To aZZ whom t mayconcern:V i' v A 'Be 1t known that l, ABRAHAM ,KELLER, a

citizen ofthe United States,'residing at San Francisco, in thecounty of- San Francisco and Stateoi" California,-have invented new and useful Improvements =in Safety Devices for fDoors, ofV which the 'following is a specification.l l l v This invention relates door attachmentsand has particular refer* ence to a safety device adapted to be applied 'to various typesof doors, particularly to the doors of railway passenger coaches.

The primary object' of this invention is tov provide afsafety device of the character described which can be readily attached to a door in order to prevent the slamming of the door, which not onlyfshortens the life of vthe door and the frame structure-"but often `s-.extremity a causes injury to tothe door. y Y A., ,Y

Another object of this inventionistoproi' vide a safety device adapted vto'operate uponV a person -in close proximity movement of the door knob and whichic'an 'of thefollowing description T Y be readily'applied to' various typesl of ldoors Without materiallyl altering `the L construc- VVtion thereof;y f'

L- furtherY object to this invention tis i.to

provide' a device fof the above mentioned character which 1s simple 1n construction7 inexpensive to manufacture, easily assembled Vand' disassembled, strong, durable and'highly efficient. n e v Other objects and 'advantages oit'V the invention ,Will be apparent during the course Great annoyance hasbeen lexperienced by the repeated slamming of doors, particu- *larly those of railway passengervcoaches,

with a consequent disastrous effect not only to the door and door frame, but` oftentimes lto travellersy who have been caught in the slamming-doors. To overcome these ob-Y jections, I have devised the present safety attachment,`which will prevent a door to which it is applied from slamming, andV thereby supply a longneeded want. n

In the'accompanying drawings forming a vpart of this specification and in which like numerals are employed toV designate like parts throughout the same,

Figure 1 is a side elevation of my improved attachment'partly in section, as applied to a door, the view being taken on the line 1--1 of Figure 2,
