nited States Patent RAILROAD TIE ADZING MACHINE Robert H. Abbott, Richmond, Va. Application December 14, 1953, Serial No. 397,927 3 Claims. (Cl. 144-133) This invention relates to means for conveniently replacing railroad ties and the principal object is to provide a machine whereby railroad ties can be adzed in such a manner as to eliminate the present practice of raising the track in order to remove and replace ties.

Another important object of the invention is to provide a machine which can be conveniently moved along a railroad trackway and which can be operated to adz the intermediate raised or humped portion of a tie and one end portion of the tie so that the tie can be easily withdrawn endwise without raising a rail.

A further object of the invention is to provide a machine wherein the adzing head is protected against contacts with the rails.

These and various other objects and advantages of the invention will become apparent to the reader of the following description.

in the drawings:

Figure 1 is a top plan view of the machine on a railway track with a portion broken away.

Figure 2 is a side elevational view of the machine on a railway track with the adzer head in working position.

Figure 3 is a section taken on line 3-3 of Figure 2.

Figure 4 is a fragmentary side elevational view of a modified form of the invention.

Figure 5 is a top plan view of the machine as shown modified in Figure 4.

Figure 6 is an enlarged sectional view taken on line 66 of Figure 5.

Figure 7 is a side elevational view of the stop means as shown in Figure 1.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 10 denotes a trackway, which includes a pair of parallel conventional rails 11, 11 supported by ties 12 and on which are the usual tie plates 13.

In carrying out the present invention a truck generally referred to by numeral 14 is constructed of a frame 15, through the forward and rearward ends of which axles 16 are journaled and on the ends of these axles are flanged wheels 17 to engage the track rails 11.

Elongated l-

beams

18, 18 are laid across the frame in parallel spaced relation as is shown in Figure 1 and these

beams

18, 18 are suitably secured to the truck frame 15.

The ends of the beams 18 are connected by

bridge members

19, 19.

Numeral 20 denotes a carriage which may be shifted along the beams 18. This carriage is provided with raised end portions 21, 21 and axles 22 are disposed through these end portions and are equipped with rollers 23 con fined between the adjacent flanges of the beams 18. Thus the carriage 20 is supported by the beams 18 and constrained to right-line movement.

Located in parallel spaced relation with respect to the beams 18 and disposed longitudinally thereof are a pair of bearings 23a, 23a welded or otherwise secured to the top side of the end portions 21, 21.

2,759,505 Patented Aug. 21, 1956 On one of the bridge members 19 is a pulley 24 and on the other bridge member 19 is a larger pulley 25 located on a shaft 26 which has a crank handle 27 at its upper end whereby the pulley 25 can be rotated.

A cable 28 is trained around the pulleys 24 and 25 and its ends are secured to the end portions of the carriage 20 so that by rotating the crank handle 27 clockwise the carriage 20 will be moved in one direction and when rotated counter-clockwise, the carriage 20 will be moved in the opposite direction.

Numeral 29 refers generally to a rockable frame which at a medial point is provided with a tube 30 welded or otherwise secured to its bottom side. This receives a pin 31, which may be a tube and this pin 31 is disposed through the bearings 23a and the tube 30 to rockably support the frame 29 on the carriage 20. The adzer frame 29 is not shown in Figure 1.

The forward portion of the frame 29 inclines as at 32 and then is extended obliquely as at 33. A bracket on this end portion of the frame 29 and denoted by numeral 34 carries a bearing 35 in which a vertical shaft 36 is journaled, this shaft extending downwardly and having a conventional adzer head 37 secured thereto. Extending from the bearing 35 is a strut 38 to which the lower portion of a vertical bar 39 is secured, this bar being also secured to the forward end of the frame 29. The upper end of the bar 39 is provided with a handle 40 whereby this end of the frame can be lifted or lowered to control the adzer head 37 with respect to a tie 12 being worked on.

