7 Claims. 1
My invention relates to an improved mechanism for manually controlling electrically driven apparatus, and also relates to such control mechanism in conjunction with workmans lift apparatus such as disclosed in my copending application Serial No. 71,349, filed January 1'7, 1949, now abandoned.
It is among the objectsof my invention to provide a simple control mechanism for selectively actuating a plurality of switches by a singlebperating lever.
Another object is to provide a mechanism of the character described in which the motions of the operating lever maybe related to the motions of the apparatus being controlled.
A further object is to provide a workmans lift apparatus having a work station mounted for universal movement to any desiredelevated position, and incorporating improved mechanism so that the workman can control his position with- L out leaving the work station.
A still further object is to provide such a control mechanism having an operating lever with universal motions corresponding to the universal motions of thework station of the lift apparatus being controlled.
The invention possesses other objects and fea-- ture of advantage, some of which, with the fore going, will be set forth in the following description of my invention. It is to be understood that I do not limit myself to this disclosure of species of my invention as I may adopt variant embodiments thereof within the scope of the claims.
Referring to the drawings:
Figure l is a side elevational view of lift apthe lever, and means on the lever for selectively actuating one or more of the switches upon tilting of the lever. The operating lever is also pref erably axially extensible with mea'ns provided for actuating additional switches upon axialmovement of the lever; The several switches of the ill 2v mechanism are connected with devices such as motors of the electrically driven apparatus to be controlled. Thus, in a workmans lift apparatus having a work station on the end of an extensible boom rotatably mounted for turning movement about a vertical axis and swinging movement about a horizontal axis, the improved control mechanism is located at the work station and the switches are connected to the boom drive motors so that sidewise tilting motions of the operating lever turn the boom clockwise or counterclockwise, vertical motions of the lever swing the boom up or down, and forward or back tilting motions of the lever extend or retract the paratus are controlled by separate switches at the work station. That arrangement is entirely practical but it is somewhat difficult for a work-' man to learn. to operate the apparatus because the manipulation of the separate switches is not directly related to the motions of the Work station. This problem is overcome with my pres ent improvements.
The lift apparatus comprises a vehicular mount 5 having a bed 2 and wheels 3 and 4. This vehiole may be a trailer having a tongue 6 for distance traveling, although separate means are also preferably provided for driving and steering the mount about a local area; A Work station E is carried on the outer end of a boom 8 which projects from the mount .l, the work station being preferably a cage pivotally suspended from the boom.
Boom 8 is rotatably supported on the mount for turning about a vertical axis, as by a hollow column 9 journalled by rollers ll about a post projecting from the bed of the mount. The boom is turned about the vertical axis by'a reversible motor 12 drivably connected tov column 9 by suitable gearing 13. 30cm 8 may thus be turned either clockwiseor counterclockwise depending upon the direction of rotation of motor The boom is also rotatably supported for swinging' movement about a horizontal axis, as by a pivot pin I4 on the top of column s. A suitable acterdisclosed, means arealso preferably provided for driving and steering the vehicular mount 2, which means is controllable at the elevated work station '5 so that the workman can shift the position of the mount about a local area. A motor driven transmission 61 is arranged to drive the rear wheels, and a motor driven steering mechanism 68 is provided for guiding the front wheels. The control device for the reversible motors of the drive and steering mechanisms is preferably similar to that above described for the boom. For example, the switches 43 and 49 may be employed for driving the vehicle forwardly or in reverse, while the switches 53 and 54 may be employed for turning the vehicle to the right or to the left. In this case the vertical switches would not be required and the control mechanism would therefore be of more simplified construction.
While my control mechanism is particularly well adapted and highly useful in the control of the lift apparatus herein described, it is understood that the improved mechanism may be used for controlling a wide variety of electrically driven apparatus.
