DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 670,821, dated March 26, 1901.

Application iiled July 6. 1900. Serial No. 22,682. (No model.)

To all whom t may concern:

Be it known that I, GEORGE STUBBS, a subject of the Queen of Great Britain, residing at Perth, in the Colony of Western Australia, have invented a new and Improved Door- Gheck, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved door-check which is simple and durable in construction, cheap to manufacture, and arranged to form an ornament for a door, to permit the operator to convenientlybring the check into action'for holding the door in an open position, and to allow of moving it into an inactive position when it is desired to freely open or close the door.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinaftei` and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this speciiication, in which similar characters of reference indicate corresponding parts in all the views.

Figure lis a perspective view of the improvement as applied and with parts in an active position to hold the door open. Fig. 2 is an enlarged transverse section of the same. Fig. 3 is a section on line 3 3 of Fig. 4L. Fig. 4 is an edge View of the operating mechanism for the check-bolt with the front part of the housing in section. Fig. 5 is an enlarged rear elevation of the check-bolt casing and retaining device for holding the parts in position for shipment, and Fig. 6 is a sectional plan view of the same on the line 6 6 in Fig. 5.

The housings A and B are secured by screws or other means to the inside of the door C, as is plainly illustrated in Figs. l and 2, and the lower end of the housing A is formed with a guideway A for a check-bolt D, preferably made of rubber or like elastic material, adapted to engage the door when the door is open, so as to hold the door against accidental closing. The check -bolt D is secured on the lower end of a rod E, extending vertically to `slide in suitable bearings A2 and B', formed ing A. A washer E is secured on the rod E within the housing A, and said washer is pressed on by one end of a spring F, coiled around the rod E and resting with its upper end on the bearing A2, so that said spring F exerts a downward pressure on the rod E and check-bolt D to hold the latter with the desired force in contact with the floor to prevent the door from accidentally closing.

The upper end of the rod E is pivotally connected with a lever G, fulcrumed on a pivot-pin H, carried by the housing B, said' pivot-pin extending through an elongated slot G' in the lever G to permit the latter to swing and to slide on said pivotepin H. The shank of the lever G is adapted to rest on a shoulder B2, formed on one side of the housing B, adjacent to slot B3 in the housing B, aspring I pressing said lever at the time the latter is seated on said shoulder B2.

When the lever is in an uppermost position and is seated on the shoulder B2, then the rod E and the check-bolt D are likewise in their innermost positions, the lower end of the check-bolt being Hush with the under side of the housing A and the bottom of the door `C to permit of freely opening or closing th door in the usual manner.

When the door has been swung open and it is desired to lock the door against accidental closing, then the operator takes hold of the free or handled end G2 of the lever G and first moves the same forward off the shoulder B2 and then releases the lever to allow the spring F to move the rod E and the check-bolt D downward to cause the check-bolt to engage the iioor, and thus hold the door against m0vement. During the downward movement of the rod E a like movement is given to the lever G, which swings at its free end in the slot B2, it being understood that the lever Gduring its downward movement also slides with its fulcrum end on the pivot-arm H, and this movement is necessary owing to the vertical movement of the rod E.

lVhen it is desired to unlock the door, then the operator takes hold of the end G2 of the lever Gand swings the same upward and seats the same on the shoulder B2, thereby drawing the check-bolt D out of engagement with the door, as previously stated.

IOO

When shipping the device, it is desirable one fork member a groove E2 in said, rod, asV

is plainly indicated in Fig. 6. lThe, lockingplate J is adapted to rest on the vtop of the 'housing A and engages the groove E2 at the time the check-bolt D is withdrawn, so that the several parts are held in this locked position and the device can be readily shipped from one place to another, it being, however, expressly understood that the plate J is not used and does not form part of the device after the device is once attached to the door.

The housings A and B are placed a sufcient distance apart to permit the operator to conveuienly manipulate the lever G, as described, and without assuming a stooping position.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- Al. A door-check, comprising a check-bolt, a spring-pressed rod carrying said check-bolt at one end, a lever pivotally connected with the other end of the rod and capable of sliding on its fulcrum, and means for holding said lever in a locked position when said check-bolt is withdrawn against the tension of the spring of the rod, as set forth.

2. A door-check, comprising an upper and lower housing having alined bearings and adapted to be fastened to the door, a checkbolt slidable in the lower housing, a springpressed rod mounted to slide in said bearings, and a lever in the'upper housing and having an elongated slot for the passage of the pivot of the lever, to allow the lever to swing and to slide on the pivot, as set forth.

3. A door-check, comprising an upper and lower housing having alined bearings and 'adapted to be fastened to the door, a checkbolt slidable in the lower housing, a springpressed rod mounted to slide in said bearings, a lever in the upper housing and having an elongated slot for the passage of the pivot of the lever, to allow the lever to swing and to slide on the pivot, and a support on said upper housing for the free end of the lever to rest'on when in an uppermost position, as set forth.

Ll. A door-check, comprising an upper and lower housing having alined bearings and adapted to be fastened to the door, a checkbolt slidable in the lower housing, a springpressed rod mounted to slide in said bearings, a lever in the upper housing and having an elongated slot for the passage of the pivot of the lever, to allow the lever to swing and to slide on the pivot, a support on said upper housing for the free end of the lever to rest on when in an uppermost position, and a spring secured to the upper housing and adapted to press said lever when in an uppermost position, to hold the lever to its seat on said support, as set forth.

5. A door-check, comprising an upper and lower housing, a spring-pressed rod slidable in said housings and provided with a slot, a check-bolt, an operating-lever for the rod, and a removable device for temporarily holding the parts in position when the check-bolt is withdrawn, said device consisting of a forked locking-plate for straddling said rod at the slot therein, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE STUBBS.
