To all whom it may concern:

- Be it known that I, CH RLES GARDNER HUToHINsoN, a citizen of the United States,

residing at Philadelphia, in the State of Pennother; and the objects of my improvement.

are to provide a continuously-conveying car lift, to provide anindividual car for each passenger, andto afford facilities for conveying passengers simultaneously by both the as-. Y cending and descending cars.

I attain these objects by mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side elevation as it appears from a vertical section on the line A B, Fig.

2. Fig. 2 is a top view of the lift, the second tire lift.

ing chains and supporting-rails.

floor being broken away so as to show the en- Fig. 3 is a front end elevation, the second floor being in section through the opening for the lift. Fig. 4 is a side view of an individual car-with its supporting and driving mechanism and a sectionalview of the lift structure. Fig; 5 is a back view of an individual car with its driving and 'guid Fig. 6 is a, front view of an individual car; and Fig. 7, a

side view of the motor, driving-gear, and

sprocket-wheels.

Similar figures refer to similar parts throughout the several views.

The main structure of the lift, asillustrated in the drawings, consists of two side structural steel channel-beams 33, formed so as to extendon an incline from floor 1 to floor 2 with horizontal ends parallel to and firmly secured to those fioors and with easy curves at the angles of the incline with the horizontal ends.

A carrying-rail 4 with an intermediate time A her-bed 5 to dea'den vibration is located on top of each channel-beam 3 3, and these rails and timber-beds are made to conform to the ulpper contour of the channel-beams, to which t ey are firmly secured. A guard-rail 6, running parallel with and above the carryingrail, is supported on a series of standards 7,

which are riveted to beams 3 3 and rails 6.

The structures.3 3 terminate on first and second floors at turning-p oints between which are located bed-plates secured'to' the floors and each supporting a vertical shaft 8. On each of these shafts are mounted to rotate horizontally and extend across the space Y from structure to structure two sprocketwheels 9.10, and a driving-gear 11 is also mounted on the second-floor shaft 8 and secured to the said s rocket-wheels thereon.

Each individuaf passenger-car. 12 has a mountingstud or Wheel-axle 14 rigidly secured t0 the back of the car near the top. On

each of these studs 14 are mounted a flanged supporting-Wheel 15, which engages the care rylng-rails 4,.a flanged guide-wheel 16, which engages the guard-rails 6, a chain-link 17 and a collar 18 and pin 19 for retaining the wheels and link in position on the stud.

A'oaster 20, carrying a chain-link 21, is secured by a swivel-joint to the back of each car near the bottom. The caster-wheel engages a guide 22, formed on the channelbeams 3 3, the function of caster and guide being to keep the cars in an u right position.

An endless series of indivi ual cars 12 are connected and moved by an endless drivingchain 23, which is formed of the stud-links 17 and connecting-links 24, and the cars are guided and kept in position by an endless guide-chain 25, which is formed of casterlinks 21 and connecting-links 26.

-The cars are operated by a motor 27, mounted on the second floor and provided with a pinion 28, which'engages gear 11 to actuate the lift. A cover 29, secured to the structure, runs entirely around the lift and protects the mechanism. An open space is left -on the incline between the structures 3 3; but

partitions

30 and 31 on floors 1 and 2 isolate the mechanism located at those points.

Inclined floors 32 32, attached to structures 3 3, are laid outside the structures, and these inclined floors are each provided on their outer sides with a newel-post 33 anda partition and hand-rail 34, which partitions and hand-rails extend around the lift-opening on'floor 2.

Each individual car consists of a floor 35, a

back 36, and sides 37 38, and each car is provided on its forward side 37 with a handgrasp 40, which the passenger grasps when boarding and occupying a car.

The endless series of individual passengercars 12 are attached in close proximity to each other to the endless driving-chain 23, and both the cars and chain are suspended by studs 14 and wheels 15, so as to travel the rails 4 and then be carried around the ends of the lift by the engagement of the teeth of the sprocket-wheels 9 with the links 24 of the driving-chain 23. In like manner the teeth of the sprocket-wheels 10 engage links 26 of endless guide-chain 25. As the

chains

23 and 25 pass around their sprocket-wheels the studs 14, with their mountings, and the easters 20, with their mountings, each occupy the spaces between the sets of teeth-on the sprocket-wheels. The function of the flanged wheels 16 is to retain the moving parts in position by the engagement of those wheels with the guard-rails 6.

The guide-chain 25 is not intended to be a driver, although it may assist; but its function is to guide and keep the cars 12 in an upright position at all times, so that as passengers enter, occupy, or leave the cars those cars cannot be thrown out of their upright position. Thesprocket-wheels located at the turn on floor 1 are like the driving sprocket-wheels at the turn on floor 2 but their function is only to support and guide the cars around that end of the lift.

In operation the endless series of individual passenger-cars 12 travel continuously in the direction indicated by the arrow in Fig. 2. The bottoms of the ears travel in close proximity to the landings or floors 1 2, so that a passenger may easily enter or leave a car at those landings. The inclined floors, with their newelposts, hand-rails, and partitions, are designed to be used only as a protection to the lift and passengers.

To ascend by the lift, a passenger enters a car from the first-floor landing by grasping the hand-grasp 40 of a passing car, and stepping onto floor 35 of the car he is now protected and may be comfortably supported by the hand-grasp and three sides of the car, and when the car reaches floor 2 he simply relinquishes the hand-grasp and steps from the car to that landing.

To descend by the lift, a passenger enters a passing car from the second-floor landing, as in the ascent, and leaves the car on the lower landing.

Moving at a moderate speed, with the cars all occupied, the lift is capable of handling several thousand passengers per hour each way.

While I have only illustrated and described my lift as extending between two landings, it may extend to three or more landings, as it may extend along floor 2 and then up an incline to a third floor, or it may ascend an incline at one point, proceed along a level, and descend at another point.
