TEICH, F NEW BRITAIN, CONNECTCT, ASSIGNOR TO THE AMERICAN l HARDWARE CORPORATION, 0F NEVI BRITAEN, CONNECTICUT, A CORPORATION OF CONNECTICUT DOOR STOP AND HOLDER Application filed December 4, 1931. Serial No. 578,969.

lThe present invention relates to lan improved door stop yand holder of the type which are anchored into theA masonry of the floor. Such door stops and holders ordinarily coinprise a casing of iron or the like which is anchored into the floor and which contains a casing with a heavy spring and ball or the like carried thereby, part of the ball extending through a cover plate for yielding en- 0 .gagement with the under surface of the door the cover plate having a horizontally extending raised portion or stop for engagement with the side of the door.

A major disadvantage of this type of door stop and holder has been that the stop; being positioned at the time that the floors are being laid and before the door with which 1t cooperates is hung, is frequently found to have its horizontal projection improperly aligned with respect to the side ofthe door when open, with the result that the door stop functions improperly or not at all, or the floor has to be torn up and the door stop repositioned. The present invention provides 5 a means in door stops of the general type described for permitting ready adjustment of the cover plate afterI installation of the stop whereby alignment of the horizontal proj ection on the cover with the side of the door may be eected at any time.

rIn Ythe accompanying drawing the preferred embodiment of the invention is illustrated.- f

The improved door stop and holder includes a cylindrical receptacle 1 of cast iron or the like which is anchored into the masonry 2 of the oor so as to have its upper edge flush' with the floor surface; the upper portion of the receptacle 1 being of a relatively larger diameter .than is the lower portion,

and its inner cylindrical surface being slightly under-cut as shown. A circular cover plate 3 of a diameter at least as great as the outer diameter of the upper portion of re-l ceptacle 1 and preferably greater, as shown, is symmetrically positioned over the receptacle but is not secured thereto. Secured to the under side of the cover plate 3 by screws 4 is a cylindrical casing 5 which has an outside diameter'less than the inner diameter of the lower part of the receptacle and a depth less than that of the interior of the receptacle so as to be centrally suspended therein. AV heavy coiled spring 6 within casing 5 carries a support 7 for a ball 8 the upper portion of which extends through a central circular opening in the cover plate 3; the ball being forced upwardly by the spring 6 for yielding engagement with a suitably shaped plate 9 carried by the door 10 in the usual manner. Cover plate 3 has the usual horizontal ridge 11 thereupon for engagement with the side of the door 10 when the casing 5 and the inner under-cut wall of the enlarged upper portion of receptacle 1. A single turn 14 of a relatively powerful coiled spring is located in a circumferential groove 15 in the ring portions 12 and 12 and tends to hold the portions 12 and 12 together with their inner surfaces flush with the outer surface of casing 5 and out of engagement with receptacle 1; the thickness of the ring being slightly less than the width of the annular chamber 13. The ring portions 12 and 12? are forced apart in opposition to the spring 14 by a pair of wedge shaped members 16 and 16 which are internally threaded and are located beneath the two junctions of the ring portions 12 and 12. Screws 17 and 17 passing through the cover plate 3 and through suitable vertical grooves in the ring portions at their junctions are screwed into the wedge members 16 and 16 respectively so as to cause the ring portions tovbe forced apart (as shown best in Fig. l) when the wedge members 16 and 16 are raised by tightening of the screws 17 and 17 The lower edges of the ring portions 12 and 12 are cut away to fit the upper ends of the wedge members 16 and 16` to prevent turning thereof with the screws 17 and 17. rlhus, when screws 17 and 17 are turned so as to lower wedges 16 and 16 into position where the spring 14 holds the adjoining edges of portions 12 and 12 in contact, the cover plate 3 may be turned to position ridge 11 or, if desired, the plate 3 and portions carried thereby may be lifted from receptacle 1. When, however, screws 17 and 17 are turned to raise wedge members 16 and 16into the position shown in the drawing, plate 3 cannot be turned nor can it be lifted from the lreceptacle because of the frictional grip between ring portions 12 and 12 andthe inner under-cut wall of receptacle 1 against which the ring is forced by the wedge members 16 and 16. The cooperation between the split ring 12-12, the spring 14, wedge members 16 and 16 and screws 17 and 17 K thus provide a ready means for angular adjustment of the door stop while insuring rigidity of the parts when in use.

To install the device the box `or receptacle 1 is set into the Hoor with its upper edge flush with the surface of the floor. The receptacle is preferably of cement 'box form as shown so that in the case of cement floors it may be securely anchored in the cement. The cover plate need not be applied until the door is hung so that the plate, which is usually of polished brass, andthe attached parts are not subjected to injury during the completion ofy the building. When the door has been hung and the cover plate applied, the latter may be easily adjusted so as to lproperly position the elongated stop member thereon with relation to the side of the door.

As will be evident to those skilled in the art, my invention permits various modifica,- tions without departing from 'the spirit thereof or the scope of the appended claims.
