Claims.

This invention relates particularly to window regulators for use in Fisher No Draft ventilating windows. The Fisher No Draft ventilating system is described and, claimed in the Fisher Patent No. 2,048,605. In these ventilatingsystems, it is customary to use either a fixed division pillar which remains in position regardless of the position of the panels, or else to use a stile or channel on the sliding panel which slides up and down with the sliding panel. In the Fisher patent,

an H channel is disclosed and the division line between the two panels inclines rearwardly from bottom to top. Hence, when the sliding panel is first lowered, the stile withdraws from engagement with the front swinging panel. This arrangement is shown and claimed in the Simpson Patent No. 2,087,821. Another arrangement which is quite extensively used utilizes a vertical stile on the sliding panel but of H cross section. When the sliding panel is lowered, the weatherstrip on the stile rubs the edge of the swinging panel all the way down and is open to the objection that it wears the strip and also, in a measure, interferes with the lowering operation.

'It is the purpose of the invention about to be described to overcome these diificulties and yet utilize a vertically disposed stile. This is accomplished by an arrangement whereby the regulator at the beginning of the lowering operation causes the sliding panel to move a slight distance to the rear to separate the two panels and then the regulator operates to lower the sliding panel.

In the drawings:

Fig. 1 is an elevation of the window regulator in connection with fragmentary parts of the two panels showing the panels in their fully closed position.

Fig. 2 is a similar view showing the panels after they have been separated by ahorizontal movement of the sliding panel.

Figs. 3 and 4 are sections on the corresponding section lines of Fig. 1.

Figs. 5, 6 and 7 are sections taken on the corresponding section lines of Fig. 2.

Fig. 8 is a section taken on the line 3--8 of Fig. 1.

Fig. 9 is a section taken on the section line 9-5 of Fig. 2.

Figs. 10 and 11 are details showing the two positions of the major and minor sectors.

I designates the swinging panel of the Fisher No Draft ventilator, 2 the sliding panel. However, this sliding panel is capable of a small horizontal movement as well as a vertical movement.

This movement can be observed by comparing the position of the two panels in Figs. 1 and 2.

The window regulator comprises a sector type of regulator of a common type. This includes a clutch, not shown, but contained in clutch case 3, a driving pinion which has teeth that mesh with the usual toothed sector 5.

This sector has the usual lifting arm 6. This lifting arm is preferably provided with an additional arm 1, the lower end of which travels in the horizontal guide 8 and the upper end has a roll that travels in the horizontal guideway 9 on the bottom of the sliding sash 2. This is an improvement described and claimed in Graf Patent No. 2,010,075.

The sliding panel 2 is provided with an H section channel N). This is a vertically disposed channel and, when the panels are closed, this channel straddles the rear edge of the swinging panel and locks the two together so as to make a near air-tight seal and, at the same time, prevents one prying the swinging panel open to get into the car from the outside.

My improvement consists of an arrangement whereby the sliding panel in the initial lowering operation moves first rearwardly from the posi tion shown in Fig. l to the position shown in. Fig. 2. This is accomplished by a slight relative movement between the minor sector H and the major toothed sector 5.

Referring to Figs. 10 and 11, it will be seen in Fig. 10 that a tooth ii on the minor sectoris engaged between two teeth on the driving pinion 4. When the driving pinion is turned clockwise, the minor sector It will move a short distance counterclockwise until the lip IS on the minor sector moves from the position shown in Fig. 10 to that shown in Fig. 11. In this latter position, the lip strikes the edge M of the major sector 5. The pin l5 on the minor sector engages in a notch it in the arm ll. This arm I! has a hooked end it provided with a notch it that engages the pin 2Q on the bracket 29 attached to the bottom of the sliding panel. When the driving pinion is first turned counter-clockwise in Fig. 1, it first rotates the minor segment ll clockwise. The pin 55, engaging in notch GEE, pushes arm H to the right and arm ll, with its notch 59 engaging over pin 28, pushes the sliding window rearwardly from the position shown in Fig. l to the position shown in Fig. 2, thereby separating the two panels a slight distance. This distance is shown by comparing Figs. 1 and 2 and Figs. 8 and 9.

The sliding arm ll has slots 22 and 23 through which pins 24 and 25, attached to the window regulator plate 26, engage so as to guide the arm in its sliding movement. When the pin l5 has passed from the position shown in Fig. 1 to that shown in Fig. 2, it reaches the mouth of the slot l6 and the flared opening 2'! of the slot now permits the pin to clear the arm I! as it moves upwardly in an arc whose center is the pivot point 28 of the major sector 5 after the two sectors come together and move as a unit when the lip 13 engages the edge 14 of the major sector. The two sectors are held together on the fulcrum pin 29. A torsion spring 30 biases the minor sector and tends to bring the lip H3 in contact with the edge M of the major sector.

In order to hold the major segment in a determined position when the sliding panel is in its uppermost position, a latch 3! spring-pressed by spring 32 and pivoted on the window regulator plate is provided. On Figs. 1 and 2, the latch is seen contacting with the upper edge of the major sector 5. As the small sector H makes its limited relative movement with respect to the large sector, the struck out cam lip 33 cams this latch out of the way as will be seen by comparing Figs. 4 and 5. The major sector 5 is now free to move past the latch. This latch serves to hold the major sector in a definite position so that, at a given point in the lifting or descent, the relative movement can take place between the two sectors. This cam lip 33 engages in a notch 34 in the major sector 5 so that, when the two sectors start to move together (as shown in Fig. 5), the cam lip 33 has cammed the latch 3| out of position so that the upper edge M of the major sector may now pass the latch 3|. On return movement, as soon as the upper edge of the large sector passes the latch, the latch drops behind this edge, as shown in Fig. 4.

It is not broadly new to provide a window regulator in connection with the Fisher No Draft ventilating system which will first separate the panels by a movement of the sliding panel horizontally and then moving the sliding panel downwardly. A regulator of this type is shown and broadly claimed in the Kegler Patent No. 2,152,-

055. Nor is the use of my regulator necessarily confined to a ventilating system, such as the Fisher No Draft for the regulator per se is useful wherever a window panel has to first move horizontally and then downwardly and viceversa.
