10 Claims. (01. 268-119) This invention relates to a combined window and other types of closures and window glass operator and lock. panels.

The object of this invention is to produce a The window operator comprises a casing 6 combined window operator and lock which is which maybe die cast or otherwise formed.

The swinging panel is bolt 26. The bolt" is guided in a sleeve 21 mounted in a frame 5 which is fixed to, and supth Opening in e flange 23 01 the ported upon, a vertical shaft 4. The panel 3 plate 1 and through an opening in the base of is thus arranged to swing in the well-known the Weatherstrip channel 8. The window frame 5 manner about a vertical axis between its front 5 is provided with an opening 29 which serves and rear edges to open and closed position. Alas a keeper into which the bolt 26 is projected though this combined window operator and lock to lock the window panel 3 in closed position.

. is shown with a swinging panel, it is understood The bolt 26 is provided with a shoulder 30. A that it is equally adaptable for use with sliding coil spring 3| is mounted between the shoulder 55 and the flange 23 of the plate I and normally tends to urge the bolt 26 to retracted position.

The operation of this device is as follows:

turning of the worm l3 to cam the worm I3 from the position shown in Fig. '4 to the position shown in Fig. 5. Since the worm I3 is fixed on the shaft l4, the shaft shifts axially to the right as viewed in Fig. 2, further compressing the spring l8, Fig. 5. As the shaft l4 and worm shift axially the worm engages the end 20 of the lever l9, swinging the same counter-clockwise, Figs. 3 and 4, which, through the link 22 swings the bell crank 23 counter-clockwise, thus projecting the bolt 26 into the keeper opening 21 and compressing coil spring 3|. This looks the window panel 3 in closed position. If crank I1 is now turned to open the window, the initial turning movement of the crank I! will cause the worm l3 to be cammed outwardly by the worm gear 9 until the worm l3 abuts the plate 1 as at 52, thus permitting the coil spring 3| to retract the bolt 26 from the opening 29 and acting through the bell crank 23 and link 22 swing the lever I9 clockwise so that the end 20 is held against the shoulder of the worm l3. After the worm reaches normal position abutting against the plate 1 as at 52, shown in Fig. 4, further turning of the worm will rotate the worm gear to swing open the window panel 3.

A modified form of this combined window operator and lock is shown in Figs. 5 through 9. In this form of the invention the worm gear 9 is driven by the worm 4J which is splined upon the shaft 4!. The shaft 4| is journalled in the casing 8 in the same fashion as the shaft l4 and also turned by the usual crank handle H. A lever 42 is pivotally mounted upon the base of the casing 6. One end of the lever is pivotally connected to the link 22 as at 43 and the other end of the lever has a swivel connection as at 44 with a plate 45. The plate 45 has an opening 46 through which the reduced end 41 of the shaft 4| is threaded so that the plate 45 can shift lengthwise along the reduced end 41 of the shaft 4|. A coil spring 48 is threaded over the shaft 4| and mounted between the plate 45 and the wall of the casing 6 so that the coil spring normally urges and holds the plate 45 and worm 40 in the position shown in Figs. 7 and 9.

In this form of the invention the spring 48 exerts suflicient tension so that during the normal closing and opening of the swinging window 3 the driving torque will be transmitted from the worm to the worm gear to open and close the window. As soon as the swinging window panel reaches closed position the worm gear 9 cannot turn further. Further turning of the worm 40 causes the worm gear to act as a cam and cams the worm 40 axially along the shaft 4| from the position shown in Fig. 9 to that shown in Fig. 8, thereby compressing the spring 48 and at the same time shifting the plate member 45 along the reduced portion 41 of the shaft from the position shown in Fig. 9 to that shown in Fig. 8. This movement of the plate 45 causes the lever 42 to swing counter-clockwise and thereby through the link 22 and bell crank lever 23, project the bolt 26 into the keeper opening 29 in the window frame to lock the swinging window in closed position. When the crank handle I1 is turned to open the window the initial turning movement of the crank handle will now cause the worm gear 9 to cam the worm 40 outwardly, thus permitting the coil spring 48 to expand and force the plate outwardly or toward the right from the position shown in Fig. 8 to that shown in Fig. 9 so that the plate 45 follows the worm '40. This outward movementof the plate 45 is transmitted through the lever 42, link 22, lever 23, to the bolt 26'which is retracted from the keeper opening 29 to the full line position shown in Fig. 6. As soon as the worm 40 reaches the end of its outward travel, it abuts against the plate I as at 50. Further turning of the worm 49 will turn the worm gear 9 and open the swinging window.

A second modified form of the invention is shown in Figs. 10, 11 and 12. In this form the window glass frame 5 is bolted by the same type of link 22, bell crank 23 and bolt 26 as shown in the principal above described form of the invention. In this second modified form of the invention the worm 60 is fixed upon, or integrally formed with, the shaft 6| which is turned by the usual crank handle H. The shaft 6| is journalled in the casing 6 as at 62 and 63. The sup port shaft 4 for the swinging window glass 3 has fixed on its lower end the worm gear 64 provided with the usual gearfteeth 65. The lower end of the shaft 4 and worm gear 84 are provided with a bore 66 in which is journalled the shaft 61. The worm gear is also provided with an arcuate opening 68 extending outwardly from the bore 66 to the outer surface of the gear.

A swinging gear tooth 59 is keyed to the shaft 6'! by the key 10 and swingably mounted in the opening 68. This swinging gear tooth 69 retains the shaft 61 in the bore 66. A crank arm H, provided with a square opening, is secured on the square end 12 of the shaft 61 to swing with the shaft and acts through link 22 and bell crank 23 to project and retract the bolt 26.

In the operation of this modified form the position of the worm gear 64 when the window is fully open is shown in Fig. 11. If the crank handle is now turned to close the window, the worm gear 64 will turn in a counter-clockwise direction and the swinging window will reach closed position when the worm gear 64 reaches the position shown in Fig. 10. At this time it will be noted that the swinging gear tooth 69 has just reached the position where it meshes with the worm BI! and. the gear teeth 65 of the worm gear 64 have just passed out of mesh with the worm 60. Therefore further turning of the worm 60 in the same direction will cause the gear tooth 69 to travel along the worm in a counter-clockwise direction from the full line position shown in Fig. 10 to the dotted line position, thus swinging the shaft 61 and arm ll counter-clockwise from the full line position to the dotted line position. As the arm H swings from the full to the dotted line position, the link 22 is moved to the right as viewed in Fig. 3, thus throwing the bolt 23 into the keeper opening 29 to lock the swinging window. If the crank handle is now turned in the opposite direction to open the swinging window, the initial turning movement of the worm 60 will cam the gear tooth 69 from the dotted line position, Fig. 10, to the full line position Cal thereby through the shaft 81, arm II and link 22 retracting the bolt 26 from the keeper opening 29 in the framei. As soon as the gear tooth 69 in its clockwise rotation reaches the full line position, Fig. 10, it abuts the side wall 15 of the opening 88, thus transmitting the driving torque to the driven worm gear and swinging the worm gear 64 in a clockwise direction so that the worm gear teeth at the opposite end of the opening 68 are meshed with the worm 60 whereupon further turning of the worm' 80 will rotate the worm gear and swing the window to open position.
