The "Big Boy" Litter Carrier 



( PATENTED ) 



SPECIFICATIONS 



TUB: Constructed of eighteen-gauge galvanized sheet steel, built on a framework of 

 angle iron; angle iron at side edges being I !/2xl j/^x' a in- ; at the ends ?/8xl |^x' k 

 in. ; end of tub reinforced with steel plate 4I/2x' a in. Well riveted, all ri\e[s 

 sherardized and are ,''t in., except corner rivets, which are ' 4 in. Gudgeon support 

 IS riveted to the two thicknesses of steel on end of tub. Tub is self-cleaning. For 

 complete information see page 187. 



PERFECT CONTROL CLUTCH AND BRAKE: Of malleable and bar steel. 

 For explanation of operation see page 1 89. 



HOIST: Chain and sprocket type. Made of best iron and steel. The frame carrying 

 the lower sprocket is adjustable to take up the slack, thus making it possible to over- 

 come any wear. So geared as to make possible the raising of heavy loads in the 

 shortest time without undue effort. (See page 189.) 



CHAIN GUIDES: Malleable. Prevent hand chain running off the hoist wheel. 



SHAFT: Of 1 !/4-in. cold rolled solid steel shafting, same as used in factories for line 

 shafting. (Page 193.) 



LIFTING CHAIN: Heavy straight link chain, tested for live times the load it will 

 have to carry. Three point suspension: in winding up forms an open spiral, prevent- 

 ing rubbing and wear. (Page 193.) 

 The distance from the top of the tracker wheels to the bottom of the Big Boy No. 2 

 Tub when raised is 43 inches; when lowered to full length of lifting chain the distance 

 IS 8 feet 8 inches. 



TRACKER WHEELS: Made of gray iron; 4f4 in. in diameter, mounted in swiveled 

 tracker wheel frames. Travelers arranged tandem. Tracker wheel axle of steel 

 with oil pocket; journal machined and surfaced. (See pages 188-189.) 



TRACKER WHEEL FRAME: So constructed that wheels cannot jump the track. 

 May be removed only by hand. (Pages 188-189.) 



LATCH AND TRIP: Latches at each end of tub lock and unlock simultaneously. 

 Protected against clogging with manure. Latch trip operated from either end. 



BAIL HANGERS: Heavy flat steel bars /;; x 1 '^ in., edgewise to the tub. Mal- 

 leable fittings and sheave. (See page 187.) 



BEARINGS: All bearings that get wear in operation are machined to assure accurate 

 fit and smooth surface; this reduces friction, lessens wear, increases ease of operation 

 and adds greatly to life of carrier. Bearings that are left merely cored, as they 

 come from the foundry, are covered with sand roughness, which cuts into metal 

 like so much emery. Hence the great importance ol machined bearings. (See 

 page 196.) 



CAPACITY: Tub No. 2 is 45 in. long, 24 in. deep, 24 in. wide, and holds approxi- 

 mately I 2 bushels coarse manure. 



WEIGHT: Tub No. 2 approximately 200 pounds.
