forth in the specification and pointed out in the claims.
In the drawings, Figure 1 is a perspective of a portion of a door with parts broken away, showing our invention applied thereto; Fig. 2 is a cross-section on the line 2--2 of Fig. 1 taken through the lockcasing only, the door being omitted and showing the cord-winding disk in locked or position; Fig. 3 is a similar section showing the disk disengaged for winding, a portion of the key by which the disk is manipulated being also shown; Fig. 4 is a side view of the bottom portion of the lockj casing, parts being broken; Fig. 5 is a side view, with parts in section, of the casing confining the plunger of the door-stop; Fig. 6 is a view at right angles to Fig. 5; Fig. 7 is a cross-section on the line 7-7 of Fig. 5; Fig. 8 is a face view from one side, of the cord-winding disk; Fig. 9 is an edge view thereof; Fig. 10 is a view of the opposite face of said disk; Fig. 11 is a section on the line 11-11 of Fig.9; and Fig. 12 is a plan of the key by which the disk is manipulated.
The object of our invention is to construct a spring-controlled door-stop which may be released, or raised out of engagement with the floor by the manipulation of a winding disk through the medium of a key in the hands of the operator, a cord connected to the plunger or stem of the stop and to the winding disk serving to raise the stop with the turning of'the disk in either direction.
A further object is to construct a stop which will be cheap, durable, reliable, one readily applied to the door, and one possess ing further and other advantages better apparent from a detailed description of the invention which is as follows:
Referring to the drawings, D, represents a swinging door and F the floor over which it is mounted.
C, represents the lock-casing as usual, the same being in the present instance extended to accommodate the parts forming a portion of the subject matter of the present invention.
P, represents the side plate opposite the casing C, and which supports the shank of .the door-knobs K as well understood in'the art. In the bottom of the casing C is a peripherallygrooved disk 1 one face of which is provided with a depression d for the reception of one end of a compression spring 2, the opposite end of the spring being preferably, (though not necessarily) fastened to the wall of the casing. The opposite face of the disk is provided with a series of depressions 3 arranged along a common circle, the center of the disk being provided with a square opening 4. Through this opening 4, is adapted to be passed the square portion a of a key 7), the shank of the key beinginserted through the circular opening 0 formed in the side wall of the casing, a similar opening (not shown) being formed in the plate P through which the key-shank is inserted, it being understood of course that the casing C is embedded in the*- door in the illustration here used as an example.
Secured to the casing wall opposite the circle of depressions or sockets 3 is a nipple or stud 5, which, upon release of the disk 1, and when the latter is turned to bring one of the depressions opposite thereto, enters such depression thereby arresting further rotation of the disk and hence locking the same. The portion a of the key terminates in a spindle portion 0 which passes freely through an opening in the opposite wall of the casing, and in the opposite plate P on the door (only one plate appearing in the perspective Fig. 1). The body of the disk 1 has formed angular grooves h through which is inserted one end of a wind ing cord 6 thus effectively fastening the same to the disk (although any other means of fastening the cord will answer the purpose), the cord running down through a bore or chamber 7 cut in the door, the lower end of the cord being fastened or knotted to a pin 8 projecting radially from the stem or plunger 9 of the door-stop, the stop proper being in the form of a cupshaped head 10 secured by a screw 11 to the bottom of the stem, and adapted, when the stem is raised its full limit to enter a pocket 12 formed in the bottom of the door D (dotted showing in Fig. 6).
The stem 9 is mounted in the bottom casing H which is inserted in the door and secured thereto by the flange 13 very much on the order of the casing G. The stop is forced into engagement with the floor by a compression spring 14: coiled about the upper reduced portion of the stem 9 within the casing H, one end of the spring bearing against an annular shoulder 15 formed on the stem at the base of said reduced portion, and the upper end bearing against a shoulder 16 formed on the inner wall of the casing H. Above the shoulder 16 the wall of the casing H has cut therefrom a spiral slot or way 17 through which the pin 8 projects and between the sides of which it is free to ride. The ends of the slot 17 are substantially in the same vertical plane, the upper end terminating in an enlargement or lobe 17, and the opposite end in a vertical leg 17, said parts 17 17 representing the limits of movement of the pin 8. The base of the lobe 17 is provided with a horizontal edge 6 serving as a rest for the pin 8 when the stem 9 has been raised to its upper limit for disengaging the stop 10 from the floor.
