BELT OR LIKE CONVEYER.

SPECIFICATION forming part of Letters Patent No. 739,884, dated September 29, 1903.

I Application filed November 3, 1902. Serial No. 129,896. (No model.)

plication in Great Britain, No. 18,802, bearing date August 27, 1902,) of which the following is a specification.

This invention consists of improvements relating to belt and like conveyers, whereby the said appliances are'made conveniently portable and adapted for ready erection in various places in mines or underground workings and for other services.

Referring to the accompanying sheet of explanatory drawings, Figure l is a sectional elevation representing a belt conveyer con-. structed in accordance with this invention as erected in position in a mine-stope for the removal of rock or other material after the completion of blasting operations. Fig. 2 is a sectional end elevation through the line a. a, Fig. 1, while Figs. 3 and 4 are similar views through the lines I) b and c 0', respectively. Figs. 5 and6 are detail views to a larger scale, respectively showing the upper or extensible portion of one of the standards for supporting the intermediate pulleys and the method of clipping the adjustable bracket to the standard.

The same reference-letters in the different views indicate the same parts.

A conveyer constructed in accordance with this invention comprises an endless moving belt or flexible carrier, as A, adapted for the reception and transit of the material, terminal drums B B, and guide or belt-supporting pulleys, as C, disposed at intervals between the said drums. The respective guide or beltsupporting pulleys aforesaid are arranged in groups, and each group (one of which is shown at Fig. 3) is arranged upon a bracket, as O, adjustably secured by bolts or other fastenings to stretcher bars or standards, as D,which preferably, by means of packing-pieces with Wedges, as E, and screwed extension-pieces F, can be very readily and firmly fixed between the roof and the floor or between the walls or sides of the stopes or drives. The brackets C, holding the aforesaid groups of idly-running guide-pulleys C for the support of the upper or operative portion of the belt or carrier and also to prevent the lower or returning portion from trailing on the ground,

can also be carried upon wire ropes stretched beneath or above, or both beneath and above,

the conveyer-belt 0r carrier A.

The terminal drums can be carried by stretcher bars or standards similar to those aforesaid or be anchored to the ground. The shafts or spindles on which the said terminal drums revolve may be held rigidly in position, but they are preferably mounted in swivel-frames, such as illustrated at Fig. 2, so that they may the more readily adjust themselves to the precise position in which they are required to run.

The rotation of the terminal drums, or of one of them, to give the required movement to the endless conveyer-belt is effected by manual or other power in any convenient manner.

The material to be conveyed is preferably placed on the upper portion of the belt at any point between the terminal drums for conveyance to one or the other of the said drums, where it is automatically dumped or discharged onto a bin or chute, as G, which delivers it into a wagon, as H, or some-other receptacle.

The aforesaid apparatus can be very readily and conveniently set up in various parts of a mine, and by the use of the same a great saving in labor is effected over the existinghand shoveling and raking operations in stope and like workings.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In combination with a flexible carrier, terminal drums, intermediate pulleys and extensible standards to extend from the floor to the roof of the mine or underground working, said standards carrying the said intermediate pulleys, substantially as described.

2. In portable conveyers, the combination with a flexible carrier, of terminal drums, groups of idly-running pulleys, brackets or holders for the said pulleys, standards to which the said holders are adjustably se- 1 spectively and detachablysecured, and means cured, and means consisting of wedges and for the temporary fixing of the said supports extension-pieces whereby the said standards in various positions for service, substantially are fixed in position, substantially as deas described and as illustrated. scribed and as illustrated. In witness whereof we have hereunto set our 3.
