JOHN H. .ANDERQON, OF ST. PAUL, MENNESOTA.

BOLSTER STAKE.

Application filed December 24, 1928. serial No. 432,955.

T all whom it may concern:

Be it known that 1, JOHN H. ANonnsoN, a citizen of the United States, resident of St. Paul, county of Ramsey, State of Minnesota, have invented certain new and useful Improvements in Bolster Stakes, of which the following is a specification.

The object of my invention is to provide improved means for mounting a stake on a wagon or sled bolster or beam which will dispense with the necessity of mortici the bolster or providing a socket therein or forming a tenant on the end of the stalre to fit the mortice or socket and thereby considerable expense may be saved in the cost of the bolster and stake.

A further object is to provide improved means for securing the stake to the bolster which will hold it firmly under all conditions and will not in any way interfere with the placing of the load on the wagon or sled or removing it therefrom.

A further object is to provide a reinforcing means for the stake which will form a rigid brace therefor and exerting a longitudinal pull on the stake, hold it securely to its seat on the bolster.

Other objects of the invention will pear from the following detailed description.

In the accompanying drawi forming part of this specification,

Figure 1 is an elevation of a portion of a wagon and bolster thereon, showing the manner of mounting the stake,

Figure 2 is a detail sectional view on the line 22 of Figure 3,

Figure 3 is an end view of the bolster and the stake mounted therein,

Figure 4 is a sectional view on the line l-l of Figure 3.

In the drawing, 2 represents a wagon axle, 3 the wheels therefor and la bolster ordinary construction, mountedin any suitable or preferred way on the axle. 5 is an. upright stake having a lower end seated on the bolster or beam and provided preferably with a longitudinal groove 7 that is adapted to receive an elongated U-shaped bolt 8 which extends from end to end of the stake and fits within sockets 6 and has lock nuts 9 thereon seated against a plate 10 on the underside of the bolster. The bolt 8 is preferably made of round iron of suitable gauge, and fits within the groove or recess in the stake so that the outer portion of the bolt is flush substantially with the side walls of the stake without, however, projecting outwardly beyond these walls and forming an obstruction to con tact with any material that may be loaded on the bolster or removed therefrom. In other words, the exterior surface of the stake presents a smooth, unobstructed appearance and any material on the bolster may be readily removed without danger of contacting with the reinforcing irons of the hoist r stakes. When the bolt is tightened, the stake will be clamped securely in place on the bolster.

The end of the bolster preferably has a curved strap 11 fitting thereon, fastened at the ends by rivets 12 and a bolt 13 passes through the bolster, thereby bracing and strengthening the end thereof. I prefer also to provide loops or stake-rings let at inte vals on the stake secured thereto by pivot pins 15 and adapted to swing outwardly to a horizontal position for connection with a chain or cable for holding the load on the bolster, or when not in use these loops may be swung down against the wall of the stake. Each end of the bolster is equipped with a stake of similar construction.

With the foregoing construction, no mortice is necessary in the end of the bolster, tending to weaken it, and no tenant is formed on the end of the stake or the stake shaped to lit the mortice or socket in the bolster. The squared end of the stake is seated firmly on the bolster and clamped thereon by the U-shaged bolt and rigidly held under all conditions of use. llhew ever desired, however, the bolt nuts may be loosened and the bolt raised, allowing the s eke to be disengaged therefrom.

I claim as my invention:

The combination with a bolster. of a stake having a flat lower end seated loosely on the top of the bolster and having a groove extending up through one vertical. face and down through its opposite vertica face, a, U-shaped bolt fitting within said ,QJTDOTQ and bearing on the upper end of said staue the ends of said bolt passing through said boh ster and having threads and nuts for drawing said boltdownward and clamping said stake entirely through the engagement of said bolt with the bottom and walls of said.

groove.

In witness whereof, I have hereunto set my hand this th day of December, 1920.,

' JOHN H. ANDERSON.
