new and useful Improvement in VVindow- Operators; and I do hereby declare the folaccompanying taken in connection with the drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the-same, and which said drawings constitute part of this application, and represent, in-

Figure 1 an outside view of a window operator with the sill and outside trimming removed. Fig. 2 a vertical sectional view of the same. Fig. 3 a view in front elevation of an operating handle and easing lowing, when in which it is mounted. Fig. i a longitudinal sectional view of the same. Fig. 5 a

view similar to Fig. 3 with the handle removed. Fig. (5 a similar view with the retaining plate removed, showing the ratchet held against rotation. Fig. 7 a similar view showing the parts free to turn in one direction. Fig. 8 a view in reverse elevation of the casing, showing the idler pulley and sprocket wheel. Fig. 9 a view of the inside of the vehicle door with the inner lining or covering removed, illustrating a modified form of my invention. Fig. 10 a vertical sectional view of the same.

This invention relates to an improvement in window operators, and particularly to means for operatin ".he windows of vehicle doors.

- height In the more general arrangement of windows a lon strap is attached to the bottom of the sash y which the, sash may be raised; -and unless the sash is raised to the full and so that the lower edge can he moved forward to rest upon the sill, means mustbe provided for holding the strap, and in many cases difficulty is experienced in raising the sash by a strap.

The object of this invention is to provide means forr'aising the sash by the turning of a knob or handle; and the invention consists in the'coiis'truction hereinafter described and particularly recited in the claims.

In illustrating my invention 1 have shown the lower' part. of a'vehicle door which may be ofany approved design, provided on op- Iposite sldes with grooved guides S, 4, in

which the window 5 is guided for movethe sprocket vertical movement into the lower part or pocket of the door. This window may have the usual wood or metal frame inclosing a glass, but as herem shown the glass is not inclosed by a frame but is provided at its lower edge with a metal flange 6 the upper edge of the outer face of which is turned over forming a hook 7, adapted to engage with the upper edge of what I term a fence 8 projecting upward from the sill 9. Connected with the flange 6 and extending downward therefrom is an arm 10 to which one end of a sprocket chain 11 is attached. This chain extends over a sprocket wheel 12, and its other end connected with a cord 13 which passes around an idler pulley 14 at the bottom rail 15 of the door, thence upward through an eye 16 at one side of the arm 10 over an I idler pulley 17 in line with the sprocket wheel 12; down around a pulley 18 on a lever 19 and upward to the mid-frame 20v 'where it is'firmly secured. On the cord 13 and secured by a pin &0 is a stop 21 which connects the cord to the arm 10 as it is drawn down, but permits the cord to move slightly upward without moving the arm and allows for taking up any slackness in the cord. The lever 19 is pivotally connected with a bracket 29. at one side of the door and connected with the lever and with the bottom rail 15 is a spring 23 the tendency of which is to pull the lever downward, and hence counterbalance to a certain extent the weight of the window 5.

in a casing 25 secured to the mid-frame 20. Extending through the hub is a shaft 26 to the outer end of-which a knob or handle 27 is secured. At its inner end the shaft is formed with radial lugs 28 setting into recesses 29 in the inner face of the sprocket wheel12. The recesses are wider than the lugs so that a certain amount of independent movement is permitted before the shaft will wheel. hub is a ratchet 30 having double-face teeth 31 and connected with a D shape portion 32 of the shaft is a pawl tripper 33 adapted when turned to lift either of the pawls 34., 35, mounted 9n the cylindricalportion 36 of the casing 25 to respectively engage opposite faces of the teeth 31. Set into the outer end of casing 25 is a retainingplate 37 to this plate is and secured The sprocket wheel 12 is secured to a sprocket wheel hub 24 mounted Riveted to the.

the cylindrical portion 86 of the a spring friction yoke 38, the 1-10 fingers of which embrace a. bushing 39 mounted on the D shape portion 32 of the shaft and adapted to turn therewith. The

function of the lugs 28 and recesses 29 is to permit the shaft to have a slight movement independent of the ratchet-wheel to allow the tripper to disengage one of the pawls from the ratchet.

Whenthe sash is in the raised position as shown in Figs. 9 and 10 of the drawings, the lower edge will be engaged with the fence 8 or the lower edge may rest upon the sill 9 in the usual way. In either event it will be necessary to slightly raise the sash so as to release the lower edge and bring it into alinement with the guides 3 and 4. Downward movement, however, will be stopped by the engagement of the pawl 3a with the ratchet 30; but if the handle be turned to the left, the tripper 33 will lift the "pawl 34 out of the path of the teeth on theratchet as seen in Fig. 7 due to the fact that the tripper may have a slight movement independent of the ratchet owing to the provision of the wider recess 29, it being understood thatthe number of teeth on the tripper correspond to the numberof teeth on the ratchet; thus permitting the wmdow to be lowered byturning the handle, the spring 23 normally tending to pull the lever -19 downward so that the slack on the cord 13 will be taken-up. "The moment, however, the handle is released, the ratchet will be caught by the pawls 34 and 35 and further movement arrested. On the other hand, when the sash. is down, it may be raised by turning the handle to the right, .and in this movement the tripper will raise the pawl 35 so that the ratchet will freely pass the pawl 35. The sash will be locked at all points against movement other than that imparted by turning the handle, and the extent of.

movement of the lever is only half that of the window. Instead of using a sprocket wheel and chain, the cord 13 maypass over .a grooved pulley 41 mounted in thesame way as the sprocket. wheel 12 and the idlers l4 and 17 may also be omitted as shown in 9.and1 50 In a window operator, the combination; with a vehicle door having a pocket and e mid-frame, a window adapted to be moved up and down in said door, a wheel mounted with the window, and a balancing lever mou ed in the pocket below said window and ngagingwwith said HQXiOlG COBHGCtIOH.
