13e it known that 1, ALFRED F. BERNARD, a'

citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Railroad-Construction Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a novel apparatus for use in constructing the roadbed for a railroad where more or less filling has to be done, the object being to do away with the necessity of the false trestle-work which is commonly employed and at the same time provide an apparatus of bridge-like construction which can be continuously advanced as the filling proceeds; and it consistsin the features of construction and combinations of parts hereinafter fully described and claimed.

In the accompanying drawings illustrating' my invention, Figures l and 1b are a side elevation of an Vapparatus constructed in accordance with my invention. Figs. 2 and 2b are a plan view of same. Fig. 3 is a detail longitudinal section on line 3 3, Figs. 2a and 2b. Fig. 4 is a detail longitudinal section, on an enlarged scale, on line 4 4 of Fig. 2l. Fig. 5 is a View similar to Fig. 4, with some ofthe parts removed and others in various positions. Fig. 6 is a detail cross-section on line 6 6 of Fig. 5. Fig. 'is a detail longitudinal section on the line 7 7 of Fig. 2a. Fig. 8 is a crosssection on line 8 8, Fig. 1b. Fig. 9 is a crosssection on line 9 9, Fig. 2. Fig. 10 is a detail cross-section on line 10 10, Fig. 2*. Fig. 11 is a detail cross-section on line 11 11, Fig. 2b. Fig. 12 is a detail cross-section on line 12 12, Fig. 22.

My apparatus is especially useful iu cases where very deep fillings are yrequired and where the construction of false work'would be very expensive. It is of bridge-like construction and is designed to be assembled at the edge of the fill or the end of the dump and be projected out over the space where it is desired to dump the filling material, the cars as they are emptied being pushed out on the structure until all the cars in the train have been dumped or until the structure is full of empty cars.

Referring now to said drawings, 1 represents the permanent road-bed, 2 being approximately the end of the fill and the position where it is desired to dump the filling material.

My apparatus comprises a frame 3, built up of the two an-gle-irons 4, secured to

crosspieces

5, 5, 6, 7, and 8, the upright flanges of said angle-irons being spread on said supports to the gage of the track 10. of said angle-irons are tapered and adapted to enter between the T-rails 11 of said track 10 Said frame 3 is strongly braced by means of the diagonal braces 11a, which are secured to said

cross-pieces

5, 5, 6, 7, and 8 between said angle-irons 4. Said frame 3 is adapted to be advanced or pushed forward from time to time as the filling proceeds and is supported in its position over the fill by means of three pairs of

cables

12, 13, and 14,'which are carried over the top of a suitable support 15, which is erected back from the edge of the fill, the rear ends of said cables being firmly secured in any suitable manner. The forward ends of said

cables

12 and 13 are secured by means of chains 16 and turnbuckles 17 to shafts 1S and 19, which are rotativelymounted on the under side of said frame 3. Said shaft 18 is mounted near the forward end of said frame and said shaft 19 near its rea-r end. The forward ends of said cables 14 are secured by means of turnbuckles 2O and chains 21 to a cross-beam 22, which is slidiugly mounted under said rails 11 to the rear of said frame 3 by means of clips 23 and is. located at about the point where it is desired to dump the filling material. The forward end of said frame 3 is held sidewise by cables 24, which are secured to the outer ends of said cross-beam 22. Said frame 3 is slidingly mounted on said rails 11 by means of the shoe-like members 25,l

