ROLLA IIEATON, OF MARCELLINE, ILLINOIS.

POST-DRIVER.

SPECIFICATION forming part of Letters Patent No. 610,811, dated September 13, 1898. Application led December 15, 1896. Serial No. 615,812. (No model.)

To @ZZ whom t may concern:

Be it known that I, ROLLA I-IEATON, of Marcelline, in the county of Adams and State of Illinois, have invented certain new and useful Improvements in Post-Drivers; and I do hereby declare the following tobe a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the letters of reference marked thereon.

This invention relates particularly to improvements in devices for building fences, especially wire fences, and has for its object to provide a device constructed entirely of metal and which can be mounted on awagon for driving the posts; and it consists in certain novel details of construction and combinations and arrangements of parts, all as will now be described, and pointed out particularly in the appended claims.

In the accompanying drawings, Figure lis a side elevation 0f the machine mounted on a wagon with wheels shown in dotted lines. Fig. 1L is a detail perspective view of the upper portion of the slideways. Fig. 2 is a similar view showing the slideways folded down and the wire-reel in position. Fig. 3 is a top plan view, and Fig. 4 :is a bottom plan view, of the frame of the machine. Fig. 5 is a section on the line a: fr, Fig. 1. Fig. 6 is a detail perspective view of the yoke. Fig. 7 is a detail view showing the connection between the slideways and supporting-bracket. Fig. 8 is a detail view of post-clamp and lever. Fig. 9 is a detail perspective view with parts removed and broken away.

In carrying the invention into practice I form a rectangular frame A of metal, which is secured to the front bolster of the runninggear of a wagon in any suitable or preferred manner. Bolted to the rear ends of the sides o o of the frame are the extensions or ears B B, in which are journaled the ends of the shaft of the winding or hoisting drum C. Suspended upon the drum-shaft at each end, so as to turn thereon, are the arms I) D, the lower ends of which are connected by the cross-piece d, bolted or otherwise secured thereto, and to this cross-piece, at or near the middle thereof,is swiveled the U -shaped piece cl2, to which is pivotally connected the frame E, to which are bolted the lower ends of the slideways F. It will thus be seen that the connection between the slideways and this support is in effect a universal joint7 from which it results that the slideways may be tilted forward, backward, or to either side for a purpose to bepresently explained. The slideways in the present construction are formed of four angle-irons ff, secured at the top to cross-pieces f f and at the lower end to the frame E, as described, and in the slideways reciprocates the weight G, adapted to strike the top of the post located between the ways and drive it into the ground. The weight is elevated by means of a rope g', passing over a pulley g2 at the top of the ways, and thence down to the winding or hoisting drum C.

Fast upon each end of the Vhoisting-drum shaft are the ratchet-wheels II, with the teeth of which engage the swinging pawls h, pivoted'between the bifurcated ends h of the ratchet-handles h2 when the handle is moved in the direction to wind up the rope, and pivoted to the side of the frame are the holdingpawls I, which also coperate with the teeth of the ratchet-wheels H to lock the windingdrum shaft to hold the weight at any point, as will be understood. When the weight has been raised to the proper height, it may be released by simply disengaging the pawls h from the teeth of the ratchet-wheel H on the drumshaft and giving the handle h2 a throw sufficient to carry it to the position shown in dotted lines in Fig. l, when the swinging pawl h will strike the pawl I and lift it out of engagement with the teeth of the ratchet-wheel H and the weight permitted to descend. In order that the post being driven may be held in position during the driving operation, a clamp J is provided moving in the slideways and adapted to fit over the post and to descend with the post as it is driven in the ground. This clamp consists of a square metal rim formed with slots or openings in opposite sides and with the iiangesjii. .In order that the clamp may be used on posts of different sizes, a lever K is passed through the openings in the sides of the clamp and held against the post, being held in position by means of pins k, passing through one of the series of holes ja, formed in the langesj2 on one side of the clamp and through a hole IOO 7c in the end of the lever, the other end of the lever abutting against the pin in the opposite flanges, all as shown in Fig. 8. The lever may, if desired, be formed with teeth k2 to still further insure the holding of the post.

Sliding on the sides of the slideways are the supports L, pointed at their lower ends, which are adapted to be driven into the ground to steady the slideways and` relieve the machine and wagon of strain, as will be readily understood.

