## Abstract

A door latch operator for retracting a door latch comprises a handle having upper and lower end portions formed with front faces attachable to a door and a vertical hand grip portion between the upper and lower end portions. The upper end portion is in the form of a hollow housing having a chamber therein. The hand grip portion is in the form of a generally U-shaped channel which communicates at one end with the interior of the housing. A lever for operating the door latch is pivoted in the housing and extends into the channel in the hand grip portion to a position where it may be squeezed and rotated from a withdrawn position to a latch retracting position by a hand on the hand grip portion. The handle and the lever are both solid brass forgings.

## Claims

### Claim 1

Door latch operating mechanism for retracting a door latch, comprising:
a solid brass handle having upper and lower end portions formed with front faces attachable to the surface of a door and having a vertical hand grip portion between the upper and lower end portions spaced rearwardly from said front faces and away from the surface of the door,
said upper end portion being in the form of a hollow housing having a chamber therein,
said hand grip portion being generally U-shaped in cross-section defining an elongated vertical channel which opens forwardly and communicates at one end with said chamber,
a solid brass lever adapted to operate said door latch,
said lever being pivoted in said housing on a pivot pin extending across said chamber whereby said lever extends downwardly from said pivot pin into said channel in said hand grip portion to a position where it may be squeezed and rotated from a withdrawn position to a latch retracting position by a hand on the hand grip portion,
means for securing said housing to the door including a mounting block affixed within said chamber,
means for securing the lower end portion of said handle to the door,
said housing having a bottom wall and said chamber having an opening through said bottom wall which extends in continuation of said channel, and said lever has an integral flange closing said opening in the withdrawn position thereof, and
said mounting block being completely concealed in said housing when said handle is secured to the surface of the door and the lever is in the withdrawn position.
