LAURENCE SCHOMO, OF sAYnE, rnnnsynvnnrn.

noon-HofDEni To all whom it may concern:

' Be-it known that I,-LAo1 n-NoE L. Sonouo, a citizen of the United'titates', residing at Sayre, in the county of Bradford and State of Pennsylvania,have invented certain new and useful Improvements in Door-Holders, of which the following is a specification.

This invention relates to door holders or fasteners and more particularly to devices of this character for use in holding open the doors of railway cars but which are applicable for use in other places.

The object of the invention is to provide a simply constructed and 'eiiicient device of this-character whereby a door will be securely yet yieldably held in open position and thereby prevented from accidental closing and yet be releasable on the exertion of a pulling force.

Briefly described, the fastener consists of a resilient socket memberto be mounted on the wall against which the door opens and a headed latch member carried by the door and positioned to enter the socket on the opening of the door and hold the door open, but which may be readily released by the mere act of pulling the door Shut.

With the foregoing and other objects in view, which will appear asv the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings Figure 1 represents a plan view of this improved fastener shown in applied position with a door held open,

Fig. 2 is a bottom plan view of the latch member,

Fig. 3 is an end view of the fastener shown in operative position,

Fig. 4% is a vertical section taken on the line 4.-4: of Fig. 1, and

Fig. 5 is a horizontal section taken on the line 55 of Fig. 1.

In the embodiment illustrated a socket member 1 is shown mounted on a wall W against which a door D is designed to open. This socket member comprises a base plate 2 having apertured ears 3 for the passage of the fastening bolts 1 which connect this member to the wall.

I Specification of Zhetters Patent.

Patented Apr. 16, 1918.

Application filed October 27, 1917. Serial No. 198,818.

Extending forwardly from the front face of the base plate 2 are a pair of spaced arms I 5 and 6, one of which has a projection 7 near its free end on its inner face as is shown clearly in Fig. 1 and which is designed for a purpose presently to be described. The other arm 5 has a threaded opening 8 therein,'-through which'passes a bolt 9 secured in adjusted position by a lock nut 10 and on which is mounted a coiled spring 11, a I

washer '12 being shown arranged between sald spring andthe inner face of arm 5. This coiled spr ng 11 1s also mounted on a pin 13 which projects from a tongue 1 1 carried by the base plate 2. This tongue 14: is here shown substantially L-shaped and the short arm 15 thereof is connected with the the remainder with its terminal'defiected as shown at 19. This deflected terminal 19 extends toward the arm 5 of the socket memher, a flared mouth being provided between. it and the inclined edge 7 of arm 6 so as to facilitate the insertion of the latch 20 carried by a casting 21 on the door D.

It will thus be seen that the spring 11 exerts its tension to force the tongue 14 toward arm 6 and the tension of this spring may be adjusted by adjusting the bolt 9 in a manner which is obvious. The tongue 14: will thus be yieldably supported and will permit the head 22 of the latch 20 to enter between it and arm 6 and to be yieldably held between them by the engagement of the projection 7 with a recess 23 formed at the inner end of the head 22 on one side thereof as is shown clearly in Fig. 1.

The latch carrying casting 21 is secured to the doorD by apertured ears 24: through which fastening bolts 25 are designed to pass. The latch 20 has its shank 26 disposed in a socket 27 formed in the inner face of the casting 21, said socket being larger than the shank to permit pivotal movement of the latch 20. A pintle 28 extends through the socket in the casting 21 and through the inner end of the shank of latch 20, and is held in operative position by a cotter pin 29 or other suitable fastening.

l/Vith the parts constructed as above described, the latch member being carried by the door and the socket member by the wall against which the door opens, and properly positioned to receive the latch 20, the opening of the door will cause the head of said latch to pass into a socket 30 formed between the tongue 14 and the inner face of arm 6, said latch member having a pointed nose 31 to facilitate its entrance between said parts. When the door reaches its extreme open position the head of the latch will have entered the socket 30 and the projection 7 on arm 6 will have engaged the recess 23 in said head, the yieldable tongue 14 under the action of its spring 11 releasably holding said latch in engagement with arm 6 thereby insuring the retention of the door against accidental closing. When it is desired to closethe door, all that is necessary is to exert a pull in the usual manner when the latch 20 will pass out of the socket 30 against the tension of spring 11 and the door may be closed in the usual manner.

From the foregoing description, taken in connection with the accompanying drawings the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains and while I have described the principle of operation of the invention together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown-is merely illustrative and that such changes may be made as are within the scope of the claimed invention.

I claim 1. In a door holder of the class described, a member having a latch extending laterally therefrom and provided with a projection, a catch member comprising a base plate having laterally spaced parallel arms one of which has a projection for interlocking engagement with the projection on said latch, a tongue carried by saidplate and positioned between said arms, a coiled spring disposed between the free end of said tongue and one of said arms whereby the tongue is yieldably forced toward the other arm for engagement with said latch to hold the latch in engagement with said arm.

2. In a door holder of the class described, a member having a latch extending laterally therefrom and provided with a projection, a catch member comprising a base plate having laterally spaced parallel fixed arms, one

of which has a projection for interlocking engagement with the projection on said latch, a tongue carried by said plate and positioned between said arms, a coiled spring disposed between the free end of said tongue and one of said arms whereby the tongue is yieldably forced toward the other arm for engagement with said latch to hold the latch in engagement with said arm, and means 7 for adjusting the'tension of said spring. 7

In testimony whereof I affix my signature in presence of two witnesses. v
