Application filed December 11, 1911. Serial No. 665,048.

To all whom 2'25 may concern:

Be it known that I, CARL N. DEHLINGER, a citizen of the United States, residing at lVausau, in the county of Marathon, State of lVisconsin, have invented certain new and useful Improvements in Stone-Gathering Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in stone gathering machines.

The primary object of this invention is the provision of a machine for clearing the field of stones or other kindred obstacles,

'which prevents the successful cultivation thereof, although the machine may be employed for clearing surfaces generally of obstructive material.

The machine embodies a rotary gatherer, a plurality of guide fingers, an elevator and a plurality of conveyers arranged adjacent the guide fingers for directing the obstacles thereon.

A further object of this invention is to improve and simplify devices of this character, rendering them comparatively simple and inexpensive to manufacture, reliable and eflicient in use and readily operated.

\Vith the above and other objects in view, this invention resides in the novel features of construction, formations, combinations and arrangements of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which Figure 1 is a top plan view of my invention. Fig. 2 is a side elevation thereof. Fig. 3 is a rear end view thereof. Fig. dis a longitudinal sectional view taken on the line 1% of Fig. 1. Fig. 5 is a transverse sectional view taken on the line 55 of Fig. 1, and Figs. 6 and 7 are detailed sectional views taken on the lines 6-6 and 77 of Fig. 1. 7

Referring to the accompanying drawings by similar characters of reference through out the several views, the numeral 10 designates generally my stone gathering machine which comprises a wheeled frame 11 consisting of opposite side bars 12 connected at their forward ends by a front bar 13 and at their opposite ends by a rear bar 14. The intermediate portions of the side bars 12 have removably secured thereto bearings 15, in which is journaled an thereto a gear wheel axle 16 carrying loosely mounted upon its opposite ends the traction wheels 17. The hubs 18 of these wheels 17 are provided with inwardly extending clutch sleeves 19 which engage slidable sleeves 20 located upon the axle 16 between the said wheels 17 and the bearings 15. V-shaped slots 21 are formed in the sleeves 20 for engagement with pins 22 which extend laterally from the axle 16.

Springs 23 surround the axle 16 and engage the adjacent ends of the bearings and sleeves and serve to normally force the teeth formed upon the outer ends of the sleeves 20 into engagement with the teeth formed upon the inner ends of the sleeves 19. Laterally extending pins 24: extend from the sleeves 20 and serve when properly operated to force the pins 2 into engagement with the extensions of the slots 21 serving to normally retain the clutch teeth out of engagement so that the wheels 17 will remain loose upon the shaft or axle 16.

A pair of inwardly extending bars 25 are secured at their outer ends to the side bars 12 as at 26 and are off-set at their inner ends at right angles to the bar 14 as at 27 to which bars 14: they are secured as indicated by the numerals 28.

A shaft 29 is journaled between the forward ends of the laterally extending portions 27 of the bars 25 and carries keyed 30 and a sprocket wheel 31, the former of which meshes with a gear wheel 32 keyed to the intermediate portion of the axle 16 in such manner that upon the rotation of the said axle through the medium of the traction wheel 17 a rotary motion will be imparted to the shaft 29 and the sprocket wheel 31 carried thereby.

Bearings 33 are secured to the bar 25 and bar 14 and support rotatably thereon longitudinal counter-shafts 34: which carry keyed to the forward ends beveled pinions 35 for intermeshing engagement withbeveled pinions 36 keyed to the axle 16.

Hanger bars 37 are pivotally connected to the rear extremities of the side bars 12 and are connected at their lower ends by a supporting rod 38 to which is vpivotally secured a plurality of spaced guide fingers 39, the forwardly curved terminals of which are connected by a shaft 4:0 and are held in spaced relation to each other by a plurality of spacing sleeves 41 which surround the said shafts with their opposite ends cont-acting with the adjacent sides of the said guide fingers 39.

Threaded rods 412 are pivotally connected at their lower terminals to the ends of the rods 38 adjacent the hangers 37 and extend through bracket plates e13 secured to the bars 25 in which they are adj ustably retained by means of lock nuts 1 1.

