COLUMBUS C. BARKEB AND THOMAS CRANEY, OF BAY CITY, MICHIGAN.

FLOATING LOG-LOADER.

SPECIFICATION forming part of Letters Patent No. 313,293Vdated March 3, 1885,

Application filed December 10, 1884. (No model.)

To all whom it may concern: y

Be it known that We, COLUMBUS C. BAR- KER and THOMAS CRANEY, of Bay City, in the county of Bay and State of Michigan, have invented new and useful Improvements in Floating Log-Loaders, and we do hereby decla-re that the following is a full, clear and eX- act description thereof, reference being had to the accompanying drawing, which forms a part of this specification.

This invention relates to an improvement in floating log-loaders, especially designed for loading logs direct from the boom upon a floating carrier, such as a boat or doating crib.

The invention consists in the peculiar construction and arrangement of the parts, all as hereinafter set forth.

In the drawing which accompanies this speciication a perspective View of the device. is shown.

A is a lioat or raft,upon which the device is secured. B B are two inclined parallel skids placed transversely across the raft and extending with their lower ends into the water,while their upper ends reach beyond theopposite side of the raft. C C are chain-wheels secured upon transverse shafts D D. and E E are endless log-hauling chains passing over the chain- Wheels. These chains run in grooves upon the upper side of the skids, and have project-V ing spurs F.

In practice the device is floated alongside the carrier upon which the logs are to be loaded, and firmly secured thereto. The logs .are then iioated out of 4the boom toward the lower end of the skids and elevated up the incline,irom which they roll off onto the carrier.

To enable the device to elevate the logs to a Varying height, the lower ends of the skids are pivotally secured vto the raft, while their upper ends are supported upon vertically-adjustable standards G, any suitable device being used for raising or lowering them.

What we claim as our invention isl. In a floating log-loader, the combination of a float or raft with inclined skids supported by said iioat or raft and extending transversely across the same,with their lower ends extending below the bottom of said float and into the water and their upper ends projecting above and beyond the float, substantially as described.

' 2. In a lioating log-loader, the combination of a iioat or raft supporting inclined skids, which at one end extend into. the water and at the other end project beyond the lioat, of elevating devices, such as endlessvchains, and of suitable devices, such as the adjustable standards G, for changing the incline of the skids, substantially as described.
