Specification of Letters Patent.

Patented July 3, 1906.

Application filed January 19,1906. Serial No. 296,851.

To all 7071,0712, it WWI/:1] concern:

Be it known that I, GEORGE E. HASSMANN, a citizen of the United States, residing at Springfield, in the county of Sangamon, State of Illinois, have invented certain new and useful Improvements in Door-Checks; 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 to make and use the same.

This invention relates to builders hardware, and more particularly to door-checks, and has for its object to provide a device of this kind which will be extremely simple and cheap and which will be arranged to hold a door at any desired point of its movement.

Other objects and advantages will be apparent from the following description.

In the drawings forming a portion of this specification and in which like numerals of reference indicate similar parts in the several views, Figure l is a vertical section of a door, showing the present invention applied thereto and in operative position. Fig. 2 is a view of the door in elevation, the check being in operative position. Fig. 3 is a transverse section taken through the door, the plate, and the rod horizontally. Fig. 4 is a detail view of a lower end of the rod and the floorengaging member, showing the connection therebetween. Fig. 5 is a detail view show ing the rod connected with the door-knob for movement when the latter is revolved.

Referring now to the drawings, there is shown a door 5, having a vertical passage 6 formed therein adjacent to its free edge and opening through its lower edge, the door having a vertical slot 7 therein communicating with the passage 6 at the upper end thereof, and the slot has at its upper end a lateral extension 8.

Secured vertically within the passage 6, at.

the lower end thereof and at the side of this passage which lies away from the direction of movement of the door into closed position, there is a plate 9, having transverse serrations 10, and disposed loosely within the passage there is a vertical rod 11, having a floorengaging block 12 at its lower end of rubber or similar material. This block is detachably connected with the rod, so that it may be removed when replacement is necessary.

The rod 11 has transverse serrations 13 thereon, arranged for engagement of the sermovement, and at its upper end the rod 11 is turned laterally to extend outwardly through the slot 7, the outer end of the laterallyturned portions having a head 14 thereon. The laterally-turned portion may be moved into the lateral extension 8 of the slot 7 and when thus engaged holds the rod at the upward limit of its movement and with the member 12 out of engagement with the floor.

WVhen the check is to be moved into operative position, the rod 11 is moved downwardly to engage the member 12 with the floor, when the tendency of the door to close itself will bring the plate 9 against the rod 11, intermeshing the serrations 10 with the serrations 13, and thus holding the rod with the member in operative position. It will be seen that as the floor-engaging member is worn away the rod may be moved farther downwardly to compensate for such wear.

It will be understood that the head 14 lies in spaced relation to the outer surface of the door to permit of lateral movement of the rod 11 within the passage.

In Fig. 5 there is shown a form of the invention in which the rod 11 is connected with the sleeve a of a door-knob A by means of a flexible connection B for vertical movement of the rod to bring the block 12 out of engagement with the floor when the knob is revolved. It will be readily understood that the door is first moved to bring the serrations 10 and 13 out of intermeshing engagement, and the knob is then revolved to raise the rod 1 1.

What is claimed is 1. The combination with a door having a vertical passage therein openin through its lower edge, of a plate disposed within the passage at one side thereof and having transverse serrations, a rod disposed within the passage for vertical movement, a floor-engaging member carried by the rod, means for holding the rod with the floor-engaging member in inoperative position, said rod having serrations for engagement with those of the plate and being movable at its lower end with respect to the'door to engage its serrations with those of the plate to hold the rod against upward movement.

2. The combination with a door, of a rod connected therewith, a floor-engaging member carried by the rod, said rod being arranged for movement to bring the floor-engaging member into and out of operative porations 10 to hold the rod against vertical 1 sition, means for holding the rod against IIO vertical movement, said rod being movable In testimony whereof I afi iX my signature litterally at its lower end with respect to tllie in presence of two witnesses.
