STUlVIP-PULLER.

Specification of Letters Patent.

Application filed June 13, 1911.

Patented Aug. 6, 1912. Serial No. 632,902.

To all whom it may concern:

Be it known that I, WILLIAM H. PARKER, a citizen of the United States, residing at Birmingham, in the county of Jefferson and State of Alabama, have invented a new and useful Stump-Puller, of which the following is a specification.

It is the object of the present invention, to provide a stump puller, the operative portion of which will tilt readily, so as to exert a direct pull upon the stump, independently of the slope of the ground upon which the stump puller rests.

A further object of the invention is to provide novel means for pivotallysupporting the stump pulling mechanism proper, upon the frame portion of the device.

With the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings,Figure 1 shows the invention in perespective; Fig. 2 is a perspective of the bearing member; Fig. 3 is a perspective of the saddle.

In carrying out the invention there is provided a supporting frame, the same preferably, and in its chosen form, embodying parallel sills 1, provided with outstanding axles 2, having pins 3 thrust therethrough, to retain upon the axle 2, the supporting wheels 4. At one end, the sills 1 are connected by a tie 5. Fixed to and rising from the sills 1, are standards 6, united by braces 7 with the sills 1. Other braces 8, rectangularly disposed with respect to the braces 7, unite the standards 6 with the cross bar,

denoted generally by the numeral 9. The cross bar 9 may, if desired, consist of two parts 10.

Superposed upon the parts 10 of the cross bars 9, and secured thereto, is a saddle, denoted generally by the numeral 11. The saddle 11 is provided with a central opening 12, defining side bars 14, and end bars 14. The upper faces of the side bars 14 are recessed, as shown at 15, to form bearings. The adjacent edges of the side bars 14 are also recessed, as shown at 16, so that, at the 1nner ends of the adjacent faces of the side bars 14 there are formed lateral bearing surfaces 17, outstanding beyond the intermediate portions of the adjacent faces of the side bars 14.

The invention further includes a bearmg member, which is denoted generally by the numeral 18. This bearing member 18 comp-rises a body 19, having outstanding trunnions 20, preferably of oval contour, and adapted to register in the bearings 15. The end faces of the body 19 are adapted to bear against the surfaces 17 of the saddle 11. As will'be clearly understood, the engagement between the trunnions 20 and the bearings 15, enables the bearing member 18 to have a pivotal movement upon the saddle. Moreover, by reason of the fact that the end faces 21 of the body 19 of the bearmg member, engage with the faces 17 of the saddle, the bearing member will be prevented from slipping longitudinally upon the saddle. Because the side bars 14 are cut away, as shown at 16, the frictional engagement between the body 19 of the bearing member and the saddle, is reduced, owing to the fact that the side bars 14 are set back, in the intermediate portions of their inner faces, away from the end faces 21 of the body 19 0f the bearing. In the body 19 there is an opening 22, through which moves freely, a screw 23, carrying an eye 24, adapted for connection with a chain or the like, whereby the stump which is to be pulled, may be elevated. The upper surface of the body 19 is flat, as shown at 25, and the edges of the body 19 are rounded, as shown at 26, the saddle being similarly rounded, as shown at 27, to provide for the necessary movement of the bearing in the saddle.

The invention further includes a turning head 28, with which the screw 23 is securely assembled. The head 28 tapers adjacent its opposite ends, and is formed with terminal sockets 29, adapted to receive, removably, a bar 30, whereby the head 28 may be rotated. In the upper face of the head 28, there is a polygonal recess 21, in which is seated a nut mounted upon the upper end of the screw 23, this nut, of course, registering against rotation in the recess 31 the screw 23 moving lengthwise through the nut when the nut is rotated.

In practical operation, as will be readily understood, the head 28 rotates upon the flat face of the bearing 18, the bearing 18 being pivotally mounted, in the manner hereinbetore set forth, upon the saddle 11. Obviously, although the sills 1 may be disposed out of the horizontal, the bearing member 18 will move pivotally in the saddle 11, permitting the screw 23 to have a straight pull upon the stump which is to be withdrawn. When the bar or lever 30 is rotated to elevate the screw 23, the bearing member 18 will be rocked in the saddle 11, notably when the lever 30 approaches a position at right angles to the cross bar 9. When the free, outer end of the lever 30 is depressed, as must necessarily be the case, the bearing membe'r 18 will. be elevated slightly with respect to the saddle 11, because the trunnions 20 are of unequal transverse dimensions, the trunnions being oval inform. Since the bearing member 18 is thus elevated slightly with respect to the saddle 11, an increased leverage upon the stump will result, and at the same time, the body 19 of the bearing member will be prevented from striking against the end bars 14 of the saddle 11 when the bearing member is tilted.

and end bars in the saddle, the side bars being provided with bearings; a bearing member comprising a body registering between the side bars to prevent lateral movement of the bearing member, and trunnions received in the bearings; a screw ex-' tended through the bearing member; and a lever threaded upon the screw and adapted to engage the bearing member; the trunnions being of unequal. transverse dimensions, whereby when the lever is moved, the bearing member will be elevated, thereby increasing the pull upon the stump, the elevation of the bearing member serving to space the body portion of the bearing member against contact with the end bars.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
