- To'cll whom'it concern:

it known thatI, Cannes D. SEEBER- can a citizen of the United States, residing at Yonkers, 1n the county ofWestchester and State of New York, have invented certam new and useful. Improvements in Conveyers, of which the followingis a specification, reference being had therein to the accompanying drawings.

n My invention relates to conveyers, and

especially to that class of conveyers wherein a traveling carrier or foot-way moves in an inclined runto transport passengers or frei ht between differentlevels. r

T e object of the invention is to provide class or type of machines, and especially to form a rest or barrier whi h on the trans-.

;in Fig. 1.

clined runs or

ways

14 and 15 between landings l6 and 17 at different levels, as shown The tracks terminate adjacent Q end carriages or reversers at difierent levels and winch 1n the present form are shown as revolving spiders 18 preferably formed with seats 19 adaptedto re -eive wheels 13.

At predetermined intel .s along the conveyer I provide abutmeni or rests against which merchandise or the wheels of trucks bodiment these rests are constituted by see- 3 tions of the 'conveyer capable of rising up 1 somewhat above the normal line of the concertain novel and useful features in this porting run projects above the line of the I conveyer and against which the merchandise may rest or upon which the passengers of the adjacent portions of the conveyer.

The invention consists in the constructions, arrangements and organizations of parts hereinafter set forth and then pointed out in the appended claims.

In the accompanying drawings illustrating the preferred embodiment of my present a device illustrating the present invention; Fig. 2 is a central sectional view of the parts taken at the upper end of the incline; Fig. -3 "isa sectional view on the line 33 of Fig. 2, pants'being'broken away, and Fig. 4 is 'a top plan view of a portion of aconveyer showmg a barrier and its associated parts with some of the parts omitted and others broken awa .Tiie machine comprises a conveyer pref-. .erao'ly composed of a series of connected secin Fig. 4; one of the end-links 20 is omitted veyer and presenting barriers orblocks on the transporting run. For this purpose certain of the sections are'made in skeleton form consisting of end-links 20 connecting I a pair of adjacent axles, and pivoted upon 1 the leadingaxle of each pair (considering ma stand, and which at the exit landing is I 'ly lowered into substantially the line 1 the machine to travel in the directionv of the arrowin Fig. 1) between the end-links by suitable ears 11 is a barrier or rest which in the present embodiment consists of a tread or body-portion 21, a riser or closure 22 and end-pieces 23. "In the View shown g to better illustrate the location of the rollers $24, one "of whlch is connected to each end invention, Figure 1 1s adlagrammatic view of of the riser of each barrier by means of an inwardly directed projection or arm 25 carried by the riser. The barriers preferably extend approximately the width of the conveyer, and upon the carrying or transporting run are adapted to stand'above the line or path of the conveyer to form rests or abutments, and at the exitlanding'are lowered into substantially the line ofthe conveyer to pass. or disappear below the ordinary floor-landing 17. In the form shown the tread or body 21 is curved to conformto the curvature of the spiders 18 for this purpose, and the risers are also curved as shown in order to lie close to the succeeding axle in all positions of the barrier and thereby prevent gaps between these parts during the rlseand fall of the barrier.

The rollers 21 travel on auxiliaryjorguide tracks 26 one at each side'of the way, and which are inside the supporting tracks 14a and so positioned as to hold the barrier raised or inoperative position above the conveyer The axles are provided with wheels orf travelers 13 adapted to run upon suitable tracks extending in upper and lower mon the transporting run. In order to accommodate the device to the ordinary floorlanding, as at 17 and so that the latter-need:

, not be provided with any openings through which the barriers disappear, I provide means to automatically lower them at the upper landing. For this purpose the bar:

the spiders are provided with-downwardly' riers are loosely mounted on their associated axles l2, and the tracks 26 which are lnslde curved end-portions 27 as shown in Fig.2. The-tracks 1 t terminate adjacent the spiders 18, which are arra11ge d-in pairs upon a suitable shaft 28 to which they are keyed and by-which. the, machine may be driven from any suit-able source of power.

-When the barrier reaches the top of the inclined portion ofthe run or way, the roll:

ers 24 pass around the curved track sections 27, so that the-barrier is lowered or folded down to the position shown at the extreme right of Fig. 2. The dotted line 29 in Fig. 2 shows the general path of the barriers, thecurvature of the tracks 27 beln-g such as to gradually lower the barriers Irintothe line of the adjacent sections of the conveyer, so that they all passunder the landing 17 in a uniform path.

WVhen the barriers pass around the spiders 18 the rollers 24: pass upon the return guide tracks whiclrhold the treads of the barriers in' line with the other sections and as they emerge from below the entrance land-- 0 v a a with theordlnary straight or plane-faced floor-landing. For example, in conveyers in 16. t a w 'lhe present invention eliminates all open ings and slots at vthe landings and enables a conveyer havlng barriers to cooperate employing upwardly projecting dogs or arms it is necessary to provide slots 01'.

openings at the landingthrough which the arms or do s may pass; but with my invention all sucn,open1n -s are avoided and the well as at lesser ones.

attendant risks eliminated, as the barriers automatically .fold or close down into the path of the carrier and so pass the ordinary floor landings.

It is of course obvious that the barriers are effective at different inclinationsof the conveyer, and therefore this form of conveyer isespecially applicable to docks or wharves where by reason of difi'erenc es .tide levels tllGlIlCllllittlOD .of the conveyer varies; with the ordinary conveyer'there are times of the tide when they cannotbe used, as when at low tide the angle of inclination is less than the angle of repose of the commodity transported, butthe presentform.

may-beaised at steep inclines or anglesas While the device is especially, adapted for transporting freight, it may ofcourse be uscdas a passenger conveyer; each of the barriers constituting in efiect a ste -section as thepart 21 tormsa tread sur ace, and the part 22 a riser. When these parts are curved, the barriers preferably are substan- 'tially cusp-shaped- The risers or closures need not be used as these treads, 21 form barriers in themselves, but the risers are useful to close all gaps between the-treads andsucce'ssive sections and so are preferred "in practice. The barriers may be used in conveyer-s having horizontal runs, but are especi'allynsetul where the run is inclined.

It is obvious of course that where a 0011-. veyer extends between three or more land-' ings, as where, it passes below one or more intermediate landings, the barriers maybe lowered to the line of the conveyer at these intermediate landings by employing my present invention so that they will pass under the intermediate landings and reappear beyond them to again serve as rests upon.- the run to the next landing. In this ar- 1"angement the conveyer would be utilized for service between adjacent landings, and not for through service between alternate or non-adjacent landings.
