COMBINED DOORSTOP AND KEEPER PLATE.

Application filed March 7, 1922. Serial No. 541,640.

T0 @ZZ whom t may concern.'

Be it known that I, ELLIS J. G. PHILLIPS, a citizen of the United States, and a resident oi" Aurora, in the county of Kane and State of Illinois, havel invented certain new and useful Improvements in Combined Doorstops and Keeper Plates, of which the fol* lowing is a specification, reference being had to the accompanying drawings.

It is commonto provide certain hinged doors that are used tor closing large doorways with a locking mechanism that com prises two bolts extending, respectively, upwardly and downwardly from a common actuating member, one ot said bolts being adapted to be projected into a keeper carried by the overhead beam of the doorway frame and the other bolt into a keeper set into the floor. It is usual to so construct the frame of the doorway that a positive stop is provided for the upper edge portion of the face of the door to strike against when the door is brought to its fully closed position, and the striking ot that upper part of the door against such iixed stop ensures the upper locking bolt being brought directly opposite the socket or keeper that is provided to receive it. There is ordinarily no stop pr0- vided for the lower edge portion of the door to strike against and it is, therefore, frequently the case that more or less ditlicultyy is experienced in bringing the lower locking bolt into the required alinement with the floor socket or keeper, such diiliculty being :frequently increased becausefof the door having become somewhat warped.

It is an object of my invention to provide a device for attachment to the floor of a building which will serve both as a stop for the lower edge portion of a door and as a keeper :for the lower locking bolt that the door is provided with. Inasmuch as the doors vary in thickness it is evident that if the distance between the stop that the face of the door comes in contact with and the `socket that such bolt enters was not capable of being varied such combined stop and keeper could only be used in connection with one thickness oi door. To avoid the objection of a dealer having to carry in stock a quantity ot the said devices for doors of .different thicknesses is another object oi' the; invention, and broadly stated, I accomplish constitutes the door stop, such plate beingy adapted to be secured to the base in any of its adjusted positions. A further object of the invention is to render such adjustable keeper-plate adaptable for use in connection with doors of the maximum as well as the minimum standard thicknesses without being obliged to `rely upon moving such plate longitudinally oit the base that it rests upon,

.and this I accomplish by making the opening in such plate, and into which the said locking bolt projects, at unequal distances from its ends, whereby by turning the plate end for end the bolt-receiving opening therein can be positioned for receiving the locking bolt on any standard thickness of door, whereas if such opening kwere midway of the ends ot' the plate the movement of the keeper plate longitudinally of the base would he the only way to eitect the desired adjustment. Furthermore, in view o'l' the quarter-inch dierences in thickness that generally prevails with respect to such doors it would not be feasible to properly arrange the openings in the base that receive the bolts that attach the keeper to the base if successive adjustments were made merely by moving the keeperalong on the base. By my construction, however, each of such openings for the securing bolts is adapted for use when the device is employed in connection with either one ot two thicknesses ot doors.

Referring to the several ligures of the draWing,-A-B indicate tvvo ordinary hinged doors adapted together to close a large doorway. To the inner tace of one of the doors-A in the construction illustratedis attached a locking mechanism near' the free edge of the door, such mechanism comprising upper and lower boltsk C and D, respectively, each of said bolts being secured at its inner end -to a link, Which links are indicated by E and F, respectively. The inner ends of the two links are; pivotally connected to a rotatable plate r enclosed in a casing G which is turned by means oa handle H connected with the l, saidrotatable plate by means of a shaft that projects through the casing. Each bolt passes loosely through a guide near the upper and lower parts of the door, which guides are indicated respectively by I and J. Loc-king mechanisms of this general type are common andV Wellunderstood and need no further description. Each of the bolts when in locking position projects into a keeper, which keepers are respectively connected with the upper cross-bar of the door- Way frame and the floor of the building# such. a cross-bar being here indicated by K and the floor by L.

My invention has particularly to do with the means l*for retaining the lower one ot such bolts, and, as here shown, such means comprises two principal elements, to-Wit, a base and an apertured plate adjustably secured upon suoli base. The' base member is indicated generally' by'y 10, and as here sboivn it isy of oblong shape and provided at onev end with a heavy lip 'l1 that rises above the tace of' the base sui'iiciently to serve as a stop for the door. The base as a Whole is adapted tobe set into a correspondingly-shaped recess in the floor, such recess being indicated by M, and of a depth toI bring the facev of the base substantially flushV with the surface of the door. Asrshown, thelbasef-is provided with a downcent to the upstanding lip 11 as a cross-bar and designate it by the numeral 14, and shall refer to the portion of such Wall at the other end ot' the base as a cross-bar and designate it by the numeral 15. 16 and 17 indicate, respectively, two inwardlyextending ledges at opposite sides of the opening 13, each of said ledges being slightly below the plane of the upper faces of the end cross-bars lll and l5, as clearly shown in Fig. 5. The edge of that portion oi the ledge 16 that lies adjacent to the cross-bar 14C has formed in it semi-circular notches spaced at regular intervals apart and indicated respectively by 16a, 1Gb and 16, and in the edge of that portion oit the ledge 17 adjacent to the end cross-bar 15 is a similar' series oi spaced-apart notches which are indicated, respectively, by 17a, 1Tb and 17C; 18A indicates a platev that is rabbeted at opposite sides in its under face as indicated at 19/ to adapt it to rest upon the ledges 1,6 .and 17, and have its upper tace substantially iush With the upper faces of the

