DOORBOLT.

Application filed April 5, 1922. Serial No. 549,797.

To all whom itmay concern Be it known that I, ELLIS a citizen of the United States, and a resident of Aurora, in the county of. Kane and State of Illinois, have invented certain new and useful Improvements in Doorbolts, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in door bolts and particularly to bolts used as a part of the locking mechanism employed for securing in closed position the hinged doors that serve as closures for large doorways, such mechanism comprising two bolts extending, respectively, upwardly and downwardly from a common actuating member, one of such 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 in the floor. As

the height of these doors is often very considerable it is deemed desirable to form each of the bolts of a plurality of sections secured end to end because so constructing them better adapts them both for storage and shipment. It is the object of my invention to so construct the sections that together form one of such bolts that ,they can be united end to end very quickly and easily, and to provide also in connection with each two such sections a device adapted for attachment to the door that carries the locking mechanism that will perform the several functions of preventing the joined sections from becoming disengaged from each other, of serving as a guide for the bolt as a whole as it is moved longitudinally into and out of locking position, and of efl'ectually concealing from view at all times the joint between connected sections whereby the bolt presents the appearance when in place of a continuous bar. Briefly stated, I accomplish this object-in the preferred embodiment of my invention by constructing adjoining bolt sections with end portions of reduced size to one of which is secured a stud and in the other of which is a hole adapted to receive the stud, thereduction in size of these end portions being approximately the same, sothat the main or body portions of the sections will be in substantial alinement and thereby preserve the appearance, when the joint is covered, of a bolt made of a continuous piece of material,

ed to be simultaneously projected or retracted, myiimprovements being embodied in connection with each of the bolts;

Fig. 2 is an enlarged detail, being a front view of the joined end portions of two bolt sections, the clip that covers such portions and acts both as a guide for the bolt and as a means for preventing the sections from becoming disengaged from each other being shown partly in section and partly broken away;

Figs. 3 and 4.- are horizontal and vertical sections taken respectively on the lines 3--3 and 4-4 of Fig. 9;; and

Fig. 5 is adetail, artly broken away, of the lower section of the upper one of the bolts shown in Fig. l, or it may be considered as representing the intermediate section that would be employed if either of the bolts shown in Fig. 1v comprised three sections instead of only two as shown.

Referring to the several figures of the drawing,-A, B indicate two ordinary hingeddoors that together are adapted to close a large doorway. To the inner face of oneof the doors,-A in the construction illustrated--is attached a locking mechanism near the free edge of the door, such mechanism comprising upper and lower bolts each of which, in the construction shown, is

formed of two alined sections, the upper and lower sections of the upper bolt being indicated by C and C respectively, 'while the upper and lower sections of the lower bolt are indicated respectively by D and D. Each of the inner sections of each bolt is secured 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 enclosed in a casing G, which plate is adlafted to be turned by means of a handle that is connected with the said rotatable plate through a shaft that projects through the casing. Each bolt' in the construction shown passes loosely through a guide near the upper and lower parts of the door A, and which are secured to such door as usual, the guides referred to being indicated respectively by I and J. Locking mechanisms of this general type are common and well understood, and need no further description, and furthermore my invention, relating to the bolt itself as it does, is not confined to use with such a construction as here illustrated and above briefly described, although its greatest usefulness will probably be found to exist when embodied in a locking structure of this general, type. Each of the bolts when in locking position projects into a keeper, the upper keeper being connected with the upper cross-bar of the doorway frame and the lower keeper being set into the floor. The lower keeper, that is shown in Fig. 1 and indicated byK, is an adjustable one, and forms the subject matter of a separate application heretofore filed by me as Serial No. 541,640. Any other suitable keeper than that shown may of course be employed.

