Filed March 20, 1946 [NvmvToR C'HARL E5 HUGH MART/N Patented Oct. 19, 1948 UNITED STATES PATENT `OFFICE v 'I Y 2,451,848 I DOORSI'IQP Charles H. Martiri, ios Angeles, Calif. i L; Application March 20, 1946, Serial No. 655,706

its primary object to provide one which is effective in use but which can readily be bent or flexed in any direction by iioor cleaning instruments for cleaning access to floor areas beneath the stop.

Another object of the invention is to provide a door stop which can be flexed in any desired direction and to any desired degree without danger of overstressing the means permitting the flexing thereof.

My invention also has for its objects to provide such means that are positive in operation, convenient in use, easily installed in a Working position and easily disconnected therefrom, economical of manufacture, relatively simple, and of general superiority and serviceability.

The invention also comprises novel details of construction and novel combinations and arrangements of parts, which will more fully appear in the course of the following description. However, the drawings merely show and the following description merely describes one embodiment of the present invention, which is given by Way of illustration or example only.

In the drawings, like reference characters designate similar parts in the several views.

Fig. 1 is a broken plan view showing the door stop in applied position, the door stop being partly in section.

Fig. 2 is an end view of th'e door stop.

The door stop 5 of the present embodiment is shown applied on a base board B in a position to intercept a door D and to prevent the hardware of the latter from marring the surface of the wall W.

The door stop 5 comprises, generally, a base or escutcheon plate 6, a stem I centered thereon and extending transversely outward, means 8 connecting the plate and stem and including compresslble means 9 whereby said stem may be displaced with respect to its normal position but will return to its normal position upon release, and a bumper tip I0 on the outer end of the stem.

The escutch'eon plate which is illustrated is of generally oval form and is adapted to be permanently secured to a wall or the base board B thereof by screws I I either above and below or on either side of thestem 1. In its preferred form, an ear I2 is sheared and struck at right angles from the plate 6, said ear being provided with an eyeI I3.

The stem I simply comprises a thin walled tube of suitable length with one end provided with an inwardly directed annular flange I4. The bumper tip II) which' is made of soft rubber or like masclaims. (crisssi l l 2` 1 terial is insertable into the other end of the stem 1 as by means of its reduced cylindrical portion I5 so that its suitably domed head I 6 may serve to engage the door D to receive the shocks transmitted thereby.

The means 8 comprises a rod I'I having at one end a hook I8 engaged in the eye I3 and arranged longitudinally in the stem 1. The other end of th'e rod I1 may be threadedly or permanently connected to a plate or abutment Washer I9 slidably movable in the stem. When a threaded connection is used, the effective length of the rod may be varied.

The compressible means 9 comprises a coiled compression spring confined between the flange I4 of the stem and the mentioned abutment washer I9. Said spring can be variably loaded by adjusting the abutment washer I9 along the rod I'I.

The door stop above provided fully realizes the objects and purposes of the invention in a simple and effective manner. It will be noted that the spring 9, by reactive pressure, urges the flanged end of the stem 1 flat against the escutcheon plate 6 and, therefore, holds said stem in door shock receiving position outwardly at right angles to said escutcheon plate. However, a broom, mop, carpet sweeper, or vacuum cleaner will readily angularly displace or move the stem by a commensurate compression of the spring 9 as the displacement occurs. Inasmuch as the spring cannot be over tensioned, it retains its eifectiveness under all conditions and cannot lose its tension even under exaggerated displacement of the stem.

While I have illustrated and described what I now regard as the preferred embodiment of my invention, the construction is, of course, subject to modifications without departing from the spirit and scope of my invention. I, therefore, do not wish to restrict myself to the particular form of construction illustrated and described, but desire to avail myself of all modifications that may fall Within the scope of the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. In a door stop, a base plate for attachment to a baseboard and having an integral ear formed and extending outwardly from and at right angles to said plate provided with' an eye, a rod having a hook on one end eng-aged in said eye, an abutment plate on the rod, a tubular stem engaged over the rod and having an inwardly directed iiange and a central opening, and compressible means engaged with the abutment plate and the stem for normally holding the latter at right angles to the base plate.

2. In a door stop, a base plate adapted to be secured to a baseboard, said plate having struck therefrom an ear extending at right angles to said plate, a tubular body having an inwardly directed flange at right angles thereto and central opening, said ear extending into said opening and having an aperture, a rod within said tubular body having at one end a hook engaged in the aperture of saidar, ,and 4at the other and rfree'end, an abutment plate adjustable the on, and apring between said inwardly directed flange of said tubular body and said abutment plate for holding the tubular body at right angles to the base plate.

3. In a door stop, a plate for attachment to ua baseboard, said plate having an ear ,struol there-e from :and bent at a right angle tb said plate and said ear having -an aperture, a tubularbody having an inwardly directed flange at the bottom normally parallel to said plate, said apertured ear eX- tending into said tubular body, centrally of the flange thereof, a rod in said body having one end pivotally engaged in the aperture of said ear, and provided with threads at the other end, an abutment plate engaging the threads of said rod for adjustment thereon, and a spring surrounding said rod and disposed between said abutment plate and th'e flange of'said tubular body to maintain said tubular body normally at right angles REFERENCES CITED The following references are of record in the file of this patent:
