BENJAMIN BOWMAN, OF $PRINGFIELD, MISSOURI DITCHING-MACHINE- Application filed October 25, 1909. Serial No. 524,409.

To all whom it may concern:

.Be It known that I. BENJAMIN BOWMAN,

State of Missouri, have invented certain new and .useful Improvements in Ditching. Machines; and I do declare the following to be a full, clear, and exact description oft-he invention, such as will enable others skilled in the art to which it appertains to make and use the same. I

This invention relates to improvements in ditching machines. One object of the invention is to provide. a machine of this character having arranged thereon a pneumatic hoisting and dumping mechanism, the air foractuating which is under control of suitable valves whichmay be operated by one man. Another object is to provide a ditching machinehaving means for the attachment and operation of various implements employed in connection with ditching opera'- the appended claims.

HElSSUED vided with. suitable supporting wheels 2. Arranged. on the platform 1, near the center ,of the same, are upright derrick frames 3, on each side of which are plvotally mounted cranes 4, 1n the boom of. which are mounted 'guide pulleys 5 around which are passed hoist ng chains 6. The derrick frames 3 are spaced a suitable distance apart and are connected together at their upperv ends by a longitudinally disposed brace bar 7 and are further braced by guy rods 8 connected thereto'and to the platform of the car.

are; mounted guide pulleys 9 over which the hoisting chains 6 pass, saidchains passg' hrough the bars 7 around th ll 10 on the pper ends of piston rods 11 which On the upper endsof the derrick frames are provided with pistons 12. .The piston rods 11 and pistons l2 operate in hoisting endsv of the cylinders and have connected thereto chains 17 which pass over guide pul-- leys 18 which are arranged onthe derrickframes, as shown.

by the pressure of aironthe'pistons in the 1 are adapted tion with the ditching operations and which Locatedfat any 'suita le -position on'oi'be neat-h the platforin- 1 are compressed air storage tanks or reservoirs 2t), said tanks being here shown as arranged on the plat-' form, adjacent toone end thereof. .Cion- .nected with- .the reservoirs or tanks are suit.-

able air compressing pumps ,21 of which be connected to the'boiler of the locomotive The chains 17 pass around pulleys 19 on the upper ends ofth'e piston rods 16 and are suitably secured at. their inner'ends whereby they are operated employed in propelling the machine by a suitable steam supply pi 1e 22, as shown in the drawings. T he compressed air from the tanks or reservoirs is conducted to the upper and lower ends of the hoisting and dumping cylinders by suitably arranged air conducting pipes 23, in'wlnch are arranged cut-01f valves 2% and four-way controlling connected at their opposite ends to the ditch valves 25, said valves being arranged in a group and at a suitable location on the machine, within convenient reach of a single operator who will thus be enabled to readily control the operation of the hoisting and" dumping mechanism on both sides of the machine. I

'Pivoted insuitable bearing brackets on opposite sides of the platform of the ,machine, adjacent to one end. thereof and adapted to be swung outwardly and inwardly to operative and inoperative positions, aredraft beamsv 26 having formed therein a series of bolt holes 2 7 toreceive bolts to which are adjustab ly connected draft chains which are connected with the; implements operated by the machine. The. draft beams are connected at their outer ends to the ends of the platform 1 by draft rods 28 and the outer ends of the draft beams are supported by draft supporting rods 29 which extend upwardly and inwardly and are connected at their innerends to beam supporting frames 30 arranged across the platform of.the machine, as

shown. When not use, the draft rods 28. are disconnected from the outer ends of the draft beams 26 and said beams are then folded inwardly alongside the machine to an out of'the way'position. lVhen in use, the beams 26 project laterally from'one or both sides of the machine and to the bolts in the bolt holes 27 in the beams are connected draft rods or 'chains'31 which are forming devices.

In the ditching operations, Tare em iloyed a number of implements or devlces actuated by the machine and among which are scoops] 32, to theopposite sides of WhlCll, ad acent -to-their upper edges are connected bails 33- towhich are secured the-outer ends ofthe hoisting chains 6, which'pass over the guide pulleys in the cranes 4 and derriclrframes and under pulleys 10 on the-piston rods 11 of the pistons in the hoisting cylinders'13 and are secured at-their inner ends to the derrick frames whereby when said pistonsare forced downwardly by the air let into'. the upper ends of the cylinders, a pull is exerted on the chains and said scoops will be hoisted. To the rear ends of the scoops are connected the outer ends of'the dumping chains 17 which pass over the "guide. pulleys 18 in the derrick frames 3 and cranes'4 and under thepulleys 19 on the piston rods 16 of the pistons 15 in the dumping cylinders 1.4, whereby when air is let into the upper ends of said cylinders 1st, after the scoops have been hoisted, a pull will be exerted on the chain 17 and the rear cnds of the scoops will be elevated and at the same time air is released from, the hoist ing cylinders to permit the forward ends of the scoopsto lower thereby dumping the same. When the scoops are lowered to an operative position, the forward .endsof the same are connected by draft chains 31 to the bolts in the bolt holes27' of the draft beams whereby said scoops are drawn along the ditch and are thus loaded. i

