may concern:

Be it known that I, FRANK R. MCCUNE, a citizen of the United States, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in Hoppers, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings,

forming a part hereof. My invention relates to improvements in hoppers, especially designed cured to the upper margins of the hopper 5. Secured to the end walls of the hopper 5 are the angle plates 7 which embrace 1e track rails 3 to guide and direct the hop er in its movements relative to the tower. Secured to the hopper 5, adjacent its lower margins, are the angle plates 8.

9 designates the bottom of the hopper having converging walls the upper margins of. which are reinforced by the angle plates. 10, which angle plates are detachably secured to the angle plates 8, by means of bolts 8.

11 designates a cylindrical extension of the bottom 9 which is secured to and carried by Secured to the lower extremity of the neck 11 is an annular collar flange 13 and suspended from 13 is a collar 14 having an outturned ange 15. Arranged to engage with the flange 13 of'the collar 12 and secured in any suitable manner to the collar 14 is the distributing spout 16.

for use in towers and employed in receiving and distributing concrete for building purposes, the object of my invention being to construct a hopper of simple and durable construction which may be readily moved vertically in the tower and securedin various positions therein. i

A further object of my invention is to construct an improved gate valve to .be em-v ployed in the hopper and to provide means or readily operating the valve from the top For the above purposes my invention con By the arrangement of the collars 12 and sists in certain features of construction an 14 it is obvious that the spout ma be turne parts aswill be hereinafter pointed out in the by the accompanying relative to the hopper as required to position the discharging end of the spout at different points throughout a building in course 0 erection.

Embracing the neck 11 are the angle plates 17 the body portions of which are space a slight distance apart, and arranged to slide between the plates 17 is the gate valve 18 the neck portion 11 being at 19 to ermit movements 0 valve 18. The valve 18 is provi arrangement of more fully set forth, claims and illustrated drawing, in which:

Figure 1 is a side elevation of the complete hopper showin a portion of the tower, a portion of one o the supporting beams being broken away; Fig. 2 1s a planof the complete hopper illustrating a portion of the tower; Fig. 3 is an enlarged, detail, vertical, sectional elevation illustrating my improved valve and a portion of the valve operating-means; Fig. 4 is a sectional plan taken on the line 4-4 of Fig. 1; and, Fig. 5 is a vertical, sectional elevation of the upper portion of the hopper illustrating the beams .for supporting the hopper, taken on the-line 5-5 of Fig. 2. Referring by numerals. to the accompanying drawing: 1 designates the uprights and 2 the ledgers of a metallic tower.

3 designates track rails extended vertically of the tower and secured to the ledgers.

4 designates I-beams supported upon the ledgers 2.

5 designates the body portion of my improved hopper which is suspended from the ded with a reduced portion 20 bifurcated at its free end, and spanning said bifurcated end is a strap 21. Secure to the neck 11 in a plane above the valve 18 is a collar '22 having an inte ral' arm 23 and pivoted to the arm 23 is a be crank lever 24, the long arm of which is bifurcated and embraces the strap 21. Secured to the body portion 5, adjacent its top and on one of its end walls, is a bracket 25 and pivotally mounted in the bracket 25 is lever 26, and suspended from the short arm of the lever 26 1s a rod 27. Pivotally secured to the bottom 9 of the hopper is a lever 28 which is connected with the rod 27, and connecting the rod 27 and lever'28 with the short arm of the bell crank lever 24 IS a I-beams 4 by means of the angle irons 6 sea bell crank
