SPECIFICATION forming pari, of Letters Patent No. 657,494, dated sltnber 4, 1900. Application filed J'uly 26, 1900( Serial No. 24,902. *(No model.)

T @ZZ whom, it may concern,.-

Beit known that I, JOHN J. MARICK, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Plows; and Ido declare the following to be a full, clear, Vand exact de.

such mannerastobe readily and con veniently assembled and disassembled for repairs or other purposes, to provide means affording au wide range of adjustment of the working parts, and to generally simplify and improve i the constructionvand increase the practical efficiency of plows of this character.

In the accompanying drawings, Figure 1 is a perspective View of a gang-plow embodying my invention. Fig. 2 is a side elevation thereof, showing the inner end of the tongue in section. Fig. 3 is-a cross-section through the front truck-frame of the carrying-wheels and cooperating parts looking toward the front and showing in dotted lines the wheels reversed to widen the gage in transporting Fig. 4 is a vergles to that shown in Fig. 3. Fig. 5 is a detail perspective view of the draft-collar and one of the draft-rods. Fig. 6 shows two inner side elevational views, representing the cut,- ter 4 and shield-plate 4-. perspective view of one of the cuffs for holding the draft-rods in place. Fig. 8 is a similar view of one of the pins for securing theV cross-beam. Fig. 9 is a detail View of one of Athe keys for securing the wheel shaftsor axles. Fig. 10 is a perspective view of-the head-tube, draft-arm, and washer and top is a perspective view of vthe rear diagonal Fig. 7 is a detaill cross-beam. Fig. 14 is a detail view of the rear bearing-plate for the caster-wheel, and Fig. 15 is a fragmentary rear perspective view of one of the plows.

Referring now more particularly to the drawings, in which like reference characters designate corresponding parts throughout the several views, 1 and 1fL represent two hollow or tubular beams resilient formed or provided at their rearends with tubular stocks or standards 2 and 2, which carry the plowshares 3 and moldboards 3a. Each standard is recessed upon its inner side to receive a cutting-blade 4, which is bolted or otherwise fastened thereto. When this blade is not used, a shield-plate 4a is inserted in its place in the recess to prevent the entrance of dirt and to protect the walls of the recess from injury. One of the beams is made shorter than the other to provide for the proper mounting of the plows one in advance of the other in the usual way, and the two beams are connected at their rear ends by a diagonal .cross-beam 5, formed of spring metal and provided with a central opening 6 and. tubular legs 7 at the ends thereof, which legs are preferably formed bybending or coiling the metal upon itself and are adapted to fit down in the sockets of the standards 2 and 2,` One of these legs 7 is notched, as shown at 7, toreceive the angularly-bent end 8 of a removable bearing-plate 8. This Vend 8a is formed with a tubular slide 8b, which fits within the `upper end of the leg 7, having the notch 7,

while the opposite end of the plate is formed into a hub or tubular bearing 8c, in which is mounted the spindle 9 of the caster-wheel 10, which supports the rear end of the plow. The standards 2 and 2 are notched at their heel ends, as shown in Fig. l5, tor receive locking-bolts 11, having lower hooked ends 12 to engage the edges of the standards and upper threaded ends to receive nuts 13. These bolts pass upwardly through the sockets of the standards and legs-7 ot' the crossbeam 5 and'secure the rear ends of the side beams-l and l thereto, and in addition the bolt in the standard 1 also passes through the slide 8b and holds the hearing-plate S against displacement. By removing these bolts the rear cross-beam, bearing-plate, and

moved, if desired. AbraceV 14 is also detach.- ablyconnected vto the standard 2 by its bol't` 11 andis provided at its opposite end witha loop or eye 15, which engages the spindle 9 of the caster-wheel 10 and assists in holding the parts securely connected. Therear end of the frame is adjusted through the medium of a lever 16, pivoted nearits front end to a bracket 17, having an eye 18 engaging the said spindle of the caster-wheel. The forward end or short arm of this lever is connected to an 'arin V19 upon the bearing-plate 8 and carries a pivoted rack 20, normally held pressed into engagement with a hook or iixed pawl 2l on thebrace 14 by a spring 22. Upon pressing down the long arm-of the lever the arin 19 is forced upwardly, lifting the rear ends of the side beams in almanner lreadily understood, the loops or eyes or bearing portions 8b and 18 of Vthe bearing-plate 8 and bracket 17 sliding freely on the caster-wheel spindle during this movement. By thus adjusting the rear end of the frame the heel ends of .the plowshares may be elevated as desired. In transporting the plow from place to place it is desirable to provide a brake to Aprevent the plow from running upon the horses in descending grades. T0 this end I providea skid or shoe 23, carrying a link or chain 24 at its front end tov engage a hook 25, supported by a bracket 26 in the base of the This skid is adapted to 'support the caster-wheel. lO-and to act as a shoe or runnerand is provided with side flanges 27 to hold. it in engagement with the wheel. The drivers seat 28 is mounted upon a seatpost 28, having aslot 28. A key 28d, held by a chain 28", is provi-ded to fit into said slot to hold the seat-post secured. This key has a bit or lug, vand when inserted is given a quarter-turn to cause said bit t0 bridge across the slot and prevent withdrawal of the key. When it is desired to use the skid, it; is connected upto the hook 25 and placed under the caster-wheel 10.- The weight lof the driver, as well as that of the rear portion l ofthe machine, is thus thrown upon the skid',

