DAVID N. BOOTH, OF NEIV YORK, N. Y.
APPARATUS FOR SHAPING METAL PARTS IN DENTAL WORK.
SPECIFICATION forming part of Letters Patent No. 766,586, dated August 2, 1904.
Application filed February 5,1904. Serial No. 192,097. (No model.)
To (all whom it may concern.-
Be it known that I, DAVID N. BOOTH, a citizen of the United States, residing in the borough of Manhattan, in the city, county, and State of New York, have invented an Improvement in Apparatus for Shaping Metal Parts in Dental W'ork, of which the following is a specification.
My invention relates to apparatus for shaping metal parts in dental work, and particularly to apparatus for shaping the metal gibs employed for various classes of artificial teeth and the grooved metal backings into which the same are fitted and secured.
In carrying out my invention I employ a double frame, means for clamping both parts of the frame together, slidably-adjustable members having correspondingly-beveled sides arranged in both parts of said frame, and means for clamping and holding said adjustable members in any desired positions within the said frame parts, all of which, together with the use of the apparatus, will be hereinafter more fully described.
In the drawings, Figure 1 is plan of the under frame and the parts connected therewith. Fig. 2 is a cross-section on the line .r n' of Fig. 1; and Fig. 3 is a cross-section on the line 3/ y, Fig. 1. Fig. A is a plan of the frame parts combined. Fig. 5 is a cross-section on the line .2 .2, Fig. A. Fig. 6 is a side elevation of Fig. 1. Figs. 7 and 9 are rear elevations of artificial teeth, and Fig. 8 is a side elevation of the tooth represented in Fig. 7. Fig. 10 is a rear elevation of an artificial tooth, showing the gib attached thereto; and Fig. 11 is a cross-section of the same. Fig. 12 is a view similar to Fig. 11, showing the tooth and its gib secured in the backing. Fig. 13 is a section of the position which the adjustable members of the apparatus are made to assume in the first step in the shaping of the gib. Fig. 14 shows the same parts with the gib cut from the metal from which the same is made. Fig. 15 is a section of these parts, showing the first step in forming the backing; and Fig. 16 is a similar view, showing the backing bent into shape.
As hereinbefore stated, my invention comprises a double or two-part frame, the under member of which is composed of sides a and ends 7), connected in any suitable manner and preferably rectangular in outline.
2, 3, A, 5, and 6 represent slidably-adjustable members whose ends are recessed so as to fit and be received in the beveled portion of the sides a, so that the ends of the adjustable members extend over the upper surface of the sides a. The adjustable members 3 and 4. have oppositely-inclined sides and the adjustable members 2 and 5 are so shaped that the sides adjacent to the members 3 and 4, respectively, are parallel to the inclined sides of the said members 3 and 4. The adjustable member 6 is preferably integral, having its sides oppositely inclined. This member together with the members 3 and 4: are provided with vertical apertures 0, arranged in pairs. The adjustable members 3 and 4 are provided at their extremities with brackets 7 and 8, respectively, and adjusting-screws c are pivotally connected in the brackets 7 and adapted to pass through and engage the brackets 8, so that the said members 3 and 4 may be brought together or moved apart and the relation between the same adjusted to any desired position.
9, 10, and 11 represent blocks which are placed between the ends of the adjustable members 2 3, 4: 5, and 2 6 to maintain these parts in a given relation in which the same may have been placed, and 12 represents a block which is placed between the adjustable member 5 and one end of the frame 7).
(Z is a clamp-screw passing through the opposite end of the frame and adapted to bear against the adjustable member 6 in order to clamp all the parts within the frame in a desired fixed relation, and the end members 6 of the frame are provided with uprights or posts 13, the ends of which are provided with screwthreads and which function will be hereinafter set forth.
The upper member of the frame is similar in construction to the lower member a 6, representing, respectively, the sides and ends of the same, and 14 15, 16 17, 18 slidably-adjustable members corresponding to similar members 2 3, 1- 5, and 6 in the lower frame, the members 15 16 and 18 being provided with apertures in similar positions to corresponding apertures e in the similar members in the lower frame. A block 19 is .employed in connection with the upper frame similar to the block 12 hereinbefore referred to, and the blocks which are employed between the adjustable members 14, 15, 16,'and 17 and 14: 18 are represented at 20, 21, and 22. The members 16 are also provided with brackets 23 and 2 1 and adjustings'crews 0', corresponding, respectively, with the brackets 7 8 and adjusting-screws cof the under part of the frame. The ends of the upper frame part are provided wi th holes through which when the upper frame part is superimposed upon the lower the posts 13 pass, and I also employ nuts 25, adapted to fit the post 13, by which means the said frame parts may be securely fastened together. The sides and ends of both parts of the frame may be connected in any suitable manner, but are preferably connected by means of pins 26, so that the frames may be readily taken apart in order to interchange the adjustable members 3 4 for the member 6, or vice versa, and the members 15 16 for the member 18.
