PACKING AND MULSI-IING IMPLEMENT.

Specification of Letters Patent.

Patented Aug. 29, 1916.

To all whom it may concern:

Be it known that I, LAURITS T. RAsMUs- SEN, a citizen of the United States, residing at Council Bluffs, in the county of Pottawattamie and State of Iowa, have invented certain new and useful Improvements in Packing and Mulshing Implements, of which the following is a specification.

This invention relates to an improvement in packing and mulshing implements, and has for its principal object to provide such a mounting for the mulshing disks and packing wheels that, without increasing the draft, they may be disposed at greater or lesser altitudes, while revolving, for engaging the surface conformation of the ground, so that the ridges and hollow places as well as the level parts of a field may be reached by the wheels and disks.

The invention has reference to an implement provided with a flexible shaft on which the packing wheels and disks are supported closely side by side, said shaft being so mounted and supported that its parts may swing freely and automatically to be disposed upwardly-divergent from the middle of the vehicle while moving in the valleys, channels or grooves, and may swing readily and automatically to be disposed downwardly-divergent from the middle of the vehicle while moving upon and longitudinally of the ridges.

The invention also includes means for permitting a limited longitudinal movement of the flexible shaft, and means for a control for limiting such movement, and broadly consists of the novel construction, combination and arrangement of parts as described herein and claimed, and as illustrated in the drawing, wherein,'

Figures 1, 2 and 3 are rear views of the implement to illustrate the relative position of parts when moving in valleys as shown in Fig. 1, or upon ridges as shown in Fig. 2, or on level. ground as shown in Fig. 3. Fig. '-1 is a view of the implement in side elevation, the tongue being broken away. Fig. 5 is a view in longitudinal section through the tongue and frame. Fig. 6 is a partly broken end view showing normal positions, when in use, of the packing wheels and mulshing disks. Fig. 7 is a view, in side elevation, of one of the bearing-blocks for the flexible shaft. Flg. 8 1s a sectional view on line 8 8 of Fig. 7. Fig.

9 is a view in longitudinal section of a combined cylindrical bearing and ball mounting for connecting the inner ends of the flexible shaft. Fig. 10 is a section on line 10 10 of Fig. 6.

Referring to the drawing, numeral 11 indlcates an elongated frame consisting of the parallel strips va and Z), preferably constructed of angle iron, a pair of yokes or brackets 0 being provided and mounted upon the ends of said strips to project downwardly therefrom, each yoke or bracket being provided with a recess at opening on its lower end.

Numeral 12 indicates a tongue which is mounted upon the strips a and Z2, midway between the ends of the frame, and suitable inclined braces 13 and cross pieces 1 1 are provided to sustain the stresses directed to the frame and tongue, incident to the use of the implement, these being disposed and suitably secured upon the angle irons a and b.

Numerals 15 and 16 respectively indicate a pair of shafts having their inner ends flexibly connected by means of a cylindrical boxing 17, best shown in Fig. 9, each of their outer ends being mounted in a sleeve 18 of a bearing-block 19 disposed in a recess (Z and pivoted loosely at e to the arms 7 which project downwardly from the brackets 0 of the frame, whereby, the shafts may have free, lateral or vertical and rotatable movements with respect to each other while their inner ends are connected, and may have limited movements longitudinally in their hearings in the sleeves of blocks 19, subject to the king pins 20 which traverse the shafts at their ends while disposed in slots 8 of said sleeves.

At 21 is indicated a link disposed below the tongue, its front end being pivotally mounted at 22 in the bracket 23 which projects below and is supported by the tongue, its rear end providing a pivotal mounting or bearing for the inner end of shaft 16 adjacent to the ball 24 of said shaft, this bearing beingsubstantially at equal distances from the ends of the frame.

The operation of the link is such that the shafts, at their inner ends, may have swinging movements in a limited arc, the center of which is the pivot 22. Since this pivot is disposed forwardly of and at a considerable distance, comparatively, from the shafts, said shafts will be maintained subinner ends either upwardly ordownwardly through a considerable are.

