TELLEFIS WINDOW.

Specication of Letters Patent.

Patented April 2, 1907.

Application filed March 21, 1906. Serial No. 307,178.

To @ZZ whom, t may concern,.-

Be it known that I, EMERY LIBERTY, a citizen of the United States, residing in the borough of Manhattan, city of New York, county and State of New York, have invented certain new and useful Improvements in Tellers Windows, of which the following is a specification.

This invention relates to improvements in tellers windows of the type shown in my Patent No. 774,190, dated November 8, 1904, which is characterized by a window which may be elevated above the counter, so that a larger opening will be produced when desired.

The objects of the present invention are to simplify the construction of the mechanism, render it more certain and silent in operation, and other objects, which will more fully appear from the following specification and claims.

I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a perspective view of a window, counter, and operating mechanism for the wicket. Fig. 2 is a top view of the operating mechanism, and Fig. 3 ya slide elevation thereof. Fig. 4 is a detail of the portion of the mechanism shown in Fig. 3, showing the parts in the position they will assume with the wicket raised.

ln all the views like parts are designated by the same reference characters. v

In carrying out my invention I'provide the wicket or window 1, which is arranged above the counter 2, as disclosed in my patent before referred to. The wicket 1 has depending side portions 3, which pass through openn ings in the counter and slide within the guides or ways 4 in the sides of the window. Provision is made to permit the wicket to be raised to the position shown by the dotted lines in Fig. 1. This raising mechanism is as follows: The two depending portions 8 are connected together by the horizontal crosspiece 5. To this cross-piece is secured a vertical lifting-rod 6. The upper end of the latter may be forked, as shown, and secured to the cross-piece 5 by means of a pin, so that an exact nicety of alinement between the rod 6 and depending portions 3 is not necessary to be attained in order to get a smooth operation. The rod 6 extends down below the counter and passes through a guide or bracket, which is shown as an angular plate with a hole through it, through which the rod 6 passes. This guide or bracket 7 is secured to a backing 8, which may be a plate of sheet metal, a board, or other device, secured to a portion of the support of the counter. The elevating mechanism and lock are secured to and carried by the backing 8.

The elevating mechanism comprises a chain 9, which is secured to the rod 6 by means of a clip 10. This chain 9 passes over a sprocket-wheel 11, which is mounted upon 'a shaft 12, which turns in bearings carried by the backing 8, and a frame 13, formed of an upright piece and a horizontal piece connected together, as shown. The other end of the chain 9 is connected to a counterweight 14. This counterweight is in the form of a box, having a bail to which the chain is attached and provided with the clips 15, which engage with a guide-rail. The guiderail 16 is vertically arranged in a proper position so that the weight 14 will slide up and down upon it. The guide-rail is T-shaped in crosssection (see Fig. 2) and is secured by bolts or rivets to the backing 8, the shape of the rail permitting the clips 15 to engage with the edges of the rail and to guide the counterweight, preventing it from coming out of contact with the rail. The box constituting the counterweight may be made with walls sufficiently thick to constitute a sufficient weight, or if additional weight is required it can be made by introducing shot or other weights into the box 14.

The sprocket 11 is rotated by means of a pinion 17, free to turn upon the shaft 12 (see Fig. 2) and provided with a finger 18. This finger is adapted to engage with the nger 18, carried by the sprocket 11, when the pinion 17 is rotated, and thereby constitutes aV lost-motion connection between the pinion and sprocket. The pinion 17 is rotated by means of a rack 19, which is connected to and carried by a rod 20. The rod 20 passes through a hole in the bracket 7, and its lower extremity is connected to a pedal 21. As shown in Fig. 1, the pedal 21 is fulcrumed upon a support 22, which rests upon the iioor, and its inner end is connected to the lower end of the rod 2O by means of a link 23, a second link 24, formed of a plate engaging between notches in the extremities of the link 23 and rod 20, connecting the two latter together. The rod 20, rack 19, and lever 21 are so arranged that upon the teller depress- IOO ing the outer end of the pedal with his foot the rod and rack 19 will be elevated, rotating the pinion 17 and causing the finger 1S to engage with the finger 18a, which in turn will rotate the sprocket 11, lift the rod 6, and with it the wicket 1. The sprocket 11 is preferably made sulliciently large so that the wicket may be completely elevated through not more than one revolution of the sprocket.

The rack 19 is held in engagement with the pinion 17 by means of a roller 25, which is carried upon a support 26, which is secured to the backing or base plate 8 by means of screws, which pass through slots in the support and permit of adjustment of movement of the roller 25 in relation to the rack 19.

In order to prevent the wicket from being elevated except by the pedal, a lock is provided. This lock, as shown, consists of a friction-clutch, which engages with the rod 6. The clutch is shown as formed of a plate 27, which has a central opening through which passes the rod 6. This plate is secured by a screw 28 to the bracket 7. The opening through which the rod 6 passes is sufficiently large to make a loose lit, and the connec tion with the plate 27 and screw 28 is sulliciently loose to permit some movement of the plate upon the bracket. This plate will serve the purpose of a clutch to prevent the elevation of the rod 6 except by the pedal. It is pressed upward into engagement with the rod by means of a spiral spring 29, which surrounds the rod and also engages with the plate 27. The other extremity engages with a second bracket 30, through which the rod 6 also asses. As shown in the drawings, the brac iets 7 and 30 are formed of one piece of sheet metal bent to the shape illustrated to form a support for the clutch-plate 27 and the end of the spring 29.

