CUSPIDOR.

' fol owing is a specification.

The invention, relates to a cuspidor adapted to. be secured and supported, with the usual supply, Waste and overflow pipes, on a bracket on the side of a dental or other In cuhpidors of this type, it is desirable to arrange the cuspidor and its sev- 'eral pipes so that the same can be gyrated on an independent axis inaddition to'being swung on the supporting bracket to various positions at the side of the chair, and it is also desirable that the cuspidor parts shall bejwell balanced on the' axis of gyration so there will be no binding of the parts when rotated. These objects are atroviding a Y-shaped cuspidor bracket which is swiveled by its stem on the ordinary swinging or supporting bracket, and by securing or mountin the cuspidor bowl on one branch of the bracket and the supply pipe on the other branch thereof. In such cuspidors the bowl-flusher and saliva-ejector ipes are usually extended from the outer si e over the rim of the bowl and thence downward therein, and the overflow.

. a pipe is usually connected to the ide wall of the bowl, which arrangement and connection of these pipes renders it diflicult to rotate the bowl on or to detach and remove it from its bracket support. 'These difliculties are overcome by providin a vertical guidebearingon the cuspidoi' racket, in which a a slide section of the supgly pipe is adapted '40 to be secured'and adjuste endwise, whereby "the flusher and e ector pipes can be elevated above the bowl, which permits the same to be freely detached and removed; and by connecting the overflow pi e with the over-flow channel in the bracket y a. free telescoping .tube. so that this connection canbe severe either by sliding the tube u ward on the 'pipe or by lifting the pipe irectly out of the tube. V

The cuspidonbowls are usualtliy made of assf'porcelain or'other hard in exible maer' a], and it is diflicult' to properly connect the overflow pi e in the aperture'therefor which ia.pr ov1 ed in the side wall of the Specification of Letters Patent.

of the bowl whether the same is trul cylin- -dric or is flared upward or downwar And finally, it is difficult to connect the bowl on its supporting bracket, which is usually made 0 cast iron or other hard inflexible material, without shaping or grinding the connected parts to neatly fit each other or em loying some form of packin to make a tight joint which will not tend the brittle body of thecuspidor. This difficulty is overcome by roviding an intervening collar made of s eet metal or other flexible and preferably elastic material, the lower end of which is suitably secured to the bracket and the upper end of which is flared in the form of an inverted bell and adapted to receive and support on its upper rim the to break;

the flexibility of the -collar permits its edge to neatly fit the neck of the bowl; and by providing an external annular rib on the endof the neck of the bowl and a series of inward protrusions in the flexible collar which are adapted to be sprung over and to I clamp the rib on the end of the bowl neck.

The various features of the invention, thus set forth in general terms, are illustrated with respect to a preferred embodiment of the same in the accompanying drawings, forming part hereof, in which- Figure 1 is a perspective view of the improved cuspidor; Fig. 2, an elevation of the same with some parts in section to show details; Fig. 3, a fra mentary section show-1 ing the overflow was as applied to. a bowl havin cylindric side walls; Fi 4, adetache perspective view of the exible collar; Fig. 5, an elevation section of the collar showing the referred method of clamping the bowl nec therein and of securing the collar to the cuspidor bracket; and Fig. 6, a transverse section of the flexible collar on line 66, Fig. 5;

'Similar numerals refer to similar parts throughout the drawings.

The 'cuspidor bracket 1 is formed with the stem 2 and two diverging branches 3 and 3, on one of which the cuspidor bowl a is secured and to the other of which the supply pipe and the overflow pipe 6' are respectively secured and connected. The

' waste channel 7 and the overflow channel? are provided in the respective branches of the bracket and merge to form the outlet channel 8 in the stem thereof, which outlet channel in turn leads to the waste pipe 9 which is connected to the stem of the bracket.

The stem of the cuspidor bracket is swiveled in the free-end bearing 10 of the chair bracket 11, the other end 12 of which bracket is pivotally mounted on the pintle 13 which is suitably secured to'the chair, not shown, as by means of the arm 14. And

- the'cuspidor bracket is so proportioned and tached on the overflow branch of the cus-- pidor bracket, in which bearing theslide section 5* of'the supply pipe is adapted to be secured and to. be adjusted endwise, as by means of the set screw 16 operating through the bearing and into the longitudinal channel 17 provided in the side of the supply pipe section. This connection and arrangement of the supply pipe permits the same to r be adjusted downward and upward to bring ,the discharge ends of the loowl-flusher pipe 18 and the saliva-ejector pipe 19 into proper operative position inside the bowl, as shown in Fig. 1, or to elevate them freely above the bowl as shown in Fig. 2. And by turnmg the set screw out of the pipe'section channel, it is evident that when the flusher and ejector pipes are raised abovethe rim of the bowl, the supply pipe can be rotated in its bearing as may be desired;

