WITNESSES INVENTOR (fiqrles jig [Z612 CHARLES H. ALLEN, orrrrrsmmen, PENNSYLVANIA.
FLOATING TOOL-CHUCK.
To all whom it may 00mm Be it known that I, CHARLES H. AILEN, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Floating Tool-Chucks, of which the following is a specification.
This invention relates to improvements in drilling and boring apparatus and particularly to such type of devices adapted for drilling or boring polygonal holes.
The primary object of this invention is to provide a drilling or boring device of the type set forth for holding and operating a drill or cutting tool in such mannerthat the vibration of certain parts of the device will permit the cutting edge of the drill or tool to travel and operate in the path corresponding to the lines and angles of any polygonal figure.
Another important object of this invention is to provide a device of the character described which will operate the cutting tool eccentrically with respect to a piece ofwork.
Further objects of this invention are to provide a drilling or boring device of the type specified which is simple in its construction and arrangement, strong, durable and eiiicient in its use, readily set up for use, consists of comparatively few parts and inexpensive to manufacture.
To the accomplishment of these and such other objects as may hereinafter appear, the invention consists of the novel construction,
- combination and arrangement of parts herein specifically described and illustrated in the accompanying drawing, wherein is shown an embodiment of the invention.
In the drawing forming a portion of this specification and wherein like numerals of reference designate corresponding parts throughout the'several views:
Figure 1 is a side elevation of a device for drilling or boring polygonal-shaped openings in accordance with this invention, with a portion shown in cross section- Fig. 2 is a bottom View of the shank member.
Fig. 3 is a plan view of the locking ring.
Fig. 4: is a cross sectional view on the line 0JIJ, Fig. 3.
Specification of Letters Patent.
Fig. 5 is a top plan view of the drill member.
Fig. 6 is an end view of the driving element. a
Fig. 7 is a side elevation of the driving element. 7
Fig. 8 is a perspective view of the guide member.
Fig. 9 is a cross sectional view of the cutting tool on line y-y, Fig. 1.
Referring more in detail to the drawing there is shown in Fig. 1 a device for drillmg or boring polygonal-shapedv openings and comprising the shank member 1 flexibly connected to the drill member 2 by the interposed links 3. Y
The shank member 1 is formed integrally with the usual tapered shank 4 for chucking the drilling device in the machine, and the drill member 2 is provided with the chuck 5 for attaching the cutting drill or tool 6 to the drill member.
The lower portion of the shank member 1 comprises a circular disk 7 having a centrally disposed and integrally formed depending sleeve 8 which is provided with a rectangular recess 9, extending into the disk 7 for the purpose here'nafter described. The upper portion of the drill member 2 also comprises a circular disk 10 which has 12 formed therewith, member 1..
relative to the shank Rotation is transmitted by the shank member 1 to the drill member2 by means of the driving swivel 13, the heads 14 and 15 of which are adapted to engage in the rectangular recesses 9 and 12, respectively. The driving swivel 13, as illustrated in Figs. 6 and 7', is so shaped and constructed as to permit universal movement of the shank member 1 and the drill member 2 with the exception of rotation, as the heads 1 1 and 15, of the swivel, at the point of contact 16 with the walls of the rectangular recesses 9 and 12, are rectangular in cross section.
The lower face of the shank member disk 7, and theupper face of the drill member disk 10 are provided with the spherical depressions 17 in which are adapted to seat the enlarged spherical ends 18 of the links 3. The spherical ends 18, of the links 3, are
p PatentedNov.18,1919. Application filed March 16, 1918. Serial No. 222,815.
mounted and locked in their seats by the locking rings 19, which are provided with the key-shaped openings 20, permitting the passage of the spherical ends 18, and communicating with smaller spherical openings 21 which register with the spherical depressions 17 to complete the seat for the link ends 18.
The locking rings 19 are secured to the disks 7 and pass through apertures 22 in the disks, and which have a threadable connection through the apertures 23, in the-locking rin 19.
The shank member 1 and ber 2 are normally held in alinement and centered by the action of the spiral coil .spring'24' which embraces and incloses the disk portions of the shank member and the drill member, and the associated interposed parts.
The caps 25,
of the shank and drill members by the screws 26, overlap the ends of the coil spring 21' and hold the same in secured position.
It will be readily apparent that with the shank 4, of the device, fixedlychucked in a of the drill member will permit universal lateral movements to the drill member 2 relative to, the shank member 1, but no vertical movements, and that rotation may be efficiently imparted thereto, by the driving swivel 1'3, regardless of such lateral movements.
The drilling or cutting tool used in connection with the device herein described must necessarily be constructed for drilling polygonal holes, and the contours of the openmgs must be defined by employing a guide member provided with a polygonal opening identical to that to make. The drilling or cutting tool when operating upon a piece of workrequires one I vless lip or flute t of the opening: For example, when drilling a triangular-shaped opening having ply act as an the number of walls three -walls, b 'ut two lips or flutes are emm Figs. '1 and 9, has three lips or flutes 27 and is designed for drilling rectangularshaped openmgs.
The lips or flutes 27 are cut divide the periphery of the'body member 6 equa the chips or cuttings to pass out freely. The end of the cutting tool 6'or drilling member has lips or flutes whichconform with those provided on the cutting edge of the tool. The flutes or lips 27 on the'periphery of=the cutting tool simguides and follow the angularity of the polygonalshaped opening in the to radially of the drill guide member 28, which isshown in Fig. 8
as rectangular-shaped. Y Y
The guide member 28, having a polygonal shaped opening 29 10 by means of screws which v the flutes the drill memsecured to the disk portions,
which it is desired each other.
ly, anddeep enough to allow.
periphery and forms the consists of a flat plate and during the drilling operation the guide member is clamped .to the work,-which with the said guide member remains stationary and-the cutting tool 6 operates through the opening 29. During a boring operation the Wor with the guide member 28 revolves around the drilling device which in this instance is'fixedly held in the bormg machine;
The lateral shifting movements of the drill member 2 relative to the shank member 1 as hereinbeforedescribed, which forces 27 of the cuttingtool 6 to follow the contour of the polygonal-shaped opening 29 in the guide member 28 is well understood and does not require a more extended eX planation.
From the foregoing description taken in connection with the accompanying drawings, the advantages of the construction and the method of operation will be readily parent to those skilled in the art to which the invention appertains, and while describing the prlnciple of operation of the invention together with the device whichis now considered to be the best embodiment thereof, it is to be understood that the de- Vice shown is merely illustrative and that variouschanges in the form, proportion and the minor details of construction may be re-' sorted to without departin from the principlc or sacrificing any of t e advantages of the invention as defined in the appended] claims.
