4 Claims.
1 This invention relates to dumpers and the object thereof is to provide a portable dumper comprisin a wheel-supported frame, a receptacle supported thereby upon lifting mechanism including means operable upon actuation of the lifting mechanism initially to raise the receptacle vertically while maintaining it in a substantially horizontal position to a desired predetermined height and upon continuation of the lifting mechanism so to tilt the receptacle as to discharge the material contained therein.
. One of the purposes of the invention is to provide a dumper having a receptacle adapted to be placed in a lowermost position while horizontal or in a somewhat elevated position where it can be most conveniently loaded for transportation and thereupon transported and raised to a higher position in which it can be automatically dumped into a bin or other container over a wall which is higher than the bottom of the receptacle when in transporting position.
Another object of the invention is to provide a dumper of the character described in which the receptacle is provided with means for supporting a table in horizontal positionand which can be utilized to transport articles upon the table itself or in which upon removal of the table articles may be placed in the receptacle, transported thereby and dumped by actuation of the lifting mechanism.
. An illustrative use of the invention is for the transportation of chases of type in which a table is placed upon the receptacle and can be used as a work bench upon which the type may be assembled and adjusted vertically to a height convenient to the operator and which can, after the assemblage of the chase, be transported to and positioned flush with the work table of a printing machine. Obviously the empty table can be positioned flush with the work table and the chase slid therefrom on to the table of the dumper and the assembled chase transferred to storage for future use.
As to a further use of the invention the table may be removed and the truck so positioned that when the chase is to be broken up the receptacle can be placed flush with the work table, the chase pulled over the edge of the receptacle, the dead metal dropped into the receptacle and the truck then transported to a melting pot, and the receptacle then tilted to dump the metal into the pot.
One of the features of the invention consists in providing the receptacle of the dumper with an end which is pivotally mounted at the bottom of the receptacle and so constructed as to form a chute which can be selectively locked in upright position to form a closure for the receptacle, or alternatively to be positioned in such manner that the chute will constitute a continuation of the bottom. By reason of such construction having receptacle lifting mechanism of the character above described the receptacle can be raised so that its bottom is flush or slightly above the edge of the type melting pot with the chute extending over and downwardly into the pot so that when the receptacle is tilted by the lifting mechanism the metal contained in the receptacle will flow gently into the pot without splashing.
By reason of this construction the present invention eliminates a great deal of type handling, it saves metal, as scraping of casts and slugs in handling is reduced to a minimum, and eliminates possible accidents which occur in old processes of breaking up of the metal in the chase, and either carrying or shoveling metal into the melting pot.
Obviously the invention is adapted to various other uses than that above described.
A further feature of the invention comprises providing a dumper having a rectangular receptacle provided with an end wall which is hinged at the end of the bottom and provided with wings adapted to lie closely to the sides of the receptacle when the end wall is in upright position forming a closure for the receptacle and when the end wall is positioned to form a continuation of the bottom to form sides of a chute which will prevent lateral spilling of the contents as it is discharged from the receptacle.
A further object of the invention is to provide manually controlled means for actuating the liftin mechanism which will enable the initial vertical movement of the receptacle while in horizontal position to be arrestedat any predetermined height.
These and other objects and features of the invention will more fully appear from the following description and the accompanying drawings and will be particularly pointed out in the claims.
A preferred embodiment of the invention is illustrated in the drawings, in which;

The front end portions of the side walls are connected by an axle 6 having wheels 1 mounted upon it. The triangular rear portions of the side walls have secured to them preferably by welding bases 8 to which are secured downwardly extending rotatable brackets 9 ofv casters Ill. The upper ends of the triangular portions of the side walls have secured to them a transverse handle II by means of which the dumper may be manipulated for transportation. A suitable receptable is supported upon the framework by lifting mechanism including an ticulated means connecting the receptacle to the side frames in such manner that upon actuation of the lifting mechanism thereceptacle will be raised vertically "in substantially horizontal position to the desired predetermined height and upon continuation of the lifting movement so tilted as to discharge the material from the receptacl'e. V
In the particular embodiment of the invention illustrated the receptacle is of rectangular form having parallel side walls 12 and I3, an inclined bottom l4, and a rear end wall I 5 which are welded together to constitute an integral construction. Preferably triangular brackets, which are welded to the bottom and extend downwardly in the planes of the respective side walls, comprise vertical members l6 and suitably inclined members H. The front wall 18 of the receptacle is secured to the upper ends of the brackets slightly below the end of the bott m by a hinge I9 so that the end 'wall l8fwhe'n in vertical position will form a closure for the receptacle and when in lowered position a continuation of the bottom M of the receptacle to form a chute.

which closely engage the side walls l2 and I3 of the receptacle.
Suitable means maybe provided for selectively locking the end wall I8 in closed position or in lowered position. As illustrated herein a suitable hook-shaped latch 2| is pivotally mounted upon the upper end or ends of the side walls and is adapted to be hooked over the upper edge of the front wall l8 when in closed osition. The
vertical members l6 of the triangular brackets andat their opposite ends are pivotally connected to the triangular upright portions of the frame. The upperand lower pairs of links 2 5 and 25 extend in approximate parallelism when the receptacle is in lowered position and the upper links 25 are of sufficiently greater length than Any suitable lifting means may be provided for raisin the receptacle. In the preferred construction an hydraulic lifting mechanism is provided which comprises a cylinder 26 which is pivotally connected upon the transverse girder 24 centrally of the width of the frame and the lifting head of the piston 21 thereof pivotally connected to a transverse bar 28 welded at its respective ends to the lower links 24, as illustrated herein. Obviously suitable means may be provided for connecting the lifting head of the hydraulic lifting mechanism to the upper pair of links as it is immaterial to which of the pairs of links the lifting force is applied.
The hydraulic lifting cylinder 26 communrcate's with a suitable pump 29 of a usual charaster, the piston rod 30 of which is connected by a suitable link 31 to an actuating lever 32, pref erably in the form of a pedal, which is fulcrumed upon a shaft 33 extending transversely of and welded to the side frames 1 and 2. The hydraulic cylinder 28 is provided with a usual relief valve which is controlled by a rod 34 suitably mounted in a cross member 35 connecting the side frames and operated by a screw threaded nut 36 Within the convenient reach of the operator.
In the preferred construction illustrated the upper edge portions of the side walls l2 and I 3 are provided respectively with parallel upwardly and laterally extending flanges 3'! which, as illustrated in Fig. 2, may be reversely curved to form a tubular reinforcement 38 as illustrated in Fig. 6. Such a construction comprises means for det'achably supporting a table 39 of the character and manipulation of chases of type, the table when supported upon the lifting mechanism described may be raised to a convenient height to enable a compositor to assemble the chase and the truck then transported to the printing machine and positioned at such height as to enable the chase to be slid upon the work table of the machine, or conversel to enable the chase to be slid from the work table on to the table of the truck and transported to a suitable storage place and again deposited in assembled order upon such storage support.
When it is desired'to destroy the type metal of the chase the table can be removed and the upper edge of the front end of the receptacle positioned flush with the work table, the chase gradually moved over the front end of the receptacle and spilled into the receptacle. The truck may then be transported to the, type metal melting mechanism the front end of the receptacle released from vertical position, and dropped to form a continuationof the bottom of the receptacle, and the receptacle sufficiently tilted as it is raised gradually to deliver thetype metal from the chute into the melting pot without splashing of the molten material therein. o
