CULTIVATOR.

SPECIFICATION 'forming part of Letters Patent No. 369,951, dated September 13, 1887.

Application filed April 15, 1887.

T0 all whom it may concern:

Be it known that I, PHINEAS P. MAST, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Cultivators, of which the following is a specification, .reference being had therein to the accompanying drawings.

This invention relates to improvements in cultivators, and it has particular reference to that class in which a cross -head carrying shovel-standards is used and held parallel to the axle by an alignment-rod.

Letters Patent were granted to me December 21, 1886, and numbered 354,717, and April 19, 1887, and numbered 361,307, for improve ments in cultivators in which the cross-heads are so fitted to the beams or beam-brackets as to overcome the twisting tendency between them and carry two shovel-standards- The present invention is designed as an improvement upon them-noa however', in the sense of bettering their construction, but rather in the sense of modifying some of the features there shown and described and adapting them to another style of machine, and in the further sense of making certain additions necessary in this latter style of machine, but not applicable to the former class.

With these ends in view the invention consists, first, of the cross-head constructed with special reference to being pivot-ally connected to a cultivator-beam and having three distinct parts or places fashioned to allow of the connection therewith of as many shovelstandards.

Secondly, theinvention consists, essentially, of the cross-head so constructed, when combined with the beam or beam-bracket (these terms being synonymous in this specification, because the beam-bracket may be a part of the beam or may be separately made and attached to it) having a portion to which the handle can be secured, and so located as that the third shovel-standard will not be obstructed when the relative position of the bracket and crosshead is changed; and, thirdly, the invention consists of the crosshead having enlarged upper and lower bearing-surfaces, and a wall to which the third shovel-standard is secured, and located in the rear of said surfaces, and the beam-bracket having a jaw fashioned with Serial No. 234,871. (No model.)

corresponding enlarged bearing-surfaces and partially encircling the crosshead, the open end of the jaw allowing the wall or third standard to move laterally.

In the accompanying drawings, forming a part of this spccication, and on which like reference-letters `indicate corresponding parts, Figure 1 represents a plan view of a portion of a cultivator, showing my improved crosshead and beam or beam-bracket; Fig. 2, a vertical transverse sectional view of the crosshead and beam-bracket, the latter being partially shown in side elevation, and a portion of the intermediate or third shovel-standard in like elevation; Fig. 3, an enlarged detail side view of the crosshead, beam-bracket, and adjacent parts; and Fig. 4, a rear view of the cross-head, showing portions of the standards attached thereto.

The letter A designates a portion of the axle of any approved cultivator, and the letter B the sleeve, and the letter C the collar, adjustably mounted thereon and having the vertical hub and lateral arm to which the beam D and the alignment-rod E are respectively connected, as shown and described in my Letters Patent first above named.

It should be noted that any other Vform of connection than that here alluded to of the beam and alignment-rod to the axle may be employed, though this is the preferred form.

The letter F designates the rear end of the beam or the beam-bracket itself, and it cousists'of a metallic frame, when a bracket, (a malleable-iron I`rame,) and is provided with a jaw composed of upper and lower bearing portions or surfaces G, having holes for the reception ofa king or coupling bolt, H. 'It is further provided with flanges or standards I and J, having, respectively, a bolt-hole and an irregular slot for the reception of bolts K and L to secure the handle M, the said standards being connected and strengthened by an intervening web, N. The disposition ot' the standards I` and J upon the bracket is such as to give the handle the proper direction laterally.

It will be observed that the rear ends of the jaws are disconnected. It will also be observed that the connection ol' the handle to' the beam or beam-bracket is above and en- IOO tirely clear of the cross-head. The absence of any connection between the rear ends of the jaws and this arrangement of the handle allow of the connection ot' the intermediate shovelstandard with the cross-head at a point substantially coincident to the vlongitudinal vcenter of the beam, and between the upper and lower sides ofthe cross-head, without inter fering with the free lateral movement of said standard.

The letter O designates my improved crosshead, constructed of metal, preferably of malleable iron, and ofthe shell-like form suggested in Figs. 2 and 4. At either end the head is constructed'with seats, to which the shovelstandards are secured, and these seats arel either one vertical and the other horizontal or both horizontal or both vertical. The head is further provided with upper and enlarged bearing-surfaces, I), extended somewhat forward of the cross-head, as seen at Qin Fig. 2. l-Ioles are provided for the passage of the king or coupling bolt already alluded to. The t between the jaw and the surfaces P is smooth and snug, and thereby, together' with the fact that the surfaces are enlarged, all twisting between the cross-head and the beam-bracket is prevented, as explained in the patents to which reference has been made.

The letter S designates a wall occupying the interior of the cross-head and projecting slightly rearwardly, and constructed to form a seat, as seen in Fig. 2, to which is fitted the third orintermediate shovel-standard, T. The head is further provided with a lug, T', to which the align ment-rod E connects at its rear end. The operation or joint action of the alignment-rod and beam in respect to maintaining the parallelism between the cross-beam and the axle of the machine is as usual. The outer shovel-standards are bent or deflected outward, as seen in Fig. 4, for the purpose of bringing the shovels the proper distance apart without unduly lengthening the cross-head.

It is obvious that the position of the intermediate standard on the crosshead may be varied from that shown and described without departing from this invention, though that position is the preferred one, as it brings the draft on aline with the beam and within the length of the coupling or king bolt, as already suggested. The seats into which the shovel-standards are fitted and secured may of course also be varied in form, as many ways of connecting the standards will readily present themselves to those familiar with this branch of manufacture. l

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

1. In a cultivator, the combination, with a beam or beam -bracket having portions to which the handle may be secured and constructed with a part adapted to engage with a cross-head, of the cross-head constructed with a matching part and having seats for two outer and an intermediate shovelstandard, and standards and their shovels for said seats.

2. In a cultivator, the combination, with a beam or beam-bracket having handle portions,

of a cross-head pivoted to the beam or beam.

bracket in a different plane from that of the handle portions and having seats for two outer shovel-standards and an intermediate shovelstandard, and shovel standards and their shovels for said seats.

3. In a-cultivator, the combination, with a beam or beam-bracket having handle portions,

side and beyond the jaw.

5. In a cultivator, the combination, with a beam or beam-bracket, of a cross-head pivoted thereto and constructed with two outer shovel standard seats and an intermediate shovelstandard seat, and shovels having .standards secured to said seats.

6. In acultivator, the combination, with the beam or beam-bracket having handle-standards and a jaw whose upperand lower members are enlarged to form bearing-surfaces, of a cross-head whose upper and lower portions are also enlarged to form bearing-surfaces,piv otally mounted in said head, and having outer shovel-standard seats, and an intermediate shovel-standard seat located between the'said upper and lower portions.

.7. In a cultivator, a cross-head having a king-bolt hole and two outer shovel-standard seats,and an intermediate shovel-standard seat located between the upperand lower portions of the head and substantially in line with the said hole.

8. In a cultivator, a beam or beam-bracket formed into a jaw at its rear end, the upper and lower members of which are enlarged to form bearing-surfaces and have a king-bolt hole and handle-standards projecting from the upper member. y

In testimony whereof I aflix my signature in presence of two witnesses.
