I As shown in Figs. 1, 6, and 7, the elevator The principal object of my present inven- 16 consists of a suitableframe and link belts tion is to provide an improved apparatus of 2021, carrying buckets 22, the link belts being the above general'description which will be supported upon sets of pulleys 23 24, respecso constructed as to require a minimum tively, mounted upon transverse shafts 25, as roc 5o amount of handling or moving, thereby avoidshown in Fig. 7. The belts 20 21 pass around ing the objections above pointed out and maksprocket-wheels 26 at the upper end of the elevator, as shown in Fig. 1, and are operated at the same rate of speed by the rotation of said sprocket-wheels through the instrumentality of a sprocket-wheel 27,which is mounted upon the same shaft. The latter sprocketwheel is connected by a chain or belt 28 to one of severalsprocket-Wheels mounted upon a shaft 29,earried by the scaffold 14, said shaft being driven from the shaft 11 of the crusher by a chain 30, which passes around the sprocket-wheel 12 and a sprocket-wheel 31, mounted upon the shaft 29. As shown in Fig. 1, the discharge-spout of the crusher is arranged to deliver the crushed material to the buckets 22 at the lower end of the elevator 16, in which it is carried up and discharged into wagons, cars, or other suitable receptacles.

As shown in Fig. 1, the upper end of the feed-conveyer 17 is suspended over the 110pper 9 of the crusher from a horizontal arm 32 of the scaffold and is arranged to discharge its load into the hopper. In order to properly direct the material into the hopper, a funnel 33 is provided, which is suspended from the conveyer-frame in such position as to receive all material from the conveyer and discharge it into the hopper 9.

For the purpose of permitting the lower end of the feed-conveyer to be swung laterally when desired it is pivotally secured at its upper end to a vertical shaft 84,;iournaled in bearings 35, secured to the arm 32, as shown in Fig. 2. A split collar 36, which is secured to side plates 37 38, extending from the conveyer-frame, embraces the shaft 34 and forms a bearing, which supports the conveyer and permits it to swing in a circular path.

The lower ends of the plates 37 38 are perforated and receive sleeves 39 40, respectively, which are connected to the side plates 41 42 ofthe feed-conveyer, as shown in Fig. 2, thus forming pivotal bearings for the upper end of the conveyer, permitting vertical adjustment of the lower end thereof.

43 indicates a drive-shaft for the feed-conveyer. This shaft is journaled in the upper portions of the side plates 41 42 and passes through the sleeves 39 40, so that vertical adjustment of the conveyer does not affect the position of the shaft 43 relatively to the shaft 34. The shaft 43 carries a sprocket-wheel 44 and a beveled gear 45, the latter being in mesh with a beveled gear 46, mounted upon the lower end of the shaft 34. The shaft 34 also has a beveled gear 47 at its upper end, which meshes with a beveled gear 48, mounted upon a horizontal shaft 49, carried by the arm 32 of the scaffold 14. The shaft 49 is driven from the shaft 29 by means of a sprocketchain 50, which passes around one of the sprocket wheels on the shaft 29, thence around guide-wheels 51 52, and around a sprocket-wheel 53, carried by the shaft 49.

By the construction described the shaft 43 may be driven from the crusher and the feed-conveyer may be adjusted vertically or laterally withoutinterfering with the drivinggear or stopping the machine.

As shown in Fig. 1, the feed-conveyer is preferably supported atits lower end upon suitable standards 54, and the conveying'device consists of a belt 55, carried by the conveyer-frame on suit-able rollers 56, journaled in the sides thereof, as shown in Fig. 4, said belt having on one surface a series of side plates 57 58, which are arranged near the opposite edges of the belt, as shown in Fig. 5. The plates 57 58 are connected in pairs, the plates of each pair being, however, disconnected from other pairs, but the several pairs of plates overlap successively or are shingled, by which construction the flexibility of the belt is fully retained and the material carried is prevented from spilling.

The side plates 57 58 are connected in pairs and to the belt by transversely-arranged U- shaped plates 59 (50 and intermediate bars 61, each pair of plates 59 60 being oppositely arranged at opposite sides of an intermediate bar 61, the latter bar being secured to the plates 59 60 and to the belt. The plates 59 (30 and bar 61 serve as buckets to carry the material thrown upon the belt.

62 63 indieateguide-boards, which are arranged at opposite sides of the feed-conveyer near its lower end, as shown in Figs. 1 and 4, and serve as ahopper to direct the material thrown upon the conveyer onto the belt.

As shown in Fig. 1, the feed conveyer frame is provided at its ends with rolls or pulleys 64, around which the belt 55 passes, and the belt is driven from the shaft 43 by means of a sprocket-chain 65, which passes around the wheel 44, and a wheel 66, mounted upon the shaft 67, which carries the upper pulley 64, and therefore for reasons already pointed out the feed-conveyer may be adjusted as desired without interfering with its operation or requiring adj ustment of the driving devices.

In practice the crusher is located conveniently to a supply of material, as gravel, which is then shoveled onto the lower part of the feed-conveyer and is by it conveyed through the funnel 33 to the crusher, from thence passing to the elevator and thence to a wagon or car. When the supply of material immediately adjacent to the feed-conveyer has been exhausted, the conveyer is shifted to a new position, and the work may thus be continued without moving the crusher or elevator until all the material has been removed from within an area proportional to the radius of operation of the feed-conveyer, when the apparatus may be shifted to a new position and the work continued.

That which I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination with supporting devices, of a feed-conveyer, the discharge end thereof being pivotally suspended from said supporting devices at a point beyond the conveyer proper in a manner to permit the re- IIO ceiving end of said conveyer to be adjusted vertically and laterally without aifecting the discharge, and a funnel suspended from the conveyer-frame and adapted" to receive the discharge from said conveyer, substantially as described; 7 v

2. The combination with supporting devices, of a'feed-conveyer, the discharge end thereof being pivotally suspended upon independent vertical and horizontal axes from said supporting devices at a point beyond the conveyer proper, in a manner to permit the receiving end of said conveyer to be adjusted vertically and laterally without affectingthe discharge end thereof,and a funnel suspended from the conveyer-frameand adapted to receive the discharge froln'said conveyer,.sulowhich it pivots, and means for driving said conveyer from the shaft 43, substantially as described.

'5. A conveyer-belt having at each side a series of overlapping side plates, and U- shaped plates connecting opposite side plates together and means connecting said 'U- shaped plates to the belt, substantially as described. I

.6. A conveyer-belt having at each side a series of side plates, and U -shaped plates connecting opposite side plates together and means connecting said U-shaped plates to the belt, substantially as described.

7. A co'nveyer-belt ha'ving at each side a series of overlapping side p1ates,and a pair of oppositely-arranged U-shaped plates connecting each pair of opposite side plates together and means connecting said U-shaped plates to the belt, substantially as described.

8. A conveyer-belt having at each side a series of side plates, a pair of U-shaped plates connecting each pair of opposite side plates together, and an intermediate bar between each pair of U-shaped plates and connected to the belt, substantially asdescribed.
