To Aill whom it may concern: Y j
Be it known that I, WTALTER ZETZMAN, a citizen of the United States, and a resident of Cornelius, in thecountyof Washington and State of Oregonyhafve invented a certain new 4and useful llmprovement in Hoisting and Conveying Apparatus, of which the following'is a specification; Y
The present invention relates to hoisting and conveying apparatus, and `has particular reference to a device adapted for use in barns, stables, andthelike, for transporting and distributing feed,fhay, andv other`ma` terial Vto feed boxes, and other parts of the building, and for various other uses.`
An object of the "present invention is to provide `a device of this character which is so constructed as to support a carrier box, and provide for the adjustment ofthe same in the various horizontal angles `beneath the carriage of the device.
The invention also embraces novel means for raising and lowering the carrier and retaining the same in elevated position while being conveyed.
'lhe above, and various other objects and advantages ofvthis .invention will be in part described and in partunderstood, from the following detailed description .of the present preferred embodiment, the same being illustrated in the accompanying drawing, wherein:
Figure 1 is a side elevation of a hoisting and conveying apparatus constructed according to the present invention.
Fig. 2 is an end elevation of the apparatus in `raised position. V- 0 Fig. 3 is a detail enlarged section taken longitudinally and substantially centrally through ythe i carrier and the mounted thereon,
Fig. 4 is a transversesection taken substantially `centrallythr'ough the same.
Referring to these drawings, wherein ylike parts are designated by similar characters of reference throughout the several views, 10 designates a double rail track, supported in any convenient manner upon hangers` 11 which are adapted for securement to the rafters, or other portions vof a building in which the apparatus `is `adapted to be employed. Q
A carriage `12 of hollow construction provided with outstandingweb'portions at its parts 'directly opposite ends carries upon said ends a pair 'nf `iupstanding parts or brackets 13 upon $pecication Letters Pat-ent.
the upper -of which are pivotall'y mounted rollersld for engagement `withthe opposed rails of the track 10. The carriage' 12 is preferably open at the oppositel ends and provided `intermediate its ends with a ratentea nee. a, inra.. applieationmed May 15,1917. serial No. massa downwardly extending hub portion' 151 i through which is vertically inovable'a pin 16 constituting a trip and bearing at its lower end against apair of inwardlyextendl ing lugs formed upon 'the upper pivoted ends of thegrip or jaw members 17, thelatter being mounted upon pins 18 carried upon the lower end ofthe hub 15.
A `horizontally swingingframe 19 is sup-` ported upon and arranged beneath the car rier 12, the same being 'substantially "U- shaped in cross section, and connected'to carrier 12 by a tubular bolt or connecting-mem` ber 20. lThe member 20 is providedat its upper end with an outstanding annular iiange, andV passes downwardly through openings formedin the adjacent abutting faces of the carriage 12 and the frame 19.
Anti-friction bearings 21 are interposed be` tween the lower face of the flange of said member 20, and the upper face of the bottom of the carriage 12. The lower end of the tubular member 20 is externally threaded and is provided with a pair 4of interlocking nuts or rings121, the upper one of which is adapted to engage the lowerface of the top wall of the frame 19. The jaws or grip members 17` are relatively lon and project downwardly through thetu ular member 20, and intof-the'frame 19. The frame 19 is thus mounted on the lower end of the tubular member20, and the latter'is freely rotatable inthe carriage 12 by the provision of'the ball bearings as jshown. that the carriage` `12 is provided with overhangingweb portions at its opposite ends formedby cutting away the sides1 to admit the uninterrupted turning ofthe frame-19 beneath the carriage.
The frame 19 is formed at opposite ends with bracket portions 22 in which are mounted for free rotation peripherally grooved rollers 23, and one of the brackets is providedwith a pair of spaced-apart outstanding -arms 24C between the outer vends of'which is mounted a drum 25. The drum 25 is keyed upon a shaft 26 which projects at one end beyond the adj acentbracket'arm 24, and which is provided with `afsproeket It will be noted* leo vit
A fall block 29v is arranged'beneath the frame 19, and is provided therein with a pair of grooved pulleys 30 adapted to receive'thereunder portions of a fall rope 31 which pass through the lower end of thev itis evident that'the fall rope 31 will be drawn over the pulley 23 and through the block 29 to raise the latter. The block 29 is'provided with an upstanding bail 33, having a shoulderedhe'ad 34 adapted for en-V gagement between-the lower beveled ends of the .jaws 17. The jaws 17 are adapted to swing inwardly toward each other by gravity, and to engage beneath the shoulder of the head .34s,.thus retaining the fall block in raised position beneaththe frame 19.
A clevisV 35 is pivotally and swivelly mounted upon the lower end of the fall block 29, and is connected, by means of a swivel eye36 to an outstanding strap or bail A37 carried upon a carrier box or other receptacle 38. The box 38 is elongated, is open at'one end, and is held from tilting by the provision of a strap 39 which is secured to the closed end of the box 38, and which extends to the clevis 35.V
The'track 10 is provided with a tripping block .t0 at any suitable point which lies in the path ofthe tripping pinl 16 and is adapted to depress the latter upon the movement of the carriage 12 over the track 10.
In operation, when the carrier 38 is lowered, the same may be filled to the desired `extent, with feed or other material to be distributed and conveyed, and the hand chain 28 is then actuated to rotate the drum 25 and wind the fall rope-31 over the same. As the fall rope 31 is wound upon the drum, the fall block 29 is raised in a position be-l neath the frame 19 and when drawn into its'uppermost position, the head 34 of the fall block engages with the`-jaws 17, setting the same apart, and the jaws interlock with the head' to hold the fall block in raised position. The carrier 12 may now be actuated either by gravity, or otherwise, to travel over the track 10 to the desired point of distribution. VWhen the carrier reaches `the point lof distribution, at which point,
the tripping block 40 is located, the block 10 strikes `the pin16 and depresses the same to spread apart the jaws 17 and thus release the fall block 29. The fall block 2 9 being thus released, is drawn downwardly by the weight of the material within the carrier boX 38. The fall rope 31 may be so adjusted as to limit the downward movement of the carrier 38. The hand chain 2S may also be actuated and controlled for lowering the box 38 to the desired position. A rake or other suitable device may be employed for withdrawing the contents of the box 38 when the latter is adjusted to the desired psition with respect to feed boxes and the It will be particularly noted that the frame 19 may be turned through substantially any angle'about the carriage 12 so as to dispose the handoperating chain 2S in any desired position, and the carrier 38, by virtue of its swivel connection with the fall block 29, may be turned to present its open end at any desired side of the apparatus.
It will also be noted that the apparatus comprises but relatively few parts, no springs are employed, and the means for locking the fall block 29 -in raised position is automatic, and positive.
Itis to be understood that various changes and modifications may be made in the details ofV construction of the above specifically described hoisting and conveying apparatus, without departing from the spirit of the invention, and being restricted only by the scope of the following claims.
I claim l. In hoisting and conveying apparatus, the combination of a carriage, a pin movable in the carriage, a pair of jaws suspended from the carriage and having portions engaging beneath the pin for supporting the same, a frame arranged beneath the casing, a fall rope in the frame, and a fall block mounted on the fall rope and adapted to be raised thereby into interlocking engagement .with said jaws, said pin being adapted to be depressed to spread said jaws and release the fall block.
