JOHN R. STINSON, OF IVI ALVERN, ARKANSAS.

LOGGING-BUNK.

T 0 all whom it may concern:

Be it known that 1, JOHN R. STINsON, a citizen of the United States, residing at Malvern, in the county of Hot Spring and State of Arkansas, have invented certain new and useful Improvements in Logging- Bunks, of which the following is a specificatio-n, reference being, had to the accompanying drawings.

This invention relates to logging bunks and has relation more particularly to a de vice of this general character wherein is included a retaining block; and an object of the invention is to provide a device .of this general character having novel and improved means whereby the retaining block may be effectively connected with the bunk proper in a convenient and effective manner.

The invention also has for its object to provide a device of this general character wherein the retaining block is capable of axial rotation independently of and relative to the bunk proper.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved logging bunk whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features ofthe invention will be carefully defined in the appended claims.

In order that my invention may be the better. understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is an elevational view of an extremity of a bunk constructed in accordance with an embodiment of my invention; Fig. 2 is a view similar to Fig. 1,-but taken at the opposite side thereof; and Fig. 3 is a sectional view taken substantially on theline 3-8 of Fig. 1.

As disclosed in the accompanying drawings, 1 denotes an extremity of a logging bunk which may be of any ordinary or preferred construction and the upper marginal portions of the sides of such block have suitably engaged therewith the plates 2 projecting above the upper face of the bunk 1 and affording a run-way adapted to receive the elongated plate 3 made preferably of metal and which is adapted to fit snugly within such run-Way, with its upper surface Specification of Letters Patent.

substantially flush with the upper longitudinal edges of the plates 2.

Pivotally engaged with the plate 3 adjacent one end thereof is the retaining block 4 of conventional formation whereby it will be seen that such block 4 will be permitted a certain degree of rotary movement relative to the bunk so that such block 4 may be enabled to turn, especially when it is being moved away from a log as will be clearly apparent to those skilled in the art to which my present invention appertains.

Directed through the block 4 at substan tially its center is the transverse bolt 5 of such a length as to project beyond the opposite faces of the block 4 and one extremity of such bolt 5 is bent to afford the hook member 6, the free extremity whereof is adapted to be received within a cavity 7 in the adjacent face of the block 4 whereby a loop is afforded, for a purpose which will hereinafter be explained.

Loosely engaged with the looped extremity or hook member 6 of the bolt 5 is the arm or strap 8 adapted to overlie a side of the bunk 1 and being provided in its opposite extremity with a suitable opening 9 adapted to register with the elongated longitudinally disposed slot 10 directed transversely through the bunk l and through which is adapted to be directed a locking key 10, one extremity of such key being provided with the lateral finger 11, while the opposite extremity is formed into a crank 12 whereby such locking key may be axially rotated in order to offset the lateral finger 11 relative to the opening 9, for reasons which will be hereinafter more fully explained. The opposite extremity of the bolt 5 is pivotally engaged by the extremity of a second arm or strap member 14 and is also adapted to be operatively engaged by the retaining nut or bur 15, whereby it will be readily perceived that such bolt 5 will be effectively maintained against operative displacement. The opposite or free end portion of the arm or strap 14 is also provided with an elongated longitudinally disposed slot 16 adapted to intersect the opening or slot 9 of the bunk 1 and through which the extremity of the locking key 10, provided with the finger 11, is adapted to be directed, it being obvious that such key must be properly adjusted in order to permit the passage of such extremity through the slot 16. After the finger 11 has been passed through the opening for a purpose which is believed to be selfevident.

From the foregoing description, it is thought to be obvious that a logging bunk constructed in accordance with my invention is of an extremely simple and comparatlvely inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled,

and it will also be obvious that my invention is susceptible of some change and modi- 'fication without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice.

I claim: 1. I11 combination with a bunk provided in a face with a run-way, a plate adapted to be received within said run-way, a block pivotally engaged with the plate, and means for maintaining the block in operative position.

2. In combination with a bunk, a block; supported thereby, a linkoperatively connected at one extremity with the block and provided at its opposite extremity with locking means and with a laterally directed hook member.

3. In combination with a bunk provided in its upper face with a run-way, a plate adapted to be received within such run-way, a block pivotally engaged with the plate,-

and means coacting with the block and bunk for maintaining the block in operative position.

l. In combination with a bunk provided with an elongated longitudinally disposed [opening therethrough, a block adapted torest upon the bunk, links pivotally engaged with the block and provided with openings adapted to register with the elongated opening of the bunk, the opening in one of the arms being elongated and disposed longitudinally of the arm, and a key adapted to be disposed through such registering openings, said key being provided at one extremity with a laterally disposed finger.

5. In combination with a bunk provided with an elongated longitudinally disposed opening therethrough, a block adapted to rest upon the bunk, links pivotally engaged with the block and provided with openings adapted to register with the elongated opening of the bunk, the opening in one of the arms being elongated'and disposed longitudinally of the arm, and a key adapted to be disposed through such registering openings,

said key being provided at one extremity v with a laterally disposed finger, the opposite" extremity of the key being provided with means wherebyv axial rotation may be imparted thereto. a

6. In combination with a bunk, a retained to overlie the block being provided with a hook member. 8. In combination with a bunk, a block supported thereby, a link operatively connected with the block said link being provided with a locking means and with engaging means. o

9. In combination with a bunk,ablock supported thereby, a link operatively connected at one extremity with the block and provided at its oppositeextremity with locking means and with a hook member.

In testimony whereof I hereunto aifix my signature in the presence of two witnesses.
