DOOR-GPERATING MECHANISM.

Application filed September 18, 1916.

To all whom it may concern:

it known that 1, Emmy C. UMPLEBY, a citizen of the United States, residing at Angelica, in the county of Allegany and State of New York, have invented new and useful Improvements in Door-@perating Mechanism, of which the following is a specification.

This invention relates to door operating mechanisms adapted to be used on the bodies of automobiles and similar vehicles, and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide mechanism of the character stated which is of simple and durable arrangement of parts and which includes a manually operable lever adapted to be used for working a latch device and for swinging the door.

Another object of the invention is to provide in a mechanism such as stated, features so arranged that the bolt of the latch device is moved to a retracted position at the initial movement of the mechanism thereby releasing the door, and the door is swung during the final movement of the mechanism. Also provision is made whereby the parts may be set so as to leave thedoor free to be swung without the use of the lever.

In the accompanying drawings Figure 1, is a side view of an automobile with parts broken away showing the mechanism applied;

Fig. 2, is a fragmentary sectional view of the same showing the door operating mechanism in section;

Fig. 3, is a perspective View of the door operating mechanism detached and showing some of the parts disconnected;

- Fig. A, is a detailed sectional view taken on the line H of Fig. 2.

As illustrated in the accompanying drawings the mechanism is shown applied to the body of an automobile, but it is to be understood the device may be applied and used to advantage on the bodies of other kinds of vehicles.

The vehicle body 1 is provided at its side with the usual door opening 2 and a door 3 is arranged to fill in and close the said open ing. The door 3 carries at one side edge arms 4 which are fixed to a vertical shaft 5 journaled in or to the side of the body 1 beyond one edge of the door opening 2. A crank 6 is fixed to the lower end of the shaft Patented Apr. 17, 1917.

5 and is located below the floor of the body 1 as best shown in Fig. 2. A keeper 7 is mounted at the free edge of the door 3 and a guide 8 is located in the stile 9 which delines that edge of the opening 2, which receives the free edge of the door3 when the same is moved to a closed position in the door opening 2. A latch bolt 10, is slidably mounted in the guide 8 and is provided with a beveled end adapted to enter the keeper 7 when the door 3 is in a closed position in the door opening 2, whereby the door is secured in closed position.

A bar 11 is pivoted at its upper end to the side of the body 1 at a point above the guide 8, as indicated at 11 and carries at an intermediate point a pin 12 which is slid ably rcceivecl in a slot 13, provided at the inner end of the bolt 10. A collar 14- is adjustably mounted on the bar 11 and is held at an adjusted position thereon by a set screw 15 in the usual manner. A flat spring 16 is carried by the collar 14 and bears at its upper portion against a side pin 17 carried by the bolt 10. The spring 16 is under tension with a tendency to normally hold the bolt 10 in a projected position in the guide 8., and one end of the slot 13 in contact with the side of the pin 12. The lower portion of the bar 11 passes through an opening 18 provided in the floor of the body 1.

A rod 19, is pivotally connected at its rear end with the lower end of the bar 11 as shown at 19 and at its forward end the rod 19 is pivotally connected with the rear end of a rod 20. The rod 20 is provided at a point adjacent its rear end with a slot 21 which receives the pin 6 of the crank 6. A pin 22 passes through the end portion of the crank pin 6 which lies below the rod 20 and serves to hold the said rod up in position on the crank pin.

The forward end of the rod 20 is pivotally connected with a yoke 23, and the said yoke in turn is pivotally connected with the lower end of a hand lever24. The said lever is fulcrumed upon the floor of the body 1 and passes through an opening therein as shown in Fig. 2. A segment 25, is mounted upon the floor of the body adjacent the lever 24: and is provided at its upper edge with spaced notches 26. A spring pressed pawl 27, is slidably mounted on the lever 24: and is adapted to engage in the notches 26 of the segment 25.

7 lows: With the parts in the positions shown in full lines in Fig. 2, the bolt 10 is in a projected position and its end is received in the keeper 7 and the door 3 is locked in a closed position. When the pawl 27 is withdrawn from the rear notch 26 and the upper end of the lever 24 is moved in a forward direction to the position shown in dotted lines, the rod 20 is moved rearwardly and the slot 21 moves along the crank pin 6 without turning the shaft 5. The rod 19, however, moves rearwardly simultaneously with the rod 26 and swings the lower end of the bar 11 rearwardly, whereby the bolt 10 is withdrawn or retracted from the keeper 7 Thus the door 3-is freed and may be swung by hand and at will from a closed to an open position and vice versa. Therefore it will be seen that the initial movement of the lever 72% and the parts connected therewith does not move the door 3 but serves merely to move the latch bolt 10 to a retracted position.

. When the upper end of the lever is moved forward to an extent which will permit the pawl 27 to enter the forward notch 26, the forward end of the slot 21 comes in contact with the crank pin 6 whereupon the shaft 5 is turned and the door 3 is swung from a closed to an open position.

When the upper end of the lever 24L is swung rearwardly the end of the bolt 10 is projected into the path of movement of the keeper 7 and as the door 3 swings to a closed position, the keeper strikes the beveled end of the bolt 10 and the bolt is moved longitudinally against the pressure of the spring 16, and the slot 13 moves along the pin 12.

When the socket of the keeper comes into alinement with the bolt 10 the latter is shot forward by the spring 16 and is caused to enter the keeper, whereby the door 3 is secured in a closed position in the door opening of the body.

From the foregoing description taken in conjunction with the accompanying drawings it will be seen that a door operating mechanism of simple structural arrange- Inent is provided and that the same may be operated and controlled by one occupying a forward seat of a vehicle to open and close a door positioned at the side of the vehicle body at a point behind the operator's seat.

1. In combination with a body having a door opening, a door mounted for swinging movement at the opening, a latch bolt mounted for movement on the body and adapted to engage the door, a bar pivoted on the body and having a pin and slot connection with the bolt, a spring interposed between the bar and bolt, and a lever operated mechanism connected with the door and the bar 2. In combination with a body having a door opening, a door mounted for swinging movement at the opening, a latch bolt mounted for movement on the body and adapted to engage the door, a bar pivoted on the body and having a pin-and-slot connection with the bolt, a collar adjustably mounted on the bar, a spring carried by the collar and engaging the bolt, and a lever operated mechanism connected with the door and the bar.

In testimony whereof I aliix my signature.
