SPECIFICATION forming part of Letters Patent No. 794,736, dated July 15, 1902. Application tiled April 16, 1902. -Serial No. 103,185. (No model.)

To all whom it may concern,.-

Be it known that I, DANIEL W. GOMBS, a citizen of the United States, residing at Needmore, in` the county of Hardy and State of West Virginia, have invented a new Vand useful Attachment lfor Tracti'on- Engines,` 'of which the following is a specii'cation.`

This invention relates to certain improve'- mentsin traction-engines, and hasor its principal object to providean improved form of mechanism in the nature of an attachment which may be applied to any'ordina'ry form of traction-engineV and employed for the pur-- pose of assisting in the movement of the engine over soft road-beds or holes or gullies in the eld and which may also be used as an auxiliary transmitting' mechanism for furnishing power to a threshing-machine or other mechanism requiringpower. v

A further object of the invention is to so construct the mechanism and its supportingframe as to permit of a reversal of a number of the elements to permit the attachment of the device to either a right-hand or a lefthand engine without any change Whatever in the details of construction or mode of operation.

A still further 'object of the invention is to so construct and arrange vthe mechanism as to place the same wholly under the control of the engineer or attendant, the movable members of the shifting mechanism being connected by suitable operating-rods to the rear of the engine.-

With these and other objects in view the invention consists in the 'novel construction and arrangement of parts hereinafter described, illustrated in the accompanying drawings, and particularly pointed out inthe appended claims. A f f In the drawings, Figure lis a longitudinal sectional elevation of an attachment for traction-engines constructed andarranged in accordance with my invention. Fig. 2 is a front elevation'of the principal parts of the mechi anism. Figr is a plan View of themechanism. Fig. 4; isa perspective View of a detail of construction.. Fig. 5 is asimilar view of an improved form of anchor for holding the end of the hauling-line.

Similar characters 'of reference are employed to indicate corresponding parts throughout the several iigures of the drawings.

In the employment of traction-engines for driving and haulingy agricultural machinery an'dsimilar purposes much difficulty is experienced-intraveling the engine over sandy or soft soil and over uneven ground and in other. places where the Weight of the engine causes it to sink deeply intofthe ground or where the-Wheels cannot get sufficient purchase to move the engine or the threshing or other machine to'whichit is attached. To overcome this diiiculty andto provide the engine with an auxiliary power-transmitting shaft, I provide a mechanism which may be secured to the front end of any ordinary form of traction-engine.

In the drawings, A designates the front end of the boiler of an ordinary form of traction-engine, and Bthe maindrivi'ng-shaft, to which motion istrans'mitted by the usual engine. 0n this shaft aremounited a belt or y wheel@ anda sprocket-Wheel D. On each side of the boiler are secured horizontally-disposed bars 10, which may be partially supported by curved bands 11, bolted to the shell of the boiler and to the bars l0. The bars l0 carry vertically-disposed bars 12, united at their upper ends by transversely-disposed bars 13 and 14 and connected by brace-bars 15 to the bands 11, so as to form a rigid structure, and near the forward end of each bar 10 is secured a vertical bar 17, connected to the horizontal bar by a'diagonally-disposed brace 18. LThese bars constitute Ythe main supporting-t rame of the attachment; but an auxiliary frameA comprising apair of horizontally-'disposedbars 2O vand a cross-bar 2l i's bolted to onesid'e of the main frame in such manner that its position may be reversed when necessary to suit the style of traction-engine to which it is to be applied or, in other words, vto accommodate engines having the'driving mechanism on either theright-handside or the left-hand side of the boiler. of the auxiliary frameare secured bybolts 22 to the vertically-disposedbars 12 "and 17, and as the arrangement of these bars is the same on each side of the mechanism the auxssi The bars 20 ICO ` 23'for the reception and support of a horizon- ,pinions 29, before referred to.

tally-disposed shaft 24, the bars being preferably provided with passages 25, through which lubricant may be supplied to the bearings. The shaft 24 carries a winding-drum 26, having end flanges 27, and to the end flanges and the shaft are secured gear-Wheels 28, which may be intermeshed with drivingpinions 29, secured to a shaft 30, when it isV desired to revolve the winding-drum. One end of the shaft 24 extends out under the auxiliary frame and is supported by a hanger 3l, depending from said auxiliary frame, While on the extreme end of the shaft is secured a worm 32, which may engagea Worm-wheel 33, carried by a shaft 34, adapted to bearings on the auxiliary frame. This shaft 34 acts to reciprocate a traverse mechanism for properly guiding the hauling-line to the Winding-d rum, as more fully described hereinafter.