cross-bars

14 and 15 of the base member. This plate 18v has yformed therethrough an opening 2O which is considerably nearer one end of the plate than the other end, and, for convenience of description, I shall refer to the narrower' portion at one end of this plat-e as the end 21, and to the Wider' end portion as the end 22, and so indicate these parts, on the drawing. Adjacent to diagonally-opposite corners the plate 1S is pro-vided with bolt holes 23, 2l, respectively, and when. the plate is in position on the

ledges

16 and 17 with its narrower endv portion 21 opposite the cross-bar lst et the base the bolt hole 23 is adapted toE register with one of the notches in the ledge 1G and at the same time the other bolt hole will register with one of the notches in the other ledge. The plate lis adapted to b-e secured to the base by' means of two screw bolts 25 and nuts 26 (see Fig. 4).

lt is common practice to make doors of the character ivitl'r which myv improvements will be used of standard thicknesses, such thicknesses being' in inches l, 2, 291;, 291;, 22, and 3, and according to the positioning of the keeper plate 1801i the base 1,0 such plate will be adapted 'tol have received in its opening 20 the end of a bolt, such as D, carried by a door of any such thickness. As shown, the base 10 is screwed firmly to the floor at the proper place to bring the upstanding lip 11 in position to have the lower part of the door A abut against it, such fastening of the base in place being, in the construction shown, by screws 27 that pass through holes 28 near opposite ends of the base. Before the base is attached in place, howeverthe keeper plate is to be adjusted with reference thereto and boltedin position, and its position on the

ledges

16 and 17 will be determined by the thickness of the door. If the door is one of minimum thickness the end portion 21 of the keeper plate will abut against the cross-bar 14 and in that position the bolt hole 23 will register with the notch 16a in the ledge 16 and the bolt hole 24 will register with the notch 17aL in the ledge 17. If, however, the door be of the next standard thickness, which is here assumed to be two inches, the position of the keeper plate will be reversed end for end so that its end portion 22 lies against the cross-bar 14 of the base, and when in that position its bolt hole 3 will register with the notch 17a and its bolt hole 24 will register with the notch 16a and by reason of such reversal of the plate the opening 20 therein will be carried just enough farther away from the cross-bar 14 to properly position such hole to receive the locking bolt carried by the two inch door. For the next standard thickness of door, viz, one of 21` inches, the keeper plate will be again positioned with its narrower end portion 21 adjacent to the cross-bar 14 of the base but suiciently removed therefrom to bring its bolt holes 23 and 24 in register with the notches 1bb and 17h, respectively. For

A the next standard thickness ofdoor, namely,

one of 2% inches, the keeper plate would be reversed end for end but its bolt holes would still register with the notches 16b and 17D, but by reason of the greater width of the end portion 22 of the plate its bolt-receiving hole 20 will be carried just enough farther away from the cross-bar member 14 to permit it to be engaged by thefbolt on this thicker door.y The same manner of adjusting the keeper would be followed in adapting it for receiving the locking bolt carried by doors of the next two standard sizesthat is for the 2i inch thickness of door the keeper plate would have its narrower end portion 21 toward the cross-bar 14 of the )ase and for the 3 inch thickness of door would have its wider end portion 22 so located, but in both such adjustments the bolt holes of the keeper late would aline with the notches 16c and 1 C, respectively.

By my invention I provide not only a very effective and securely affixed stop for a door toabut against in its closed position, but 1 provide also in connection therewith a keeper plate that'can be very readily and easily firmly secured to the base plate that carries the stop, and which can be so adjusted along f justability is a matter of great convenience to dealers in'and users of builders hardware, for with the dealer it obviates the necessity of carrying in stock a comparatively large quantity of devices, and with builders it obviates the necessity of having to specify with eXactness the number of such articles as may be required in connection with a job having a large number of such doors, which doors indifferent situations on the same job may be of dilerent thicknesses. It is also of very considerable advantage to so construct the keeper plate that the portion at one side of the bolt-receiving opening is of a dierent width from that at the other side, because the base can be made somewhat shorter than if the keeper plate were merely slid along a quarter of an inch each time an adjustment for a next greater thickness of door must be made, and, furthermore, such an adjustment of a quarter of an inch at a. time would be so small as to preclude the proper spacing apart of notches for the reception of the securing bolts that hold the plate to the base. Of course, it is to be understood that the widths of the

portions

21 and 22 will be properly related to each other so that a reversal of the keeper plate end for end will secure the desired quarterinch shifting of the bolt receiving hole 20. This will be secured by providing that the holes 23 and 24 will be so related in position to the large opening 2O that the dilference between the distance from a line drawn across the plate 18 through the center of such opening 2O to a parallel line drawn through the center of the hole 23 must vary from the distance between the center of such opening 2O and a corresponding line drawn through the center of the hole 24 to the same extent, or in the same amount, as the variation of they steps of the adjustments that are to be provided for.
