DOOR STOP AND HOLDER.-

Specification of Letters Patent.

Patented May 1, 1906.

Application filed Sept ember 6,1904. Serial No. 223,358.

To all whom it may concern:

Be it known that I, AXELF. LIFVENDAHL, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of, Illinois, have invented a certain new and useful Improved Door Stop and Holder, of which the following is a description.

My invention relates to means for preventing a hinged or pivoted door from being opened beyond a certain fixed point in combination with means for holding the door open to that fixed point when desired.

The object of my invention is to produce a device of the kind described simple and eifective in construction and operation and capable of withstanding the rough treatment such a device is subjected to in general service, and in which the adjustment required when the device is to be employed as a doorholder may be made by a simple movement of a part or parts of the device which will cause it to operate to hold the door open when next the door is opened to its limit of move-.

ment.

A further object is to provide a device neat and attractive in appearance and one which will not mar the adjacent woodwork or glass nor form a permanent obstruction upon the floor or walk and firmly hold the door open novel construction, arrangement, and

when employed for that purpose.

To this end my invention consists in the combination of parts herein shown and described, and more particularly pointed out in the claims.

In the accompanying drawings, wherein like or similar reference characters indicate like or corresponding parts, Figure 1 is a plan view of my device with a portion broken away to more clearly show the construction.

Fig. 2 is an'elevation of my device. Fig. 3 is.

a sectiontaken substantially on line 3 3 of Fig. 1. Fig. 4 is an enlarged section of the locking portion. Fig. 5 is an enlarged perspective view of a detail. Fig. 6 is a perspective view of a door and its frame with my device in operative position when the door is open. Fig. 7 is a section taken substantially on line 7 7 of Fig. 6.

In the preferred form of my device shown in the drawings, 1 is a bracket adapted to be attached to the upper end of a door 2 in any referred manner. The arms 3 and 4 are 'nged together at 5, and each arm at the hinge may be provided with a shoulder 6 6, so arranged as to abut to prevent the adjaengagement with the part 8.

cent ends of the arms moving to any extent beyond the center line when the device is operated very rapidly. The free end of the arm 3 is suitably formed to engage with the bracket 1 to form a hinged connection and thereby attach the arm to the door, while the free end of the arm 4 is formed to be engaged with a head 7 to attach that arm to the head-casing or other convenient parts of the door-frame.

In the construction shown in the drawings a circular portion 8 is formed u on the end of the arm 4, adapted to beheld etween the parts 9 and 10 of the head 7 by the bolt 11 passing centrally through the part 8 and arranged to hold the parts 9 and 10 in suitable relation therewith by means of the nut 11*. Preferably an annular recess is formed in the adjacent faces of the parts 8 and 9 and a helical spring 12 arranged within this recess with its ends engaged, respectively, with the parts 8 and 9 in such positions that when the device is in position upon a door the spring 12 tends to normally hold the arni 4 in the position shown in Fig. 1 or in the position they occupy when the door-is closed. this specification where I refer to the arms as closed it is to be understood as indicating the ab ove-described position. To strengthen my device and prevent the bolt 11 frombending, I provide a semicylindrical flange 14 upon the head 7 and secure the part 10 to this flange against lateral movement by suitable pins or screws. The flange 14 also serves as a convenient means for supporting the sleeve 15, containinga sprin -actuated pi n 16, arranged to engagea suita le recess 17 1n the periphery of the part 8 when my device to be employed to hold the door open. Preferably on one side of the sleeve 15 I pro vide a longitudinal slot 18, withashort lateral extension 19 at its outer end, and arrange a stud 20 upon the pin 16 and projecting into the slot. When it is desired to use my device as a door-stop only, the in 16 is drawn outward by means of a suitab e knob 21 until the end of the pin clears the opening in the part 8 and the stud 20 is in position to enter the lateral slot extension 19, when by partially rotating the pin the stud will enter the slot extension and prevent the spring 22, preferably arranged within the outer end of the sleeve 15 and engaging the enlarged head of the pin 16, from returning the same into Preferably when attaching my device to a door it should be so positioned and arranged that when the pm 16 is in engagement with the recess 17 in the part 8 the center of the hinge 5 will lie in line with the centers of the hinges at the other ends of the arms, thus practically relieving the-pin 16 from all strain, except that caused by the tension in the spring 12, regardless of the pressure upon the door tending to close the same.

It is evident that while I have described the preferred form of my device that the construction may be modified in a number of Ways without changing its general operation.

or example, it is obvious that the spring 12 may be arranged upon the bracket 1 or at the hinge 5, if preferred. The head 7 may also be modified in a variety of ways to better adapt it to particular conditions or cheapen 1ts construction, and in some cases it may be desirable to attach the head 7 to the door and the bracket 1 to the casing or adjacent parts.

What I claim as new, and desire to secure by Letters Patent, is-

1. A device of the kind described, com prismg a pair of pivotally-connected arms, each arm provided with means for pivotally attaching its free end to one of two objects united by a hinged connection thereby when said arms are extended limiting the action of said connection, in combination with resilient means tending to normally hold the arms partly closed.

2.
