Abstract
Abstract A tilt mounting for supporting equipment such as photographic or television cameras, radar antennas, laser beam devices, spot lights, or the like equipment which must be supported in a position to permit selective tilting in a vertical plane. The mounting comprises a tilt table to which the equipment may be secured, with the table having downwardly extending legs, straddled by the upwardly extending arms of a base frame. A pivot-slide connection is formed between the base frame arms and the tilt table legs, permitting the tilt table to be pivoted and slid upwardly with respect to the base frame. A cam and cam follower between the base frame arms and tilt table legs act to urge the tilt table and any equipment supported thereon upwardly as the equipment is tilted, to maintain the center of gravity of any equipment on the tilt table in a relatively horizontal plane. Locking means are provided to selectively fix the tilt table in a selected position.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
169 words
A tilt mounting for supporting equipment for selective tilting of the equipment, said mounting comprising: a base frame having at least one upstanding arm, a tilt table having at least one depending leg, a downwardly facing arcuate cam surface carried by said tilt table leg, a cam follower carried by said base frame arm and having a fixed axis with respect to said arm, said follower engaging said cam surface, a slideway in said tilt table leg, and a pivot journal, carried by said base frame arm, slidably arranged within said slot, said pivot journal being formed with a threaded stud extending therethrough, a manually rotatable knob secured to an outer end of said stud, a brake plate threaded on the free end of said stud, a clutch washer on said stud between said brake plate and the tilt table leg adjacent thereto, whereby upon turning said knob to thread said screw into said journal, said washer will frictionally engage said leg to prevent pivoting of said tilt table.
Claim 2
Dependent Claim
169 words
A tilt mounting for supporting equipment for selective tilting of the equipment, said mounting comprising: a base frame having at least one upstanding arm, a tilt table having at least one depending leg, a downwardly facing arcuate cam surface carried by said tilt table leg, a cam follower carried by said base frame arm and having a fixed axis with respect to said arm, said follower engaging said cam surface, a slideway in said tilt table leg, and a pivot journal, carried by said base frame arm, slidably arranged within said slot, said pivot journal being formed with a threaded stud extending therethrough, a manually rotatable knob secured to an outer end of said stud, a brake plate threaded on the free end of said stud, a clutch washer on said stud between said brake plate and the tilt table leg adjacent thereto, whereby upon turning said knob to thread said screw into said journal, said washer will frictionally engage said leg to prevent pivoting of said tilt table.
Claim 3
Dependent Claim
52 words
A tilt table mounting as in claim 1 including two spaced arms rigidly secured to said base frame and two spaced legs rigidly secured to said tilt table, each of said base frame arms being formed with a slideway, and each of said tilt table legs being formed with a pivot journal.
Claim 4
Dependent Claim
33 words
A tilt table mounting as in claim 1 in which said cam follower comprises a cam surface of a radius less than the radius of curvature of the circular segment forming said cam.
Claim 5
Dependent Claim
43 words
A tilt table mounting as in claim 1 in which said slideway has arcuate ends; and said pivot journal is of a circular cross-section having a radius of curvature slightly less than the radius of curvature of the arcuate ends of said slideway.
Claim 6
Dependent Claim
27 words
A tilt mounting as in claim 1 in which a clutch washer is arranged on said stud between said knob and the base frame arm adjacent thereto.
Claim 7
Dependent Claim
