WALTER H. HENDRICKSON, F ROCKFORD, YILLINOI S, ASSIGNOR TO ABINGDON ENGINEERING CORPORATION, OF ABINGDQN, ILLINOIS, A CORPORATION OF ILLINOIS r CONCEALED DAVATORY Application filed. January 6, 1930, Serial No. 418,701. Renewed October 8, 1932;

This invention relates to a concealed lavatory wherein the wash-bowl is pivotally mounted to fold from an extended position up into a cabinet.

In concealed lavatories of this kind'it has been found that there is a tendency forthe user to swing the bowl out carelessly, allowing the bowl to drop to extended position, and thus cause damage or breakage to the; bowl or its mounting. It is, therefore, one important object of my invention to provide a counterbalancing checking device of a relatively simple and inexpensive form arranged to support the bowl in any intermediate poto move the bowl all the way from one posi tion to the other, and make it absolutely, impossible for the bowl to drop. The bowl, in order to fold into the shallow cabinet, is pivotally mounted on swinging hangers, and, according to my invention, the checking devices are built into the hangers as unitary assemblies.

Another difficulty with these lavatories has been that of keeping the waterfrom splashing out when the bowl is dumped into the hopper provided for that purpose in the cabinet. Screens or baflies have been provided inside the hopper to prevent it, but were not found to be satisfactory for the purpose and were, furthermore, objectionable in that they would soon get dirty and it was unhandy to remove the same for the cleaning thereof. Moreover, the hopper could not be cleaned without first removing the screen or baffle. According to my invention, I" provide an inwardly projecting ledge on the walls ofthe hopper near the top thereof which the water is arranged to strike and be therebyv de: flected and the force thereof broken so that no water will be splashed onto the user or onto the floor. A hopper made in this way can be cleaned easily and thereis, therefore, less likelihood of its harboring odors. j The foregoing and other objects and adsition so as to make it necessary for the user vantages of my invention will appear in the course of the following specification, in which reference is made to the accompanying drawings, .wherein Figure 1 is a vertical section through a con- 'cealed lavatory embodying my invention; Fig. 2is an enlarged section through one of the side housings, in which the hanger supports for the wash-bowl are provided, the hanger and the cam associated therewith, together with the counterbalancing checking device built in the hanger being shown in central longitudinal section approximately on the line 2 -2 of Fig. 3;

Fig. 3 is a transverse section taken on the broken line 3-3of Fig. 2, and

F ig. 4 is anothertransverse section on the line 4-4l of Fig. 2, but showing the parts in shifted positions-corresponding to the lowered position of the bowl.

The same reference numerals are applied to corresponding parts throughout the views.

Concealed lavatories are well known, and no lengthy description outlining the pur poses and advantages thereof seems necessary. Itwill suflice to state that it is common practice to provide a cabinet consisting of acasing 5 vwith or without shelves in the upperend thereof and providing a hopper 6 in the lower end. A panel 7 conceals the hopper .andthe trap 8 therefor when the casing 5, is set in the .wall, as by fastening the same to'the studding. Folding doors 9, flush with the panel 7 and the front of the casing5,.are 'arranged to be opened to permit the lowering of the wash-bowl 10 from the folded position shown in full lines to the extendedposition indicated in dotted lines. The bowl is preferably made of white china or white porcelain enameledsteel. A faucet 11,- preferably of the mixing type, is so located that it fits in the hollow of the bowl when the latter is folded into the cabinet and is arranged to deliver water to the bowl when the same is lowered for use. The back 90 of the bowl is provided with a discharge opening 12 so that when the bowl is raised in the folding thereof into the cabinet, the waste water is discharged into the hopper 6. The usual pipe connection 13, communicating with the trap 8, avoids any likelihood of an overflow. As stated above, it has been found that users of this type of lavatory are often apt to raise the bowl so quickly that water is apt to be splashed out of the hopper onto the user or onto the floor. Screens or baffles, provided in the hopper to prevent such splashing, were not found to be very satisfactory and were, moreover, a nuisance from the standpoint that they were unhandy to clean and made it difficult to clean out the hopper. According to my invention, I provide an inwardly projecting ledge 14 on the front and side Walls of the hopper 6 near the upper end thereof which the water discharged into the hopper is arranged to strike on the rebound or back splash and be thereby deflected and the force thereof broken, so that none of the water is apt to splash out. If desired, the top of the ledge 14 can be used as a place for supporting a removable hood such as that indicated in dotted lines at 15. Any fine spray that might otherwise escape from the hopper would most certainly be caught by the hood. However, in actual practice I find that the hood can be dispensed with.

