JOHN u GAMBLE, or nunLrnof'ron,Iowau WINDOW.

AppIication led November4 21, 19227.` `Serial No. 234,751.

Thisinvention relates to ticket windows, and aims to provide novel means whereby a ticket window may be closed and locked against the same being opened from the outside and at the same time al'l'ords means to keep out the cold during winter.

An important object of the invention to provide a device of this character which may be readily moved to its active or closed m position and one which may automatically move to its inactiveor open position when the lock is operated to release the closure.

A still further object of the invention is to provide a closure of this character which may be readily and easily secured to the winow without danger of breaking the rwin-` Vith the yforegoing and other objects in View which will appear as theV description s proceeds, the invention resides in the `combination and arrangement of parts and in the details of construction hereinafter described Y and claimed, it being understood 'that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without de parting from the spirit of the invention.

Referring to the drawing:

Figure 1 is an elevational view illustrating a ticket window constructed in accordance with the invention.

Figure 2 is a sectional view taken on line 2-2 of Figure 1. y

Figure 3 is a transverse sectional view through the closure.

Figure 4 is a fragmental bottom plan view of the closure, and frame in which it is mounted.

Referring to the drawing in detail, thede- 'i vice includes a pair of plates and 6 respectively, the plate 5 constituting the outer plate while the plate 6 constitutes the inner plate.

These plates are provided with inturned edges 7 that are designed to closely engage the glass of which the ticket window is con structed.

Bolts indicated at 8 extend through openings in the outer and inner plates, the bolts being provided with nuts 9 whereby the plates may be secured together, provided rubber spacing members 10 for olding the plates in proper spaced relation with each other and at the same time, providing guards for the bolts against which the glass may rest.

The spacing member 10 is disposed adthere being jacent to theupper edge of the frame is elongatedas shown by Figure 2l and acts as a stop for the sliding closure l2whenthe closure is moved to the limit of lits upward movement by the action of the spring 13.

Formed on the inner pla-tc of the closure I frame, are guide membersl 111 in which the closure Y12 slides, the guide members being formed of channel material and secured ad jacent to the opening in the frame through which the tickets are passed.

` Formed integral Awith the closure 12 is a hook member 15 under which the spring 13 engages, of positioned in the tubular support 16 and provided with a coiled portion 17 for lending resiliency to the spring. Thus it will be seen that under normal conditions, the action of the spring 13 is' to hold the closure in its inactive or open position.

The hook member 15 is slightly offset dening a shoulder 18 which is engaged by the pivoted latch member 19 supported on the inner surface of the inner plate, the latch member being spring pressed so that the lower end thereof is normally held against the closure 12 with the result that when the closure is'moved downwardly to theV limit of its closed position, the latch member will find its way into engagement with the shoulder to hold the closure in its closed position. f

Should it be desired to move the closure to its open position, it is only necessaryV to push the upper end of the latch 19 inwardly causing the lower end of the latch member to disengage spring 13 to act to move the closure toa position as shown by Figure 3.

Formed integral with the closure 1Q and the spring 13 having one end therethe shoulder and allowing the extending inwardly therefrom is a flange 2O p to be engaged by the fingers of the person selling the tickets and forced downwardly to move the closure to its closed position after a sale has been made.

It will thus be seen that when'the closure Vis moved to its closed position, the latch member will lock the closure in such closed position, to the end that it may only be opened by releasing the latch .at the rear of the frame.

I claim:

1. In a device of the class described, a pair of plates having registering openings, a sliding closure operating between the plates, said closures having a hook formed tween the plates, a closure mounted for slid? ving movement in the guideways, an elongated spring having one of its ends anchored laterally of the closure, the opposite end ot the spring contacting with the closure to normally urge the closure to its open position, a latch member 'for locking the closure in its closed position, and a iange on the closure to be engaged by the hand of the operator to `move the closure to its closed posit-ion.

3. In a device of the character described, a pair Vof plates; means for securing the plates in spaced relation With'eachother, a slidino closure operating between the plates,

v said closure having a hook, a spring having one end thereof disposed under the hook, the opposite end of the spring being anchored to one of the plates, said spring adapted to normally urge the closure to its open posi.- tion, and a latch member pivotally supported at one of the plates and adapted to engage the closure to lock the closure in its closed position.

In testimony that I claim the foregoing as my own, l have hereto aiixed my signature.
