4 Claims. (o1. 198-200) The present invention relates to improvements in conveyer mechanism, and more in particular to novel structure in a chain conveyer such as used in hauling logs from a pond to the log deck of saw mills. l

Among the objects of the present invention is to provide a novel attachment for a chair or carriage to a link of a chain conveyer used for hauling or conveying logs in a saw mill, charac- Zerized as being of simplified construction with a minimum of parts and wherein the carriage r dogs may be conveniently assembled or disassembled in respect to the chain, thus saving a considerable amount of time where this becomes necessary because of worn parts needing replacement.

A further object of the present invention is to provide a novel connection between the dog or carriage and the conveyer chain such as used .121 saw mills, which is free of separate or loose parts and which is characterized by including a saddle on the carriage or chair adapted to embrhce a link and interlock with a saddle seat orovided thereon, the said assembly being so constructed and arranged as to permit the said carriage to be readily inserted in place over the carriage seat and being held in its assembled interlocking relation by means of a pin, bolt or any other similar means.

Other objects, features, capabilities and advantages are comprehended by the invention, as will later appear and as are inherently possessed thereby.

Referring to the drawing:

Figure 1 is a fragmentary view in elevation of a conveyer mechanism embodying the present invention;

Figure 2 is an enlarged view of a conveyer link and carriage embodying the novel structure of the present invention and disclosing the same somewhat more in detail than shown in Figure 1 of the drawing;

Figure 3 is a view in end elevation of the assembly shown in Figure 2 of the drawing;

Figure 4 is a top plan view of the assembly shown in Figure 2 of the drawing;

Figure 5 is a view in section taken in the plane represented by line 5--5 of Figure 2 of the drawing; and

Figure 6 is a view in cross-section taken in the plane represented by line 66 of Figure 2 of the drawing.

Referring now more in detail to the drawing, a conveyer mechanism selected to illustrate the present invention is shown in Figure l of the drawing as comprising a chain 2 formed of a plurality of interlocking links, one or more of which, such as the link 4, is of a particular construction and adapted to have secured thereto a carriage or chair 6.

The conveyer mechanism referred to is such as is used in conveying or hauling logs from the pond to the log deck of a saw mill, although it is to be understood that this invention may be embodied in other conveyers including link structure such as shown herein. The link 4 comprises a member formed with the opposed sides 8 and ID, with which is integrally connected a saddle seat or filler member l2 intermediate the ends of the said link. Said filler member is provided with the projections l4 and i6 extending laterally beyond the planes defining the side edges of the link which are adapted to be received in grooves l8 and 20, respectively, formed on the inner faces of depending legs 22 and 24 of the said carriage or chair 6. These depending legs 22 and 24 are connected to the base 26 of the carriage which has integrally formed therewith on its upper surface a plurality of marginal teeth or dogs, such as 28, and intermediate teeth or dogs such as 36, which form a seat or support for logs resting thereon whereby the same are conveyed by the conveyer chain 2 from one point to another in the milling operations. 7

It will thus be seen that the base 26, together with the spaced legs 22 and 24 of the carriage 6, provides a saddle embracing the link 4 and interlocking therewith through the medium of the grooves l8 and 20 which embrace the projections I4 and I6. In order to maintain this assembled relation between the carriage and link, the said filler member l2, as well as the depending legs 22 and 24, are provided with openings therethrough slightly staggered in respect to one another to receive a drift pin, such as 32, which may be driven into wedging relation with the elements of this assembly for holding the same in operative position. While the embodiment selected for the purpose of disclosing the present invention embodies a drift pin, nevertheless it will be readily appreciated that a bolt or any other element may be used for the same purpose.

As will be readily appreciated, the particular construction for the carriage 6 and the link 4 as hereinabove described for connecting the two together provides efiective means for interlocknew one with a considerable saving in time as compared to similar assembly jobs where a number of loose pieces are required to effect the connection. The novel interlock between the carriage and chain according to the present inven tion provides ample bearing surface for the carriage or dog to withstand the forces to which the same are subjected during the hauling of logs from one point to the other in milling operations. By the simple expedient of maintaining a reserve supply of links and chairs, such as 4 and 6, respectively, any repairs which become necessary can be readily and easily accomplished by removing any defective link or chair and substituting another.

While I have herein described and upon the drawing shown an illustrative embodiment of the invention, it is to be understood that the invention is not limited thereto but may comprehend other constructions, arrangements of parts, details and features without departing from the spirit of the invention.

I claim:

1. In a conveyer for logs or the like, the combination of a carriage having spaced depending legs formed with opposed grooves, a chain having a link provided with an integrally formed intermediate filler member projecting from said link and adapted to be received in said grooves, and means for securing said link and carriage in interlocked relation.

2. In a conveyer for logs or the like, the combination of a carriage having spaced depending legs formed with opposed grooves, a chain having a link provided with an integrally formed intermediate filler member projecting from said link and adapted to be received in said grooves, said legs and said filler member having openings therethrough, and a pin disposed in said openings and in wedging relation to said legs and filler member to hold said link and carriage in interlocked relation.

3. A link for a conveyer chain assembly having a carriage formed with spaced depending legs, said link comprising a loop member formed with oppositely disposed ends and sides, and a filler member intermediate of and spaced from said ends and being integrally connected to said sides and having shouldered portions projecting laterally of planes defining the said sides adapted to be received in cooperative relation with said spaced depending legs of said carriage.

4. In a conveyer for logs or the like, the combination of a carriage having spaced depending legs formed with opposed grooves, a chain having a link provided with a filler member extending between and rigidly connected to the sides of said link intermediate the ends thereof, said filler member having portions projecting from said link and adapted to be received in said grooves, said legs and said filler member having openings therethrough, and a pin disposed in said openings and in wedging relation to said legs and filler member to hold them in interlocked relation.
