ANGLE ATTACHMENT FOR DENTAL ENGINES.
SPECIFICATION forming part of Letters Patent No. 319,583, dated June 9, 1885.
Application filed January 30, 1884. (No model.)
To all whom it may concern:
Be it known that we, WILLIAM A. J OHN- STON, of the village of Clifton, in the county of Richmond and State of New York, and
ARTHUR W. BROWNE, of the village of Westficld, in said'county and State, have jointly invented certain new and useful Improvements in Angle Attachments for Dental Engines, of which the following is a specification.
Our invention relates to tool-carrier attachments for the hand-pieces of dental engines of that class known as right-angle attachments, which are adapted to carry burrs,
disks, drills, and other revolving operating tools, so as to operate at an angle to the longitudinal line of the hand-piece.
The object of our invention, more particubest way lIlOWkIlOWIl to us, Figure 1 is a view in elevation of the attachment, and Fig. 2 a longitudinal section thereof. Figs. 3, 4, 5, 6, 7, and 8 are views of the parts making up the attachment, detached or separated. Fig. 9 is a View of the rear end of one form of the shaftconnection with the rotary tool-holder of the dental engine hand-piece; and Figs. 10 and 11 are cross-sections thereof on the lines 10 and 11, respectively, of Fig. 9. Fig; 12 is a similar view to that, of Fig. 9 of a differentlyconstructed connection at the end of the shaft of the attachment, with which the locking devices of the spindle of a hand-piece are engaged when the attachment is in operation;
and Figs. 13 and 14 are transverse sections thereof on the lines 13 and 14, respectively, of said Fig. 12. Fig. 15 is a sectional view of a pair of forceps or pliers organized for the purpose of inserting and securing the tools in the angle attachment and of re moving them from the tool-holder thereof. Fig. 16 is a plan of said forceps; and Figs. 17 and 18 illustrate, respectively, the manner of removing the shank of the bit or tool from the tool-holder of the attachment and of inserting the shank of the tool in such toolholder; and Figs. 19 and 20 are sections through the front end of the attachment, showing organizations for driving the operatingtool at different angles.
A tubular sleeve, A, forming the main portion of the attachment, is fitted on the hand piece of the dental engine when the attachment is to be employed. This sleeve A is fitted with bearings for a shaft, B, the rear end of the shaft being provided with a notched or driving end, I), which, when the sleeve A is fitted on the hand-piece, is passed into the socket in the hand-piece tool holder or spindle, and is engaged by-the locking device of said spindle, so as to be revolved when. the handpiece spindle is revolved, as is customary in the construction of angle attachments for dental engine hand-pieces.
The driving end I) of the shaft B of the attachment may be constructed as shown in Figs. 2 and 4, which is a well-known form of look ing and driving end; or it may be constructed as in Figs. 9 and 12, which are also well-known ways of constructing the looking or driving ends of shafts or tools, so as to be engaged by the tool-locking devices of certain well-known 'forms of hand-pieces now in use and put upon the market by the S. S. White Dental Manufacturing Company, of Philadelphia, Pennsylvania. Of course the driving end of the shaft B, which is to be engaged and driven by the tool-holder of the hand-piece, may be constructed so as to fit the socket and tool-locking devices of any hand-piece desired, those forms illustrated in the drawings being adapted for hand-pieces in common use, as before stated. The front end of the shaft B of the attachment is provided with a bevel-pinion, O, fitted in a recess, (1, of the attachmenthead D. This attachmenthead D is preferably divided or .made of two sections, as shown in Figs. 7 and 8,which, when placedtogether, may be screwed into the front end of the sleeve A, as shown in Figs. 1 and 2. The screwthreaded shank d of the attachment-head is provided with a bearing for the front end of the shaft B, and, furthermore, is provided externally with a cone-surface, d, to fit the corresponding conically-socketed mouth a of the sleeve A, by which construction, when the attachment-head D is firmly screwed into the front end of the sleeve A, it will be securely held thereto and virtually constitute a single piece with the sleeve A. Bearings d d are formed in the head D of the attachment at a right angle, for instance, tothat of the shaft B, and these bearings are fitted to receive the journals of the tool-holder F of the attachment. This tool-holder Fisa tubular. spindle open at both ends, andis provided with or surrounded by a rigidly-attached bevel gear or pinion, f, fitted in asocket or recess, d, in the Figs. 2, 6, 17, and 18-that is to say, with a tapering or wedge shank, g, an enlargement or shoulder, g, and an operating end, 9'. The shanks of the bits or tools are held in the toolholder F of the attachment, and drivenrfir-mly thereby by means of friction, the tapering shanks of the tools being forced into the end of the tool-holder, as clearly shown in Figs. 1 and 2. v
. In order to provide for the ready insertion and removal of the bits or tools from the tool-holder of the attachment, I have organized a pair of forceps, as shown in Figs. 15, 16, 17, and 18, one jaw or beak thereof having a punch or plunger, h, rigidly attached thereto, while the opposite jaw or beak is slotted, as at h, the slot terminating in an enlarged recess, h which recess islarge enough to permit. the passage through it of the shoulder g and shank of the tool, while the slot h permits the passage between it of the reduced portion of the tool in front of its shoulder while it is not of sufficient width to permit of the passage through it of saidienlargement g and the shank ofthe tool.
In ordertoinsert and look a bit or tool in the tool-holder of the attachment, the head ofthe attachment is passed between the outer ends of the forceps with the end of thebeak or jaw carrying the plunger h bearing upon the forceps, as shown in Fig. 18. By forc- 7o ing the handles of the forceps together it will now be obvious that the tapered or wedgeshaped shank of the tool will be forced firmly into thesocket of the tool-holder F, and will be securely locked therein, so that when drlven in operation firm connection with the tool 1s had.
' In order to remove the tool from the toolholderF the head of the attachment is passed between the jaws to a greater extent than before, and sufficiently far to permit the entrance of the plunger h into the upper end of the holder F, and to bring the enlargement g of the tool in the enlarged recess W'of the opposite jaw. It will be obvious now that in closing the handles of the forceps the plunger or punch h will force the bit or tool out of the tool-holder, its escape being permitted through the recess h? of the opposite jaw,which jaw affords abearing for the lower end. of the tool-holder. It will thus be seen that the operating-tools of the attachment may be readily inserted in and are removed from i Y the tool-holder, as desired,while in operation a firm driving-connection is had.
Wedo not claim herein the improved forceps or pliers bywhich the tools are inserted in and removed from the angle attachment, as shown in Figs. 15,16, 17, and 18 of the drawings, as that device constitutes the subject matter of another application. filed by us as a division and continuation of this present case, said .divisional application having been. filed (at the demand of the Patent Office) April 19, 1884, as No. 128,576.
We claim herein as our invention 1. An angle attachment having a'sectional or divided head fitted with bearings for a tool-holder operating at an angle to the lorrgitudinal line of the attachment, and sald head having a reduced shank portion by which IIO itis attached to the'barrel or tube of the athand-piece casing, with a head carrying the tool-holder of the attachment, the combination of. said head with said sleeve or tube being effected by means of a threaded and cone connection, substantially as described.
4. The tool-holder of anangle attachment provided with a tapering tool-receiving socket. open at each end of the holder, and
with an external driving-gear forming part scribed our names this 22d day of January,
thereof, substantially as described. A. D. 1884.
5. The tool having a tapered or wedgeshaped shank, an enlargement or shoulder, 5" 5 and an operating end with a reduced portion between said shoulder and said operating end, Witnesses: substantially as described. OHARLEs W. WITHERS,
In testimony whereof we have hereunto sub- G. F. C. MEURER, Jr.