Numerals and 26 respectively indicate packing wheels and .mulshing disks, each of .the packing wheels preferably having a taperedperiphery g as shown in the drawing, a clrcular bearmg-surface h on the 1nner side ofits tire and a hub 7a extending at one of its endsoutwardly of the plane of its tire; Each mulshing disk is preferably provided with peripheral teeth as indicated at vm, and with a transverse rim or flange n of lesser diameter than the circular bearing surface it of a packing wheel. The wheels and disks thus described are disposed in alternation to circumscribe the shafts, the packing wheels having bearings thereon with the ends of their hubs abutting upon each other. The mulshing disks are disposed with their transversely projecting rims or collars n disposed in the vertical plane and in engagement with a part of the circular bearing-surfaces h of the packing wheels. on account of the lesser diameters of the rims n of the mulshing disks as compared with the diameters of the bearing surfaces 72, of the packing wheels, their longitudinal axes willnot at all times be 00- incident with the axes of the packing wheels,

and when the implement is moving forwardly they will be disposed somewhat rearwardly of the packing wheels, with the result that their teeth will simply perforate the ridges formed by the packing wheels which sustain the weight of the frame. It will be appreciated that where the wheels and disks are mounted on a single shaft having a considerable length, the depressed areas of ground may not be reached by said wheels and disks, and the ridges will be unduly compressed, but by use of the construction as described, these objectionable results may be avoided.

*Azs'best shown in Fig. 9, the cylindrical 7 box orsleeve 17 is provided at one of its terminals with a plate 39 which eircumscribes the shaft l6- to prevent a movement in one direction of the ball 24, a movement of the ball in an opposite direction being prevented by the concavedterminal 1' of shaft 15, the

last named shaft being secured to the sleeve by pins 27. It is understood that the ends of theseshafts will project somewhat farther outwardly of the vehicleframe when disposed in alinement than when disposed will slide in the slots 8, as mentioned. As shown in Fig. 1, the packing wheels which are mounted on the cylindrical box or sleeve 17 (said packing wheels being generally one or two in number) are provided with hubs h of such diameter that they will have a bearing upon said box.

Numeral 28 (Figs. 4 and 5.) indicates an aperture for receiving a bolt which may traverse the aperture 29 of strip 30, for mounting a doubletree (not shown), this being comparatively near to the vehicle frame,

said strip 30 being below the tongue and sustained by the spacing-block 31.

. Numerals 32 and 33 indicate apertures formed at longitudinal intervals in link 21 forthe purpose of causing the inner ends of shafts l5 and 16 to be disposed nearer to the V tongue than as above mentioned, when pivotally connected with bracket 28, so that each of the shafts may have an outward and rearward inclinatlon from their lnner ends, the loose pivotal mounting a permittmg this inclination, the result in operation being be imposed in this respect since the scope of the invention is determined by the appended claims.

I claim:

1. An implement for the purpose described, comprising, in combination with a said shafts to permit them to move longitudinally in said brackets and to permit them to swing in a limited are, and means to limit the longitudinal movements of the shafts in said brackets.

2. In an implement for the purpose described, a vehicle frame provided with brackets at its ends, a pair of bearing-heads each being mounted pivotally in a bracket to permit swinging movements substantially at right angles to the line of draft, sleeves provided with slots and mounted in the bear;

ing-heads, a pair of shafts flexibly connected at their inner ends, each of their outer ends bemg disposed in a sleeve, a plurality of crushing elements circumseribing each shaft,

a member engaging one of said shafts and connected w1th the vehicle frame for permitting coincident longitudinal and swinging movements of the shafts and for main taining the shafts during their movements substantially at right angles to the line of draft, and means disposed in the slots of the sleeves in engagement With the shafts for limiting the longitudinal movements of said shafts in one direction.

3. An implement for the purpose described, comprising, in combination With a vehicle frame provided at each of its ends with a bracket, a shaft provided at one of its ends with a ball, a second shaft provided at one of its ends With a cylindrical housing, said shafts being disposed end to end with their outer ends flexibly mounted in said brackets, the ball at the end of the first named shaft being disposed in the cylindrical housing of the second shaft, a Wheel journaled on said cylindrical housing, Wheels journaled on each shaft, a link pivotally supported by the frame and flexibly connected With one of said shafts for permitting the shafts to move longitudinally While swinging in a limited arc, and means on the shafts for limiting their longitudinal movements.