'On the rear portion of the frame 29 and preferably counter-balancing the adzer frame assembly, is a power plant 41 driving a pulley 42, over which an endless drive belt 43 is trained. On the frame 29 is a bracket 44 supporting a pulley 45 and under this pulley one flight of the belt 43 is trained, as shown in Figure 2. On the upper end of the shaft 36 is a pulley 46 around which the belt 43 is trained and in this manner the shaft 36 and the adzer head 37 are driven.

When the forward end of the frame 29 is lifted by one man using the handle 40, a second man operating the crank 27 can shift the frame and carriage 20 to the desired position.

On one of the Lbeams 18 is located a stop structure and this includes an inverted U-shaped frame 47, which is shown in Figure 7. Threaded through the end members of frame 47 are

bolts

48, 49 whose heads 50 and 51 respectively serve as adjustable stops. The adjustments, when made, are fixed by jamb nuts 52.

Ties become bowed upward to some extent and tieplates are commonly set in seats which are shallow rebates cut in the tops of the ties. To facilitate withdrawal of a tie endwise and to minimize digging, the invention offers means to cutaway the major area of the top face of the tie. The part to be so cut away is shaded in Figure l. The stop structure 47, 5t 51 is designed tokeep the adzing head from engaging the track rail and tie plates during these operations.

The adzer head 37 will be lowered onto the tie 12 in close proximity to the tie plate (the one at the left in Figure 1), but not contacting the same. As a matter of fact it cannot contact this plate because of the presence of an upstanding stop-pin 53 on the adjacent I-beam 18. This pin 53 engages a portion of frame 29 to limit its motion to the left (with reference to Figure 1). The carriage 20 will then be gradually moved to the right with the 'adzing head cutting away the top of the tie 12 until this intermediate portion of the tie is cut down. The frame is stopped by the bumper 51 to prevent the adzer head 37 from contacting the tie plate to the right shown in Figure 1. At this point, the frame 29 can be lifted at its forward end and moved over the frame 47 and stops 50, 51 whereupon the head 37 may be again lowered to engage the right end of the tie 12. The head 37 can then be worked inwardly toward the outer end of the tie plate. It cannot engage the tie plate because of the presence of stop 50.

When the machine is not to be immediately used and is to be put in transit along the trackway, the rear end of the frame 29 can be lowered and the component parts 54, 55 of a conventional keeper engaged tohold the frame in this position with the adzer head 37 elevated.

Figures 4, and 6 disclose a slightly modified form of the invention. Reference character 14a generally refers to the wheeled truck. Numerals 18a, 18a denote I-beams extending across the truck 14a for movably supporting the carriage generally referred to by reference character 20a.

The adzer frame is denoted by reference character 29a and has a power plant 41a thereon corresponding to the power plant 41, The adzer head portion of the frame 29a is the same as the structure shown in Figure 2 and the drive means for the adzer head and shaft is the same.

The principal difference in the modification shown in Figure 4 over that shown in Figure 2 is the inclusion of controllable power-actuated means for driving the carriage, thus eliminating the need for a man to shift the carriage and permitting this machine to be operated by one man operating the forward end of the frame 29 with. the handle 40.

In carrying out the modified form of the invention, it can be seen that the power plant 41a drives a belt 60, which in turn drives a vane type hydraulic pump 61. This pump forces fluid under pressure to a valve bank 62, from whence it is directed selectively to a vane type hydraulic motor 63 secured to the carriage 20a. The motor 63 is in driving connection with a drum 64, around which is wound one flight of a cable 65, which is also trained over pulleys 66, 67 on the

end members

68, 68, which bridge the ends of the I-beams 18a, as shown in Figure 5.

A control line 68 extends from the hydraulic valve bank 62 so that the fluid while under pressure to the motor 63 can be reversed as desired, to cause the carriage 20a to be shifted reversely. Otherwise this modified form of the invention operates the same as the form shown in Figure 2 but is more labor saving.

While the foregoing description sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.