vwhich is thereby caused to drag and-act as a brake to prevent the plow from moving forward too rapidly upon the horses. Therackbar l2O is adapted to be retracted and disengaged from paw] 21 through the medium of ai` rod, cord, chain, or cable 28L and a pivoted'y handle 29, connected 'thereto and mounted on the leverl, y f l The side beams V1 and 1a are connected attheir front ends by afront cross-beam 30, having openings at its ends, through which the. side beams pass and are supported by carrier wheels 3l and 32. These wheels are mounted upon hubs 33, providedY at their outer ends with diametrically-opposit'e openings 34 and at their inner ends with sand col-- l is rigidly-connected thereto to rotate therewithby means-.of a key 39, passed. through the Openings 34 and a corresponding opening in the outer end of the axle, as clearly shown in Fig. 3. The axles are longer than the hubs and project beyondA the inner ends of the saine land are journaled to rot-ate in a boxing40,

removably mounted upon the interior of a bearingsleeve 41,so as to be easily and conveniently removed when worn for substitution of va new boxing. The axles are formed "at their ninner abutting ends with annularl grooves 42 in. line with a slot 43 in the boxing, through which slot pass retaining-keys 44, having segmental notches 45 to fit within said grooves in the axles to hold both the boxing 'and axles inplace againstendwise movement. These keys are fitted within a rectangular box or socket 46, projecting upwardly from the center of the bearing-sleeve. In the normal operation ofv the plow when plowing the parts are arranged as shown in full lines in Figs. -fl and` 3, from which itwill be seen that the wheels 31' and 32 are located close up to the ends of the sleeve4l, with the sandbands 35 projecting over upon said ends of the sleeve to exclude dust, sand, and' dirt.

vIt is desirable, however, to widen the gage when the plow is being transported from one place to'another to obviate all liability of the rier-wheels as thus construct-ed and mounted are adapted to .swing upon a vertical stem yor king-bolt 47, projecting at its upper end IOS) IIO

`through a head-tube 48, carried by a draft V bar or arm 49. TheV lower end of the stem or king-bolt is made rectangular to fit within the socket 46 and is cut away or stepped to receive a chock-block or feather 50, having a y socket to receivethe bent end 51a of a locking-rod l51, extending parallell with the kingbolt and projecting through the -tube 48. This block when insertedhold's the kin g-bolt fi rmly seated in the socket 46'and when detached permits of the removal of the king-bolt through the head-tube 48. A bolt 503L secures the blockand lower end of the king-bolt in the socket 46. The bore or opening of the head-tube is key-,shaped to receive the kingbolt and rod and prevent independent rotative movement thereof, and said tube is provided fat ltop with threaded stems 52. A washer 53 iitsdown upon the top of the headtube, yand a cap 54 is litted thereon and pro- ;vded with a keyhole-slot 55 for passageof the A,king-bolt an-d rodN and openings 56 for passage of thestem's'52, on which nuts are threaded to hold the washer and cap in place.` The draft bar or arm 49 is provided with a central ange 57 and a lateral bracket 58, said flange being provided at its inner end with a slot 59. Passed th rough this slot is a collar 60, through the ends of which is passed a pivot-pin 61. To said pin are also pivoted a stirrup or yoke 62 and two draft-bars63, each of said draftrods consisting of a rod bent upon itself to form at one end a loop 64 and two parallel strands, provided at their free ends with eyes 65, embracing the ends of the collar 60 and pivotally mounted on the saidpin 61. These rods 63 extend rearwardly on opposite sides, and their loops 64 embrace the beams 1 and 1a and transmit the pull of the draft-animals eqn-ably thereto. An inverted-U -shaped coupling 62a is also mounted on the pin 61 and serves to prevent the yoke 62 and draft-rods 63 from spreading. The beams are each provided at their forward ends with two series of openings 66 and 67. The openings 66 are adapted to receive U-shaped pins 68, which hold the front cross-beam 30 in place, and the openings 67 the ends of similar pins 69, carried by cuffs 70, which act as stops to hold the loops 64 in place. The two sets of pins are connected by chains 71, and the cuffs are secured by chains 72 to a central channelbrace 73 to prevent loss or misplacement of the parts. lf desired, the pins 68 maybe retained in position by cutter-pins 74, passed therethrough. The channel-brace 73 is located centrally between the side beams 1 and 1a and has a downwardly-bent end 75 terminating in a flat foot 76, which is connected with the king-bolt 47 and locking-rod 51 and reinforces the same. The rear end of the brace terminates in a rod or arm 77, which is loosely mounted in the opening 6 of the rear crossbeam 5. To the channeled portion of the beam is pivoted a lever 78, the forward end of which is pivotally connected to the stirrup or yoke 62. ver the front ends of the side beams 1 and 1a may be elevated and depressed to move the plowshares up and down for deep or shallow plowing or for holding them above the surtace of the ground when the plow is being moved from one place to another. The rear end of the frame is elevated by the lever 16, as hereinbefore described. To hold the lever 78 fixed in adjusted position, a spring-actuated pawl 79 is provided to engage a rack 80, pivoted to the brace 73 and projecting through a slot 8l in said lever 78. This pawl is retracted by means of a pivoted handpiece 81 and a rod, cord, or wire 82, connecting same with the pawl. l i

