ILEVER I SUPPORT Filed May 30, 1930 Patented June 20, 1933 UNITED: STATES PATENT OFFICE BRYAN E. HOUSE, OF SOUTH BEND, INDIANA, ASSIGNOR TO BENDIX AVIATION CORPO- RATION, OF SOUTH BEND, INDIANA, A CORPORATION OF DELAWARE LEVER surroa'r Application flledliay 80,

This invention relates to hand levers and more particularly to the class of hand lever used in connection with brake operating mechanism.

An object of the invention is to provide an anti-rattling hand lever.

Another object of the invention is to provide a lever mechanism having a minimum number of parts.

A further object of the invention is the provision of a confining or tension member for holding the lever against relative displacement when the lever is in the applied or offposition.

And, a further object of the Invention is the provision of a hand lever mechanism which is simple and inexpensive in structure, highly efiicient in use and positive 1n action.

A feature of the invention is a hand lever mechanism comprising a lever fulcrumed on a support and having an arm of cruc form cross-section positioned between a pa1r of stampings deformed to constitute registering undulations to engage and confine the lever against displacement.

The above and other objects of the invention, including various novel combinations of parts and desirable structures will be apparent from the following description of one illustrative embodiment shown in the accompanying drawing, in which:

Figure 1 shows the invention in side elevation- Figure 2 is a section taken substantially on line 22 of Figure 1.

Referring to the drawing, the character 10 represents a suitable body or rigid support to which is fulcrumed at -12 a lever bar 14 having an extended operating arm 16 with extending bosses 18, which in cross-section resembles a cruciform, and having at the extremity thereof, a suitable pivotal connection 20 for a link or pull rod 22.

The lever arm 16 is positioned between a pair of spaced members 24 and 26, preferably arcuate, and deformed into a series of registering undulations 2828 and 30-30 for engaging the cruciformed section of the I lever arm and secured in spaced relation and 1980. Serial No. 457,577.

to the body support as by stud bolts 34, and spacer 36.

Not only does the structure emphasize a novel arrangement of a lever mechanism but also clearly describes a feature which practically prohibits the rattling nuisance evident in the conventional hand lever mechanism.

In operation, as the radial movement of the lever subtends a greater arc, the resist ance of the spaced corrugated members to spread apart is greater and thus effectually holds the lever in the applied position when full engagement of the brakes is required.

The relative position of the cruciform of the lever and the retaining members associated therewith to the fulcrum of the lever, facilitates with comparative ease manual engagement and disengagement of the lever, and, conversely, effectually lessens the possibility of disengagement caused by the tendency of the tensioned pull rods to free themselves into an off-position when the lever is in the applied position.

Although this invention has been described in connection with certain specific embodiments, the principles involved are susceptible of numerous other applications that will readily occur to persons skilled in the art. The invention is, therefore, to be limited only as indicated by the scope of the appended claims.

I claim:

1. An operating mechanism comprising a lever of cruciform cross-section and a retaining means associated therewith having two resilient corrugated members positioned in spaced relation and engaging the lever.

2. An operating mechanism comprising a fulcrumed lever having an arm of cruciform cross-section and parallelly spaced resilient corrugated arcuate confining members embracing the cruciform section.

3. An operating mechanism comprising a lever having oppositely arranged bosses and retaining means for the lever including spaced flexible corrugated members embracing the bosses.

4. An operating mechanism comprising a lever, and means comprising a guide fixed at both ends for yieldingly retaining the lever in a plurality of positions so that the resistance to movement of the lever increases correspondin ly to increases in the angle through whic the lever moves from the vcent-ral position.

In testimony whereof, I have hereunto signed my name.

13. E. HOUSE.
