WILmAM r. KAssEBAUM,

a Application'filed June 21,

T0 all whom it may concern: v 1.

. Be it known-that I, WILLIAM F. KAssE BAUM, acitizen of the United States, residing at Hebron, in the county of Thayer and State of Nebraska, have invented a new and Improved Foldable Wicket ,for Dams, of which the following is a specification.

- This invention relates generally to improvements in wicket dam structures and more specifically has referenceto an improved fold'able bracket or wicket, and primarily my invention has forits purpose to provide an improved dam structure ofthe general character stated of a relatively in-, expensive nature and which is especially designedfor being used on the top of cement or other forms of water dams so as to provide for adjusting the dam of vwater, and for collapsing all of the brackets that constitute a part of a dam section. or gate to drop onto, the dam top to allow the free escape'of surplus water:

Another object of 'nvention is to provide a simple and easily actuated means for releasing all of the wicket or bracket members connected with a gate or damsection, in unisom and ,for 'dropping flatwise along.v the top and inneredge of the dam wall, out of the way along such wall top, and in which the bracket members areso formed that when the dam or gate section is swung up the brackets automatically open out and lock themselves to their extended position so as to hold thenbracket or gate at the proper place; f i 1 With other minor .objectsfin view, that will' hereinafter be apparent, my invention comprises a fol'dable bracket orwicket for damsections that embodies the peculiar) features of construction and arrangement of parts, fully set out in the following detailed description, specifically mentioned in the appended claims and illustrated in the accompanyingdrawings in which: I

subistantially on the line 3- 3. "O Figure 1, an a Figure/t is a perspectiveview ofone of my improved brackets detached from the gate or wicket wall.

In the practical development ,ofmy invention, my improved bracket isvmade out of strips of strap metal, preferably-steel, I about two inches wide and about one-half z inch'thick, and: in practice, four or five of attached to each wicket or gatese'ctiom-the several brackets for eachgate'se'ction being-- adapted for collapsing orffolding down at Each bracketincludeawhat is hereinafter termed a base member l, and an upright member 2 whose lower-end is connected-to the outerend of the base member 1, by-a hinge 3 that is designed to permit the upmember 1 when the gate lisj lowered, as is to I ,v v c v.35 ofthe base in'ember 10f the brackets, with their attached gate secs tion from pulling over toward the stream,

such movement of thebr'a'ckets and the'gate being further resisted by the anchormg .bolts l4 that, pass throughthe basemembers '1. and are embedded in lthe concrete dam wall asis clearly shown in Figure ,2.

wicket section 51 are fixedly attached to the back of the said wicket'or gatesection'by bolts 6 I 6 that pass through; the uprights'2 of the bracket and the gate section 5 that s y r member 7 has an inwardly and downwardly inclinedfiat extension 770, such extension constituting the upper connection for a col,- lapsible brace 8, the construction of the brace 8 being best shown in Figures 1 and 2 of the drawings, by reference to which it will be seen, the said brace 8 comprises an upper section 80 and a lower section 81, the

upper section being composed of two strips,

fiatwise arranged and connected by a stud.

pivot 9 to the extension 70 oi the hinge member 7.

The lower section 81 is a single flat strip whose lower end rests fiatwise upon the angled portion 10 of the base member 1 and it is swivelly connected thereto, (to swing laterally with respect to said members 1 and 2) by a staple 91 that projects from the portion and through an aperture 81, in the lower end of 'thesection 81 as shown.

I he uooer or free end of the brace section I 81 exen'ds between two fiat strips that constitute the upper brace sect1on-80 and about midway the length of the brace 8 the lower section 81 islpivotally oined to the upper section strips'j'by a stud nut 12 and at its extreme upper end the brace member 81 has an outwardly pro ected flange 82 that constrtutes" a stop for limiting the lateral swing or" the brace members 80 and 81, when. the

gate seetion, with the uprights 2 of the bracket are swung up to the vertical POS'lition; "The two brace sections 80 and 81,

when the gate section is dropped in the manner presently explained, collapse by bending laterally with respect to members 1 and 2 as indicated by the arrow a on Figure 2 and when the is'lifted to its upright position the said brace sections 80 and 81 move laterally in the opposite direction, see arrow Z), until they reach their fully extended alignment, to which adjustment they are limited by the stop flange 82. The two sections 80 and 81, as they reach their extended position become automatically locked and are held from being collapsed until a force is applied, suflicient to pull the brace members laterally in their flatwise condition.

