SANITARY DENTAL WASTERECEPTACLE.

Specification of Letters Patent. Application filed June 19, 1909. Serial no. 503,079.

Patented Apr. 2, 1912.

I To all whom 'it may concern:

Be it: known that I, THoMAs S. HARLAN, a citizen of the United States of America, and resident of Salt Lake City, Salt Lake county,

Utah, have invented a certain new and usethe said cup holder being provided with a swiveled support adapted to be fastened to the under side of acabinet or table, whereby the receptacle .can be swung out of sight beneath the cabinet or table, as will heremafter more fully appear.

In the accompanying drawings-Figure 1 is a perspective of a sanitary dental waste receptacle, embodying "the principles of my invention, showing the same attached to the under side of the corner of adental cabinet. Fig. 2 is an enlarged plan view of the receptacle shown in Fi 1. Fig. 3 is a vertical 'volve about a vertical axis.

sectional view on line 3--3 in Fig. 2.

Asthus illustrated, my invention com.- prises an L-shaped arm A provided at its upper end with a reduced end portion a and at its lower and right hand end with an upstanding threaded portion a'. A bracket bearing B is provided with holes 6, whereby the same can'be attached to the under side of the cabinet X, said bracket bearing being also provided with a vertical bore or openingb adapted to receive the stem a of the arm. The top of the bracket bearing B has a depression or seat b, in which is disposed a washer b the upper end of the stem a being riveted over tohold the said washer thereon. Inthis W l y a swivel connection is pz-ovided between the arm A and the bracket aring 13, whereby the arm is adapted to re- The cup C is provided with annular side walls. and with a head or rib 0 extending circumferentially' thereof, located some distance above the bottom thereof. An annular cup-holder D is also provided, the perimeter d thereof being rounded and curled over to provideedges (2' that engage immediately below the bead or rib c, as shown. Thus the cup is supported by contact therewith at some distance above its bottom or lower edge, and does not contact with the bottom ofthe cup-holder. The said cup-holder is provided with a centrally disposed and downwardly projecting boss d provided with a threaded bore or opening adapted to receive the threaded stud a on the swinging or swiveled arm. In this way the cup is removable from the cup-holder, and the cup-holder is removable from the L-shaped swiveled arm by which it is carried. As a matter of further and special improvement, the said cup may have a portion of the interior thereof provided with a series of teeth E, disposed near the perimeter or upper edge of the cup, whereby cotton or waste may be readily dislodged from the dental instrument. By placing the instrument between two of the teeth, and then drawing the instrument upward, the cotton or waste or other material on the lower end of the instrument will be completely dislodged or removed therefrom.

From the foregoing, it will be seen that the advantages of my invention are as follows: It is sanitary, because it can be emptied and sterilized after each patient, or at any time, without consuming more than a moments time. of sight of the patient at all times. and the swinging arm enables the operator to swing the cup under the corner of the table, so that the next patient taking the chair cannot see into the cup; then when the patient The contents are out is seated, and the operator pulls the table up to the patient. the cup may be pulled cup without the patient having seen the contents thereof. It holds any and all waste from the dental table. The receptacle proper, being cup-shaped, holds any and all waste, such as old burs, disks, polishing strips, ligatures, carborundum, stones, articulating paper, all sized cotton pellets and the cotton "rolls which are being used more every day, and any size that is used in the mouth can be put in this receptacle, and much other waste from the dental chair. The re.- ceptacle, being fastened to the nearest right hand corner of the table, enables the operator to dispose of waste with, the least loss of time; and should heavy oils or coagulations of blood cause cotton to hang to, the pliers, the operator can do this by drawing the pliers to the right until the cotton comes in contact with a set of spurs or teeth fastened near the top and on the inside with points curved downward where it' space 'onthe table. The receptacle, being. placed underneath the table, is out of the Way, and occupies space that can be used for nothing else, leaving the table for instruments or. other things necessary for the work. L

The receptacle, being made of steel or copper, heavily nickeled and nicely orna mented, is quite an ornament to any dental table. Being made of heavy steel or copper, and being heavily nickeled, the. device should last a lifetime,' and the cup cannot 'be knocked out of its position unless taken hold of and lifted straight up.' The shank of the receptacle is fastened to the frame of the table by two screws which securely fasten it, and the receptacle proper can be turned around easily without jarring the table or loosening anything, as it fits in a socket. The sides of the cup-holder bulge outwardly beyond the cup, thus guarding the latter against contact with other objects' that might cause its dislodgment, or'

tends to do so.

Although I have described my invention as being particularly useful in connection with dental work, it will be understood that I do not so limit myself, and that it may be used for various purposes without in any way departing from the spiritoi my invention.

What I claim as my invention is: 1. A sanitary dental waste receptacle comprising an 'L-shaped arm provided with a swivel at its upper end, an annular cupholder disposed upon the lower end of said lower end of the arm, and a cup removably.

disposed in said cup-holder, the latter being formed with an annular perimeter, and with sides bulging outwardly beyond the perim- .eter of the said cup.

3. In a device of the character disclosed,

an L-shaped arm, a swivel for the, upper endof said arm, adapted to be attached to the under side of a support, a cup-holder for the lower end of sai arm, and a cup removably disposed in said cup-holder, said cup provided with an annular bead or rib located at a distance above the bottom thereof, and the said cup-holder being provided with an annular and inwardly projecting edge or perimeter adapted to engage the cup im mediately below-said bead or rib, ,as set forth.

Signed by this 14th day of June, 1909.