My present invention has more particularly to do with the construction of the locking bolts themselves. Each bolt comprises a plurality of sections which may be of any desired number, and which number may well vary according to the height of the door to which the bolts are attached. In its simplest form two bolt sections, are con nected together as shown in the drawin As here shown, the bolt sections are pre? erably formed of rods that are round in cross-section throughout their length, except at their adjacent end portions, and the se end portions are forged or otherwise formed to provide two approximatelysimilar heads of reduced diameter in one direction, each of which has, preferably, a flat face, as best shown in Fig. 3, which two facesare adapted to lie in contact with each other. One of these heads is indicated by 10 and the other by 11, and in one of themthe one here indicated by 10-is suitably secured a stud 12 that projects some considerable distance beyond the flat face of said head. Formed in the other head 11 is a hole 13 of a size and shape to freely-- course, provided neither section is allowed to move laterally, and to prevent their disengagement by such a movement, I provide a clip 14 that lies over the connected together end portions of the bolt, the turned ends of such clip lying against the surface of the door and being attached thereto by screws "15 as shown. The outer surfaces of the heads 10 and 11 are preferably left rounded as shown. and the clip approximately conforms to such surfaces, and while fitting reasonably snugly to them will yet permit the bolt to be moved freely up and down therein. This clip, therefore, serves as a guide in addition to the ordinary guide such as I or J, and by reason of the character of its fit around the bolt sections it will, as will be understood, effectually hold the two bol t sections interlocked one with the other, and thereby permit the bolt as a whole to be moved longitudinally as freely and to the same extent as if such bolt were made of a single piece of material. In addition to its function of acting as a guide and as a means for holding the said heads of the sections in interlocked relation, this clip serves to effectually cover said heads at all times, inasmuch as it is made long enough so that it will not allow the heads or any portions thereof to be disclosed to view by reason of the bolt being either projected or retracted to the limit of its movement, which is a desirable feature of construction.

In Fig. 5 I have shown two end portions of a single bolt section as it would be made when such section forms an intermediate member of a bolt comprising three or four sections. When made of two sections, however, it -is only necessary, for the embodiment of my invention, that the adjacent ends thereof be made soas to interlock in the manner described, although when made of only two sections, as here illustrated, the inner section of each bolt may have its ends made as shown in Fig. 5, so that the stud on the inner end of such section may. be inserted into a hole in the adjacent operating link and be there secured in any desire manner.

What I claim as m invention and desire to secure by Letters atent, is-

l. The combination with a locking-bolt comprising two alined sections having their adjacent end portions connected together,

of a clip adapted to be secured to a door,

said clip fitting over said end portions and serving as a guide for the bolt and also as a means for maintaining the alinement of said sections. v

2. A locking-bolt comprising in combination two alined sections, the adjacent end portions of which are reduced in size rela-' tively to the main or body portions of the sections, such reduced end portions overlapping and interlocking, and a clip extending over said end portions and adapted to be secured to a door and serve as a guide for the bolt and as a means for maintaining the alinement, of said sections.

3. The combination with a locking-bolt comprising two alined sections having their adjacent end portions overlapping, a stud connecting said overlapped end portions together, and a clip extending over said end portions and adapted when attached to a door to prevent their se aration, said clip also serving as a guide or the bolt.

4. The combination with a locking-bolt comprising two alined sections having their adjacent end portions overlapping, a stud loosely connecting said overlapped end portions, and a clip adapted to be attached to a door and extending over said two end portions to serve as a guide for the bolt and preventing the said sections thereof from becoming disconnected, said clip being of a length to maintain said sections in alinement by preventing relative turning thereof on said stud in either the projected or retracted position of the bolt.

5. A locking-bolt comprising in combination two alined sections, the adjacent end portions of which are in overlapping relation, a stud securing such end portions together, and a clip extendin over said connected end portions and a apted to be secured to a door, said clip serving as a guiding device for the bolt and also as a means for preventing disconnection of the sections and extending len hwise of-the bolt sufficiently to conceal t e joint between the sections in either the projected or retracted positions of the bolt.

6. A locking-bolt comprising in combination two alined sections, the adjacent end portions of which are of reduced size and in overlapping relation, one of which end portions has a stud secured thereto and the other one of which has a hole therein into which said stud projects, and a clip extending over said connected end portions and adapted to be secured to a door, said cli serving as a guiding device for the bolt and also as a means for preventing disconnection of the sections thereof and extending lengthwise of the bolt sufliciently to conceal the joint between the sections in either the projected or retracted positions of the bolt.
