DENTAL PLTERS.
Specification of Letters Patent.
Patented Aug. 2, 1921.
Application led July 29, 1920. Serial No. 399,757.
Y sirable and accuracy and application necessary. The improved pliers have been devised with the object of simplicity in structure and sensitiveness in resilient action, and to accomplish these advantageous features of devices of this class, the improved pliers are formed from a single piece of metal intermediately bent to provide opposing jaws which are reduced in thickness from a point slightly in advance of the bend to reversely bowed portions of the jaws and terminated at the free ends of the jaws in laterally and obliquely projected beaks which contact only at the pointed ends thereof. The improved pliers are also so constructed that when the jaws thereof are tightly gripped to close the beaks relatively to a piece of material or a device therebetween, the strain of the compression instituted by the grip of the user will be largely removed from the bend of the pliers and transferred to a point of contact of the opposingjaws in advanceof the bend a certain distance, to thereby render the resilient action of the jaws relatively to the primal resiliency thereof more durable, or, there will be le/ss deterioration of the resilient or spring action of the jaws in consequence of this bracing action in advance of the bend and the thin jaw parts which give the jaws a desirable resilient action when liberated. The jaws are also reversely bowed so as to provide for bringing the points of the beaks at the free ends of the aws in contact to increase biting action of the beak points relatively to the material or device that may be held therebetween. All the parts of the improved pliersare also free of grooves, recesses or crevices, and may thereby be readily sterilized fully from the bend to the beaks in view of the fact that the jaws have an opening extending therebetween from the bend to the beaks.
The improved pliers are illustrated in the accompanying dra-wing, and in the latter Figure l is a perspective view of the pliers shown open.
Fig. 2 is a side edge elevation of the pliers.
Fig. 3 is a view similar to Fig. 2 with the jaws and beaks closed.
Fig. i is a cross sectional View through the jaws at the rear portions of the beaks.
Fig. 5 is a perspective view of the improved pliers, showing the manner of using the same.
The improved pliers, as hereinbefore indicated, are formed from a single piece of metal which is suitably tempered to give the same an inherent resiliency. The strip of metal is centrally bent as at 5 to produce 0pposing jaws 6 which are gradually tapered asV at 7 and laterally and obliquely bent to provide opposing beaks 8 preferably having inner roughened Sides 9. The jaws 6 from the bend 5 a suitable distance forwardly are reduced in thickness by removing the metal at the outer sides to form spring connecting arms l0, the jaws 6 in advance of these arms being materially thicker, the thickened portion of the jaws continuing to the tapered forward extremities, the said extremities being gradually reduced in thickness as at 1l toward the beaks 8. rlhe jaws 6 are also reversely bowed, or each has an outward elongated bend which continues regularly from a point slightly in advance of the reduced spring connecting arms 10, these connecting arms l0, as hereinbefore specified, being the thinnest portions of the jaws and such reduced thickness of the latter is continued through the bend The bowed construction of the jaws 6 together with the reduction of the jaws to form the spring connecting arms l0 provide for a bracing Contact of the rear portions of the aws in advance of the front terminals of the arms l0 or about at the point l2 when these jaws are closed by compression to grip a piece of material or device that may be disposed between the beaks 8. This bracing contact of 'the j aws prevents the spring connecting arms 10 and the bend 5 from being subjected to the full compressing strain exerted on the jaws, and, as a consequence, the said connecting arms l0 will be rendered more durable and their resilient action will be prolonged and be less liable to deteriorate from tact portion of the jaws above noted, varyj ing sensitiveness of touch to suit the perusage of the pliers. `When the jaws are released or relieved of gripping compression, the connecting arms 10 will instantly separate the jaws and said resilient arms will also similarly operate the'moment that the least relaxation of compression on the jaws ensues.
This sensitive action of the connecting arms and the bracing action relatively to said arms when the jaws are'compressed to reduce the strain on the bend 5 is of material advantage in dental operations where Va light weight instrument of a sensitively resilient character is necessary in performing dental work andin handling certain materials. It will be seen that when the jaws are closed as shown by Figf, from the point of contact l2 the arms l0 are separated by a' gradually diverging space toward the bend 5, and by enlarging or decreasing this space between the bend and the bearing or consonal performance of a dentist may be produced. y
It will also be observed that the improved pliers are smooth or are devoid of crevices or angles for the lodgment of impurities, and, moreover, the jaws are fully open from the bend to the beaks, and as a consequence a thorough sterilization thereof may be easily "effected All rivets vor connecting devices requiring expense in manufacture are avoided in the construction of the pres-v bowed and havingreduced extremities terminating in laterally and obliquely project ed beaks which contact at their points only, the metal adjacent ,to and at a certain distance from the bend being reduced in thickness to provide resilient connecting arms between the jaws. and bend, the jaws being fully open between the bend and beaksV thereof andihaving contact in advance of the said connecting arms when theV jaws are compressed and closed to relieve the bend and arms of deteriorating strain. v Y In testimony whereof I have hereunto set my hand in presenceof two subscribing witnesses.
