STLECIFICATION forming part of Letters Patent No. 412,106, dated October 1, 1889.
Application filed January 9, 1889. Serial No. 295,827. (No model.)
To @ZZ whom t may concern: I is the guiding-handle iixed rigidly to the Be it known that I, AUGUST LINDGREN, ot' plate E on the rear end of the beam. Moline, in the county of Rock Island and In their general construction andvmode of State of Illinois, have invented certain Imoperation the foregoing parts are similar to 5 proVement-s in Cultivators, of which the folthose in other machines of this class, the piv- 55 lowing is a specification. otal connection of the cross-head and the con- This invention relates to that class of cultrolling effect of the rod serving to hold the tivators in which thelaterally-swinging beams cross-head at all times parallel with the axis, carry at their rear ends vertically-pivoted although it is permitted to nieve laterally Io cross-heads to which the shovel-standardsaie with the beam. 60 attached, the cross-heads being kept parallel The present improvement relates solely to with the axle by controlling-rods, so that the the manner of constructing and uniting the shovels face constantly in one direction. It cross-head and the plate F. Thecross-head pertains more particularly to those machines is formed, as shown in Figs. l, 2, and 4, with l5 in which the cross-head is provided with a a large central opening therethrough from 65 central opening from front to rear for the front to'rear, and with seats or bearings f passage of the beam therethrough, as shown, f f2 to receive the shovel-standards which for example, in Letters Patent of Vvagner, Will be bolted firmly thereto. Midway of its July 13, 1879, No.2l7 ,914. Its aim is to render length the cross-head is provided at the top 2o the pivotal connection between the beam and and bottom with vertical holes 'nato permit the 7o cross-head strong, simple, and compact in passage of a vertical pivot-bolt J. A conical form, to relieve the pivot-bolt from Wear and pivot or stud c, encircling the pivot-hole m, strain, and to avoid the use of enlarged or projects upward into the central opening of expanded bearin g-surfaces between the parts. the cross-head. Directly over this pivot, at e 5 In the accompanying drawings, Figure 1 is the top of the crcsshead, a seat or recess h is 7 5 a vertical axial section through my device formed in the front edge of the cross-head. from front to rear. Fig. '2 is a perspective This seat is of semicircularformin horizontal view of the cross-l1ead,looking in an upward section, and extends from the front edge of direction from the forward side. Fig. 3 is a the cross-head backward therein, its Walls be 3o perspective view of the plate or arm which is ing concentric Wi th the vertical pivot-hole. 8o attached .to or formed upon the rear end of The arm F is shaped at one end to receive .the beam or drag-bar. Fig. e is a front view the handle and at the opposite end to admit of the cross-head. Fig. 5 is a plan view IshoW- of its being riveted or bolted t-o the beam, and ing in outline one side of a cultivator, illusis made of suitable size to permit its passage 5 trating the manner in which the improved through the cross-head from front to rear. 85 devices are used. It is formed in the lower edge with a conical Referring to thedrawings,A represents the seat k, adapted to receive the pivot-stud g, axle of the machine; B,'one of the ground- 'and is formed at the top with an upright cywheels by which it is sustained; C, one ofthe lindrical journal l, adapted to lit snugly Within fic drag-bars or beams connected to the axle by the seat or cavity 7i. rlhe arm is inserted by 9o a coupling D, of any ordinary or approved passing it endwise through the head, then form, whereby the rear end of the beam is seating the pivot g Within the cavity k, and permitted to swing laterally and vertically. thereafter slipping the journal l into its seat E represents the cross-head carrying the h, after which the vertical bolt J is passed 45 Shovel-standards G, and pivoted to a plateF, upward through the top and bottom of the 95 fixed rigidly to the rear end of the beam. cross-head and through the intermediate arm,
H is a so-called parallel rod lying alongas shown. Side the beam, with the rear end jointed to It Will be observed that under my constructhe cross-head and the forward end jointed tion the Wearing-surfaces are all made of 5c to the coupling or the axle. small size, and that there are no hubs, disks, roo
or other enlargements required. Inasmuch as the strain exerted upon the shovelstend's to tip the lower side ofV the cross-head E backward and the upper side forward, as indicated by the arrows in Fig. 1, it will be Seen that the entire strain and Wear are taken in my contrivance at the bottom by the pivot g and at the top by the bearing h, seated behind the journal Z, the pivot-bolt being practically free from strain and wear. the pivot-bolt need not be relied upon in the least to support the cross-head when in action, the form of the parts and the direction of the strains being such that although the bolt J may be wholly removed the cross-head will be sustained in operative position, the bolt serving mainly to prevent the accidental separation 0f the parts in transporting or packing the machine.
rlhe principal distinguishing feature of my construction lies in the formation of the crosshead to carry the shovels and the beam-plate with the rigid Qomplmentary bearings atthe terlock and resist the tendency lof the crosshead to roll forward under the strain of the shovels, so that the cross-head and shovels are held in operative position without reliance upon the pivot-bolt.
I believe myself to be the first to construct the cross-head and the beam-plate with rigid interlocking pivot-beari,ngsl at the top and bottoni of such character that the parts will remain in operative position although the pivot-bolt may be removed.
In fact, p
In practice it is sometimes desirable to provide the cult-ivator with six shovelsthree for each beam. In order to permit the application of the two additional shovels, I propose to provide each cross-head on the under side with a socket to receive the end of a third shovel-standard, or tootherwise form thecrosshead to permit of the third standard being bolted thereto.
Having thus described my invention, what I claim isl 1. In a cultivator, and in combination with the cross-head having the shovel-standards attached and the fore-and-aft opening therethrough, the beam-plate formed with upper and lower pivot-bearings, substantially as described, adapted to interlock with the crosshead, the upper bearing to resist forward and the lower bearing to resist backward motion of the cross-head, whereby the beam-plate is enabled to 110,111 the cross-head and shovels in operative position without reliance upon a pivot-bolt to receive the strains; top and bottom, the bearings adapted to in- In a Clllivatona cross-head provided with aA pivot-stud and a seator cavity, in combination with ,a beam-plate provided with a cavity to receive the stud and with a journal to enter the seat.
In testimony whereof I hereunto set my hand, ,this 28th der 0f November, 1888, in the presence of two attcsting witnesses.
