The "Big Boy" Litter Carrier 



PATENTED) 



Specifications 



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

 angle non ; angle n'on at side edges being 1 ' 2 ^ I ' 2 ^ ' 8 in. : at the ends ^/g x I ^ g 

 X ' g in. ; end oi tub reinlorced with steel plale 41 2 " ' » ""i- Well riveted, all 

 ri\ets sherardized and are ,',. m., except corner rivets, which are ',4 in. Gudgeon 

 support IS meted to the two thicknesses ol steel on end of tub. Tiie tub is sell- 

 cleaning. For complete information see page 229. 



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

 For explanation of operation see page 231. 



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

 the lo\ver 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 231.) 



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



SHAFT: Of I ' 4-in. cold rolled solid steel shafting, same as used in factories for line 

 shafting. (Page 235.) 



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

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

 ing rubbing and wear. (Page 235.) 



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

 Tub when raised is 44 inches; when lowered to full length of lifting chain the 

 distance is 8 feet 8 inches. 



TRACKER WHEELS; Made of gray iron: 4^4 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 232-233.) 



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

 May be removed only by hand. (Page 232-233.) 



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

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



BAIL HANGERS: Hea\y flat steel bars -fV x I I/2 i"-. edgewise to the tub. Mal- 

 leable fittings and sheave. (See page 229.) 



BEARINGS; All bearings that get much 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 of machined bearings. (See 

 page 228.) 



CAPACITY': Tub is 45 m. long, 24 in. deep, 24 in. \vide, and holds approxi- 

 mately I 2 bushels coarse manure. 



WEIGHT; Approximatelv 20(1 pounds.
