DOOR-HOLDER.

SPECIFICATION forming part of Letters Patent No. 646,517, dated April 3, 1966. Application filed December 30, 1899. Serial No. 742,090. (N inod) T0 all whom it puny concern.'

Be it known that we, J AMES M. GHEITTON and JAMES ANDREW GOODNER, citizens of the United States, residing at Pueblo, in the county of Pueblo and State of Colorado, have invented a new and useful Door-Holder, of which the following is aspecification.-

The invention relates to improvements in door-holders. v y v The object of the present inventionv is to improve the construction of door-holders and to provide a simple, inexpensive, and eiiicient device designed to be applied to various kinds of doors, windows, and analogous swinging` members and capable of holding such door or member in an open or closed position or at any intermediate point.

A further object of the invention is to provide a device of this character which will not mar the carpet or the wall of aY room and which will be capable of effectually lookin g a door in its closed position.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In'thedrawings, Figure 1 is a perspective view of a door-holder constructed in accordance with this invention Vand shown applied to a door. Fig. 2 is a sectional view, partly in elevation. Fig. 3 is an enlarged. detail perspective view of the clutch. Fig. 4 isa detail perspective viewillustrating the 1n an'- ner of mounting the swinging arm. Fig. 5 is a detail sectional viewillustratin g the means forlocking the door in its closed posit-ion.

Like numerals of reference designate corresponding parts in all theligures ofthe drawings.

1 designates a horizontally-disposed oscillating arm pivotally mounted at its inner end on a bracket 2 by means of a rivet 3 or other suitable fastening device, and the said bracket, which is substantially L-shaped, as

clearly illustrated'in Fig. 4 of the accompanying drawings, `is located above the door and preferably secured to the doorframe, as clearly shown in Fig. 1. The oscillating arm is adapted to swing horizontally, as the door opensand closes, and it slides through openings 4 of substantially L-shaped clutch-levers 5 of a swiveled clutch 6. The clutch 6,which has a swivel connection with a horizontal rocktal arm supports the casing, which is provided with side and end walls and within which are fulcrumed the said levers. The levers, which are L-shaped, are fulcrumed at their angles in the casing at the ends thereof, being retained in position by transverse fastenings devices 11. The engaging arms of the clutch-levers are maintained in contact with the horizontal arm 1 by a coiled spring12, disposed on the said rod or arm 1 and interposed between the levers, as clearly shown in Fig. 2. The openings 4 of the clutchlevers are of greater diameter than the rods, and the latter when thrown outward by the spring engage the swinging arm or rod 1 at the upper and lower faces of the same. The spring maintains the lower arms 14 of the leversslightly elevated, and these arms 14 are adapted to be engaged by a stem 15, extending through the casing and the supporting-bracket and having its lower end connected with the adjacent end of the rock-shaft. The upper end of the stem is provided with a head and carries a plate or disk 16a, which is arranged above the inner arms 14 of the clutch-levers, and the lower end of the stem is provided with an eye through which extends an arm 16 of the rock-shaft, whereby when the rock-shaft is rotated to swing its arm 16 downward the engaging arms ofthe clutchlevers will be swung inward against the action of the spring and will release the rod 1. The clutch-levers are held loosely in the open casing by the said transverse fastening devices 11, and they are automatically engaged with theswinging rod or arm 1 when the operating mechanism is released.

The rock-shaft, which extends horizontally across the top of the door, as shown inFig. 1, is provided at one. end with the said arm 16 and at its other end with an arm 18, and it is journaled in a bearing 19 of the bracket 10 Aand in a bearing of a bracket 20. The bracket IGO 2O is secured to the door, near the free edge thereof, and the adjacent arm 18 is connected by a rod 2l with a plate 22, provided with a threaded opening for the reception of the lower threaded end of the rod 2l and having side openings 23, through which pass reversely-reciprocating rods 24. The reverselyreciprocating rods 24, which are disposed approximately vertical, are provided at their upper ends with heads for engaging the face of the plate 22, and the lower ends of the rods 2l are provided with eyes 25, through which pass screws 26 or other suitable fastening devices for pivoting the said rods 24 to a double eccentric 27. The double eccentric 27 consists of a disk or plate mounted on the knob-spindle 28 of a lock and provided with a rectangular opening for the reception of the said spindle, and the said eccentric by being arranged in this manner is adapted to be applied to both mortise and face locks. When the knob is turned and the spindle rotated, one of the rods is carried downward and the other-upward. Thedownwardly-movable rod 24 carries the plate and the connecting-rod 21 with it and rotates the rock-shaft, and thereby disengages the clutch from the horizontallyswinging rod or arm. By this construction the clutch may be operated when the knob is turned lin either direction, and as the clutch is swiveled to or pivotally mount-ed on the bracket 10 and is adapted to slide longitudinally of the horizontally-swinging rod or arm it will be readily apparent that the lmechanism is adapted to accommodate itself to the position of the door and is capable of holding the same in its open or closed position or at any intermediate point. The rod 21 passes through an opening of a bracket 29, upon which is mounted a clamping-screw 30,'extending through a horizontally-threaded perforation of the outer portion of the said bracket 29 and having its inner end arranged to engage the rod, whereby the latter is held against longitudinal movement. When the door is closed, it may be locked in this position by clamping the rod 2l with the screw, and when therod is thus clamped it will prevent the knob and the lknob-spindle from being rotated. The clamping-screw is also adapted to lock the door-holder out of operation, and this is effected by rotating the knob as far as possible to the right or left and holding it in such position until the screw 30 is engaged with the connecting-rod 21. This will disengage the clutch-levers from the arm 1 and will prevent them from rengaging the said arm when the knob is released. The knob will thenbe free to turn without affecting the door-holder.

It will be seen that the door-holder is `simple and comparatively-mex pensive in 'construction, that it is adapted to be applied to doors having mortise or face locks, and that it will not mar the carpet or wall of a room. The device is also applicable to screen-doors, shutters, trunklids,'and analogous swinging elias?? members, and it will prevent such parts from' slamming or closing violently.