In addition to the scoops, I provide plows 34- which are held out at the desired distanc'e from one or both sides of the machine by connecting bars 35. (See Fig. 3.) The bars 35 are eachpreferablyconstructed of tubular telescoping sections, whereby the bar may be lengthened or shortencdto hold the {plow at the desired distance from the side of the machine. The telescoping sections bar 35'is connected in any suitable manner to the beamof the plow, The plow beam is'connected at its forward end to a draft cable 37 the for'ward end of which is. fas

.tened to a suitable connection on one side of the machine, as shown clearly in Fig. 3,

whereby each plow is drawn through the ditch. On the rear end of the plow beam 1s arranged an upwardly pro ecting arm or standard 38, to which is connected the outer end. of a steering bar 39 which is formed in adjustaby connected telescoping sections similar-to the bar 35 and which is connested-at its inner end to the piston rod l0 of a piston 41 operable in a horizontally disposed air cylinder 42, one of which is arranged on each side of and beneath the platform of the "machine, adjacent to the endthcreof, as shown in Fig.

'3.- The cylinders 42 are connected by suitable airconducting pipes 43 to the compressed air-reservoirs 20 and in said pipes are arranged controlling valv'es whereby the air is admitted to. the cylinders and exhausted therefrom to operate the pistons and thereby retract or project the steering rod'39 which will move the rear end of the plow beam in the desired direction forstcering the plow alongthe ditch. To the forward end of tho plow beam is connected the outerend of one of the hoisting chains 6 whereby said end of: the plow beam and the plow .point may roosioaa and flaring out-wardly toward their upper and reaijl edges, as shown. The forward edge of tl'ielfsl'oper is provided with a cutting blade 46 which engages and loosens the earth formingth'e sides of the ditch and permit the curvedjside plates of the slqper to grade i The outer ends of on the inner side plate 45 down or incline the sides ofthe ditch. The sloper is held in position at the desired distance beyond the. side of the machine. by the connecting bar 35, which also forms. the connection for the plow, as previously described; In additionto the bar 35, I also preferably employ an additional bar 47 (see Fig. 5) which is constructed in a similar manner to the bar 35 and is connected at its inner end to one arm of the bracket 36 above the bar 35, said bracket being provided with two pairs of connecting lugs or arms arranged in vertically spaced relation and diverging-as shown 1n Figs. 3 and 5. the bars 35 and 47 are connected to bearing lugs or cars of the sloper.- The sloper has connected to the opposite ends of its forward edge, a draft chain 48 which is engaged. by a draft pulley 49, said pulley being connected to the draft cable 37 of the plow, whereby the bank sloper is drawn along theditch. The bank sloper is supsuitably ported inoperative position by the hoisting cables 6 to the outer end of which it is connected in any suitable manner.

Pivotally connected at their forward ends to suitable bearing brackets 50 arranged on the'oppo site sidesof the platform 1, adjacent to the brackets 36, are dirt. spreading or scraping blades 51 which are adapted to be swung inwardly and outwardly from the sides of the machine at any desired angle to scrape or spread the dirt, adjacent the opposite sides of the machine (see Figs. 1 and 7).. The dirt spreading blades 51 are held at the desired angle at the sides of the ma China by brace rods 52 which'are preferably formed in adjustably connected telescoping sections whereby the bars may be lengthened or shortened to hold the blades at the desired angle. The inner ends of the. bars 52 are pivotally connecved to suitable brackets on the underside of the platform 1 and at their outer ends are pivotally connected to "the inner sides ofthe blades. The forward ends of the blades 51 are pivotally connected to the bearing brackets 50 in such manner that the blades may be lowered and raised to operative'and inoperative positions, said blades being preferably so connected by together at their forward and lower edgesthe latter may be swung hangers 55 to the underside "side of the operatin various lmplements used in connection with blades 51 to permit the blades to be moved vertically (see'Fig. 12). The bladesare lowered and raised by hoisting chains 6 whiclrare connected at their lower endsthereto in any suitable manner. By disconnecting the', brace bars 52'from the blades, back against the sides of the machineto an inoperative and out of the way position. The lower ends of the bearing brackets 50 to which the forward ends of the scrapingbladesLare connected, are braced by chains or 'rods 53 which connect said lower ends of the brackets to the end of theplatform, as shown.

In addition'to the various ditching and grading devices herein described, I provide on each side of the machine small spreading or scraping plows, comprising blades or plates 54 which are hingedly connected by of the machine. The blades 54 are disposed at a suitable angle and when in operative position are connected to draft chains 56 which are secured at their'opposite ends to the frame of the machine. These scraping plows are provided to scrape olf'from the ends of the ties and the ballast outside the railway rails, any dirt which may have fallen thereon. When not. vin use the blades 54 may be folded up under the platform of the machine and held in any suitable manner.

Suflieient space is provided on the platform 1 of the machine between and on each cylinders to receive the the machine when the implements are not in service andsuitable boxes or receptacles are provided to receive the various bracing and operating bars and rods used in connection with the operation of the machine.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

' Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention, as defined in the appended claims.
