BOX ATTACHIWENT FOR TRACTORS- Fowler Richardson, Lebanon Junction, Ky., as-

sig'nor of fifty per cent to Earl'Edward Ryan, Lebanon Junction, Ky.

Application October 24, 1949, Serial No. 123,169

and a novel manner of attaching the box or bed to the tractor.

The primary object of this invention is to provide a box or bed which can be readily and removably attached and detached from a tractor and which, when attached, will be so securely retained on the tractor as to hold articles of substantial weight.

A further objectof this invention is to provide for use with a tractor having a pair of drawbars and upstanding .lugs, an attachment comprising a box having side walls, end walls and a base, means for removably securing said base to the drawbars, and means for removably securing the side walls to the lug, said first-named means including a transverse axle, means for retaining said axle adjacent the front of said box, and means for removably retaining'said drawbarson said axle.

These, together with-various ancillary objects and features of the invention which will laterbecome apparent as the following description proceeds, are attained by the device, a preferred embodiment of which has been illustrated by way of example only in the accompanying drawings, wherein:

Figure l is a top plan view of the bed or box shown attached to a tractor;

Figure 2 is a side elevational view of the device;

Figure 3 is an end elevational view of the device looking from the right of Figure 1;

Figure 4 is a sectional view taken substantially in the plane of section line 4-4 of Figure 2; and

Figure 5 is a fragmentary perspective group view of a detail of construction.

Specific reference is now made to the drawings. In the several views in the accompanying drawings and in the following specification, similar reference characters indicate corresponding elements throughout.

Indicated generally at I0 is a tractor such as the Ford or Ferguson type having rearwardly extending drawbars l2 and I4, upstanding lugs I6 and I8 and. an hydraulic implement control 20. The present invention is indicated at 22 and comprises a box constructed of fiat, relatively wide boards secured together by means of suitable angle irons 24 at all the corners thereof to form a base member 26,

side members

28 and 38, and a front member 32. Intermediate their ends the

side members

28 and 30 are further pro- 2 vided with angle irons 34 to add additional strength to the box.

Welded or riveted 'to the corner angles ad-' jacent the front ends of the box is a transversely extendingtube 36 which receives an axle 38, see

Figure 4; which is longer than the tube. Drawbars l2 and Hi are apertured at their ends and are received on the axle to lie adjacent the free edges of the tube 36. Adjacent-the free ends of the axles, apertures All are provided for'removably receiving headed bolts or pins 42 which are secured by means of chains 46 to an appropriate'lug 46 on each of the drawbars l2 and i4. Thus it will be seen that the box 22 is rigidly but removably secured to the drawbars l2 and 'M of the tractor I0.

Secured by means of appropriate bolts and nuts48 to the

sides

28 and 30 of the box are bars 5Uand 52'which are somewhat arcuated at their attached ends and are upwardly inclined as shown clearly in Figure 2. The bars 50 and 52' are bent or angulated as at 54 to embrace the front corners of the box and are provided with'converging portions 56 and 58'which terminate in lugs'fill and 62'which are apertured as at 64 and spaced parallel to each other.

Secured across the front member 32 of the box intermediate its ends is an angle iron 66 and terminally secured, as by riveting or welding to this angle iron and the corner angle 68 at the front and bottom of the box, is a strap 10 which is crimped intermediate its ends to provide a sleeve 12 that is positioned between the spaced parallel lugs and 62. Secured by appropriate bolts or pins 14 to the upstanding lugs I6 and I8 provided on the tractor I0 is a pair of angle plates 16 and 18 which are apertured as at 8B and 82 and are positioned outside the spaced

parallel lugs

60 and 62 so that the

apertures

80, 64, and 82 are in alignment. A headed bolt 84 is provided which removably extends through the aligned apertures and the sleeve 12 of the strap 10 and is provided with an aperture, if desired, for receiving a cotter pin at its free end 86. The headed end of the bolt 84 is secured by means of an appropriate chain 88 to the bolt 90 that extends through the sleeve 92 conventionally carried on the hydraulic implement control 20 of the tractor. The angulated plates 16 and 18 are further provided with apertures 94 at their corners, the bolt 90 extending through these apertures for additionally securing the plates 16 and 18 to the tractor.

Thus it will be seen that a bed or box is provided which is of sturdy construction to support material of substantial weight and which is removably secured, in rigid fashion, to the tractor ID, the support being at the front end of the box. The bottom of the box is supported on the drawbars I2 and I4 while the sides and the front end are together supported on the upstanding lugs 16 and I8 and the conventional hydraulic implement control 29 of the Ford or Ferguson type tractor. Because of the strap construction 10 which is terminally secured centrally of the front member 32 of the box both at the bottom thereof and intermediate the ends of the front member, and because of the upwardly inclined angulated bars 50 and 52 which embrace the front corners of the box, the box is very well supported upon the tractor at important points. It is also evi dent that while the construction is very rigid, the manner of attaching the box to the tractor is relatively simple.

In View of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.

Having thus described the invention, what is claimed as new is:

1. For use with a tractor having a pair of drawbars and upstanding lugs; an attachment comprising a box havingside walls, end walls and a base, means for removably securing said base to the drawbars, and means for removably securing the side walls to the lug, said firstnamed means including a transverse axle, means for retaining said axle adjacent the front of said box, and means for removably retaining said drawbars on said axle, said second-named means including a pair of upwardly inclined angulated bars receiving the front corners of said box and secured at one of their ends to said side walls adjacent the base, said bars including converging portions terminating in spaced parallel apertured lips at their other ends, a strap terminally secured to said base and front end wall and having a sleeve intermediate its ends disposed between said apertured lips, and means for removably securing said sleeve and lips together and to said upstanding lugs.

2. The combination of claim 1 wherein said last-named means includes a pair of apertured plates secured to said upstanding lugs and disposed adjacent said lips, a pin removably extending through said plates, lips and sleeve, and a chain for securing said pin to said tractor.

3. For use with a tractor having a pair of drawbars and upstanding lugs; an attachment comprising a box having side walls, end walls and a base, means for removably securing said base to the drawbars, and means for removably securing the side walls to the lug, said secondnamed means including a pair of upwardly inclined angulated bars receiving the front corners of said box and secured at one of their ends to said side walls adjacent the base, said bars including converging portions terminating in spaced parallel apertured lips at their other ends, a strap terminally secured to said base and front end wall and having a sleeve intermediate its ends disposed between said apertured lips, and means for removably securing said sleeve and lips together and to said upstanding lugs.
