GUARD-BAIL.

Specification of Letters Patent.

Application led December 20, 1915. Serial No. 67,705.

To all whom t may concern:

Be it known that I, BENEDICT T. GIBBS, Jr., a citizen of the United States, residing at Chicago Heights, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Guard- Rails, of which the following is a specification.

This invention relates to guard rails for tracks carrying moving vehicles, notably railroad rails.

The object of the invention is to provide a guard rail applicable to a track rail for a considerable distance, as over two or more ties, in which the guard rail itself and the devices for securing it in place are made in two or more pieces as distinguished from the one-piece devices of the prior art, so that the guard rail proper may be placed in position, removed and replaced with or without renewal of one of the parts as desired without its being necessary to remove and replace the major parts of the securing device.

The invention consists in a device for carrying out the foregoing objects, which can be easily and cheaply made and installed, which is satisfactory in operation and not readily liable to get out of order. Also in the features and details of construction hereafter more fully described in the specification and claims.

Referring to the drawings, in which simi# lar numerals indicate the same parts throughout the several views, Figure 1 is a plan, and Fig. 2 is a side view of mechanism illustrating this invention inV its preferred form. Figs. 3, 4.and 5 are transverse sectional detail views on the correspondingly numbered lines of Fig. 1. Fig.' 6 is a perspective view of the guard rail proper removed from all other parts. Fig. 7 is a corresponding perspective view of the securing device. Fig. 8 is a sectional and perspective view'showing the relations of the parts in assembled and finally adjusted position. Fig. 9 is a sectional detail view on the line 9 9 of Fig. 4, and Fig. 10 shows the device provided with a modified construction of slot 32.

The device of this invention is applicable to any sort of a'rail over which a vehicle passes, and is hereconventionally shown as applied to the rail 10 resting upon ties 12, in the ordinary manner.

The guard rail, as a -whole,.l4, illustrated iupllfg- .6, iS, brgadly speaking, secured in place through the "i agency of the base plate 16 carrying the brace blocks 18, shown in perspective in Fig. 7. In the particular case here illustrated, this base plate 16 is made in one piece to extend under the rail 10 over four ties 12, but obviously the length of this base plate may be varied without departing from this invention. The brace blocks 18 are rigidly secured upon the base plate 16 either by belng made integral therewith, as shown, or by any other suitable means. They are preferably connected trgether by a vertical plate or flange 20 having therein at suitable intervals bolt holes 22. TheV base plate 16 is securable in adjusted position transversely of the rail and lengthwise of the tie through the use of spikes 24 passing through the angularly notched adjusting holes 28 provided for the purpose in the manner well known in the art.

The top of each block 18 is cut away to form the horizontally inclined or wedge surface 30, the inclination of each of these wedge surfaces being substantially the same and preferably, though not necessarily, at substantially the same height above the base plate 16.

Extending horizontally through the inner face of each brace block; viz., the face adjacent to the rail 10, and below the adjacent wedge surface 30, is a slot or recess, in the case illustrated in the principal figures the U-shaped recess 32 having its upper face 33 extending parallel to the base plate 16. A modified form of this slot is shown, at 80 in Fig. 10, in which the upper face is marked- 33a. These slots are preferably, though not necessarily, made with their upper faces 33 or 33a substantially the same height above the base plate.

The guard rail 14, heretofore referred to"l in general terms only, is preferably made in' angular form with a horizontal tread flange. 40 extending from a vertical flange 42. On the under surface of this tread flange 40 are a plurality of depending blocks 44 having lower horizontal inclined or wedge surfaces 46 corresponding in angularity to the surfaces 30 of the brace blocks heretofore described. These surfaces 46 just described are so located on the underside of the flange 40 of the guard that when the parts are in" assembled position, one of these wedge surfaces 4.6. besseres; @e adjacent .Wedge Surf;

