Rivet-hinged belt fastener with teeth

A belt fastener for being riveted onto a transverse belt end, the combination comprising:

• upper and lower plates joined by arcuate hinge loops with the plates being attached onto upper and lower surfaces of the belt and the loops projecting beyond the belt end;
• pairs of rivet receiving apertures in the plates which are substantially vertically aligned with each other when the plates are on the respective belt surfaces;
• outer and inner edges of the plates with the inner edges extending generally parallel to the belt end and the rivet receiving apertures being spaced from each other across the plates substantially parallel to the plate inner edges;
• a pair of rivets for being inserted through the aligned pairs of rivet receiving apertures to attach the fastener plates onto the belt end;
• and
• teeth of the upper plate bent down from the upper plate about a bend line parallel to the upper plate inner edge, the teeth being on either side of the rivet receiving apertures in alignment across the upper plate with centers of the rivet receiving apertures to increase the holding strength of the teeth and riveted attachment of the fastener to the belt while minimizing the reachback distance between the inner edges of the plates at the end of the belt and the plate outer edges clamped onto the belt for travel over small diameter pulleys.

A belt fastener for splicing ends of belts together, the belt fastener comprising:

• an upper plate and a lower plate for being attached on opposite upper and lower surfaces of the belt at the end thereof, the plates including portions that are clamped into engagement with respective belt surfaces;
• apertures in the plates for being aligned to receive a fastener member through the apertures and the belt to clamp the portions of the plates onto the belt;
• and
• a window formed by a cut-out in the portion of the upper plate that is in engagement with the belt upper surface to allow for viewing of the belt upper surface and the end thereof along a line of sight from over the fastener through the cut-out window to determine if the belt end is properly aligned relative to the belt fastener before a fastener member is inserted through the plate apertures for attaching the belt fastener to the belt.

A hinged belt fastener for splicing ends of conveyor belts together, the belt fastener comprising:

• an upper plate and a lower plate for being attached on upper and lower surfaces of the belt at the end thereof, the upper and lower plates each including inner and outer edges;
• apertures in the plates for being aligned to receive a fastener member through the apertures and the belt to clamp the plates onto the belt;
• a pair of spaced loop portions extending arcuately from the inner edges of the upper and lower plates to interconnect the plates and defining a space therebetween rearward of the inner edges of the plates;
• and
• a window formed in the upper plate to provide a line of sight therethrough forwardly of the inner edge of the upper plate and distinct from a line of sight provided through the space between the loop portions to allow for viewing of the belt end from over the fastener to determine if the belt end is properly aligned relative to the belt fastener before a fastener member is inserted through the plate apertures for attaching the belt fastener to the belt.

• apertures in the plates for being aligned to receive a fastener member through the apertures and the belt to clamp the plates onto the belt;
• and
• a window formed in the upper plate to allow for viewing of the belt end from over the fastener to determine if the belt end is properly aligned relative to the belt fastener before a fastener member is inserted through the plate apertures for attaching the belt fastener to the belt;
• wherein with belt ends spliced together and being run on a conveyor system,
• a predetermined spacing of the belt end from the belt stop is provided for indicating potential splice failure with the window allowing said spacing to be visually observed during routine maintenance of the conveyor.

A hinged fastener for splicing transverse ends of belts together, the belt fastener comprising;

• upper and lower plates including aligned apertures in the plates for receiving fastener members therethrough and through the belt to clamp the fastener plates onto the belt;
• inner and outer edges of the plates with the inner edges extending substantially parallel to the end of the belt with the fastener attached onto the belt end;
• outer teeth on one of the plates extending towards the other plate substantially perpendicular to said one plate with the teeth having a pointed portion to pierce the belt and sink the teeth therein when the fastener is attached onto the belt end;
• and
• bend lines of the teeth adjacent to the apertures and extending parallel to the one plate inner edge with the teeth being bent down from the one plate outer edge about their bend lines so that the teeth face the belt end to keep the teeth in the belt from being pulled out from the belt with the teeth being adjacent the fastener members for maximizing the depth to which the teeth are sunk into the belt to increase the holding power of the riveted fastener against tensile forces applied thereto,
• wherein the apertures are generally circular in shape with the bend lines of the bent down teeth aligned along a line extending through the centers of the circular apertures parallel to the edges of the one plate.

A hinged fastener for splicing transverse ends of belts together, the belt fastener comprising;

• upper and lower plates including aligned apertures in the plates for receiving fastener members therethrough and through the belt to clamp the fastener plates onto the belt;
• inner and outer edges of the plates with the inner edges extending substantially parallel to the end of the belt with the fastener attached onto the belt end;

• and
• bend lines of the teeth adjacent to the apertures and extending parallel to the one plate inner edge with the teeth being bent down from the one plate outer edge about their bend lines so that the teeth face the belt end to keep the teeth in the belt from being pulled out from the belt with the teeth being adjacent the fastener members for maximizing the depth to which the teeth are sunk into the belt to increase the holding power of the riveted fastener against tensile forces applied thereto;
• wherein the outer edge of the one plate with the teeth includes a substantially straight portion that extends substantially parallel to the inner edge of the one plate;
• side edge portions extending obliquely relative to the one plate outer edge along and beyond the apertures so that the bent down teeth have an outer side that extends downward and inward for forming their point portions for piercing into the belt;
• the oblique side edge portions and the one plate outer edge meeting at opposite corners so that end tips of the point portions of the teeth reside at said corner before the teeth are bent from the outer edge of the plate;
• and
• a cut line extending substantially perpendicular to the outer edge from the corner at the outer edge inward to the bend line of the teeth adjacent the apertures for bending of the teeth from the plate so that the teeth have an inner side that extends substantially perpendicular to the plate.
