Patented Apr. 10, 1934 .PATENT OFFICE REGULATOR FOR WINDOWS AND THE LIKE Burton S. Floraday, Toledo, Ohio, assignor to The Dura Company, Toledo, Ohio, a corporation of Ohio Application July 6, 1931, Serial No. 549,062 4 Claims. (01. 268-126) The invention relates to regulators for windows, Windshields and like closures, and has for some of its objects to so construct the'mounting plate that it is reinforced to withstand the stresses to which it may be subjected; and to so form the mounting plate that it has integral nuts for receiving the threaded members used in securing the mounting plate to its support. Other objects are to provide the regulator with a pair of lifter elements, which are mounted on the mounting plate, and to form the mounting plate with single integral means for retaining the lifter elements in place; and to provide a single counterbalancing means connected to the lifter elements.

These and other objects of the invention will become apparent from the following description, taken in connection with the accompanying drawing, in which Figure 1 is a side elevation of a regulator, showing an embodiment of my invention;

Figures 2 and 3 are cross sections, respectively, on the lines 2-2 and 3-3 of Figure 1;

Figure 4 is a cross section on the line 44 of Figure 1, showing the manner of securing the mounting plate to its support. 7 Y

The regulator has the sheet metal mountin plate 1, which carries the lifter elements, and the mechanism for actuating these lifter elements. This mounting plate has the central portion 2, the side marginal portions 3 and 4, and the end marginal portion 5. The side and end marginal portions are laterally offset in the same direction from the central portion and are connected to this central portion by the'transverse portions 6. The side portion 3 terminates short of the end portion 5 so that the central portion 2 is a gen- With this construction, it will be seen that the mountingplate is effectively reinforced mainly by reason of the transverse portions 6, so that it may be formed of relatively light gauge sheet metal and withstand the stresses to which it may be subjected.

The side marginal portions 3 and 4 and the end marginal portion- 5 are provided withnuts for receiving threaded members, such as the screws '7, to secure the mounting plate to its support, which in the present instance is shown to'be a sheet metal plate 8 having frusto-conical flanges 9 adapted to receive the heads of the securing members. These nuts are integral with the mounting plate and each is formed by piercing tfi'fnounting plate blank at the proper point to form the substantially circular opening 10, after which the portion of the blank surrounding the opening is stamped to form the integral boss 11 with the opening substantially concentric with the axis of the boss. The edge 12 bounding the opening is then severed at 13 by a suitable punch and the severed ends of this edge are oiTset the proper distance to take care of the pitch of the threaded member 7. Each boss 11 extends from the marginal portion of the mounting plate in the same direction as the transverse portion 6 and away from the support 8, so that when the threaded member 7 is tightened in place it places the boss under compression and this boss being resilient functions to'lock the threaded member from rotation.

Two lifter elements are mounted upon the central portion 2 of the mounting plate between the side marginal portions 3 and 4 and at the side opposite the side marginal portions. Each of these lifter elements comprises the sheet metal gear member 14 and the sheet metal lifter arm 15, which latter is fixedly secured at its inner end to the former and is provided at its outer end with a suitable device for attachment to the closure, such as a window or a windshield. The gear members are preferably oi the same diameter and have the peripheral teeth 16 and furthermore these gear members are so mounted that their teeth mesh. For mounting each lifter element I have formed the mounting plate with the transverse cylindrical flange 17 and I have provided a shaft which is formed of the sheet metal cup 18 and the polygonal shaped rivet 19. The portion of the cup journalled in the cylindrical flange 17 is of reduced diameter and the rivet 19 extends through the base of this cup and the lifter element including the gear member 14 and the lifter arm 15 and fixedly secures the lifter element to the cup so that both are rotated as a 'unit.

It will be seen that one of the lifter'elements actuates the other through the meshing gear members. For actuating the driving lifter element, I have mounted upon the central portion 2 of the mounting plate and at the same side as the lifter elements the gear 20 and the pinion 21, which are fixed to each other and are so arranged that the pinion 21 meshes with the gear member 14 of the driving lifter element. The gear 20 and the pinion 21 are mounted upon the grommet 22 which is journaled upon the cupshaped boss 23 formed integral with the mounting plate. The assembly of gear, pinion and grommet is secured in place by means of the sheet metal plate 24, which is fixedly secured to the end or" the boss by the rivet 25. This plate overlaps the assembly and further has the resilient tongue 26 which overlaps and engages the gear member 14 near its zone of meshing with the pinion 21.

For actuating the gear 20, I have provided the driving pinion 27 which meshes with this gear and is adapted to be driven through suitable irreversible drive mechanism 28 from a crank or a handle. This irreversible drive mechanism may be of usual construction having the spiral spring wire 29 which normally expands into frictional engagement with a stationary cup to lock the operator in its adjusted position and which is adapted to be contracted upon movement of the handle or crank to become released from the cup and permit operation of the regulator through the driving pinion. The cup 30 which houses this irreversible drive mechanism and the inner face of which is engageable with the spiral spring wire 29 is formed integral with the mounting plate.

For retaining the lifter elements in place and also retaining their gear members in mesh, I have provided the single integral tongue 31 stamped out from the central portion 2 of the mounting plate and overlapping and engaging the gear members 14 near their zone of meshing.

32 is the counterbalancing spring for the lifterelements. This spring has the spiral end portions 33 and the straight connecting portion 34. The spiral end portions encircle the enlarged end portions of the cups 18 and terminate in the straight ends 35 which extend through the diametrically opposite slots 36 in these enlarged end portions to anchor the ends of the counter balancing spring to the lifter elements.

What I claim as my invention is:

1. In a regulator for a window or the like, the combination with a sheet metal mounting plate having a cylindrical flange, a lifter element mounted upon said plate at one side thereof and a counterbalancing spring at the other side of said mounting plate, of a shaft comprising a cup journalled in said flange and connected to said counterbalancing spring, and a member fixedly securing said lifter element to said cup.

2. In a regulator for a window or the like, the combination with a sheet metal mounting plate having an integral cup-shaped boss, of a lifter element journalled upon said plate, means for actuating said lifter element comprising a member journalled upon said boss, and a member fixedly secured to the end of said boss and overlapping said member.

3. In a regulator for a window or the like, the combination with a mounting plate having a journal portion, of a lifter element journalled 'upon said plate and having a gear member, a

second gear member journalled upon said journal portion and meshing with said first mentioned gear member, and a member fixedly secured to said journal portion and overlapping said second mentioned gear member and engaging said first mentioned gear member.

4. In a regulator for a window or the like, the combination of a sheet metal mounting plate having an integral cylindrical flange and having an integral cup-shaped boss spaced from said flange, alifter element mounted upon said plate at one side thereof, a counterbalancing spring at the other side of said mounting plate, a toothed member connected to the lifter element and mounted upon a shaft having a cupped portion journaled within the cylindrical flange and secured to the counterbalancing spring, and a driving toothed element journaled upon the boss and meshing with the toothed element aforesaid BURTON S. FLORADAY.
