CARL JOHN HAGSTROM, OF GLEN COVE, YORK.

TRANSOM ADJUSTER.

.Application filed July, 9, 1925. Serial No. 42,348.

This invention relates to building construction and has particular reference to de vices for operating transoms or similar structures. j i

Among the Ob ectsoftlns lnventlon is to provide mechanism to facilltate the operation of a transom or the like and whereby,

said transom may be readily locked shut or opened to any desired extent by the operator from some point of vantage.

Another object of this invention is to pro vide generally a novel power transmission device, and particularly one which is applicable for use in connection with tran soms or other movable objects, and whereby the operation of said transom may be 'ac- (jOll'lPllSllBCl from a point removed therefrom according to the convenience of the operator.

Still another object of this invention is to provide in conjunction with a movable object such as a transom or the like mechanism comprising a lock which is arranged for retaining said transom in a fixed or locked position and means co.-operating with said lock in a novel manner and whereby said transom may be opened or closed as desired. 1

lVith the foregoing and other objects in View the invention consists in the arrange ment and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed or suggested herein, still for the purpose of illustrating a prac tical embodiment thereof reference is had to the accompanying drawings in which like reference characters designate the same parts in the several views, and in which Figure 1 is a perspective view showing a typical use of my invention in connection with a transom which is in open position.

Fig. 2 is a front elevation of the same but with the transom in closed position.

Fig. 3 is a section on the line 33 of Fig. 2.

Fig. 4: is a section on the line 4.--4 of Fig. 3.

Fig. 5 is a section on the line 5-5 of Fig. 8.

Referring now more particularly to the drawings, I show my invention as used in connection with a movable or pivoted structure such as a door or transom comprising a sash 10 arranged to be received in a frame 11 above a door 12. Means is provided for retaining said transom in adjusted or locked position such as a lock 13. Preferably said lock is secured to said sash, and has suitable co-operation with a member such as a strike 14: which is mounted upon the frame 11. The sash is mounted for opening and closing as desired and is preferably hinged to said frame by means of the hinges 15. The lock mechanism may therefore be arranged to have engagement with its strike when said sash istilted from one position to another as when the transom is closed. For this purpose the lock is provided with a movable bolt 16 which is actuated by a spring 17 so as to engage the strike automatically. The bolt may be pivoted upon a pin 18, upon which likewise the spring may be secured as by means of a coil 19 formed upon the pin and whereby the free portion of the spring abuts against the lock casing and thus exerts a force upon the bolt tend- .ing to throw the same toward the left, the strike being formed in the shape of a hook or catch to readily engage the same.

Means are provided whereby the transom may be operated from any point most convenient to the operator, said means comprising one or more flexible members such as the ropes 20 and 21 whereof the former is arranged for use in closing the transom while the latter is used for opening the same. As stated hereinbefore, I contemplate generally means whereby the transom may be fixed for any desired adjustment or tilted position as to vary the flow of air therethrough or for any other purpose as desired. and for the sake of simplicity, I have found it most convenient to secure this object by providing means such as a locking device 01 friction brace 22 which is operable in con junction with the flexible members aforesaid. Said friction brace is a Well known telescopic device which is pivotally mounted for easy and eflicient co-operation with the transom.

The rope 20 has co-operation with a stationary object such as the frame 11 as by means of an anti-friction member such as the pulley 23 whereby the direction of power transmission by means of the rope may be changed in a convenient manner. More specifically, the rope 20 after passing vertically upward and then horizontally over said pulley to a point adjacent to the strike has engagement with another antifri-ction device and then with the sash in such manner that a downward force apwiththe pulley 23 the rope may extend sub stan-tial'l-yparallel thereto in a neat and efficient manner. The rope then passes rearwardly behind the pulley 26 and then forwardly into engagement with the sash, the

pulley 26 being arranged to. take up the forceexerted along the rope in closing the transom. Thus said rope may be secured to a member such as a lug 27 formed upon the lock casing and generally to any relativelystationary member or part whereby the sash may be moved. The rope is passed through a hole in the lug and is then formed with a knot 28, the lug being offset inwardly toward the frame. 11 to provide clearance between the bolt 16 and: said knot.

Means is provided for opening the tran som in conjunction with the rope 21, and for disengaging the bolt from its strike should the transom be locked. Thus the rope. 21 may be secured to. the bolt as within the hole 29 thereof, a knot 30: being provid'cd to retain.- the same in engagement, the rope entering the look through. the side of the casing. As a neat and preferred arrangement, I provide a pivoted member suchas a bell crank 31 m oanted uponthe sash with one arm of which the vertical portion of the flexible member 21 has engagement while with the, other arm of which a horizontal portion of said member has co-operation for transmitting a force exerted at the knob 32 for tilting the bolt in clockwise direction to open the'lock. By continuing the pull upon said knob, thetransom will be opened against the resistance of the frie tie-n brace 22 and final-lyleft in any open.

extending along. said construction whereby' the sash may be operated from a distance, said flexible means comprising a. plurality of flexible members one ofwhich extends: along the frame and substantially parallel to the surface thereof, and a pair ofpulleys. recessed in said frame, one of which takes, the direct pull tending to actuate the sash toward said frame, thev other pulley being positioned forwardly of the. first mentioned pulley and acting as a guide for said flexible member from the other pulley and to bring the member to the surface of the frame.

In testimony whereof I my signature.

CARL .lOHN HAGSTROM.
