Abstract
Abstract An attachment device having a plate securable to a side of a scraper chain conveyor having outwardly projecting pins which pass through apertures in said plate. Disc elements are placed onto the pins to lie against the plate and a locking rod is passed through diametric bores in the pins at the side of the elements remote from the plate. The elements have wedge surfaces, preferably helical, on their faces adjacent the locking rod so that upon rotation of one or both discs the plate will be urged inwardly and axially of the pins and locked in position.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
112 words
An attachment device for scraper chain conveyors said device comprising: a. a plate having at least one aperture therein adapted to receive a pin projecting outwardly from a side of a scraper chain conveyor; b. a disc element adapted to receive said pin and lie adjacent an outerface of said plate; c. a locking rod adapted to pass through a diametric bore in said pin on the side of said disc element remote from said plate; and d. at least one wedge surface on a face of the disc element adjacent said locking rod adapted to urge the plate axially inwardly of said pin and effect clamping upon rotation about said pin.
Claim 2
Dependent Claim
112 words
An attachment device for scraper chain conveyors said device comprising: a. a plate having at least one aperture therein adapted to receive a pin projecting outwardly from a side of a scraper chain conveyor; b. a disc element adapted to receive said pin and lie adjacent an outerface of said plate; c. a locking rod adapted to pass through a diametric bore in said pin on the side of said disc element remote from said plate; and d. at least one wedge surface on a face of the disc element adjacent said locking rod adapted to urge the plate axially inwardly of said pin and effect clamping upon rotation about said pin.
Claim 3
Dependent Claim
104 words
In a scraper chain conveyor the combination of: a. pins projecting outwardly from one side of the conveyor, each pin haVing a diametric bore therein; b. an attachment plate having apertures through which said pins extend; c. a disc element received by each of said pins on a side of said plate remote from the conveyor; d. a locking rod extending through said diametric bores in said pins on faces of said disc elements remote from said plate; and e. wedge surfaces on said faces of said disc elements adapted to urge said plate inwardly of said pins upon rotation of said disc elements.
Claim 4
Dependent Claim
104 words
In a scraper chain conveyor the combination of: a. pins projecting outwardly from one side of the conveyor, each pin haVing a diametric bore therein; b. an attachment plate having apertures through which said pins extend; c. a disc element received by each of said pins on a side of said plate remote from the conveyor; d. a locking rod extending through said diametric bores in said pins on faces of said disc elements remote from said plate; and e. wedge surfaces on said faces of said disc elements adapted to urge said plate inwardly of said pins upon rotation of said disc elements.
Claim 5
Dependent Claim
21 words
A device according to claim 1, wherein the disc element is provided with two wedge surfaces arranged symmetrically of one another.
Claim 6
Dependent Claim
12 words
A device according to claim 3, wherein the wedge surfaces are helical.
Claim 7
Dependent Claim
19 words
A device according to claim 1, wherein the disc element has an extension projecting outwardly from its peripheral surface.
Claim 8
Dependent Claim
42 words
A device according to claim 1, wherein the attachment plate has two apertures each adapted to receive a pin, one disc element being provided for each pin, and the locking rod being adapted to pass through aligned diametric bores in the pins.
Claim 9
Dependent Claim
15 words
The combination of claim 2, wherein each disc element has two symmetrically-arranged helical wedge surfaces.
Claim 10
Dependent Claim
18 words
The combination of claim 2, wherein each disc element has an extension projecting outwardly from its peripheral surface.
Claim 11
Dependent Claim
35 words
The combination of claim 2, wherein a spacer piece is provided to define one or more chain passages at the side of the conveyor, said spacer piece having a continuation forming one of said pins.
