13 Claims, 9 Drawing Figures DRUM HANDLING DEVICE FIELD OF THE INVENTION Combined drum truck and drain rack of the type found in class 214.

BACKGROUND, SUMMARY AND ADVANTAGES OF THE INVENTION Hand operated drum trucks have previously been provided with gripping jaws operable to grip beneath and within the bead of a drum and lift the drum above the ground by tilting of the truck. One such truck is shown and described in US. Pat. No. 2,272,447, dated Feb. 10, 1942.

Such gripping devices as shown in US. Pat. No. 2,272,447 and in the Ericson et al. US. Pat. Nos. 2,698,107 and 2,814,403 have come into general use and have been very satisfactory, but are too complicated and expensive to be used on simple two-wheeled drum lifting and transporting trucks, and are not adapted for utilizing with a drum lifting and transporting truck which may also serve as a drain rack for the drum.

The device of the present invention is an improvement on the prior art drum lifting and transporting devices in that a simple form of two-wheeled drum truck is positionable by a telescopic handle and gripping jaws to lift and transport a drum, and is also positionable by the use of the handle into a drain position, to drain liq uid therefrom upon removal of the handle.

The advantages of the present invention are in the telescopic handle and in the simplicity and effectiveness of the gripping jaws for gripping and lifting the drum mounted on the handle in which the jaws may be released from the drum and the handle may be removed from the truck out of the way of the drain for the drum when the drum is in a drain position.

A further advantage of the present invention is that by the use of a movable handle carrying the gripping jaws, a two-wheeled truck may be used for lifting and transporting a drum and for positioning the drum into a position to accommodate the drainage of liquid from the drum.

Still another advantage of the invention is in the simplicity of the gripping mechanism carried by the handle coming into gripping engagement beneath and within the bead of the drum, by the simple operation of moving the handle along its socket towards the drum.

A further advantage of the invention is in the simplicity of the gripping jaws arranged to securely hold a heavy drum, and eliminating the complicated camming and leverage arrangements heretofore used for drum gripping devices.

Other objects, features and advantages of the invention will be readily apparent from the following description of certain preferred embodiments thereof, taken in conjunction with the accompanying drawings, although variations and modifications may be effected without departing from the spirit and scope of the novel concepts of the disclosure.

DESCRIPTION OF PREFERRED EMBODIMENTS OF INVENTION In FIG. 1 of the drawings, we have shown a drum truck and drain rack 10, constructed in accordance with the principles of the present invention including a truck frame having a pair of parallel spaced frame members 11 connected together at their rear ends by a cross frame member 12 and at their forward ends by a cradle 13 generally V-shaped in form and diverging toward the center of the cradle. The cradle 13 has rollers l5 journalled thereon rotatable about an axis of a drum l6 and having supporting engagement with the drum, accommodating rotatable movement of the drum with respect thereto.

A cradle bar 17 extends rearwardly along the truck from the center of the cradle 13 at an angle with respect to the side frame members 11, shown in FIG. 1 as being upwardly inclined relative to the ground when the truck is in a drum transporting position, said cradle bar 17 has cradle arms 19 extending angularly upwardly from opposite sides thereof forming'supports for rollers 20 rotatable about axes in alignment with the axes of rotation of the rollers 15 and having supporting engagement with the drum 16 in spaced relation with respect to the rollers 15, to support said drum for turning movement to position a drain opening 21 of said drum into a drain position when the frame 11 is tilted into the drain position shown in FIG. 2, as will hereinafter more clearly appear as this specification proceeds.

The frame 11 is supported on wheels 22, which may have hard rubber tires 23. The wheels are journalled on a transverse shaft 25 mounted at its ends in bosses 26 depending from the bottom of the frame members 11. The cradle bar 17 is hollow and is shown as being generally rectangular in form, although it need not necessarily be rectangular, and is braced to the side frame members 11 by braces 27 extending from the insides of the frame members 11 angularly toward each other and converging to opposite sides of the cradle bar 17 and welded or otherwise secured to said cradle bar, and to the frame members 11. The cradle bar 17 has a support leg 29 pivoted between ears 30 depending from the bottom of said cradle bar and disposed adjacent the cradle arms 19 and forming a support for said cradle bar, supporting said cradle bar and the

cradles

13 and 19 and rollers and 20, respectively in the drain position shown in FIG. 2, upon tilting of the frame 11 to be supported on the rear ends of the side frame members 11 and said support leg. When the truck is tilted into a drain position, a handle 31 therefor is removed and the drum is turned with its drain opening 21 at the low part of the drum. A spigot (not shown) may then be secured to the drain opening of the drum to accommodate ready draining of the contents thereof.

Referring now in particular to the handle 31, which will hereinafter be termed a slip fit handle, said handle is shown as slidably carried in the cradle bar 17, and as being generally rectangular in cross section, to gener ally conform to a hollow interior portion 32 of the hollow cradle bar 17. The slip fit handle 31 has an enlarged shouldered portions 33 engaging the end of the cradle bar 17 when in the innermost position of said handle with respect to said cradle bar. The outer end portion of the slip handle 31 has a handle bar 35 secured thereto as by welding or other securing means and forming a gripping means for the hands of the operator of the drum truck.- I

Disposed above the shouldered stops 33 of the slip handle 31 are a pair of parallel spaced stationary ears 36, extending outwardly from said handle over the head of a drum 16. Said ears each have a stationary clamping jaw 37 depending therefrom, in position to extend within a bead 39 of the drum 16 when the rollers 15 and of the

cradles

13 and 19 are in engagement with the cylindrical side wall of the drum.

