Application filed November 12,l 1914 Serial No. 871,672.
T all whom t may concern:
lar abrasive,
. Be it known thatI, HENRY G. DnEssEL, a citizen of the United States, residing in Chicago, in they county of Cook and State of Illinois, have invented certain new and useful Improvements in Dental Tools, of which thefollowingisa specification.
Primarily, this inventionrelates to dental tools and has for its object,the provision of a readily adjustablepmeans for the attachment of sand paper or emery disks or simigrinding or buHng elementsy to the chuck of a standard dentalengine.
`W ith the above and other objectsin view, this invention consists in the'construction, combination and arrangement of parts, all
. as hereinafter more fully described, claimed A and muse-atea in the accompanying drawing Wherein- Figure l is a central longitudinal section of the present invention illustrating the same in its operative position and performing its designed functions. Fig. 2 is a similar view of a modified form thereof. Fig. 3 is an elevation of the tool illustrated in either Figs. 1 or 2. Fig. 4 is a transverse f section taken along line 4-4 of either Figs.
1 or 2, being an elevation of the outer end of the tool illustrating the means whereby the abrasive or grindingdisks are secured thereto. Fig. 5 is a horizontal section `taken along 5 5 of Fig. 1 and illustrates a locking j mechanism, said mechanism also being present in the form shown in Fig. 2.
Reference being had more particularly to the drawing, 10 indicates the chuck of 'a standard dental engine having the usual eX- teriorly threaded spindle 11, whereby tools and the like may be attached thereto.
The present invention residesl in atool designed for attachment to the threaded portion of the spindle l1, through the medium of which the abrasive or buliing disks may readily be attachedr to and detached from said chuck. This tool consists of a two part casing comprising thebase 12 yand the barrel 14, which, as Will be 'hereinafter described, are detachablyconnected, the said base 12 having its outer end tapered as at 13 and provided with a concentric interiorly threaded socket for the reception of the threaded portion of the spindle 11. At its outer end 18 no access may be had to the interior of the base 12, While the opposite or inner end is open forming a connection with the passage 16, concentric'ally arranged in the base. The inner end of the base 12 Vis surrounded by an exteriorly threaded tubular projection 12a of lesst diameterthan the casing, whereby barrel 14 may be attached to said base 12 as will be hereinafter'more particularly pointed out.
The barrel 14 is of equal exterior diameter to the base 12 and has its inner end interi'orly threaded for locking engagement with the tubular projection 12a of said base. A p assage 17 extends partially through fthe barrel '14,said passage having a contraction 18 adjacent toits outer end to which the Wall of the 'passage 17 tapers as at 19. The contraction 18 is apertured, as at 20, to form Aa continuation of the passage 17, which ap- To'form a support for the abrasive disks` 22, the'outer terminal of the barrel 14 surrounding the counter sink 21 is, provided with an outstanding concentric flange 15, from which projects a plurality of pins 23. The abrasive disks 22 rest Hush upon the flange' 15Eand are provided with openin s to receive-the pins 23, thereby attaching said disks securely to the tool for rotation therewith.
For the purpose of preventing the abrasive disks 22 from fallingv away from the tool, aclamping plate 24 is provided, having a central shank 25 on its inner face. This clamping plate 24 is provided with a peripheraly lip 26 projecting transversely therefrom and upon the same side thereof as the shank 25.` The diameter of this lip 26 is equal to the diameter of the iange 15. The shank is inserted in thecounter-sink 21 `and the' passage 2O and projects into the soi ried by the tool and forms4 a housing yfor the pins 23 of the flange 15 and when said shank is locked in this position, the abrasive disk 22 is securely held by the clamping plate.
In order to -lock shank 25 in the barrel 14, a locking cylinder 27 is mounted for reciprocation in said barrel terminating at its upper end in the tapered head 28, the taper of said head conforming to the taper 19 of the passage 17 in said barrel. This locking cylinder is provided with a bore 29 extending completelythrough, in which the shank to the cylinder.
ting of the pin 31, the cylinder 27 isapertured at 32, diametrically opposite to the pin 31, and the base 12 is likewise apertured as at 33 for registration with the aperture 32so that when the parts are vpositioned as "in Figs. 1 and 2, the inner end of thepin vmay be reached.
To normally force the tapered head 28 against the tapered surface 19 of the'passage 17 in the barrel 14, a spring 34 is provided in the form shown in Fig. l between the head 28 and thev upper terminal of `thei base l2 and encircles the body of the cylinder 27. In Fig. 2, the spring 34a is locatedL between-the bottom of the passage 16 in the base 12 and the lower terminal of the cylinder 27 andv performs the function of vforcing the tapered head v28 of the said cylinderV against the tapered portion 19 of the pasy sage 17 inthe barrel.
aperture or passage20.
When it is desired to release theclamping The tapered head 28 of the locking cylinfy der: is provided with a plurality of horizontalradial ball races 35 which extend from the exterior tapered surface of the said head to the passage or bore 29, extending through Athe cylinder 27 and the'head 28 thereof.
Each ball race is .provided with a locking ball 36 as illustrated in Fig. 5.
`JvVhen the shank 25 is inserted in the aperture 20 and into the passage or bore 29 of the cylinder 27, it contacts with the balls 36 and forces the cylinder 27 against the action ,of the spring 34, 34L andthe head 28 away from the tapered wall 19 of the passage 17 thereby permitting the balls 36 to move outwardly in the ball races 35. When the pressure is removed 'from the shank 25, the
head of the pin 31 is forced downwardly into slot 30, thus moving the head 28 away from. the taperedwall 19 of the passage y17 y allowing the balls to move outwardly in the ball races 35, andaway from the shank.
To accomplish the upset-v clamping plate coperating with said means and provided with a shank arranged to be received within said casing, a'spring actuated locking cylinder mounted for reciprocation in said casing forlocking the shank against movement, and means for moving said 4cylinder free from the exterior of the casing and against `the action of the spring aforesaid.
, 2.,-The combination kwith a casing having a passage therein provided at one'end with an apertured contraction to which the wall of said passage tapers, of a locking cylinder mounted for reciprocation in the casing aforesaid and provided with a passage extending therethrough, a tapered head formed on said cylinder and having radiating ball races therein, ball in lsaid races, and means for forcing the cylinder and its tapered head toward the taper in the wall of the passage of the cylinder.
3. The combination with a casing having a passage therein provided at one end with an apertured contraction to which `the wall of said passage tapers, of a locking cylinder mounted for reciprocation in the casing aforesaid and provided with ya passage extendingl therethrough, a tapered head formed on said cylinder and having radiating'ball races therein, ball in said races, a
spring interposed between the cylinder and the casing for forcing. the former and its tapered head toward the contraction aforesaid, means for moving the cylinder against the action of said spring, a shank carrying a clamping plate arranged to enter the aperture of said contraction and extend into the passage of the cylinder'where'it is clamped by the balls aforesaid when the said cylinder is acted upon by said spring.
In testimony whereof, I have Vvhereunto set myl hand vand aflixedk my seal this 10th day of November, A. D. 1914. f
