GAETANO P. MANSIONE, OF NEW YORK, N. Y.

ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 612,780, dated October 18, 1898.

Application filed F bruary 19, 1898. Serial No. 670,943. (No model.)

To all whom it may concern:

Be itknown that I, GAETANO P. MANSIONE,a citizen of the United States, and a resident of the city and county of New York, in the State of New York, have invented certain new and useful Improvements in Elevators, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

This invention relates to the general class of elevators in which are included machines, appliances, or devices for raising or lowering persons or things.

The primary object of the invention is to provide improved devices for effecting the raising or lowering of the car which shall be more certain in operation and less liable to derangement than devices heretofore employed for the purpose.

A further object is to provide for the extension of the elevator to different heights, as may be required from time to time.

The invention will be more fully described hereinafter with reference to the accompany ing drawings, in which a convenient and practical embodiment of the main features of the invention is illustrated, various details of construction also being represented.

In the drawings, Figure 1 is a view in side elevation of an elevator which embodies the improvements herein referred to, parts being shown in section and other parts being broken away. Fig. 2 is a top plan view of the same with the guides in section. Fig. 3 is a section on the plane indicated by the line 3 3 of Fig. 1.

The operating mechanism of the elevator may be supported in any convenient manner, as by a framework A of ordinary construction, which it is not necessary to describe in detail herein. Supported by the framework or otherwise, if more convenient, are one or more guides B, which direct the elevator-car O in its movements and have also another function, which will be referred to hereinafter. For purposes of an ordinary elevator four such guides are ordinarily provided, as represented in the drawings. These guides may be continuous, and they may be constructed in any desired manner so far as the action of the operating mechanism is concerned; but they are preferably tubular or hollow and slotted along one side, as shown at b in Fig. 1, in which figure the near side of one of the farther guides is exposed to view by breaking away the upper portion of one of the guides nearer the eye and as shown also in Fig. 2. In order that the elevator maybe extensible to suit diflferent heights, each guide is made in sections, as represented in Fig. 1. As there shown, the upper end of each section is provided with an enlargement or socket b, into which the lower end of the section above may be set. Any .suitable means may be employed for bracing the sections and for securing one to another, and in Figs. 1 and 2 are represented devices which enable the necessary bracing to be effected when four guides are employed without 1'e sorting to external means of support. As there shown, a brace or bar D is secured, preferably by a pivot d, to each section near its lower end and engages the adjacent guide near the upper end of the corresponding section, as by means of a pin or stud d, the end of the bar being slotted, as at CF. The bar D may also be provided with a downwardlyextending arm D, which, by means of a pin 01 and slot d engages the section below and in line with that to which the bar is pivoted- In this manner the guides are firmly braced and the sections securely held together, while at the same time the addition or removal of sections, as may be required according to the height to which the elevator is intended to operate, is effected without difficulty.

In place of the ropes or cables commonly employed in elevators heretofore constructed are substituted in this case toothed chains,

there being in the construction represented in the drawings one toothed chain for each corner of the car-platform 0. Each chain E is made up of links 6 e, which are pivoted one to another and are toothed on one or more sides, being shown in the drawings as toothed on two opposite sides. The flexibility of the chain permits it to be coiled upon a suitable drum, and it is the function of the guide B to prevent flexure of the chain between the car and the operating mechanism, each chain in the construction represented in the drawings moving freely within the corresponding tubular or hollow guide B and being connected to the car by a pin or stud c, which travels in the slot 1) of the guide. In this man ner the chain, having no backlash orlost n10- tion between its links, operates as an inflexible rack-bar, but, as above stated, is capable of being coiled upon a drum.

The chains may be operated by any suitable gearing. The system of gearing shown in the drawings comprises acommon drivingshaft F, actuated by any suitable motor, from which motion is transmitted by a pinion f and on the one side by two intermediate gears f and on the other side by a single intermediate gear f to shafts The two shafts of each pair are provided with intermeshing gears f so that they shall rotate together, and at their ends they are provided with pinions the pinions at the corresponding ends of each pair of shafts j" meshing with the teeth on opposite sides of the corresponding chain E. By such means as those just described the several chains E are operated together to raise or lower the car 0 as the case may be.

It is desirable to provide a take-up for each chain as it is released from the guide and the operating mechanism, and a device of this character is shown in the drawings. As there represent-ed, each chain is connected to a drum G, mounted loosely on a shaft g and caused to rotate about said shaft by a coiled spring 9'' in order that it may take up the chain as it is released from the operating mechanism. In order that the line of the chain Within the guide may be always tangential, or substantially so, to the surface of the take-up, notwithstanding the progressive increase of diameter thereof by reason of the winding of the chain upon the drum, the shaft 9 is shifted as the winding progresses. To enable this to be done, the shaft is mounted in arms H, which are secured to a shaft h. An arm h on said shaft h is operatively connected by a link or rod 7L Wltl1 a cam I. The latter is operated in any convenient manner, being represented in the drawings as formed in one case in the face of a gear 6, mounted on a shaft t" and driven by a pinion f on the main driving-shaft F, and as formed in the other casein the face of a disk i which is also mounted on the shaft t".

It will be obvious that the details of construction and arrangement of an apparatus in which the invention is embodied may be varied considerably without departing from the spirit of the invention, and therefore it is to be understood that the invention is not to be limited to the precise construction and arrangement shown and described herein.

I claim as my invention 1. In an elevator, the combination of a car, a toothed chain to which said car is connected, a guide for said chain, operating mechanism engaging said chain independent of said operating means and movable bodily away from the line of said chain, a take-up for said chain, and means to shift the position of said take-up.

2. In an elevator, the combination of a car, a toothed chain to which said car is connected, a guide for said chain, operating mechanism engaging said chain, a take-u p for said chain, a swinging arm upon which said take-up is mounted, and a cam and intermediate connections for shifting said arm.

3. In an elevator, the combination of a car, a toothed chain to which said caris connected, a guide for said chain composed of sections, means to secure one section in place upon another,and operating mechanism engaging said chain.

4. In an elevator, the combination of a car, chains to which said car is connected, guides for said chains, braces extending from one guide to another, and operating means for said chains.

5. In an elevator, the combination of a car, chains to which said car is connected, guides for said chains, braces pivoted upon the several guides and engaging adjacent guides, and operating means for said chains.

6. In an elevator, the combination of a car, chains to which said car is connected, sectional guides for said chains, braces pivoted upon the several sections of the several guides and severally engaging the section below that to which each is pivoted, and the corresponding section of an adjacent guide.

This specification'signed and witnessed this 16th day of February, A. D. 1898.

GAETANO P. MANSIONE.
