INVENTQR ATTORNEY ,UNITED STATES rarsur,rr efs fl CHARLES ALIBIN NELSON, or nAsrr BE LIN,--coivnno'rrou'r.

ELEvA'ron nn CONVEYEB ArrARArus non BRIC -Yeahs} I To all whom it may concern:

Be it known that I, CHARLES ALBIN NEL- SON, a citizen of the United States, resid ing. at East Berlin, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Elevator and Conveyer Apparatus for Brick- Yards, of which the following is a' specification. g V 7 My invention relates to improvements in elevator and conveyer apparatus for brick yards, and the object ofmy improvement is to produce a combination of elevator apparatus and conveyer apparatus for use in brick yardsand that is adapted for use in 1 handling the bricks in unbaked condition intermediate the drying in the yard andthe stacking for the baking, or, more part1cularly, for delivering the dried bricks to the setter for stacking inthe usual manner for such baking, the bricks'being delivered in groups on pallets, and the pallets after the bricks are removed being returned to the same side of the'apparatus from which they were delivered. Y

In the accompanying drawing:

Figure 1 is an end elevation, in diagram-' matic form, of my improved elevator and conveyer apparatus housed in operative position in a brick yard shed. I

Fig. 2 is a similar view, on an enlarged scale, of the apparatus shown in Fig. 1.

Fig. 3 is a side elevation of the same. i

I Fig. 4 is a side elevation as viewed from the opposite side from Fig. 3, of the yoke connection and adjacent parts of the delivery roller conveyer for the loaded pallets and the cable return conveyer for the return of the unloaded pallets.

Fig. 5 is a plan'view of the same. Fig. 6 is a fragmentary View, on a still further enlarged scale, ofythe loaded pallet and the pallet hangers. r 1

Fig; 7 is. a plan'view of the same." 'My'improv ed elevator and conveyer apparatus for brick yards is positioned so as to extend across the main shed '10 of the brick yard housing in'which the bricks after dry- .ing are stacked for baking,;is supported at one end, at the left end asshown; in Fig.1, on a car 11 for conven ence ln'movlng along 0 V the length of the vmain shed-l0,,theicar 11 traveling in the leftL' 12, and in the right L 13 is an overhead track 14 that supports a carriage 15 so as to be moved to correspond with the shift of the positionof thecar 11 Specification-ofLetters Patent. Ptmit d'NO 23 19 20 Application filed April "4, 1919.: Serial No. 287,532.

and which y means of hoisting apparatus 3 16 serves as the means for support for the other end of the apparatus. I V

The devices supported by he car 11 com prise a roller gravity conveyer 17 on the'left srdefor receiving the pallets 18 loaded with the dried bricks 16, a secondgravity conveyer'20 of the roller form for delivering the unloaded pallets 18 outward from the machine, below'f'the first mentioned conveyer ll means ad ustable as to'elevation f0I' S11p porting he left end of the rollerfconveyer 21 that extends across-the main shed 10 for,

delivering the loaded pallets to the setters ,for the removal of the bricks; pivotal sup 7 portlng means for supporting the leftfend 'of 'a cable conveyer 22 for deliveringthe unloa'ded palletslS from the righ end of the unloading conveyer 21 't0 the pallet delivery conveyer 20;"elevator apparatus 2 3 ffor; recelvlng the loaded palletsfrom thejrec'eiv? ing conveyer 17 at a relatively low and fixed level and delivering them to the unloading conveyer, 21 at any one of the levels to which it may be set throughout the range of. adjustment; a-motor24c for operatingthe mov ing parts; andshafting and jgearingforioperatively connecting the motor 24 with the said moving parts. I x

.r The conveyer 21 receives the pallets 18 I loaded with bricks 19 at the'left end and during the passagefrom the left toward the right,-due .tothe inclination of the conveyer as provided by the adjustable' supporting means at the twoends, the bricks 19 are delivered so as to be accessible to the setters who are building up the stack at-any position along the width of the stack, and the adjusting means for the endsmentioned per.- mits of raisingzthe conveyer 21 bodily so "as to be accessible for-different heightsasthe stack is built up. a

' Also, the car 11 at one end of the conveyer 21 andthe carriage 15 and track 145- at the other end provide means for shifting the mechanism along the length of the shed 10 to correspond to the building up of the'stack along the length thereof.

A pair of standards 25 extend upwardly from the car 11 and serve as supports for the-ends of the conveyers and other devices J-f' ards'. .A pair of shafts 27 supported by the main standards and positioned one above the other, support sprocket gears 28, and a pair of sprocket. chains 29 are supported by the sprocket gears 28. The chains 29 support the two ends of a bar 30 or equivalent device that servesv as the support for the left end of the upper roller conveyer 21 and the elevation thereof is changed by moving the two sprocket chains 29 in unison.

