CARRIER OB OQNVEYEB;
Teal! wimp itpywgy concern:
Be it known that I, WILLIAM Kaiser inseam, a citizen ofthe United States, residing at Columbus, in the county of Franle lin and State of Ohio, have invented certain new and useful Improvements in Carriers or Gonveyers, of which the following is a specification, reference being had therein to t e accompanying drawing.
This invention relates to improvements in carrier or conveyer apparatus, it relating more especially to such mechanism when intended for use in distributing a mass of material over a wide area; as, for example, in forming piles of waste stuff such as culm or broken or ground rock and the refuse of mills.
Figure 1 is a plan view of a conveying and deliverin apparatus embodying my improvements. ig. 2 is a side elevation arts of the framework being in section. *ig. 3 is a detail view showing the pivotal mounting of the carrier frame. Fig. 4 is a cross sectional view of the carrier frame and shows the journal upon which it is mounted. Fig. 5 is a detail view showing engagement of the. carrier operating wheels, with the curved track.
The mechanism illustrated comprises as an entirety a portable structure 1 and a track structure 2, the latter having guide rails 3 supported upon cross ties or sleeper bars 4. Between the track rails 3 there is a rack rail 5 having ratchet teeth.
The machine shown is as a whole designed for use upon an inclined base such as the side of a slope or hill or pile of waste material, such as culm or sand or waste rock of the sort obtained in mining and in, reducing ores and the like.
The portable structure indicated by 1 comprises several frame elements secured to ether, one at the base being indicated by this conforming to the direction of travel of the machine, another at 8, which is at an angle to that at 7, and is adapted to support the adjustable part of the frame; a third at 9 adapted to support some of the power shafts and their wheels, and a fourth at 10 or b The base frame 7 is formed of longitudinal sill bars of suitable number which are joined together by cross glrts as shown at Specification of Letters Patent. Application niea November 29, megs. Serial n. 259,032.
desiglned to support the delivering carrier Patented Nov.-19, 1912.
1f3, 14, 15,16; From these there are uprights or standards as at 11, 12 for carrying .the frames 8 and 9. The cross bars of the base frame are extended laterally as shown at l5, 16 to support other parts of the structure.
The delivery apparatus proper is carried by the frame 10 and comprises longitudinal bars 17 with suitable cross connecting devices, together with truss posts 18 and truss rods 19 and 20. Upon this frame there can be supported (to attain some of the objects of the invention) any suitable carrier. I
prefer an endless carrying belt such as a rubber conveyer as shown at 21, which at the inner or lower end is mounted upon the drivin pulley 22 and at the I outer end upon t e idler guide pulley 23, there being a series of sets of troughing rolls at 24, 24 under the operative or outgoing part of the belt and a series of idler rollers 24 under the incoming or returning part.
The framework of this carrier is at points near the lower end mounted upon a turntable or pivot mechanism. This may be of any suitable character. At present I prefer one having the base support formed by the crossbars 15 which carry the upward rising pivot 26 to which there is fitted a journal 27 carried by the adjustable frame.
The weight of the upper part of the delivering carrier and its frame is taken upon standards or legs provided withwheels 28, 29. These are fitted to a curved track 35 which is supported upon the laterally projecting parts of the cross rails 15, 16 and upon the upper or forward end of the base structure 1. This track rail is shown as formed of a rolled channel arm bent to conform to the necessary curve. The wheels 28 and 29 are set with their axes inclined to each other so that they will properly follow thiscurved track. Power can be applied to either or both of these wheels to efi'ect the adjustment of the movable frame. As shown, there is a shaft 30 extending bacl ward along the-frame to the platform 38. At the front end of the shaft there is gearing 31, 32 by which the wheel 29 can be rotated, and when it is rotated the delivering carrier and its frame will be moved to one side or the other around the pivot at 26. Power can be a plied by an operator through the cranlcw eel or hand wheel at 33 and the shaft 30 can be against accidental rotation by means of the pawl and ratchet at 34.
To prevent the adjustable frame from be-' ing accidentally moved out of any desired position, as, for instance, by a wind of sufiicient force, the rail 35 is provided with a series of indentations, or apertures,.35", and with these pins or teeth 29 formed on or inserted into the periphery of thewheel 29 engage. Other devices equivalent to those just described can be employed. This together with the ratchet lock'at 34 insure the holding of the frame in any position after it has been ad'usted.