Pivoted between the ears 36 adjacent the upper end thereof on a pivot pin 40, the axis of which extends inwardly of the bead of the drum 16 over the head of the drum, is an ear 41 extending outwardly of an elongated clamping jaw 43 intermediate the ends of said bar. A stop 42 positions the clamping jaw 43 to come into engagement with the top of the bead 39 of the drum upon downward movement of the slip handle 31. Said clamping jaw is biased into engagement with said stop by a tension spring 44 connected at one end to the slip handle 31 on a connector 45 and at its opposite end to the clamping jaw 43 on a connector 46. a

The clamping jaw 43 is in the form of an elongated bar having a bottom camming surface 47 inclined downwardly from its outer to its inner end at a relatively slight camming angle, to be forced outwardly against the spring 44 as forced into engagement with the bead of the drum upon telescopic movement of the slip handle 31 within the cradle bar 17. The jaw 43 has a lower recessed portion 48 facing the bead of the drum 16, the lower end of which is defined by a lip 49 extending thereacross above the camming surface 47. The recessed portion 48 converges from the inner margin of the lip 49 to the plane of the bar along a uniform elongated curve of sufficient length and curvature to accommodate the stationary jaw 37 to be moved downwardly within the bead of the drum to the drum head.

The spring 44 will then engage the lip or gib 49 beneath the bead of the drum, and thereby effect lifting of the drum and holding the drum to the

rollers

15 and 20 of the respective cradles l3 and 19, as the cradle bar 17 is tilted into a carrying position, to accommodate moving of the truck and drum along the ground from place to place, by an operator gripping the handle bar 35 with the hands.

FIGS. 4, 5, 6 and 7 illustrate the sequence of operation of the gripping

jaws

37 and 43 to grip within and beneath the bead of the drum to effect lifting thereof upon downward sliding movement of the slip handle and tilting of the lift truck about the axes of the wheels 22. In FIG. 4, the telescopic handle 31 has been'inserted in the hollow interior portion 32 of the cradle bar 17 and the

rollers

15 and 20 of the

respective cradles

13 and 19 have been engaged with the peripheral surface of the drum. The handle 31 is then moved downwardly to engage the inclined camming undersurface 47 of the jaw 43 with the bead of the drum. and effect camming movement of the jaw 43 outwardly to pass along the outside of the bead of the drum. As the jaw 43 moves downwardly along the outside of the bead of the drum into the position shown in FIG. 6, the

jaws

37 and 43 are in position to have clamping engagement with the drum. The truck is then tilted about the axes of the wheels by the handle bar 35 and slip handle 31 to lift the bottom of the drum above the ground. Continued movement of the slip handle 31 downwardly along the hollow interior portion 32 of the cradle bar 17 will bring the shoulders 33 into engagement with the top of the cradle bar 17. The gripping action is attained by the weight of the drum on the lip 49 and the tension spring 44 closing the

jaws

37 and 43 to grippingly engage within and beneath the bead of the drum as the drum slides downwardly along the cradle bar and rollers l5 and 20 on the respective cradles. The drum may then be transported from place to place and deposited in an upright position for storage or may be placed in the drain position shown in FIG. 2 for draining the con tents of said drum as the drum is turned to position the drain 21 in the drum head in the low portion of the drum.

In FIGS. 8 and 9, we have shown a modified form of clamping jaw arrangement from that shown in FIGS. 1 through 7. In this form of clamping jaw arrangement, an ear 50 is welded or otherwise secured to the slip handle 31 and has a downwardly and inwardly extending jaw 51 engageable within the bead of a drum. Jaws 53 are pivotally connected to opposite sides of the ear 50 adjacent the outer end thereof on a transverse pivot pin 54. The jaws 53 extend downwardly and inwardly of the pivot pin 54 along the outsides of the slip handle 31 and have an outwardly hooked lower end portion 55, the undersurface of which forms a curved camming surface 56 camming the jaws 53 to the outside of the bead of the drum as the slip handle 31 is moved downwardly, and accommodating said jaws to come beneath the bead of the drum as the slip handle 31 is lowered along the cradle bar 17, and to come into clamping engagement with the bead of the drum as the truck and cradle bar are tilted and continued pushing on the slip handle causes the drum to slide downwardly along the

rollers

15 and 20 of the

respective cradles

13 and 19. A tension spring 57 is connected between the slip handle 31 and the outer end portion of a handle 59 for the jaws 53. The handle 59 extends from the clamping jaws 53 and is welded or otherwise secured thereto on the opposite side of the pivot pin 54 from hooked portions of said jaws. The tension spring is provided to bring the clamping surfaces of the jaws 53 beneath the bead of the drum and come into position to lift and hold the drum to the truck as the slip handle 31 is moved downwardly to engage the shouldered portion or collar 33 with the end of the cradle bar 17.

It may be. seen from the foregoing that a simplified form of drum truck has been provided which when carrying the drum is tilted in one direction, and which may be converted to a drain rack by tilting in an opposite direction, and removing the slip handle and supporting the end of the rack adjacent the leg 29 on said leg and on the rear ends of the frame members 11, and then turning the drum on the rollers and until its drain opening 21 is at the lower part of the drum, as shown in FIG. 2.
