Appneauon filed January 9, 1925. serial no. 1,500'.

Tov all 'whom 15 may con/fern.' y

Be it known that l, WILLIAM RALPH SILVERTHORNE, a subject of the' King of Great Britain,'and a resident of the village of Shell Brook, the ljrovince of Saskatchewan, Canada, have invented certain new and useful Improvements in Harrow Lifters, of which the following is the specification. l i

My invention relates to improvements in harrow lifters, and the object of-r the invention is to devise a simpley and convenient means whereby any one of the harrow sec 1 and 2 indicate carrier wheels provided' with stud axles 3, each axle being provided with an upwardly vertical extension 4.

The stud axles 3 are connected'together by angle bars 5 and 6 .which are connected together by plates 7.

8 are standard brackets secured at their foot end as indicated at 9, to the angle bars 5 and 6, serving also to connect such angle bars together.

The upper end of each standard bracket 8 is outturned as indicated at 10, to form an upper hearing support for the vertical portion 4v of the stud axle 3, the lower end of such vertical portion being permanently held in the cross plates 7, asV clearly indicated in `fig. 2.

The lower portion of the stud axle is provided with an enlargement 11 bearing against the lower face of the plates i", a nut 12 being threaded intermediately of the ver tica-l portion 4 against the out-turned portion of the bracket 8..

By this means, the axles are held permanently in position and from vertical movement.

13 are arms which'are' secured tothe upper ends of the portiens4 ef the' stud axles 3, such arms exten-ding forwardly and connected together inl proximity toV their forvward ends by a' cross bar 14, suchcross bar carrying-a series of loops or eyelets'f15, for a purpose which' will hereinafter appear.

The' crossv bar 14 is pivotally connected to each arm 13'by a pivot bolt 16'.

17 is a transverse bar on which are mounted pulley blocks 18, 19, 20, 21, 22, 2323*, 24 and 26 is a draft army which is preferably V shaped in form, the arms of the V being provided with saddle portions 27 extending over the transverse bar 17, and secured thereto, the extreme ends of the arms extending downwardly, as indicated at 23, to the angle bars 5 and@ extending transversely of such bars, as indicated at 29, (Fig. 2), being secured thereto by bolts 30 further securing the bars 5and 6 together.

31 are a series of harrow sections connec'ted to the harrow beam 32 to which the harrows are connected by chains 33 in the usual manner.

34 is a block secured to the beam 32 intermediately of its lengt-h.

35r is a goose neck formed at the apex of the V shaped harrow lifting arm 26, such goose neck depending therefrom and being provided with a foot 36 resting upon theV block 34 and connected thereto by a king bolt 37.

x38 and 39v are tie rods having hooks 40 at their upper ends extending through oriii'ces 41 of the arms 13, and at their opposite ends being provided with hooks 42 extending' through orifices 43 formed in brackets 44 which are pivotally connected, as indicated at 45, to the harrow beam 32.

By this means a flexible connection is formed between the ends of the arms 13 and the lha-rrow beam 3.a, permitting the arms 13 to have a limited swinging movement to permit the carrier wheels 1 turning in the desired direction to follow the harrow.

It will of course be understood that as the barrow is drawn over the ground, in

turning, the harrow beam swings horizontally and a pull is exerted either on one tie rod or the other, which thereby swings the arms 13 connected together by the cross bar 14 in the desired direction to turn the wheels 1 and 2 in unison. Y

46, 47, 48, 49 and 50 are cords or cables, each cord being connected to a harrow section 31. The cord/i6 passes upward over the pulley block 18, and then passes longitudinally of the bar 17 around the pulley block 2O and through an eye 15, the end of the cord depending and formed into a loop 51. Y

Similarly, the cord 47 is connected to the next harrow section in succession and passes upward over the pulley block 19, and then transversely of the machine between-the bar 17 and from thence through the next eye 15 in succession, its depending end being also formed into a loop, as indicated.

