CQNCEALED-STOP HINGE.

Application filed January 1, 1923.

To all whom it may concern:

Be it known that I, DUDLEY S. VVARTH, a citizen of the United States, and a resident of the borough of Brooklyn, Kings County, city and State of New York, have invented an Improvement in Concealed-Stop Hinges, of which the following is a specification.

My present invention relates to hinges for the seats of water-closets and the like.

which hinges are provided with concealed stops, and aims to provide devices of the character described which shall be simple in construction, little liable to get out of order and require repair, which shall have smooth exterior surfaces and thus be adapted to be readilycleaned, andwvhich shall prevent the seat from striking the flush tank, the flush pipe, the flush valve, or the wall or other object adjacent to which the seat may be mounted.

.In the accompanying specification I' shall describe, and in the annexed drawing show, several illustrative embodiments of the present invention. It is, however, to be clearly understood" that my present invention isnot limited to the particular embodiments thereof which are herein shown and described for purposes of illustration only. i

Referring to the drawings, in which the aforesaid illustrative embodiments of the present invention are shown 2 Fig. 1 shows a plan view, partly broken away, of one of the aforesaid illustrative embodiments of the present invention as ap plied more particularly to a divided watercloset seat;

Fig. 8 is a top plan view of the pintle post shown in Fig. 7

Fig. 9 is a transverse section of one form of hinge post that may be used with the illustrative embodiment of the present invention shown in Figs. 5 and 6 of the drawing; and

Fig. 10 is a cross-sectional view of the hinge post shown in Fig. 9.

Before describing in detail the aforesaid illustrative embodiments of the present in vention, it may be desirable briefly to point out the disadvantages of the devices used in the prior art for accomplishing the same general results intended to be accomplished by the devices of the present invention. As far as I am aware, all of the stop hinges hithertoemployed or suggested for use in connection with water-closet seats and like devices have had embodied therein external visible attachments which are cumbersome, which render such hinges expensive to manufacture and difficult to attach, which are very liable to get out of order and to requirev pose, are obtained in a simple but highly ingenious manner. a

Referring first to the illustrative embodiment of the present invention shown in Figs. 1, 2, 3 and 4: of the drawing, S indicates a vided construction type. comprising the two

members

10 and 11. The

members

10 and 11 are held together in properspaced relation with respect to each other by means of the hinge generally designated by reference character H.

In the illustrative form now being described, thehinge H comprises a bar 19. having attaching plates 13 and 1t in the form of fins or extensions which are attached to the

respective seat members

10 and 11 by means of the screws or other suitable fastening devices 15.

As a part of my present invention I provide concealed means for limiting the angle through which the seat can be rotated in at least one direction, as in an upward direction, but preferably in both directions, that is in both the horizontal and raised positions of the seat, so that the same will be stopped and maintained in the desired position or positions by means concealed within the hinge structure itself.

For this purpose I provide the bar 12 with the pintles 16 at each end of the same. Preferably, the pintles 16 are integral with the bar 12, as are also the fins or attaching plates 13 and 1 1-, so that the bar 12, the fins or attaching

plates

13 and 14, and the pintles 16, may be cast in a single piece.

In the illustrative form now being described, each pintle 16 is of substantially circular cross-section adjacent its inner end 17, where it joins the rod 12, and has a re-' duced end portion 18 which is preferably of semi-circular cross-section.

Cooperating with the pintles 16 are a plurality of hinge posts 19 having the threaded rods 20 adapted to pass through the porcelain, of the bowl and to be held in position in the bowl by any suitable fastening means, such as nuts and washers, or the like, not here deemed necessary to be shown, in the manner well-known to those skilled in the art to which the present invention relates.

The upper portion of each hinge post 19 comprises a flange 21 and a head 22 provided with a transverse socket The socket 23 contains concealed therein means cooperating with the pintles or other equivalent remaining portions of the hinge structure for limiting the angle through which the seat can be turned in either direction, up or down, corresponding to the horizontal and raised positions of the water-closet seat, respectively. For this purpose the socket 23 is of substantially circular cross-section adjacent the outer portion 24 thereof, corresponding to the substantially circular cross-section of the pintles 16 adjacent the inner end 17 thereof. Adjacent its inner end 25, the socket 23 is of reduced crosssection, as in the form of a reentrant angle. For this purpose the socket 23 is provided with a boss or projection 26 extending from the base 27 part way towards the outer surface 28 of. the head 22 of the hinge post 19, as more clearly shown in Figs. 3 and t of the drawing.

The manner of assembling the device comprising the aforesaid illustrative embodiment of the present invention, and the man ner of operating the same, together with the advantages of the same in operation, will be substantially clear from the foregoing description and may be briefly summarized as follows: After the attaching plates or fins 13 and 1 1 of the bar 12 forming a part of the hinge H have been attached to the

members

10 and 11 of the seat S by any suitable means, as by means of the screws or other suitable fastening devices 15, the hinge posts 19 are applied to the pintles 16 by bringing the sockets 23 of the hinge posts 19 over the respective reduced end portions 18 of the pintles 16. By means of the threaded rods 20 and the associated fastening means such as the nuts and washers or the like, which it is not deemed necessary to show here, the hinge posts 19 carrying the seat S are positioned and fixed in the porcelain of the water-closet or like device.

