Specification of Letters Patent.

Patented July 14, 1908.

Application filed November '1, 1907. Serial No. 400,205.

I To all whom it may concern:

Be it known that I, PAUL WARRINGT N' EVANS, of Washington; in the District of Columbia, have invented certain new and useful Improvements in Dental Bracket- Tables; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

M invention relates to improvements in brac et tables for use of dentists,-the object of the invention being to so construct such a table that it canbe made .to contain. the operating tools and accessories used by a dentist, and in which they can be so arranged as to be readily accessible with theuse of one hand of the operator while the other hand isv en aged with the atient.

further object is to so construct a bracket table that the various instruments and acarts as hereinafter set forth and pointed out 1n the claims.

In the accompanying drawings, Figure 1 is-a pers' ective view of a dentist s bracket Fig. 2 is a plan view. Figs. 3 and 4 are sectional views taken at right angles to each other.

Fig. 5 is a view of one side of the device. Fig.

-. 6 is a view of another-side of the table, and Fig. -7 is a detail view illustrating one of the latch devices for holdingthe rods 17' and bars 16-elevated.

1 re resents the main or body portion of the ta le, which may beconstructed of any suitable material and divided into a series of compartments as hereinafter ex lained.

- This main or body portion 1 of the evice is secured u on a base bracket 2, the central -portion which is provided with a dependmg, tubular shank or stem 3 which passes through a suitable bracket arm 4 upon which the base bracket 2 is revolubly su '-2 E ported, whereby the table can be re '37 turned by. the operator as occasion may reuire. To the lower end of the tubular s ank 3 a gas supply pi e 5 is connected by means of a suitab e coup ing 5 and the tubular shank 3.communicates with. a duct 6 in the central portion of the base bracket 2. With this duct one end of a pipe 7 communicates, said pipe extending to one corner of the table an then upwardly through the table and rovided at a oint above the latter with a urner 8 and a racket 9 for the accommodation of an annealing tray or pan. An auxiliary adjustable burner 10 is also preferably provided and disposed over the table within convenient reach of the operator.

The table top consists of a slab 11 which may be made of enameled wood or steel, or-

thumb-nuts 13 screwe upon the upper ends of rods 14 which pass through said ars and the corners of the structure. Racks 15 are located upon the slab or table top 11 and are removably held in lace by bars 12. These rac table for preventing such tools from rolling. From this construction it will be seen that the slab 11 as well as the racks 15, can be readily removed when it is desired to cleansor sterilize them or when it is desired to place a different top upon the-table.

The bars 12 are rovided with removable sections 16, each oi which is attached at its respective ends to rods 17 which pass downwardly through suitable guide tubes 18 located within the table structure. The bar sections 16 can be raised to the position shown in Figs. 1, 5 and 6 and held in place by means of spring actuated latches 19 which engage notches 20 in the rods 17 as shown in Figs. 1 and 7. An elevated support is thus formed for the reception of a tray 21 which comprises a rectangular frame 22 and a bottom 23 of wire gauze. This tray is for the reception of tools or other devices for which the dentist may have immediate need and portions of theframe 22 are notched as shown at 24, Fig 6, to receive the handles of I tools for preventing the latter from rolling. By making this tra with a wire gauze or open-work bottom; ight may pass through it to the table top or slab 11.

The body portion 1 of the table is divided means of the having notches for the reception of dental tools upon the into a series of compartments 25, 26 27, and 28, by means of partitions suitably disposed, as best shown in Fig. 2. The coiniartments 25 and 26 will be normally closed by means of a-door 20 hin ed at the lower edge of the structure an provided with slotted arms 30 which move over ins 31. The door 29 may thus be disposer (when open) in a horizontal position and serve to support trays or instrument racks 32 33 when the latter are partially removed om the compartments 25-26 in which they are normally inclosed. The rack 32 comprises a frame which may be conveniently made of sheet metal and a series of trays 34 having wire netting bottoms arranged in step formation. The front edge of each tray 34 is provided with a series of notches 35 to prevent tools placed upon said trays from rolling. By making the trays 34 with wire gauze bottoms, all dust accumulation will be permitted to pass to the bottom of the structure 32. This rack or structure 32 is bodily removable from the table and can therefore be cleaned and sterilized whenever necessary. The tray 33 is ada )tcd for the reception of small articles whic the dentist may use in his practice and this tray is also bodily removable from the table and may be supported in a partially withdrawn position, b the door 20 in the same manner as the rate 32 is shown supported in Fig. 1. The compartment 27 at the opposite side of the table contains a series of rrawers 36 and in the compartment 28 a rack 37 is located and normall inclosed therein by means of a hinged oor 38. The rack 37 comprises side su iports 40, pivoted cross members 41 and let ges 42 upon which trays 43 are so ported. Stops 44 are provided so that when the lower portion of the rack is pulled outwardly the trays 43 will become disposed in step formation to give ready access to the small instruments which may be disposed upon said trays. These trays are removable and can therefore be thoroughly cleansed from time to time.