The overflowpipc 6 which depends from the side wall of the cuspidor bowl, is connected with the overflow channel in the cuspidor bracket by means of the intervening 'tube 20, which telescopes in the cylindriccountersink 21 formed in the bracket, and also around the lower end of the overflow pipe. It is evident that by merely raising this tube out of the bracket countersink, as shown by broken lines inFig. 1, the cuspidor bowl is free to be rotated on its central support; and also that when the cuspidor'bowlis raised from its bracket support, the overflow pipe can be lifted freely out of the tube, as shown by broken lines in Fig. 2.

The overflow pipe is connected to the side wall of the bowl by means of the inturned upper end- 6 which extends through the overflow aperture 22 which is provided in the wall. This end of the pipe is provided with threads on which the nuts 23 are adapted to operate, one being located inside and the other outside the wall. Intervening between the nuts and each side of the wall are provided the washers 24 and preferably also the resilient packing rings 25. The body of each washer is made thicker on one side than the other, with the beveled or inclined inner face 26 presented toward thewallof the bowl, and the peripheral flange 27 is preferably provided around the same face which serves to hold the packing ring in place. When the parts are assembled, the washers and packing ringsfare clamped against the sides of the bowl wall, thus making a water-tight and secure joint therewith.

It is evident that by the use of the wedgeshaped washers, the overflow pipe connection can be adapted to bowl walls of different shapes. For instance, when the wall is flared upward and outward, as shown in Figs' 1 and 2, the outer washer is arranged with its thinner edge upward and its thicker edge downward, while the inner washer is reversely arranged; which relative arrange.- ment of the outer and inner washer is reversed in case of. a side-wall which flares downward and outward. And if the con.- nection is made with a cylindricfwall, the washers are arranged with the thin edge on oneside and the thicker edge on the, other, as shown in Fig. 3, which arrangement of course deflects the upper end of the outlet pipe slightly out of a radial line, but this deflection is so light and unimportant as to be negligible. t The cuspidor bowl 4 is secured on the branch 3 of the-cuspidor brac-ketby means of the intervening connecting collar 28 made of sheet metal or other similar flexible and elastic material. The connecting collar is preferably secured in the socket 29 formed,

is preferably made in the form of a cylinder,

whencevv the upper end vportion is flared-upward and outward in the form of an inverted bell to receive the'similarly shaped neck 34 of the bowl. A series of preferably three inward protrusions 35 are provided around the cylindric lower end portion of the collar, preferably :Kljilttlll' to the angle of the flared upper end portion thereof,

upon the upper rim of the collar before the the stem being swiveled'in the free end of outlet channel in the 'stem of the cuspidor Jconnected with the ,otherbrhnch, there bewhich protrusions are conveniently made 'by inwardly indenting the collar, as shown.

The neck 34 of the cuspidor is flared upward and outward in such a'manner that when it is inserted in the connecting collar, the bowl will come in contact with and rest lower endof the neck comes. in contact with the inturned flange of the collar, and the lower portion of the cuspidor neck is formed less in diameter than the collar, so that it does not contact with the wall of the-same below the upper rim portion thereof. The annular rib 36 is provided around the lower end of the cuspidor neck, the middle portion of which rib is formed larger in diameter than the diameter of the protrusions in the collar, but slightly less than the adjacent wall of the collar, from which middle portion the upper and lower sides of the rib are beveled or inclined inward; and the parts are so arranged that when the cuspidor neck is inserted in the collar, the annular rib will first force the protrusions on the collar outward until the same have passed over the wider middle portion of the rib, which is permitted by an annular distortion or that te'ning of the lower end of the collar between the protrusions; after which the protrusions will contract inward on the upper inclined side of the rib, against WhlCh they are clamped by the elasticity of the collar, when the neck of the bowl impinges the rim of the collar. It is evident that by this construction and arrarigement, the rim portion of the collar quite readily conforms and adapts itself to the exact shape of the impingingportion of the cus idor neck, against which the rim portion 0 the collar is clamped by the action of the protrusions in its lower end on the inclined upper side of the neck rib; and also that while the bowl is normally held securely in position, it can be readily removed from the collar by merely lifting it out of 'the same with sufficient force to again deflect the protrusions to pass over the wider middle portion of-the rib.
