Be it known that I, KIMBELL a citizenlof the United States residing at Rice L 8.k6, in the county oflBarro'n and State at Wisconsin, have invented certain new an usefulv Improvements in Door The present invention relates tothat'class of devices known as door openers, and more esper'iiallyv to those which-are adapted to be operated by the foot.- I
' An object of this invention isthe provision of door opening means which may be readily applied to or detached from a doorlatch.
further object is the adapting of the opener to; doors of various thicknesses while enabling manipulation of the opener on both sides of the door. v i v The invention has for a still further object the. revision of a, door opener of'this class in w iich a spring is utilized for the purpose -'of operating the same in lieu of the cumbersome weights. now employed in devices of this cl. aracter.
Other objects and advantages will be apparent from the following description, and it illustratedns applied to an ordinarydoor,
Fig. 2 is a transverse, vertical section through. the latch spindle sleeve detached,
\ connected parts being seen in elevation,
Fig. 3 is a top plan View of the foot levers.
Referring to the drawings, 10 represents a door of any ordinary construction which is hung in the common frame 1 1.. An ordinary latch lock 12 is attached in the usual manner to the door 10, the ordinary spindle 13 extending outwardly from the latch and being provided on its ends with knobs 14.
Upon the spindle 13, a sleeve 15 is secured preferably by means of a set screw 17 in such a position that the rojectlon or crank arm 16 extending thererom will extend at the roper angle with respect to the mechanism ii I end to one of said foot levers of asleeve;
creinaftcr described. The arm 16 is of "which the following is' a speci-' Specification of Letters Patent.

in which is secured a depending connecting cured to a foot lever 20 through an eye 21. Obviously the connections of rod 19 are sufficiently loose for permitting the necessary movement of the rod during operati n. The lower portion of the door is apertured, as at serve as bearing fora spindle or shaft 24 extending through the aperture 22. The lever nected to a lever 25, similar in construction and arrangement to lever 20, the levers 20 and 25' being thus arranged on opposite sides of the door, and each being provided with a treadle of any suitable type extending laterally from the door in position for being engaged by the foot of the operator. i
In order to. enable adjustment of the the door, the lever 25 is bored transversely said spindle is slidingly extended through tion by a set screw 26 threaded through the end of the lever 25 into engagement with the spindle. The end of the lever 25 which at 27, for forming a stop adapted to contact with the respective escuteheon 23 for evers are applied to a door. spring 32 is connected, as at33, to the sleeve 15 while its opposite end is secured to, the connecting rod 19 for the purpose ofraising freed after operation.
readily be applied to any ordinary door.
The operation of the device is as follows When it is desired to open the door, one of the foot levers is depressed by the foot of the the arm 16 and whereby the s indle 1 3' is lateral movementof the foot on the foot lever will cause the door to open.
What is claimed is combination with a pair of spaced foot levers and a connecting rod secured at the lower formed, at its free extremity, with aneye 18 i adjustably positioned. upon the spindle oii a for the reception of the spindle 24, and the.
