UNITED. STATES JOHN J. MALONEY, OF ROCK RAPIDS, IOWA.

MEANS FOR EXTRACTING TEETH.

Application filed June 24,

To all whom it may concern. 1

Be it known that I, JOHN J. MALoNnY, a citizen of the United States, residing at Rock Rapids, in the county of Lyon and State of Iowa, have invented certain new and useful Improvements in Means for EX- tracting Teeth, of which the following is a specification.

This invention relates to a novel and improved means for extracting teeth, and is eswhereby teeth may be extracted by direct upward pull in line with direction of root growth, and by a greater force than is pos sible to apply by any other method now employed. 1

The prime object of the invention is to provide simple, durableand eflieient means for extracting'teeth, which means is adapted to impart increased power with less strength and effort on the part of the operator.

Further objects of this invention are to soconstruct my novel and improved means that a suitable steel plate formed of various shapes is placed over teeth next to the one to be extracted so as to cause no injury to the teeth; that the parts can be made of suitable material strong enough to make the forceps compact; that power is applied with the long axis of thetooth, thereby avoiding much friction that is caused by present methods, and permitting the' power to be applied in a steady and direct manner which tends to lessen the possibility of breaking the tooth or'fracturing the bone, and to so apply the force as to cause the least discomfort and disturbance to the patient.

The foregoingand such other objects as may appear from the ensuing description are accomplished by the construction, ar rangement, location and combination of the several parts hereinafter more fully described, illustrated in the accompanying drawings and particularly pointed out in the claims appended hereto, it being understood that slight changes in the precise shape, proportions and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings forming a part of this specification it will be seen that Figure 1 is a side elevation of the means embodying my invention.

Fig. 2 represent a plan view of the same.

. Fig. dis a plan showing the top handle disconnected.

Fig. 1 is a side elevation of a slightly modified form of lower handle disconnected. Fig. 5 is an enlarged side elevation of a slightly modified form of forceps discon- Fig. 1, my novel means is assembled in the position which'it normaly assumes when it is desired to extract a lower tooth. The numeral 1 designates the upper or top handle formed at one end portion thereof with an elongated opening 2 therethrough for'the reception of the forceps member '3, while the upper surface of the other end portion is serrated or roughened at 4 serving to prevent the accidental slipping thereof when in use, and said handle is provided near its inner end portion with a depending extension 5 having a rounded or ball like lower surface adapted to engage with asocket 6 formed in the upper surface and near the inner end of the lower handle 7, the inner end of said handle 7 being suitably connected with a steel plate 8, preferably lined with a soft metal 9, such aslead, or other desirable material, which plate is adapted to be placed over, and in contact with teeth next to the one to be extracted, said lining being adapted to prevent injury .to the teeth upon which it rests.

It will be perceived that the forceps member consists of three pieces; two beaks 10 and a rivet 11, the said beaks being so shaped as to fit various contours of the teeth, while the upper portion 12 of each beak is similar and is so curved upwardly and outwardly as to vary the proportion of pulling and crushing effect on the tooth to be extracted, since the pulling force shall always exceed the crushing effect of the beaks 10, said beaks being joined by means of the well known box joint with a rivet to act as a pivot, or by aplain joint such as used in an ordinary pair of shears.

In the slightly modified form of lower handle 13, shown in Fig. 4:, it will be seen that said handle is provided with an upward extension 14; formed with a socket portion 15 near the inner end of said handle forming a bearing for the reception of the extension 5 carried by the upper handle.

By the slightly modified form of forceps, such as shown in Fig. 5 it will be observed that the beaks 16 are joined with what is known as an ice tong joint, or a. joint that works on the principle of an ice tong joint.

It will be understood that the upper handle 1 is fastened to the lower handle by any suitable construction of bail and socket or ridge joint, and that the forceps are secured to the distal end of the handle by a toggle joint, or by a loop or cable (not shown); that the beaks 10 may be made in different shapes and patterns for the purpose of fitting any tooth; that the lower handle 7 may be secured to the steel plate 8 by a mobile joint, and that the handles 1 and 7 when pressed together at their outer end will open or spread apart at the short or distal end thereof;

It will be observed that the steel plate Sis formed with depending side portions adapted to overlap each side ofthe teeth upon which it is placed serving to always maintain the plate in its proper position with relation to the teeth.

The operation of iny improved means may be briefly described as follows The steel plate 8 is placed over the teeth next to the molar to be extracted, the upper ends 12 of the forceps are passed through the oval opening 2 in the handle 1 and the beaks of the forceps over the tooth to be extracted. when as the handles are gripped by the hand the opening 2 is caused to move upwardly in contact with the outwardly and upwardly curved surfaces of the ends 12 of the forceps, thus forcing the beaks 10 to close on and tightly grasp the tooth and additional pressure on the handle 1 imparts upward movement to the forceps which is grasped by said handle and extracts the tooth, which will be readily understood.

It will be readily obvious that 7 is the lower handle, (when used to extract lower teeth, or the upper handle when used to extract upper teeth), and that the opening 2 formed in the upper handle may be modified so as toengage' a toggle joint 'at upper end efforceps, or to engage a steel cable loop around the upper ends of the forceps. said loop fitting into'suitable notches in the upper ends of the forceps.

Havin'g thus described my invention what I claim and desire to'secure by Letters Patent is v 1; Means of the character described, comprising a handlewith an elongated opening formed through its inner endportion, and forceps reriioiialoly secured within said open ing, the upper inclined ends of said forceps being adapted to contact with the inner Walls of said opening.

2. Means ofthe character described, comprising a handle formed with an elongated opening at its inner end portion, and forceps formed with outwardly and upwardly curved members" adapted to be removably secured within said opening, said members being adapted to engage with the inner walls of said opening. l

3. Means of the character described, comprising an upper handle formed with an elongated opening at its inner end portion adapted to re'mcyably engage a pair of forceps, and a lower handle connected with said upper handle, and a plate connected tothe inner end of the lower handle adapted to embrace one or more teeth. I

l. Means of the character desc'ribe'd conr prising a handle formed with an elongated opening at its inner end, a forceps member removably secured within said opening. and a plate connected tothe inner end of another handle adapted to rest upon one or more teeth. v Y

5. Means of the character described, comprising a handle formed with an elongated opening at its inner end; the inner walls of said opening beingadapted to engage a pair of forceps, a second handle secured to the first named handle near its inner end by a ball and socket joint, and a plate connected to said second handle adapted to engage with a plurality of teeth, 7

6. Means of the character described, comprising a handle formed with an elongated opening at its inner end. the inner walls of said opening being adapted to remoyably engage a pair of forceps, a second handle secured near its inner end portion to the first named handle, and a steel plate provided with a softmaterial'lining connected to said second handle andadapted to engage a plurality of teeth.

7 Means of the character described. coinprising a handle formed with an elongated o 'iening therethrough at its inner end, and a forceps member provided with outwardly and upwardly curved upper portions adapted to detacha'bly engage with the inner walls of said'op'ening.

8. Means of the character described, comprising a handle formed with an elongated opening therethrough at its inner end, a forceps member having outwardly and upwardly curved portions adapted to r'emo'vably engage with the inner walls of said opening, and a steel plate connected with another handle adapted to be applied to a plurality of teeth.
