EUGENE PEARL, 0E PAssAIo. NEW JERSEY VEHICLE.

SPECIFICATION forming part of Letters Patent No. 782,520, dated February 14, 1905.

' Application filed May 16, 1904. Serial No. 208,305.

To all whom, it may concern:

Be it known that I, EUGENE PEARL, a citizen of the United States of America, residing at Passaic, New Jersey, have invented certain new and useful-Improvements in Vehicles, of which the following is a specification.

My invention relates in' general to vehicles, and is particularly adapted for use in connection with the class known'as motor-vehicles.

Ordinarily great diificulty and inconvenience is encountered in gaining access to the mechanism of motor-vehicles, particularly in instances where abreak-down occurs while on the road and immediate repair is required in order that the machine may continue in operation. This results largely from the design of the vehicle. which is built low, without sufficient clearance between the bottom thereof and the ground to provide working space, and access to the mechanism of which from the above is impossible, owing to the use of a heavy cumbersome body inclosing the working parts. In some types of vehicles portions of the body are removable to expose and give access to the mechanism for purposes of examination, repair, &c., and while such provision would serve wherea skilled machinist is available and only trifling repair is required it proves insufiicient for the ordinary operator possessing but little knowledge of machinery and who is unable, therefore, to locate and determine the trouble at a glance.

In order to overcome the difficulty above referred to and facilitate examination, repair, &c., of any part or portion of the mechanism of a motor-vehicle, I propose to raise or tilt the vehicle-body clear of the frame and running-gear, either by powerc'. c. through the medium of the vehiclemotoror by hand-operated devices.

The object of the present invention is therefore the provision of means, in connection with a motor-vehicle, for adjusting the body relatively to the frame and running-gear thereof for the purpose of exposing any part or portion of the mechanism, and thereby rendering the same readily and conveniently accessible for examination, repair, &c.

Mechanism suitable for carrying my invention into effect is illustrated in the accompanying drawings; but I do not wish to be un-.

vehicle, showing the entire body elevated v above the frame thereof. Fig. 4 is a similar view showing the body tilted. Fig. 5 is a detail view of one of a series of jack-screws employed for raising the vehicle-body from the frame, showing also the operating-gear and clutch mechanism. Fig. 6 illustrates a modified form of lifting mechanism, and Fig. 7 is a similar view showing the same adjusted to raise the vehicle-body.

Referring now to the drawings, 1 represents the frame of a motor-vehicle, upon which the motor 2, running-gear, (not shown,) and body 3 are ordinarily mounted. Between the frame and bodythere is arranged mechanism suitable for elevating the body above and clear of the frame. This mechanism may be such as to raise the entire body or either side or end thereof, and it may be operated by power by means of the motor or by hand, as

vertical shaft 6, rotatably mounted in a sleeve 7, which is in turn rotatably mounted in the frame of the vehicle. The screw-shafts are formed in two parts 6 6 connected by a universal or other suitable joint 6. tion 6 of the shaft above the universal joint is threaded for engagement with lugs or pro- That por- TOO , jacks on that particular side or end would be thrown in.

Any suitable gearing, such as that shown at 12, may be employed as a driving connection between the vehicle-motor and the chain when the jacks are to be operated by power, a clutch 13 being provided for throwing the motor in or out, as required.

In order that the jacks may be operated by hand, if desired, they are each provided with a ratchet-wheel 14 in part with the sprocketsleeve, and cooperating therewith is a pawl 15, carried by a lever 16, by which it is given motion to efiect rotation of the screw-shaft through the ratchet and clutch above described.

It may be desirable in some instances to provide only for raising one side or end of the vehicle-body, as shown, for example, in Fig. 4, and in such cases an ordinary pivotal connection might be substituted for the universal joint shown uniting the members or sections of the screw-shafts. Two 'chains might also be employed instead of one shown and arranged to connect the jacks in pairs, thereby dispensing with the individual clutches by which the jacks are thrown in or out of gear with the chain, as above described.

Figs. 6 and 7 illustrate the substitution of toggle-levers 17 17 for the screw-jacks, such levers being pivotally united at 18 and connected, respectively, with the vehicle frame and body thereof, as indicated at 19 and. 20. The adjustment of these levers is effected by means of chains 21 21, winding upon a drum 22, which latteris operated bya crank 23 and secured by a pawl and ratchet 24. The construction of -these levers may be such as to limit their movement relatively to each other, stops 25 being provided for this purpose.

The operation, ad vantages, &c., of the mechanism will be obvious from the foregoing description.

Having therefore described my invention, what I claim as new is- 1. In avehicle, the combination of the frame and body thereof, extensible connections between the body and frame for adjusting one relatively to the other, an individual controlling device for each connection, and operating means common to the several connections.

2. In a vehicle, the combination of the frame and body thereof, extensible connections between the frame and body for adjusting one relatively to the other, operating means common to the several connections, means for throwing one or more of said connections in or out of gear with the operating means, a motor, and'requisite gearing connecting said motor and operating means.

3. In a vehicle, the combinationof the frame and body thereof, screw-jacks connecting the frame and body, operating means common to the several jacks, and individual clutches for throwing said jacks in or out of gear with the operating means.

4. In a vehicle, the combination of the frame and body thereof, screw jacks operatively mounted between the frame and body and provided with universal connections, operating means common to the several jacks, and individual clutches for throwing said jacks in or out of gear with the operating means.

In testimony whereof I afiix my signature in the presence of two witnesses.

EUGENE PEARL.
