DOOR-OPENER.
Specification of Letters Patent.
Patented April 2o, 190e.
Application filed. October 15, 1908. Serial No. 457,899.
To all whom 'it may concern.'
Be it known that I, WILLIAM H. EDWARDS, a citizen of the United States, residing at Terre Haute, in the county of Vigo and State of Indiana, have invented certain new and useful Improvements in Door-Gpeners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in door openers.
The object of the invention is to provide an improved door opening mechanism adapted to be applied to any form of door whereby the latter may be automatically opened by the weight of a person approaching the same, and which will automatically close the same after the weight of a person has been removed.
With this and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be described and particularly pointed out in the appended claims,
In the accompanying` drawings, Figure 1 is a front view of a door showing the application of the operating mechanism thereto, parts of the iloor in front of the door and of the operating mechanism connected thereto being shown in section Fig, 2 is a horizontal sectional view through the door casing immediately above the door showing a top plan view of the operating mechanism; Fig. 3 is a vertical transverse sectional view throughA the floor and the hinged tread piece, showing the manner in which the latter engages and actuates the door-opening mechanismwhen the weight is applied thereto; Eig. L1 is a rear view of the door showing the arrangement of the closing mechanism; and Eig 5 is a detail perspective view of the door-opening lever Referring more particularly to the drawings, 1 denotes a door frame in which is hinged a swinging door, 2- In the licor or platform, 3, immediately in front of the door is formed a loose section or panel, 4, which is hinged at one end to the floor or platform joists, 5, or to any part of the supporting structure or framework of the platform in such manner that the end of the panel adj acent to the free end of the door may move up and down. The loose panel, 4, is provided with suitable cleats or other construction to prevent the same from warping, and the free end of said panel rests upon and is normally held in an elevated position by means of a combined supporting and operating lever, 6, one end of which is suitably hinged to the framework beneath the platform or licor, while the opposite end is connected to and supported by the lower end of a connecting rod, 7, the upper end of which has an adjustable connection with one end of a bell crank lever, 8, by means of an eye-bolt, 9, which passes through a slot in the end of one of the arms of the bell crank lever and has applied to its upper end an adjusting nut 10, in the lower side of which is formed a V-shaped notch, 12, which engages a V-shaped projection, 13, formed on the end of the bell crank lever, as shown. The engagement of the nut, 10, with the projection, 13, in the manner described, provides for a free rocking or pivotal movement between these parts,
The bell crank lever, 8, is pivoted in a supporting bracket, 1e, secured in suitable position on the side of the door frame near the upper end of the door, and in the upper arm of the lever is formed a series of holes, 15, by means of which the outer end of an operating rod, 16, is adjustably connected to said lever. The opposite end of the operating rod is preferably threaded and said threaded end is adapted to be screwed into a threaded socket, 17, the opposite end of which is preferably bifurcated, and is connected to one end of an operating lever, 18, which is pivotally mounted in a suitable bearing bracket, 19, secured to the door frame adjacent to and above the hinged end of the door. The lever 18 is provided midway between its ends with oppositely projecting hubs or bosses, through which, and through the lever, is formed a passage to receive the pivot pin of the lever, the ends of which are secured in the arms of the bracket, 19, whereby said lever is pivotally mounted in said bracket.
On the lower hub or boss of the lever 18 is formed a right-angularly projecting dooropening arm, 20, on the outer end of which is pivoted an anti-friction roller, 21, which is engaged with a channeled bar or track-way,
`22, secured to the upper end of the door, as
shown. On the outer end of the lever,18, is formed a clevis, 23, with which is adjustably connected one end of a door-closing spring, 24, the opposite end of which is connected to the door frame above the door whereby when the opening mechanism of the door is released said spring will automatically close
