.ASH-CAN-DUMPING APPARATUS.

Application led .Tune 5, 1926.

Our invention relates to improved apparatus to lift ash-cans and similar heavy containers and dump the contents thereof into trucks to be hauled away. One of its objects is to provide improved means to conveniently engage and lift the ash cans successively to a position where the contents of the cans may be dumped into the bed of a truck. Another object is to provide improved means adapted to conveniently dump the contents of the container into the bed of a truck. Another object is to provide lifting means adjustable to cans of different diameters. Another object is to provide an improved suspending apparatus adapted to be carried by the truck and to suspend the cans and swing them into position to be dumped and to swing them back to position to deposit the empty cans upon the ground. Our invention also comprises certain details of form and arrangement and combination of components, all of which will be fully set forth in the description of the accompanying drawings in which,

Fig. 1 is a diagrammatic view illustrating a hoisting apparatus mounted upon a truck and embodying our improvements.

Fig. 2 is a detail of the can supporting apparatus of Fig. 1.

Fig. 3 is a diagram illustrating the can supporting apparatus being lowered into position over a can preparatory to hoisting and dumping the can.

Fig.' 4 is a view similar to Fig. 3 illustrating the next stage in the operation of lifting and dumping the can.

Fig. 5 is a view similar to Figs. 3 and 4 illustrating the linal stages of dumping and returning the can to a vertical position.

Fig. 6 is a view similar to Fig. 2 illustrating a modification of the can supporting apparatus.

The accompanying drawings illustrate the preferred embodiments of our invention in which represents a truck body 16, the truck wheels drawn up in the street close to the curb 17 preparatory to lifting a series of ash cans, one of which 18 is illustrated in Fig. 1 as lifted a short distance from the sidewalk 19. In practice hotels, office buildings, .apartment buildings and similar build- Iings require at frequent intervals to remove considerable quantities of ashes, which is customarily done by moving them in large ash cans to the sidewalk where they are lifted and their contents dumped into a Serial No. 113,991.

truck and hauled away. This operation ol lifting the cans and dumping them requires two or more operators and puts a severe strain upon the operators, liable to cause injury thereto, in addition to being expensive.

Mounted upon the truck body is the pedestal 2O of a crane which in turn carries a crane arm 22 which is journaled by means of a series of conical rollers 24 constituting a step-bearing to the pedestal near the upper end of the pedestal and is provided with a stem or tubular shaft 25 projecting downwardly over the pedestal and provided at its lower end with an annular bearing 28 which takes the lateral thrust or strain of the lower end of said shaft 25 against the ei;- terior wall of the pedestal. rlhe crane arm 22 may thus be rotated relative to the pe'destal to lift the cans from the sidewalk, and swing them into position to dump the contents of the cans into the truck body. The crane arm is also mounted detachably by tapered dovetail joints 23 and adapted f" to be readily lifted from the truck and stored until again required for use. An eye is adjustably mounted near the free end of the crane arm. A bolt 29 serves to lock the stem 25 and arm 22 to the pedestal against rotation when desired.

Any type of block and tackle apparatus is adapted to be employed to lift the cans from the sidewalk anddum-p their contents into the truck. As illustrated a pair of

pulley blocks

30 and 31, and a chain or iiexi'blel cable 32 are employed, and the free end of the cable may be drawn over a friction or clutch wheel 33 and pawl 34 carried yby the crane arm adapted to grip the cable and hold the can in an elevated position during the dumping operation., and thereby provide for the cans being lifted and dumped by a single operator if desired.

The can supporting `and dumping apparatus comprises an upper yoke 40 'having an eye 41 by means of which it is suspended from the lower block 31., a lower yoke 42, and a ring 43. The ring 43 is provided on opposite sides with stud Ashafts o-r

trunnions

44 and 45 upon which the free ends of the yoke 42 and also the free ends ofthe yoke 40 journal. The ring 43 :may if desired be an unbroken ring, as illustrated in Figs. 3,

4 Iand 5, but is preferably constructed as illustrated in Figs. 1 and 2 or Fig. 6 of two parts, a-main ring section to which the lili)

