Abstract
Abstract A reciprocating strand makes intermittent frictional driving contacting engagement with one or more rollers in a live-roller conveyor in one direction, and in the opposing or opposite direction, releasing means are provided to release said frictional driving engagement. The device is applicable for use with one or several driving means, and is adaptable for accumulation by releasing the frictional engagement by one or more sensing means, or trigger rollers, or other alternate sensing devices, which may be provided spaced along the conveyor bed. The actuating means of the present invention is furthermore adaptable for reverse travel of the handled material packages, as well as forward travel thereof, such reverse travel being initiated by suitable manually-operable switches, or other similar-type devices.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
169 words
In a live-roller conveyor of the type wherein articles to be conveyed are carried by a multiplicity of load-supporting rollers which are continuously rotated, the combination comprising: a. a plurality of load-carrying rollers; b. means for continuously rotating said plurality of loadcarrying rollers in one direction of rotation comprising: 1. a reciprocally-moving power device having reciprocal movement in two opposing directions one being a power-driving direction and the other a non-power-driving direction; 2. frictional means intermittently causing a frictional driving contacting engagement of said reciprocally-movable power device with said plurality of load-carrying rollers in said power-driving direction; 3. means effecting release of said frictional driving contacting engagement of the movable power device with the plurality of load-carrying rollers in said other non-powerdriving direction of said moving power device; and, 4. said power device repeating its frictional driving power stroke of said plurality of rollers in said one power-driving direction, whereby continuously rotation of the plurality of load-carrying rollers in the same rotative direction is provided in said power-driving direction.
Claim 2
Dependent Claim
169 words
In a live-roller conveyor of the type wherein articles to be conveyed are carried by a multiplicity of load-supporting rollers which are continuously rotated, the combination comprising: a. a plurality of load-carrying rollers; b. means for continuously rotating said plurality of loadcarrying rollers in one direction of rotation comprising: 1. a reciprocally-moving power device having reciprocal movement in two opposing directions one being a power-driving direction and the other a non-power-driving direction; 2. frictional means intermittently causing a frictional driving contacting engagement of said reciprocally-movable power device with said plurality of load-carrying rollers in said power-driving direction; 3. means effecting release of said frictional driving contacting engagement of the movable power device with the plurality of load-carrying rollers in said other non-powerdriving direction of said moving power device; and, 4. said power device repeating its frictional driving power stroke of said plurality of rollers in said one power-driving direction, whereby continuously rotation of the plurality of load-carrying rollers in the same rotative direction is provided in said power-driving direction.

Dependent Claim
31 words
means effecting release of said frictional driving contacting engagement of the movable power device with the plurality of load-carrying rollers in said other non-power-driving direction of said moving power device; and,
Claim 8
Dependent Claim
31 words
means effecting release of said frictional driving contacting engagement of the movable power device with the plurality of load-carrying rollers in said other non-power-driving direction of said moving power device; and,
Claim 9
Dependent Claim
39 words
said power device repeating its frictional driving power stroke of said plurality of rollers in said one power-driving direction, whereby continuously rotation of the plurality of load-carrying rollers in the same rotative direction is provided in said power-driving direction.
Claim 10
Dependent Claim
39 words
said power device repeating its frictional driving power stroke of said plurality of rollers in said one power-driving direction, whereby continuously rotation of the plurality of load-carrying rollers in the same rotative direction is provided in said power-driving direction.
