Patented Feb. 39, 1931 Are HENRY G. ONSTAID, OF MINNEAPOLIS, MINNESOTA, ASSIG-NOR TO EEG-LES CONSTRUC- TION COMPANY LIMITED, OF MINNEAPOLIS, MINNESOTA LOADING-SPOUT DEVICE Application filed March 23, 1929. Serial No. 349,356.

My invention relates to leading spo vices, and while intended more par for use as a dock SpOllt for loudiz or other material into boats from buildings or bins located on docks, it will be understood that it is susceptible of use for loading grain or other material into other cont ers such as freight cars. An object of the is to provide a devi v of this 0 which both the incli otion and the the spout may be varied as desired 0 effect the loading operation to the best advantage.

Another object is to provide power operated means whereby the inclination of the spout may be readily yariz-zl and to provide indepci'idently controllable power operated means whereby the length of the spout may be read ily varied. Another object is to so construct both of the power-operated mechanisms that the spout will retain the position into which it is adjusted both in regard to inclination and length until one or both of the mechanisms are again operated for changing the set ing of the spout.

The full objects and advantages of my invention will. appear in connection with the detailed description thereof, and the novel features of my inven ive idea will be particularly pointed out in the claims.

In the accompanying drawings which illustrate a practi il embodiment of my inveiv tion, Fig.1 is a. sectional clc ational View showing the delivery end of the spout positioned zibove a boat. Fig. 2 an enlarged iew in horizontal section on the line 2 2 of Fig. 1. Fig. 3 is View in vertical section on the line 33 of Fig. 2. Fir l is an elevational VlGW shown from the line ll oi 2. Fig. 5 is a further enlarged View in section on the line 55 of Fig. 2.

In the exemplilication of my invention shown in the drawings, the numeral 10 designates a wall of a building located on a neck 12 to which boat l lis tied up. A delivery pipe 16 leads through the wall 1 0 and is secured to the upper section 18 of a downwardly extending gooseneclr having a lower section 20 swivcled to the upper section. An upper boom member 22 and a lower boom member 24 are secured together at their inner ends in tion 20, the lower end cl this section being a curved so to fit into the member for different inclinations ot the latter. A. second spout member 38 is telcscoped on the spout member 3st so as to be capable of sliding movement up and down thereon. A cable 40 secured at one end to the upper end of the spout member 38 and secured at its other end to the lower end oi": this spout member passes over a pulley 42 carried by the lower end or" the boom 24. The cable 40 serves to maintain the spout member 38 at the desired inclination as it is slid up and down to change the length of the spout. Secured to the upper end of the spout member 38, tnere is a cable which passes over a pulley l6 secured to the building. By pulling on the cable l the spout member 38 will be slid upwardly on the spout member 34: and when the cable 'I-l is released, the spout member 38 will shde downwardly by gravity. In this manner, the length of the spout i'uay be varied as l'ouud desirable. Secured to the outer end or? (lit boom 22, there is a cable 46 which passes over a pulley 48 secured to the building. By pulling on the cable 46, the booms 22- and 2d will be raised and when the cable i6 is released the booms will lower by gravity. The spout members 34 and 38 will be conjointly swung up and down with the boom members. The lower portion of one of the cables as for instance the cable 46 winds on a drum 50 while the lower portion of the other cable as for instance the cable 4 lwinds on e. drum 52, these two drums being mounted in brackets 54 secured to the building. The two drums are operated in the same manner and hence a detailed description in regard to one of them may be considered as also applying to the other. lVorm gearing 56 is interposed between the shaft of the drum 50 and a shaft lib cured to the respective ends ot a sleeve e8 which feathered on a shatt '70 a. iown in Fig. 5. The shaft is mounted 1 bearings '(Qhnd H as shown in 2 and 4t. Secured to the outer end of the 21 aft 70, there is a wheel 76 which is driven by a belt or ch i drive 78 trained around a wheel carre" by the shaft of a motor 82 as shown in 2. By referring to Fig. at, it will be understood that the lower drum 52 is adapted to be driven in a sin'iilar manner through a bevel gear 62 engageable by bevel gears 6% and 66 secured to a sleeve 68 feathered on a. shaft 70 which driven from the shaft 70 by a. sprocket chain 83. The sleeve 68 is engaged by the inner end of a shifter bar S-l while the sleeve 68 is engaged by the inner end of a shifter bar 86. The outer end ot the bar 8 is pivoted to a crank arm 88 secured to a sleeve 90 rotatably mounted on a rotatable rod 92. A handle 9-l secured to the sleeve 90 serves to rotate it and thereby br 1g one or the other of the gears and (56 1.1..) engag mcnt with the gea 62 according to the direction in which the handle 9&- is mo ed. The outer end of the bar 86 is pivoted to a crank arm 96 secured to the rotatable rod 92.

handle 98 secured to the rod 92 serves to ro- (ate it and thereby bring one or the other of the gears G l and 66 into engagement with the gear 62 accordii a" to the direction in which the handle 98 i... moved. By referring to Figs. 2 and 3, it will be seen that the rotatable rod 92 is mounted in a bearing 100 inside the building and in a bracket bearing 102 secured to the outside ot the b 1 and by reference to these two figures a. well as to Fig. 1. it will be seen tl'iat the two handles 94 and 98 are c ose toget -r outside of the building so that he pi or the spout member 538 may be readily observed and controlled.

The operation and advantages of my invention will now be obvious. When the drum on which the cable a6 is wound is rotated in the proper direction, this cable will be pulled and the boom members 22 and 24- will be lifted around the pivot 28 as a center, thereby bodily lifting the spout members 3% and 38 around the pivot 36 as a center. hen the rotation of this drum is stopped, the be oms and spout members will be kept in the position into which they have been moved on account or" the wormv gearing acting as a stop. When this drum is rotated in the other direction to pay out the cable, the booms and spout members will swing down under the action of gravity. When the drum on which the cable as is wound is rotated in the proper direction, this cable will be pulled and the spout member 38 will be slid upwardly on the spout member 3a. hen the rotation of this drum is stopped, the spout member 38 will be kept in its upwardly telescoped position on account of the worm gearing acting as a stop. lVhen the rotation of this drum is reversed to pay out the cable, the spout member 38 will slide down on the spout member 3 1 by gravity. The shiilitable cable connection 4-0 permits the spout member 8G to slide in either direction while supported by the boom. By properly operating the two drums, the spout can be placed in any desired position for delivery ot material into the boat 0 other container. hen the spout is not in use, the cables at and i6 may be paid out so that the lower end of the spout member UK) will rest upon the dock and the boom may be swung around against the building on account of the swivel connection between the two sections of the goose neck.

I claim:

I loading spout device comprising two boom members having their inner ends socured together in angular relation in a vertical plane and pivotally supported for swinging movement in a vertical plane, an adjiiistable connection between the outer ends of said boom members, a spout pivoted at its upper end and consisting of telescoping members, a pulley carried by the lower end of said boom members, a cable passing around said pulley and having its two ends attached respectively to the upper and lower portion of the lower one of said telescoping members for supporting said member from said boom, power-operated mechanism whereby said boom members may be raised and lowered to vary the inclination of said spout, power operated mechanism whereby said spout may be more or less 'i'elescoped to vary its length, and means for independently controlling the operation 0t said mechanisms.

In, testimony whereof I hereunto atlix my signature.

HENRY G. ONSTAD.