face 30 on a brace block, as clearly shown in Fig. 9. l

vExtending from the vertical flange 42 of the guard rail and below each wedge sur-v face 46, heretofore described, is a horizontally extending fiange 50 of such a size, shape-and location that it readily enters and slides in thehorizontal slot 32 or S0 as the case may be, in the adjacent brace block. As these horizontal flanges 50 Aare like the slots 32er Y100 parallel-to the base plate 16 and the wedge `

surfaces

30 and 46 are inclined thereto, it is entirely obvious that it only takes a relatively short movement of the guard rail 14 horizontally to the right,

as viewed in Fig. 9, to effectually wedge the guardrail onto the brace blocks, and that corresponding movement of the guard rail in the opposite direction'will release this locking effect so that so far as the partsv heretofore described are concerned at least, the guard rail may be removed from the brace blocks.

In order to insure the proper positioning of the guard rail 14 with reference to the rail 10 and upon the brace blocks when the parts are in assembled position, the guard rail is provided with a plurality of horizontally extending separating lugs 54 located on the rail side'of the guard rail, extending to the rail and engaging it under the rail head 56, as clearly appears in Fig. 4. In the particular case here illustrated, only two of these members 54 are provided and they are located directly opposite to the two central brace blocks. The position and length of these members 54 along the rail is not material to the operation of the device. The guardrail is, as usual, bent outwardly at its ends, as shown in Fig. 1, and is pref# erably provided with end foot guards and 62 integral therewith. The ends of the guard rail are secured to suitably located ties by the brackets 64 and spikes 65 in the ordinary manner.

' The vertical flange 42 of the guard rail is so located with reference to the other parts heretofore kdescribed that, Vas clearly appears in Fig.'5, it lies inside of and is slidable horizontally Yalong the plate or flange 2O connecting the brace blocks. and it isprovided at suitable intervals with vholes 6,8 adapted, when the parts are in finally assembled position, to register with the holes 22, heretofore described, so that one or more bolts may be inserted through these sets ofholes, as shown, to rigidly secure the parts in position and prevent the guard rail wedge surfaces 46 from backing off from the brace block inclined surfaces 30. In the drawings, three of these bolts 70are shown, but'a less number may be used without departing from the invention.

jIt should be noticed that the members 5'0 altrettanta-aie .para aait-leerse pese tion, engage the brace blocks heretofore described to prevent any vertical movement of the guard rail with reference to them are only slightly longer than the brace blocks vthemselves and are not as long as the distance between the respective brace blocks, the result being that when the guard rail has been moved from the position shown in Figs. 1 and 2 to the leftuntil these members 50 are clear of their adjacent brace blocks, the guard rail can be lifted vertically upward and-removed entirely from engagement with the rail and the brace block.

In the operationof installing the device, the base plate 16 with the lbrace blocks at` tached thereto is inserted under the rail 10 and adjusted as near as may be to what is supposed to be its final position. The guard rail 14 is then held with the members 50 between the brace blocks, and then lowered into position with the upper flange 40 resting upon the tops of the brace blocks, the guard rail being tilted in the lowering operation to allow the members 54 to pass under the rail head 56. The guard rail and attached parts is now moved to the right until the parts assume the position 'shown in Figs. 1 and 2, the guard rail being driven horizontally to the right as hard as may b e necessaryto insure proper engagement of the respective wedge surfaces 30 and 46, after which the bolts 70 are put in place. In practice, it may be desirable not to bore either the holes 22 or the holesv 68, depending upon the material of which the respec tive parts are made, until the foregoing ad-v justments have been initially made. During the foregoing positioning yof the parts', any adjustments of the brace blocks needed may be made by changing the locations of the spikes 24 in the slots 28. When everything is finally adjusted, the brace blocks are finally secured in place by the driving of theV spikes 74.

If, at any time, the guard rail needsrepair or replacing, it can be removed by first'v taking out the bolts 70, driving the guard rail to the left, as viewed in Figs. 1 and 2, and lifting it out. all as has heretofore been more fully described.
