Definitions

  • TOPPLE TOWER SUMMARY OF THE INVENTION I shall call my invention the Topple Tower since this describes the form of the structure and the falling action by which it is put into effect or executed.
  • FIG. 1 shows the tower in the upright position. This is the position in which it is constructed, and in which it remains unless or until felled into a horizontal position as an obstacle.
  • it is fabricated of steel reinforced concrete on a reinforced concrete or masonry foundation. It consists of an elongated trunk-like structure with a plurality of projecting limbs as shown in the drawing.
  • the tower's height may be expected to be some 70 to 100 feet, but may be larger or smaller. Other proportions are about as shown on the drawings, in which the tower itself is about 6 feet in thickness, tapering to about 4 feet at the top.
  • the projecting limbs are shown about 8 feet long, about 4 feet thick where they join the central structure, and taper to about 2 feet thickness at their extremeties.
  • the tower remains in the upright position until the obstacle is needed. Should an enemy attack be launched or known to be imminent, and upon the decision of the commander of friendly forces; the obstacle is quickly executed by detonating an explosive charge in a chamber or chambers which are built into the base of the tower.
  • the base of the tower is constructed in two or more separate parts. See FIG. 2 and 3 which depict a preferred form of the tower base showing the chambers for explosive. Chambers are indicated by the letter A.”
  • part of the tower base is destroyed causing the tower to topple or fall in the direction of the portion of the base destroyed by the explosive charge. This permits the structure to block the area or passage desired.
  • a series of towers will be constructed so that when felled they will either join or overlap to form a continuous barrier across a threatened area or avenue of approach.
  • the trunk of the tower tapers from base to top.
  • the trunk of the tower tapers from base to top.
  • at intervals are groups of projecting limbs 1 1 set at approximately right angles to each other and to the trunk of the tower.
  • These limbs are of the same material as the tower and are employed for two reasons: firstly, the limbs projecting from the tower on the sides toward which it falls are designed to be driven into the earth by the weight of the tower structure and the force of its fall, thus anchoring the obstacle in place and rendering its removal more difficult. Secondly, those limbs on the opposite sides will be projecting upward and outward extending the height and breadth of the obstacle, rendering it more difficult to surmountby any vehicle or mechanical device.
  • attachments are to be built into the structure, in the form of metal studs, rings or clamps, to which coils of barbed wire are attached.
  • the reinforced concrete limbs serve to support and stabilize the aforementioned barbed wire entanglements which add to the antipersonnel value of the obstacle and inhibit enemy breaching operations.
  • FIG. 4 shows the tower in vertical cross section and a typical location for the attachments for barbed wire coils. Attachments are indicated by the letter B.
  • FIG. 5 shows an end-on cross sectional view of the tower after it is felled into its position as an obstacle.
  • the lower projecting limbs are shown imbedded in the earth and indicated by the letter C.”
  • the limbs from the other side of the structure are shown projecting upward and outward and are indicated by the letter D.”
  • Coils of barbed wire are shown in the preferred position at the junction of the limbs along the trunk of the tower and indicated by the letter E.
  • the height of the obstacle as shown is about 15 feet, but nothing used in this description is intended to limit the total size or proportions used in this type obstacle.
  • Antitank ditch this obstacle is an obstruction to peacetime movement if constructed before hostilities. It interferes with land usage and moreover is relatively ineffective as a military obstacle since it is easily overcome by use ofportable bridging.
  • the intended mode of employment of my invention consists of the construction of a series of towers designed as l have described during peacetime. These would be located so that when felled they would block roads at defiles.
  • a complete barrier system would employ a series of towers located so that when felled they would form a series of continuous obstacles, blocking all tank passable terrain.
  • a barrier system would be emplaced in the vicinity of and along a threatened frontier such as that between East and West Germany, between North and South Korea, along the borders of Israel, Northern Greece, Eastern Turkey or any similar boundary between potentially hostile states and nations having mutual defense treaties with the United States.
  • a state of high readiness can be attained by pre-placing the explosive charges, locking or sealing them in the chambers described.
  • the charges can be tired electrically from a remote location if desired.
  • the construction of the towers involves commonly employed engineering techniques.
  • a sturdy foundation is constructed, the reinforcing steel is installed and 4 forms for the concrete are erected on the usual way.
  • a dense concrete is poured into the forms, probably employing a bucket crane as in the construction of concrete dams or bridge piers. The concrete is allowed to cure and the forms are removed.
  • An upright tower adapted to be felled to provide a barrier to impede the movement of armored vehicles comprising an elongated trunk-like structure made of steel-reinforcedconcrete supported on a tower base, said elongated trunk being formed to include, at intervals along its length, groups of projecting limbs set at approximately a right angle to the axis of the trunk, said tower base including chamber means adapted to receive explosives for destroying a portion of the tower base to thereby fell the tower when the explosives are detonated.
  • a tower as recited in claim 1 in which said projecting limbs are positioned at approximately right angles to one another.
