30 Claims.

This invention pertains to a mechanism for handling containers such as barrels and the like and more particularly to a machine whereby the containers may be taken from one track or con- 5 veyor, automatically turned from one axial position to another and disposed upon a second track or conveyor in the axial position to which they are turned.

The machine to be disclosed herein has been practically applied and operated satisfactorily in connection with the handling of grease and oil barrels, so for convenience of reference as well as for the purpose of giving a better understanding of the invention, the invention will be disclosed in its application to a barrel handling system. Obviously, however, its usefulness is not so limited.

One of the principal objects of the invention is to provide mechanism whereby a container, disposed in one axial position such as a horizontal rolling axis position on a conveyor and carried therealong by the conveyor or by gravity or other means, may be turned from such posi-- tion automatically and automatically placed in 5 another position, such as on end, on a second conveyor by which the container may be carried away.

Another object is to provide a simple, cheap and eflicient arrangement of the character specified which may be operated in predetermined timed relationship to the time of receipt of the containers or in such manner as to predetermine spacing of containers on the conveyor for carrying the containers away after they have been turned, or both.

Many other objects, as well as the advantages and uses of the invention, should be or will become readily appreciated and understood after reading the following description and claims and 40 after viewing the drawings in which:

Suitable foundation members

2 and 3, receiving their support from the floor 5, support four standards 6, which are suitably interbraced and connected by framing members such as 7, 8, 9, 11 and 12. Pivotally mounted upon the front standards 6 at their upper ends on pivots 13 is a barrel receiving cradle or tipper comprising side members 14 interbraced by a shoe 15 at their front ends and by any suitable brace or spacer, if desired, at their rear ends. The cradle or tipper is adapted to be moved between its full line position and its dotted line position shown in Fig. 1 to turn a barrel received thereon in its horizontal or full line position through an angle of 90 about an axis at ,right angles to its rolling axis and place the barrel, when in such turned position, upon a conveyor upon which the barrel is carried away. The swinging of the cradle to up end the barrel is accomplished by mechanism to be described.

A prime mover, which may be the motor 16 mounted upon a suitable supporting bracket 1'7 carried by the frame of the machine, continuously drives the shaft 18 and the gear 19 through a chain of reducing gears, including the

gears

21, 22 and 23, all suitably carried upon the bracket 17. The gear 19 is loosely mounted upon a shaft 24 between a collar 25 pinned to the shaft 24 and a second collar 26 likewise pinned or keyed to the shaft 24. The shaft 24 is suitably mounted in bearings 27 carried upon the frame members 9 andupon its outer ends crank arms 28 are keyed or pinned in registering position. Pivotally connected to the outer end of each crank arm, as shown at 29, is a connecting rod 31, the upper end of which is provided with a head 32 which is slidably mounted upon and guided by a pair of rods 33, which are secured at one end to a block 34 pivoted as shown at 35 to the outer side of one of the longitudinal frame members 14 of the cradle. Springs 36 are interposed between the head 32 and the block 34 and springs 37 are interposed between the head 32 and suitable abutments such as nuts 38 on ends of the rods 33 to act as shock absorbers. As the crank arms are rotated the connecting rods are pushed upwardly and swing the cradle about its pivots 13 from the position shown in full lines to the position shown in dotted lines in Fig. 1 and then back again.

A clutch mechanism is provided for engaging and disengaging the source of power with the shaft 24. The gear 19 is provided with a boss 39 in the outer face of which and concentrically disposed with respect to the axis of the shaft 24 a plurality of recesses 41 are provided. One side of each recess may be beveled down as shown at 42. The collar 26 not only serves to retain the gear 19 in place, but also provides a brake drum, the surface of which is indicated at 43 and houses a clutch element 44, which is disposed within a recess in the collar and normally urged toward the boss 39 under the influence of a spring 45. A tooth 46 on the clutch element 44 is adapted to engage within any one of the recesses 41. I

A U shaped trip lever 47. disposed between the frame members 14 of the cradle and projecting into the path of a barrel when received thereon, is pivotally mounted as shown at.48, upon the rear standards 6. At its rear ends, the trip lever 47 is connected to the upper ends of springs 49, the other ends of which are connected as at 51 to a rigid portion of the frame-so that this trip lever is normally pulled in a counter clockwise direction by the springs. Forwardly of the pivots 48 the trip lever is pivotally connected as at 52 to a rod 53, the lower end-oi which is in turnpivotally connected, as at 54, to a clutchoperating rod 55 pivoted at 56 at the forward end of the frame member 9. The free end of the clutch rod 55 is provided with a clutch disengaging head 57, which has a knife edge enabling it, under certain conditions, to pass into a slot 56 in the underside of the clutch element 44, thereby to retract the tooth 46 from a. recess 41 to permit the gear 19 to idle on" the shaft 24.

