BRACKET FOR sLinlNo DooRs.
SPECIFICATION forming part of Letters Patent No. 705,081, dated July 22, 1902. pplication filed October 14,1901. Serial No. 78,572. (No model.)
To all wifi/0m it may 00720671711:
Be it known that I, JOHN J. HENNEssEY, a citizen of the United States of America, and a resident of Milwaukee, in the county of Milwaukee and State of l/Visconsin, have in Vented certain new andV useful Improvements in Brackets for Sliding Doors, of which the following, taken in connection with the accompanying drawings, is a speciiication.
This invention has particular referenceto brackets such as are employed at the lowery ends of car-doors forsecuring the same in place, and has for its primary object the provision of a device of the class specified which will operate automatically to throw the door inward toward the side of the car into contact with the same when the door is to be closed and permit the door to swing away from the side of the car when it is to be opened, whereby it is capable of being moved longitudinally without rubbing against the side of the car.
The improvement embodied in my invention has especial reference also to door constructions in which operating devices are used whereby the door is raised and lowered when it is to be closed or opened; but since such operating devices form no part of my present invention I have not shown the same in connection therewith.
Referring to the accompanying drawings, it will be seen that Figure 1 shows a side elevation of the lower portion of a car-door with one of my improved brackets at each end thereof. Fig. 2 is a sectional viewthrough the door and car, showing the bracket in end elevation with the door in closed position. Fig. 3 is a view corresponding to the View in Fig.- 2, but showing the door in opened position or in a position about to be opened; and Fig. Il is an elevation of the bracket shown in end elevation in Figs. 2 and 3.
In carrying out my invention I provide iirst a body portion for the bracket, (marked 5,) which is arranged with means, such as the screws 6, for attaching it to the side of the car. Such body portion is formed with a lug 7, embraced between two side ears 8 of a pivotal part or toe 9, which is heldin pivotal engagement with the part 7 by means of the pin l0 and provided with a shoulder 11, oonstructed to be stopped by another shoulder- 12, formed on the body portion 5, when the toe 9 is inouter position, as shown in. Fig. 3. The toe 9 is formed with an extension 13, arranged so that it will when the toe is in the position shown in Fig. 3 bear against the lower end or edge of the door and when the toe is in the position shown in Fig. 2 will op erate to force the door inwardly against the side of the car, partly because of the inclined surface 14 and partly because the inward movementof the door, accompanied, as it is, by a downward movement thereof, tends to rotate the toe 9 upon the pivot-pin 10 and causes the same to act upon the door as a kind of cam or a lever of the toggle class, producing a movement of the lower edge of the door in a direction shown by the dotted curve marked 15 in Fig. 3 until the door strikes the side of the car and rests in the position shown in Fig. 2. f
The operation of my invention is as fob lows: Assuming the door to be in the position shown in Fig. 2, it is obvious that because of the incline 14 and of the circular movement of the toe 9 about the pin l10 the door will be held tightly against the side ofthe car until it is raised a slight distance, as it is in order to bring it to a position for opening it, when it will free the toe 9, so that the latter will by Virtue of the weight in the left-hand portion thereof swing outwardly into the posi= tion shown in Fig. 3, the projection 13 following upward under the bottom of the door, as shown in said Fig. 3. When the door is lowered in closing it, the weight thereof will bear downwardly upon the projection 13, and as the door swings inwardly the toe 9 will rotate upon the pin 10, causing an inward thrust or pressure against the door, tending to hold it firmly against the side of the car, as already described.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isef 1.
