Specification of Letters Patent.

Application filed July 5, 1918. Serial No. 243,351.

To allwhom t may concern:

Be it known thatl,V JACOB LOWE YOUNG, a citizen ofthe United States, and resident of New Rochelle, in the v`county of Westchester and State of New York, have -invented certain new and useful Improvements in Orthodontia Appliances, (Case 2,) of which the following is a specification. This invention relates to improvements in orthodontia appliancesl or tooth-regulatingk and retaining appliances of the arch-wire type. Appliances ofthis Vtype .comprise a curved arch wire or delivery member vof approximately the same form as the dental arch, means for connecting the delivery member to a tooth orteeth to be treated,

and means for anchoring the delivery7 mem- Q ber at or adjacent its ends to suitable anchor teeth, such as molars. VThe movement of the malposed tooth or teeth to normal position in the Vdental arch is accomplished by'distending, shifting or contract-'- ing the arch wire orbar relatively to the anchoring means either by shifting the arch wire bodily relatively to the anchoring means by adjusting nuts threaded 'on the wire, as shown, for example, in the patent to Angle, No. 626,476, dated June 6, 1899,

or by altering the length of the arch wire by bending, crimping, or stretching the wire, as shown, for example, in the patent to Angle and Young, No. 1,005,131, dated A October 10, 1911.

. teeth.

The present invention has for one of its objects the provision of more efficient means for detachably locking the arch wire or delivery member to the anchor Ateeth and the malposed teeth. Y

Another object of the invention is to prO- vide means fory connecting the delivery member to the anchor teeth and the inal-A posed teeth adapted for use with either of the two types of appliances above desc'ribed` and a further object is to provide detachably interlocked means adapted for use to connect either an inside; or outside arch wire with the `anchor teeth and malposed Another object of the invention'is to pro- 5'0 vide coperating sets of separably interlocked devices carried ,by the arch wireand teeth, respectively, for positively but releas- Patented May 27, 1919.

ably locking the appliance in place in the.

mouth to prevent accidental displacement;

of the appliance, or removal of the appliance by the patient, especiallyk by children,

said separably interlocked devices being so constructed as to enable the appliance to be readily removed by the dental surgeon.

A further object is to provide interlocking connections between the arclrwire and the teeth, so constructed that thearch wire may extend around the arch in the same horizontal 'plane throughout its vlength and in planes different distances from the crowns of the teeth.' A f Another object of the invention is to pro-l vide cooperating sets of separably interlocked devices yheld to the arch wire .and

teeth, respectively, and so constructed that the devices will not engage the guml whenV interlocked; and still another vobject is to provide positively but separably interlock-` ing devices so constructed as'to'insure.v firm and rigid connections between the arch wire and the teeth and to prevent relatively lateral movement between thel coperating interlocked devices.

In the. drawings, Figure l is `a plan view of the appliance mounted on the teeth, showing one embodiment of the invention;

Fig. 2 a fragmentary side elevation;

Fig. 3 a detail view of a band adapted to be bent around a malposed tooth andl secured thereon by soldering its overlapped ends together, said band havingA soldered thereon the female member of' the interlocking connection vby which the arch wire 7 a vertical sectional view taken onV a detail perspective view ofthe d Fig. 8a view similarto Fig. 4-showing the interlocking connection between the arch wire and the band on a malposed tooth;

Fig. 9 a plan view of the Vconnection shown in Fig. 8;

Fig. 10 a vertical section taken on the line X-X of Fig. 8; and l Fig. 1l a plan view, partly in horizontal section, showing the mannerv of anchoring the arch wire when a tube and adjusting nut is employed for altering the length of the wire.

