Specification of Letters Patent.

Patented Mar. 2,1915.

Application filed August 8, 19-13. Serial No. 183,715.

To all whom it may concern:

Be it known that l, Gorrrnmnldnnnnann Moi: on, a citizen of the German Empire, residing at"Leipzig, in Germany, have invented certain new and useful Improvements in Balancing Mechanism for Vehiclel Vindows, of which the following is a speci fication.

This invention relates to window balancing mechanism of the type wherein a lever system of the type known as lazy tongs is used in combination with springs attached thereto and tending to hold said lazy tongs in extended position. Used in connection with the windows of vehicles, having hollow doors into which the windows slide when opened, mechanism of this type is subjected to a great deal of vibration an has been found to create a very disturbing noise.

The object of my invention is to provide an arrangement whereby this noise is avoided or largely reduced.

The invention is illustrated in the accompanying drawing, in which- Figure 1 is a front elevation of the mechanism, partly in section, Fig. 2 a side view thereof, also partly in section, and Fig. 3 a vertical cross-section of the door, with the window therein.

In the drawing, a designates the window, and a the door, I) being the lazy tongs. The latter are connected at the upper end to the window a by means of a pivot cl, the axis of which lies in the plane of the window, so that the lazy tongs can assume varying angles to the said plane. At the lower end the lazy tongs system is pivoted to the door a by means 0 a hollow tubular pivot or shaft h, to which it is attached by means of a fastening g. The two bottom levers of the lazy tongs are pivoted to this fastening at 0, 0, their fulcra being spaced apart, and these levers have arms I) extending through a slot at in the upper part of the tubular shaft. The latter contains two coiled springs f engaged with the arms 6 and with hooks m which are adjustably fixed to the heads h of the shaft by means of nuts. The shaft is mounted in bearings a, which lie within the hollow door and form part of same, the arrangement of the bearings being such that the lazy tongs can assume varying angles to the plane of the cor.

The tubular shaft it may be used as a fact that'the pivots o o lubricant container filled with grease, thick other lubricant, as it has no'outlet the slot n in its upper part. The fthe'bottom levers are spaced apart enables these levers to he placed in one plane, so that only a narrow slot n is required.

What I claim as my invention and desire to secure by Letters Patent of the United States is 1. The combination, and a Window sliding in said door, of a lazy tongs system, a spring device engaged with said lazy tongs and tending to hold same in its extended position, a pivot connecting said lazy tongs to the door and enabling the lazy tongs system to assume varying angles to the plane of the door, and a pivot connecting the lazy tongs to the window and enabling the lazy tongs system to assume varying angles to the plane of the window.

2. The combination, with a vehicle door, and a window sliding in said door, of a lazy tongs system, a pivot connecting the lazy tongs to the bottom edge of the window, enabling the lazy tongs system to assume varying angles to the plane of the window, a tubular pivot connecting the lazy tongs to the door, enabling the lazy tongs system to assume varying angles to the plane of the door, said tubular pivot having a slot and the lazy tongs having two lever arms extending through said slot into said tubular pivot, and springs attached within said tuhular pivot. engaged with said arms and tending to hold said lazy tongs system in its extended position.

3. The combination, with a vehicle door and a window sliding in said door, of a lazy tongs system, a pivot connecting the lazy tongs to the bottom edge of the window, enabling the lazy tongs system to assume varying angles to the plane of the window, a tubular pivot connecting the lazy tongs to the door, enabling the lazy tongs system to assume varying angles to the plane of the door, said tubular pivot having a slot and the lazy tongs having two lever arms exoil, or except with a vehicle door tending through said slot into said tubular pivot, and springs attached within said tubular pivot, engaged with said arms and tending to hold said lazy tongs system in its extended position, said tubular pivot being adapted to hold a lubricant.

a lazy tongs system, a pivot connectin ing the lazy tongs door, and the lazy arms, with their fulcra spaced apart on and a window sliding in said door,

the lazy tongs t0 the bottom edge of the 7 Window, enablingthe lazy tongs system to assume varying angles to the plane of the Window, a tubular pivot mounted in said' door and having a slot, a fastening connectto said tubular pivot, the latter enabling the lazy tongs system to as sume varying angles to the plane of the tongs having two lever said fastening, extending through said slot g into said tubular pivot, and sprlngs attached arms and tending to 'hold said system in its extended position. i
