DITCHING AND EXCAVATING MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 421,122, dated February 11, 1890.

Application filed April 5, 1889- Serial No. 306,098. (No model.)

To all whom it may concern.-

Be it known that I, HENRY CARTER, a subject of the Queen of Great Britain, residing at Albion, in the county of Orleans and State of New York, have invented a new and useful Improvement in Ditching and Excavating Machines, of which the following is a full, clear, and exact description.

My invention relates to an improvement in machines for cutting and clearing or excavating ditches or trenches, and more particularly to that class of ditchers which operate by means of a plow or share and having a large elevating-wheel fitted with scoops to lift and discharge the soil.

The object of the invention is to so improve the construction of the machine for which Letters Patent were granted to myself June 28, 1887, and numbered 365,580, that the machine will be more compact, effective in op eration and durable, and capable of being manufactured at a less cost.

The invention consists in the novel construction and operation of the several parts, as Will be hereinafter more fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters and figures of reference indicate corresponding parts in all the views.

Figure 1 is a plan view of the machine. Fig. 2 is a side elevation with one of the guide-wheels removed. Fig. 3 is a rear elevation. Fig. 4: is a vertical section taken near the center of the machine. Fig. 5 is a vertical section through a portion of the dumping shear-plate and elevating-wheel, illustrating a bucket being dumped. Fig. 6 is a similar view illustrating the mechanism for restoring the bucket to its normal position.

Fig. 7 is a side elevation of a bucket and a partial side elevation of the wheel. Fig. 8 is a perspective view of a bucket detached. Fig. 9 is a plan view of a portion of the elevating or bucket wheel, illustrating the application to the bucket-spindles of a springbrake adapted to retain the buckets normally in a receiving position. Fig. 10 is a longitudinal section on line 10 10 of Fig. 9. Fig. 11 is a sectional detail View illustrating the means employed for raising and lowering the plowshare. Fig. 12 is a vertical section through the plowshare-support. Fig. 13 is a plan view of the support, and Fig. 14 is a perspective view of the plowshare detached. Fig. 15 is a transverse vertical section on line 15 15 of Fig. 2, and Fig. 16 is a partial side elevation of the tongue and a vertical section through the tongue-clevis and adjusting device. Fig. 17 is a plan View of the friction trip-roller and'bearing for the same. Figs. 18 and 19 are side elevations of the standards in which the share-manipulating mechanism illustrated in Fig. 11 is journaled.

In carrying out the invention the frame of the machine consists of an essentially perpendicular arch 20, in the lower end of which the elevating or bucket wheel 21 is journaled, the periphery of the wheel at one or both sides being provided with an inwardly-extending flange 22 at a right angle to the tire. At or near the center of the arch, at each side, a beam or bar 23 is rigidly secured in any approved manner, which frame beams or bars extend horizontally in parallel lines forward and to the rear of the elevating or bucket wheel, as shown in Figs. 1 and 2.

Between the lower extremity of the arch and the frame beams or bars 23 the inner ends of two lower frame bars or beams 25 are secured to said arch, and the said lower bars or beams 25 extend in nearly parallel lines rearwardand upward to a contact with the extremity'of the main horizontal frame beams or bars, beingattached thereto, and

upward to support and sustain a seat 26.

Upon one side of the machinethe left, for instance-a segmental plate 27 is secured at its ends to one of the mainhorizontal framebeams 23 in such manner that the said plate will conform to the curvature of the elevating or bucket wheel and extend independent of said wheel from its periphery a distance upward therefrom, practically constituting a fender. This fender is likewise secured to the inner face of the arch. Upon the opposite or right-hand side of the machine ashort segmental fender-plate 28 is firmly fastened to the right-hand frame beam or bar 23 between its center and its rear extremity, and to the arch 20 between its center and its upper end, as best shown in Fig. 2.

Upon the right-hand side of the machine one end of a curved fender-plate 29 is firmly attached to the main frame beam or bar 23, horizontally aligning the equivalent end of the left-hand fender 27. The other end of the right-hand curved fender 29 is carried diagonally over and above the elevating-wheel in direction of the rear of the machine, practically to a contact with the inner face of the lefthand fender 27, as best shown in Figs. 1 and 2.

The object of the curved fender 29 is to conduct the dirt carried upward by the elevating-wheel to one side of the ditch and act as a dumping or shear plate. To this end a chute 30 is hinged to the yoke 20, and the fender and said chute are capable of vertical movement.

The hinge attachment of the chute is effeeted by projecting an arm 31 from the outer face of the fenderbeyond the edge of the ele vatingwheel, as shown in Fig. 2, and carrying one end of the chute to a pivotal contact with the forward face of said arm, the other end of the chute being notched to receive the forward edge of the fender. By reason of this hinged connection of the chute with the frame of the machine the elevati ng-wheel may work effectually in a very deep ditch, and should the chute strike the bank it will automatically accommodate itself thereto and continue to effectively deliver the dirt a proper distance from the edge of the ditch. \Vhen the machine is withdrawn from the ditch, the chute drops to its normal position.

The tongue 32 is hinged or pivoted between the forward ends of the main side bars 23 of the frame, and a guard-rail is secured to the left-hand member of the arch 20 at its stop, .which guard-rail, extending over and following the curved line of the fender 29, is attached to the forward extremity of the corresponding portion of the righthand frame bar or beam 23, as shown in Fig. 2. A space intervenes the guard-rail and the upper edge of the fender 29, through which the buckets of the elevating-wheel travel.

A series of buckets 34. (illustrated in detail in Fig. 8) are pivoted to or journaled in the left-hand flange 22 of the elevating-wheel, the said buckets being ordinarily arranged around the entire periphery of the wheel about twelve to fourteen inches apart. The buckets consist of a body portion A, preferably rectangular in cross-section, from one end of which ablade A is projected at a right angle outward, the under or bottom edge of the blade and the corresponding edge of the body being preferably beveled to constitute a cutting-edge. The end of the body opposite to that carrying the blade A is ordinarily rounded off at its bottom edge, as shown at a in Fig. 8, an d carried essentially perpendicularly upward to form a wing or arm A of less width than the body.

The upper extremity of the arm or wing A is bent horizontally inward parallel with the blade, whereby a lug a is produced, and the outer edge of the arm or wing is curved, as best shown at a in Fig. 8, by producing a concavity at or near its center. The construction of the bucket is completed by attaching a pintle or post 35 to one face of the body near its curved end, which pintle extends horizontally outward parallel with the blade A.

Atproper intervals upon the inner face of the periphery of the elevating-wheel bearings 36 are secured, preferably tubular, for the reception of the posts or pintles of the buckets, as shown in Figs. 9 and 10. The bearings 36 abut at one end against the left-hand elevating-wheel-flange, but do not extend entirely across the periphery of the wheel, being stopped slightly beyond its center, as shown in Fig. 9. The pintles of the buckets are passed through suitable apertures in the said left-hand-wheel flange into the several bearings 36 and project beyond the latter, having secured upon their projecting ends sleeves 37, as shown in Fig. 10, preferably provided with a roughened exterior surface.

hen the buckets are attached to the elevating-wheel and are in position for entering the earth, the upper edge of the blade bears against the outer peripheral surface of ihe wheel, and the arms or wings extend upward in direction of the rear of the machine, as best illustrated in Fig. 2.

The revolution of the buckets is controlled by spring-brakes 38, (best illustrated in Fig. 10,) one brake being adapted to exert tension upon two opposed bucket pintles or shafts. The brake consists of a spring-bar B, of suitable length, curved upward at its center, and two brake-shoes B, in the backs of which the respective ends of the spring-bar are inserted, the front face of the shoes being concaved for contact with the bucket-sleeves 37, and when said sleeves are roughened the concave face of the shoes is treated in similar manner. One end of the spring-bar B of the brake is threaded and provided with a locknut B whereby more or less tension may be extended upon the pintles or shafts of the buckets to cause them to revolve tightly or loosely in their bearings, as occasion may demand. The sleeves 37 not only serve to provide an increased contact-surface for the brake-shoes, but also retain the bucket pintles or shafts intheir bearings.

From the inner face of the left-hand frame side bar 23, preferably directly forward of the yoke 20, a pin 30 is horizontally project-ed, and forward of and above the pin a frictionroller 40 is journaled upon the upper edge of said side bar, as best shown in Fig. 5. The friction-roller 4:0 is properly journaled in a horizontal bearing-sleeve 41, secured to the frame side bar 23 and projecting a distance outward therefrom, as shown in Fig. 17, the shaft or spindle 42 of the wheel being made to extend beyond the outer face of the sleeve, which projecting end is threaded and pro- This long bearing vided with a lock-nut 43.

IIO

of the friction-roller considerably lessens the friction, and thereby renders the shaft or spindle less liable to wear.

Between the forward end of the right-hand fender 27 and the dumping or shear plate 29 a pipe-roller 44 is journaled. In the action of the elevating-wheel after the buckets have received their load they are carried upward by the said wheel until the curved edge of the bucket wing or arm A is brought in contact with the pin 39, whereupon as the elevating-wheel moves forward the blade of the bucket is elevated, the said arm or wing traveling over the friction-roller 40 until when opposite the rear end of the delivery-chute, where the bucket blade is at its greatest height, the load carried thereby is impinged upon the shearpla'te 29, from whence it falls upon the delivery-chute.

The lug a limits the upward throw of the buckets, and the curve in the wing or arm of said buckets permits the blade to be carried very near the delivery-chute before the load is dumped. This movement of the buckets is illustrated in Figs. 5 and 7. The blades of the buckets in their forward and downward travel pass between the shear-plate 29 and the upper guard-rail, the latter serving somewhat to clean them, and also to guide large clots of dirt down to the chute. When the blades strike the pipe-roller 44, they are restored to their normal or receiving position, and in this position pass downward to take another load.

The plow-standards 45 are projected rearward and downward from the yoke 20, being pivoted thereto, or to a block secured to the yoke, one at each side of the elevating-wheel, and the shoe 46 of the plowshare, to which the lower ends of the said standards are attached, is preferably east in one piece, as shown in Figs. 12 and 13.

The plow-shoe consists of a curved inclined base-wall D,held between two side pieces D, having vertical recesses cl produced in their outer faces, in which the lower end of the plow-standards are inserted, as shown in Fig. 2. The side pieces D have a rear extension d, between which the lower end of a" segmental rack 47 is pivoted, the said rack having its teeth produced upon its outer face. The rack is projected upward through the side bars of the frame to the rear of the elevating-wheel, and is operated to raise and lower the plow-shoe in a manner hereinafter set forth. The right-hand side piece of the plow-shoe is provided with a mold-board 48, to aid in packing the dirt in the buckets as they pass over the shoe in their upward movement, which mold-board is best shown in Figs. 2 and 14. The lower end of the basewall D of the plow-shoe projects beyond the side pieces, and is provided upon its upper face at this point with a diagonal recess (Z the lower extremity of said wall being also diagonal, as shown in Fig. 13. In this recess the plowshare 48 is secured. (Illustrated in detail in Fig. 14.) As a matter of economy and cheapness, the plowshare 48 is made in two pieces E and E. The section E, being the main portion or body of the share, is secured in the recess (1 by a bolt,

A throat is formed at the rear of the ma chine to retain the material lifted by the buckets in the same when in a horizontal position.

The throat consists of two side pieces 49, curved to the radius of the elevating-wheel and secured to the plow-standards at one end, the

upper ends of the side pieces 49 meeting the fenders 27 and 28, as best shown in Fig. 2, in which one side piece is omitted to illustrate more clearly the construction of the throat. The back of the throat consists of a curved preferably longitudinally slotted plate 50, extending downward to the rear of and a free contact with the shoe of the plowshare. This back plate is suspended by two spring-hangers 51, secured to its rear at the bottom-one at each sidethe upper ends of said springhangers being firmly attached to a bar 52, held transversely in the main side bars of the frame. The back plate 50 of the throat is further acted upon by a spring 53, secured to the forward face of the rack-bar 47.

It will be observed from the foregoing description that the back of the throatis springactuated, rendering it capable of yielding to permit the upward passage of large bowlders and similar articles. It will be further observed that as the plowis capable of telescoping upon the spring-back of the throat ample clearance is obtained when needed for the passage of stones, and the plow-shoe in its movement effectually cleans the throat.

The smooth or forward face of the rack 47, utililized in raising or lowering the plow, is made to engage withafriction-roller 54, journaled in the frame at the rear of the elevating-wheel, and the forward or toothed face is made to mesh with a pinion 55, fast to a shaft 56, also journaled in the frame, which shaft also carries a bevel-gear 57, meshing with-a horizontal beveled pinion 58, secured to the lower extremity of a perpendicular shaft 59, provided at its upper end with a hand-wheel 60, convenient to the drivers seat. The shafts 56 and 59 are journaled in perpendicular opposed hangers 60 and 61, of peculiar construction. (Illustrated in detail in Figs. 18 and 19.) The hangers are secured to the frame of the machine, the hanger 60 being provided with. a vertical integral sleeve 62 upon its inner face, in which the perpendicular shaft 59 is journaled, and a collar 63, integral with the sleeve in which one end of the shaft 56 has a bearing, the other end of this shaft having a bearing in a similar collar 64:, formed upon the hanger 61, as shown in Fig. 19. The two hangers are also provided with collars or apertures (35 at their upper end to journal a treadle-shaft 66, the treadles 67 whereof are secured to the extremities of the shaft for engagement by the drivers feet. Upon this treadle-shaft a pawl 68 is fixed, capable of contact with the pinion meshing with the rack 47, as shown in Figs. 1 and 11. The tongue is pivoted between the forward ends of the main side bars 23 of the frame, and upon said side bars a bail 70 is secured, through which a threaded bolt 71 is passed, having a reduced lower end adapted to enter anaperture in a second bail 7'2,fast to the inner end of the tongue, at its upper face. Thus it will be observed that by raising or lowering the bolt 71 the tongue may be raised or lowered and the line of draft thereby changed. This construction is fully illustrated in Figs. 15 and 16. A curved essentially rectangular clevis 73 is entered over the tongue directly in front of the bail 72, which retains it upon the tongue, and to thebottom bar of the clevis, at its center, the whiffletree 7 Jris pivoted. Beneath the whiflietree an evener '75 is fulcrumed, and the ends of the eve ner are attached to links '76, pivoted at one end to the plow-standards, below their center, by chains 77, whereby it will be seen that the draft is directly upon the plow. By providing the tongue with a clevis, as above described, the tongue may be made .much shorter, and the clevis is free to slide back and forth. A perpendicular arch or clevis 78 is fulcrumcd, at or near the center of its members, upon the frame-arch 20, at or near the top of the latter.

"he machine is guided in its work in a ditch, and yet permitted to have ample vertical movement or incline to the front or the rear, by means of an essentially U-shaped carriage 7f), grooved to slide over the pivoted arch or clevis 7 S and provided with frictionrollers 80 in the groove for contact withthe edges of the clevis to relieve friction, as illustrated in Figs. 3 and 4:. From the lower end of each member of the carriage an axle S1 is projected, which is preferably given a slight downward inclination and braced by stayrods 82 in any approved manner. Each axle is provided with a wheel 83, adapted to travel upon the surface of the ground, and when the carriage is applied to the machine the axles at their intersection with the stay-rods 82 are connected with the forward ends of the side bars 23 of the frame by detachable rods 84.
