Application filed August 1, 1919. Serial No. 314,702

To all whom it may concern Be it known that I, HENRY G. VoroHT, a citizen of the United States of America, residing at New Haven, Connecticut, have invented a new and useful Door-Holder, of which the following is a specification.

My invention relates particularly to a device intended to engage automatically when the door is opened so as to hold the door against rattling and yet which may be released by a direct pressure against the door when it is desired to close the door.

The main object is to provide a construc tion which can be made and assembled readily at reasonable cost and which will operate with certainty and yet which is not likely to get out of order.

In its preferred form the invention contemplates the use of two members especially constructed to cooperate as hereinafter more fully set forth. One member has a pivoted latch adapted to be secured to the door and so constructed as to be automatically held in position for operation. The other member has two parts secured together in a housing namely, a bracket having a catch shoulder and a releasing shoulder for cooperation with the latch and a spring pressed plunger which presses against the door so as to hold the parts of the latch in engagement with the catch shoulder and prevent the door from rattling and also serving to push the door away when the latch is retracted.

Figure 1, is a view showing the two members attached to fragments of a door and a wall, part of the latch member being broken away. In this figure the parts are shown in the position with the door open and the latch engaged in the holding position.

Fig. 2, is a similar view but with the housing, plunger member and bracket partially in section and the parts in the position they occupy when pressure has been applied to the door to release the latch.

Fig. 3, is a plan view of the parts in the position of Fig. 1.

F 4, is an end view of the relatively stationary member.

The latch has a hook portion 5 extending downwardly with its engaging shoulder facing toward the door and an inclined shoulder facing a stationary support. This latch is hinged at 6 between two lugs 7 carried by a plate 8 which is secured to the door 9 in any suitable manner. The latch has a shoulder 10 adapted-to rest against the abutment 11 so as to support the latch in position ready to engage the other member.

The hook is adapted to interlock with the stationary shoulder 12 when the parts are in the position as shown in Fig. 1 with the door open. A stationary abutment 13 is provided adapted to engage the. shoulder 14- on the latch when the door is pushed toward the abutment 'so that in this movement the latch is swung or tilted on its pin 6 and its hook raised and disengaged from the stationary shoulder 12 as shown in Fig. 2. The plate 8 may be provided with a shoulder 15 to act as a stop for the latch in the releasing action. The parts of the latch are so designed and arranged that gravity tends to hold the latch in the position of Fig. 1. l

The plunger 16 is guided in the housing 17 which is secured to the support 1.8 in any suitable manner. The rear of the plunger 16 may be recessed to receive the helical spring 19 which presses the plunger outward. shoulder 20. to limit its outward movement and may be guided by a part 21 in the housing as well as by the walls of the opening in the front of the housing through which the plunger projects. i

For convenience in manufacture and as-- semblage the latch shoulder 12 and abutment 13 are preferably formed in the horizontal member of an Lshaped bracket 22, which is positioned in the housing by shoulders 23 and held by the flanges 24 and 25. The vertical part of the bracket 22 serves as an abutment for the spring 19. By this construction to assemble the parts it is simply necessary to first insert the plunger into the housing with its spring and then insert the bracket from the rear, thus compressing the spring and then securing the bracket and housing together.

When the parts of the device are installed and the door is latched in the open position of Fig. 1, it is necessary in order to disengage the latch to simply press against the door so that the abutment 13 pushes back the latch in the position shown in Fig. 2. As will be clear from Fig. 2 the slot in the abutment 13 in which the hook portion 5 engages is elongated. There is an appreciable distance between the abutment 13 and the shoulder 14 constituting lost motion between the parts so that when the door The plunger is provided with a is pushed toward the abutment the hook member 5'slides in the slot until the shoulder 14 strikes the abutment sharply and the hook 5 is suddenly jarred out of the slot. If the pressure on the door is then removed, the spring pressed plunger 16 will push the door and latch away before the hook on the latch can again drop into engagement with the shoulder 12. A slight pull on the door at the releasing moment will of course facilitate the complete release even in case the spring 19 is not sufficiently strong to materially assist.

In opening the door it is simply necessary to push it back until the beveled or inclined face of the latch engages the end of the abutment 13 which will raise the latch and allow its hook to ride along the upper surface of the bracket and drop down into engagement with the shoulder 12. The parts are so proportioned that just before the latch and shoulder 12 engage, pressure is applied through the plate 8 against the plunger 16 so as to compress the spring 19 and thus produce tension between the parts which will keep the door from rattling.

I claim:

1. A door holder comprising, an L-shaped latch member pivoted on one arm and having a catch shoulder on the other arm, a stationary member having a catch shoulder adapted to be interlocked with the shoulder on the latch member and having a releasing shoulder for engaging the pivoted arm of said latch member.

2. A door holder comprising, an L-shaped latch member pivoted on one arm and hav ing a catch shoulder on the other arm, a stationary member having a catch shoulder adapted to be interlocked with the shoulder on the latch member and having a releasing shoulder for engaging the pivoted arm of said latch member and a spring pressed member for yieldingly pressing the door away from the support and holding the'catch shoulder in positive locking engagement.

3. A door holder comprising, a housing, a plunger mounted to slide in the housing, a bracket member secured to the housing, a spring interposed between said plunger and said bracket member and said bracket member having a catch shoulder, and a pivoted latch member adapted to interlock with said catch shoulder, and to be held in interlocked position by said plunger.

4. In a door holder, a housing, a plunger guided therein, a bracket rigidly secured to said housing, a spring interposed between a part of said bracket and said plunger, said bracket having a catch shoulder and a releasing shoulder, a latch member for cooperation with said bracket, said plunger serving to hold said latch member and bracket in cooperative engagement. 7

5. In a door holder, a member formed of two parts, one part having a catch shoulder and a releasing abutment stationary with relation thereto, a plunger guided to move in the other part, the rear of said first mentioned part being separable from the part which guides said plunger, a spring interposed between said separable part and said plunger, and a latch member adapted to coact with said catch shoulder, said latch member and said catch shoulder being held in co-acting engagement by said plunger and said spring;

6. In a door holder, a member having a catch shoulder, a latch member adapted to engage said catch shoulder, an abutment normally spaced apart from said latch memher and adapted to contact with said latch member to suddenly jar the latter out of engagement with the catch shoulder when the door is moved in one direction.
