HARRY LENO, OF SANTA BARBARA, CALIFORNIA.
CAR-LIFTING DEVICE.
Application filed January 18, 1921.
To all whom it may concern:
Be it known that I, HARRY harm, a citizen of the United States, residing at Santa Barbara, in the county of Santa Barbara and State of California, have invented new and useful Improvements in Gar-Lifting Devices, of which the following is a specification.
It is the object of this invention to provide a lifting device for motor vehicles and the like, which is an inprovement upon the apparatus described and claimed in my co-pending application for car lifting device Serial No. 399,835, filed July 29, 1920. The present invention contemplates the provision of improved operating means whereby the respective ends of a vehicle may be independently lifted.
The invention also provides means whereby the lifting mechanism when engaging the automobile frame for lifting the same, will also positively engage the spring supported axles of the vehicle so as to lift the latter with the vehicle and without undue strain upon said springs.
It is a still further object of the invention to provide a construction wherein the elements engaging the ground whenlifting a vehicle, are provided with rollers adapted to rest upon the ground so that the elevated vehicle may be moved laterally, said rollers being swung out of the way when the device is not in use. ,The improved construction also {prdvides means for locking said rollers in operative ground engaging position.
The invention will be readily understood from the following description of the accompanying drawings, in which:
Figure 1 is a plan view of a motor vehicle frame provided with the improved lifting-Fmeans.
ig. 2 is a longitudinal section on the line 2-2 of Fig. 1.
Fig. 3 is an end elevation of the vehicle showing the lifting means in operative position.
Fig. 4 is a detail vertical section through one of the lifting devices.
Fig. 5 is a detail horizontal section through the same.
Fig. 6 is a vertical section through the actuating mechanism for the lifting means.
Fig. 7 is a horizontal section on the line 7-7 of Fig. 6.
Specification of Letters Patent.
Patented Mar. 14, 1922.
Serial No. 438,179.
The improved lifting mechanism is substantially similar in its main features to that previously described in my above mentioned co-pending application, and is instanced as employed in connection with an automobile having frame side bars 1, and front and rear axles 2 and 3, carried by springs 4 and 5.
The improved lifting mechanism consists of a jack mounted upon the automobile frame beyond front axle 2, and a similar jack mounted upon the frame beyond the rear axle 3. Each of these jacks consists of a box-like casing 6 extending transversely of the automobile frame and, preferably, supported below the side bars 1 by means of the depending brackets 7. Bearing lugs 8 project upwardly from casing 6 ad acent the respective ends thereof, and pinions 9 are journaled Within casing 6 by means of axle bearings 10 projecting beyond one of the faces of said pinions and journaled in the bearing lugs 8. Screw threaded elevating rods 11 are threaded through the pinion 9 so as to project above and below pinions 9 and the casing 6.
The pinions 9 are rotated by main shafts 12 and 12 extending lengthwise of the automobile frame and journaled in the respective casings 6. The ends of these shafts within the respective casings are provided with worm wheels 13 meshlng with one of the pinions 9 in each of the casings 6. B this arrangement it will be seen that the reverse rotation of said main shafts will reversely rotate the pinions engaged thereby. Countershafts 14 extend lengthwise of casings 6 and are provided with worm Wheels 15 meshing with the second of the pinions 9 within said casings. These countershafts are rotated by main shafts 12 and 12 as by the bevel gears 16-l7.
An axially shiftable clutch sleeve 23 is keyed upon shafts 12 and.12 within the gear box, and is adapted to engage either a bevel pinion19 journaled upon shaft 12, or a similar beveled pinion l9 journaled upon shaft 12 The bevel pinions 19 and 19 are rotated by a bevel pinion 20, so that by movement of said clutch sleeve either shaft 12 or shaft 12 will be rotated for lifting the respective ends of the automobile. v
The threaded rods 11 are held against rotation relative to the reversely rotatable pinions 9 so that said reverse rotation of the pinions will raise and lower said rods through the threaded connection provided between the latter and the pinions. The means employed for holding the rods 11 of a casing 6 against rotation may consist of an arm 40 extending from one rod to the other and fixed to said rods by threaded engageends'of the rods for retaining the latter relative to the arm 40.
