DERRICK CONNECTION.

Specification of Letters Patent.

Patented May 21, 1912.

Application filed July 31, 1911. Serial NO. 641,569.

To all whom it may concern:

Be it known that I, WILLIAM Brsrror, a citizen of the United States of America, reat Saxonburg, in the county of Butler and State of Pennsylvania, have invented certain new and useful Improvements in Derrick Connections, of which the followingis a specification, reference being had therein to the accompanying drawing.

This invention relates to derrick connections, and the primary object of the invention is to provide a metallic connection whereby the braces and girts can be easily, quickly and detachably connected to the uprights of a derrick.

Another object of the invention is to provide a derrick connectionthat will maintain a rigid and durable connection between the uprights when the derrick is in use and allow'the parts of the derrick to be quickly disassembled moved.

These and such other objects as 1nay hereinafter appear are attained by the novel construction, combination and arrangement of parts to be hereinafter specifically described and then claimed.

Reference will now be had to the drawing, wherein 2- Figure of a derrick in accordance with this lnvention, Fig. 2 is an enlarged side elevation of the derrick connection, with the gate-block removed, Fig. 3 is an elevation of a detached gate-block, Fig. 4 is an elevation of the der rick connection, showing the gate-block in position and closed, Fig. 5' is a horizontal sectional view of a derrick connection with one of the gate-blocks removed, Fig. 6 is a plan of a detached locking bolt forming part of the derrick connection. Fig. 7 is an enlarged perspective view 'of one of the anchoring bolts for the braces and girts. Fig. 8 is a view illustrating one of the c'onnecting sleeves, and Fig. 9 is a view illustrating the pivotal connection between the gate block and the bearing block.

In the drawing the reference numeral 1 denotes-metallic cylindrical uprights of a rigging, and these uprights are adapted to be connected by tubular girts 2 and angutubular braces 3. The device I employ for connecting the ends of the girts and braces to the uprights 1 consists of a sleeve 4 mounted upon the uprights 1 and whenithe same is to be.re-

1 is a side elevation of a portion having the upper and lower ends thereof split and provided with outwardly projecting lugs 5 adapted to be connected by screws or bolts 6, whereby the upper and lower ends of the sleeve 4 can be clamped upon the upright 1. The sleeve 4 is provided with radially disposed ribs 7 and 8, the rib 7 being at right angles to the rib 8 and both of said ribs of less length than the sleeve 4. Each rib is apertured and connected to each rib by bolts 9 and nuts 10 is the bifurcated or longitudinally slotted edge 11 of a bearing block 12, said block being rectangular in elevation and of a thickness corresponding to the diameter. of the sleeve 4. The bearing'block 12 has the inner face thereof provided with T-shaped grooves 13 and 14, the grooves 13 being disposed at an angle to the groove 14 and accommodating the T-shaped heads 15 of anchoring bolts 16 and 17, the bolts 16 being screwed in the ends of the braces 3 and the bolt 17 in the end of a girt 2.

The anchoring bolts 16 and 17. are re tained in engagement with the bearing block 12 by a gate-block 18, said block having one edge thereof provided with barrels 19 extending into openings 20 provided therefor in the bearing block 12, said barrels being pivotally connected. to the latter by a pin 21 passing downwardly there through and through vertically alining openings 22 provided therefor in the bearing block 12. The gate-block 18 is retained in a closed position by locking bolts 23 and 24, the bolts 23 having single apertured heads 25 and the bolt 24 having a double apertured head 26. These bolts are retained within openings 27' provided therefor in the bearing block 12 by nuts 28 and the heads 25 and 26 of said bolts are adapted to extend throiwh slots 29 provided therefor in the gate-block 18. \Vhen the gate-block 18 is closed, a wedgeshaped pin 30 extends through thehead 25 of the upper bolt 23 into the head 26 of the bolt 24, and another pin 31 extends through the head 26 of the bolt 24 into the head 25 of the lower bolt 23, said pins being loosely connected to the outer side of the gate-block 18 by chains 32 attached to the gate-block, as at 33.

' With thegate-block 18 open and the anchoring bolts 16 and 17 connected to the braces and girts, it is obvious that the anchoring bolts can be quickly plated in engagement with the bearing block 12, the gate-block closed and the anchoring bolts firmly held.

The connection in its entirety is made of strong and durable metal, and it is to be understood that the structural elements thereof can be varied or changed without departing from the scope of the invention.

IV hat I claim is.: g

1. In a derrick connection, the combination with uprights, braces and girts, of anchoring bolts carried by the ends of said braces and girts, a bearing block supported by said uprights and adapted to receive the ends of said anchoring bolts, and gate-blocks pivotally connected to said bearing blocks and adapted to be closed to retain said an choring bolts in engagement with said bearing blocks.

2. In a derrick connection, the combination with uprights, braces and girts, of anchoring bolts carried by the ends of said braces and girts, a. bearing block supported by said uprights and adapted to receive the ends of said anchoring bolts, gate-blocks pivotally connected to said bearing blocks and adapted to be closed to retain said anchoring bolts in engagement with said bearing blocks, and means for retaining said gate-blocks in a closed position.

3. In a derrick connection, the combination with uprights, braces and girts, of anchoring bolts carried by the ends of said braces and girts, sleeves mounted upon said uprights, bearing blocks carried by said sleeves and adapted to receive the ends of said anchoring bolts, gate-blocks pivotally connected to said bearing blocks and adapted to be closed to retain said anchoring bolts in engagement with said bearing blocks, and means adapted to retain said gate-blocks in a closed position. 7

4. In a derrick connection the combination with uprights, braces and girts, of anchoring bolts carried by the ends of said braces and girts, sleeves mounted upon said uprights, bearing blocks carried by said sleeves and adapted to receive the ends of said anchoring bolts, gate-blocks pivotally connected to said bearing blocks and adapted to be closed to retain said anchoring bolts in engagement with said bearing blocks, means adapted to retain said gateblocks in a closed position, said means including locking bolts carried by said bearing blocks and pins adapted to extend through said bolts.

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

' WILLIAM BISHOP.