The wash-bowl 10, in order to fold into a shallow cabinet, cannot have a plain trunnion 1 mounting, unless the back of the cabinet is r the side walls thereof for the reception of bolts 19 by means of which the housing is secured to the side wall of the casing. The hanger 16 comprises a pair of spaced side plates or links 20 mounted on a hinge pin 21 suitably supported in the upper end of the housing as shown. Slots 22 are provided in the lower ends of the side plates and have the lower ends thereof formed to provide semi-circular V-shaped seats 23 for the reception of concentric V-shaped annular bearing portions 24 provided on a cam shaft 25. The latter constitutes one of the two supporting trunnions for the bowl 10, as will now be explained. A sleeve 26, square on the outside thereof but having a circular bore, is slidably received in a square hole 27 provided in the center of a plate 28 fastened, as by means of screws 29 entered in grommets 30, to the depending side flange on the bowl 10. The sleeve 26 enters a square socket 31 provided therefor in the outer end of the cam shaft 25, and the bolt 32 passing through the sleeve 26 and threading in a center hole in the shaft fastens the sleeve rigidly to the shaft. Thus, when the bowl 10 is moved from its one position to the other, the sleeve 26 turns with it and turns the cam shaft 25. Now, an elongated opening 33 is provided in the side wall of the casing 5 through which connection is made between the sleeve 26 and shaft 25, and this opening is sufficiently elongated to permit the amount of fore and aft movement communicated to the cam shaft by a cam 34 preferably formed integral with the end of the shaft immediately adjacent the sidewall of the casing. The cam 34 is substantially triangular in form with the apex 35 arranged to ride on an abutment pin 36 suitably carried by a boss castintegral with the adjacent wall of the housing 17. The ends 37 of the base portion of the triangular cam and portions 37 of the sides thereof near the apex 35 are formed to serve as stops for limiting the turning of the cam to approximately of movement, the base portion of the triangular cam being arranged to ride on'another abutment pin 38 similar to the pin 36 in the turning of the cam until either end 37 arrives at the pin, whereupon further movement of the cam is prevented. Obviously, as

the apex portion 35 of the cam rides over the pin 36 from one side to the other, the shafts 25, constituting the trunnions for the bowl 10, are given movement in a fore and aft direction. This insures clearance for the inner end of the bowl with reference to the back wall of the casing in any position of the bowl, and the bowl can be folded to a position quite close to the back wall, as indicated in Fig. 1. A closure plate 39, fitting snugly about the end of the cam shaft 25, is arranged tosealthe housing 17 at the opening 33 in any position of the cam shaft with reference to said opening, so that there will be no danger of any moisture getting into the housing and causing the working parts of the hanger to get rusty and Work hard and noisily. A plurality of bowed leaf springs 40 are seated in recesses 41 provided in the side face of the cam 34 and bear against the inside ofthe plate 39 to hold it in snug engagement with the side wall of the casing to insure the proper seal While still allowing sliding movement of the plate on said wall and movement of the bowl are preferably built in the hangers 16 as 1 unitary assemblies. Both of these devices are of the same construction, so that reference need be made only to the one shown. A plunger 42 has a yoke 43 provided on the lower end thereof so as to reach around the cam shaft from above the same for connection with a crank pin 44 mounted in arms 45 preferably cast integral with the cam shaft. The lower end of the yoke 43 is forked, as indicated at 46, to straddle the pin 44. The upper end of the plunger 42 is slidably received in a hole 47 provided in a swivel block 48. The latter has trunnions 49 onto which the upper ends of the side plates 20 of the hanger 16 are arranged to be hooked, as shown at 50, the edges of the plates being cut away to provide the hooks for that purpose. A coiled compression spring 51 fits about the plunger 42 and rests at its lower end on an annular shoulder 52 provided on said plunger and at its upper end engages another annular shoulder 53 provided on the swivel block 48. When the bowl is moved from the folded position shown in full lines in Fig. 1 through approximately tothe dotted line extended position, the cam shafts'2'5 on the opposite sides of the bowl are, of course. turned through the same angularity, thereby throwing the crank pin 44 from the position shown in Fig. 3 to that shown in Fig. 4, an angularity again equal to 90. Analyzing the operation of the counterbalaneing or checking device which results from this movement of the crank pin 44, it is evident that the pin'44 is in line with the trunnions 49 and the center of the cam shaft 25 when the bowl occupies the folded position (see Fig. 3), and that the plunger 42, regardless of the pressure of the spring 51, is in a neutral position so far as its having any effect on the bowl is concerned. However, when the bowl is lowered the least bit, the crank pin 44 is moved out of alignment with the center of the cam shaft and the ,trunnions 49, the moment arm with reference to the center of the crank shaft increasing proportionately as the bowl is lowered more and more and the pressure of the springv 51 also increasing proportionate ly, because the spring is compressed more and more, as the bowl is lowered. As a matter of actual fact, the moment arm and the pressure of the spring efiectii e thereon in any position of the bowl between its raised folded position and its lowered extended position are such that the bowl is accurately counterbalanced and will hold any position to which it is moved. By virtue of this counterbalancing effect, it is naturally a very easy matter to raise the bowl and move it to folded position. since the weight of the bowl is counterbalanced and, to move the same, it is only necessary to overcome the frictional resistance. The construction of the counterbalancing or checking device is obviously ex- 1. A device of the character described,