Guide plates 45 are secured to the inner sides of the bars 1.2 adjacent the forward ends thereof and have slidably located therein bars 416, the lower ends of which are offset rearwardly at an angle as at 47 and pivotally engage the opposite ends of the rods 10.

A shaft 18 is journaled between the bars 16 in spaced relation from the off-set eX- tensions 17 and has journaled adjacent the inner sides of these bars 41-6 a pair of blocks 19 which are preferably angular in cross section being connected by a plurality of slats 50 from which extend picker fingers 51 which upon the rotation of the shaft 18 are moved between the guide fingers 39 serving to cause the passage of stones or other foreign objects engaged thereby to be moved reaiwvardly over the guide fingers 39.

A sprocket wheel 52 is keyed to each end of the shaft 18 for engagement with the chain 53 which passes over sprocket wheels 54: and 55 carried by the axle 16 and upper extremities of the bars 16, serving upon the rotation of the said axle 16 to cause the rotation of the shaft 48 and the rotation of the picker fingers 51.

An operating shaft 56 is journaled in the bearings 57 secured to the inner side of the bar 13 and carries keyed to its lower terminal a drum 58 which supports a cable 59, the opposite ends of which are secured to the bars 416 being guided. to these said bars by pulleys 60. The shaft 56 has keyed thereto a ratchet wheel 61 which is engaged by a spring pressed pawl 62 adapted to hold the said shaft 56 against any undesired retrograde movcment The pawl 62 is provided with a foot lever 63 by means of which the same may be forced out of engagement with the teeth of the said ratchet wheel 61. Ohviously upon the rotation of the crank 64 formed upon the upper end of the shaft 56 the bars 16 may be raised or lowered thereby raising or lowering the

teeth

39 and 51 relative to the wheels 17.

A pair of

brackets

65 and 66 are journaled upon the shaft 88, the latter of said brackets being extended to engage the shaft 40 which holds the brackets rigidly relative to the frame 11. Channeled plates 67 are attached to the rear end of the brackets 65 and are bent at their opposite ends to produce bearings 68 which support

sprocket wheels

69 and 7 0 over which pass conveyer belts 71 which have attached to their outer sides conveyer plates 72. The shafts which support the sprocket wheels have keyed thereon sprocket wheels 7 3 which engage sprocket chains 74;. These sprocket chains 7% pass over sprocket wheels 75 keyed to the shafts 3 1 and over idlcrs 76 secured to the rear extremities of the side bars 12 by fastening springs 77 so that upon the rotation of the axle 16, a rotary movement will be imparted to the conveyer belts 71 which causes the conveyer plates 7 2 to be moved inwardly.

A pair of bracket arms 78 are secured to the central portion of the shaft 38 and support a channeled plate 79 which is formed at its opposite ends with bearings 80 in which are journaled sprocket .wheels 81 over which passes a conveyer belt 82 equipped with conveyer plates 83 which are longitudinally movable through the channeled plate 79. The rear extremity of this plate 79 is connected to the bar 141 by U-shaped braces 84', while secured to points in spaced relation to the forward ends thereof is a pair of rollers 85 which engage the upper side of the conveyer belt at its opposite edges, holding the same against displacement.

A yoke 86 is secured to the under side of the plate 79 and has journaled therein a shaft 87 which carries keyed thereto a pair of

sprocket wheels

88 and 89 the former of which engages the conveyer belt 82 while the latter engages a sprocket chain 90 which passes over the sprocket wheel 81 and is engaged by a roller 91 which depends from the bar 14 being supported by a hanger 92.

As the machine is propelled over the ground by means of the draft attachment 93 a rotary movement will be imparted to the picker fingers 51 which forces any objects engaged by the guide fingers 39 over the upper ends thereof upon the conveyers 71 which will carry them upon the conveyer 82 from whence they will be directed rearwardly and deposited either in a comparatively straight line governed by the direction in which the machine travels or in a suitable container not shown in the drawinns and which could be attached in any suitable manner to the rear end of the machine.

From the foregoing disclosures taken in connection with the accompanying drawings, it will be manifest that a stone gathering machine is provided for which will.

fulfil all of the necessary requirements of such a device.
