LINK FOR CONVEYER-CHAINS.

Specification of Letters Patent.

Patented May 16, 1911.

Application filed June 21, 1910. Serial No. 568,209.

To all whom it may concern:

Be it known that 1, PETER IGRIOKSON, a

citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented a new and useful Link for Conveyer-Chains, of which the following is a specification.

The link which is the subject of the present invention is designed primarily for conveyer chains handling lumber, and it is the object of the invention to provide an improved form of link for a conveyer of this kind, by means of which the lumber will readily pass onto the conveyor, and is effectually prevented from stopping if it encounters trash and other obstructions.

With this object in view, the invention consists in a novel construction and arrangement of parts to be hereinafter described and claimed.

The invention is illustrated in the accompanying drawing forming a part of this specification, in which drawing Figure 1 is a plan view of a fragment of a conveyor chain showing one of my improved links. Fig. 2 is a longitudinal section of the links, and Fig. 3 is an end view thereof.

The conveyor to which the invention is applied carries the lumber from the edger to the trimmer, and is generally known as the transfer. This conveyer is usually formed of a series of parallel chains composed of links of the roof top type. The conveyor is decked up so that the chains project above the deck or floor just sufficiently to take the lumber. In a conveyer of this kind, the lumber frequently stops on account of trash collecting on the floor, and to eliminate this objection, the present invention has been designed.

In the drawing, 5 denotes a series of roof top links connected to form' a chain, a series of which, as already stated, are placed side by side, to form the conveyer.

My link is interposed in the chain at suitable intervals. This link is also of the roof top type, it comprising a top 6, and sides 7, from one end of which project ears 8 between which extends a cross bar 9 fitting be tween the side walls of the adjacent links, a pin 10 passing through said parts forming the connection between the links. The top or roof of the link slopes downwardly in opposite directions from the center.

In the top of the link, intermediate its ends, is an openin 11 through which pro jects a roller 12. Between the side walls 7 of the link, extend transverse webs 13, which are suitably spaced apart, and between which the roller 12 is located. These webs carry an axle 1 1 on which the roller is journaled. The axle of the roller extends parallel to the longitudinal axis of the link, and the roller projects a sufficient distance above the top or roof of the link so that it may engage the lumber to be transferred or conveyed.

It will be noted that the roller is mounted transversely with respect to the link, which is for the purpose of facilitating the entry of the lumber onto the conveyor, the same dropping on the 'conveyer from one side thereof. The rollers act as lugs to take hold of the lumber and slide the same forwardly to the trimmer, after being deposited on the conveyor from the edger. As already described, the chains travel close to the floor or deck of the transfer, in view of which the lumber is frequently stopped if there is an accumulation of trash or rubbish on the floor. This stoppage of the lumber is entirely prevented by the rollers 12, as they come behind the lumber, and positively push the same forwardly past the obstruction.

\Vhat is claimed is:

1. A conveyer chain link having a closed top, and a roller carried by said link, and projecting from the top thereof, the axle of the roller extending parallel to the longitudinal axis of the link.

2. A conveyor chain link having a closed top, and an opening in said top, transverse webs below the top of the link, an axle carried by said webs, said axle extending parallel to the longitudinal axis of the link. and

3. A conveyer chain link having a closed PETER sianticlinal top, and a roller carried by the Witnesses:

link and projecting through the top. I J. W. DICKINSON,
