Hennepin County, Minn. Y Application January 1s, 195s, serial No. 331,450- 1 claim. (cl. 47-s3) My invention relates to improvements in terrace barriers or curbingsV particularly, though not exclusively, for .A
bolstering up and retaining in place the soil in a terrace garden in a single tier, or in multiple superimposed tiers of pyrami'dal form.
An object of the invention is to provide a durable and inexpensive structure of the present nature consisting of sections of sheet metal in strips joined together end to end and constituting a barrier band which is adapted to stand on edge and which is capable of ready lateral flexure enabling the same to be conveniently laid on a line of chosen pattern.
. Another object of the invention is to provide a number of such bands or barrier :elements arcuated and assembledA end to end in scallopedfashion and to'provide coupling members adapted to be interposed between the adjacent inwardly converging ends'of barrier elements at the confluence thereof to join said elements together, a further object being to provide coupling members of a construction adapted to anchor the barrier elements to the ground.
A further object is to provide in the barrier bands of a structure of the present character strip sections of sheet metal corrugated transversely thereof for vertical strength and for facility of flexure thereof horizontally.
Another object of the inventionisv to provide simple, durable and inexpensive means serving to truss the arcuated barrier elementsl about the girths thereof, thereby reinforcing their corrugated sections against expansion under outward pressurev from the concave landsides of said elements.

Fig. 6 is aplanfview of the structure shown in Fig. 5. Fig.V 7 is al sectional view taken on the line 7-7 of Fig. 5.' l
The drawing illustrates two of various adaptations of the invention to which it is susceptible. .Fig lshows a terrace barrier or curbing lfollowing the pattern of Va circle, and Fig. 2 shows a different adaptation following a scalloped pattern, which, obviously, may be open more or less at its concave side, or endless as may be desired.
The invention includes a barrier element or band A consisting of a number of sections or strips 10 of sheet metal. These sections; or strips 10 are arranged in endwise succession with overlaps 10a at their adjacent ends lapping one upon the other. `Said sections 10 are uprightly edgewise disposed Yand* a sectional band A formed thereby rests at its lower edge on the ground, the concave side of theband'being the landside thereof. lThese sections or lstrips 10 have corrugations 11 therein extending transversely thereof, the purposeof which is to strengthen the strips'l) laterally in a vertical direction :and to facilitate the .bowing thereof in following the particular arcuate pattern chosen therefor.
The sections orl strips' 10 areunited by fastening together the companion overlaps 16a thereof at each joint between adjacent sections. A preferred fastening for such purposeis a tie clip B of wire. lThis clip B, best shown in Fig. 7, is applied to registering end apertures 12 and to registering intermediate vapertures 13 formed in the bottoms of nesting valleys in the overlaps 10a, said An additional object is to providev fastening ties securk ing together the overlapping ends of sections of barrier bands, which ties have incorporated therein stay members for holding a trussing medium in place about the girth of ra band.
Other objects of the invention reside in the novel combination and arrangement of parts and in the details of construction hereinafter illustrated and/ or described.
In the drawing:
Fig. 1 is a diagrammatical View, in plan, of an embodiment of the invention inform following a circular pattern.
Fig. 2 is also a diagrammatical view, in plan, the same Y illustrating an embodiment of the invention in form according to a scalloped pattern, which may or may not be endless, said embodiment including coupling members between the ends of the arcuated barrier elements.
Fig. 3 is a detail View, in plan, illustrating a fragment of the structure shown diagrammatically in Fig. 2, the same including a coupling member.
Fig. 4 is an elevational View of the structure shown in Fig. 3. Y
Fig. 5 is a fragmentary elevational View, in detail, illustrating the overlapped ends of two of the strip sections which go into the construction of a barrier element or band, said view also showing a tie fastener connecting together the overlapping ends of said sections, the tie yeach other Vwith their extremities spaced apart.
bination coupling and anchoring posts C are provided, one for each confluence of said arcuated barrier bands A.
