United States Patent 3,256,229 TIE AND RAIL RAISING AND TAMPING MACHINE Ralph E. Keller, Kalamazoo, Mich, assignor to Kalamazoo Manufacturing Company, Kalamazoo, Mich. Filed Nov. 13, 1962, Ser. No. 237,126 13 Claims. (Cl. 104-7) This invention relates to a machine for raising the ties and rails of a railway track and tamping the ballast while the ties and rails are in raised position. My present invention is particularly desirable for, and has been embodied in, tie and rail raising and tamping machines such as is illustrated in my US. Patent 2,996,016, issued August 15, 1961, for tie and rail raising and tarnping machine.

The main objects of this invention are,

First, to provide a tie and rail raising and tamping machine which is highly eflicient, is strong and durable and at the same time is easily and quickly operated.

Second, to provide a machine embodying these advantages including a tie raising means which automatically adjusts to ties of varying lengths and degrees of solidity.

Third, to provide a machine having these advantages which is adapted for use in widely varying track conditions.

Objects relating to details and economies of the invention will appear from the description to follow. The invention is defined and pointed out in the claims.

A preferred embodiment of the invention is illustrated in the accompanying drawing, in which:

FIG. 1 is a fragmentary side elevational view of a tamiping machine embodying my invention, parts of the machine not directly related to my invention being omitted, the tamper unit being shown in raised position.

FIG. 2 is a fragmentary view illustrating structural detils of the tie and rail clamping jaws actuated to rail and tiev engaging position.

FIG. 3 is a fragmentary horizontal section on a line corresponding to lines 3-3 of FIG. 2.

FIG. 4 is an enlarged fragmentary view on a line corresponding to line 44 of FIG. 2.

FIG. 5 is a perspective view of the tie engaging unit bracket.

FIG. 6 is a diagrammatic view illustrating the coacting relation of the tie and rail engaging clamping jaws and the control means thereof.

FIG. 7 is an enlarged fragmentary elevational view of a modified form of a ballast engaging footpiece.

As stated, my present invention is an improvement upon, and is adapted to be embodied in, tamping machines of the type illustrated in my Patent 2,996,016, and therefore structural details of the complete tamping machine are not illustrated. Reference is made particularly to FIG. 1 of that patent as illustrating a tamping machine of the type which is desirable for use in my present invention.

In the accompanying drawing 1 represents ballast, 2 ties, and 3 the rails of a railway track. It will be understood that ballast varies as does the length of the ties and their degree of solidity, and the gauge of the rails may also vary in ditlerent tracks. The carriage, designated gene-rally by the numeral 4, is provided with wheels 5, the rear'wheels being commonly driven, and provided with manual control means for positioning the carriage relative to the ties to be tamped. A driving control lever is conventionally illustrated at 6. The carriage is provided with uprights 7 provided with braces 8 and having a cross piece 10 adjacent their upper ends.

The tamper unit, designated generally by the numeral 11, is mounted on the frame for vertical adjustment. The tamper units and adjusting means therefor are not fully ice illustrated, but they are desirably of the type illustrated in my said patent and also in the Jackson Patent 2,795,198,

issued June 11, 1957. The laterally spaced hydraulic jacks 12 are provided with a footpiece 13 adapted to engage the ballast between adjacent ties. The jacks are connected to this footpiece by the pins 14 engaging longitudinal slots 15 in the footpiece. This permits tilting and limited sliding movement of the iootpiece relative to the jacks.

The means for controlling the jacks are not illustrated, but it will be understood that the carriage is positioned so that the jacks may be lowered to engage the ballast between ties and that properly posit-ions the carriage for adjusting the tampers to and from tamping position. This also positions tie and rail engaging means relative to the tie to be t-amped. The tie and rail engaging means are engaged with the ties and rails prior to the actuation of the jacks. That combination, generally considered, is disclosed in my issued patent.

The tie engaging units, designated generally by the numeral 16, are duplicates and they are arranged in opposed aligned relation for engagement with the ends of a tie, see FIG. 3. Each unit includes an elongated tie engaging hook 17 having an inwardly facing jaw 18 engageable with the end of a tie, see FIG. 2.

The supporting brackets 19 include the laterally spaced plate-like member 20 fixedly connected by the crosshead 21 desirably integral therewith, as is illustrated in FIG. 4, and further connected by the struts 22, see FIG. 5. The portions 23 of these members 20 project outwardly from the frame and they are provided with parallel longitudinal slots 24 disposed transversely of the path of travel of the carriage. The cross-head portion 21 has an inwardly projecting socket 25, the purpose of which will appear as the description proceeds.

The tie engaging hook 17 is connected to the bracket member by means of a pivot 26 slidably disposed in the slots 24. Means are provided for yieldingly urging the hooks outwardly relative to their supporting brackets, this comprising thrust means, here a rod 27 having a yoke 28 at its outer end embracing the inner end of the jaw and engaged with the pivot 26. The spring 29 is arranged on the stem or rod 27 and extends into the spring supporting socket which is of such length that the jaw can be moved inwardly a substantial distance and into eifective clamping engagement with the end of the tie.

The jaw is actuated on its pivot and clampingly engaged with the end of the tie by hydraulic means comprising the cylinder 30 which is pivotally mounted at 31 on the bracket member and is provided with a plunger 32 and plunger rod, the plunger rod being pivotally connected to the jaw at 33 in downwardly spaced relation to its pivot 26. The cylinder is connected to a hydraulic source by the conduits 34, control means 35 for the two tie engaging jaw unit actuating means being indicated conventionally in FIG. 2. It will be understood that this may be manually or automatically controlled, details of the control means not being illustrated. It will be understood that it is timed with the positioning of the carriage and the actuation of the jacks, the tie engaging jaws being actuated to engaged position before the jacks are actuated.

The cooperating rail engaging units are duplicates and one is arranged to engage each rail. They comprise rail engaging jaws 36 which are pivotally mounted at 37 on the lower portion of vertically adjustable hangers 38 mounted at 39.

In the embodiment illustrated, the hangers 38 of the rail engaging hooks include upper sections 40 pivotally mounted at 39. The upper hanger members 40 have crosspieces 41 at their lower ends with which the threaded hanger'members 42 are connected by means of the nuts 43. These members 42 have slides 44 slidably engaged in the ways 45 provided therefor on the frame.

The jaw 36 is pivotally mounted on one of these slide members and is actuated to and from rail engaging position by hydraulic means comprising the cylinder 46 with a coacting plunger 47 provided with a plunger rod 4% which is pivotally connected at 49 to the rail engaging jaw, see FIG. 2. The cylinder 46 is provided with hydraulic connections 59 operatively connected to the control member designated generally by the numeral 51 which is connected to a hydraulic source.

In the diagrammatic view of FIG. 6, the

control valves

35 and 51 are conventionally illustrated in their relationship to a source of power 52. It will be understood that the

control valves

35 and 51 might be connected for simultaneous actuation to and from engaging position and in proper timed relation to the actuation of the jacks.

In the embodiment shown in FIG. 7, the tamper footpiece 53 is provided with an intermediate upwardly oifset portion. This footpiece is desirable for use where ballast may be .stacked up between the ties as sometimes occurs. The footpiece 13 is provided with an intermediate hanger loop 54- and the footpiece 53 with a hanger 55, the hanger means not being illustrated, but it will be understood that it is desirable to support the jack footpieces in upraised position when the tampin-g machine is not in use.

I haveillustrated and described my invention in high- 'ly practical and desirable embodiments thereof. I have not attempted to illustrate other embodiments or adaptations as it is believed that this disclosure will enable those skilled in the art to embody or adapt my invention as may be desired.
