Y TO ALL WHOM IT MAY CONCERN:`

v A n n Be it known that I, CHARLES C. COMSTOCK, of Grand Rapids, in the county of Kent, and-State of Michigan,

have invented a new, andkimproved Rafting-Dog; and .I do hereby declare that the following is a. full, clear,

und exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in whieh.

Figure 1 is a. perspective view of my inventiom, and

Figure 2 a transverse section of the same, in the line :c z, fig. l. Y

The object-ot this invention is to provide'a simple and cheap device for the purpose of attaching logs together to form`araft, and operating in such a inanner, that with it .the logs can be more expeditiously as well as .securely-fastened together than by the means now commonly employed.

In the drawings, A A are two wedg which may have a central brace, c, or not, as preferred by the raft'sman.

The logs are arranged side by side, as usual in the construction of rafts, and the ropes extend along the raft from end to end, stretching transversely across the logs, one rope at each end, and one or more intermediate'` between the Aend-ropes. In `this position the ropes are fastened firmly to the logs, by means of my improved device, in the following manner: The two wedges-are placed side by side and inserted into the link. A'.lheirpoints are then spread apart, and they, h eldtogetherby the link, are placed astride of the rdpc B, andin that positiondriven into the log, until the link presses so heavily upon the rope -as to hold it securely to the log, and prevent its slipping or becoming disengaged by any accident. i The relative position of the wedges, rope, and link, when operation upon a ratit, as above described, is clearly shown in iig. 1.

The whole device's simple and cheap, and by means of it the logs of n.4 raft can be connectedtogether with l the greatest ease, and mu'ch more rapidlythan by the old method of attachment.

Having thus described my invention, what I claim as new, and desire. to secure by Letters Patent, is- Y The combination ofthe two wedges A' A, the link C, and the rope'B, when employed together in the manner and lfor the purpose set forth. v The above specification of my inventionl signed by me, this 18th day of pril,A 1668.
