This invention relates to attachments for tractors and the like and more particularly to improvements in sweeper apparatus par- One of theprimary objects of theprescnt invention is to provide a device of the above character distinguished by its simplicity of construction and operation which-not only enhances its value both mechanically and commercially, but provides a design of a. strong and durable nature.

Swcc oer attachments as new commercially produced require the presence of several sprocket gears and chains connecting the sprocket gears for actuating the sweeper from the power take off of the tractor. Sprocket gears and their connecting chains are not only inefiicient because of the lossof power result ing from their use but. are also the source of trouble mechanically because of strains imparted thereto.

However, according to my invention I propose an improved driving connection betw en the power takeoff of the tractor and the rotatable brush for the sweeper which offers the possibility of "eliminating complicated and inefficient sprocket- 'andchain connections and providing an arrangement which is con ducive to advantages not possible with the above described type of sweeper attachments.

A further feature of this invention resides in the novel manner in which the sweeper brush is hinged upon the frame so thatthe brush may be quickly and easily swung to inoperative position without binding any of the parts.

Other objects and novel features of construction will be made more apparent as this description proceeds especially when'con sidered in connection with the accompanying drawings wherein:

Figure 1 is a side elevation of atractor with my improved sweeper attached thereto;

Figure 2 is a top plan view partly in section, of the structure illustrated in Figure 1, certain parts being broken away for the sake of clearness;

Figure 3 is asectional view taken on the line 3-3 of Figure 2;

Figure dis a sectional view taken on the line 1l of Figure 2.

Referring now more particularly to the drawings it will be noted thatthere is illu'stinted tract-or 10 having front and rear axles l1 and 12 upon which wheels 13, herein conventionally shown, are mounted.

The attachment embodying my inwention includes'the frame l l comprising a pair of argularly spaced frame members 15 secured together at the inner ends thereof by means of the bracket/'16 which in turn is bolted or otherwise suitably pivotally secured to the lug 1'? depending from the tract r casing. Secured to the frame members 15 intermediate theends thereof is a cross brace 18 which shown is pivotally secured intermediate the ends thereof to the front axle 11 by means of the longitudinally extending bolt l9. lVih this arrangement it will be apparent that the frame l l will follow the axle during the rocking movements thereof so that a perfeet contact of the rotatable brush with the I road is insured.

Secured to the outer ends of the frame members 15 and extending at an angle to the longitudinal axis of the tractor is a second cross brace 20 having secured upon the opposite ends thereof the brackets 21 and22. Each of these members is provided with axially aligned bearing portions 23 and 24 within which a second pair of brackets 23 and 24 are respectively journalled. As shown, the 1 brackets 23 and. 24 are substantially triangular in shape. and are provided with bearings 25 at the upper ends thereof for receiving the 'rod 26. This rod is preferablycon- 'nected intermediate the ends thereof with the lever 27 pivoted asat 28 to the tractor. The bracket 24 is further provided at the outer end thereof with a bearing 29 within which one end of the brush shaft 30 is journalled.

The opposite end of the brush shaft is journalled within the annular housing 31 cast integral with the braeket23 and disposed in axial alignment with the bearing 29 formed in the bracket 24.. As shown, the bracket 23 is provided with an inwardly extending projection 32 having a bearing portion 33 within which one end of a shaft 34 is preferably Lournalled, the opposite end of this shaft eing journalled within and extending through an extension 35 of the housing 31. Non-rotatably mounted upon the shaft 34 and arranged within the extension 35 is a worm gear 36 adapted to mesh with the worm wheel 37 disposed within the housing 31 and keyed or otherwise suitably secured to the brush shaft 30. For rotating the shaft 34 and consequently the brush, I provide a drive shaft 38 driven from the power take off of the tractor, in a manner to be more fully hereinafter described and universally connected at the forward end thereof to the shaft 34 by means of the cooperating coupling members 39 and 40 upon the shafts 34 and 38 respectively. As shown, the coupling members 39 and 40 are of conventional design and are arranged in the same horizontal and vertical planes with the bearing portions 23 and 24 for the brackets 23 and 24. In other words, the center of the coupling designated by the character 41, is in direct alignment with the axis of the bearing portions 23 and 24. Thus it will be noted that the brush may be quickly and easily swung to inoperative position with comparatively little effort as any tendency of the parts to bind is thoroughly eliminated owing to the fact that the shaft 34 carrying the worm 36 swings in an arc coincident with the are described by the housing 31 or worm wheel during the pivotal movement of the brush.

Referring now more specifically to the means for driving the drive shaft 38, it will be noted that this shaft extends inwardly to a point adjacent the power take off point of the tractor and is coupled with a shaft 42 journalled within the casing 43 and connected through a suitable clutch indicated generally by the reference character 44, to a second shaft 45 having a gear 46 secured thereto and meshing with a gear 47 keyed to the shaft 48. The shaft 48 is driven by the customary power take off mechanism not shown. Any suitable means may be utilized for shifting the clutch to either engage or disengage the operating shaft 38 with the driven shaft, herein shown as comprising an operating lever 49 having a fork 50 upon one end thereof engageable with the clutch 44.

With an arrangement such as herein described, it is apparent that a mobile sweeper is provided in which the brush is rotated by power obtained from the tractor without the use of sprocket wheels and the accompanying chains.

\Vhile one specific embodiment of the invention has been illustrated and described herein in some detail, it will be readily apparent that various modifications may be resorted to without departing from the spirit and scope of this invention and to this end reservation is made to make such changes as may come within the purview of the accompanying claims.

What I claim as my invention is:

1. An attachment for tractors including a frame rigidly attachable to a part of a trac- I tor, a bracket pivotally connected to the frame and having a lateral projection, a sectional housing in rear of the lateral projection, one section of said housing constituting a part of said bracket, a ground engaging element having a shaft journaled in the sections of the housing, and actuating means for said element including a shaft journaled in the lateral projection aforesaid and extending into said housing, and cooperating rotary parts within said housing operatively associated with the first and last mentioned shafts.

2. An attachment for tractors including a frame attachable to a part of a tractor and having a cross bar, brackets pivotally mounted on said cross bar, a housing carried by one of said brackets, a ground ongaging element having a shaft journaled in said housing and in the other bracket, arod carried by said brackets, means connected to said rod to move said ground engaging element and brackets relative to said cross bar, and actuating means for said element including cooperating rotary parts within said housing and operatively connected to the shaft of said element, and two universally connected shafts for operating said cooperating parts, the universal connection between said shafts being entirely separate and spaced from but in substantially horizontal alignment with the pivots for the brackets whereby one of said shafts may move with said brackets relative to the other shaft as said brackets and ground engaging elements are moved relative to said cross bar.

3. An attachment for tractors including a frame attachable to a part of a tractor and having a cross bar, brackets pivotally mounted on said cross bar, a housing carried by one of said brackets, a ground engaging element having a shaft journaled in said housing and in the other bracket, .1 rod carried by said brackets, means connected to said rod to move said ground engaging element and brackets relative to said cross bar, a bearing on the first mentioned bracket, and actuating means for said ground engaging element including a shaft journaled in said bearing, and cooperating rotary parts within said housing and operatively connected to the shaft of said element and to the last mentioned shaft.
