' SINK POSITIONING MECHANISM Filed Dec. 4, 1950 2 Sheets-Sheet 2 Patented June 21, 1932 PATENT OFFICZE EDWARD N. CAVERT, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-THIRD T SAMUEL PETERSEN AND ONE-THIRD '10 GEORGE B. ARCHER, BOTH OF CHICAGO, ILLINOIS SINK POSITIONING MECHANISM Application filed December 4, 1930. Serial No. 499,920.

This invention relates tosink positioning mechanism, and more particularly to manually operable means for quickly and conveniently changing the relative height of a kitchen sink or the like. A more particular object of the invention is to provide means by which the elevation of a sink may be changed to suit the height or convenience of the person using the sink at the particular time. It is impossible to permanently install a kitchen sink that will be of a height to suit all individuals, and as a result a great deal of fatigue and tedium occur when a housewife or servant is compelled to use a sink that is positioned either too high or toolow. It is to overcome this problem and provide simple yet practical and durable means for enabling the sink to be raisedor lowered to any desired level to suit any particular individual, that the present invention is directed. It will be understood that this is of especial advantage in apartment buildings where a change in occupants of an apartment occurs frequently.

Other objects will appear hereinafter.

This invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which:

Fig. l is a plan view of a typical kitchen sink, with the mechanism of the present invention applied, taken substantially on the line 11 of Fig. 3;

Fig. 2 is a vertical sectional view taken substantially on the line 2-2 of Fig. 1;

Fig. 3 is a vertical sectional view taken at right angles to Fig. 2 centrally of the operating mechanism; and

Fig. 4 is a perspective view of the supporting frame, slidable block, and operating screw of the apparatus.

The preferred embodiment of the invention is shown in operative association with a kitchen sink 6 provided with a drain pipe 7. These parts are adapted to be moved vertically to any desired position and rigidly maintained at such selected elevation, and the mechanism for providing this operation pref} a erably comprises a supporting frame 8 which may be secured in place within a wall by means of bolts or screws 9 extending through opening '10 and secured to the vertical joists. As shown, the supporting frame 8 includes a lower transverse brace 11 and an upper transverse brace 12. The upper brace member 12 may be provided with openings 13 for receiving and supporting the water supply pipes 14 connected to the faucet 15. Inasmuch as the pipes 14 and faucet 15 are stationary, the splasher portion of the sink 6 is preferably provided with a vertical slot 16 for each pipe 14:, and to prevent this slot opening on the exterior surface, a spring plate 17 is preferably secured adjacent the base of the faucet 15 and is adapted to conform'to the surface outline of the adjacent splasher portion of the sink in any elevated position.

The means for raising and lowering the sink in the preferred embodiment comprises a block member 18 which is formed with lateral channel portions 19 adapted to embrace the vertical portions of the frame 8 and thus serve to guide the block 18 and also maintain the same rigidly in any position. The sink 6 may be secured to the block 18 by means of a plurality of relatively heavy screws '20 which pass through the block 18, as shown,

and are threaded into rearwardly extending bosses 21 integrally formed on-the rear wall of the sink. Vertical movement of the block and connected sink at this point is permitted by reason of vertical slots 22 in the wall surface 28 to accommodate'the screws or bolts 20. The block 18 is provided centrally with a vertical internally threaded portion to engage the threaded portion 2a of vertically disposed operating screw 25 which is journaled intermediate its length in opening 26 of brace 11, and at the lower extremity is provided with a reduced portion 27 journaled in the bracket 28 suitably secured interiorly of the wall. The lower extremity of the operating screw 25 carries a bevel pinion 29 adapted to mesh with bevel pinion 3O securedto shaft 31 journaled in bracket 32. It will be noted that shaft 31 extends through the wall 23 and has secured thereto a hand operating wheel 83 positioned adjacent the wall surface.

In the preferred embodiment shown, the drain pipe 7 is adapted to telescope within the stationary drain pipe 3% which is connected to trap 35 as in the usual construction. The upper extremity of the stationary pipe 34: is preferably threaded for engagement with the internal threads of bushing nut 36, having a reduced upper annular portion 37 adapted to embrace the drain or outlet pipe 7 and to con fine the packing 38 preferably provided to render the joint leakproof in any position. As shown, the nut member 37 carries laterally extending arms 39 by means of which the member may be manually tightened or loosened.

The operation of the device is largely indicated by the foregoing description. To selectively position the sink 6, it is but necessary to loosen the nut 36 which may be done by means of the arms or handles 89 and then turn the positioning Wheel 33, to bring the sink to any desired elevation. When the selected position has been reached, it is but necessary to tighten the nut 36 to provide a leakproof joint through the drain connection.

' While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. 1, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. Incombination, a sink, an outlet pipe for said sink, a stationary drain pipe, means for providing a leakproof connection between said outlet pipe and said drain pipe at any selected elevation of said sink, a stationary supporting frame, a block member slidably mounted upon said supporting frame and connected to said sink, and a vertically extending screw member in threaded engagement with said block member for raising or lowering said block member and sink to any selected position.

2. In combination, a sink, an outlet p1pe for said sink, a stationary drain pipe, means for providing a leakproof connection between said outlet pipe and said drain pipe at any selected elevation of said sink, a stationary supporting frame, a block member slidably mounted upon said supporting frame and connected to said sink, a vertically extending crew member in threaded engagement with said block member for raising or lowering said block member and sink to any selected position, and manually operable means for rotating said screw member.

3. Sink positioning mechanism of the character described comprising, in combination, a sink mounted adjacent a wall surface, a supporting frame rigidly mounted within the wall rearwardly of said wall surface, a block member slidably mounted for vertical movement upon'said supporting frame, a rigid connection between said sink and said block member extending through a vertical opening in said wall, operating means connected to said block member for raising and lowering the same, and manually operating means mounted exteriorly of said wall surface for actuating said operating means.

4. Sink positioning mechanism of the character described comprising, in combination, a sink mounted adjacent a wall surface, a supporting frame rigidly mounted within the wall rearwardly of said .wall surface, a block member slidably mounted for vertical movement upon said supporting frame, a rigid connection between said sink and said block member extending through a Vertical opening in said wall, a vertically extending screw member in threaded engagement with said lock member for raising .or lowering said block member and said sink to any selected position, and manually operable means mounted exteriorly of said wall surface for actuating said screw member.

In testimony whereof I have signed my name to this specification.

EDWARD N. CAVERT.
