CAR OR ENGINE REPLACER.

SPECIFICATION forming part of Letters Patent No. 792,977, dated June 20, 1905.

Application filed March 18, 1905. Serial No. 250,849.

To all whom, it may concern.:

Be -it known that I, FREDERICK J. FEWINGS, a citizen of the United States, residing at Duluth, inthe county of St. Louis and State of Minnesota, have invented new and useful Improvements in Car or Engine Replacers, of which the following is a specification.

This invention relates to car and engine replacers; and the object thereof is to provide a car and engine replacer, hereinafter more speciiically referred to, which will readily and efficiently replace a car or engine whether it is run forward upon or backed upon the replacer.

Primarily the invention resides in certain improvements hereinafter more specifically set forth upon the forms of car and engine replacers described and claimed in Letters Patent granted to me April 12, l1902, No. 706,542, and April 19, 1904:, No. 757,604; and to this end the invention aims to provide a car or engine replacer which shall be simple in construction, strong, durable, eflicient in its use, and comparatively inexpensive to manufacture.

IVith the foregoing and other objects in view the invention consists of the novel construction, combination, and arrangement of parts hereinafter more specifically described, and illustrated in the accompanying drawings, which form a part of this specification, and wherein is shown the preferred embodiment of the invention; but it is to be understood that changes, variations, and modifications can be resorted to which come within the scope of the claims hereunto appended.

In the drawings forming a part of this specification, wherein lilIe reference characters denote corresponding parts throughout the several views, Figure 1 is a perspective View showingthe operative position of the replacerblocks with respect to track-rails. Fig. 2 is a top plan view of the inner replacer-block. Fig. 3 is a top plan view of the outer replacerblock. Fig. 4 is an inverted plan view of the inner replacer-block. Fig. 5 is a like plan view of the outer replacer-block. Fig. 6 isa View looking from one end of the inner replacer-block. Fig. 7 is a'section on the line 7 7 of Fig. 2. Fig. 8 is a section on line 8 8,

Fig. 2. Fig. 9 is a section on line 9 9, Fig. 2. Fig. 10 is a section on line 10 10, Fig'. 3. Fig. 11 is a section on line 11 11', Fig 3. Fig. 12 isa section on line 12 12, Fig. 3. Fig. 13 is a section on line 13 13, Fig. 3. Fig. 14: is a section on line 14 14, Fig. 3. Fig. 15 is a perspective view of one of the inner corners of either of the blocks, showing' the cut-away portion to permit of straddling the base of the track-rail section. Figs. 16, 17, and 18 show in plan modified forms of blocks.

Referring to the drawings, the inner block will be referred to generally by the reference character l, and the outer block by the reference character 2. Both of the blocks are hollow, and each is formed of two side walls and a top wall. Each of the blocks is strengthened through the medium of a plurality of transversely-disposed braces 3, arranged within the blocks, intermediate of the ends thereof, and formed integral with the inner face of the side walls and the top wall. In Fig. 1 of the drawings the inner block 1 is shown in operative Aposition with respect to the track-rail section t, and the outer block 2 is shown in operative position with respect to the track-rail section 5.

The inner block 1 has a curved upper surface with the intermediate part thereof inclined downwardly toward the inner side of the block, and the end portions of said curved upper surface are approximately at right angles with respect to the intermediate part of said surface, said curved surface at its inner part extending in an arc of a circle and at its outer part extending in an arc of a circle of less radius than the' arc at the inner part. The manner in which the inner block 1 is constructed, so that the foregoing curvature of the upper surface of the inner block can be obtained, is as follows: That side wall of the inner block 1 which is arranged nearest the rail-section i and indicated by the reference character 6 is termed the inner wall, and that part of the upper surface of the inner block 1 which is nearest the track-rail section I is termed the inner7 part of the curved surface of the block. The side wall 6 is substantially segment-shaped in contour, so that the top edge 7 of said side wall 6 will extend in an are of a circle. That side wall of the inner block 1 which is farthest away from the rail-section 4 is termed the other side wall 8, and that part of the curved surface of the block which is farthest away from the track-rail 'section 4 is termed the outer part of the curved surface. The side wall 8 extends toward the side wall 6 at an inclination and is what may be termed bowshaped from end to end and is of much greater' height than the side wall 6, so as to form a bow-shaped flange 9, arranged with respect to the outer part of the curved surface of the inner block 1, said flange 9 projecting above the curved surface ot the block and said curved surface terminating in said Harige 9. The top wall of the inner block 1 is indicated by the reference character 10 and is of convexed curvature longitudinally throughout, so that the upper face of said top wall 10 will be curvilinear in contour. The end portions o1' the top wall 10 at their outer sides curve away from the inner sides, or, in other words, the outer side of the top wall conforms in contour to the side wall 8. The top wall 10 is so constructed that the intermediate portion thereoil is inclined downwardly toward the side wall 6, while the end portions of said top wall are inclined at approximately a right angle to the intermediate portion. By such construction the curved upper surface ofthe block will have an intermediate part which is inclined downwardly toward `the side wall 6 and end parts inclined approximately at right angles with respect to said intermediate part. AWhere the upper surface of the top wall 10 terminates in the flange 9, it extends in the arc of a circle, but of less radius than the top edge 7 of the side wall 6, the said top edge 7 being what may be termed the terminus of the inner part of the curved surface of the top wall 10. The lower face of the ends of the top wall is cut away, as at 11, to permit of mounting the block 1 upon the base of the rail-section 4, and said inner face ot' thetop wall is further provided with spurs 12 of any suitable shape and which are adapted to pierce the ties to assist in holding the block 1 rigidly in position. rlhe side wall 8 at its bottom is provided with an outwardly-extending ange 13, which has formed therein a series of openings 14, registering with a series o't'recesses 15, formed by the depressed portions 16 in the outer face ot' said wall 8. The recesses and openings are adapted to receive spikes or other suitable fastening means which engage in the ties o1' the tracks for securing the block 1 thereto when the latter is arranged in its operative position. The bottom ofthe Wall 8 is provided with spurs 17, which are adapted when the block 1 is in position to pierce the ties, so as to assist in retaining may be termed a hump of .convex purvature longitudinally as well as transversely, thehump incliningdownwardlyfromthe outer to the inner side of the block 2 and which is' formed by constructing a portion of the block of reversed compound curvature longitudinally and the remaining portion of the block of convexed curvature longitudinally. That portion ofthe block of convexed curvature longitudinally otherwise than that part into which the hump merges is separated from that portion ofthe block of reversed compound curvature by a pair of diagonally-extending ribs, which terminate in each side oi' the hump. The specitic manner in which the outer block 2 is constructed so as to obtain the curvature referred to is as follows: That side wall of the outer block 2 which is arranged nearest the track-rail section 5 is indicated by the reference character 18 and is termed the inner wall, which is slightly inclined, so as to project away from the railsection 5, and is substantially segment-shaped in contour, so that the top edge 19 of said side wall 18 will extend in the arc of a circle. The