The cord 48 passes upward from thethird harrow section in succession, over the pulley block 22 and through the third eye 15, its depending end also being in loop form.

The cords 49 and 50 pass upward from the 4th and 5th barrow sections and over the

pulleys

24 and 25, passing transversely of the machine round the pulleys 23 and 23X, through the 4th and 5th eyes 15, the ends being also formed with loops.

The loops 51 Iform hand-grips by which the operator seated in the seat 52, by pulling upon any one of the

cords

46, 47, 48, 49 or can independently raise any one of the harrow sections 31 so as to free it from weeds or any othermatter clogging thereon.

From this description it will be seenthat I have devised a very simple form of harrow lifter which will be very effective, easily operable, and which will follow the harrow in any desired direction.

lhat I claim as my invention is:

1. The combination with a harrow beam, and the harrow sections connected thereto, of a barrow lifter comprising a follower carriage provided with stud axles, a pair of carrier wheels mounted on the stud axles, a transverse member connecting the axles together, a vertical extension to each axle, means for turnably mounting each vertical extension on the transverse member, means connecting the vertical extensions to the barrow beam whereby the horizontal swing of the harrow beam is transferred to the vertical members to turn them in a corresponding direction to guide the carrier wheels to track with the harrow.

, 2. The combination with a harrow beam, and the harrow sections connected thereto, ofa harrow lifter followerr carriage comprising a pair Vof carrier wheels provided with stud axles, a transverse member connecting the axles together, a vertical extension to each axle, means Ifor turnably mounting each vertical extension on the cross member, means connecting the vertical extensions to the barrow beam whereby the horizontal swingV of the barrow beani is transferred to the vertical members'to turn them in a corresponding direction to guide the carrier wheels to track with the harrow, and means whereby the carriage wheels are turned in unison.

3. The combination with a barrow beam, and the barrow sections connected thereto, of a harrow lifter follower carriage comprising a pair of carrier wheels provided with stud axles, a transverse member connecting the axles together, `a vertical extension to each axle, means for turnably mounting each vertical extension on the cross member, means connecting the vertical extensions to the harrow beam, an arm extending forwardly from each vertical extension, a cross rod pivotally connecting the arms together, tie rods extending from eachy arm and crossed intcrmediately of their length and pivotally connected at their opposite ends to the harrow beam, and means connected to each barrow section whereby each harrow section may be independently lifted by the operator from a point behind `the follower carriage.

4. The combination with a harrow beam, and the harrow sections connected thereto, of a harrow lifter follower carriage comprising a pair of carrier wheels provided with stud axles, a transverse member connecting the axles together, a vertical extension to each axle, means for turnably mounting each vertical extension on the cross member, means connecting the vertical extensions to the harrow beam, an arm extending forwardly from each vertical extension, a cross rod pivotally connecting the arms together, a series of parallel pull cords guided on cross rod, tie rods extending from each arm and crossed intermediately of their length and pivotally connected at their opposite ends to the harrow beam, a transverse bar member carried by the harrow vbeam arm, and pulley blocks mounted thereon around which the aforesaid pull cords extend individually from each barrow section.

5. The combination with a harrow beam and the harrow sections connected thereto, of a barrow lifter follower carriage comprising a pair of carrier wheels' provided with stud axles, a transverse member connecting the axles together, a vertical extension to each axle, means for turnably mounting each verticaly extension on the cross member, means connecting the vertical extensions to the harrow beam, anarm extending forwardly from eachverti'cal extension, a cross rod. pivotally connecting the arms together, tie rods extending from each arm "and crossed intermediately of their length and pivotally connected at their opposite ends to the harroW beam, a transverse bar member carried by the draft arm, pulley blocks mounted thereon, a cord ex tending from each barrow section and guided by the pulley blocks and extending in transverse series over the bar connecting the arms extending from the vertical extensions of the axle arms, eyes carried by such transverse bar through which the cords individually pass, and a loop formed by the depending portion of each oord to form a hand-grip whereby each oord may be independently pulled by the operator.
