' OF TOLEDO, OHIO, A CORPORATION OF OHIO winnow REGULATOR FOR AUTOMOBILES Application filed April 25,
My invention has for its object to provide a window regulator that is particularly adapted for raising and lowering windows of conveyances, such as automobiles, and fi which is so formed that it may be readily constructed at a low cost of production and yet will be exceedingly efficient in its operation. The invention consists in forming a regulator largely of sheet metal parts that may be die stamped and assembled by cheap labor. V
The invention particularly provides a means for actuating a lifting arm that engages the lower edge of the window, and opcrates to lift and lower the window, and a clutch or looking member that automatically operates to secure the. arm in any position in which it may be located to support the window and prevent its descent either by a force applied to the window or by reason of its own weight due to, particularly, the shak- 7 ing or vibration caused by movement of the "vehicle over the road and wherein the locking and clutch member will cooperate through its interconnection with the arm to notonly support and maintain the window in the position to which it is raised or lowered,but will enable, by a very free and uniform movement or application of a substantially constant pressure, the operation of the window.
The invention consists more particularly in the simplification of the parts whereby they may be readily assembled and secured in their relative positions and whereby their co-a ction will be insured. The invention may be contained in window regulators that vary in their details of construction, and,'to illustrate a practical application of the in vention, I have selected a window regulator as illustrative of the various embodiments of my invention, and shall describe it hereinafter. .The window regulator selected is shown in the accompanying drawings. Fig: 1 is a side view of the window regulator. Fig. 2 is an edge view of the window regulator. Fig. 3 is an enlarged view of a section taken on the plane of the line 3 3 .indicated in Fig.1.

Fig. 6is a view of a section of the controlling parts of the regulator taken on a transverse plane and looking in a direction of the arrows marked 6-6 in Fig. 3.
p The window regulator shownin the drawings has a supporting plate or base 1 formed able spacing sleeves 4 may be located at the corners of the plate in order to properly space' the supporting plate'relative to the frame of the automobile and to give room for the oscillatory movement of the lifting arm of the regulator. Suitable rivets or bolts or screws may be inserted through the spacing sleeves to secure the support in position.
The window regulator is operated by a crank, in the manner well known, which is secured to a shaft 7 that is pivotally supported in the shell 8 and the supporting plate .1. The shell 8 is provided with a plurality of ears 9 and the platev l is provided with a corresponding number of openings 10 through which the ears 9 are inserted and turned over the outside of the plate 1 in order to secure the shell 8in' position. The central part of the shell 8 is provided with a flange 11 that surrounds the opening in the shell through which thecrank shaft 7 extends and forms a bearing for the support of the crank shaft. The plate 1 is provided with an opening 12.through which one end of tlie crank shaft extends and forms a second bearing for the crank shaft. The crank shaft 7 may be provided with a channel 13 in which a split bushing or brass collar 14 may be located, to form a bearing bushing for the crank shaft 7. A pinion v15 is supported on the crank shaft and a clutch or lockin member is'located within the shell8 for locking the pinion 15 from movement except when the clutch or look is first released in the operation of the crank shaft 7, whereupon means is provided for connecting the pinion to the crank shaft to rotate the pinion l5 therewith. In the form of construct-ion shown, a coiled spring 20,'norma1 ly having a diameter slightly larger than the inner diameter of the shell 8, is placed within the shellsozas'to frictionally engageztherinner surface of the shell. The ends 21.2und 22 of the spring are turned inwardly and form engaging parts for the releasement of .the spring from its frictional clutch engagement with the inner surface of the shell 8"when the spring ends are drawn to wind the spring in a direction that would reduce its diameter which operates to release it from its clutch engagement with the shell 87,. The inturned locking the spring by an increased frictional engagement upon rotation of the pinion 1'5. Rota tive 'fo'rce'is' applied to the pinion, other than one transmitted through the crank shaft, aswhen thelifting arm of the regu- Ilator is subjected to pressure either by a force applied to the window to lower the window, or by reason of the weight of the window. the spring is subject to the control @Of the crank shaft '7 and the pinion 15, the .one ;to release the spring 16 and the other to he locked thereby.. -hes'haf .Ta-nd'the pinion 15are vided with spiders 24 and 25 having fingers, preferably lthreein number, for engaging the iii-turned ends sigma .22 of the spring 20.. The fingers of the spider .24 on the sleeve 7 are so disposed .as to be located on the outer sides of the said inturned ends 21 and 22 while one or more of the fingers of thespider 25 are located between the inturned ends 21 and :22 of the spring 20, wherebynpon rotation of the crank shaft? the lingers ofthe spider :24 will engageoneor theother of the inturned ends; 21 or .22 to reduce the diameter of ithesp'iral springs 20, and a rotative .force applied to the pinion 15Iby thes'ector 16 will cause one or the other of the inturned ends 21 and 22 to be engaged and .rotationofthe .pirn'ion :w-ill be prevented. Furthermore, continned rotation of the crankshaft 7 will ro tate : thespiralspring 2,6 andcause one .or'the other of the inturned ends-21 .or 22 .to engage one of the fingers of the spider 25 :and thus rotate-the pinion 15 with the :crank shaft 5. which operates "the lifting arm .17 .to raise .or lowerthe window. I The bottom :of the shellt8 islprovided with raised portions 28 and .29 forming an annufifl lar depressed portion or channel .30. 7 It has adisc or plate 31 that is also provided, on its inner side, with recessed portions 32 .and 33, fornfingan annular depressed portion or annular channel 134 therebetween These parts correspond in location to the raised and deends 21 and 22a1so afford engaging parts for each propressed portions 28, 29, and 30 of the bottom of the shell 8. The raised portions29 of the shell and the raised portion 33 of the disc or plate 31 are located in proximity to the ends of the spiral spring 20 and maintain it in position in the lower end, or at the bottom, of "the shell '8, while the depressed portions 30 and 34 afford a clearance, one below the inwardly turned end 22 of the spring and the other above the inwardly turned 'end'2l of the spring. This insures a positive engagement as between the fingers of the spiders .24 and 25 and the inturned ends 21 and 22 of the spring and prevents the ends of the-springf'rom slipping over the ends of the fingers.
