DOOR sToP 4 Filed Jan. 5, 1956 Patented Sept. 29, `1936 UNITED STATES PATENT OFFICE Claims.

The invention relates to door stops, and has for its object to provide a device of this character which is constructed in a manner whereby it may be attached to the hinge of a door and without 5 modifying the construction of the hinge by simply removing the yhinge pin and passing the pin again through the hinge joint and an aperture in the device.

A further object is to provide a hinge carried door stop comprising a hinge pin receiving eye and door and door frame facing engaging members for stopping the door when it is swung open.

A further object is to provide a door stop comprising members hinged to the hinge of the door and extending outwardly from the hinge and into crossed relation and provided with adjustable door and door frame engaging members for limiting the movement of the door. Also to provide the members with notched slots through which securing means extends for positively holding the members in adjusted relation to each other.

A further object is to provide a door stop comprising outwardly extending hinged carried segmentally shaped arms having their outer ends in crossed relation and said arms being provided with adjustable stop elements and arcuate notched slots through which a clamping screw extends for positively holding the arcuate arms in adjusted positions when adjusting the stops carried by the arms to various positions.

With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawing:

Figure 1 is a view in elevation of the butt of a conventional form of pin hinge and portions of a door and door frame, showing the device applied to the hinge.

Figure 2 is a top plan view of the stop showing the door and door frame as well as the hinge pin in horizontal section and the door closed.

Figure 3 is a view similar to Figure 2, but showing the door in open position.

Figure 4 is a View similar to Figure 2, but showing the device applied to an inwardly set hinge butt.

Figure 5 is an enlarged top plan view of the outer ends of the arms, showing the securing bolt in position and between notches of the arms.

Figure 6 is a vertical transverse sectional view through the crossed ends of the arms showing the securing bolts.

Figure '7 is a horizontal sectional view through a modified form of door stop.

Referring to the drawing, the numeral I desig- 5 nates a conventional form of door, and 2 a portion of a door frame, both being of usual construction.

The hinge comprises leaves 3 secured by means of screws 4 to the door and door frame in the 10 usual manner. The hinge shown is of the conventional butt type wherein the leaves are provided with axially alined apertured knuckles 5, through which a removable pin E extends. The upper end of the pin 6 is generally provided with a flange head 'l for forming a finish and also for providing means to be gripped when removing the pin from the hinge. In the present device, the door stop is attached to the hinge in a manner whereby it will not be necessary to modify or change the construction of the hinge. It will be noted by referring to Figure 1 that the stop is supported on the pin 6 between the head 'l and the upper hinge knuckle 5.

The stop shown in Figures 1 to 6 inclusive comprises opposed arcuate shaped arms 8, the inner ends of which terminate in inwardly extending arms 9 having eyes I0, through which the pin 6 extends. By providing the arms 9, it will be seen by referring to Figure 4, that the arcuate arms 8 will be spaced outwardly from the hinged butt when the device is applied to an inwardly set hinge as shown in Figure 4; sometimes called a blind hinge. When so applied, it is obvious that the arms 9 will allow freedom of movement and maximum swing of the members during a door stopping operation. The outer ends of the arcuate arms 8 are in crossed relation and are provided with slots II, the outer sides of which are provided with plurality of notches I2, which receive 40 the opposite sides of the securing bolt I3 which passes therethrough.

By providing the notches I2, it will be seen that when the bolt I3 is tightened the arcuate arms may be adjusted to various positions in relation to each other and positively held against slipping when the door is swung open for the door stopping operation, and at which time the rubber stops I4 engage the door and the door frame 2. The rub- 50 ber stops I4 are carried by screws I5 which are threaded through lugs I6 carried by the arms 8, and are held in adjusted positions by means of lock nuts I'I threaded on the screws l5 and cooperating with the lugs I6. The lugs I6 may be attached t0 the arm 8 in any suitable manner for instance by spot welding, riveting or by stamping the same as a part thereof. Applicant does not limit himself in this particular.

Referring to the modied form shown in Figure '7; in this form the arm I 8 is provided with an eye I9 adapted to be received on the pin 6. The outer end of the arm is imbedded in a rubber member 20 and threaded through the rubber member is a screw 2 I. The screw 2| has its head extending through a metallic washer 22, which carries a rubber bumper element 23. Disposed between the washer 23 and the bumper member 20 are intermediate washers formed from resilient material and designated by the numeral 24. In this form the length of the bumper may be varied by intere posing different thicknesses of bumpers 24 between the washer 22 and the. bumper element 20. Otherwise the operation is the same as in Figure 2.

From the above it will be seen that a door stop is provided which is simple in construction, the parts reduced to a minimum, and one which may be applied to a conventional form of door hinge without varying the construction of the hinge.

The invention having been set for-thV what is claimed as new and useful is:

1. A door stop comprising cooperating arcuate arms carried by a hinge, means for attaching the outer ends of the arms together in crossed relation and door and door frame engaging stops carried by the arms.

2. A door stop adapted to be supported on a door hinge and cooperative with a door and a door frame, said stop comprising arms pivoted on the hinge, said arms extending away from each other and terminating in crossed portions extending towards each other, securing means extending through the crossed portions and door and door frame stops carried by said arms and forming means for limiting the movement of the door to open position.

3. A door Astop carried by a hinge, said door stop comprising oppositely extending arms, said arms terminating in inwardly extending arms in crossed relation, slots in the inwardly extending arms, the outer sides of the slots being recessed thereby forming lugs, a securing means extending through the inwardly extending arms and through the notches, and stop members carried by the oppositely extending arms.

4. The combination with a device as set forth in claim 3, of arms carried bythe inner ends of the oppositely extending arms and terminating in hinge pin receiving eyes.

5. The combination with a device as set forth in claim 3, wherein the oppositely extending arms are provided with lugs and the stops mounted on said lugs are adjustable thereon.
