Bec. 24, 1929 PATENT OFFCE RAYMOND J'. HANSEN, OF REDONDO BEACH, CALIFORNIA WINDOW-RAISING MECHANISM Application filed March 24, 1928. Serial No. 264,315,

My invention relates to window-operating devices, and more particularly to a novel operating mechanism for automobile windows.

The common method ot raising and lowerin@` a glass window in an enclosed automoc a bile comprises a crank which operates through a reducing gear or worm to lower or raise the window, the direction ot rotation ot the crank determining the direction ot travel ot the window. Such a crank is ordinarily unavoidably located in such a position that it is impossible for the person seated next to the window to raise or lower the glass without turning in the seat in order to get a better grip, and secure sufficient leverage, to operate the crank. Besides being inconvenient to operate, such a crank often catches in the clothing when a person is leaving or entering the vehicle. My window-raising mechanism provides a handle which is conveniently located adjacent the glass and in a position in front of the operator. In raising or lowering the window, the operator moves the handle toward or away from him, this pumping` act-ion moving the glass window through a predetermined cycle of opening and closing operations.

It is an object of my invention to provide a window-raising mechanism operable by moving a handle with a pumping motion, this movement being transmitted to a window.

In accomplishing these results, I provide a ratchet gear which is connected to the window through a suitable crank mechanism, this ratchet gear being, in turn, rotated by any reciprocation ot the handle in a manner to move the window through a predetermined cycle.

It is an object ot my invention to provide a window-raising ,mechanism which is actuated by the reciprocation of a lever to draw the window through a predetermined cycle.

It is another object of my invention to provide a window-operating mechanism having a reciprocable handle, the work done on one stroke of this Vhandle being greater than the work done on the other stroke.

Still a tui-ther object of my invention is to provide a device .tor resiliently holding the window in an extreme open and closed position.

Other objects of my invention lie in the provision of a novel operating mechanism tor transferring reciprocating motion into circular motion.

Further objects and advantages of my invention will be made evident hereinafter.

In the drawing, I have illustrated my invention as applicable to an automobile door without limitinpv myself thereto.

Referring to the drawing,-

Fig. 1 is a view illustrating a portion of an automobile body equipped with my invention.

Fig. 2 is a view showing the details ot my invention.

Fig. 3 is a cross-sectional view taken on the line 34-3 ot Fig. 2.

Referring particularly to Fig. l, I illus- 70 trate an automobile body 1() having a door 11 therein, this door operating on hinges 12. rIhis door has an opening 18 which may be entirely closed by a glass 14, this glass being adapted to be lowered in the door 11 into a position indicated by the numeral 15 of Fio. 1 at the will of the operator.

The mechanism for accomplishing this raising and lowering of the glass 14 is best illustrated in Figs. 2 and 3.

Referring to these figures, I illustrate the door 11 as comprisng au outer plate 17, torming the outer surface of the door, and an inner plate 18, these plates being closed at their upper ends by a plate 19. Secured in the door 11 is a suitable supporting structure 2O which may conveniently be the structure bracing the door 11. I have shown this structure as comprising an end sill 21 having a side member 22. Secured to the inner edge ot this side member as by screws 23 is a supporting plate 24 to which a pivot member 25 is attached by bolts 26. This pivot member has a bearing member 27 which journals a shaft 28. To the outer end of this shaft is connected an arm 30. 95 On the outer end of this arm is pivoted a roller 31 which fits into a horizontal channel 32 of a glass-attaching member 33. rl`he glass 14e is secured to the upper end of this glass-attaching member by any suitable means, 1G@

this means being illustrated as a dovetail in the member 33, this dovetail securely holding the lower end of the glass 14. rlhus by raising' and lowering the arm 30, the glass 14 may be raised and lowered in guides 36 provided by the door 11. The horizontal channel 32 of the glass-attaching member 33 is suitably elongated so as to permit this vertical movement of the glass while the roller 31 is moving through an arcuate path. When the glass 14 is in an upper or closed position, the arm 30 assumes a position-indicated by dotted lines 37 of Fig. 2.

A suitable crank mecnanism is provided to thus oscillate the arm in order to move the glass 14 from open to closed posit-ion and vice versa. This mechanism comprises a link 40 pivoted to the arm 30, as indicated by the numeral 41, the upper end of this link being pivoted on a pin 43 attached to a ratchet gear 45 which is, in turn, journalled on a shaft 46, this shaft being' secured to an element 47 which is bolted to the supporting structure. The distance between the pin 43 and the shaft 46 is so proportioned that one complete revolution of the ratchet gear 45 will move the glass 14 through a complete raising and lowering operation. In other words, when the ratchet gear 45 is rotated, the glass 14 moves through a complete cycle each time the ratchet gear has made one complete revolution.