The carrier just escribed can be used as a distributing device for finally depositing material which is brought from some remote point. For instance, waste rock or culm may be brought from a relatively low point on carriers or belts such as shown at 36. The one'illustrated passes around the wheel 37 and returns over an idler wheel at 40. The material brought up by this carrier is delivered in the chute 38 which in turn directs it into a ho per 39 so arranged as to cause the materia to be deposited upon the belt 21. The chute 38 and the hopper 39 are so positioned with respect to the axis around which the adjustable frame turns that in whatever position the latter may have been put'it will'still receive the material from the carrier 36.
When it is desired to cause the entire apparatus to adv'ancealong the track structure 2 it can be done by the meansillustrated. At 41, 42 there are alternately actin pawls carried by eccentric devices on the shaft 43, each of these pawls being adapted to engage with the teeth on the rack 5. The eccentric carriers for the pawls are arranged with different radial relations totheir driving shaft so that when one is inactive the other will be active. This shaft 43 carries a gear wheel 45 44'which is driven by the pinion 45 on the shaft 46. On this shaft there are a loose belt wheel 4'7 and a rigid belt wheel 47". 48 is a belt adapted to engage with these and to be shifted fromone to the other and to be 50 driven. by the'belt wheel 48 on one of the shafts on frame 9. This shaft also carries,
the belt wheel 49 which receives power through the belt 50 from the motor or engine at 51, the latter being suitably mounted upon the base part of the frame. The operator 'shifts the belt 48 whenever it is desired to cause the advance of the apparatus as an entirety along the track.
The delivering and distributing conveyer 21 is driven as aforesaid by the roller or pulley 22 which receives its power through the geari 53-54. On the shaft of the wheel 53 is a belt pulley 55 which through a belt 56 receives power from the motor 57. The
latter is supported upon a platform 58 which carrier.
y The mechanism constructed in the way described can be operated in a manner which is obvious upon inspection of the drawings. A suflicient length ofthe track structure 2 is properly laid upon the inclined surface of the bed 6 which may be regarded as a pile of waste rock, culm, or the like. The apparatus for receiving, delivering and distributing the material is then put in position, as shown, and the primary carrier 36 set in operation. The material brought up by it is delivered to-the chute and hopper at 38, 39
and by these to the carrier 31 which carries it to and drops it over the drum or roller at 23. .When a sufiicient amount has been piled at a given point the operator by means of the hand wheeI 33 and the shaft 30 shifts to the right, and subsequently to the, left, the distributing carrier, until the material has filled up the available space. Then the operator shifts the power devices'so that the pawls 41, 42 are put in motionand the apparatus is forced up. the'track 5 far enough to provide suiiicient receiving space for a new series of operations.
It will be understood that the track-way 2 is constructed along the surface of the dump at such an angle that the curved track 35 is maintained in a substantially horizon tal position. The pin 26 will be vertical and the whole carrier frame can be swung with very little expenditure of power as it remains at the same level throughout its motion. 1
What I claim is:
1. In an upward inclined conveying and is secured to the frame 10 of the adjustable v carrying apparatus, the combination of a portable frame adapted to travel on inclined planes, a primary conveyer or carrier more or less supported upon the said frame, and
a laterally adjustable secondary carrier supported on said frame and arranged to receive material from the primary carrier and so supported that its outer or delivery end will swing in a horizontal plane, substantially as set forth. p
2. In a conveying or carrying apparatus,
the combination of a main frame having an,
inclined base element, a horizontally disposed element providing a horizontal guideway, a frame element 9 above the base element, transporting wheels on the base element, frame moving mechanism on the base element, a laterally adjustable conveyer frame having supports engaging said horizontal guideway, and a primary carrier partially supported on the elevated frame element 9, substantially as set forth.
3. In a conveying apparatus adapted to" travel on inclined planes, the combination of an inclined main frame, a supporting wheel mounted in the said frame near its rear end, an endless conveyer engaging with said said Wheel and bearing intermediate its ends 7 upon the said curved track, substantially as set forth.
In testimony whereof I aflix my signature, in presence of two Witnesses.
