Be it known that I, ARTHUR L. SMITH, a citizen'ofthe United States and, resident of St. Louis, Missouri, have invented certain tive view of new and-useful Improvements in Devices for Distributing Concrete, of'which the follow- My invention relates to an improved device for distributingconcrete, and has for its object to rovide means wherebyconcrete, during t e process of concrete build-.

'-ing construction, is distributed from a single source tomany difi'erent points of deposit.

In the drawings-Figure 1 is a perspeca device embodying my invention. Fig. 2 is an enlarged side plan view of the distributing hopper employed in my invention and its connections. Fig. 3 is a side plan view of the lower end of the first distrlbuting pipe em loyed in my invention,

showing its mode 0 adjustment to the sed- 0nd distributing pipe. Fig. 4 is an enlarged plan view of the pin employed as a fastener 1n. suspending the upper end of the first distributing pipe; showing the upper and lower ends of said pin insection. Fig. 5 is a top plan view of the turntablevand track, emp oyed in my invention. Fig. 6 is a transverse vertical view in section of the same taken along the line 66 of Fi 5.

As illustrated in the'drawmgs, the device of my invention employs a platform 7 rotatably mounted upon the track 8 and inner concentric track v9 by means of the wheels 10 and 11. Upon the platform 7 the concrete mixer 12 and the motor 13 are mounted; the platform 7 carrying the derrick 14. The derrick 14 is provlded with the boom 15 at its top, said derrick and boom-serving to suspend the first distributing pipe 16 by means of suitable block-andtackle connections indicated in the drawings by the numeral 17; the position of the boom 15 'being'controlled by the block 18 and itsconnections.

The concrete mixed in the mixer 12 is conveyed in a bucket 19 elevated by means of the rope 45 to the point where the hopper 20 is mounted upon the derrick 14. The bottom of the hopper is provided with. the closure 21 operated by the lever. 22 through the connecting members 23 and 24; the lever 22 being pivotally mounted on the beam 25. From the beam 25 the suspending members 2626 extend to a point beneath the mouth Specification of Letters Patent. 7 Application filed February 23, 1909. Serial No. 479,479.

vkey 30; the object of this construction. being to avoid the use ofa bolt and nut, the action of the concrete in time rendering it impossible to remove the nut from the bolt. The

lower end of-the pin 28 is provided with a 'slot 31 to receive the key 32 by means of which the yoke 33 is retained in position. The chal serves to hold the pin 35 which passes thr ugh the lower. wall of the distributing pipe16 and is secured. in place by means of the key 37 passing through the pipe 16 is proupp'erend, and at its lower end is provided with the arm 39 supporting a chain 40, by which the pin 41 is supported, the pin 41 passing through the bottom of the second distributing pipe 42 and being pipe 42 is-provided atits upper-end with the hopper 44. It will thus be seen that the lower distributing pipe 42 is so suspended with reference to the mouth of the upper distributing pipe 16 that it can be revolved throughout a radius of 360; while the upper distributing pipe 16 may be similarly revolved'with reference to the bottom of the In the use of my invention, the tracks 8 and 9am laid as nearly as practicable at the center of the building to be erected. The

concrete is then mixed, elevated and dis tributed through the pipes 16 andZEto the various forms or molds to-be filled; the hopper 20 being carried by the derrick 14 at a point above the plane of the highest point -to which concrete is to be distributed. The

rate of flow of the concrete from the hopper 20 to the point of distribution is governed by the consistency of the concrete and the angles at which the pipes 16 and 42 are respectively mounted.

en desired, a third or anydesired num ber of additional distribution pipes may be added, the first of the pipes'so added being ,suspendedfrom the mouth of the pipe 42 and the others added to connect therewith in their order. But I have found in practice secured in place by a key 43. The

that {the structure shown with but two dis- I tributinig pipes is operative on a scale suffi. ciently arge for the construction or buildings. of any usual size.

' Havin fully described my invention, what I claim as new and desire tohave secured to me by the grant of Letters Patent, is: 1. In a device for distributing concrete, -means for elevating the concrete to a point above the lane of the Work to be performed; a iopper adapted to receive the concrete so elevated; a primary distributing pipe revolubly mounted beneath the v hopper; and a secondary distributing pipe revolubly mounted beneath the mouth of the first-named distributing pipe, substantially as described.

2. In a device for distributing concrete; means for elevating the concrete to a. point above the plane of the Work to be per- 1ed; a hopper adapted to receive the ted." a prin'lary distributtinted neath the nbu pipe revolubly moi e th o the first-named I controlling the flow or: concrete from. the hopper to the fiI'St'lli zed distributing pipe substantially as described.

the angle at which said distributing pipes are mounted, substantially as described.

4. A plant for concreteconstruction'comprising an elevator provided With means for receivingand raising concrete, a' chute adapted to receive the concrete raised by the elevator and to deliver the same by gravit a said chute being inclined and being movab e horizontally to shift the point of delivery of the colpcrete, the lower end of said chute being provided With a horizontally rotatable delivery pipe.