In operation, it will be noted that the seat S may be rotated into raised position due to the bearing of the pintles 16 in the sockets 28 of the hinge posts 19. The maximum upward swing of the seat S is limited and determined by the angle of the front face of the boss or other raised portion 26. The front face of the reduced end portion 18 of each of the pintles 17 serves as a stop or limit for the angle through which the seat S can be rotated into raised or open position. In the same way, the angle through which the seat S can be rotated into horizontal or closed position is determined by the engagement between the lower face of the boss or projection 26 and the flat face of the reduced end portion 18.

It will be noted that I have provided, in an exceedingly simple and economical. type of construction, a concealed stop hinge which is little liable to get out of order and require repair, which has smooth exterior surfaces and is thus adapted to be readily cleaned, and which prevents the seat from striking the flush tank, the flush pipe, the flush Valve, and the wall or other object adj acent to which the seat may be mounted.

It will be noted that all ofthese desirable results are accomplished without the ezn ployment of any external or visible attaching means which are crunbersome, which render such hinges as? ordinarily made expensive to manufacture and diilicul t to at tach, and which are very liable to get out of order and to require repair and replacement. The hinges formerly made for the same purpose are difficult to clean and to keep clean and generally present an unattractive appearance quite different from the neat and attractive appearance presented by the aforesaid illustrative embodin'ient of the present invention.

Turning now to the illustrative embodiment of the present invention shown in Figs. 5, 6, 7, 8, 9 and 10 of the drawing, S designates the water-closet seat which is in this case of the one-piece type of construction. Suitably attached to the seat S, as by means of the threaded bolts 30 more clearly shown in Fig. of the drawing, are a plurality of pintle posts 31 each consisting of the head portion or knob 32 and the pintles 33 extending transversely of the knob or head portion 32 of the pintle post 31.

Each pintle 33, like the pintle 16 of the embodiment ofthe present invention described in the earlier portion of this specification, is of substantially circular cross section adjacent its inner end 34, where it joins the knob or head portion 32- of the pintle post 31, and has a reduced end portion 35 which is preferably of semi-circular cross section.

Cooperating with the pintles 33 are a plurality of hinge posts 36 having the threaded rods 37 adapted to pass'through the porcelain of the bowl and to be held in position in the bowl by any suitable fastening means, such as nuts and washers, or the like, not here deemed necessaryto. be shown, in the manner well known to those skilled in the art to which the present invention relates.

The upper portion of each hinge post 36 comprises a flange 38 and a head 39 provided with the transverse socket 40. The socket l0 contains concealed therein means cooperating with the pintles or other equivalent remaining portions of the hinge structure for limiting the angle through which the seat can be turned in either direction, up or down, corresponding to the horizontal and raised portions of the water-closet seat, respectively. For this purpose the socket 40 is of substantially circular cross section adjacent the outer portion ll thereof, corresponding to the substantially circular cross section of the pintles 33 adjacent the inner end 34 thereof. 7 Adjacent its inner end 42, the socket 40 is of reduced cross section, as in the form of a reentrant angle. For this purpose the socket 40 is provided with a boss or projection 43 extending from the base 44 part way towards the outer surface 45 of the head 39 of the hinge post 36, as more clearly shown in Figs. 9 and of the drawing.

The manner of assembling the device comprising the aforesaid illustrative embodiment of the present invention, and the manner of operating the same, together with the advantages of the same in operation, will be substantially clear from the foregoing description and may be briefly summarized as follows: The pintle posts are first attached in suitable positions to the seat S by any suitable fastening means, as by means of the threaded posts 31. The sockets 40 of the hinge posts 36 are now applied over the reduced end portions of the pintles 33, in a manner that will be clear to those skilled in the art to which the present invention relates. The threaded posts 37 are now applied to the porcelain of the bowl andare held in position therein by any suitable fastening means, such as nuts and washers, or the like, not here deemed necessary to be shown.-

In the operation of the aforesaid illustrative embodiment of the present invention, the seat S may be rotated into raised or upward position by means of the pintles 33 bearing within the sockets of the hinge posts 36. The angle through which the seat S may be rotated into raised or upward position is limited and determined by the engagement of the flat face of the reduced end portion 35 of the pintle 33 with the inclined front face of the boss or projection 43 within the socket 40. Similarly, the angle through which the seat S can be rotated into horizontal or closed position will be limited and determined by the engagement of the flat face of the reduced end portion 35 of the pintle 33 with the lower or horizontal face of the boss or projection 43 of the socket 40.

It will be noted that in this way I provide a concealed stop hinge for the seats of waterclosets and the like which possesses all of the advantages numerated above in connection with the illustrative embodiment of the present invention described in the earlier portions of this specification, and which possesses none of the disadvantages inherent in the devices employed or suggested for use, as constructed in accordance with the methods hitherto employed in the prior art. The device is exceedingly simple and cheap in construction, is little liable to get out of order and require repair or replacement, has a smooth exterior surface and is thus adapted to be readily cleaned, and is so arranged as to prevent the seat from striking the flush tank, the flush pipe, the flush valve or the wall or other object adjacent to which the seat may be mounted. At the same time I provide concealed means for limiting the rotation of the seat in either direction, upward or downward, while avoiding the disadvantages inherent in the stops for hinges hitherto employed or suggested for use in connection with the seats of water-closets and the like.

WVhat I claim is:

1. In a concealed stop hinge for the seats of water-closets and the like, a pintle having a substantially circular bearing surface and a reduced end portion of substantially semicircular cross-section.

2. In a concealed stop hinge for the seats of water-closets and the like, a cross bar having at each end thereof a bearing pintle of substantially circular cross-section having a reduced end portion of substantially semi-circular cross-section. I
