COMPLETE SPECIFICATION.
Teeth Regulator.
I, Dr. DEEL RINALDO WILDER, of Los Angeles City, in the County of Los
Angeles and State of California United States of America, Dentist, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
One object of my invention is to provide more convenient and more secure and
stable means for attaching the regulator to the teeth, whereby the same can with
ease be attached to and removed from the teeth and can be used repeatedly and on
different patients, and whereby the regulator is so firmly supported when in place
that it will not displace the teeth to which it is attached.
A further object of my invention is to afford means whereby the tooth can be
drawn closer to the regulator-bar than it is possible with the devices of this class
now in use.
The accompanying drawings illustrate my invention.
Figure 1 is a side perspective view of my invention in position for use as it
appears when secured to the teeth. The upper and lower sets of teeth are both
indicated in this view; but it is to be understood that the attachment to the lower
set, as shown in this figure, or to the upper set, as the case may be, can be omitted
in cases where the strain will not be great enough to displace the anchor-teeth of
one set alone. It is to be understood that the other end of the bar is provided
with fastening devices which are the duplicates of those shown in this figure. This
is indicated in Fig. 2. The several anchor-blocks are reversed in position when
placed on the opposite sides of the jaw; but such blocks are the same at top and
bottom and can be used interchangeably upon both sides of the mouth by simply
turning them over.
Fig. 2 is a plan view of my improved regulator in position attached to a set of
teeth, which are shown in horizontal transverse section.
Fig. 3 is a view of the outside of the anchor-block.
Fig. 4 is a vertical longitudinal mid-section of the joint which connects the upper
and lower anchor-blocks. The shanks G G' are shown intact at their corrugated
portions.
Fig. 5 is a view similar to Fig. 4, showing a joint arranged to allow greater
movement of the jaws than the form shown in Fig. 4.
Fig. 6 is a perspective view of the sliding pintle and its clamp-shank.
Fig. 7 is a side view of the rack-bar by which the regulator-bar is adjustably
attached to the clamp-block.
Fig. 8 is a plan elevation of the clamp-screw and its cross-head for securing
the rack-bars and shanks in place.
Fig. 9 is a plan of such cross-head.
Fig. 10 shows the several parts of the ball-and-socket joint in detail.
With relation to the regulator-bar-attaching device my invention consists,

page_text: essentially, of the combination of an anchor-block A, a clamp-hand B, secured at
one end to such block and adapted to partially encircle the anchor-tooth, a band-
tightening jack arranged in connection with the anchor-block to draw the tooth-
band tight to clamp the anchor-tooth, and means for securing the regulator-bar to
the anchor-block. The clamp-band is preferably secured by a screw d to the
anchor-block through the medium of a lug e, projecting from such block. The
band-tightening jack consists of the combination of the anchor-block to which
the band is secured by one end, a cramp-block operating jack-screw c, arranged to
screw through a suitable lug a, projecting from the inner face of such block, and a
movable cramp-block b, mounted upon the jack-screw and arranged with sufficient
space between it and the anchor-block to chamber the end of the clamp-band,
which is bent at an angle with the main body of the band in order to be inserted
in such space and fitted therein, as shown that is to say, the end of the band is
bent outward from the curve of its main body, so that when the band is in place
about the tooth and is passed between the tooth and the movable block the bent
end can be made to enter the space between the movable cramp-block and the
anchor-block, and will thereby be so connected with the cramp-block that when
the block is advanced by the screw it will operate to tighten the band upon the
tooth. The cramp-block & is pointed at f to fit into the angular bend of the band.
By this means it is made possible to easily fasten the clamp-band to the tightening-
jack after the appliance has been placed in the mouth.
The anchor-blocks A are channeled in their outer faces to seat the corrugated
shanks of the joint, and also the rack-bar D, to which the regulator-bar E is
attached. In the drawings the screw i suggests the means for attachment. The
bottom of the channel F in the anchor-block is corrugated to seat the corrugations
of the shanks of the joint and prevent slipping. The channel is of sufficient depth
to seat both the rack-bar D and the corrugated portion of the shank G G¹ of the
joint. Such shanks are provided with two corrugated sides a g', so that contact
with the bottom of the channel will prevent the shank from slipping and contact
with the corrugated face of the rack-bar will prevent such bar from slipping when
the parts are clamped together, as shown.
