a citizen of the Kingdom of WViirtemberg, and oftheEmpire of Germany,a subject of the King of W iirtemberg, and a resident of, the city of Mulheim-on-the-Rhine, in the Kingdom of Prussia and Empire of Germany, have invented a new and useful Improvement in Trellises, (for which I have obtained Letters Patent in Engcheap in construction, most hop'growers nevertheless fall back upon the pole-plantations, or retain the same. The reason for this, seemingly, is that the wire arrangements hitherto made were of faulty construction and consequently could not resist storms. The main fault of all these constructions is that thehorizontal wires are drawn tight, and consequently have to bear tensile strain and at the same time have to support the weight of the hop plants. Now, if lateral wind-pressure is also to be borne, it is clear that the wires must break, as because of difficulties in mounting, and because of cost they cannot be made so heavy as to resist these combined influences,

and as a tight wire cannot be expected to carry weight. The arrangement of a wire espalier or trellis for hop plantations shown in the annexed drawings presents a principle entirely different from the hitherto customary ones and characterized by the employment ofa specialsystem of storm-wires, which is totally independent from the carrying wires and those for the plants to climb upon, and has to bear no further load ,and which, when a storm occurs,holds the whole structure together. The carrying or supporting wires also constitute an independent system and-are not tightly stretched, so that as the growth of the plants progresses they form a pendent curve, imparting to the same concreasing temperature, and this for the reason that the posts are capable, within certain limits, of following the storm-wires.

In order that my invention may be fully un derstood, I will proceed to describe it with reference to the accompanying drawings, in which Figure 1 is a plan view of my improved espalier or trellis for use on a hill-side. Fig. 2 is a vertical section of the same, as seen from the right. Fig. 3 is a side elevation thereof as seen from the left. Fig. 4 is a front View at the broadest part of the garden. Fig. 5 is a top View of a standard head-piece. Fig. 6 is a side elevation of the same. Fig. 7 isa side elevation at right angles to that shown in Fig. 6. Fig. 8 is a side elevation of a modified form of head-piece. Fig. 9 is a vertical section of the same at right angles thereto. Fig. 10 is a top view of that shown in Fig. 8. Fig. 11 is a top View of another form of headpiece. Fig. 12 is a vertical section of the same.

Fig. 13 is a side elevation at right angles to that shown 'in Fig. 11. Fig. 14 is a vertical section of a stay head-piece. Fig. 15 is a top view of the same at right angles to that shown in Fig. 14. Fig. 16 is a side elevation thereof. Fig. 17 is a side elevation of the hook for supporting thecross-wires onthesupporting-wires. Fig. 17 is a side elevation of the same at right angles to that shown in Fig. 17. Fig. 18 is a vertical section of the lower end of the standard and the upper end of the supporting block. Fig. 19 is a similar view showing a modification. Fig. is a view of the eyelet for connecting the anchoring-wire with the main wire and storm-wire.

A are the vertical posts or standards; 1) inclined stays or standards, both loosely connected to base S. E is the head-piece on the vertical standard. 15 is the head-piece of the inclined staysflV, the rising wires, (those for the plants to climb upon F, cross-wires carrying the latter; 0, the main supportingwires upon which the cross-wires are suspended, and b the stornrwires.

Figs. 5, 6, and 7 show head-pieces 1G for the standards for supporting the stornrwires and supporting-wires, the wires being held fast by means of clamping-pieces.

Figs. 8, 9, and 10, show head-pieces E (cast in metal) for the standards in which the stormwires and supporting-wires are only held in recesses narrowed toward the lower end, and merely by wedging or jamming.

Figs. 11, 12, and 13 show head-pieces E for the standards, in which the storm-wires and supporting-wires are held by clamping-jaws on the top,:capable of being tightened up by screws.

Figs. 14, 15, and 16 show headpieces F1 for the obliquepost or stays, over which the stormwires are led to their ground anchorage, and provided with clamping-jaws and tighteningscrews.

Hereby the insecure and troublesome knotting and tying of the wires upon the standard-heads is avoided. The wires pass through the whole length or breadth of the garden without knotting, and in a single piece, whereby the mounting is mnch facilitated and security against breaking increased.

The standards or posts A, Figs. 1, 2, 3, 4-, are raised, according to the plan of the garden, vertically and loosely upon stone foundations, at such distances from one another that one standard is allowed for about forty-nine plants or vines. The head-pieces E E E of these standards carry both stornrwires and supporting-wires. By thetightly-stretched stormwires the standards are rigidly connected with one another. To this end these may be provided with one of the fittings hereinafter described.

Figs. 5, 6, and 7 show the headpiece E of the standard, provided with grooves or recesses crossing one another at right angles upon their front ends, and aring, a, tightly wedged upon the same, so as to prevent splittin The storm-wires I) and supporting-wires c, which cross one another, lie in these recesses, and are secured by hooks d, driven in after the espalier is finished. To prevent change of position of the standard-head with relation to the storm-wires, and also to prevent alteration of the correct shape of the supportingwire 0, (the shape being that of a curve depending between the standard-hcads,) and to prevent all increase of tensile strain upon the supporting-wire by its load, (consequently upon the alteration of the shape of the depending curve,) the clamping-pieces e are jammed upon these wires. The clampingpieces are pushed tightly up to the ring a of the stamlard-hezul and drawn together by a screw.