The front cross-beam 30 is mounted to slide laterally in a fianged guide 83, carried by a sleeve 84, which is mounted on the head-tube 48 between a tiange 85 thereon and the cap 54. The upper dange 86 of this guide is made comparatively short to allow the side beams 1 and l to swing freely without interference, while the bottom flange 87 thereof is made By raising and lowering this lelonger to form an extended bearing. From the frontofthe cross-beam 30 projects an arm 88, to which is connected one end of a link or short lever 89. The opposite or outer end of this link is in turn connected to the forward end of a lever 90, pivoted near its front end to a bracket 91, projecting from the fixed sleeve 84 and carrying a segment-rack 92. The lever is mounted to swing laterally of the plow and rest upon a support 93 and is provided with a slot 93, through which the rack extends. A spring-pressed pawl 94 is provided on the lever to engage the rack and hold the lever fixed in adjusted position, and said pawl is operated by apivoted handpiece 95 and a rod or its equivalent 96. Byswiuging the lever in one direction or the other the cross-beam 30 will be slid in the guide to swing the side beams 1 and 1 and plows laterally to one side of the line of draft, so as to present a greater or less extent of surface of the plows and increase or diminish the size of the furrow.

The draft-bar 49 is provided at its front end with ears 97 for attachment of the tongue 98 and with a segmental slot 99 and a transverse opening 100. Adraftplate 101 is provided with a lip 102 to extend past the end of the fiange 57 of said bar and with a pivoted L- shaped key 103, the short arm of which is adapted to pass through an opening 104 therein and in the segment-al slot 99 and the long arm into the opening 100. In inserting the pin the plate 101 is held vertically with its lip 102 downward and the long end of the pin engaged with the opening 100. The plate is then turned down to an approximately-horizontal position to bring the short arm oi the pin into the slot 99, and inally swung forward on the pin until the lip 102 extends past the front end of flange 57. By this means the draft-plate is securely fastened against casual displacement. The outer rear edge of the plate has connected thereto a rod 105, which passes diagonallythrough a slot 105', formed in the fiange 57, and is connected to the bracket 58 in the opposite side of the draftbar. The purpose ofthis construction is to equalize the draft, the rod serving to transmit the pulling strain equally' to both sides of the draft-bar. The plate 101 is perforated to adjustably receive a elevis.

The cutters 4 are used for breaking land. Vhen it is not desired to use the cutters, a shield-plate 4LL is inserted in the recess in its place to fit snugly and prevent the walls of the recess from being broken or injured.

From the foregoing description, taken in connection with the accompanying drawings, the construction and mode of operation of the invention will be apparent, and it will be seen that it provides a gang-plow having desirable advantages, among them being the detachability of all the parts, so as to provide for ready repair and the quick replacement of a broken part, the effective raising and lowering of the frame, and the means whereby the IOO IIC

to the line of draft. Other advantages of the invention .will also be manifest.

It will of course be understood that changes in the form, proportion, and minordetails of construction may be made within the scope spirit or-.sacrificing anyl of the advantages thereof.
