DRAFT-EQUALIZER.

' Specification of Letters Patent.

. Patented Nov. 13, 1906.

Application filed July 13, 1905. Serial No. 269,532.

. 'IIDPI'OVG the construction of draft-equalizers and to provide a slmple, inexpensive, and eflicient one of great strength and durability designed particularly for use on cultivators' and adapted to equalize the draft between three horses.

With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fullydescribed, illustrated in the accompanyingdrawings, and pointed out in the claims hereto appended, it being understood that various changes in the form, pro-1 portion,- size, and minor details of construction within the scope of the claims may be resorted to without departing from the spiritl or sacrificing any of the advantages ofthe in-- vention.

In the drawings, Figure 1 is a plan view of a draft-equalizer constructed in accordance with this invention. Fig. 2 is a front elevation of the same, the draft beams or tongues being in section. Fig. 3 is a vertical sectional view taken substantially on the line 3 3 of Fig. 1. Fig. 4 is a similar view taken substantially on the line 4 4 of Fig. 1.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates an axletree forming a portion of the frame of a cultivator and secured to the rear portion of a pair of longitudinal draft beams or tongues 2, which are connected in advance of the axletree by means of a transverse bar 3, preferably constructed of flanged metal, such as angle-iron, as clearly shown in Figs. 3 and 4 of the drawings. The transverse bar, which extends laterally from the draft beams or tongues, forms a support from which is hung central and side upright oscillatory levers 4 and 5, fulcrumed at their upper ends and having their lower ends carrying swingletrees 6 and 7. The upright oscillatory levers are forked and are pivoted to the transverse bar by means of brackets or hangers 8 and 9, having horibrace.

zontal pivots or pintles, which are arranged in perforations of the levers 4 and 5. The sides 10 of the fork of the central lever 4 diverge and are inclined, as shown, and the horizontal pintles or pivots extend into perforations or openings of the sides 10 from the outer faces of the latter, whereby the central lever will be securely retained in position when the brackets or hangers 8 are secured to the transverse bar 3. The outer side of the fork of the outer levers is vertical and forms a continuation of and is arranged in the same plane as the lower portion of the outer levers. The inner side 11 .of the fork of the outer levers is inclined and forms a the end brackets 9 are shown extending into the openings of the outer'levers from the inner side of the same, and'keys 12 or other suitable fastening devices may be provided The horizontal pivots or pintles of for retaining thelevers onthe pivots or.

pintles; but the brackets at the outer levers may be arranged like those of the central bracket. employed for hinging the upper ends of the levers to the supporting transverse bar. The whiffletrees 6 and 7 are pivotallyconnected with the lower ends of the upright levers by means of links 13, which may be of any desired construction. 13i

Any other suitablemeans may be.

n f The central and side levers 4 and 5 are coni nected with a pair of transversely-disposed approximately horizontally arranged equalizing bars or levers 14, connected between their ends by links 15 with an axletree, preferably at the upper face thereof. 15 are pivoted at their rear ends to the axletree by means of bolts or other suitable fastening devices, and their front ends 16 are forked or bifurcated to receive the draftequalizing bars or levers, to which they are pivoted. The inner arms of the draft-eqaulizing bars or levers, which are twice the length of the outerarms, are connected with the central upright leve'r, which is provided at an intermediate point with'an inwardlyextending bracket 17, having a forked or bifurcated portion, in which is mounted a grooved pulley or wheel 18. The grooved pulley or wheel 18 receives a chain 19 or other suitable flexible connection, which has its terminals connected with the inner ends of the equalizing bars or levers by means of links 20. The links 20 consist of short rods provided at their terminals with eyes, the rear eyes being linked into eyebolts 21 and ed to move on'the pulley,

with the upright the front eyes being linked into the endsv of the chain 19. The eyebolts pierce the inner ends of the equalizing bars or levers and are provided with nuts, as shown. The outer ends of the equalizing bars or levers are provided with eyebolts 22 and are connected with the outer upright levers 5 by means of rods or links 23, which form stiff connections between the outer upright levers and the equali'zmg bars or levers. The links or'ro'ds' 23 are provided at their rear end with eyes to receive the eyebolts 22, and the front ends of thesaid links or rods 23 are pivoted to the lower ends of the outer u right levers,-as clearly indicated in Fig. .3 o the drawings.

The equalizing bars or leversare connected levers, and they are adapted to oscillate to equalize the draft between three draft-animals, and when the levers 1 4 oscillate the flexible connection 19 is adaptand the upright levers 4 and .5 are also adapted to oscillate toyield to the movement of the equalizing bars or levers.

The device is designed particularly for use on cultivators and, as shown, is adapted to equalize the draft between three horses or other draft-animals; but by substituting doubletrees for thesw-ingletrees the device may be advantageously employed for equalizing the *draft between siX horses. The equalizer may, however, be advantageously employed onma-chines other thancultival tors.

Having thus fully described my invention, what'lclaim as new, and desire to secure by Letters Patent, is-

1. The combination with a frame, ofa pair of transversely-disposed horizontally-swing ingequalizing-bars or levers fulcrumed at an intermediate point on the said frame to form inner and outer arms, central and outer upright levers depending from the frame, means for connecting the outer upright levers with l the outer arms of the horizontally-swinging equalizing bars or levers, a flexible. connection slidable on the central upright lever and i connected with the inner arms of the said equalizing bars or levers, and whiflletrees connected with the outer and central upright levers.

2. In a device of the class described, the combination with a frame, of a pair of transl versely-disposed horizont ally-swinging equalizing bars .or=levers fulcrumed atan'intermediate point on the said frame to form innerand outeriarms, upright central and outer levers depending from the frame, means for 1 connecting the outer arms of the equalizing bars or lovers with the lowerends of the outer upright levers, a flexible connection slidably connected with the central upright lever at a point between the ends thereof, said flexible l connectionhaving its terminals connected with the inner arms of the saidequalizing 'bars or levers, and wvhiffletrees connected with the upright central and outer levers.

Ina device of the class described,-the combination of central and outer upright levers having forked upper portions forming braces, whiifletrees connected with the lower ortions of the levers, and equalizing bars or v evers connected with the said levers. 1 testimony thatl claim the foregoing as my own I havehereto a'ffiXed mysignature in the presence of two. witnesses.
