CONVEYER.

Application filed August 23, 1924.

This invention relates to improvements in conveyors.

The main objects of this invention are:

First7 to .provide an improved conveyer which is Well adapted for the loading and unloading of cars and which may be readily set up or adapted for the particular requirement or conditions. Y

Second to provide an improved portable conveyor which may be `quickly set up or disassembled and when set up is capable of carrving heavy loa-ds7 such as bags of cement or t like.

l@bjc-cts pertaining to details and economies of construction and operation of my invent-ion will definitely appear from the detailed description to follow.

i accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invent-ion is clearly illustrated in the acapplication, in which: Y

comnan ino" draivin' formin a art of this l b b Serial No. 733,776.

neferring to the drawing, l provide a main unit designated generally by the numeral 1 and a plurality of auxiliary or supplementary units designated generally by the numeral 2. Only sui'licient of the supplementary units are shoivn as are deemed necessary to show an embodiment and the use of my improvements. Y

The main unit 1 is mounted upon a truck 3 extended at one end to provide a platform el, this platform having an upright frame 5 thereon constituting a support for the suplemental units When not in erected position, thereby providing storage and transportation facilities.

The main and supplementary units are quite similar in structure, the terms main and supplementary being largely matters of convenience in description.

The main unit is provided With side members 6 Tvhile the supplementary units have corresponding side members 7. Each unit has a carrier comprising carrier shafts, both carrier shafts 8 -of the main unit being driven shafts. The supplementary units have carrier shafts 9 and 10 corresponding to the shaft-s 8 of the main unit, the shafts 9 being driven shafts.

The carrier shafts are provided with sprocket Wheels 11 disposed Within the side members of the units and carrying the sprocket chains 12 which have slats 13 secured thereon, the conveyer belt 14; being disposed over these slats.

The main unit is provided With a. pair of driving shafts 15 disposed at the sides and longitudinally thereof and connected to the povver shaft 16 by Worm gears 17 and 18, the power shaft being connected to the motor 19 mounted on the truck by means of the sprocket chain 20 arranged in the housing 21.

The supplementary sections are provided With longitudinally disposed driving shafts 22'carried by the bearings 23 and the gear boxes 24s Which are provided with suitable bearings for the shafts.` At the outside of the bearings 23 and the gear boxes 24 are coacting shaft coupling members 25 and 26,

the coupling member 25 being adapted to enter the coupling member` 26 and having a lug 27 adapted to coact with the lug 28 so that these shaft-V couplings may be engaged by :a longitudinalvmovement and there is little likelihood of the lugs interfering with the engagement.`

The units are provided with couplings, the couplings being mounted on the ends of the side members, those at one side consisting of the knuckle coupling member 29 and the coacting pintle coupling member having pintles or pivots 31 disposed vertically. The knuckle coupling member 29 is provided at diagonally oppositel corners of the main unit and at the outer ends of one of the side members of the supplenientary units, the coupling members 30 being provided at the inner ends of one of the side members of the supplementary unit. At the oppositeA side the units are provided with telescoping couplings consisting of the saddle members 32 and the projecting lugs 38 adapted to enter the same. Latches 34 pivoted at 35 engage the keepers 36 on the sides of the coupling members 3 2. Y

With the parts thus arranged the pintles 3l are engaged With the coacting coupling member and the unit swung sidevvise engaging the coupling members 32 and 33 and at the same time engaging the shaft coupling members 25 and 26.

The shafts 22 are provided with Worms 37 enacting with theivorm gears 38 on the carrier shafts 9, these parts being enclosed in the gear boxes 24. The shafts 8 are 'provided with gears 38 coacting'ivith driving Worms 39 on the shafts 15 in the same manner as Worm 37 and gear 38 in Fig. VI. The shafts l5 are provided with clutch members 4.0, reacting clutch 41 being Vcontrolledby the shifting yoke 42. A second shifting yoke 43 controls the clutch member lli which controls the connection to the shaft 8'. The details ofthese clutchesare not illustrated as' I employ a Well-known type of jaw clutch satisfactorily. y

The shift lever 45 carries the pin 4:6 to which both these yokes are connected.` This shift lever is connected by the link l? to the pin 4G of a duplicate clutch mechanism for controlling the, connections for the other driving shaft of the main unit, the connections being arranged so that when one is engaged the other `is disengaged, thereby providing means for driving. the conveyer `of the main unit in either direction, and also driving the shafts 22 of the supplementary units vvhen disposed at either end of the main unit, thereby permitting vthe arrange ment of the supplementary units for the loading or unloading of either end of the railvvay car or the like.

4The' main unit is preferably provided with sid boards' f8 'tvhich assist in Vretaining the articles thereon when throivn'uponthe con.- veyei ofthe main'iun'it orv when' discharged thereto. from a supply or delivery 'c Onv'eyer.

In the modification s liovn in VIIIv the'main rinitis' arrangedto 'discharge'fat right angles to a similar unit 49, the supplem'entary units 2 being associated with the unit e9 as has been described.

I have not attempted to illustrate or describe other modifications or adaptations of my improvements as I believe the disclosure made will enable those skilled in the -art to embody or adapt the same as may be desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is :w