clip B having incorporated therein an eye 14, which is situated in thevalley fof the outer overlap 10a and which has av portion of its opening substantially ush with adjacent crests of the corrugations 11. Said eyes 14 of the several clips B lie substantially in a common horizontal plane. Joint forming construction, involving said clip B specifically, is the subject matter of a companion application,'the feature of importance here being the incorporation of an eye or equivalent member in the fastener used to tie together the overlaps 10a`of the sections 10 of the barrier bands A. For `the purpose of reinforcing the corrugated section or strips 10 of av band A against expansion under anyv pressure which might be exerted against the band from its inner landside and which mightdistort the band out of the pattern followed in its installation, a trussing medium is disposed across the crests of the corrugations 11 about the convex face of the barrier band A and is held so disposed by the truss-holding members on the fastener ties connecting together .the overlaps 10a of the sections 10. Such truss-holding members are exemplified in the eyes 14 of the clips B by which the trussing medium in the form of a wire 15 is held. In the adaptation of the invention, as shown in Fig. l, the ends of this wire 1S Vare twisted together, as at 16, while in the adaptation shown in Fig. 2, adjacent ends of adjacent truss-wire sections 15a are twisted together, as will soon appear.
In said adaptation of the invention shown 'in Fig. 2, wherein :a scalloped pattern is followed, a number of bowed or arcuated barrier bands A are successively arranged endwise, the adjacent ends of adjacent bands converging one toward the other, but terminating short of Com- Each post C comprises an elongated upright panel 17 of sheet metal having a corrugation 13 along each of its upright edges strengthening the same vertically. Such post C, laterally thereof, spans the space between extremities of its respective ends of its respective barrier bands A and its corrugations 18 nest in the terminal cor- Y rugaticns l1 of said bands. Each of such pairs of nested corrugations 1l, 18 are fastened together with a clip B, the eye 14 of which is in the plane of the eyes 14 of the Aclips B fastening together the overlaps a of the sections or strips 16. The lower end lof each post panel 17 has an extension 17a reaching considerably beneath the lower edges of the bands A upon which `edges said bands rest on the ground. This extension 17d is adapted to be sunk into the soil and, when it is lodged in the ground upon installation of the terrace barrier, the post C serves to anchor its respective barrier bands A to the ground in addition to coupling the same together.
Each post panel 17 has two apertures 19V therein at opposite sides thereof, each` aperture 19 being in line with the opening of the eye 14 of the fastening clip B at its respective side of the post panel 17. In a 'structure ernpioying such post panels 17, each arcuated barrier band A is encompassed by =a section 15a of the truss wire 1S which is made up of such wire sections. Each wire section 15a is strung through the eyes 14 of the clips B which fasten together the ends of the sections or strips lil constituting its respective band Aand each end of such section 15a of the wire 15 is strung through the eye 14 of its respective clip B and also through the corresponding aperture 19 in its respective post C. At the inner side of each post, the two terminal portions of the two truss wire sections 15a, extending through such post C, are twisted together, as at 20, such twists between sections 15a in the wire 15 serving to tighten said wire sections and hold them taut for the eitective trussing of the barrier bands A against expansion under, pressure of the soil curbed thereby.
Changes in the specic form ofthe invention, as herein described, may be made within the lscope of what is `claimed without `departing from the spirit of the invention. Having described the invention, what is claimed as new and desired to be protected by Letters Patent is:
In a terrace barrier, transversely bowed barrier bands of sheet metal transversely corrugated and arranged edgewise upright in endwise succession, in scalloped fashion, the adjacent end portions of adjacent bands converging and terminating short of each other with their ends in relatively spaced relation, 'a coupling post in the form of a panel of sheet metal spanning the spiace between adjacent ends of adjacent barrier bands, the upright edge portion of the post at either side thereof having a vertically eX- tending corrugation therein overlappedby land nesting in the terminal corrugation of its respective barrier band, fastening means securing such bands to the post at the nested overlaps between bands and post, said post having a pair of apertures therein, one at either side of the post adjacent to the corrugation therein, a trussing member of wire for each such band, the same extending yalong the outer convex face of its respective band and having a terminal portion extending through its cor-responding aperture in the post, the ends of said terminal portions of said trussing members having a tensioning` twist therebetween located at the inner side of the post, said tensioning twist uniting the said terminal por-tions of saidV trussing members at said inner side of said post.
