ENDLESS CONVEYER CHAIN.
SPECIFICATION forming part of Letters Patent No. 690,934, dated January 14, 1902. Application filed August 3, 1901, Serial No. 70,775. (No model.)
To rtZZ whom it may concern:
Be it known that I, JOSEPH DICK, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented new and useful Improvements in Endless Oonveyer Belts or Chains, of which the following is a specification.
This invention relates to improvements in endless conveyer belts or chains.
The object of the invention is to provide an endless conveyor in which the links comprising the bars and sprocket-engaging members are formed in one part, thus obviating the use of wood slats, and are detachable, so that any link may be removed from the chain without disturbing the other links or detaching, any fastenings and so that the links may be readily and conveniently assembled and disassembled.
With this and other objects in View, which will appear as the nature of the improvements is better understood, the invention consists of certain novel features of construction, combination, and arrangements of parts, as will be hereinafter more fully described, and particularly pointed out in the appended claims.
In the accompanying drawings, Figure 1 is a top plan perspective View of a portion of a link belt or conveyor embodying my invention. Fig. 2 is a bottom perspective View of two links of the chain, showing them arranged as when about to be coupled together. Fig. 3 is a bottom plan view of two of the links coupled, and Fig. at is a sectional view on the line a e of Fig. 2.
Referrring now more particularly to the drawings, the numeral 1 designates a portion of an endless chain or conveyor, the same being composed of a series of jointed detachable links 2. Each of these links consists of a bar or body portion 3, formed at each end with an integral sprocket member or socket 4 for engagement with the teeth of the supporting sprocket-wheels, the bar and sockets being preferably formed in one part of a single casting, so as to obviate the use of wood slats and provide a link of great simplicity and maximum strength.
The links are jointed and detachably con nected in the following manner: The socket a at each end of the bar is formed upon one side with a hook 5 and upon the other side with a slot 6 and a pintle '7, the said hooks and pintles being adapted to interlock with corresponding pintles and hooks on the next adjacentlinks, while the slots 6 allow the hooks to move to the required extent to adapt the links to have free articulation. Each pintle '7 is too large to be passed through. the contracted throat of the hook into the receiving space or opening of the hook and can only be inserted therein and withdrawn therefrom by an endwise movement. To this end each bar is provided at one side adjacent to the inner end of one of its sockets at with a longitudinal groove or channel 8, leading into said socket in line with its slot 6, and is provided along its contiguous side edge with a reduced portion 9, which is sufficiently narrow to enter the throat of a connecting-hook 5 and allow the bill of the hook to enter the groove 8. By this construction it will be seen thatwhen two links are placed in the relative positions shown in Fig. 2, with the end of one link projecting beyond the other, the pintle 7 upon one end of one of the links will lie in longitudinal alinement with the coacting receiving'space of the hook 5 upon the contiguous end of the other link and that the hook and cooperating reduced portion 9 at the opposite ends of said links will be arranged coincidently, so that by first moving the latternamed ends of the links toward each other the hook will enter the groove 8, and a longitudinal sliding motion of the links in a direction to bring their ends in alinement will bring the hooks 5 into engagement with the pintles 7, thus jointing the links together. A reverse movement of the links will, it will be readily understood, elfect their ready separation. Hence it will be seen that the links of the chain or conveyer are adapted to freely articulate and to be quickly assembled and disassembled and that one link may be detached without disturbing any of the others or releasing any auxiliary fastening devices.
From the foregoing description, taken in connection with the accompanying drawings, the construction and mode of operation of the invention will be readily understood without a further extended description, and the advantages thereof will be obvious.
Changes in the form, proportion, and minor details of construction may be made within the scope of the invention without departing from the spirit or sacrificing any of the ad: vantages thereof.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. An endless conveyer consisting of jointed detachable links formed with sprocket members having connecting hooks and pintles, each link having a reduced edge portion and a channel leading therefrom to one of its sprocket members to admit the cooperating hook on another link, whereby two links may be connected and disconnected by a longitudinal sliding movement, substantially as described.
2. An endless conveyer consisting of jointed detachable links, each consisting of a bar having integral sockets or sprocket members provided with hooks and pintles, all formed in a single casting, each link having a reduced edge portion and a channel leading therefrom to one of its sprocket members to admit the cooperating hook on another link, whereby two links may be connected and disconnected by a longitudinal sliding movement, substantially as described.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