ITX trunnions

44 and 45 are attached, and a gate section 5l hinged at 52 at one end to one ent of the section 50 and provided at its opposite end with a latch or with an eye to register with one or more similar' eyes 54 carried by the section 5() so as to be locked thereto by inserting a pin 4S through the

eyes

53 and 54 to lock the gate section 5l to the main section 50. In Figs. l and 2 we have also shown three screw rods 56 threaded through the ring sections 50 and 5l, and provided at their inner ends with shoes 5T adjustable to engage cans of different diameters, and at their outer ends with han-d wheels 58 by means of which said screws may be conveniently adjusted to diii'erent positions. In the modification of Fig. 6 we have shown a ring of rectangular pattern composed of the main section 59 providedL with trunnions 60 and 6l, and a gate tion 62 hinged to the main section 59 at (3S, and provided at its free end with an eye (S4 adapted to register with a pair of similai eyes 65 upon the section 59 andto be latched thereto by inserting a pin through the

eyes

64 and 65.

there cans of a single diameter are to be lifted the ring may be continuous and without the screws 56. To lift the cans the ring and yokes are lowered from the crane arm as indicated in Fig. 3 so that the ring 43 encircles the can and the lower yoke 42 is turned on the

trunnions

44 and 45 to pass downwardly ,along one side of the can. When the lower end of yoke 42 reaches the bottom of the can the can is tilted as indicated in Fig. 4 sufficiently for the lower end of the yoke 42 to enter and occupy a central position beneath the can while the ring supports the middle and upper portion of the can laterally.

The hoisting apparatus is then actuated to lift upon the yoke 40, and through the

trunnions

44 and 45 upon the yoke 42, thereby lifting the can from the sidewalk to a sufticient height where it can be swung upon the crane arm to any desired position ready to dump the can. The dumping operation is effected as indicated in Fig. 5 by turning the can, the ring, and the yoke 42 upon the

trunnions

44 and 45 with reference to the yoke 40 until the can is sutliciently inclined or inverted to dump or discharge its contents into the truck body, after which the can, ring and yoke 42 are restored to substantially the position shown in Fig. l and the can lowered to the sidewalk and the can released from the ring and yoke 42 by an operation substantially the reverse of that illustrated in Figs. 3 and 4. TWhere the diameters of the cans vary, the screws 56 may be einployed to support the cans of less diameter centrally with reference to the ring. Also where a number of cans are assembled in close relation the gate in the side of the ring may be opened to admit the can in place of lowering the ring down over the top et" the can.

The apparatus herein shown and described is capable of considerable modification within the scope of the claims without departing from the spirit of our invention.

lVhat we claim is:

l. A can hoisting apparatus comprisingl an upper yoke, a lower yoke and a ri` y' said `yokes and ring being pivotally relatively connected upon an axis common to both yokes and said ring to engage and hoist a can substantially as specified.

2. A. can hoisting apparatus coniprising a ring adapted to encircle a can and to laterally support the upper portion of the can, stud shafts extending outwardly from said ring upon opposite sides thereof, a yoke journaled at its free ends and supported upon said stud shafts and adapted to engage the bottom of the can to support the weight of the can, a yoke journaled at its free ends to said stud shafts and extending above said can and ring and adapted to support the weight of the can, ring and lower yoke through said stud shafts, said can ring and lower yoke being adapted to move with said stud shaft-s as a center of movement to discharge the contents of the can.

3. A can hoisting apparatus comprising an upper supporting yoke, a lower supporting yoke, and a ring composed of a main section and a gate section adapted to open and admit a can into said ring, said yokes and ring being pivotally relatively connected substantially as specified.

4. A can hoisting apparatus comprising an upper supporting yoke, a lower supporting yoke, ya ring, and radially adjustable shoes mounted upon said ring and :fulaptcd to be adjusted to support cans of (litter-ent diameters.

5. A can hoisting apparatus coii'iprising a suspending yoke, a ring pivotally suspended from the free ends of said yoke and adapted to laterally support the upper and middle portions of a can and a yoke depending from said ring and supported from said upper yoke upon the same axis as said ring to detachably engage the bottom of the can to lift the can.

In testimony whereof we have arlii-:ed our signatures.
