PAUL C. BRENNER, OF CHICAGO, ILLINOIS.
DOOR-OPERATING DEVICE.
, TbraZZ fwlm-m it ma concern cago, .in the'county of Cook and State of Illinois, have invented new and useful Improvements. 1n, Door-Operatmg Devices, of
which the following is a specification.
Thiswinvention relates to door operating devices and especially to means for operating, swinging doors.
'Theinvention has for its object to produce a-swinging door of simple and improved construction which will be actuated by a personstepping on a foot board or operating board to swing open and to remain in an open position until the person steps oii' the operating board, it being understood that two operating boards are provided, one at each side of the doorway.
A further object of the invention is to simplify and improve the operating or actuating mechanism of the door and to provide a construction which is simple, durable and inexpensive.
Withsthese and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.
In the accompanying drawings has been illustrated a simple and prefer-red form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural. details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.
In the drawings, Figure 1 is a view in sectional elevation showing a doorway and a door, the latter being partly open. Fig. 2 is a vertical sectional view taken on the line 22 in Fig. 1. Fig. 3 is a horizontal sectionalview taken on the line 33 in Fig. 1. Fig. 4: is a horizontal sectional view takcn on the line 4;1 in Fig. 1. Fig. 5 is a sectional detail view taken on the line 5-5 in Fig. 4. Fig. 6 is a perspective detail view of the operating lever and related parts, including parts of the operating boards, the latter having been partly broken away.
Corresponding parts in the several figures are denoted by like characters of reference.
The operating mechanism of the improved door is partly incased beneath the floor 10 Specification of Letters Patent.
Patented Mar. 3, 1914.
Application filed June 25, 1913. Serial No. 775,735.
I so as to be out of sight and in a position where it will ,present no obstruction. Said mechanism includes a lever 11 of a length approximately equal to the width of the doorway, said lever being fulcrumed on an upright or supporting member 12 directly beneath the place where the door sill would ordinarily be located. H
The short arm of the lever is bifurcated at 13, and it carries a pivotally supported member 14 having in its upper portion a circular recess constituting a ball race 15 wherein ant-i -.iriction balls 16 are placed to support a cylinder 17 having spirally disposed grooves 18. The cylinder 17 is carried at the lower end of a pintle 19 extending downwardly at one side edge of the door 20, a corresponding pintle 21 being arranged to operate in a bearing 22 at the upper end of the door frame 23. A bracket 24: which is secured on one of the posts of the door frame carries a bearing sleeve 26 wherein the cylinder 17 is fitted for vertical and for oscillatory movement, said sleeve being provided with inwardly extending studs 27 that engage the spiral grooves 18 in the cylinder.
The long arm of the lever 11 has an upwardly bulging portion or hump 28 carrying an anti-friction roller 29 which contacts with the barrel of a hinge 30 which serves to connect together the foot boards or operating boards 31 that extend from opposite sides of the doorway, the free ends of said operating boards being loosely and slidably supported on the flooring 10. The parts are so proportioned and assembled that the hinge member whereby the operating boards the posts of the door frame so as to prevent lateral displacement of the lever arm.
From the foregoing description, taken in connection with the drawings hereto an nexed, it will be readily seen that a construction is provided whereby the weight of a per-' son stepping on one of the foot boards will depress the long arm of the lever, elevating the short arm which carries the member 14 on which the cylinder 17 is supported fororted so as tomaintain; an approximately orizontal position while the lever is being tilted. The cylinder 17 being forced upwardly through the bearing sleeve 26 will be partly rotated by the action of the inter.- engaging spiral grooves 18 and lugs 27, thus causing obvious" that the pintle 21 and its bearing 22 at the top of the door frame must be.
constructed and proportioned to permit the necessary lifting of the door. As long as theweight of the person is imposed on either operatingizboard, the door will remain in an open position, but as soon as the person "steps ofi the operating board, the door will gravitate downwardly and swing shut.
'IjIaying thus described the invention, what is claimed as new, is
1. A swinging door supported for verticalmovement by means including a bearing sleeve having inwardly extending lugs, a
spirally grooved cylinder carried by the door and operating in the bearing sleeve, a lever having a bifurcated arm and a member on which the cylinder is su ported for rotation about its axis, said mem er being pivoted on the} bifurcated armof the lever.
2. A swinging door supported for vertical movement by means including a bearing the door, while being slightly ele-. vated, to swing to an open position. It is sleeve having inwardly extending lugs, a
spirally grooved cylinder carried by the door and voperating in the sleeve, a lever, a member pivotally connected with an arm of said lever and having a circular recess receiving the lower end of-the cylinder, and anti-friction' members in said recess.
' 3. A swinging door supported for vertical movement by means including a bearing sleeve and a'spirally grooved cylinder car-.
ried by the door and operating in said sleeve,
a lever, one arm of which supports the cylinder and the other arm of which has an eye, and a keeper on which said eye is guided.
4:- A swinging door supported for vertical movement by means including a bearing PAUL C. BRENNER.
