MUD GuAnnron SUBMARINE nRILLsQ Application filed June 25, 1926, vSerial No. 118,489. Renewed lune 23, 1927."
This inventionrelates to submarine drills, but more particularly'to' an adjustable mud guard or protective shield for the hollow drill steel of a submarine hammer drill unit.
The type of hammer drill unit to, which the invention relates is like thatdisclosedinmy Patent No. 1,610,372 datedDecember 4;, 1926, for Submarine hammerdrill unit. In that case the-mud guard is secured to a supplel0 mental frame guided on the main frame which carries the drilling elementorx drillingframe provided With the hammer .drill. The whole weight of the drilling element is located upon the mud guard to force it through the loose material down to the rock to be drilled. This modeof operation is also carried out in accordance with the present construction, but in the present instance, the mud guard is slidably supported at the lower end of. a spud or guide frame which is movable vertically in the main frame. The drilling element or drilling frame carrying the hammer drill is sli dably supported and guided in the spud or guide frame, so that a any one of these three movable elements may be adjustable relatively to the other two and all three elements are adjustable relatively to each other. j
' The object of thus making the elements relatively adjustable is to aiford greater facility in protecting the drill steel and in carrying out thedrilling operations. I Another object of the invention isto provide means inconnect-ion with the mud guard to 'center the drill steel as well as guide and support the mud guard close to the rock to be drilled.
The invention is shown in one of its pre- 40 in which i j i I Figure 1 is a diagrammatic side elevation partlybroken away showing a portion ofa barge and one drilling unit, 1
Figure 2 is an enlarged detail vertical secferred forms in the accompanyingdrawings,
' tional view of the mud guard, and
Figures 3, 4 and 5 are enlarged detail transverse sectional views taken respectively on the line 3-3of Figure 1, and the lines 44 and 55 of Figure 2 looking downwardly in the direction. of the arrows; I, I
Referring to the drawings, the barge A, only a portion of which isshown, may be of "any suitableor usual construction for sub- 7 marine drilling and is adapted to have 55. mounted thereon one or more submarine drilling units B, only one unit being shown i in Figure 1, and eaci unitisprovidedlwith a submarine rock drill C of the hammertype adapted to be submerged in the water 7 D 'duringthe operation o drilling. ,The, loose material and broken rock usually lying in tools required for submarine drilling, alo though, for purposes'of simplicity, these particular machines and engines are not shown, it being understood that the rockdrillC or drills, forming a part ofthedrilling unit, are preferably adapted Ito-be operated by motive fluid, as for instance compressed air, in which case a compressor 01' compressors would be required.
Eachsubmarine drilling unit of the ham m'er type as shown, is provided with alinain frame H of' any suitable construction preferably in the form of a tower of moderate height, andhavingi guides 'J which may be in the form of angle irons secured tothe plates L and: extending downwardly 'asufli cient distance to thevpoints a for instance, to guide andsupport a s ender guideframe K which is vertically movableonthe guidesJ and is of sufiicient length to extend downwardly in the water to the bottom or to a point inthe loose material, on the bottomadjacent the rock to bedrilled.
The guide frame K may beof anysuitable construction, but in thisinstance, comprises the channel irons O secured to the plates P as by means of, thebraces Q at one side, the
opposite side of "the platesPibeing provided with theguide lugs or jaws R so that the guides J extend between the guide frame plates P and the guide jaws R. a
The guide frame K is itself provided with the guides WT I and the movable drilling element or drilling frame Vlwhich'rarries the hammer drill C is provided with the guide plates in the form} of angle irons Wsothat the drilling I elementjis guided as it .is' moved .vertically on the spud or guide frame K. The hammer drillC having a cylinder S, and
the bell to T may be suitably secured Ito, the
drillingframe V and any suitable meansas, H0
through the tubular mud guard 's slidably supported and guided in the shoe a secured atthe lower end of the guide frame K. The mud guard s is provided with a flared upper end t having the guide flanges a2 guided'on @1 9 guides V of th'e guide frame K. A rope or cable p is secured to the flange w at the upper end of the mud guard for adjusting the mudguard in the shoe or guide member a. The lower end of the mud guard ,s preferably provided with a renewable In the operation of the apparatus, the spud or guide frame K is first lowered into the waterand then the mud guard is adjusted as desired in or upon'the loose material at the bottom. The drilling element or drill ing frame carrying the rock drill is then lowered upon the mud guard and the drill steel passes through the tubular mud guard ready for the commencement of the drilling operation. The weight of the drilling element together with the vibration due to the operation of the hammer drill forces the mud guard down through the loose material at the same time that the drill steel is penetrating said material, until the mud guard is seated firmly upon the solid rock. The drilling element may then be raised and a longer steel inserted and since the mud guard is guided securely in the guide frame K and centered therein, no'trouble will be experienced in inserting a new drill steel in the mud guard. Furthermore, the mud guard will not be displaced or deranged due totide waters or to currents in th'e'water at thepoint of drilling I I claim: 7
