ELEVATOR.

Application filed June 6,

To all whom t may concern: f

Be it known that I, HORACE L. CAMPBELL, a citizen of the United States,- residing at the city of4 St. Louis,`infthe State of Missouri, have invented certain new and usefuLImprovements in Elevators, of which theztol-v lowing is a specification.

This invention is illustratedin the draw-V ings. in the `formA of an elevator, but thel construction is adapted for various useful pur poses, among which may be mentioned, for the purpose of examples but not for the purpose of exhaustive enumeration, bookcases, wardrobes, grocery and other-bins, and receptacles for the storage of stocks of'mervIt chandise for retail `and other stores. may be used, also,` for airplane bodies for the; reception of a load onpassengers.

The main idea ofthey invention is to provide a plurality of receptacles suitably connected to a central shaft or rotating means in such a manner that the said receptacles will be maintained in a fixed relation thereto, Yand by which the contents of the said receptacles will vnot be tilted or tipped or shaken orl dislodgechbut when once placed in' such a receptacle .are maintained in a stable condition on the same level.

ln the caseof elevators, the goods or articlesuare placed in the receptacles for thepurpose of being raised or lowered from onewfloor or level to another. In the case ot' use vot this invention for the' storage of merchandise ory as a bookcase,the object is f to increasethe floor .space by `moving a receptacle, the contents of which is not inim-V mediatek demand, upward and `out A of` the way ywhile somev other receptacle is in immediate use, but with the potentiality that the removed kreceptacle `can be easily returnedv to. a position where.A it ican beI most` easily reached by the` user'.`

This device may beconstructed of any size accordingrto the purpose 'for which it is in- '-1 tended. It'may be comparatively small, or it may be large enough to carry articles from floor to floor in a` tall building.

One use of this device that is especially important `is in handling baggage or express mattei-at a railwayl station,where, ifdesired,`:it. caribe .mounted on-wheels-or rollers and moved! adj acenty to anexpressor and elevate the s-ame to a higher runway,

platform, or floor, where it can be more easily handled than on the walkway used by passengers and others.

ln the-accompanying drawings Jforming part of this'specification, in which like numbers offreference denote like parts wherever 4 they occur,

Figure 1 is an end elevationof an ernbodiment of the invention;

Figure 2 is a side elevation; and v .Figure is a fragmentary enlarged sectional-view taken on the line` 3 3 in Figure 2, lookingyin the direction indicated by thel arrows.`

A suitable frame, preferably of angleirons orA the like, is provided, consistingiof uprights I1, cross-pieces 2, and braces 3. The framework shown in Figure .1 is duplicated at theother side (or end) of the structure, as shown infFigure 2.

Braces 3 are fastened toithe housing 4, and in conjunction withbraces 17 support the same at approximately the center of the framework.- The lower braces 17 are the principal supports `for housing L1, but` are assisted in such support by the lower braces 3. The' upper braces 3 and 17 act as supports andsteadying members for the housing. It is to beunderstood that the braces and 17, as shown in Figurevhare duplicated on. theY opposite side o1 the machine.

A plurality `ot `storage receptacles 6 is provided, the sanie-l being .adjusted to `rotate with the pair of rings 7 that, withinthe above-mentioned frame, form the end mem` bers et the mechanism.V

`Each receptacle 6 bears a ring 8 fastened thereto by screws 9 ory other suitable means.

.Each ring 8 is `formed like an angleiron, so

y17 are attached `at one end by bolts 18 to ring 7, and at the opposite end by bolts 19` togear 22. Bolts 2O fasten the external spur gear. 21 stationary to theframe 3. There is providedxan external spur gear VZland` an internalspur gear- 1522.V Spur gear-22 is so .formed that roller 105 l f 23 tracks "on ,onek face :thereof and roller baggage 'can-and :there receive l such-matter '1 2/1 onfzanotherfface,the11eof.- Itis to bef.v understood that there is a plurality of rollers 23 and a plurality of rollers 24, the same being borne by arms 25 fixed to the side Walls of housing 4 by screws 26.

The entire mechanism .is driven from central shaft 27, which primarily actuates gear 28, which meshes with and drives spur gear 29. lThis meshes with internal spur gear 22 and drives the same, the external spur rack 21 meshing With and driving the spur pinions 30, mounted by shafts 31 on frame 32, attached by bolts 33 to braces 17. Pinions meshr with `and drive the spur gears 34, attached by bolts 35 and angleirons 36 to thc receptacles 6. Thereceptacles 6 are so attached to gears that they do not swing thereinbut'rotate therewith. The housing /lfreniains stationary at all times. The arrows indicate the direction of rotation oi the various parts. y

The dimensionsof gears 34 are calculated with relation to the dimensionsl of rings 7,

so that While rings 7 are revolving, the

equilibrium of the contents of receptacles 6 is maintained on an even level therein because of the rotation or' gears 34. From the central driving pinion or gear 28 to the outward extremitresof the train of gears, 1n-

cluding rings 7 andv gears 34, the mechanism is vplanetary in its nature.

Rings 7 lare caused to revolve by reason of their being connected by braces 17 to vframe 32, Which is driven by the inner spur gear 22 and gear 29.

'Braces 38 are attached. to braces 1.7, and each brace bears rollers 39 and 40, which run ontraclrs 10 and 12 on gears 34. e

The rollers 23 and 24 are intended for anti-friction purposes. It isto be understood that gears 34 and gear 22 are so formed, angular in crosssection, that two tracks thereon are formed, on which the abovementioned various anti-friction rollers run.

The shaft 27 is driven by motor 41 or any other suitable source of power, in a small device, such as a bookcase for instance, a hand vcrank could be attached to shaft`27.

There is a plurality of rings 7 and receptacles 6 extending from one ring to the other, the Whole forming ak rotary frame. Preferably both ends of receptacles 6 are open. 1

The receptacles 6 are not mounted on shaft-s or other supporting means, but are held in position by rollers 11 and 13, and 39 and 40, which prevent gears 34 from moving longitudinally or laterally or otherwise than rotarily.

In the drawings I have shovvn the ring 7 driven from the inside or from the central receptacle but it is obvious that the source of 'power may be located Without the rings 7 at any p'ointon its circumference but this would necessitate a much larger gear aroundthe circumferential area of ring 7 ,spirit of this 4invention or the means for dr than the prei-'erred form of internal spur gear 22 shown.

It should be clearly understood from the foregoing that the external spur gear 21 is stationary With reference to the frame 3 and imparts motion to the idler 30 only from travel of the idler 30 around external spurgear 21.

In airplane bodies, a heavier load in one receptacle 6 Will result in causingI gequilibrium of other receptacles 6 by forcing them by gravity to equalize the Weights in all, tending to equal distribution of Weight in all parts oi the body. Ordinarily a brake will hold the receptacles 6 stationary, but this brake `will be released when rising in the air. I

In case the ends ol.'A receptacles 6 are closed and a side thereof left open, beveled gears may besubstituted for spur gears 34 and will preferably'be attached at the said ends.

Beveled gears may be substituted throughout for the spur gears shown in the drawings. Y

Having thus described this invention, I hereby reserve the benet ot' all changes in form, arrangement,order, or use of parts, as it is evident that many minor changes may be made therein Without departing from the scope of the following claims:

I claim: Y

l. The combination of a central driving shaft, a gear driven thereby, an idler gear7 an internal spur gear andan external spur gear, the said idler gear meshing With the said said gears, and a plurality of receptacles borne by the said frame.
