MECHANICAL `MOVEMENT.

Application illed ctober 26, 1923. Serial No. 670,980.

This invention has for its objecta particularly simple and efiicient mechanical movement articularly adapted to I 'aise and lower t e windows, such as the windows of automobiles. More particularly, it has tor its object a mechanical movement in which the rotating driving element is normally locked and is actuated by the rotatable'handle which operates to release the driving 1o element of the lock turning the driving element and again engages the lock, which driving element is turned up by a turning movement of the handle, such as would naturally be given it to turn the driving element only.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed. o

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in al1 the views. Figure l is an elevation of this mechanical movement, the contiguous part of the means to which the movement is transmitted, as a window sash being show n.

' Figure 2 is an edge view looking downwardly, of parts seen in Figure 1. Figures 3 vand 4 are enlarged sectional views taken on the plane of line 3 4, Figure 1, the parts being'shown in normal position, Fig. 3, and in shifted position in Fig. 4. Figure 5 is a sectional view, parts being omitted, on line 5 5, Fig. 4.

ber.

Figure 7 is a view similar to Figure 3,-

of another form of this invention.

This mechanical movement comprises generally a gear member, a lock member meshing with the gear member, one of such members being shift-able axially into and out of engagement with the other member, actuating means movable about an axis and connections by which the shiftable member is shifted axially out of mesh with the other member during the initial part of the rotary movement of the handle prior to the transmission of motion by the gear member and, also, is shifted back into mesh with the other element at the end of each Operation of the handle.

This mechanical movement is particularly windows,

Figure 6 is a detail view of the lock memapplicable for raising and lowering the such as the windows of automobiles, and 1 designates the window pane which is movable in any Well known manner in .guides in the door of the vehicle and which usually has a sash rail or a reinforcing strip 2 at its lower end.

3 is a suitable supporting plate for the mechanicalv movement, this plate being mounted within the door of the automobile on a transverse frame member placed in the door for supporting the window operating mechanism, the plate 3 being secured in any suitable manner.

The driving gear element in this embodiment of my invention, includes a gear 4, which meshes with thegear element as a tooth segment 5 mounted on a suitable shaft or center 6 supported by the plate 3, the

motion being transmitted from the segment' to the window through an arm\7 formed integral with the segment 5 or mounted on the shaft 6 and connected to the segment 5 to move, as-a unit, therewith, this arm 7 having a roller 8 at its outer end bearing against the lower edge of the window, that is, against the rail or strip, 2.

.A suitable counterbalancing spring 9 is connected at one end to the arm 7 and at its other end* to a bracket 10, secured to the plate 3. Obviously on turning the segment 5 by turning the gear 4, the arm 7 will be raised or lowered and thus raise or lower the window 1. v

In order to hold the Window 1 at various elevations, means is provided for locking the gear 4 from rotation in any position 'of the arm 7 or the Window 1, this lock being here shown as a toothed member having a tooth or teeth normally meshing with the gear member 4 and one of these members being shiftable axially out of mesh with the other preliminary and subsequent to each turning of the gear 4 and hence, shifting of the window 1.

As here illustrated, the lock is stationary and the gear 4 shiftable axially, the lock comprising a ring 11 fixed to a supporting plate 3 concentric with the gear 4 and having one or more teeth 12 meshing or interlocked with the teeth of the pinion 4, as shown in Figures 1 and 3.

The means for actuating the gear 4 for shifting it axially comprises a handle 13 in the form of a crank movable about the axis -of the gear 4, and connections between the crank and the gear 4. These connections 1nbeing connected together by a lost motion 'connection and having coactlng cam faces i arranged to shift the part 15 axially while the lost motion is being taken up during the 'initial part of the movement of the handle 13 and, also during the last part of the movement of the handle 13 after'the window has been raised or lowered.

As here shown, the part 14 is secured to the handle 13 at the hub thereof in any suitable manner and comprises a head and a stem 16 imbedded in the handle, the head being rotatably mounted in a sleeve or hub 17 secured in the plate 3, this head having inclined iiat cam faces 18 on diametr'ically opposite sidesv thereof, and also, having a. iiat portion 19 arranged ma diametricall'y extending passage 20 in the member 15., this passage 20 diverging Jfrom the center 1n the member l15 toward the periphery thereof, in order to permit the rocking of the member 15 and the lost motion between the members 14 and 15.

The member 15, also, ycomprises a head journalled in the hub 17 and t-he stem on which the gear 4 is mounted, the slot 2O being formed in the head and in the stem, also, the head in the part 15 is formed with inclined faces 21 complemental to the faces `18 of the driving part 14.

Obviously, due to the slot or passage 20, the movement of the handle 13 rotates the driving part 14 rela-tively to the part 15, during such relative rotation, the cam faces 18 act on the cam faces 21 of the part 15 and shift the part 15 and the pinion or gear 4 axially out of mesh with the lock 11, so that the continued rotation of the handle rotates the gear 4 and segment 5, and actuates the arm v The shifting of the part 15 is against a retaining spring 22 and thus at the end of the turning movement of the handle 13 or when the operator releases the handle 13, the spring again reacting on the part 15 will thrust it tq the left from the position shown in Fig. 4to that vshown in Fig. 3 and' in so doing turns the part 14, if the teeth of the gear 4 are not in line with the teethgof the lock 11, and shift-s the gear 4 into meslfwith the lock 11. y j

The hub 17 is provided on a basev plate 23 suitably secured to the plate 3 and the parts 14, 15, within-the sleeve 17 are held from displacement by a cap A24 threading on the sleeve 17 between the hub of the handle 13 and the end of the sleeve. The spring 22 is the gear, and a part actuated by the located in the sleeve 17 between the head of the member 15 and a shoulder at the inner end of the sleeve. f

The lock in order to be adjusted so that its teeth mesh with the gear when the window is in closed position, is so formed that it can be shifted about its axis and then permanently secured in its fixed' position, as when the hub is formed with arcuate slots 30 concentric with itpfor receiving the screw 31 by whichv the lock is secured to the base p ate.

As seen in Figure 7, the cap, instead of threading on a sleeve, may be formed as shown at 32 in which the sleeve is secured to the base plate, by fastening members extending through an annular flange 33 at the end of the Sleeve and into a base plate. Also in Figure 7, the hub of the handle partly encloses the sleeve 17 and the handle is held in position on the stem 16HL of the part 14a by a screw 34. Also, the spring 225l is a. fiat spring mounted outside of the driving gealand ci' the sleeve and is xed at one end to the base plate and thrusts at its other end against the outer face of the gear.

This mechanica-l movement is particularly advantageous in order to operate it and, also to raise and lower the window and to hold the window at any position, for it is merely necessary to turn the handle or crank and the locking means locks and unlocks automatically.
