'1 claims. (or 1 -236)A The invention relates to closet seat hinges, and has for an object to provide a strong, neat and durable hinge for a closet seat of the type having an open back, the hinge having an adjustable lock 5 bolt for preventing spreading of the seat and being easily adjustable to take up side play of the seat.

Another object of the invention is to provide a hinge having pintles retained against withdrawal by a ratchet connection.

The invention further consists in the several features hereinafter described and claimed.

In the accompanying drawing,

Fig. 1 is a top plan view of a closet seat struc- '15 ture embodying the invention;

Fig. 2 is a sectional View taken generally along the line 2-2 of Fig. l;

Fig. 3 is a sectional view taken along the line 3-3 of Fig. 1, and

Fig. 4 is a detail view of one of the hinge pintles.

In this drawing, 10 designates a water closet seat of the type having an open back, the gap at the back of the seat being formed between spaced parallel seat extensions 11. A cover 12, when '25' closed, nests within the seat to be substantially flush therewith at its upper surface, and is provided with a rear extension 13 disposed between the spaced extensions 11 of the seat. The seat and cover are preferably formed of wood, al-

, though other materials may be used.

The seat extensions 11 have aligned transverse bores 14 formed therethrough, and the cover extension 13 has a transverse bore 15 aligned with the bores 14 but of larger diameter. Ferrules or bushings 16 are pressed into the opposite ends of the bore 15 in the cover extension and are provided with flanges 17 bearing against the opposite side edges of the cover extension.

Brackets or standards 18 are secured to a 4@ closet bowl 19 by bolts 20 passing through the usual apertures in the bowl, resilient washers 21 being placed on the bolts to avoid marring of the bowl. The brackets 18 have eyed upper ends 22 which are placed between the seat extensions 11 and the cover extension 13.

at the heads of the pintles enter the seat extensions to prevent relative rotation between the pintles and the seat. The pintles extend through the brackets 18 and into the bore 15 of the cover, the pintles being journalled in the eyed ends of the brackets and tting in the ferrules 16. Washers 26 are carried on the pintles between the inner edges of the seat extensions 11 and the brackets.

The inner ends of the pintles 23 are cut away to form overlapping stems 27 of semi-cylindrical cross section, the adjacent faces of the stems being provided with interengaging ratchet teeth 28 permitting inward movement of the pintles but preventing their outward movement. The inner portions of the pintles are spaced from the walls of the bore 15 and are somewhat resilient to permit the relative inward movement of the toothed stems 2'7.

The closet seat when in use has a tendency to spread at its open back, but this is resisted by the interengaging ratchet teeth of the pintles on rods, the aligned pintles forming a bar connecting the rear ends of the seat. The brackets 18 are not subject to lateral pressure by reason of this spreading tendency. When the seat is assembled, the pintles are urged inwardly to take up lateral play, and this can be repeated, if necessary, after the seat is in use.

While the hinge of this invention is primarily intended for use with closet seats, it is not restricted to such use.

What I claim as new and desire to secure by Letters Patent is:

1. The combination, a closet seat having spaced rear ends forming an open back, a cover having a rear end between said seat rear ends, a pair of aligned pintles secured in said respective seat rear ends and extending into said cover rear end, said pintles having adjustably connected inner ends to` prevent spreading of said seat, and supports for said pintles.

2. In combination, a closet seat having spaced rear ends forming an open back, a cover having a rear end between said seat rear ends, a pair of aligned pintles secured in said respective seat rear ends and extending into said cover rear end, said pintles having overlapping ends provided with interengaging teeth to retain them together, and supports for said pintles.

3. In combination, a closet seat having spaced rear ends forming an open back, a cover having a rear end between said seat rear ends, a pai-r of aligned pintles secured in said respective seat rear ends and extending into said cover rear end, said pintles having overlapping ends provided with interengaging ratchet teeth preventing outward movement of the pintles but permitting their inward movement, and supports for said pintles.

4. In combination, a closet seat having spaced Cil fes

rear ends forming an open back and provided with aligned transverse bores, a cover having a rear end between said seat rear ends and provided with a transverse bore aligned with said first-named bore, a pair of headed pintles secured in the respective bores of said seat and extending into said cover bore, said pintles having adjustably vconnected inner ends to prevent spreading of said seat, and supports for said pintles disposed between said seat rear ends and said cover rear end.

5. In combination, a closet seat having spaced rear ends forming an open back, a cover having a rear end between said seat rear endsa pair of aligned rods secured in said respective. seat rear ends and extending into said cover rear end and having connected inner ends within said cover rear end to prevent spreading of said seat, and means for pivotally supporting said seat and cover about a pivotal axis substantially coaxial with said rods.

6. In combination, a closet seat having spaced rear ends forming an open back, a cover having a rear end between said seat rear ends, a bar connecting said seat rear ends to prevent spreading of the seat, said bar extending through said cover rear end, and means for swingably supporting said seat and cover about a pivotal axis substantially coaxial with said bar.

7. In combination, a closet seat having spaced rear ends, a cover having a rear end between said seat rear ends, a pair of aligned rods eX- tending into said seat rear ends and cover rear end and having adjustably connected inner end portions, and means for swingably supporting said seat and cover about a pivotal axis substantially coaxial with said rods.
