PAPER-CONVEYING MECHANISM.

- T0 aZ-Z whom it may concern:

. Be it known that I, J Aims D. McCnAcKEN, a citizen of the United States, and residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Paper-Conveying Mephanism, of which the following specification is a full disclosure.

This invention relates to conveyor mecha-- nism .of the link belt type for suspendingly conveying sheetsof paper in varying quantities .frictionally gripped by self-gripp ng clamps constituting elements of the link belt. a

of the invention is to provide a An object Y paper clampin-gand supporting means which can be attached to and made a part of an endless link belt conveyor. 7

. Another object is to provide a gravlty actu'ated clamping means, the clamping action of the same being furthered through the medium of the weight and face friction of the suspended article or articles.

An additional object is to provlde a clamping means, detachably fastened to a single link, thus allowing for the removal or replacement ofthe said means without detaching the link from its companlon links.

Another object is to provide a clamp and carrier link designed to cooperate with guides suitably arranged to steady the clamp and carrier in its movement of translation and thus adapt it for supporting heavy loads.

Other objects and certain advantages will be set forth in the description of the drawings, forming a part of this specification, and reference is made to said drawings, in which:

Fig. 1 is a plan view of my unit clamp and carrier link.

Fig. 2 is a side elevation thereof.

Fig. 3 is an end elevation.

Fig. 4 is a bottom plan of the detached housing.

The numeral 1 designates a link of the detachable type, designed to form a part of an endless link belt conveyor, other links of which are shown in dot-and-dash lines at 2, Figs. 1 and 2. Any number of the herein described carrier units may be made to form a part of the endless conveyor chain, conformable tov installation requirements. No illustration of the endless belt and means of operating the same is made, inasmuch as the paper sheets or other material. swinging gravity actuated dog 20 is pivoted dius line Specification of Letters Intent.

signed to .carry clamping means automatically operable to hold a varying quantity or predetermined number of sheets of paper in suspended position. The housing 10 has a downwardly directed pl ate-like projection, or stationary jaw 11, one face 12 of which coacts with a swinging dog or jaw, 20, to clamp The as at '21, between the cars 22, of the rearwardlygand downwardly extending body portion of the housing 10. The outer curved surface 23, of the dog 20, is eccentric to the pivot 21, as indicated by dot-and-dash ra- The housing 10 is formed with stops 25,26, respectively limiting the upward and downward movements of the swinging dog 20, the same having suitably shaped abutments 25 and 26 for engagement with said stops.

Attached to the vertical side walls 30, of the housing 10, and extending horizontally and at right angles to the conveyor travel, are guide rollers 31, adapted to engage and rest upon suitable guide rails 32, the said rails and rollers acting to relieve the belt strain and to steady the carrier-units in their movement of translation.

As shown in the drawings, a number of sheets of paper orcardboard 40 are held in clamped carrying position, by their corners, although the sheets may be clamped at their edges as shown in dot-and-dash lines, Fig. 3. The weight and face friction of the sheets further the clamping action of the gravity actuated dog 20. The sheets are thrust upwardly between the face 12 of the projection 11. and the curved edge 23 of the dog, forcing the same upwardly against the face 12 and edge 23. hen the sheets are released, the surface friction of the same, combined with the action of gravity, causes the dog to wedge and securely hold the pack in suspended position. The sheets are thus held securely in position to be conveyed to a distant station.

In practise the carrier unit has been found to be a distinct and valuable improvement.

Having described the invention, I claim:

1. A unit carrier link, comprising a detachable link section, a housing detachably secured to said link section, and gravityactuated clamping means carried by said housing.

2. A unit carrier link comprising a link section, adapted to form a part of an endless chain belt, a housing detachably secured to said link section, and gravity-actuated clamping means carried by said housing.

3. A link of detachable link chain type, providing an integral attachment projection, a housing fastened to said projection, a clamping face upon said housing and a gravity-actuated eccentric clamping dog cooperable with said face to suspend sheet material therebetween.

4. A chain link of detachable type, a housing removably and dependingly secured to said link and an eccentric swinging clamping dog attached to said housing, adapted to cooperate with said housing to suspend sheets of material therefrom.

5. A chain link of detachable type, ahousing removably and depending'ly secured to said link, an eccentric swinging clamping dog attached to said housing, adapted to cooperate with said housing to suspend sheets of material therefrom, and means for limiting the movement of said dog in both directions.

6. A chain link of detachable type, a housing removably and dependingly secured to said link, an eccentric swinging clamping dog attached to said housing, adapted to cooperate with said housing to suspend sheets of material therefrom, means for limiting the movement of said dog in both directions, and cooperative track and roller means for steadying said housing during translative movement.

7. A chain link having a yoke frame providing a stationary jaw, paper receiving throat and bearing support for the swinging jaw, and an eccentric surfaced jaw pivotally mounted upon said frames within prescribed swinging limits and cooperating with said stationary jaw for frictionally clamping the sheets of paper therebetween.

In witness whereof, I hereunto subscribe my name, as attested by the two subscribing witnesses.
