SGING AND SLIDING DOOR.

Application filed September 21, 1922. Serial No. 589,620.

T 0 all whom it may concern:

Be it known that I, FRANK B. TOWNSEND, a citizen of the United States, residin at Penn Yan, in the county of Yates and tate of New York, have invented new and useful Improvements in Swinging and Sliding Doors, of which the following is a specification.

This invention relates to doors for garages, warehouses and the like, and has for its object the provision of novel combined swinging and sliding doors so constructed that when the opening or closing movement is partly completed, the doors will be positively moved into the fully open or closed position, the doors when open lying at right angles against the jambs, and when closed abutting the j ambs and each other.

An important object is the provision of a door mounting of this character in which the doors are suspended from their centers so that sagging will be impossible even after long continued use. i

A further object is the provision of a door construction in which the doors may be held closed by a singlebolt or lock, and in which little effort is required to effect closing or opening, the mounting being such that the doors will withstand high winds.

An additional object is the provision of a door construction which will be comparatively simple and inexpensive to manufacture and install, highly efficient in use, durable in service, and ageneral improvement in the art.

To the attainment of the foregoing objec'ts and advantages the invention consists in the details of construction and-arrangernent to be hereinafter described and claimed and illustrated in the drawings, though it should be understood that the presentfform.

is merely an exemplification of a preferred embodiment, and that various changes and modifications may be resorted to as may be found advantageous in increasing the adapt- Figure 2 is a similar view looking at the inside;

Figure 8 is a front View similar to Fig. 2, but disclosing a modification of the lower slidable connection between each door and the sill;

Figure 9 is a cross section, on an enlarged scale, showing the said lower connection;

' Figure 10 is a detail View of one of the elements of said lower connection.

Referring more particularly to the drawings, the letter A designates 'the side of a building such as a garage or the like, having a door openin within which is mounted a door frame including uprights C, connected by a lintel D, and a sill E. The under edge of the lintel is flush, while the confronting edges of the uprights are rabbeted or otherwise formed to provide abutments F.

The doors are designated by the numerals 10 and 11, and these doors are of such width that when brought into edge to edge relation, they will abut each other and also against the upright sides of the door frame. as shown, the abutments F serving in a measure to exclude water and wind. The

'abutting edges of the doors are likewise rabbeted, as shown at 12, to effect interfitting relation when closed (Fig. 6). Both doors are provided at their adjacent edges with handles 12 'and the door 10 carries a suitable locking device 13, having a bolt 14 engaging within a suitable keeper in the ad j acent jamb or upright. The lock mechanism is not shown in detail, as it is not important though its position is indicated in Figure 1. This locking mechanism is preferably provided with a latch bolt 15 operated by knobs 16. The construction of these elements is old and well known.

The mounting for the doors consists of a pair of spaced tracks 17 carried by brackets 18 suitably mounted on the inside of the building above the door frame. Supported sisting of a frame 19, having a grooved wheel 20 journaled therein and rolhng upon the track. Depending from the frames 19, are rods 21 which: are revolubly mountedwithin U-shaped brackets 22 secured upon the inner facesof the doors. The lower ends of the doors are equipped with similar brackets 23, through which are journaled rods 24,

which pass through bearing plates, 25, slidable through guides 26 mounted onthe sill. By this construction it will be seen that each door is pivotally supported at its longitudinal axis so that it may swing during opening and closin movement.

Secured against t e inside of the building above the upper corners of the door frame are guide sheaves 27 through which are trained chains or other flexible members 28, which are connected with the adjacent hanger frames 19, and which are also connected with springs 29, as shown, or with weights which may be substituted for the springs. Weights are not illustrated as they are the mechanical equivalents of the springs. Secured against the inside of the building near the lower corners of the frame, are other guide sheaves 30, through which are-trained chains or other flexible members 31, which are connected with the lower ends of the rods 24, below the guide plates 25, by means of suitable links 32, it being -noted that the sill is grooved, as at 33, for the accommodation of the chains (Fig. 7). After passing through the sheaves 30, the chains 31 are trained through other sheaves 34 which are located below the sheaves 27, and these chains are then connected with the springs 29.