y To provide for conveniently collapsing the bracemembers .8 of all of the brackets on a gatcseetion to be lowered, each flange portion 82 of the lower-brace sections 81 is pro- 8 vidcd with an eye 83, and to the said eyes o 5 tllOjlGllGS o1 brackets a. rod or cable .13 is swivelly at arched, the connection being such that a pull on the rod or cal'ilc 13 in the direct on oi the arrow 0 swings'all oi the brace sections to a collapsing position and in so doing the uprights 2 of the brackets, with thenattached gate sections, are caused-to swing backwardly to close down over the required to stamp or shape up the'bracket sections as they-may be easily shaped up by any skilled blacksmith. The cost of making the brackets and their upkeep, when operatively assembled, is sosma'll that, their use is especially desirable 'at places where gates or wickets are urgently needed to hold back the water when rapidly rising during floods and the like. I

What I claim is: r

1; A'wicket for dams comprising a base member adapted for being fixedly attached crosswise of the dam wall top, a gate hingedly connected to the'base member to drop back onto suchmember and a prop connectedto the gate and the base member, the said prop consisting of an upper section joined to the upper edge of the gate for Vertical and lateral movement with respect to the gate, and a lower section, the said lower section being swivelly connected to the base member for vertical and lateral movement with respect to the said base mem-- her, operative connections pivotallyjoining the said prop sections to one another to swing, laterally, the connections for the prop sections being such whereby to cause them to fold flatwise onto the dam .wall top as the prop is collapsed when the gate drops,- and extend the prop sections as the gate is lifted. p

2. A wicket for dams comprising a base member adapted for being fixedly attached crosswise ofthe dam wall top, agate hinged to the base member to. drop back onto such member and a prop connectedto the gate and the base member, the saidprop consisting of an upper section oined'to the upper edge of the gate for vertical. and lateral movement with respect to the gate, and a lower section, the said lower-section being swivelly connected to the base member for v vertical and lateral movement with respect I to the said base member, the said two prop sections being pivotally connected to one another to swing laterally, the connection of the prop sectionsbeing 'such whereby the 12 prop will fold fiatwise onto the dam wall top when it collapses when the gate drops, and to assumeits extended or prop adjustment as the gate is lifted, one of the prop sections having a laterally projected flange 1 2 that constitutes a stop to limitthe extended adjustment ofthe two prop sections.

3. A wicket for dams comprising a base member adapted for being fixedly attached crosswise of the darn Wall top, a gate hingedly connected to the base member to drop back onto such member and a prop con.- nected to the gate and the base member,

the said prop consisting of an upper sectionconnected to one another to swing laterally,

the connections for the prop being such whereby the prop sections will fold fiatwise onto the dam wall top as the gate drops, and to assume the extended or prop adjustment as the gate is lifted, one of the prop sections having'a laterally projected flange that. constitutes a stop to limit the extended adjustment of the two prop sections, and means connected to the'said flange portion for pulling the two sections to collapse them, to thereby permit the gate to drop with the collapsed prop sections onto the dam wall top.

4:. In a dam wicket of the character de scribed, the combination with the wicket or gate section and the dam wall; of a plurality prop consisting of: a base or sill member of spaced props for the gate or wicket, each 7 adaptedfor'being rigidly. mounted cross-'- wise of the damwalltop and upright means I for securing the upright to the'back of the wicket or gate, a hinge joint thatconnects V i i the lower end of the" upright to the outer 'end of the base member to thereby provide for dropping the gate member back onto the baseor sill, a brace portion comprising an upper and lower section, the two sections being pivotally joined for swinging laterally in the same directions with respect to the gate and the base member, the lower section being swivelly connected to the inner end of the base'member, theupper section being. likewise connected to the upper end of the gate and a flexible pull connection that oins with one section of all ofthe props whereby' to collapseall of the said props atthe same time to permit the gate to drop back and cause the prop sections; to

fall fiatwiseon the wall top, the saidprop V sections, automatically resuming their extended or prop adjustments as the gate is lifted in the usual way.