Near the upper end of the bars 17 is fulcrumed a rectangular frame 35, the oppositeend of which rests on suitable stops-'36, projecting from the vertical bar 12. The pivoted frame is provided with blocks 37 for the support of the shaft 30, which carries the driving- On one end of the shaft is secured a sprocket-wheel 38, to which motion is imparted from the main driving-sprocket D through the medium of link-belt 39. The opposite end of the shaft 30 projects out beyond the outer end of the auxiliary frame 2O 'and carries a belt-Wheel 40, to which may be attached a suitable belt to a threshing or other machine requiring power. Near the outer end of the shaft 30 is a bearing-block 41, carried by a bar 42, having end sockets tting over the upper ends of standards 43, carried by the auxiliary frame 20, there being suitable openings 44 arranged at each standard and a similar opening 45 at each end of the bar 42 for the reception of a locking-bolt 46, which may be employed to lock the bar in either elevated or depressed position and in either case serving to rigidly hold said bar and so support the outer end of the shaft 30.

Extending rearwardly from each bar 12 is a bracket 50, in which are journaled the opposite ends of a rock-shaft 51, the latter serving to support a pair of notched disks 52, arranged one near each end of the shaft. disks are provided With alining notches forming shoulders 53, adapted to engage the rear bar of thepivoted frame 35, and when the rock-shaft is turned said shoulders serve to elevate the frame and separate the teeth of The the gears 28 and 29 or when turned in the opposite direction permit the descent of the frame by gravity to intermesh said gears. To the rock-shaft is secured an arm 55,-from which extends a connectingrod 56 to any suitable point on the machine within convenient reach of the engineer.

57 designates a rod having a horizontal portion guided in suitable openings in the bar 12 and bracket 50, one of such rods being disposed on each side of the machine. The forward ends of the rod project over the top of the pivoted frame 35 when the latter is in the depressed position (shown in Fig. 1) and serve to hold the frame down and keep the gearteeth intermeshed. When the frame is elevated with the gear-Wheels disconnected, the rods serve as a support for holding said frames in the elevated position, excessive up- Ward movement of the frame being prevented by stops 58, carried by the vertical bars 12. After passing rearwardly through the vertical arm of the bracket each of the rods 57 is provided With a downwardly and inwardly bent portion 59, adapted to engage in one or other of a pair of locking-slots in the disk 52. When the arm 59 is iny engagement with the lower-most slot 60, the frame 35 is in the lowest position, and any rotative movement is prevented by the engagement of the arm and slot, while the movement of the arm into the slot 61 serves to lock the disk against rotative movement when the frame 35 is elevated. To provide for the movement of the locking-rods, I employ a rock-shaft 60', the opposite ends of which are adapted to suitable bearings in the opposite side bars 12. Secured to said shaft at points just within the bars 12 are a pair of rocker-arms 61', having suitable openings for the reception of arms 62, projecting laterally from the rods 57 through suitable slots formed in the inner faces of the bars 12. The arms 6-1 are normally held forward or in the locking position by springs 63, having one end connected to the arms and the opposite end connected to the vertical arm of the bracket 50. The rock -shaft 60 is further provided With an arm 65, the upper end of which is connected by a rod 66 to any suitable operating -lever or handle Within convenient reach of the engineer. Y

When the mechanism is in the position illustrated in full lines in the drawings, the teeth of the gears 2S and 29 are engaged, and power is transmitted to the Winding-drum 26 to eect the Winding of a hauling-line 67, the opposite end of which may be secured to a suitable anchorage and the winding up of the line serving to cause a forward movement of the engine. At this time the locking-rods 57 are in engagement with the upper surface of the frame 35, so that any upward movement of said frame is prevented, while the disks 52 are also held from rotative movement by the engagement of the arms 59 of the locking-rods in the slots 60. When the engineer IOC) IIO

wishes to disconnect the gear-wheels and employ a shaft 30 and its beit-wheel 40 as a means of transmitting power to a separat-e mechanism, such as a threshing or other machine, he first removes the pins 46 from the alining opening 44 and 45 of the block-carrying bar 42 on the auxiliary frame. The rods 66 are then pulled toward the rear, moving the locking-rods out of engagement with both the pivoted frame and the disks 52. When the rods are in unlocking position, the rod 56 is pulled to the rear, causing an angular movement of the rock-shaft 51 and the disks 52, the shoulders 53 of the latter engaging with and raising the frame 35 until the rear end of the latter is at a point above the level of the locking-rod. The locking-rods are then released and are moved forward by the springs 63, the forward ends of said rods passing under the frame 35 and holding the latter in elevated position, while the arms 59 of said rods pass into the slots or notches 61 and lock the disks against further rotative movement. The pins 46 are then inserted in the proper openings of the auxiliary-frame standards 43 and bar 42 to form a rigid support for the outer end of the shaft 30.