In building fences on uneven ground and on hillsides it becomes necessary that the slideways be tilted sidewise or forward or backward, or that they be moved bodily from side to side in order that the weight may be caused to fall directly on the top of the post, and these various movements are accomplished by the following mechanism: To enable the slideways to be tilted backward and forward, there is secured to the slideways a brace or frame M, to which is swiveled a plate M', to the ends of which are pivoted braces M2 M2, which are pivotally connected at their opposite ends to a slide consisting of the upper and lower plates m m', embracing between their ends the side pieces a a, which latter constitute ways upon which the slide reciprocates and adapted to be held at any point of adjustment on the side piece by being clamped tightly thereon by means of the screw m2, as will be understood.

Mounted on the hoisting-drum shaft so as to turn thereon isa yoke N, formed of a metal plate bent to the form shown and in the upwardly-extending portion of which are formed slots n n, in which is adapted to slide a block a2, through which passes a screw threaded vshaft n2, whose ends are j ournaled in bearings in the braces M2 M2, one end of the shaft being provided with the crank-handle 01.4 for turning it.

In order to tilt the slideways backward or forward, it is only necessary to move the clamp-plates m m backward or forward along the side pieces of the frame and to clamp them tightly thereto when the desired inclination is reached. The tilting of the slideways to either side is accomplished by simply turning the screw-shaft n2 in the proper direction, as will be understood, the universaljoint connection between the slideways and their supports, before described, permitting these movements of the slideways.

To move the slideways bodily from side to side, the following mechanism is employed: Secured firmly on the rearbolster of the wagon is a plate 0, and to this plate, near the middie thereof, is bolted or otherwise secured an arm O', whose outer end carries a block O2, through which passes a screw-threaded rod O2, journaled in boxes O4, secured to the under side of the side pieces of the frame A, collars O5, fast on the shaft, being provided to prevent longitudinal movement thereof by reason of the collar O5 abutting against the boxes O4. On cach end the rod or shaft is provided with acrank-handle O, whereby the shaft may be turned. When now the shaft O2 is turned, being prevented from longitudinal movement by reason of the collar O5, as described, the side pieces a a and the parts carried thereby will be moved to either side, as will be understood.

When it is desired to fold the machine for transportation, the plate M, carried at the ends of the braces M2 M2, is released from the frame M, carried by the slideways, and the plates m m at the opposite ends of the braces M2 M2 loosened. The yoke N is then turned forward and down, the nut n2 sliding in the yoke, and the braces dropping down on the sides of the frame of the machine. The

/weight is then elevated and the slideways l*1 are then tilted forward and down on the frame, the posts or supports O7 receiving the ends of the slideways.

The side pieces of the main frame at the rear ends are preferably bent downward,v forming depending side pieces P, and to the lower end of the side pieces are hinged or pivoted the arms P, in the outer ends of which are formed openings for the reception of a wire-reel shaft P2, said openings being closed by means of pivoted latches p, which when closed about the reel-shaft will form with the arm P bearings for the shaft. Rigid upon this shaft are the friction disks or wheels P2, which are adapted to be brought into frictional contact with the wheels of the wagon upon which the device is mounted by means of the rods P4, which are formed with the hooked ends which take over the shaft, the opposite ends being screw threaded and passing through plates P5, secured to the plate O and being held in proper adjustment by means of the nut PG.

For reeling the wire when taking down wire fences the following mechanism is employed:

Journaled in the cross-piece Q of the frame A is a wheel or pulley Q, formed or provided on its under side with a crank-pin q, which is adapted to work in the slot q2 in the end of the bar Q2, which is pivoted at one end to the plate carried by the front bolster of the wagon. Carried by this bar Q2 is an arm or bar Q2, and upon this arm slides another arm Q10, carrying at its outer end the wire-guide Q31. Poweris communicated to the pulley or wheel Q from the reel-shaft by means of a belt or other flexible connection Q4, passing around the-pulley p2 on the reel-shaft.`

The operation will now be understood. The wire-reel having been placed on the end of the reel-shaft and the friction-wheels being brought in contact with the wheels of the wagon, as the wagon is drawn along the reelshaft will be caused to be revolved, thereby communicating motion to the wheel Q by means of the flexible connection, which wheel will be caused torevolve and in turning cause the bar Q2 to be reciprocated and the bar Q3 to be worked in and out, and consequently IOO IZO

laying the wire smoothly and evenly on the reel, as will be readily understood. The bar Q3 is pivotally connected to the bar Q2 and may be turned in under the frame when not in use. R, may be employed.

It will be noted that the machine is constructed throughout of metal, thereby insuring strength and lightness, and is admirably adapted for the purpose for which it is intended.