As seen in Fig. 5 of the drawings,that stormwire which does not run parallel with the supporting-wire receives clamps of a less size than the storm-wire which runs parallel with the same. In the latter case clamps c are used, Figs. 6 and 7, which hold both the stormwire and the thicker supportingwire underneath it.

The standard head-piece E (shown in Figs. 8, t), and 10) is intended to be preferably made of malleable cast-iron or cast-steel, and forms a kind of hood, which is tightly driven upon the end of the standard.

a a 10" are cheek-pieces, which, arranged in pairs, form recesses between them. These recesses are narrower at their lower end than at the top, in which both the storm-wires and the supporting-wires are tightly pushed, and thus are held by friction only, which can be increased by corrugating or roughening the inner surfaces of the inner faces of these tapering recesses or clef ts. The transverse stormwire I) passes through the recess between the jaws to a, that which is parallel with the supporting-wires is in the recess of the jaws a a, while the supporting-wirec is jammed tightly into the recess of the jaws a a.

It must be observed that the supportingwire is not placed directly beneath the stormwire, but somewhat at the side of the same. This, however, does not affect the stability of the whole system, Figs. 8, 9, and 10.

A head-piece, E,also cast ofmetal and serving for the wire-post, is shown in Figs. 11, 12, and 13. The storm-wires b b, crossing one another and supporting the wire 0, are simultaneously p rcssed intoa small prismatic recess by a clamping-jaw, r The clamping'jawgis drawn tight by means of the screw h. The projections It on the head-piece are to prevent the turning of the standard A, and serve for the purpose of preventing the wires from slipping off the same before being drawn tight and wedged fast.

The inclined stays D over the head-pieces E, (likewise cast,) of which the storm-wires and supporting-wires pass, (see Figs. 14,15, and 16,) serve to hold the entire system up, and the storm-wires and supporting-wires are by a loop or eyelet, Fig. 20, connected with the anchor-wires b", which in turn are attached to an earth-anchor or foundation of masonry or the like. The storm'wire b, which extends directly downward, is not wedged fast upon the head, but is merely guided between two projections, 1' 1', Figs. lat, 15, and 16. The second storm-wire l), passing around the entire limits of the garden or plantation, is fastened to each of the inclined standards or stays D by a clamping-plate and a screw, 1.

In hop-gardens of the usual extent the ingarden only, as the storm-wires are anchored its base.

clined posts or stays D need be placed at suitable distances apart and upon the limits of the at those points only, while in large gardens this will be required within the planted garden also.

Instead of thesimple stretched steel or iron wires, which are herein termed the stormwires, plaited wire cord or thin wire rope may be used, as these, costing little more, are considered more durable.

The cross-wires F, to which the rising wires vV, Figs. 1, 2, 3,4, are attached, are hooked to the supporting-wires c by the hooks represented in Figs. 17 and 17, and in such amanher that they cannot shift. To this end this hook, of the shape of a somewhat distorted S, is so arranged that each of the bent ends forms a narrowing opening in which the wires wedge themselves tight, so that all lateral movement of the same is prevented. The security of this attachment increases with the weight and growth of the plant climbing upon the rising wire.

Both the vertical and the inclined stays or standards are at the bottom only loosely placed upon a stone base and engage in a recess of the base either by a pin, 00, driven into the lower end of the posts, as shown in Fig. 18, or by a projection, 00, as shown in Fig. 19, cast upon a cap which is tightly driven upon the post end. In either case the pin x or the projection 0c prevents the post from slipping off The said pin 00 or the projection 00 are, however, of less diameter than the recess in the stone base, so that the post is free to move within certain limits, and that, as has been hereinabove stated, the strains in the entire system may as far as can be equalized. Moreover, the rotting of the ends of the poles that have heretofore been buried in the ground to the depth of more than three feet is avoided.

The posts or standards may consist of iron piping fixed together, or of poles or the like.

In Figs. 18 and 19, S is the base or socket, of stone. It is obvious that the arrangement of these espaliers will have to be varied, according to requirements, both as to the placing of the vertical posts or stays, as also of the inclined stays placed-at the confines of the plot; but on the whole the principle of strictly separating the storm-wires or wire ropes, which sustain the standards from the supportingwires which carry the cross-wire to which the rising wires are attached, constitutesthe'leading features of my invention.

Having thus described my invention,what I claim, and desire to secure by Letters Patent, 1s

1. In an espalier or trellis, the combination of the standards, the tightly-stretched stormwires extending thereover, the cross-wires, the rising wires, and the main supporting-wires extending over the standards on which the cross-wires and rising wires are sustained independently of the storm-wires, substantially as described.