When the winding-drum is being employed to wind up the hauling-line 67, it becomes desirable to employ some means for properly guiding the rope on the drum and to prevent chafing the line. main frame are secured two transversely-disposed bars 70, having guiding-grooves in their adjacent faces for the reception of a substantially rectangular sliding frame 71, to the upper and lower bars of which are secured spindles for the reception of guiding-rollers 72, between which the hauling-line 67 is passed. One end of the frame 71 is connected by a rod 73 to a crank 74, carried by the shaft 34, and

as saidV shaft is rotated by the worm 32 and worm-wheel 33 the slide receives a reciprocating movement as the drum revolves. The worm-gearing is so proportioned that the slide 71 will be moved once across the face of the drum during the time required for the drum to receive one complete coil or layer of the line, so that the latter will be wound evenly and regularly, while the rollers 72 serve to prevent any chaiing of the line. Projecting from the upper front end of the main frame are a pair of brackets 80, connected to the upper guide-bar by braces 81, the latter being in turn connected to the vertical bars 12 by braces 82 in order to make the frame as rigid as possible. In the main frame and in the brackets 8O are bearings for the support of the reduced end portions of a pair of horizontallydisposed rollers S3 and a pair of vertically-disposed rollers 84, the whole presenting an antifriction-surface with some portion of which the hauling-line is always incontact.

When the usual driving mechanism of the engine is insufficient to propel the engine when applied in the ordinary way, the haul- To the forward end of the ing-line is attached to some stationary point, as a tree or other object, and the windingdrum is revolved to wind up the line and cause the forward movement of the engine, and in similar manner the engine may be anchored or blocked up in any suitable manner to prevent movement and the end of the line attached to an agricultural orother machine which it may be desired to move. When any natural anchorage is not accessible, I employ the apparatus shown in Fig. 5 to hold the outer end of the line. This apparatus comprises a curved blade 90, preferably having a toothed lower edge, as indicated at 91, and

provided with eyes 92 for the reception of the curved ends 93 of a bifurcated frame 94, the opposite end of which is provided with a yoke 95, adapted to embrace a post or stake 96, which is driven into the ground at a convenient distance from the engine. The stake 96 has one or more openings for the reception of a pin 97. When the `anchor is to be .employed, the lstake is driven into the ground, and over said stake is placed a ring 98, secured to one end of the hauling-line. The pin 97vis then inserted in one of the openings at a point above the ring to prevent the latter from sliding off over the top of the stake. The blade is then placed under the line, and the arms of the frame 94 are inserted in the eyes 92, the line passing through the frame, as shown in Fig. 5. The toothed portion of the blade is. then forced into the ground and the frame bent down until its yoked end is in engagement with the upper portion of the stake, thus forming a brace and support for the stake and preventing any movement of the latter during the winding of the line. In some cases the blade 90 may be dispensed with and the pointed ends of the arms 93 forced into the ground, although in loose soil it is preferred to employ the blade, owing to the increased surface area of thev anchor in contact with the ground. As a convenient means of carrying the anchor when not in use I employ a suitable hook 99, carried by the upper transverse bar 13, and a yoke or guard 100, carried by the bar 14 of the frame.

The attachment is of simple and inexpensive construction and, as before described, may be readily applied to either a righthanded or left-handed engine by changing the position of the auxiliary frame and the parts carried thereby and reversing the position of the shafts 24 and 30. The attachment may also be employed on stationary or other engines for transmission of power or for the purpose of employing the drum and hoisting-line to raise weights or operate a crane or similar mechanism.

While the construction herein described and illustratedv in the accompanying drawings is the preferred form of the device, it is obvious that various changes in the form, proportions, size, and minor details of the IOO IIO

structure may be made Without rdeparting from the spirit or sacrificing any of the advantages of the invention.
