A cradle .in'dicatedgenerallyj' at 21 is lpivotally mounted in the'supp'ortingframe' llllby means of a pivot mounting rod; .28".tra'nsversely,v disposed; and laterally,j;extend ed' from an end portion of the frame. .said pivotxrodhas.formed therein portions oilreduceddiameter 23 -and outer'grip' portions 3B. The portions of reduceddiameter V, are so spaced and of such width as to engage the sides. of... their front-lpostsrn when thepivotrod 12 8 ispositibired intthe :recepta'cles' l9 'ioniop'erationz.

Portions of a pivot rod 6'! of reduced diameter similar to portions 29 are clearly shown at 68 in Figures 6 and 8.

The outer end portions 38 provide convenient grips for positioning the pivot rod and cradle supported thereby at predetermined elevations in the receptacles I9.

The cradle 27 comprises longitudinal members 3 I, transverse drum rests 32 having upwardly disposed concave surfaces adapted to embrace drums or other articles to be supported and transverse stops 33 at the rear ends of said cradle. A finger 34 is secured to the drum stop, and is inwardly disposed to overlay drum rims and thus assist in maintaining said drums on the cradle.

A windlass means is indicated generally at 35 comprising an axle 36 rotatably mounted in the upwardly extended end portions of the posts II, a cylindrical reel 31, and a crank 38 for rotating the axle and reel at will. As clearly revealed in Figs. 1 and 2, the Windlass is preferably mounted in the frame in a position superposed. and spaced from the end of the cradle opposite the pivot mountin rod '28.

It is advantageous to be able to secure the Windlass means in adjusted position. To this end a ratchet wheel 39 is secured to the axle 31. A ratchet pawl 40 is pivotally mounted on the frame in in spaced relation to the ratchet wheel whereby said ratchet wheel may be engaged or disengaged by the pawl as desired to secure the Windlass means.

To convert rotational movement of the reel 3'! into elevational movement of one end of the cradle 21, cables 4| are secured at one end to sa d reel and at the other to the free end of the cradle as by means of studs 42.

Fig. 2 reveals elements of the hoist in end elevation for greater clarity. The flan es 26 on the handle means 23 are clearly revealed in a position overlapping the rear posts I i to en age the same upon upward movement of the handles.

A drum 43 having a spigot 44 is shown in in light line construction in a sup orted position on the cradle of the hoist and displaced from the horizontal, as for emptying purposes. The side elevation of the device of the present invention. as shown in Fig. 3, also reveals the handle means 23 in operating position.

Modified supporting frame A modified form of the present invention is illustrated in Fig. 4. For the front osts M in this modification, posts 45 of somewhat dissimilar construction are substituted. Said posts 45 are of box-like structure and have longitudinal openings 46 formed therein in commu ication with the hollow interiors of the same. The posts and openings comprise guide ways. Blocks 4! are slidably engaged within the box posts 45, as indicated in Fig. 5, maintained within said posts but freely positionable longitudinally thereof.

In this modified form. guide rod ill is substituted for the pivot rod 28. Said guide rod pivotally mounts the cradle 2! and abuts and is weldably secured to the slide blocks 41.

The posts 45 differ further from the posts l 2 in that they extend upwardly from the top stringer l6, as do rear posts I I, in order to provide greater freedom of movement of the cradle and supported objects.

A second Windlass means 59 is rotatably mounted in the upwardly extended end portions of the posts 45 in a substantially parallel relation to the first Windlass means 35. Said second windlass means 49 comprises an axle 50 rotatably mounted in said upper end portions of the posts 45, a reel 5| mounted thereon between said posts and a crank 52 for imparting rotation to the said axle and reel. A ratchet wheel 53 is secured to ,the Windlass means and a ratchet pawl 54 is pivotally mounted on the supporting frame in spaced It is frequently desirable to secure the drum in the cradle during the manipulating opera-- tions. To this end a modified cradle 5? somewhat similar to the cradle 2'! is illustrated in Figures 6, 7, and 8. The drums to be secured being of varying length, a securing means adjustable in relation to such length, is provided.

The modified cradle 51 has longitudinal members 58 somewhat similar to members 3! in the already described embodiment of the present invention. Members 58, however, are preferably constructed of channel-iron positioned on edge, said channel iron having a web portion 59 an upper lip portion 50 and a lower lip portion 6!. as shown in Fig. 8. The lower lip portion BI is serrated to provide ratchet teeth 62 as illustrated in Fig. 6.