The ratchet gear 45 has teeth 50 thereon. these teeth being pointed at their extremities, as indicated in Fig. 2. Adapted to rotate the ratchet gear 45 in a direction indicated by the arrow 51, is a pair of advancing members which, for convenience, I have termed primary and secondary advancing

members

53 and 54, respectively. These advancing members are operated by a handle 55 extending through an opening 56 in the upper plate 19 so as to be moved by the operator. As best shown in Fig. 2, the primary and

secondary advancingmembers

53 and 54 are respectively pivoted on

pins

53 and 59 carried by the handle 55. The handle 55 is, in turn, pivoted to the element 47 by means of a trunnion 60. The primary and secondary advancing members have engagers 61 and 62 formed thereon, these engagers being of a shape indicated in Fi 2. A spring 63 operates between the advancing

members

53 and 54 to maintain the engager-s 61 and 62 in contact with the` teeth 50 of the ratchet gear 45.

The primary and secondary advancing

members

53 and 54 are effective in rotating the ratchet gear 45. Thus, when the mechanism is in its full line position indicated in F ig. 2, and the operator moves the handle in a direction indicated by the arrow 69, the secondary advancing member 54 moves leftward, the engager 62 thereof meshing with the teeth 50 to turn the ratchet gear in a direction indicated by the arrow 51. IVhen the handle 55 has been moved into an eXtreme forward position, indicated by the numeral 70, the secondary advancing member will have assumed a position indicated by the numeral 71. During this forward movement of the handle 55, the primary advancing member 53 has skipped over a plurality of teeth and now lies in a position indicated by the numeral 73. IV hen the operator again draws the handle 55 rearward, in a direction indicated by the numeral 75, the engager 61 of the primary advancing member engages the teeth of the ratchet gear and moves this gear in a direction indicated by the arrow 51. During this rearward movement of the handle 55, the secondary advancing member skips over a plurality of teeth into its full line position shown in Fig. 2. Thus, the oscillations of the handle 55 are transmitted into a Vrotary motion of the ratchet gear 45, this gear forming a portion of the crank mechanism which moves the glass 14 through its continuous cycle.

In order to counter-balance the weight of the glass 14, I provide a tension spring 80, one end of which is secured to the sill 21 and the other end of which is secured to the arm 30. Thus, the only force required to raise and lower the window is that due to the friction of the glass in the guides 36. It should thus be apparent that the energy required to oscillate the handle 55 is very small. Inasmuch as the -handle 55 is positioned in the forward end of the door 11, it is at all times within convenient reach of the operator, and the pumping action required when moving the handle 55 is almost directly toward and away from the operator.

An operator may invariably exert more force in pulling the handle 55 toward him, in a direction indicated by the arrow 75, than he does in pushing the handle 55 away from him, in a direction indicated by the arrow 69. Due to this fact, the greater amount of work performed in raising orlowering the window should come on the rearward stroke; in other words, when thehandle 55 is being moved in the direction of the arrow 75. This I accomplish by forming the pin 58 on the handle 55 a greater distance from the trunnion 60 than is the pin 59. Thus, fora given angular movementof the handle 55, the pin 58 will travel a correspondingly greater distance than the pin 59, and the engager 61 will thus turn the ratchet gear 45 a greater angular distance than will the engager 62. The leverage obtained by the action of the primary advancing member is thus. different from that obtained bythe secondary advancing member, the greater amount of work being done when the handle 55 is moved in the direction of the arrow 75.

In order to resiliently hold the glass 14 in an extreme upper or lower position, I provide a lug 81 slidable in a member 82 of the element 47, this lug being pointed and springactuated to urge it in a direction toward the ratchet gear 45. This ratchet gear is provided with diagonally opposite depressions 84 in which the lug Si is pressed when either of the openings Se is aligned therewith. The openings Se are so positioned that one of these openings will be engaged by the lug when the glass lli is in an uppermost position and the other will be engaged when the glass is in a lowermost position. rlfhe point of the lug 8l is so designed that it will resiliently hold the glass lll in an extreme upper 0r lower position, but the ratchet gear a5 may be easily turned to release the lug 8l trom the opening 84C in which it is seated. This releasing action is further aided by the peculiar linkage of the ratchet gear 45 and the link 40, this linkage moving the glass le at an increasingly slower rate as this glass nears its upper or lower position. This slower movement as the glass nears its extreme positions also aids in permitting an easy engagement ot the lug and the openings 84, and the increased leverage obtainable in these positions makes the Withdrawal of the lug from the openings an easy matter.
