WOODBURY STORER HOT/V, OF PHILADELPHIA, PENNSYLVANIA ASSIGNOR- TO THE S. S. WHITE DENTAL MANUFACTURING COMPANY, OF SAME PLACE.
TEETH-SEPARATOR.
SPECIFICATION forming part of Letters Patent No. 513,016, dated January 16, 1894:.
Application filed November 1 s. 1893. Serial No. 490,813. (No model.)
To all whom it may concern:
Be it known that I, WOODBURY STORER HOW, a citizen of the United States, residing 1n the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania,'have invented certain new and useful Improvements in Teeth-Separators; and I do hereby declare the following to be a full, clear, and
enact description of the invention, such as w1ll enable others skilled in the art to which it appertains to make and use the same.
My invention relates to certain improvements, as hereinafter claimed, in separators such as employed by dentists for forcing apart or lncreasing the space between proximal teeth and for keeping them suitably separated during treatment or operations performed thereon.
Separators of the class to which my improvemen ts relate are shown in United States Patent, No. 15t,867, granted to Oliver A. J arvls, September 8,1874, and No. 866,025, granted to Safford G. Perry, July 5, 1887.
The objectof my invention is to providea separator having a wider range of adjustment than those heretofore employed and adapted for use upon proximal teeth of varying sizes, and in any location in the month.
In the accompanying drawings which show a suitable embodiment of my invention, Figures l and 2 represent, respectively, a plan and an elevation of a separator as applied to central incisor teeth. Fig. 3 is a plan view of the separator as applied to the largest poster 1or teeth. Fig. 4 is a detail view in perspect1ve, on an enlarged scale, designed to illustrate means for adjusting the separator. Figs. 5 and 6 show, respectively, a View in perspective and a sectional view of a modification of the adjustable connection between the bow sections; and Fig. 7 a view in perspective of another modification of said connection. Fig. 8 is a View in perspective of a modification of the adjustable connection between the bows.
A pair of sectional bows, each consisting of two parts adjustably connected, are provided as fo1lows:-The parts A A of one bow have each a curved separating jaw a a for engagmg with a tooth at or near the surface of the gum and the parts BB of the othersectional how are likewise provided with separating jaws b b for similarly engaginga tooth nextthat engaged by the jaws a a. The two sections A A and B B of each bow are bent or curved so that the inner or adjacent ends of the sections of the respective bows are made to project beyond the crown ends of the teeth with which they may be engaged and these ends of the bow sections are provided with tapped holes or female screws by way of which the two sections of each bow are respectively adjustably connected by means of screw bars,
the screw bar 0 connecting the sections AA of one bow, and the screw bar 0 connecting the sections B B of the other bow. These screw bars are each provided with two-way threadsthat is, with a right hand thread at the bow sections occupy positions clear of the teeth with which the separator may be engaged, as will be seen by reference to Figs. 1, 2 and 3, in which D D represent incisors and D D posterior teeth.
The outer ends of the sectional bows A A and B B are provided with tapped holes or female screws which are engaged by screw bars E E, these screw bars being provided with two-way threads (a right hand thread at one end and a left hand thread at the other) by means of which the bows of the separator may be spread apart or caused to approach each other as in the Perry separator hereinbefore mentioned.
In operation the separator is adjusted upon any two proximal teeth as desired by manipulating the adjusting screws 0 O by means of a lever F engaging holes f in the screw bars, or by a screw driver engaging the end nicks in the screws, and when the sections of the respective bows are adjusted toward each other sufficiently to tightly engage the teeth by the separating jaws the screw bars E E- are turned by a lever or screw driver so as gradually to spread apart the teeth as will readily be understood.
By my improvements it will be seen that the one device having the sectional adjustable bows may be used for engaging and separating either large or small teeth, incisors or molars, and be used successfully upon any proximal teeth in the mouth; and that the screws adjustably connecting the sections of the respective bows are out of contact with and project clear of the gums and teeth and are readily accessible for adjustment.
I do not wish to be understood as confining my invention in all respects to the details of construction hereinbefore specifically described, as it may be modified somewhat while still retaining essential features of my improvements. For instance, instead of the two-way adjusting screws 0 C, I may employ adjustable connections between the sections A A and B B5 of the respective bows, such as shown by Figs. 5 and 6, in which one of the bow sections is fast upon one end of a squared screw bar G, and the other section adapted to slide upon this bar which has rounded corners and is provided with a screw thread. A screw nut I-I adjustable upon the bar serves to move the adjustable section of the bow toward the fixed section and to hold tion, as will readily be understood. This construction it will be seen prevents the accidental displacement of the separator by overcoming the tendency of the bow sections to twist or turn when the separating jaws are acting upon the very sloping sides of some teeth. As shown by Fig. 7 the adjustable connection between the sections of a bow consists of the singly-threaded screw bar G upon which the bow sections are adapted to slide and the two screw nuts H H working upon the screw bar outside of its connections with the bow sections. In this way, as will be obvious, the sections may be drawn toward each other by turning the nuts. As shown by Fig. 8 instead of the two-way adjustable connections E E, the adjustable connections between the two bows (whether they be made in sections or each in one piece) may consist each of the singly-threaded screw bar I fixed at one end to one of the bows, with its opposite end passing freely through the other how, and provided with the adjusting nut J by which to spread the bows apart. Instead of having the screw bar I fixed to one of the bows, it may pass freely through both bows and an additional adjusting nut be employed as indicated by dotted lines Fig. 8. In this way each bow may be operated upon to move them apart. I
It is furthermore obvious that the members A G Fig. 5 may be constructed in one solid piece and so be integral in structure to constitute a modification of my invention as aforesaid.
I claim as my invention- 1. The combination of the two bows each composed of sections adjustably connected and provided with the separating jaws, and the adjustable connections between the bows by means of which they maybe spread apart,
substantially as set forth. it against movement away from the fixed sec- 2. The combination of the two bows each provided with the separating jaws, the screw bar passing freely through one or both of the bows, and the nut (or nuts) for spreading the bows apart, substantially as set forth.
In testimony whereof I aflir; my signature in presence of two witnesses.
