SPRING ATTACHMENT FOR TOILET SEATS Filed July 23. 1954 2 sheets-sheet 2 United States Patent @dice Patente SPRING ATTACHMENT FOR TOILET SEATS Lewis J. Mercur, Miami, Fla.

Application V.uly 23, 1954, Serial No. 445,359

2.Claims. (Cl. 4 251) The present invention relates to `improvements in attachments to toilet seats which L,permit'the seat to be automatically raised to a vertical position, y,but which may be held down when the cover for the seat islowered Yover the seat.

Many devices have been Ypromulgated'for the purpose of raising a toilet seat from the 'horizontal position to a verticaleposition and many `arrangements of springs and counterweights have been suggested and experimented with in an effort to provide a device which would attach to seats of all compositionsand which -would raise the seat to a non-usefpositionwhen thelid wasiraised.

Accordingly, the primary and principal object of the present'invention "isto' provide a'device which is `capable ofbeing attached to seatsv ofall sorts of ycomposition and whichis adjustable to'raise theseat to-a-verticalor non use position-whenever thellid or topfof-the toiletis'raised, or `may'be used-in-a toiletwithout alid.

Another A objectof the present -invention is to fprovide a-deviee which may be -usedwith'the-fexisting \seatsup porting shaft without anyalteration lwhatever, and `one which may be adjusted for any Weight of seat.

A further object of the present invention is to provide a device which will permit the seat to be raised to a vertical position, but will present a resilient restraint for further movement beyond the vertical, in order that bothersome banging and thumping of the seat on the water tank be avoided.

A still further object of the present invention is to provide a simple and easily assembled device which is easily secured in place on the shaft of such a toilet having a seat thusly supported, and one which may be as readily removed and used on any other similar seat and toilet bowl without particular alteration of either the seat or toilet.

These and other objects and advantages of the present invention will be readily apparent on consideration of the following description and the annexed drawings, in which like reference characters indicate like parts throughout the several views and in which:

Figure 1 is a side View in elevation of the present invention in place on a toilet bowl of conventional design.

Figure 12 is anend view of the spring of Figure 11.

Figure 13 is aside view of the Smaller-.spring ofthe invention.

Figure 14 is an end view rof the smallerspringtshown `in Figure 13.

Figure 15 is a detailed ,viewinsideelevatoll 0f Aone of the parts of the presentinvention, as will be hereinafter more clearly described, ,and

Figure v16 is `a detailed `viewirrcross section takenton line 16V-16 of vFigure 5.

Referring tothe drawings in greater detai la toilet bowl is indicated. generally ,by the reference character 10 and a seat 33 is swingablyhingedthereto by means of the shaft 11 which has /itsopposite Vend s ,12 and 13 fulcrumed and anchored in the shaft supports 14 and v15, respectively.

No lid is shown in-the embodiment here illustrated, but it'isjcontemplated that a lid forthe seat may .be used withfthe `present invention, and if so, would also 'be swingably securedv to the same shaft l1'1. lFor the pur poses of illustration, the shaft 1-1is'seen' to have on" it a sleeve 16 Vextending from each seat-bracketj-17 and 518, and if any lidwere'a'part ofthevtoilet,attachment its brackets would beeinte'rposed one-each between the seat brackets 17 and 18 and the -sleeve1 .6, ornpreferablyibetween=theseat brackets =1'-/';an`d l18 --and the 'shaft supports 14 andllS,*bothrespec-tively. i

vAtcollar 19is-securedby s crew'Zlwto the-sleeve I16 andononeside ofthe collars1s9is-formedangextension or arm fhaving LbifurcatedV ends -to gowone Aeitherside of one `oftthesupports,i1;4;in this ease.V

The collar 19 is formed with a hole 22 which receives a pin 23, and an annular member 24 slides on the sleeve 16 in confronting face to face relation with the collar 19, the member 24 being formed on its confronting face with a plurality of recesses 25 which receive the pin in any one of several adjusted positions. The member 24 has a series of holes 26 on its periphery in which a tool may be inserted for the purposes of rotation of the member to any position where the pin 23 may be secured in any one of the recesses 25. The other non-confronting face'of the member 24 has an aperture 27 receiving one end of a helical spring 28 which has its other end bent into an offset portion 29 and extends outwardly at its free end 31 to where it is attached under a bracket 32 to the seat 33, on the underside thereof.

The sleeve 16 has at its other end remote from the collar 19 and member 24 a clamp 34 which is adjustably secured on the sleeve 16 by means of the nut 35 and bolt 36. One side of the clamp 34 has a pair of lugs 37 for the purpose of holding the free end 38 of a second helical spring 39 also positioned on the sleeve 16, the other end of the spring 39 being formed with a detent section or loop portion 41 which receives the offset portion 29 of the rst spring 28 when the spring 28 swings the seat upwardly towards the vertical position, most clearly indicated in Figure 1, but also in Figure 2 where the seat brackets 17, 18 are shown in section to indicate a raised position.

A washer 42 separates the clamp 34 from frictional end engagement with a housing 43 which encloses the springs 28 and 39 and has a slot along its length and for a portion 44 of its width in which the end of the spring 28 is movable. The washer 42, being interposed between the spring 39 and the clamp 34 has a cut-out notch 45 for passage of that end of the spring into the clamp 34 where it is held and by means of the clamp 34, the tension of the spring 39 is adjustable so that when the seat is either released from a horizontal position or aided in its upward movement by a light lifting motion, the spring 39 engages at its loop portion 41 the offset 29 of the main spring Z8 as it nears the vertical position, and being of heavierrconstruction or greater tension, the spring 39 prevents the seat from violently hitting against the tank of the toilet, indicated by the reference character 46.

The operation and installation of the present invention is believed to be clearly obvious from the foregoing. Mere removal of either one of the shaft supports 14 and 15 from the toilet bowl, and slipping the Iassembled invention on the shaft, with attachment of the end 31 of the spring 28 under the bracket 32 on the seat 33, completely installs the invention, and its removal therefrom is equally las easy.

While a single embodiment of the invention has been here illustrated and described, other embodiments are contemplated and many changes and modications of the device may be made and practiced without departing from the spirit and scope of the present invention as more particularly set forth in the appended claims.

What is claimed is:

1.