1i brake band 59 encircles the breaking surface 43 of the collar 26 and is held in position by a brake rod 61 which may be rigi ly secured to the frame member 9 at the place at which the clutch rod 55 is pivotally connected. The brake band 59 is adjustable through the medium of a bolt 62, a spring 63 and a nut 64 so that any desired tension may be put upon the brake drum as may be required. The tension on the drum is constant in the embodiment of the invention illustrated and is preferably just suilicient to kill the momentum of the moving parts as the tipping cradle is returned to its initial position so that the cradle comes to rest in proper position to .receive' the next barrel. 4

Adjacent the receiving side of the tipping machine standards 65 support a track or conveyor,

the rails 66 of which are suitably, spaced so that barrels may be supported and rolled upon them.

In the present form of the invention the rails are inclined upwardly to and downwardly from a .55 p ak 67 so that each barrel designated as (shown in dotted lines in different positions in the several Jgures) is pushed up to and over the peak 67 by the barrels behind it. Owing to the downwardly inclined portion of the track between the peak 67 and the tipping mechanism, the barrel rolls down onto the cradle of the tipper under the influence of gravity but, quite obviously, positive mechanism for placing the barrels upon the tippercould be substituted for the, gravity track.

When the barrel rolls upon the cradle it-comes to rest thereon poationed by the'edges of the longitudinal frame members 14 of the cradle which, in the embodiment shown, are cut away as at 69 for curved sided barrels and guided and positioned by a rearwardly projecting tongue 71, preferably formed integral with the sho'e'15. The

barrel, due to its weight, depresses the lever 47' which depresses the connecting rod 53 and disengages the dog 57 from the clutch element, permittingthespring45tourgethetooth46toward the boss 39 and into one of the notches 41, when one comes into registration therewith, the inclined face 42 assisting in engaging the tooth in a notch. This action clutches the shaft, 24 to the gear 19, whereupon rotation of the shaft 24 swings the cradle about its pivot in a counter clockwise direction, viewing Fig. 1, through the intermediary of the crank arms 26, the connecting rods 31 and their associate mechanisms.

As the rear end of the cradleis swung upwardly, the barrel slides forward under-the influence of gravity and comes to rest on the cradle against a foot 72 which serves to hold the barrel, as well illustrated in Fig. 1, until the barrel is accepted by the conveyor which carries it away standing on end. This conveyor comprises a pair of chains 73 which carry over sprockets 74 either of which may be constantly or intermittently driven from a suitable sourceof power. ,If desired, the prime mover 16 may also be connected to drive the sprockets 74 or the conveyor chains 73. The chains 73 are supported and guided duringtheir travel by angles 75 suitably attached to the

supports

2 and 3 and are spacedsuiliciently far apart as to give clearance to the foot 72, which passes between them and below their top surfaces.

When the; mechanism and the barrel reach the positions illustrated in dotted lines in Fig. 1, the foot 72 is below the top surfaces of the chains of the chain conveyor or track and the barrel is transferred from the foot 72 to the chains which 'carry the barrel clear of the foot so that continued rotation of the shaft 24 may return the cradle to its initial position. Metal guides 75 extend along the sides of the supports 3 and preventthe barrels from moving on the conveyor chains as they are carried along.

The driving mechanism and the connections are so arranged that one complete revolution of thebull gear- 19 causes the cradle to move from.

its horizontal full line position to its substannotch 41 whereupon the brake 59 becomes effectivetogether with the inertia of the several parts to stop and hold the cradle in its horizontal position ready for the next barrel to be received thereon.

It should be appreciated that this mechanism greatly facilitates the handling of barrels and eliminates a considerable amoimt of manual labor which would otherwise be necessary. Furthermore, the :barrels may be moved onto the cradle in timed relationship. the'tipping machine may be set to operate in predetermined timed relation to receipt of barrels thereon and may be coordinated with the chain conveyorto dispose the barrels thereon in predetermined timed or spaced relation to one another. Conveyors of difi'erent types may also be substituted for the chain con-. 7

parts, the mechanism could be operated in the reverse manner, that is, the barrels could be. re-' ceived onto the cradle when the latter is in the position illustrated in dotted lines in Fig. 1 and the machine operated to raise the barrel to a horizontal rolling axis position in which position the barrel could be discharged onto a second conveyor.