The means for clamping the shank and rack-bar in the channel consists of a
clamp-screw H and a suitable cross-head I, through which the clamp-screw H
screws to engage the rack-bar. The cross-head is secured to the side walls J J of
the anchor-block, which form the channel F, by suitable means, such as the cross-head-
retaining hooks or lugs j j, under which the cross-head is placed when the several
other parts are in position, as shown in Figs. 1 and 2, and as hereinafter described.
A curved spring-plate K is fixed to the inner face of the clamp-block to fit upon
the outer face of the tooth and sustain the pressure of the tooth-band.
The teeth-regulator bar E is formed of two side rails 1 and a series of cross-
bars m, extending across between the side rails like the rungs of a ladder to form
attachments for the cords or bands no, which are used in drawing the teeth into
proper position.
In regulating teeth it is frequently found that the strain upon the regulator-bar
is so great that the anchor-teeth-i.e., the teeth to which the bar is secured to
retain it in place-yield under the pressure and become forced out of place. I
provide against this by the means indicated in Fig. 1, which means comprise the
combination of upper and lower anchoring devices comprising the anchor-
blocks A A' and suitable means for securing such anchor-blocks, respectively, to
anchor-teeth Pg of the upper and lower jaws, two suitable hinge-shanks adapted to
be secured, respectively, to the upper and lower anchor-blocks, and a combined
ball-and-socket and extensible joint arranged to connect such shanks.
bined ball-and-socket and extensible joint consists of the combination of a telescoping
tube R, provided at one end with the ball r, a semi-spherical socket S, fixed to one
of the shanks and adapted to seat such ball, a perforated screw-cap T, arranged to
encircle the tube screwed upon such socket and adapted to retain the ball therein
and allow free movement of the ball within the socket, and a telescoping pintle U,
The com-

page_text: fixed to the other shank and arranged to slide in the telescoping tube. I prefer
to split the pintle at its free end, as shown in Fig. 6, so that the two limbs un
may be spread apart slightly and given sufficient spring to cause them to fit snugly
in the tube, so that the pintle will not move with too great freedom.
In practice, when it is desired to attach the device to the teeth the jack is set
with the movable block retracted toward lug a, and the tooth-band B is secured
to the lug e by screw d. Then the band is placed in position about the tooth and
its bent portion is inserted into the space between the movable block b and the
main body of the anchor-block, and the screw c is then turned to force the movable
block toward the tooth into the position shown in Fig. 2 to draw the band tight
upon the tooth. Each anchor-block is set in place in this way, and then the shank G
of the joint
or hinge is placed in the channel F of the anchor-block, the rack-bar D
is set in position on the shank in the channel, the cross-head I is set in position
beneath the hooks j, and the clamp-screw H is screwed to press against the rack-
bar and clamp it and the shank firmly in place. The bottom of the channel is
corrugated, as indicated in Fig. 3, and the shank is corrugated on two sides to fit
thereon and to form a corrugated seat for the rack-bar, so that when the clamp-
screw is screwed into place the shank and clamp-bar are both firmly secured.
When the double anchorage is employed-that is, when attachment is made to
both the upper and lower teeth-the several anchor-blocks are first set in position
and one of the shanks is clamped to its anchor-block, and then after adjusting
the parts of the joint into the position desired the other shank is clamped to its
block.
The extensible ball-and-socket joint shown allows the patient to move the lower
jaw with perfect freedom; but the connection between the upper and lower anchor-
blocks is such that both blocks mutually bear the strain exerted by the regulator-
bar when the teeth are being regulated.
When the several anchor-blocks are clamped in place, the regulator-bar is
adjusted in proper position with relation to the teeth and the rack-bars D are
placed in the channels with their corrugated faces in engagement, respectively,
with the outer corrugated faces of the shanks, the cross-heads are inserted beneath
the hooks or lugs j, and the clamp-screws are screwed firmly against the rack-bars,
thus clamping them and the shanks in place in the channels. When the regulator-
bar is finally adjusted and firmly clamped in place, the rubber bands o are applied
in the ordinary manner to the teeth to be regulated, and the cords », by which they
are to be drawn toward the regulator-bar, are drawn over the rungs m and secured
thereto. The bands can be stretched to any extent desired, even when stretched
so as to pass between the rungs, for the end of the cord n can be carried to another
rung and the rubber band drawn over the rung so far as may be necessary, so that
the tooth can be drawn snug against the regulator-bar, if desired.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what
claim is;-
1. In a teeth-regulator, the combination set forth of an anchor-block, a clamp-
band adapted to only partially encircle the anchor-tooth, and having one end
attached to such anchor-block and having its other end adapted to be attached to
