WINDOW-REGULATING MECHANISM.

Application filed September 5, 1924. Serial No. 736,014.

To all whom it may concern:

Be it known that I, ANGELO ROBERT CLAs, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State a is to so construct the interconnecting means that it may be cheaply made and easily assembled, and when assembled will rigidly hold the parts in position and afford a large bearing areafor the member in its support. Thus the invention provides an exceedingly eflicient construction that may be made at a very low cost of production, since it provides a means whereby the construction may be made by automatic machinery, dies, presses, and the like, and may be readily assembled by the use of cheap labor.

The invention may be contained in structures of difierent forms and for the purpose of illustrating a practical application of the invention, I have selected a preferred embodiment of the invention as an example of such structures and shall describe it hereinafter. The structure selected is shown in the accompanying drawings.

Figure 1 of the drawings illustrates a side view of a member used in raising and lowering a window of the type commonly found inclosed automobiles. Figure 2 is a view of a section taken on the line 2-2 indicated in Fig. 1. Figure 3 is a perspective ,view of dis-assembled parts of the means for pivotally supporting the member and for connect- 'ing the member to a coun terbala-ncingspring. Figure 4 illustrates the counterbalancing spring in position for counterbalancing the member. Figurevo is a view of a section taken on the line 5-5 indicated in Fig. 2, the spring being omitted. The view in Fig. 5 is somewhat enlarged as compared to the View shown inFig. 4.

Fig.1 illustrates but fragmentary parts lVindow-Regulating of the members of the construction with which the window regulating mechanism coacts and to which it is connected to perform the functions for which it is designed. The particular window regulating mechanism illustrated in the drawings comprises a gear segment 1 that may be oscillated by the rotation of any suitable pinion. The segment 1 is provided with an arm 2 that is carried about the pivot of the segment 1 by the movement of the segment. The outer end of the arm 2 is connected by any suitable means to the window 3, which is to be raised and lowered. The window 3 is provided wih a bar 4 that covers the lower edge por-. tron of the window 3 in thesmanner well force used to raise and lower the window and sustain the window in any position in which it is placed, is transmitted through a I unitary oscillatory structure comprising the gear segment 1 and the arm 2, and that the pivotally supported means must be exceedingly rigid and durable in order to produce an efiicient window raising and lowering mechanism.

The gear segment 1 is pivotally connected to its support so as to afiord a large bearing area for the oscillatory movements of the gear segment and a stud is provided for in terconnecting the oscillatable part with the counter-balancing spring that, notwithstanding the magnification of the force of the load produced by the length of the arm as measured'between the point of contact of the roller 5 with the window to the center of the stud, will sustain the window although the stud is cheaply made and readily assembled. It is exceedingly rugged and will withstand the severity of the strains to the segment 1. The segment 1 may e suported by a sheet metal depending member having a raised-central portion 8, the width of the raised central portion 8 being preferably as great as the diameter of the depressed circular portion 6. Thus the depressed circular portion 6 has bearing contact with the raised central portion 8 of the cylindrical portion 11 may be inserted in.-

the opening 9 and the surfaces of the flange 10 ,and the depressed cylindrical portion 11 will afl'ord relatively rotating bearing surfaces. A disc 12 may be located on the cylindrical depressed portion 11 and so as to extend over the edges of the flanges 10. The disc 12 is secured to the depressed portion 11 so that the edge of the flange 10 will be engaged by the peripheral portion of the disc 12. Thus the segment 1 will be securely held in position for oscillative movements about its axis.

The weight of the window is counterbalanced by a convolute spring 13 which is connected to the segment 1 and to the supporting member 7. In order to connect the spring 13 so that it will sustain the weight of the window which is transmitted through the arm 2, and at the same time secure the bearing surfaces of the segment and the supporting member 7 rigidly in their relative positions for rotatably supporting the segment 1, a stud 1 1 is secured to the seg' ment 1 and the spring 13 is connected to the stud 14*.- The stud 14 is formed of sheet metal. It is made in the form of a thimble having slots 15 on opposite sides thereof. through which an end portion of the spring 13 extends, and when the spring 13 is placed under tension, its end portion vill be located in the stud 14. The other end of the convolute spring 13 may "be connected in any suitable way to a stationary part. It is preferably connected to the supporting member 7, and so that rotation of the segment 1 to further distort the spring will be resiliently resisted by the spring in themaiiher well known in the art. In order that the stud 14: may be rigidly connected, not only to the balancing spring but also to the segment to securely retain it in rotative position, the edges of the thimble-like stud are provided with fourv projecting tongues 16, that may be inserted through slots 17 located in the disc 12, and slots 18 located in the segment 1. The

slots

17 and 13 have a cross-sectional area substantially the same as that of the tongues 16, and so that the tongues will tightly fit within the slots when they are inserted therein. When the con-- nection is made the tongues are inserted in the slots and the ends of the tongues are split as shown in Fig. 2, so as to cause the outer end portions of the tongues to spread and thus rigidly engage not only the disc 12 but particularly the portions of the segment 1 located at the ends of the slots 18 The inner end portion 19 of the convolute spring is inserted through the slots 15 to engage the stud. The outer end portion 20 is connected to a stationary part of the structure such as the depending supporting member 7. This is done after the spring has been bent to sustain at all times the weight, or a material part of the Weight of the window, in the manner well known in the art. In the form of spring shown. the outer end portion 20 is bent semi-circularly to form a hook, whereby engagement may be easily made with the supporting member'7. In order to provide a rigid anchor for the fixed end of the spring, the lower end of the supporting member 7 may be provided with a flange 21, preferably curved to conforn'i to 'the segment of the cylinder having an axis that extends through the center of rotation of the segment, and recesses 22 am formed in the flange. The hooked end of the spring 13 may be located in any one of the recesses according to the degree that it is desired to distort the spring from its normal form. The plurality of engaging points for the outer end of the-convolute spring provides a means for adjusting the yielding resistance, and consequently the counterbalanclng effect of the spring. The flange 21 is provided with a bead 23, whereby the flange is greatly reinforced and enables the flange to sustain the unusual pressure to which the flange is subjected by the spring. The constructions of the spring 13, the stud 14, and the anchoring flange 21. are such that the spring may be readily positioned so as to resiliently sustain the arm 2 as against right hand rotation. or in position such that it may resiliently sustain the arm 2 as against left hand rotation, and adjust-- ment made in either case.
