DISK-SLED ATTACHMENT.

Specification of Letters Patent.

Patented Nov. 9, 1915.

Application led 'February 7, 1914. Serial N o. 817,205.

To all whom t may concern:

Be it known that I, LAMY A. GAUME, a citizen of the United States, and a resident of Danville, in the county of Harper and State of Kansas, have invented certain new and useful Improvements inl Disk-Sled Attachments, of which the following is a specification, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in disk sleds and comprises an automatic attachment by means of which the soil, in the use of the disk sled, is cross harrowed, the furrows made by the disks beingy immediately closed while the ground is leveled, thus conserving the moisture, while eliminating the furrows.

Another object is to provide a disk sled with a time and labor saving attachment, that can be readily secured to al disk sled, expediting the working of corn, Kafir, cane, cow peas, or any other listed work.

IVith these and other objects in view, the present invention consists in the combina tion and arrangement of parts as will be hereinafter more fully described and finally pointed out in the appended claims, it being further understood that changes in the specie structure shown and described may be made within the scope of the claims, without departing from the spirit of the invention.

In the accompanying drawings forming a part of this specification, and in which like numerals of reference indicate similar parts in the several views: Figure 1 shows a side elevation of a disk sled provided with my attachment, the leveling knives being shown eut of working position in dotted lines. Fig. 2 is a top view of Fig. 1. Fig. 3 is a side elevational view showing the tension lever thrown into working position. Fig. 4: is a view showing in detail one set of knives and their connections, a broken portion of the rock shaft also being shown. Fig. 5 shows an enlarged sectional detail of the two part tension spring. Fig. 6 shows a broken detaildisclosing the members securing the tension leverI to the tension bar. Fig. 7 shows a broken detached detail of one of the bearing ears and collars.

In my present invention I provide an automatic disk sled attachment, comprising'a set of spring held drag knives,.the position of which can be accurately adjusted and which are carried by a holder the tension of which can also be adjusted land regulated so that where a field is worked comprising a dry, tough, cloddy heavy gumbo soil, the

knives are held more stiii'iy than where used in light, mellow, moist loose or sandy soil.-

The knives operate to level the soil immediately after the passage ofthedisks so that there is no loss of moisture, and this leveling of the soil prevents washouts and the packing of the soil through rain.

In the drawingsthe numerals 1, 1 represent two suitable sled runners to the forward ends of which aresecured the side bars 2, 2 by means of the bolts 3. Secured near the rear end to each runner 1 by means of a bolt l are the ends of the U-shaped frame 5 this frame being further braced by means of the bracebars 6 secured by means of the bolts 7 and 8. A seat is fixed to this frame 5. i

As shown in Fig. 3, each side bar 2 is provided with a U-shaped shackle 9, suitably secured thereto, and held upon the upper edge of each bar 2, by means of a shackle 9 is a disk shaft 10, provided with suitable cutting disks 11. At their inner ends these disk shafts 10 are connected to a bolt a, from which extendsthe connecting rod 12.

HeldA upon the upper edges of the side bars 2 is the cross bar 13 which is secured by means of thefclipsflt-which engage the bars 2,'as shown n F igs.; 1 and 3; Secured to this cross bar 13, is a gear sector 15 carrying a pivot pin 16 giving support'to the operating lever 17 which is connected by means of the pin 13 to the connecting rod 12. By meansof this lever 17 the disks 11 are adjusted. This-lever, 17 is provided with a suitable detent as is .usual in lever construction, the detent being arranged for co-action with the gear sector 15. Further secured t0 the cross bar 13 is the gear sector 20 to which is operatively connected the adjusting lever 21 having a suitable'detent or thumb latch arranged for co-action with the'gear sector 20. To this adjusting lever 21 is secured the connecting rod 22 which. has its upper ends suitably secured to the U-shaped frame 5. Secured to this cross barrl3ris the s draw bar 23 carrying a suitable ring o, at

its end to which the draft animals are connected.

Secured to each ofthe side bars 2 byl end having a slotted head 26. This standard is braced by means of the rod 27 secured by means of the bolt 2S to the upwardly curved end of the side bar 2, as clearly shown in Figs. l and 3. Secured to the rear upstanding end of each side bar 2 by means of a bolt 23 is a counter-part carrying bar 30 each having one end slightly curved as is shown in Figs. 1 and 3. At their forward ends these carrying bars 30 are secured by means of bolts 77., to the standards 25, 25. At its rear end each carrying bar 30 has secured to it a bearing ear 3l one of said ears being shown in detail in Fig. 7, and these bearing ears are arranged to revolnbly receive the bearing collars 2, each having a stop shoulder 3, and a setbolt 3. Securely held within these bearing collars `2 is a square rock shaft 32 to which are secured in parallel spaced relation, but in staggered position the trailing knives'A, A and B, B. As shown in Fig. 2 one of the carrying bars is secured to the end of the opposite side bar 2, by means of a connecting rod f.

As shown the knives A and A which are po sitioned below the knives B, B are shorter than the knives B and B', all of said knives being curved, the knives A and B curving in a direction. however opposite the knives A and B, as shown in Fig. 2. IThese knives are adjustably secured to the rock shaft. The knives A and A are each secured to an offset knife holder 34 shown in detail in Fig. 4, and within the socket 35 of each holder the knives are held by means of suitable bolts and nuts and (3. These bolts pass through suitable slots c, within both the holder and the knife, so that these knives are adjustably secured to their holder. Each holder 34 has a head 36 having a square opening to receive the shaft 32, the holders being secured by means of set bolts 3. Held in spaced relation to the offset holders 34 are the holders 37 having the sockets 33 within which are held the slotted ends of the knives B, the bolts 5 land nuts G being used to adjustably hold these knives B to the holders 37 which are also provided with slots fu, as shown in Fig.v 4. The knives A and B curve in. one direction, while the knives B and A curve in opposite directions, the two longer knives B, B being held adjacent one another.

Secured zto the rock kshaft 32 is a crank arm 33 which is held to the rock shaft 32 by means of a set screw 3 and this arm 33 at its upper end carries a bolt 7 as shown in Figs. l and 3, and this bolt in turn gives pivotal. support to the apertured tension lever 40 which is adjustably secured to the bolt 7. Near what forms its inner end the bar 40 is provided with a stop head 41 having the lip e, which is arranged to engage over the connected tension bar 43, the head 4l having an operating handle 42 as clearly shown in Fig. 6. The tension bar 43 is pivotally secured to the lever 40 by means of the bolt 8 and this tension bar 43 at its forward end is provided with a slotted socket 44, within which is held a two part spring comprising the intertwining coils 53 and 54.l

slot of the head 26 is a bolt 59 which passes through the lever 50 and gives'support to a Wingnut 51, so that bymeans of this bolt 59 and nut 5l the set lever 50 can be locked to the standard 25 in regulating the tension of the members 46, l43 and 40. The length of the springs 53 and 54 can be adjusted in screwing or unscrewing the members 53 andl 54 toward or away from one another, thus regulating the tension of the spring.

In going to or from a field, the tension lever 40 is thrown out of engagement with the tension bar 43, thus permitting the knives being thrown upward into a vertical position, as shown in dotted lines in Fig. l.

As shown the attachment is simple and inexpensive in construction, and both durable and efficient in operation, and the tension of the knives may be regulated with ease, accuracy and despatch to meet the condition of the soil.

Having thus described my said invention what I claim as new and desire to secure by S. Letters Patent is:
