The device .for moving freight cars and the like along railroad tracks as. embodied in Figures 1, 2, 3 and 4 comprises a main frame F which may be-produced as. one integral unitor may be com- 2, Claims. (Cl. 105-141) posed of: several structural parts It has two longitudinal side walls i0 and-ll respectively; extending parallel to each other. .The forward end portions I2 and 13 respectively of said side walls extend outwardly at-an angle of approximately 60 degrees to each other and-upwardlyatan: 0-btuse angle to the. main portion of the side walls. On the" forward end of each forward side wall portion. 12 and i3 afront wall 'l4w'andl5,lrespectively, isv formed and. extends inwardly from the corresponding side wall portion at a right angle thereto. Between the inner edges of the twofront walls f4 and it. an opening. is left, which is large enough to permit a portion of a railroad car wheel H5 to. enter.

on the inner end of eaohforward side wall portion [2: and l'3an. intermediate wall I! and l8respectively is. formed'and extends inwardly from and at a right angle :to the adjacent forward side wait portionand'parallel to. the. front. wall H or 5. The intermediate walls are permanently'comnected with each other in the vertical longitudinal center plane of the main frame F.

Substantially Z-shaped brackets 119 and 20' respect'ivel y are secured to the inside face and adjacent to the rear end of the side walls 10 and H respectively'so that the

webs

21 and 22 respectively of said brackets extend toward each other and that'the

inner flanges

23 and 24 of said brackets are spaced fromv eachother and extend downward-1y parallel to each other. An axle 25 extends between thefiange23 and 24 and is rotatably'supported by them. On the central portion of the axle 25 a small roller 26. is rigidly mounted and is provided with annularend flanges 21.

A'reinforcing bar 238' is. welded or otherwise secured atiits rear end portion to the undersides of the side wall In and the intermediate wall I! and extends forwardly, outwardly and upwardly therefrom. The forward end portion of said bar is welded or otherwise fastened on the underside of the front wall H. A similar reinforcingbar 2:9. is secured at its rear end portion to the under-- sides of the side wall I l and the intermediate wall I58 at itsfron-t end portion to the underside of the front wall ['5 A bracket 39"has an upper flange 31' with whic it is: weldedor otherwise secured to the inside surface of the reinforcing bar 28 intermediate the ends thereof. From the upper flange 3la web 32 extends downwardly and inwardly and on the lower end of the web 32 a downwardly extending lower flange '33 is formed. A similarly shaped. second bracket 34 is secured with its upper flange 35 'to the inside surface of the reinforcingbar' 3 29 oppositely from the bracket 36. A web 36 extends downwardly and inwardly from the upper flange and a lower flange 31 projects downwardly from said web 36.

A shaft 38 extends through and is rotatably supported by the two

lower flanges

33 and 31, and projects laterally beyond one of the side walls, for instance the side wall I6.

A roller 39 is rigidly mounted on the shaft 38 between the

lower flanges

33 and 31. The roller has a cylindrical middle portion 40 from which conical flanges M and 42 respectively extend. On

the circumferential surfaces of the two flanges" are provided longitudinally running sharp projections or teeth 43 and 44 respectively which are adapted to engage the head of a track rail 45.

The small roller 26 rests rotatably onthehead of the rail 45 and the relative dimensions of said small roller and of the roller 39 are such 48 between the front wall I5 and the intermediate On therear end portions of the shafts 46 and 48'respecti'vely meshing bevel gears 58 and 5| respectively are rigidly mounted and are located ad- J'acent to the rear surfaces of the intermediate walls-l1 and I8 respectively. A drive shaft 52 extends transversely through the main frame F and is rotatably supported in the side walls I 0 and II of the frame rearwardly of and adjacent to the bevel gears 59 and 5|. Two bevel gears 53' and 54 respectively are rigidly mounted on the drive shaft 52 and are arranged adjacent to the inner faces of the side walls I0 and I I respectively. The bevel gears 53 and 54 mesh with the bevel gears and 5| respectively.

On the end portion of the drive shaft 52 projecting beyond the side wall ID a sprocket gear 55 is rigidly mounted and a sprocket gear 56 is rigidly mounted on the end portion of the shaft 38 projecting beyond the side wall Ill. A sprocket chain 51 is trained over the two sprocket gears.

On the end portion of the drive shaft 52 projecting beyond the frame side wall I I a comparatively large spur gear 58 is rigidly mounted and a large gear housing 59 is arranged on and secured to the'mainframe F above the drive shaft 52.-

Rearwardly of the gear housing a base plate 59 is secured to the top edges of the side walls I0 and I land a motor 60 is mounted onsaid plate. Preferably this motor is a one and one half horse power internal combustion engine driving the reduction gear transmission contained in the gear housing."

This gear transmission comprises and drives a transverse shaft 6| extending outside of the gear housing. A comparatively small spur gear 62 is rigidly mounted on the end portion of said driven shaft projecting outside of the housing and meshes with the spur gear 58.

On the under edge of each side wall I0 and I I a bearing 63 is secured approximately half way between the rear axle 25 and the transeverse shaft 36. A transverse axle 64 is journaled in said bearings and two-rubber tired wheels 65 are 4 mounted on said axle. The radius of said wheels is of such length that the device is adapted to ride on the rubber tired wheels and the small roller 26 and the roller 39 are arranged above the ground, when the device is removed from the rail 45 but that the tires of the wheels 65 do not touch the ground, when the roller 26 and the roller 39 rest on said rail. v An upwardly and rearwardlyextending handle bar. 66 is secured to the rear portion pf the main frame F facilitating manual moving of the device.