Secured at the confronting edges of the door frame and extending into the building are resilient strips 35, which not only act as buffers for the doors when they move to open position, but which also act as fulcrums against which the doors engage and slide during the closing movement thereof.

Assuming that the doors are closed, as shown in Figures 1 and 2, in order to effect opening thereof, the lock must be operated with whatever key is provided to unlock the doors, and the knob 16 is turned to re lease the latch, after which, still holding the outside knob 16 in his left hand, the operator grasps the handle 12 of the door 10 and pushes the left hand edge of the door to the inside of the building. After the door has been thus partly opened, the spring 29 associated therewith pulling upon the carriage at the top of the door and the guide plate 25 at the bottom thereof, will complete the movement, so that the door will be drawn forcibly against the edge of the left hand upright of the frame, coining in contact with the strip 35. The opening movement is illustrated in Figure 6.

. spring associated with the door pulling'upon the carriage and guide plate at the top and bottom of the door, respectively, will pull the door against the frame. The fully open position of. both doors is shown in Figures 3 and 4, and it will .be observed that they lie closely against the'frame, and that they will not be shaken or swung even by -a high wind. As the doors open, it is of course obvious that the hangers slide toward the outer ends of the tracks, 17, and that the guide plates 25 slide within their confining brackets 26, so that there will be smoothness and evennes of movement.

"To effect closing, the reverse operation is followed, the door 11 being closed first and the door 10 last. .When either door is swun from the open to the closed position, it will first bear against the 'free ends of the resilient strips 35, which act as a" fulcrum and against which the door bears throughout its closing movement. While the doors are being closed, the springs 29 oppose their movement, as the wheeled carriages 18 and guide plates 25 slide toward the center of the door frame and place the springs under tension. However, when the closing movement has been completed, the springs operate'to force the outer edges of the; doors against the jambs, so that a tight fit will be insured and rattling in a wind storm prevented. It might be mentioned, in passing, that the inside of the lintel carries a depending strip 36, against which the upper edges of both doors abut when in closed position, and the upper edges of the doors themselves carry similar abutment strips 37 which engage the rear side of the lintel.

Figs-8, 9 and 10, I have disclosed a modified form of the invention. consisting of a different connecting means between the rods o-r bolts 24 and the sill of the door frame. I have applied to the parts the same numerals as employed in the description of the first form of the invention where the parts are the same, and the description already given will apply to the modified construction with this exception. In Figs. 8, 9 and 10, the rods 24 are provided with a reduced and, threaded terminal passed through an opening 24- of an angular plate 25% a nut at the other end the plate is bent in reverse directions-25", extending up and down so as to form lugs to fit within and he guided 1n its movement by the guide 26, which is wea ons mounted at one side of the sill E. These figures represent the preferred form of construction for the lower guiding connection between the door and the sill.

From the foregoing description and a study of the drawings, it will be apparent that l have thus provided-a simply constructed and easily installed swinging and sliding door structure, in which the arrangenunt is such that the opening movement is assisted by springs or weights, the spring or weight means furthermore operating to hold the doors firmly against their jillllbS when in closed position. Owing to the fact that. the doors are pivotally mounted at their longitudinal centers, they cannot sag even after long-continued use and in this way durability is insured. As the doors are suspendcd by wheeled carriages traveling upon tracks, and as their lower ends are guided by the slidably mounted guide plates, it is apparent that the movement of the doors from open to closed position, or vice versa, will be smooth and easy, binding being prevented by the peculiar cooperation of the parts. A noticeable feature of advantage is that rain and wind will be excluded, as the edges of the doors have interfitting engagement, and as the jambs or sides of the frame are rabbetcd to receive the outer edges, together with the fact that the abutment strips are provided at the lintel and upper edges of the doors. Owing to the simplicity of the construction, it is evident that there is nothing to get out of order so that the mechanism should have a long life and satisfactorily perform all its functions.

\Vhile I have shown my invention applied to a double door, the invention may be carried out in a single door.
