Application filed June 26, 1909. Serial No. 504,466.
To all whom it may concern:
Be it known that I, J ESSE W. RENo, acitizen of the United States of America, and
resident of the city, county, and State of New York, have invented certain new and useful Improvements in Inclined Elevators, of which the following is a specification.
I My invention relates to inclined elevators.
The object of my invention is to provide an elevator of this class Which shall be simple'and effective in its construction and operation and in which the individual steps are of a size sufiicient to accommodate a passengers feet and are arranged to travel along a stationary incline andto cooperate at the upper and lower ends of the incline with comb landings whereby the passengers may be conveniently and safely received on and discharged from said steps.
Another object of my invention is to pro-.
vide a simple and eflicient means for operating said elevator.
My invention consists in providing a statlonary inclined support, a series of steps hinged together in the form of an endless belt, in'arranging the tread surfaces of the steps so that when they are in operative position upon the inclined support the surfaces are themselves inclined in the same direction and preferably at about half the angle of the inclination of said support, in providing grooves in the steps arranged in .alinement with each other longitudinally of the direct-ion of said tread belt, in providing comb landings at theupper and lower extremities of the incline, in securing sections of rack to the under side of the steps of which the tread belt is composed, in providing a driving pinion adapted to engage said racks to operate said tread belt, and in other novel features and combinations to be hereinafter more fully pointed out and detread belt is composed of a series of uniform steps 3which are hinged together in the form of an endless belt. Each alternate step-is provided with a section of rack 4:, centrally secured to its under side, and the steps alternating with these are provided with a pair of racks 5. The ends of the double racks 5 overlap the ends of the single racks 4 and these ends are provided with a pin connection 6 by"means of which the steps are pivotally connected to each other. A series of grooves 7 is formed in the tread surface of thesteps in alinement with each other and parallel to the longitudinal direction of the belt and these grooves register with the prongs 8 of the comb landing. Track rails 9 are secured to the supporting structure and the steps are provided with rollers 10 which are adapted to travel upon said track rails. The tread surfaces of the steps 3 are arranged at an angle to the track so that when the steps are in operative position on the incline the tread surfaces are inclined to the horizontal in the same direction as the said incline and preferably at The purpose of this arrangement. is to permit the use of integral steps upon a relatively steep incline without increasing the risers an amount, or to an extent, which would be disadvantageous when used in connection with comb landings. By careful experiments I have ascertained that the tread surface of the steps may be inclined as described without interfering with the safety or convenience of passengers and by keeping the risers down to the llmits made possible by this construction, the operation at the landin sis materially benefited. This is particular y true at the lower landing where passengers are apt frequently, in entering upon the tread belt, to so place their feet that they will rest partly upon one step and partly upon another. Beneath the tread belt and preferably near the upper end of the incline, I provide a pinion 11, mounted on the shaft 12 and adapted to be driven in any convenient manner. This pinion engages the racks secured to the under side of the steps and may be operated to drive the tread belt in either direction.
Having thus described my invention what I claim is:
1. In an inclined elevator the combination with an inclined support, of a tread belt adaptedto travel upon said support, said about half the angle of the said incline.
tread belt being composed of a series of uniform steps havlng working or tread surfaces flat and inclined from the horizontal in th same direction as said support.
2. In an inclined elevator the combination with an inclined support, of a tread belt adapted to travel upon said support, said tread belt-being composed of a series of uniform steps having Working or tread surfaces flat and inclined from the horizontal in the same direction but at an angle less than that of the inclination of said support.
3. In an-inclined elevator the combination with an inclined support, of a. tread belt a 4. In an inclined elevator the combination with an inclined sup ort, of a tread belt composed of steps lin ed together adapted to travel upon said support, a centrally diswith an inclined support, of a tread belt composed of steps llnked together adapted to travel upon said support, a centrally disposed rack, and a pair of racks disposed on either side of the center secured respectively to the under side of alternating steps and a hinge connection between the adjacent ends of the racks on contiguous steps.
6, In an inclined elevator the combination with an inclined support, of a tread belt adapted to travel upon'said support, said beltbeing composed of a series 0 uniform steps havmg their Working or tread surfaces inclined from the horizontal in the same direction as said inclined support and having longitudinal grooves formed therein,
and a comb landingadapted to register with I
