HORIZONTAL CONVEYER.

SPECIFICATION forming part of Letters Patent No. 708,698, dated September 9, 1902. Application filed January 8, 1901- Serial No. 42,533, (No model.)

The bracket 0 is attached at the wastebetween the buckets. 10o

By constructing the buckets in the manner shown the weight is distributed between the rails A A and the rail A, the major portion of the load, however, being carried by the two rails A A through the chain B; but in this manner I can construct a conveyer that can be traversed rapidly without the liability of tipping and one which can be readily tipped, however, when desired.

I will now describe the mechanism for discharging the bucket at any point throughout the length of the conveyer.

On each side of the conveyer, running parallel with the rails A A, are rails F F, made in the present instance of angle-bars. These rails F F are above the line of the rails A A, and in the present instance the rail F is directly above the rail A.

G is a metal frame suitably braced and having bearings g g on each side, in which are mounted the axles of the flanged wheels h h. The bearing-face of the rails is preferably on an incline, so that when the wheel 0 is traversed from the rail A to the rail F it will have a full bearing on said rail, and the rail F is preferably arranged to conform to the rail F.

On the frame G is a curved channel H,made, preferably, of a casting, having flanges 7L 7t and curved from a point y, Fig. 1, at the rail F to a point 11 over the line of the bucket D and back again to the point 1] at the rail F. The channel is of sufficient Width for the wheel 0 to travel in, as clearly shown in Fig. 4, and the curve is so proportioned that the bucket will be gradually tipped as the wheel 0 passes through the channel 1-1.

At each end of the rail F is a switch-rail F (Shown clearly in Figs. 1 and 2.) The switch-rail is pivoted at f to the rail F and is arranged to be turned down upon the rail A, and the rail F is such a distance above the rail A that when the switch-rails are raised, as shown in Fig. 2, the conveyer will travel under the rail F and the buckets will not be discharged; but if it is desired to discharge the buckets at this point the switch-rail is turned down, as shown by dotted lines in Fig. 2, and the wheels 0 of each bucket will be transferred from the rail A up the inclined switch-rail F upon the rail F, and as the curved channel-rail H is in line with the rail F the wheel 0 will be transferred from the rail F to the channel-rail H, and this channel-rail being curved, as described and shown, the movement of the wheel 0 along the channel-rail will gradually tip the bucket to the position shown in Fig. 45, so as to discharge its contents. By a continued movement of the conveyer the wheel passes from the channel to the rail F and from the rail F to the rail A, so that the bucket will assume its position again, as shown in Fig. 3. By raising the bucket to the rail F the bucket is in position to be more readily tipped at the curved channel-rail H, and this channel-rail can therefore be made abrupt, as it takes very little power to overbalance the bucket to discharge it.

By mounting the frame G, which carries the channel-rail II, on the Wheels h h the channel-rail can be moved to any point desired on the rails F F, so that if the conveyer is used to load material into bins the rails F F can be the length of the bins and the frame G can be moved along the bins to discharge the material carried by the buckets into any bin desired.

The above-described invention is of the same type as that described by me in an application for patent filed February 6, 1901, Serial No. 46,218, and in whichIhave broadly claimed a horizontal conveyer consisting of a chain with buckets or carriers and means for turning the buckets on the chain to any predetermined point.

By this invention I support the chain on suitable rails directly and support the buckets through the chains, the chains being simply an endless series of trucks, the inner end of each bucket, however, being supported on the guide-rail, and I provide a tipping means which can be moved to any point desired without discharging the buckets.

I claim as my invention- 1. The combination of a chain, a carrier therefor, buckets having one or more brackets pivoted to the chain, each bucket having a bottom extending from a point above the chain to one side thereof, a bracket secured to the inner end of the bucket, a wheel carried by the bucket, and a rail upon which the wheel travels, the outer end of the bucket being inclined and the inner end of the bucket being on the same incline as the outer end of the bucket, substantially as described.

2. The combination in an endless chain made up of a series of links, means for supporting the said chain, a series of buckets pivoted to the chain, a rail for supporting the bucket on one side of the chain, a second rail mounted above the first rail, a switch for transferring the bucket from the lower to the upper rail, and a discharge device for tipping the-bucket, substantially as described.

3. The combination of an endless chain, supports therefor, buckets pivoted to the chain, a wheel on the inner end of each bucket, a rail on which the wheel travels so as to support the bucket on one side of the chain, a movable discharge device consisting of a frame mounted on longitudinal rails, and a curved channel-rail, with means for transferring the wheel of each bucket from the supporting-rail to the curved channel-rail, substantially as described.

4. The combination of two rails arranged side by side, an endless chain B, brackets depending from the chain, wheels having their axles mounted in the brackets, said wheels arranged to travel on the rails, a series of buckets pivoted to the chain so as to swing laterally on the chain, brackets on the inner end of each bucket, a wheel carried by each bracket, a rail A upon which the Wheels travel so that the load is carried by the rails A and A, rails F and F, a frame mounted on the said rails F, F, a curved rail mounted on the frame, switch-rails for transferring the wheels from the rail A to the rail F, so that the wheels of the buckets will travel on the rails F, and on the curved rail to turn the buckets on their pivots and discharge the same, sub stantially as described.

5. The combination of an endless chain, a support therefor, buckets longitudinally pivoted on the chain, a rail supporting the inner end of each bucket, a rail mounted above the said supporting-rail, switch-rails for transferring the buckets from the supporting-rail to the upper rail, a frame longitudinally movable, and a channeled tipping-rail carried by the said frame and arranged to turn each bucket on the chain to the discharge position, substantially as described.

6. The combination of an endless chain made up of a series of links, wheels mounted on each link of the chain, two rails upon which the wheels travel, a bucket pivoted to each link of the chain, a wheel mounted on the inner end of each bucket, a rail upon which the wheel travels so that the load is supported by the three rails, rails parallel with the supporting-rails, a frame having wheels arranged to travel on the said rails, a curved tipping-rail carried by the frame,

switch-rails at each end of the rail directly above the single supporting-rail so that the wheels at the rear end of the buckets will travel first on the supporting-rail, then upon the rail directly above, the supporting-rail, and then upon the tipping-rail to the dis charge-point, causing the contents of the buckets to be discharged, and back again to the supporting-rails, substantially as described.

7. The combination of anendless chain made up of a series of links, a bucket pivoted to each link, each bucket having one or more brackets, bushings on the linksupon which the brackets are mounted, said bushings made in two parts coupled together, substantially as described.

8. The combination in an endless-chain couveyer, of a chain made up of a series of links pivoted together, the links being quadrangular in cross-section, a two-part bushing on each link, each part having a flange and a square opening adapted to the square link and means for coupling the parts together, a bucket, and a bracket on the bucket mounted on the bushing, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
