Application October 28, 1944, Serial No. 560,839

My invention relates to fittings for closet bowls and more particularly to the collars used in connectingv the base of the bowl to the waste pipe bend. 1

In installations of the above character, the securing bolts are applied with heads under the ange of the bend collar rising upwardly through the bowl base to receive cap nuts while the floor under the said flange usually lacks sulicient friction for the head of the bolt to keep the latter from turning as the cap nut is applied. Many times this does not occur, and the bolt keeps on turning with the nut and'making the task difficut and slow.

It is therefore one object of the present invention to modify the collar in a manner to lock the bolt after it has been applied, so that it may not turn as the nut is mounted and screwed down.

A further object of the invention is to modify the collar in a manner to permit the standard bolt to be used, so that no special provision need be made or parts secured for that purpose.

Another object of the invention is to construct the collar along lines of extreme simplicity and without the addition of any parts* thereto for the accomplishment of the present purpose.

An important object of the invention is to provide an improved collar whose cost will only slightly exceed that of the conventional collar.

With the above objects in view and any others which may suggest themselves from the description to follow, a better understanding of the invention may be had by reference to the accompanying drawing, in which- Fig. 1 is a side elevation of a conventional closet bowl installation, showing its base connections in section;

Fig. 2 is a top plan view on an enlarged scale of the improved collar;

Figl 3 is a similar fragmental view on a further enlarged scale showing the manner in which the attaching bolt is locked; and

Figs. 4 and 5 are, respectively, sections on the lines 4 4 and 5-5 of Fig. 3.

1 claim. (cl. 28s-34) Referring specifically to the drawing, the closet A s was previously mentioned, a slight amount 2 of clearance is usually present in the iioor below the collar iiange I3 in order that the headsfof the bolts may find room under the flange. The bolt under consideration is indicated at I8, and its head I0 is in the nature of a thin, elongated plate, preferably rounded at the ends as indicated at 20. In the novel embodiment, I do not apply the head of the bolt beneath the collar flange I3, but lower the bolt head directly into an opening vZI in the top face of the side flange. As indicated more clearly in Fig. 3, the opening referred to is similar in form and somewhat larger than the head I9 of' the bolt. Also, the opening is extended on opposite sides with a pair of lateral cavities 22 whose outer limits or side walls are sufciently spaced to permit the bolt to be turned crosswise and with the end portions of its head I9 lodged in the cavities 22 as indicated by dotted lines in Fig. 3. As seen in this figure, the clockwise turning of the boltthat is, in the same direction as the cap nut 23 applicable above would be turned-locates its head I9 crosswise of the opening 2I and in this position the end portions of the head are designed to meet end walls 24 of the cavities 22.

It will be evident from the above explanation that when the head of the bolt I8 has once assumed the position just described, it is locked both from being raised out of the opening 2I as well as from turning any further. Thus, when the cap nut 23 is applied and screwed down, the bolt will not turn beyond the position mentioned and remain still while the cap nut is being turned. Since the regular thickness of the collarange I3 will be insuiiicient to accommodate the cavities 2l and leave enough top and bottom 4stock in the ange, the latter is thickened downwardly as indicated at 25 in the region of the cavities 22. Fig. 5 shows this feature more clearly, and the same will either find the necessary clearance in the floor I 6 or require very little work to produce the same.

It will be evident from the above description that I have improved the closet bend collar in a manner toellminate the application of the bolt or any other fastening means underneath the ange I3, that is, any place where it is diicult or not feasible to keep the head of the bolt from turning. On the other hand, the bolt is now entirely within and above the collar flange, and its application is in the open by simply lowering the bolt with its head in the opening 2| and giving the bolt a quarter-turn. to lock it as described. The closet bowl base may now be lowered to receive the bolt and permit the application and quick fastening of the cap nut 23. An improvement is thus had which makes no alteration in the bolt, and only requires the collar to be cast with a special core, occasioning but a slight extra expense in its manufacture when this is done on a production basis. The collar therefore remains in a single piece, and no extra part is added to the installation for the purpose of the present invention. The improvement thus makes the application of the bolt and itslfastening a simple and quick operation.

While I have described the invention along` specic lines, various minor changes or renements may be made therein Without departing from its principle, and I desire to consider such changes and refinements as coming Within the scope and spirit of the appended clairrnwV` I claim: q