The said longitudinal members 58 are secured in spaced relation to each other by means of drum rests 63 similar to drum rests already described. A drum stop 64, similar to stop 33, also already described, is secured transversely to the cradle at the rear end thereof. A finger 65 is mounted on the stop 64 and is directed inwardly relative to said cradle to overlay rims of supported drums and thus assist in securing said drum on the cradle. A tie piece 65 is secured to the longitudinal members 58 at the front end of the cradle to preclude spreading of the same.

A. pivot rod 61, somewhat similar to pivot rod 28. is employed to mount the cradle in the supporting frame as described. Said pivot rod 6'! also has portions of reduced diameter 68 for engaging receptacles in the supporting frame, such as l9.

An adjustably positioned framework 69 comprises a rear transverse strut element 10, a front transverse strut element H and runner elements 12. The rear strut 1D has an upper concave surface to permit said strut to slide under a drum supported in the cradle. The front strut H is notched, as at 13, to permit convenient access to the spigot of a supported drum. The struts are of such length as to hold the runner elements 72 in engagement with the channels of the longitudinal members 58 and yet not of such length as to cause said runners to bind therein.

Bolt elements 14 are provided to engage the ratchet teeth 62 and maintain the framework 59 in adjusted position. Said bolts comprise a beveled engaging portion 15, a body portion 16, and conveniently disposed thumb tabs 11. The body portions 16 of said bolts have formed therein longitudinal spring slots 18.

tibii pe mitting ttw' atid retcnet teeth The operation of a hoist constructed as described is as fdllb'tts:

The cradle 2'! is pivotally mounted in the suppdrtirfgfr'an'ie I at a selected heightby engaging the portions of reduced diameter '29 in selected receptacles f9? Thepajwllfl is released-ens the free end of said cradle lowered-a s far as possible. So'positioned the cradle is inatilted position as shown in Fig. 2 its rear,=-orfree, end resting at g early ground level, y

Drum 63 is positioned on the cradle by tipping the same awayfrdm the hoist; pas'sing the stop 33 under the bottom thereof, and then tilting the drum intothehoist to recline the same upon 'the barrel rests 32. The finger 34 then overlays the rim of the drum and assists in maintaining the same on the cradle.

The spigot 44, :being on the upper end of the barrel, is then in an exposed position at the front end of the hoist as shown in Fig. 3. If the spigot is not in the illustrated lower position, the drum may be conveniently rotated on the drum rests until in operating position.

The crank 38 is turned to rotate the Windlass means, roll the cables 4| on the reel thereof and thus e evate the rear end of the cradle. The pawl 40 is permitted to engage the ratchet wheel 39 when the cradle is in the desired attitude relative to said frame.

It is obvious that this provides a convenient displacing ocf the drum from the horizontal as for emptying purposes.

To move the hoist and supported drum, the handles 23 are extended as shown in Fig. 3 and the flanges 26 are caused to engage the posts H to permit the raising of the rear end of the hoist by lifting on the handles. Thus supported by the handles 23 and wheels 2|, said hoist and supported drum may be trundled about at will. When not in use the handles are folded down out of the way as shown in Fig. 1 and Fig. 4.

When the hoist is employed to raise an object such as a drum, as for loading the same on an elevated platform, the pivot rod 28 is preferably placed in receptacles I9 nearly adjacent, but

Operation .0 the cradle modification The modified cradle 51 is operated substantially as is the preferred embodiment of the same but with these added advantages. When it is desired to secure objects, such as drums, on the cradle the bolts 14 are retracted from engagement with the ratchet teeth 62 by pressing the thumb tabs 11 toward each other and the framework 69 is slid forward in the cradle a sufiicient distance to permit the drum to be loaded. The drum is positioned on the cradle 51 in the manner already described for cradle 21. The drum is then secured on the cradle by thrusting the framework 69 rearwardly causing the fingers B4 to overlay the top lip of the drum and finger B5 to overlay the lower lip thereof much in the manner of finger 34 already described. As the framework is thrust rearwardly the bolts i l ratchet rearwardly on the teeth 62 and oppose any forward movement of said framework when in adjusted position.

To release a drum so secured in position, the thumb tabs 11 are pressed inwardly to retract the bolts 14 and the framework is released from engagement.

Although I have herein shown and described my invention in what I have conceived to be the p aided cause-creme most practical and preferred embodiments, it is recognized that departures may be made therefrom within the scope of my invention, which is not to be limited to the details disclosed herein, but is to be accorded the full scope of the claims so as to embrace any and all equivalent devices and systems.
