SYSTEM OF LOGOMOTION.

Specification of Letters Patent.

Patented Sept. 4., 1%13.

Application filed November 13, 1916. Serial No. 131,165.

5 This invention relates to a system of lo comotion or apparatus, for the transportatlon of both freight and passengers. One of the objects of the invention is to provide a device of this character that will furnish such transportation by a gradual acceleration of 15 movement of the articles carried, with both safety and comfort. v

Another object of the invention is to provide a device of this character that can adapt itself to an irregular path of move ment; the object or passengers can be transported ma path that diverges laterally, and which conveyor also is adapted to carry passengers both up and down an incline, as

well as on a level.

In the accompanying drawings illustrating embodiments of my invention, Figure 1 is a side elevation of a portion of the device.

.Fig. 2 is a cross section through the same on the line 2-2 of Fig. 1. Fig. 3 shows the planes or bars closed together, and Fig. 4L shows the same drawn apart. Fig. 5 shows the application of the planes to a step formation. Fig. 6 is a vertical section, partly in elevation, of a modification of a motive power as applied to the planes. Fig. 7 shows the step formation for the ascent. Fig. 8 is a detail of the planes. Fig. 9 shows one of the bars bent to form a lug or hook. Figs. 10, 11 and 12 show modifications of the bars. Fig. 13 shows the device operating on a decline. Fig. lt shows a bar having a rectangular frame formation. Fig. 15 shows the bars adapted to assume lateral deflections. Fig. 16 shows the slotted connections of the bars. Fig. 17 is a modified section. Fig. 18 is a plan view of the parts shown in Fig. 6; andFjg. 19 is a modification of the latter.

In the drawings the conveyor is shown as composed of a series of connected or articulated article-engaging sections. and means is provided for supporting and guiding the sections, both on a level and also to pass up an incline and then down another incline support to resume the former level. The planes or sections denoted generally by A, are shown as composed of bars S suitably connected in each section at one end, as by rods P extending transversely through slots 2 in the bars, as shown in Fig. 16. The bars in adjacent sections overlap, and the free ends of the bars of one section rest on the cross rod P of the bars of the adjacent section, as indicated in Figs. 3 and 4:. This will permit relative movement longitudinally in adjacent sections, for the purpose of producing an effect of acceleration in the conveyer, and also a retardation in the speed of ad- Vance of the sections, as may be necessary to return to former speed, in an endless conveyor.

In Figs. 1 and 2 a series of shaftsm, m and 97 2 are mounted on hearing members M, which shafts carry supporting pulleys B. It will be seen that these pulleys are arranged at close intervals so that two of them support each of the sections A. One of the shafts is shown as driven by a motor 14., and this shaft carries a sprocket wheel 25 that serves to drive an endless chain 26. This chain is provided with projections 27 adapted to engage with projections 16 on the bars S of the sections, shown in these views.

A pulley It on the driving shaft M connects by a belt G with a pulley 29 on the adjacent shaft 777/, and a smaller pulley 40 connected with the pulley 29 serves to drive by a belt 11 a pulley fast on a shaft m by means of which the supporting pulleys B on this shaft m will be driven at a slower speed, and hence the bars S while engaging this pulley will travel. at a reduced speed. The shaft m carries a small pulley 43 connected by belt a l with a larger pulley 45 supported on a shaft m Hence the pulley B on shaft m will have a still further reduction in speed than the other pulleys or wheels. By this means a gradual acceleration is provided for the conveyer moving in the direction indicated by the arrow in Fig. 1; this being permitted by reason of the relative longitudinal movement of the adjacent sections.

The projections 16 on the bars S may be hinged extension (Z.

formed by bending one end portion on itself to extend downwardly, as shown in Fig. 9, which thereby obviates the use of an additional lug attached thereto. 1

In Figs. 1 and 2 the cross rods, P are shown provided with extensions P that project upwardly as shown, their upper ends seats R- hinged thereto by supports B.

