HOiSTING DEVICE.

Specification of Letters Patent. P t t d A g. 22, 1922.

Application filed Januarv 11, 1921. Serial m. 436,520.,

. of this application aims to provide a hoisting device for barrels having means whereby barrels may be hoisted to a point from where it is convenient to discharge the contents of the same, into a suitable receptacle without losing any of the liquid as the same is discharged from thebarrel.

'A further object of the invention is to provide a barrel, hoisting. apparatus having simple means whereby the barrel maybe tilted to a horizontal position upon being elevated. Y I t i 'A further object of, the invention is to provide abarrel hoisting device which .is simpleto operate, of highly simplified construction and cheap to manufacture.

Other objects and advantages of the, in. vention will be apparent during the course of the following description.

In the accompanying drawing, forming a part of this application and wherein like numerals are employed to designate like parts throughout the same,

Figure 1 is a side elevation of the -improved barrel hoisting apparatus.

Figure 2 is a front elevation of the same. Figure 3 is a horizontal transverse sectional view through a cradle embodied in the invention, the view being taken on line 3-3 of Figure 2.

Figure 4 is a detail sectional view illustrating a trunnion embodiedin the invention, the view being taken on line 1'4= of In the drawing wherein for thepurpose of illustration is shown a preferred embodiment of the invention, the numeral 10 generally designates the frame of the improved barrel hoistin apparatus, which frame includes upstanding spaced parallel sides 12 and 13. As illustrated in Figure 2 the upstanding .SitlQS 12 a d 3 a e spaced by means of cross rods 14 and15 which are secured tothe intermediate and lower portions offth'e sides 12 and 13. The metal from which the sides 12 and 13 are constructed mayfbe 7 v L-shaped or U shaped incross sectionso as to give the same the requisitestrength. The'lo'wer ends of the sides 12 and13 are connected by a transversely extending cross rod 16.

Withreference to Figurel will be if? served that the cross rods 14 15 and 1.6..are

located only at oneside of the frame so as to leave the other side of the frame entirely open to permit the barrel to be arranged between sides 12 and 13 without the necessity of lifting the barrels over the bracing devices. 7 j f The barrel B is adapted tobe seated in a cradle 20 which as illustratedlin Figure 2' includes longitudinally extending sides21 connected at their ends by means of spaced rods 22. One pair of spaced rods islocated at each end of the sides 21 and is'secur'edto the same by meansfof-,f astening ;devices;; .j

which may be in the form of bolts 24. it When one of the end members 22 lies in contact with the ground or other sup 'aorting surfacethe cradle 20 is in its lowermost position,

and the barrel is moved onto the lower end 22 sothatthe subsequent elevation of the cradle will result in the elevation of the barrel. With reference to Figure 1,,itiwill be noted that when the cradle is in a horizontal position, the barrel rests upon a pluralit-y of spaced parallel longitudinally curved strips 26 which approximately conform, tothe curvature of the barrel; H0118, I of the strips 26 is provided witha bolt 28 on which a clip- 30 is held by. means of a nut 81. The clip 30 which is carried by the bolt 28' is providediwith a bill adapted to engage one end of the barrel so as to securely connect thersame to the cradleq, When I the bill of the clip 30, isengaged with the;

barrel, the nut 31 may be tightened up so as to absolutely prevent the disconnection of the clip with the barrel.

The cradle 20 1s provlded intermediate its ends with a pair of laterally projecting trunnions generally designated by thenumeral 34 provided with eyes 36 slidable about tubular guides 37. The tubular guides 37 are two in number and are secured to the inner sides of the tra ns by means of bolts A-s illustratedin Figures 38 and 39. The bolts 39 extend through the tubular guide and through brace rods 40 connected to the branches of the sides 12 and 13. Each trunnion is provided with an attaching portion 4-2 which is extended through the tubular sides 21 of the cradle and held in position by means of a nut l3. lVhen the cradle laden with the barrel reaches the limit of its upward movement the same may be swung to a. horizontal position as illustrated in dotted lines in Figure It so that the contents of the barrel may be dispensed. The downward swinging movement of the cradle is limited by a transversely extending shaft 46 which constitutes a drum for a pair of flexible elements 47.

The flexible elements 47 are trained over.

pulleys 4-8 secured to' the upper ends of the sides 12' and '13. One end of each flexible element is rigidly secured to the drum 46 as indicated at 4:9 and the other end of each flexible element is secured to one of the trunnions 34;. By reason of this construction, the rotation of the drum 46 will result in the elevation of the barrel.

As illustrated in Figure 2, a spur gear 50 is mounted on one end portion of the drum 46 and is engaged by a smaller gear 51 mounted on an operating crank The spur gear and the drum may be held in a set position by means of a pawl 53 carried by the side 13 of the frame.

' In the use of the improved barrel hoisting apparatus, the barrel is positioned between the sides of the frame and upon the lower end 22 of the cradle. The clip 30 is now engaged with the upper end of: the barrel for securely connecting the barrel to the cradle. Upon the rotation of the crank 52, the cradle and'consequently the barrel will be elevated to a position illustrated in full lines in Figure 2'. Upon the elevation. of the barrel, the

cradle may be swung to a horizontal position as illustrated in dotted lines in Figure 1 and as previously stated the drum 4:6 constitutes a stop element for limiting the downward swinglng movement of the cradle. Of course when the cradle is elevated to the position illustrated in Figure 2, the pawl 53 may be engaged with the teeth of the spur gear 53 so as to hold. the drum in a set posi tionwhereby the cradle will be prevented from moving downwardly.

'VViththe barrel thus positioned horizontally as illustrated in dotted lines in Figure 1, the'contents of the barrel may be dispensed in the desired quantities. By reason of the fact that the barrel is elevated a considerable distance with relation to the ground, a bucket or' other receptacle may be located beneath the discharge end of the barrel to receive the contents of the same.

2 and 3, one end of the cradle is provided with lateral extensions which engage the tubular guides 37 so as to limit the swinging movement of the cradle in one direction. This prevents the cradle from being inverted or upset at an time.

f laving thus described the invention what is claimed is 1. An apparatus of the class described. comprising a frame inclusive of spaced par allel sides and means connecting the sides, a pair of upright guides secured to. the sides of said frame, a cradle having trunnions pro= vided with eyes slidable on said upright guides, pulleys connected to said sides, flex ible elements connected to said trunnions and trained over said pulleys, a drum carried by said frame and constituting a stop element for limiting the swinging movement of said cradle, said flexible elements being connected to said drum, an operating device for said drum, and means whereby said drum may be held in a set position.
