DOOR STOP AND HOLDER.

Application filed July 12,

To all whom. it may, concern Be it known that I, lutnnron H. Fonon, a citizen of the United States, and resident of Danville, in the county of Vermilion and State of Illinois, have invented certain new and useful Improvements in a Door Stop and Holder, of which thetollowing is a specification.

My invention. relates to door holding devices and particularly to novel mechanism having unusual characteristics of etliciency and certainty of operation.

It is common to employ a door stop or holder particularly on doors which utilize a spring closer. Such stops are so constructed that by a single movement of the foot the door holding device may be firmly positioned and released as desired. However, some difficulty is experienced in securing efficient operationwhere the floor adjacent to the door is uneven, due to the fact that there is insufficient contact of the rigid holding device with the floor.

In the device of this invention I provide means whereby the floor-contacting foot, which is usually of rubber or similar resilient material has a limited capacity for universal movement, the connection being in the nature of a ball and socket joint thus insuring that the flat contacting face of the foot shall have an even bearing notwithstanding any irregularities in the floor with which it is adapted to engage. Furthermore, the construction is such that it is impossible to bind the ball and socket connection by reason 01"? an extreme pressure applied to the plunger, the foot member being resiliently held in proper position notwithstanding any actuation of the plunger.

The invention. will be more readily understood by reference to the accompanying drawings, wherein,

Fig. 1 is a front elevation of a device constructed in accordance with my invention;

Fig. 2 is a longitudinal sectional view through the device; and,

Fig. 3 is a plan view.

In the drawings it will be seen that I provide a housing or casing 10 of generally tubular form having attaching lugs 11, 12, by means of which the device may be secured to a door at its lower edge. The casing is provided with two transverse walls 13, 14:, which are apertured to accommodate the plunger 1.5. An expansion spring 16, mounted in the space between the two transverse walls,

surrounds the plunger and engages a pin 17,.

carried by the plunger. As a means for retaining the plunger in a desired position I provide a catch consisting of a plate 18, normally held in the position shown in the drawings by means of a short spring 19 and provided with a lug or projection 20, adapted to be inserted within an aperture 2i, ithin the back plate which forms a part of the casing. The operation of the plunger and the catch being well, known, will not be described in. detail.

The holding member or foot which 1 prefor to employ has a circular rubber member 22 suitably held within a flanged disc 23, to which is riveted a ball member 211. The ball is held within a. socket provided in the lower portion of a tubular member and engages a metailic disc 26, also carried within the tubular member. which disc rests upon an annular shoulder 27, so positioned that the space provided for the ball is just suflicient to insure contact between the ball and the disc. A coil spring 28 extends between the disc and the lower end of the plunger 15, the downward force exerted by the plunger being transmitted to the foot member through. this spring.

The lower end of the plunger is guided within the tubular member 25 by means of. the collar 29 and is held in proper relation to the tubular member by means of the transverse pin 30 which engages a slot 31 in the plunger and a slot 32 in the tubular member 25. A rubber washer 33 surrounds the plunger and is positioned between the upper end of the tubular member and the trans verse wall 13.

In operation it will be seen that a downward force applied to the plunger exerted against the spring- 28 thus causing the downward travel oi the tubular member and its connected parts to a point at which the rubber foot engages the floor. Any continued downward pressure applied to the plunger results in compressing the spring 28, as permitted by the pin and slot connections 30, 82. At this point it will be seen that the foot member is resiliently held against the floor and that if there are any irregularities in the floor the foot member may accommo date itself thereto by reason of: the ball and socket connection through the plunger. This insures, furthermore, a more secure holding action than would otherwise be pos sible. U 3011 arelease of the lun er it will retract to a slight extent until gripped by the catch 18 and this slight return move ment will. be permitted due to the slot 31 and without change in the position of the tubular member 25. WVhen the plunger and its associated parts are to be released a down- V ward force is applied to the catch 18 whereupon the spring 16 will cause the return of the plunger, the shock thereof being absorbed by the rubber washer 33.

Obviously the construction is capable of considerable modification and such modifications as are within the scope of the claims I consider within the spirit of my invention.

I claim: 7

1. In a door stop the combination of a casing, a plunger therein, a spring acting to resist downward movement of the plunger, a catch for the plunger, a tubular member in the lower end of the casing and separate from said plunger said member providing a socket, a foot having a ball to engage said socket, a spring between the lower end of the plunger and said foot, and a pin and slot connection between the plunger and the tubular member.

2. In a door stop the combination of a casing, a plunger therein, a spring acting to resist downward movement of the plunger, a catch for the plunger, a tubular member in the lower end of the casing and separate from said plunger said member providing a socket, a foot having a ball to engage said foot, said plunger and tubular member being slotted, and a pin connecting said members through said slots.