These seats when swung down to'the' hor1-' z-ontal position as indicated in Fig. 2 are for theconven'ie'nce of passengers.

The apparatus or system as described so far is adjustable for use on a level. but to accommodate inclines I arrange the' conveyer to assume a step formation, such as indicated in Fig. 7. For this purpose I provide a guide rod 3:2 that is engaged by cross rods C passing through the bars S, while the said chain 26 engages guide wheels 30,

as'shown in Fig. 7. For such use I further provide extensions (Z pivoted to the bars S at e, that will act as the rise portions for the treads composed of the bars S. A modification of the bars is shown in Figs. 1012 in which the bars have a right angled form caused by an integral extension 17 at one end that carries the connecting rod P, while the other extremity is provided with the lVhen moving on a level their position is as shown in Fig. 11; while on the incline their position is as indicated in Fig. 10. In Fig. 13 is shown a guide rod X extending on a level and then inclined downward to permit the'descent of the parts as shown in Figs. 10-12. The chain 26 here shown passes around a guide pulley 30 and then travels down the incline. In Fig. 5 is shown a modification in which the sections are composed oi rectangular members A These members are provided at oneend with slotted plates 5, that are engaged by bolts 2' on the adjacent member A. By this means the adjacent members are relatively movable in a vertical path. This willper'mit them to assume the step formationon both an incline and a decline in their forward direction, as clearly shown in Fig. 5, wherein the guide rod X is first deflected upwardly, then extends on a level, and then extends downwardly to the former level. In this view the chain 26 is deflected by guide rolls 30 as indicated in Fig. 13.

In a system of this character involving the use of a large number oi? the shafts and guide rolls, is obviously necessary to provide lubricating means for the rolls or pulleys. As shown in Figs. 2 and 6 the axles m of the pulleys are provided with longitudinal grooves 71.. I provide a reservoir 0 from which extends a wick tube 00 provided with a wick w. The tube extends to the groove It and the wick projects beyond the tube into the groove. The wick will absorb the oil in the reservoir and will convey it to the groove. If desired the reservoir 0 may be in the form of a pipe extending along from axle to axle,

' and hence it is only necessary to keep the pipe supplied with the lubricant. In order to regulate the position of the wick tube, the pipe 0 may be turned on its axis as indicated in Fig. 6 by a handle w.

That the system is susceptible to changes because of localconditions, is obvious, as for instance, the lapping ormeshing of the plane surfaces may be lateral, as in Fig. 17, instead of longitudinalas disclosed in the preferable form, or, the planes may have the supporting wheels directly attached'to them'orbe supported by anotherrolling or sliding meansand other such modifications would Fig. 1, to apply the power. A turn-table 4:6

1s shown having a gear 4:7 that revolves on a shatt 19, suitably supported in a'step bearing 52. A worm gear 50 connected with a motor larevolves the turn-table The lugs 16 shown in Fig. 1 projecting down trom'the planes A, engage the teeth of the wheel 47 and hence the'chain' revolves around the wheel. But if desired, the planes may advance in a slightly deflected path l-S instead of making a halt revolution. These turntables, of which there may be a number in a given system, may vary in size for application of the motive power through 4-1. 4.3, 417, (see Fig. 6) or deflection ofthe same as the case maybe.

In Fig. 19 the turntable 51 is much wider and extends across the path, to permit the gear 5% to pass under the wheels on one side of the planes. A bridge 55 permits the wheels to pass over the gear.

This turn-table feature of the system is'. open toa variety of applications and uses, as for instance, the article-engaging units received by it may be articulated (joined) as shown in the preferred form illustrated or separate and still be within the scope of this invention.

It is self-evident that instead of the revolving'means 17) for the application or deflection of the powerbeing of one general I circumference, the same end may be attained, possibly to better local advantage, by the substitution of a number of smaller revolving means, together completing the said gen eral circumference.