  • a tower as recited in claim 2 in which said base is constructed in two or more separate parts with at least one of said parts being formed with said chamber means for the reception of said explosives.
  • This invention relates to automatic gate installations such as are used to control the flow of water in canals.
  • installations of the indicated type are usually constructed of narrowed passages so that gates of reduced dimension may be used for reasons of economy of construction even though head losses may be substantial.
  • This type of construction however, has a distinct disadvantage when used with gates designed to automatically maintain a constant water level upstream therefrom and having for this purpose control floats lo cated on the upstream faces of the aprons thereof. This is due to the fact that in the elongated funnel-shaped type of entry heretofore used, the localized increase in speed of the flow resulting therefrom causes a lowering in level of the water discharging through the opening passage.
  • the automatic gate does not control the level in the canal, as desired, but rather the level in the narrowed passage. It has been found that because of this condition, the level in the upstream reach of the canal will be higher than in the narrowed passage to an amount dependent upon the flow rate.
  • the primary purpose of the present invention is to provide a narrowed passage for automatic gates of the indicated type which is so constructed that the creation of a localized excessive speed of flow therethrough will.
  • FIG.' 2 is a view similar to FIG. ll showing an auto-- matic gate fitted in a canal in accordance with the invention
  • FIG. 3 is a perspective sectional view showing in enlargcd detail the structure of MG. 2;
  • FIG. 4 is a diagrammatic, vertical sectional view of the entry portion of a narrowed passageway of dil ferent construction in accordance with the invention:
  • the reference G indicates generally an automatic gate mounted in a reduced section or passageway 3 of a canal C in which the water flows in the direction of the arrow F.
  • the gate 6 is constructed to maintain automatically a constant water level upstream from the sector-shaped apron 1 thereof and for this purpose is provided with a control float on the upstream face of its apron ll.
  • the reduced section 3 is connected to the upstream reach 6 of the canal C by along funnel 5 whose crosssectional area is progressively reduced from that of the canal to that of the reduced section.
  • funnel 5 whose crosssectional area is progressively reduced from that of the canal to that of the reduced section.
  • the present invention contemplates foreshortening the entry or up-' stream end of the narrow passageway 3 to provide a short connection generally designated 1 which does not modify the level of the canal flow by a localized speed increase, as in the case of the long funnel 5.
  • a short connection generally designated 1 which does not modify the level of the canal flow by a localized speed increase, as in the case of the long funnel 5.
  • the gate will correctly control the level of the upstream reach dot the canal.
  • Fifi. 3 ofthe drawings there is shown in detail a structural embodiment of the short connection 7 depicted generally in H6. 2. in H6. 3, as in FIGS.
  • the canal is generally designated C
  • the narrowed canal section is generally designated 33.
  • the gate is generally desipiated G
  • the flow of water in the canal is indicated by the arrow F
  • the portion 4 of the canal adjacent to the upstrearnend of the narrowed canal section 3 is separated from the latter by a vertical wall disposed at right angles to the longitudinal axis'of-the canal and constituted of two vertical side sections 8,8.
  • the short connection generally designated 7 is constituted of inclined or truncated surfaces g of generally triangular shape located between and cut out'of what would be the junctures of the inner edges of the vertical wall sections 3 and the side walls id of the marrowed section 3, and disposed at obtuse angles to such wall sections it and side walls lid.
  • the apexes of the surfaces are adjacent to and short of the tops of the wall sections 8 and their bases adjoin the ends of an inclined from the raised bottom edge of the entry opening in the rowed section 3 (note lFlG. il.
  • each cut face Q with the associated side wall lid of the narrowed-sec tion .53 is a straight line l5 which may be readily constructed in the surfacing concrete.
  • line llS' is at a minimal distance from the line of contact which the adjacent edge of the sectorshaped apron ll of the gate makes with such associated side wall id.
  • the gate (3 is constructed as an automatic. I
  • each side of such connection is formed of two cut faces 12 and 13'.
  • the cut face 13 is generally triangular in the manner of cut face 9, but it is not as high as'the latter so that the apex of the cut face 13 is located a substantial distance below the top of the narrowed section 3.
  • the cut face 12 widens the entry opening in the transverse wall so that the areas of the .vertical sections 8 thereof are considerably reduced.
  • the angle or connection 7 between the transverse or vertical wall and the narrowed section 3 is formed by providing on each side thereof at the entry end of section 3 a first cut face 12 whose intersection with the associated side wall 18 of the narrowed section 3 is cut in its lower area by a second cut face l3.
  • the line of intersection of the faces 12 and 13 with an inner wall 18 of the narrowed section 3 will be composed of an angular or polygonal line 16,17.
  • the angular line 16,17 is located at a minimal distance from the line of contact 14 of the gate apron 1 (note FIG. 4).
  • the upstream end of said entry connection being p composed of vertical partition walls on each side of the canal and disposed perpendicularly to the axis of the canal, the angle formed between each of said partition walls and an associated side wall of said narrowed section, and constituting one side of said foreshortened I g I tion for installation of a water gate, the side walls of fi fla on.
