MAST.
Application filed November 27, 1922. Serial No. 603,590.
This invention relates to an improved mast for drilling machines and the like, the general object of the invention being to provide a telescopic mast with improved means for supporting the parts in extended position.
Another object of the invention is to provide means for rotatably supporting the mast upon its base.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim. 7
In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is an elevation of the improved mast.
Figure 2 is a longitudinal sectional view.
Figure 3 is a view taken at right angles to Figure 1.
Figures at and 5 are detail views.
In these views 1 indicates the lower part of the mast and 2 the upper part thereof which telescopes into the lower part. The upper 361i? carries the frame 3 for the pu lleys 4, this frame being first bolted to the part 2 and then electric welded thereto. A semi-circular member 5 is held in engagement with the top of the lower section by means of the U-bolt 3 and the semi-circular part 7 which is welded to the bolt. The member 5 carries a forked arm 8, in the fork of which is pivoted a pulley 9. A casting 10 has its cylindrical part 11 placed in the lower end of the part 2, the flange 12 engaging the lower end of said part This casting is provided with a hole 13 through which acable it passes and a clamp 18 is fastened to the same. This cable passes up through the lower section and through a hole in the member 5 incl then passes over the pulley 9. This cable is connected with any suitable means for pulling upon the same to lift the upper section and the lower section. When the pper section is raised it is held in raised position by passing a pin 15 through one of the holes 16 in the lower section and between the ears 17 on the casting 10. Thus the upper section will rest up on the pin and thus be held in its raised position. A screw shaft 17 passes through a screw threaded hole in the bottom of the lower section and tnis shaft has a rounded head 18 on its lower end for engaging a semi-spherical socket formed in a base 19. This screw makes it easy to line the top of the mast with the well.
It will be seen from the foregoing description that l have provided a mast that is very simple and very durable and one which may he easil lined up with the well.
it is throught from the foregoing description that the advantages and novel features of my invention will be readily apparent.
I desire it to be understood that I may maize changes in the construction and in the co ahination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.
What I claim is:
A mast comprising a pair of telescopic sections, a cap, a flange member fitting in the lower end of the top section, with the section resting upon the flange, depending ears on said member, the lower section having holes therein, a bar adapted to he passed through. any desired pair of such holes and between the ears for supporting the upper section in adjusted position, a cable connect ed with the flange of said member and passing upwardly through the lower section, a two part collar surrounding the upper end of the lower section, an ear on one part of the collar, a pulley carried thereby over which the cable passes and means for de tachably connecting together the two parts of the collar.
In testimony whereof HARRY A. CLARK.
I aflix my signature.