Referring to the various parts by numerals, 1 designates the metal bands fitted about the malposed teeth and 2 designates the usual anchor bands fitted about the molar or anchor teeth. The anchor bands 2 each have soldered or otherwise ksecured thereto the female member 3 of a separable connection. The female or socket inember comprises a back plate 4 soldered .to band 2 and bent to form inclined side walls 5 and vertical flanges 6 parallel with and spaced from the back plate. The lmember 3 thus formed provides a tapering socket, as clearly Vshown in Figs. 4 and 5, the front wall of which is slotted vertically throughout its length at 7. The male member 8 of the anchoring connection ycomprises a spring metal plate doubled -upon itself to form a back Ymember 9 and a front member 10, tapering from their upper ends to their lower ends and having their free lower ends normally spaced apart, as clearly shown in Figs. 6 land 7. The front portion 10 is provided with a vertically extending central rib 11 and the adjacent end of the arch wire or delivery meinber 12 is soldered to said rib at any desired Vpoint along the rib. 'The outer face of the front portion 10 of the member 8 is cut away along each side of the rib 11 from a point adjacent the free lower end thereof to a point adjacent its upper end, to form bev eled surfaces 18 and shoulders 14. It will be obvious that by pressing the portions 9 and 10 of member 8 together and forcing the same downwardly through member' 3, the free ends of said portions will spring apart as soon as shoulders 14 pass the lower ends of flanges 6 until the beveled surfaces 18 en gage the inner sides of said flanges, whereupon the shoulders 14 will engage under the lower ends of the flanges and lock members 3 and 8 against separation. During the act of interlocking members 8 and 8, and after said members are interlocked, the rib 11 projects outwardly through the slot 7 and the arch wire 12 lies outsideofthe member 8.

The arch wire or delivery member 12- comprises a stiffl spring wire or bar curved or bowed to approximate the curvature of the dental arch, and has soldered thereto at the proper point or points the male members l5 of coupling devices for connecting the arch wire with the bands 1 tted about the malposed teeth. rihe members or posts 15 are formed of resilient metal and are preferably relatively flat in VVhorizontal section, the lower portion of each post being bent outwardly, as shown in Fig. 10. The posts 15 gradually decrease in width from their upper to their lower ends, and the side edges thereof are beveled as shown at 16. The rposts 15 are formed with vertical central ribs 17 on their outer faces and Athe arch wire or bar 12 is soldered to said ribs at any suitable or desired point along the length of the ribs. The outer face of each post is cut away alongeach sideof rib 17 to form shoulders 22 and beveled or inclined surdecreasingin depth towardzthe upper ends of the posts. Downwardlfy tapered female or socket members 18 `are soldered to Ythe bands 1, said `members @being 'of substantially the same construction :as fthesooket members 8, and comprisingl a :metallic plate `benttoasshown more clearlyin Figs. 8 and. 9, and Y the adjacent edges 'ofllanges- 2O are spaced apa-rt yto provide .anv `'opening-orvertical slot 21 extending throughout ithelength of thek socket member. Y

The members land 18are-interlocked by forcing the member l5 .downwardly into member 18, the'rib 117 onimember j18 passing through the slot 21 andthe arch wire 12 passing down along the-outer sides of flanges 20, as shown lin Figs. 8 to l0. Duringthe downward ino-vement Yof post =15 the out-` positively locking the coupling members 15V and 18 together.

The anchor lock above described `may also be employed in an appliance of the type heretofore described in which the arch wire or delivery member is supported at its ends in anchor tubes and is adjusted by means of nuts 'threaded on the arch'wire land engaging the tubes. Vhen so employed, 1 prefer to solder the back plate4 of the socketmember-3 to the anchor band 2 and solder the anchor tube 24 at the desired point along rib 11 on the fronty portion 10 of male inember 8, as shown in Fig. 11. With this construction it will be observed thatthe Vanchor tubes 24, arch'wire' 12, andadjusting nuts 25 may be removed bodily inassembled relation from the mouth vwithout the necessity of disturbing the adjustment ofthe nuts 25 on the arch wire.

The tapered formation of the male and socketmembers o-f the interlocking connections prevents lateral movement between the members and insuresa firm and rigid connection between the arch Wire and the teeth.

The interlocked members 3 and 8 may he readily separated by pressing the lower end of the front portion of member 8 inwardly by means of a suitable implement and pulling upwardly on the arch wire 12. The members 15 and 18 may be readily separated by pressing the outwardly bent lower end of member 15 inwardly and pulling up' wardly on the arch wire.
