DOORSTOP Filed NOV. 4, 1931 Patented Sept. 13, 1932 WILLIAM H. DURANT, OF READING, MASSACHUSETTS o nooRs'roP ii Application filed November 4, 1931. .Serial No. 572,955.

This invention relates to a door stop adapted to bear'on opposite sides of an open door and on a floor under the door, to coniine the es door against accidental movement from any 5, opened position. Y

The invention is embodied in improvements renderino' a stop of this character more desirable in certain respects than others hereto' sa fore provided. Y

Of the accompanying drawing forming a part of this specification Figures 1 and 2 show in perspective a door stop embodying the invention and a portion of Y a door, the door a shown by Figure 1 being called a high hung door, while that shown by Figure 2 is called a low hung door.

Figure 3 is a bottom View` of one of the feet shown by Figures 1 and 2. A

Figure e is a perspective View vshowin g the foot provided with studs and a loop.

Fi eure 5 shows in section one of the blocks shown by Figures 1 and 2 and a foot and loop constructed as shown by Figure 4.

Figure 6 is a side view showing one of the blocks provided with a clamping member, the neck connecting the blocks with another block being shown in section.

. Figure 7 shows one of the blocks in section on line 7 7 of Figure 6, the other block being shown in elevation. l Y y Figure 8 shows in perspective the clamping. member shown by Figures 6 and 7.

The same reference charactersjindicate. the

- same parts in all of the figures.

My impro-ved door stop is adapted for use with either a high hung doorv whose lower end may be an inch or vmore above the floor', or a low hung door whose lower end may be d lapproximately half an inch or less above the iioor.`

The stop comprises a pair of blocks 12 hav-- ing flat oblong faces arranged to bear on a iioor, lopposed inner sides arrangedv to face opposite'sides of a door, and a neck 14 rigidly attached to the blocks and spacing them apart with their inner sides substantially parallel with each other. The blocks and neck may be of cast metalcast in one piece7 or the blocks may be cast upon the end portions of a separatelyformed neck or otherwise united` thereto. n .y

' The neck 14 is formed toenter the space between the lower end of a high hung door M D l (Figure 1)y and a floorsupporting the stop, 55 so that the stop may be located on the floor at any desired distance linward from the swingingpedge ofthe door. ,Y Y f The neck Yis located atV one side of the lonn gitudinal centers of the blocks so that it constitutesone end of a door receiving'recess between the major portions of the,blocks,"and isadapted to-abutthe swinging edge of a low hung door D (Fig. 2) in said.r ecess,'sov 7 5 that although the neck cannot be located in the spacel under the door D', them'ajor portions of the block 12 may be located at oppof site sides of said door in position to oppose accidental swinging thereof. The neckfis movable inwardly under'a high hung door to locate, all portions of the blocks beside the doorasindicated by Figure 1, so thatthe blocks do not project from the yswinging edge of the door, and do not constitute an lobstruction at said swinging edge. y. To preventrattling contact betweenvthe sides of the door and the inner sides of the blocks 12 I provide said inner sides with'antirattling buffers arranged to Contact noise lessly with oppositesides of a doorvportion so between the blocks. `'Each buffer maybe one side of a loop 17 of elastic or other suitable material extending vertically across the mid length portion of the block sides, the loops being confined against edgewise `vdisplacementwby the blocks preferably by grooves 18 fo-rmed in* the upper'edges of the blocks. The buffers are formed to project'outwardly from the sides of theV blocks and prevent'conf` tact .of any portion of the blocks with the door.y j To cause a frictional engagement between the blocks and the floor I provide feet. 19 of rubber or other suitable .frictional matei rial united to the ends of the loops and bearing on and covering the bottoms ofthe blocks', said feet .being adaptedto frictionallyenf' gage a Vfloor and oppose movement of. the blocks thereon. The bottomsurfaces of said feet are provided with obliquev grooves 19a ifif forming oblique corrugations (Fig. 3) having flat faces bearing on a iioor. The oblique edges of said faces are longer than they would be if the corrugations were not oblique, and therefore have a more effective engagement with the floor.

Each foot and loop may be molded in one piece, or the ends of the loops may be united by vulcanization to opposite edges of the feet, the loops upstanding from the feet, and being normally contracted so that they may be stretched and allowed to spring into the grooves 18. The loops conline the feet against the bottoms of the blocks 12.

To additionally secure the feet 19 to the blocks I provide thekbottoms of the blocks with sockets 2O receiving stud ortions 21 of the feet, so that endwise and ec gewise displacement of the feet are prevented.

To enable the stop to engage both sides of doors of dierent thickness I may provide one of the blocks 12 with va clamping member movable relative to the block to bear on one side of a door andv clamp the opposite side thereof against the other block.

Said member preferably includesv a bell crank

lever including arms

24 and 28 and fulcrumed at 25 in arecess 26 in one block. The arm 24 has ay face 27 which is movable by an operator through the arm 28, to exert pressure on one side of a door as indicated by dotted lines in Figure 7. The face 27 is preferably of rubber adapted to frictri'onally engage the door, and has a tongue 29 entering' a groove 30 in the lever.

I refer to provide the loop 17 with verticalijy arranged beveledv edge faces 31 on one or both of its sides, thus preventing the formation of shoulders liable to catch on or interfere with a door when' the stop is being moved into engagement therewith. Although the faces 31 are requiredl only on the inner sides of the loops I prefer to provide them on both sides, because by sodoing I am enabled to apply the feet and loops to the blocks without taking care in locating beveled faces on the inner sides of the blocks.

I claim:
