FATEN' FFIGEQ PETER AHNIJUND, OF WEST UNITY, OHIO.

DITCHING- MACHINE.

SPECIFICATIQN forming part of Letters Patent No.322,771, dated July 21,1885.

Application filed April 7, 1884.

To all whom it may concern.-

Be it known that I, PETER AHNLUND, a citizen of the United States of America, residing at West Unity, in the county of WVilliams and State of Ohio, have invented certain new and useful Improvements in Ditching-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, reference being had to the accompanying drawings, and to letters or figures of reference marked there on, which form a part of this specification.

My invention relates to ditching-machines; and it consists in the improved construction and combination of parts hereinafter fully described and set forth.

In the accompanying drawings, forming part of this specification, Figure 1 is a side elevation of a ditching-machine constructed in accordance with my invention. Fig. 2is a plan view of Fig. 1. Fig. 3 is a longitudinal section. Fig. 4 is a front elevation, and Fig. 5 is a detailed perspective view of an attachment.

. The supporting-frame of the machine consists of side bars, A, connected together by means of bars 13. Arms 0 depend from the said supporting-frame, and are supported upon and secured to the axle D by means of metallic straps E, which embrace said axle D, as shown in Figs. 3 and at, and are secured to the front and rear sides of said arms 0.

Carrying-wheels F F are mounted upon the ends of the axle D, the wheel F turning loosely thereon, while the wheel F is keyed so as to turn therewith.

At the rear of the supporting-frame is located an excavator consisting of the side sections, G, which are curved at their upper portion, as shown in Figs. 1 and 3. Said sections G are connected together by shafts d and a vertical partition, 0. A link-belt, H, passes around said shafts (l, and is provided with a series of excavator-lmckets, f. A guard or shield, g, is provided at the rear of the curved portion of the excavator, and in proximity thereto is an inclined delivery-spout, I, which is centrally supported by an arm, it, while a connecting-rod, t, connects the rear of the de- (No model.)

livery-spout with the crank end j of the upper shaft, (1.

The lower extremities of the sides G of the excavator terminate in a shoe or scoop, J. The y said shoe J is connected by bolts k to the rear end of a longitudinal beam, K, arranged centrally, as seen in Figs. 3 and 4.. The said beam K is pivotally secured to the lower ends of vertical rods l J L by means of ears I and pivotbolts Z, the lower end of said vertical rods L L being enlarged and flattened to adapt them for such attachment.

The rod L plays vertically through a perforation therefor formed in a collar, M, coupled on the shaft D, the rod L playing through a perforated bloclg'M, supported by straps m depending from the front bar, B.

A whiffletree, N, is pivotally secured to the front portion of the block M.

The beam K has attached on its under side, near its forward end, a plate, m, which engages a bail, on, on the upper side of a stubbar, of, carrying a series of depending cutters or blades, on m The lower portions of the blades m m are turned inward, as shown most clearly in Fig. 4.

Astrap, m secured to the rear portion of the stub-bar m is secured to a yoke, m which embraces the beam K, and is held thereto by a pivotal connection, of.

A bar, m depending from the front portion of the beam K, carries a guide-roller, m at its lower end.

A gear-wheel, O, is keyed on the shaft D at one side of the center thereof.

An arm, 0, is centrally pivoted at the rear end of one of the side beams A and carries a stub-shaft, 0, at its lower end, upon which is mounted a pinion, o, and a sprocket-wheel 0 A connecting-rod, 0 connects the upper portion of the arm 0 with a lever, 0 pivoted at its lower end to the outer side of the beam A, and carrying a spring-pawl, 0 to engage with a segmental rack secured on the upper side of said beam A. The said spring-pawl 0* is manipulated by a thumb-plate, 0 secured to the lever 0 and operating in the usual manner to disengage the pawl.

A standard, 0, is secured at its lower end to the inner rear portion of the said beam A, and is perforated at or about the center for of a sprocket-wheel, O keyed on the end of lower shaft, d.

the, upper conveyer-shaft, cl, and around the sprocket-wheel 0". v

A shaft, 1?, is journaled centrally on the under side of the bars A, so as to playtransversely in bearings, and said shaft 1? has keyed thereon a pinion, p, and two drums, pp sep arated by a reduced portion, 12*.

A platform, P, arranged in proximity to the rear bar, B, has a slot through which extends the lower portion of a lever, P centrally pivoted by a pin, p passing through said lever and through bearing-blocks 1) secured on said platform. The lower end of said lever I is bit'urcatedto embrace the reduced portions 1). of the shaft P. A segmental rack, 11 secured on the upper side of the platform is adapted to engage a springpawl, 1), arranged on the lever 1), so as to lock said lever at any point of its pivotal movement.

Chains or cables q are connected, respect ively, to the rearend of the beam K and drum 1) and to the lower portion of the vertical rod L and drum p. Aratchet-wheel, r, is also mounted on the shaft 1?, and is adapted to have its teeth engage the bent end 1" of a springplate, It, secured at its forward endto the front bar, B.

A rock-shaft, S, parallel with the shaft P, is journaled in bearings on the under side of the bars A, and has extending therefrom an inclined pedal, 8, which 'is located immediately beneath the operators seat S. A projection or bail, s, on said shaft Sis adapted when said shaft S is rocked in its bearings to come in contact with the spring-plate R and lift the bent end out of engagement with the ratchet-wheel r.

The shoe J has arranged in its forward portion a section, t, which inclines toward the front of the shoe, as shown in Fig. 3, and terminates a short distance in advance of the sweep of the bucketsfas they pass around the A tongue, T, extends centrally from the front bar, B.

As the machine moves forward the cutters on m cut the earth to the extent of their depth, which earth is thrown inward and rearward by the bent lower portions of the said lower cutters. The shoe J, moving forward in line with the said cutting devices, theloose earth moves up the incline of the "section if and drops into the space in which the sweep of the buckets f occurs. The said buckets f take up the earth, and passing up the front side of the conveyer, carry'it over the upper shaft, d, after which they dump it into the in- By disengaging the pawl 0 of the lever 0 from the rack 0, and moving said lever forward, the lower end of the arm 0 can be moved rearward so as to effect the disengagement of the pinion 0 from the gear-wheel 0,

and consequently arrest the operation of the excavating-belt H. By moving the lever 19 upon its pivot so as to transversely shift the shaft P in its bearings and cause the pinion p to engage with the gear-wheel O the drums p 12 will be rapidly revolved, so that the cables 9 q will be wound on their respective drums, and exerting a traction upon the parts to which they are connected will slide the rods L L in their bearings and elevate the beam K, cutting devices, excavator, and shoe out of the ditch.

Fig. 5 illustrates a device designed to be connected at its respective ends to the lower extremities of the rods L L, in lieu of the beam K and appurtenances. The said device consists of a central bar, U, to the front end of which are pivotally connected bars U U A curved plate, u, is centrally connected to the bar U, so that the ends of said plate play through slots therefor in the bars U U". A series of perforations, u, in said plate permit a bolt to pass through the bars U U and engage the plate to lock the said bars in position thereon.

Each bar U U carries at its outer side a depending curved wing, U The ends of the wings maybe caused to approach each other by moving the bars U U on the plate a.

In operation the portion at which the bars U U are pivoted will constitute the rear of the device, and the wings U will operate to take the earth from either side of the ditch and more it into the same for the purpose of filling the ditch, the extent to which the earth is removed being dependent upon the adjustment of the bars U U on the plate u.

From the foregoing it will be apparent that a machine embodying my improvements is effective in operation and capable of performing the various operations incident to this class of machines, and is at all times under the complete control of the operator.
