PAUL A. GEISLER, OF MILWAUKEE, WISCONSIN.

MACHINE FOR DIGGING OUT RAILWAY-TIES.

Specification of Letters Patent.

Patented Jan. 8, 1918.

Application filed January 19, 1917. Serial No. 148,238.

To all whom it may concern Be it known that I, PAUL A. .GEISLER, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of lVisconsin, have invented certain new and useful Improvements in Machines for Digging Out Railway-Ties; and I do hereby declare that the following is a full, clear, and exact description thereof.

As the ties of a railway become unfit for further use, they are withdrawn and replaced by fresh ties. This continual withdrawal and replacement of ties entails a considerable expenditure of time and labor which is consumed mostly in digging up the track-way to permit withdrawal of the old ties. The replacement of the new ties occupies comparatively very little time.

It is therefore primarily the object of my invention to provide a machine adapted to dig up the track-way at the sides and ends ofone or a plurality of ties, whereby the tie may be slid transversely of the rails for withdrawal.

Inasmuch as it is necessary to dig between the rails and at the outer sides thereof, a more specific object of my invention is to provide a machine includin readily controlled digging members whic are vertically movable to rovide a clearance for the rails when moved therepast to the outer portions of the ties.

A further important object resides in the provision of such a machine which is adapted to travel on the railway rails whereby it may be most conveniently shifted for digging association with desired ties.

A still further important object resides in the rovision of a rail carried machine whic is Provided with means for anchoring it to the rails when in operation, whereby to prevent possible lifting movement of the machine upon engagement of the cutting members with relatively hard material.

I propose to employ a pair of digging members adapted for slidable engagement with the sides of a tie, and so formed as to be urged against the tie upon engagement with the ground in their digging operations. In connection with these digging members it is an object of my invention to provide an arrangement for spreading the digging members apart a distance greater than the width of the tie, whereby upon assuming an approrzimate operative position over the tie, sald dlgging members may be lowered and will automatically feed inwardly to proper engagement with the tie, thus facilitating their initial association therewith.

A still further object of my invention resides in the provision of a means for lifting the digging members, which is operable automatically upon movement of said digging members adjacent the rail, whereby to prevent their possible engagement with the rail, it being appreciated that it is desired to di as close to the rail as possible.

With the above and other objects and advantages in view, the invention resides more particularly in the novel combination, formation and arrangement of parts hereinafter described and pointed out in the appended claims.

In the drawings:

Figure 1 is a plan view of a tie digging machine constructed inaccordance with my invention.

Fig. 2 is a longitudinal sectional view through my machine on the line 2-2 of Fig. 1 and Fig. 3 is a transverse sectional view through the machine on the line 33 of Fig. 1.

Referring now more particularly to the accompanying drawings, the present embodiment of my machine comprises a body frame including the end sills 5 and side sills 6 which carry the transversely disposed axles 7 on which are mounted wheels 8 adapted to ride upon the rails 9 of the trackway. This body frame carries a plurality of transverse angle iron track rails 10 on which are mounted wheels 11 carried by a transversely shiftable frame including the .side sills l2 and transverse sills 13, said shiftable frame carrying the digging members and the operating means therefor.

The main drive shaft 14 of the machine is carried by the central portion of the shiftable frame, and for moving the frame, gears 15 are provided on the ends of the shaft and mesh with transverse racks 16 carried on the body frame. 'These gears are loosely mounted on the shafts and are en ageable by splined clutches, controlled by llnks 15 extending to a common centrally disposed control lever 15. This main shaft 14 has loosely mounted thereon a pair of pulleys 17 connected by straight and twisted belts 18 with the drive shaft of an engine 19, and a clutch member 20 controlled by an upstanding lever 21 is splined on the shaft for engagement with the pulleys 17 to impart selective reverse movements thereto. Thus the shiftable frame may be moved to either side of the track-way. For propelling the entire machine a transverse shaft 22 is carried by thebody frame at one end and is connected by sprocket chains 23 with one of the wheel axles 7. Splined, on this shaft 22 is a clutch 24 adapted for engagement with a gear wheel 24 loosely mounted on the shaft and held in mesh with, a beveled gear 25 on the main shaft 14, whereby the machine may be propelled from the main shaft in any desired shifted position of the shiftable frame by releasing the clutches of the shifting gears 15 and the clutch of the digging members hereinafter mentioned. The propelling clutch 24 is controlled byva lever 24 pivoted on the shiftable frame. Thus upon a digging operation in connection with one or more ties being completed, with the shiftable frame projecting at one side of the body frame, the machine may be propelled a short distance to start a fresh digging operation at the same side of the track-way where the first digging operation was completed, thus conducing to a considerable economy of time in operation.

The digging means carried by the shiftable frame comprises a pair of longitudinally extending shafts 26 and 27 journaled in the ends of series of hanger links 28 'which are journally connected with and extend downwardly and outwardly from the main drive shaft 14. These'digging shafts are driven by sprocket chains 29 trained about sprockets thereon and on a sleeve29 loose on the main shaft 14, this sleeve being engageable by a clutch 29 splined on the main shaft and controlled by an upstanding lever 29. Splined on the end portions of each of the shafts 26 and 27 are a pair of digging members comprising disks 30 at the outer sides of each of which is provided a radial series of tapered inclined blades 31 whereby upon rotative movement of the disks, the road bed material will be dug and laterally turned to-expose the sides of the tie. It is noted that by the tapered formation of the blades, the disks are automatically fed inwardly toward the tie and thus will snugly engage the tie in their digging movement longitudinally thereof. For raising and lowering each of the shafts 26 and 27 an upstanding lever 32 is pivoted to the shifta'ble frame and has a lateral arm 33 at its lower end connected by a link 34 with one of the shaft hanger links 28. A rack segment 35 is associated with the lever for coaction with a conventional gri operated pawl 36 thereon. Thus the sha s may be readily raised and lowered to adjust the digging members for association with different ties, and for clearance of the rails 9 in movement therepast.