-Referring to Figs. 7, 8, and 9, artificial teeth f are manufactured with pins 27, which are secured in the teeth and extend appreciably beyond the rear surface of the same. These pins, as shown, may be placed either ina horizontal or a vertical line. To these pins 27 the dovetailed gib h is secured, as shown in Figs. 10 and 11, and by means of the gib it the tooth is secured in the grooved backing d, as shown in Fig. 12: The object of the apparatus, as hereinbefore described, is to so shape the gib and the backing for any particular tooth that the one will fit the other perfectly.
The apparatus is used as follows, presuming a gib and backing are to be shaped for any given tooth: The tooth is placed upon the adjustable members 3 and 4 of the under frame and the said members adjusted so that the pins 27 fit within a pair of openings 6, after which the tooth is removed-and the adjustable members 2 and 5 set in position with the desired space between the same and the members3 4, and the parts are then ready to be clamped within the frame by the screw cl. The upper frame member is now superimposed upon the under, and the adjustable members 15 16 are placed above the members 3 4c and adjusted to such a position that the apertures e therein correspond with the apertures e in the members 3 4:, after which the members 14 17 are placed in a position corresponding to the members 2 5, respectively, in the under frame, whereupon the members in the upper frame are rigidly fixed in position by the clamp-screw b. The strip of metal h or other material from which the gib is to be shaped is now placed longitudinally of the apparatus and centrally of the apertures in which the pins of the tooth were fitted and the upper frame member clamped to the lower member by the nuts 25. Holes to receive the pins of the tooth are now made in the metal h by a suitable punch or drill or in any other desired manner, and by employinga punch or a saw and passing the point of the tool between the members 1 1 15 and 16 17 a portion of the metal it may be cut away to form the gib h, as shown in Figs. 13 and '14:. As illustrated in Figs. 15 and 16, the metal d, from which the backing is to be shaped, may now be placed between the adjustable members and the frame parts and above the gib h and by a suitable tool bent down to position, as shown in Fig. 16, so thatthe groove formed in the backing is made directly over the gib which it is to receive and necessarily makes a perfect fit between these parts.
It will be readily apparent that when the pins 27 are arranged in a line longitudinally of the tooth, as shown in Fig. 9, it will be necessary to substitute the adjustable members 1. In an apparatus for shaping metal parts in dental work, the combination with a double frame, of slidably-adjustable and corresponding members having inclined sides in the said double frame, means for maintaining said members in any desired positions within the frame parts, means for clamping said members in the said positions, and means for securing the said frame parts together.
2. In an apparatus for shaping metal parts in dental work, the combination with the twopart frame, of slidably-adjustable and corresponding members having inclined sides and arranged in both parts of said frame, means for maintaining said members in any desired position within the frame parts, means for clamping said members in the said positions, and means for securing the said frame parts together.
3. In an apparatus for shaping metal parts in dental work, the combination with a twopart frame, of slidablyadjustable and corresponding members having inclined sides arranged in both parts of said frame, there being apertures in pairs in one or more of said adjustable members, means for maintaining the said adjustable members in any desired positions within the frame parts, means for clamping said members in said positions, and means for securing said frame parts together.
4. In an apparatus for shaping metal parts in dental work, the combination with a two part frame, of two slidably-adjustable members having oppositely-inclined sides and ap-- ertures in pairs therein arranged in both parts of said frame, means for adjusting the relative positions of said members, other slidablyadjustable members arranged in both parts of said frame on either side of the aforesaid members and having faces inclined and respectively parallel to the adjacent faces of the said aforesaid members.
5. In an apparatus for shaping metal parts in dental work, the combination with a twopart frame, of two slidably-adjustable members 11a ing oppositely-inclined sides and apertures in pairs therein arranged in both parts of said frame, means for adjusting the relative positions of said members, other slidablyadj ustablc members arranged in both parts of said frame on either side of the aforesaid members and having faces inclined and respectively parallel to the adjacent faces of the said aforesaid members, blocks for maintaining the said members in any desired position within the frame parts, means for clamping said members in said position, and means for securing said frame parts together.
6. In an apparatus for shaping metal parts in dental work, the combination with a twoa part frame, of two slidably-adjustable members having oppositely-inclined sides and apertures in pairs therein arranged in both parts of said frame, means for adjusting the relative positions of said members, other slidablyadjustable members arranged in both parts of said frame on either side of the aforesaid members and having faces inclined and respectively parallel to the adjacent faces of the said aforesaid members, blocks for maintaining the said members in any desired position within the frame parts, a screw in each of said frame parts for clamping the adjustable members therein in a given position, and means for securing said frame parts together.