The plate 27 is depressed by means of a dog-31, which is carried in bearings on a standard 32, which in turn is supported by the bracket 7. One end of the dog engages with the clutch 27. The other end comes in contact with a cameplate 33, carried by the rod 20, by means of which it may be tilted. This cam-plate 33 extends up above the bracket 7 only a short distance and ends at a point below the dog 31 when the plate 33 and rod 20 are in the lowermost position. This lowermost position is determined by a stop 341, which may be in the form of a pin passing through the rod and engaging with the bracket 7. It will be seen that when the parts are in position shown in Fig. 3 the dog 31 will merely rest on the top of the camplate 33, allowing the spring at 29 to elevate the clutch-plate 27 and canse the latter to lock the rod 6 against vertical movement. When the rod 20 is elevated, the dog 31 will be engaged by the top of the cam-plate '33 and tilted, depressing the clutch-plate 27 and permitting the rod 6 to be elevated.

The operation of the device is as follows: Ordinarily checks, pass-books, &c., are passed over the counter 2 and under the wicket 1. Should it be necessary for any purpose to increase the size of the windowopening, the teller depresses the pedal 21. This elevates the rod 20 and rack 19, rotating the pinion 17. It also elevates the cam 33, depresses the clutch 27 through the agency of the dog 31, and will permit the elevation of the rod 6 and with it the wicket 1. The pinion 17 is free to rotate a certain distance before the lingers 1S and 13L come into engagement. This distance is sufficient to permit the elevation of the cam 33 a sufficient distance to cause a disengagement of the clutch 27 with the rod 6. As soon as this has occurred the fingers 13 and 1Sa will come into contact with each other and the sprocket 11 will be rotated by the rotary movement of the pinion 17. This will elevate the chain 9 and rod 6 and with it the wicket 1. The wicket will remain open so long as pressure is applied to the pedal 21. Upon the teller removing pressure from the pedal the weight of the rack 19, rod 20, and cam 33 will be sufcient to quickly overbalance the other side of the pedal. The parts will immediately descend to the pesition shown in F ig. 3. This will not rotate the sprocket 1 1, for the reason that the pinion 17 will be free to rotate in the other direction for nearly a complete revolution before the fingers 1S and 18a will again come in contact. Pressure having been removed from the pedal 21 and the rod 20, cam 33, and rack 19 having been allowed to descend, the wicket will descend also, but not so rapidly, as it is counterbalanced to some extent by the counterweight 14. The clutch 27, however, will be put into action the moment the cam 33 has entirely descended. Consequently the wicket will be locked against further open movement. Should an attempt be made to open the wicket after the pressure has been removed from the pedal 21, such attempt will be unsuccessful, because the wicket will be guarded against open movement by means of the clutch 27. The clutch 27 will act noiselessly and yet will be effective at any point of the vertical movement of the rod 6.

In order to prevent a too sudden jar upon the closing of the Wicket, the lower end of the rod 9 may be provided with a rubber button 35, which is adapted to engage with a bracket 36, carried by the support S.

By mounting the lifting and locking mechanism upon the support 3 the parts may be adjusted before being put in place. It is not absolutely essential that the rod 6 engage with the center of the cross-bar 5, although the nearer it is to the center the less liability there will be of jamming in elevating the wicket.

By the construction described a single ele- Szo IOO

IIO

i vating device is employed. This has the advantage over my previous patent, which employs a duplex arrangement engaging with each side of the wicket. I find in practice that this is not necessary, and a single chain, clutch, &c., may be employed with equal success.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a tellers window, the combination with the wicket, of means for` raising the wicket, such means including a rod, and a lock for the wicket, such lock including a friction-clutch engaging with the rod.

2. In a tellers window, the combination with a wicket, of lifting and locking means for the wicket, the said lifting and locking means being carried in oto upon a backingplate, in such a manner as to Jform an entirety adjustable independently of the wicket, and connections between the lifting and locking means and the wicket.

3. In a tellers window, the combination with the Wicket, of a rod for lifting the wicket, a chain and sprocket for lifting the rod, a pinionand a rack for rotating the pinion, and means for moving the rack, a cam moved by the rack, lost-motion connections between the pinion and sprocket, a friction-clutch adapted to engage with the rod, and a dog adapted to engage with the cam and release the clutch.

4. In a tellers window, the combination with a wicket, of means for moving the wicket and means for locking the wicket, such means includinga rack, means for moving the rack, a rod, means actuated by the rack for moving the rod, and a friction-clutch engaging with the rod, and a dog actuated by the movement ofthe rack for disengaging the clutch, and connections between the rod and wicket.
