Abstract
Abstract An asphalt paving planer is illustrated wherein a power operated conveyor is mounted ahead of a cutter drum for receiving asphalt cuttings and conveying them to a truck and the like driving in the forward direction in front of the paver, and wherein a cutter drum drive is provided which includes an internal combustion engine for driving a V-belt drive which, in turn, drives a gear reducer carried adjacent the cutter drum.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
132 words
A self-propelled wheeled apparatus including a chassis for removing a thickness of asphalt paving and the like drivable in a forward direction comprising: a drum having spaced cutting elements thereon rotatably carried by said chassis extending below and in longitudinal alignment therewith; means carried by said chassis for driving said drum; a power operated conveyor having a charging point ahead of said drum in alignment therewith and adjacent thereto for receiving asphalt cuttings from said drum and the cutting elements carried thereby; means carrying said conveyor so as to extend upwardly and forwardly from said drum so as to discharge said cuttings into a truck moving forwardly in front of said wheeled apparatus; and a vertically adjustable scraper means carried adjacent said drum on a side of said drum opposite said conveyor.
Claim 2
Dependent Claim
132 words
A self-propelled wheeled apparatus including a chassis for removing a thickness of asphalt paving and the like drivable in a forward direction comprising: a drum having spaced cutting elements thereon rotatably carried by said chassis extending below and in longitudinal alignment therewith; means carried by said chassis for driving said drum; a power operated conveyor having a charging point ahead of said drum in alignment therewith and adjacent thereto for receiving asphalt cuttings from said drum and the cutting elements carried thereby; means carrying said conveyor so as to extend upwardly and forwardly from said drum so as to discharge said cuttings into a truck moving forwardly in front of said wheeled apparatus; and a vertically adjustable scraper means carried adjacent said drum on a side of said drum opposite said conveyor.
Claim 3
Dependent Claim
36 words
The structure set forth in claim 1 wherein means for driving said drum includes an internal combustion engine, a V-belt driven by said engine; and a gear reducer driven by said V-belt mounted in said drum.
Claim 4
Dependent Claim
44 words
The structure set forth in claims 1, or 2 wherein said means carrying said conveyor includes a connection adjacent a lower end of said conveyor permitting limited vertical and lateral movement, and means mounting the conveyor on said apparatus below its center of gravity.
Claim 5
Dependent Claim
92 words
A wheeled asphalt planer comprising: a frame; an internal combustion engine carried by an upper portion of said frame; a hollow cylindrical drum carried for rotation transversely of said frame below said motor; asphalt cutting elements spaced about said drum; a gear reducer mounted within said drum driving said drum; a V-belt drive transmitting power from said engine to said gear reducer; and a conveyor extending upwardly and forwardly of said drum in longitudinal alignment therewith for delivering material removed by said cutting elements to a vehicle driven forwardly of said planer.
Claim 6
Dependent Claim
92 words
A wheeled asphalt planer comprising: a frame; an internal combustion engine carried by an upper portion of said frame; a hollow cylindrical drum carried for rotation transversely of said frame below said motor; asphalt cutting elements spaced about said drum; a gear reducer mounted within said drum driving said drum; a V-belt drive transmitting power from said engine to said gear reducer; and a conveyor extending upwardly and forwardly of said drum in longitudinal alignment therewith for delivering material removed by said cutting elements to a vehicle driven forwardly of said planer.
Claim 7
Dependent Claim
16 words
The structure set forth in claim 4 including a scraper blade carried rearwardly of said drum.
Claim 8
Dependent Claim
25 words
The structure set forth in claim 5 including means mounting said conveyor for lateral adjustment with the lower end in substantial alignment with said drum.
