6 Claims.

This invention relates generally to hay rakes, tedders and the like and is more particularly concerned' with the reel structure usually incorporated in an apparatus of this type.

And the present invention is directed toward and has as an object the provision of a reel structure incorporating features of improvement as to construction and mounting affording a material reduction in the time, effort and skill required to assemble or disassemble same.

Another object and feature of this invention is the provision of a reel structure utilizing interchangeable parts and detachable reel-bar bearing mountings permitting these bars to be separately removed and replaced or serviced, as required.

Still another object of this invention is the provision :of a reel structure incorporating improved features of construction for reel bars havin crank extensions adapted to be journaled in peripheral bearing portions of a spider element whereby the reel bars may be assembled on the reel structure either before or after the spider element has been operativelymounted thereon;

A further object of this invention is to provide a durable reel structure incorporating features of simplification as to construction and assembly affording material advantages as to cost of manufacture and maintenance.

The construction, assembly and operation of apparatus embodying the invention will become readily apparent as the disclosure progresses and particularly points out additional objects and advantages considered of special importance. And accordingly,'the present invention may be considered as comprising constructions, combinations and subcombinations of elements, including parts thereof, as is hereafter more fully set forth in the detailed description and appended claims. And for a better understanding of the construction, assembl and operation of an illustrative app-aratus, attention is directed to the accompanying drawing illustrating but one embodiment of the invention and in which:

Fig. 1 is a plan view of a rake reel assembly and mounting with certain parts omitted in the interest of simplicity;

Fig. 2 is a view in elevation of the left end of the structure shown in Fig. 1;

Fig. 3 is a view in elevation of the right end of the structure shown in Fig. 1 with parts omitted in the interest of simplicity; and

Fig. 4 is an enlarged longitudinal vertical section through the right end of the reel assembly shown in Fig. 1 with parts further cut away to better show the construction.

As best seen in Figs. 1, 2 and 3, the reel mounting frame structure comprises parallel front and rear side members I and 2, respectively, having their left hand end portions interconnected by a bar 3, having theright hand end portions connected by an angle member 4 and having longitudinally spaced opposed portions interconnected by bracket forming stripper bars 6. This frame structure also includes a rigid beam I which has its rearend fixedy secured to a plate 8 attached in bracing relation to the rear left hand corner ofthe frame structure and which extends for- -wardly over the frame structure in upwardly arched oblique relation thereto. The mid portion of the front and rear frame members are interconnected by an upwardly arched brace 9 having its forward end attached to member I in underlying relation with respect to beam I. A for- .wardly projecting beam II has its rear end fixedly secured to a right hand extension of member 2 and extends forwardly therefrom beneath front member I in spaced underlying relation thereto. Angle member 4 also extends forwardly beneath member I in underlying spaced relation thereto and is secured therewith by means of a spacer tube I2 through which passes the adjacent end of a basket forming bar 6, the latter having a threaded end portion which passes through an aligned aperture in front member 5 and is fixed thereto by means of a nut I 3. The forwardly extending beam I I may also be secur d to the overlying portion of member I in substantially the same manner as just described with respect to angle member d. The left side of the reel frame includes a, U-shaped bearing supporting bracket I 4 secured in depending relation to the mid portion of bar 3, the latter being braced by a member M5 connecting an intermediate portion thereof with a portion of beam I spaced from plate 8 and rear member 2. The right side of the reel frame also includes a U-shaped bearing support bracket H (see Fig. 3) secured in depending relation to a portion of angle member 13 intermediate its point of connection with front and rear side frame members I and 2. A brace member I5 connects the reel bearing supporting portion of angle member 4 with an opposed portion of beam II. The frame structure just described is adapted to be supported in part by a pair of ground engaged wheels (not shown) and in part by a forwardly extending draft structure (not shown) including as elements thereof the forwardly converging beam members I and II.

A pair of opposed reel stub shafts I8 and I9 are rotatably mounted in bearings ZI and 22, re-

mounting disc '31 to turn-relative thereto.

