rThis invention relates to an adjustable brace designedv rimaril f for use in connece L" 1 tion with cable tools and rotary drilling rigs,

but it is to he understood that an adjustable brace in accordance With this invention may be employed for any purposes for ivliich it is found applicable, and the invention has for its object to provide, a strong, durable, compact, adjustable conveniently applied brace for bracing and for coupling and bracing a pair of elements together in a thoroughly efiicient manner.

`With the foregoing and other objects in view the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically de scribed, and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall Within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parte r throughout the several views:

Figure 1 is an elevation of an adjustable brace in accordance With this invention.

Figure 2 is a fragmentary view, in endelevation, upon an enlarged scale and lo`olring at right angles to the showingin F igure 1.

Figure 3 is a section on line 3-8 Figure 1 upon an enlarged scale.

Figure 4: is a sectionlon line Mil Figure 1v upon an enlarged scale.

Figure 5 is a section on line 5 5 .Figure Figure 6 is a perspective view of one of the abutment blocks.

An adjustable brace, in accordance With this invention, includes a pair of telescopic tubularinembers 1, 2 and each ofwhich has a closed outer end as at 3 andan angle shaped extension projecting from the outer end 3 and disposed at an angle with respect thereto@ The extension at the outer end of the section 1 is indicated generally at L1 and the extension at the outer end of the section 2 is indicated generally at 5. The extensions 1, 5 are oppositely disposed With respect to each other and each consistsv of a pair of arms 6, 7, the latter being of less length than the former and projects inwardly from the outer end thereof at an inclination. arm 6 is formed with apertures 8 for the passage et holdfast devices to edly secure lThe :in extension to the element With which it is associated when bracing and coupling together a pair of elements. j

The section 2 extends into the section 1 and in proximity to its inner end is provided 'with a pair of lengthwise extending, diametrically opposed slots9, 10 of appropriate length. The section 1 at its inner end is provided With a pair of lengthwise extending, diametrically opposed slots l1, 12 of appropriate length.

The sections 1 and 2 are adjusted relatively to each other and secured in adjusted position by a pair of oppositely disposed abutnient blocks 13, 1/1, a pair of oppositely disposed Wedges 15, 16 and a pair of clamping devices generally indicated at 17.

Each' abutment block comprises a rectangular body portion 19 formed With a pair of spaced transverse grooves 20,21'

and laterally flanged at one end as at 22. The blocks 13 and 14: are ada ated to extend through the slots 9, 10, 11 an 12 and are ogpositely disposed with respect to each other. l/Vhen the blocks are employed, the grooves of one block have positioned therein the outer end Walls of the slots 9, 10 and the other of said blocks is seated on the outer end Walls ,of the slots 11, 12. See Figure 3. When the blocks 13 and 14 are mounted in position, they are arrangedin. spaced relation, and the Wedges 15 and 16 extend between the blocks. As the blocks are oppositely disposed, when mounted in position, the flanges 22 of the'blocks ove-rlap the Vsection 1 at opposite sides thereof.

See Figure 3.V j Y Each Wedge comprises a triangular body portion 23 having the larger end thereof formedV integral with a'rectangular plate 24 of greater Width than the thickness of the body portion 23 and of greater lengthl than the Width of the latter and said plate .242; is disposed relative to the body portion 23 whereby it will extend from each side edge thereof, but one of the extending parts of said plate is of greater Width than the other and bifurcatedl as at 25. rlhe smaller end of the body portion 23 terminates in an inclined threaded projection 26 having the opposite sides thereof flattened as at 27 for passage through the bifurcated part of thev plate 24. Figure 3.

Each securing device comprises a nut 2S and a 'Washer 29. The Washers 2,9 are nterposed between the nuts 28 and the plates 24 or the wedges 15, 16 when the wedges are arranged in position. Figure 3. The wedges 15 and 16 are oppositely disposed relatively to each other and the inclined side of one wedge slides against the inclined side of the other wedge. The projection or extension 26 ot the wedge 15 extends through the plate 24 of the wedgel 16 and the extension or projection 26 of the wedge 16 extends through the biturcated portion oi' the plate 2st oft the wedge 15. 'lVhen the wedges 15 and 16 are arranged in position, the straight side ol the wedge 15 is positioned against the block 13 and the straight side of the wedge 16 is positioned against the block 14. Figure The wedges 15 and 16, in connection with the blocks 18, 14 provide means for shifting the sections 1 and 2 oit the body portion of the brace, relatively to each other, and after said sections have been shifted to the desired extent, the securing devices 17 are mounted in position and said sections 1 and 2 are tixedly retained in their adjusted position. Owing to the manner oi' setting up the blocks 13, 111 relative to the wedges 15, 16 and the providing of these latter with removable securing devices, the sections 1, 2 can be released from bracing position, with respect to a pair of elements, when desired.

It is thought vthe many advantages of an adjustable brace, in accordance with this invention, can be readily understood, and although the preferred embodiment of the invention is as illustrated and described, yet it is to be understood that changes in the details of construction can be had which will fall within the scope ot the invention as claimed.

What we claim is:

1. An adjustable brace comprising a body portion 'formed of a pair of telescopic sections, each of said sections 'formed with a pair of diametrically opposed slotsthe slots ot one section registering with the slots Vo the other section7 a pair of abutment blocks extending through said registering slots, a pair of oppositely disposed wedges interposed between said blocks, said wedges including threaded projections and bifurcated plates, said projections of one wedge extending through the bifurcated plate of the other wedge, and means mounted on said projections for maintaining said wedges in set position.

2. vAn adjustable brace comprising a body portion formed of a pair of telescopic sections, oppositely disposed abutment blocks extending through said sections diametrically thereof, oppositely disposed adjusting elements positioned between said blocks and arranged in abutting relation, one ot said elements having one end thereof extending through one end of the other of said elements, and means mounted on said ends for maintaining them in set position.

3. An adjustable brace comprising a body portion formed with a pair of telescopic sections., a pair of oppositely disposed abutment blocks extending through said sections diametrically thereof and arranged in spaced relation, one of said-blocks receiving one of saidk sections and the other of said blocks seated on the other ot said sections, and a pair of oppositely disposed, abutting adjusting elements having threaded projections at one end, the projection of one elekment beine' o a oositelf dis Josed with res Dect to the projection of the other of said elements, the projection of one element extending through oneend of the other element, and means mounted on the said projections `to; de't-achably securing said elements in adjusted position. i

A. An adjustable brace comprising a body portion formed with a pair oi telescopic sections, abutment blocks extending diametrically oic said sections and arranged in spaced relation, abutting, interengaging adjusting elements positioned betweenand abutting against said blocks, and means mounted on one of said elements and engaging the other of said elements for maintaining said elements in adjusted position.

ln testimony whereof, we aiix our signatures hereto.
