This invention relates to an illusion novelty.

One of the objects of this invention is to provide an illusion novelty consisting of an artificial tooth and simulated dentalforceps which-will give the impression that the forceps were used to extract a natural tooth from the mouth of a person.

Another object of this invention is to: provide an illusion novelty whichsimulates thecondition of a tooth extracted by dental forceps- This. invention is to be used. in such a. manner as to simulate in a realistic. manner the extraction of a tooth. The forceps ina closed position with the artifieial tooth hidden from: View areinserted in the mouth so that the jaws. of the forceps arenotvisible. The forceps are manipulatedsothatthe'jaws of the forceps open and the artificial tooth moves forwardly to an exposed position between the jaws of theforceps inside the mouth. The forceps are thenremoved fromv the mouth, giving the appearance that the tooth has. been extracted. This will create the illusion of a natural condition, namely, that of. extracting a tooth and will surprise and perplex the viewers which will turn: toxamusement when apprised of the true situation.

Other objects will become apparent as this description progresses.

The structure shown in Figures 1 to 8 inclusive will be first described. The structureshown may be formed preferably of. plastic material and: comprises simulated forceps having a pair of members generally indicated at 10 and 12 pivotally secured together. The member 10 has a head generally indicated at 14 having a forwardly extending jaw 16. The portion of the head rearwardly of the jaw has two spaced walls 18 which continue rearwardly to form the handle of member 10.

The other member 12 has a head portion generally indicated at 20, having a forwardly extending jaw 22. The portion of the head 20 rearwardly of the jaw 22 is 2,953,314 Patented Sept. 20, 1960 reduced. to provide a pair of spaced walls 24 which continue rearwardly to form the handle of member 12. The walls 24 of head 20 are confined within the spaced walls 18 of head 14. The. two members 10 and'12 are pivotally secured together by pins 26 which also support atubular member to be described. 7 I

Supported'betweenthe walls 24of head 20 is a tubular member generally indicated at 28. The tubular member 28. is secured in position by the pins 26 which extend into suitable openings 29 in member 28. The pins 26 may be formed integrallywith the walls 24 extending outwardly into walls 18 and inwardly into the openings 29. in tubular member 28.

The lower end of tubular member 28 is closed to re: ceive a. coil spring 30. Slidingly supported in the. tubular member 28 is a stem 32, the lower end of which is positioned inside thecoilspring 30. ,The stem 32 carries a cross pin '34. which engages the spring 30 which normally urges the stem 32 upwardly. The tubular member has a guide slot 36 forthe cross pin 34'. Secured to the opposite end of stem 32 is a simulated or artificial tooth 40. which is positioned sothat the root part of the tooth faces outwardly and same is colored red to simulate blood. The stem 32 is formed of a transparent plastic material so. that same is not readily visible to the eye. The insides of the jaw members 16 and 22 are hollow and provide a housing for receiving the tooth 40 in retracted position as shown in Figure 4 so that when the jaws 16 and 22 are closed the tooth 40 is not visible from the outside. In this position the major portion of the stem. 32 is. positioned inside the tubular member 28 against the compressed spring 30. When the jaws 16 and 22 are openedsuflici'ently to allow the tooth 40 to pass therebetween, as shown in Figure 5, the spring 30 will push the stem outwardly to move the tooth to the position shown in Figure 5. The stem 32 is limited from further outward movement by engagement of the cross pin 34 with thetop of guide slot 36. By holding the jaws 16 and 22 in the position shown in Figures, 1 and 5 it will appear that the jaws are gripping the tooth-40 as though same wasextracted from the persons mouth. To retract thesimulated tooth '40, the jaws 16 and 22 are opened sutficiently to allow the tooth 40 to pass therebetween, after which the tooth 40 is manually pushed inwardly so that the stem 32 moves inwardly into the tubular member 28'. and by closing the jaws 16 and 22 through the handles of members 10 and 12 the simulated tooth 40 is retained. inside the jaws in retracted position as shown in Figures 4 and 6.

Figures'8 and-9 show a modified construction in which the simulated. tooth is. automatically retracted when. the forceps are closed. Since the construction heretofore described in Figures 1 to. 7- is the same as in Figures 8 and9, same will not be redescribed, the modification only will be described. To the inside of the handle portion of member 12, an arm 44 is pivotally secured as at 46; The army extends downwardly and the opposite end of-the arm is confined in the hollow interior of the handle portion of member 10 to ride up or down therewithin, dependent on the positions of members 10* and 12. A cord '48 has one end attached to the arm 44 as at 50 and the other end attaches as at 52 to the stem 32 on which the simulated tooth 40 is secured. For the purpose of attaching the cord 48 to the stem 32 a suitable opening is provided in the bottom of the tubular member 28 so that the cord can pass through same. When the forceps are in open position the parts will be as shown in Figure 9, since with the jaws separated the spring 28' will urge the stem 32 upwardly to expose the tooth 40 and through cord 48 pull up arm 44, however, when the members 10 and 12 are moved towards each other as in closing the forceps, the arm 44 will ride down on the handle portion of member and the the stem 32 and tooth 40 downwardly against the spring 30 so that the tooth is confined within the jaws of the forceps. When the members It). and 12 are separated as in Figure 9, the arm '44 will ride up the handle portion of member 10 and the tooth 40 will be positioned as shown.

Figures 10 and 11 show another modification. To each of the handle portions of members 10 and12 there is pivotally secured as at 56 and at 58, links 60 and 62 respectively. The two links being pivotally joined as at 64. A stiff wire 66 is connected at one end to the stem 32 which supports the simulated tooth and at the other end to the two links at their pivotal connection 64. With the use of a stiif wire the spring '30 in member 28 may be eliminated. j

The amusement resides in making it appear that a tooth is being extracted, thus providing surprise and amazement. -The simulated forceps in closed position are put into a persons mouth and when in the mouth, the jaws of the forceps are opened so that the simulated tooth is moved outwardly by the spring 30 in Figures 1 to 9 inclusive and by the wire 66 in Figures 10 and 11. The jaws of the forceps are then brought adjacent the tooth 40. In this position the forceps are moved out .of the mouth, giving the appearance that a tooth has been extracted from the mouth.

It will be understood that various changes and modifications may be made from the foregoing without departing from the spirit and scope of the appended claims.
