To release the bolt, it is simply necessary to kick or pull up on the handle 16 of the cam, and as soon as the corner 15c passes over the head of the bolt the spring 13 operates to force the bolt to its position out of engagement with the floor.

If desired, sockets or keepers may be provided to receive the lower end of the bolt when the door is in its closed position; but for locking the door at points intermediate its closed and open positions I prefer to have the rubber foot of the bolt engage the surface of the Hoor or Hoor-covering.

It is evident that many slight changes might be resorted to in the relative arrangement of parts herein shown and described without departing from the spirit and scope of my in- Vention. Hence l would have it understood that I do not wish to conline myself to the exact construction herein shown and described; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a door stop or holder the combination with a casing and a bolt, the latter having a yielding lower end, the upper portion of the bolt and a portion of the lower end thereof being inclosed by the casing, and a spring ing the head of the bolt, and adapted when turned to depress the bolt and lock it in its depressed position.

2. In adoor stop or holder, the combination with a casing and a bolt the latter being composed of two telescopic sections, and a spring interposed between the sections for yieldingly holding the sections in their extended positions, a spring tending to normally hold the bolt in its elevated position, and a cam pivoted to the casing and engaging the head of the bolt and adapted when turned downwardly to depress the bolt and lock it in such depressed position.

3. In adoorstop and holder the combination with a casing made in two parts, a bolt also made in two parts slidingly connected together, a spring interposed between the two sections of the bolt, and a spring located within the casing and embracing' the bolt and tending to normally hold the latter in its elevated position, of a cam pivoted to the casing and engaging the head of the bolt and adapted when turned downwardly to depress the bolt and lock it in such depressed position.

ln testimony whereof l have signed this specification in the presence of two subscribing witnesses.