The spider 24 which is keyed to the crank shaft 7 is provided with three broad finger members 35 having edges 37 and38 that are spaced apart sufficiently to locate the edges of two of the fingers in close proximity to the outer sides of the in'turned ends 121 and 22 and, preferably, to-cover substantially the .the ,{fingers extend into the depressed portion'34 ofthepla'tei3l to locate the upper end well above theinturned end21 of the spring and thus insure the engagement of one or the other ends '21 -or .22 of the spring when the crank shaft 7 is rotated. If desired, the lower ends of the fingers 35 maybe provided with substantially semi-circular notches 3.9 for receiving the inturned end 22 of the spring to further-insure a positive engagement of the inturned end 22 by the finger35 located in juxtaposed relation thereto.
The spider 25 is provided with the fingers 42 and 43 that extend above and below the body of thespider 25. The spider 25 is keyed to the pinion 15 and the crank shaft 7 is provided with a shoulder 44 which locates the body of the spider ata point midway -between the ends of the spring '20. The lingers .42 and 43 are arranged in pairs. The fingers of each pair are located contiguous to each other and the ends of the ifingers of each pair are located so as 'topextend one into the .de-
pressedportion 30 of the shell 8 and the other into the depressed portion 3a of the disc or plate .31, to insure apositive' engagement with one or the other of the inturned ends 21 :and 22. The total width of-the fingers 42 and 43 [of each pair, in the form of construction shown, is less than thedistancebetween the opposing edges .and'38 of .two of the fingers of the spider24 so that any one of the pair of fingers '42 and L43 maybe located between the inturned ends 21 and 22 of the spring and the opposing edges 37 andlBS of two of the fingers of the spider 24. The inturned ends 21 and 22, however, may be .so disposed relative to each other that they may be I located at points to be engaged by edges 37 and 38 more remote as measured in degrees to the axis of the shaft than that shown in the figure, that is, the inturned end 21 may be engaged by any of the edges 37 and the inturned end 22 may be engaged by any one of the edges 38 and likewise the inturned end 21 may be engaged by any one of the fingers 43. The same is true with reference to any one of the fingers 42 and the inturned end of the spring 22.
The disc or plate 31 is secured in position to allow sufficient clearance for the fingers of the spiders 24 and 25 to hold the spring 20 in position by the raised portion 33 that extends along the periphery of the disc, by means of the fingers 50 that are struck up from the plate 1. The fingers 50 are disposed in spaced relation so as to engage the disc on the side thereof opposite to that of the raised portion 32. The ends of the fingers 50 extend into the channel formed by the raised portion 32. Y
The shell 8 is provided with a pair of openings or slots 53 formed in its edge and having a length or width suflicient to receive the sector strip 16 that meshes with the pinion 15 for the purpose of oscillating the arm 17 to raise and lower the windows by the rotation of the crank shaft 7 operating through the spider 24, the inturned ends 21 and 22 of the spring 20, the spider 25 and the pinion 15,
p which is attached to the spider 25.
- The lower end of the plate 1 is provided with a stud 55 that is secured to the plate 1. The stud 55 has a channel 56 that extends substantially diametrically through the end of the stud anda convolute spring 57 is provided with turned end portions 58 and 59, the inner end 58 is located in the channel 56. The inturned end 58 of the spring 57 may protrude into either end of the channel 56, depending on whether the arm 17 extends to the right or to the left side of the plate 1, that is, the construction may be made right or left handed. A finger 60 is struck up from the arm 17 and in position to be engaged by the return end 59, the spring 57 is subjected to the desired tension or distortion by movement of the returned end 59 and hooking the returned end 59 on to the finger 60. The spring 57 thus operates to counterbalance the weight, or material part of the weight, of the Window which reduces the pressure on the crank shaft 7 that may be required to raise the window and operates to increase the pressure that would be required to lower the window if the counter-balancing spring were not used, whereby substantially the same force is required to raise and to lower the window and makes the feel of the crank shaft the same whether the window is raised or lowered.
