T 0 all whom it may Gomera.'

Be it known that I, MICHAEL J. SASGEN, a citizen of the United States, and resident. of Chicago, in the county ot Cook and State of Illinois, have invented certain new and useful Im rovements in a Doorstop, of which the ollowin is a specication.

My invention reites to improvements in door stops -and has special reference to a stop adapted to prevent a door from being opened beyond a predetermined point.

The door stop of my invention belongs to the strut rather than the plunger class and the object of my invention' is to provide a strut-like door stop which shall be efficient in its action, in which the strut lever shall be capable of being lifted from its operative position without the neceity of stooping down to engage the lever, and which device shall .be provided with means for retaining the strut in inoperative position.

As my improved stop is adapted to interior use upon highly nished doors, I have arranged simple means for preventing the strut frpm swinging against the. door and possibly marring it whenswung to its inoperative position.

A further feature of my invention relates to simple means for covering the pvoted floor engaging end of the lever with a suitable rubber covering and also for encasing in rubber, the projections which are adapte to be engaged by the foot of the operator when lifting the lever from operative position. f

My invention will be more readily understood by reference to the accompanying drawings forming part of this specification, and in which 4 Figure 1 is an elevational view of the device shown in full lines in operative position on a door, the swinging strut shown in inoperative position in dotted lines;

Figure 2 is a side elevation of the device as shown invFigure 1; Figure 3 is afragmentary vertical section on the line 3 3 of Figure 2;

lFigure 4 is a fragmentary side elevation of t 4e lower end of the strut, the rubber cas# ing being shown'in'sectionj; i

Figure 5 'is a'horizontal sectional view on the line 5-5 of Figure 2; Figure 6 isa detail section on the line 6-6 of Figure `1 showing a modified form of strut stop; and y 49 between them when 'of the toe of the shoe of the Figure 7 is a similar view showing another modified form of strut stop.

In said drawings, 1 represents a vertical, swinging door upon which the device is adapted to be mounted. The device'comprises a sheet metal bracket 2 consisting of an elongated base plate 3 having lateral projections 4 adjacent toits upper end perforated for receiving fastening screws 5 and the lower end 6 of the base bein perforated for receiving a fastening screw Between its ends the bracket is provided with two upturned ears 8 which are adapted to project out at right angles to the base and are spread apart to receive one end of a swinging strut 9 between them. The strut is fastened between the ears 8 by a riveted pivot 10. The bracket is placed upon the door 1- at such a height that when the strut is swung down it will contact with the Hoor when in a position inclined upwardly and inwardly toward the door sol as to brace the movement in one direction.

The upper end of the base is provided with two lateral projections 11 which are formed up at vright angles to the base,` their outer ends 12 being arranged parallel with each other and spaced apart to receive the Strut swung to vertical u standing position. The projections 11 have Suiiicient resiliency and are so related that when the strut is pushed between them they engage the strut with sufficient pressure to hold it in its vertical position.

At the lower end of the strut I provide a shoe 13 preferably formed up from sheet metal to provide a relatively `wide base 14 and lugs 15, the two lugs being adapted to straddle the lower end of thestrut" 9 and adapted to' be vpivotally mounted on the lower end of the 4strut bly; a riveted p-ivot 16.

The upper ends of t e lugs 15 are provided with extensions 17 bent to project laterally to form lifting lugs so that when it is desired to lift the strut from operative position it can be freed from the floor by the use j operator and when freed from the floor can readily be swungto inoperative position 'by the foot. The shoe 13 has a slight pivotal movement to allow it to engage the floor with sufcient holding pressure without sliding, the pivotal movement being limited by the extreme lower end 18 of the strut which, as shown in Figure 2 in dotted lines, engages the bottom door against plate 19 of the shoe 13 and prevents it swinging beyond a limited extent.

To provide friction between the shoe and the floor I preferably cover the shoe with a rubber envelope 20 Jforming the lower surface of the envelope into blunt transverse teeth 2l and curving the lower surface slightly in the direction in which the shoe swings, this for the purpose of obtaining good contact with the oor. I preferably make the envelope 20 to t around the lower part or base of the shoe and provide it with an opening 22 in its top by which it can be readily placed in position on the shoe, the resiliency of the envelope and the tapered shape of the lower part of the shoe serving to retain the envelope in position once it has been placed thereon. 'In some instances I prefer to vulcanize the envelope in position on the shoe.

To prevent the marring o'f the shoe of the operator by the projections when lifting the strut, I preferably coverthe projections 17 with rubber envelopes 23 which may be retained upon said projections in 'any suitable manner such as vulcanizing them inl position.

To prevent ,the marring of the door by the strut/when raised to inoperative posltion I provide means on the base to prevent the contacting of the shoe or the strut with the door. This means as illustrated in the drawings preferably consists of a projection 24 preferably integral with the base and arranged to contactwith the strut between its ends when swung to inoperative position. This projection as shown is struck up out of the base in the base forming operation being consequently easily and cheaply produced. Under some conditions of use it is desirable to have a cushioning stop for the strut as it is raised to inoperative position and for this purpose I may either cover the stop 24 with a rubber envelope 25 or I may provide a solid rubber stop 26 secured in some suitable manner to the base plate 2 such as by means of a screw 27.

I do not herein specifically claimthe rounded or curved bottom surface of the shoe such bei-ng claimed in my companion application Serial Number 534,287.

As man modifications of my invention will readlly suggest themselves'` to one skilled in the art, I do not limit or confine my invention to the specific details of construction herein shown and described.

I claim: Y
