SPECIFICATION forming part of Letters atent No. 777,1'7'1, dated December 13, 1904.

Application filed May 17, 1904. Serial No. 208,364. 'No model.) i

To (LU rfi/mm. 1'/ 11ml/ volw/'Wla- Beit known that l, LAwnnNon ABRAHAM, a citizen of' the United States, and a resident oi the borough ot' Brooklyn, county oi' Kings, city and State ot New York, have invented certain new and useful Improvements in Conveyers, of which the following is a speciiicatioii.

My invention relates to conve'vers tor delivering parcels or goods at diii'ercnt floors ot' a building, and has Afor its object to provide a simple device which maybe used beth inasccnding and descending and which will automatically discharge the parcels or goods at the various `lloors tor which said parcels er goods are intended.

'lhe invention will be fully described hereina'f ter and the features oi novelty pointed out in the appended claims.

Reference is te be had to th i"accompanying drawings, in which Figure l is a diagrammatic elevation of a conveyor with my invention applied thereto and with parts in section. Fig. 2 is a plan. Fig. 3 is an enlarged fragmentary side view ot the conveyer, with parts in section, as it ascends. Fig. 4 is a front view oli the same. Fig. 5 is an enlarged fragmentary side view oi the conveyor, with parts in section, as it descends; and Figli isa lrontelcvation thereof.

A B are rollers jourmrled upon shafts A.' Il', respectively, and arranged to'support the traveling belt (l. lower` may be applied to the. rollers inanysuitable manner. Upon the belt (l pivot-blocks l) are secured at spaced intervals in any convenient mam'u'r as, for instance, by riveting. Upon these blocks l) are pivotally secured carriers comprising skeleton trames 1C, having' arms E' and lgi'or steadying the said frames and standards F and F' at the outer edges of said skeleton frames. Shelves (l and (-i are hinged at ll and l-l' upon thesaid standards Fand l1". ',lhe said shelves G and (1U are connected by a rod l, the pui-posi et' which will be more fully de scribed hereinafter. 'lo prevent undue wear upon the bei.. t), reinforcing-strips U', of metal or other material, are secured to the said belt (l at the points where the ends ot' the arms 1G' and li will` abut against said strips.

J is a chute situated one on each floor of shown.)

ed upon suitable Framework, (notshownJonel set tor each licor, and M represents arms iorning part of or secured to the shelf (lr, which extend outward so as to be in a position to engage the rollers L as the belt ascends. The chutes J, however, are not in the path of the arms M. (See Fig. Similar arms N extend l'roi'n the inner edge ot tl ashelf Gr', said arms being arranged to engage stationary cam-surfaces (l as the belt descends.

l) represents belt conveyors, one for each iloor, traveling'over rollers l, upon which the parcels are adapted to be discharged as the cenveyerdescendsn Upon the shaft of the rollers I" is pivoted a short chute (J, having a weight Q' secured thereto.

1t will be undcrstoml that the arms M N of the shel\f'es("r( res icetively are soarraneml that no two sets of arms M and N engagewthe same rollers L in ascending or cams (lindescelming. (klee Fig. 2.) 'lhus the shelves (i and may be marked to corresl'iond to the floors upon which they are `intended to discharge the parcels or goods. ln a direct line with cach ol'I the rollers L and cams on the inside. oi' the belt (.3 are placed rollers R.. extendinp `..ross the width ol the said belt and suitably mounted on stationary Framework. (Not The purpose olE these rollers lt is to prevent the belt @from bulging inward and discharging the goods or parcels prematurely. Similar rollers S for a similar plu-pose are so placed that they will be just opposite to the lower ends of the arm IC in aseemliltgI and opposite ll in descending.

`The operation of the device is as follows: lower is applied in any suitable. manuel' to drive the conveyer. the shelves all being in thc position indicated alt the upper part of Fig. land in dotted lines in Fig. 3. It will be noticed that all of these. shelves incline toward the belt, each shelf being marked to correspend to one floor oi the building-that is, the

range d n at the second door with a WZ," and'l nwtnere heine" two shelves for each door, t dischaLge in ascending and the other escending. li parcels or goods are new "ed on 'the sh elf 'marked l, the said goods remain on said lshelil until it rea-ches the floor. soon as the outer edge of the reaches the part l oi' the chute @l the fart l will tilt on its pivot (see dotted 1 l v g'. and he held in this position until shelf has nassed, whereupon the part l l he swung hach 'to its initial position under the inluence of the weight K2, it being nnderstood that the pi 1'ot K is constructed as c. rule-joint and capable ot' swinging only in one direction Yfrom its normal position. New continues to ascend. the arms M ontac' with the roller L on the first licor, ie shelll (al will be swung on its pivot H position shown in the lower j `rt oil Fig. .'"l a certain angle is reached, Wnereunon ,foods or arcels will slide ofi the sheli and f i edepositedon the chutednvhichniaylead to a suitable table or hin, it will he under- ;od that the inner edges oii the parts l are insifl eo'f the outer edges oi the shelves G? or5 in other words1 the part S is overlapped by the disc'nx rge end of the shelf Li. The K are @ed for the sole p'nrpose ol allowing' them tov sii/ung' ont of the path of the shelves. The here L :mey disposed that the tipnin g ol the initial position. To prevent the sn being swung too far, the said i yed by a rod l to 'the shell il", against the levier the conveyor con Meend the itl will ride pest .and the shelves will drop hach position hy their own vqht. pointed ont, the rollers l; are o on ach Toor and the arms intended to vfin spaced to correspond, so that ire slitte and so that the arms ot' lo. ly engage the rollers on the which it is intended to discharge and i, ass all 'others without engaging' them. ii dessending;` the shelves G become the' unper on.' s, the h' engage the cams Op and the Garethns tilted to discharge th needs toon the conveyer in the manner as explained in regard to the she os il, the shelves G in this case acting as a stop to prevent the shelves Gr from being tilted too tar, the shelves returning to their initial position as soon as they pass the cams O. As the shelves continue to descend the vouter of the shelves Gf will lrst ahnt the 'part Q and swing the saine on its pix and on, and then the outer edge of the shelves G will engen-e the part and a, ain swing' it on its pivot and also s on, the said part Q heingreturned its we gglit it will he understood that the cams C# are so ar that the shelves il are fully tilted to i shelves to l,

i shelves at the moment discharge heore the outer edges of the shelves G touch the part Q. The purpose of the part Qi is the saine as explained in regard to the part le; and the cams O and the arms N are arranged exactly as the arms M and the rollers L-tliat is, so that each shelf will discharge only on the loor for which it is marked and on which the spacing of the cams corresponds to the spacing of the arms lt will be understood that all of the stationary parts are mounted on suitable framework, which l have omitted Ifor the salie of, clea'rness.

lVhile l have shown what l consider at present the hast means ot' 'carrying ont my invention47 i desire it to he' distinctly understood that various modilications may he made Without departing from the nature of my invention.