Projecting from two corners of the bod-v l of thedevice are receptacles 45 and 46. The receptacle 45 is made with compartments 47 and 48 for the reception of absorbent cotton rolls, and upon sair receptacle 45, a slab 46 is located to ermit the mixin of cement or amalgam. his slab is pro erably removable as is alsoa slab 50 located upon the receptacle 46 and these slabs may be used interchangeably u ion the rece )taeles 45 and 46. The slab 50 18 made witi a depression 51 for holding water for grinding )ur roses. The receptacle 46 contains a ste holder 52 for the reception of dental grim ing devices and polishing brushes. The receptacle 46 is normally closed by a door 53 and to this door a step holder 54, similarin construction and for the same purpose as the holder 52,

is secured. To the bottom of the receptacle 45 a spring clip 55 is located for holding glass floss silk holder.

Between the receptacles 45 and 46 a coinpartment 56 is located and the front of this compartment is normally closed by means of a door 57 while its top may be closed by means of a slide 58 mounte( in guide-ways 59 under the table top, the ends of said slide being also supported when the slide is pulled outwardly-to cover the compartment 56, by the u per edges of the receptacles 45 and 46. Within the compartment 56 a rack 59 for test tubes is located and in the bottom of this compartment a tray 60 is disposed. Within the com artment 56 and over the shallow tray 60 iolders 61 for burs, plugger points, reamers and the like are disposed. These holders comprise blocks or strips having sockets adaptable for the reception of the tools above mentioned and these blocks or stri s are removably held by means of socketer pivotally suplported blocks 62. With this construction t 'e holders 6]. can be tilted so as to dispose the tools in an inclined posh tion in which the o orator can most readily examine them to select the particular tool he desires to use. The door 57 of the compartment 56 is provided with several series of bur holders 63, one series disposed over the other and each holder adaptable for the reception of several burs.

5 At the corners of the table opposite the receptacles 45 and 46 are other rece tacles 64, 65. The door 66 of tho roccptac e 64 is preferably so hinged as to be movable in a iorizontal plane and carries a holder 67 similar in connection to the holders 5254 of the receptacle 46. The receptacle is provided on its top with a mixing slab 68 and to the bottom of this receptacle a book 69 is secured and rejects laterally therefrom, said hook being preferably so mounted that it can be pulled outwardly and serve to receive the arm of a dental engine and hold the same when not in use. This hook may also be utilized to temporarily hold a syringe. The receptacle 65 is provided with a compartment 720 for the reception of cotton balls or iellets and this compartment is made with a lateral opening. The receptacle 65 is also provided with a compartment 71 for the reception of loose absor ent cotton and the side wall of this com artment is provided with a series of slots 72 t irou h which particles of cotton can be withdrawn y the means of pliers. A box 73 is hinged at its lower edge to the lower edge of the rece tacle 65 and the top of this box is open for t ie reception of waste. ()no side or end of the box 73 is made with an irregularly shaped opening 74 to f aeilitate the insertion of waste and its removal from a dental tool.

Between the receptacles 64 and 65 is a compartment 75, the top of which is noring to t e slide 58 hereinbefore described.

A tray 77 is located in the bottom of the complartment and this tray is sub-divided for t e accommodation of mixing slabs 78, a sharpening stone 79, and for the reception of filling material.

Located within the compartment 75 is a series of spring supports .79, so disposed as to hold a horizontal series of removable wide-- mouthed bottles or jars 80 in an inclined position as most clearly shown in Fig. 4 and also as shown in Fig. 5. The cover 81 of each bottle or jar is provided with a cushion 82 to engage the mouth of the bottleor jar and said cover is pivotally connected to an arm 83. Each arm 83 is pivotally supported by lugs 84 andprovided with a cam projection 85 engaged by a spring 86. Withthis construction, it Will be seen that the operator can, with the use of one finger raise a cover from a bottle or jar by manipulating thearm 83 and that he can again close the bottle or jar by pressing downwardly on said arm.. By pivotally connecting ,-"the covers 81 to the arms 83, said covers will adapt themselves to the bottles or jars even though the latter may be slightly misplaced within the holders. The compartment 75 will be normally closed bymeans of a hinged door 87.

One or more handles 88 may be provided whereby the operator canreadily rotate the table. I o

. With the use of my im rovements the dentist will haveall of his lnstruments and accessories systematicall arranged and within convenient reach so t at he can take them with one hand while the other hand is en-.

gaged with the patient. It is also apparent that the various holding means provided can be kept clean and sterilized.