spectively, including rectangular housing structures having grooved opposite sides guidedly engaged with the inner opposed edges of U-shaped brackets l4 and I1, respectively. These bearing structures are suspended for vertical adjustment relative to brackets l4 and I! by means of chains, cables, orthetlike, 23 :andid which, pass over suitable .frame mounted pulleys or equivalent guiding elements 26 and 21, respectively, and are adapted to be connected with a suitable COI1VBI1-. tional adjusting means such as levers or the like (not shown). The opposite ends of stub shafts t8 and I 9 are united and in effect made continuous by an interconnecting.tubeshaftQZS fixedly secured in telescoping relation to. the opposite:

ends of these stub shafts in any suitable manner such as by pins, cap screws or the liken-as shown in Fig. 4. The portion of stub shaft IBMadjacent bearing '2 I, the mid portion of tube shaft 29, and

the portion of stub shaft 19 adjacent bearing 22 each has .a similar reel-bar supporting disc 3| keyed or otherwise secured --thereto, these'discs each presenting a peripheral fiange 32 generally parallel to the axis of shaft'ZB. A plurality of similartine carrying reel bars 33 are detachably secured to the-outer peripheral surfaces of flanges I 32in,circumferentially spaced'relation with respect to each 'other by 'means of similar bearing and: strap elements-34 and 36; respectively. As shown reel bar 33 comprises 'a pair-of-tubular members 25 and 3!! secured irrtelescoping relation to opposite'endsof a 'stub shaft-35 inany suitable manner such as--described infrelation to stub shafts, l8 and" L9. The left ends of each tubular member 25 are-secured in telescoping relation to a stub-shaft 45 in a conventionalmanner and the right ends of each tubularmember 39 are likewise secured'to acrank-extension 39. The left end, the'rightendand the midportion of each reel bar 33, that 'isstubshafts '45, 35" and crank senting a depending positioning boss adapted to i be inserted in a hole 31 in disc flange 32. "These bearing structures are also provided-with a top surface having a pair of circum'ferentially extending spacedparallel ribs 29 forming a groove 1n which isdisposed a strap elementsfi including.

oppositely extending-feet"portions 38 which are bolted or otherwise fixedly secured to the outer peripheral surface'of fiange 32-on each-side of a-bearing structure-as best shown in'F'ig. 3.

1 Each reel bar 33 is provided with-a crank extension 39 rotatably journaled in opposed peripheral bearing portions 4! of acontrol spider "42 having a hub 'part lll'providedwith-acircumferentially grooved inner surface 43-coaxial with respect to the crank-receiving bearing portions thereof. Spider '42 ,"is 'rotatably' supported-on a coaxial group of ribbed rollers 'M detachably mounted on a member which'is in turn eccentrically mounted on stub 'shaftls preferably between bearing'22 and the adjacent reel bar The ribbed surfaces'o-f rollers 44 are complementary to and supportingly engage'the inner grooved surface 43 on spider hub 49 thereby-retaining the spider, rollers,- and the roller carrying member in correct operative relation. In this connection it should be noted that the depth of the groove in surface 43 is greater than the height of the ribs on rollers M. Member 45 may be turned to and retained in any selected position by means of an arm 41 having its remote end pivotally connected with a forwardly extending rod 48 which in turn is operatively connected with an actuating means such as a lever or the like (not shown). Movement of member 43 varies the angular position of spider 32 with respect to the reel disc bars 33 and thereby the angular position of these bars and of the tines mounted "thereon, the tine bars responding to a' movement of member 46 and spider 42 by turning in'their bearing structures 34 detachably :secured to the flanges 32 on reel bar supporting discsSl.

Theouter end of stub shaft 19 is provided with a reeldrive clutch assembly comprising an element 49 keyed to' shaft 1 9 "for rotation therewith and a sprockettwheel element 51 rrotatable relative to' 'el'ement dll Sand 're'lea'sably "engaged thereto by meanslof 'coacting teeth '52 and a compression spring 53l'surrounding shaft 19 and retained-thereon inoperative engagement with sprocket" "element 751 by means "of *spring 'seats 54 and nuts" -06 The arrangement 'ofithese clutch elements is such that elements 49 and 5! are normally engaged todrive shaft l9ibut are autom'atic'ally disengagedto prevent damage'whenever' thedriven load becomes excessive; Sprocket 'element'fil is "adapted to bedrivemthrough a chain connection?! with a conventional drive sprocket (not shown) It should now =be-fobvious ithat tinebars 33 ma y' beseverally'attached to and removed: from reel'bar disc 3 simply by removing the "retaining strap elements '36 and withdrawing thejourparatus constructed :in accordance with this invention (assuming reel bars 33 have been fabricated in the'manner hereinbeforeset forth), the journal portions of tine bar crank extensions 39 are then'inserted'in spider bearings M, assuming the latter is already mounted on stub shaft l9, and the assembly is completed .by bolting the straps 36 to the flanges 32 of the reel bar supporting discs 3| as previously indicated. Obviously spider 42 may be positioned on the journal portions of crank extensions 39 after bars -33-have .been secured to reel discs 3|.
