.iiPECIFICATION forming part of Letters Patent No. 701,135, dated May 2'7, 1902.

Application filed January 24,1902. Serial No. 91,070. (No model.)

To all whom it may concern:

Beitknown that I, GEORGE BICKELHAUPT, acitizen of the United States, and a resident of the city of New York, borough of Manhattan,in the county and State of New York,have invented a new and Improved Skylight- Opener, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved skylight-opener which is simple and durable in construction, easily manipulated, and arranged to allow of opening the skylight a desired distance for ventilating or other purposes and to automatically lock the skylight in place after the desired adjustment is made.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the im provement as applied, the skylight and curb being shown in section. Fig. 2 is an enlarged face view of the same. Fig. 3 is a sectional side elevation of the same. Fig. at is a side elevation of the improvement as applied and showing the skylight in a raised position. Fig. 5 is an enlarged sectional plan view of the same on the line 5 5 of Fig. 4, and Fig. 6

is a similar view of the same on the line 6 6 of Fig. 4. a A skylight A of usual construction is connected by hinges B to a curb C, and. on the.

free end of the skylight A is secured a bracket D, on which is fulorumed the upper end of a link E, pivotally connected at E with the lower end of a raising-bar F, mounted to slide vertically in a bearing G, secured to the in side of the curb O, as plainly illustrated in the drawings. On the upper endIof the raising-bar F is secured a guide II in the shape of aslotted bar, through which extends the link E, so that the latter is guidedin its swinging movement when opening or closing the skylight A. The raising-bar F is formed with spaced notches F, adapted to be engaged by a lever-catch I, fulcrumed at I on the hearing G, the lever-catch I being provided with a downwardly and inwardly extending arm 1*, pressed on by a spring I to normally hold the lever-catch I. in engagement with one of the notches F. In the arm I is journaled a pulley J, over which passes a pull-rope K, extending downwardly and passing under a pulley L, journaled on the lower end of the raising-bar F, the pull-rope then extending upwardly and passing over a pulley N, journaled on the bearing G. The rope then extends downward from the pulley N and is fastened to the lower end of the raising-bar F, preferably at the pivot E, as indicated in Fig. 6. The free end of the rope K extends loosely down the curb C to the floor below, so as to be within convenient reach of the operator.

The operation is as follows: WVhen the skylight A is closed, as illustrated in Figs. 1, 2, and 3, the lever-catch I engages the uppermost notch F in the raising-bar F to hold the skylight against opening. When it is desired to open the skylight, the operator pulls 011 the loose end of the pull-rope K, so that pressure is exerted on the pulleyJ and the arm I to impart a swinging motion to the levercatch I against the tension of its spring I to move the lever-catch out of the uppermost notch F. A further pull on the pull-rope K now causes the raising-bar F to slide upward in its bearing G, and in doing so the link E is carriedin a like direction, and thereby imparts an opening swinging motion to the skylight A. When the skylight is swung open to the desired position, the operator releases the pull on the pull-rope K, so that the levercatch I engages the corresponding notch F to lock the raising-bar in position and with it the link E and skylight A. From the foregoing it is evident that by the operator pull ing on the pull-rope K the lever-catch I re-' ceives an inward movement to unlock the raising-bar F, and then the latter is caused to slide upward until the skylight A reaches the desired position and is then looked in place on releasing the pull-rope, as above explained. It is understood that the arm I of the lever-catch I extends at an angle to the rope K, so that when the operator pulls the latter a swinging motion is given to the said arm I to swing the catch I out of engage ment with the corresponding notch F. The extreme upward sliding movement of the raising-bar F is limited by a stop-pin 0, adapted to abut against the lower end of the bearing G at the time the raising-bar has reached its uppermost position, and the skylight is completely opened.

When it is desired to close the skylight, the operator gives an initial pull to the rope K, so as to swing the lever-catch I out of engagement with the corresponding notch F, and then on slightly reducing the pull the weight of the skylight A causes a downward movement of the linkE and barF,while the catch I is held in an unlocked position until the skylight A is moved to a closed position on the curb C. It is understood that by having the link E connected with the lower end of the raisingbar F and with the free end of the skylight A the latter moves perfectly easy that is, swings up or down, according to the direction in which the raising-bar F is moved.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A skylight-opener, comprisinga link pivotally connected at its upper end with a hinged skylight,a fixed bearing, a raising-bar slidable in the said bearing and pivotally connected at its lower end with the said link, a locking device on the fixed bearing for locking the bar to the bearing, and manually-controlled means for actuating the said locking device and imparting a sliding motion to the said bar, as set forth.

2. A skylight-opener,comprising a link pivotally connected at its upper end with a hinged skylight, a fixed bearing, a raising-bar slidable in the said bearing and pivotally connected at its lower end with the lower end of the said link, a locking device for locking the bar to the bearing, and manually-controlled means for actuating the said locking device and imparting a sliding motion to the said bar; the said means comprising a pulley, a locking device, a pulley on the bearing, a pulley on the bar, and a pull-rope secured at one end to the raising-bar and extending over the said pulleys, as set forth.

I 3. A skylight-opener,comprising a link pivotally connected at its upper end with a hinged skylight, a fixed bearing, a raising-bar slidable in the said bearing and pivotally connected at its lower end with the lower end of the said link, a spring-pressed levercatch fulcrumed on the said fixed bearing and adapted to engage and lock the raising-bar in position, and means connected with the said catch and the said raising-bar to impart an initial movement to the said lever-catch to disengage the latter from the raising-bar, and to impart a sliding movement to the latter, as set forth.

4. A skylight-opener,comprising alink pivotally connected at one end with a hinged sky:

light, a fixed bearing, a raising-bar slidable in the said bearing and pivotally connected with the said link; a spring pressed levercatch fulcrumed on the said bearing and adapted to engage and lock the raising-bar in position, and means connected with the said catch and the said raising-bar to impart an. initial movement to the said lever-catch to disengage the latter from the raisin g-bar, and to impart a sliding movement to the latter; the said means comprising a pulley journaled on the bearing, a pulley journaled on the bar, a pulley journaled on the lever-catch, and a pull-rope fixed at one end to the said bar and passing over the said pulleys, as set forth.

5. Askylight-opener,comprisingalinkpivotally connected at one end with a hinged skylight, a fixed bearing, a raising-bar slidable in the said bearing and pivotally connected with the said link, a locking device for look ing the bar to the bearing,manually-controlled means for actuating the said locking device and imparting a sliding motion to the said bar, and a guide fixed on the said raising-bar for guiding the said link, as set forth.

6. A skylight-opener,comprising a link pivotally connected with a hinged skylight, a raising-bar having vertical guided movement and pivotally connected with the said link, a pivoted and spring pressed lever catch adapted to engage and lock the raising-bar, a pulley carried by the lever-catch, and a pullrope connected with the raising-bar and passing over the pulleyon the lever-catch, as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the prcsence of two subscribing witnesses.