which are secured .ou said cross-pieces 7 and 8 and in which the outer flanges of said rails 11 are adapted to fit. Said angle-irons 4 are The rear ends 9 irons. Three pairs of heavy clamps 27 are provided to draw the rails 11 and the frame 3 firmly together and are located to the rear of said cross-piece 8 and adjacent said shaft 19 and are adapted to clamp said shoes 25 and rails11 firmly withthe said angle-irons4ofsaid frame 3, turnbuckles 23 being provided for the purpose of opening and closing said clamps. The jaws 29 of said clamps 27 are adapted to fit around the outer edge of said shoes 25, and the upper ends of said jaws are adapted to bear on the outer side of the ball of the T- rail 11, thus effectually bracing up said rails. The openings 30 in said jaws 29 of said clamps 27 are wider than the combined width of said T-rails 11 and angle-irons 4, thus leaving a space 3l, which is adapted to receive awedge 32 as an additional means of securing the various members rigidly together. Said opening 30 also allows said clamps to be opened and said frame 3 loosened from said rails 11, so that said frame 3 may be moved on said rails. Said angle-irons 4 are adapted to lit the contour of the surface of the inner side of said rails 11, so that when they are clamped together they will both be firmly braced.l Said rails 11 are secured together end to end in the usual manner by means of fish-plates 33 and bolts 34; but no plates are placed on the inside of the rail, and the bolt-holes in the flange of the rails 11 are countersunk, so that the inside surface may be free of projections where said angle-irons 4 rest against same. As said frame is moved forward and the joints between rails 11 are freed from said angleirons the countersunk head-bolts 34 are removed and a fish-plate placed on the inside of the rails and ordinary bolts put-in place, thel rails being held in their relative positions meanwhile by means of the cross-bar 35,which is adapted to engage the iianges of said rails. Said cross-bar is -moved forward with said frame 3 by means of the hooks 36, which are secured. to the cross-bar 37'of said frame 3 and are adapted'to enter holes in said bar 35 and drag it along with said frame. lVhen said bar 35 reaches a joint in its forward movement it is freed from said hooks and allowed to remain atthe joint until said frame 3 has been moved forward far enough to free the bolts 34 of the joint from the ends of said angle-irons 4, when the change in the bolts and fish-plates can be made. Said frame 3 is adapted to be moved forward by means of a jack 38, which is slidingly mounted centrally between said rails 11 to the rear of said frame 3, being mounted in a member 39, which is secured to said cross-piece 22. Said jack is held against rearward thrust by means of the clamps 40, which are adapted to grip the fianges of said rails 11 in advance of said jack. Said jack is adapted to push on a longY rack 4l, which is slidingly mounted beneath said jack and is adapted to be forced against a member 42, which is secured to the'cross-piece 8 of said frame 3. The forward end of said rack is provided with an upturned end and has a centering-point 42, adapted to enter a recess in the end of said member 42 in order to prevent it from being displaced when pressure is being applied. A member 43 is provided having teeth 44 on`itslowersurface, adapted to engage the teeth 45 of said rack, and is adapted to be firmly clamped in its desired position on said rack by means of the tapered band 46, which is adapted to be wedged in place around said rack and said member 43. The rear end of said member 43 is raised to adaptit to receive the pushing-head of said jack 38. Said jack is removably mounted on a member 47, which is slidingly mounted on said member 39, to the end that when it is not being used it may be removed, so that it will 4not present any hindrance to the movement of the cars. Said jack is held in place on said member 47 by means of the bands 48, which are shown in Fig. 5 in their depressed position, and it pushes against a back-stop 49, which is also mounted on said member 47, being pivotally mounted on the rear end of a U-shaped bar 50. Said bar 50 is mounted in said member 47, its free ends extending forward beneath said jack and being formed into hooks 5l, which are adapted to engage with a U-shaped member 52, the free ends of which are secured to said clamps 40. Said back-stop 49 is adapted to be held in position, as shown in Figs. 3 and 4, by means of the two pairs of

braces

53 and 54, which are pivotally mounted on the outer ends of a pin 55, which passes through said back-stop at its upper end, the free ends of said braces being turned inwardly and adapted to enter holes 56 in the sides of said member 41. Vhen the spring-cotter 57 which holds said pin 55 in place is removed, said braces 53 and 54 may be separated and withdrawn from said member 47 and turned back with said back# stop 49 to the position shown in Fig. 5 for the same purpose that said jack is` removed.

`To hold said shafts 1S and 19 against theA strain of said

cables

12 and 13 ratchet-wheels 58 are mounted on same, and dogs 59, piv otally mounted on said frame 3, adapted toen-y IOO IIO

foundation-piece G2, on which are erected the two uprigh'ts 63, which support on their upper endsthe cross-pieces 64 and 65, on the outer ends of which the saddle-blocks G6 are supported. providedwith three cross-grooves G7,- each of l Said saddle-blocks 6G are each which is adapted to receive one of said

cables

12, 13, or 14. Pins (3S are provided to pre-` Y .vent said cables from get-ting out of their grooves, said pins being entered under staples 69. Said vuprights 63 are held in place by means of hooks 70, which are pivotally mounted on said uprights and are adapted to j engage staples 7l, which may be driven into the ends of suitable ties. Irlooks 72 are also mounted on said uprights and are adapted to engage with a U-shaped bolt 73 in the 'center of said

cross-pieces

64 and 65, said bolt 73 being held in place by means of the plate 74 and nuts 75. This construction provides for the taking apart of said support l5 for its removal and erection.

In operating my device, after it has been erected in position on the edge to the space which it is desired to till the frame 3 is pushed forward from time to time as the work proceeds. To do this, the jack 38 is put in place and the clamps 27 are loosened, when said frame can be forced forward on said rails Il. As this is done said shafts 18 and 19 are allowed to rotate by means of said levers 60, thus letting off some of said chains 16 and preserving said frame in its level position. Said member 39 is secured to said crosspiece 22 by means of a bolt 76 and slot 77, thus permitting said cross-piece 22 tofollowsaid frame. When said frame has been forced to its desired position, U-shapedbrace-bars 78 are put in place in holes 79 in the upright portion of said angle-irons 4, just in advance of the forward end of said T-rails Il, and said frame 3 is drawn back, so that said U-braces will take the thrust. The upright portion of said angle-iron 4 is provided with a series of the holes 79, so that said braces 78 may always be placed close t0 the ends of said T- rails Il. As said frame 3 is advanced said braces 7S recede from the forward end of said frame 3, and finally there will be sufficient free space on the forward end of said frame 3 to connect in an additional T-rail to the end of said track l0, when said U-braces 78 are carried forward. Extra rails 8O may be carried on the outer ends of said cross-pieces 5, 5, G,V and 7, stakes 8l being provided to prevent same from being thrown oft of said crosspieces. Stops S2 are provided, secured to the forward end of said angle-irons 4, to prevent the dump-cars from being pushed off of the end of said frame.
