FRANK F? CERNIGLIA Patented May 30, 1950 UNITED STATES PATENT OFFIC C(BNE ATTACHMENT FOR X-RAY MACHINES Frank P. Cerniglia, Monroe, La. Application October 20, 1947, Serial No. 780,916

6 Claims. 1 The present invention relates to cone attachments for X-Ray machines for use in dental surgery particularly, but also for such machines in general as used in hospitals, veterinary surgery and for other medical treatments.

The object of the invention is to produce more accurate and detailed radiographs by providing a more eificient cone for the X-ra machine than known types now in use, and to facilitate an accurate positioning of the machine whether level or tilted and target distance is increased from 8 inches to 20 inches.

To such end, the invention provides a cone with indicator means for accurately centering the apex end of the cone relatively to a target, said means being comprised in which thin flanges disposed at opposite sides of the point of the cone, by means of which it is possible to train the cone on the target, particularly with increased target distance, more or less in the manner of aiming a rifle.

In the drawing, like references refer to the same details in the difierent views.

The objects and advantages of this invention will be readily understood from the subioined description aided by the attached drawing:

Figure 1 is an elevational view of a diagrammatic character illustrating a cone constructed in accordance with an embodiment of the invention and in applied position;

Figure 2 is an enlarged view partly in section and partly in elevation of the cone as comprised in Figure 1;

Figure 3 is an elevational view of the cone and at right angles to Figure 2;

Figure 4 is a large fragmentary sectional view taken through a marginal portion of a wing;

Figure 5 is a view similar to Figure 4 showing a slightly modified structure;

Figure 6 is an elevational View of a cone in accordance with a further embodiment of the invention;

Figure 7 is an elevational view of the lower por-, tion of the cone as comprised in Figure 6 and substantially right angles thereto;

Figure 8 is a side elevation view of a cone constructed in accordance with a still further embodiment of the invention;

Figure 9 is a view in bottom plan of Figure 8;

Figure 10 is a view in perspective of another embodiment;

Figure 11 is a view in side elevation of the cup of Figure 10 in applied position, the associated portion of the tube of the machine being in fragmeat and Figure 12 is a diagrammatic view of a row of teeth.

Referring to Figures '1 and 4, the cone I ll is here shown as sharply pointed at about with a collar or threaded base portion 9 to fit the X-ray machine having a tube for sending rays toward the point of the cone in order to radiograph human teeth or other parts under observation.

The improvement now consists in providing two or more side vanes or radial wings at the small end or point of the cone. In thi figure two wings are shown very thin and directed dia: metrically opposite to each other with the front edge I?! running perpendicularly to the axis of the cone In or parallel to the base or collar 9. edge may be formed as a ridge [3 or to consist of a narrow groove along its middle line which may be colored, to be used in the same manner as a bead on a rifle sight. In Figure 2, the wings I I are shown as integral parts of the hollow cone body and of triangular shape so that its straight side edge l4 meets the side of the cone at an acute angle. This is however, of no importance, as the edge, instead of being straight, may follow a concave or convex curve. What is important, however, is that the edge 12 is straight and runs at right angles to the axis of the cone In.

The modification shown in Figures 6 and 7 differs only slightly from that just described. The two side wings IS, in this case having their beaded front edges 11 inclined backward from the point of the cone about 60 against the cone axis.

In Figures 8 and 9 is shown a blunt nosed cone 20 secured as before by a threaded collar portion 1 9 to the X-ray machine. Its flat nose 2:! parallel with face of collar I9, is perpendicular to the cone axis and to the edges 22 of the four side win s 23 and run level with the front surface of the nose 2|. These wings are arranged in pairs at right. angles to each other and may as befor be provided with a straight line head or a colored groove 24, which, in the latter case continues unbroken across the nose 2|.

When the machine is used in the profession of dentistry for taking a radiograph of a row of posterior teeth, as in Figure 12, the dentist places the X-ray machine in such a position that the ridge or bead line it is accurately parallel to the center line 2E25 of the teeth 21, Figure 12, and close enough to obtain a perfect radiograph of the condition of the teeth. In this case, the two winged cone I0 shown in Figures 2 and 3, should be used or the four winged cone of Figures and 11 may be employed. The side faces of the wings are then held vertical to the floor level and act as a bead, bisecting the areas to be radiographed. This will prevent the overlapping of images on the X-ray film.

In the case of the four winged cone, one pair of wings is alined in the plane of tooth line 26-46, while the other pair of wings is placed at right angles thereto.

In general, when X-rays are to be taken of organs of human beings or animals, then the ridge or groove l3 or 24 is placed parallel to the organ which is to be radiographed.

The device has a great advantage in taking very accurate and detailed radiographs, because of the easier positioning of this machine when tube-target distance is increased from the normal distance. Even when the machine is tilted it can still be positioned properly. Most efficient is this device when the target distance is increased from the normal 8 inches to the maximum 20 inches. It is to be understood that the invention as herein disclosed may be varied from the details described and shown without departure from the spirit of the subjoined claims.

I claim:

1. A cone for X-ray machines having indicator elements projecting from opposite sides of the same, said elements each having a like straight edge terminating at the apex of the cone for the sight aiming of the apex on a target.

2. The invention as defined in claim 1, with the said straight edges having means extending along the same to facilitate the sight aiming procedure.

3. The invention as defined in claim 1, with the said indicator elements constituted in flat relatively thin wing-like members and triangular in form.

4. The invention as defined in claim 1, with the said indicator elements made integral with and of the same material as that of the cone.

5. The invention as defined in claim 1, with the said indicator elements constituted in pairs and one pair of the same is disposed in rightangular relation with respect to the other pair.

6. The invention as defined in claim 1, with the said straight edges disposed in alignment and extending perpendicularly to the axis of the cone.
