FERDINAND JULES CORVILAIN, OF BILBAO, SPAIN.
DIAMOND-SET TOOL.
Application filed August 17, 1911.
To all whom it may concern:
Be it known that I, FERDINAND Jones CoRviLAIN, a subject of the King of the Belgians, andresiding at Bilbao, Spain, have invented a certain new and useful Improvement in Diamond-Set Tools, of which the following is a specification.
This invention relates to diamond-set tools such for instance as boring crowns set with diamonds for cutting through rock or like material.
The invention contemplates the use of diamonds previously artificially shaped to substantially conical form by grinding two diamonds together on a grinding machine to correspond with the sockets in which they are fitted.
The invention as embodied in a diamond boring crown is illustrated in the accompanying drawings in which Figure 1 is a part elevation part vertical section; Fig. 2 is a plan; Figs. 3 and 4 are like views to Figs. 1 and 2 but show the diamonds differently inclined. Figs. 5, 6, l and 8 show modifications.
Referring to Figs. 1 to 4 of the drawings, the diamond crown comprises a tubular crown piece A having a screw-threaded stem B whereby it is fixed to the actuating member, 6., the boring tube. In the boring face of the crown piece A sockets C of conical formation are cut for the receptiog of the diamonds D which are previously artificially shaped to fit the sockets, these sockets being wider at one end than at the other so that the apices of the diamonds, when the latter are fitted in place with the usual cement, protrude beyond the sockets, as shown particularly in Figs. 1 and 3. The diamonds are preferably entered into sockets which are disposed at an inclination to the axis of the crown piece, said diamonds being entered preferably through inclined orifices E in axial alinement with said sockets. The crown piece is also formed wit-h preferably inclined orifices F into which are fitted steel or like pins G which are provided with inclined faces H adapted to press on the inner ends or bases of the diamonds and maintain said diamonds in position, the free ends of said pins G being acted on for this purpose as by means of a collar I freely mounted on said stem B and adapted to be engaged by a nut or sleeve J in screwthreaded engagement with said stem and adapted to be locked by a nut K or the like.
Specification of Letters Patent Patented June 25, 1912. Serial No. 644,644.
Referring to Figs. to 8 of the drawings, the boring face of the tubular crown piece A has sockets C of conical formation for the reception of the diamonds D which are previously artificially shaped to fit said sockets and are held securely therein by means of packing L consisting of suitable cement applied to their rear faces. The stem of the crown piece A is slotted to provide a plurality of depending portions M, which portions are screw-threaded externally so as to be engaged by the internally screw-threaded sleeve J, which sleeve is formed with an annular shoulder N adapted to engage with a corresponding shoulder P on a sleeve Q as shown particularly in Figs. 5 and 6, which sleeve Q is adapted to be secured to the boring tube and is formed with extensions R which enter the slots formed between the depending portions M of the crown piece. The extensions R are provided with inclined faces S which are caused to exercise pressure on the packing F on correspondingly shaped faces on the crown piece A by means of the screw-threaded sleeve J. The constructions shown in Figs. 5 to 8 are substantially the same except that the diamonds are shown differently inclined.
In the constructions described the diamonds are held without calking and they are not liable to drop out even on wearing of the base of the crown, while they may be removed and replaced with case; also tempered steel can be used in forming the crown in lieu of the mild steel employed when calking has to be resorted to.
In the constructions shown in Figs. 1 and 3 the adjustable pins G have a wedging action against the rear ends of the diamonds to hold them tightly in their sockets, and these pins are adjustably forced toward the diamonds by means of the nut or collar J having a screw-threaded engagement with the stem B of the hollow boring tool. In the construction shown in Figs. 5, 6, 7 and 8 the inclined faces S at the ends of the ex tensions R of the sleeve Q, press with a wedging action against the packing L be hind the inner ends of the diamonds, the crown piece A on which the diamonds are mounted being forced toward the said extensions R of the sleeve Q, by means of the screw-threaded sleeve or nut J which engages the screw-threaded depending portions M on said crown piece. In these dif ferent constructions, therefore, the adjustable parts for holding the diamonds in place by wedgingaction are movable longitudinally ofthe tool, as will be understood. By virtue of the adjusting means just referred to any looseness, occasioned by wear, which the diamonds may have in their sockets, may be readily taken up, so that the diamonds may be held tightly and rigidly in place, at all times.
Having now described my invention what I claim and desire to secure by Letters Patent of the United States is 1. A hollow boring tool provided with an annular tubular crown piece having an eX- ternally screw-threaded stem and having'a plurality of conical or outwardly tapering sockets, a plurality of diamonds artificially shaped to conical or outwardly tapering form to fit said sockets, an internally screwthreaded element adapted to engage the screw-threaded stem of the crown piece, and means adapted to have a wedging adjusting and holding action on the several diamonds and arranged to be forced toward the rear faces of the diamonds to maintain them tightly in their sockets on the rotation of the said internally screw-threaded element.
2. A hollow boring tool provided with an annular crown having longitudinal orifices and a plurality of conical or outwardly tapering sockets disposed at an inclination to the axis of the crown, diamonds artificially shaped to conical or outwardly tapering form to fit said sockets, a plurality of adjustable holding pins located in said orifices and having inclined outer end faces bearing with a wedging action on the rear faces 01 the diamonds to hold them tightly in their sockets, and a common adjusting and hold ing means acting against the inner ends of the several-holding pins, to maintain them firmly in holding positions. a
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
