Abstract
Abstract A tiltable cooking pan which is pivotally connected to a support at the front wall section of the pan. A rigid actuator rod has one end pivotally connected to the pan rearwardly and above the pivot connection of the pan to the support. The opposite end of the actuator rod is connected to a slide member which, upon fore and aft shiftable movement relative to the pan and support, causes the pan to be raised and l

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
161 words
A tiltable cooking pan having a side wall with front and side sections, said pan carried upon a support, means pivotally connecting said pan adjacent its front wall section to said support for pivotal movement about a horizontal axis, the improvement comprising a rigid actuator rod having upper and lower ends, means pivotally connecting the upper end of said rod to one pan side wall section above and rearwardly of said pan to support pivot means, the lower end of said rod positioned below and rearwardly of said pan to support pivot means in all operative positions of the pan, actuator means carried by said support and connected to the lower end of said rod for shifting said lower rod end forwardly and rearwardly relative to said pan in a horizontal path to pivotally raise and lower said pan in selected incremental movements about said pan to support pivot means and thereby position said pan at a selected angle of tilt.
Claim 2
Dependent Claim
161 words
A tiltable cooking pan having a side wall with front and side sections, said pan carried upon a support, means pivotally connecting said pan adjacent its front wall section to said support for pivotal movement about a horizontal axis, the improvement comprising a rigid actuator rod having upper and lower ends, means pivotally connecting the upper end of said rod to one pan side wall section above and rearwardly of said pan to support pivot means, the lower end of said rod positioned below and rearwardly of said pan to support pivot means in all operative positions of the pan, actuator means carried by said support and connected to the lower end of said rod for shifting said lower rod end forwardly and rearwardly relative to said pan in a horizontal path to pivotally raise and lower said pan in selected incremental movements about said pan to support pivot means and thereby position said pan at a selected angle of tilt.
Claim 3
Dependent Claim
198 words
A tiltable cooking pan having a side wall with front and side sections, said pan carried upon a support, means pivotally connecting said pan adjacent its front wall section to said support for pivotal movement about a horizontal axis, the improvement comprising a rigid actuator rod having upper and lower ends, means pivotally connecting the upper end of said rod to one pan side wall section above and rearwardly of said pan to support pivot means, the lower end of said rod positioned below and rearwardly of said pan to support pivot means in all operative positions of the pan, actuator means carried by said support and connected to the lower end of said rod for shifting said lower rod end forwardly and rearwardly relative to said pan to pivotally raise and lower said pan about said pan to support pivot means, said actuator means including a rotative member having a substantially horizontal axis of rotation and a shiftable member carried by said rotatable member, means connecting said shiftable member to said rotative member for movement along said horizontal axis upon rotation of said rotative member, and means pivotally connecting said lower rod end to said shiftable member.
Claim 4
Dependent Claim
198 words
A tiltable cooking pan having a side wall with front and side sections, said pan carried upon a support, means pivotally connecting said pan adjacent its front wall section to said support for pivotal movement about a horizontal axis, the improvement comprising a rigid actuator rod having upper and lower ends, means pivotally connecting the upper end of said rod to one pan side wall section above and rearwardly of said pan to support pivot means, the lower end of said rod positioned below and rearwardly of said pan to support pivot means in all operative positions of the pan, actuator means carried by said support and connected to the lower end of said rod for shifting said lower rod end forwardly and rearwardly relative to said pan to pivotally raise and lower said pan about said pan to support pivot means, said actuator means including a rotative member having a substantially horizontal axis of rotation and a shiftable member carried by said rotatable member, means connecting said shiftable member to said rotative member for movement along said horizontal axis upon rotation of said rotative member, and means pivotally connecting said lower rod end to said shiftable member.
Claim 5
Dependent Claim
27 words
The cooking pan of claim 2 wherein said actuator means includes a hand crank means connected to said rotative member for imparting rotation to said rotative member.
Claim 6
Dependent Claim
35 words
The cooking pan of claim 3 including yieldable biasing means connected between said support and at least one of said rod and shiftable member normally urging said lower rod end forwardly relative to said pan.
Claim 7
Dependent Claim
28 words
The cooking pan of claim 2 wherein said actuator means includes a drive motor means operatively connected to said rotative member for imparting rotation to said rotative member.
Claim 8
Dependent Claim
25 words
The cooking pan of claim 2 including means in contact with said support for supporting said shiftable member as it moves along said rotative member.
Claim 9
Dependent Claim
26 words
The cooking pan of claim 6 wherein said shiftable member supporting means includes wheel means carried by said shiftable member in rolling contact with said support.
Claim 10
Dependent Claim
46 words
The cooking pan of claim 2 wherein said pan includes an upper marginal edge portion and said side wall thereof includes a rear section, said pan to support pivot means located at said marginal edge portion between said front and rear wall sections of the pan.