.Movement of the chains 29 is effected by means of a crank 31 supported by one of the main standards 25 and operatively connected to the lower shaft 27 by means of gearing 32 of any approved form.

The cable conveyer 22 comprises a pair of side frame members 83 that are supported v by their inner or left ends on the shaft 34 guide and receiving device for receiving the and are provided with a shaft 35 at the outer ends or right ends and has a pair of cables 36 that are operatively supported by cable pulleys 37 on the shafts 34 and 85.

The shaft 34 extends across the space between the main standards 25 and has an extension 38 that extends through to the auxiliary standard 26. The cable shaft 34 is driven by means of a pulley 39 on the extension 38 that is connected by a belt 40 with a pulley 41 on the countershaft 42, the said countershaft being operatively connected to the motor 24 by gearing 43.

The right end of the cable conveyer 22 is suspended from the corresponding end of the roller conveyer 21 by means of a yoke device44that permits of changing the relative vertical alinement of the said ends for different positions of adjustment of the two conveyers and the cable conveyer 22 is provided at the right end with a horn shaped extension 45 that extends upwardly in curved form above theend of the roller conveyer 21 that serves as anintermediate unloaded pallets 18 from the roller conveyer-21 and delivering them to the-cables 36 of the cable conveyer 22.

The conveyer 17 7 that receives the pallets loaded with bricks from the yard may be in the form of a cable conveyer instead of a roller cenveyer, as shown, and has the inner, delivery end positioned intermediate the main standards 25 and pivotally connected to the said standards 25 as shown at 65, Fig. 1,, being: generally appreciably below the inner end of the adjustable conveyer 21 at all positions of adjustment thereof.

The loaded pallets are delivered from the yard conveyer 17 to the shed conveyer 21 by means of elevating apparatus of special form, comprising a plurality of. sets of hanger devices 46' operatively supported by sprocket chains 47 I i The sprocket chains 47 are four in number, arranged in two pairs, one pair on each side and separated from the other pair by a space of suitable width to accommodate the pallet 18 and a hanger 46 on' each side thereof. i

The hangers 46 are supported in pendent position'from the inner end of a short shaft 48 that extends through the two members 47 that compose one of the pairs of the sprocket chains -47,-being incorporated in each case in the structure thereof, and they comprise in each casea pendent arm 49 that extends downwardly from the shaft 48 and an inwardly directed platform or base por-. tion 50 that is suitable for engaging-wit the under side of the end of the pallet 18.

A pair of mating hangers 46 engages with a pallet 18 on the end of the yard conveyer 17 when the sprocket chains 47 are in operation, raises the pallet along the left side of the main standards 25, carries the pallet over the top and then lowers the pallet on the right side, and finally delivers it to the left end of the shed conveyer 21. I

The sprocket chains 47 are supported by sprocket gears 51 that are mounted on a lower shaft 52 and an upper shaft 53that are supported 'by the main uprights 'or standards 25. The upper shaft 58. projects into the space between the rear standard 25 i and the auxiliary standard 26 so as to serve as the support for the driving gear 54, which meshes with the gear 55 onthe upper countershaft 56. 1 a I The said upper countershaft 56'is connected with the lower countershaft 42 by means of belt gearing 57. r

As described, the motor 24 is operatively connected with the shaft 34 of the cable conveyer 22 and with the elevating sprocket chains 47. 1

The duplex arrangement of the sprocket gears 47 for supporting the hanger shaft 48 is provided to hold the hangers 46 in proper operating position for engaging with the pallets, as without this provision the .hangers would be liable to tiltfrom the proper positionand thus prevent proper operation. The shaft 30 for the inner end of the shed conveyer 21 may be providedwith guide ways-58 for engaging with the ends thereof to hold them in proper alinement and to prevent obstructing the operation of the adjacent parts.

The upper shaft 53, as shown, is surrounded by a sleeve 59 that rotates with the brick yards comprising in combination a shed conveyer for delivering. loaded pallets for setting and a second conveyer for returning unloaded pallets, a yard conveyer, and means for delivering loaded pallets from the said yard conveyer to the said shed conveyer. I

2. Elevator and conveyer apparatus as described in claim 1, and the said second conveyer being in the'form of a positively driven cable conveyer. 1

3. In elevator and conveyer apparatus for of a pallet each' individual hanger being supported by the end of a relatively short shaft, and the said sprocket chains being arranged in two pairs with both members of a the said shaft.
