SPECIFICATION forming part of Letters Patent No. 760,524, dated May 24, 1904.

Application led January 26, 1903. Serial No. 140,643. (No model.)

To all wiz/0771, it may concern:

Be it known that I, ERNEST CRossLEY, a citizen ofthe United States, residing at Canton, in

the county of Stark and State of Ohio, have invented certain'new and useful Improvements in Conveyers,of which the following is a specilication, reference being had therein to the accompanying drawings.

Figure 1 is a side elevation of a portion of a conveying apparatus sufficient to illustrate the manner of applying my improvements. Fig. 2 is a plan View of the parts in Fig. 1. Fig. 3 is a perspective showing' one of the carrier-sections and a part of the guideway. Fig. 4 is a perspective of a part of one of the buckets looking' at it from the rear. Fig. 5 is a vertical section of the parts in Fig. 4.

A conveying apparatus constructed in accordance with my improvements may be loaded by any suitable mechanism. One of the uses to which it is applicable is the carrying of pigs after they have been cast from molten metal, and for purposes of illustration in the present case I have selected such an apparatus, and in the drawings it is indicated as so arranged as to deliver the pigs of metal to the conveyer.

A indicates a section of a rotary table or carrier of the sort used in vpig-casting machines, it having` a framework at B, upon which are supported a series of molds C, supported in such way that they can be inverted or turned for the purpose of discharging` the pigs therefrom. Not only in such an apparatus, but in others, it is frequently desirable that the conveyer should carry the loads of material first along' one level horizontally and then along another. For instance, depressed chambers, such as are indicated at E and adapted to hold bodies of water, can be used.

At F there is shown a substructure-*for inconstruction which constitute the characteristic matters of the present invention.

The sectlons of the carrler or conveyer are each as an entirety indicated by 1. As here illustrated, each of theseV sections has a hori- Zontal floor-like part 2 with side walls. The front end has an upwardly-turned wall 4, in which. are formed slots 4`for a purpose to be described.

6 is a bar to which the end wall is secured, the parts outside of the slot being held by hangers or suspension devices 5.

7 indicates a shaft extending across the carrier-section, or it may be formed as a gudgeen-like projection on the bar G. This shaft or the projection 7 carries the antifriction Wheels or rollers 8 for the upper part of the carrier-section. A chute-like plate or apron at 9 is provided, this being rigidly fastened to the front of the carrier section or bar 6 and extending forward to points near the rear end of the next adjacent carrier, this chute or wing being adapted to guide the pigs or other loads toward the next carrier-section.

rThe rear end of each carrier has supporting wheels or rollers 11, mounted on shafts or stud-axles 10.

The cars or carrier-sections are advanced by means of propelling-arms 1Q, which extend `downward from the rotary part B, each of these arms having a slotguideway l2, in which is litted the cross-bar 6 of one of the carriers and which permits the latter to be raised or lowered while advancing under the force imparted by the arms 12.

At 13 13 there are track-irons or supports and guides for the wheels or rollers 8, and at 14 14 there are corresponding guide-irons or tracks for carrying the wheels 11, these tracks or guides at 13 and 14 being shown as placed in the relatively higher levels of the path of the carriers. At 15 17 these tracks are respectively bent downward, the downwardlyinclined tracks extending therefrom to the lower tracks at 16 and 18 for the upper roll ers and lower rollers, respectively, of the cars or carrier-sections. At the place marked X, Fig. 1, the loading of the cars or carriersections can be regarded as being effected, some of the molds C being indicated by dotted lines as turning over at this point in any of the well-known ways. The loads that drop vthe carrier system, Erst descending over the inclined track-sections to the tracks 16 and 18 at the lower level and finally rising again to the tracks at 13 14 prior to the unloading.

