To all whom it may concern:

Be it known that we, HENRY G. VOIGHT and NORMAN B. HURD, citizens of the United States, residing at New Britain, county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Door-Controlling Mechanism, of which the following is a full, clear, and exact description.

Our invention relates to improvements in door holders, the same being of particular utility when combined with a door closing mechanism, the preferable form of our invention being shown in the accompanying drawings, in which- Figure 1 is a plan view showing our invention as employed with a door closer. Fig. 2 is a side elevation partly in section. Figs. 3, a, 5, 6 and 7 illustrate like details in different positions. Fig. 8 is a View of the under side of the arm shown in Fig. 1 with parts of our invention applied thereto. Figs. 9, 10 and 11 are detail views.

1 represents the main body or case of a door closer of any suitable construction.

2 is the door closer arm.

34567 are stop members designed to cooperate with other parts of the stop mechanism hereinafter described to hold the door closure arm 2 and thereby the door in an open position.

It'may be assumed that the door. closure arm 2 is in approximately that position in Fig. l in which it would appear when the door is closed. If the arm 2 is swung on its axis 2 clockwise, as by the opening of the door, it is the intention that said arm shall be stopped at approximately the position in dicated by the stop members 845. If the arm 2 is swung counter clockwise, it is the intention that the stops 765 shall 00- operate with said arm to hold it in a position in which the door will stand ajar to the desired degree, depending upon the stop encountered.

That part of the stop mechanism designed to cooperate with the stop shoulders 3 to 7 inclusive, and to which we have previously referred, is carried by the arm 2 and-comprises a pendulum or stop-engaging member 8, the same being yieldingly carried by the arm 2 as by a spring pressed tilting lever, pivoted at 10, to the arm 2.

11 is a spring carried by the arm 2 and engaging the lever 9 to hold the lever normally in such a position as to cause the pendulum 8 to properly engage with one of the stops 3 to 7 inclusive to hold the arm 2 in the open position. The distance from the pivotal center of the pendulum 8 to the stop member on each of the stops 8 to 7 is such that when the end of said pendulum engages one of said stop members, said pendulum will incline downwardly and forwardly at an angle, thereby blocking the advance of the arm 2.

To illustrate, in Fig. 3 we have shown the normal inactive position of the pendulum 8. If the arm' 2 is moved to the right, the end of the pendulum will be dragged over the stop 7 (Fig. 3) until it assumes the position shown in Fig. at, in which position the lower end of the pendulum rests against the stop shoulder 7 of the stop 7. In this position it will be seen that the tendency of the closer to swing the arm 2 back to its normal position will be resisted. When it is desired to release the door to permit it to close, the door may be opened so that the arm 2 will be moved still farther to the right (relatively to the position shown in Fig. 4) until the pendulum 8 entirely clears the stop 7, whereupon it will be droped to the position shown in Fig. 3, so that as the arm 2 moves back to the normal position the pendulum 8 will freely swing and ride over the stop 7, as indicated in Fig. 5. If any one unfamiliar with the stop mechanism should attempt to close the door with the pendulum 8 in the position shown in Fig. 4, this could be done without danger of breakage to any of the parts since it will be remembered the pendulum 8 is carried on the end of the tilt ing lever 9 hence when pressure is applied in a direction to close the door sufficiently to overcome the action of spring 11, the lever 9 will tilt so that the pendulum will be elevated bodily on the stop 7 (see Fig. 6) until it passes the stop 7 to permit the arm 2 to be restored to its normal position. It will thus be seen that there is no danger whatever of breakage of any of the parts by reason of the operation of the mechanism by those unfamiliar with its construction.

It will be seen that this type of door stop possesses many advantages over the ordinary spring friction stop such as associated with a spring closing device, in that in our present improvement a series of fixed stop abutments may be provided to enable the door to be held open at any one of many angles, and when released therefrom to freely close. In the ordinary spring friction stop, as applied to a door closer, it is possible to open the door and stop the same at only one point, because if a plurality of stop shoulders were employed for separate engagement by the spring friction device, the spring friction device would have to be manually forced over each one of said abutments successively in the closing operation, whereas in the present device the pendulous stop engaging member 8 will freely drag over each shoulder (after being released from one) by the action of the closer spring alone.

From the foregoing it will be readily understood that this improved stop, by reason of its difference in construction and mode of operation, is substantially and materially different from the ordinary spring friction stop, such as applied to spring closers in the past. In this respect the operation of the device while the door is closing corresponds broadly to the operation of the door stop made the subject-matter of co-pending application Serial No. 528,058, filed November 15th, 1909, by H. G. Voight, one of the joint inventors herein.

It will be understood that various stops 3 to 7 are constructed in a generally similar manner and only modified for right and left hand action, as already indicated, and in the particular form shown, the stop 5 is adapted for either action. \Vhile we have shown only five stops in all, obviously the number of said stops may be changed as desired to provide as many holding shoulders for pendulum engagement as the exigencies of any particular case demand or make desirable.

It will be understood, of course, that we have attempted to show herein only the preferred form of the construction and that we anticipate that modifications may be made in the various details and arrangement without departing from the spirit and scope of the invention.

What we claim is:

1. In a door stop mechanism, a stationary part, a movable part, a stop abutment carried by one of said parts, a cooperating stop engager carried by the other part, said stop engager being pivoted to swing like a pendulum, the pivot of said stop engager being adapted to yield.

2. In a door controlling mechanism, in combination a movable door closing member, a relatively fixed member, cooperating stop members carried by said parts, one of said stop members being pivotally mounted and arranged to swing, and a yielding support for one of said stop members.

3. In a door controlling mechanism, in combination a movable door closing member, a relatively fixed member, cooperating stop members carried by said parts, one of said stop members being pivotally mounted and arranged to swing, and a yielding and spring pressed support for one of said stop members.

. 4. In a door controlling mechanism, in combination a movable door closing member, a relatively fixed member, cooperating stop members carried by said parts, one of said stop members being pivotally mounted and arranged to swing, and a spring pressed tilting lever supporting said last mentioned member.
