CORPORATION OF ILLINOIS WHEELED HARROW FRAME Application filed January 26, 1928. Serial No. 249,581.

This invention relates to wheeled harrows and its object is to improve the frame of the disk harrow of my Patent No. 1,531,27 8 patented March 31, 1925.

Since tractor power has come to farming operations it makes it necessary to greatly strengthen the frames of tractor drawn implements and at the same time it is very necessary not to add more weight to such implements or frames, as more weight will cause them to sink their transport wheels deeper in soft soil, making deep marks in the field which are very undesirable and which also increases fuel consumption, and this is a big item with tractor farmers.

With these points in view I have designed a new and different style of frame-using channel iron construction (or channel iron and I-beams) throughout with exceptions of one small iiat gusset brace fitted in the channels at rear of frame.

The object of the invention is Yto provide a strong, substantial and rigid frame, light in weight and simple in construction adapted to carry disk gangs substantially as shown in my former patent andradjustably mounted on wheels so that the frame may be easily raised or lowered as required for regulating the depth of cut and for transportation purposes.

The most important feature of the frame construction is the joint, which is joined together on compression; that is, the flan-ges of .the cross channels arebeveled to accurately fit Vin the channel ofthe I-beam (or channels) in the center of the frame and in the channels on the outside of the frame, but these flanges do not extend to the bottom of the channel or web ofthe I-beam, thus leaving space to draw the joint tighter with bolts shown when wear comes, and at all times using the telescopio effect of the beveled edges of the channels and I-beams and making a oint that will not sag. Y

In the accompanying drawings, illustratf ing a selected embodiment of the invention.

Fig. 4 is a Sectional view .on the line 4-4 of Fig. 5.

Fig. 5 is a detail sectional View indicated on the line 5 5 of Fig. 4.

vReferring to the drawings the frame comprises two substantially L-shaped members consisting of the two centrally disposed forwardly extending bars 6, .6 arranged side by side, and the laterally and oppositely projecting

rear bars

7, 7 which have their

adjacent ends

8, 8 bent forwardly and arranged on opposite sides of the central forwardly extending

bars

6, 6 and parallel therewith and with each other. Bolts 9 extend through the Vends 8, 8 and the bars 6, `6 for securing the

bars

7, 7 to the

bars

6, 6 and a brace 10 overlaps the

bars

7, 7 back of the

ends

8, 8 and is secured to said bars by bolts 11 to form a rigid joint between the

bars

7, 7 and the Abars 6, 6.

The

outer ends

12, 12 of the

rear bars

7, 7 are .also bent forwardly parallel with the

ends

8, 8 and theyare secured by bolts 13 .to the rearwardly extending

side lbars

14, 14 which connect with the laterally and inwardly extending front bars 15, 15j Each pair of

bars

6, 7 constitute an inside frame member and each pair of

bars

14, 15 constitutes an outside frame member and .each .pair `of said frame members constitutes one of the two sections of which the whole frame is composed. All of the

bars

6 and 14 are parallel and extend between front and rear of the frame; the Abars 7 and 15 of each section are parallel and extend between the center bars 6 and the outside bars 14. The rear bars 7 extend outwardly and rearwardly from the center bars and so also do the front bars 15 which are substantially parallel with the rear bars. Each section of the frame is in the form, substantially, of a parallelogram comprising two

members

6, 7 and 14, 15. The

inner ends

16, 16 of the

front bars

15, 15 are bent forwardly and arel arranged on opposite sides of the

bars

6, 6 parallel therewith and with each other and are secured to the

bars

6, 6 by bolts 17. The

cross bar 18 is arranged in each frame section and extends diagonally from the outer end ofthe front bar 15 to the center bar6 substantially midway between the rear bar 7 and the front bar 15. The outer end 19 of the cross bar 18 is bent outwardly to lie substantially parallel with the bar 15 adjacent its juncture with the bar 14 and is secured thereto by bolts 20. The inner end 21 of the cross bar is bent to lie parallel with the center bar 6 and is secured thereto by bolts 22 whereby the outer forward corner of each frame section is braced from the center of the frame to form a strong and substantial structure.

Arms 23 are arranged alongside and on the outside of the

side bars

14, 14, adjacent the rear ends thereof and these arms have inwardly bent ends 24 which are pivoted in bearings 25 on the side bars 14. The rear ends 26 of the arms 23 are also bent inwardly, parallel with the bent ends 24, and they form axles for the carrying wheels 27 and are engaged with adjusting devices V28 pivotally mounted in brackets 28' on the rear end portions 14 of the side bars 14 which are preferably extended beyond the rear bars 7 for this purpose. The adjusting devices may be made as described in the patent to Edward M. Smith, No. 1,740,841, patented December 24, 1929. The arms 23 not only provide axles for the carrying wheels 27, but they also constitute guards for the wheels since they are located outside of and in front of the wheels and protect them against damage from engagement with trees, stumps, fences and other obstructions. The adjusting devices are located between the wheels and the frame and they are connected directly to the axles which are on the rear ends of the arms. This arrangement enables the adjustment of wheels and frame with comparatively little power.

The bars of the frame sections are made of channel iron. The webs 6', 6 of

thebars

6, 6 lie flat against each other and they are lrigidly held in this position by the

bolts

9', 17 and 22, Fig. 4. TheV flanges 6, 6 of these

bars

6, 6 project outwardly and oppositely from the contacting webs 6', 6'. The Vweb 7 of each rear bar 7 is atl the inside of the bar and the flanges 7 of the bars project rearwardly from the rear portion of the bars, but project laterally and outwardly in op- -posite directions at the forwardly bent

parallel ends

8, 12 of the bars. The side bar 14 and the front bar 15 of each section of the frame 'are integral and the web 15' is on the outside Vthereof and the 'flanges 15 project inwardly. The'web 18' of each of the cross bars 18 is at the rear of the'bar and the flanges 18 project forwardly. The flanges 7" of the ends 8 of the rear bar 7, the flanges 18" ofthe end 21 Tof the cross bar 18 and the flanges 15 of the end 16 of the front bar 15 fit within the flanges 6" of the bar 6; the flanges 7" of the end 12 of the bar 7 and the flanges 18" of the cross bar 18 lit within the flanges 15" of the

bars

14 and 15 respectively. By reason of this construction and arrangement of the bars of each section of the frame l am enabled to utilize the flanges for producing a frame construction which will not only be securely fastened together, but which will be free from skewing, twisting or weaving. The inside faces 29 of the enclosing flanges are beveled to receive theinclined outer faces of the enclosed flanges so that the flanges will fit 'smoothly and flatly upon each other and provide a rigid engagement. This also facil-A itates securing the bars of the frame together by means of the bolts because the bolts can be easily tightened to provide an effective clamping engagement of the bars.

The center bars y6, 6 of the frame extend forwardly'beyond the

front bars

15, 15 and have downturned ends 31 whichare spaced apart to receive devicesvfor connecting the harrow to a tractorand for adjusting the front end of the harrow.

The invention provides a strong and substantial frame of simple construction, light in weight, which can be easily manufactured and secured together firmly and rigidly and maintained in this condition throughout service. Utilizing channel bars in the special form, construction and arrangement set forth enables the provision of a strong and rigid frame made of comparatively light material and few parts and withoutthe necessity of many braces. The invention is especially desirable for wheeled harrows which require a strong and rigid frameto stand the shocks and strains and rough usage to which they are subjected, and which should be relatively light in weight. I have shown and described the invention in a selected embodiment which has been found satisfactory in service, but Ireserve the right to make all such changes in the form, construction and arrangement of parts as fall within the scope of the following claims.
