‘This invention relates to door stops, and its
general object is to provide a device ~of that char
acter for disposal in the path of a swinging door
to hold vthe latter in open position andwhich is
5 actuated automatically for that purpose, merely
by the engagement of thedoor therewith.
A further object is to >provide a door stop that
isautomatic tothe extent above set forth, and
which must be manually` actuated toV release the
10 ,door,therefrom„merelyby slight pressure on. the
part of the user,.yet ,accidental releasing or clos
ing of the door,.suchas by aircurrents, windor
the like is impossible.
,
Anotherobject yis toeprovide- a door stop Lthat
' is adapted to be permanently` ñxed in position_for
use, is simple in construction, inexpensive toman
ufacture, easy to install, and extremelyelñcient
in operation, use andservice.

'I‘his invention also consists in certain >other
features of construction and in the .combination
and arrangement of the several parts, to be here
inafter fully described, illustrated in the_accom-
panyingdrawing .and44 specifically pointed out in
the'appended claims.'`
,
In describing the invention in detail, refer
ence will be had to the accompanying drawing
wherein like characters denote like or correspond

It is thought from the foregoing description
that the advantages and novel features of the
invention will be readily apparent.
It is to be understood that changes may be
made in the construction and in the combination
and arrangement of the several parts, provided
20 that such changes fall within the scope of the
appended claims.
WhatI claim is:
1. A door stop comprising means to be ñxed
in the path of a door, a slidably _mounted spring
25 pressed bolt associated with the ñxed means and
for disposal into and out of said
ably mounted and connected
movement therewith in unison,
normally holding the slidably
against movement and the bolt
path, means slid
to said bolt for
releasable means
mounted means
out of said path,
means included in the holding means to be en
gaged by said door for releasing the slidably
mounted means for disposing the bolt in said
Path for cooperation with the _ñxed means for
holding the door between the bolt and the fixed
means.
2. A door stop comprising a frame, means fixed
to said frame and to be arranged in the path of
a door, a bolt slidably mounted in the frame for
40 disposal into and out of said path, a rod slidably
mounted in said frame, rack and pinion means
connecting said bolt and rod for movement in
unison, means releasably connected to the rod for
normally holding the bolt out of said path, spring
means for urging the bolt in said path, means
included in the holding means and to be engaged
by said door for releasing the rod for disposing
the bolt in said path for cooperation with the
fixed means for holding the door between the
bolt and the fixed means.
3. A door stop comprising a frame, a pair of
tubes secured in said frame and one tube extend
ing above the frame for the upper end thereof
to be disposed in the path of a door, a bolt slid
ably mounted in the other tube for disposal into 10
and out of said path, means slidably mounted in
the extended tube, racks on the slidably mounted
means and bolt respectively, a pinion meshing
with the racks, spring means for the pinion for
urging the bolt into said path, means releas
ably connected to the slidably mounted means
for holding the bolt out of said path, and means
for actuating the holding means and mounted
on the upper end of the extended tube to be en
gaged by said door for releasing the holding
means for disposing the bolt in said path for co
operation with the extended portion for holding
the door between the bolt and extended portion.
4. A door stop comprising a frame adapted to'
be set into a floor, a pair of tubes mounted in the
frame and one of said tubes extending above the
frame for disposal in the path of a door, a'bolt
slidably mounted in the other tube, a rod slidably
mounted in the extended tube and having a
hooked upper end, racks secured to the bolt and 30
rod, a pinion meshing with the racks, spring
means for the pinion for urging the bolt into
said path, a spring pressed dog pivotally mount
ed in the extending portion of the extended tube
and engageable with the hooked upper end for
holding the bolt out of said path, a headed pin
engaged by the door to be actuated thereby for
releasing the dog from the rod for disposing the
bolt in said path for cooperation with the extend
ed portion for holding the door between the latter 40
and the bolt, and a cap for` closing the extended
portion.
