end thereof engage the upper edge of the gate for holding the same lowered ordepressed when moved position manu- To all whom it may concern:

Be it known that I, JOHN M. GAMBLE, a citizen of the United States, residing at Burlington, in the county of Des Moines and State of Iowa, have invented certain new ally against the action of its retractile `spring.` A spring is provided for normally holding said catch in engagement with the gate for maintaining the gate in a depressed position. When it is desired to open the gate all that is necessary is to press upon the upper end of the catch which will cause t e lower end thereof to move from above the gate. This will permit the retractile spring to immediately elevate the gate, and thus present an opening through which articles may be passed.

In order that the invention may be more clearly `understood an embodiment of the same is shown in the accompanying drawings, in which 1 indicates a ticket window having the usual openin formed therein. In the opening in the tic positioned plates 2 and 3. The plates 2 and 3 are held 1n roximity by suitable bolts 4, but are also he d spaced apart by washers 5, preferably of some elastic or yielding material, as rubber. When placing the plates 2 and 3 in position, plate 3 is placed upon the outsideof the wlndow, and the are drawn toward each other until the same engage the window l, the yielding washers `5 permitting such movement. Each of the plates is formed with a cutout portion 6 which registers when the plates are in osition for forming a restricted opening through which articles, as for instance money, may be passed. Secured to plate 2 are slides 7 and 8 which guide gate 9 in its reciprocatory movement. Gate 9 is formed with a main body portion 10 designed to close the opening formed by cut away portions 6-6, and a thumb member l1 which is designed to be pressed manually for lowering the gate. The upper end of the gate is formed with a turned over portion 12 which is engaged by a retractile spring 13. Retractile spring 13 is secured at 14 to plate 2 and is designed to be stretched when gate 9 is in its lowered position, as shown in Fig. 2, so as to move the gate upward yto the position shown in Fig. 1, and maintain the same in that position when the gate has been Ticket-Window Closures; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertainsto make and use the same.

v'This invention relates to improvements in means adapted to fitinto a ticket window for normally closin the same. y

Another object o? the invention is the arclosing a ticket window but adapted to automatically open on being released.

A further object of the invention is the ar:-

automatically opened when release With these and other objects in view the invention comprises certain novel constructions, combina-tions and arrangement of *In the accompanying drawings: Figure 1 the inventionshown 1n position. Fig. 2 is a section through Fig. 1, approximatel on line 2-2. Fig. 3 is a front view o the structure shown in Fig. 1 with the front plate removed, the same being shown on a reduced scale. Fig. 4L is an enlarged fragand pivotal securing means therefor.

In constructing the window ticket slide or closure embodying the invention a pair of plates are connected but spaced apart by suitable washers sufficiently for accommodating the thickness of the window to which the closure is to be applied, so that the edge overlap the opening in the hold On one of the plates slides between which .gate having the edges es, normally held elethe closure in place.

When it is desired to open gate 9 the upper end of latch 17 is pressed inward toward plate 2, as shown in dotted lines in'Fig. 2. This will cause the move from above extension 12, and permit retractile spring 13 to elevate the gate. The latch 17 is provided with a substantially arc-'shaped portion 20, through 21 is passed formed with a substantially arc-shaped head 22 for comparatively loosely holding the latch in position, so as to permit a free pivotal movement thereof.

Vhat I claimis: 1. In a device of a closure formed with an a sliding gate for closing silient means for normally holding said gate open, and pivotally mounted means for holding said gate closed .against the action of .said resilient means. l

2. In a device of the character described,

a closure proper formed with an opening therein, a sliding `gate therefor, a spring the gate when said catch has been released.

6. In a device of the character described, a closure proper formed with an opening, a reciprocatory gate for said opening, al pair of Guide ways proper or guiding said gate in its movement, a retractile spring secured at one lend to said closure proper and at the other end to said gate for normally holding said gate' open, and a spring pressed with a hook-shaped end for engaging the upper edge of said gate for holding the same closed after having been manually moved to a closed position.

the character described, opening therein, said opening, re-

formed with registering for holding said plates in means for preventing the i an open position, and a catch for holding said gate closed when moved to a Vclosed position.

3. In a device of the character described, a closure proper Jformed with an opening therein, a slidinggate for normally closing for holding said gate in its closed position, and a retractile spring said gate when said last mentioned means has been released.

V41. In a device of the character described, a closure proper Jformed with an opening, a gate for said opening, a retractile spring for tending at all times tofhold said gate said plates and said securthe disa witnesses.
