lily invention relates to a new and useful j improvement in a-floor support for concrete spout, adapted for use in supporting. a'con 1 crete spout which is used for distributing concrete In constructing buildings formed permit the plastic material to flow, downwardly by gravity. through troughsfto be f commonly used.

fromconcrete. I q i In constructing buildings of concrete, it is-cust-omaryto erect/an elevating-tower of suflicientheight to permit the elevating of the plastic material to aheight which will distributed to the various portions of the buildingwto which the concrete is desired.

,These troughs are "generally constructed in sections, the upper end of each adjacent sec tion being positioned directly beneath the lowersend of the'uppen preceding section. so

that the concrete or plastic material flowmg from one section'is deposited mtothe' upper [end of the next lower :section. Owing' to the great weight of 'theflplastic material which" is poured down these ably supported, either by'npright supporting standards, or by overhead cables,the overhead cable system being the one most The. sections "of the troughs which are approaching the'position at which the concrete is deposited in. the

' forms arranged for it,"do not permit ofthe I, is principally due to the fact that'it is, nec l essary to have vthe lower section pivoted,'-'so that it maybe turned in various directions A "volving' considerable" expense I owing to the overhead attachmentfto any greatextent at theirxlower end, with the result that counterbalancing trusses are generally attached to the upper end of the trough and weighted at one end, the opposite end being heldiin engagement with r the trough "adjacent its lower end, soasto relieve the lower end' of 1 a portion of the downward pressure result ing from the weight, This is particularly true of the last section of tlie -fl-c hute, -or trough, down which the concrete runs and to distribute the concrete-foyer. a large area. Thecons'truction of the; counterbalancing truss is an expensive, arrangement andv the assembly of it is difiicultand involves much labor. "The weighting of the counterbalancing truss is also aditficult operationjinlabor used. I

In the present invention,"I have,tdesignedi. a'support for the lower 'section 'of the concrete chute 0r spout inw'hich 'thecon'crete,

itself,; it made, to counterbalance the chute,

.so that the""-lower-end'of the trough,; or chute, is relieved largely ofthe downward pressure;

It is anz'objectjof the, present inye-ntion to provide such. ase'ction offa trough in which-the use of a counter-balancing truss,

or other assembly of weight, may be eliminated. I V V Another object ofthe invention is the provision of means for mounting the lower section" of thetrough, which will be simple in structure, and easy of operation and assembly.

I p '70 Another object "of the invention is the provision". in connection with the lower trough, such an arrangement of means for carrying the lower trough; which may be moved bodily "and. which'f-will permit a rotation of the trough freely about its updistributin Other objects will appear hereinafter The nvention consists in the combinaperend'ras a pivot, "to a fford a means of thef1 3lasticgmaterial ver" a "large area.

comprises alplatformyor base,'12, which is i formed preferably square and which is: pro

ing a pocket 18 formed-thereiny'the upper end thereof beingpreferably semi-spherical.

The upper end of the post 'isas' shown in i the block 17 on the post 1-1.

the upper surface of the trough are anguso as to relieve the trough 16 of aportion v of its downward thrust, the structure being Fig. 3 formed arcuate and the-pocket 18 is of suificient 'sizeto permit a ITIOVGHIGDi'. o'l? larly turned bars 19, which hare" their ends 20 angularly turned and secured to the block 17 by any suitable fastening means.

These members 20 project downwardly and i are angularly turned at their ends and se- .,cured to angle irons 2-1 and 22 which "are formed bow-shaped and pass at opposite sides oflthe'postl, as is clearly seen in Fig; 4. The ends of these members 22 and 21 are attached to the trough by rivets,

bolts or other suitable securing means. Crossbars 23 and 24 are secured to the angle irons 21 and 22 by suitable bolts 'saidangle irons 21 and Y22 being provided with. a plu- .rality of openings, as shown in Fig. 4, for

the projection of these securing bolts therethrough, so that/the position of the bars 24 and 23 may be varied on the angle irons 21 and 22. It will be noted that the block 17 is. mounted upon the trough 16 at'approxivmately twice as great a distance from the lower end ,of the trough as from the upper .end, two-thirds of the. trough projecting downwardly from the block 17 and onethird of the trough projecting upwardly.

be rocked upon the postli, the clearance of thepocket 18 in the block 17 permitting this rocking movement. The cross bars 23 and 24 are arranged to limit the rocking movement, the ad ustment of these bars 23 and 24: on the angle irons21, and .22 determining the incline of the trough 16 relatively tothe post 14. Thermembers 19, being extended over the 'otherside of the trough, will serve to prevent the trough being bowed upwardly at the point of sup- The section of trough 16 which is above the upper end of the trough 16 and in communicationtherewith being also filled with concrete,jor plastic material, is exerting a certaindownwar'd force. As the concrete in the. portion of the trough 16 extending be- ;low the pointof connectionwith the post 14 exerts a downward pressure through the angle irons21 and 22, this downward thrust is delivered to the upper end of the trough,

such'- that the downward thrust of the trough '16 below the. point of connection with the, 130st, iscounterbalanced by the ldownward nthriust of. the portion of the trough 16 which is above the" pointof con- En'ibracing.

The structure is such thatthe trough may nection with the post 14. In thisway the concrete itself is used to counterbalance and the. presence of heavy counterbalancing weights is dispensed with, thus adding to the efficiency ofthc operation and reducing the cost of installing a concrete distributor of this class. It is apparent that the support is one which is positive and the struc ture such as may be made durable.

While I'have illustrated and described the preferred form of structure, I do not wish to limit myself to the precise form of stru'cturcshow'n, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having thusdescribed my invention, what I claim as new and desire to secure by Let ters Patent is: i
