DOOR-GUIDING DEVICE.

Specification of Letters Patent.

Patented Nov. 17, 1914:.

Application led December 9, 1912. Serial No. 735,686.

This invention relates to a locking de-V vice for doors and thelike and is designed more particularly for use in connection with doors of street cars, in which the free edges of the doors move in a line parallel or substantially parallel with the doorway, to hold the edges of the door against lateral displacement.

The object of the invention is to provide a locking device of this character which will be of sucha construction and so arranged that it will offer no obstruction to the passage of persons through the doorway and will not be liable to catch the clothing of such persons; which will be of such a con struction as to cause the door to accurately close; and which will edectually .prevent the lateral displacement and rattling of the door.

In the accompanying drawings, Figure l is a transverse section of the forward portion of a street car showing the platform in plan view with my invention applied thereto; and Fig. 2 is a perspective view of the invention showing one of the doors partly open.

In these drawings I have illustrated one embodiment of the invention and have shown the same applied to a street car having both the entrance and exit passageways at the forward end of the car, as fully shown and described in my pending applica- 'l tion for patent on passenger car, filed July l5, 1911. Ser. No. 638,635, but it will be nnderstood that this particular car and this particular type of door are used for the purpose of illustration only and that the invention is applicable to doors of various kinds and that the doors may be arranged in variousparts of the car or other structure.

The front platform of the car as here illustrated is indicated at l and is provided at its right hand side with a doorway divided into two passageways 2 and 3, respectively, by means of a barrier having a vertical portion 4 arranged at the doorway and constituting a post which divides the doorway into two passageways. These two passageways are controlled by separate doors 5 and 6 and, in the present instance.,`

these doors are folding doors of the well known doubledoor type. A door of this type comprises two sections hinged together at their adjacent edges, the outer edge of one section of the door being pivotally mounted at the adjacent edge of the doorway and the outer edge of the other section of the doorway being guided in such a man` ner that it will move in a fixed path when the door is opened or closed. Preferably, the manipulation ofthe door is accomplished by rigidly securing the edge of the one section to a vertical shaft 7 mounted at the edge of the doorway and having a crank arm 8 connected to a rod 9 which may be manipulated by the motorman or other oilicial on the car. Vhen the shaft 7 is rotated the section of the door which is rigidly secured thereto will be moved outward and inasmuch as the inner section is hinged to the outer section and has its free edge guided in a fixed path it will be obvious that the inner section will be folded upon the outer section and both will be moved to one side of the doorway. This construction is a well known one and need not be here shown or described in detail.

Inasmuch as each door is controlled from its outer or hinged edge and the guide for the inner edge thereof is at the top of the door, where it will be out of the way of persons passing through the doorway it is desirable that some means should be pro` vided for locking the inner edge of the door, and particularly the lower portion thereof, in its closed position. Further, it is desirable that this means should be such as to cause the lower edge of the door to move accurately into its closed position, thus preventing the coperatiiig locking parts from coming into abnormal engagement and preventing the proper closing of the door. To accomplish this result I haveprovided each of the double folding doors 5 and 6 with a bracket 10 which, in the present instance, is in the form of a socket rigidly secured to the inner side of the door near the bottom thereof and having one wall, 11, arranged at an angle to the door and to the path in which'the inner edge of the door moves. Iigidly secured to a part other than the door and supported in the path in which the bracket will travel when `the door is moved to its closed position is a block l12 having one edge arranged at an angle to the line of movement ofthe edge of the door and adapted to engage the bracket and coperate therewith to move the door into its closed position and hold the same against lateral displacement.

In the present arrangement of they parts the` socket and the block are both tapered. A. single block is preferably employed for both doors and this block is here shown as substantially oval in shape and as forming the base for the post or vertical member 4 of the barrier to which it is rigidly secured. 'Ihe opposite end portions of this block converge away from the post to impart the proper angle to the inner 'edges thereof which coperate with the inner walls of the brackets l0. It will be apparent, therefore, that when one of the doors is moved toward its closed position the tapered end of the corresponding block will enter the wide end of the socket. rIhe width of the open end of the socket-or bracket is such that iio ordinary displacement of the lower edge of the door will prevent the end of the block from entering the socket. The furthermovement of the door toward its closed position will cause the coperating surfaces of this block and the socket to force the door into its proper closed position and these parts will hold the door against lateral displacement and will prevent the'same from rattling. Further, the block is arranged in such a position and is of such a size and shape that there is little or no possibility of its oifering an obstruction over which a person pass-l ing through the doorway might trip or of its catching the clothes of persons passing through the doorway. Further, it is of a simple, inexpensive construction and is very strong.

Vl/Yhile I have shown and described one embodiment of my invention it will be understood that this has been chosen for the Y 4sition..

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. The combination, with a structure havl 'ing a floor, a doorway at one edge of said floor and a door for said doorway, of'a door-guiding device comprising a tapered block rigidly secured to said-floor near the.

edge of said door, when the latter is in its closed position, and having a smooth exterior surface without projecting parts, and a recessed bracket carried by said door and arranged near the edge thereof to engagek said block when said door is moved to its closed position, said bracket having one wall arranged obliquely to the line of movement of said door to engage the tapered surface of said block and draw said door snugly to its closed position and retain it in said position.-

2. The combination with a structure having a door, a doorway near one edge of said floor, and a door for saiddoorway,

comprising two members adapted to fold one upon the other when the dooris moved to its open position, of a guiding device for said door comprisingv a block rigidly secured to said floor near the edge of said 1 door, when the latter is in its closed position, and a bracket secured to that side thereof which is folded inward when the door is in its open position, said bracket bein0F ada ated to enafre said block when C C C said door is moved to lits closed position.

3. The combination with a structure having a floor, a doorway, a post'to divide said doorway into two passages, and a door to close each of said passages, each of said' doors, having its free edge movable toward andaway from said post, of a tapered block secured to said floor at the base of said post, brackets carried by the respective doors and said block when said doors are moved toward their closed positions.
