CARRIER.

Specicaton of Letters Patent.

Patented Apr. 9, 1912.

To @ZZ whom t may concern Be it known that I, GUNDER G. MANDT, a` citizen of the United lStates of America, and a resident of Vaterloo, Blackhawk county, Iowa, have invented certain new and useful: lmjiirovements in Carriers, of which the following is a specica-tion.

My invention relates to improvements in` carriers, and the object of my improvements is to provide a practical and convenient overhead rolling carrier for litter or other materials, adapted to be dumped automa-tically at a desiied location, and whose dump-4 ing-bucket may be elevated or lowered in use. This object I have accomplished by the means which are hereinafter described' and claimed, and which are illustrated in@ the accompanying` drawings, in which:

Figure 1 is a side elevation of the complete apparatus. F ig. 2is an end elevation of the dumping-bucket. Fig. 3 is an enlarged detail elevation of the spindle which carries .the ratchet wheel and windingdruin. Fig. 4 is an end elevation of the indented disk secured on the squared portioni of said spindle. Fig. 5 is anv end elevationI of the ratchet-wheel and resiliently controlled pawl, taken on a section of said spindie shown on the line a-Z) in Fig. 1.

Similar reference numerals designate corresponding parts throughout the several views.

The dumping-bucket 1 is suspended from a carriage comprising brackets 40 on an upright 30 containing the grooved wheels 38 adapted to ride upon a suspended overhead and 23 depend from the opposite ends of thev latter, being pivoted thereto on pintles 51 and 52, with

studs

53 and 54 on the bar 29` nearthe inner sides of said hangers to servel as stops therefor.

The rocking-beams 23y and 20l are pivoted together on a bolt 24` at a location intermediate between the lower endsof the said hangers. The left-hand end'of the rocking-body 20 is pivoted to the lower end ofthe hanger 27 by means of a pintle 44, while the rockingbody 23 is pivoted at a. point intermediate between its ends to the lower end of the hanger 28 on a pintle 45. A bearing pintle 46 is secured to the middle of the left-hand end of the bucket 1, and a hanger 22 connects said pint-le with the pintle 25 in the left-hand end of the rocking-body 23. On the opposite or right-hand end of said bucket in the saine relative location a bearing-pintle 42 is secured in a bearing-opening in that end by a nut 3 on its threaded end 2 and by bolts or rivets 47 as shown in Fig. 2,

passed through an integral disk 4. The intermediate portion of said pintle is squared at 41 to receive tixedly the hub 5 of a disk 6, the latter having an indentation or groove 43 on its circumferential edge. Adjacent to said hub, just outside, the lower end of the hanger 7 is pivotally mounted, the upper end of said hanger being pivotally connected with the right-hand end of the rocking-body 20 by a pintle 49. A windingdruin 11 and a ratchet-wheel 10 integra-l therewith on one side are rotatably mounted on the outer end of said spindle or pintle 42, the drum being provided with a crank 12, and the ratchet-wheel with a coacting pawl 9 controlled by a spring 8K to keep it engaged with the teeth of the wheel. The pawl is pivoted on a stud 26 projecting from the right-hand side of the hanger 7, and the upper end of said spring is secured to said hanger. A cable 21 is secured to and wound about said winding-druin 11, with its other end secured in the eye 4S in the right-hand endv of' the rocking-body 23.

A trip-lever 31 is inedially pivoted to the hanger 30k on a stud 34, and its upwardlydirected right-hand end 33 has its upper edge of convex form and located so as to engage and be pushed down vby a downwardly-directed convex stop 37 adjustably secured to the overhead wire or cable 35 by means of a thumb-screw or clamp-nut 36. The left-hand end of the lever 31 is provided with a plurality of longitudinally alined bearing-openings 32 adapted to adjustably singly receive pivotally the upper end of a depending link 50, the lower bent end of the latterbeing pivotally connected'to the end of a short crank on the left-hand end of a rockshaft 17 which is set to rock in bearingbrackets 18 and 19 projecting from the rocking-body 20. A link 16 is pivotally connected between a short crank on the right-hand end of the rock-shaft 17 and the upper end of a slidable detent 15, the latter movable vertically in alined bearing-orifices in brackets on a body 13 secured to the hanger 7. A

. coiled spring 14 secured to said detent and bearing against one of said brackets aids in retaining the point of the detent in the groove or indentation 43 in the edge of the disk 6, as well as to keep the above described parts shifted to retain the upper arm of the trip-lever 31 in its upper position ready to contact with the stop 37.

When it is desired to fill the bucket with litter or other materials it may be lowered sufficiently for the purpose by means of the winding-drum 11, whose rotation causes the cable 21 to unreeve aided by the weight of the bucket, and the swinging of the rockingbodies 23 and 20. The bucket is elevated by rotating the drum in a reverse direction. When the carriage 40 has been propelled along the overhead cable 35, the contact-end 33 of the trip-lever 31 contacts with the lower edge of the stop 37 and is forced down sufficiently to cause the connections to move to lift the detent 15, removing the point of the latter from the groove 43 in the disk 6. The bucket 1 then automatically turns and dumps itself in the receptacle placed thereunder.

It will be seen that the process of raising or lowering the bucket as well as dumping it at a desired location is efficient, that the clearance of the movable parts from the bucket opening is large and ample, and that the parts are of simple construction and easily accessible for use or repairs.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In combination, means of transportation l having depending pivoted hangers, rock-arms pivoted to each other between said hangers, one ofsaid rock-arms being pivoted to one hanger and the other rockarm to the other hanger, a tiltable bucket, a linking-connection between one of said rockarms and said bucket, a stud projecting from the opposite side of said bucket, an indented body fixed to said stud, a detent detachably engaging the indentation therein, means for yieldingly retaining said detent in said indentation, a linking-connection between said stud and the other rock-arm, and means adapted to move the first-mentioned rockarm to likewise shift the other rock-arm and raise or lower said bucket as desired.

2. In combination, a carriage, said carriage having a trip-lever pivoted thereto,

vrock-arins pivoted together and each separately pivotally connected to said carriage, a

tiltable bucket suspended from said rockarms by linking-connections on opposite sides thereof, engaging-means on said bucket, detachable connections between said trip-lever and said engaging-means adapted to release said bucket when the trip-lever is tripped, and means for shifting said rockarms to raise or lower said bucket.