side wall of the outer block 2 which is farthest away from the rail-section 5 is termed the outer side wall 2O and extends toward the side wall 18 at an inclination, is oi' much greater height than the side wall 18, and has its top edge of reversed compound curvature, as at 21. rlhe top wall of the outer block 2 is indicated by the reference character 22 and has a portion thereof of convexed curvature longitudinally and said portion at a point removed from each side of the center spreading outwardly, so that the ends will be enlarged. The other portion of the top wall is of reversed compound curvature, so as to form the hump 23 of convexed curvature longitudinally as well as transversely, and said hump 23 is inclined downwardly toward the inner wall 18 and merges into the intermediate part of thatvportion of the top wall of convexed curvature longitudinally. The top wall 22 is further provided with a pair of diagonally-extending ribs 24, merging at their upper ends into the hump and further separating the ends of that portion of the top wall of reversed compound curvature from the spreading ends of that portion of the front wall of convexed curvature longitudinally. The upper end of the ribs 2.4 are not blunt, but are cut away, as at 25, forming at the point where they merge into the hump flattened portions. The lower Jace at the ends of the top wall is cut away, as at 26, to permit of the mounting ot' theA block 2 upon the base of the track-rail section 5, and said lower 'face of the ends of the top wall is further provided with spurs 27, which are adapted to pierce the ties to assist in retaining the block in position. The side wall 20 at its bottom is provided with an outwardly-extending ange 28, having openings 29, registeringwith recesses 30,*`orming.

passages for holdfast devices for securing the block 2 in position. The lower face of the flange 28 is formed with spurs 31, which are adapted to pierce the ties to assist in retaining the block in position.

By constructing the blocks in the manner as set forth the wheels are prevented from passing completely over them, as the rib on the inner block and the ribs on the outer block guide the Wheels and aid the sluing power of the incline, so there is but one place the wheels can go namely, on the rails. The blocks are so constructed as to be capable of withstanding the weight of the heavy locomotives and are yet light enough to be handled easily. rI`he blocks are high enough to accomplish their work, butV do not interfere in any manner with the underriggiiig of the cais or locomotives. rl`he ascent of each of the blocks is gradual, yet the throwing power is sure, and, fuithermore, the blocks can be used on bridges, trestles, curves, boarded crossings, and frozen ground. The providing of the hump on the outer block in a manner as shown causes the wheels to be rerailed even if they should mount the block on the outer side of the ribs, for the reason that the curvature of the hump is such that when the wheels mount it they will be caused to slide toward the inner side of the block so as to be rerailed.

The outer as well as the inner block is provided near each end'with a handhold, as at 32 33. These handholds depend from the inner face of the top of their respective blocks and are preferably cylindrical in cross-section and of such size that they can be readily grasped by the trainmen. The handholds 32 33 are in the form of handles and are preferably interposed between ythe ends of the blocks and the braces 3. The liandholds 32 33 preferably extend in a vertical man ner and in parallelism with theV braces 3.

In the modified construction shown in Fig. 16 the block is indicated bythe reference character 34, and in lieu of the ribs 24 the grooves 35 are provided, which terminate in the hump 36. Otherwise than that as stated the construction of block shown in Fig. 16 is the saine as that shown in Fig. 3.

ln Fig. 17 the block is indicated by the reference character 36 and is the same as that shown in Fig. 16, with the exception that a single groove is employed and which is indi- ()n the opposite side of the block a rib 39 is employed in lieu of the groove.

In Fig'. 18 a block similar to the construction shown in 17 is set up, but with this exception, that the rib and groove are reversed. rI`he rib is indicated by the reference character 40, the groove by the reference character 41, and the block by the reference character 42.