When the device is to be used to move a railroad car, it is placed on a track so that the small wheel 26 and the roller 39 rest on the head of the rail 45. The motor 60 is started driving the roller 39 by means of the spur gears 62 and 58,

.the transverse shaft 52, the sprocket gear 55.

sprocket chain 57, sprocket gear 56 and shaft 38. The wheel I6 of the railroad car enters between the corrugated rollers and is engaged and set into rolling motion by them, since said rollers are rotated by themotor 60; In Figures 5, 6 and 7 a modified form of the car moving device in accordance to the present invention is illustrated and the device as embodied in said figures comprises a main frameMrcomprising two longitudinal side walls 61 .and 68 respectivelyand a base plate 6 9 secured to the top edges of the sidewalls and holding them in position so that they are spaced from each other and run parallel to each other. Adjacent to each end of each side wall a bracket 16 is located. Each bracket Ill has upwardly extending upper flange II, a web "extending at an angle from the lower edge'of. the flange II and a lower flange I3 extending downwardly from the web parallel to the upper flange'II. V

'Ahandle bar I4 is secured to one end portion, hereinafter called the rear end portion, of one of the side walls, for instance the side wall 68, so that it extends rearwardly and upwardly from said wall. A rear axle I5 is rotatably supported by the-lower flanges 13 of the rear brackets I0 and extends beyond one of the side walls, for instance the side wall 68. A front axleI6 is rotatably supported in the lower flanges I3 of the forwardbrackets I6 and extends beyond the'same side wall as the rear axle I5. The two axles are arranged so that their axes are located at the same level below the under edge of the

side walls

61 and 68 and so that they run parallel to each other. 7

On each of the axles I5 and I6 a roller I8 is rigidly mounted having a cylindrical middle portion 19 and outwardly flaring conical end portions or flanges 86 provided on their circumferential surfaces with longitudinal sharp projections or teeth 8| adapted to engage the head of a track rail 82 on which the device is placed. The rollers I8 are located between the oppositely arranged brackets I6 and approximately on the longitudinal center of the main frame M. On the end portion of the front axle I8 projecting beyondthe side wall 68 and on the corresponding end portion of the rear axle I5 a sprocket gear 83 is rigidly mounted.

A gear housing 84 is mounted on the base plate 69 adjacent to the side wall 68 and contains a reducing gear transmission (not shown) adapted to be driven by a motor 85 indicated in broken lines in Figure 5. A transverse shaft 86 forms a part of the not shown transmission and extends outwardly of the housing 84 beyond the side wall outside end portion of the shaft 86 and a sprocket chain 88 is trained over the sprocket gears 83 and 81 so that the rollers 18 are rotated when the motor 85 is started.

A brace bar 89 is secured to the inside surface of each side wall 61 and '68 just in front of the base plate 69 and extends upwardly and forwardly and at an acute angle to the adjacent side wall. A stub shaft 90 is secured to the brace bar 89 adjacent to the side wall 68 intermediate the ends of said brace bar and extends outwardly therefrom. Two sprocket gears 9i and 92 are rotatably mounted on the stub shaft 90 so that the outer gear 92 of the outer sprocket gear 92 is in engagement with the sprocket chain 89.

A shaft 93 extends between and is rotatably supported by the two brace bars 89 and one end portion of said shaft extends laterally beyond the brace bar adjacent to the side wall 68. A sprocket gear 94 is rigidly mounted on said end portion of the shaft 93 and a sprocket chain 95 is trained over the inner gear 92 and the sprocket gear 94.

A roller 91 is rigidly mounted on the portion of the shaft 93 located directly above the rail 82 when the device is placed on said rail. The roller 91 has a cylindrical middle portion 98 from which two conical outwardly flaring end portions or flanges 99 and I09 extend. Longitudinal sharp projections l9! are provided on the circumferential surface of the conical flange 99 and similar projections I02 are arranged on the conical flange I00.

When a railroad car (not shown) is to be moved the device is placed on the rail 82 and is pushed forwardly until the projections on the roller 98 engage the wheel 103 of the railroad car. Since the flange I04 of said wheel comes nearer to the roller 91 than the outer edge of the tread I05 the conical flange 99 of the roller engaging the wheel flange I04 is smaller than the conical flange I00 engaging the wheel tread. The motor is started and the rollers 19 are rotated in clockwise direction. The two sprocket gears 9| and 92 and the roller 91, are rotated in counter-clockwise direction so that the roller 91 exerts an upward pull on the wheel I93 rotating it in clockwise forward direction.

From the foregoing description it is thought to be obvious that a device for moving freight cars constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated.

I claim:

1. In a railway car moving device, a flat elongated frame, an axle mounted transversely of the center of said frame, ground wheels mounted on the opposite ends of said axle, a second axle journalled transversely of said frame adjacent the rear end thereof, a flanged rail engaging roller centered on said second axle, a pair of spaced divergently related brackets sloping upwardly from the forward end of said frame, a shaft journalled in the lower sides of said brackets and having an end projecting laterally outward of one of the same, a V-channeled roller centered on said shaft between said brackets for driving engagement with the rail engaged by said flanged roller, obliquely disposed rollers journalled longitudinally at the inner sides of said brackets to be engaged with the opposite edges of the rim of a car wheel, a prime mover mounted on said frame and operatively connected with said shaft and the last named of said rollers, and a handle bar extending rearwardly from said frame for maintaining the balance of the device on said I rail.
