i Application led February 2S, 1921. Serial No. 448,301.

To all lwhom z'z may concern.'

e it known that I, FRANK?. Voor, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use ful Improvements in Hopper and Discharge Chutes, of which the following is a specifi` cation.

My invention relates to conveying devices and comprises a hopper and discharge chute construction for receiving concrete, grain or other fluid or semilluid mass from' a relatively constant supply source and delivering same to varying discharge points.

The main object of my invention is to provide means for distributing material'in various directions at various height-s and at varying distances from the receiving hopper.

In accomplishing this object, T pivot my hopper and chute horizontally on a sole plate which, in turn, is pivoted vertically at a point adjacent the hopper, and a further object of my invention is to 'provide mechanism whereby an operator may easily rotate the sole plate upon its vertical pivot and the hopper and chute upon their horizontal pivot and I also provide mechanism which' enables the operator t0 lengthen or shorten the chute at will. 1

Additional objects of my invention are to provide means for securing the hopper and chute in any desired position and to provide safety devicesto prevent injury to workmen Y likely tovbe caused by too rapid operation of the mechanism. K Y A preferred embodiment of' my invention is-illustrated in the vaccompanying,drawings in which- Figure 1 is a side elevation of the hopper, chute and operating mechanism, mounted upon a suitable base. l

Fig.'2 is a plan of the device. Fig. 3 is a vertical, longitudinal section taken on line 3 3'of Fig. v2. l

Fig. 4 is a vertical transverse section through the chute taken on line 4 4 o Fig. 1. Y

Fig. 5`is a fragmentary top view of a q modified form of chute,-and

Fig. 6 is a transverse section taken on line 6 6 of Fig. 5.

The base 1 of my device is of anyv suitable therethrough construction, rigid enough to support the mechanism and the extended chute when the .the first section 8 of horizontal shaft 13 latter'are filled with material and` may be a substantial foundation, a scaffold, part of A sole plate 2, preferably madev in two porrateatea nee. at', mai.

tions, has vertically spaced bearings4 for a pivoting and holding down bolt 3, is mount-V Y ed upon basel and is free to revolve thereon in a horizontal a brackety 4, having a horizontal bearing 5, in which is journaled a pin 6, carried inv a' plane. Sole plate 2 mountsV frame on the underside lof a hopper 7 and the chute. This otal mounting adapts thehopper and chute tobe rotated in a vertical plane. a f

Chute section 8 maybe of any convenient length, an additional section 9 is preferably mounted on section 8 so as tov slide` longitudinally thereon and one or more additional chute sections, such desired. Each additional section will be slidably mounted upon the preceding secV tion, just as section 9 is'mounted uponsection 8. This mounting is illustrated in Figs. 1 and 4.`

-the material may or to a p oint some distance therefrom. By rotating the hopper and chute upon the horizontal pivot 6, the discharge end of' the as desired. By.

chute israised or lowered revolving the chute, hopper and the'Y `sole plate 2 about the vertical pivot 3, the chute may be located in different radial positionsk about the base.

For revolving sole plate 2 and chute mounted thereon, l provide the sole plate with a circular rack mount aV driving pinion 12 therefor on a which is journaled in a suitable` bracket 14 on base 1 and is provided with an operating crank 15.

For rotating ithe hopper and its chute upon the horizontal pivot 6, I mount an arm and the hopper as 1,0, may be added, if

piv-

It is obvious that by extending or tele-r scoping the chute sections, Y be distributed to a point adjacent the hopperY 11 Y and 16 on sole plate 2l and suspend the chute,

at aVK point substantially spaced from the hopper, by means of a cable 17 over sheave 18 mounted on the outer endiof thearm 16. This cable is carried bysheaves 19 and 20 to a drum 21, the shaft of which is journaled in bearings 22 mounted on the sole plate and provided with a crank 23 by which passes Y means of which the shaft and drum may be rotated to take up cable 1'? and raise the outer end of the chute.

A cable 24e is secured to the outer section of the chute and extends underl the chute to a drum 25, mounted beneath the hopper and rotatable with its shaft by means of a crank 26. lvl/'hen cable 24 is wound up the chute sections are telescopedto the position shown in Fig. l.

When the drums are released, the weight of the chute will unwind cable i7 and when the chute is sharply inclined the outer sections will slide to their extreme positions. lit, because oic hard usage or accumulation of dirt, the chute sections should not slide easily they may be assisted by the workmen.

To hold the hopper and chute in a given radial position, lF provide a latch 27, mounted on base l, adapted to engage the teeth of rack ll. rlhe shafts of drums 21 and 25 are provided withl ratchets 28 and 29 respectively and cooperating pawls 30 and 31. rllhese pawls will bel actuated by gravity or suitable springs to maintaintheir engagements with their individual iatchets and will be provided with handliolds whereby they may be disengaged trom their respective ratchets.

-To prevent a destructive momentum of the descending or extending oliute, l provide individual brakes 32 and 33 for the drum shafts. These are designed to be manually applied by means of their respective handles 34 and 35. I have described all of the above mechanism as adapted for manual operation, but that is optional and it will be understood that suitable power mechanism for operating the sole plate and the winding drums may be utilized it desired. `When my hopper and chute are in use, it will not be necessary to operate the mechanism continuous y, nor, generally, from one extreme to another at one time and itis believed that power means for securing the varying adjustments will seldom be required. Y

Chute section 8 is provided with a. stop 3G adapted to engage a strap 37 secured to the inner end of section 9 and extending across the top of section 8. This stop and strap limitk the outward movement of section 9. Sect-ion 9 is provided with a similar stop 38, and section l0 with a similar strap 39 which operate in the same manner to limit the outward movement of section 10.

Chute sect-ionv 8 is providedwith a U- shaped track 40 yand chute section 9 is provided with a hanger ll slidably mounted in track 40, and sections 9 and l0 are provided with similar track and hanger Ll2 and 43 respectively. In the modified chute shown in Figs. 5 and 6, the upperedge of each chute section is bent inwardly and forms at once a hanger for that chute and a track for incise? the next chute, and these inwardly bent portions are provided with cooperating stop elements la which limit the outward movement oit the chute sections as stops 36 and 38 and straps 37 and 39 limit the movement of their sections.

lf my hopper and chute be used in connection with a concrete mixer, which discharges into hopper 7, they eliminate the long train of workmen with wheel barrows as well as the time consuming and otherwise expensive practice of adding and removing chute sections or platforms which must be built up and mounted on temporary supports. By using my invention, concrete may be applied to places which would otherwise be reached with considerableV dificulty, if at all, such'tor example, as are :frequently encountered in railroad construction work.

Some users having a limited class of work may find my device sufficient for their use with only a single chute section provided and it is to be noted that the horizontal and vertical adjustments et a single section may be obtained the same as similar adjustments of the extensible chute,but the telescoping chute is preferable equipment asV by its use it is unnecessary to move the supply means every time.' the distance from the latter to the distributing point is varied.

l am aware that changes in the torni and construction of parts and details of construction niay be made without departing from the invention or sacriiicing the advantages thereof and l reserve the right to make all suoli changes `and modifications as fairly fall within the scope of theY following claims.
