To all whom, t may concern. f

Be it known that I, FRED L. SIMON, a citizen of the United States, residing` at rBaltimore, in the State of Maryland, haveinvented certain new and useful Improvements in Conveyers; and I do hereby declare the following to be a full, clear, and exact description of the invention,`s'uch as' will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to conveyers. Among the objects of my invention are Io provide a portable conveyer which can purpose of'stacking goods in tiers.

To provide a portable conveyer comprising carrying fingers whicliare spaced apart, said fingers being arranged uponr endless chains which form the conveying element so that said carriers can be introduced beneath a platform composed of spaced `apart'load-` ing bars having but a slight elevationy fromk the floor. y n

By the Iattainment of this object, I avoid the heretofore necessary operationof lifting the article to be transported to a considerable height so that lingers could be moved thereunder in order to engage said article. n

To provide a simple, cheap, lightand portable conveyer which can be'adaptedv for the transporting of objects having@variousy shapes by simply changing the shape `of the carrier or the platform, or both.y n These and further objects of my invention will be set forth in the following specificar tion, reference being had to the accompanying drawings, and the novel means by which said objects are eifectuated will be definitely pointed out in the claims.

In carrying out myinvention Iv make'use ot' the instriunentalities illustrated inthe accompanying dra\vin,gj:--` n i Figure 1 is a side view` partly in section, of a conveyer constructed according to my invention. n

Figure 2 is an enlargedview of'some of the parts shown in Figure 1 lookingin the direction of the arrowv 2 in said Lligure.

Figure 3 is a section along the line 3 in Figure 1 looking in the direction of the arrows.

Figure 4 is an enlarged detailed view of parts hereinafter referred to.

In the drawings 10 represents a boom which is composed of channel irons such as 11 which extend `'from the slidey Aa.

end kto end of said boom for the purpose lof` NrofFFICE; i

guiding the conveyer rollers12. 'The chany nelirons llare spaced apart and maintained in correctr relative fposition by lat-tice Work such as 13 andnear each end of said boom a plate such 'as 14 1s secured. In the plates'14 there areprovided bearing'for theshafts 15 j and 16. y The shaft 15 is mounted in housingsv such as 17 which are supported upon the carriage 18. The carriage 18 is mounted upon a pairof Wheels such as 19 (anda castor 20.

A guide 21 is pivoted as at 22-to the carriage liand a slide 23, pivoted at 24 to a plate 25 secured to the boom, slidesfreely within the guide 21. Aliand orpowe'r operated Winch f,

2Giis mounted upon the yguide 21and connected by a rope to the hook 27 'secu1ed to Saidiwinchis for the purpose of raising or lowering the boom A10 in order to deliver the articles to" any height desired as hereinafterexplained.` IVhen the boom 10 is raised to theproper heightit is maintained in the said position by the engagement fof the lpawl 28 with the' ratchet wheel 29.

` Pivotally mounted as at 30 upon each side yof the carriage 1S near oneend thereof are' a pall otleversl, the lower ends of `which y rare pivotally connected to aflange*provided `at the sides of the supporting pla-te 32. A

knut is swivelled'in any approved manner at',

the upper endofeach of the levers 31 and a screw 33 isthreaded'in said nut. Saldscrew turned Aend 37.

Sprocket LWheels 38`and" 39 lare rigidly mounted

uponthe shafts

15 and 16. A pulis revolubly supported by bearings 34 and yis "revolved a handle y The supporting 1 plate 32 carries a plurality of loading bars 36, each of` which is, provided .WithdanupY 'by' the electric motor or other 'source of vpower 43 through the intermediary of the reductiongearing 44a. Sprocket'chains such I as 44 extend the length of the boom 10 yand y around the Wheels 38and 39. A plurality of shafts suchjas 45 vis secured to said sprocket chains and Vthe rollers 12 are revolubly mounted `on the ends ofsaid'shafts thus serving to support the chain i between cthe Wheels 38and39.; f

At Whatever j portion of thejchains 44 Iit is desired to attachy carrying fingersfsuch as 46, tivo! of the shafts 45 'are located closeto;

gether, a plurality of links 47 is mounted f be noted that the bars 36 are so located that y the lingers 46 will pass between same. One of the outermost fingers 46 carries a tappet 50` which is located to strike the cam 51 formed upon the boomlO for a purpose hereinafter explained. y Y

