DENTAL CHAIR ATTACHMENT Filed Dec. 50, 1930 INVENTOR.

James 51 Miller ATTORNEY.

Patented Aug. 9, 1932 UNITED STATES JAMES S. MILLER, OF TRENTON, NEW JERSEY DENTAL CHAIR ATTACHMENT Application filed December 30, 1930. Serial No. 505,592.

This invention relates to dental chairs and more particularly to the means of covering and attaching a paper towel to the head-rests of the chairs.

The principal object of the invention is to provide a means of securely holding a paper towel around a head-rest of a dental chair without slippage and without being torn.

LIL) Another object of the invention is to provide a towel which will conform tothe shape of the head-rest and which can easily be attached and removed therefrom.

Other objects of the invention will appear as the disclosure progresses. The drawing is intended to merely indicate a possible embodiment of the invention. It is obvious that the actual practice of the invention will necessitate certain mechanical changes. It is therefore not intended to limit the invention to the embodiment but rather to define such limits in the appended claim. For a more general understanding of the invention attention is called to the drawing. In the drawing like reference characters denote like parts throughout the specification.

In the drawing:

Figure 1 is a top view of a head rest of a dental chair showing the towel covering same and the means to hold the towel in place.

Figure 2 is a section on line 22 of Fig ure 1.

Referring now to the drawing in detail, numeral 1 designates the head-rest of a clental chair including the usual head pads 2, the

' brace 3 for holding the head pads and the fork 4 for supporting the brace. Covering the head-rest is a paper towel 5. The towel is made from crinkled paper so it can stretch and conform to the shape of the head of the patient without being torn.

Referring now to Figures 1 and 2, numeral 7 designates the clip for holding the edges of the towel as it is wrapped around the headrest. The clip comprises a U-shaped member 8 fastened to the brace 3 by a set screw 9. At-

tached to the U-shaped member by a rivet 10 is a spring gripping member 11 having a set of knobs 12 at the ends. As shown in Figure 2 the ends 13 of the towel are resiliently gripped between the legs 14 of the U-shaped member 8 and the legs 15 0f the spring gripping member. By pulling on the knobs 12 against the normal .resiliency of the spring member 11 the edges of the towel can be released when it becomes necessary to replace the towels.

It will thus be seen that I have provided a simple .and efficient method of holding a paper'towel around the head rest of a dental chair. The towel is .made from crinkled paper so it will give? and conform to the shape of the patients head. The corners are cut at a bevel so the towel can easily and readily be applied in place. The clips will resiliently hold the towel againstslippage without being torn and damaged.

Having described my invention, I claim,

In a clip of the class described, the combination of a U-shaped rigid member, of a U- shaped resilient member, and means for fastening both of said members together while leaving the legs of both of said members being free so that the legs of the said resilient member can move away from the legs of the said rigid member, a knob attached to'each of the legs of said resilient member, and corrugations in said resilient member near the fastening means.

In testimony whereof, I aiiix my signature.

JAMES S. MILLER.
