COMBINED SLED-STAKE AND LOGGING-BUNK.

Application filed December 9, 1912.

To all whom it may concern:

Be it known that I, WILLIAM A. HUM- PHREY, a citizen of the United States, resid ing at Sparta, in the county of Monroe and State of Wisconsin, have invented a new and useful Combined Sled-Stake and Logging- Bunk, of which the following is a specification.

This invention relates to a combined sled stake and logging bunk, one of its objects being to provide a structure of this character which can be quickly constructed for use either upon ordinary sleighs with or without boxes, or to be used as a bunk of extra length for hauling logs, railroad ties, etc., thus obviating the necessity of using the ordinary cumbersome wooden bunks.

Another object is to provide a combined stake and stake holder which can be extended perpendicularly from the bunk or runner and which can also be supported in a substantially horizontal position beyond the end of the bunk or runner.

A further object is to provide cooperating means upon the said combined stake and stake holder and upon the bunk or runner whereby the parts are properly held in the positions to which they are adjusted.

With the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invent-ion has been shown.

In said drawings: Figure 1 is a side elevation of the structure constituting the present invention, the two combined stakes and stake holders being shown, by full lines, in different positions and, by dotted lines, in a third position. Fig. 2 is a perspective view of one of the combined stakes and holders. Fig. 3 is a detail view of one of the braces. Fig. 1 is a perspective view of a stirrup. Fig. 5 is a perspective view of a portion of the protecting strap and showing the stop at one end thereof.

Referring to the figures by characters of reference 1 designates either a bunk or a runner, according to the use to which the Specification of Letters Patent.

present improvements are to be put and, for convenience in describing the invention, this part will be designated the body. Said body is provided, along its upper face, with a wear or protecting strip 2 of any suitable metal and the ends of which are curved downwardly on to the curved ends of the body 1, as shown at 3, the terminals of these downwardly curved portions 3 being outturned to form stops 4.

A pivot bolt 5 extends transversely through each end portion of the body 1 and also through the terminals of an elongated metal loop 6 which straddles the body and has its upper portion contracted, as at 7. A socket S is formed by enlarging the loop at that end thereof remote from the bolt 5 and this enlargement is of such size as to receive the rounded end 9 of a wooden stake 10, when it is desired to elongate the bunk or to use a wooden stake in connection with a runner. This arrangement of the stake relative to the loop 8 has been indicated at the right of Fig. 1. Extending transversely through the contracted portion of the elongated loop or stake 6 is a pivot bolt 11 to which is connected the upper end portion of a brace 12. This brace is given a one quarter turn, as shown at 13 so as to provide a broad slightly curved tongue 14. A guide bolt 15 extends transversely through the body 1 between each bolt 5 and the adjacent end of the body and the ends of this bolt extend into slots 1 6 formed longitudinally within the sides of a substantially U-shaped stirrup 17 which straddles the end portion of the body 1. Notches 18 are formed in the upper edges of the sides of stirrup 17 and are adapted, when the stirrup is in one position, to receive the ends of a holding pin 19 which extends transversely through the body. When the notches are thus positioned, the bolt 15 is located in the slots 16 at points adjacent the centers thereof, as shown at the right of Fig. 1.

When it is desired to use the metallic stakes 6, they are swung upwardly so that each of them will be positioned, as shown at the right of Fig. 1 and with its brace bearing downwardly upon that portion of the strip 2 on the end portion of the body 1. Stirrup 17 is then swung upwardly to an inclined position and pushed inwardly and downwardly until the notches 18 come under the pin 19, this pin thus holding the stirrup against downward movement when subjected to the pressure exerted thereagainst by the brace 12.

Should it be desired to use a wooden stake, the metallic stake is swung clownwardly to the position illustrated at the left of Fig. 1. In order to effect this movement the stirrup 17 is first disconnected from pin 19 so as to swing downwardly under the end portion of the body 1. The brace 12 is thus free to slide through the stirrup and againstthe stop 4 and, as the brace bears clownwardly on the middle portion of the stirrup, it will be seen that the metallic stake 6 will thus be supported in a substantially horizontal position. With the parts thus disposed, a wooden stake 10 can be placed in position as shown.

WVhen it is not desired to use either stake, the brace 12 can be slipped under the stirrup 17 so as thus to allow the metallic stake to swing downwardly past the stirrup and to the position indicated by dotted lines in Fi 1.

it is to be understood that under some conditions it is desirable to use a wooden stake at both ends of the body 1 while, under other conditions, it is desirable to use only the metallic stake at both ends. At other times, as when the body is arranged on a hillside and is thus likely to tilt over under the weight of the load thereon, the stake 6 at the uphill end of the body can be lowered to the position indicated at the left of Fig. 1 and a wooden stake placed therein while the metallic stake at the lower end of the body can be arranged as shown at the right of Fig. 1. Thus the load can be so placed as to bring the center of gravity to the upper side of the center of the supporting structure and the danger of tilting or upsetting is therefore reduced to the minimum.

What is claimed is z- 1. The combination with a body, of a combined stake and stake holding element pivotally connected thereto, a brace pivoted upon said element, and means slidably and pivotally mounted upon the body and cooperating with the brace for holding said element in either horizontal or vertical load retaining position.

2. The combination with a body, of a combined stake and stake holding element pivotally connected thereto, a brace pivoted upon said element, a stop upon the body, and a brace engaging device slidably and pivotally connected to the body for holding said element in either horizontal or vertical load-retaining position.

3. The combination with a body, of a combined stake and stake holding element pivotally connected thereto, a brace extending from said element, a stop upon the body, a brace engaging device pivotally and slidably connected to the body, and a holding device upon the body for engagement by said engaging device to hold said element in either horizontal or vertical load-retaining position.

4C. The combination with a body, of a combined stake and stake holding element pivotally connected thereto, a stop upon the body, a stirrup slidably and pivotally mounted upon one end portion of the body, and a brace pivotally connected to said element and slidable through the stirrup and against the stop, said stop, brace and stirrup constituting means for holding said element in a substantially horizontal position.

5. The combination with a body, of a combined stake and stake holding element straddling and pivotally connected to the body, a stirrup pivotally and slidably mounted on the body, a stop upon the body for engaging and holding the stirrup in a predetermined position, and a brace pivotally connected to said element and movable against the stirrup for holding said element in an upstanding position.

In testimony that I claim the foregoing as my own, I have hereto afixed my signature in the presence of two witnesses.

WILLIAM A. HUMPHREY.
