Claims.

The present invention relates to improvements in door stops, and has particular reference to a stop that is adapted for holding a door in open position.

In making repairs on an automobile and servicing various parts thereof, such as the instrument board, transmission, battery, etc., it is quite desirable that the door of the automobile be maintained in open position, thus allowing the mechanic to gain access more easily to the different parts.

It is proposed in this connection to provide a stop, which may be readilyapplied in place for holding the automobile door open. It will, of course, be understood that my door stop is not to be limited to this particular use, and I will describe the stop with reference to an automobile door merely by way of illustration.

-An object of my invention is to provide a door stop, which is adapted to be fastened to one of the door hinges in such a manner that the stop will hold the door against closing until such time as the stop has been removed.

A further object resides in the provision of a door stop that will allow further opening of the door from an initial open position. The stop is made for automatically extending itself when the door-opening is widened so as to maintain contact with the door.

A still further object is to provide a door stop that will automatically lock itself against return movement in any position to which it may be extended.

Moreover, I propose to provide a door stop 35 adapted to be applied to the hinges on either side of the automobile or the like, and which will be firmly anchored in position after being attached thereto.

Other objects and advantages will appear as the specification proceeds, and the novel fea- 1937, Serial No. 166,993

Although I have shown only the preferred form of my invention, it should be understood that various changes, or modifications may be made within the scope of the claims hereto annexed without departing from the spirit of my invention. 5

Referring to the drawing in detail, I have illustrated a body post I having a door 2 secured thereto by means of a hinge 3 in the usual manner. The hinge comprises two straps 4 and 5., Which are journalled on a vertical pin, as at 6'. It will be understood that when the door is closed the faces 6 and I of the body post I and the door 2, respectively, contact one another. Figure 1 shows the door after it has been opened to a position at right angles to the side 8 of the automobile.

My door stop is indicated generally at 9 in the several views, and includes in its structural features a substantially T-shaped body member ID, having the arms ll of the T slotted, as at l2, for engagement over the hinge strap 4.

The stem I4 of the T-shaped body member extends through the space, which is defined between the body post and the door when the latter is opened, and in Figure 1 the stem is substantially parallel with the automobile side 8. The free end of the stem [4 has a squared opening I5 formed transversely therein for slidably receiving a rod I6, the latter also being square in cross-section. It will be understood that the opening I5 and rod "5 may be round, if desired.

In Figures 1 and 4, I show the rod It as having an enlarged head H, which is urged away from the stem M by means of a spring l8 working between the stem and the head. The latter abuts the face 1 of the door in the manner shown in Figure 1 in normal operation. Upon opening the door wider, the head is maintained in contact with the door by means of the spring I8, and the latter at all times prevents the stop from accidentally becoming disengaged from the hinge strap 4.

For holding the rod I6 against return movement in any position to which it may be extended, 1 form ratchet teeth l9 along the length of the rod, which are engaged by the pawl 20, (see Figure 4). The pawl is urged into the space between the teeth by means of a spring 2| interposed between the squared head 22 of the 50 pawl and a sleeve 23, the latter being threaded into the end of the stem l4.

A handle 24 may be manually retracted for disengaging the pawl from the ratchet teeth and thus allow the head IT to move toward the stem I4. The head 22 of the pawl may be guided in a squared guideway 22', if desired.

The rod It extends laterally from the stem at right angles with respect to the arms ll of the T, and a nut 25 limits the movement of the head I! away from the stem.

Having thus described the various parts of my invention, the operation of the door stop may be readily understood. The door 2 is first opened into substantially the position it occupies in Figure 1. The spring 18 is then compressed by moving the head I! toward the stem 14, and

the stop is placed in position by engaging one of the slots l2 over the hinge strap 4, (see Figures 1 and 2), with the head I! abutting the face of the door.

It is apparent that upon opening the door 2 further the head I! is maintained in contact with the door by means of the spring 18. The rod [6 moves to the right in Figure 1 as the door opening is widened, and the ratchet teeth l9 are free to move beneath the pawl 20. However the rod is held against return movement from any extended position by means of the pawl, unless the latter is first released by manually retracting the handle 24.

When the door stop is applied to the righthand door of the automobile, with the hinge arranged at the front of the door, the slot I2 is engaged over the hinge strap 4'. Upon applying the stop to the left-hand door, with a similar hinge arrangement, the stop is turned upside down and the slot I2" is used for anchoring the stop to the hinge strap.

I claim:

1. A door stop comprising a body member having means for anchoring the member to a hinge strap, and means on the member for abutting a door for holding the latter against closing, said last-named means being extensible when the door is opened wider, and means for automatically extending the door-abutting means when the door-opening is widened so as to maintain contact with the door.

2. A door stop comprising a body member having means for anchoring the member to a hinge strap, and means on the member for abutting a door for holding the latter against closing, said last-named means being extensible when the door is opened wider, and means for automatically extending the door-abutting means when the door-opening is widened so as to maintain contact with the door, and means for automatically locking the door-abutting means in any position to which it may have been extended.

3. A door stop comprising a body member having means for securing the member to a hinge strap, and a rod adjustable transversely in the member and arranged for abutting a door for holding the latter against closing, the rod having ratchet teeth thereon, and a pawl engaging the ratchet teeth for locking the rod against return movement after the rod has been extended fromthe member.

4. A door stop comprising a body member having means for securing the member to a hinge strap, a rod adjustable transversely in the member and having an enlarged head thereon arranged for abutting a door for holding the latter against closing, and a spring working between the member and the head for automatically maintaining the latter in contact with the door as the door-opening is widened.

5. A door stop comprising a T-shaped body member having slots in the arms of the T for receiving a hinge strap, a rod slidable transversely in the stem of the T at right angles to the arms thereof and arranged to abut a door for holding the latter open, and yielding means urging the rod against the door.
