Patented Sept. 21, 1948 iJITED STATES PATENT OFFICE DOOR STOP Steven S. Brinda, Minneapolis, Minn.

Application 1 Claim.

My invention relates to door stops or buffers of the so-called right-angle type, that is, door stops of the type adapted to be secured to the floor as distinguished from the wall or baseboard mounted type.

The primary object of my invention is the provision of a door stop which is inexpensive to manufacture, rugged in construction, pleasing in appearance, and efficient in operation.

Another object of my invention is the provision of a door stop which can be quickly assembled, inexpensively shipped, and easily installed.

The above and still further objects of my invention will become apparent from the following detailed specification, appended claim, and attached drawings.

Referring to the drawings wherein like characters indicate like parts throughout the several views:

Fig. l is a View in side elevation, illustrating a position of my novel device with relation to a door or the like; and

Fig. 2 is a vertical axial section on an enlarged scale, some parts being broken away.

Referring with greater particularity to the drawings, the numeral I indicates, in its entirety, a body portion which preferably, and as shown, is in the form of an inverted L and comprises a normally vertical post 2 and a normally horizontal arm 3 projecting at right angles to the post 2 adjacent the top thereof. At its bottom, the post 2 is provided with a circumferential flange forming a base t. Post 2 has an axial passage 5 therethrough which is reduced or restricted adjacent the base 4, as indicated at 5, whereby to provide a shoulder 6. Anchoring means, preferably, and as shown, in the form of a screw '1 is positioned within the passage so that the pointed end 8 thereof projects outwardly through the restricted opening 5 and so that the head 9 rests upon the shoulders 6. It is apparent that the anchoring screw '1 is adapted to be secured to the floor A.

Arm 3 is likewise provided with an axial passage It which intercepts the axial passage 5 through the post 2. As shown in Fig. 2, the open outer end Ii of arm 3 is externally threaded to receive a sleeve I2, which sleeve has a reduced outwardly projecting end portion I 3. A head I4, preferably cylindrical in shape, is mounted in the passage ID of arm 3 for reciprocal movements therein. Secured to the head I4 and mounted for reciprocal movements in the reduced end It of sleeve I2, is a plunger I5, preferably provided at its extreme outer end with a cushioning pad I6 of rubber, felt or the like. Interposed between the head I4 and post 2 is a coil compression spring H which biases the head It and the plunger I5 in an outward direction and November 20, 1946, Serial No. 711,024

into contact with a shoulder it provided on the interior of the sleeve l2.

It will be observed that the coil compression spring I1 is axially-disposed with respect to the passage II] of arm 3 and extends transversely through the passage 5 of post 2. This is an important feature of my invention for it enables the anchoring screw 1 to be placed within the passage 5 of the post 2 at assembly, and thereafter shipped without fear of any of the parts, including the anchoring screw I, becoming disassociated from each other. Furthermore, for the purpose of shipping, the screw 1 may be pushed upwardly into the passage 5 to a point where the pointed end B does not extend outwardly through the restricted opening 5.

When installation or my novel device is desired, all that is necessary is to uncsrew the sleeve I2 from the arm 3 and thereafter remove the headed plunger I5 and spring I1. At this point, it is possible to insert a screw driver or the like into the passage 5 and drive the screw I into the floor A. 'After this has been accomplished, the spring I'I, headed plunger I5, and sleeve I2 are replaced and the device is in condition for operation.

My invention has been thoroughly tested in a commercial manner and has been found to be completely satisfactory for the accomplishment of the above objects.

What I claim is:

In a device of the class described, a post having an axial passage therethrough, said passage being reduced adjacent its base to provide a shoulder, an offset arm adjacent the upper edge of said post, an axial passage through said arm intercepting the passage in said post, a. removable sleeve secured to said arm and having a reduced outwardly extended end portion, a head mounted for reciprocal movements in the passage of said arm, a plunger secured to said head and mounted for reciprocal movements in the reduced end portion of said sleeve and havin its outer end projecting outwardly therefrom, and spring means biasing said head and plunger in an outward direction.

STEVEN S. BRINDA.
