 ing rims, standing at an angle of about forty-five degrees 

 from a vertical plane. The rims are held by arms radiating 

 obliquely from a central hull. A modification is shown and 

 descriVied in which the disks are adjustably mounted in 

 pails facin;,; inward, thus making a straddle row cultivator.

5.— In combination with the truck-wheels B B, frame A, 

 and ploughing-wheels H II, set diagonally to the line of 

 draft, the caster-wheel F. w ill, its flange/, all arranged to 

 operate substantially as descrilied. 



6.— The combination of tlie frame A C, having two sets 

 of axles, D Q, hook-bolts U, standard M, and keepers K, 

 adapted to receive rotary ploughs or cultivators, in the man- 

 ner described.

No. 171,092.— F. BRAMER, Little Falls, N. Y.— 

 VVheel-Harrmvs.— December 14, 1875.— [Filed October 6,

A series of disks placed in gangs upon two shafts, each 

 gang facing in opposite directions to prevent side draft. A 

 series of cleaners attached to a single bar for each gang, and 

 arranged to operate simultaneously by a lever. 



Claim. — In combination with a gang or series of rotating 

 harrow-disks, the clearers or scrapers united to a reciproca- 

 ting bar, adapting them to be operated simultaneously by 

 means of a lever, substantially as and for the purpose set

Claim. — I. — The combination, substantially as herein- 

 before set forth, of a series or gang of harrow-disks having 

 concave faces or sides with a series of scrapers or clearers 

 adapted to be vibrated or moved close to or in contact with 

 .said concave sides and removed therefrom while the machine 



2- — The combination, substantially as hereinbefore set 

 forth, of a series of rotating concavo-convex harrow- 

 disks, a series of pivoted, rocking, or adjustable clearers 

 or scrapers, connected together, and a lever pivoted on the 

 gang-frame, whereby the scrapers may be caused simul- 

 tancDuslv to apiiroach or recede from the concave faces of 

 the (l|,ks. 



3. —In onil.ination w^ith a gang or series of rotating har- 

 row-disks, the clearers or scrapers united to a reciprocating 

 bar, adapting them to be operated simultaneously by means 

 of a lever, substantially as and for the purposes set forth. 



4- — The combination, substantially as hereinbefore set 

 forth, of a draft frame, a gang or series of rotating harrow- 

 disks connected therewith, a scries nf scrapers united to a 

 bar mounted upon the gang ha r .! ^Ilvk frame and adapted 

 to vibrate in contact with or el.isc i.. tlie sides of the disks, 

 and a lever pivoted upon said gang Ijar, extending to within 

 reach of the driver while in hiCseat on the machine, where- 

 by the scrapers may simultaneously be caused to clear the 

 sides of the disks, and then removed therefrom when the 



disks are free and clear, to prevent clogging by accumula- 

 tion upon the scrapers.

Upon each side of the tongue is hinged a triangular frame, 

 the forward beam of which carries a gang of disk-teeth, 

 whose axis of rotation is placed oblique to the line of draft. 

 A seat for the operator is mounted upon a spring-bar, 

 whose ends rest in stirrups that are supported in brackets 

 rising from the rear beam of the triangular frame. 



Claim. — I. — The wheel-gang frames or planks, hinged 

 by their inner ends to the intermediate pole or tongue, or a 

 rigid extension thereof, substantially as described. 



2. — The gang-wheel frames, hinged to the intermediate 

 pole or pole-frame, in combination with the seat-support ex- 

 tending transversely over said pole or frame, and connected 

 with the gang-frames at points outside of the centres of their 

 transverse length, for the purpose and substantially as de- 

 scribed. 



3. — The transverse seat-support or bar connected with the 

 gang-frames by means of the swinging compensating links 

 or stirrups, substantially as described. 



4. — The combination, with the hinged wheel-gang frames 

 of the swivelling supports E, stirrups/, and transverse seat- 

 support or bar G, arranged and operating substantially as 

 described. 



5. — The combination of the hinged gang-frames A A', 

 intermediate pole or pole-frame B, swiveling standards E, 

 swinging stirrups/ and seat spring or bar G, all arranged 

 and oiKiating as described.

Claim. — I. — \\ heel-^angs hinged by their inner ends to 

 an intermediate pole or tongue, or to an extension thereof, 

 substantially as hereinbefore set forth, whereby they are en- 

 abled freely to conform to the surface over which they trav- 

 el. 



2. — The combination, substantially as hereinbefore set 

 forth, of independent wheel-gangs with an intermediate 

 pole or pole-frame, to which they are hinged at two points, 

 whereby they are braced against transverse strains, as well 

 as allowed freely to conform to undulations of the surface 

 over which they travel. 



3. — The combination, substantially as hereinbefore set 

 forth, of wheel gangs, an intermediate pole or pole-frame, 

 to which tlieir inner ends are directly hinged, and a trans- 

 verse ^cai-sui>pi)rt connected with the outer ends of the 

 gang-fianics, whereby the weight of the driver keeps the 

 gangs down to their work without interfering with their vi- 

 brations on their hinges. 



4. — A transverse seat-support connected with indepen- 

 dently-hinged wlieel-gangs by means of swinging compen- 

 satnig links or stirrups, substantially as hereinbefore set 

 forth, whereby the vertical movements of the gangs are 

 limited. 



5. — The combination, substantially as hereinbefore set 

 forth, of hinged wheel-gangs, swiveling socket-pieces mount- 

 ed on the gang-frames, and a transverse seat-support pivot- 

 ed to stirrups in the socket pieces, whereby Ijoth the verti- 

 cal movements and angular adjustments of the wheel-gangs 

 are compensated. 



6. — The wheel-harrow hereinbefore described, consisting 

 of the combination of wheel-gangs hinged to an intermediate 

 pole or pole-frame, swiveling socket-pieces mounted on the 

 gang pieces, planks, or frames, swinging stirrups pivoted in 

 said socket-pieces, and a transverse seat-support pivoted to
