SPECIFICATION forming part of Letters Patent No. 783,006, datedFebruary 21, 1905.
Application filed Kay 11, 1904. Serial No. 207.465.
Be it known that we. Lomnon W'ILLIAMsand (.iUS'IAFJOHNSON,(itiZCDSOf the United States, residing at Doerun, in the county of St. Fran- .cois and State of Missouri, have invented a new and useful Coupling, of which the following is a specification.
This invention relates more particularly to that class of couplings employed in connecting diamond drills to feed-screws; but those skilled in the art will readily perceive that it inay be employed for other analogous purposes.
vide a structure which is very simple and com- 'and rigid coupling or chuck which will not readily break or open to release the drill secured thereby.
Another object is to provide simple devices which will hold the drillagainst movementin the chuck, said devices being detachable. so
. that if worn or injured they may be readily 1 removed and replaced by newones, being, fur- 40 sponding parts in all the figures of the drawmgs.
thermore, very simple, and consequently inexpensive, in construction. The preferred embodiment of the invention is illustrated in the accompanying drawings;
" but it will beapparent that the structureillustrated may be changed and moditied without departing from the spirit of the invention.
In said drawings, Figure 1 is a perspective 1 view of the coupling.
Fig. 2 is a longitudinal sectional view through the same. Fig. 3 is a transverse sectional view taken on the line ;.r :1- of Fig. 2. Fig. 4 is a detail perspective view of one of the jaws. Figs. 5 and 6 are detail perspective views of the dies employed.
Similar reference-numerals indicate correln the embodiment ofthe invention as shown a body 10 is employed, having a cylindrical bore 11 therethrough and being provided in- .45
its opposite walls with sockets 12, opening into the/bore. The upper end of the body is counterbored to provide a seat 13 for the lower end of the feed-screw shank, (designated 14.); Hinged to one side of the body by means of pivot-pins 15 are jaws 16, which are arranged to swing into and out of the sockets 12, these jaws having angularly-dis 'iosed seats 17 arranged in their inner faces. Dies 18 are detachablylitted in the seats and are in the form of blocks having their opposing inner faces concave, as shown. and carrying sets of teeth ceive a punch by means of which the dies may be unseated, as will be readily understood. The free ends of the aws and the corresponding side of the body are provided with projecting lugs 21, having slots 22, which aredisposed in ahnernent when the aws are seated in the sockets. T the free end of one of the jaws is pivoted, by means of a pin :23, a locking-bolt 24, arranged to swing into the alined slots, said bolt being held in this position by means of a nut 25. As a result the jaws will be locked in their closed positions and the looking means will engage the body.
It will be apparent that when a drill-stem,
as 26, is titted in the bore 11 and the jaws swung to closed positions and locked the teeth '19 ot' the dies will engage said shank and hold it both against longitudinal and rotary movement in the body. This holding action is due to the arrangement of the sets of teeth at right angles to each other, as will be apparent. At the same time the ,dies cannot become displaced, as the stem will hold them in their seats. The drill can'be easily removed by unlocking the jaws and'swinging them outwardly, and when the teeth of the dies become worn said dies maybe readilydetached by inserting a punch into the openings and driving them from their seats.
It will be seen that the structure is made up of a few parts which may be readily assembled, so that the device can be manufactured at siight expense. Because of the arrangement ot the jaws fitting in the sockets the weight of the drill transmitted to the jaws the strain thereof.
' From the foregoing it is thought that the Q construction, operation, and many advantages of the herein-described invention will be apparent to tllOS skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and minordetails of construction may I be resorted to without departing from the spirit or sacrificing any of the ad vantages of the invention.
Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, isi 1. In a coupling of the class described, a body having a longitudinally-disposed bore and a socket communicating with the bore and having a bottom, a jaw pivoted at one end to the bottom and swinging into and out of the socket, the pivot-axis of said jaw extending longitudinally of the body, and means engaging the free end of the jaw to secure said jaw in the socket.
2. In a coupling of the class described, a
ing with the bore, and a jaw pivoted to the body and titted in the socket, the pivot-axis of said jaw extending substantially longitudinally of the bore.
3. In a coupling, the combination with coacting pivotally-associatcd jaws having seats in their opposing faces, of dies detachably fitted in the seats and having teeth on their opposing inner faces said dies being stationary with respect to the jaws, the teeth upon one of the dies being disposed longitudinally of the jaw and those on the other die being arranged transversely of the jaw.
4. In a coupling of the class described, a body having a bore and oppositely-disposed sockets communicating with the bore. oppositely-swinging jaws pivoted to the body and swinging into and out of the sockets transversely of said bore, and means for securing the jaws in the sockets.
5. In a coupling of the class described, a body having a longitudinally-disposed bore, and oppositely-arranged sockets communicating with the bore, jaws titted in the sockets, each pivoted at one end to the body, said jaws body having a bore and a socket communicatswinging transversely of the bore, and means for securing the free ends of the jaws.
6. in a coupling of the class described, a body having a longitudinally disposed bore. a plurality of jaws pivotally mounted on the body. ,Ineans for securing the jaws against Z their pivotal movement, said jaws having seats in their inner faces, and toothed dies detach-.
ably titted in the seat. said dies being stationary with respect to the jaws holding the same.
7. In a coupling of the class described, the combination with a body having a longitudinally-disposed bore and o ipositely-arranged transversely-disposcd sockets communicating with the bore, of jaws pivoted to the body and swinging into and out of the sockets transversely of the bore, and a locking-bolt pivoted to one jaw and detachably engaging the otlxer to hold the jaws in the sockets, said bolt extending transversely of the body.
8. In a coupling of the class described, the combination with a body having a bore therethrough and sockets extending through its opposite walls to the bore, of jaws pivoted to the body and fitting in the sockets thereof, and a locking-bolt pivotally connected to one jaw and detachably engaging the other.
9. in a coupling of the class described, the combination with a body having a bore. therethrough and sockets extending through its opposite walls to the bore, of jaws pivoted to one side of the body and fitting in the sockets, and a locking-bolt pivotally connected to the free end of one jaw, the other'jaw and the body having alined slots arranged to receive the bolt to hold said jaws in the sockets.
10. In a coupling of the class described, the combination with a body having a bore the!" through and a socket extending vto the bore, of a jaw hinged to the body and iitting in the socket, said jaw having in its inner face a seat and an opening extending to the seat, a die titted in the seat, and teeth carried by the die and pr jecting into the bore of the body.
In testimony that we claim the foregoing as our own we have hereto aiiixcd our signatures in the presence of two witnesses.
