11 Claimsf l Drawing Figure 1 MULTI-MOVEMENT SINGLE LEVER CONTROL BACKGROUND OF THE INVENTION lever are normally bulky, complex and expensive to manufacture and service.
SUMMARY OF THE INVENTION An object of this invention is to .provide a compact, non-complex and economical single lever control adapted for multi-movements to actuate two or more control valves therewith.
The single lever control comprises a stationary support having a bellcrank pivotally mounted thereon for pivotal movement about a first axis. The bellcrank comprises first and second arms extending therefrom and a handle pivotally mounted on the first arm for pivotal movement about a second axis which is disposed transversely relative to the first axis. A connecting rod is pivotally connected to the handle and extends in the general direction of the first axis for attachment to the control element of a first control valve whereas the second arm is adapted for attachment to the control element of a second control valve. Pivotal movement of the handle about the second axis will function to reciprocate the connecting rod in the direction of the first axis to actuate the first control valve whereas pivotal movement of the handle about the first axis will function to actuate the second control valve.
BRIEF DESCRIPTION OF THE DRAWING Further objects of this invention will become apparent from the following description and accompanying drawing which is an isometric view of a single lever control embodying this invention.
DETAILED DESCRIPTION 'The drawing illustrates a single lever control comprising a stationary support, including spaced support brackets 11, mounted in the operators cab of a wheel loader, for example. A tubular bellcrank 12 is pivotally mounted on the support brackets for oscillatory movement about an axis X. The bellcrank has longitudinally spaced first and second arms 13 and 14, respectively, extending therefrom in at least approximate perpendicular relationship with respect to 'each other.
A handle 15 is pivotally mounted to first arm 13 of the bellcrank by a pin 16 for oscillatory movement about a second axis Y, preferably. disposed perpendicular to first axis X. Arms 13 and 14 extend in the general direction of the first and second axes, respectively. The handle comprises a clevis 17, having its lower bifur cated end pivotally mounted on first arm 13 by pin 16.
An extension 18, secured to the clevis to extend away therefrom in the general direction of first axis X, has a hand lever 19 secured thereon to be selectively moved by an operator. A connecting rod 20 is connected at a universal ball and socket connection 21 to clevis 17 of the control arm and extends through bellcrank 12 in general alignment with axis X. The opposite end of the connecting rod is pivotally connected to a control element 22 of a first control valve 23 by first linkage means 24.
The first linkage means comprises a bellcrank 25 pivotally mounted on the stationary support by a pivot pin 26. The bellcrank comprises a first arm 27 pivotally connected to rod 20 by a pin 28 and a second arm 29 pivotally connectedto a link 30. The link is pivotally interconnected between arm 29 and control element 22 by pins 31 and 32, respectively.
Second linkage means 34 pivotally interconnects sec- 'ond arm 14 and a control element 35 of a second control valve 36. The second linkage means comprises a universal ball and socket connection 37 connecting arm 14 to a single link 38. A pivot pin 39, in turn, connects the lower, clevis end of the link to control element 35.
In operation, the operator may pivot control lever 19 in the illustrated A direction to reciprocate connecting rod 20 in the general direction of axis X to actuate con- 7 moved in a compound direction to move both control elements 22 and 35 simultaneously, if so desired. Control elements or stems 22 and 35 may be suitably connected to valve spools or the like which function in a conventional manner to selectively communicate hydraulic fluid through the respective valves.
