DENTAL FLEXIBLE SUPPORT. No. 354,976. Patented Dec. 28, 1886,

lhsrrnn STATES ATENT Fries.

GEORGE L. FIELD, OF DETROIT, MICHIGAN.

'DENTAL FLEXIBLE SUPPORT.

ELJI EICA'IIEION' forming part of Letters Patent No. 354,976, dated December 28, 1886.

Application filed April 29, 1886. SerialNo. 200,561. (No model.)

on dental chairs, though it may be applied to a variety of other uses.

Figure l is an elevation of the complete device attached to a chair. Figs. 2 and 3 are elevations of one of the sections of the support.

G represents a chair, to any suitable part of which is attached a sleeve, 71, carrying a setscrew, h. I usually attach the sleeve to the back upright of the chair on the side opposite that where the operator is accustomed to stand while at work; but its point of attachment may be varied at will.

F represents a rod, which may be either straight or bent in any desired form, as shown in thev drawings, one end of which slides in the sleeveh, and is secured in any desired po-' sition therein by the set-screw h.

E represents the lower section of the flexible support, consisting of a sleeve adapted to slide over the upper end of rod F and the setscrew G to secure said sleeve in position, and carrying at its upperend two jaws, d, which are permitted to spring slightly by means of a slot, 3, and can be forced toward-each other by means of a screw, e, which passes loosely through one jaw and is tapped into the other.

D D represent sections all alike, which to: gether form my flexible support. Each section consists of a shank, D, a ball, (1, at one end of the shank, and a pair of jaws, d, at the other end of the shank provided with asl'ot, s, and screw '6, as hereinbefore described.

Near the end of thejaw a hole,f, is drilled, through said jaws, as shown in Figs. 2 and3, and I prefer to have said holes straight and not countersunk on the inner side of the jaw, because this gives more play to the next section, though said holes may be countersunk. The jaws d of the section E are also provided .with similar holes, f.

A represents a lens set in a metal frame, B, which is secured by a screw, 0, orin any convenient manner to a shank similar to B, having on its end a ball similar to d.

The support is put together by loosening screw 6 of the section E until the ball d of one of the sections D can be forced between said jaws d until it rests in the hole f, when the jaws d are compressed upon said ball by tightening the screw 6,- and it is evident that the amount of friction between the jaws herewith and the ball cl can be regulated by the screw 6 to make the support pliable or stiff. One or more sections D may be added in the same manner untilthe support is the desired length, and the lens A put onto the end of the support in the same way.

- It is obvious that, instead of a lens, any other article may be carried by the support; and I have shown a lens attached to the support, because myinvention is designed chiefly to enable a dentist to use the lens in working upon teeth and yet have both hands free.

\Vith this support the lens may be adjusted readily and quickly in front of the patients mouth, no matter in what position that may be.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is

l. A section for a flexible support, consisting of the shank D, provided at one end with the sphere d and at the other end with the two jaws d d, for receiving between them a ball, and acompression set-screw, e, for clamping thejaws upon the ball between them, substantiall y as described:

, 2. The combination, with the sleeve E, adapted to be connected with a dental chair and having two compressible jaws, d d, and compression-screw e, of the flexible support,

comprising a series of connected shanks, D,