Ground engaging members are carried by the arm 40 and are arranged to be automatically swung into either operative or inoperative position. The ground engaging members consist of arms 43 pivoted by the pins 44 to the respective ends of arm 40. Eachof these arms terminate beyond the pivot 44 in a curved finger45, and below pivot 44 each of the arms 1s provided with a lug 46. The ground engaging arms are so weighted as to normally depend in upright position from arm 40 with the lugs 46 abutting against the arm 40. In this position, when the elevating rods 11 are lowered relative to the casing 6, the arms 43 will engage the ground so that the casing will be elevated. The casings 6 being fixed relative to the automobile frame beyond the front and rear axles thereof will as a consequence cause the automobile frame to be lifted. from the ground.
When main shafts 12 and 12 are rotated in the reverse direction for. again elevating rods 11 relative to casing 6 and thus returning the automobile to the ground, the arms 43 thus lifted with the elevating rods will have their fingers 45 engaged by casings 6 so that the arms 43 will be swung upwardly into substantially horizontal position as shown in dotted lines in Fig. 4. The arms 43 will thus be out of the Way when the lifting mechanism is not in use.
The arms 43 at each end of the automobile are connected by cross plates 50, and bearing brackets 51 depending from the same with rollers 52 journaled therein. These rollers are adapted to engage the ground when the lifting mechanism is in operative position, so that after the automobile has been lifted, it may be moved laterally when desired upon said rollers. In order to retain the lifting mechanism in operative position, a rod 55 preferably, extends lengthwise of the vehicle and is received through one of the plates 50 with its threaded end extending through the plate 50 at the opposite end of the vehicle, and engaged by a nut 56, so as to lock the parts in position for use.
The casings 6 are preferably, provided with means for engaging the axles of the vehicle, so that when the latter is lifted, the weight of the axles will not be carried by the springs. For this purpose brackets 57 extend inwardly from the respective casing 6 to positions beneath axles 2 and 3, and cushioning means shown ascoil springs 58 are preferablycarried by the brackets in such position as to engage the axles. By this arrangement it will be seen that the axles will be lifted with the automobile frame when the lifting mechanism is brought into use.
Various changes may be made without departing from the spirit of the invention ments 41. Nuts 42 are threaded upon the-- as claimed.
What is claimed is:
1. A vehicle in combination with lifting devices at the respective ends of said vehicle, each of said lifting devices having an actuating shaft terminating within a central transmission case, bevel pinion gears rotatably mounted upon the ends of said shafts and continually engaging a master bevel gear supported upon a rotatable shaft and having means for rotating said shaft, and a clutch mechanism for enga ing either of said actuating shafts with t eir respective pinions.
2.A vehicle in combination with lifting devices at the respective ends of said vehicle, each of said lifting devices having an actuating shaft terminating within a central transmission case, bevel pinion gears rotatably mounted upon the ends of said shafts and continually engaging a master bevel gear supported upon a rotatable shaft and having means for rotating said shaft, a clutch mechanism for engaging either of said actuating shafts with their respective pinions, and a single means for shifting said clutch.
'3. A vehicle in combination with lifting devices at the respective ends of said vehicle, each of said lifting devices comprising a casing supported by said vehicle, screw threaded jack shafts vertically mounted near the ends of said casing, worm wheels having threaded engagement with said jack shafts, a countershaft suitably journaled in said casing, a worm mounted on one end of the countershaft and engaging one of theworm wheels, a bevel gear mounted on the opposite'end of the countershaft and engaging a second bevel gear mounted on the main shaft, and a worm mounted on the main shaft and engaging the second of said worm wheels.
