NORMAN B, HUBD, OF NEW BRITAIN, CONNECTICUT. ASSIGNOR TO THE AMERICAN HARDWARE CORPORATION, on NEW BRITAIN, CONNECTICUT, ,A' CORPORATION on coNNRo'rIo 'r.

Y Application filed June 22,

To all whom it may concern:

Be it known that I, NORMAN B. HURD, a citizen of the United States of America, residing at New Britain, Hartford County, Connecticut, have invented a new and useful Door-Holding Device, of'which the following is a specification.

My invention relates to a holding device for swinging doors, the purpose-of the same being to hold the door open at an angle, so as to preye'nt it from being closed accidentally as by a gust of wind. Such devices are of particular'utility on doors for stables and garages,- where, if the door is not properlyheld while the carriage or car is entering or leaving, said door may be swung against the car to the injury thereof.

The object of my invention is to provide certain improvements in such devices, including a novel cushioning device to reventstraining the parts should the door be rapidly opened or should thedoor be subjected to heavy wind pressure on either side while open.

In the accompanying drawings I have shown my invention in a preferred form, in

' which- Figure 1 is a perspective view ofa portion of the door and door casing, with my new holder in place, the door being held Fig; 2 is a plan view thereof; 1

1 represents a swinging door hinged at 2 to the side 3 of the door casing. 4 repre- "sents the top of said door casing. The door holdingldevice itself comprises a rod or bar 5, preferably of relatively thick, flat stock. This bar is hung at one end on a stud 6 carried by a bracket 7, which is secured to the door 1. Preferably the stnd is on the under side of the bracket so that the barwill be Specification of Letters Patent.

normally supported at one end on the head of said stud. The stud passage through the bar is sufliciently large, and the length of the stud is such, that said bar may be easily tilted or rocked thereon. on an axis extending longitudinally of the bar in the manner and for the purpose hereinafter described.

I The latch and buffer mechanism is located at the free end of the bar. The latch comprises what is in effect a downwardly extending tooth 8, the edge of the tooth being beveled on the side toward the stud 6. The other edge is abrupt, to form a holding shoulder. It will be noted that this tooth is located at one side of the bar 5, so that, as the bar is rocked, the said latch tooth will rise and fall. 9 is an abutmentrwasher mounted on the bar 5 just beyond the latch tooth 8. 10 is the base of what I may terma stationary locking abutment. This base may be secured by screws to the top 4 of the door casing. One edge of this base 10 is turned downwardly and is provided with a slot or passage through which the bar 5 freely slides. The depth of the passage is suflicient to afford full clearance for the latch tooth 8, while the width of said slot is sufficient to allow the rod to slide therethrough freely even when turned at an angle thereto, as shown in Figs. 3 and 4/ The lower edge of the slot or passage through which the bar passes is formed on an incline, as shown in Fig. 9, so that the normal locking position of the bar willbe tilted somewhat.

11 is a chain, which is connected to the bar between the stud 6 and the latch tooth 8. This chain hangs over the edge of the bar on the side opposite said tooth (see Fig. 4). A downward tug on the chain rocks the bar 5 on a longitudinal axis in such a manner as to lift the locking tooth 8 so that it will be disengaged from the stationary look I Patented July 4, 1922.

form shown the abutment 9 is in the form of a plate mounted to slide on the extension 5. Betweenthe lug 15 and the abutment 9 is a coil spring 16, which holds the abutment plate 9 firmly against the main body of the rod 5 at the base of the extension 5. 17 is a nut or stop of any suitable form on the outer end of the extension 5. 18 is an upstanding flange on one side edge of the slide 14. The latch tooth 8 is formed by bending downwardly the opposite side edge of the slide 14. 19 is an upstanding flange on the side of the slide 14 beyond the latch tooth 8. -The forward edge of this flange 19 is preferably slightly beveled, said bevelb eing located in advance of the abutment 9. The abutment 9 extends above and below the slide sufficiently far so that it can never pass throu lithe slot in the stationary abutment carrie by the overhead portion 4 of the door casing. It will be noted that the studdQ normally stands in the forward end of the slot in the slide 14, being held in that position by the action of the spring 16, which tends to push the slide against the stop 17 Having thus described the various parts,

I will now set forth how the device operates.

If the door 1 is swung open rapidly and no effort is made to check the same manually, the rod 5 will slide rapidly through the stationary abutment until the abutment plate 9 encounters the fixed abutment. Since the abutment 9 is in reality supported by the coil spring 16, it follows that the shock will be received and cushioned by the spring a through the medium of said abutment9, the

spring compressing suflicientl to relieve the shock on the parts of the ho der, as well as on the door hinges. If the door is allowed to stand open and a heavy gust of wind strikes the doorso as to tend to move the same in an opening direction, the buffer spring will, through the medium of the plate abutment 9, operate as before, but assuming a gust of wind suddenly strikes the opposite side of thedoor, the buffer spring will operate to check the shock thereof, since this strain will tend to cause the bar 5 to move'on the slide, carrying the abutment plate 9 with it, thereby compressing the spring, the slide itself being-held against By this means it will be seen that a. single coil spring is capable of receiving and relieving-strain on the open door in elther direction.

It will be noted .that while the several parts are exceedingly simple and may be very cheaply and rapidly produced, they are, nevertheless, few in number and of such design as to possess great durability. They likewise are capable of being assembled very easily.

7 While I have shown the invention in its preferred form, manifestly various changes and modifications may be made without departing from the spirit of the invention or the scope of the following claims.

What I claim is:

1. A door holder comprising, a bar adapted to be pivotally connected at one end to a door, said bar being rockable on its own longitudinal axis, an abutment having a passage therethrough for said bar and adapted to be carried by an overhead portion of a door casing, a latch device on said bar at one side of the longitudinal axis of the same and arranged to detachably engage a portion of said stationary abutment when said bar is in one position, a buffer device, and means for rocking. said bar on its longitudinal axis to disengage said latch from said stationary abutment whereby said rod maybe moved longitudinally through the abutment passage.

- 2. In a door holder, a rod adapted to be secured at one end to a door. a stationary abutment having a passage therethrough for said rod, said abutment being adapted to be 'secured to the overhead portion of a door casing, a latch for inter-engaging said rod with said abutment when the door is open, and a single double-acting buffer spring cooperating directly with said latch and bar.

3.