The operation of the door-stop is substantially as follows: assuming the stop 10 to be in its lowest position and the pin 8 practically settled in the leg 17", the disk 1 being locked to the stud 5 as indicated in Fig. 2. To raise the stem 9 and thus disengage the stop 10 from the floor, the operator inserts the key 1) into the socket l of the disk 1, pushes the key inwardly (the shoulder .9 formed at the base of the square portion a bearing against the disk) sufliciently to compress the spring 2 and thereby disengage the disk from the stud 5 (Fig. By now rotating (in proper direction) the disk 1 thus disengaged (by rotation of the key in the hand of the operator) the cord 6 will be wound on the disk thus drawing on the pin 8 and pulling up the stem 9. Since the pin 8 must traverse the spiral slot 17 with the raising of the stem 9, the latter will have imparted thereto not only a vertical upward movement but a rotary movement as well, the ends of the spiral slot being substantially diametrically and diagonally opposite one another (Figs. 5, 6). As the pin 8 traverses the slot 17 .it finally settles on the edge 25 at the base of the lobe 17 thus holding the stem 9 elevated. At the same time the operator releases the disk 1, the spring 2 forcing the latter toward the wall of the casing carrying the stud 5. The turn given to the disk for drawing up the stem 9 brings one of the sockets 3 opposite the stud 5, so that the latter may reengage the disk and prevent the latter from turning. Of course without the seat or edge if the locking of the disk would keep the stem 9 up, against the tension of the spring 141- which tends to drive it down, but the rest afiorded the pin 8 by the edge It relieves the cord of any strain, and the purpose of the said rest is to take the strain off the cord for a disengaged position of the stop. To release the stop, the operator again inserts the key Z), disengages the disk 1 from the locking stud 5, gives the disk a slight turn to raise the pin 8 well into the lobe 17, and by allowing the stem to drop suddenly the pin 8 rides over and past the edge 2, after which it follows the spiral 17 downward until it settles to its lowest position in the leg 17. Of course to allow the stem to drop, the operator must keep the disk 1 disengaged from its stud 5, so as to allow the disk to turn in the opposite direction to conform to the drop of the stem 9. The length of the cord is such, and the number of sockets 8 is such, that with a given turn of the disk to either lower or raise the stem 9, a socket 3 will be brought opposite the stud 5 to engage it, the moment the disk is released, and the spring 2 allowed to act. A gradual movement of the pin 8 to the edge 2? will allow the pin to settle on said edge without slipping off but a sudden movement downward will allow it to slip off, the inclination of the edge 6 being such as not to offer any impediment to the pins downward movement when released suddenly from its upper limit in the lobe 17. The size of the lobe 17 is sufiicient to allow the pin 8 to be raised sufliciently above the edge or seat 2,, so that if the stem 9 is suddenly released, the pin will pass off said edge and allow the stem with its stop 10 to drop to its lowest position under the action of the spring 1 1, whereupon the cup-shaped rubber head 10 is forced into firm contact with the floor. The cup-shaped terminal of the head 10 causes the latter to act as a sucker and thus exert a grip on the floor.
Having described our invention what we claim is:
1. In combination with a door, a reciproeating spring-controlled door-stop mounted thereon, a key operated rotatable disk mounted above the stop, a cord secured to the disk and stop respectively and winding on the disk, means for locking the disk against movement upon conclusion of a rotation to effect a release of the stop from the floor, and means for affording an independent support for the stop in its released position to relieve the strain on the cord.
2. In combination with a door, a casing on the bottom thereof, a spring-controlled rotatable stem mounted to reciprocate within the casing, a stop-head at the lower end of the stem adapted to engage the floor, the wall of the casing being provided with a spiral slot having terminals diagonally op-' posite each other, the upper end terminating in an enlargement or lobe having a seating edge at the base thereof, a pin projecting from the stem and traversing said slot, a key-operated rotatable grooved disk mounted above the door-stop casing, a cord connected to the disk and door-stop stem respectively and winding about the groove of the disk, means for arresting the movement of the disk upon a rotation of the latter to disengage the stop from the floor, or upon reengagement of said stop with the floor.
3. In combination with a door, a springcontrolled reciprocating door-stop mounted at the bottom thereof, a casing above the same, a rotatable peripherally-grooved disk mounted in said casing, a stud on the inner Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,-