The unloading of the cars or carrier-sections is effected by depressing or curving downward a part of the tracks or guides 14 at such points as are indicated by 19, the horizontal part of the depressed guides being shown at 20, and, if required, supports can be provided, as at 21. Vhile the lower wheels or rollers 11 are following this depressed part of the track the upper wheels or rollers 8 are by the upper track 13 held against lowering, and consequently the car or carrier-section attached to these pairs of rollers is gradually though rapidly tilted in such way as to permit its load to quickly slide therefrom. Afterward the rollers 8 are again brought to their g upper level on the guides 14, and the car or 1,

, tion of the series of carrier elements or seccarrier-section is ready for reloading.

Instead of a rigid ring-like driving-body,

such as a rotary table or frame at B, use may be made of a fiexible driver-as, for instance,

an endless chain or cable provided with suitable arms or projections analogous` to those at 12 andarranged in such way as to insure l the constant application of propelling power p to the cars or carrier-sections irrespective of the relative horizontal levels on which the latter may be traveling.

I am aware that tilting carrier-pans have been connected to endless chains and employed for the transporting of material from one point to another, where it is to be deposited, the pans in turn tilting at one end downward and being guided by downwardly-deflected tracks or guides; but in all cases within my knowledge the pans or conveyer-sections were each and all at some point'held in fixed position in relation to the driving-line of the chain, and guide-Wheels or idler-wheels or equivalent apparatus-for guiding the chain from one level to another were necessary in order to permit the pans or conveyer-sections to thus travel from one level to another.

It lwill be noticed that I employ supporting-tracks and pairs of wheels Vor rollers of different gages, the Wheels 8 8 and their tracks 13 and 16 being at a relatively greater distance apart, while the wheels 11 11 and their tracks y111 18 are relatively closer together. As a result I am enabled to always give a positive support to the car, pan, or carrier section at one of its ends and independent of the driving or propelling devices.v Thus the cars or sections are positively supported by the wheels 8 on the tracks 13 even when they are delivering their load downward. In those constructions having chain-drivers within my knowledge the pair of wheels which are held up when the pan or car is emptying are supported by the chains only, and consequently the size and weight of the carrier-sections are limited and strong and expensive chains are necessary, inasmuch as they must not only accomplish the propulsion but the vertical support of the carrier element.

What I claim is 1. In a conveying apparatus the combination of a driving device moving in relatively fixed lines, a series of carrier-sections movable bodily vertically from one set of lines of travel to another set of lines relatively to the driving device, and propelling devices interposedY betweenthe driver and the carrier-sections, substantially as set forth.

2. In a conveying apparatus, the combination with the driving or propelling device, of a series of carrier-sections receiving propelling power from the driver and adapted to bodily rise and fall in relation to the driver while being driven thereby, substantially as set forth.

3. In a conveying apparatus, the combinations, the driving device and the intermediate power-transmitting devices, the carrier-sections and the power-transmitters being adapted to rise and fall bodilyv in relation to each other. v'

11. In a conveying apparatus the combinationof the series of carrier-sections each adapted to have one part thereof rise and fall in relation to the other part thereof, the driving device and the intermediate power-transmitters, the carrier sections being adapted to rise and fall bodily in relation to the driver, substantially as set forth.

5. In a conveying system, the combination with the series of carrier-sections of the driving device moving in relatively fixed lines and the propelling arms or bars each adapted to engage with one of the carrier-sections at each of several points varying in their distances from the driving device, substantially as set forth. l

6. In a conveying system, the combination of the series of car-like carrier-sections each having a load-receiving receptacle and a sheetlike guide projected toward an adjacent carrier-section, and each adapted to have one of its ends tilt or rock about an axis adjacent to the other end, substantially as set forth.

7. In a conveyer system, the combination of the series of carrier-sections each adapted to be tilted, substantially as described, for emptying its contents, means for supporting the upper end of each carrier-section while tilting and a driving device for advancing the carrier-sections, said driving device being supported independently of the aforesaid supporting devices, substantially as set forth.

8. In a conveyer system, the combination of a series of carrier-sections, propelling mechanism therefor, supported independently thereof, two independent sets of guiding devices,
