6 Cllllml.

The shaft of the screw I4 passesthreugh the gaged by a door when the door is swung open slot I2 and has screw-threaded engagement with 5 for the purpose of cushioning the impact of the apost I1. which is interiorly threaded'at one end 5 door and stopping it from striking the wall, and to eigage said bolt. The opposite end of the post particularlythe invention relates to a device of is formed with a socket I8 for engagement with this character which is so formed as to provide the screw-threaded shank of a bolt I9, thehgad not only a stop but a holder which will engage 2II of this bolt being embedded within the central* 10 the door when the door is swung fully open and portion of a rubber suction cup 2l.

The center of the cup is formed device for this purpose, which includes cushionwith a central hub 23 within which the screw I9 ing means and also includes a suction cup which, and its head 20 is embedded. 15 t when the door strikes it, will adhere to the door l Disposed concentrically to the DOSI; Il is a and will hold the door open. cylindrical shell 24 whose outer end is flanged at Another object is to provide a door stop and 25 to iit within an annular seat formed in the holder or the character stated in which the stop base of the cup 2 I The inner end portion of this Y is swingingly mounted upon the base so that the shell 24 is outwardly expanded at 26.

Disposed between the inner Mvv invention is illustrated in the accompany.. end of the shell 21 andthe expanded portion 26` ing drawing wherein: of shell 24 is a coiled compression spring 30. Figure 1 is a top plan view of the stop and a 1t will be seen that the ilange 29 forms a sockportion 0f the skirting board, the door being et for the reception of the hemi-spherical boss II 35 shown in dotted lines. and that the face I6 of the screw head I5 bears Figure 2 is a vertical section through the stop. against and conforms to the curvature of the in- Figure 3 is a. face view of the base of the stop ner face of this boss II. Thus a ball and socket Referring to this drawing, III designates the .'Ont is formed between the section 21 and theA 40 base which is preferably of metal and which at boss II and between the post I1 and the boss II. 40 its center is formed with a, bami-spherical buss It iS t0 be noted that the inner face 0f the Screw- I I, this boss having a transversely extending slot head I5 is spaced from the base board A so that I2, The ,base is formed with epenings I3 wherethe post I1 may move inward a distance before by it may be attached 'to the base beard A by striking the face of thebase board.

When the slighty (lished/s0 that the central portion of the door B is swung open and toward the wall, the base is out of contact with the base board A and door will strike one margin of the suction cup 2| only the periphery of the base comes in contact and this will cause the door stop t0 Swing freely with the base board. By dishing the base, as deto the position shown in dotted lines in Figure 1, 5o scribed, the screws will more tightly hold the base and the further movement of the door will cause ,to the base board A than it the base were dat. the attening of the suction cup against the face'V Extending through the slot I2 in the boss I I is a of the door. The impact of the door against the bolt I4 having a head I5, that portion of the suction cup will force the section 24 of the shell head connecting with the shank of the bolt being 'inward against the action of the spring 30 and 55 the door against the suction cup will act to hold the door in piace against the stop until the door is manually or forcibly pulled away `from the suction cup. The air,that is'enclosed within -the shells 24 and 21 will be forced out through the ends of the slot i2 and into the space between the dishedbaseandtheiaceofthebaseboardA, thus acting as a pneumatic cushion.
It will be seen that by rotating the bolt Il by means of the head I5, the post I1 may be drawn inward and this will draw the suction cup inward and force the shell section -24 inward into the shell section 21, thus this device has a certain lrange-of adjustment and may be re-adjusted from time to time by removing the screws holding the base to the base board A, then re-setting the screw I4 to the desired amount.
In actual practice, this structure acts as stated. in that if the door be forcibly thrown open against the suction cup, the blow of the door will be cushioned and the suction cup will hold the door from reverse movement until the door is pulled open. Y.
What is claimed is:- l
1. A door stop and holder, including a b ase for attachment to a base board, a two-part shell, one section of which has free rocking engagement with the base at all times. the other section having telescopic engagement with the nrst named section, a spring urging the sections outward relative to each other and resisting inward movement oi the outer section, and a suction cup attached to the outer end 'of the second named section.
2. A door stop and holder, including a base formed for attachment to the base board of a room, a two-part shell, one section oi' which has free rocking engagement with the base at all times, the other -section having telescopic engagement with the ilrst named'section, a spring disposed within the sections bearing against the inner section and urging the outer section outward, .a suction cup attached to the outer end of the outer section, and means hunting the outward movement of the outer section under the action of said spring.
3. A door stop Aand holder, including a base i'ormed for attachment to the base board of a room, a two-part shell, one section of whichhas free rocking engagement with the base at all times, the other section having telescopic engagement with the ilrst named section, a spring disv posed within the sections bearing against the inner section and urging the outer section outcenter of the suction cup and extending loosely through said sections of the shell and having rocking and sliding engagement with the base.
4. A door stop and holder, including a base having means whereby it may be attached to a base board, the center of the base having a hemi-spherical boss formed with a transversely extending slot, a shell formed ot two telescopically related sections, the inner section of the shell having, a central opening and formed with an inwardly extending annular flange forming a socket coacting with the hemi-spherical boss, the socket being free to swing upon the boss at all times, a suction cup mounted upon the outer end oi the `outer section of the shell, a spring disposed in the shell and urging the outer shell tioncup and the boss and limiting the outward movement of theouter section ofl the shell with its suction cup but permitting inward movement of the outer section of the shell and the sucscopically related sections, the inner section of the shell having-a central opening and formed with an inwardly extending annular flange forming a socket coacting with the -hemi-spherical boss, the socket being free to `swing upon. the boss at all times, a suction c up mounted upon the outer end of the outersection oi the shell, a spring disposed in the shell and. urging the outer shell outward, a post having interior screw-threads at its inner end and disposed within the two sections of the shell, the outer end ofthe post having means for anchoring it to the suction cup, and a bolt extending through the slot of the boss and having screw-threaded engagement with the post, the. bolt having a head, the outer face of the head being rounded to t against theinner rounded tace of the boss.
6. A door stop and holder, including a, base for attachment to a base board, a two-part shell, one section of which has free rocking engagement with the base at all times, the other section having telescopic engagement with the rst named section, a suction cup engaging the outer end oi' the second named section, and means urging the sections outward relative to each other.
