1 Claim.

My present invention relates to an improved door stop of the type adapted to'be secured to the lower portion of the door and pivotally movable manually to engaging position with regard to the floor so as to retain the door in set position.

The stop of my invention consists generally in a body having a fiat side for engagement with the floor and a curved side, the two said sides being eccentric so that the curved side clears the floor while the flat side when swung down engages the floor. Spring means associated with eccentric pinson the shafts of the body releasably retain the body in adjusted position.

In the accompanying drawings I have illustrated one complete example of the physical em-- bodiment of my invention according to the best mode I have thus far devised, but it will be understood that various changes and alterations may be made in the exemplified structure within the scope of the appended claim.

In the drawings:

Figure l is an end elevational view of the door stop of my invention in non-engaging position.

Figure 2 is a similar view showing the stop partially pivoted and ready for engagement.

' Figure 3 is a similar view showing the fiat side of the stop engaging the floor.

Figure 4 is a front elevational view of the stop.

Figure 5 is a top plan view thereof.

Referring now to the drawings wherein I have illustrated the present preferred embodiment of my invention I have shown the door stop of my invention as used with the door 2 and comprising the bracket or base plate 4 secured to the lower portion of the door as by screws 6. The bracket plate has outwardly extended springs 8 formed at their ends into curved journals ID for the ends of the stud shaft 12 of the stop body M. This body has a pair of flat parallel walls, a flat side I6 and an arcuate side I8, the stud shaft being located eccentric of the body with the center thereof spaced a greater distance from the flat side than from the arcuate side, whereby the arcuate side clears the floor while the fiat side will engage the floor with the stop inverted. The corners 20 at the ends of the fiat side are rounded and the sides between the fiat and curved sides are inclined.

On the shafts I2 I provide eccentric pin extensions 22 which engage spring arms 24 also extending outwardly of the bracket plate 4 and the eccentric pins are positioned to tension the elements and resiliently hold the stop body when the fiat side is down. These spring arms merely bear upon the pins when the body is up.

As shown in the various views the fiat side of the body is normally up and is retained in that position by the spring arms acting upon the eccentric pins.

However to secure the door the body is swung manually until the corner 20 engages the floor whereupon the door is moved slightly to complete the pivotal movement and bring the fiat side into parallel position with the floor and in engagement therewith under tension of the spring arms 8 and the pins.

Retrograde movement of the door will pivot the stop in reverse position and put the curved side down to clear the floor.

The door stop of my invention is simple to manufacture and use and may be installed with a minimum of tools and effort and will securely secure the door in selected position.

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

A door stop comprising a base plate having spaced pairs of adjusting position outwardly extended spring arms, the inner of said spring arms of each pair having cylindrical sockets in the ends thereof, a body having a flat base with an arcuate upper side, and a shaft extended through said body and positioned on a center a greater distance from the flat side of the body than from the arcuate side, the ends of said shaft being journaled in the cylindrical sockets at the ends of said spring arms, the said ends of the shaft having pins eccentrically positioned thereon and extended therefrom, and said pins positioned to engage the outer of said spring arms of the pairs extended outwardly from the base plate whereby the said body is resiliently retained in a position with the flat side thereof extended upwardly.
