, Specification of Letters Patent.
Patented Sept. 29, 1908.
' "Applicationfiled bctober15,1906. Serial No. 338,900.
To all whom it may concern- Be'it known that 1, JOHN E. Osnnma citizen of the United'S'tates, residing at Chicago,
in the county of Cook and State of Illinois, have invented certain new and useful Im-I provements in Door-Operating Mechanisms, of which the following is a specification This invention relates to means for opening and closing a door, and is herein shown in connection with a swinging door, though ap plicable as well to sliding doors.
The embodiment herein shown of this inventionis particularly intended for opening and closing the doors of railway cars, and the object of the invention is the provision of means, in a door-operatingfmeehanism, for cushioning the closing movement of the door in order to prevent injury to the hand. or other part of the person of a passengerthat maybe in the doorway when the door is bein closed. v I n the accompanying drawings, Figure I is a top plan view of a door-operating mechanism embodying the features of my invention,-
said mechanism being illustrated in. operative relation to a swinging door. .Fig. 2 is a fragmental detail View, partly in section, of a link comprised in said door-operating IHGGh-g' amsm. A refers to a doorway andIB' to a swinging door for closing said doorway.
The door-operatin mechanism comprises a motor 1, which, int 's instance, is substantiallysimilar to the compressed-air-motor shown and described" in my oo-pendingap plication No. 328,254, filed July 28, 1906.-
The motor 1 comprises an 'oscillatoryoperatf ing lever 2, and a valve mechanism 3 for oontrolling the mo ements of said lever. ,The motor 1 is adapted to be supported upon a. side wall of the car, or in any otherconven ient location with the lever 2 arranged to swing in'a'horizontal plane. The outer end of the lever 2 is connected with the door B'- by means of a link 4. To permit the door to be yieldinglystopped so as to prevent injury to a passen er who may have his hand in the doorway w on the door is being closed, the liiik 4 is made in two telescoping sections 5 and 6. The section 5 is bifurcated at one'end for attachment to the lever 2, the opposite end of said link-scc- I tion being reduced in diameter, providing an annular'shou-lder 7, between which shoulder and a pin 8 fixed in the tubular section 6 of the link 'is' interposed a coiled spring 9. To
limit the movement of the links'ections 5 and 6 with relation to each other a pin 10 is' ableposition to limit the door-closing move-- ment of the lever 2, said lever and the link '4 being in alinement when the door is fully closed. a l
' In use, the motor 1. is operated to swing the lever 2 to open and close the door as deportioned that when the door is fully closed said lever and said link are in alinement,
time looking said doorin its closed position. ,It-will beseen that the end of the closing movement of: the door B is cushioned by thespring 9 to preventinjury, should a passengers hand he caught in the doorway when sa d door is being closed.
I claim' as my invention:
' 1 1. In a door-operating mechanism, in combination, a motor, a lever actuated by said motor, a link for connecting said lo er withv the'door, and acushioning device in said link.
2. In. a (l001--0p(:IZil.-l]lgillfbOllftlllSHh lll combination, a n'njitor; a lever acitcd to i: moved by said lnotor; and a link tor eon meet ing said lever with the door; said l ever compris'ing two telescoping sections, a spring interposedbetween said sect-imis, one of said link-sections having a slot therein, and a pin. fixed to said other.liiilosoction and extending within said slot.
