Specification of Letters Patent.

Application filed July 1, 1912.

Patented Feb. 23 1, 15111.

Serial No. 707,128.

T all whom it may concern Be it known that I, THOMAS LIGIITBODY, a citizen of the United States of America. residing at ")l'oungstown. in the county of Mahoning and State of Ohio,have invented certain new and useful Improvements in Concrete-Distribi'lters, of which the following is a specification.

My invention relates to improvements in concrete distributors used for filling molds in the construction of walls or buildings, and for distributing fluid concrete in making street pavements and the like; and the objects of my improvements are, first to pro vide means for pouring concrete, while it is in a fluid state, where it is to be left to harden, without the use of manual transportation, as by whcclbarrows, buckets, hods, etc; second, to atlord facilities for mechanically distributing the concrete at will; and, third, to reduce the cost. 1 attainthese objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the entire machine: Fig. 2, an end elevation; Fig. 3, a plan view.

biimilar characters refer to similar parts throughout the several views.

1 represents a scatt'old, of any convenient shape and material, temporarily erected for the purpose of elevating the mixed concrete to predetermined heights.

2 represents a carrying bed or bucket ordinarily made with a bail bowed over its top and having its bottom ends sleeved on a rod tl'irough the bottom oi the bucket 2, so that when the bucket 2 has been elevated one of its edges, as 3, may trip on a bar 4 and the further elevation of the bail overturns the bucket 2 and empties its contents over its edge 3. The bail and the elevating tackle are not shown as they are no part of this invention and are in common use.

5 is a receiving boX open at its top, 6, and having a, bottom 7 which slopes at a con venient discharging angle to an opening 8. The box 5 is movably attached, as between angle irons, to the scatt'old 1, and may be raised and lowered by tackle 9 to a height required to operate my improvement, while the tripping bar 4 is located on a line with its top.

At a distance from the base of the scafiold 1 convenient for operation in conjunction therewith and for distribution of concrete at the desired places, 1 erect a vertical support which may be a rod or pole but which I prefor to make as a tube. 10, rotating in a foot plate 11 and retained by guys 12, 12. At the top of the tube 10, rotatably sleeved therein and supported by the upper end thereof, 1 place an annular plate 14, to which are attached pulleys 15 and 16.

One end of a trough. .17 is supported below the box 5 and under its opening 8; to its other end a lifting tackle block 13 is attached and a rope passes through it and pulley l6 and leads to the bottom of the tube 10. I thus provide means to raise and lower one end of the trough 17, to hasten or retard the flow of concrete through it. A rope 20 is attached at one end to a tackle block 19 near one end of a trough 21, passes over the pulley 1.5 and extending to near the base of tube 10, enables the operator to raise or lower the end 22 of the trough 21.

represents a receptacle open at its top and having a bottom, 24;. which slopes to one or more openings 0, 0 and has a hole through its middle for the passage of tube 10. The receptacle 23 is held between side bars 25, 25 attached to bottom cross bars 26 and has a bar 27 across its top. The said top and bottom bars 26 and 27 are movably attached to the tube 10 in any way, and, for illustration, 1 have shown opened rings 32, 33 which surround the tube 10 and whose cut ends are bolted to the bars 26 and 27.

31 represents a trough shorter than trough 21 and which may be interchanged with it or be used instead of it when concrete is to be deposited near the base of the tube 10.

28 represents a rope attached to the end 29 of trough 21, passed through pulley 30 and down to the bottom of tube 10.

When it is desired to use tie short-er trough 31 the ropes 30 and 28 are released from the trough '21 and are attached to the respective ends of trough 31. hen trough 21 is in use, trough 31 is left in a horizontal position and the concrete in the receptacle 23 fills it and closes the openings 0 and, conversely, when trough 31 is in use, trough 21 is positioned horizontally and concrete flows only into trough 31.

In practice, mixed concrete is deposited in the bucket 2, which is elevated till its edge, 3, strikes the bar 4:, whereupon its contents are dumped into box 5 and flows out of the opening 8, into the trough 17 and thence through the receptacle 23 into the trough 21, whose end 22 is moved around to where ever the concrete is needed.

The operator, standing near the tube 10, can, by drawing in and releasing the ropes 20 and 28 correspondingly, lengthen or shorten the distance from the end 22 to the tube 10 as well as to raise and lower it.- lVhen the rope 28 is fastened it also serves 'to prevent a backward or upward movement of the trough 21 when its end 22 is raised to flow the concrete into a higher mold of a wall building series.

I find it most convenient to locate the receptacle 23 at a point which is to give it a proper elevation, while the tube 10 is horizontal; clamp the opened rings 32 and 33 about the tube 10, and then elevate it by means of the guys 12.

It will be seen that by my improvements great labor in the matter of transportation and distribution of concrete and the cost and time required for the erection of seatfoldings and platforms for the use of workmen in filling molds in different series and for difi'erent walls of a building are saved.

I claim.

1. In a concrete distributing machine the combination with a hoist and concrete dumping apparatus of a box for receiving said dump, having an inclined bottom and an exit at its base and means for locating said box; a trough supported at one end by said box and adjustably supported at its other end; a receptacle for concrete below said latter end, and susceptible of adjustment and retention on a vertical supporter, said receptacle having an inclined bottom and one or more exits at the base thereof; a plurality of movable troughs fulcrumed under said receptacle and on its base; and means for controlling the'locations of the ends of said troughs.

2. In combination with means for pouring fluid concrete; a receptacle therefor adjustably mounted on a vertical support and havin an inclined bottom and an exit at its base; a trough suspended below said exit;

means for sliding said trough longitudinally and means for rotating its lower end in circles centered on said support.

In testimony whereof I aihx my signature in presence of two witnesses.