Any desired plurality of the rollers 12 'may be grouped adjacent the fingers 46 in order that the shafts 45 may supportthe weight of the article 52 that is being transported and a chain such as 53 has one of its ends connected to one of said shafts and the other end connected to one of the fingers 46. Only one tappet 56 and one chain are shown in the drawings but itr is to be noted that more can be used if desired. purpose hereinafter,explained latches such as 54 are revolu'bly mounted upon the shafts 45 and ysaid latches are arranged to engage pins such as '55 which are mounted in the ends of one of the outside lingers 46. Each latch is providedV with a tappety 56 located to be struck by the pin 57 which is secured to the boom 10. y

A chute 5Scomposed of a plurality of-bars located similarly to ythe bars 36 so thatthe finO'ers 46 can )ass therebetween is riOfidl secured to the arm 59 and the latter is pivoted as at 60 to thebooin 10. A brace 61 is pivoted as at 62 to the arm 59 and there is swivelled inthe end of the ybrace 61 the screw 6?,"which is threaded in the nut 64; The nut 64 is swivelled upon the boom 16 and is turned -by the handle 65.

' The operation of my improved conveyer is as follows The operator turns the yhandle 85 so as to move the levers 3l in a clock-wise direction Athus lifting the supporting plate 32 from the floor. The carriage 18 can thenbe wheeled to yany position desired.

The oper-alor then applies power'. to the winch 26 and raises or lowers the booni 10 so as to place the chute 58 in the proper location for the delivery of the articles where desired. rlhe operator then drops the pawl 2S to maintain the boom `in said position. y

The operator then turns the' handle65 in such a direction as to bring the plate' 32 in contact with the floor. He then starts theinotor43 and delivers the articles upon thetop of the bars 36 as shown atthe left of Figure 1L It isto be noted that', in thus delivering the articles the upturned ends 37 locate the articles in correct position to be acted upon by the fingers 46.

v VAs the chains 44 move in a direction of the y'arrow 5 on. the under side of the boom r16 For "a they bring the tappets 56 against the pin 57 thus removing the latch 54 from the pin 55 and allowing the fingers .46 to drop upon the plate 32 between the bars 36. The continued mot-ion of the chains 44 then moves the fingers 46 end-wise between'said bars vand between the article to be carried and plate 32. Asthe chains 44 move around the wheel 155 the-chain 53 becomes taut and lifts the fingers 46 through thebars 36 into contact with the article and then carries the article on the upper sidev` of the booin 10 until it slides from the conveyer when the chains 44 move around the wheel v239. Then the article Slides from the conveyer it drops onto the chute 58, and the latter by means ofthe adjustable brace 61 may be set at any angle to deliver the articlewhere desired.

After the article drops from the conveyer onto the chute 56 the fingers 46 mayy or may not drop of theirl own weight, but in any case the tappet 50 comes into Contact with the cam 51 and said fingers are moved upwardly until the'pin 55 engages the latch 54.

The fingers 46 then move on the under side of the boom 10 in the direction of the arrow 5 until the latch is unlocked and saidv fingers again engage the plate 32.

Thus it will be seen that I provide a conveyer capable of being readily transported from place to place 4and capable of piling articlesin tiers.

It is further to benotedv that by; arrangi ing the ngers 46 to have an eiid-wise movement between `the bars 36 y it becomes lunnecessary to lift the articles to ajconsiderable lie-ight from the floor in order to bring themv into operative relation with the conveyer as has heretofore been necessary. This improved result l obtained by the end-wise motion ofthe fingers46 witlireference to the bars 36. y

It is to be noted that the winch 26 is merely representative of any means for elevating or depressing the booni 10. The motor 45:3 and the mechanical connections for revolving the vsprocket wheel 15 are representative of any source of power and an;7 form of connection therefrom to said wheel.

`While I have shown one forni of mechanism for elevating and depressing the plate 32, and one form of mechanism for controllingfthe operation of the fingers 46, it is to be understood thatthese mechanisms have been shown and described for illustrative purposes only and in no wise to llimit the scope of my` invention for many changes may be made therein without departing from the spirit thereof.