It is noted that two pairs of digging memtie outwardlyv of the rail.

the knife blades 31 of the pairs are inclined in opposite directions. The digging .operatlon of the machine is started with one pair of cutting members' at the central portion of the trackway. The movable bed is then shifted inthe direction of cutting movement of the blades until-the cutting members are disposed adjacent the rails. The cutting members are then liftedto clear the rails and lowered to. dig at the sides of the The movable frame is then shifted backwardly and the other pair of cutting members operated to, dig the other side of the trackway. It is noted that the direction of cutting movement of the cutting members is such that the blades 11 present obtuse angles in conjunction with the body disk 30 whereby to procure a turning or plowing movement of the roadbed portion engaged thereby.

The cutting members are normally urged to a raised position by springs 37 on the shiftable frameconnected with the control levers, and to provide for an automatic release of the holding pawls 36 upon movement of the cutting members adjacent respective rails, an intermediately pivoted trigger lever 38 is carried by the shiftable frame immediately outwardly of the cutting members of each shaft 26 and 27 and this lever is connected with an upstanding pivoted lever 39 connected with a pivoted block 39 engageable with a corresponding pawl 36 for lifting said pawl and thus releasing the control lever to permit lifting operation of the corresponding spring 37. Thus the possibility of damage of the cutting members is prevented, although it is noted that in the present instance the blades 31 are disposed inwardly of the peripheral edges of the disks 30, and hence said disks would bear against the rail with very little damage. In some instances however, it may be desired to project the ends of the blades past the edges of the disks in an obvious manner to procure a more efficient cutting action.

When the pairs'of cutting members which are splined on the shafts 26 and 27 are raised, it is desired to spread said cutting members whereby to insure their disposition at the sides of the tie by engaging them with the ground outwardly of the tie and permitting them to feed inwardly by their natural ground engagement to a position engaging the sides ofthe rails. To accomplish this,each pair of cuttin members at one side of the machine has disposed therebetween a pair of straight intermediately pivoted crossed levers 40 and each pair of cutting members at the'o posite side of the frame have pivoted there mtween a pair of intermediately pivoted angle levers 41. The levers 40 and 41' of the transversely opposed airs of cutting members are connected by links 42 to thus produce in effect lazy tongs, which are connected and actuated by the longitudinally extending arm of an angle lever 43 which has a link 44 pivoted to its transversely extendin arm, this link 44 extending to the central portion of the machine for connection with a common control lever 45. Thus upon moving the links 44 inwardly, each of the pairs of cutting members will be simultaneously moved apart by the sliding engagement of the ends of the levers 40 and 41 disposed therebetween.

In the digging operation, engagement of the cutting members with relatively hard road-bed material might tend to lift theena tire machine from the rails, and to prevent this, anchoring hooks 46 are pivoted to the body frame and extend downwardly and outwardly thereof with their bill portions adapted to slidably engage under the outer portions of the balls of the rails, the inward inclination of the hooks being such as to prevent their slippage from interlocking relation with the rail. To afford a more positive sliding anchorage, inner hook members 47 may be also provided to engage under the inner portions of the rails, and each pair of said hook members may be connected by a hook 48.

The entire machine so far described may be thus most readily manipulated to dig or plow up the dirt at the sides of rails which it is desired to remove. To procure the longitudinal sliding movement of the ties, it is necessary for the ends of said ties to be exposed, and to dig a clearance at the ends of the rails, an end digging member .is provided including radial relatively wide blades 49 carried on a shaft 50 extending outwardly from one side of the shiftable frame and connected at its inner end by a universal coupling 51 with a shaft 52 journaled on the shiftable frame and connected by bevel gears 53 and a clutch 53 with the main drive shaft 14. Movement of this digging memher is controlled by an upstanding control lever 54 having a lateral arm 55 thereon connected by a link 56 with a collar 57 journaled on the shaft 50, said shaft being held against horizontal pivotal movement by guide plates 58. In some types of roadbeds wherein the bed inclines downwardly from the outer ends ofthe rails, relatively little digging is required, but under conditions where the road-bed lies flush with the surrounding ground a relatively long cut may be procured by shifting the carrying frame, to provide a suflicient clearance to withdraw the rails.

Although I have shown the power unit of my machine as comprising an internal combustion engine 19, it is obvious that any power means may be provided, and in tie replacing operations on the road-beds of electric railroads, a considerable economy Wlll be procured by utilizing an electric motor which may receive its power from a suitable trolley carried preferablyby the body frame.

Althou h Iha've shown cutting members adapted for association only with two ties, it is obvious that sets of cutting members may be employed for any number of ties, slnce should it be only desired to dig out a single tie the remaining cutting members may be retained in their lifted inoperative position. It is also obvious that to meet difi'eringconditions of use, various changes and modifications of structure may be resorted to, without departing in any manner from the spirit of my invention, and it is therefore to be understood that the scope of the invention is limited only by the scope of the appended claims.
