I To all whom it may concern:.

Be it known that I, GEORGE HALL, a citi-.

zen pfthe United States, residing at Lima, in the county of Allen'and State of Ohio, have 5"invented certain new and useful Improvements in Combination Dental Brackets, of which the following is a specification.

This invention relates to improvements in coinbination dental brackets and has feiloyits object to provide an appliance, adapted for use in certain professions, such as dentistry, which will be conveniently located upona support, as for instance a window frame, orpart of a room wall, and which may The device simple. and efficient in its manipulation, and

provides a convenient accessory for those aged in the above named profession. I

he invention embodies a wall bracket'of usual. construction provided with pivoted extensions, which are adjustable to a variety of positions, and these extensions are adapted to support the appliances required in-the. 2!; practice of the work of dentistry, such as a swinging. table, water heater, motor, fan, lightattachment, and machine for operating 'theinstrumentsin practice. 4

A s stem of electric wiring is provided throng out the device forfnrnishing power to the operating parts, heat to the water heater, andlight to thedamp attachment.

The invention further consists in certain novel features of construction and combinations andarrangements of parts as hereinafter described,- more particularly pointed out in the clain1s, and as illustrated in the accox'nlpanying drawings. T 1e accompanyingdrawlngs lllustrateone 4c example of the physicalembodiment of the" invention, constructed according to the best mode I.l1ave so fardevised for its practical application.

Referring to the drawings: Figure l is a perspective view of the complete invention,

shown as supported fronna suitable position. Fig. 2 :is a sldc elevation of the operating parts of the bracket. Fig. 3 is a' broken detail view,enlarged, as seen from the rear side of F ig'. 2, showingthe adjustable connecting means of the arts comprising the bracket. Fig. 4 is a sectional view of extreme outer ortensionof the bracket, or the motor Supporting:arm, showing theprovision for carrying theconcealed electric wires.

The base or support A of the bracket is secured by suitable means, such as screws, at the proper height, upon a solid support and this base piece is provided with-lugsB, l3, in which the vertical member 0 is pivoted, thus providing a laterally swinging movement of the member C, and also the entire apparatus supported thereon. The swinging member C is provided with two bolts 1, 2, whichsupport the frame arms 3 3. These arms are formed at their outer ends with a box 4, which box forms the pivotal support for the bracket arms 5, 5, which are formed at their converging ends with sin-integral head 6, the bracket arms being pivoted thereto at 7, 7" respectively.

As seen more clearly inFig.3, the frame bar 3 pivotally connected to the frame or bracket 55 provided with a'ratchet head 8 to'which the bracket arm 5 is adjustably held by the pawl 9, which is held to position by a spring 10, said pawl being fast on the .axle of the wheel 1] provided for conveniently turnin the pawl out of engagement with the ratchet when it is desired to adjust the height of the bracket arms 5 and- 5, thus providing for a vertical adjustment of the said arms. A head 12, is formed preferably integral with the arm 5 and ivotally supports, through the medium oft e seated head 12,-an arm 13 on which arm 13, the table 14 is in turn pivotally sup orted, as usual. An electric light 16, may esii ported on the boxing 4, on the rod 15, if so esired, and this light may be provided with the usual reflector 16.

such articles as necessary.' 1

- As seen more clearly in Fig. 4,.the extension arm 18.is formed with side flanges 18 providing an open construction, for a pur- -'pose to be described, and said arm is formed with a depending lug or pintle 19., adapted to 'be seated in asocket 20 of the headb Wherein it is free to turn. A recessed head 21 is Thctable may also serve -as a support for the water heater 17 and any other formedat the extreme end of-the'extension form a ball bearing connection between head 21 and the base 23 of an electric motor 24. As shown in El 1, this motor may be used 18 and is adapted to receive the balls 22 to for running a .an or serve the function of' driving the dental engine. I do not claim this motor and its driving connections as part of my invention, so it need not be further described here,

through the opening 46 in the head 6, u into and through the conduit 47 formed in t 1eextension arm 18, through the aperture 48 of the head 21 and so to the motor. cross pins 49 may be introduced through the conduit 47 to support the wire if desired.

The lighting wire is carried from the box 4 through the hollow standard 15 and out at its upper end, and from thence connected with the light appliance. The heating wire is connected by an attachment 50 to the box 4 and receives current from the wires within the flexible tube 44.

It will be observed from the above description taken with the drawings that the bracket arms 5 5 are vertically adjustable; the motor carrying extension 18 is movable in a hori zontal plane to the desired position for operation; the pulley head is provided with a spring support which insures a uniform and regular connection by cable between the wheels 36 and 3&4 and obviates vibration between the parts of the machine.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 7 1. A dental bracket comprising a base, a vertical hollow frame member pivoted there to capable of-lateral swinging movement, horizontal parallel frame arms having their ends engaged in the hollow vertical member and bolts passing through said vertical memher to secure the arms therein, the outer ends of the frame arms terminating in a hollow Rods or,

box, bracket arms pivoted in said hollow box, the converging ends of the bracket arms terminating in supporting head, the'lowermost parallel frame bar provided at its outer end with a ratchet head, a wheel pivoted in the lowermost bracket arm, a pawl on the axle of said wheel to engage the ratchet head,

and a spring to hold the pawl in properengagement therewith.

2. A dental bracket comprising a base, a vertical frame member pivoted thereto, horizontal frame arms having their ends engaged in the vertical member, the outer ends of the frame arms terminating in a hollow box, bracket arms pivoted in said hollow box, the converging ends of the bracket arms terminating in a supporting head, and pawl and ratchet mechanism on the irame bars and bracket arms to hold the members in adjustable relation.

3. A dental bracket comprising a base, a vertical frame member pivoted thereto, horizontal frame arms having their ends engaged in the Vertical member, the outer ends of the frame arms terminating in a hollow box, bracket arms pivoted in said hollow box, the converging ends of the bracket arms terminating in a supporting head and a motor sup port arranged on said head, pawl and ratchet mechanism on the frame bars and bracket arms to hold the members in adjustable relation, and a table pivotally mounted upon the bracket arms.

In testimony \rbereol l aflix my signature in presence of two witnesses.
