UNITED STATES Parana CHARLES E. \VHITNEY, OF BROOKLYN, NEXV YORK.
DOOR-OPENER.
SPECIFICATION forming part of Letters Patent No. 325,299, dated September 1, 1885.
Application filed December 17, 1884.
To aZZ whom it may concern.-
Be it known that I, CHARLES E. IVHITNEY, of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Door-Openers, of which the following is a full, clear, and exact description.
Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures. V
Figure 1 is a front elevation of one of my improved door-openers. Fig. 2 is a rear elevation of the same, the back plate of the case being removed. Fig. 3 is a sectional plan view of the same, taken through the line w m, Fig. 1. Fig. a is arear elevation of the gearwheel.
The object of this invention is to provide door-openers so constructed that the striker cannot be forced back from the outside, and which shall be more easily operated than ordinary door-openers.
The invention relates to a doonopener constructed with a slot in the striker to receive a pin upon the gear wheel, which is operated by a rack'bar and spring, whereby the said striker will be locked in place by the said pin, and can only be moved by the movement of the said pin, as will be hereinafter fully de scribed and claimed.
A is the front plate of the case, which is made with a recess, B, to receive the rack-bar G, recess, D, to receive the gear-wheel E, and a slot, F, in its forward middle part to allow the striker G to move back.
In the plate A, at the upper end of the rccess B, is formed an opening, through which the upper end of the rack-bar 0 projects, so that the wire H, leading to the upper stories of the house, can be readily attached to it.
The striker G slides on guides I, formed upon the front plate, A, and is kept in place by the back plate, J, secured to the said front plate by screws.
The rack-bar O is drawn down, after being drawn up, by drawing upon the wire H by a spiral spring, K, the lower end of which is attached to a stud, L, formed upon the front plate, A, at the lower end of the recess B, and its upper end is attached to astud, M, formed upon the rack-bar (3.
The geanwheel E revolves upon a stud, N, formed upon the plate A.
(No model.)
I do not claim the above construction as of 5 5 my invention, but will now proceed to describe and then claim my improvements thereon.
Upon the gear-wheel E is formed a pin, 0, which projects through a slot, P, in the striker G, so that the striker will be drawn 6c back by turning the said gear-wheel.
With this construction, when the wire H is drawn upon, the rackbarO is drawn upward and turns the gear-wheel E, causing the pin 0 to move upward and rearward through the slot P. As the pin 0 comes in contact with the striker G, at the rear side of the upper part of the slot P, it draws the said striker G back and allows the door to swing open.
The slot- P is enlarged at the rear side of its lower part, so that the pin 0 can still have a forward movement should the tautness of the wire H be such that the striker G will be drawn back fully before the rack-barG has completed its movement. his arrangement makes provision for the stretching of the wire H, and insures the drawing back of the striker to the proper point,even when the stretching of the said wire H prevents the rack-bar G from being drawn upward to the limit of its movement.
When the wire H is released, the rack-bar C, gear-wheel E, and striker G are drawn back to their 11 -rmal position by the tension of the spring K.
With this construction, should an attempt from outside the door he made to force the striker G back, the said striker, at the forward side of the slot P, will strike against the pin 0, and will thus be held from moving 0 back, so that the said striker can be drawn back only by the upward movement of the rack-bar 0.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
In a door-opener, the combination, with the striker G, having slot P, of the gear-wheel E, having pin 0, the rack bar C, and the spring K, substantially as herein shown and de- IO scribed, whereby the said striker will be locked in place by the said pin, and can only be moved by the movement of the said pin, as set forth.
