First Claim
1. In a machine for loading and conveying loose material such as rocks and the like:
- a. transport means for supporting and moving said machine on the ground,b. a machine frame carried by said transport means,c. material gathering means connected to the front portion of said frame,d. an elongated conveyor extending from the front to the rear of the machine,e. an apron disposed at the front of the machine and having a bed extending forwardly from above the front portion of said conveyor for transfer of material from said gathering means to said conveyor,f. means mounting the rear portion of said apron for pivotal movement about a transverse horizontal axis,g. means pivotally mounting the front portion of said conveyor to said apron,h. and means for vertically adjusting said apron so that the said front portion of said conveyor is simultaneously vertically adjusted.

Abstract
A loading and conveying machine has crawler treads and a frame extending forwardly thereof. A conveyor extends from the front to the rear of the machine. An apron is pivotally mounted at the front of the frame and receives material from a loading implement and deposits it onto the conveyor. The front end of the conveyor is pivotally mounted to the apron and arcuately moves about the apron pivot axis when the apron is raised or lowered. The joined conveyor and apron may also be adjusted together by vertically moving the apron pivot axis. The midsection of the conveyor is articulated so that the conveyor framework is separated into front and rear segments which are independently movable relative to each other and to the machine frame.
