DOOR-CHECK;

SPECIFICATION forming part of Letters Patent No. 360,937, dated April 12, 1887.

Application filed February 26, 1887. Serial No. 228,952. (No model.)

To all whom it may concern:

Be it known that I, GEORGE 'WEINLEY, a citizen of the United States, residing at Rutland, in the county of Rutland and State of Vermont, have invented certain new and useful Improvements in Door Checks and Bolts;

and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to combined door checks and boltsthat is,to devices which are adapted to bolt a door at the bottom when in the closed position and to hold it in the opened or partially-opened position by engagement ofa pad or block with the floor or carpet-the objects vof my invention being to simplify the construction, lessen the cost of production, and at the in section on the line 00 w in Fig. 2 and the operative .parts shown in elevation; and Fig. 2 is aside elevation of the device complete.

1 denotes the base-plate, which is adapted to be secured to the lower edge of the door, near the corner,by screws, or in any suitable manner.

2 is a case for the operative parts, which is preferably secured to the base-plate by screws 3, which engage the case from the back.

4 denotes side flanges upon the base-plate, which engage theoppositesides of the case to hold it firmly in position and relieve the strain upon the screws.

5 denotes the bolt, which is preferably made angular and passes through a correspondinglyshaped opening, 6, at the bottom of the case.

7 denotes a block atthe lower end of the bolt, and 8 a pad, made of rubber or leather,-which is preferably secured to the under side of the block.

9 denotes a partition or crosswall in the case, through which the shank 10 of the bolt passes and by which it is steadied.

11 denotes a spring coiled about the shank of the bolt,the upper end of which rests against edge of thecase, theinner end of which extends. into the case and is connected to the bolt by alink, 13, the other end extending outward and being provided with a foot-piece, 14, having a rigid eye or loop, 15, on its under side.

16 denotes a retaining-lever pivoted between. ears 17 upon the base-plate. The upper end is adapted to engage eye or loop 15, and thus hold the bolt out of operative position, as in dicated in full lines in the drawings.

19 is a spring connected to the base-plate and to the retaining-lever above its pivotal point, the action of which is to draw the hook inward so that it will engage the eye. The upper edge of the hook is provided with an incline, 20, and the lower edge of the eye corresponding therewith is provided with an incline, 21, so that when lever 12 is pressed downward incline 21 will engageincline 20 and force the hook outward until the eye has passed below it. Spring 19 will then act to draw the hook into engagement with the eye and lock the bolt at its raised position. The lower end of the retaining-lever is preferably provided with a foot-plate, 22, against which the foot is pressed when it is desired to release the bolt, to lock the door or to hold it at its opened or a partially-opened position.

It will of course be understood that a suitable socket or recess is provided to receive the bolt in the sill at the base of the door. This, however, I have not deemed it necessary to illustrate in the drawings. It will be seen that when it is desired to either engage or disenof this lever is provided with a hook, 18,which i gage the bolt it may be accomplished byasingle operation of the foot. When the parts are in the position shown in full lines in the drawings, the door maybe opened and closed freely, the check being wholly out of operation. Suppose it was desired to lock the door at its closed position. Pressure against foot-plate 22 will act to draw the hook out from the eye, thus releasing lever 12 and allowing spring 11 to throw the bolt instantlyto the locked position. When it is desired to hold the door at anyintermediate position, it is first placed there, then lever 12 is released, and the door will be held at the desired position by the engagement of the pad with the floor or carpet. When the door is bolted or retained in the partiallyopened position, it may be released and the bolt locked in its raised position by simply pressing down upon foot-piece 14 until hook 18 has engaged the eye.

It will of course be understood that the details of construction maybe varied within reasonable limits without departing from the spirit of my invention.

1. The combination, with a spring-bolt, of a pivoted lever connected to said bolt and having an eye and a spring-hook adapted to engage said eye, whereby the bolt is-held at its raised position.

2. The springbolt, the pivoted lever connected thereto and provided with a foot-piece and an eye, and a pivoted retaining-lever also having a foot-piece, and a hook adapted to engage t-he eye.

3. Bolt 5 and spring 11, in combination with lever 12, a link connecting said lever with the bolt, a hook adapted to engage said lever to hold the bolt at its raised position,andaspring, 19, whereby said hook is held at its engaged position.

4. The bolt and spring 11, in combination with lever 12, connected thereto and having a foot-piece, an eye having an incline, 21, and a spring -hook having an incline, 20, whereby when said lever is pressed down the hook is pressed backward by the engagement of the inclines until the eye has passed below it, the hook then engaging the eye.

5. The spring, bolt, and 18VO1'12, connected thereto and having eye 15, in combination with a pivoted retaining lever having a hook adapted to engage said eye, spring 19, acting to hold said hook in its engaged position, and a foot-piece on said lever, whereby the book may be disengaged to release lever 12 and the bolt.

6. The spring, bolt, and lever 12, connected thereto and having an eye with an incline, 21,

in combination with pivoted lever 16, having a hook with an incline, 20, and a spring, 19, for throwing the hook to its engaged position.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE WEINLEY.
