SANITARY DENTAL TRAY.
Specification of Letters Patent.
Patented N ov. 3, 1914.
Application led January 20, 1914. Serial No. 813,225.
To all whom it may concern:
Be it known that IMNATHANIEL A. MAsER, a citizen of the United States, residing at Vineland, in the county of Cumberland and State of New Jersey, have invented new and useful Improvements in Sanitary Dental Trays, of which the following is a specification.
My invention relates to new and useful improvements in sanitary dental trays, and has for its object to produce a device of this character from glass or other sanitary material which may be used for holding a number of different medicines, and other objects of the dental profession which when not in use will be sealed to prevent contamination and deterioration or evaporation of the medicines, and to also temporarily hold certain instruments to keep them in a practically sterile condition.
Another object of the invention is to pro vide a single tray having a number of compartments adapted to hold all the necessary articles for treating a tooth which may be placed upon the ordinary bracket table Within easy reach of the doctor, thereby eliminating unnecessary steps and the necessity of looking for medicines in the medicine cabinet.
A further object of the invention is to provide a device of this character whereby the necessity of providing individual medi cine bottles is eliminated, and which eliminates the necessity of the doctor handling individual medicine bottles, from which the odor of the different medicines is often transferred to the doctors fingers, the latter being over objectionable to both patient and doctor.
lVith these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claim. l
In order that those skilled in the art to which this invention appertains may understand how to make and use the same, I will describe its construction in detail, referring by numeral to the accompanying drawing forming a part of this specification, in which- Figure l, is a perspective view of my improved sanitary dental tray. Fig. 2, is a section at the line 2 2 of Fig. ,1, looking in the direction of the arrow, one of the ground glass tops being removed from its well, and
tacle; and Fig. 3, is a section at the line 3-3 of Fig. l, looking in the direction of the arrow, the waste receiver being removed.
In carrying out my invention as here embodied 2 represents the body of my improved sanitary dental tray formed from a single block of glass or other sanitary material of similar nature and supported in any suitable manner, the supports as here shown comprising four integral glass feet 3, one situated at each corner at the bottom.
In the body of the tray are formed a number of wells 4, the side walls of which preferably converge toward the bottom and said side walls adjacent their upper ends are made when the ground glass tops 5 are placed therein, each of said tops being provided with a knob or hand hold 6, whereby said ground glass tops may be readily and quickly removed or replaced. The body of the trayis also provided with two receptacles 7 and 8, the latter being provided with a channel 9 in which rest the edges of the cover 10, said cover lying flush with the top face of the body when in place. This cover is also made of glass and is provided with a knob or finger hold l1, whereby the same may be lifted to remove or replace it. The receptacle S which is closed by the cover 10 is adapted to receive and hold certain objects used in the dental profession, such as sanitary cotton pellets and by inclosing them in glass they are kept in a sanitary condition until they are ready for use. The receptacle 7 is adapted to receive a carton or other waste receiving device 12, so that waste, cotton or other objects may be placed therein, and when said carton is full, the same may be removed and thrown away.
Adjacent one edge of the tray is formed a longitudinal cavity or recess 14 in which are placed pliers and other instruments, when not in use, and because of the material from which the tray is made, said instruments are kept in a relatively sterile condition, because the tray is not likely to catch or retain dust or other foreign matter.
A tray of this character being made entirely of glass may be readily kept clean and in a sterile condition for it can be washed with hot water or acids to cleanse the same.
Having thus fully described my invention, what I claim as new and useful, is
In combination a glass body provided with the waste receiver removed from its recepground so that a perfect air tight closure is y a plurality of medicine wells, a cotton reamine@ my signature in the presence of tvvo ceivng receptacle, zn, Waste recelver receptasubscr1bing witnesses.
